What could he say? He had a good life. This was just how things went for him. His first night in Tanzania with the summer research team from UNC and he'd already scored his first quality piece of ass. She was maybe a little flat chested for his liking. But she had pert upturned tits and long dark nipples that stood out on her pale skin, long thin legs and arms, tight stomach, and that upturned nose that made her look a little snobby, a little superior. That's what had really gotten him. She was probably the hottest girl on the trip, actually, but she wasn't the only hottie in the group by any means. Yeah, it was going to be an interesting four weeks. Three guys and six girls, all undergrads from UNC, conducting intensive field work on primate behavior in the wild, chimpanzees to be precise. Nine girls, come to think of it, if you counted the graduate student, the postdoc, and the assistant professor—Kate Morgan—who would be leading the team. They were staying in a hotel near the beach in Dar es Salaam for a few days for a crash course on research methods in the field, but then they'd be heading out for the mountains and the rain forest, deep in the interior. Yeah, I have a good life, Chad reflected, as his new partner leaned forward and slid her sweaty body up the length of his. The humidity here was really something! She was grinding her hips now in smooth, slow strokes. Chad knew that most guys would kill to be as successful with the ladies as he was, and he couldn't help feeling a little smug about it, even arrogant, though he was basically a nice guy. He wasn't a full-time cooze hound or anything, like some of the frat guys he knew. Most weeknights he was too exhausted from soccer practice and hitting the books to do much partying. His talents with a soccer ball had been his ticket out of the Appalachian foothills—a full ride to play for his beloved Tar-heels!—and he wasn't going to squander it. His kids would have all the advantages in life he'd been denied, all the ones his mostly well-off classmates took for granted. But on weekends, when Chad did have time for his other favorite "sport," he was very good at it indeed. And not just because of his boyish good looks and soccer player body, all jet black hair, blue eyes, and long lean muscle. It wasn't like girls just threw themselves at him, like they did with the basketball and football players. He had to show a little interest and give a little effort. It didn't hurt that he was unusually intelligent for a "dumb jock," a double major in anthropology and biology, and an excellent student at that. He liked to think that his studies had given him a keen insight into human behavior—especially female behavior—and the deep, unconscious forces that drove it. Girls were so predictable, and the right method could easily produce the desired results. For example: 1) Identify a hot girl in the lecture hall or lab; 2) ask her questions and actually listen to the answers; 3) invite her and her friend to a party at the athletics dorm; 4) flirt with her friend; 5) tease the hot girl about her looks or brains while smiling a lot. Before you knew it her body would be sending out all the expected signals, on the dance floor or just talking in the corner, or on a couch. Tits forward slightly, almost imperceptibly if you didn't know what to look for, ass sticking out, hips swaying subtly, eyes bright and receptive. It was almost as if they had a sign over their head that only he could read: "available for mounting." It almost never failed. Especially with the brainy, hot girls that Chad preferred, and that were in such abundant supply in Chapel Hill. All those gorgeous southern belles with impeccable grades and plans for med school, law school, or business school. Chad relaxed into the mattress and closed his eyes as the sperm welled up in his balls. He was close, but wanted to prolong the pleasure. He sat up quickly and put the girl on his lap facing him, making sure his cock stayed buried deep inside her. Yes, girls were predictable. And thank God for that! Because Chad truly loved to fuck them. And he was truly good at it. This was not just because he had a big dick, though he did. Ten inches, and thick as hell, with a broad bulbous head. And it was not just because had an amazing body either, though he was long, lean and ripped. No, it was mostly because he took such genuine pleasure in the chase, and such twisted delight in driving girls past their accepted limits. He liked to make them do things that they hadn't realized they would do, that they couldn't quite believe they were doing. Fucking him on the first "date" (if you could even call them dates). Fucking him when they weren't sure they really liked him, or he really liked them (he was always teasing and undermining them in subtle ways). Fucking him in positions they hadn't tried before, even with their long-term boyfriends, maybe even their current long-term boyfriend. Letting him cum on their tits or in their mouth. Letting him fuck them unprotected. Letting him cum inside. That was the absolute hottest! As sweet as he seemed, and in fact was most of the time, Chad definitely had a little sadistic streak. Not that the girls ever complained. They almost always got off, most of them just from penetration. Take Elise here. She was definitely about to blow. "Ugh, Chad, o my god, ugh, fuck." Chad stuck his fingers in her mouth roughly with his left hand, while his right hand reached around and pulled her ass cheeks apart. His teeth bit hard into her pale neck. She'd been pretty easy to get in bed, Chad reflected, though she'd seemed a little stuck up and distant when he first met her on the long plane trip from Raleigh. He'd ended up sitting between her and her friend Courtney for most of the trip, and most of the time he'd flirted with Courtney. She was a good-looking bottle blonde (maybe a little slutty?) with big soft tits in a tight scoop neck t-shirt. But all the while he'd made sure to keep asking Elise questions too, and to needle her a little about her answers, smiling his boyish smile as he rolled his eyes at her. She'd run cross-country at some preppy "Day School" outside Durham ("no kidding?"). But now she'd given up running seriously to focus on her classes in pre-med ("really?"). She'd rushed a popular sorority in her first semester ("interesting!") and met her boyfriend at a fall mixer, a finance major ("sounds like a solid provider"). Chad liked her blonde hair pulled back in a short pony-tail, and her cute little nose turned up at the end. He liked her pale blue eyes with the half-disdainful, half-mischievous expression. By the time they'd landed in Dar es Salaam and got to their hotel they were all exhausted. But the whole group stayed up drinking in the lobby bar. Well, the undergrads anyway. Then one of the guys scored some weed from one of the bell hops and a smaller group moved out to the patio to smoke a joint. They sat there for a while, listening to the tide rise slowly in the darkness behind them, just beyond the palm trees. He'd noticed that Elise wrinkled her nose at the joint when it came around to her, until Ellen elbowed her in the ribs and called her some nick-name, he couldn't hear what. Soon everyone was heading up to their rooms to grab their swimsuits for a midnight swim (Courtney's idea). And before they knew it they were in the surf splashing and making playful comments about each other's swim attire. Chad had made sure to slip in a few off-color compliments about Ellen in her polka dot string bikini. And she really did look pretty good. But Elise looked fantastic in her little blue two-piece. And she knew it. Smallish tits sticking straight up at the stars. Long nipples that poked obscenely through her wet top. Those skinny runner's arms and legs. Wide hips that flared out dramatically from her small waist. And best of all, a truly spectacular ass. Chad kneaded her ass with his big hands as the little preppy girl bounced excitedly on his shaft, taking the whole length of him in quick strokes. He stuck his tongue down her throat and reached a finger toward her anus. It had been almost too corny the way they'd all ended up drunk and half naked, Chad thought to himself, joking and splashing in the warm surf. So predictable, really, though still a blast. It was like they were all just playing out some script they weren't aware of, and that had been written for them long ago, as the tide kept rising all around them. Chad had waded over to Elise standing alone in the moonlight (a full moon, of course). She was sulking a little from the attentions he'd been giving Courtney (right on cue!). Up close her tits were much fuller than he'd thought at first. Smallish, yeah, but definite handfuls. He'd leaned in for a drunken kiss. "What about Courtney?" "What about that boyfriend?" She'd parted her lips and stumbled into him. And now he was fucking her in his plush hotel bed (his roommate for the trip had hooked up with Courtney, conveniently enough). Chad reached up with his left hand and pushed Elise's chest away from him a little, rubbing his palms over her sweaty breasts and feeling her nipples stiffen. He pinched them hard. Elise tilted her hips a little and her pussy opened to him with the new angle. Christ this little preppy girl really knew how to fuck! He'd had a feeling about that, and he was not disappointed. He seemed to have a sixth sense about such things. She leaned back on her hands and looked straight at him with that stuck up expression, rotating her crotch in quick tight circles. Chad lunged forward and licked the sweat off her tits as he pushed her back on the bed, the heat building in his testicles. She threw her legs around his waist and rode along with him as he gave her a serious pounding. "Ugh, Chad, fuck me, ugh." This was some of the best sex he'd had in a while, truth be told. He'd been so busy at the end of spring term, with double practice sessions and cramming for exams. It would be perfect, actually, if he could just slip off this stupid condom. He knew it was sort of wrong, but he found it so much hotter like that, especially when the girl got carried away and let him cum inside her, maybe even asked him to. It wasn't just that it felt so much better. Though it did. It was more the thought of it. All these privileged girls, with their whole lives planned out ahead of them losing control for once, doing things that their rational mind told them not to, as their primate brain took charge of their bodies. Were they seeking out Chad's obviously successful genes, their own genetic programming overcoming their disgust for his hillbilly accent? Unfortunately, it was harder to get girls to fuck him bareback now, at least the brainy, straight-laced ones he liked best, and that he'd be willing to take the risk with. He'd developed a reputation as a real player. Elise had put a rubber on him as soon as they'd gotten back to his room, almost like she'd heard about him (she probably had) and wanted to be absolutely sure she wouldn't lose control. It felt better for girls too, after all. They always said so. He'd have time to work on Elise though. They would definitely be fucking again, probably later that night. Chad closed his eyes and thrust into her deeply as his balls contracted and emptied. Part 2 Later that night, after they'd had sex a second time, Chad lay awake thinking about how much he was looking forward to this trip (Elise had woken him up with a hand job and they'd ended up fucking doggy style—again with a condom). It was partly because of all the pussy he was counting on getting. Definitely with Elise again. Definitely with Courtney and a few of the other undergrads he'd flirted with at the bar last night. Hell, maybe even with the hot post-doc, Karin, who'd been his TA for "Evolutionary Biology." All the guys in the class had been crazy for her. Chad had made a point of signing up for her lab section in particular after looking up the different instructors on ratemyprofessors.com. Karin had a blazing chili pepper next to her name and a steady stream of enthusiastic comments underneath it, many of them about her looks and personality. "She is so fine it's distracting! And sweet too!" "Smart, sassy, and great body." "I'm a straight woman and even I think she's hot!'" Of course he'd looked her up on Facebook right away. No bikini pictures, alas, but a couple of pretty decent shots of her in a tight t-shirt and short running shorts on top of some mountain with her boyfriend. She was just slightly on the chunky side, maybe, but definitely hot. One of those dark Jewish princess types he'd never encountered before he came to UNC. They didn't have those in Appalachia. He'd jerked off a couple of times since then imagining the full rack so obvious beneath her t-shirt ("Nice rack" had been one of the racier comments about her). She was what, 26? Only seven years older than him, and probably not that much more experienced in the sack. She'd been with her boyfriend (fiancé actually, and a successful psychologist at Duke) since high school. You could tell by the way he showed up in all her old profile pictures. In class you couldn't see much of her body beneath the white lab coat she wore most days, but a couple of times when she took it off at the end of a long lab session, jutting her chest out as she slipped the coat off her shoulders . . . wow! Every male in the room took notice, praying they wouldn't get caught. He imagined he'd be getting a lot of good look at her assets in the weeks ahead. He felt himself harden again as he pictured those short shorts clinging to her in the humid mountains . . . just in front of him on a steep trail . . . swaying her ass in his face . . . so close he could almost smell her. Yes, the female talent on the trip would be an added bonus. But Chad was mostly looking forward to studying the chimps. Truthfully. He'd been kind of obsessed by chimps since he took an advanced seminar with Professor Brian Phare last fall on "Sexual Behavior in Human and Non-Human Primates." He was such an awesome guy and the subject was riveting. Chad was even considering going to graduate school for it, if a career in Major League Soccer didn't work out. Professor Phare was that inspiring. Pushing forty now and a tenured professor with several published books to his name, he'd been a scholarship kid like Chad at Berkeley back in the day. He'd even tried out for the soccer team there, but hadn't made the cut. The way he explained things really shifted Chad's perspective on life. Human beings think that they act with all this conscious will and intention. But in some areas, especially sexual behavior and what the Professor called "mating systems," this idea of free will doesn't really hold up when you study it logically. We're closer to chimps and bonobos then we are to our own arrogant visions of ourselves as walking gods. Either we're deluding ourselves about free will and conscious choice (of partners, desires, when to pair off and reproduce, etc.) or chimps and bonobos make conscious decisions too! Either way, the whole question of what a human life is, and who controls it, became way more complicated and interesting. Our human brains make decisions, maybe, but our behavior is also shaped by powerful biological urges—behaviors linked to the evolution of our bodies across millions of years, behaviors we share in many cases with other primates. As soon as the semester had ended he'd rushed to sign up for "Primate Anthropology" the next term. The instructor, as it happened, was Professor Phare's wife Kate Morgan (she hadn't changed her name when they married). An assistant professor in her early thirties, she'd be up for tenure in a couple of years. That class had been really interesting too, though not as electrifying as Professor Phare's. Kate—Professor Morgan, that is—had seemed kind of distracted and stressed out a lot of the time. So her lectures, while clear and informative, weren't always the liveliest. Still he appreciated her efforts. He liked the contrast between her demure appearance in class and the wild subjects she liked to talk about best. She was particularly keen on bonobo sexual behavior, dwelling at length on the way that bonobos used copulation, like humans, for a variety of reasons other than just brute reproduction. To relieve aggression and competition in a small group, for instance. And she loved talking about the way that bonobo females formed tight bonds in order to dominate the males, while the males got all kinds of sex out of the bargain. Sex with every female in the group on a regular basis! Including face-to-face genital sex, tongue kissing, even oral sex. They were interesting apes! It was kind of adorable the few times when Professor Morgan got excited about all this in class, not seeming to realize that the content of her lecture was so erotically charged, or that some of the students were shifting uncomfortably in their seats. She was a real looker too, though Chad tried hard not to think about it. He had so much respect for her husband. It felt wrong somehow. He'd looked at her ratemyprofessors.com page before signing up for the class, of course. Everyone seemed to like her as a teacher, but at first it didn't seem like anyone had much to say about her physical appearance, beyond a few tame comments that she was "attractive" and "pleasing to look at." She did have a chili pepper though. But on the last page of comments, back from when she had just arrived at UNC fresh out of grad school, there were a couple of juicier ones. "Those pant suits. Mmmmmmmm." "She seems kind of up tight in class. But I bet she's a real wildcat." "Nice lady. Nice body." Obviously he had looked her up on Facebook right away, feeling kind of bad about himself as he clicked on her profile. But there was nothing there other than a single picture, the same one as on her faculty webpage, a professional shot of her standing next to a podium in one of her dark pantsuits. He had to admit she looked good in it. Long auburn brown hair tied back in a tight bun . . . standard academic glasses . . . medium height . . . definitely fit . . . but with the outlines of some nice curves just visible beneath her conservative clothes (or was he imagining that?) . . . a little playful glimmer in her big brown eyes? . . . "a real wildcat." Chad's hand wandered down to his cock, just beginning to stiffen again, as he drifted off to sleep. Part 3 Kate Morgan couldn't get back to sleep. The couple next door seemed to be having the sex of their lives judging by the way the headboard of their bed kept pounding into the wall behind her, making her own mattress vibrate slightly. This was second time that night they'd gone at it like monkeys. There had been a break in the action for an hour or two around 2am, but now they were awake again, and the headboard was pounding louder than ever. They must have changed positions, she thought to herself mischievously, blushing a little, though no one was there. She wished her husband were there. But he'd left that morning for a worldwide lecture tour to promote his latest book. His new work on chimpanzee "apha males" and the so-called "violence gene" that ensured dominance was getting so much attention! She was happy for him, of course, but a little jealous all the same. It had been such a struggle for her to get any recognition at all for her own work on female bonding and mate selection among bonobos. And if she didn't get it published soon in a top journal she'd be at real risk of getting denied (and fired!) when she came up for tenure in a couple of years. She'd worked her whole life for this, and she couldn't bear the thought of falling short when she was so close to tasting success. Hopefully this research trip would yield some good results. Advanced Primatology Ch. 01 She didn't normally study chimps, but Brian had suggested the idea. Maybe if she could make some insightful comparisons between bonobos and chimps then her theory about female mate selection would get some more attention and respect. It seemed worth a shot. Most of her other ideas for summer fieldwork had failed to work out. So she agreed, more out of lack of better ideas about what to do with the summer then any real enthusiasm. But the timing of her trip, much to her surprise and pleasure, had turned out to be perfect! A couple of days before they were scheduled to leave Chapel Hill the head naturalist at the field station called up to say that the group's "alpha male" had suddenly vanished (no one knew where or why) and the group dynamic among the chimps was shifting in ways no one had ever seen before. She couldn't wait to get up there! This would be a golden opportunity to study the role the female chimps played in choosing a new dominant male (if there even were dominant males!). If her theory was correct, primatologists had for too longed focused on the big showy displays of aggression among competing males. Typical guys! Including her husband, though she loved and admired him. But Kate was convinced that the real decisions about who mated with whom, and when, and how often, were being made behind the scenes, among the women. Females, she had meant to say. Her mind raced thinking of the thousand little tasks she had to get done before the group set out by charter flight for the rain forest in two days. The stress alone would have been enough to keep her awake. But to make matters worse she was about to get her period, and for some reason (maybe the long plane trip?) she'd come down with an epic case of menstrual cramps. She really wished her husband were there. A good hard orgasm was always the surest remedy for her dreaded monthly cramps, and Brian was not at all squeamish about having sex with her while she was "on the rag." She hated that expression. So degrading. Why had she even thought of it? They'd been together for fifteen years, and they'd been married for eight, but they still had an active and fulfilling sex life, though maybe not as electrifying as when she'd first met him back at Berkeley. She'd been an eighteen-year-old undergraduate who idolized Jane Goodall and was hell-bent on becoming a world famous primatologist. A strange dream for a young woman, she realized. He was a twenty-five-year-old graduate student and her TA in "Introduction to Hominoid Psychology." They'd run into each other on the quad one summer afternoon after the class had ended. They were both staying on campus over the break to do lab work. He was on his way back from a pick-up soccer game and his sweaty t-shirt clung tightly to his hard body, revealing the shape of his chiseled chest and abs underneath. She was blushing like crazy as they chatted casually, Brian eyeing her up and down once or twice (she was sure she'd caught him) while praising her for her stellar performance in his lab section. His compliments about her schoolwork went straight to her heart, and the sight and scent of him went straight to her crotch. Within a couple of weeks they were dating and having great sex almost nightly. They had to keep things quiet around the anthropology department with her being an undergrad and all, barely legal even. But by Kate's junior year she'd moved in with him in his tiny apartment in Oakland. After all these years together he was still an attentive lover. He almost always got her off. Yeah, she really wished he were here. She reached a hand down into her panties, not even thinking about it really, and was surprised to find that she was dripping wet. She threw the sheets off, her frustration bubbling over, and realized that she'd taken off her shirt somehow earlier in the night, probably half asleep and tired of the oppressive humidity. It was a nice hotel but the air conditioners were on the blink. "Ugh, Chad, fuck me, ugh." The mattress vibrated a little harder as the headboard slammed into the wall. It felt like the sound was inside her head. She had a crashing migraine. Chad? Wasn't that the name of one of her students from "Primate Anthropology" last term? One of the bright ones who'd signed up for the trip? She couldn't put a name to the face but she was almost sure of it. O my God! Were those two of her students having sex in there? And which girl, she wondered? Young woman, she meant to say. Her eyes had adjusted by now to the moonlit room and when she looked down at herself she almost laughed out loud. The sight of her was too ridiculous. There she was, splayed out sweaty and nearly naked on a quaking mattress, with her hand down her panties as the couple next door continued to screw each other senseless. "Ugh, Chad, so big, ugh god, Chad." The headboard slammed so hard she thought it might break through the wall. Her own mattress began to rock rhythmically. "What are they doing in there?" she laughed to herself. Jesus, her own bed was shaking so hard it was almost like she was the one getting laid. If only! Her husband was probably asleep somewhere above the Pacific Ocean by now. She looked down and realized that her breasts were jiggling, quite a lot actually, keeping time with the frenzied thrusts of the couple next door. She wanted to pound her fist on the wall in frustration, but she was too embarrassed. What if she ran into them in the hall tomorrow and they realized it had been her? What if they were her students? She lay still for a while, fuming silently. And then suddenly, out of nowhere, the most absurd thought crossed her mind. What if she just went with it? What if she just fingered herself to orgasm right then and there, using the sounds and feel of the sex next door to help bring her over the edge? She did find them strangely arousing. And at least her cramps would go away then. No, it was too absurd. But once the thought crossed her mind, she couldn't get rid of it. It would be no different than taking some medicine, really. Wouldn't it? And maybe her headache would go away too. She closed her eyes and reached her hand down between her legs, her crotch soaking now, beginning to enjoy the feel of the rocking mattress as she fingered herself lightly, starting to get into it. She tried to picture Brian on the quad that day when they'd felt the first electric jolts of attraction, when they'd become mates for life. "Chad, fuck me, like that, like that." Their grunts and moans were just too distracting. "Ridiculous," she said to herself. "Ugh, Chad, so big, fuck me," she called out mockingly, but not loud enough that anyone might hear. She stood up and walked over to her computer, crazed with frustration. If she wasn't going to sleep at least she could get some work done. As she began sorting through old emails about the trip, and started to calm down a little, she thought how happy she was for Brian with all his professional success of late. He'd worked hard for a long time and he deserved it. But she was also kind of angry with him deep down. Maybe it was just the PMS talking, but she couldn't help feeling annoyed at him for not coming on the research trip with her. True it had been sweet of him to fly with her here and spent a long weekend with her on the beach and in the hotel bed. They'd made love six or seven times and it had been some of their best sex in years. And, yes, there were some vague plans for him to drop by the field station for a couple of days two weeks from now. He'd be doing a lecture in Rome and could swing through on his way to Tokyo maybe. "If we're lucky you'll be ovulating!" he'd half teased. But she didn't expect he'd really be able to visit in the end. Yeah, it was the pregnancy issue that had gotten her so worked up about everything. For years he'd been so eager to knock her up and start a family, and now that she had finally agreed, and gone off her birth control pills so they could start trying, he was off on a global lecture tour to soak up the acclaim of his fellow tenured scientists (most of them male, she couldn't help noting). Come to think of it, going off the pill was probably why her cramps were so bad now. It was also probably why their sex over the weekend had been so especially enjoyable. The hormone shift had apparently made the pleasure circuits in her brain go haywire. She'd loved every minute of it. And the thought of actually conceiving a baby gave their sex an extra illicit thrill. She still felt strange letting him cum inside her knowing they weren't using any kind of protection at all. It went against all the safe habits she'd instilled in herself as an ambitious career-minded young woman who most definitely did not want to be sidetracked by a baby, at least not until recently. She really had loved it. A couple of times, when she felt Brian's sperm shoot out hard against her cervix, she'd cum almost instantly. Long, mind-blowing orgasms as she dug her heels into his butt and clawed his back like some wild cat in heat. But Brian had loved it even more! He'd cum gallons inside her over the last 48 hours, just the thought of putting a baby in her belly making his testicles go into overdrive. She was pretty sure they weren't her fertile days, though. She hated all that stuff about charting your temperature on an ovulation calendar and inspecting your cervical mucus every morning to see if it was clear and stretchy, like an egg white. It felt so clinical, almost demeaning. Like her body was nothing more than a simple baby-making machine. The scientist in her knew that this was true in many respects. Her body had evolved to be able to procreate successfully. But she didn't like thinking of sex with her husband in those crude terms. So she didn't keep track her temperature. She was pretty sure she wouldn't have ovulated so close to her period though. Maybe she should look it up online? "Ugh, ugh, ugh, Chad, big." Well, Brian not being around for the trip was probably for the best anyway. She had grown to want a baby very badly over the last year or so, it was true, partly because it would make Brian so ridiculously happy, and partly because he'd been so relentlessly talking up the idea. But the timing was also extremely complicated with her tenure deadlines approaching. What if she actually did get pregnant now? "Oh yeah, Elise, just like that, yeah." "Oh god, Chad, oh fuck, yes." The headboard stopped pounding and Kate heard the sound of muffled laughter and soft voices through the wall. The festivities seemed to be over for now. Holy shit, thought Kate, suddenly realizing. That must be Elise Rice getting pounded in there. Was this "Chad" guy her steady boyfriend? He must be. Elise didn't seem at all like the type to hook up with a guy the first night she met him, let alone go all the way with him. Let alone twice. Kate shook her head and laughed. What did she know about it? She'd been with just Brian since she was a teenager. Chad . . . she really couldn't put a face to the name. Almost without realizing it she typed the name into the search box on her email account. Chad Berwick. Yes, that was him. She had an email from him asking her to excuse some absences from her class last semester due to travel for the soccer team. Another message confirmed that he'd be one of the undergraduate assistants on the Uganda trip. Chad Berwick . . . she was starting to remember him now. Before she knew it she had typed his name into google, and a split second letter she was clicking on the image results. Some action shots from the big UNC match against Duke last fall. He'd scored an important goal apparently and one quite nice photo showed him celebrating next to the corner flag, his arms spread wide with a huge boyish smile on his face and a look of sheer joy in his deep blue eyes. He was definitely cute. He was smart and polite, too, now that she remembered him. He'd come up to talk to her about some questions after class a couple of times, and she'd been struck by his respectful attitude and the careful attention he was obviously paying to her lectures. She felt like a snob for even thinking it, but she'd been surprised to find such brains and good manners in a kid from the Carolina foothills. So different than Pasadena, where she'd grown up. His accent gave him away instantly. Still, even with that black mark against him, she imagined that a lot of the nerdy girls like Elise would find him irresistible. Young women, she meant to say. God, what was going on with her tonight? Kate's hand was on her stomach now, playing with the dark hairs just above her panty line, as she idly scrolled through the search results. She really should go back to bed. She noticed the link for his Facebook profile. She clicked on it automatically. There weren't many photos, and most of them were fairly uninteresting. High school graduation and prom shots. He's definitely adorable, though, she had to admit. She should really go back to bed now that the noise had died down. Maybe she'd be able to relax enough to bring herself to orgasm and finally get some rest. She looked down and suddenly noticed where her hand was. Her nipples were rock hard. "God, Kate, you are so crazy when you menstruate." She stayed rooted in her chair, looking at the picture of Chad in his cheap rented tuxedo, with his goofy, oddly charming grin. I wonder if he got laid at his prom? I bet he did. What was that thing that her postdoc Karin had shown her how to do? That time when she was trying to make sure that they were no inappropriate pictures of her on Facebook—pictures that her friends had posted and tagged of her when she was younger that might undermine the professional image she worked so hard to maintain? Wasn't there some way you could search for tagged photos of a person that were accessible to everyone on Facebook? O yeah, now she remembered. It felt wrong, but what the hell. She was bored and angry and what else was she going to do at five o'clock in the morning, exhausted, alone in a hotel room? A couple of clicks and a whole new set of photos flashed up on the screen. These were much more interesting. Chad doing sit-ups and bench presses in the UNC gym surrounded by other sweaty young athletes. Chad shirtless at the beach in Hilton Head last summer with a group of scantily clad friends, both guys and girls. A full length portrait of Chad wrapped in a towel at his high school swim meet two years ago. O my god! Another one of Chad at a swim meet holding a big trophy this time, in nothing but a speedo, facing the camera with his boyish grin. "Is this even legal to be looking at," Kate laughed to herself? She'd never done anything like this before. He had just the kind of body she liked best, she caught herself thinking, blushing fiercely as soon as she realized. Long and lean like her husband's, but without the slight paunch of impending middle age. And it was hard to tell, but he looked like he was sporting a nice package too. Definitely in Brian's league. She really loved her husband's big penis. Nine inches hard, and a nice width. It wasn't that bigger ones could do anything different physically, she reasoned, though there was all that nonsense she'd read about "cervical orgasms" and such, but still, even so, there was something powerful about the idea of a big one, as if it gave her a different level of mental satisfaction. Not that she'd ever tried more than a few of them. She pictured the whole length of Brian's cock plunging into her and out of her as she lay back on the old bed in Berkeley, looking down the length of her body at it with rapt fascination, as Brian's tight abs kept working and working. Her fingers worked their way beneath her panties and down toward her crotch, almost with a mind of their own. Her pussy was on fire! She wasn't surprised at all to feel the wetness between her legs. She was drenched. "You've got to be kidding me," she gasped out loud, realizing that Chad was still smiling at her from the screen, with his tight body in nothing but a speedo. This was definitely her menstrual cycle messing with her. Getting her period always made her horny as hell, and it was worse without the pill. She remembered the title of that internet forum she'd read last month when Brian was out of town, after she'd masturbated three times in one night: "Why Do I Become a Walking Vagina when I Menstruate?" Why indeed? She realized she was still staring at Chad on her screen, appreciating the definition in his abs, the thin waist, the powerful hips. Jesus Christ, Kate!, she thought to herself. Was she actually getting off now on some picture of a cute kid from her lecture? This was crazy? Right? Even if there's no harm in it? (It's not like he would ever know). Even if it would make her cramps feel better and help her sleep? Even if he's got a chiseled body and a big bulge? Her pointer finger began tracing small circles on her clitoris. Her stomach muscles relaxed. It felt nice. "Uh uh. No. No way," she said aloud. She stood up quickly and walked toward the sliding doors that led to her patio. As she walked past the closet, she caught a glimpse of herself, naked except for her tiny panties, in the full-length mirror. "Not bad," she thought, satisfied with her toned body and full, womanly figure. It was no wonder that the boys left those degrading comments about her on ratemyprofessors.com. She'd tried to have them removed but they were still up there for the world to see. Would they count against her somehow for tenure? Women were always being treated unfairly about such things, as if their sex appeal was some kind of crime. Kate snapped up her t-shirt from the floor where she'd thrown it and put it on hurriedly as she strode out onto the patio. The sun was just coming up over the mild surf. The tide was all the way in. In two days she'd be in the rain forest. To be continued . . . Advanced Primatology Ch. 02 This is a story about what a professor and her students learn about sex, nature, and themselves on a research trip to study wild chimps. You can go back to the first chapter (probably better) or just start here. Chad is a soccer player from UNC who is an undergrad assistant on the trip, and is very good with the ladies. Kate is a professor at a crossroads in her life as she faces tenure and starting a family. ***** Part 1 Chad woke up to the sound of strange birds outside and the feel of a warm mouth around his shaft. Apparently Elise was a morning person. She'd already taken a shower and was kneeling on the bed between his legs in a grey push-up bra and matching underwear. "Good mooning, sleepyhead," she teased him. She looked straight at him as her tongue licked the whole ten inches of him, from base to bulbous head. Then she opened her mouth and lowered her face down slowly, taking as much of his thick shaft as she could manage. Chad watched for a while as she bobbed her head up and down, holding her hair back to get a better view. He could definitely get used to this. Elise paused, still holding the base of his shaft in her tiny hand, and looked up at him again quizzically. "So. Are you my boyfriend now?" she asked. "Do I look like him?" Elise looked down at his shaft and gave it a long stroke or two. "No. You don't," she replied, a playful glint in her eyes. Then she put him back in her mouth. Yeah, this was going to be an interesting four weeks. Part 2 "This is not about sex," Kate told herself, "it's about work." If she didn't have at least one solid orgasm this morning she'd have cramps and a headache all day. And she needed to be sharp for the official first day of the research trip. Dealing with all the logistical hassles, not to mention the raging hormones of nine undergrads, not to mention her own, was going to be quite a task. And she'd only gotten a few hours of sleep last night at most. She thought of the sounds coming through the wall last night as Chad and Elise pounded their headboard against her wall. She thought of how crazy she'd been acting since she started menstruating this time, now that she wasn't on the pill anymore and she and Brian were trying to make a baby. She was glad Karin, her postdoc, and her new graduate student Jessica were there to help keep the younger ones on task. There was so much riding on this trip for her. She'd realized in the shower. What she needed to do now was to get herself off quickly, then get dressed and head down to breakfast before the first orientation session at 9 am sharp. She but on a bathrobe and strode decisively over to the little desk where she'd set up her laptop. Lucky thing Brian had texted her this morning about the spare flash drive he'd left behind. And lucky she'd remembered the small stash of porn he kept on it for when he was travelling or when she was out of town. She didn't begrudge him this little "vice." He had needs like every other guy, or woman, and masturbating to a video now and then was better than anything else he could do to meet them when she wasn't around. She knew he had loads of opportunities to hook up with his colleagues and "groupies" while he was travelling, or with the female students in his lab when she was away giving a talk somewhere, and she appreciated the way he kept such clear boundaries with all of that. And she didn't mind, really, that most of the videos he liked best were about older authority figures hooking up with younger people in inappropriate ways. She understood the illicit appeal. There had been an age difference between them when they met. Still was one, she reflected. And not that it really mattered, but technically he was still kind of in a position of authority over her. She didn't have tenure, after all, and he did. So she understood why he was drawn to videos like the one she was opening now as she untied her bathrobe and let it fall away from her, her legs spreading wide as she eased back in the desk chair. She'd watched this scene with him late one night when neither of them could sleep and they needed a little inspiration to get their juices flowing. It had worked like a charm. They'd had great sex afterwards. A little bit corny, she had to admit. It was from a video called "Sex Teacher" that had a bunch of other vignettes that were pretty good too. She'd watched them all one night, the night she'd masturbated three times. Brian was out of town and he'd forgotten the flash-drive again. She loved all those boyish traits he still had. In this one an older male professor type (or was it high school?) was talking in his office with a skinny blonde girl with a short pony-tail. She was chewing gum and asking questions about her paper and the grade, Kate supposed. She hadn't been able to find her headphones and didn't have time to look for them any more. The older guy was leaning back in his desk chair with his hands behind his head as he appraised the girl coolly. Kate's hands went to her breasts and began to knead them hard. The girl's expression changed. She seemed to be saying something more flirtatious, dirtier. Kate flicked her nipples as the older guy leaned forward and smiled. Then the girl walked around to the side of the desk and took the gum out of her mouth. Kate's right hand went to her crotch as she continued to massage her breasts. "This is not about sex," she reminded herself. She had things to do and places to be. She reached out with her right hand and scanned forward a little in the scene. Now the girl was on her knees with her tongue sticking out and the professor's cock in her tiny hand as she stroked it roughly, licking the head once or twice. Kate's hand went back to her crotch, taking some of the wetness from inside her and spreading it on her labia and clit. It was hard now and she traced a few slow circles around it with her finger. She leaned back further in the chair as the girl took the whole length of the professor in her mouth, gazing up at him with her devilish blue eyes. She scanned a little further and she was still on her knees with her smallish breasts wrapped around the professor's dick as he thrusted up between them. Further and the girl was bent over the desk with her bottom half exposed. The professor stood behind her, naked with his hands on his hips. Kate liked watching his butt muscles contract as he pounded into the girl. He looked kind of like Brian, but beefier and with more of a gut. Kate was making faster circles on her clit now and raising her butt off the chair as she leaned back to get the right angle. She scanned to the end of the scene. The girl was on her knees again and the professor was cumming now on her smallish breasts as she held them up to him with her hands. A few more quick circles and Kate felt the orgasm wash over her. She sat back in the chair a minute and stared idly at the screen. Before she realized what has happening the next scene had already started. This one showed pretty much the same situation but with the professor as an older brunette woman and the student as a skinny blonde guy with an earring. She scanned through it quickly. He was telling her something with an "aw shucks" expression and a look of embarrassment on his face. She was listening sympathetically with her big brown eyes and nodding her head as her hand reached across the desk toward him. Then he came around the desk and stood in front of her with his pants down while she stroked and blew him, still seated. Then she put him on his back on the desk and mounted him, still wearing her skirt and bra, but with the cups pulled down to display her large breasts. That scene was good too, she remembered, but she'd have to save it for later. Still, it was tempting to get herself off again, just one more time to make sure the cramps went away, even if she risked being late. No. She better not. She walked over to the closet, throwing her bathrobe to the floor, and paused for a minute in front of the full-length mirror. She really did have a terrific body. For any age, let alone thirty-four. The woman in the video couldn't hold a candle to her, though she guessed they were supposed to be the same "type." They both wore "serious" glasses over their round, brown eyes and had darkish hair that parted in the middle and hung down to just below their shoulders. They were both the same age and in exceptional shape (Kate was religious about her yoga and running) but still with womanly figures. Big round hips and generous butts, firm and heart-shaped. Kate turned around and stuck her butt out a little to inspect it. "Nice lady, Nice body" she laughed to herself. Then she wrinkled her nose as she remembered where that comment had come from originally. Of all the comments on ratemyprofessors.com Brian loved to tease her about that one the most (though he also liked the pantsuit and wildcat comments). He was always repeating it to her around the house while he groped her breasts from behind or weighed her ass in his hands. She didn't mind too much, though she still found the comment an offensive one from a student, and wanted it removed from the website. But it was important to their marriage to keep a little edge in their sex life. Kate turned around and appraised her front side. The woman in the video definitely had much bigger breasts, though like Kate's they were appealingly natural. Large and heavy but with a great shape. They felt firm in your hands. Kate reached up and cupped her breasts from underneath, bouncing them a little to make sure. Then she opened the chest of drawers beside her and took out a bra, a simple black number that she usually wore under her teaching clothes. She reached behind her to clasp it. Jesus, she could hardly get it shut. Her breasts were definitely bigger when she menstruated, though still not nearly as big as the woman's in the video. There was no way she could disguise hers under a pantsuit jacket. When she finally got the clasp shut Kate looked up into the mirror again, and, without even thinking about it, pulled the cups down from her breasts and tucked the fabric under them, the added support making her breasts stick up a little higher. Not bad, she thought. She'd have to keep that trick in mind for Brian's next visit. She stuck her chest out and smiled flirtatiously like the woman professor in the video had to the skinny blonde guy. She had a crazy idea to go find her glasses and complete the look, just to see the effect it created. But she didn't have time. She rearranged her breasts and opened another drawer to find a shirt. Her first idea was the cute purple scoop-neck she'd worn out to dinner with Brian a couple of nights ago. It was casual, and would keep her as cool as possible. But would it be too tight now that her period was about to start? She pulled it over her head and inspected the results in the mirror. No way, she laughed. Her breasts were way too big today for this one. They looked like they were about to burst through the stretchy purple fabric. She was even showing a little cleavage. She put on a loose white blouse instead (damn, she was late already) and reached for her usual black pants, the kind that went with her pantsuits. She had a lot of things to get together before she went down to breakfast and she needed to get moving. Part 3 Kate strode confidently through the hotel restaurant where Karin, Jessica, and most of the undergrads were already eating. At least she tried to seem confident. On the elevator down she'd realized that her blouse wasn't quite as unrevealing as she'd thought at first. Her breasts were definitely straining against the white fabric a little and it looked like a couple of the buttons were pulling apart. She hoped no one could see her bra, or worse her breasts, through the small gaps opening between the buttons. Her pants felt tight on her bottom too, and on her crotch. She wished she'd brought her jacket with her, even if it would be uncomfortable in the heat. But it was too late to go back upstairs now. She took a deep breath and kept her eyes fixed on the center table where Karin and Jessica were already seated, chatting over coffee. She felt the eyes of the undergads inspecting her as she strode through the room, trying not to bounce too much in her simple flat-soled shoes. Not all of the kids were up yet, she noticed, but Chad and Elise were sitting at a table with another girl (Courtney?) and some guy she didn't know. Well, it was natural enough if they looked at her. She was the group leader after all. The alpha. "Good morning," she said to Karin and Jessica, throwing her briefcase hurriedly on the table and heading off to the buffet to get some coffee and something to eat. She felt the undergrads looking at her again, especially the guys, as she picked up a plate and tried to decide what to eat. She had her back to them. She knew she had a nice butt. She was always catching guys staring at it. And today it was popping out a little extra in her suddenly too tight slacks. It felt humiliating and strangely alluring all at the same time, she thought, as she poured herself some coffee. Jesus, maybe she should have masturbated a second time before she came downstairs. She needed a clear head today. Kate strode back to the table trying not to be too bouncy again and sat down between Karin and Jessica. "Sorry I'm a little late. I didn't sleep well last night." "Missing Brian?" Jessica asked, with a playful expression. Kate wrinkled her nose at her, vaguely disapproving. Jessica was a talented young Ph.D. student. She had loads of potential. But she also had a habit of stepping over the kinds of professional boundaries you needed to respect if you were going to be a successful academic, especially if you were a woman. "Well, yes, I guess I am." Jessica laughed. Karin shot a look at Kate and rolled her eyes. They'd talked about Jess a number of times. They made small talk about the flight and their rooms and the trip ahead of them while Kate pushed her food around her plate with the fork. Her cramps were gone for now but she still didn't feel very hungry. She pushed her plate away from her and leaned back in her chair, sighing. Jess and Karin eyed each other significantly. They were both thinking the same thing. Was she feeling nauseous? Maybe even morning sickness? Or just a bad case of the cramps? Kate could tell what they were thinking and resented the feeling of being scrutinized. Like some ape in heat. "What?" she snapped, her temper getting the best of her. Jess and Karin looked at each other. They'd both seen this kind of thing before. "Nothing," smiled Karin, the older and more polished of the two young scientists. "Not feeling well or something?" "No, not especially," Kate smiled back at her, recovering her composure. Suddenly she felt the urge to confide in the two young women, her only two adult companions for the four weeks in the rain forest. They were female like her, after all, and they'd have to work together smoothly if the research trip was going to be a success. She'd have to become more friendly with them. And it would be nice to have some friends to talk with these days, when she was so stressed out and conflicted with all this intense stuff happening about her tenure and trying to get pregnant. "Sorry I'm such a bitch this morning." The younger women nodded. "It's just that I have an epic case of menstrual cramps," she continued. It felt good to talk and once she started she couldn't stop. Before she knew it she was saying too much. "They started last night and kept me up and I have a headache too and my cramps are always pretty bad but this time they're horrible because I went off the pill a couple months ago and my hormones are still crazy." Jess and Kate laughed. She could see the wheels turning in their heads. "Wait, you went off the pill?" Jess asked, suddenly connecting the dots, "O my god, are you and Brian trying for a baby?" Kate nodded and both the younger women gave her big, excited smiles. They were really very nice. She felt good around them. "I know how it is," said Karin. Jess and Kate gawked at her. "Not about getting pregnant!," she clarified, "about going off the pill. You feel like a madwoman at first but then once your hormones balance out it's much better. I totally prefer it now that I'm off it too. It's much better to follow your natural cycle. You know that you don't ovulate when you're on the pill, right?" Kate nodded. "It feels better when you get that back," Karin continued. "You feel so powerful and energized on your fertile days," her eyes flashed as she said it. "I've really noticed the difference since I stopped the pill." "Yeah, and you feel so horny too!" Jess gushed. "When I went off it I could barely keep my legs together. My poor boyfriend! Not only did he have to wear a condom but he actually got an injury from all the sex we were having! Too bad for me. Lab sessions were torture with all those cute boys ogling me all the time. You know they loved that lab coat! Sometimes I'd tease them a little at the end of class." She pretended to take her coat off for them, closing her eyes and sticking out her breasts, wiggling them a little, as she pulled it from her shoulders. "Jess, please!," cried Karin, looking around at the undergrads nearby, though she was laughing a little too. Kate clearly disapproved. She wrinkled her nose at Jess and turned her attention to some papers in front of her. Jess really was a beautiful girl. An olive-skinned stunner from Argentina, who dressed the part, Kate noted, and had a shapely pair of b-cups. Kate kind of envied them this morning, with her own breasts feeling so swollen and out there in the open. Jess wouldn't have any trouble concealing hers, if she ever tried. Kate surveyed Jess's outfit wondering if it were professional enough for an instructor. She was wearing a neat maroon v-neck top, sleeveless. Kate glanced under the table quickly and noted the olive skirt that showed a lot of Jess's legs. I don't know, Kate thought. It's right on the edge. She might even have to say something about it. She didn't mind the views of Jess's strong arms and legs, toned from all the cross-fit she did (all the new grad students were into that). Why not show that off! But her chest and rear-end! The v-neck was cut a little too low and Jess was a wearing a pushup bra that made her breasts point upward slightly, their full outline visible beneath the stretchy fabric. It wasn't obscene or anything but it was definitely too tight for Kate's taste. She wondered if the skirt was too. Had she gotten too prudish about these things in her mid-thirties, she wondered? She looked at Karin's outfit and was struck by how much it revealed too. She was also a very beautiful woman. Almost a younger version of Kate, she thought, with unconscious pride and maybe even a flash of jealousy. But she was darker, like a lot of Jewish girls, and with curly hair, longer and browner than Kate's, almost black. Karin had returned to the buffet table and Kate watched her butt stick out a little as she leaned over with her plate to grab some food. She had a large but firm butt like Kate's and was wearing some fairly short blue tennis shorts that complimented the shape of it and showed off her long tennis player legs. She'd played at Duke, where she'd met her fiancé, a psychology professor, who'd pursued Karin when she was a student, just out of high school. Karin was walking back to the table now and Kate admired her full hips in the shorts, which were revealing but kind of sporty in a way that made them seem more appropriate somehow. The shirt was the same way, a tight navy tank-top that showed off Karin's substantial, but shapely chest, a little smaller than Kate's, but definitely in the ballpark. She was a sexy young woman, you couldn't deny, but the outfit managed to present her more as a confident professional with important things to do and the energy and focus to get them done. Her whole body language said plainly that she wouldn't waste time worrying if her students enjoyed the view. If she felt comfortable and confident and it helped her do her work then that was what she'd wear! Advanced Primatology Ch. 02 Kate looked up from her notes and realized that Jess and Karin were still talking. "I should get a diaphragm too," Jess was saying, "That sounds so much better! I'm sick to death of condoms, and the boyfriend is too." She lowered her voice, "We've done it without one a couple times, and it felt so hot it scared me a little." "Jess stop," Karin said and looked around her again. For some reason it didn't feel awkward to discuss these intimate details with her colleagues. They were scientists after all, and all of them had a strong interest in the subject of female sexuality among primates, including the human ones. The subject of sex and reproduction led naturally to the work ahead of them. They were all agreed on the main research objective of the trip, but they reviewed it anyway because they needed to communicate it to the undergrads if they were going to be effective assistants. They were out to disprove what had become the leading theory explaining the role female chimps played in the process of mate selection within small groups, a theory that was understood to describe most primates, and that was now being applied to explain female sexual behavior in humans. In a nutshell, the theory held that male chimps competed among themselves to attract the best females, the ones with the best genes, the ones with the brains and brawn to ensure the survival of their young and give the males the best chance of passing their genes along to a dominant offspring. They did this in many ways, but the most important one to emphasize with the students today was the display of penis size. Like with humans, male chimps had been sexually selected to have long penises, about 8cm compared to the 3cm of a gorilla or the 13cm of a human. Kate thought of her husband's 9-incher appreciatively. Research showed that the males who were able to mate the most often with choicest females at their peak fertility (advertised through the swelling of their sex organs) tended to be the ones with the longest penises, which they displayed to the females when they sensed they were in heat. As the females approached (chimps were promiscuous rather than monogamous) conflicts would break out and the males would challenge each other. The leading theory, which Brian's work on the "violence gene" was a big part of, was that these physical contests between the males, and the strength and aggression displayed in them, determined everything about mate selection. He'd just published a book showing that the most successful males in terms of frequency and timing of sex with the highest-ranking females were also the ones that showed the most extreme tendencies toward violence, severely wounding their male challengers, sometimes murdering them outright, sometimes beating the females to keep the group in line. Brian had even proposed that it wasn't much different with humans. Some of his new research traced women's preferences for different kinds of sexual partners at different points in their menstrual cycle, showing that on their fertile days, when they were ovulating, women were far more attracted to the aggressive, dominant types than at any other point in their cycle. It even showed that women in long-term relationships with "nice guys," the nurturing types who seemed likely to be good dad's, were actually even more attracted to the dominant types when they were fertile than girls who weren't in relationships at all, and that they reported feeling more likely to cheat with alphas as well on those days. Brian proposed that this was because human females, not unlike some other primates, were trying to have their cake and eat it too. They wanted the dominant genes of the alphas to pass along to their own offspring, but they wanted them on the sly. That way they could be sure that the "good dad" type would stick around to raise the baby, thinking it was his. He even suggested that women had evolved to conceal their ovulation from "nice guy" types, who lacked the heightened senses necessary to detect it, while also subtly advertising their fertility to any alphas in the area. But Kate had been collecting some information that showed something different, that among chimps, not unlike her beloved bonobos, it was the small clique of females at the center of the social group that were actually in charge. They maintained tight bonds between each other through grooming and sharing food (though not typically like the bonobos by rubbing their crotches together or tongue kissing). And they showed clearly to the rest of the group, through their body language and complex vocalizations, that it was they made the most important decisions: about who ate what, and in which order, about who slept where, about which males would be given the best chances to reproduce with them. When they'd reviewed their main goal they turned to more practical problems. It was going to be tough keeping the undergrads in check and developing a clear chain of command for their work in the field. They had to set some clear ground rules and establish a system for who was going to monitor and enforce them. None of the women wanted to be in charge of this because they were all too focused on the chimps to want to worry about the students. The undergrads were just tools to help them meet their primary objective. Karin had a good idea. "What if we appoint one of the students as undergrad leader. She could be the bad cop to make sure the other kids are doing their jobs." "Good idea," Kate replied immediately. "But who?" asked Jess. "What about Elise," Karin proposed. "She's smart and a hard worker. She really impressed me in Brian's class last term. She struggled at first but she kept coming to my office hours, Brian's too, and she improved dramatically. She got one of the few A's in the class!" Kate didn't like Elise much for some reason, she wasn't sure why, but she didn't have time to worry about the details on this one. "Good," she declared, "Elise it is. Anything else before the first session?" Jess spoke up this time. "Well, maybe we should make one of the guys an undergrad leader too," she said, rolling her eyes playfully. "I mean there's only three of them, and I don't think they could cause much trouble with a rebellion or something. But if they have to follow orders from four females the whole month their brains might explode!" Everyone laughed. "Okay," said Kate, "which one?" "What about Chad," Jess said, in a dreamy voice, doing a pretty good imitation of the way one of the undergrad girls would have said it. They laughed again. Kate suddenly realized she'd been watching Chad's table out of the corner of her eye every once in a while. A third girl had joined them now. A cute redhead named Ellen. And now all three girls were sitting as close to Chad as they could get and leaning toward him a little as they hung on his every word and smile, laughing at his jokes. The other guy at the table, poor thing, seemed kind of sulky about it. "I don't know," Kate replied. "No, I think he'd be very good," Jess continued, more seriously now. "I was his TA in your class remember, and he did very well. We gave him an A." All three women turned their heads to watch Chad as he stood up and sauntered to the buffet table to refill his plate. He looked good in his grey "UNC Soccer" t-shirt and long shorts, snug around his waist and butt. He was still smiling from something he'd said to the girls at his table and he walked slowly and deliberately, strutting almost. "I don't know," Kate said again. "He doesn't seem right." "I agree," declared Karin. "Way too cocky." "I know what you mean," Jess sighed teasingly. "Muy caliente!." "That's not what I meant" Karin scolded her, only half serious. "He's barely legal for christ's sake." "So?" asked Jess. "We're not so uptight about that stuff in Argentina." Karin laughed but Kate wrinkled her nose again. She was going to need to have a talk with Jess about respecting boundaries. "And if you think he looks good in those shorts," Jess continued, "then check out his Facebook page. That's all I'm going to say." Karin smiled knowingly, blushing a little, while Kate pretended to be confused. She hoped her cheeks weren't red too. There was an awkward silence for a few seconds. "Look," Jess went on, "all I'm saying is that he looks like he'd do a good job keeping the other two guys in line. And if last night is any indication I think that he and Elise would work pretty well together." She smiled playfully again. The other women tried to play dumb, but Jess kept probing and before long they'd all admitted to hearing them. It turned out that all of their rooms shared a wall or floor with the one Chad and Elise had slept in. Jessica's was below it, and Karin had the room on the other side of it from Kate's, the one without the headboard. Karin and Jessica continued to chat as Kate's thoughts drifted back to last night and she felt a cramp rise in her stomach. Damn, maybe she really should have masturbated a second time. She looked over at Chad's table and this time his body language was different. Ellen was talking and he was sitting up straight and smiling and nodding with an expression that showed he was listening to her carefully. He did seem wrong for the part in some ways, but the more she thought about it, and watched him, the more it made sense. He certainly looked the part, especially in that speedo, she thought to herself archly. But more importantly he had the qualities to be a good leader for the younger ones: disciplined, hard-working smart, and most of all, respectful of authority. Of female authority, she noted. She'd gotten a strong sense of that when they'd talked after class a couple times. There wasn't the slightest frat boy vibe from him at all, and she liked to think she was a pretty good judge of character. "Agreed," she declared. "Chad it is." The women stood up and headed out to their first session with the students. Part 4 After a long day of orientation sessions this was the last place she wanted to be. But it was important that she make her presence felt at the evening reception she'd scheduled for the end of the first day of work. She noted with disapproval that some of the kids, and even Jess and Karin, were drinking. Was that even legal here for the undergrads? Kate stood near the center of the room with Karin and Jess, making small talk about the day's sessions and complimenting each other about how they'd handled themselves today. They were turning out to be a great team. Kate liked them and was looking forward to spending more down time with them like this, cutting loose a little bit. But tonight she just wanted to get to bed, especially now that the some of the undergrads were a little drunk and had started getting louder and rowdier. She appraised the other two guys on the trip (besides Chad) as one punched the other in the shoulder and they doubled over laughing. She thought they'd been saying something about Elise, judging from where their eyes had been, looking straight at her butt as she started to sway a little on the dance floor and the hem of her cute little sundress rose up. Jess offered to get her a drink. "Sure," Kate replied. She'd stay for one drink and then head up to bed. Ten minutes later as the women continued to chat she noticed that Chad was walking straight toward them. When he was a few feet away he stopped suddenly and surveyed the group cautiously, almost shyly, unsure of what to do next. Jess noticed him first. "Hi Chad!," she said excitedly, making big, bright eyes. "Hi Professor Aguero," he answered with a friendly smile. "Call me Jess, silly, I'm not a real professor. Yet." Karin shot a look at Kate and rolled her eyes. "Okay, Hi Jessica," Chad said, a little flustered. He was very cute. "Hi Professor Stern," he said, turning to face Karin. "I guess I'm not a professor either, technically," she replied with a little edge in her voice. "You can call me Karin." "Hi Karin," he replied, smiling again, but with more formality this time, more respect. He turned to face Kate. "Hello Professor Morgan." "Hello Chad," she replied, smiling warmly. "I'm so glad the summer scholarship came through so that you could be here after all." Chad blushed a little and stole quick glances at Karin and Jessica to see how they'd reacted. Kate felt awful. She could tell he was very sensitive about being a scholarship kid from the foothills. They all stood there for a few seconds awkwardly. "Thanks. Me too," Chad replied, trying to recover his poise. He shifted his feet for another second or two. He really was adorable. He'd changed into something nicer for the reception and he looked charming and handsome in his short-sleeved collared shirt (linen, and blue like his eyes) and a pair of pressed khakis. None of the other kids had dressed up and Kate found the gesture touching. "Well, anyhow," Chad continued, bowing his head slightly as he turned toward Kate again. "I just wanted to thank you for making me undergrad team leader. I really appreciate it. I'll definitely do my best to repay your confidence in me." "You're very welcome, Chad. I'm sure you will," Kate replied, again smiling. "Don't thank us," Jessica jumped in, making bright eyes at Chad. "You earned it." She poked him in the ribs as she said it. Chad took a half step backwards in surprise, grinning awkwardly. "You should have heard me telling Kate—sorry, Professor Morgan—about all the hard work you did in my lab section last semester. You were fantastic!" Had Kate imagined it, or had Jessica put an added emphasis on the word hard as she'd spoken it, stealing a quick look at Chad's crotch as she reached forward to poke him? And was her menstrual cycle playing tricks on her again, or had Chad returned the favor, scanning Jessica up and down coolly, just once, almost too quick to see, before he remembered where he was, and who he was talking to, and turned to face Kate again. "Thanks. It means a lot me. Have a great night!" He turned and walked toward the dance floor where a few of the undergrads were beginning to gather. Kate couldn't help laughing a little as he walked straight up to Ellen, smiled flirtatiously, and shook his hips a little, grabbing her hands and pulling her away from the group, where they had more room to move. She noticed Jessica and Karin watching too. "Well, he's a charmer," Karin noted drily. Jess nodded absent-mindedly. "Well, I think it's time for me to have one more drink," Jess declared, then turned and strode toward the bar near where the undergrads had all started dancing now. "Uh-oh. Trouble," said Karin. "What?" Kate asked, pretending not to have noticed. "You really have been out of the game for a long time. You didn't feel the sparks between those two? I was afraid my cheeks would turn red." "No, not really," Kate replied. Karin raised her eyebrows and shook her head. They stood there for a few seconds watching the students. Karin started moving her shoulders a little in time to the music, loosening her neck and staring vaguely in Chad and Ellen's direction, Kate couldn't be sure. She felt tired and lonely all of a sudden. "Big day tomorrow," she declared finally, "I'm going up to my room to try and have an early night." "Me too," said Karin, after pausing a second or two to consider. She placed her drink down on the nearest table. The two women turned their backs to the students and headed for the elevator. Part 5 Around midnight Chad and Elise stumbled drunk into his bedroom and started ripping each other's clothes off. They were horny as hell. The sexual tension caused by Chad's flirting with Ellen had really gotten Elise worked up, which had been his plan all along, and Chad was beyond excited by Jessica's moves on the dance floor. But they were tired and had a long day tomorrow so they wanted to hurry. Within seconds they were on the bed in their favorite position—Elise on all fours with Chad behind her. Her pussy felt great and her tight litle ass was a sight to behold but Chad couldn't get Jessica out of his head. Not that he wanted to. How was it possible that he'd never noticed her before? Olive-skinned Latina. Great body. He'd definitely gotten a little vibe from her, first when he was chatting with her in a circle with Karin and Professor Morgan, and then a little stronger when she came out on the dance floor for a song or two before she headed up to bed. He'd watched her carefully. There was nothing particularly salacious about her moves, though she looked really fine doing them. All three of the undergrad guys, including Chad, had gravitated toward her on the dance floor. They were practically surrounding her as she let herself go a little and enjoyed the music. Still, he wasn't picking up much. But then, just for a split second, she'd turned toward him and flashed a heart-melting smile, maybe a little too playful, while she swayed her hips. Then she turned around and stuck her ass out at him while she shook it a little. Chad had laughed. It was like his body gave off a gravitational force that drew female sex organs toward him. He had to turn around and un-tuck his shirt to hide his hard-on. It hadn't been like she had one of those flashing signs over her head ("Available to Mount") that he was used to seeing when he pursued undergrad girls, like Ellen had had tonight. But there were some signals for sure. It was no accident that today was the first time he'd noticed her tits and ass, and no accident that he was fantasizing about them now as he fucked Elise a little harder and rubbed her anus with his thumb, feeling his pleasure mount. Intentionally or not, Jessica had done something to make him notice her physical charms, had displayed her body to him to let him know she was receptive. It was not totally unlike the female chimps in estrus he'd learned about from Professor Phare. He remembered his lecture about the way the females advertise their fertility through an obvious swelling of the genitals, among other signs, and his theory that human females had never lost these traits completely. They did pretty much the same thing, though scientists normally thought of them as having evolved "concealed ovulation" as a more effective mating strategy. That was part of the story, sure, but if you thought about in a different light, Professor Phare insisted, you started to see all kinds of subtle ways that female humans still proclaimed when they were fertile and willing. Through engorged breasts and clitoris, changes in scent, body language, and the sound of their voice. There were a bunch of recent studies showing that women were more likely to wear eye-catching colors like red and pink when they were ovulating, and that on those days they were attracted to more dominant guys, even if they were in a relationship (actually, even more strongly if they were in a relationship with a nice guy, a provider type). It was as if on those days their primate brains took over and they started hunting for the most successful male genes around, looking for things like stronger odors, square jaws, deeper voices, more aggressive behavior. Jessica had been wearing maroon today, he noted. He remembered Professor Phare's suggestion that "alpha males" possessed a kind of sixth sense that let them pick up on such signals when other males couldn't. Karin and Kate had looked great too. Particularly Kate—Professor Morgan he corrected himself. He'd definitely gotten a better sense of her figure in that white blouse, without her customary jacket. He was pretty sure that she had some fantastic tits under there, some of the best large ones he'd ever seen in person. She reminded him of a porn actress in some video he liked. He didn't watch porn much. Didn't have time to. But like any guy he kept a steady supply of it on hand for when he needed it, mostly during the weeknights when he was too tired from working out and studying to want to go out and party, or even to text one of the girls he was fucking that month. Advanced Primatology Ch. 02 The video was a little twisted. It starred a brunette step-mom who was pretty much the same type as Professor Morgan (though not half as pretty) and some buff teenaged dude. She comes into his room in the morning in her office clothes and glasses, her tits practically bursting out her blouse, and is pissed to find him still asleep in bed. So she rips the blankets off and is shocked to see that he's naked and sporting a huge woodie, about the same length and width as Chad's, he noted proudly. Before you knew it she was straddling him on the bed, still wearing her glasses, with her shirt unbuttoned and her tits popping out of the tops of her black bra. And then the shirt was off, but the glasses were not, and she was reaching behind her to unclasp the bra, her womanly breasts spilling out. They were a little bit bigger than he would have liked but it didn't spoil the effect. A little bit bigger than Kate's—Professor Morgan's—he suspected. The headboard was slamming into the wall so hard now he was afraid he might put a hole in it. Elise was grunting the same thing over and over. "So big, so hard" He remembered that during lunch break he'd come upstairs to recharge his phone and noticed Professor Morgan coming out of the room next door. The one behind the wall he was pounding the headboard into. He wondered if she could hear what was going on in his room, and he started pounding harder, as if he was trying to fill the whole hotel, if he could, with the sounds of him dominating Elise and making her cum hard and long around his shaft. Maybe Kate was even enjoying this. God what a hot idea! "So big, so hard." Chad thought about what Professor Phare had taught him about "copulatory calls" (or mating calls) in groups of primates. The way that female chimps tended to be much louder when they were mating with dominant, high status males, and the way that male orangutans made long calls to attract nearby females. "Ugh, ugh, ugh, ugh." Before he knew it Chad was grunting loudly and fucking Elise like a madman. After just a minute or two of Chad's primal grunting Elise's pussy exploded. He loved the feel of her tight, wet canal as it began to spasm uncontrollably around his stiff cock, sending Elise into the most intense orgasm she'd ever had and bringing Chad right up to the edge. In a flash, and without any conscious thought on his part, he was imagining that it was Professor Morgan on her knees in front of him ("Those pant suits. Mmmmmm"). The pressure kept building in his testicles. "Ugh, ahhh, ugh, ugh." And then he was picturing Kate in the same position as the step-mom in the video, her soft tits spilling forward as she reached back to unclasp her bra, straddling him with her strong legs. And then his balls contracted and he started cumming hard inside Elise, inside the condom that is, as deep as he could go. And then he kept on cumming, for what seemed like a full minute (holy shit there was a lot of it!) maybe harder and deeper than he had ever cum before. He thought he might have broken the condom. But when he finally pulled his cock out the rubber was still in tact (probably a good thing) the tip filled with a wad of sperm the size of a golf ball. Later that night, just before dawn maybe, he woke up alone in the bed. There was a note on the night table. Elise hadn't been able to sleep and had gone back to her room to send some emails and things. He didn't mind, even though he was still a little horny. Suddenly he remembered something that he'd wanted to do on-line in private and that he might not have another chance to do before they left for the mountains, where there would be limited internet access for the undergrads. They weren't even allowed to bring their laptops. Having sex would be more complicated too. The guys would all be sleeping in one bunkhouse, and the undergrad girls in another. He wasn't sure where the women would be sleeping. Chad stood up and walked over the to the little desk by the patio window where he'd left his laptop. He thought about earlier. It was crazy how much he'd cum when he fantasized about Professor Morgan while he fucked Elise from behind. She definitely was his type physically, he had to admit. He'd always been a sucker for a big soft pair and a wide set of hips. He didn't feel too bad about getting off to her because it was obviously nothing more than a fantasy. He had never seen her give off even the slightest vibe of being on the hunt for new sexual partners, or even available for pursuit by players such as him, not even when she lectured about the wild sexual exploits of her beloved bonobos. But there had been that "wildcat" comment on ratemyprofessors.com. Maybe some of her male students had picked up on some subliminal signals that he wasn't seeing. Not likely. Anyway, even if he did pick up on them he would never do anything about it. Her husband was one of the nicest grown-ups he'd ever met, and Chad was hoping to get a letter of recommendation from him when he applied to grad school, maybe even be part of his lab. And now Professor Morgan was turning out to be a great mentor too. He'd really been touched by her confidence in him when she agreed to make him undergrad team leader. He was determined to do his best for her. Chad opened his laptop and did some casual google searching for Jessica Aguero. He went straight to her Facebook page and in no time at all had pulled up a couple spectacular bikini shots of her on the beach in Argentina in one of the tiniest suits he'd ever seen. There were no shots of her from the rear, alas, but there was one from the side that showed off the full form of her magnificent ass. Latina chicks were always dependable that way. "Nice," he said out loud to himself. That was definitely a thong she was wearing. He looked down and noticed that his cock was stirring to life, half hard now and beginning to lift itself off the desk chair where it had been resting flaccid. He hadn't put any clothes on when he got out of bed. Yeah, Jessica was definitely his next priority target. He'd sensed that she was pretty good friends with Karin, so maybe if he could work out way to talk with the two of them alone sometime he could try to flirt with Karin a little and set his standard plan in motion. He wasn't sure. Would he get in trouble for that? He'd have to be careful and think it through. He was pretty sure that these older chicks weren't much different from the undergrads he normally chased. They had the same biology and brain structure after all. But he didn't want to do anything to blow it. And not just because Jessica would be his most ambitious conquest yet. He'd never fucked anyone older than a college student, a real woman, and this one was hot as hell. More than that, he didn't want any gossip getting back to Professor Morgan about how he was too busy being a cooze-hound to pay attention to his new responsibilities. Before he even realized it he'd pulled up Kate's Facebook profile and was gazing idly at the photo of her in her dark pantsuit ("Nice lady, Nice body"). He did a quick search for any tagged photos that her friends might have posted, not for the first time. Too bad, he muttered when nothing came up. She probably kept a close eye on her privacy, like a lot of the female professors he'd had. But then he had an idea. He'd figured out one night, by chance really, that if you searched for the woman's husband online you could sometimes find images of the wife that she would never have put online herself, and that she had no idea were out there. Older guys were usually way less careful about that kind of thing than older women. Hell, some of the guys, the ones with the really hot wives, may have subconsciously wanted people to find the pictures and admire them, a way to proclaim their status as an alpha dude, so to speak. He searched for "Brian Phare" (it felt weird using his regular name) and scanned through the results. Bingo. A profile on some website for sharing photos. There were quite a few albums to look at, but Chad was tired and he didn't want to spend much time sifting through them. So he clicked on the first one he saw that looked like it was taken somewhere warm and wet, somewhere near a beach. Bingo again! An album from a long weekend Professor Phare and Kate had spent in Puerto Rico during winter break. There were probably twenty or so pictures of her in the album and he'd have to study them more closely another time. Some of them were very nice. He liked the one of her in the purple scoop-neck standing on a hotel balcony with the sun behind her. And the one of her shot from below as she climbed the stone steps of some old cathedral. The white tennis shorts weren't particularly tight or short but it was the first time he'd seen her long, thin, surprisingly muscular legs (she must do yoga or something) and the best sense he'd gotten yet of what kind of ass she was packing. All signs pointed to a truly memorable one, firm, wide, and heart-shaped. Chad looked down and noticed that was cock was almost completely hard now, at a forty-five degree angle from the floor. He thought about jerking off but decided against it. He felt kind of bad intruding on his female professor's privacy in this way. Her husband might have realized these photos were public, but she sure didn't. But like he'd already said, this was pure late night fantasy. Nothing could possibly happen between them. So who did it hurt, really, to look a little. He continued scrolling through the images. The professor couple looked happy and fulfilled together. He thought of going back to bed. Even yawned once. But then there it was: bikini shot. Sweet Jesus! She put the porn-star from the step-mom video to shame. She was standing knee deep in a stream near some waterfall (seemed like a rain forest) and smiling kind of shyly, but straight at him, in a string two-piece that was way more revealing than anything he ever thought she'd wear ("a real wildcat"). She'd just been in the water and the tiny suit was clinging to her in all the right places. The whole sight of her was awe-inspiring. She was toned and strong all over but soft where she should be. Her breasts were unbelievable! Heavy, firm, and shapely. Maybe the best he'd ever seen. He looked down and noticed that his cock was pointing straight up at the ceiling now, like it wanted to launch itself into orbit or something. It looked longer and thicker than he'd ever seen it. He reached down and grabbed it and started jerking it hard while he drank in the spectacle of female perfection on the screen in front of him. This was pure fantasy he told himself. There was nothing wrong with and it wouldn't hurt anyone. He pictured her walking across the stream toward him, smiling playfully with her big brown eyes as her hips swayed and her tits bounced a little. And before he knew it he was cumming hard, a rope of sperm so long and powerful he thought it might hit the ceiling or the wall or something. "Ahhhhhhhhh," he groaned loudly, then settled back in the desk chair, stunned by the force of his orgasm. Then he laughed to himself as he realized he'd ended up shooting sperm all over his computer screen. He'd have to clean it in a minute, but for now he just wanted to catch his breath and enjoy the sight of it hanging there, in thick drops on Kate's face and chest as she smiled playfully back at him, almost laughing along with him. Part 6 Kate stepped out of the shower and began what she already thought of as her new morning "routine" (she'd make time for some early morning yoga when they got into the mountains). Not even bothering to put on her bathrobe this time she strode straight over to the little desk with her laptop and opened her favorite video to the scene with the brunette professor and the skinny blonde guy. She still had cramps and a headache (would her period just start already!) but she felt far more refreshed. She'd been able to sleep last night at least. She spread her legs as wide as she could as she leaned back in the desk chair and put one of her feet up on the desk, still dripping wet from the shower and naked as the day she was born. She'd gotten really turned on last night by the part where the female professor does that, where she grabs the skinny blonde guy by his short hair and pushes his face into her lap, throwing her foot up on the desk as she smiles archly. Kate already had her hand on her clit making slow circles. She had a busy day ahead of her and she need to get a move on. She'd realized last night that she liked the scene even better than at first. There was more to the set-up than she'd realized, and more positions when they finally did start screwing! And she'd been able to watch it with headphones this time. This was the part where the guy is telling her that he's too stressed out and distracted to concentrate in her class, and she's listening to him sympathetically, devouring him with her eyes. He was kind of cute for a porn star, with sensitive eyes and just the kind of lean, muscular body she liked best. Soon the professor would be jerking him off while she told him to stop worrying so much. The whole taboo aspect of it—the female professor was almost maternal at times and the male actor made it seem like his character kind of looked up to her—really got her juices flowing for some reason. This shouldn't take long at all. She'd been so tired after all the orientation sessions yesterday that she'd fallen straight to sleep around nine, reading some emails in bed. But then she'd been woken up again around midnight with the headboard shaking and her mattress rocking. Here we go again, she thought. Was that Elise in there or some other girl this time? Maybe Ellen. Hopefully not Jessica. That could mess up the chain of command once they got to the mountains. She was grouchy from being woken up, and she was sick of the humidity, so she ripped off her little night-shirt and threw it across the room. She wasn't wearing any bottoms. Good thing she hadn't started bleeding. She lay back on the mattress and tried to do some breathing exercises she'd learned from her yoga instructor, contracting and relaxing each muscle in her body from her feet upward. When she got to her chest she realized that that her breasts were jiggling again in time with with the thrusts of the couple next door. In time with Chad's thrusts, she caught herself thinking. She was kind of enjoying it, actually, that familiar rhythm. God she needed to get laid. Her cramps were coming on again as her sleepiness began to wear off "So big, so big, Chad, ugh" Yeah it sounded like Elise alright. Her mating call, Kate laughed to herself. She wanted to masturbate and get back to sleep, but with Elise squealing like that it was never going to happen. She felt a mounting dislike for the girl. If only it was the sound of male grunts coming through the wall, Chad's grunts she caught herself thinking. That might do the trick. This whole vibrating bed thing was kind of a turn on, she laughed again. If she closed her eyes and thrust her hand inside her, like she was doing now, it felt almost like she was actually being fucked, which was what she wanted most in the world right now, the whole focus of her menstruating brain contracted to the empty space between her legs and what she could do to fill it. Her period really did turn her into a walking vagina. Why couldn't Brian be here? But the soundtrack Elise was providing was just awful. It ruined the whole effect. Suddenly Kate remembered that before bed last night she'd found her headphones in the bottom of her purse. Maybe if she found something else to listen to she could get herself off. Maybe she could even watch that scene with the female professor and the blonde guy. She reached for her laptop on the night table beside her and had the video playing in a heartbeat. This was much better. Ten minutes later and she was riding the edge of a big orgasm. The video had such a hot set-up! The guy was all shy and embarrassed at first, and the professor was nurturing as she took him in her hand and mouth. But then halfway through the roles reversed. The student took charge and started giving the professor a serious pounding. He flipped her over on top of the desk and started screwing her from behind. The professor in the video had a butt just like hers. Kate arched her back and quickened the pace of her strokes as the mattress started rocking harder, her breasts gyrating in circles now as she rotated her hips. She was close. And the guy had a body just like Brian's when he was younger. Just like Chad's, she caught herself thinking. He could be a porn actor himself if he wanted to, judging by that photo of him in the speedo. And the actor had a magnificent dick. A little longer than her husband's (maybe ten inches?) and massively thick, with a big, bulbous head. She loved the sight of it on his skinny body. She imagined it thrusting into and out of her in long, powerful strokes, the boy's muscular hips doing what nature had so clearly made them for. "Ugh, fuck me, big, so big," Kate cried out suddenly as she jammed her fingers up her pussy hard and fast. What the fuck, Kate, she thought to herself, the sound of her own cries over the soundtrack of the video jolting her back to her senses. Had she actually just said that? And had she said it out loud? She was horrified, but she couldn't deny that the illicit thrill of it, and the danger of being overheard, had sent her to a new level of physical pleasure, the first wave of a massive orgasm beginning to build in her stomach. She ripped out her earphones so she wouldn't get too carried away. "Yeah, harder, fuck me, big," she gasped out again, being careful not to be too loud, in a husky call she barely recognized as her own. This was crazy! What if someone heard her? The mattress was rocking harder than ever. She thought she might fall off the bed. She pressed the soles of her feet into the mattress and lifted her ass up high, jamming four fingers up her wet gash, then withdrawing them quickly, then jamming them in harder. "Ugh, ugh, ahhhhh, ugh." O my god. Kate almost came right then. It was Chad's grunts coming through the wall this time as he slammed the headboard and her mattress rocked! Her whole body was on fire! She took her free hand and started mauling her tits. She wondered how Elise must be feeling in there, being fucked like that. Kate wasn't even in the same room with Chad and he was pounding her mattress so good she was about to lose her mind. "Fuck me, god, so big, so good." "Ugh, ugh, ugh, ugh." And then she lost all reason, picturing Chad on the mattress with her on his knees in front of her, between her legs, looming above her with his black hair and his deep blue eyes. She wrapped her legs around his waist tighter, her ass high off the bed in his big hands as he started to fuck her more powerfully, pounding her pussy with long, hard strokes. "Ugh, ahhhh, Ugh, ahhh." "Hard, yeah, so big . . . Chad." "Ugh, ugh, ugh, ugh." "Fuck me, Chad, so big, fuck." It was too much for her. Her orgasm hit her. It just kept going and going. Then she sank down into the mattress, exhausted, as it suddenly stopped moving. Next thing she knew she woke up refreshed and cheerful and headed for the shower. And now here she was naked at her desk and starting the day off right by watching the same scene again. "What the hell had happened last night," she thought to herself. She didn't usually make much noise in bed. She thought of the way that many kinds of female primates would use "copulation calls" before, during, and after sex in order to incite males in the group to mate with them and to encourage the male to ejaculate better, thereby ensuring reproduction. She thought of Brian's theory that for chimps these calls contained lots of information about the female's reproductive status (they tended to be more frequent as a female approached ovulation, and with a tone the males found more attractive) and about the status of the male that was "inspiring" her sounds (the calls tended to be louder and more musical when she was mating with a high status male). She'd always hated that theory. It was one of the things she was trying to challenge with her research on bonobos. Advanced Primatology Ch. 03 Part 1 Chad couldn't believe how hot Jess looked when she came downstairs in her scarlet Rutgers t-shirt and a pair of tiny shorts that showed off her long, lean legs and her big ass. He loved the way that girls started looking when they got a little older. Fuller and more substantial. Elise's tits were great, yeah, but Jess was in her mid twenties now (a grad student) and hers just had that little bit extra: a little rounder and heavier, but still firm and high and pointing upward when you saw then bouncing from the side, like Chad was right now in the form-fitting t-shirt. Chad pictured the photo of Jess in the bikini in Argentina. The one from the side where she was looking at the camera and smiling flirtatiously, with one hand on her hip and the other hand holding up her long brown hair. She was kind of turned a little at the hips and she was sticking her ass out, full and ripe, and she was sticking out her tits too and they were definitely juicy. Today she was wearing red, Chad noted, and maybe it was because she was ovulating that her body looked so ripe and he couldn't take his eyes off her. Jesus. Maybe he should have jerked off to her before he came downstairs. He wanted to have a clear head today so he could do a good job as team leader and learn as much as he could about the chimps they'd be studying. Professor Morgan's lecture yesterday afternoon had been really interesting, more passionate and more deeply insightful about the apes than a lot her lectures had been last term, and he wanted to be able to pay close attention to what she might say today. Maybe he still had time to sneak upstairs and rub one out. "Chad are you even listening to me," said the girl next to him at the table. Chad turned to face her and gave his friendly smile. It was the cute redhead with the freckles and the thick wavy hair and the scrunched up nose with green eyes. Ellen. He couldn't remember whether he was supposed to be acting nice and friendly to her at the moment or more teasing and flirtatious, more aggressive. Friendly was the safe bet. "Of course I am. It's really interesting." Ellen smiled back at him and kind of dropped her head to the side a little. Chad turned toward Elise and made a note that she was really pissed at him, leaning backward in her chair with her arms folded across her chest and frowning. Chad leaned back in his own chair and looked right back at her, letting his eyes travel slowly down the front of her. He liked the way her folded arms pushed her smallish tits together and made them sit higher and fuller on her chest, in the blue v-neck. He turned back to Ellen and looked straight at her now and dropped his head to the side. Her face was cute and he'd just remembered that she had a cute body too. Part 2 Kate walked into the breakfast room where most of the undergrads and Karin and Jess were already eating. She looked hot and she knew it and she liked it and that bothered her a little and it pissed her off too. She felt the room get quiet when she entered it but she just kept on walking, nodding to Jess and Karin as she tossed her briefcase on the table and strode right over to the buffet for a cup of coffee and a croissant, not worrying at all when she had to stick her ass out in the tennis shorts to reach the bowl of pastries, her backside to the student tables. "Let 'em look," she thought, "little pervs." She looked great and she had more important things on her mind. She grabbed a croissant and a muffin and picked up her coffee and marched right over to the women's table and sat her ass down. "Okay," she said to the younger women (she had their complete attention) "I'm going to do the first session this morning as a surprise question and answer. To review what we went over yesterday. I need the kids to be sharp before we get out to the field site. And we leave tomorrow. And if I have to be a little bit sharp with them this morning to get their attention then that's how it is." She turned to face Jess who looked bright-eyed and alert in her no non-sense t-shirt and her comfortable shorts. "Jess I need you to go upstairs and get all of the undergrads who aren't down here yet out of their bedrooms and at a table eating breakfast. No staying up there masturbating half the morning." She smiled and raised her eyebrows. Jess laughed and stood straight up and walked out of the room to the elevators. Kate felt awesome. She was being a complete bitch and she liked it and her whole body was tingling. And more than that, she could tell that Jess and Karin liked it too. It wasn't just her that had a lot riding on this trip. They had things they wanted as well: a dissertation topic and a good job. And to have a successful trip they needed to have a strong leader. She turned to Karin. She was such a beautiful and soulful looking young woman and Kate sensed a lot of potential in her. She wanted to tap into that more deeply on this trip because it would be good for both of them, and it would help them both achieve what they wanted to in their lives and careers. "Karin I need you to come in after the question and answer session to go over everything again with the kids. Be patient with them. Bad cop, good cop. You know the routine." Karin smiled and nodded. "Then I need you to start organizing them into teams for the more practical stuff about getting the equipment prepped and packed and ready for the flight tomorrow. Actually, we can give that to Elise and Chad." She pushed her chair back and stood up and faced Elise and Chad's table and called them over to her in a clear loud voice: "Chad, Elise, I need you over here for a minute." They both looked right at her. Then they pushed their own chairs back and stood up and walked straight over to her. Part 3 Kate was on fire. She was laying it down to the kids like she never had before and she was in complete control of herself and no one was thinking about anything except her and what she was saying. They were all looking straight at her. And it wasn't just because she had just snapped at a couple of them when she saw them texting or when a couple more had gotten busted for obviously not paying very close attention to an important part of one of the sessions yesterday. It was also because what she had to say to them was fucking brilliant and she was saying it in the most compelling way. She felt like she'd finally figured out her own way of doing this, her own style. Firing questions at the kids and giving them a warm pat on the back if they gave an answer she liked and a sharp kick in the ass if it wasn't good enough. So far Chad and Elise had been excellent and she could tell Courtney had a lot of potential too. But the other two guys and a couple of the girls seemed like they'd just been kind of drifting along yesterday and she couldn't have that once they were out in the field. "Okay. So why do chimps have sex?" "To reproduce," said Elise. "Good. Why else?" She rolled her eyes and shook her head and kind of held her hands out toward them and waved them in frustration. "Come on. It's not rocket science. Do you want to make a baby every time you have sex?" They all laughed. "Then why do it? What else do the chimps get out of it? Come on. Think about bonobos. It's not totally different than with chimps." "Peace and quiet," said Chad. "Group harmony." She was impressed. She smiled at him and nodded her head and waved her hands again a little so he would keep going. She felt her breasts start bouncing as she moved her hands excitedly but she didn't let it distract her. "Yeah, and how does sex give them that?" Chad looked at his notebook for a second and then raised his eyes to hers, the deep blue eyes she'd been fantasizing about last night when she fucked herself silly to a shattering orgasm. "Because it helps relieve stress and promotes cooperation in a tight-knight group." Does it ever! thought Kate, as she smiled and nodded. "Good. And how do we know that? Come on. Someone else this time. Courtney, your turn. "Well, sometimes when there hasn't been enough food for a while and a group of bonobos finds some ripe fruit tree or something, well, everyone gets all excited about it and conflicts start to break out. Sometimes then they'll start to have, what's it called, a 'general copulation.'" "Excellent Courtney. And what is that? What is a general copulation?" One of the weaker male students in the back shifted in his seat a little and started answering: "It's when everyone starts having sex with each other" he began, kind of slowly but carefully too. He was sitting up in his seat a little higher now and making better eye contact with Kate and just acting in general like he gave a shit about what they were all going to be doing in the rain forest for the next month. "Go on," she encouraged him. "Yeah, well, there's too much tension, and the high status apes are afraid that there's going to be violence and maybe a baby might get killed by accident or something so they start encouraging everyone to have sex with each other. All different kind of pairings: intercourse in all kinds of positions, females rubbing their genitals against each other, males rubbing their penises together." "O I see you were paying attention to that part," she flashed her eyes at him as she said it. Everyone laughed, including him. He seemed okay. And then she smiled too. "Great. So all I'm saying is that when we get to the chimps we want to be looking for that kind of thing all the time. It won't be as obvious as with the bonobos but I think it's happening. And I think if we look really carefully and are all really on top of our game in terms of being up and out there early and knowing what we're doing, and really sharp about having the equipment working and everything packed where we can find it, then I think we're going to see some amazing things out there." She scanned the room and all of the kids were nodding at her and looking serious and alert. She nodded back at them. Then she clasped her hands behind her back and looked down and started pacing again, back and forth, in the narrow aisle of carpet between the first row of seats and the podium. She was so close to the kids in the front, like Chad and Elise and a couple of the other bright ones, that she could almost smell them. It was hot and humid and everyone was sweating. A couple times when she almost tripped over the slide projector cord she was afraid she might fall into one of their laps or something. But it was good to get right on top of them like this once in a while. Right up in their faces. She could sense that. Their eyes followed her from one side of the room to the other. She knew what they were seeing. The tennis shorts were still too tight on her ass and her boobs were still swollen and they were sticking out almost obscenely in the purple scoop-neck. But as long as they were respectful about it, as long as they didn't make it obvious and it didn't keep them from doing their jobs, she was fine with it. They could look all they wanted at her full, womanly body, even fuller than normal in the right places because she was about to get her period and she'd just gone off the pill. And when they got to their rooms later that night they could do what they wanted while they thought about it and wished they could have it there with them, imagining her doing all kinds of things to them as they stroked themselves off or had sex with one of the other undergrads. She unclasped her hands behind her back and gave them a full view of her ass now as she started swinging her hips a little while she paced. That should give them something to remember tonight, she laughed to herself, something to aspire to. She stopped and turned to face them. She was standing in front of Chad and he was sitting up and looking right at her with a notebook full of notes but also kind of leaning back in his chair to give her more room to move around in. "Okay. Good. But we're also going to see this." She pushed the clicker in her hand and a new image appeared on the screen behind her. It showed a picture of a male chimp facing the camera with his mouth open and his hands beating his chest and a shiny red hard penis, about the size of a finger, sticking straight out at the kids. Everyone laughed again, louder this time. "So who can tell me how males in a group will announce their presence to females in estrus, in heat?" Courtney jumped right in: "Lots of ways. But the one we concentrated on yesterday was through displays of penis size." "Good. And what kind of behaviors does a large penis and large testes tend to correlate to?" "Aggression, violence, and social dominance," Courtney piped up again. "Good. What else?" "Reproductive success with the most popular females," Chad jumped in. "Yes. Good. That's what we want to stay focused on. That's our question. Why do the males with the biggest penises tend to be the most dominant, and the most aggressive, and why do they get to mate more often with the highest-status females, the most popular females, when they are most fertile?" She scanned the room again. They were thinking seriously about her question and they seemed absolutely riveted by the new direction she was taking things. "Anyone?" She put her hands on her hips and stood up straighter, puffing her chest out a little as she waited for an answer. She was really worked up now and she was sweating a little and her nipples were rock hard and sticking straight out through the tight purple shirt as her lungs heaved. Chad went first, rising to the challenge. "Well, weren't you saying yesterday that that's kind of the wrong question?" Her eyes flashed at him: "You tell me." "Well, what I heard you saying was that you had to separate the question about why males with bigger penises tend to be more aggressive and violent from the question about why they are so successful at mating. They may not be connected after all." She was impressed, but she wanted to push him a little further. "Good. So, if it's not because of the threat of violence, primarily, then why do the most popular females tend to select the males with the biggest penises and the largest testes, the males who are most aggressive, on their most fertile days?" "Because it's the best tool for the job," Chad shot back immediately, not embarrassed or self-conscious in the least. "It's like looking around for a stick or something to scratch their backside with. It's just a better tool." All the other students laughed, and even Jess and Karin joined in. "Good," Kate smiled. He'd been listening closely and she was impressed, even flattered. "And why is it the best tool?" No one answered. Chad seemed a little less sure of himself now, a little more hesitant. Kate put her hands on her hips and stuck out her chest again, practically looming over Chad as he leaned back in his chair to give her room. It made his pecs and shoulders stand out and it showed off his flat stomach in his tight "UNC Soccer" t-shirt. He had some stubble on his chin and he looked fantastic and he smelled fantastic too. Kate breathed in deeply through her nose and caught a whiff of his heavy scent as she felt her crotch moisten. She wondered if he could smell her scent too. She was pretty sure she'd started bleeding and she was pretty sure she could smell it herself, so she was glad she'd put a tampon in before rushing downstairs in her short white shorts. She'd been out of control this morning. "Come on people. This is going to be important when we get out in the field. You have to know this cold! What can female chimps have that every other female primate can have including humans?" Ellen's hand shot straight up: "Multiple orgasms. Female chimps can have multiple orgasms. And they tend to have more frequent and more lengthy orgasms when they mate with the males with the biggest penises and the largest testes." Kate smiled. "Nice to hear from you this morning Ellen. I can see that at least something I said yesterday got your attention." Everyone laughed. Ellen looked a little embarrassed but basically fine. "So why do big penises give the females better orgasms and why does that make them the best tool for the job?" Elise answered this time. She looked like it was starting to click for her. "Well, for a bunch of reasons. For one because it ejaculates their sperm closer to the female's ovum so it has a higher chance of getting there before anyone else's sperm. Female chimps are promiscuous so a lot of times they'll mate with more than one male while they're fertile. But it also helps them be first in other ways too. It's not just the size of their penises. It's also about big testes that allow them to ejaculate more often and more voluminously." "Excellent. I'm impressed. What else?" Elise wasn't sure. "Because it gives them more pleasure," said Chad. "That's what your theory was yesterday. That the popular females mate with the well endowed males first, and most often, because it gives them the most sexual satisfaction. You even said that the female orgasms might create a suction or something that actually draws the sperm into the ovum." Kate was impressed and delighted. The class was doing great and Chad was being a great team leader and he looked and smelled great doing it. She paused to plan her next remarks and while she did so she suddenly had a crazy idea that she should just march right up to him with her swollen breasts and her glasses and reach into his shorts and fish out his cock and stroke and blow it like the female professor in the video from this morning. I bet the other two guys would start trying harder then, she thought to herself archly. "Good. That's a good start. We're going to be asking some questions about that theory when we get into the field. But you guys are getting there. Keep it up. I'm going to hand you over to Karin now." She turned her back to the students and strode out of the room, sashaying a little so they'd have something to remember her lesson by. Part 4. In the bar that night Chad couldn't take his eyes off Kate. He needed to get working on Jess tonight, he reminded himself, if he was going to have the best chance of having sex with her, unprotected hopefully, while she was probably fertile. But for now he just wanted to observe his professor a little and see what kinds of signals he could pick up. She had her hair down now and it was a little wavier in the humid air, and she looked relaxed and happy, flashing her big brown eyes at Jess and Karin and any of the undergrads who came over to chat with them at their little table near the center of the room. He noticed that Kate had let Jess get her a second drink tonight and that she'd drunk about half of it and was starting to be a little more playful with Jess and Karin and whatever undergrad they were chatting with. At one point Courtney walked over to them, stumbling a little with the effects of her third drink, and before he knew it she'd grabbed Jess and Kate by the hand and led them straight over to the dance floor where they started swaying their hips a little and laughing with each other as they held their drinks, careful not to spill them. Chad was practically losing his mind with the lust and confusion. Professor Morgan looked fertile too, almost bursting out of her shorts and shirt (purple, kind of reddish, he observed) and her voice sounded sexier today, and she'd even smelled different (stronger and saltier) when she'd waved her ass in his face during her lecture this morning. And more than that she looked, how to put it, she looked like she'd enjoy nothing more right now than to grab the hottest guy she could find and drag him up to her room and screw him senseless and then send him home when she was done with him. She looked like her body was on fire. But even so, Chad also noticed, he wasn't picking up even the slightest sign that this could really ever happen, that she was actually receptive to an actual fuck from one of the actual people in this room, including him. And it was driving him crazy and his balls hurt and he felt like he was losing his mind. Advanced Primatology Ch. 03 Courtney and Jess and Kate had all put their drinks on their nearest table now and they were swaying their hips a little faster and laughing a little harder too. Chad watched one of the other guys stride toward them, and he was surprised and impressed. He knew that walk and that way of holding yourself. The guy looked like he was going to push himself inside the little circle of females to try to dance along with them and maybe even to have the first dance alone with Professor Morgan. The fast song ended and a slower one started. It was the right moment and Chad decided to push his luck. He walked straight over to the group and cut Kevin (the other guy) right out of the game. "First dance to the team leader?" He smiled at Kate and she smiled back as he took her in his arms, making sure to stand stock upright and keep an appropriate distance between them while they made a few simple steps together. Chad was light on his feet from all his time on a soccer field and when Kate realized what a good dancer he was (she really liked to dance) she started to loosen up a little and let him take the lead, turning her once or twice and then pulling her back toward him quickly, a little closer this time. They took a few more steps together and smiled at each other and then the song ended. Kate bowed her head at him and thanked him warmly and then walked off the floor. He watched her walk over to the table where Karin was still sitting and tried to tell if she was swaying her hips a little more than she normally would and maybe swaying her ass along with it. He couldn't tell. But there'd been a split second when he turned her and pulled her a little roughly back to him when she'd kind of yielded to him and he'd look down at her and caught a glimpse of the tops of her breasts pushing up out of the purple scoop neck, so close to him he could almost taste them. Thank god the song had ended then. He'd popped a huge boner. He watched Kate grab her briefcase off the table and say goodnight to Karin and stride out of the room in that new way, her hips swaying more obviously this time and her ass swishing a little in the tight shorts. Karin was at the table alone now and Chad decided to push his luck some more. He reviewed his plan. He needed to flirt with Karin in order to make Jess jealous so she would fuck him tonight, or tomorrow night at the latest, and maybe let him cum inside her while she was fertile. He didn't want to get her pregnant, and he sure as shit didn't want to be a dad, but he did want to have the hottest sex possible and to maximize his pleasure. And the thought of fucking girls bareback when they were at risk of conceiving, and their bodies looked the ripest, and they were the wildest in bed, and, if Professor Phare was right, when they were most likely to cheat with dominant males, especially if they were in relationships with "nice guys," well, that was the thing in the world that made his cock hardest, and made the girls cum hardest, and that made him cum harder than anything else. He walked straight over to the bar and got two drinks and then walked straight over to Karin and put one of the drinks in front of her and sat down and smiled. "Thanks," said Karin, smiling back at him. "You were great today. Really sharp." "Thanks," Chad smiled. "Why aren't you dancing with everyone else?" Karin smiled and laughed. She was older than Jess, maybe thirty, and Chad couldn't help but admire what the extra few years had done to her face and body, and especially to her full rack. You had to use your imagination a little to picture it in that loose-fitting, silky v-neck tank she was wearing but it showed just enough cleavage, and the round, full shape of her chest was visible beneath it. Chad wanted to pull the straps off her shoulders and take a long look at what she was packing in there. He could tell that Karin had seen him looking, but she was a little buzzed and it had been a long day and she didn't seem to mind too much. She kind of sat back in her chair and eyed him curiously. This was going better than he'd planned. Jess returned to the table (right on cue) and started flirting with him more obviously. "Hi Chad, you were fantastic today!" They drank and laughed and made small talk for a while and Chad learned some interesting things. He learned that Jess had moved to New Jersey from Argentina when she was fifteen and she thought of herself as the perfect fusion of Latina goddess and Jersey Girl. And she had a sweet, attentive boyfriend who she loved a lot and who she was practically living with but they still had their own apartments. And he learned that Karin would be getting married a month after she got back from the chimps and that her fiancé was also a sweetie and he was a psychologist so he "really got her" and "took great care of her." And he was a little bit older than her and wanted to start a family right away but she wasn't sure. She needed to get going on getting published and finding a tenure-track job and this would be her last trip to the field before she put her shoulder to the wheel. And Jess got carried away and even told him that Kate and her husband Brian were trying for a baby and that she was feeling crazy because she was about to get her period and she'd gone off the pill. Chad was rock hard as soon as she told him. It all made sense now. He noticed Karin shaking her head at Jess and frowning, but laughing a little too. And he told them that he'd been raised in Appalachia by a single mom with a drinking problem and he'd never known his dad, and thank god he'd been good at soccer because if he hadn't been he'd never have been able to afford UNC, and then he wouldn't have gotten to take awesome classes like the ones that they'd been the TA's for, and he never would have been able to be on this trip which he was really excited about. And they believed it, and they ate it up, because he meant every word of it. He thought that Jess might jump him right then and there and even Karin seemed to be warming up to him. It was the right moment. "What do you say, Karin, can I get one dance from my favorite TA," he shot a friendly smile at her. "It's our last chance before the hard work starts!" The double meaning wasn't lost on Karin and she smiled and shook her head as she pushed her chair back and stood up, giving him a good, long look at the whole length of her. She was wobbling a little from the extra drink and Chad's heart was racing. "You're sweet, but no thanks. It's a big day tomorrow." She grabbed her leather folder off the table and walked out of the room, stumbling a little, and swinging her hips in her brown stretch skirt. Jess stood up and gave him her big, bright eyes. "Let's dance!" she said, and took him by the hands. Thirty minutes later and he and Jess were all over each other on the patio out back in the salty air with the sound of the surf crashing in their ears. He had her up against the wall and they were kissing passionately. He had has right hand under her Rutgers t-shirt and his left hand inside her shorts, which were unzipped now and riding down her hips. He stuck his tongue in her throat and his finger between her wet lips and she moaned a little and started to ride his hand while his other hand found her nipple and pinched it hard. He wondered if he should try to fuck her right then and there for the sheer hotness factor and surprise of it, or take her up to his room where they could take their clothes off and screw each other properly. It was all about deciding how to get her to the point where she would let him enter her without protection and maybe, if he were lucky, let him cum inside her. He decided that quick and dirty was the best approach and he took her right hand by the wrist and shoved it down the front of his shorts, making sure that she got a good feel of his shaft and balls. Her eyes went wide as he fingered her harder. She stroked him a little and moaned in his mouth. Then the pace picked up and he had two fingers inside her and she was stroking him more roughly and he felt like he might pass out from lust. He pulled her t-shirt up and her bra cups down and put his mouth to her breasts and started to lick them and bite them. She put his cock between her legs and let him grind a little against her wet lips. It was time to push his luck. "Can I fuck you a little? Right here? Just a little?" His mouth found her neck and she started to stroke him a little faster. "I don't think so, sweetie, I don't think boyfriend would like it." Chad felt his cock get harder in her hand. "You sure? Just for a minute and then we'll go back inside," he kissed her on the lips and gave her his sweetest smile. "We better not, sweetie, I think Professor would be mad." They both laughed and when she opened her mouth he put his mouth right over hers and stuck his tongue inside. He pushed her back with his strong hips until her ass was against the stucco wall and then he ground his hips and put his mouth to her ear. "Awww Jess, you're killing me," he was a little buzzed and that always made his accent thicker, which wasn't a bad thing for him because it drove most girls wild. "Just let me put it in, just to see what it feels like." Jess pushed her hands into his chest to get a little space so she could see him. She spread her feet a little wider as she slowed her hips, still grinding him though. "You got a condom for this big boy," she asked, looking down at it, longingly and maybe with some disbelief too. Chad shook his head. She laughed at him and rolled her eyes while her hips kept grinding and her crotch got wetter. "Maybe next time then, sweetie," she smiled wickedly, "maybe next time team leader will bring the right gear for the job." Chad laughed. They'd been flirting like crazy this afternoon while they'd been prepping the equipment for the flight tomorrow. He leaned in closer to Jess until his mouth was by her ear. "I think I brought the right gear, baby" he purred in his thickest drawl. He hadn't shaved that morning and he had some stubble now and it drove Jess crazy when he kissed her neck. Then he looked at her and she was kind of pouting at him and making fists on his chest, like she was angry or something. But not really. And she was slouching against the wall now and that changed the angle of her pelvis. So the head of his dick was pushing into her now as her lips started to open. "I don't think so, sweetie," she moaned, "Kate said not to." Chad thrust his hips forward a little. She hit her fists against his chest, playfully, as her pelvis tilted toward him. "No what?" asked Chad, kissing her full on the mouth and starting to circle his hips. "Duh, no fucking the students, silly!" "How about the student fucking you, then?" he drawled. Jess hit his chest again and laughed and her hips stopped moving. Then she did something completely unexpected. Something that had never happened to Chad and that left him dizzy and rock hard and kind of flushed and crazy. She looked straight at him and pushed him back with her strong arms, and pulled her shorts back up her hips and zipped them and then rearranged bra. Her tits looked full and ripe in it, and she knew it, and she kind of pushed them together for him and smiled at him, wickedly again. "Professor's rules," Jess said, "You've got to learn that, sweetie. Kate's trip, Kate's rules." Then she turned and walked away. Chad's head was hot and his brain was exploding. What the fuck, he asked himself, what the fuck just happened? She'd been right on the edge and then she'd pulled herself back from it and it had been Professor Morgan who'd made her do it. And he felt pissed at Kate and hurt by Jess and he wanted to screw her so badly that his balls hurt from the thought of it. He pulled up his pants and zipped them and walked straight back into the bar to find her. She wasn't there. He was losing his mind. He took a quick look around to see where Elise was, and who she was with, and what kind of mood she was in. But she wasn't there either. On the dance floor he spotted Ellen and Courtney hanging all over each other and laughing, wasted off their asses. He walked straight over to them and smiled and they both smiled back. Part 5 Kate woke up at midnight with her mattress rocking again and the headboard pounding against her wall. She'd been waiting for it to happen, and she'd wanted it to, and when it finally started it was like an electric current straight to her crotch. She'd gone to bed naked almost as soon as she'd gotten upstairs, and she hadn't masturbated then because she was pretty sure that Chad would be fucking someone tonight in his bed. She wanted to be primed and ready when it happened so she could fuck herself silly to the rhythm of Chad's thrusts and the sound of his groans. Then she'd get a good night's sleep and wake up refreshed and energized. It had worked for her last night, and today there'd been real progress in the group, so she didn't see any reason to change up now. The minute she heard them and felt the mattress start rocking, and saw her chest start bouncing, she placed two pillows underneath her butt and four fingers in her vagina and started mauling her chest and making quick, hushed cries. "O Chad baby, fuck me, fuck me just like that." "Ugh, ugh, ummph, ahhh." Chad started grunting right away, almost like he'd heard her, and was answering her (which Kate was pretty sure was impossible). She opened her laptop to the photo of him in the speedo, which she'd made sure to have up on her screen before she went to bed so she'd be good and ready when the action started. She didn't want to bother with the video of the blond porn star, who was nowhere near as cute and hot as Chad, and who wouldn't get her off half as hard as he would. But she was going to borrow his big fat cock, so to speak, and imagine it on Chad for her little session with him here. She was pretty sure it was more or less the equivalent of Chad's anyway. She'd had more time to study the speedo shot by now (had she ever!) and she was almost sure that Chad was a little bigger than her husband, definitely with bigger testicles. God how she wished he could come over here right now and fuck her for real with his big cock. She loved her husband and she was about to make a baby with him and none of that had changed. But this was her trip, for her work, and this was her fantasy, and tonight she was going to wish for exactly what she wanted. She wanted to stand up and pound on the wall and tell Chad to get his ass over to her room right now and fuck a real woman instead of those squealing girls, to fuck her raw with his enormous shaft. And it was a fantasy so there didn't need to be any annoying details about birth control and such. She wanted him to fuck her raw because it would give her more satisfaction. She wanted him to fuck her raw and cum inside her pussy so deep and hard that the sperm would hit her cervix and she would came instantly on his fat tool. "Come fuck me Chad, come fuck me in my bed with your big fat cock." It took her a second to realize that she'd actually said it out loud, a little too loud, practically hissing and spitting as she lifted her ass up higher and started grinding her hips. "Ugh, ugh, ugh, ummmph. "You want to fuck me, Chad, you want to fuck me blind with your big tool?" "Ugh ahhh ugh ugh." "Come fuck me, Chad, come fuck my pussy and make it yours." The mattress was rocking just as hard as last night, and maybe a little harder, and Kate loved the sheer force of it. Her tits were bouncing so hard she thought they might fly right off her. She had her hand up her wet tunnel as far as she could get it but it still wasn't enough, and the frustration just made her feel that much hotter as she started rotating her pelvis and hissing a little bit louder. "Come over, baby, come over, Chad, come fuck me raw with your big dick." Kate could hear a female voice in the next room, maybe two female voices, but she didn't give a shit. She was timing her own groans so that she could drown out theirs and concentrate on nothing else except the feel of the mattress as it rocked wildly and the sound of Chad's grunts and the fire between her legs. "Fuck me raw, Chad, come over here right now and fuck me raw like a good boy." She looked down and saw the blood on her fingers but she kept right on going. Nothing was ever going to happen between she and Chad. And he was never going to see even the slightest sign that she was this hot for him, and that she fantasized about him pounding her while she got herself off. And no way would he ever know that it had practically become a habit with her by now, part of her normal routine. This was pure fantasy and she intended to enjoy it to the fullest. She felt so crazy and horny from going off the pill and trying to get pregnant with Brian and from all the sexual tension in the room today when she was laying it down to the kids, and then later on the dance floor when Chad cut off the weaker male and took her in his arms. And then he spun her toward him and looked down at her full soft breasts, served on a platter for him by the purple scoop neck. She'd wanted to grab him by the back of the head and jam his face between them. She was about to settle down with Brian and get tenure and have a baby and then everything would change. So tonight she was going to do exactly what her body wanted to, and fuck anyone who didn't like it. It might be the last time on the trip that she'd be able to masturbate like a madwoman like this. It was close quarters in the cottage she'd be sharing with the other two women once they got to the mountains. So tonight she was treating herself. And to treat herself well she needed to use the best tool she could find. Chad's body, and Chad's voice, and her ecstatic vision of Chad's naked cock plunging deep and hard into her unprotected pussy. "Fuck me raw, baby, fuck me raw, Chad." "Ugh, ugh, mmmph, ahhh." "Fuck me Chad, fuck me raw and come inside me with your big cock." She pictured Chad on top of her with the whole length of his body lying flat against hers and Kate's heels in his ass as she spread her legs out wide and used her strong thighs to pull him into her. He was holding her head in his big hands and kissing her full on the mouth while their tongues danced together and she stared into his eyes. He was taking his strong hips and kind of flinging them toward her so that she was thrown backward up the mattress every time he thrust into her. Then his big hands would slide her back toward him as he pinned her to the mattress with his shaft. She teased him a little, trying to slither out from under him. She could tell how hot he was for her because his cock kept getting longer and fatter and harder and hotter and she was reaching down between them and massaging his balls with her hand and telling him where he could put all that hot seed that was boiling inside him. "You want to come inside me baby? You like that don't you." "Mmph, mmph, ugh, ahhhhh" "You want to fuck me raw and cum inside me, you want to give me a baby with your big fat cock, you want to empty your big balls inside me and give me a baby?" "Ahhh, ahhh, mmmmph, ahhh." The wall was shaking so hard now that the plaster was falling off it and she was shaking too now all over and kind of shrieking a little as she lifted her ass off the bed. And then she was cumming and cumming and she get louder and louder and sort of blacked out for a minute. When she came to the mattress had stopped moving and she could hear voices talking in the room next door. Two girls she was almost certain, neither of them Elise. She closed her laptop and rearranged the pillows and went straight to sleep. Part 6 "Did you guys hear that," asked Courtney, when the three of them had finally caught their breaths. Advanced Primatology Ch. 03 "Hear what?" asked Ellen. "Sounds like the three of us weren't the only ones enjoying ourselves just now." "What are you talking about?" Ellen asked. "Neither of you heard that?" It wasn't so surprising really. Courtney had been straddling Chad's face with her thighs as he tongued her to orgasm and she'd been making out with Ellen who was facing her as she impaled herself over and over on Chad's porn star shaft, quaking with the sheer thrill of it. She looked like she couldn't believe this was happening, and couldn't believe how much she loved that it was happening, and not just because she'd never felt another girls tits before or had another girl feel hers, but because she was riding Chad bareback and she'd already cum two or three times in the last twenty minutes. Chad had run out of condoms from all the sex he'd been having with Elise (so he claimed), and neither of the girls had remembered to bring any with them to the reception, and Ellen was on the pill anyway so why not. And she was so hot from Chad and from the new thrill of making out with a girl that she didn't even notice, really, when Chad grunted a little louder and thrust his ass up off the mattress and shot a huge load inside her. She loved the feel of it. "Hear what?" asked Ellen. "Hear that girl screaming in the room next door." "O my god really? Who was it?" "I don't know, said Courtney, "I couldn't recognize the voice." "What did it sound like?" "It sounded hot. 'Fuck me raw, baby, fuck me Chad, come over and cum inside me with your big fat cock.'" "O my god. That's so hot!" "I know!" said Courtney. She leaned toward Chad and pushed her chest together for him, "Come fuck me, baby, come fuck me, Chad, come fuck me raw and give me a baby." Chad was absolutely floored. He felt like he'd been kicked in the stomach, and he was hot and sweaty and kind of dizzy, and his dick was rock hard and pointing straight up at the ceiling. He felt like he might pass out from the electric shock of it. "Looks like someone else in the group wants to fuck the team leader and it looks like the team leader likes it." "I wonder who it is," asked Ellen, "whose room is that?" Chad shrugged his shoulders. He lay back on the bed, his nerves crackling, and tried to think carefully about what he'd just been told. He didn't know what it meant, but whatever it was he liked it, and he was determined to push his luck and try to find out more. Advanced Primatology Ch. 04 Things get wild and wet in the mountains. Ever since she woke up this morning Kate had been in another world. She'd opened her eyes and stretched herself out long and slow and naked on the plush bed, remembering the force of her orgasm the night before when she'd pictured Chad on top of her and inside her while she urged him on. She felt calm and refreshed and when she got to the toilet she saw that her flow had been heavy last night but now it was much lighter. Maybe orgasms did that, she thought to herself. Hadn't she read that somewhere on the internet or maybe even in a scientific journal? That all the craziness and horniness she'd been feeling the last couple of days might serve an evolutionary purpose. That maybe those long, shuddering orgasms she'd been giving herself were designed to flush the uterine lining right out of her, so that her period would end more quickly and her body would be fertile and receptive again sooner, ready to mate with an attractive male and pass on her genes. Why did she find that so hot and alluring? This idea that her primate body and her primate brain were leading her down some preordained path, not the one she would have chosen herself, necessarily, but one that felt so deeply good and right that she couldn't stop herself. Well, whatever the reason her cramps were gone now. She stepped into the shower and started to soap herself off, noting that her shapely chest was still a little swollen and her butt was too. She felt around a little with her hand and noticed that her labia and clit were still engorged and sensitive. It felt good when her soapy hand and the hot water hit them and she wondered whether she should sit down at the desk with her laptop and try to take the edge off a little before the busy morning. But there was too much to do. She needed to grab a quick breakfast and then head straight for the lobby to make sure the gear got packed properly in the vans, so that there wouldn't be any screw ups getting it onto the little charter plane they'd be flying to Mahale and the mountains. She couldn't wait to get into them! She could practically smell the forest, still lush and green at the beginning of the long dry season. The first thing she was going to do after the charter plane landed, and after the little boat carried them over Lake Tanganyika to the lodge they'd be using as base camp, was to take her backpack and her camera and march straight up the green slopes behind the camp until she reached the forest line and the little stream where the chimps liked to drink sometimes in the afternoon heat. She'd been reading avidly about them, and especially about Group M with the missing alpha. She walked over to the mirror and thought carefully about the day ahead, admiring her toned body as she eased herself into her black bathing suit, the halter-top cut low down the front and hugging her hips and ass snugly, the most conservative one she owned. She inspected the results. Her breasts were still heavier then normal and they were a little unsupported in the halter-top, and that might be annoying with all the bending and lifting and hiking she'd have to do between now and the forest. But she was thinking about how amazing it would feel when she got to a good swimming hole—the first one she saw—and stripped down and dove straight in. She smiled at the thought of it as she pulled on her black yoga pants over her suit. Cute, she thought, as she turned and stuck out her butt. They were cropped at mid-calf and showed off her thin legs and the stretchy fabric was still tighter than normal around her backside, which looked firm and fit. She put her hair in a ponytail and pulled on a loose white linen shirt, long-sleeved, and buttoned it to the top. Then she undid the top two buttons so you could see the straps of her halter-top where they rose up to meet each other behind her neck. Nice, she thought. Brian always loved it when she wore this shirt, especially with the yoga pants. He was always sneaking up behind her and groping her and grinding her and reminding her of the racy comments her students wrote on ratemyprofessors.com. She caught herself wondering if Chad would like it. She had a lot to do today but one thing she knew for sure would happen was that before she went to sleep tonight she would get herself off again picturing him inside her, fucking her again, more slowly and quietly this time because she'd be sharing a cottage with Karin and Jess, but hard too so she'd cum hard and get a good night's sleep. Then she'd wake up rejuvenated and full of energy and ready to do her work, like she was feeling right now. She'd felt so creative and focused in the last two days, and so deeply insightful about the chimps, and she wanted that feeling to last. And even though it wasn't a conscious decision exactly, and she felt a little queasy about it if she admitted it to herself too directly, she'd already made up her mind that for the rest of the trip she was going to have a kind of "mental fling" with Chad. For the rest of the trip, or until her husband Brian visited in a couple weeks, she was going to be fantasizing about Chad and fucking Chad as often as she could in her thoughts before she went to sleep. She knew it was crazy and it didn't make sense and she didn't care. This was her research trip, for her work and her career and she deserved it. And she'd never done anything like that in her whole life, had a quick hot fling with a guy whose body she liked and whose eyes and hair she liked, and his smell, and who made her cum hard, a younger guy, because she'd been with just Brian since she was a teenager. And anyway she needed to do whatever she had to for her work with all the pressure she was under, and this was the thing that would make her feel the most creative, and the most relaxed, and help her be the best scientist and teacher she could be. Then she'd go home and write a brilliant paper about her discoveries on the trip, and get it published and get tenure and make a baby with Brian and start the rest of her life with him. And maybe she even needed to do this in order to be the best wife to him that she could be, to be his true equal, intellectually and professionally. So if she was going to be fantasizing about Chad again tonight, she reasoned, then it would help if there were a little sexual tension between them today, the way there had been yesterday in the lecture hall and on the dance floor. So she wanted to look good for him. She would be subtle about it, she told herself, but she wanted to get close to him too a couple of times, to smell him and maybe even feel his heat, so she'd have something to build on when she imagined him mounting her tonight, however he wanted to, and riding her to a big climax and a sound sleep and a productive next day. She shivered a little remembering her vision of him coming inside her last night while she begged him to fill her up and give her a baby, then blushed when she remembered how loud she'd gotten. Her "mating call." Designed by evolution to make her mate cum hardest and make him longer and harder so she'd cum hard too. She liked imagining Chad that way, with his cock naked and his balls ready to pump her full. Ever since she'd started letting Brian fuck her unprotected, cumming gallons inside her as her pussy contracted and pulsed around his shaft, ever since then she'd realized that this was the kind of sex that her body liked best, that it was programmed to enjoy the most, at least at this stage in her life: raw sex driven by the deep desire to pass on her genes as quickly as she could and as often as she could and with the best cock she could find. Too bad she'd have to be quieter in the little cottage in the mountains. She walked over to the night table and picked up her phone and sent a quick text to Brian in Europe. "Headed for the mountains. Will be in touch next week. Love you." There was no phone reception at the lodge and no internet either, so this was the last time she'd be in contact with him until she made a quick trip to the nearest town in a week like they'd planned. She wondered whether he'd be able to visit after all. Her crotch ached a little at the thought of having him there with her and having sex for real again with a real man in the cool mountain air as the insects chanted and the moon rose high over the wide, dark lake. She picked up her phone and texted him again, "Miss you. See you soon?" Part 2: Chad was practically laughing out loud at his good fortune in life. Here he was, a kid from Appalachia, on a boat carrying him across the blue expanse of Lake Tanganyika toward the little lodge with the Mahale mountains rising green and lush behind them. Somewhere beneath the dense forest canopy were the wild chimps, the ones he'd been so obsessed about since he took Professor Phare's class on "Primate Sexuality." That class had just raised all these maddening questions for him about what a human being is, and about why humans want what they want, despite what their reason tells them, and he was excited to maybe get some answers to those questions by finally seeing the chimps for himself. People were such puzzles. Take him, for example. Or take Professor Morgan. What were they doing here exactly? He'd already fucked three of the nine females on the trip and tonight he was determined to fuck the fourth, Jess, and he had a pretty good shot at her. And before the trip ended maybe he'd have to fuck all of them, maybe his primate body and his primate brain would want that and demand that. Maybe he'd even fuck Professor Morgan, who'd been screaming out his name last night through the wall while he screwed Ellen and Courtney to ecstasy for reasons he didn't even begin to understand but that made him feel hard and flushed and dizzy. Yeah, maybe he'd fuck her too, even though he was sure it would make her feel awful about herself, and even though he really liked and respected her and didn't want her to feel that way, and even though it would make him feel awful too because he liked and admired her husband, Professor Phare, so much. How do you explain that? And how do you explain what he was thinking about Jess as he watched her lean out over the bow of the boat in her tribal print bike shorts with her big juicy ass and her long strong legs. He absolutely had to fuck her. And it had to be tonight or tomorrow night because he was almost sure she was ovulating. All the signs were there. He knew he was going to have to use a condom if he wanted to get inside her tonight. He could see that now. He'd pushed too far last night. But maybe tomorrow he could fuck her the way he really wanted to, raw and hard and with her begging him to finish exactly where he pleased. The messed up part was that he didn't want to get her pregnant, he really didn't, but he was still determined to cum his absolute hardest inside her while she had the best chance of conceiving. How fucked up was that? And how hot! And where else to go but the rain forest and the wild chimps to get even the remotest fucking clue about why he wanted that and what it meant. Jess was standing next to Kate and Karin now in the bow of the boat and they were all facing away from him. Karin was wearing the same style of tribal print bike shorts as Jess, but hers were bluish while Jess's were pink. He pictured them trying them on together in the dressing room in some trendy shop in Chapel Hill before the trip and making a plan to wear them the first time on the same day while they laughed and rolled their eyes about how crazy it would make the boys. Girls were so predictable, he'd always known that, and now he was learning that women were no different. There had been lots of "accidental" touching and teasing and stuff while they'd been packing the gear this morning, and not just with Jess (the grad student). With Karin (the postdoc) too. He was beginning to think that he had a real chance with her. He smiled to himself as he took in her full, firm, thirty-year old ass and her dark hair, almost kinky now in the humidity. Yeah, he thought to himself, before the month was over he just might be shoving his long Appalachian cock up that sweet Jewish ass. And maybe he even had a chance with Professor Morgan. He couldn't see Kate's ass much now with the white linen shirt hanging down over it. But the shirt was a little sheer and you could still make out the gorgeous shape of her in the dark yoga pants. Her full hips. And from the front, he remembered, you could see the black bathing suit she was wearing underneath, the low cut one that showed off her phenomenal breasts, really amazing, hanging a little freer on her chest in the halter top and looking firm and succulent. He was a little hard now thinking that maybe he'd get to see her in that suit sometime soon, maybe even today. He'd gotten some nice long looks at her fine ass too in the yoga pants when she'd bent over a couple times to pick up a bag right there in front of him, almost like she'd planned it. And a couple of times when he'd stood up and turned around suddenly he'd been surprised and excited to find Professor Morgan right there, right in his space, so that his hard pecs had almost brushed up against her soft chest, almost pressed right into it. It had taken everything he had to back away from her and keep his distance, acting embarrassed and awkward, and even a little grossed out, like touching her was something he'd prefer to avoid. But that was the plan, the script he had to follow. She was a real woman, no doubt, but she was still a female like every other girl he'd ever scored with, and he had a method for these things. If he wanted to be offered a chance to fuck her, which he did want very badly even though he wasn't sure what he'd do if she ever gave it up to him, if he wanted that he had to make her think that he didn't want her at all, that it had never crossed his mind. He had to make her feel a little bad about herself and maybe draw her out a little, make her make the first move. So he'd been flirting with Jess and Karin like crazy and looking for opportunities to make Kate feel like she was a little too old for him, and a little too much, and he didn't like being near her. Part 3 Kate was pissed at herself and at everyone else in the group and at the whole world too, including the fucking apes. She'd hiked up to the forest as soon as the boat landed but she hadn't found any chimps and she hadn't found a good swimming hole either. And the whole time the head naturalist in the park, Roger from South Africa, who'd met her at the plane and insisted on hiking with her even though he was the most boring fucking person she'd ever met in her whole life, the whole time he'd been telling these horrible stories about what was happening in M group since the alpha disappeared. Stories that would make Brian feel thrilled, she couldn't help thinking with more than a little resentment. He'd practically be cumming in his pants! The way that Roger described it sounded like some nightmare vision of what Brian called the "violence gene" on steroids. His whole theory was that the most violent males were also the most successful at passing on their genes. And so over tens of millions of years primate societies had evolved to be reward male aggression, and that's why humans are the way they are too, like it or not. Everything that Roger was telling her about all the tension and fighting and fucking and even killing between the male chimps and the female chimps in M group in the last week seemed to confirm that nightmare and she didn't want to hear any of it. She felt like crying. She felt like an idiot for thinking that she might be able to see something that no one else who studied chimps had ever seen before, and that proved everyone else wrong. And even more than that, strangely, considering that it didn't fucking matter one bit in the grand scheme of things, even more than that she was pissed at herself for acting like a pathetic schoolgirl around Chad. What the fuck was she doing? Maneuvering to get close to him and let him get nice looks at her butt and her tits while they were packing the gear this morning, in the outfit she'd picked out in part because it was a good outfit for hiking and swimming and working in, but also because she thought he'd like it too. She told herself that it was more "subtle" when she did it but she was really acting no differently than any of the undergrad girls, or Jess. Or even Karin who'd she'd seen showing off for Chad a little too, joking with him and finding ways to be a little closer to him than she needed to be just to get the job done. The flirting with Jess was one thing, but for Karin to do it too with Chad had really kind of hurt Kate! She couldn't blame Chad of course. Karin was beautiful, almost a younger version of Kate but with that exotic Jewish princess thing going for her with her kinky hair and her interesting nose and her olive skin. She'd probably look like a goddess in a few days with all the sun they'd been getting. And there was that moment when Chad turned toward her without knowing it and she was right behind him, enjoying his shoulders and backside on the sly, and smelling him a little, and they'd found themselves chest to chest for a second. He'd kind of recoiled away from her in embarrassment and maybe like he was a little disgusted too. And why wouldn't he be? She was his fucking professor and she was thirty-four years old and married to his other fucking professor, and she was having her period and she was overweight and she felt like a big fat cow. And now she was pissed at herself for having felt any of those things and she felt like an idiot. They'd finished their work for the day and they were all waiting for dinner. She was sitting on a towel by the lake looking out at it while the undergrads and Jess played some game with a soccer ball in the water that was really just an excuse to splash each other and flirt with each other and grope each other's half naked bodies. And Karin was lying next to her in her blue polka dot bikini and she looked so hot and young in her thirty-year old tennis player body that Kate felt like murdering her. And Jess was wearing a hot red bikini top that barely covered her perfect tits and a thong bottom that showed off her absolutely perfect ass. And Kate wanted to murder her too. But Chad clearly wanted to mount her as soon as possible. He was like a fly on shit around her and so were the other two guys too, like adolescent chimps hanging around the swollen pink rump of a mature female in heat. There was one point in the game where Chad turned around suddenly and found himself chest to chest with Jess, though he was so much taller than her that her tits were more at his stomach level. He'd kind of pretended to lose his balance in really the most adorable way and ended up hugging Jess to keep from falling over and then pulling her down in the water on top of him while she laughed and pushed her tits together for him, practically right in his face. The game ended and Jess came jogging up toward Kate and Karin where she'd left her towel. Kate eyed her up and down as she dried herself off, with as much displeasure and contempt as she could show, and Jess noticed eventually and looked uncomfortable and a little surprised and hurt. Kate tore into her. "Look. If you're going to fuck him, then fuck him. I know I said you couldn't but honestly it would be better if you fucked him in private in your bedroom every night for the rest of the trip than to flirt with him like a fucking teenager in front of the other kids. It's going to fuck up the chain of command and then we're not going to be able to do our work. And I'm here to work and I thought you were too." Jess and Karin were eyeing each other warily, rooted to the spot. Advanced Primatology Ch. 04 "It's fine if you fuck him if you do it discretely and if you enjoy it and if it helps you do your work. But if you're going to be flirting with him all day half naked with all the other kids watching then I don't know what to tell you. It just doesn't seem like you're very serious about what we're trying to accomplish out here." "Jesus Kate, I get it, okay. I'm sorry. I get it." Kate sighed and rolled her eyes. She felt bad now. "Look, I'm sorry too, okay? It's just that Roger the fucking boring guy was just telling me all these nightmare stories about the chimps and I'm nervous that we're not going to get the results we wanted and it's stressing me out. Sorry. But I mean it: you can have sex with Chad. I understand. You can do whatever you need to at night to make sure you're at your best for the next day. I respect that." Kate stood up and unbuttoned her white linen shirt and then slid it off her shoulders. She'd taken the yoga pants off when she first got back from her hike. She stood there in front of Karin and Jess looking every inch the alpha woman in her black swimsuit and her full, ripe body. "Really, Jess, it's fine. No judgment. I think it's great, actually. Just make sure to use protection. And try to keep it down. We're all sharing one cottage, and Karin and I need our sleep." She turned her back on them and walked straight down the grassy slope to the lake, noticing that most of the undergrads had kind of stopped what they were doing and were trying to watch her without getting caught. Chad was pretending to ignore her but she knew he'd seen her, and she could tell he liked what he saw. And that other guy, Kevin, was looking right at her, and she noticed that he was kind of cute in his own way with his rail thin body and his adam's apple and his long bangs over his deep-set eyes. She looked right back at him and gave him a quick up and down in his long loose swim trunks that were riding down at his hips and showing off his ripped abs, which surprised her. She flashed him a friendly smile, nothing dirty, then looked to see how the other kids had reacted. Chad was staring at her full on now and she suddenly remembered herself, how hot she looked in the low-cut suit that showed off her curves. Yeah, that got his attention, she smiled to herself. Then she dove into the water and started swimming and she didn't stop until everyone else had gone to dinner. Part 4: Chad knew he was going to fuck her as soon as dinner ended and the music started. Someone had an i-phone and speakers and they'd taken them down to the little beach by the lake with some beers for a little party, just the undergrads and Jess. She grabbed him as soon as they got down there and started to grind on his leg, looking amazing in the pale moonlight with the stars reflecting off the lake and the three-quarter moon still low and big in the sky. Jess grabbed the back of his head and put her mouth to his ear. She told him that she was going to leave now and in five minutes he was going to leave too and come to her room and she'd be waiting for him. She sauntered away in her pink bike shorts with the tribal pattern that barely covered her perfect ass. Waste not want not, thought Chad, as he smiled to himself and decided to put the five minutes to good use. He caught sight of Karin dancing a few feet away from him with that other guy Kevin. Now that Jess was gone Karin was definitely the finest piece of ass at the party and Chad was impressed again. This Kevin guy was turning out to be a little bit of a player. Game on, thought Chad, as Karin turned away from him toward Kevin, smiling and having a nice time. Chad kind of eased up behind her like it was all a big joke, pretending to grind her a little and smiling and laughing while making sure to stay far enough away from her that she wouldn't mind too much. She turned toward him again and smiled and laughed and kind of shimmied her shoulders a little in the silky low cut v-neck she was wearing with her blue bike shirts that showed off her legs and her hips and even her crotch when she shook it. "I'm finally getting that dance with my favorite TA," he smiled at her sweetly. She rolled her eyes, clearly a little buzzed, and then turned around again. Then she surprised him. She kind of bent forward at the waist and stuck her ass out toward him and then backed it right up into him, smiling the whole time like she thought it was a joke too. Then she stood straight up again and reached back and grabbed the back of his head and started to grind against him a little, slowly, just once or twice. Then she turned to face him and now her crotch was grinding against his leg and her tits were against his chest. They felt amazing, heavy and full. "You better get going, tiger, you don't want to keep Jess waiting," she teased him. Then she turned and started dancing with Courtney and Ellen who were smiling at him too and laughing. Whatever. Girls were so weird. He walked the 500 feet over to the women's cottage and climbed the steps to the little porch outside it and walked straight through the front door. It had a large common room filled with laptops and files that they'd be using as an office during the evenings and each of the women had a tiny bedroom just off it. He saw the door to Kate's room and wondered if she was awake in there and if she'd be listening to him fuck Jess tonight, and if she'd like it. He felt hard and flushed and dizzy again. Then he walked straight into Jess's room and closed the door behind him. She was sitting on her bed facing him still in her pink bike shorts and her white tank top but with no bra underneath now. He took two steps toward her but then she motioned to him to stop. She leaned back and eyed him. "Glad you could make it sweetie," she smiled wickedly, "how about you take off that t-shirt for me?" Chad smiled and took off his shirt and let her look at him. He didn't have an ounce of fat on him from all the running during soccer practice and he had lean muscle all over him. He could see she was excited by it. He probably looked a little different than her grad student boyfriend, a chemist or something, a "real sweetie." "Am I just here for the strip tease or do I get to fuck you tonight" he asked. Jess laughed. "I haven't decided yet. First I have to examine you. Now turn around and pull the shorts down." Chad smiled and did as he was told, grabbing the waistband and sliding the shorts slowly off his ass. "Dios Santo!" he heard from behind him. "Now take them off." Chad did it. This was getting interesting. "So I'm guessing Professor Morgan said you still couldn't fuck me," he drawled. "Is that why I'm way over here and you're way over there?" "No, actually. She gave me her permission, sweetie. She said she wanted me to. She said if I was a good worker then I could fuck you as much as I wanted for the whole trip." Chad couldn't tell if she was serious or not (probably not) but he loved it anyway. He'd been hard before but now his cock was starting to launch off him again in that way it did whenever he thought of Kate and sex. He turned around to face Jess. "I didn't tell you to do that," she snapped playfully. Then she took a long look at him. "Come here," she said. Chad stepped forward slowly until he got so close he could feel her breath on his stomach. She took a good close look at his cock and balls. Then she took her palm and started to rub his balls hard and then she rubbed the whole length of his shaft, pinning it back against his stomach and holding it there. Then she leaned forward and put her nose against his balls and took a deep breath and sighed. She moved her hands to his ass and groped it and his cock sprang forward and it was sticking right in her face. "So do I get to fuck you?" "I don't know," she teased. "Did team leader bring the right gear this time?" He gave her his sweet smile. "Yeah, it's in my shorts. Should I go get it?" "Not yet sweetie. No rush." She took his cock in her hand and started to stroke it while she looked up at him with her big brown eyes. She started slowly but pretty soon she was jerking it hard and fast and her tits were jiggling and she was fingering his ass. He reached down and grabbed the bottom of her tank top and started to pull it off. She looked up at him again and rolled her eyes. "Typical boy. Let me guess. You want Professor Jess to show you her titties?" He nodded. She rolled her eyes again and laughed. She sat up straight for him and grabbed the bottom of the tank top and peeled it right off. Holy Christ. They were so firm and round and turned up at the ends that he couldn't believe they were real. He reached down and cupped them, weighing them in his hands and bouncing them a little. He moved his thumbs to the nipples. Jess squirmed away from him. "That's enough for you," she scolded. She took his cock in her hand again and looked up at him. Then she opened her mouth and swallowed him and started to move her head back and forth, slowly, still looking at him. "Yummy," she sighed, pulling off him for a second, "I think I'll just blow you for now and we can save that condom for later. Okay sweetie?" He nodded. She swallowed him again and wrapped her lips tightly around him and started to suck him again, almost riding him with her mouth. Christ she was good at this. He'd never felt anything like it. He puts his hands on his hips and tried to relax. He had a plan. He wanted to cum hard and fast for her right now to break the tension and maybe get Jess's guard down a little. She'd be relaxed and pleased with herself then and she'd want to get off too. Then it would be easy to get the bike shorts off and get in bed with her naked and probably fall asleep in each other's arms. He'd let her rest for a while and then wake her up with a hard naked shaft right at her opening and just take it from there. Jess had both hands spread flat against his stomach now and her nails digging into the bottom of his chest and she was sucking him long and fast and hard. Chad could tell that she couldn't believe how hard his body was and how hard his dick was too. He had his hands in her hair and was moving his pelvis along with her and moaning and drawling her name. "Awwwww Jess, you're killing me," She really was. This was a woman not a girl. And she was a woman who had obviously sucked a lot of cock in her time and who really enjoyed it. He knew she was going to be an absolute firecracker when he got his cock up inside her, and the way things were developing he might even get to fuck her raw tonight. She put her hands on his ass cheeks and spread them wide and then put a finger to his anus and started to circle it hard. She took his cock out of her mouth and stroked it and looked up at him. "You gonna come for me now sweetie? You gonna come for professor?" She put her lips to his balls and started to kiss them and massage them with her tongue while she stroked him hard. He was right on the edge already. He could hardly believe it. And then she did something fantastic that he'd only felt a couple of times before. She stuck her finger in his ass, pretty deep actually, and suddenly, and that really did it for him. He came hard and long while she kept right on stroking him. He was cumming all over the place and groaning and when he finally came to his senses she was sitting there laughing and shaking her hands with his sperm hanging in thick drops from her face and breasts. She looked gorgeous. He grabbed his t-shirt from the floor and sat down on the bed next to her and laughed and apologized while he cleaned her off. Then they kissed passionately and he laid her down on the bed next to him and slid off her bike shirts. Five minutes later he had his head between her legs and she was pulling his hair and calling out his name loud enough for Kate to hear for sure, while she rode the edge of a big orgasm. He was rock hard again. He knew what she liked. He took her ass in his hands and pulled it up off the mattress while he tongued her clit and stuck his finger in her anus to return the favor. "O Chad, yeah baby," she started shaking and gasping and bucking her hips and she didn't stop for four full seconds. When she did stop he moved up behind her and spooned her with his hard cock up against her while they fell asleep. A half hour later Chad had his cock between her thighs and his hands on her tits while he kissed her neck. She woke up a little and started to grind her ass against him. "Feels nice," she said. "Yeah? Not too sleepy?" She shook her head. She grabbed the back of his head like Karin had done at the party earlier and started to grind him harder while he pinched her nipples and moved his hips along with her. She was soaking wet already and it felt warm and velvety against his hard shaft. He kissed her neck and moved one hand to her stomach and her pubic hair while he put his mouth to her ear. "Can I fuck you a little sleepyhead? Should I get the condom now?" "No, I mean yes, I mean, I don't know sweetie." "What don't you know?" "I don't know if I want the condom. I hate those things. I should never have gone off the pill." Chad was maybe harder than he'd ever been in his life and his heart was pounding against his chest. Why? He'd fucked dozens of girls bareback and shot his load inside them. So why was this so much hotter? Was it just because she was older and her body was fuller and riper and she wasn't using any birth control? And why shouldn't that be hotter? Wouldn't that make sense? That he was hotter for her because it made sense for her to be the one to implant with his seed. She was stronger and more determined and more experienced than Elise, or Courtney or Ellen and she'd be a better mother for his baby (which he didn't want to have) and a better mate to mix his genes with. So he'd been programmed by evolution to get harder for her and to cum harder for her too. He had his fingers on her clit now and she was riding them while he angled the tip of his cock so it was right up against her opening. He had his other hand spread flat against her sweaty chest as he rubbed it hard. "I hate them too. I can never stay hard in them." He changed the angle of his cock so he could run the whole length of it against her wet lips, letting her feel it. "That would be a shame," she teased. "Poor sweetie." She grabbed his cock by the base and angled it toward her slit. "Just go slow okay sweetie? And try not to cum all over me this time. Use your shirt or something. Okay?" He nodded. She eased back and she was so wet she took almost the whole length of him inside her in one try. He could tell she loved it. "O my god, o my god, so big, go slow." He did as we he was told. She felt amazing. She was soaking wet but her wetness felt different and better than any girl he'd ever been inside before and it just felt amazing around his cock. And when she ground back against him slowly and tilted her pelvis he was pretty sure that the tip of his cock was against her cervix and it felt soft and warm. He'd done a lot of internet research about signs of fertility and he was pretty sure these were some of them. He wanted it to last all night but he could tell he wasn't going to. He'd lost track of time but they'd been fucking for maybe five minutes like this, slowly, and he was already right on the edge. Christ what was wrong with him tonight. He was like a fifteen year old with his quick trigger. And Jess was already on the edge too. She was quaking a little now and making the sexiest and longest moans he'd ever heard, over and over, while she bucked her hips and rode him a little harder "Ooooooohhh oooooohhhhh oooooooohhhh." She was cumming for sure but it was different than any girl he'd ever felt cum on his shaft before and it just kept going and going. It was like her whole body was cumming and then he felt something that blew his mind. She changed the angle of her pelvis and suddenly it was like her cervix tipped upward or something and a whole new part of her just opened up to him and she started shaking harder. And the walls of her pussy seemed like they were contracting around him and pulling him into her and holding him there while she bucked her hips harder. "Ohhhhh ooohhhh ooooohhhhh. Be careful baby." Chad was right on the edge and he didn't know what to do. She'd told him not cum inside her but he wanted to cum inside her more than anything in the universe. But he also wanted to fuck her again tomorrow night and the next night and if he came inside her now she would be pissed and maybe she wouldn't let him fuck her again right away. "Ooohhhh ooooohhhh ooooohhhh." While his mind was thinking his body was getting ready to do what it wanted. It took everything he had to pull out of her at the last instant and grab his t-shit and hold it to his cock while he came and came so hard he nearly passed out from the rush of it. "Thank you sweetie. That was amazing. Tomorrow I won't be so sleepy and I'll fuck you hard, okay?" He spooned up behind her and they went to sleep. Part 5 It had been a terrible night for Kate, maybe the worst of her life. Now she was up early to do yoga and try to clear her head for the day's work. She had so much riding on this trip and she needed to put everything else out of her mind except the chimps in group M, and where they were and what they were doing. She'd figure everything else out later. She hadn't gotten off to Chad last night because she was still a little hurt and jealous by all his flirting with Jess and Karin, and still a little pissed at herself for feeling that way. And she couldn't hear him and feel him through the walls like back at the hotel anyway. So she'd opened her laptop and put on her headphones and looked at some more of the videos on Brian's flash drive. The more of them she opened she more upset she felt and the more dread. It almost made her nauseous. It wasn't that most of them were about male professors having sex with their students. She didn't mind that. It was that most of the videos starred the same actress, the little blonde one with the small, perky breasts and the pony tail and the upturned nose that made her look a little snobby, a little superior. Brian really liked her. And she looked a lot like Elise. She knew what she was going to find long before she actually opened the folder titled "pics." She'd known it for months, actually, without realizing. She clicked on the folder and then clicked on the first of many files and she wasn't surprised at all. It was Elise on her knees naked looking up at the camera and smiling mischievously with Brian's hard dick in her hand and his cum all over her face and chest. Part 6 Chad woke up at the break of dawn feeling refreshed and energized. He got up and got dressed and walked back to the guys' bunkhouse where his gear was and looked through it quietly so he wouldn't wake up Kevin (who was in bed with Ellen he noticed) or the other guy. He found his speedo and slipped it on and then walked down to the lake. He wanted to have a quick swim to clear his head before their first hike to see the chimps today. He'd had a great night, maybe the best ever. He felt close to Jess and maybe even a little in love with her. But then he saw something that made it all disappear. Kate was up early too and she was doing yoga by the lake while the sun came up in front of them. She was in downward dog in a pair of black bikini bottoms that showed him all of her incredible ass and her long legs, and a little half t shirt that was hanging loose around her and riding up her chest so her breasts were practically spilling out of it. He stood there and enjoyed her for a while and then she opened her eyes. She was looking straight at him upside down through the little gap between her legs. He couldn't tell exactly, but he was pretty sure she gave him a good long look, down and up, lingering a little on his package in the tight speedo. Advanced Primatology Ch. 04 Then she closed her eyes again. Chad strode down to the lake and dove in and swam straight out toward the center where the water got colder and deeper. Advanced Primatology Ch. 05 Part 1 After breakfast with the rest of the undergrads in their little mess hall Chad and Elise walked over to the lawn in front of the women's cottage that was going to be the staging area for their first day in the field. Chad was jumpy with excitement. They would be splitting into three groups, each led by one of the women, and each group would follow one of the three main paths that the chimps in Group M used to forage for food and patrol the borders of their territory this time of year, now that the rainy season was ending and the long dry season was about to begin. As undergrad team leaders Chad and Elise had to make sure that the gear was packed properly so that each group had enough water and food and emergency supplies to make sure that everyone got back safe and sound (it was no joke out there from the way Karin and Jess described it) and that the cameras and microphones and such were charged and in good working order. Elise looked cute in the little "safari" outfit she'd picked out for the first day of fieldwork. Khaki pants cut mid-calf and stretched snug over her slim hips and her tight little runner's ass. Hiking boots. Tar Heels baseball hat. A light blue t-shirt hugged her perky little tits. God I love girls, Chad thought to himself. The way they dressed for him and displayed their bodies for him. He felt like putting Elise over his knee right then and there and pulling down those cute little khakis and fingering her to orgasm right there in the open. She saw him eyeing her. "What's the matter, stud, Jess didn't take care of you last night?" Chad cocked his head and squinted like he didn't know what she was talking about. "O don't play dumb, the whole group knows about it. Karin got pretty buzzed last night and told us everything. How Professor Morgan gave Jess permission to use little Chad here as her personal fuck toy for the rest of the trip if that would keep her happy and make her a good worker!" Chad was annoyed at Elise but he was also dying of curiosity. Had Kate really said that? He was getting hard now just at the idea of it, that Kate had given him to Jess as some kind of sexual reward or something. "Well, did the little fuck toy do a good job last night?" "I think you know," Chad drawled in his best hillbilly accent, laying it on thick. "O I do know!" said Elise, her eyes flashing at him mischievously. "And I miss it, to be honest." She stopped suddenly and turned toward him and stopped him in his tracks. She came right up to him and put her hands on his balls and squeezed them a little as she pressed her tits against him. She put her nose to his neck and inhaled deeply. "Ahhhhh. I do like your scent. I tell you what, stud, come to the girl's bunkhouse tonight and I'll make it worth your while. I'll let you fuck me right there in the middle of the room on the floor with all the girls watching, and when I'm good and finished you can have any of them you want." Chad laughed and shook his head. "Sounds fun. But I don't think I could handle the pressure." "O I think you could. And I want you to. I want you to be MY fuck toy on this trip and I'll do whatever you want to get what I want. "O yeah? Like what?" Elise smiled at him and rubbed his shaft a little through his jean shorts. She looked like she definitely thought she had his number, knew which buttons to push. "Like maybe I'd let you fuck me raw and cum inside me. Would you like that? Maybe I'd let all the girls watch you do that to me, and see how hot it made me, so they'd want to try it too. Maybe you'd get to come inside all of us, if you're up to it." Jess came outside onto the porch and saw Elise pressed up against Chad and fondling him and flirting with him. She laughed and rolled her eyes and walked down the steps toward them to inspect the gear. She was wearing her own little safari outfit that was carefully selected to protect her from thorns and insect bites, sure, but also to display her ass and breasts for Chad's own personal pleasure. It was pretty much the same as Elise's outfit. The pants were identical actually (girls were so weird!) except Jess's ass was practically bursting out of hers, and when she bent down to open her camera bag where it lay on the ground Chad caught sight of her bright red thong. His cock was completely hard now. He pulled his t-shirt down over it. He looked down at Elise. "Sounds interesting. Can I have a rain check on that? Maybe for tomorrow?" Elise stomped hard on his foot and turned and walked away. She wiggled her ass for him though, clearly enjoying herself and her little game. Chad looked up and saw Kate at the top of the stairs now, stretching her arms over her head as she gazed out at the blue expanse of lake Tanganyika. She looked tired and sad maybe but also somehow otherworldly, like her mind was already in the forest with the chimps and everything happening around her right now was just a means to an end to get her where she really wanted to be. She was wearing the same outfit as yesterday except she had on a UNC baseball hat too and it made her look younger (not that she was old!) and more approachable somehow. She didn't have her glasses on either. He looked carefully at the sheer white button-down shirt and noticed that she was wearing a bikini underneath it today and that it was light blue and it had a little underwire support that made her breasts stick up a little higher. She looked phenomenal at the moment, stretching her long arms above her and arching her back so that her breasts pushed straight out at him. She opened her eyes and caught him looking at her, not for the first time today. She flashed him a friendly smile and looked him up and down again, like she had earlier that morning when he'd been watching her ass while she did yoga. He knew he looked good in his UNC soccer t-shirt and his skinny jeans cut off at the knees. He had on his speedo underneath. If he knew anything about anything in the wide world he knew that he definitely wanted to be there when she slid that white shirt off her shoulders sometime later today, after the work was done, and jumped into a swimming hole somewhere. He remembered the photo of her in the string bikini in Puerto Rico from her husband's Flickr page, with her large breasts wet and glistening as she smiled shyly at the camera. He thought carefully about how to arrange things so he'd end up in her group today. Part 2 Kate's emotions were strange. On one level she felt abysmal, truly abject. She felt like she'd been kicked in the stomach by that picture on her husband's flash drive: Elise with her husband's dick in her hand and his cum on her face and that smug smile on it too. She felt like she was going to throw up. And she was beyond tired from not having slept all night. But on another level she also felt weirdly dispassionate about the whole thing, almost objective. It made sense. It wasn't about her. In Brian's mind he was an alpha male, always had been, ever since she knew him and he sweet talked his way into her bed and between her legs when she was nineteen and he was her brilliant, unbelievably hot TA with the hot soccer body and the deep tan. And now he was pushing forty and he was about to make a baby with his wife and things were getting very serious. And he had tenure and a world famous book and dozens of little nineteen year olds still ready to suck his cock for him and to ride it for him if he showed even the slightest interest in them. It wasn't that she forgave him. She didn't. She didn't know if she ever would. But she understood how it was almost inevitable given the way that he thought of himself, and thought about his masculinity, given how it would make him feel to be at the pinnacle of his fame and power, and maybe even to fear that he'd start losing that soon. What a shithead! Men were such boys. She'd given her laptop to Roger's wife Alex that morning and asked her to take it to the village with her today when she went to do her errands. She asked her to go to the little internet café and send the email she'd written and then to go back when she was done with her errands and check her email again to see if her husband had replied. Alex was boring like Roger, but sweet too. Kate felt like she could trust her. Her email to Brian was simple: "I know about Elise. I saw the flash drive. Don't contact me and don't come here. If you do I will leave you. I will call next week as planned." She knew he'd write back anyway and in a way she wanted him to. But she didn't want him to come. She was afraid of what she might do to him, and she needed to focus on her work now. Kate looked up at the green slope above her. They'd been hiking for almost an hour and they were almost to the forest line. She could feel the air starting to get cooler and she caught the heavy scent of wet leaves, and flowers, and fruit. Courtney and Kevin were behind her and Chad was in front of her. For the last hour she'd been watching his butt muscles work hard in the tight jean shorts he was wearing and she'd been kind of enjoying herself to tell the truth. It had been a hard night and she needed to find her pleasure where she could. And Chad's nineteen-year-old ass was like a soothing dream. Suddenly she had a crazy idea to order him to stop right where he was. She wanted to walk up behind him and unzip his jean shorts and pull them down and stick her face in his crotch and take a deep whiff of him. That's what a bonobo matriarch would do, if one of her favorite older males had copulated with a younger female who wasn't part of the main clique. She'd walk straight over to the hottest, youngest male she could find and inspect his hair and his underarms and his penis. And if she liked what she saw she'd fuck him hard and raw, face to face with her tongue in his mouth, right there in front of the whole group while she screamed out her pleasure. Then she'd lay with her head in his lap and let him groom her the whole rest of the day. That's what a bonobo would do. And Kate had always considered herself part bonobo. It was sweet the way Chad had pretended to end up in her group by accident this morning, assigning everyone else to Jess and Karin and then acting surprised when that left him with her group. She appreciated it, actually. She wasn't going to fall apart because Brian had been fucking Elise for god knows how long, and god knows how many other girls too. She'd thrown his flash drive into the lake this morning because she didn't want to know and it didn't fucking matter anyway. She was still going to do the work she'd come here to do. But she was also hurting. And it felt good that Chad wanted to be around her, even if it was just to learn from her about chimps and sex. Even if he didn't want her body too, which she was pretty sure he did. She'd seen the way he looked at her this morning, on the beach and on the porch. She admired his ass again in the jeans as he climbed the slope in front of her. She was looking forward to finding a cool swimming hole somewhere after lunch and stripping down to her bikini for him, and watching him strip down for her, and then slipping into the water with him and flirting with him a little, making him want her. That would feel good. They reached the forest line and hiked for another thirty minutes and then they found some chimps from group M on a wide flat rock beneath a late-blooming fig tree. Kate motioned for everyone to squat down and avoid eye contact like she'd taught them in the orientation sessions. The chimps were habituated to people but they were still no joke if you made them feel angry or threatened. She'd been charged by them before, teeth bared and shrieking. She took out her little note pad and her binoculars and everything else around her except the chimps just disappeared. She was in her element, her natural state. She did not exactly like what she was seeing as she studied the chimps carefully. In her heart of hearts she wished they were bonobos instead. She didn't really even like chimps. But she also felt strangely removed from what was happening with the apes. Gone was all the competitive fire she usually felt at times like this, that burning passion to show the world, and to show Brian, that she could see something that no one else could. What she felt instead was a strange sense of calm and sadness. This wasn't about her, or about what she wanted to see. It was about these beautiful animals, so closely related to her, and yet so otherworldly. So she didn't feel any of the anger she normally felt as she watched the males dominate the females, almost terrorizing them. There were three young adult males and five females ranging from mature to pre-pubescent. The males had finished gorging themselves on the figs and now they were strutting around and challenging each other by beating branches on the rock. And they were displaying their hard penises to the females as they moved in for their turn to eat, finally. She could tell that there was no clear alpha yet who'd moved in to fill the power vacuum since the old alpha disappeared (probably murdered by a rival?) and the atmosphere was crackling with tension. She watched one of the males raise his fist to strike one of the females when she reached for a fig that was too close to a rival male. Kate could tell she'd been beaten before by him, probably recently, and she knew this meant she would be more likely to have sex with him when she came into heat, which looked liked it would happen pretty soon. She had the beginnings of her swelling already. But for now all eyes were on a beautiful young female, the "pink lady" Kate decided to call her, who was barely out of adolescence and whose sex skin was full and enflamed. It looked like her backside was on fire. She was sitting there to the side of the rock munching a handful of figs and waiting to see which of the males would end up winning the challenges and would come over to her to claim his prize and mount her. Kate lost herself in the chimps for a while and then her attention shifted to a different female who she hadn't noticed before. She was sitting off to the side quietly, surveying the scene. She was maybe thirty-five, about the same age as Kate, but unlike her she had surely given birth to many children by now and she probably had about ten more years to live. She was beautiful. She had a beautiful body. Soft and fleshy and curvy and she had big, dark expressive eyes. Mahalia. That was what Kate decided to name her, right on the spot, because she'd always loved that name and because it sounded like Mahale and because in Kate's mind this was the empress. These were her mountains. She knew that when Mahalia came into heat she would be the most popular female in the group and she would drive the males absolutely wild. Lots of research showed that young males preferred to copulate with the most mature females, who had proven their reproductive success and therefore made the best mate to mix their genes with. But for now she had only one admirer. A young adolescent male, a "teenager." He was long and lean and handsome. Brad, Kate decided to call him because he was a pretty hot young chimp, she had to admit, and it rhymed with Chad. It was probably obvious, and the other women would probably tease her about it when she told them, but she was way past caring. Brad kept fetching Mahalia figs from the high branches and handing them to her and smiling his big toothy grin and making sweet, friendly sounds. Then Kate saw something amazing. Mahalia stood up suddenly and walked straight over to Brad and looked him in the eye and then squatted down on her haunches in front of him and reached for his penis. She tweaked it a little so it got hard and red and then she inspected it all around from every angle. She seemed fascinated by it. Then she stood up and went back to her figs. Brad looked flushed and dazed, standing and swaying a little like he was a tree that had just been cut down and was about to fall over. Kate looked over her shoulder to see if the kids were watching and she saw Chad behind her with the camera out shooting a video. Good boy, she thought. She smiled and gave him a big thumbs up. She was happy to have a recording of the interaction to study later that evening back at the cottage. There was definitely something interesting going on with these two. She stood up and walked straight over to Chad, swinging her hips, and noticed that he was blushing a little and looking down at his feet like she'd just caught him watching porn or something. It HAD been pretty steamy. She laughed and blushed too. They hiked back down the mountain and stopped at a good swimming hole and ate lunch. Then the four of them stretched out on a grassy slope near the little pool and Kate almost fell asleep. She was exhausted. She could hear Courtney and Kevin chatting and flirting next to her and at some point she heard them get up and wander off into the forest. Penis inspection time, Kate thought to herself. She liked Courtney. She would make a good bonobo. She wished she could fire Elise's ass and make Courtney the new undergrad team leader. But that would raise suspicions. She noticed that Courtney had cut her hair short sometime in the last couple of days and it really looked good on her with her full, strong body and her handsome jaw. She was glad that she was letting Kevin get a little of that sweet backside of hers. That would be good for him, and for group morale. Good girl, she thought to herself. She turned on her side and looked at Chad, stretched out on the grass with his t-shirt riding up and his flat stomach exposed. He had his forearm over his eyes to shield them from the midday sun and it showed off his lean bicep and his underarm. She could smell him and she liked it. She poked him in the ribs. He turned on his side toward her and smiled. "So why didn't go with Jess's group today, huh tiger? From the sound of it you guys had a pretty good time last night." Chad eyed her uncertainly. "Uh, sorry about that. Jess said you were fine with it." "It's okay. I am fine with it. I think it's great actually. You two have a lot in common. You're both smart and young and like to have a good time. But you have to keep it between us okay? I could get in real trouble if anyone at the college found out. She is your teacher, technically." "Don't worry. Believe me, I'm not going to complain!" They both laughed and turned a little red. "So why aren't you with Jess today?" She had her head propped up on her elbow and she was nibbling on the end of a long spear of grass. She let her eyes wander down the whole length of him, taking in his hard body. She knew he noticed but she didn't care. She was enjoying herself. "Well, I mean, Jess is really hot and everything. And it's flattering that she's attracted to me. And yeah we did have a great time last night. But that's not what I'm here for. And not to be an egomaniac or anything but it's not that surprising either. People have always wanted me for my physical talents, for what I could do with my feet to a soccer ball, or what I could do with other parts of my body." He rolled his eyes at Kate adorably and blushed. She felt a little bad now for perving on him all morning. She raised her own eyes from his flat stomach to meet his deep blue stare. "What ARE you here for?" "I'm here for the chimps," he shot back right away. "I'm here to learn. And you know the most about the chimps so I wanted to be with you today." Kate smiled at him, almost beaming. She really liked this kid. He was sweet and smart and he was comfortable opening up to an older woman and talking with her, being intimate. He'd been raised by a single mom with a drinking problem (hadn't Karin told her that?) so it all made sense. He'd probably been a real confidant for her, a real support. Advanced Primatology Ch. 05 "So what did you think of Mahalia and Brad?" she asked him. "Who?" "The curvy older female and the skinny young male. Don't play dumb. I saw you watching that penis inspection. So what did you think?" "I thought it was hot!" Chad blurted out, surprising both of them. They both laughed and turned red again. "No, but seriously," he continued, "I thought it was really interesting. I thought maybe she was about to come into estrus and she was hunting around for the best tool she could find to pleasure herself with. Something like that." "I'm impressed," replied Kate. "That's what I thought too. We'll have to check Roger's field notes when we get back to the cottage tonight. That will tell us about Mahalia's cycle and when she'll ovulate next. My guess is that it will be soon, in the next week or so, and that Brad is playing the long game. He's trying to bond with her while the other males are distracted by that young hot female with the pink backside. Then he'll try to get her somewhere alone with him away from the group when she comes into estrus so he can have sex with her exclusively the whole time she's fertile." "Sly dog!" said Chad. It all made sense now. "Sly dog!" Kate nodded and laughed. She was really enjoying herself. It had been a while since she talked with someone about apes like this, casual and relaxed with a man she found attractive, or with a male anyway. She thought of her husband and felt nauseous again. "So what did you think of Brian's class. Is he a good professor?" "Professor Phare? O my god that class was the best! He's really inspiring, and, you know, he just has this amazing perspective on human behavior and on sex and reproduction and stuff." "Yeah I know," Kate rolled her eyes at him and sighed. "Yeah, it was a terrific class. And then he told me to take your class and that was amazing too. You guys have changed my life, actually. I've always thought I was smart but now I think I could actually do something else beside play soccer and chase girls for the rest of my life. Maybe I'll even go to graduate school for Primatology." "You could. You definitely have the talent." Chad beamed at her. "Thanks. That means a lot to me. I know it sounds crazy but, well, I never knew my dad, and, ever since I took Professor Phare's class I've kind of thought of him as, well, family. Not that he's my dad or anything, but that he's like my cool uncle or something." Kate laughed. "Uncle Brian, huh? I guess that makes me Aunt Kate?" Chad laughed too. Kate stood up and watched Chad carefully as his eyes travelled up her long bare legs. She'd taken her yoga pants off after lunch and she was wearing just the blue bikini bottom now. She took off her Tar Heels baseball hat and let her long auburn hair spill down over her shoulders. "Well, Aunt Kate needs to cool off now. Are you coming in?" She smiled at him and held his eyes as she unbuttoned the white linen shirt slowly and then slipped it off her shoulders, jutting her full breasts at him as she pulled it off. She looked down and admired her taut stomach, fleshy in the right places, but with a six pack from all her yoga every morning. She tried to imagine how her breasts looked to Chad in the blue bikini top with the underwire support that made them stick up a little higher. She knew she looked hot. She could practically see Chad's heart beating faster and his breath getting shorter. She turned and walked slowly down the grassy slope, swishing her ass for him, and then dove in the water. She swam out to the center of the pool and then turned and looked back at him, treading water, her long white legs spreading toward him and working to keep her afloat, and the tops of her milky breasts visible just below the surface of the water. "You have to come in! It feels amazing." Chad stood up and peeled off his t-shirt and then unzipped his jean shorts and slid them off his hips. He was wearing his speedo, Kate was pleased to see. He walked slowly down the slope toward her, almost sauntering, and then dove straight in and swam out toward her. They treaded water near each other for a few minutes, facing each other, and made small talk about the lodge and about school. Then Courtney and Kevin came out of the forest looking calm and refreshed and they all got dressed and grabbed their backpacks and started the long hike back home. Part 3 The first thing Chad did when he got back to the lodge was to find Jess and grab her by the wrist and pull her straight back to the women's cottage and to her tiny bedroom. He was crazed with lust from all the flirting with Kate and he needed to fuck Jess hard now. "What are you doing sweetie? It's dinner time and I'm hungry." "You can eat later. And I'm not your sweetie." As soon as he got her to her room he ripped off everything she was wearing and pushed her back naked on the bed with her legs splayed. Then he stood at the foot of the bed and undressed for her while she watched him. He knew she liked that. Then he dove onto the bed and laid his body flat over hers while he held her head in his big hands. They kissed wildly, their eyes locked together as their tongues danced in each other's mouths. Jess brought her hands to his to his face and raked his stubble with her nails. He had the beginnings of a beard now and he could tell she loved it. He grabbed the base of his cock and rubbed the tip against her pussy lips, which were soaking wet. He fed her the first few inches of his cock, then he pulled them out slowly, then he fed them to her again. She'd already crossed the mental barrier by fucking him bareback the night before and there was no question how it was going to be today: raw and hard. "O my god, Chad, you fucking stud. Your cock is so thick it's driving me crazy." "Yeah, you like it?" "I fucking love it. I fucking love it when you fuck me with your thick cock." He'd heard it all before and he knew she meant it. It was something about the way that the width of his shaft stretched them out wider than any other guy had before. It brought her clit closer to her tunnel and let his shaft rub up against it. That always got them off. And it always got him off too. "Yeah, you like it? How do you want it?" "I want it hard, baby. I want it hard and raw from your fat cock." "You sure darling? You sure you can handle that?" "I'm sure baby, fuck me hard now and make me cum. I need it." Chad grabbed her juicy ass in his big hands and lifted it up a little as he thrust hard into her, feeding her a few more inches of his shaft. He felt the tip of his cock make contact with her cervix again, warm and soft. He started to probe it gently with his bulbous head. "OOOOOOOOohhh ooooooooooh. How do you do that baby? You have to tell Jess how you do that." "With my big fat cock that's how. You like it?" "I love it, baby, you can do that to me anytime you want. You can do me any way you want with that fat cock of yours." Chad had an idea. He got on his knees between her legs and held her ass in his hands as he started to slide his first six inches into her more slowly now, in long strokes. He took one of his hands and started to circle her clit with his thumb. She was quaking now as her legs locked tightly around his waist. "OOOOOOOhhhh oooooohhh." "You like that darling? Does your boyfriend do that for you?" "No, no, keep going." "He doesn't do that for you? You still love him though, right?" "Yes, no, I mean, I don't know. I love your fat cock okay? That's all I love right now. Just shut up and fuck me with it." Chad smiled complacently and did as he was told, feeding it to her long and slow as her whole body shivered around it. Her fluids were pouring out of her and down the base of his cock toward his balls and dripping down on the mattress. They made a puddle beneath him as he fucked her long and slow and the minutes rolled by. Her tits were shaking and her nipples were rock hard as she looked straight at him, wantonly, her legs wrapped tightly around his waist and riding along with him, letting him set the rhythm. "This is your pussy now, okay stud, this is your pussy just for you." "Okay darling. I'll take good care of it." He pushed her back down on the mattress and laid his whole body on top of hers and started to fuck her harder, taking her head in his big hands again and kissing her full on the mouth and whispering into it, drawling. "Can I do what I want with my pussy?" He pulled her eyelids open with his thumbs and looked at her. Her eyes were practically rolling back in her head now. "Oooooooh oooooooooh." "Can I do what I want with my pussy? Can I fill it up? Can I come inside it with my big fat cock?" "Ooooooh ooooooh ooooooh." Jess was gasping and nodding and digging her heels into his ass and urging him on while she raked his back with her nails. Chad got on his knees again and took her fleshy ass in his hands and started pumping her as hard and deep as he could. He felt her cervix make contact with his soft tip and he felt it do that thing again where it tilted upward and a new part of her tunnel opened up to him all of the sudden. It felt unbelievable. The walls of her pussy were contracting around him like a warm, wet hand, milking his shaft, like her pussy had a mind of its own and wanted to drain his balls empty. He thrust into her hard over and over and then everything went blank. He was picturing Kate treading water in front of him with her legs spread wide and her pale breasts in the blue bikini top just beneath the surface of the water. He came hard and long and as deep inside Jess as he could reach and she came long and hard with him. When they'd caught their breath they laughed and kissed for a while and Jess played with his cock until it got stiff again. "We better save this one for later, stud, I need to eat something else beside your big, fat cock now." Chad laughed. They got dressed and walked to the mess hall and ate a big, hot meal. Advanced Primatology Ch. 06 Part 1 It had been really hard not to make a move on Professor Morgan at the swimming hole yesterday. Chad was pretty sure he could have kissed her, maybe felt her tits a little. All the signals were there. All it would have taken was for him to turn over and pull her to him when they were lying on the grass, or just swim a little closer to her while they were treading water, backing her up slowly onto the shallow ledge. They wouldn't have fucked. Courtney and Kevin were too close by and Kate (Professor Morgan) would never have taken the risk. But he definitely could have made out with her and felt her tits, and maybe even felt her incredible ass. There it was again doing yoga in the black bikini bottom in downward dog. She opened her eyes and smiled at him upside down, then closed her eyes as she stepped forward into a lunge, her suit bottom riding up her crack a little. Christ she had a beautiful ass. Firm and wide and shaped just like a heart. He smiled when he remembered all that "Uncle Brian" stuff from their talk yesterday. All that stuff about how she and her husband were like family to him. It wasn't that he didn't mean it in his own way. He did. But it was also calculated to get him where he wanted to be with Kate, which was between her legs with his cock inside her while she screamed out his name. He'd made up his mind now that he wanted that. She was a little different than other females he'd pursued, he'd finally worked out, and not just because she was older and married and his professor. He needed to find ways to make her feel comfortable being close to him. And to feel that way she had to feel like she wasn't doing anything wrong. She had to feel like it was the right thing to do. She had to feel like being intimate with him, and comfortable with him physically, was just a natural extension of being the best teacher she could be. Chad had worked it out that, as messed up as it seemed, that would be the reason she decided to fuck him in the end. She would feel more and more comfortable with him, and more and more hot for him, and she would tell herself she needed to fuck him to be a good teacher. Chad was playing the long game. He remembered the waning three-quarter moon through the window of Jess's bedroom last night. Kate had her period on the full moon five days ago and in nine days it would be a new moon, a dark moon, and she would be wild with lust. That was the time to really push his luck. Until then he'd let her take the lead. It was good the way he'd opened up to her. That kind of thing was so easy for him and it always worked like a charm. He'd been raised by a single mom so he was used to talking openly with a woman who was Kate's age and it felt good when he started. And the fact that it felt wrong too just made it that much hotter. His mom was drunk a lot of the time so there weren't always the clearest boundaries between them. And sometimes when she was in rehab (which was a lot) he'd live with her younger sister, his aunt. They talked about things they probably shouldn't have, and they were very intimate with other physically when he was already a teenager, and even until he left for college. Just a little too comfortable, like an old couple cuddling on the sofa while they watched a movie and maybe he fell asleep with his head in her lap, or she fell asleep on his shoulder with his arm around her. A couple times he'd fallen asleep spooning her and once he'd woken up with a hard-on and she'd wiggled her ass against him a couple times. Chad dove into the cold water and swam straight out from shore. He smiled remembering fucking Jess hard yesterday afternoon and then twice more back in her bedroom after the evening work was done. The second time he took her from behind on all fours and the third time she got things started and rode him reverse cowgirl while they tried to keep it quiet. Not that they succeeded. She was the kind of girl who didn't like to change positions a lot. She liked to find one that felt good and just ride it wherever it took her and for however long it took. She was hands down the best fuck he'd ever had. He remembered her big ass shaking for him while she pounded on his cock and held her hair up for him so he could see her whole back, her delicate spine. He would have thought her ass was a little big for him but he'd have been dead wrong. He'd cum inside her three times yesterday and the third time hurt his balls a little. He wished he'd brought some Viagra on the trip. The football and basketball players were always popping those on weekends when the girls lined up down the hall. He and Jess had talked about the fact that he was cumming inside her as they were drifting off to sleep. Jess thought they should probably go back to condoms because she was pretty sure that when the moon changed from three quarters to half it would be a dangerous time for her. But she was almost positive she was safe right now. Chad was almost positive she was wrong and he felt a little bad about it. He really hoped she wasn't pregnant. But he wouldn't be putting on a condom with her anytime soon to make up for it, especially if her fertile days were already over. Chad sliced through the water with smooth strokes as he reviewed his plans for the day ahead. He would be in Kate's group again with Courntey, but today he would bring Ellen (instead of Kevin) and just take it from there. Part 2 Kate lunged her right foot forward between her hands, breathing in smoothly as she arched her shoulders and her chest expanded in the blue jog bra. Her face was pointed at the sun and her butt muscles were tensed in the black bikini bottom that was riding up her crack in a way she was kind of enjoying at the moment. It had been another long night and she needed to relax her body and clear her head so she'd be calm and alert when they found Mahalia and Brad again (the older female chimp and the younger male) and she got a chance to observe them. They'd have to be quick. It was one of those heavy, humid days you can still get in the "shoulder season" of early June and the group wouldn't last long in the heat. There was a storm coming in too, though Roger thought it wouldn't hit until early afternoon. She stepped her left foot next to her right and went into a deep forward bend, exhaling slowly. When Alex, the naturalist's wife, brought her laptop back from the village she told Kate there was an email from her husband but she hadn't read it. Kate thanked her and took the laptop down to the beach while everyone else went to dinner. The email was a complete and abject apology. He was so sorry. He would do anything she wanted. He would go into therapy or couples therapy or he would take a leave of absence from the university and finally get his head together. And he was sorry because he knew that finding out about his affair with Elise would really mess up her research. And he was even more sorry because he was so ecstatic at the idea of starting a family together. He would do whatever it took to make it up to her and win her back. But he respected her decision to cancel his visit and he would wait for her to call in a week. She wouldn't have expected anything less really. He was a complete and utter shithead. He was a vain, insecure little boy who let his testicles rule his world. But he was not a terrible man. Kate pushed her hands into the grass and let her hips swing back into downward dog, exhaling deeply again. She opened her eyes and saw Chad standing there watching her again, not in the speedo this time but in a longer suit that still looked great on him, riding low on his hips. She'd heard him walking up behind her down the grassy slope. She opened her big, brown eyes and just drank him down in one gulp, flashing a calm smile before she closed her eyes again and lunged her left foot forward between her hands, her butt muscles straining again as the bikini bottom rode up between her cheeks. This could work for her, this new routine, she laughed to herself. She liked to watch him swim laps in front of her while she did her sun salutations and felt that surge of energy and pleasure at the start of the day. They had a lot in common actually. They were disciplined, focused, and they both liked to take care of their bodies. She was not going to have sex with him. For one thing she was his teacher and that meant something to her, unlike Brian. It was true that he was a full-grown man, physically and sexually speaking, but psychologically he was still a kid. So while she knew that he would rock her world if she ever let him between her legs, and though she very much wanted him between them, she also knew that she needed to be careful with him. He was like a lost puppy with her at the swimming hole yesterday when he opened up about his family, like a sweet adolescent chimp fetching her ripe figs from the high branches. She knew he had a different side. She'd heard him and Jess yesterday afternoon when she'd come back to the cottage to drop off her laptop before she went to the mess hall for dinner. She heard Jess saying things to Chad that she had never heard a woman say to a man before in her whole life and that made her feel dizzy and hot and jittery all over. That she didn't love anything in the world except his fat cock and that he should just shut up and fuck her with it, and that her pussy belonged to him now. And then Chad asked if he could fill it up and she just gasped and gasped and he groaned out long and slow. And then everything went quiet. It was insane. Before Kate even knew what was happening she was on the couch with the laptop thrown next to her and her hand inside her yoga pants, slick with her juices. It felt electric. Thank god her period was over or she definitely wouldn't have been able to stop herself. She felt a little less horny now and a little more in control, but just barely. She shook her head remembering what had happened through the wall back at the hotel. When you really thought about it from a certain angle it was almost like Chad had physically torn through that wall with his voice and his powerful hips and just taken her for his own sweet pleasure. It was almost like her desire and her pleasure had just been a byproduct of what Chad and his body wanted, something that her body did almost independently of her, like an animal in response to him. She couldn't deny that she wanted to know what it would feel like to fuck him for real once or twice, or maybe more than that, in her tiny bedroom in the cottage while the insects chanted and the moon rose over the lake. She'd watched the moon for a long time last night after they'd finished going over their notes and plotting out courses for the next day. The moon had been full back at the hotel but now it was more like three quarters and it looked like a sideways, deflated soccer ball. Waning gibbous she thought it was called. She remembered that she'd gotten her period on the full moon and she wondered if that was just a coincidence this time or if she always did that. She didn't pay close attention to these things, but maybe she should. Maybe it would make her a better scientist. Help her understand the chimps. She'd been noticing signs that maybe Jess was ovulating right now and that was part of the reason she had insisted she use protection with Chad, which it didn't sound like she was. She'd noticed that Jess's voice was more musical and more attractive these days, even to Kate, and that she smelled more enticing somehow. She'd been wearing a lot of tight clothes and bright colors, even by her standards, and being more wild and flirty with all the kids, not just with Chad. Maybe that was the reason Chad was so irresistibly attracted to Jess right now. Why he was so hot to fuck her that he couldn't even wait for dinner when they got back from fieldwork yesterday and he'd just grabbed her in front of everyone and dragged her after him. And maybe it was why Jess couldn't stop herself, if she even wanted to. If it even meant anything to her that she had crossed that line. Fucking someone else beside her sweet boyfriend. Betraying him like that for a hot fuck with a hot young guy who came on sweet and then hard. Then doing it again and again in the last 48 hours. Isn't that what Brian was always saying on the lecture circuit? His studies showed that women in relationships with "nice guys" were more attracted to "alpha males" when they were ovulating, even more than single girls were, and that they wanted to fuck them the most on their most fertile days. Just because it was one of Brian's theories, and just because she hated it, didn't mean it wasn't true. She'd been a scientist for long enough to know that nature didn't much care how you wanted it to be. She was not going fuck Chad. But she had every intention of enjoying herself with him. She needed someone fun and attracted to her to talk with and flirt with and keep her focused and together. But she was not going to fuck him. And she was not going to blow him or jerk him off or let him finger her or feel her tits or even make out with her. She was not going to do any of that because she was not going to give Brian that easy way out. She was not going to give him that satisfaction, if that was the right word. He had wronged her and hurt her very badly and she wanted to hurt him back and make him suffer. And maybe it would hurt him in a way if she just pushed him out of her mind and did her work during the day and had hot sex with Chad at night. If she did make out with him and let him finger her and suck her breasts and fuck her and all that other stuff. If they shared her bed. Maybe that would hurt Brian. But it would also make them even in a way. And in her mind they were most definitely not even. He had crossed a line and she wouldn't. She had her arms stretched out wide and her legs spread wide in warrior pose and she felt strong and calm. Chad had finished swimming laps and he was walking slowly up the green slope in his loose trunks. The sun was behind him and the water was dripping off him and his muscles were rippling. Part 3 They got lucky and found Brad and Mahalia after an hour of hiking. They were with the same group of chimps as yesterday beneath another late blooming fig tree. The humidity was unbearable and Kate and the kids were exhausted already and drenched with sweat. Kate settled down on her haunches and took out the binoculars and lost herself in the chimps. For the first thirty minutes or so she watched the "pink lady," the young, hot female in heat. She'd been mounted by three of the more aggressive males already. Every time two of them got involved in a challenge, beating sticks against the rocks or charging each other, the third would take the opportunity to run over and copulate with her from behind while he eyed the other two nervously. Kate got bored of the four of them and turned her attention to Brad and Mahalia. For the last hour or so she'd been watching Brad groom her patiently, almost lovingly, picking thorns and insects out of her hair and making those sweet, friendly sounds as he smiled his toothy grin. Every once in a while he would stand up and display his penis to her, hoping that she'd turn around and inspect it, but so far she hadn't shown much interest. But then maybe the fifth or sixth time she did it Mahalia finally turned around on her haunches in front of him and tweaked his penis and gave it a good, long look. Kate was pretty sure she knew what was going on in Mahalia's head. It wasn't just the size of the thing she liked, though Brad was above average for a chimp. Kate was pretty sure that she was also checking out the shape, and color, and smell and flexibility of Brad's tool to see if the was the kind of tool that would please her. She had a lot of experience, this lady, and she was so popular with the males when she was in heat that she could afford to be choosy. And Kate was pretty sure that she was also trying to figure out if Brad's tool was attached to the kind of male that she could have a good time with, maybe even go "on safari" with for a couple of days of non-stop exclusive mating, the kind of male who would be sweet and fun and wouldn't beat her or go all dominant on her. Kate would have to find a way to prove her theory, and maybe demonstrate it experimentally. But she knew she was right. It was already a great result, definitely publishable in a big journal. She turned around and saw Chad with the camera again getting it all on video and she gave him a big thumbs up. He nodded and smiled at her, pleased with himself. On the way back down the mountain they stopped at the same swimming hole as yesterday but this time they all stripped down right away and dove in. Everyone was too hot and tired to eat. They swam around and treaded water for a while. Kate could feel Chad's eyes on her when she floated on her back in front of him and then she watched him for a while when he returned the favor and floated on his back in front of her. Ellen and Courtney started splashing each other and trying to dunk each other under water and after a few minutes Chad joined in, and Kate even splashed them once or twice, laughing. Then they all lay out on their towels on the grassy slope. All three girls were wearing bikinis and Chad had on his customary speedo. Kate turned on her side to face him, both of them still dripping wet. She was wearing the blue bikini again and it showed off her breasts and hips nicely. "So do you always swim during the off-season? Is that how you keep in such good shape?" Chad turned on his side and faced her, his hand playing with the wet grass between them, plucking out blades slowly and tossing them aside. He looked up at her. "No, I used to swim in high school but I haven't much since. But my soccer coach made me promise to swim every morning if I came on this trip so I'd be ready for double sessions when I got back. I'm trying to keep at it. But my shoulders are getting pretty sore to be honest, and my hips too." Kate nodded seriously. "I noticed your hips looked tight when you were climbing up the mountain yesterday. Yoga would really help with that. Have you ever tried it?" "No. To be honest the trainers think all that yoga stuff is kind of soft. No offense." "None taken," Kate laughed. "Maybe it is soft, but it will definitely make you more flexible. You should let me show you a few poses after you're done with your laps tomorrow. I used to teach classes back in grad school." "Sounds great. Thanks." "It's a date!" chirped Courtney. She and Ellen busted out laughing. "Pipe down you too," Kate chided them, not serious though, "and try to keep your brains out of the gutter." "I would if I could," Ellen shot back. "It must be something about the air in this place but ever since we got here everyone has turned into total fuck fiends. It's crazy over in those bunkhouses let me tell you." She elbowed Courtney in the ribs and they both cracked up again. "That reminds me," said Courtney, "we've almost run out of condoms already. I had everyone in the group pool theirs yesterday and we only have six or seven left. I guess no one expected to be having this much sex. Do you think you could ask Roger or Alex to get some the next time they go to the village?" "I can try," said Kate, "but you might be out of luck. Condoms are pretty scarce around here with all the foreign aid cut backs." "Well, if they could try that would be great. Just about all the girls are on the pill so it's not like they'll all end up pregnant or anything, but it'd be great to have the condoms too." Kate nodded and turned on her side to face Chad again while Courtney and Ellen started chatting and flirting. Chad was on his back now with his forearm over his eyes and his scent pouring off his armpit and making Kate feel woozy. She took a deep breath and closed her eyes and before she knew it she was asleep. It had been another hard night and she was exhausted. She had taken a sleeping pill at 2am out of sheer desperation and the effects of it hadn't worn off yet. Advanced Primatology Ch. 06 When she woke up she was on her stomach with her nose so close to Chad she could smell his neck and even his breath. Their shoulders were touching. He was on his back with his head turned toward her slightly. Kate breathed in deeply and looked down and noticed that her right hand was on Chad's stomach as it rose and fell with his breath. Then she felt the back of his hand resting lightly on the top of her thigh. His fingers were positioned so that if he moved them just slightly, or if she squirmed her butt just a little like she was doing right now without quite realizing it, they had a pretty good chance of brushing up against her ass or her crotch. Kate breathed in his scent again and moved her fingertips just a little on his tight abs, almost massaging them. He stirred a little in his sleep and his right hand turned over so his fingertips were resting against the bottom of her cheek. It felt nice. It would have been the simplest thing in the world to just nuzzle up into his neck and maybe start kissing it a little, and to reach down her hand toward the speedo and play with the dark hairs trailing down from his belly button. But that would be cutting it a little close with her new rules, she thought to herself, the one about not making out with him, and maybe even the one about not jerking him off. She wondered if Courtney and Ellen were still lying next to her on the other side but she was too tired to roll over and look. Her head felt like it weighed a thousand pounds. She brought her face a little closer to Chad's neck and moved her hand a little lower on his stomach and in a few minutes she was asleep again. When she woke up all three of them were gone. She wasn't sure for a minute whether she was awake or having an intensely vivid dream. She heard voices, or groans maybe, behind a dense wall of foliage on the other side of the pool. Without even thinking about it she stood up and walked over toward the sounds and parted the wet leaves and stepped into a cool shady nook, just big enough to fit her. Through the wall of leaves on the other side she could see into a little sunny clearing where she could make out Chad and Courtney and Ellen. Chad was laying on his back in the grass and Ellen was kneeling between his legs with his cock in her hand, stroking it long and slow while the two of them held their mouths open wide and played with each other's tongues. Their eyes were open wide too and they were looking straight at each other. Courtney was on her knees behind Ellen with her left hand inside her and her big right hand on her tits. She started fondling them hard, pinching the nipples when they came loose from Ellen's tiny bikini top. Ellen wriggled her hips and laughed and gasped a little louder. "You like the way that feels darling?" Chad drawled, pulling away from her a little and nodding down at his hard cock in her pale hand. Ellen nodded and started to stroke him a little harder. Courtney smiled up at Chad and brought her nose to Ellen's backside. She stuck her tongue out and licked Ellen long and slow from her clitoris to her anus and started tonguing it in slow circles. "Oooooooohhhhh," Ellen gasped, and when she did Chad got up on his knees in front of her and put his hands in her red wavy hair. Kate was in very dark shadow and she had a dense wall of leaves between her and the kids who were in bright sunlight. She was an experienced observer of primate sex and she knew that in these conditions there was no way they could see her if she didn't move too much. She was absolutely transfixed and she kept wondering if this was real or if it was a dream. She was on her haunches staring at them wide eyed and she was sopping wet already. That sleeping pill had really messed her up. She was practically drooling. She shoved her hand in her bikini bottom and slid two fingers inside her and started probing for her g-spot, slowly at first but then faster once she found it. She had to hurry. She felt like she had lost her mind. It was the hottest thing she had ever seen. The whole scene with the three of them was like a vision, but in particular Chad's hip bones and his soft black curls and his big round balls. And especially his beautiful cock in Ellen's pale hand. It was longer than Brian's and thicker, no doubt about it. But it was more than that. It was just so beautiful somehow, she thought, and so did Ellen clearly. Ellen was circling her tongue around the broad purple head while her small hand stroked the whole length of him. The blue veins on the side of his shaft glistened with her saliva. Kate had a crazy idea to go back for her binoculars or even the video camera but she was too turned on to move. She had her other hand in her bikini top now. She was flushed and hot. Courtney was tonguing Ellen harder and she was bucking her hips and holding her mouth open wide while Chad held the back of her head and fed his cock to her slowly, careful not to choke her or be too rough. He was thrusting his hips a little and groaning out his pleasure while her saliva dripped off him in thick streams. It was just so thick and hard and beautiful to look at. Kate wanted it to be her down there. She wanted it to be her with Chad's cock in her mouth and his big balls in her hand while he groaned and bucked his hips for her, and she wanted it to be her pussy that Courtney was licking and her ass that was shaking with pleasure. Chad was lying back on his elbows again now and he was groaning harder as Ellen wrapped her lips around him tightly and sucked him faster and faster, as much of him as she could take. Kate saw the base of his shaft start pulsing as Ellen's eyes went wider. Chad thrust his hips up toward her and held her to him, his big balls contracting upward as the base of his cock kept throbbing and throbbing and Ellen started to gag. She pulled off him and spit out a long stream cum while her hand kept stroking him and he kept cumming and cumming more of it in long thick ropes. His stomach and chest were covered with pearly drops now and they were glistening in the sunlight as his stomach heaved. Kate had cum hard and fast at the same time as Chad, like a big wave had crashed right on top of her, and now she was sitting there on her haunches trying to catch her breath and get her bearings again. Chad had Ellen in his lap facing him now and he was kissing her neck while she held him tight and panted hard. She was rubbing her tits against him and they were covered with cum. Kate backed slowly out of her dark nook and walked past the swimming hole and lay back down on the grassy slope. Maybe ten minutes later she felt Chad's foot kicking her lightly in the ribs. "Wake up sleepyhead, we've got to get going or we'll get caught by this storm." She opened her eyes and gazed up at him in the speedo. She smiled at him and nodded. Part 4 Elise zipped up her rain jacket and pulled up the hood and ran out into the torrential rain. The sky had opened up almost as soon as they'd gotten back to the lodge and there was lightening and thunder over the lake now. They'd been cooped in the girls' bunkhouse for hours. She ran the 50 feet over to the boys' bunkhouse and ducked inside and closed the door behind her. The other guy (Kyle) was sleeping with his headphones in his ears on one side of the room and Kevin was reading a book on the other side and he didn't have a shirt on. Elise had noticed his skinny body and his ripped abs at the lake the other day and she'd kind of liked them. He was nowhere near as hot as Chad but he had a devil-may-care charm like a lot of cute guys in bands, and, more importantly at the moment, he had a real gift for scoring amazing weed. He was one of those guys who you could drop out of a plane anywhere on the planet and in an hour or two they'd be getting high on the finest herb available. He'd scored some from the boat pilot on the trip over the lake and now he had a steady supply. He had a joint in his hand now and the smell of it was making Elise horny already. She didn't smoke much normally but that first night in Dar es Salaam when she'd gotten high and ended up fucking Chad all night had been kind of a revelation. She'd cum so many times she'd lost count and each orgasm seemed harder and bigger than the one before. She was looking forward to what was about to happen. Ellen and Courtney had told her that Kevin had a pretty good dick and that he knew how to use it, although he wasn't in Chad's league. But then again who was? Not even Professor Phare, if she was honest with herself, and a couple of weeks ago he was by far the best fuck she'd ever had, and the biggest cock she'd ever seen in person. But now he seemed liked kind of the warm up act for Chad, who she hadn't gotten nearly enough of before he switched to Jess, and who she wanted back in her bed very badly, whatever she had to do. She walked over to Kevin and sat down on the bed next to him. She could see the wheels turning in his head and his heart beating faster. "Can I have a drag?" she asked, looking down at his hand and maybe a little at his crotch too. He handed it to her and she inhaled deeply and held it in. She leaned forward and exhaled slowly right in his face. "I tell you what, stud, how about you bring some of that good weed over to the girls' bunkhouse in ten minutes and we have a little party over there? Everyone is so bored and restless but I'm sure we'll find something to do. Sound good?" "Sounds good, yeah, I'll be right over." Bet your ass you will, thought Elise, as she stood up and sauntered out of the room. The idea had come to her the night before when she'd been laying in her bed bored and frustrated because she wasn't getting any more of Chad's hard body and his sweet cock. She remembered that she had some trashy BDSM novel on her phone and that it always got her hot. She reached for her phone and started reading it and before long she was really getting into it. It was about a female alien who comes to earth and disguises herself as a biologist in a university lab somewhere and one by one she ties up all the male scientists in the lab, and all the male students, and fucks them in a special room behind her office. She drains their balls empty straight up into her womb, which is actually some sort of storage receptacle for holding earthling seed. Her mission was to take it back to her home planet and repopulate her race. But then she got hooked on some hot, teenaged earthling cock and the tension started to ramp up. That was the part that Elise really liked and before she knew it her hand was in her panties. Ellen noticed what was happening and came over and lay down next to her on the bed. "What are you reading? I want some of that." Elise started to read it out loud and before long Ellen had her hand inside her panties too. Elise laughed. Ellen was in one of those "feminist" phases where she considered it her mission in life to explore her newfound capacity for multiple orgasms, whenever and wherever she could. And they'd all shared one of Kevin's joints a little while ago so they were all feeling relaxed and horny as well as bored and cooped up. It was too buggy to be outside and it was too early to go to sleep. All the girls were ready for bed and they were all practically naked. Before long a bunch of the girls were sitting next to Elise's bed and listening to the story while they laughed and poked and teased each other about how hot it was making them. Sanjana had her hand inside her boy shorts and her nipples were sticking out through her tight white tank top. She was a curvy South Asian girl with dark almond shaped eyes and the biggest tits in the group by far. Elise had seen Chad looking at her and she bet he was picturing his cock in between those beautiful breasts. Boys were so predictable. And Pamela—the skinny Korean girl who ran marathons and was a total nerd but also had a kind of sexy vibe underneath it all—was sitting with her legs spread and her panties pulled to the side while Courtney eyed her hungrily. In a flash she was on her knees in front of Pamela and they were making out and groping each other. Elise had seen Chad eyeing Pamela's skinny ass too and she couldn't blame him. Ten minutes later and they were all gasping for breath and pulling their panties back up and their tops back down while they laughed and poked each other and asked each other what the fuck had just happened. They were feeling relaxed and comfortable with each other and that's when Elise got her little idea. She'd noticed that there was some climbing gear in one of the equipment bags the other morning and she'd always been pretty handy with the ropes, and carabiners and clamps and such. Being an experienced climber was just one of her many preppy talents. And clearly it wasn't just her that found this whole femdom thing kind of a turn on. What if she brought Kevin over tomorrow night with one of his big fat joints and they smoked it together and then tied him up and had a little fun with him? Elise was happy to take the lead and the other girls could join in if they wanted or just watch. Sanjana and Pamela were into it right away, but Courtney and Ellen weren't sure for some reason. But they agreed to clear out of the bunkhouse so the other girls could have their fun. Maybe they'd join in next time if it all went well. Elise and Sanjana and Pamela had arranged a bunch of blankets and pillows in the center of the room and they were all sitting there in their panties and tank tops when Kevin walked through the door and pulled his poncho over his head. His t-shirt rode up when he raised his arms and his abs looked really good and his hips did too. Elise patted the blanket beside her and he walked right over and sat down next to her and pulled out a big fat joint. He held it up to her mouth while he lit it and she breathed in deeply. Then she grabbed the back of his head and put her mouth over his and blew out long and slow. It was corny, she had to admit, but it was pretty hot too. The other girls seemed to enjoy it. They were kind of sticking their tits out a little as their eyes went wider. Elise motioned for them to scoot closer as she started making out with Kevin and pulling his shirt over his head while she handed the joint to Pamela. Pretty soon they were all making out with him and passing the joint between them and after a couple of minutes Elise gave the signal. Sanjana scooted over behind Kevin and started raking his chest with her nails while she kissed his neck. And Pamela scooted down to his feet and held one of them between her legs while she massaged it and rubbed his toe against her crotch. Elise looked over her shoulder and she could see a big wet spot on Pamela's panties. She smiled and pushed Kevin's chest with both hands until he was supine on the blankets and then she reached down and stroked his cock a little through his shorts. It was nice and hard. It would definitely do the trick. She gave another signal to the other girls and they both reached for the ropes on the floor and slipped them around Kevin's wrists and ankles while Elise pulled his waistband over his cock and let it spring free. She wrapped her hand around it tight and purred for him while the other girls pulled the ropes hard and fast. Before he knew what was happening Kevin's arms and legs were yanked hard and he was spread eagle on the floor with his eyes wide open and his heart pounding against his chest. Elise straddled him in her lacy black panties and peeled off her tight white tank top to reveal her lacy black bra. She knew how sexy it looked. Professor Phare had bought it for her as a little present after the fourth or fifth time they'd fucked in his office and she wore it to the hotel room the first time they met there. It always made him rock hard and he always came gallons all over her when she wore it. She loved it. She'd packed it at the last second when one of her friends had called to tell her that Chad Berwick would be going to Tanzania too. She'd seen him around the anthropology department and she definitely wanted to get a piece of that. She dug her nails into Kevin's chest and lowered her wet folds onto his shaft and started sliding up and down the length of him. She could see the wheels turning in his head frantically and she could sense his excitement. "How about we play a little game, okay stud?" He nodded. "Good boy." She nodded to Pamela who pulled out the little blindfold Elise had kept from the international flight and slipped it over Kevin's eyes. Pamela lay down next to him and turned his head toward her and started kissing him wildly, her tongue in his mouth. Sanjana lay on the other side of him and started licking his armpit while she cupped and caressed his balls. Kevin was groaning already. "Careful, stud, you don't want to blow your chance. Just try to relax and make it last." Elise's lips were opening a little for him as she kept sliding them along his shaft. It was rubbing her clit in just the right way and she was really getting into it. "Here are the rules, okay stud. You're going to lie still right there like a good boy and then one of us is going to do something nice to you and you have to guess which one of us it is, and if you guess right we'll do something even nicer. Sound fun?" Kevin nodded and groaned. "Let's start with an easy one." She pulled her tits out of the bra and lowered them down to his mouth and let him suck on them a little, one after the other while she circled her wet pussy around the tip of his cock. "Well, what's your guess, stud?" "Elise," he gasped. "Good boy," she teased him. She rocked her hips back and let the tip of his cock slip inside her just a little while he groaned and tensed his stomach muscles and tried to thrust up inside her deeper. Elise rose off him and pinched his nipples hard. "I told you to lie still and be a good boy. Are you going to play by the rules or do I have to get rough with you?" Sanjana and Pamela started laughing and scratching his ribs and biting his neck as they rubbed up against him. Elise nodded at Pamela. She got on her knees and scooted over to straddle Kevin's face with her skinny legs. She pulled her panties to the side and lowered her wet pussy onto his mouth and started to circle her hips slowly while he grunted and puckered his lips and kissed and sucked her hard. "Jesus, oooooohhh fuck," gasped Pamela. It was a dead give away, if her skinny thighs hadn't been already. Kevin twisted his mouth to the side to get some air. "Pamela!" he called out. "Good boy again," teased Elise as she lowered her wet pussy to his shaft again. She grabbed the base of it firmly and angled the tip to her wet hole. Then she rocked back slowly and took him inside her in one stroke. She held him there while she reached back and raked his balls with her nails. He was groaning hard but the sound was muffled by Pamela's crotch on his mouth again. Elise pulled off him quickly, afraid that she'd pushed him too far and he'd go over the edge and cum inside her, which she fully intended for him to do, but not yet, not by a long shot. She was enjoying herself thoroughly but she was also doing this so that the story would get back to Chad, and she wanted to be a really good story, one that would drive him crazy and lead him straight back to her bed and her pussy for the rest of the trip. Her pussy belonged to him now and his cock belonged to her, till death do them part, even if he didn't know it yet. Elise switched places with Sanjana who was sliding HER wet pussy against Kevin's shaft now while Pamela rode his mouth. Elise grabbed his foot and held his big toe in her fingers and slid it inside her. Sanjana tapped Pamela on the shoulder and motioned for her to get off his face and when she did Sanjana leaned forward and just smothered him with her big soft tits. Then she pulled back a little so he could lick and suck and bite them. Advanced Primatology Ch. 06 "Sanjana," he groaned. "That one was too easy," she teased him as she squirmed her chest away from him. "But you still get your reward." She reached back and held his cock in place while she impaled herself on it slowly, gasping as it entered her and she settled her ass down all the way to his balls. He was pretty well endowed, Elise reflected, and this might be one of the bigger ones Sanjana had been fucked by. And she was really fucking it good now! She was slamming down on his cock so hard that his balls were shaking and her ass was shaking too. It looked beautiful. Elise held Kevin's heel to her crotch and rubbed her juices all over it. It went on like this for ten minutes or so. Sanjana fucking Kevin with her big ass while Pamela rode his face with her skinny one. Then the girls would switch places. He had some impressive stamina. Pot could do that for guys, if it didn't make them soft, which definitely wasn't the case with Kevin. Elise was watching Pamela ride him smooth and slow with her skinny ass when she saw that tell tale sign at the base of his cock as the big vein up the side of his shaft started to expand and pulse. She tapped Pamela on the shoulder and she moved aside so Elise could finish him off like they'd agreed. She pulled her tits out of the black lacy bra again and lowered them to his mouth while she pounded his shaft and he grunted and groaned. Then she rose up off him and held her crotch a foot or two above him while he thrust his hips up as high as he could in the restraints and searched for her with the tip of his cock. "What the matter, sweetie, you can't reach far enough? You can't find my pussy? Should I untie you now so you can fuck me however you want to? Should I let you fuck me hard now so you can finish inside me and those big balls will feel all better?" Kevin was nodding and grunting and thrusting his hips, almost desperate to get inside her again, almost whimpering. Elise laughed with delight then lowered herself back down on him again and reached forward to pull the blindfold off. Sanjana and Pamela were sitting on either side of him with their legs spread wide and their fingers inside them. Everyone was moaning and bucking their hips and gasping for air. Elise was giving him the best ride he'd ever had in his life by far and the fact that he just had to lay there and take it from her made it that much hotter. He was about to blow and so were all three girls. "Hmmm now," teased Elise, as she caressed his balls and rode him a little slower. "Should I keep all this cum for myself or should I let the other girls get a taste too? What do you think stud? Do you want to cum inside me or would you rather cum on all three of our faces?" Kevin tried to answer but Elise smothered his mouth with her tits. "What's that sweetie? Well, it doesn't matter. I've already made up my mind." She pulled her tits from his mouth and leaned back until her hands were on his shins. Then she rose off him a little so he could meet her downward thrusts with his upward ones. They were fucking like maniacs now and Elise was about to cum hard around his shaft, as much from the idea of what she was doing to him as from the sheer physical pleasure he was giving her. And Sanjana was quaking all over and her big tits were jiggling, and Pamela had her whole hand inside her and when she pulled it out she looked like she was squirting which Elise had never seen before and which brought her right over the edge. Kevin's cock pulsed against the walls of her pussy and a jet of sperm shot right up inside her, hot and quick. It felt delicious. Kevin was grunting and groaning and thrusting his hips and it didn't seem like he would ever stop cumming and it didn't seem like Elise or Sanjana or Pamela would either. The next thing Elise knew she was collapsed in a heap on Kevin's chest while she scratched and massaged it and purred in his ear. He was making out with Pamela and Sanjana was kneeling between his legs and playing with his cock and he was already getting hard again. Part 5 Kate was trying to concentrate on the video of Brad and Mahalia on the laptop but she kept getting distracted by all the flirting and sexual tension in the room. She was dripping sweat from all the humidity and they'd been cooped up all day in the common room while the rain poured down in sheets and huge bolts of lightening lit up the lake. She was trying to figure out why Mahalia was quite so fascinated by Brad's "teenaged" cock, and if that meant she was going to go off alone with him when she came into heat and let him mate with her exclusively the whole time she was fertile. And she was wondering if that was maybe a different story to tell about how chimps chose their mates and how genes were passed down than the one all the male scientists tended to focus on, the one about the hot, young "pink lady" who'd been mounted by all the more aggressive males today, but the most times by the most aggressive one who had started guarding her and trying to keep her close. She was trying to watch the video carefully but she kept getting distracted and she was starting to feel really pissed off at the other women and Chad. None of the women were wearing much of anything at all. They were all comfortable by now sitting around with Chad in whatever they'd be sleeping in or whatever was comfortable to put on after dinner when they settled down to the tedious evening work of going over their notes and logs and maps and reviewing the videos from the day. Kate didn't have a bra on and she was wearing a loose grey tank top with spaghetti straps and a pair of navy blue boy shorts with nothing underneath. And Jess and Karin and Ellen and Courtney were wearing pretty much the same kind of thing. Elise had begged off work this afternoon with an upset stomach. Chad was wearing a tank top and some long soccer shorts. He was sitting on the couch between Jess's legs while she massaged his shoulders with one hand and read her field notes with the other. He kept rolling his neck to try to work out a kink in it while he tried to work out some problem with the camera at the same time. Ellen was in Courtney's lap on the floor by the wall with some big pillows propped up behind them, and Karin was across the room in a big plush chair with her legs stretched out and her laptop in front of her. She wasn't wearing a bra either and her white tank top was clinging to her sweaty breasts and they looked larger than normal and maybe firmer somehow. Kate had her laptop on the coffee table near the center of the room and she could see all of them from where she was sitting. A couple times she caught Chad starting at Karin's chest (not that she could blame him) and she was pretty sure Karin had caught him too. But she didn't seem to mind one bit, which surprised Kate. It was really quite a luxurious room. Brian had convinced UNC to come up with some big funds for the trip and the lodge was a rather expensive one, and quite stylish in its own rugged way, at least the women's cottage. Karin looked up from her laptop and asked Ellen and Courtney a question. "So Elise wasn't feeling well today, huh? That's strange. She seemed fine hiking down the mountain. I could really use her here to help me make out her handwriting in these field notes." "Um, well, not to be a tattle tale," replied Ellen laughing as Courtney pinched her side, "but I think she wasn't feeling well in the sense that she needed a hot cock injection this afternoon or she was going to lose her mind." Karin sat forward in her chair and opened her eyes wide. Kate noticed Chad's ears prick up too. "Really, whose cock? You have to tell me." "Kevin's," Ellen laughed. "She and Sanjana and Pamela were planning a little party for him this afternoon and I bet she's feeling just fine about now." "O my god! What kind of party," Jess gasped. "You can't hold out on us now." "O I don't know," said Courtney, "something to do with all that climbing gear in the big duffle bag, you know, all those ropes and clamps and such." Jess and Karin busted out laughing but Chad practically leapt out of his chair with an anxious, almost pained look on his face. He looked like he was about to run right over there and put a stop to whatever was happening in the girls' bunkhouse without him. "O no you don't tiger," teased Jess. "You're not going anywhere right now." She grabbed his shorts by the waistband and pulled him back down on the sofa with her. "Actually, Jess, could I borrow him for a few minutes," whined Karin, in a voice Kate had never heard before. "My shoulders are killing me from carrying that big pack with the rain gear today and I could use a big pair of hands to work out the kinks." Ellen and Courtney poked each other and laughed but Jess shrugged her shoulders and walked over to take Karin's seat while Karin stood up and walked over to the sofa and laid down on her stomach. Chad smiled and sat beside her in her tiny maroon boy shorts and started to work her arms and shoulders and neck confidently. He really knew what he was doing and before long Karin was moaning and telling him how nice it felt, and before long Chad had moved on top of her and he was straddling her ass while he worked her back a little lower and Karin gave out little sexy moans. Kate could tell that it was making Jess a little jealous and to tell the truth it was making her jealous too. Karin was such a beauty and she was in her absolute prime. She was the kind of woman who could make Chad forget about every other female on the trip, including her, if she had a mind to. Jess was crossing and uncrossing her legs and biting her lip and after a while she started to tease Chad and distract him. "So I wonder what they're doing with Kevin over there? Do you think they really tied him up? Do you think they're all taking turns having sex with him over there?" "I hope not," said Ellen, "We only have about six or seven condoms left between all of us and I want a few of them for myself." "Maybe they're not using any," teased Jess. "Maybe they're all riding him bareback, one at a time. Lucky boy. Sanjana is such a hottie with those big boobs and hips, and Pamela looks all nerdy on the outside but I bet she's filthy when she gets that skinny ass moving." "You don't know the half of it," laughed Courtney. "It's been insane over in that bunkhouse since we got here." Chad's face was bright red and he'd almost completely stopped massaging Karin by this point. She was hunching her shoulders, and sighing loud, and getting more and more annoyed. "Do you ladies mind," she snapped, only half playing. "You're distracting my masseuse here with all this sex talk and I was just starting to enjoy myself." "Yeah, well don't get used to it," Jess snapped back, only half playing too. "That masseuse belongs to me. I've only loaned him to you because your fiancé isn't here and I took pity on you. But I'll definitely be claiming him back in a couple hours." Ellen and Courtney busted out laughing again, and then Courtney grabbed Ellen tight and kissed her neck a little. "Actually, that reminds me," Jess continued, lowering her voice. "I know this might be a crazy question, and feel free to say no, but is there any chance I could borrow your diaphragm tonight and try it out? It's not a great time for me and it sounds like rubbers are pretty scarce around here." Ellen and Courtney were sitting straight up now, wide eyed with disbelief at how much Jess was saying in front of them. Kate felt her irritation rise. She wasn't paying any attention at all to the video now. Karin pushed herself up with her strong arms and practically threw Chad off her. "Why the fuck would I bring my diaphragm on a trip when my fiancé is on the other side of the planet, and why the fuck would I loan it to you if I had? Are you fucking crazy asking me that?" You could have cut the air with a knife. Kate took charge. "Chad, take a walk big boy. The females have some things to discuss." Chad did as he was told. As soon as he was gone Kate stood up and tore into the other women. "Look, can we be a little bit more like bonobos here and a little less like fucking patriarchal troglodytes?" "What are you talking about?" asked Karin. She was still really pissed off. "I mean let's use sex and flirting and all that good stuff to have less tension in the group, not more." "Who's flirting?" snapped Karin. Kate could tell she was feeling defensive and the slightest thing would set her off. "Not you, Karin. I know you didn't mean anything by it other than a massage. I'm talking more to the younger ladies here. That wasn't nice the way you were teasing Chad about Kevin while Karin was trying to use him to relax. Don't you know not to get between a high status bonobo and the guy that's grooming her? I thought we were all primatologists here." Everyone laughed, including Karin. "And don't even try to tell me that Elise's little party today wasn't meant to make Chad crazy with jealousy. Look Jess," Kate continued, "I know I said you could have sex with Chad every night but maybe you're going to have to share him. It seems like he's the hottest male in the group and we could all use some of that, I mean, it seems like all of you could. Not you, Karin. Sorry." "What do you mean share him?" asked Jess, almost pouting. "I don't know! Think like a bonobo sweetie! Make a schedule or something with the other girls. Just make sure to leave time for a nice long massage for Karin every once in a while." They all laughed again. The tension had lifted by now and when Kate looked outside she noticed that the sky was clearing a little and the rain had stopped, though it looked like it would start again soon. "I don't know, Kate," Jess laughed. "You don't know what that boy can do to a girl, but Ellen and Courtney sure do. I'm kind of used to it by now, to tell the truth, and I don't know if can go a day or two without it. Maybe I'll have to start throwing some 'Chad parties' over here so the other girls can get a little of that fat cock too and I won't have to miss out." Courtney and Ellen were practically wetting themselves they were laughing so hard and Karin had her legs crossed and was biting her lip. "Whatever you need to do Jess," Kate rolled her eyes and laughed. "I'm sure you'll be very discrete." She turned to Karin. "Take a walk with me before the rain starts again." Karin stood up and they walked slowly down to the lake and then sat down under a little thatched cabana by the shore. Kate turned toward her and looked at her seriously. "What was going on back there, Karin? Why'd you lose it with Jess like that? And, no offense, but what was all that flirting with Chad about?" Karin started talking and pretty soon it was all flooding out. She told Kate that she didn't know Chad was going to be on the trip and she wished he wasn't because it was creating real problems for her. It turned out that a few months before the trip, while they were stressed out with planning the wedding and everything, Karin's fiancé Rick had sat her down and had a serious talk with her. He was a psychologist and he had a piece of advice for her that was going to sound crazy at first but she should think about it seriously and she should talk with him about it openly. He'd had so many female clients who get married too young, before they'd sown their wild oats, sexually speaking, and so many of them ended up obsessed with the idea of cheating with another man, and most of them ended up doing it in the end and feeling awful about themselves and maybe even ruining their marriages. He just loved Karin so much and he knew she'd only been with a couple of guys before him, and that was in high school so it barely counted, and he didn't want her to end up going through what so many of his female clients did. He loved her too much. He thought she should think about having a fling or two, discretely, before they tied the knot and committed to each other exclusively for the rest of their lives. He didn't want to have a fling himself because he was much more experienced than her sexually and she was the only woman for him. But he would understand if she wanted to. Karin was horrified at first and hurt and angry, but then she saw it as part of what she loved so much about her future husband: his understanding and sensitivity and his refusal to be constrained by conventional morals and ideas about how to be a real man. They got a little buzzed one night and ended up making a bucket list of guys she had permission to sleep with before the wedding this summer. It was mostly celebrities and sports stars (Roger Federer was near the top of the list) but there was one "real" guy on it, a hot soccer player from Karin's lab section. Chad Berwick. Her fiancé had loved it when she described Chad to him—his lean body and long dark bangs that swept down over his deep blue eyes. And he'd loved it even more when she played along with him and pretended that she'd been fantasizing about him for weeks, and that she could barely keep her hands off him during those long boring lab sessions, or when he visited her office hours and the two of them were alone in the little grad student office that used to be a broom closet. They had phenomenal sex that night and Rick ended up cumming inside her so hard that she came too. She'd never done that before from penetration alone. It was so hot because they'd gotten so excited and worked up that she'd forgotten about birth control entirely. She'd just gone off the pill and was using her diaphragm again, which felt much better than a condom but which she wasn't completely crazy about truth be told. The pill fucked you up, sure, but there was nothing better than raw sex with a hard naked cock and a stiff shot of cum straight up inside you. She'd been having vivid fantasies about Chad fucking her bareback ever since then, practically every night. She was horrified when she realized he was on the trip and that they'd be working and living closely with each other for a whole month. In a way she kind of had "official" permission to fuck him, though her fiancé had no idea he was here, and in a way Karin really wanted to. "So do I," said Kate, "and I've been fantasizing about him too, ever since I heard him back at the hotel." Karin gaped at her. "Don't worry about Brian," she added, reading Karin's thoughts. "He's been screwing Elise for god knows how long now." "I know," said Karin, her face white. It was Kate's turn to gape now. "I'm sorry, Kate. I caught them in his office one day and I wanted to tell you, but Brian said that it would just hurt you for no reason and that if I did tell he had ways of making things difficult for me." Kate shook her head. She wasn't mad at Karin at all, poor thing. That bastard! That patriarchal shit! "Listen Karin, I think you should do it. I think your fiancé is right. I think he's left the door open for you and you should just walk right through it. And I think you'll be stronger for it and your marriage will be stronger too." Karin nodded her head. "Maybe. I don't know. What about you? Are you going to do it?" Kate shook her head. "No, sweetie, that door has closed for me. I'm on the tenure track and I could get in serious trouble for having sex with a student. And I'm already married. And unlike Brian that actually means something to me." The rain was starting up again and the two women stood up and walked slowly back to the cottage. Courtney had gone back to the bunkhouse and Chad, Ellen and Jess were sitting cross-legged on the floor and passing around a big fat joint. It smelled fantastic. They offered it to Kate and Karin but both women excused themselves and went to their tiny bedrooms. It wasn't late but it had been a long day and both of them were tired. Advanced Primatology Ch. 07 Part 1 Kate liked doing yoga with Chad like this. She liked it even more than she liked watching him swim laps in front of her while the sun rose over the lake like she'd been doing ten minutes ago, admiring his powerful shoulders and long lean arms as they pulled him across the calm surface. She'd been going through her sun salutations like always, breathing in and out and feeling that warm glow start building in the little spot between her stomach and her groin, and then spreading out from there until her whole body felt alive and open. She was facing him in warrior pose as he walked toward her up the green slope and grabbed his towel from the ground and started to dry himself. She felt her stomach drop and her lips moisten. He flashed her that wide sweet smile. Now she was guiding him through some simple poses to help open his hips and back and shoulders. He was so strong, but he was surprisingly tight for such a young guy. Like lots of soccer players. Like her husband, in fact. She pushed him right out of her thoughts. Chad was on all fours facing the sun and she was on her knees beside him while she tried to talk him through cat pose. It was a little awkward to be in that position with him, but she was his professor and he was her student and she was trying to teach him something so it was all perfectly fine. The pose was the most basic one she could think of, and the most gentle on his back and shoulders, but he just couldn't get it. It was simple once it clicked for you but a little tricky at first because you had to get the breathing right, and the rhythm. Lowering your back and relaxing it as you breathed in and let your chest expand and your shoulders and head rise, then breathing out and hunching your shoulders and letting your lower back arch and your backside relax. It was subtle, but powerful once you understood how it worked. Chad was still a little damp from his swim in his long loose trunks and his wet bangs were hanging down over his blue eyes. Water was dripping onto his nose and his jaw. Jesus he was handsome. You could draw a line down the center of his face and flip the halves of it and he would look exactly the same, except for the bangs. His jaw was so square, and sharp and symmetrical. His skin was dark and his blue eyes were set deep and shadowed a little by his brow. She wasn't sure if she liked the new beard he'd grown since the trip started. She wasn't sure if she liked him better with his smooth and boyish look or with this rougher one, more mature. Maybe she should ask him to shave it for her. That would be kind of hot. Or maybe she should just run her fingers through it and tell him how handsome and distinguished and grown up it made him look. They were so comfortable with each other now that they'd been working closely together for a few days, and she was really enjoying the way it gave her license to flirt with him a little more, to play the part of his encouraging teacher. She could compliment him on being in such good shape, or call him little pet names, or maybe run her fingers through his stubble. Would that cross a line? She definitely wanted to feel that beard against her fingers and hands, and maybe against her neck and shoulders, and maybe even against her stomach and the inside of her thighs if she was honest about it. She was probably going to have to rethink her new rules about what she could and couldn't do with him. He looked so thin and graceful when she watched him walking up toward her from the lake after his swim, but now that she was right up next to him she realized how strong he was, how massive and powerful in his shoulders, and in his hips, and his whole core. He was having real trouble with the pose so after a minute or two she put one hand on his chest and one hand on the small of his back to guide him through it. She pushed his lower back down gently as she told him to breathe in slowly. Then she shifted her hands and pushed his stomach up just slightly with her fingertips while she told him to let go and exhale. Kate couldn't stop thinking about last night in the cottage when she'd watched him take Jess first and then Ellen on the floor in the living room while she hid behind the sliding door to her tiny bedroom. She was thinking about that moment when Ellen was lying underneath him while he did a half pushup over her so that his hard body was suspended just a few inches above her. She was thinking about how Ellen grabbed him and pulled herself up on him, like a little monkey almost, and started biting his neck and rubbing her sweaty tits all over him, and her wet crotch too. Kate's knees had buckled it had looked so lewd and hot. She had really wanted it to be her down there clinging to him tightly and rubbing her sweaty breasts and stomach all over his hard body while he held her up off the floor with his powerful arms. And she wanted it to be her when he rolled Ellen into a little ball and fingered her wet slit, almost teasingly, and when he held her by the ankles and raised her legs up until she rolled back on her shoulders and looked up at him. And she wanted it to be her as the tip of his beautiful cock, so blue and plump in the moonlight, pushed into Ellen's swollen lips and parted them. The sight of it had made Kate feel so wet and hot and she'd started bucking her hips and her tiny shorts were around her knees and she had two fingers inside her. There was a cold breeze blowing in off the lake and her tank top was pulled up over her breasts and her nipples were rock hard and jutting straight out at Chad, almost calling to him. She was watching his ass clench and unclench and his hips slide forward smooth but hard. Kate hadn't expected it: the strength and the skill and the raw desire. It took her breath away. She'd grunted loud, just once, before she caught herself. She remembered it all like it was a dream. She was kneading her breasts with one hand and her shorts were around her ankles as she rocked her hips and slid three fingers inside her, and out again, and right back in, hard and smooth just like Chad's cock was doing to Ellen. Chad had Ellen's ass in his hands and she had her legs wrapped around his thin waist. She he was rolled back on her shoulders and watching him through half-lidded eyes and making little sexy moans and gasps so he'd fuck her harder and deeper. She could tell that Ellen was right on the edge and she could tell she was too. She was admiring Chad's butt muscles and his heavy balls from behind while she pouted at him like Ellen and wished he could turn around and see her. She was gasping and sticking her ass out behind her a little so she could get her hand inside deeper. She groaned out again, a second time, when the tip of her middle finger hit the little rough spot on the front side of her slick canal, just behind her belly, the g-spot, and she started to breathe faster and bend her knees a little deeper and fall over forward a little, her breasts spilling down and hanging beneath her, firm and full. She wished Chad could turn around and see her like that. See how hot she was and how hot he was making her. That wouldn't break any rules, would it? If she opened her door wide and called to him and let him watch her like that, like she was watching him? She held her finger against the little rough place and started grinding her hips and her ass and her pelvis harder as she spread her feet a little wider and almost squatted down on her hand, just holding it there and riding it so hard that her wrist started to hurt and her crotch was dripping. Her little rough spot felt wet and firm, like the roof of her mouth when she was sucking on a piece of rock candy or something, sweet and sour. She was shivering all over and her pelvis went into spasm and her whole body felt hot and alive, like an electric current was shooting through her, and her wrist and forearm were hurting so bad she thought she might have sprained them. She held herself hard against her hand and bucked her hips as wave after blue wave rose deep inside her and travelled up the whole length her and crested at the crown of her head and broke all around her in warm foam. Chad's cock was pulsing inside Ellen and her pelvis was shaking and Kate didn't think it would ever stop. And he pulled it out slowly and his thick seed just flowed right out of her, painting her red lips and the inside of her thighs with a hot, white coat, and then dripping down her crack across her anus and making a puddle on the floor. The next thing she knew Chad was on his back against the wall with some pillows propped up behind him and Jess and Ellen collapsed in little heaps on either side of him in his strong arms while his chest heaved. Kate was standing there looking right at him and panting and kneading her breasts slowly and her boy shorts were around her ankles and her thighs were glistening with her juices. He was looking right at her too. She was pretty sure she was in shadow but she took a quick step back to make sure as Chad closed his eyes and started to stroke himself idly. Kate pulled down her shirt and pulled up her shorts and fell face down on her bed, dead asleep. Now it was morning and she was in child's pose bending low toward Chad so that the top of her head was almost touching his. He'd finally gotten the hang of the motion and the breathing in cat's pose and it was good to feel his shoulders and his stomach when it clicked for him and he started to relax and enjoy it. Kate was relaxed and focused and she felt calm. She was breathing in smoothly and holding it for an instant and then just letting it all go. She was maybe going to have to change her rule about not making out with Chad, and maybe even her rule about keeping her hands off his cock. She was his Professor and he was her student and that still meant something. They couldn't do whatever they wanted. They couldn't just march back to her room right now and fuck each other senseless the whole morning and just see where it led, which was kind of what she wanted to do if she was honest with herself. And definitely what she would do in an ideal world. Where she was his yoga teacher, say, instead of his professor, and he was some hot young guy she happened to be working with, her client, who seemed interesting and fun and into her. Still, he was just a kid and she didn't want to complicate her life with all the emotions and problems she'd have to deal with eventually when she had to stop fucking him and go back to her husband and make a baby with him, which was what she'd made her mind up to do, if he met her conditions. She would call him in a few days as planned and lay them out for him and agree to take him back. And then she would come back to the lodge and the mountains and finish her research. She needed to feel calm and fulfilled and inspired if she was going to do that work well. And to feel that way she was going to have to figure out a way to pleasure herself with Chad without crossing the line. Otherwise something bad would happen, if she stayed this out of control. He would catch her watching him, one of these nights, or she would wake up at the swimming hole one of these days, after teasing him too much, and he'd be right on top of her, and there would be no way to stop what happened next. She needed to find a way to get on top of her desire for him, to control it and ride it out. She was going to do yoga with him in the mornings and try that for a while. And maybe she'd massage his shoulders at the swimming hole later today, like a yoga teacher might after a hard session, and maybe he'd massage her. And maybe she'd want to be held by him then, and to fall asleep with him in the grass. And maybe when she woke up she'd want to kiss his neck and rub her body against him and feel his cock get long and stiff between them. Maybe that would be allowed under the new rules. Kate and Chad were sitting cross-legged now and facing each other and breathing in and out. She looked at him and smiled and he smiled back. Part 2 It was sheer chaos in M group when they finally found it. It took longer than normal because the chimps had gone deeper into the forest, up the mountainside, to try to escape the rain yesterday. The air was still heavy and humid and Kate and the kids (Chad, Courtney, and Ellen) were exhausted again from the long hike up from the lake. She and Chad were squatting close to each other, and sweating, and breathing hard, and watching the chimps with rapt fascination. The challenges between the aggressive males were flying fast and furious. The "pink lady" was in heat still and driving the males wild with lust and anxiety, but worse than that one of the older females had come into estrus too and her swollen pink sex skin was the center of everyone's attention, chimps and humans included. She was probably the second most popular female in the group after Mahalia, Kate guessed. She was not quite as old (maybe 28 years old) but her body was soft and curvy like Mahalia's and she had a serene and confident air about her. She was a female who knew she could make beautiful baby chimps that would survive and grow up to be strong, maybe dominant. And the males knew it too and they wanted to empty their seed inside her so badly that they would maim or even kill any male who stood in their way. They wanted it to be their genes in the baby that she would carry and nurture and raise. The stakes were much higher now that she was in heat and the tension and violence were at fever pitch. You could feel it in the atmosphere. So far she'd only been mounted by one male, who seemed the best bet to establish himself as the new alpha. He was sticking close to her and fending off challenges from the other two aggressive males left and right. Everyone once in a while he would raise his fists and beat one of the other males or bare his long fangs at him. And when they retreated to gather their courage again or lick their wounds he would hurry over to the mature female and grab her from behind and take her. But the whole time he had his eye on Brad and Mahalia too. Brad kept drifting casually over to the edge of the little clearing where the group was and calling out to Mahalia and gesturing to her to follow him into the forest. And the new alpha was worried that maybe she would. She wasn't in heat yet, but Kate's guess was that she usually came into estrus soon after the other mature female, and that the males remembered this at some level. He didn't want her wandering off now with her young guy friend who was luring her so skillfully with food and grooming. He wanted her close to him when her sex skin flamed out. He wanted her in his domain. A couple of times when Mahalia stood up and wandered over toward Brad the new alpha charged right over to her and raised his fists and kind of herded her back over to where she'd been sitting. And every time he did the other two males would come closer to the mature female in heat and start displaying their red penises. The new alpha would charge right back over and back them away from her. He looked frantic with anxiety and desire. Part 3 As soon as they got to the swimming hole Ellen and Courtney jumped straight in without taking off their tank tops or their running shorts or anything. Chad slid the pack off his shoulders and laughed and when he turned toward Kate she was laughing too and sliding her pack off her shoulders. Jesus she looked good doing it. Kind of shimmying her shoulders as she arched her back and stuck her chest straight out and shook her breasts a little too. She was wearing a loose grey tank top and her black yoga pants and all morning Chad had been dying to see what she had on under there. He'd been watching her ass the whole way up the mountain. And the whole time they were observing the chimps he'd been watching her face too, holding the camera in front of him, trained on M Group, while he stole glances at her squatting on her haunches and lost in her thoughts. Christ she was beautiful when she was in her element like that, in her zone. He could tell that she was fascinated by what was happening with the chimps and he very much wanted to know if it was for the same reasons as him. Because even though he knew it was kind of twisted and wrong, Chad was finding the whole atmosphere of the place and the group today kind of strangely intense, kind of hot almost. That was partly because he was so keyed up and crazy from his little yoga session with Kate this morning, true. That had been really something. She had to know that it was impossible for him be in those positions with her, dressed the way they were, without picturing having sex with her the entire time in vivid detail. And he was pretty sure it was the same for her. But the whole time they had to pretend that this was the farthest thing from their mind, or that if it had crossed their mind that it was just a fact of life and not a big deal. But it was a big deal. It was maybe the most important thing that had ever happened to him. It was maybe the most important thing happening on the planet right now. He didn't know why and he didn't care. It just was. There was something so gripping about all the tension and aggression and anxiety between the males, and all the raw desire for the new mature female who'd just come into heat. All of the chimps wanted to mate with her right now very badly, because they all wanted to survive in the most basic sense of the word. They were all mad with the desire to pass along their genes. And they felt that way because nature had designed them in a way that made it feel so necessary and good to do that, and so unbearably painful not to. They had no choice. The new alpha was practically losing his mind because he had to mate with the younger mature female as often as possible right now when she was primed, but he also had to mate with Mahalia soon and so he needed to keep her close. He needed to keep her close because she was very beautiful and she always made beautiful babies. And in a week or so she would be in heat and her backside would be the center of the world. Part 4 Kate laid on her back on her towel on the grassy slope with Ellen and Courtney to the right of her and Chad to the left. He was on his side looking at her and his hand was playing with the wet grass between them. She knew she looked good in her navy blue bikini with the little sport bra top that made her breasts sit up high and full on her chest, and the tiny little bottom that showed off her hips and ass. The suit was practical and sensible and anyway she was proud of her body. Chad could look at it as long as he wanted. It was only natural and she wanted him to. Courtney sat up suddenly and held her knees to her chest and started talking. "Why are you studying chimps this summer anyway? Why aren't you studying bonobos?" Kate turned and looked up at her. Her new short hair cut really looked nice on her now that her face had some more color and her blonde dye job was growing out and you could see her dark roots. She was a very handsome girl. "Well, for a lot of reasons, why do you ask?" "I don't know," Courtney sighed, "I guess I just wish we were studying bonobos. The chimps are just so depressing somehow. Almost sad. I mean, why do the females just sit there and wait for the males to decide everything! Why don't they bond together and take control of the situation or something, or at least have some kind of role in it! I mean why don't they do something. And why can't we be studying the kind of female apes who don't just sit around and get dominated." Ellen was laughing and Kate was too. "I know what you mean," Kate answered, sitting up and holding her knees in front of her and smiling warmly at Courtney. She really liked her and she would make an excellent graduate student. She could remember feeling just like that. Advanced Primatology Ch. 07 "It was Brian's idea, actually. And it was a good idea. It's just that in the primatology world chimps are kind of the stars of the show. A lot of primatologists don't even know about bonobos yet. So if you only do research on them it's hard to get it published in big journals. And that's what you have to do to get tenure and have your own lab and all that good stuff." Courtney and Ellen were paying close attention and nodding. "I want all that stuff very badly and it's a very simple equation. To get that stuff I have to make male scientists care about bonobo sex and reproduction, which females dominate. And to make them care about that I have to show them how it connects to chimp sex and reproduction, which males dominate." Courtney was shaking her head now. She didn't want to hear it. "But why are all the male scientists so obsessed with chimps in the first place! It's just so frustrating." Kate smiled and laughed. She recognized that righteous anger, and she admired it, though she didn't feel it in quite the same way as Courtney any more. "It's partly because bonobos were only discovered pretty recently," she answered thoughtfully. "But I think it's also because the chimp world is more like the world that male scientists want to live in themselves, more like what they think the world should be, naturally. And I can't really blame them. I'd be lying if I pretended that's not part of the reason I'm so interested in bonobos. I think our world should be more like theirs." Courtney snorted and smiled. Ellen was nodding and looking serious. Now she jumped in. "But the funny thing is that the male chimps seem so miserable too. I mean, it looked like they were all in serious pain back there. They wanted to mate with that mature female so badly it looked their brains were about to explode and their penises were about to fly right off them." "It's true," Kate laughed, "it's a smart thing to notice. Lots of studies have shown that bonobo males are actually way calmer and less stressed out than male chimps, including the alpha. Which makes sense when you think about all the reliable sex they get in all those exotic positions!" "Then why don't the female chimps do that too?!" Ellen laughed, but with real frustration in her voice. "Why don't they just bond together and gang up on the males one by one and just screw them into submission with new positions and tongue kissing and oral and just take shit over!" "I don't know," Kate shrugged and laughed, "I don't know sweetie. But I do know one thing. The most interesting thing happening with those chimps is what's going on between Brad and Mahalia and that's what I want to understand. That's the story we're trying to tell." She lay back beside Chad and turned on her side toward him and smiled. He was lying on his stomach now and his head was turned toward her. He opened his eyes and smiled back. "How are you feeling, huh tiger? Did those stretches help this morning?" "Pretty good actually. Thanks. That cat pose was tricky at first but it really loosened up my back. My shoulders and neck are still pretty sore though." Kate nodded seriously. "That's good. That's how it's supposed to work. It's almost like a gentle massage really. But I can see that your shoulders are still tight just from the way you're holding them. All hunched up like that." Kate paused and considered her neck sentence carefully as she eyed Courtney and Ellen, a little worried about how they'd react. Then she kept right on going. "How about a little back rub, huh tiger? How about I work out some of those kinks for you? I took some classes back when I was doing my yoga certification and Professor Phare tells me I'm still pretty good with my hands." She had a little sparkle her in eye as she said it, almost mischievous. Chad turned his head up toward her and paused for a split second and then nodded and smiled. "Sounds good. Thanks. I'd like that." Kate sat up and moved over to him and straddled him with her knees. Courtney and Ellen were watching her curiously. She blew on her hands and rubbed them together fast until they were warm and then she leaned forward and spread her hands wide and started kneading Chad's shoulders with her palms and fingers, slow but strong. Courtney made a sign to Ellen and they both stood up. "We're going to get going down the mountain ahead of you guys, okay? We were hoping to have time for a snorkel in the lake maybe." Kate nodded at them and went back to work. She loved the feel of him. He was so strong and packed with muscle but he was so tight and he really needed this. She could tell she was hurting him a little as she leaned forward on her hands and kneaded him deeper with her fingers and palms, not worrying when her nails dug into him once or twice and he winced out loud. She had to hurt him a little to get the job done, she laughed to herself. This was going to be fun. She was going to really enjoy it. He was already starting to relax and his breathing was getting smoother and she was pleased with herself for doing such a good job. That's what this was, really. It was like she was his personal trainer, his yoga instructor, and he was her hot, fun client and they had just started "working together" and it still felt new and exciting. She locked her elbows and extended her forearms straight out and put her whole weight on her hands. Chad grunted at first and then relaxed as she started rolling his shoulders with her fists. She needed to really work him hard at the beginning so he'd relax under her hands and stop resisting her. Then she could start with the more delicate stuff. For now she just needed to roll his shoulders slow and steady with her full weight on her hands. It felt wonderful but she really wished she'd brought some oil with her and maybe she'd do that tomorrow. She was leaning into him with her palms and caressing him with her fingers and he was getting more and more relaxed. She'd already decided that this would be a regular thing until his shoulders were better and her job was done. He looked wonderful with his shoulders and back spread out under her hands like that, and with his muscles rippling. And he felt wonderful too. She had her hands a little lower on his back now, about mid way down his spine, and she was leaning forward on her hands and then pushing them slowly upward to his neck and then caressing it with her fingers before she leaned back and started the whole motion all over. His whole back was so defined and she loved the pattern of the tiny ridges and muscles all over it, and she loved the way the patterns shifted when her hands pressed hard into him and rubbed him and the muscles softened and gave way. He was breathing out more and more deeply every time she pressed on his upper back now, working up from below, almost sighing, and she could feel that he was relaxed enough now for her to work the smaller muscles around his spine. She scooted her knees forward a little and sat back until her ass was resting on his ass. It felt warm and firm. She put her hands straight down between her legs and started working his lower back just like she'd done with his shoulders, but a little gentler, leaning forward and pressing down on the base of his spine right where it met his tailbone and then raising her ass up a little before she sat back down on him and pressed her forearms and hands down firmly again. She had a nice rhythm going right away and she remembered how good this part always felt, for her and the guy. It was pretty much the same motion she'd be using if she was on top of him in a different way, she couldn't help thinking. If he was lying on his back instead of his stomach and if her crotch was resting on his cock now instead of on his ass, which still felt pretty good really. She wondered if he was hard. She was still so keyed up from copping all those of feels of his stomach and chest during their yoga session today and the feeling of being on top of him like this, and the feel of his hard body in her hands, had her jumpy with excitement. She had a vague memory of watching some video with Brian where a guy was getting massaged by his stepmom or something, who was maybe a masseuse for a living, and at one point he turned over and she started to massage his stomach and chest while she ground his cock through her yoga pants and the towel around his waist started to come unwrapped. She remembered liking that clip. She was wearing a top pretty much like the actress was and she remembered how she and the guy had gotten more and more excited, and they'd tried to ignore it at first but eventually she was rubbing her yoga pants against his naked shaft and they ended up fucking long and hard and every which way. Kate was working all the way along Chad's spine now with little butterfly strokes, taking her sweet time with the base of his spine where it met his tailbone and then moving up a little and taking her sweet time there, vertebra by vertebra. She kept rising off him a little and then sitting back down, and she was really enjoying herself. But once the thought got in her head she couldn't stop wishing for something more. She couldn't stop wishing that there was something long and hard underneath her for her to sit back down on and grind against a little. The massage was for her as much as him after all and she needed to please herself too. She started arching her lower back a little and even angling her pelvis in different ways and rocking her hips to see if she could get a little friction going that way between her crotch and the slope of Chad's hard ass. He was having trouble letting go while she worked his lower back like this and he was clenching his cheeks a little, not that Kate minded at the moment. She was clenching her thighs a little too and her cheeks every time she sat down on him. She kept working up the sides of his spine and rubbing her crotch against him in subtle ways and after five minutes or so she'd gotten pretty worked up. He was lying totally still and relaxed now and from the way he was breathing and the angle of his head she thought he might even be asleep. She knew it was insane but she'd been wondering for the last few minutes whether she could actually get herself off this way. She really wanted to and she was pretty sure she could. Especially if she gave herself a little boost now and then like she was about to do now. He was probably asleep and even if he wasn't she'd be quick about it and he probably wouldn't notice. She took her left hand from his back, about halfway up his spine now, and reached between her legs. She rose up and leaned forward over him while her right hand kept massaging him and she worked the fingertips of her left hand under the waistband of her suit and down into her dark curls. She kept on reaching and when her fingers found her moist lips she spread them a little and stuck her finger inside to get more of her juices. She was definitely wet. She stuck two fingers inside her and used them to coat her lips and clitoris all over, getting them nice and slippery. Her nub was already hard and swollen and sticking out and when she flicked it a few times it felt dangerously good. She didn't want to just start fingering herself to orgasm right then and there on top of him. She didn't want to be obvious about it. She just wanted to give herself a little boost and then go back to the "real" massage and see if she could get herself off that way while she did her job for Chad. She was his trainer and he was her client. She took her hand out of her suit bottom and started massaging him normally again. She was leaning forward over him further now and both hands were working the tops of his shoulders, right where they met his neck. She got nervous that maybe he could smell her juices on her hands and she pulled them back quickly. He was totally relaxed now and he was almost definitely asleep and it seemed like the "official" massage should probably be over. But Kate wasn't quite ready to stop. She wasn't quite where she needed to be to do what she wanted to right now, which was to collapse on her side right next to him and maybe throw her arm around him, and maybe her leg too, and fall into a deep sleep for as long as she needed. To do that she needed to be more relaxed. She kept her left hand on his shoulder and moved her right hand to the small of his back, just above the waistline to his long trunks. She was wondering if she could angle her hand just right, and maybe stick out her thumb just so, and maybe ride against the fat part of it a little when she leaned forward and did that little thrusting movement with her ass and hips, rising off him and sitting back down. She tried it a few different ways and before long she had it working just like she wanted. She was still massaging him but she was definitely getting a little boost now from the contact between her thumb and clitoris and it might be just enough. Her wrist was killing her and her thumb was bent backward almost painfully but that just made it feel better and hotter somehow. She was picturing him on his back underneath her while she massaged his abs and his chest. He was looking up at her almost pouting and breathing hard and she was looking right back at him the same way and her heart was racing. She had her wet folds around his long hard shaft and she was rubbing the whole length of him back and forth slowly. They both knew what was going to happen and they both wanted it and it was the right time. She rose off him a little higher and leaned forward and he knew just what to do. He grabbed his cock by the root and held it for her at just the right angle and smiled sweetly, but a little cocky too, and she leaned back and eased him inside her, inch by delicious inch. He was all the way in. He was so thick and hard and he was touching every nerve she had and switching it on and off and on again as she started to bounce on him a little. She kept him shallow at first, just his fat tip and his first inch, but pretty soon she was sitting straight up and bouncing a little harder and taking more and more of him inside and his eyes were closed. And her eyes were closed too so she could feel him better, so she could shut out everything else around her except his hard cock sliding in and out of her wet canal and the way the friction between them was sending hot sparks all the way through her and they were marking her feel hot all over, almost burning her skin. His shaft was naked and his balls were heavy and full and she was leaning forward and taking him longer and deeper with every stroke. They were panting and groaning and she had one hand spread flat on his stomach and the other hand in her bathing suit and she was fingering her slick knob. She was sitting straight up and rising almost all the way off him and then just dropping herself down on him and taking more and more of him with every plunge. She felt him bottom out once or twice as his fat tip hit her cervix, a little hard maybe, but she loved it anyway. She loved the feeling of him like that, and the thought of it. He was so deep inside her. He was filling her completely. She was fingering her clit and bouncing on his cock and her other hand was flat on his stomach and it was tensed all the way. She'd never felt anything so hard and powerful and solid in her life. She held him all the way inside her and dug her nails into his stomach and started circling her hips against his fat tip so it was massaging her cervix. Her nipples were hard and her pelvis was shaking and her clit was hard too and she was grinding it with her hand. And then it started and she didn't want it to ever stop. It was like she was having two orgasms at the same time, maybe three, right on top of each other. One of them was centered on her clitoris and it was the one she usually had, but longer and harder than most times and breaking over her in little waves. But another one was happening deep inside her, and she'd only had it once or twice before. The walls of her pussy were contracting around Chad's cock and holding him inside her and almost milking him while her cervix gave little warm, wet kisses against his mushroom head. She was shaking and gasping and bouncing up and down on him, just a little, just the tip of him, but quick and hard too. She felt his cock get fatter and harder and hotter inside her, if that was even possible physically, and he started to groan a little louder and his heavy balls pulled upward and his shaft was heaving and pulsing. She sat down on him all the way and held him as deep as she could and waited for him to explode inside her, white and hot, and when he finally did it felt like a warm white wave of cream and foam and it was filling her up and then she exploded too. Her nails were digging deep into his stomach and her hips were rocking and her ass was in spasm and she felt a warm glow of happiness and pleasure start spreading from the little place between her groin and stomach, just behind her belly, until her whole body was shaking. And it kept on shaking and her mind went blank and the next thing she knew she was still on top of him and he was still hard inside her and she felt relaxed and spent. She pulled herself off him and collapsed next to him in the grass and pretty soon they were both asleep. Part 5 Kate had given everyone the evening off and they were all enjoying the twilight and the cool breeze down by the lake. Most of the kids, including Chad, were in the water snorkeling in the little shallow spot where the fish swam in to feed this time of day. She was sitting on a beach chair next to Jess and looking out over the wide blue lake as the moon cleared the horizon and the water and sky began to darken. It was a very beautiful moon this evening, she noticed. A perfect half circle. It had been a great day and she was savoring the moment. She was sure that her research with the chimps was going to work out. Her mind was relaxed because she was convinced now that Brad and Mahalia were going to go "on safari" soon, and there was a very good chance that Mahalia would get pregnant by Brad, and maybe she'd even give birth to the next alpha male. And probably Kate's paper about it all would be a huge success. Her body was feeling calm and satisfied too. She smiled and shivered a little remembering how she'd been "riding" Chad at the swimming hole that afternoon, how she'd figured out a way to get herself off with him, hard, and even to sleep and cuddle with him after, without crossing any of the lines she needed to maintain to be a good professor. To the contrary, it was all part of what she had to teach him, what he needed to learn to fulfill his potential and reach his goals in life. Who said that her lessons couldn't be about his body as well as his mind? If he was going to be a good primatologist he would have to learn to balance the two and that's what Kate, as an older and wiser and more experienced woman, was trying to teach him with all the yoga and massage. And who said she couldn't enjoy herself physically and emotionally while she taught him? It was a ridiculous idea, probably thought up by some repressed man somewhere back in the dark ages who was probably screwing his students every which way on the sly while he wrote down his stupid laws and passed them down to her. Kate was Chad's teacher, and he was her student, body and mind, and that was the only kind of teaching that mattered to her. She stretched herself out in her little navy blue bikini with the sporty cut that looked so cute and sexy on her and that Chad had been enjoying so much a couple of hours ago when it was just the two of them. She would wash it in the sink back at the cottage tonight and let it dry on the line. And she'd wear it again to the swimming hole tomorrow because she wanted to make him happy. She wanted to please him. Advanced Primatology Ch. 07 Part 6 Karin's mouth was dry and her heart was racing. She was in her tiny bedroom digging through her big backpack for the little hard plastic pink case in the bottom where she remembered packing it. Hiding it really, if she was honest with herself. She hadn't been completely open with Kate the night before when she'd told her about her "bucket list" with her fiancé and how hot he'd been when she told him that she wanted to put one of her students (Chad) on the list. And she hadn't been completely honest with her husband when she told him about which students she "knew" would be on the trip, but hadn't told him about Chad. She hadn't been lying exactly either. She didn't know for a fact that Chad was going to be on the trip before the group met at the airport and she finally saw him, looking so hot and sure of himself with his backpack on his shoulders and the chest strap buckled and making his pecs stand out in his tight shirt. She hadn't known it for a fact but she had a pretty good hunch. She'd overheard a conversation between Jess and another grad student in the lounge in the anthropology department and they'd been laughing and joking about how fine some guy was (a soccer player with deep blue eyes) and how much fun the trip could be now that his study abroad funds had come through and he was definitely going. And she hadn't been honest with Jess the night before when she'd asked to borrow her diaphragm (what a fucked up idea!). She hadn't been honest because she HAD brought it with her even though her future husband was on the other side of the planet. She'd taken a deep breath and packed it in the bottom of her backpack at the last minute. She took another deep breath and looked at the little night table next to her bed where she'd lit a scented candle and placed two bottles of scented oil. She was standing there in a pair of lacy white panties and a tight white tank top with no bra underneath and the whole outfit had kind of a bridal look to it in a way that was making her feel excited and happy and jittery with anticipation. Like what was about to happen was all just part of her wedding ceremony or something, in a twisted way. Part of the long, deep, difficult process of leaving behind her life as a single young woman and committing herself to one man, her fiancé Rick, for ever and ever. When she came back from the trip she was going to marry him and give herself to him body and soul. She took another deep breath and opened the little drawer to the night table and placed the pink case inside it and the little tube of spermicide too. Then she closed the drawer softly. She bent over and picked up the short pink skirt from the bed where she'd laid it out carefully and wrapped it around her hips and tied it. She looked down and smiled. Nice, she thought. It was a little sheer and you could see the white panties through it. Her knees were shaking as she took a few wobbly steps toward the door to her bedroom, and out through the common room, and down to the lake to find Chad. She felt like she was walking down the aisle. Part 6 Chad was standing knee-deep in the shallow water and looking up toward the women's cottage when he saw Karin walk out the front door, and down the steps to the porch, and down the green slope toward him. Her breasts were bouncing a little and her hips were swaying and she looked like a vision from another world, with her dark skin and her kinky hair and the little pink wrap skirt and her nipples through the white tank top. He'd always heard that expression about having your "heart in your throat" but he'd never known what it meant until right then. It was kind of painful, actually. He felt an ache in his chest where his heart usually was and an ache in his throat where his heart was lodged at the moment. He wanted to swallow but he couldn't. He knew it was crazy but he felt like he was standing there dumbstruck at the front of a church, near the altar, and watching his bride walk toward him. She strode right down the slope to Jess and Karin and then she bent down and whispered something in Jess's ear. And then Jess nodded and Karin stood back up and scanned the lake for Chad and when she found him she smiled and waved at him and made a motion for him to come over to her. He took a deep breath and walked right over to her, a little slowly, enjoying the buildup. When he got to her she smiled at him and grabbed his hand and turned and led him up the grassy slope toward the women's cottage. The sun had already set behind the green mountains and they looked otherworldly somehow with the moon lighting them up now and the purple sky behind them. He was watching Karin's ass sway in the little pink skirt and he could see the white panties underneath it and maybe a little lace at the edges. She led him up the porch stairs into the common room and then straight through to her bedroom and slid the door closed behind them. There was a scented candle lit on the little night table next to her bed, and two bottles of oil. Karin dropped his hand and turned to face him and smiled. She untied the little wrap skirt and let it drop from her hips to the floor. She smiled at him a little shyly and a little saucy too. "Close your eyes for a second, okay?" He did as he was told. When he opened them she had peeled off the white tank top and she was standing there facing him and breathing a little harder and holding her forearm across her full breasts. Her kinky hair looked dark and lustrous against her bare shoulders. Chad's mouth was dry and his heart was racing. "Aren't you going to say anything, you big dummy?" she teased him, blushing. "You look amazing," he told her, his voice shaking a little, and it wasn't an act. She smiled and dropped her head to the side and moved over to the bed and lay down on her stomach on the white sheet in her lacy white panties. Chad was thanking his lucky stars that he'd taken that gut course on exercise science his first term at UNC with all the other dumb jocks. That was before he'd realized how smart he was, and how much he liked being smart. But the course had been worth it! There had been a unit on massage and now he was very good with his hands. And that cute little kinesiology major who he'd started banging halfway through the semester had been into tantric and she'd taught him a few good tricks. Chad reached for a bottle of oil and drizzled a generous amount on her shoulders and upper back in a big s-pattern all over her. Then he leaned forward on his hands and started working her hard and deep right away, not enough to hurt her, but enough to loosen up the big muscles in her upper shoulders and back and neck that were always the tightest and that he could see were tight in Karin just from the way she was holding herself. She relaxed right away and gave him a little sexy moan. "Ummmmmmm. That's so nice, baby. That feels so good." He worked her like that for a while. She was a complete vision spread out under him like that. Her back and shoulders and sides were so strong and toned from all her tennis and cross-fit but she was so fleshy and soft in all the right places. She felt so sexy in his hands. He drizzled some more oil on her lower back and went to work on the delicate muscles along her spine and along her ribs and even up to her armpits and along the sides of her breasts. Her ass looked unbelievable in the lace white panties that were cut square across her bottom with her ass cheeks peeking out the bottom and making him hard already they looked so cute and plump. He would definitely be fucking her from behind at some point tonight. Of that he was sure. Karin was moaning for him and wiggling her ass a little and Chad could tell that it wouldn't be long before they dropped the whole pretense of a massage and started to have sex for real. He scooted back on his knees and brought his hands to her butt and started to knead them strong and hard. Then he reached for the oil again and drizzled it all along her upper thighs, careful not to stain her panties with it. Then he took his fingers and palms and started to spread the oil smoothly until it coated the backs of her legs entirely and even the inside of her legs too. Karin was moaning a little louder and telling him how good it felt and wiggling her ass a little more. Then she really surprised him. She was laying on her stomach and she brought her hands to her breasts and held them and then she just rolled right over and lay on her back beneath him with her knees bent and her legs spread and her feet flat on the mattress. She was looking up at him with her tits in her hands, breathing hard, and he could see her dark curls through the lace panties. "I want you to massage my front too, okay?" Chad nodded down at her. It was stupid but his legs were shaking like crazy. It felt like he had never seen a woman on her back like that for him before, and when you really thought about it he hadn't. She was just a few years older than Jess but it made all the difference, in her body and her personality and her whole way of being. He was pretty sure that he'd never felt that much sheer physical desire for a female body before. He reached for the oil again and drizzled it all over her stomach and her strong quads. He smiled down at her sweetly and started rubbing the oil all over her slow and smooth. She was breathing a little faster and her eyes were half closed and she was watching every move. When he had her good and oiled up he started working his way up from her feet to her calves to the muscles around her knees, to her quads and hips. He felt her whole lower half just relax and melt in his hands, inch by inch. And then he worked the sides of her torso with his fingertips while he pressed the muscles of her abdomen gently with his thumbs and kept inching his way up. His hands were just beneath her breasts now and she was breathing harder as he probed the tiny muscles in her rib cage and around her solar plexus. She bit her lip and pouted at him a little and then she smiled and moved her hands away from her breasts slowly. She stretched herself out long and slow and sexy on the white sheet. She reached her arms up toward the headboard and arched her back and stuck her chest out like she was yawning or something. He'd been expecting something spectacular but the sight of her white round juicy breasts finally naked for him, and displayed for his pleasure, went beyond his wildest expectations. They were hands down they best he'd seen. In a flash his hands were on them and he was massaging the edges and working his fingertips toward her nipples. And pretty soon he had his hands spread wide around her breasts and her nipples were in the spaces between his middle fingers and his pointer fingers and he was squeezing them tight once in a while as he massaged her chest all over. She was really getting into it and he thought she might cum for him right then and there. He'd head of that before but he'd never seen it. Then she surprised him again. She reached down for her waistband and lifted her ass off the floor and smiled at him archly. She slipped the white lace panties right off her in one smooth motion. Then she dropped her ass back down and spread her legs with her hands. Her knees were still bent and her feet were still flat on the mattress. "I want you to massage me inside too, okay? Is that okay if we do that?" Chad smiled at her and nodded. He lay down on the mattress next to her and then he reached his left arm around her and turned her toward him a little and held her chest tight to him, looking right in her eyes. Then he reached his right hand down to her wet crotch and stretched out his middle finger and parted her wet folds and slid it right inside her with his palm facing upward, as deep as he could get it. She was so warm and wet and slippery and Chad reached all the way in for her smooth cervix and then pulled his finger out a little and felt for her little rough wavy spot just behind her belly. He started curling his fingertip toward her upper wall, slow and steady, over and over, while he kept looking down at her and holding her tight. She looked up at him and parted her lips and he knew it was time to lean down and kiss her full on the mouth. She had a beautiful mouth, with beautiful full lips, and it was wet and warm inside too, just like her pussy. He kept curling his fingertip inside her, like her g-spot was a little pussycat or something and he was trying to lure it over to him for a saucer of milk. Her stomach was relaxing and her breath was getting smooth and shallow. He looked down at her and smiled and kissed her full on the mouth again, with a long loud wet smack on the lips. "Is that how you want it? Is that how you want me to massage you?" Karin nodded and blushed. "If feels amazing, baby. But I want to try something else, okay?" Chad nodded. Karin was blushing like crazy. She took a deep breath and bit her lip and kept right on going. "I want you to massage me with your cock, okay? I want you to massage me like you were massaging Ellen last night on the floor. I was waiting you for you all night on my bed but you never came in. I want you to massage me inside with your big fat cock now, okay? Just give me a minute." She didn't wait for an answer. She rolled over and opened the drawer in the little night table and pulled out a hard pink case and opened it. She pulled out a diaphragm and reached down and started positioning it inside her. "Turn around, you big dummy. Turn around and take your clothes off, okay?" Chad did as he was told. When he turned back around she was completely naked lying flat on her back on the mattress with her legs spread wide and she was blushing from head to toe. He knew what she wanted. She wanted to start nice and slow and simple in missionary and just take it from there. He knew why. It wasn't the best position in the world sensation wise, for him or her, but there was just something so hot about the idea and the look of it. There was nothing like the sight of a beautiful female just lying on her back like that and spreading her legs for you and just giving her body to you to ride it at your own pace and for your own pleasure. It always felt like a ritual almost, the way a woman told a man that they were about to cross a line together and nothing would be the same between them ever again. She'd been his teacher once, back in those long lab sessions beneath her white lab coat, but now she was naked in his arms with her legs around him and she was about to a woman who had fucked him. Chad was lying on top of her between her legs with his chest resting on her chest and his weight held on his elbows and knees. He leaned down and they started kissing a little wilder, their tongues slithering in each other's mouths. He brought his hand down to his cock and held it by the root and positioned the head just so. She was so wet and warm and he'd opened her up with his finger already and so now he could just slide right in, maybe three inches deep. Karin groaned out once, long and slow, and then looked at him and smiled. "Take your time, killer. We've got all night. Okay? She reached up her hand and pushed his bangs from his eyes and then she reached up with her mouth and kissed him full and wet, looking straight up at him as she brought her hand to his chin and started stroking his stubble, sticking her tongue out between his lips so he could suck on it a little. He was squatting on his knees between her legs with his legs spread wide and hers wrapped tight around his waist. She started rocking back and forth a little on the small of her back while she stroked and scratched his beard and the sides of his face too. She was kissing him with her mouth all the way open now and her lips wrapped around him and their tongues dancing. He could tell that Karin loved the feel of it. He knew he was handsome and strong and powerful but he also knew that his lips were like a boy's, so plump and red and beautiful. A lot of girls had told hi so. Karin let her head fall back a little so she could look at him, and so he could look at her. She was setting the pace and they were fucking slow and shallow and gentle but she was so wet and he was so hard and they could both tell than when it really started, when they were fucking harder and deeper and for real, it would be fantastic and they would both love it. And they both knew they would do it as many times as they could, all night long if they had to. "You've got me the whole night, okay stud. Go easy on a girl. It's been a couple weeks, okay? I haven't been fucked in a while." She was blushing a little and looking gorgeous and Chad leaned down and kissed her. "Poor thing. You must really need this, huh?" She was nodding up at him and rocking her hips and he leaned down and kissed her again. "Is this okay? Is it okay with just the tip like this?" He flung his hips forward just a little and fucked her a little deeper and her breasts shook a little and her eyes went wider. She was nodding up at him and holding his face in her hands and stroking his beard and rocking her hips. "And I can fuck you all night?" She was nodding and rocking. "You promise?" He flung his hips forward again and fucked her even deeper this time, just a little, and her breasts shook a little harder and her eyes flashed. She smiled up at him and groaned. "Uggggghhhhhh. I promise, killer. Ummmmpppphhh. You've got me all night." He was squatting on his knees again and looking down at her with her calves in his hands. She was a goddess. Her dark kinky hair was spilled out on the white pillow and she was looking up at him with her deep brown eyes and the lids were half shut and her mouth was open and she was starting to gasp and pant every time Chad thrust his hips. And her arms were framing the sides of her breasts and they looked so pale and firm and ripe, but soft too somehow and he was watching the little waves roll across them as he changed his angle and fucked her a little sharper, but still shallow. Chad looked down and watched his long shaft plunge in and out of her as she rocked her hips. Her hands were between her legs now and her fingers were reaching through her dark curls and toward the space where his pubic bone met hers. He looked her in the eyes again. She was smiling at him almost wantonly and pushing her tits together with her arms and arching and her back and sticking her chest out at him. Her nipples were hard and her breasts were really bouncing now. "You like the way that looks, huh stud? You like the way a real woman looks when you fuck her? Chad looked down at her and nodded slowly and leaned forward onto his fists. It changed the angle of his hips and pelvis and cock again, just like he planned, so it was curved more toward the front of her, and a just a little to the left, toward that little rough wavy spot just behind the belly in most girls. That hot little tantric chick had taught him how to find it. Karin's eyes went wider and her stomach tensed and she kind of up sat up a little toward him. He knew he had her right where he wanted her now, right where she wanted too. His cock was hitting her g-spot over and over, maybe three inches inside her, and things were about to go to a whole new level. And they both knew it. "How about tomorrow night? Huh Karin. Can I fuck you all night tomorrow too?" He was leaning forward on his fists and looking down at her and smiling his sweet smile, but a little cocky too. He knew she wanted to say yes. Karin rolled her big brown eyes at him and then shrugged her shoulders in that cute way girls do that makes their tits shake and jiggle. "Maybe. I don't know. Maybe you can fuck me tomorrow." Chad smiled and laughed. "Maybe? You're not sure yet?" He was looking at her with his eyes wide like he didn't believe her and smiling at her sweetly, almost teasing her. Advanced Primatology Ch. 08 Karin stretched herself out naked on the white sheets and opened her eyes slowly. The sun was just coming over the horizon and light was flooding into her tiny bedroom. Chad was already gone, probably swimming laps and doing yoga with Kate, and Karin felt a little twinge of disappointment and maybe even jealousy. She'd been planning to wake up before Chad and clean him off slowly with a warm wet towel and then take him in her mouth and thank him properly for how wonderfully he'd treated her last night and how special he'd made it. She looked down at herself and smiled. She looked beautiful and she felt beautiful. Her breasts were full and ripe and they sat up high on her chest and bounced just right when a man put her on her back and fucked her, and her hips were wide and her ass was firm and juicy. She knew it looked amazing from behind. It was no wonder that Chad couldn't keep his hands off her last night, or his cock outside of her. It was no wonder he'd stayed rock hard for her practically all night long. She'd cum so many times with him inside her that she'd lost count. She was feeling rested and satisfied and eager for the day. She'd be in Kate's group with Chad and one other student today and she'd finally get to see Brad and Mahalia in person. Kate had told her last night. She needed another experienced set of eyes on the mature female chimp and the seductive young male. She was counting on Karin to be able to see things that she might have missed. She was going to have to be careful with Chad. She could see that now. She loved his hard body, and his handsome face, and his big cock, and he was the kind of guy that if they were the same age and she'd met him when they were both in college she might have ended up dating him seriously, maybe even marrying him. They would have had a good marriage! He would have kept her very happy, she thought, blushing a little as she remembered the feel of him, heavy and hard inside her, grinding and thrusting. She would spend one more night with him and then she'd thank him and give him a long deep kiss and end it for good. She'd expected him be a hot fuck, of course. She'd seen him take Ellen and Jess the other night when she spied on them through the gap in her door, so she knew he was hung and that he loved to drive women wild. She knew he had lots of experience. But still, she hadn't expected him to be such a skillful lover somehow, so attentive and responsive to her body and its desires. It was like he knew what she wanted before she did. They'd fucked so many different ways and he'd cum all over her three times, pumping liters of hot seed all over her stomach and tits and neck and even her ass and back and shoulder blades. Every time she was amazed by how happy it made her feel and how much she loved being covered by him like that. He was like some pagan fertility god or something the way he spewed seed all over her with his chiseled body and his square jaw and his tree root cock. She loved how thick it was and how much it seemed to fill her up and make her feel heavy and swollen inside. She smiled remembering falling asleep with him spooning her, and she shivered when she remembered waking up on her side with his naked shaft inside her. She didn't mind one bit. He'd treated her just right when she'd asked him to massage her, first with his hands and then with his cock, and now she owed him one. It was fine if he wanted to take her like that, while she was asleep, without even asking. He'd earned that right. She made him stop so she could put some more spermicide in her diaphragm (she was still wearing it like she was supposed to) and then she went right back on her side in his arms and spread her legs for him and watched him ease himself all the way in from behind. She loved the way he stretched her out like that. She loved how it looked and she loved how it felt and she loved the idea of it. She was wild with anticipation to be taken from behind by him because he really knew how to do that thing with his fat mushroom head and her sweet spot. She hardly ever came from penetration with her fiancé Rick but it seemed like Chad knew a dozen positions that were perfect for it if the guy had the right technique and the girl was wet and excited and making him rock hard. She was learning so much from him and her marriage was going to be so much better for it. She remembered him rolling over on top of her and laying her flat on her stomach and just shoving himself in again all the way and putting all his weight on top of her. He was grinding her slowly and angling the tip of his cock up toward her sweet spot while his hand reached around her and fingered her fat button until she started gushing and quaking all around him. That was a big one, she laughed, remembering how loud she'd gotten. Her mating call. It worked like a charm. Chad had been so patient and skillful the whole night up till then but she knew he was dying to fuck her hard and raw, and when she started crying out for him there was no way he could hold himself back. "Oooohhhhhh fuck. Oooohhhhhh fuck me. Ohhhhh fuck I love it when you fill me up like that." "Yeah? You want me to fill you up?" She did want him to, she had to admit, but she couldn't let him. She couldn't fuck him raw, and she couldn't let him cum inside her. But she could let him fuck her hard. "I want you to fuck me hard and then I want you to cum all over me, okay stud? I want you to fuck me hard with your beautiful cock and cum all over me, wherever you want." She was on all fours in front of him and he was on his knees behind her and he was fucking her so hard she thought she might pass out from how hot and tight his cock felt sliding against the walls of her pussy and how feverish it was making her. She knew she had a beautiful ass and she knew it looked big and round and lewd in this position with her cheeks spread wide and her rose puckering for him. And she could tell how much he loved it by how thick and hard he was getting inside her and by how powerfully she was being fucked by him. She loved it this way. She had her chest and shoulders and face on the mattress now and her back was arched so that her ass was held high for him. He was driving down into her over and over. It was like his cock was the root of a tree or something and she was the moist earth and he was extending and growing and probing down into her and then drinking her right up. She was cumming for him again and she could tell that she was about to pull him right over the edge of the waterfall with her, and they were about to drop straight down into the whirlpool, foaming and white. There was nothing she could do to stop it. There was nothing she could do on the wide earth except quake and gush long and hard around his shaft and pray that he'd pull out and spray his seed all over her ass and back. She couldn't do anything about it. She couldn't even really blame him if he did cum inside her. She couldn't really say she hadn't wanted him to, even made him do it in a way. Her pussy was contracting around his shaft, almost squeezing it like a warm hand around an udder or something, and he was all the way inside her. She had her face in the pillow and she was screaming out for him to fuck her just like that with his big fat cock and make her his. She felt a wave of relief and gratitude and maybe disappointment wash over her as he pulled out of her and she felt the thick ropes of hot sperm start lashing her all over her butt cheeks and back and shoulders. He was lashing her gently with his hot seed. He was painting her all over with white hot lines in an intricate pattern all over her beautiful backside and her strong shoulders and her delicate spine. And he was groaning and gasping out over and over and her legs and ass were quaking again just from the thought of how much sperm he was covering her with, and how much her body loved it. She was getting off just on the idea of how completely he was possessing her and her making her body his for as long as she let him have it. He collapsed on top of her and they lay there panting for a while and then she felt him get up and put his boxers on and walk out of the room. He came back in and sat on the bed beside her and started cleaning her off. She fell asleep with him washing her back with a wet warm towel. She was going to have to be very careful with this kid. Part 2 Kate was on her knees next to Chad down by the lake trying to show him cat pose again while the sun came up in front of them and she couldn't tell if she felt good or bad. On the one hand she felt safer and calmer with him now that he was with Karin, and that seemed like a good thing if they were going to keep working together as a team. She'd already felt comfortable with him because she'd overheard him telling Jess and Ellen the other night that he wouldn't let her cross any lines with him because he admired her so much and he knew how much it meant to her to be a good professor. That's why she'd felt comfortable enough to massage him the way she had at the swimming hole yesterday, and to "massage" herself to a nice hard orgasm on the sly while she was doing it to him. She knew she could depend on him to keep it within bounds, even if she couldn't depend on herself. And now that he was with Karin she felt just a little more comfortable. Karin was the kind of older woman that could really hold the attention of a young guy like Chad, that could really blow his mind with her deep, soulful nature and her hot thirty-year-old body in its absolute prime. She was glad to have Karin around to take care of him at night and take a little of the edge off for her so she could work with him during the days. But on the other hand Kate could feel that Chad's mind was elsewhere, probably still in bed with Karin and having fantastic sex with her, and it was driving her crazy. She wanted him here with her right now, body and mind, and it was starting to piss her off and even hurt her feelings the way his thoughts kept drifting back to Karin and her bed and her beautiful body. He was so much less tight today, so loose and relaxed through his back and shoulders and hips, and his body felt wonderful as a result. But she knew it was his night with Karin that had made him feel that way, and it was taking some of the fun out of it for Kate. She was only four or five years older than Karin, and they were both Chad's teachers, and neither one of them had tenure. And neither one of them was really married at the moment when you really thought about it. Karin was only engaged, and she had her fiance's permission to be with Chad anyway, and who knew what was going to happen between Kate and her husband when they finally talked and she started grilling him about his affairs and he started confessing. Why should Karin have all the fun? If Karin was going to have sex with him all night long then Kate deserved to have at least a little fun with him during the long, hard work days. She deserved to have his full attention. She was going to have to tease him a little for "revenge." Kate had her right hand on Chad's chest and her left hand on the small of his back as she talked him through the pose and helped him time his breathing. He was still having a little trouble with the rhythm and motion. She smiled to herself archly as she started scratching his chest, subtly, with the nails of her right hand, and stroking the little dark hairs on his pecs, and even touching his nipples once or twice with her fingertips. And she smiled a little wider as she brought her left hand to his backside and started squeezing his ass cheeks just a little, one after the other, and telling him to just relax and stop resisting and let himself go. He was exhaling slowly and she shifted her position and brought her left hand up between his shoulder blades and started raking her nails across the vertebrae of his upper spine. Then she reached up a little further and started scratching his neck. She brought her right hand to his stomach, and then a little lower, right over that spot between his belly and his pubic bone. She was sliding her fingers through the trail of dark curls that led down from his navel. She was marveling that he had such tight defined muscles even there, right down to the low waistline of his damp speedo. She felt his breath get smoother and stronger and she smiled inwardly to herself because she knew he was enjoying her touch, and she knew that he'd come back to her now, body and mind. She eased him back into child's pose and then she crouched down into the same pose right in front of him so they could relax together. They were rolled up in little balls and breathing deeply and just melting into the wet grass with the tops of their heads practically touching. After a few minutes she told him to sit up and they faced each other with their legs crossed, still breathing smoothly. Chad's hips had loosened up since yesterday and he had his knees flatter to the ground, and his groin was open wider, and his pelvis was thrust toward her a little more. He was sitting up straighter and higher and looking right at her. Kate was pretty sure she'd never been looked at like that before, and definitely not by a student, by a teenaged guy. He was right there with her, right there in the present moment, and he was enjoying her body. He was calm and relaxed but she could see that he wanted her very badly. And he looked very sure that he would have her when the time was right. Kate looked him up and down, not trying to hide it at all, and then she looked right back in his eyes and smiled at him. She wanted to let him know how much she was enjoying his body too. And then he looked her up and down too and it felt like his eyes were burning her from head to toe. He drank her right down in one gulp, from her face, to her neck, to her full breasts in the little sport bra bikini top that made them sit up high and full on her chest, to her toned, womanly abs and stomach and hips in the tiny bottom that showed them off nicely, to the place between her legs where her pelvis was opened wide to him and thrust forward a little as she enjoyed that warm glow of happiness and pleasure. After a while they stood up and stretched their arms over the heads, still facing each other, and then they turned together and walked back to the women's cottage to get dressed for the workday. Kate was feeling so comfortable with Chad, and so close to him, and she was wondering how far she could push the boundaries at the swimming hole later. She was wondering if she could even fool around with him a little, if it would help to ease the tension between them and help them work together as a team and get the job done. Maybe it would give Chad more confidence and make him feel appreciated and rewarded for all the hard work he was doing. Maybe there could be a few adjustments to the lesson plan, she thought to herself, almost laughing. Maybe there could be a new curriculum. Maybe Karin would "work" with him during the long cool nights, teaching him things about his body and about life, and maybe Kate would "work" with him during the long hot days, teaching him other things. Maybe she and Chad could wake up every morning and do yoga and then go out into the field and watch the chimps do amazing things that no one had ever seen before. And maybe later at the swimming hole, after they ate and swam and rested in the grass, maybe they could reward each other every now and then for a job well done. They were a good team. She liked mentoring him and being with him and he made her feel inspired and confident. They would make a good couple, she caught herself thinking, if he wasn't practically half her age and an undergraduate at the university where she taught, and where her shithead husband taught too. Still, if Karin could fuck him then Kate could at least make out with him and let him hold her in his arms. It wasn't that much different than doing yoga with him to help him relax and focus, or giving him a long massage in the grass, or giving him a big thumbs up when he did good job with the camera. She was his teacher and she needed to do special things with him to reward him and encourage him. He was a very special student who she was working closely with, almost as a colleague, and it made sense that they were getting more intimate with each other, mind and body, and it made sense if her rewards were more intimate too. Anyway she wanted to, and fuck her husband, and no one but she and Chad would ever know anyway. They were walking close together, almost shoulder to shoulder, and all of a sudden Kate elbowed Chad in the ribs and started teasing him. "You seemed a lot less stiff this morning, tiger. What did Karin do to you last night to get you all relaxed like that? It must have been something pretty special." Chad turned to face her and eyed her curiously. "Nice guys don't tell," he shot back, smiling. "Is that what you are? A nice guy?" "Sometimes." They were walking past the little thatched roof cabana down by the lakeshore and Kate had a flash of inspiration. There was something she really wanted to do to him. It wasn't dirty or anything but she didn't want anyone else to see and get the wrong idea. They were probably the only two people awake yet and it was the perfect time. She grabbed him by the hand and pulled him into the cabana and once they were both inside she stepped toward him, slowly, still holding his hand. She stepped right up to him, right into his body heat, until she was just a few inches a way from him. She put her hands to his shoulders and backed him against the wall. Then she held his hands again. She was looking up at him and he could tell that she wanted to say something, but she couldn't make herself say it. "What is it?" he asked her, almost whispering. Kate rolled her eyes and blushed. "It's stupid. Let's go." She dropped one of his hands and turned and started leading him out of the cabana. Chad took control. It was the right moment, though he hadn't been expecting it. He held her hand tighter and kind of swung her back to him, like a dance step almost. "It's not stupid. Tell me." He did that very nicely, Kate thought to herself, almost gracefully. The way he shifted their roles like that. The way he reassured her and encouraged her and promised to listen with his eyes. He knew what women wanted. He was so intuitive like that. She took a deep breath and stepped toward him a little and dropped his hands. She put her hands to his chest and pushed him back a little and looked at him seriously, blushing a little too. She tried to look him in the eye but she couldn't. She looked at his hard chest instead and lowered her voice. She inched a little closer to him. She was standing right in his heat. It felt so good and so right. "I want to ask you if I can do something, okay? But I don't want anyone to get the wrong idea, including you, okay? Can I ask you for something? Promise you won't get the wrong idea?" Chad nodded. "Promise you won't laugh?" Kate pleaded, a little girlishly, and loving the way it felt to flirt with him in that new way. Then she got serious again, "And promise you won't let it go to your head? I'm still your professor and you're still my student, okay? You're my best student. My favorite." Chad nodded again. He was playing it as cool and quiet as he could. He was letting her know with his body language and his expression that he was paying close attention and that she could ask him whatever she wanted. But he was trying not to be too passionate about it or excited even. He was trying to let her take the lead so she wouldn't get nervous, or embarrassed or think better of what she wanted to do, whatever it was. Kate opened her mouth and started to say something but she couldn't. She dropped her head and laughed. Advanced Primatology Ch. 08 "I can't say it. It's too embarrassing. You can't make me say it." "You don't have to say it," Chad drawled at her, sweetly, laughing a little too. He put his hands to her waist and held her. "You can just do it." He bent his face down and looked at her. He wasn't nervous at all, and he wasn't embarrassed at all. He was looking at her and holding her in a way that was making her feel less nervous too. Kate looked up at him and pressed her hands into his chest and backed him against the wall again. She stepped right up to him until her breasts were pressing against the backs of her hands and their crotches were almost touching. She could feel the heat rolling off his crotch in waves and she was pretty sure he could feel her heat too. She turned her head to the side and kind of nuzzled up into the side of his neck. She held her nose right up against his stubbly beard and took a long breath in, just drinking in the scent of him. That's all she'd wanted. Just to smell him like that. She exhaled slowly, sighing with pleasure, and brought her nose to the other side of him and drank him down again, losing herself in his scent. It was a mixture of lake water and sweat and maybe a little of his sperm too from last night with Karin and a heavy dose of testosterone for sure. It smelled heavenly. It was powerful and raw and it was making her feel lightheaded and a little out of it. She didn't even notice really, when he held her a little closer to him with his hands tight around her waist. And she didn't really notice when she just melted into him and started smelling his neck and shoulders and chest all over. He smelled perfect and he felt perfect. She had her hands around his waist now and her breasts were pressed right up against his chest and they felt like they were made to be that way. The muscles all along the side of his waist were so solid and massive but supple too and responsive to her touch and she'd never felt anything like them. She had her crotch pressed up against him and it felt like it was designed to fit together tight to his and to grind against him a little like she was doing right now, without even realizing. Kate took one more whiff of him and then she leaned back to get a better look at his face. Their crotches were pressed against each other and Kate could feel him stiffening a little in his damp speedo. She could feel herself sliding against him in her tiny suit bottom that was a little damp now too, but not from swimming. He was definitely getting hard now and she was definitely sliding against the base of him a little. Chad smiled at her, sweet but cocky too, and Kate liked it. He let his hands slide to her hips. Kate was looking up at him and her eyes were half closed and a little glassy even and she could feel his cock getting long and stiff between them. She could feel her lips swelling up in her tiny suit bottom and opening and moistening for him. There was nothing but a little wet spandex between them. Her hands were on his naked waist and her tits were resting against him in her bikini top. She knew they felt heavy and full against the top of his stomach and the bottom of his chest. He was just the right height. "Happy now?" Chad asked her. Kate shook her head. "You want something else?" Kate nodded. She flashed him a devilish smile as she took his hands in hers and guided his arms straight up over his head. She backed him tighter against the wall. She leaned and pressed her weight on him and brought her nose to his armpit and took a long breath in, sighing a little louder this time when she exhaled. "Don't get the wrong idea, okay? Don't let it go to your head," she told him as she brought her nose to his other armpit and breathed in smooth and deep. She closed her eyes and smiled. "I like you okay? I like working with you and I think you're smart and I'm attracted to you. And it's okay if we fool around a little as long as we keep it to ourselves so people don't get the wrong idea. Okay?" Chad nodded at her and played it cool and quiet. "You can still be with Karin and Jess and Elise and any of the other the other girls because I'm not going to do any of that stuff they do with you, okay? We can fool around with each other a little while we're working together during the day if it feels good and it helps us be a good team. But we're not going to sleep together, okay?" Chad nodded and held her tight to him and she melted into him again. "There's something else I'd like to do. Promise you won't laugh this time?" Chad nodded. "I want to feel your beard." He smiled at her, surprised a little, but he didn't laugh. Kate reached up, looking right at him with her big brown eyes, and started scratching and raking her nails all over his neck and the sides of his face and even through his hair. He held his hands tight on her sides and pulled her toward him and she relaxed right into him and drank in his scent. Her suit bottom was soaking wet now and their crotches felt a little more slippery and they were sliding against each other a little more. Kate put her hands to his chest and leaned back and looked at him again. Her crotch was making little circles against the base of his shaft. He was looking at her now in the way a guy looks at a girl when he knows he's going to have sex with her eventually, maybe not right now but soon for sure. He wasn't even bothering to pretend any more and neither was she. She had no idea what her rules were. She looked down and admired the way his big cock was filling out his speedo. She could make out the shape of his wide, mushroom head through the wet spandex. "You like it?" Kate looked up at him with a dreamy expression and nodded slowly. "Yeah, you like my beard?" Chad teased her. He knew she'd misunderstood him. Kate rolled her eyes and blushed. "I'm not sure if I like it. I need to try something else." She reached up and put her hands behind his neck and pulled him down to her and opened her mouth, warm and wet. She couldn't believe what a good kisser he was and how good it felt to be held tight against him like that while their tongues were playing together and they were breathing into each other's mouths. She couldn't believe how skillful he was with his tongue and his lips and with his hands around her waist. She loved the way he just dropped them to her cheeks like that and cupped them, almost sweetly, but pulling her toward him firm. It was obvious right away that he'd kissed a lot more people than she had, and she could feel right away that they were on his turf now. They were playing his game. There was not doubt that he was a more experienced and knowledgeable lover than she was and she knew that the further they went with each other the more they'd be in his domain. They were kissing each other full on the mouth and their tongues were wet and twisting together. Her other lips were wet too and they were sliding against him through the damp spandex and he was so hard. She had no idea where her boundaries were any more. Karin was just a little bit younger than her, and being a postdoc wasn't that different from being an untenured professor, and being engaged wasn't that much different than being in a marriage that had just been torn apart by your shithead husband and had to be rebuilt again brick by fucking brick. And Karin had fucked Chad god knows how many times last night, and god knows how many different ways, and she probably loved every second of it. She didn't know what her own rules were at the moment but she was pretty sure that what she was doing now with Chad was okay. Otherwise it wouldn't feel this good. Otherwise she'd stop herself. If she wanted to do it this badly then it was okay. As long as they kept it to the days when they were working together and it didn't bleed over into the nights and start complicating things. Chad had his stubble beard against her neck now and she still wasn't sure whether she wanted him to shave it for her later, but she was very glad he hadn't shaved it yet. It felt electric the way he was scratching her with his bristles while he kissed and licked and sucked her neck and even bit it a little. She was pretty sure that was fine. And she was just fine with it when he grabbed her little sport bra top by the bottom and pulled it up over her tits, fast and sure, and they just spilled out for him. And it was fine when he took them in his hands and weighed them and bounced them and squeezed them like they belonged to him now and he knew just how to treat them. And she knew it was right when she reached down and snaked her fingernails inside the waistband of his speedo and down inside and felt for him. She wasn't breaking any rules when she held his cock tight by the base like that. And not even when she stroked it a little and they held their mouths close to each other and looked at each other and groaned and sighed. She couldn't believe she had his real cock in her real hand, finally, and she couldn't believe how hot and fat and hard it was. She couldn't believe how thick it was and how much it weighed in her palm. And she couldn't believe how long it was as she started to stroke it up and down, making a loose circle with her forefinger and thumb and pulling the skin gently up his shaft, making sure she felt the whole length of it, from balls to bulb. There were no rules any more about what she could do to him with her hands, and there were no rules about his hands either. He took his right hand from her breast and slid it smooth and sure into her suit bottom and found her wet lips and spread them and painted her all over with her juices. He could massage her like that every morning and every day at the swimming hole as long as they kept it within bounds. As long as they said good night after the evening work was done and went to separate beds. "Don't let it go to your head okay? I like you and I think you're hot and I want to do things with you. But you have to keep your head." Chad was nodding and smiling. Kate was close already, just from the thrill of stepping over the line with him like that, finally doing it for real. He was making her so hot with his hand working her breasts and rolling her nipples and his finger stroking her clit and making it purr for him. His cock felt so hot and hard and heavy in her hand. She stroked it hard and started picking up the pace. She could tell she'd be cumming around his hand in no time and she wanted to badly. She wanted him to see her like that. She leaned into him and smelled the sweat and the lake water and maybe the sperm on his neck and her saliva now too. His scent was so masculine and raw and she was practically drunk from his fumes. Her stomach was tensed and the little muscles around her pubic bone and her anus were starting to quake and spasm. He had his mouth held tight to her, like she'd just had a heart attack or something and stopped breathing and he was trying to bring her back. He had his tongue in her throat and she was groaning out for him loud. "Ummmmmppph, O god, mmmmmppph." And then he stopped stroking her and held her breasts from the bottom and pushed them up to him with his big hand. He brought his mouth to her breasts and started kissing and sucking and licking her nipples, one after the other. He was tapping her clit, her fat red drum, with the middle finger of his right hand, keeping a steady beat and just tapping her and tapping her, just right, as her pelvis started vibrating and bucking and quaking. Her nipples were swollen and red in his mouth. She was holding his cock hard now with both hands like it was a handrail on a train or something and she was trying to stay on her feet as the ride got faster and wilder. She was hanging onto him for dear life with both hands and she couldn't see or hear anything and her clit and her nipples were so plump and juicy she was afraid they might burst. Chad's tongue and finger kept sliding over them and circling them and her pelvis kept humming. She was breathing in and holding it for an instant and then just letting it go, and every time she did the little waves of pleasure got a little bit warmer and a little bit brighter and she had to hold on to Chad's cock a little tighter to keep from falling over as her knees buckled and she moaned into his mouth. She started counting to herself and holding her eyes closed tight like she did sometimes when she wanted to prolong her pleasure. He had his middle finger and forefinger up her wet canal now and he was stroking her clitoris with the fat part of his thumb and she was squatting down a little on his hand and grinding her pubic bone against it and quaking harder and harder and she looked down and she could see her juices dripping down from his hand and she looked up and he was looking right at her. She leaned forward into his chest and opened her mouth and started licking him and smelling him while he thrust his hand up inside her and thumbed her fat button. She squatted down on him and rode his hand. And then her spasms got faster and more intense and he had to put his arm around her back to keep her from falling over. She was biting his chest now hard and his hand was all the way inside her and she'd counted all the way to five or maybe six and she hadn't stopped quaking. The next thing she knew Chad was holding her tight to him and she was drinking in the heavy scent off his chest and armpits and her whole body was glowing. She could hear Elise and Karin calling for them from outside the women's cottage, and wondering where they were, and worrying about the time. And she could hear footsteps coming toward them down the grassy slope. Chad's cock was in her hand and his hand was on her crotch and they had to think fast or someone would find them and get the wrong idea. She pulled away from him and pulled her top down and rearranged her suit bottom. "See you at the swimming hole later, okay tiger? And don't you dare shave that beard." She gave him a quick peck on the cheek and turned and hurried away. Part 3 Kate wanted to kick herself in the head when they finally found M group, a little further up the mountain than last time, and she realized that Brad and Mahalia were already gone. Of course they were! It was the perfect time to just slip away unnoticed! She should have seen it coming but she hadn't. It was the perfect time because the second most popular female in the group was at peak fertility and every male in the group was wild to mate with her. Mahalia knew that she had to sneak off with Brad now, before her own sex skin started swelling, and her odor changed, and the males turned their attention to her and started herding her and maybe beating her to keep her close to them, to keep her in their domain. So she just slipped off with Brad while the other males were busy challenging each other and mounting the other mature female. Kate was cursing herself out loud because she should have seen it coming. Mahalia had fooled everyone, including her. "Fuck me! I can't believe I was so fucking stupid!" She said it so loud that a couple of the female chimps looked at her, eyeing her curiously. "Let's go. We have to find them." She stood up and put her pack on her shoulders and waited for the other three (Chad, Karin and Kevin) to follow her up the mountain. She needed to stay in contact with Brad and Mahalia the whole time they were on safari together, mating exclusively, so she could observe them closely and take careful notes. Otherwise she wouldn't be able to publish her research and her new theories wouldn't be worth shit to anyone. No one would care that Mahalia had chosen Brad because he was sweet and attentive to her, body and mind, and she wanted to have a baby with exactly those traits, with that personality. And no one would care that females like Mahalia were playing the long game. That maybe over millions of years, or tens of millions of years, more and more mature female chimps would make the same choice as her, and evolution would work its magic, and chimp society would transform for the better. And maybe generations and generations from now the descendants of Mahalia would be the empresses of the forest. She knew it was true but no one would give a crap unless she could prove it by watching her with Brad first hand. "Let's go!" No one was moving and she was feeling more and more pissed off. "We can't," Chad snapped back at her. "M group's territory goes all the way down to the lake. So Brad and Mahalia have probably gone deeper into the mountains to hide. It will take a while to find them. And even if we do, we'll be too far away from camp to get back before night. We don't have tents or food or enough water or anything. We need to go back to camp and gear up and make a plan. We should fire the emergency flare so the other groups will come back to camp too. Then we can set out in the morning and we'll be prepared." Kate knew he was right, and so did Karin. They looked at each other and nodded. Everyone stood up and put their packs on their shoulders and turned and started marching as fast as they could straight down the mountain. When they got far enough away from the chimps that they wouldn't scare them Chad took the emergency flare out of his backpack and lit it and fired it straight up. That was the sign that something big had happened and everyone needed to get back to camp as fast as they could. Part 4 Kate's mouth was dry and her heart was racing as soon as they got to camp and she saw him, but not from pleasure and excitement. It was more disbelief and rage. She couldn't believe the nerve of him to actually come here! Brian was standing there in his pressed white shirt and his pressed khakis like he'd just hopped off a luxury jet from Rome or Paris or whatever beautiful city he was being famous in, and getting praised for his brilliant discoveries. Maybe he was even getting his cock sucked too. She didn't know anything for sure about her husband any more. The picture of Elise on her knees in front of him with his dick in her hand had been bad enough. But strange as it seemed what she found out about Karin had been even worse. She really couldn't believe that Brian had threatened her like that when Karin caught him with Elise in his office. She really couldn't believe he'd threatened her career and used his power and authority over her to intimidate her and silence her. She'd always loved him in part because he'd always been one of the good guys, one of the new kind of male scientist who didn't act that way to young women with brains and determination and big dreams. He'd always been the kind of guy who didn't do that kind of thing because they knew it was unfair, and it felt wrong, and it was bad for science too if women didn't have a fair chance to get their voices heard. She was angry and hurt about Elise but at least she understood it. But she couldn't understand the way he'd treated Karin, and she didn't know if she could forgive him for it. She threw down her pack and walked right up to him and grabbed him roughly by the arm and yanked him and pulled him right up the slope to the women's cottage. "What the fuck are you doing here? What the fuck are you doing here when I told you to stay away or I was going to fucking leave you? What part of that didn't you understand?" Brian was looking at her scared and sheepish but she could tell he was glad to see her all the same. It was really pissing her off. He was so sure of himself underneath it all! "I'm sorry Kate. I couldn't stay away. I had to talk to you. I'll only be here overnight and then I'm flying back out to Geneva. I had to talk to you and try to explain." "I don't give a fuck what you had to do, okay? I don't give a fuck about that. This is not the right time, okay. This is like the worst fucking time in the history of the planet and you should not fucking be here because I told you not to come." Advanced Primatology Ch. 08 "What's wrong? What it is it?" He knew it was about work, and he knew he could help, and he knew that Kate would want his help. Kate was feeling pissed off at herself and at the world because she did want his help and there was nothing she could do about it. It had always been one of the best parts of their marriage, something that really worked. The way they understood intuitively when one of them was on the verge of something big with their research, and how they always pulled together as a team at times like that. Brian was very smart, and very experienced, and he paid attention to her when she was onto something big, and he always helped. She couldn't stop herself and she hated herself for it. "I've been watching this mature high-status female (Mahalia) with a clever young male (Brad) and they've been doing amazing things. I've been watching them and waiting for them to go on safari together but they caught me off guard. The disappeared from M Group last night and I've got to find them fast because I'm really onto something and I need to watch them alone together." Brian nodded seriously and walked over to the coffee table and started looking through the different maps. He picked one up and took his forearm and swept everything else from the table. He was always so focused and decisive like that and it was one of the things that Kate loved about him most. He spread the map out flat on the table and studied it carefully. "Here, here, and here." He was jabbing his finger at the map in three places, and nodding at her, and trying to reassure her. "I know M group. I've studied them many times. Brad and Mahalia will be in one of three places. I'd bet my life on it. They'll be in one of these three high valleys just on the other side of the mountain." Kate was standing next to him close and bending over the table and studying the map along with him. She was nodding and smiling. "That makes sense," she exclaimed. "Those are the perfect places because they're outside of M group's terrain and they're up high so it's hard work to track them there." "Exactly," Brian nodded. "And they'll have lots of streams and water holes for drinking from and cooling off in, and lots of fruit trees, and lots of dark shady nooks for copulating and grooming and long naps. It's like paradise over there. It's like a honeymoon resort for chimps." Kate was nodding and picturing it. She stood up and faced Brian and looked at him seriously. "What would you do if you were me? How would you play it?" Brian didn't miss a beat. "I'd split into three search parties and I'd send one group to each valley. You're sure to find them that way. I'd make the search parties small and light. Maybe even split into pairs. You want to be able to travel fast so you should only take the students who are in the best shape. And you should only take students who know how to use their heads. You have to be smart about it, and quiet, because Brad and Mahalia will be listening closely for any one sneaking up on them and finding them. I'd pair Jess, Karin, and you with one student each and give you enough food and water and a tent and camera batteries so you could stay in the mountains for maybe four or five days if you had to. I'd leave the other kids down here and tell them to search the lower slopes in case Brad and Mahalia are hiding near the lodge. That happens sometimes." "I can't do that," Kate shook her head and cursed. "It's against university rules to leave the students without a faculty member, and I'd get in serious trouble if anything bad happened. They'd fire my untenured ass." Brian nodded. He knew it was true. Kate got an idea. "What if you stayed? What if you stayed with the kids here and looked after them? I'd ask you to lead one of the search parties, honestly, as much as I want to fucking murder you at the moment. Because I want to find Brad and Mahalia more than I want to murder you, and you're a very good tracker. But I can't do that to Jess. I can't ask her to stay behind. She's worked too hard and she deserves to be in the field. Can you stay?" Brian was eyeing her uncertainly. He knew this was a golden opportunity for him to win her back by helping her out. And he didn't want to set her off by having to say no. "For a few days, yeah, but not for four or five days. I'm sorry Kate. I have a big talk in Geneva okay? It's the biggest talk of my career Kate! They're giving me a big award and I can't not be there." "A few days will be fine, thanks." She felt pissed at him for putting himself first even now, but she wouldn't have expected anything different, and part of her even understood. And she had more important things to worry about than her hurt feelings right now. Everything was on the line for her. "Which valley should I pick?" Kate asked him. "Which valley gives me the best chance of being the one to find them." Brian pointed to the central valley. She nodded at him and smiled. A few days would be helpful. She was grateful to him even. It would lower the chances of something bad happening with the kids that she'd be blamed for and fired over. She looked out the front window and saw Jess and Karin and all the other kids throwing their packs down on the lawn and looking very serious, scared almost. They didn't know what was happening yet. She stood up and walked right over to them. She paused in the doorway and turned back to Brian and gave him a withering look. "Thanks for helping, okay? But try not to fuck too many of the students while you're here. Try to do that much for me." Part 5 It was late. Kate and Jess and Karin were sitting on the floor in the common room with their notes and maps spread all over the coffee table. They'd finally finished organizing the gear for the search parties and packing it six ways and going over their routes for the next day. They had to finalize a few details and then they needed to go straight to bed and sleep and wake up bright and early for a good start. Brian was sleeping in Kate's room. He'd tried to stay up but he was jet-lagged and none of the women wanted him around for the final planning meeting anyway. Kate had thought about sending Brian over to the boy's bunkhouse but then she realized it would be too humiliating for both of them. She wondered if Karin had made plans for Chad to sneak over to her room later. They'd have to be quiet now that Brian was here. He played tennis with Karin's husband sometimes, and as a tenured professor in her department he was technically her boss. "Well," said Jess, yawning, "I guess that about does it. I guess we just have to figure out which students to take and then we can get to bed. Let's do it. I'm wiped out. Who do you want Kate?" Kate eyed Jess and Karin apprehensively. She knew what the right answer was and she knew how it would seem. She knew they'd understand on some level that Chad was the logical choice because he was in the best shape, and he was the smartest and hardest working student, and because he and Kate got along really well. They worked very well together and he would help her the most. He would give her the best chance of success. But she also knew that they'd be wondering about the long nights together in the lush forest with the insects chanting all around them while they slept side by side in a little pup tent and waited for the first light to show so they could get moving again. They'd definitely be wondering about that. But she couldn't worry about it now. It was the right choice and they didn't have much time. "Chad," Kate declared flatly, looking right at both of them and almost daring them to have any reaction at all other than nodding their heads like it made perfect sense and they were fine with it. That's just what they did. Kate barely even heard them when they both said which student they wanted to work with. Maybe Karin picked Courtney and Jess picked Kevin. She couldn't be sure. Maybe it was the other way around. Kate was thinking hard. She was kind of amazed and wonder-struck at how easy it had been for her to make her choice and to declare it straight out like that. It felt so good and right that in some ways it didn't feel like a choice at all. It felt like what she had to do to get what she wanted, plain and simple, to get where she wanted to be in life. Chad was the best man for the job and there was no doubt about it. Part 5 Karin was on top of Chad in her bed leaning back on his knees and riding him hard. She was going to have to be careful with this kid. He was very beautiful, and smart and sweet too, and he knew how to please a woman no doubt about it. He knew how to make a woman cross her boundaries, and draw new ones, and cross those boundaries too until she didn't have any left. She'd already caught herself thinking about it for just a second too long when he asked her if she really needed to wear her diaphragm tonight, their last night together, almost pleading with her. He wanted to feel her naked so badly. And she wanted it too. She'd just caught herself wondering if it would be so terrible, really, to stop riding him for a minute, and take her diaphragm out, and let him slide back inside her. He was so long and his tip was so fat and fleshy and she loved the way it felt when she squatted down on him all the way and he bottomed out inside her, his broad head putting pressure on the plastic disk that was the only thing between him and her cervix. She really wished it wasn't there. He was looking up at her and kind of pouting at her and she felt like he was reading her mind. "I know baby. I know you want to fuck me raw, and I do too, but we can't. It's a bad time for me and I think the fiancé would be upset." She was on her knees leaning forward over Chad and her tits were bouncing up and down hard for him. He sat up toward her and took them in his mouth and kissed them and sucked them loud and wet. She felt little jolts of energy course all through the delicate nerves that connected her nipples to her pussy and she got wetter and warmer for him as he thrust into her from below, meeting her hard downward thrusts with his smooth upward ones. She'd never been filled up like that before and she loved it. It was driving her out of her mind. She was raising off him slow just a little, watching the base of his cock slide out of her all slippery and shiny, and then just plunging back down on him so he could stretch her out and fill her up and press the diaphragm against her cervix with his fleshy bulb. He was squeezing her tits with his hands and shaking them and sucking on them hard and biting her nipples. They were red and juicy and a little bruised around the areolas, her dark round wide circles that men loved so much because they looked so sexy and womanly on her full chest. It felt hot and dangerous to have him just eat her up like that with his mouth while he filled her warm pussy with his big hard cock. "You've got a thing about that don't you? You've got a real thing about fucking girls bareback, don't you stud?" Chad nodded at her and smiled. "And you've got a real thing about cumming inside girls too, huh? You like that, don't you? You like filling up their pussies." He was nodding and breathing hard and kind of pouting at her. "I like it too. Oooohhhh. It feels nicer that way. Ugggghhh. But you've got to be careful stud. One of these days a girl is going to use that against you and get pregnant by you on purpose. Oohh my god. Especially when you're playing pro soccer and making all that sweet cash. Ooohh fuck. You're going to have girls lining up to let you put a baby inside them. Oohhhh fuck me." She was leaning forward all the way now and her full breasts and big nipples were resting lightly on his chest and brushing over him as she fucked him hard and fast and her ass shook for him as she pounded it down on his shaft, all the way to his balls. "I don't think I'm going to play MLS, though," he answered her, groaning and gasping and out of breath a little. "I think I'm going to go to grad school and be a primatologist like you." Karin smiled at him at first, flattered. Then she made a sad face. "Too bad for me. Uummmph. I was hoping you'd get a big contract with L.A. Galaxy or something. Uggggh god. I was hoping I could come visit you in your hotel whenever you were in Atlanta or D.C. Ohhhhh fuck. I was hoping you'd be a big hot rich soccer star and I could be your groupie whenever you wanted. Ooohhh fuck me hard baby." "O yeah?" "Yeah. It would feel so dirty sneaking into your hotel like that. Ooooooooooohhhh jesus. And waiting for you in bed until you came back from the game and fucked me all night long. " "Yeah, you'd do that for me? You'd sneak out on your husband and come fuck me in my hotel room like the all the other groupies?" Karin rolled her big brown eyes at him. She knew what he wanted and there was no harm in it. "Anytime you wanted, stud. Anytime you called." "Yeah? How come? How come you'd do that for me?" Karin leaned back with her hands on his knees again and started fucking him longer and deeper, pulling all the way back until she could see his whole shaft fat and glistening between her thighs, and his blue bulb between her lips, and then bringing her crotch forward and taking him back inside her all the way, grinding her pubic bone against his when she got to the base of him. "Because I love your big cock, that's why. Oohhhh Christ. I love what you do to me with your fat cock." "Oh yeah, darling?" he drawled. "And would you have to wear a diaphragm when I fucked you with my big fat cock. If you were my groupie and I was a rich soccer star? Or would you be one of those girls that wanted to have my baby?" "No, sweetie, I'd be married. Uummmpph. I'd belong to someone else. Ugggh god. But you could borrow me when you were all bored and lonely in your hotel after away games." They were fucking like monkeys now and getting off on the fantasy of Karin being Chad's road slut and slipping out on her husband to fuck him in his plush hotel suite. Karin was leaning all the way back and pulling all the way up off him and then just dropping herself down to his base and taking all of him inside her. And he was thrusting upward with his hips and stuffing her with his shaft. "MMMmmmppph. Oh my god baby. That feels so good when you fill me up like that." They fucked like that for five minutes or so until they were both heading for the edge of the waterfall. Chad sat up and arranged Karin in his lap facing him and fucked her deep and slow while they looked at each other and held their mouths open and slithered their tongues together. "What if we'd met when we were both in college," he asked her sweetly, whispering in her ear. "What would have happened then?" Karin smiled at him and started circling her hips and pressing her tits together with her arms so they looked cuter and fuller for him. He bent his head down and suckled her. "I don't know baby. I don't know. But we definitely would have hooked up. And we probably would have started dating if I had anything to say about it." "Yeah?" "Yeah, baby. Once I got a taste of that cock I'd want it all for myself." "O yeah? And do you think you could get it?" Karin flashed him a devilish smile and pulled her crotch away from him until she was holding his purple bulb between her wet lips. She started circling her pelvis and slathering him with her juices. "I think so baby. I have my ways. I'd probably go on the pill for you and let you fuck me bareback and cum inside me just like you love it." "O yeah? Do you think it would get that serious?" Karin was nodding and gasping and riding him fast and smooth. "And do you think we'd have ended up getting married even? Do you think it would have gone that far?" Karin was nodding and groaning. "Maybe we would. I don't know. I like you okay?" Chad was nodding and groaning and thrusting up into her from below and his balls were contracting. "I like you a lot and maybe I would have married you. MMmmmpph. And maybe we would have tried for a baby. Oooohhhh Christ. And you could have fucked me hard and raw every night until the job was done. Ugggh god. Until I was pregnant with your baby. Oohhhhh fuck me. Until you knocked me up with a beautiful baby with your beautiful cock." Chad had his eyes closed and he was picturing fucking her bareback like she was his wife and she wanted him to knock her up good and hard. She could tell he was really excited and she could tell he wouldn't last much longer. His cock was bigger and plumper than she'd ever felt it before and she wouldn't have believed the feeling of it inside her if someone had described it to her. She wanted to let him stay inside her and just let go and explode. But she knew she couldn't, and she knew if she let him stay inside much longer she wouldn't be able to stop herself. She didn't need to cum again. She was feeling so satisfied already. And she didn't want to take any more risks with Chad. She pulled off him and her pussy made a little sucking sound, almost gasping, as Chad's fat tool popped out of her. She got on her knees between his legs and took him in her hand and stroked him long and slow while she looked up at him with her deep brown eyes. She opened her mouth wide and brought her lips down to the head of his cock and just sucked him down, holding him tight in her mouth and using her tongue to caress his glans and her lips to milk his hard long shaft. He couldn't cum in her pussy, even with the diaphragm, but she wanted to do something special for him anyway. She was going to let him cum in her mouth, and right down her throat if he wanted to, and she was going to swallow every drop of him. She was going to drink him right down, hot and creamy, and then she was going to clean him off slow and wet with her tongue from his fleshy bulb, to his thick shaft, to his full round balls. And if he was still hard when she was done, and he wanted to cum in her mouth again, she was going to blow him for as long as it took to get the job done and thank him properly for everything he'd done for her, for an hour if she needed to. He was a very beautiful boy and she needed to be careful. This would have to be their last night together. Part 5 Kate couldn't believe she was riding her husband like this, reverse cowgirl with her ass in his face, and she couldn't believe she was about to cum on his shaft. How the fuck had this happened? She hated herself and she hated him and she wanted to cum so badly. She'd woken up in the middle of the night with Brian spooning her in the tiny bed and she'd never felt hornier in her life from her morning make-out session with Chad and from the excitement she felt about working with him more closely over the next few days and fooling around with him a little more. She'd had every intention of sticking to her rule about keeping their relationship a daytime thing, a work thing, and not letting it cross over into sharing a bed at night. But things had changed today. It was out of her hands now. The gods had intervened. She had no idea where her boundaries were with Chad but she knew they'd be touching and kissing and licking each other all over in the little tent they'd be sharing for the next three or four nights. They were going to wake up tomorrow morning and do a quick stretch together and put their packs on their shoulders and hike all day if they had to until they were deep in the mountains and maybe they found Brad and Mahalia. And if they did find them they'd stick close to them and follow them the whole time they were on safari together. They would work together all day, and eat dinner together and talk, and then sleep together in the little two-person tent. There was no chance they wouldn't be getting each other off with their hands and mouths every night and probably every morning too. It would be better if they just did it first thing, as soon as they finished dinner, so they'd get a good night's sleep without all that sexual tension hanging in the air. Advanced Primatology Ch. 09 Part 1 Kate couldn't sleep. She felt awful about herself and about everything that had happened yesterday. She felt awful about fooling around with Chad and letting him make her cum with his hand like that while she was smelling him in the thatched cabana after yoga, and about the way she'd let Mahalia trick her by going on safari with the clever young male chimp a little sooner than she'd expected, and even about the way she'd used her husband and his body for distraction and selfish pleasure and maybe even revenge last night, turning around on top of him and shoving her ass in his face and slamming it down on him hard even though she could tell she was hurting him. She'd even bent his cock backward a little at one point because it gave her a better angle. She shook her head remembering beating him on the back of his head when she was finished and wanted him to get off her right away. She could always rationalize what she was doing in some messed up way. That was one of her gifts, really, and one of her biggest flaws too. She could always use her reason like that to explain herself, no matter how impulsively she was acting. But there was no point denying it. She'd been insane the whole day. She thought about taking a sleeping pill but decided against it. She needed to think things through. She needed to sort out all the vague, ungovernable feelings that had been swirling around inside her ever since the trip started. She needed to figure out who she was angry at, and who she loved, and who she hated and why. A few weeks ago she'd been ready to mate with Brian in the true sense of the word, to join her body to his as intimately as possible for two people and make a baby with him. But now she didn't really know what she wanted. Or she did know what she wanted, but she couldn't quite believe it yet. She was pretty sure she didn't want to mate with Brian anymore, at least not anytime soon. And she was very sure she wanted to have sex with Chad, probably more than a few times, while she was alone with him for three or four nights in the cloud forest high in the mountains. She needed to figure out why, and what she was going to do about it. And to make things worse she needed to figure out pretty much the same things about the chimps too, especially about Brad and Mahalia, or her whole career would go up in smoke. She needed to figure out what made them tick when they partnered off like that, despite the age and status difference between them, or maybe because of it, and slipped away into the forest together. That was why she'd become a primatologist. That was the attraction and the mystery. In her entire life Kate had never met a single primate—the human ones included—who wasn't ruled by their desires in some way, by their partner's if not by their own. Even her typical, suburban, affluent parents in Pasadena back in the nineties, right at the beginning of the tech boom, with their long sexless marriage, and her father's business trips practically every week, and the fights and tears and seething bitterness from her mother whenever he came back from certain places. She'd known about their unspoken arrangement at some level the whole time she was growing up but she'd only figured it out consciously when she was in her late twenties, and suffering from extreme writer's block, and finally got herself on the couch for some serious therapy. She'd finally figured out that her handsome, successful, charming daddy was the kind of man who needed to be pleased by many women, in many different places, and that he was allowed to live that way as long as he loved his wife and daughter in the way that mattered the most to her mom. As long as he gave them the best house and clothes and schools that money could buy, and went to the really important parties and galas with her mom and was his charming, attractive self, and as long as he was careful and discrete so that his daughter would never know the truth. That was the deal. And that was why the atmosphere in her house had always been so tense and charged that it made Kate feel nauseous and jittery every time she walked in, but especially when she came home from college. And that was why she'd always been so fascinated with chimps, who were ruled by their desires and fears in just the same way as her parents, but with so much more honesty and directness in their own primate way. And that was why she had fallen head over heels for Brian as soon as she met him, and clung to him like a barnacle to the side of a big rock or a whale or something. She was sitting cross-legged at the lake looking out over the wide dark water toward a horizon full of radiant stars. She'd been tossing and turning in bed and she was afraid Brian would wake up (she didn't want to talk with him yet) so she walked down to the shore almost without realizing it. The air was crystal clear and the moon was directly over her head—a blazing crescent, sharp and white. She could smell the mountains and the forest behind her. She was thinking about the millions of strange fishes swimming beneath the surface of the water, in the shallows close to her, and in the dark, almost unfathomable depths at the center of the lake, right where it met the sky. It was one of the oldest lakes in the world and one of the deepest too, formed tens of millions of years ago, and the fish that lived there, the cichlids, were some of the strangest creatures on the planet. They were bright and intricately patterned, more like ocean fish on some tropical reef, and there were hundreds of different species of them living together in a single lake, and each of them had evolved unique behaviors for feeding and reproducing and protecting their young. They didn't live in any other lake on the whole planet. Life was so various like that. It could take so many forms. She was thinking about how in the forest behind her lived a species of primate who shared 98% of her genes, and who were her closest living relatives on earth, but who remained complete puzzles to her, even though she'd studied them seriously since she was a girl. And she was thinking about how every one of the billions of bright or faint stars in the vast sweep of sky above her head could be another world, a sun at the center of a distant solar system, with a hunk of lava, and rock and gas orbiting it at just the right distance so that life could take hold there too, and other creatures could evolve, infinitely strange. Kate sat there thinking about all of these things until her brain felt like a tight knot. It was like her brain was a big knot someone had tied inside her skull, and the ends of the rope were coming out her ears, and God or the universe or whatever was pulling the ends of the rope tighter and tighter until she had a searing pain in her forehead and a vague sense of anxiety and terror in the pit of her stomach. She sat there feeling like that for maybe three or four hours, maybe longer, and then all of a sudden the knot pulled a little bit tighter, and then somehow, almost magically, it slipped right open. She felt calm and free. The sun was rising and the clouds at the far horizon were glowing red, like warm coals. Kate knew what she had to do. She stood up and walked straight over to the mess hall and made a big pot of coffee. She grabbed the pot and two mugs and walked to her tiny bedroom in the women's cottage. She sat on the edge of her bed and watched Brian sleeping on his side. He looked so beautiful and fragile in that position, like a young boy, with his head cradled in his own arm and his knees pulled up toward him a little. He was older now than when she'd met him but he was still very beautiful, maybe more so even. He was still strong and masculine looking, so powerful in the chest and shoulders. But he was covered all over with soft gray hairs, and his face and limbs were softer and more voluptuous too. He reminded her of certain older alpha chimps who grow beautiful in just that manner. She loved him so much it made her chest ache when she looked at him like that—like a beautiful primate. He was so natural and pure in his own way. He was also just like her father. She knew that for a dead certainty now, and she'd felt it in the back of her mind for years, like a vague, nameless dread. He was the kind of man who would always need to be pleasured by many women, not just one. She didn't hate him for it and she didn't even blame him. But she was pretty sure that she couldn't be his wife, and she was almost positive that she couldn't have his children. She'd have to become too much like her mother to do that. It would mean killing off the best parts of her. She didn't know what she was going to say to him, but she knew that whatever she said would be the whole truth. She'd try her best not to hurt him. She reached over and shook him by the shoulder, looking down at him with sadness and real affection as he opened his eyes, and stirred himself awake, and tried to remember where he was and what was happening in his life. Part 2 Brian was in a daze. It had all been so quick and clean and unexpected, like getting your head chopped off by a guillotine. At first it felt awful. He'd wanted to throw up. She woke him up and let him drink a little coffee while she asked him how his head felt and apologized for being so insane the night before. Then she took a deep breath and started talking and the more she said the more he felt like he'd been kicked in the stomach and was about to vomit. She told him that she'd picked Chad as her partner for the mission to find Brad and Mahalia, and that some stuff had already happened between them, and that she couldn't make any promises about what might happen when they were alone together in the mountains. She could see how badly she was hurting him and she was sorry but she needed to be honest. They had to tell each other the truth. She hadn't meant to do things with Chad, but she'd felt hurt and angry and confused, and things had happened, and now she had feelings for him. She told him that she knew that Elise had not been his first affair, not by a long shot, and that neither of them believed she would be the last. Neither of them believed it because it simply wasn't in Brian's nature. That was the way he had to behave, and the way that he was going to behave, because that was simply his nature. He was the kind of older, high status male with strong physical desires that overpowered his will, and with a lust for life in all its magnificent variety, and with the brains and physical appeal and charm to get pretty much whatever he wanted from whoever he wanted. He was the kind of male who would always need a variety of females to satisfy him, on a rotating basis. She didn't hate him for it, or blame him for it, or anything like that. They were both primatologists for crying out loud! Neither of them believed for a second that there was anything particularly natural or necessary or even morally right about the ideal of lifelong monogamy between a man and a woman or any of that crap! Both of them knew that there were hundreds of ways for primates to live and mate and form groups together that were good and right for them! Life was so various like that. She didn't blame him. But she couldn't be his wife under those conditions either, because it wasn't in her nature. She needed to give herself to one man, body and soul, and she needed him to do the same. And she didn't think Brian could change. She didn't think he could be that man. She knew it was terrifying and she could see how much she was hurting him but she had to be honest. It couldn't be a lie. She would always love him and support him if he would promise to be honest with her right now. She wanted to ask him two questions because it would be better if she knew the answers. Brian nodded. It was like he was in a trance or something. The first question was whether Elise was the only student he'd had sex with since their marriage. The second was whether he really believed she would be the last. Brian was kind of watching himself from the other side of the room in amazement as he looked at Kate and shook his head slowly to the first question, almost without meaning to, and then kept on shaking it. It felt terrifying but in a messed up way it was a relief at the same time. He was short of breath and his heart was racing but he was relieved all the same. She was the person who knew him best and who loved him the most and now she knew the truth. She wasn't blaming him or screaming at him or even judging him or anything. Part 3 Chad was headed for the mess hall when he saw Elise and Sanjana and Pamela walking toward him in their short running shorts and their tiny bikini tops in different bright colors and patterns. They were all looking right at him and striding toward him in the way that would display their breasts and stomachs and hips for him to their best advantage, showing him how swollen and full and shapely they all they were in their own beautiful ways. Chad was thanking God or evolution or whatever it was that had made the world this way, with so many infinite varieties of the female form. He was looking at Sanjana's breasts, and thinking how much he wanted to oil them up with his big hands and squeeze and rub them all over, but especially her big nipples with the wide dark areolas (like Karin's) that were so womanly and fertile looking. And he was looking at Pamela's chest and picturing her flat on her back with his cock driving deep up inside her while her long nipples stood up on her tiny tits like two obscene red flower stamen or something, practically calling out to him to keep doing what he was doing because she was a beautiful flower, full of sweet nectar, and she was ready for him to drink her up. Elise saw him looking and she turned aside and walked over to him until she was right in his heat. She looked up at him with her pale blue mischievous eyes and her little upturned nose. "Have a good time with Professor Morgan, okay stud. She's counting on you. Do a good job for her keeping her safe during those long dark scary nights in the big bad mountains." Chad smirked at her and she smirked back. It was too bad he didn't get a chance to fool around with her a little more before he switched over to Ellen, and Jess, and Karin, and now even Professor Morgan. That was the problem with variety. Elise was a very interesting female and she made his cock very hard. She did funny things to his brain the way she teased him and got under his skin like that with her innuendo and her chest and ass and her whole way of carrying herself. "I'm so glad we'll have big strong Professor Phare to check in on us at the girls' bunkhouse. We'll be so bored and lonely now that Kevin's gone." She pushed her breasts together with her arms and pouted for him, bending forward a little. "O well. I guess we'll find some way to amuse ourselves. Maybe we'll play some tricks on Brian when he checks in on us during those long dark nights. Maybe we'll have a little fun with him. I know he likes me, and I told the other girls all about his big professor cock and how good it feels when he fucks you with it. Ask Kate about it, stud, she'll tell you everything you need to know about what's going on here." Part 4 Brian was walking across camp to find Roger. He'd just said goodbye to Kate and kissed her on the cheek and watched her put her pack on her shoulders and turn and follow that kid Chad Berwick up the green slope toward the mountains. It was all so fucked up, he thought to himself, and yet in a fucked up way it also made perfect sense. Chad was the strongest and the smartest and the most determined of the students and he would give her the best chance of success. They were attractive qualities in a mate. That's what Kate was going to do with him in the mountains, when you really thought about it. She was going to mate with him. She was going to join her body to his, and give herself to him completely, whether she knew it or not, because that was her nature: to give herself like that to one male at a time, for as long as it made sense. She was going to the cloud forest to mate with Chad in exactly the same sense that Mahalia was going to the same place to mate with her young male. Not that Kate would get pregnant and have a baby with Chad. Not that. Probably. Not on purpose anyway. But she was going to mate with Chad all the same, to bond with him as closely and deeply as two primates could. Once she'd set things in motion by starting a physical relationship with him, once she'd done that, there was no other way for the story to end for a woman like Kate living and working in close quarters alone with a guy like Chad. He wondered when her last period was, and whether it was a bad time for her, and what kind of birth control she had, if any. He wondered if she was ovulating and that had been a factor in her "choice." It was all so fucked up and yet it made perfect sense. He couldn't sort it out. Part of him felt like he'd just gotten his head chopped off and part of him liked it. Kate knew him better than anyone, better than himself maybe. There was no denying she was right. He was the kind of man who would always need a variety of women to please him, a harem with one of every kind of female he liked best. He was going to try to find his old friend Roger and see if he had a bottle of scotch or rum or anything strong, and if he could talk him into taking the little fishing boat out to the center of the lake and getting well and truly loaded. He looked up and saw Elise walking toward him with two other girls he maybe recognized from one of his classes last year. They were walking shoulder to shoulder in a line and each of them was wearing a pair of tiny running shorts and a tiny bikini top in a different bright color and pattern. The skinny Asian girl was wearing a green top with stripes and he could see her long nipples sticking out at him on her tiny chest. And the curvy Indian girl was wearing a white top with pink flowers and her full breasts were hanging out of it a little and bouncing nicely. And Elise's top was pale blue with little white polka dots and her tits looked fuller and rounder maybe than the last time he'd seen her, but they were still sticking straight up to the sky, and her pert nose was too. The three of them were like varieties of cichlids, each specially designed to be a different shape and size and color to delight his eyes. Elise walked over to Brian, right up close to him, and looked up at him with that half mischievous half innocent expression that did such funny things to his brain. "Professor Phare! I'm so happy to see you!" She reached up and put her hands around his neck and stood on tiptoes so she could give him a big kiss on the cheek. "I'm so happy you'll be looking after us while all the other grown ups are in the mountains. It gets so frightening sometimes just the three of us alone in the girls' bunk house at night." She turned and looked at her two friends over her shoulder. They smiled and laughed, arching their eyebrows at each other. "We get so bored and restless. Sometimes we have to bring Kevin over to entertain us. We would ask Chad to protect us and keep us company at night, he's so much bigger and stronger, not to mention hotter." She turned and shot a look to her friends again and they all busted out laughing. "But, well, you know, Chad's busy taking care of business at the women's cottage most nights." She shot him a wicked look, arching her eyebrows and flashing her eyes and making a little dreamy face like a woman who'd just been truly satisfied. Then she put her finger to her chin and made her eyes real big and played the innocent again, like she'd just thought of something really interesting. "That's probably why Professor Morgan chose him as her field work partner! He's such a hard worker! He can work hard all night and be ready to work hard again first thing in the morning! Well, bye!" Advanced Primatology Ch. 09 She turned and walked away, swinging her hips and ass for him, and so did Pamela and Sanjana. He remembered their names now. They were two of the sexy but nerdy ones from fall semester, the kind he liked best, and he'd definitely checked out their instagram profiles a couple of times, and he'd definitely enjoyed it. Sanjana had a big, round ass with a little cellulite around the edges. She was maybe twenty, and she was firm and high with just the right amount of jiggle. He was picturing bending her over and ripping down those shorts and fingering her from behind until she was a ragdoll in his arms, and the oxytocin was flooding her brain, and she was feeling safe with him and trusting and she wanted to be taught so many things by him. And he was watching Pamela's skinny ass and picturing how dirty and wrong it would look if she was on all fours in front of him, or if she had her ass held high in the air for him with her face in the pillow while she told him that he was teaching her so much and that she would be a good girl for him if he promised to keep giving her lessons. And Elise, well, she obviously had the best ass of all, and she was a nasty girl, the way she teased him like that and tried to get under his skin when he was trying to be a good man and a good professor to all of them. She was a very bad girl, the way she taunted him and teased him like that. She was a very misbehaved and dangerous girl and he needed to have a serious talk with her about respect and boundaries. Part 5 Every time Chad stopped and turned and looked behind him his heart skipped a beat. Kate was striding up the forest path in her usual work costume of blue Tar Heels baseball hat, sheer white long-sleeve shirt, and dark yoga pants. A couple of times she'd looked up and caught him staring at her in a funny way, marveling at how she could make even her "field work" outfit look so sexy and womanly and smoldering. She smiled up at him and arched her eyebrows in a way that was hard to read and they both ended up laughing and blushing a little. Chad was wondering about her husband Brian, and what was going on between them, and whether he could ask her about it. He was dying of curiosity. Part of him was fascinated by what Elise had told him, and part of him was disappointed, and part of him was excited because in his head it gave him a clear path to Kate, and maybe in her head too. Not that he would have let her marriage or his loyalty to Professor Phare stop him from doing what he wanted to do with her body. He'd been inspired by her husband's class and all, and he really did think he was an awesome guy, but the desire he felt for Kate went way beyond any of that. Professor Phare would be the first to understand, judging by what Elise had told him, which he was sure was true. Chad was dying of curiosity and he was breathing hard from the long climb up the mountain and starting to feel a little light-headed now that they'd gained some altitude, and he was looking down at Kate and she was breathing hard and looking right back at him with an expression of deep satisfaction, and even joy on her face. He was staring at her and remembering how gorgeous she looked when she was cumming hard around his big hand in the cabana yesterday morning, and how amazing it felt when he had her full breasts in his hands and his mouth. He was picturing the countless ways that he could take off her shirt and her pants and her hat and everything else at the end of the workday, and the countless things that he could do to her body once he had, all of them perfect. She was so beautiful and natural and lewd somehow and she did funny things to his brain and balls and to his whole body. They were different than the funny things Elise did to all those places but they made him feel dizzy and gave him a head rush in just the same way. He had a joint in his pocket, a nice fat one that Kevin hooked him up with, for later when they got to the high, lush mountain valley and he found a place to pitch their tent and cook dinner for them that was high and protected. He wanted them to be able to see the moon come up on one side of them and the sun go down on the other as the whole planet spun on its axis and whirled through space. He wanted them to be able to lie on their backs and see the whole universe of stars spinning right along with them. He was going to share the joint with Kate after dinner by the fire when they were ready to wind down for sleep. He didn't know what would happen next, exactly, but he knew that one way or another he was going to feed his cock to her later in the tiny tent, all night if she wanted it, which she probably would. Life tended to work out for him like that. There were so many ways it could happen. Maybe she'd fall asleep in his arms with him spooning her and throwing a leg over her, and they'd wake up just that way. They wouldn't be wearing any clothes because she would fall asleep in his arms just like that. She'd be wet and her pussy would be naked for him, and his cock would be long and curved and pumped full of blood, and hormones, and hot seed, and they'd both just take it from there. Part 6 Karin had tried to give Kate her diaphragm that morning but she'd turned her down. Karin told her to boil it in water first to disinfect it, and to make sure to use the spermicide every time, and that she wasn't judging her or saying that anything would definitely happen but that Chad was a very seductive boy and she needed to be careful. He had a way of making women cross their boundaries. Kate had laughed and rolled her eyes and tried to play it off. But now she was starting to regret it. They'd been hiking all day, straight through lunch, and they were already high in the mountains. They were both exhausted and drenched with sweat from climbing up through the humid lake air that clung to the lower slopes. But now that they were higher up the air was getting cooler and thinner and her breath was getting shorter and quicker. She felt light-headed. Chad's new mountain man look was really doing it for her, Kate thought to herself, almost laughing out loud. He was wearing a trucker's hat with a big John Deere logo and big boots, and a pair of long army green cargo shorts with lots of places to hang gear and tools and stuff like that. He was leading the way because he'd picked up a trail of dung and discarded fruit rinds and prints near the flat rock where they'd last seen M group and he was pretty sure it would lead them straight up the mountain and over the other side into the high valley with the cloud forest where Brad and Mahalia were probably waiting for them. She loved the way he looked and the way he was acting. He was pushing buttons she didn't even know she had. He was pushing them hard. He'd grown up in the mountains and Kate had been pretty sure he'd be good at orienteering and tracking and all that masculine, Eagle Scout stuff. She knew it was crazy but it was actually making her wet and swollen and jittery watching him take charge like that, and get all serious and focused, and do such a great job keeping them on track and on schedule. It felt good to have a guy take over like that and worry about all the little details and problems while she just followed him up the mountain, lost in her thoughts, her deep thoughts about Chad and Mahalia and her husband and the lush trees and the whole beautiful universe. It was fucked up, she had to admit, but it made perfect sense too. He had the most amazing body and eyes and skin, and she loved the way his cock felt in her hands yesterday morning, both of them at the same time, and he was a good companion, and he was helping her get what she wanted most in life, fame and recognition and being proved right and a deeper understanding of things. She wanted to have sex with him very badly. She wanted to have deep, intense, exclusive sex with him in all the positions she liked best, and some new ones he'd teach her, and maybe some new ones they'd invent together, for as long as it made sense. She'd just broken up with her husband a couple hours ago, and Chad was half her age and a student, and she barely knew him when you really thought about. But her body wanted to have that kind of sex with him, deep sex, to mate with him almost. Part 7 Elise looked over at Brian flipping burgers on the grill and took a deep breath in through her nose. Yummy, she thought to herself, exhaling slowly. Brian had invited everyone over to the lawn outside the women's cottage for a barbecue so they could get to know each other and bond as a group. He'd paid Roger's wife to go to the village and somehow or other wrangle enough hamburgers, and cheese, and buns and even a keg of American beer so they could have a proper American barbecue. It was just the kind of thing that a real man would do and Elise was glad to have one around for a change. She'd forgotten how physically attractive he was, with his big forearms and his tight, barrel chest and his short dark hair graying at the temples. She loved the way his butt looked in the little professor khakis he was wearing. She remembered her heart dropping and beating a little faster the first time she saw him turn around to write something on the board. No wonder all the girls raved about him so much on ratemyprofessors.com. "Hot older man alert! Hot older man alert!" . . . "Daddy I'd like to f**k!" . . . "I want to marry him and give him beautiful babies!" Elise was looking forward to sinking her teeth into one of those burgers on the grill and then later tonight she was looking forward to sinking her teeth into Brian's neck, and his chest and stomach and maybe even the spongy tip of his big cock. That's what Brian was: comfort food, a big, juicy American cheeseburger with grease dripping down the sides. She reminded her a little of her gorgeous daddy, except he wasn't related to her by blood so she didn't need to feel guilty and ashamed about being so hot for him, and he wasn't too busy being a fancy pharmaceutical executive to spend any quality time with her. She loved his slight middle-aged paunch and his love handles because they gave her something to hold onto and something to weigh her down on the mattress when he was fucking her so good it made her head spin. She was still angry with him for that serious talk a few weeks ago, the one where he told her that it was over (as if it were his decision!) and she needed to respect boundaries. She'd ended up blowing him in his office and he'd taken a picture of her with his phone adorned all over her chest and face with his pearly drops. She was still mad at him about that talk and she might have to punish him a little before she got him off tonight. She was watching him chat and joke so casually and easily with Sanjana and Kyle and Pamela as they hovered around him and enjoyed their beers. He was doing his awesome older guy routine and they were eating it up. Pamela was saying that she hadn't had a burger since she went to Top of the Hill after spring finals and she was dying for one. And Kyle started telling some story about jumping through a bonfire on the corner of Franklin Street last February when we beat to Duke to win the conference. He was drunk off his ass and his shirt was hanging out of his back pocket and it ended up catching on fire. Brian was laughing and doing his awesome older guy routine and it was making Elise wet. She could tell it was making Sanjana and Pamela horny too. She'd told them about how good he was in bed, and what a dog he was for coed pussy, and they had some plans for later tonight in the bunkhouse or the common room, however it played out. Brian looked up from the grill and spotted her. She looked straight back at him and smiled knowingly. She loved that little sparkle in his blue eyes, like he knew so many amazing things and he was dying to teach them to her. She was all dressed up for him in a tight sleeveless black top and a shell necklace and a tight olive skirt that was cut at a conservative length but still showed plenty of her long, toned legs. She had her blonde hair down to her shoulders, not in her usual short ponytail. She wanted to look older for him. It had really hurt her and pissed her off the way he'd talked to her a like a little girl that time in his office when he tried to break it off. She'd dressed up for him so she'd look older and she'd even put on the black lacy bra and panties he loved best, the ones he'd given her as a special present for getting an A in his class, and later tonight, somehow or other, she was going to make him peel both of them off her body and lick and kiss and suck the sensitive bits underneath. They were going to fall asleep in his bed together, and they were going to wake up naked, and she was going to put his cock in her pussy and ride it for as long as she wanted. Part 8 Kate and Chad were lying on their backs near the fire together under a sky full of stars. She could hear the beetles chanting in the forest down below. Chad had found a high flat grassy area to pitch their camp in and it had a perfect view of the misty forest on one side with the sun going down behind the clouds and making them glow red and casting a warm light on the wet trees and the mist, and on the other side they had a view straight down the mountains to the blue lake with the crescent moon still low in the sky. Chad insisted on doing everything. She tried to help him make camp but he said it was quicker and less confusing if he just did it himself. She could rest and plan the route for tomorrow if she wanted. Kate sat with her back to a tree trunk and studied her map and made notes and watched him the whole time. Camping in a high rain forest could be tricky but Kate could see right away that Chad knew what he was doing. It probably wasn't that much different than camping high in the Appalachians, she thought, in late spring when everything was wet and dripping and squirming with life. Chad had his shirt off and Kate was really enjoying herself. He spread a tarp over the damp grass and lit citronella torches all around the edges to keep the insects and lizards and snakes off and then he pitched their little two-person tent on top of the tarp. He arranged a mosquito net over it and then he brought their sleeping bags inside and zipped the tent and sealed the mosquito net shut tight. He built a fire on a flat rock away from the tarp a little, watching the clouds a while to see what the wind was doing, and then he cooked them dinner, and arranged some flat stones as little chairs for them, and called her over to eat. They ate without saying much. She couldn't even remember what the food was but it had tasted delicious and she'd gobbled right down. They both had. Now they were both lying on their backs with their hands behind their heads looking up at the stars. Kate turned on her side and faced him. He was wearing his tank top again but she could still see a lot of his bronze skin all around his neck and shoulders and chest and armpits. She took a deep breath in and smelled him. "So what position do you play in soccer, anyway?" Chad turned on his side and faced her. Kate was wearing a low cut, loose little sweatshirt thing with a wide neck and with no bra underneath and a pair of silky little running shorts with no underwear. It was her most comfortable outfit to sleep in and the only reason she didn't wear it every night was because it always drove Brian crazy. He could never keep his hands off her and they always ended up screwing like monkeys half the night. She wasn't always up for that so she didn't always wear it to bed. But she'd packed it last night at the last minute and now she was glad she had. She knew she looked crazy cute in it and she could tell Chad was enjoying the view. "Uh, well, defensive midfielder, if that means anything to you, sometimes they call it the pivot, or the hub." Kate nodded at him seriously. "So what does the pivot do? What's his job?" Kate liked sports and she was genuinely interested, though she didn't know much about soccer, other than she loved what it did to a man's body when they played it. How thin and lean and strong it made them up top, how powerful and solid through the hips and butt and legs. Chad looked like a pagan god or something lying on his side like that. His legs were like tree trunks and his whole core was so solid and that was why he had such amazing balance and agility and why he moved so gracefully, like a dancer almost. She loved the way he was looking at her. She loved that her body, in her cute outfit, could make a young guy with a body like Chad's, a perfect male body really, so hot and excited and nervous almost. "Well, uh, the pivot is like the center. He stays between the defenders and the attackers and makes sure that everybody is organized, and that the ball is moving quickly and smoothly all around the field. You have to be aggressive with your passing because the attackers need to get the ball quickly before the defense is set, and you can't make a mistake because if you do the defense will be exposed and it will be your fault. It's a hard job. You have to be rock solid. You have to keep the whole team balanced." Kate was nodding at him and smiling. She loved it when he opened up to her like that and even started rambling a little. He was a very interesting guy, and she was very attracted to him, and she wanted to know more about him. She loved that he knew he was good at things and that he was proud of it and that he took such pleasure in it. "It makes sense that I'm good at it. I've always been the organizer like that, the one who had to keep it together." It was everything Kate could do not to take him in her arms right then and she would have if she thought for a second that she could keep it clean. She didn't want to start molesting him or anything when he was trying to talk about his past like that. But he was so sweet and muscular and he smelled so good. It made her head swim. "You had a pretty rough time with your mom growing up, huh?" Chad looked up at her and nodded. He turned on his back and then he sat up suddenly. He sat there with his knees to his chest looking out over the lake and the valley and the camp far below. "So what's going on with you and Professor Phare, huh? Are you guys breaking up or something?" Kate shook her head and laughed a little. She was surprised he'd asked her straight out like that, but it made sense when you thought about it. She sat up next to him and pulled her knees to her chest too. The crescent moon looked like a curved sword it was so bright and sharp against the dark sky. "I guess you could say that. We'll always be close, and we don't know exactly how it will play out, but yeah, you could say our marriage is pretty much over. It's been coming for a long time and I'm glad he visited because we had a very honest and direct talk this morning and we both agreed that we need to move on." Chad looked at her out of the side his head and nodded. He wasn't sure if he could ask the next question. "Did he really have an affair with Elise? Sorry, I shouldn't have asked, its just Elise told me this morning and it kind of upset me. I don't know why but it made me feel angry for some reason, hurt almost." "It's okay. I understand, believe me." She rolled her eyes at him and took a deep breath. "Yes, he did have an affair with Elise, and he's probably still having it to be honest. They're probably having it tonight in fact. Does that disappoint you? To hear that about Brian? You looked up to him a little, huh? Chad was nodding and looking away from her a little. She could tell he was really upset. Brian had really hurt him by fucking Elise like that! She scooted over behind him and got on her knees and started rubbing his shoulders. She did it almost without thinking. It was so natural to react him to that way when he needed her like that, almost automatic, like a reflex. She worked the muscles between his neck and shoulder blades for a minute or so and then she sat down on her bottom right up against him and held him between her legs. She leaned her head against his back and held him around his chest with her arms and started rocking him a little. She'd never done that to a guy before but it seemed so natural and familiar to her all the same. Advanced Primatology Ch. 09 "Don't be too hard on Brian. It'll make you crazy if you build people up in your head like that and then get all disappointed when real people can't be perfect. Brian's not a bad person. He just wants things that he's not supposed to want, and he's an alpha so he can pretty much always get them. You're a primatologist, right? You can't really blame him when you think about it that way." She got back on her knees and started working his shoulders again. "What do you think Mahalia and Brad are doing right now, huh?" she asked him. She was enjoying the feel of Chad's muscles in her hands as his shoulders and neck started to relax. "How do you think they're feeling?" Chad thought about it for a second. "I think Brad's feeling psyched!" he blurted out, and they both started laughing. Kate was glad he was facing away from her because she was blushing from head to toe. "O yeah? Why is he so psyched? Huh tiger? What's he so excited about?" She started working his shoulders a little harder and deeper. "He's got the most popular female all to himself, and she's got the most attractive body, and she probably knows the best places to go for a week or so of uninterrupted mating and grooming and bonding and all that, and at the end of it she's probably going to be pregnant with his baby, and if history's any guide, if it's a little male baby, it has a pretty good chance of growing up big and strong and being the next alpha! He's fulfilling his destiny out there. He's doing exactly what nature designed him to do and it's making his whole brain and body feel incredible." Kate laughed out loud as she worked his neck with her fingers "You sound like you know him pretty well," she teased him, scratching his neck a little. She went back to working his shoulders. Then she had an idea. Before she could think twice she reached down and pulled up the bottom of his tank top. He hesitated for a second and then raised his arms and she lifted it right off him. His shoulders were deep bronze and they were densely muscled with little ripples all over that moved whenever he moved and his scent was pouring off his undershirt in her hands. She caught herself smelling it a little and tossed it aside quickly. She could feel the little drops of moisture starting to form inside her, and she could feel the blood starting to fill her labia and lips, and she could feel her whole sex starting to swell. Just the sight and scent of him could do that! She started to work him again with her hands. "What do you think Mahalia is feeling? Huh big guy? Got any ideas about that?" Chad took a deep breath in and held it for a minute while he thought about it. "I don't know what she's thinking," he answered, letting his breath out in a rush, "I don't understand her very much. What about you?" Kate took a deep breath in and pressed deep into his shoulders and then relaxed her hands. She was rubbing her hands gently across his back now. He was sweaty from making camp and cooking dinner and from the fire and her hands were sliding across his muscles and vertebra and shoulder blades. "I think she's feeling excited too. I think she's really hot for Brad and she's really excited to mate with him and bond with him. I think she's relieved that she won't be mounted 100 times by all the males in M Group in the next week, and I think she's planning to enjoy herself with Brad. She's checked out his penis and his hair and his scent very carefully, and watched his behavior very closely, and she likes what she sees. But I think she's scared too. I think she's nervous. She's alone with him now and he's much bigger and stronger than her so there's not a lot she can do if he decides to dominate her. And more than that she's scared that the older males might find them and it will get violent and she and Brad might get seriously hurt. I think she's excited but cautious." Chad nodded. It all made sense. He turned around suddenly, in that graceful way he had, and sat facing her on his knees. Kate's heart was hammering against her chest. His face and lips were so beautiful and youthful and his chest and stomach were hard and rippled all over. He was looking right at her with his deep blue eyes, and his long black bangs were hanging down over one of them, hiding it a little. "Can I ask you something and you promise you won't get mad? Promise you won't think I'm a bad person? I want to do something with you, and I want to tell you what it is, but I don't want you to think I'm a bad person." Kate nodded, a little nervously. She had no idea where this was going. Chad reached his hands deep into his pockets and fished around for something. He pulled them out and he was holding a lighter in one hand and a joint in the other, a big fat one. "Do you ever smoke weed, Professor Morgan? I really want to smoke this joint and get high with you. It's a beautiful night, and this is very good weed I assure you, and I promise it will blow your mind." Kate smiled wide and nodded her agreement. She didn't even think about it. It was too adorable the way he asked her. She hadn't been high in ages, maybe since back at Berkeley when she was a grad student. She remembered smoking a joint with Brian and another couple at some yoga retreat she'd talked him into going to with her one time. She remembered that weed always made her extremely horny and adventurous sexually and she always had amazing orgasms when she smoked it. They'd ended up having sex with another couple in the room for the first and only time and Kate had cum hard when she realized the other guys was watching her. Chad held the joint to her mouth with one hand and the lighter to it with the other. Kate felt jittery with excitement. She knew that as soon as the joint parted her lips and she closed her mouth on it and breathed in and held it for a few seconds and then let it go, she knew that as soon as that happened she'd be a little more relaxed, and everything would feel a little stronger and more intense, and she'd lose a little bit of control with Chad. There was no going back. She opened her lips slightly and Chad slid the joint between them and lit the end and she closed her mouth on it and breathed in deeply, closing her eyes and listening to it spark and crackle and breathing in the sweet heavy scent with her nose while she held the smoke in her lungs. It went straight to her crotch and her breasts just like she remembered. It went all through her body. A few minutes later and they'd smoked the entire joint together and Kate was feeling no pain. Chad was sitting on the rock behind her, and she was sitting cross-legged between his legs. He was working her shoulders strong and smooth. Her loose sweatshirt was already falling off her a little and Kate rearranged it when she noticed. The sun was all the way down now and the air was cooler and she could hear the beetles and the frogs and lizards chanting loud to each other in the cloud forest below them. There were so many different sounds and they were all designed to fit together in a way that would make the males and females of each species feel wild with desire for each other, and able to find each other in the dark, and mate with each other, and reproduce. That's what the rain forest was when you really thought about it. It was like a hot, wet, lush pile of steaming sex and desire. The trees and insects and lizards and flowers and birds and primates were all tangled together and they were all calling out for their mates in their own beautiful ways, in a riot of color and sound and smell. It was intoxicating. Even without the weed it could have put her in a deep trance. Chad was working the shoulder muscles around her neck now and his fingers were spread wide, and every time he worked her shoulders with his fingers they were a little further down the front of her. Her sweatshirt was riding a little further down her chest and shoulders every time, just a little, and she wasn't even thinking of stopping him or moving him or anything. She knew exactly where this was going and it was the right moment and she was so ready for it to happen. Her nipples were as plump and full of blood and hormones as she'd ever felt them and they were sticking straight through her sweatshirt. She was waiting for Chad to take her breasts in his big hands and just caress them and squeeze them all over because she could tell that with all the weed and excitement and sexual tension they were going to be really sensitive and it was going to blow her mind. Part 9 Elise had Brian right where she wanted him. He was practically eating out of her hand. She and Sanjana and Pamela were all in the common room of the women's cottage—the man's cottage now—and they were all feeling no pain. They'd drunk practically a whole bottle of some expensive vodka that some big Russian oil executive had left with Roger after staying at the lodge, and they'd smoked a couple pipes full of Kevin's best weed too. Elise had traded him a blow job for the rest of his weed that morning before he left with Jess, making sure to tease him about making sure to do a good job keeping her warm and safe in the tent at night. She'd done such a good job teasing him and blowing him and letting him cum on her little tits that when she asked for a supply of Viagra as an extra bonus he handed it right over. Brian was too drunk and stoned right now for it to have much effect but she'd make sure to feed him some in the morning. It was going to be fun times at the lake for the next few days. Brian was passed out on the sofa, or at least pretending to be. Sanjana and Pamela were sitting on the floor next to him with their backs against the couch and their legs spread a little and their hands inside their tiny, pastel-colored shorts. Elise was reading them their favorite BDSM novel on her phone and they were almost to the part they liked best, the part where the alien scientist gets hooked on some fat teenaged cock and has to decide whether to return to her home planet with his potent seed or stay on earth and fuck him happily ever after in her office with all the ropes and pulleys and clamps and such. She could tell Brian was awake, and she could tell he was enjoying the story too, because he kept taking little peeks at Sanjana and Pamela and Elise from behind his forearm, and because his hand had managed to find his way into his Khakis and somehow or other they were unzipped now and unbuttoned too and he had his fat cock in his bare hand. It looked like a real handful, and mouthful, and pussyful and everything else and Elise couldn't wait to have it inside her. She was sitting on the chair across from Brian and he was looking right at her and stroking himself long and slow. Elise had her feet up on the footrest and her legs spread a little so he could see right up her skirt to the black lacy panties she was wearing just for him. She had her phone in one hand and her other hand was playing with the inside of her thighs, massaging them slowly. She was looking right back at him and they were both smiling. Pamela had her eyes closed and she was fingering herself harder and she always looked gorgeous and lewd when she was about to cum like that. But Sanjana had her eyes wide open and when she realized where Elise was looking she turned around and saw Professor Phare's cock practically right in her face. Elise watched her head snap back a little in surprise and she watched her take a deep breath and reach her hand forward to his balls and start to rub and caress them. And she watched her get up on her knees and straddle Brian on the couch while he stroked himself and looked up at her. And she watched her bend down to him and hold his cock by the root and lower her mouth to it and take the fat head between her lips, swirling her tongue around it, and she watched Brian close his eyes and groan. Part 10 Kate was lying on her back in the tent breathing hard and staring up into space. She'd just cum hard with Chad's cock inside her and he'd just emptied his balls inside her pussy. He was lying next to her on his stomach breathing hard too. She couldn't believe it. She'd wanted him to—hell, she told him to—but she still couldn't believe it. She loved the way it felt hitting her cervix like that, so thick and bountiful and kissing and splashing her all over. Her whole body was still tingling. She shuddered replaying every detail. One minute she was smoking a joint by the fire with him and the next minute he was massaging her shoulders and copping nice feels of her breasts and nipples through the wide neck of her sweatshirt, both of them pretending it wasn't happening. And before she knew it she was in his lap with her sweatshirt off and her breasts and nipples in his mouth. He was sucking and licking them and even biting them one after another, and brushing his stiff beard all over her chest, and she was playing with his hair and massaging his scalp a little and grinding her crotch against his long shaft through the thin running shorts. He'd managed to unzip his cargo shorts somehow and when she looked down she saw his beautiful naked cock launched up to her, long and curved and thick with veins popping out all over it, blue and full. She was leaning into him and pinning his cock back against his stomach and gliding her lips across it through the silky shorts. He moved to stand up and she wrapped her legs tightly around his hips to help him lift her. She shouldn't have bothered. He was so strong he could do anything he wanted with her. She kissed him full on the mouth, wet and hot, twisting her tongue around his. Their mouths were a wet mess of saliva and sex and desire all twisted together and it felt wonderful to just slither her tongue through his mouth and let him do the same. He carried her over to the entrance of the tent and unzipped the mosquito net and bent down and laid her flat on her back in the tent. He did it so gently and gracefully and it made her feel so hot. He was so strong that he could carry her around like a little rag doll and arrange her just the way he wanted. He zipped the net shut behind them. It was darker inside the tent and a little hotter and Kate's heart was hammering. Chad got on his knees between her legs and peeled her little running shorts right off her. She lifted her ass up to let him. She couldn't wait for what was next. Whatever it was. It was up to him now. Chad was on his knees between her legs and she was flat on her back and he was looking her up and down, inspecting every inch of her. She was fiery red all over. It felt like his eyes were burning her. He leaned forward and did a little half pushup over her and kissed her full on the mouth and then looked down at her again, appreciating the swell of her breasts and the curve of her hips and the dark brushes between her legs. "You look beautiful," he told her. He meant every word of it, of course, and the little tantric chick had taught him that you should always begin that way to get a woman to trust you enough to put your face between her legs, which was what he was about to do. He leaned down and kissed her full on the mouth and on the neck and on her collarbone and shoulders and then he sat back on his knees and looked down at her, smiling at her a little cocky. It made Kate's pussy so wet and swollen when he looked at her like that, so sure of himself and his charms, and what he could do to a woman. He spread her legs and looked down at her and Kate blushed an even deeper shade and tried to cover her sex with her hands. Chad wouldn't let her. He tossed them right aside. "Don't hide it from me. You have a beautiful pussy," he drawled at her. "I love how dark and thick your hair is and how thick and luscious and red your lips are." He had his hand between her legs now and his fingers were caressing her lightly, almost carelessly. He knew it was a little corny but the tantric girl had taught him that you always had to tell a woman that her pussy was beautiful too if you really wanted to go down on her properly, to really make her open up for you. He was raking his fingertips through her dark curls with one hand and caressing her luscious lips with the other and they were getting more and more swollen and wet and parting wider and wider for him. She was like a lewd, red tropical flower just blossoming in his hand. The weed had hit him pretty hard and he was planning on really enjoying himself. Her pussy was like a blood-red camellia or something and he was like a gardener or a botanist and he was coaxing her open with his hand. Her lips and folds just kept swelling, and moistening, and parting to the sides until he could see the dark, dense bud at the center of her flower. It was hard and shiny and calling out to him and he knew that the part he could see was just the tip of it and that it extended deep inside her and it was filled with millions of nerve endings that the right guy with the right technique could turn on and light up and the current would start coursing through them. He was looking down at her and telling her that her pussy was like a beautiful red flower and could he please just have a little sniff and taste of it, just a little, and she was nodding up at him and breathing hard with excitement. Chad scooted back on his knees and eased himself down on his stomach with his face between her legs. He put his finger in his mouth and made it nice and wet and slippery with his saliva and then he reached slowly for her folds. He probed her a little with his middle finger until he found the spot where she was wettest and then he coated her all over with her juices and oils. He brought his face close to her and drank in her scent, sighing as he exhaled. "You smell amazing" he told her, smiling up at her with his blue eyes, "so sweet almost, and delicate." She was high as a kite from the weed and she'd never had anyone talk about her pussy like that before and she was eating it up. She couldn't wait to feel his tongue and lips against her. Her brought his mouth to her sex as his fingers gently pulled her outer lips apart and then he leaned forward and looked at her tiny inner lips closely and told her how delicate and pretty they looked. Then he parted them with his tongue. He gave her a big kiss with his full mouth, just covering her whole crotch with it and smacking his lips, and then he pulled his face away to look at her again. She groaned and squirmed her ass on the sleeping bag, writhing in pleasure. Chad brought his mouth to her inner thighs while he used his hand to baste her skin and her womanly legs all over with her wetness. He was kissing and licking and nibbling her thighs all over and it felt amazing and his face was coming so close to her pussy. Every time she wanted him to just devour her straight down. She wanted to grab him by the hair and force his mouth right onto her. But every time he pulled back from the edge and drew little patterns all over her thighs with the tip of his tongue, like he was writing her name and his name on the inside of her thighs with his hot red tongue and the letters were burning into her and his saliva was steaming off her skin. She was so ready to be eaten and she was so hot from being teased this way and she didn't know what she wanted him to do next. He kept coming right up to the edge of her lips with the tip of his tongue and then floating away from her and when she looked down at herself her clitoris was red and glistening and she swore it was throbbing a little. Chad was tonguing the little crease right where her leg met her pussy and he was nuzzling his face into her bush and breathing in her scent and breathing out hot air through his nose, all through her curls. He was brushing his lips against her slit, barely touching her, but breathing on her and brushing against her, just a little, and she wanted to be kissed and licked by him so badly that she took his hair in her hands and started bucking her hips up toward him. She was straining to make him bring his mouth and lips and tongue closer to her and she had her hands in his hair and she was pulling it a little and squirming her ass. She sighed with relief and gratitude when he finally put his mouth right over her and pressed down on her and kissed her and parted her with his tongue. Advanced Primatology Ch. 09 He kissed her gently from her clitoris to the bottom of her slit, up and then down again with little butterfly kisses. She started bucking her hips again and mashing his face into her crotch and trying to make him kiss her harder. And then he did and she groaned out again and squeezed his face with her thighs. "O yeah, baby, just like that. Kiss me just like that. You're doing such a good job making me all hot and wet like that." Chad was kissing her harder, all over her lips, and then he parted them with his tongue again and started licking her up and down, all along her folds and all through her swollen pussy flesh until every inch of her was slick and glossy with his saliva and her juices. She loved it when he breathed in deep and smelled her like that and started kissing her and tonguing her again. She knew she had the scent of a woman in her prime and he knew that her scent was making him crazy with lust. She was smiling thinking about how hard she was probably making him and how good he was going to fuck her after the preliminaries were over. He spread her legs wider and stuck his tongue out long and fat and started plundering her with his tongue. She hadn't expected it and it sent little shock waves from her groin all through her body in expanding circles. It was like there was an earthquake in the center of her groin and the shockwaves were rocking her whole body, tearing down her walls. He had his tongue all the way inside her and her lips spread wide and delicately with his fingers and he was fucking her with his tongue so carefully and skillfully but forcefully too. She was bucking her pelvis and hips and raising her ass off the sleeping bag to meet him and her clitoris was practically screaming at him in desperation by now, desperate for attention. She looked down and saw that it had burst its covering and it was red and shiny and waiting for him. He saw her looking down at it, and he knew what she wanted. She was hot and flushed all over and there were beads of sweat breaking out on her forehead. He brought his tongue all the way up through her folds and felt for her hard bud with his tongue, carefully and gently, and when he found it, he pressed the fat part of his tongue hard against it and held it there while she squirmed and wriggled her hips and her pearl slithered against him. He pulled the lips apart again, exposing her, and started flicking her with his tongue. He kept flicking her and flicking her and you would have thought he was a snake or something the way he did it so lightly and quickly. Her legs were shuddering and they were still glistening with her juices and her stomach was tensed and she had her fingers all through his hair and her ass kept rising up toward him. She couldn't keep it still. He made his lips into an O and took her whole clit inside his warm wet mouth and started sucking on it, so gently, like a little baby monkey at its mother's teat or something. He looked up at her and she nodded down at him and squeezed her legs around his head a little and he started sucking her harder. Her orgasm started rising inside her, so fast and big and heavy it surprised her, and her pelvis shot up high in the air so she could ride it out. Chad rode right along with her. He was hanging on to her and letting her ride it out with her pelvis and hips while he kept his hot mouth right over her and kept sucking her with his lips. "Don't stop baby! Don't stop sucking me like that baby," she kept saying to him, over and over, while she bucked her pelvis wildly and he tried to keep from falling off. He was doing such a good job riding her with his mouth and sucking her with his lips. She thought she was at the peak and she thought she was about to drop straight down the waterfall but then he did something amazing and she straight up to a new peak, higher than before. He took two fingers and slid them inside her, slowly at first, and then a little faster when she started to throw her pelvis back at him to meet his thrusts. She had her ass in the air and her pelvis thrusting and he was sucking on her clit so good and fucking her with his big hand. He was fucking her so rhythmically and smoothly and letting her set the pace and her pussy was like a volcano now and her juices were all over his face and chin and he was smiling up at her with his eyes, so cocky and proud of himself. She was flushed red all over and her nipples were sticking straight up and her tits were bouncing so good and she was trembling from head to toe. He was looking at her like he knew all her secrets now and her body belonged to him, like all the other female bodies that he'd been given before, and he was going to take her to heights she'd never dreamed of. She was in his hands now. It was out of her control. Her pelvis and stomach and legs were trembling and her nipples were like fat buds and when he reached up and pinched them she fell straight down the foaming waterfall and landed hard and sudden in a deep dark pool. It was a few seconds before she realized where she was, and clawed her way to the surface, and took a big gulp of air. When she came to her senses Chad was still on top of her and her legs were still wrapped around him. He was looking down at her and her nipples were still hard and she loved it when he gave her that little cocky, self-satisfied grin and bent down and took them in his mouth, one after the other. The tip of his cock was right up against her and her outer folds were still wet and open. He kissed her full on the mouth, delicately at first, and then hungrily when he saw she was ready for him again. He looked at her and held his cock by the root and she nodded at him and dug her nails into his chest. He fed it right up inside her, centimeter by centimeter, just sliding it right in. "Ohhhhh Chad. Ohhhhhh Jesus that's good." He smiled down at her complacently, feeding the tip of his cock to her so slow and sure. "I want to fuck you so bad, baby. I want you to fuck me so hard and good. But we have to be careful. I'm not on the pill and I don't have a diaphragm or anything, okay stud? And you are a very potent boy I can tell, and you've got big balls full of cum for me, and we have to be very careful. Brian and I were trying to have a baby and I'm not using any protection at all." Chad was smiling at her knowingly and fucking her with his tip, real gentle and slow. He loved this part. He loved the part where they told him over and over how dangerous it was and how careful they had to be and he loved the way it made them so wild and hot when they reminded themselves of the risk like that, and reminded him of it too. His cock was as long and thick and hard as it could be possibly be. He was at the physical limit of arousal and desire. "I'll be careful, Professor Morgan. I'll be careful while I fuck you with my big cock and make you cum with it." Kate tried to slither away from him a little as she dug her nails into his tight bottom. She loved being teased and taunted and even dominated like that. She loved the way that a big cock could make a guy so confident and even arrogant like that. He was very confident that he could satisfy her with his big cock and that made her confident too. She was dying to be satisfied by him. He had his eyes closed a little and he was fucking her a little deeper now. Sliding himself all the way inside her and holding himself there and letting her enjoy the feeling of being filled up like that and then sliding himself back out. "I want you to fuck me with it, baby, and I want you to make me cum with it. But you can't cum inside me, okay tiger. You can come anywhere else you want to but you can't cum in my pussy. You can cum on my breasts and my stomach or in my mouth or all over my ass but you can't cum in my pussy." Chad was holding himself above her with his powerful arms and fucking her hard now and she was fucking him hard back. They'd picked up the pace without even meaning too. All that talk about being careful was making them both wild with lust and making them wild and careless. He was nodding down at her and smiling. "I'll be careful while I fuck you hard Professor. I'll fuck you good and hard and then I'll cum wherever you want me to. I'll be really careful. Just relax and lie back and let me fuck you good and hard now." Kate wanted him to so badly but she still had reservations. She was remembering him cumming so hard and long and plentifully inside Ellen's pussy on the floor the other night and she was afraid of what might happen if they lost control like that. She didn't know if it was a dangerous time for her. She decided to tease him a little and let her know how serious she was. "O yeah, big guy? Like you were careful with Ellen in the common room the other night? Will you be careful with me like that?" As soon as she said it she realized she was totally busted and she blushed fiercely from head to toe. "What do you know about that," Chad drawled at her, tauntingly. "Did Ellen tell you something about it? Did she tell you that she begged me to cum inside her and that I filled her up so much that it was dripping out of her? Did she tell you how much she loved it and how hard she came?" Kate shook her head and blushed. He was fucking her so deep and powerfully and smoothly and her pussy was completely open to him and she was as lubricated and aroused as it was possible for a woman to be and he was still stretching her wide and probing her deep. She felt like she was right at the limit of how much cock she could take inside her. She loved it. "No she didn't tell me, " she smiled up at him wickedly. He was driving her insane with lust and she wanted to do the same for him. "I watched you fuck her. I watched you fuck her, okay stud? I watched you fuck her and it made me so hot and I fucked myself with my hand and I came so hard. But I wanted it to be your cock so bad. I wanted your cock in my pussy instead of in Ellen's. It made me so jealous." "It's okay, darling," he drawled down at her. "You've got it inside you now. You've got everything you wanted." He had her arms stretched over her head now and he was holding down her wrists and lying flat on top of her and shoving his cock all the way inside her and holding it there, pulling it out just a little and then slamming it back in hard so his pubic bone hit hers and her firm breasts bounced just right for him, so ripe and high on her chest but so heavy and womanly all the same. He loved to have a female on his back like that with her chest bouncing just right, and she was the sexiest female he'd ever had underneath him, no doubt about it. She made his cock the hardest and longest and fattest and she made his balls feel the most pleasure as they filled with hot seed from the sight and smell and feel and taste of her. "That's right stud. You're giving me everything I want. But you still can't cum inside me like you did with Ellen. You can't do that. Are you ready to pull out now and jerk off for professor and cum all over her? I love being covered with seed like that by a big strong man." It was tempting, but Chad wasn't ready to pull out of her yet, not by a long shot. "You've got to pull out now, stud," she gasped. She was starting to get nervous. She paused for a second and decided on a little white lie. "You've got to pull out and cum on my tits because it's a bad time for me, okay?" Chad shook his head and kept right on fucking her. Kate looked up at him, a little alarmed now, as if she'd suddenly realized that he was in control and that there wasn't much she could do if he decided to just take what he wanted from her right now, to fill her up with his seed. She knew that was his kink. She'd watched him enough times, and talked with Karin and Jess about him enough times, to know that very well. "You've got to stop now baby. It's too risky." Chad was shaking his head and fucking her deep and slow but building up rhythm too and her hips and breasts were rocking. "It's not a bad time," he told her, almost groaning it out. "You had your period on the full moon. Jess told me. And that means you won't ovulate until the new moon, the dark moon, and that's like five days from now. That's like five days from now and it's not a bad time and we can fuck all night if we want to and I could even cum inside you and it wouldn't be dangerous." Kate's head was spinning. Had this kid seriously been plotting her cycle in his head the whole time he was seducing her, and the whole time they were fucking, and trying to work out whether it was safe or not? Had he seriously been collecting information from Jess like that, and filing it away, and was he seriously telling her that he knew more about her rhythms and body than she did, and that he had it all covered? It was making her so hot for some reason. The level of desire and fascination that a guy would have to feel for a woman to pay attention to her cycles like that, and remember them. She wanted to believe him. She wanted him to keep right on doing what he was doing, wherever it led them. It was so tempting to just lie back and trust him and let him worry about the details. He was on his knees in front of her now and she had her ankles on his shoulders and her ass in the air and he was fucking her so deep and so good with his beautiful, long cock and his big heavy balls were swaying and slapping against her. She didn't know how it happened, how she ended up in that position with him. She'd just followed his lead. He was hitting her g-spot every time he thrust into her and then again on his way out and every once in a while he was thrusting inside her a little deeper than that and hitting another spot inside her, a spot way down deep inside that she'd never felt before. Maybe it was her cervix. She'd read about that but she'd never believed it. He was fucking her deeper and deeper and hitting the deep spot over and over now and when her orgasm started it was a whole new kind. It came on so fast and so hard and so intense. He had one hand around her ankle and the other on her dark curls and he was massaging her clitoris with his big thumb. The tiny muscles all along her pelvic floor were contracting and pulsing, deep down inside her, and the nerve endings all along her canal were white hot and pulsing with current and she felt a wave of fulfillment and gratitude and deep lust wash over her. She felt utterly filled with a big wave of deep fulfillment and desire and she was singing out for Chad. "oooohhh god, oooooohhhh god" Her hips started bucking again and he started riding along with her again only this time he was trying to keep his cock buried up to the hilt inside her while she came hard all around him. He loved this kind of orgasm, for him and her. The deep kind you could only get by getting a woman really aroused, usually with your mouth, and then fucking her very skillfully with a very big cock, and only when it was raw. Her eyes were half-lidded and dreamy looking and she was riding out her orgasm and squeezing his ass with her hands and pulling him into her. Then she surprised him. "That's right, baby. Fuck me just like that. Fuck me just like that with your big cock and make me yours, okay stud? Fuck me just like that and cum inside me and make me yours, tiger. My pussy is all yours. It's all yours baby. I want you to cum inside me so hard now baby and I want you to fill me up and I want you to keep fucking me like that all night and keep cumming inside me just like you love it. Oooohhh god! OOOOhhhhhhh fuck me!" Chad was out of his mind with lust and surprise and confusion. It was like a dream. Her face and her pussy and her breasts and her whole body felt like they were made for him, designed by god or evolution or the universe to cater to all his deepest and most powerful desires, and now she was fulfilling his deepest fantasy. She was telling him to do exactly what he wanted to do, begging him even. His kink was her kink. He realized that now and it sent a rush of electricity through his nerves. She loved it too. The danger and the rush and the irrationality of getting taking over by lust and instinct like that and letting their bodies take the lead. Chad held himself all the way inside her and enjoyed the feeling of her swollen flesh and wetness and tightness around him while she bucked her pelvis and clawed his ass and told him to cum inside her hard right now because she wanted it and he wanted it too. And then he did it. He clenched his ass and closed his eyes and tried to relax his stomach and his whole groin. He held himself all the way in and enjoyed the feel of it and then he exploded inside her. His balls pulled upward and started pumping like mad and he just exploded inside her, jet after jet of thick white seed coating her all over and shooting up inside her. She had her mouth open in a big O and her thighs were trembling and she wasn't making any sound at all as he just filled her with his seed. He leaned down and kissed her again and they both kept right on cumming and she was clawing his back like a wild cat in heat and she was already full of his hot seed. The next thing he knew he was laying next to her on his stomach breathing hard and she was lying on her back breathing hard and staring up dreamily into space. He rolled over and took her in his arms and she spooned up into him and they fell asleep naked in the little tent just like that with the beetles chanting all around them. Advanced Primatology Ch. 10 Part 1 Kate woke up alone in the tent with the birds calling all around her, almost shrieking. She was wearing her loose sweatshirt and nothing else. Chad had gotten it for her in the middle of the night after they made love to each other a second time and drifted off to sleep again. She was going to have to be careful with this boy. She could see what Karin meant now. They'd only been together for one night and they'd already given in and let their bodies do what she'd been fantasizing about in vivid detail for the last week and a half. She shivered a little remembering how desperately he wanted to finish inside her and the way he kind of pleaded and argued with her and even ignored her and shook his head when she told him it was too risky. It was so crazy and intense the way he kept thrusting along with her, a little harder and deeper. She appreciated that he made sure they were at a relatively good time in her cycle before they both gave in, and it was sweet they way he explained it to her and reassured her. But she wasn't some bubble-headed teenager! She knew there was no such thing as a truly safe time for a guy to let himself go inside her like that, as deep as he could get, and fill her up like that, twice in one night, especially the week before she was ovulating. It was probably fine but it was most definitely not safe. It was only their first night together and she'd already woken up with her pussy fucked wide open and full of his sperm! She needed to be careful. She was the grown-up in this relationship. She caught herself thinking the word and then realized how strange it sounded. But that's what it was, really. They were in a relationship now, even though he was half her age and she was his professor and she was still married, technically. She was the grown-up and she had to make sure it didn't get too out of control. She had to make sure it ended well for both of them. She couldn't have wild sex with him like that anymore, at least until they got back to camp and found some proper birth control. She couldn't just let go and fuck him raw like that the whole time they were alone in the mountains together! She was pretty she could find some other ways to satisfy him, though, and she was pretty sure he was going to love them. She wanted to get started bright and early this morning so they could head straight into the cloud forest to find Brad and Mahalia without being distracted all day. She arranged her sweatshirt on her shoulders just so and ran her fingers through her hair to work out the tangles and give it some more wave and volume. She smiled to herself remembering how it played out the second time she fucked him. She woke up with her head resting on Chad's chest and her leg thrown over him. She drank in his scent and before she knew it she was scratching his chest with her nails and working her way down his stomach and his dark curls until she felt him stiffen at her touch. She loved the way his balls were still firm and round for her. She couldn't keep her hands off them! Somehow or other she ended up on top of him with his cock inside her again while she thoroughly enjoyed herself, trying every position and angle she liked best: placing her hands flat on his lower abs and bouncing straight up and down on him, leaning forward over him and riding him hard and smooth with her hips with her nipples in his mouth, leaning back with her hands on his knees and swirling her pelvis in tight circles while he watched her breasts swirl too and her tights abs working hard for him. That was the position that made him hardest and longest, apparently, and she loved it too. She loved the way it felt every time their pubic bones clicked together and their dark curls tangled together and brushed against each other. And she loved it when her clit started rubbing against the base of his cock or maybe his pelvic bone. Whatever it was it felt amazing. That was the position that really did it for both of them and they made love that way for what seemed like an hour. It ended with both of them cumming hard with their eyes wide open and looking right at each other. They were breathing fast. They were making little sexy gasps and moans for each other so they'd both keep doing exactly what they were doing. So they wouldn't even think about stopping or even changing the tempo because it felt so good and they needed to just ride it out. They needed to just ride it out because she needed to have his cock inside her when she came for him because it would make her cum harder and it would drive him wild. It would drive him completely wild and before long she'd feel his cock start pulsing inside her, and feeling fatter and hotter just like she loved it, and longer too so he was giving little kisses to her cervix with his plump crown. She'd be swirling her pelvis for him so smooth and slow and his cock would be pulsing inside her and she'd be cumming all over him and coating him with her oils. She'd be coating him with her oils and pretty seen he'd be bathing her insides all over with his sperm like it was fine ointment or lotion or something. He'd be shooting inside her and his seed would be splashing against her cervix. It would push her right over the edge and she'd have another orgasm, a different kind, all through her body and deep down in her core, right on top of the first one. And that's just what they did. They did it raw and smooth and passionate just like that and Chad came gallons inside her and Kate loved every second of it. She wanted to do it with him just like that over and over for as long as it made sense. For as long as it was still safe. Which it definitely wasn't. She felt cold after they finished and she asked him to get her sweatshirt from outside and he did it for her right away. He even helped her put it on. Now it was morning and she could hear him making breakfast on the little stove outside the tent. She sat up and arranged her sweatshirt just right. She unzipped the tent and crawled out on her hands and knees to say good morning. He wasn't wearing a shirt and his hair was wet and she could tell that he'd already washed himself in the stream. He was leaning over a pot of oatmeal and stirring in some brown sugar with a big spoon and it smelled delicious. She walked over to the flat rocks they were using as chairs last night and sat down on the nearest pile. She spread her knees wide and watched him until he noticed her, and noticed that she wasn't wearing her shorts, and that she was already red and swollen and moist. "Come here," she said, a little huskily. She needed to be very careful with him. How many days could sperm survive inside her? And weren't there reasons a woman could ovulate a few days early? Like if she was under stress or something? She'd always been so bad at keeping track of those things, so put off by it. But she knew it wasn't truly safe and she needed to take the edge off. Chad dropped the spoon, and stood up slowly, and walked over to her, almost sauntering. He was standing right in front of her looking down at her so pleased with himself and she was looking up at him with her big brown eyes with a little sparkle around the edges. She was smiling up at him and unbuckling and unzipping him and everything else, taking her sweet time. She laughed to herself thinking that Chad was in for a real surprise. He knew her mostly as the demure professor in her glasses and pantsuits in front of a lecture hall but now he was about to see a different side of her. Now her long auburn hair was all messy and wavy from sleeping half naked with him in the little tent all night, instead of in a tight bun the way she wore it for lectures. It was hanging past her shoulders and he was about to see a whole different side of her. She loved to please a man with her mouth, and she was very skilled at it, and she always did an amazing job. Brian had encouraged her to learn how to do it properly when she was still a teenager and she'd always be grateful to him for that. He taught her how unbelievably hot and satisfying it felt to have a man filling your mouth all the way, and he taught her lots of tricks for how a girl could use her tongue and lips and teeth to make a guy all thick and hard, and he taught her how to relax her throat once she got him that way, and breathe out through her nose so he could feel her hot breath in his curls. Chad was in for a surprise all right. She smiled up at him and parted her lips and brought his fleshy crown right up close to her. She stuck out her tongue a little and started swirling it just so. She needed to take the edge off and keep it safe for both of them. Part 2 Brian was standing at the toilet with his cock in his hand pissing gallons. His head was pounding and he was trying to piece together the night before. He was leaning against the wall to keep from falling over. He remembered Elise giving him a glass of water and maybe even a pill at some point. The sun was up so it must have been morning by then. And he remembered waking up a little later with Elise naked on her knees in front of him, worshipping his cock just like he taught her to, bathing it from balls to bulb with her little pink tongue. She was such a good student. She had good instincts, and she enjoyed her lessons, and she paid close attention to all the right details. She had an indescribable freshness and purity to her, a genuine youthful beauty that took his breath away sometimes, with her blond hair and her pale blue eyes and her radiant skin. Her smallish breasts that were shaped like no others he'd ever seen. They were surprisingly full and round and they were growing more and more womanly by the week. And at the same time she had a dirtiness to her that made him rock hard every time. After a while she stopped pleasing him with her mouth and crawled on top of him and took him inside her. She leaned back with her hands on his knees and started grinding him slowly, so lewdly, with her blond pussy hair jutting out to him and then grinding back down on him. She rode him just like that until she could feel him about to explode inside her and then she just smiled mischievously and kept riding him, leaning forward over him and rubbing her sweaty breasts all over him. She knew how a man liked to finish. She knew it felt hotter and more pleasurable and more fulfilling when a man's seed went right where it was designed to go, right up inside her. He'd told her lots of times and she was a very good student. Yeah, he laughed to himself, it had been quite a night and quite a morning and it was going to be fun times at the lake for the next few days with Kate and the other women away. He'd finished pissing and he was standing in the middle of the common room now stark naked with his cock sticking straight out in front of him. Elise must have slipped him some Viagra or something. She was a very naughty girl that way. He wondered where Sanjana and Pamela were. He could remember Sanjana giving him a pretty decent blow job on the couch before he passed out. She had definite potential, and she had big soft breasts, and he was looking forward to working with her closely. And he remembered how dirty little flat-chested Pamela looked getting herself off with her hand on the floor He noticed that the doors to the other two bedrooms were open a crack. He walked over to the nearest one and looked inside. Sanjana was sleeping stark naked on top of the white sheets. She was on her side rolled away from him with her big round brown ass perfectly displayed. Nice, he smiled to himself. He backed away quietly and went to the other door to see what other delights he might find. He pushed the door open quietly and peered in. Pamela was stark naked on her back with her eyes closed and beads of sweat on her forehead and her hand between her legs. Her tiny tits were bouncing a little and her red nipples were long and stiff and her tight stomach muscles were clenched. He could see every one of her ribs. He stood there watching her and stroking himself for a minute, maybe longer. He groaned out, lost in his pleasure and in his brave new thoughts. There were going to be some changes around the Phare lab when he got back to Chapel Hill. There was going to be a new curriculum. He was going to be rich and famous now that his new book about the dominance gene was such a runaway success and the university wouldn't say shit about anything he did if he kept the grant money and the prizes and the newspaper articles flowing. They wouldn't say a thing if every one of his postdocs and graduate students and undergraduate students was a beautiful young woman, all the varieties that pleased and delighted him, and if they all lived in his big house, each of them with a tiny bedroom of their own. And they wouldn't say a thing if he gave lessons to all of them on a rotating basis, every night, teaching them things that would make them better playmates, and better women, and maybe even better scientists too. They were training to be primatologists after all! They needed to understand the power of the alpha. They needed to understand it with their whole minds and their whole bodies. Part 3 After breakfast Kate agreed that they would make a base camp on the little bluff where they slept last night and explore the cloud forest by day. It was right on the edge of the forest and it was high enough to keep them out of the heat and humidity and insects at night. It would be better for sleeping. It was a smart idea. Chad was resourceful like that. It would be a better place to store her samples too. She told him her idea to collect urine specimens from Brad and Mahalia and bring them back to her lab in Chapel Hill to check their stress levels. She told him her new theory about "consortship mating," about why mature females like Mahalia choose to go on safari with young males like Brad much more frequently than younger females do. Her idea was that they were more relaxed and receptive when they were alone with a younger male who took good care of them, with lots of food and grooming and calm interaction, and that as their stress levels went down their fertility went through the roof. So "consortship mating" was probably a big advantage to the mature female during one of her last opportunities to pass on her genes. It gave her a much better chance of conceiving. And she was near the top of the female social hierarchy, so she had enough rank and status and popularity to get away with it! The idea had come to her when she was drifting off to sleep after the second time Chad fucked her. Her hypothesis was that "consortship pairs" like Brad and Mahalia were responsible for a much higher percentage of pregnancies and births among chimps than previous scientists thought. And she even thought it was possible that an unusually high proportion of alpha males were born from such arrangements. Either way, it was almost like the mature females were the real decision makers when it came to the all important question of which genes were passed down to the next generation, and which traits were selected for. Even more shockingly, it was almost like all the tension and violence the alpha male used to maintain his dominance was actually a disadvantage! That it made the females less fertile. That it was being selected against over and over every time a female like Mahalia slipped away with a male like Brad! "Smart lady," Chad drawled, looking right at her admiringly. Kate dropped her head and blushed. She still needed to demonstrate it experimentally, but all the evidence so far pointed in the right direction. She showed Chad how to use a pipette to collect urine from leaves and grass and how to seal it properly in a test tube and store it in the padded cooler. She put him in charge of carrying it and keeping it safe and dry. "You're carrying my whole career in that thing, okay tiger?" she reminded him. They climbed down into the valley and looked for signs of Brad and Mahalia. It was hard work in the humidity, and they couldn't see very well in the early morning mist that was still pouring off the dense foliage. It was like another world in the cloud forest with the oversized leaves hemming them in all around and the high canopy full of buds and birds and lizards that she didn't know the names of. But before long Chad spotted a nest high up in the canopy and fresh prints leading off toward a stream. Kate couldn't believe her luck! It was a large forest and she expected it to take maybe a couple days to find them. They walked quietly toward the stream. They didn't want to be too quiet because they didn't want Brad and Mahalia to think they were trying to sneak up on them. They'd be on the alert for that. The other males in M Group might form a patrol to hunt for the pair. But they didn't want to make any sudden noises either. They just needed to walk toward them calmly and let themselves be identified as humans, the boring kind who like to sit on their haunches and observe and take notes. All of the chimps in M group were used to that kind of human and they all pretty much ignored them. Kate parted the leaves in front of her slowly and what she saw made her heart ache. It wasn't Brad and Mahalia. She should have known that. There was only one set of prints leading off from the nest but she'd been too excited to look closely. There was only one set of prints but there were two chimps: a mother and an infant, still young enough to be carried around on his mother's belly almost all the time, clinging to her tightly. He was maybe a year old, and he was hanging from a vine upside down and making sweet noises at his mother while she used a short, thick branch to crack nuts on a rock and feed them to him, one by one. It was painstaking work but she did it so skillfully and patiently. She held the thick branch in her hands, just so, and pressed down on the nuts carefully but firmly until the shells split open. Then she picked up the soft insides in her fingers and held them up to him in her palm. He devoured them greedily, still hanging from his feet, and then hooted at her for more. He was adorable and the mother was obviously in love. She kept reaching up and tickling his belly and batting him from side to side gently while he clung to the vine and made happy excited noises. She was doing it to amuse him so he wouldn't get in the way while she was trying to prepare his food. But she was also doing it to help him grow up faster, to make him strong and agile in the trees. She would have her next child before long and the bond between them would loosen. She had lots to teach him before then if she was going to be a successful mother. Kate looked over at Chad. He was looking at the mother with an expression of curiosity, and sadness, and maybe even reverence. Kate had a pretty good idea what he was thinking. He was thinking of his own mother, and missing her, and wishing that she had been as dedicated and capable as this one. And she knew exactly why her own chest was aching. She'd been so ready to have a baby with Brian. It was the right time in her life. She realized that now. It was the right time and she wanted one very badly. She reached over to Chad and scratched him gently on his back. He looked at her and smiled. They both stood up and walked deeper into the forest. Part 4 I need to get my fucking head examined, Brian thought to himself. He was taking the kids over to a little cove he knew for a day of snorkeling and sunbathing and probably all kinds of sex and he was still nursing an epic hangover from all the vodka and weed last night. First thing I'm going to do when I get back to Chapel Hill, he told himself, is to hire the best shrink I can find, maybe Karin's fiancé, and get my head thoroughly examined until I figure out what the fuck is wrong with me. Advanced Primatology Ch. 10 He was sitting in the back of the boat between Roger and his cute wife Alex with the strawberry blonde hair and freckles and the little upturned nose. Elise and Sanjana and Pamela were standing in the front of the boat with their backsides displayed for him in their little pastel suit bottoms, all different sizes and styles and colors. They were standing there that way so he could look at them and enjoy them and they kept looking over their shoulders at him, and making jokes with each other, and turning back around and wiggling their backsides a little because it was all so funny and naughty and they loved to tease him and drive him crazy like that. And they did drive him crazy, no doubt about it! They drove him wild with lust and he couldn't wait for later tonight because he was going to fuck all three of them in their tiny bedrooms in the cottage. One by one in all the positions he liked best. Roger was looking out over the lake to his right, and Alex was looking to the left, and Brian was sitting between them with his legs spread, and a big smile on his face, and his long swimming trunks tented straight out in front of him. But if he was really honest with himself, if he really dug deep down inside himself beneath all the lust and excitement and the exhilarating sense of power it gave him to be so desirable to women, so irresistible, if he was really honest himself he had to admit he was feeling a little bored at the prospect all the same. Like it was his job or something. Like it was all just a little too easy to seduce them that way, and a little too much work to take all of them. He caught himself staring at Elise sitting on the side of the boat. He was trying to make out her curves in the little bikini she was wearing beneath her long button-down white shirt. He was pretty sure she had a very cute body. She was reading a book and when she looked up and caught him staring at her she blushed deep red and eyed him curiously. She'd been fucking Chad the whole trip, apparently, and some lesbian girl too, but neither of them had enough cock to really satisfy her, according to Elise anyway. She and the lesbian girl were practically a couple by now, and Chad had tried to "cure" her, but he wasn't man enough for the job. Brian liked red heads. He liked it when they had fiery red bushes, big wild ones, and when they had freckles all over their bodies, and when he had his cock inside them and they were crying out his name, especially when they were being unfaithful. Alex was kind of a redhead, come to think of it. Her hair was cut short and she had pale skin and freckles and the kind of British accent that can only come from some posh boarding school in the country somewhere. He was dying to know what kind of body she had under the flowery housedress she was wearing. He was dying to know if she had a bikini under there and he couldn't wait to get to the beach to find out. I need to get my fucking head examined, he thought to himself, adjusting himself in his shorts as Ellen dropped her eyes, still blushing, and went back to her book. Part 5 Chad and Kate were sitting with their backs against an enormous tree, deep in the cloud forest, and they were both drenched with sweat. It was mid afternoon and they were making a quick lunch out of some nuts and dried fruit and beef jerky. "What were they doing way up here, anyway?" Chad blurted out suddenly. "Who?" "The mom and the little baby boy," he answered. "What were they doing so far away from M group? Way up high in the mountains like that? Why was she on her own with the little guy?" Kate shook her head. "I'm not sure. I was wondering the same thing actually. I think maybe they're hiding." "From what?" "Well, I can't be sure exactly, but my hunch is that some of the males in M group threatened the baby and the mother took him up here to try to keep him safe and out of harm's way for a while, maybe until the males calm down." "Why would they threaten the little guy? I don't get it." "Well, I'd have to check the field logs but I'm pretty sure the mom is new to M group. I'm pretty sure she migrated from a neighboring group for some reason. Maybe the sex ratios in her original group weren't balanced enough. And sometimes when that happens, the males in the new group will murder her infant. They know it's not their offspring, so they don't have any interest in protecting it. And if they kill the baby then the female will go into estrus sooner and they'll be able to mate with her themselves." Chad nodded his head. Kate was impressed that he hadn't expressed revulsion or horror at the idea. He was calm and dispassionate that way when they were talking about science. He had lots of talent. He had enough empathy for the chimps to be able to see the similarities between humans and other primates, and that gave him real insight. But he didn't try to impose human values on them either. He didn't judge them. They had that in common. "Why won't they kill Mahalia's baby then, if she gets pregnant from Brad? Won't they remember that she wasn't around when she was fertile? Won't they realize that it's not their baby either? She's taking a big risk, isn't she?" Kate nodded her head. She was really impressed! It was a very smart question and she'd been wondering that herself. "I think she'll go back to M group while she's still in estrus. I think she'll spend a week or so alone with Brad, and give him the best chance possible to make her pregnant, and then she'll go back to the group while her sex skin is still swollen." "And do what?" Chad asked, a little surprised now, indignant even. "And do what female chimps in estrus always do, sweetie. She'll mate with all of the males in the group, and she'll mate with the dominant males most frequently. She'll copulate with them dozens of times. But with any luck she'll already be pregnant by Brad. Then the baby will be safe because none of the males will know who the father is. That's why female chimps are promiscuous in the first place. They have to be so that all the males in the group will take an interest in protecting their babies and letting them grow up strong and healthy." "So it's just a temporary thing with Brad," Chad reflected, starting to get the picture. "Isn't she kind of using him then?" "What do you mean?" The question surprised her. It wasn't objective at all. "Well, I mean, how's it going to feel for him when they go back to real life and he's at the bottom of the hierarchy again! How's it going to feel for him watching her get mounted over and over like that! She likes him because he's sweet and attentive and she can wrap him around her finger. But what about his feelings?" Kate eyed him curiously. It was so unlike him and she wasn't sure where he was coming from. "She can't afford to worry about that! Neither can he. She has to be part of the group if her baby is going to stay healthy and survive. The alpha controls the foraging range and the meat supply and everything. They'll starve if they're not part of the group. Brad understands that. She'll give him the best chance she can to be a father and then they'll go back to the group and with any luck the little baby will look just like him." She smiled at him affectionately and scratched his back again. It was sweet the way he identified with Brad. Chad nodded again and looked down, almost sadly, with his long dark bangs hanging over his eyes. He was hard to read sometimes. He showed depths of emotion that surprised her in such a young guy. He'd been through a lot in his short life and it had left deep scars, even though he was so talented and handsome and successful on the outside. She wanted to take him in her arms and rock him. She'd never felt that way toward a guy before, and definitely not with a guy she was having sex with. Almost maternal. "So it's just a temporary thing, huh?" he asked her with his blue eyes shining. "Yeah, it's just temporary," Kate answered slowly, realizing suddenly that she had to be careful with him in other ways too. He was still just a kid and she needed to be careful with his feelings. Chad nodded and looked down. Kate stood up and put her pack on her shoulders and led them deeper into the mist. Part 6 Every time Kevin looked up the trail in front of him he couldn't believe his luck. Not only was Jess probably the hottest girl he'd ever been alone with—that ass was phenomenal!—but she had an awesome personality too. They stayed up late talking the night before, and gazing up at the stars, and smoking a little weed, and Kevin was seriously in love. He even played her a little of the new demo his band had just recorded on his trusty phone with the sweet speakers and Jess seemed really into it. She sat there in her little Rutgers t-shirt with no bra underneath, and the pair of tiny running shorts she was going to wear to sleep next to him in the tiny tent, and she was bopping her head and closing her eyes and really getting into it. "You're a really good bass player," she gushed at him, and Kevin's heart just melted. She liked all the right bands, and all the right books, and she liked to go to shows on the weekends and maybe she'd come to see his band sometime with her boyfriend! And she was a kick-ass primatologist, and smart as a tack, and she was alone with him in the freakin' rainforest and Kevin felt like dying from lust, from love even. It was too bad about that boyfriend. Not that it stopped her from spreading her legs for Chad. It really burned his ass the way that guy scored all the best girls. He was probably fucking Professor Morgan right now and that lady was so hot it made his head explode. That picture of her in the bikini in Puerto Rico. Sweet Jesus. Just imagine fucking a woman like that! If Chad wasn't such a good dude, basically, he'd be completely unbearable. He gave Kevin some tips before they split into pairs and headed off to the mountains. He told him that he had to work his ass off all day for Jess and take care of all the little details, and he had to listen to her when she talked, and open up to her when she asked him questions, and that once they'd smoked some weed together and talked for a while he had to do whatever it took to let him give her a shoulder rub, and then he could just take it from there. Kevin had gotten right up to the shoulder rub part and then chickened out. Sure, it was easy if you were an all-American soccer player with muscles on top of your muscles and a monster in your shorts. But for a guy like Kevin advice from a guy like Chad could only go so far. He didn't resent him for it, much. That was part of the way Chad stayed so popular with the ladies, Kevin reflected. He didn't rub his success in the other guy's faces and so things tended to stay mellow and cool when he was around. And the ladies liked that. That was part of being an alpha, even for the chimps, Kevin had noticed. It wasn't just about having the biggest penis and testicles, and making the most noise when you beat a branch against the rock, and beating the females when they didn't toe the line. It was also about making alliances with the other males, and grooming each other and sharing meat, and giving the other dude's a shot at the really sweet backsides too. It was cool of Chad to give him that tip about working his ass of for Jess and letting her relax and have fun. It worked like a charm and he never would have thought of that himself. And it was good to be reminded about the listening part too, though Kevin was already pretty good at that. He was grateful for the advice. But to get where he wanted to be with Jess he was going to have to do it his own way. He was going to have to take it slower. Part 7 Kate was looking through the first aid kit when she found them. She was wearing her loose sweatshirt and her running shorts again with nothing underneath and she was sitting with her back against the tree while Chad made dinner on the little stove. The crescent moon was still low in the sky over the lake, a little thinner and sharper than the night before. She didn't know what it meant when she found them but it made her feel clammy and dizzy. She was looking through the first aid kit for a tube of Vaseline or something. She was determined not to go all the way with Chad tonight because she knew that the thinner the moon was the more dangerous it was for her. They couldn't go all the way. It made her feel a little giddy and excited to think of it that way. Like she was a teenager too. She couldn't go all the way with him, but there was no way that either of them was going to sleep for a minute tonight until they had hot sex together, and a big orgasm or two, and felt calm and elated in the mountain air, and spooned together and drifted off. She was looking for the Vaseline because she'd had an idea in her head since lunch and she was determined to act it out after dinner. She wanted to lay Chad naked on his back in the tent (maybe she'd keep her clothes on) and stroke him long and slow with her hands, both of them at the same time, and talk dirty to him, and tease him, until he came all over himself. She knew he probably had ideas about what do with her, and she knew that they probably involved his cock all the way inside her in some position they hadn't tried yet, maybe from behind. But she was determined to explain things to him, to explain that they had to be responsible, and, more than that, to explain how hot and dirty it was going to feel to restrain themselves until they got back to camp and got some condoms or something and could fuck each other properly. She was going to explain that to him in vivid detail the whole time she was stroking him. They needed to get a good night's sleep and start bright and early because they'd gotten lucky and found Brad and Mahalia's nest late in the afternoon after they'd given up and turned back toward camp. Mahalia was sitting on the ground on her haunches eating some fruit Kate didn't know the name of and Brad was high up in the branches building a nest for the night out of some dried leaves and grass. Kate was so happy to see them she almost ran right up to Mahalia and hugged her. And Mahalia seemed to recognize her too, and maybe she even seemed glad to see her. They watched each other for a while and then she motioned silently to Chad and they walked away. She was remembering the scene and digging through the first aid kit absent-mindedly when she found them. A four-pack of condoms. She didn't know what it meant. Did Chad pack them? Did he know they had them? Did he know they had birth control with them the whole time they were fucking last night and did he keep that secret from her? And if he did, then why? Kate felt angry and betrayed by the idea, of course, but she felt fascinated by it at the same time. She needed to get to the bottom of it. Chad was a puzzle alright! He was one of the sweetest and most caring guys she'd ever met, and he was a great listener, and he didn't seem bothered in the least by the fact that she had more power and authority in the world than he did. To the contrary, judging by how hard he'd been last night and how hard he'd cum insider her, both times, looking down at her womanly body while it shook and trembled for him in all the right places. He was so sweet and attentive but he had a real dark side. What made a guy like that tick? What made a guy so young and smart and focused develop a kink that powerful and dangerous? A kink for having unprotected sex with women when they were at their most fertile, like he did with Jess and god knows how many others? For having sex with a woman when her whole life and future were riding on it. When the stakes were as high as possible. She didn't know what it meant, but she was determined to find out, one way or another, tonight if possible, alone with him in the tiny tent. She slipped the condoms and the Vaseline into the waistband of her shorts and walked calmly over to the tent to hide them in her sleeping bag. Part 8 Courtney was sitting by the stove with Karin eating warm beans and feeling pretty disappointed if she was honest with herself. Karin was such a soulful type, such a natural beauty. Before their trip to the mountains Courtney would have bet good money that she had at least a little bit of lesbian in her somewhere. But so far she hadn't felt the slightest vibe, and Courtney had been acting pretty charming, she had to say, doing all the cool stuff she was so good at. Scouting the trail, and making camp, and cooking dinner, and being a fucking awesome listener, and a really interesting person. Karin genuinely seemed to like her but she didn't seem attracted to her at all. Fuck that guy Chad Berwick! Was it all about the big cock and the stubble and those shoulders and pecs? Was it just an alpha thing like with the stupid chimps? Was that really all it took to get a woman like Karin flat on her back with her legs spread and calling out your name? Or Ellen for that matter. She should never have agreed to that threesome with Chad back at the hotel. But she lost her confidence when he started dancing with them and Ellen started flirting with him so hard. She lost her confidence that Ellen would ever cross the line with a woman like Courtney unless there was a guy like Chad around to make it seem okay. It was probably for the best that nothing was going to happen with Karin because Courtney was head over heels for Ellen by now. She loved that girl so much it made her heart ache and her crotch ache too. Fuck that guy Chad! She and Ellen were practically a couple by now but that didn't stop her from slipping off to get a little bit of Chad's fat cock inside her every few nights or so. She wasn't cruel about it or anything, and they weren't officially a couple, but it killed her inside all the same. The first thing she was going to do when she got back to Chapel Hill was to march straight up to her bedroom and find her own cock—the big dark one—and march straight over to Ellen's and fuck her into ecstasy with it and make her pussy hers forever and ever. She'd wanted to bring it on the trip because she'd had a huge crush on Ellen ever since Professor Morgan's lecture last semester and she was dying to get to know her better. But she chickened out at the last minute. What if she got searched coming through customs and some security guard pulled it out of her suitcase and started waving it around! She would have died of humiliation. Fuck that guy Chad. He got to bring his cock everywhere. Part 9 Kate looked up and realized that Chad was staring at her, just drinking her whole body down. They were sitting on their rock chairs again next to the stove and the thin crescent moon was high in the sky now. The beetles were chanting and the frogs were croaking and the air was getting cooler and thinner. Kate sighed contentedly. Her bully was full of warm beans and dried sausage and a little piece of chocolate that Chad had kept in the side pocket of the little cooler so it wouldn't melt. He told her to open her mouth and close her eyes and fed it to her with his fingers. She closed her lips on his fingers and sucked them a little when her tongue tasted the rich sweetness, groaning out for him in surprise and pleasure. Chad was staring at her and picturing all the things he was about to do to her and Kate knew it was time to act. Now or never, she thought to herself. "So things got a little crazy last night, huh tiger?" "What do you mean?" Chad asked, genuinely surprised. "You didn't like it?" "No, silly. I loved it!" Kate corrected him, blushing deeply. "You know that. But it was kind of crazy wasn't it?" "Sure was," Chad replied, nodding his head vigorously and making big excited eyes at her. "I'm kind of hoping it's about to get crazy tonight too!" He darted his hand out and pinched her in the side while his blue eyes sparked at her. Kate squirmed away from him and slapped his hand. Advanced Primatology Ch. 10 "Easy, tiger. I'm trying to have a little conversation here." She took a deep breath and steeled herself and tried again, "I mean it was crazy the way we didn't use any protection and you came inside me. Twice. That was crazy, right?" "Oh, that," Chad answered, looking a little sheepish, embarrassed even. "Yeah, that," Kate mocked him, smiling all the same. "It's okay. It's not your fault. I'm the grown up here and I practically ordered you to do it! Think how embarrassed I feel!" Chad looked up at her and laughed, relieved. He looked so young and beautiful when his face relaxed like that and you could see the boyishness beneath his sharp, masculine features. He had gorgeous lips, full and red, like a girl's almost. "I wanted to do it too," she continued, "but it was crazy all the same! Right?" "Yeah, sure," Chad answered, but he didn't sound convinced. Kate rolled her eyes at him. This was going to be harder than she thought. "Come here," she said, pointing to the ground in front of her. Chad stood up and walked over to her and sat down between her legs facing away from her. Kate started massaging his neck and shoulders like she had the night before. "You've got a real kink for that, don't you, big guy," she asked, maybe a little flirtatiously, as her fingers played through the short hairs on the back of his head. "For what?" "Don't play dumb," she teased him. "You've got a real kink for having sex with women unprotected. You know. For cumming inside them? For having sex with them unprotected and cumming inside them when it's not safe? You've got a real thing for that, don't you big guy?" Chad didn't answer. Kate could see the back of his neck flushing bright red. She could tell she'd hit a nerve. "It's okay. I'm not judging you," she reassured him, bringing her hands to his shoulders and working them a little roughly to distract him. "I just want to understand. Has that always turned you on so much?" Chad nodded. She could feel him relaxing. "How come? What's that all about anyway?" "I don't know," Chad answered, letting his breath out in a rush. "I've thought about it lots of times and I don't really have a clue to be honest. I think it's part of the reason why I was so interested in Professor Phare's class. Your class too. It was the first time any of it made any sense at all to me." "O yeah, how come?" Kate asked, working his shoulders hard and deep, "What made sense?" "Mate selection, I guess." Chad groaned out as her fingers dug into him a little deeper. "Why a guy wants to mate with some females and not others. Why he wants to spread his seed around with as many healthy, desirable, fertile women as he can. It's evolution, right! It's what I was designed to do." "True," said Kate, still working his shoulders, "but you were designed to make decisions too. Right? You have a larger brain than other primates, don't you? I mean, you seem like a human being, for the most part." "Thanks," Chad muttered, "that means a lot." "Oh don't be so sensitive." Kate teased him, scratching his neck again. "I just mean that every guy is designed to want to spread his seed around. But not every guy has a thing for impregnating women. The idea of it doesn't make all guys so crazy! I just want to understand why it's so hot for you. I'm interested in you, okay?" Chad turned around suddenly and faced her, looking up at her with his deep blue eyes. She could see he was embarrassed. "Don't act like it's just me that has a thing for it. Don't act like it doesn't make you hot too! I was there last night when you screaming for it, remember? Why did you want it so badly? Huh?" Kate sighed deeply. She wasn't embarrassed at all. It was a fair question and she'd been wondering about it all day. "If I tell you, will you tell me?" Chad nodded. "Well," she said, breathing in deeply again and closing her eyes so she could focus, "it's partly because you are a very hot young guy and we were having amazing sex and I just got carried away. Part of it's that simple. I really like being with you, in case you hadn't noticed." Chad turned around again so Kate could massage his shoulders. He didn't want to break her stride and it was easier that way for both of them. "But part of it is just that I've gotten used to doing it that way, and I like how it feels. A lot. Ever since Brian and I started trying for a baby the sex has been incredible! I'm at my peak age for reproducing and having sex that way just opened up all these physical desires I never felt before! It was weird and fascinating. Even though we were married and had made a conscious choice to get pregnant it still felt irrational and forbidden somehow. Letting a guy cum inside me unprotected like that when I'd been so careful to avoid it my whole life. It felt so wrong in my head and so right all through my body, if that makes any sense!" "It makes total sense!" Chad blurted out. "It makes total sense to me! That's just how I feel. Believe me, getting a woman pregnant is the last thing in the world I want right now. My mom got pregnant by accident when she was about my age and look where she ended up! But physically it just feels so right somehow, even though my brain is always screaming out that it's crazy! That just makes it hotter, actually." Chad laughed out loud and Kate laughed right along with him. I could really get used to this younger guy thing, she thought to herself. Opening up to an older woman came so naturally to Chad and it tapped into something deep and unexpected inside her. It felt deeply gratifying somehow to be trusted like that, and it felt easy to be herself with him. "But it's different with you than with the other girls," he continued. "It's way hotter. I've never wanted to cum inside a woman so badly before. It was the hottest sex I've ever had. Hands down." "Easy, tiger," Kate teased him. "You've already gotten inside my shorts, remember? You can take it easy with the smooth talk, now. I bet you say that to all the girls that let you cum inside them on the first date." "No," Chad drawled, "just the ones who let me do it twice!" "Hey," Kate chided him, digging her nails hard into his shoulders. "Don't tease me for being such a slut last night. I feel guilty enough about it already. What if you really did get me pregnant? Think how I'd feel if I put us in that position! I'm your professor for crying out loud, and you're not even old enough to drink!" "Sorry, sorry," Chad conceded, still laughing, and relaxing again as Kate went back to massaging him. He took a deep breath in and held it. "But it's true, you know," he continued, letting it all rush out. "I don't think I've ever been hotter for a woman than I was for you last night. My cock felt like it was going to shoot right off me and I don't think I've ever cum that much before. And definitely not twice in a row. But it's not surprising really. It's like that every time I fantasize about you. Ever since I started fantasizing about you last semester, looking so fine in those dark pantsuits!" Kate was blushing fiercely from head to toe and kneading his shoulders with her palms. "I think part of the reason I've got such a thing for risky sex is that when a woman does it with me it's like her way of saying that I belong inside her. That I'm not beneath her. That I'm good enough to breathe the same air as her. I think it got really intense when I got to UNC. All the girls acted so superior to me as soon as they heard me talk! And all last semester you had a way of making me feel like you were better than me. You were so smart and confident and classy and you barely even knew my name even though I fantasized about you every night." Kate needed to keep her focus but she wanted to see where this was heading all the same. She hadn't expected the conversation to get so intimate so quickly, and so dirty at the same time. He was full of surprises, this young guy. He was a real adventure the way he just confessed his secrets straight out like that. She didn't answer him, waiting to see how he'd play it. "Do you know about Professor Phare's pictures of you," he asked, "the ones on the internet?" Kate didn't answer. Her heart was pounding in her chest. "I didn't think so. Well, he has an account on some photo sharing website, and it's very public, and there's a very nice shot of you in a string bikini in Puerto Rico. The first time I saw it my head nearly exploded. I jerked off thinking of all the things I wanted to do with you, and I came so hard that my sperm ended up all over my laptop. I always knew you had a pretty decent body under those pantsuits, but I never dreamed you were that hot! It's like, I don't know, it's like you're the best one or something. You're the best one to mate with. You've got the ripest body I've ever seen, and you're the smartest woman I've ever met, and you'd make the best mom. And I guess when you come right down to it that's why I wanted to fuck you unprotected and cum inside you so badly, even though I don't want to have a baby at all. No way do I want that! It's all so fucked up. Does that make any sense at all?" "It does," Kate nodded, still working his shoulders, but more sensuously now. He was so candid about his desires and confusions, this guy, and Kate found it deeply attractive. "I think you've got some pretty good genes too, mister. And that's part of what makes me so hot for you, no doubt about it. I'm a primate after all, and there's no way a female can get close to male like you and not want to mix her DNA with you. It's just natural selection! But you can save the sweet talk, okay. I'm not letting you between my legs again tonight no matter how thick you lay it on. I'm not letting you fuck me again until we have some proper protection." Kate paused, wondering if Chad knew about the condoms, and whether he'd say anything about them. "Aww Kate, you're killing me," he drawled, "Why not? It was so amazing! And we still have a few nights before it gets dangerous." "No we don't silly," she chided him, slapping him on the back with her hands and digging her nails in deep. "It doesn't work like that. Women aren't alarm clocks. They don't always keep a regular schedule. And sperm can survive a long time inside a girl. Didn't anyone ever teach you that the rhythm method isn't safe?" "I know all that," Chad snapped back at her, groaning, as Kate's fingers dug into the soft flesh behind his shoulder blades. "It's not just about the timing. Women taste and smell different when they're ovulating, and their fluids feel different. More stretchy. That's why I went down on you last night. Partly anyway. I wanted to make sure it was safe. Believe me, you were definitely not ovulating. I'm like a wine connoisseur or something when it comes to fertile females! Your still a few days away for sure." Chad laughed out loud and Kate laughed with him. She loved the way he could poke fun at himself like that and be so open about his flaws and his kinks and his deepest desires. Was that a generational thing? Were all young guys like that now, she wondered, so up front about the fact that they didn't have it all figured out? Had Brian been like that once? She never knew him when he was a teenager. "Maybe so," Kate replied, "but I might be ovulating tonight." Chad turned around suddenly and faced her on his knees. He brought his hands to her waist and pulled her toward him a little, looking straight at her, holding her gaze. "Why don't we go in the tent and find out then, huh Kate?" he purred at her. "Why don't we go in the tent and get you out of those cute little shorts, and maybe that cute little sweatshirt too, and let me have a good taste of you. All over. I'll be able to tell." He leaned in to kiss her but and Kate was tempted but she pulled away at the last second. She brought her hands to his chest and pushed him away from her a little. "Uh uh, big guy. I'm not some bubble-headed undergrad. You are very talented with that mouth of yours and I know very well that if you get your face between my legs again you'll have your cock inside me in no time. You know that, too, naughty boy." She looked down at him and raked her fingers through his beard. Her nipples were plump and hard and poking through her sweatshirt and she realized she was sticking her breasts out for him without knowing it, even shaking them a little. It was insane the way her body responded to him like that. "If I let you go down on me you'll be screwing me senseless in no time, and we can't have that, can we big guy? We can't have you screwing me like a monkey all night and cumming inside me again when I could be ovulating tomorrow, or the next day, and your sperm would still be in my pussy, swimming around in there, when the egg dropped. We can't have that, can we?" She bent down and kissed him full on the mouth and he groaned out loud. She knew she was teasing him mercilessly but she didn't care. He deserved it after all the girls he'd taken advantage of, including her! He should have told her about the condoms. If he even knew about them. "A few days before I ovulate is definitely not safe for you to be cumming inside me with those big balls full of all those good genes," she murmured down to him, a little huskily. "But don't worry, I think I can make it up to you." She reached down for the bottom of his tank top. Chad smiled at her and raised his arms and she peeled it right off him. She could feel her lips moistening down below just from the sight of his naked shoulders and chest and stomach in the pale moonlight, and from that self-assured expression he always had when a woman broke down and made the first big move. "What would you do if you actually were pregnant?" he asked her, looking straight at her and leaning in and giving her a soft wet kiss, so delicate and sensual with his boyish lips. "What if I did knock you up last night? Would you keep it?" "I don't know," Kate answered without missing a beat, sticking her tongue out long and red and swirling it around his. She'd been thinking the same thing. "It's crazy for a girl like me to say this. I grew up in California for crying out loud. But I think I'd have it for sure. There wouldn't be any question really. It's the right time for me, and life has a funny way of deciding things for you. And it would be a very beautiful baby, and it would have great genes." Kate was kissing Chad on the neck and raking his abs with her nails while she purred to him about how hot it would feel to have his beautiful baby in her belly. She brought her hands to his chest and felt his heart pulsing hard against her palms. "Does that excite you" she whispered, "the idea of having your baby inside me? I thought you didn't want one? Is it making you very excited?" "Let's go in the tent and find out," he drawled at her, kissing her neck now and brushing his stubble against it. "Let's take my shorts off in the tent and I'll show you how excited it's making me." Kate was tempted again but she shook her head. "Stand up," she told him, "I want to take the shorts off out here." He stood up for her and she unbuckled his belt, and unbuttoned his shorts, and let them fall to his ankles so he could step right out of them. He wasn't wearing his boots. He was looking down at Kate while she gazed up at him dreamily, her hand rubbing his long cock through his boxers. She reached for the waistband and pulled them off in one motion, caressing his butt cheeks for a few seconds after the boxers dropped to his ankles and his cock sprang free, heavy and hard. Her breath caught in her throat a little when she saw it again. She loved the way it curved upward at the end, like it was engineered to be just the right length and angle to hit her sweet spot every time, and she loved how thick it looked with the network of blue veins spanning the whole width of it and bursting out through the delicate skin. She pinned his shaft back to his stomach and brought her nose to his scrotum, breathing in deeply and sighing. "Mmmmmmmm," she purred at him, looking up at him with her deep, brown eyes. "I sure do wish I could have this big boy inside me tonight. All night. But a few days before I ovulate is definitely not safe." She parted her lips a little and gave a wet soft kiss to the base of his shaft. "No way we can fuck tonight without some proper protection," she teased him, sticking her tongue out and licking the whole length of him, slowly, from base to bulb, and looking up at him the whole time, hungrily. "I sure wish we had something. Even a condom would do the trick," she pouted, swirling her tongue around the underside of his fat crown a little. "If we had a condom I'd let you carry me into the tent right now and fuck me every which way you wanted, believe me." She paused again, waiting for his next move. Maybe he didn't know about the condoms after all. She needed to tease him a little more and make sure. Then she could surprise with one later if she felt like it, which she probably would. She stood up and held him by the hand and walked slowly toward the tent, pulling him after her. Chad stopped and turned back for a minute so he could shut down the stove. He was always so careful with the details like that. She would have forgotten for sure. Kate smiled at him over her shoulder. She got down on her hands and knees and crawled through the entrance of the tent, swaying her ass a little as he came up behind her. When they were both inside she told him to lie on his back and keep still so she could explain the rules. "I'm keeping my clothes on, okay tiger? And you're keeping your hands to yourself. My trip my rules. Okay?" Chad nodded. "Good boy," Kate taunted him, lying down next to him in her sweatshirt and running shorts and kissing him on the lips. "Be a good boy just like that and you'll get lots of rewards." Chad nodded. "You have to lie still and keep your hands to yourself, okay stud? But I am not going to lie still and I am not going to keep my hands to myself. I'm going to put my hands all over you." Kate reached behind her for the tube of Vaseline in the sleeping bag and when she found it she opened it with her teeth, and spit the cap out, and squeezed it all over Chad's shaft and balls and started massaging him with her hand. "Awwww Kate," he groaned, "you're killing me like that!" Kate smiled inwardly and started massaging him harder. She made sure to coat his balls all over and his shaft and his crown too and then she made a ring with her finger and thumb and started tugging at the base of him, keeping her grip loose and taking it nice and slow, but pulling his foreskin up the whole length of him and then sliding it back down. Over and over and keeping a steady rhythm. "Ahhhh Kate. Oooooohhh Jesus. That is so hot!" "Yeah, you like it? You like the way my little hand looks wrapped around your fat cock like that? You like it when Professor jerks you off like that?" Chad nodded and stared down at his cock in her hand in rapt fascination. "Oh yeah? And do you like it when she jerks it with both hands like this?" Kate was straddling him on her knees now and reaching straight down and stroking him with both hands. She was holding her left hand around the base of him, and her right around the tip, and she was pulling up on him slow and steady and looking straight down at him with her brown eyes full of desire. She was rocking her pelvis and hips a little and reaching straight down with both hands and stroking him steady, a little harder now, and her eyes were half-lidded and a little dreamy looking. "You like it when Professor jerks you off with both of her hands and pictures how it would feel to have that monster inside me right now? How hard it would make me cum?" Chad groaned and nodded up at her and Kate smiled down at him wickedly. Advanced Primatology Ch. 10 "I bet you do. I bet you like it. But I bet you wish it was my pussy, don't you, instead of my hands. I bet you wish it was my pussy wrapped so tight around you and rubbing all over you?" Chad groaned and nodded. "I wish it was too, baby. And I'd slide it inside, too, just for a little while, if you weren't so leaky already. Just look at you!" She brought her pointer finger to the tip of his cock and dabbed it in the little pool of precum in his crown. She pulled her finger away and watched his sperm get long and stretchy. "You are full of sperm, big boy, and there's no way I can put that monster inside me without some real protection." She was bouncing up and down on her knees a little and jerking him a little harder and faster with both hands and her voice was getting breathier. "I'd be too afraid of getting pregnant if I had that big cock inside me. I'd be too afraid of getting carried away and letting you fill me up again, but with a big baby this time, with a big baby inside your Professor's belly." "Awww Kate." "I'd be too afraid of getting carried away and saying dirty things to you and making you crazy to fill me up. Would you like that?" "Awwww Kate." She was bouncing up and down on her knees and gasping out for him and jerking him hard and fast with both hands and her breasts were bouncing so hard in her little sweatshirt it was falling off her shoulders. "You want to fuck me, tiger?" Chad nodded and groaned. "You want to fuck me raw with your big cock and make me cum with it and make me scream out your name?" "Aaaahhhh Jesus." "Fuck me, Chad. Fuck me senseless. Fuck me hard with your big cock and fill me up with your big balls." "Aaaaahhhhh Christ." "Fill me up with your big cock, baby. Fill me up with it, okay stud? Fuck me wide open with your cock and give me your hot cum inside me and give me a beautiful baby because I'm cumming so hard on your cock and it feels so beautiful inside me!" Kate was bouncing like a woman possessed and her sweatshirt was falling off and you could see the tops of her breasts bouncing hard. She was pulling Chad's foreskin so hard she thought she might injure him or something and he was groaning out loud with his eyes closed and his stomach clenched all the way. And when she looked down she saw the first jet of hot seed spray right out of him and arc through the air and land hard and loud with a big splat in pearly drops all over his chest and abs. She was jerking him slow and steady now, being more careful now that he was cumming hard and his crown was more sensitive, and he was spraying out jet after jet as she kept right on striking him. He was covering himself all over with pearly drops and Kate was laughing out loud. "That's it, baby. Give me all of that beautiful seed. I want it baby." "Oooohh Jesus. Fuck." He kept pulsing and spraying and jet after jet was arcing through the air and it looked so filthy to have his cock in her hands and her sweatshirt falling off her. She could see Chad's heart beating through his rib cage while the little pools of seed trembled all over his body and his stomach heaved. He was so full of cum and he was still spraying it all over himself and Kate smiled wickedly and brought her lips to his balls and sucked them inside her warm mouth, one after the other, while she gave his shaft a few last tugs for good measure and watched it still spurting hard even though his balls were empty. "Poor baby. Are you all tapped out now? Don't hurt yourself cumming so hard for me while Professor jerks you off." "Oooohh my fucking god that is so fucking hot. Oooohh my god what did you do to me?" Kate straddled Chad on her knees again and looked down at him, so pleased with herself. He looked so beautiful in the moonlight covered in sperm like that and before she knew what she was doing Kate was pulling her sweatshirt off, and laying on top of him, and covering him with her whole body. Her breasts were swirling against him and sliding over him and they were both covered with his seed. They were kissing each other and swirling their tongues together and laughing in each other's mouths. They made out like that for a few minutes and then she felt him drifting off to sleep. She rolled off him and he felt her move and he searched for her with his hand and then spooned up behind her. It felt safe and comfortable with him all naked and spent like that and with her still in her running shorts. It felt nice and intimate falling asleep in his arms like that with her breasts in his hand feeling all cool and fragrant with his sperm. She was going to let him sleep for a while, and then she was going to wake up and ask him about the condoms, and show them to him, while he was still groggy and unguarded. She was going to ask him for the truth, and it didn't really matter what he said to her as long as it was honest. She was pretty sure he didn't know about them because there was no way he could have held out while he teased her like that. There was no way he wouldn't have broken down and told her about them so he could fuck her. She felt a little bad about torturing him so badly. But the funny thing was she wouldn't even care if he did know about the condoms the whole time. She would care at all as long as he was honest with her about it. She'd had enough lies to last a lifetime. He could tell her that he knew about them and he kept it secret because he wanted to fuck her unprotected so badly. He could tell her that. She wouldn't hold it against him. It wouldn't keep her from sliding one of those condoms right on him, and getting on her knees in front of him, and sticking her backside high in the air for him so he could fuck her just like she loved it. She was going to sleep for a little while and then she was going to wake him up and ask him for the truth, and if he gave it to her she was going to give him her body in return. She was going to fuck him into sheer ecstasy. Advanced Primatology Ch. 11 Part 1 Kate woke up to the sound of rain pelting the roof of the tent. Chad was curled on his side with his knees drawn toward him and his head resting on her breast, snoring deeply. She'd been having the strangest dream! She held Chad a little tighter to her and stroked his back gently with the tips of her fingers, trying to relax and remember. Her heart was still racing! She shuddered a little as the details returned to her. They were back at the hotel in Dar es Salaam and she was on all fours in front of the sliding glass doors with the ocean and the stars spread out in front of her and Chad behind her thrusting. Her breasts were hanging down below her and swaying and she was rocking backwards to meet his thrusts. Her backside was slapping hard against his pelvis and she was grunting and gasping and calling out his name. "Ohhh god . . . ooohhhh Chad." The surf was breaking gently in front of her, white and foaming, and the stars were blazing and her whole body was pulsing and glowing. She was reaching for him with her tail and trying to hold him in deeper and give her a better angle. "Awwww Kate . . . awwww Jesus." He was all the way inside her and his cock was thicker and longer than she'd ever felt it. She had her eyes closed so she could concentrate. It was like nothing she'd felt before. It was almost like she was kissing and licking and sucking him with her sex and holding him just where she wanted him. White waves were breaking all through her body and she could feel little pricks of starlight burning her skin all over. He was massaging her cervix and she was coating him with her oils and pretty soon she felt his hot cum bathing her insides. "Awww Kate . . . Awww Jesus." She looked up and saw a dark round disk hanging low in the sky and she knew it was the dark moon, the new moon, and Chad was filling her with his seed. She was so excited! She tried to sing for him again but this time it came out different and strange: "Hooot hooot hooot hoooooooooot" Kate looked down and saw that her arms and hands were covered with thick, dark fur. She woke up in the tent with her heart pounding. What was that all about, she wondered, as she turned on her side toward Chad and tried to cuddle up in his heat. She wanted to be close to him, to be held by him, but his knees kept getting in the way. She pushed him over onto his back gently, careful not to wake him. The sun was just over the horizon by now and the rain had paused and Kate's heart skipped a beat when she saw him stretched out on his back, stark naked, bathed in pale light. He was a very beautiful guy, and she cared about him deeply. She cared about him in a different way than she'd ever cared about a guy before. She couldn't figure it out. On the one hand she felt responsible for him, like she wanted to take care of him and maybe even help him grow up a little, and on the other she felt this raw sense of reckless lust, like she wanted to screw him exactly how she wanted for exactly as long as she wanted and screw the consequences for either of them. She wanted to climb on top of him right now, in fact, and she thought about it for a minute, trying to remember where she hid the condoms last night. He was semi-hard already and when she reached her hand down she couldn't believe how wet she was. She wondered if it was just her imagination or if her fluids felt thinner and more slippery this morning. It was messed up but it made sense when you really thought about it. Just because she was divorcing Brian didn't mean that she'd suddenly stopped wanting to have a baby. She wanted one very badly! She couldn't turn her desires on and off like that, with a switch or something! And she was alone in the mountains with a very attractive mate who she cared about sincerely, and who she loved having sex with, and who was obviously very fertile. He was a very good candidate to give her what she wanted most in life right now, at least part of her: a big belly, round and full, and then a healthy baby with lots of successful genes. That's why her body responded so powerfully to his signals! The way he smelled, and moved, and the sparkle in his eye when he put her on her back and took her that first night in the tent. Kate was on her back now with her hand still between her legs. Maybe her fluids did feel more slippery. She held her fingers to her nose to see if she smelled different too. But she was so unfamiliar with her own scent, really, that there was no way of telling. She couldn't be sure but she thought she was maybe a little saltier and sharper. It was almost the new moon, after all, and she might be ovulating a little early. That would definitely help explain how horny she was feeling! She wanted to wake Chad up right that second and have hot sex with him before the workday started. She was all set to roll over on top of him when she remembered the condoms. She didn't feel like talking about all that complicated stuff right now: asking him whether he knew about them and kept it secret the first night when they had unprotected sex and he came inside her twice. What did it matter anyway? They barely knew each other a few nights ago. What did it matter if he lied? She thought about waking him up again but he looked so peaceful sleeping there, like a child almost. They were both tired and could use a little extra rest. They had a long day ahead of them. She couldn't wait to get to the cloud forest and find the chimps again! She was feeling so confident and excited about her research. She knew with a dead certainty that it was all going to work out perfectly! She was going to prove her hypothesis about Brad and Mahalia with evidence that no one could refute, and she was going to write it up in an argument that was so persuasive and logical that no one could deny it, including Brian, and it was going to knock everyone on their asses! She was going to get tenure, and buy her own house, and have a bigger lab with a bigger budget, and then . . . Kate stopped herself, stunned by the strangeness of the thought. And then . . . she was going to have a baby. She couldn't understand how automatically it had come to her as the next item on the list, like it was inevitable. But why should that be strange? It was the most natural thing in the world for a woman her age, a woman at her peak. She would be an amazing mother! Anyone could see that. She could do it all by herself if she wanted to. She almost laughed out loud as soon as she thought it consciously. Maybe she should kill two birds with one stone up here in the cloud forest. Maybe she should use the long, hard days to collect all of the data and evidence she needed to get to the next level in her career, and maybe at night she and Chad should eat and talk and relax together and have sex in the tent, and maybe, just maybe they should make a baby together too. She couldn't believe she was even thinking about it! It was too crazy, even if it was just an idle fantasy. Or maybe it was better that way. Maybe it was better to think it consciously, and fantasize about it too, instead of pretending she wasn't feeling it. That way they wouldn't get surprised and carried away by their desires. She couldn't wait for her work in the field today and she couldn't wait for after dinner tonight. She was going to ask Chad about the condoms, and she was going to tell him about her dreams in vivid detail, and there were going to be fewer condoms in the morning for sure. Kate's hand was between her legs and she was fingering herself absently as she remembered another dream, from earlier in the night. They were in the hotel bed and the mattress and the sheets felt cool and plush against her back and Chad's cock felt incredible all naked and fat inside her. He was looking down at her and his blue eyes were pleading and she was nodding up at him and pulling her knees toward her chest and tilting her uterus up toward him. Part 2 "Ahhhhhhhhhhh," Brian groaned out loud. "There's nothing like some twenty-year-old pussy and a good hard fuck first thing in the morning," he thought to himself, looking down at Elise. She was curled up in a ball on the mattress with her knees to her chest and her snatch tilted up to him so he could plunge his whole length straight down inside her. Jesus this little stuck up preppy girl knows how to fuck a man right, Brian marveled, not for the first time. She was a real blast, in fact. She was just the thing to take his mind off Kate and the collapse of his marriage. She was gasping and grunting every time his balls slapped her ass and her blonde hair was spread wide on the white sheets. Her pale skin was flushed deep red and covered with a thin sheen of sweat. They were both on the edge. "You like fucking my pussy?" she asked him, rolling back on her shoulders and spreading her legs a little wider. "You like fucking my pussy with your big professor cock?" "Ahhhhhhhhh" Brian gasped out in pleasure, nodding down at her smugly. "I bet you do, you dirty old bastard," she teased him, her smallish breasts shaking and jiggling as he picked up the pace. "I bet you like fucking my tight young pussy." "Ohhhhhh fuck," he cried as she wrapped her legs around him tight and pulled him deep inside. "And I bet you liked fucking Pamela with that big cock last night too," she chided him, "I bet you liked it a lot. Be a good professor for me this morning and I'll make sure you get some fresh pussy tonight. Okay? Be a good professor and fuck me hard and I'll get you any girl you want." "Ohhhh fuck me," he groaned, lost in his pleasure. "Maybe you can fuck Ellen," she purred to him, raking his back with her nails and squeezing her legs together hard. "She's pretty serious about that girlfriend but I bet we can get her hot enough to cheat. Would you like that?" Brian nodded down at her, sweat dripping from his forehead and all over her chest. Her nipples were long and stiff and he bent down to taste them, savoring their salty plumpness. "Or maybe you can fuck Alex," she teased him mercilessly, her pale blue eyes glinting. "I saw you looking at her plump little British ass in her bathing suit yesterday and I know you liked it. I know you like the married ones. I know you like it when they spread their legs for you so you can make them cum over and over with your big famous professor cock." Brian was fucking her wildly now, pulling all the way out and then plunging straight down in. "Did you know that Roger is going away tonight? Did you know he's going to the village for supplies and he won't be back until the morning? Maybe I can convince her to go snorkeling with us today. Maybe she'll wear a bikini this time. Maybe I can talk her into partying with us tonight and we can get her drunk and high and have some fun together. Would you like that?" "Ohhhhhh fuck . . . Ohhhhh yes." "Ohhhhh Brian," Elise gasped for him, doing her best imitation of a posh British accent. "Ohhhh Brian . . . Ohhh fuck me . . . Oh fuck me hard with your big fat American cock and make me cum with it." "Ahhhhhhhhhhhhhhhhhh," he groaned long and loud as his balls contracted and emptied inside her. He collapsed on top of her, both of them still breathing hard and laughing. Elise was a real blast, for sure, but he could never be serious about her. She was just what he needed to help him get over Kate but she was all wrong for him in the long run. No, what he needed eventually was someone older, and a little less wild, and a little more like Kate. It was a shame she couldn't handle his cheating in the end because other than that she was perfect. Yes, he needed someone pretty much exactly like Kate, but a little more yielding, more feminine even, and maybe a little younger too. Part 3 Karin stretched herself out in her sleeping bag listening to the birds sing in the canopy above the tent and remembering her conversation with Courtney from the night before. They were good friends by now and she felt comfortable opening up with her. She was surprised at first when Courtney came right out with it asked her why she'd cheated on her fiancé with Chad. But it felt good in the end to talk about it. She told her all about her "bucket list" with her fiancé Rick and how Chad had been the only real guy on it. Courtney wanted to know why. She wanted to know what it was about Chad that made him so irresistible to girls. Was it really just the alpha male thing? Was it really just the broad shoulders, and the square jaw, and the ripped stomach, and the big cock. She wanted to know about his big cock in particular. She wanted to know how it made her feel. Courtney was just like a guy, Karin laughed to herself. Rick wanted to know all about Chad's big cock too. One time when they were having sex and he was asking about him again Karin mentioned what she'd overheard in lab that day. It was the end of a long session and Elise and her friends seemed to have forgotten that she was there. She overheard them talking about Chad and about how he'd slept with one of Elise's sorority sisters that weekend. She said he was hung like a porn star! Karin had never seen Rick so excited as when she told him! His face was bright red and she could see the veins popping out on the sides of his head. He was thrusting into her like a maniac and she thought he was going to pass out from the rush of blood to his brain. Why did he find it so thrilling? And why did she find it so thrilling too? She tried to pretend otherwise with Courtney, but neither of them was convinced. She tried to tell her that it was no big deal, that it was even kind of tiresome, like you were obligated to act amazed by it, and worship it, and tell him about it all the time. But in the end there was no denying that Chad had rocked her world with that big cock of his. Sure, part of it was just the excitement of being penetrated by someone other than her fiancé, and with his permission, sort of. And part of it was the fact that Chad was very sexy, and he'd been with lots of women, and he'd mastered the fine art of thrusting, among other things. But part of it was definitely the raw surprise and rush of being filled up so completely and fucked so very, very hard. She'd never cum so hard in her life! She wondered how her fiancé would take the news when she got home and told him the details. If history were any guide it would probably drive him mad with lust! They would probably get off to it for months, hell, for years, for the rest of their lives together maybe! The only time she'd seen him more excited was when she told him about catching Brian and Elise having sex on the desk in his office. She opened the door without knocking and she was too shocked to move and they didn't notice her standing there watching. Elise was bent over the desk. Brian was pounding her from behind and on the out strokes Karin could see his whole length and girth. It was the biggest cock she'd ever seen in person. Rick was beyond excited! He wanted to know if she liked looking at it, even just a little, in a twisted way. He wanted to know if it turned her on, maybe just a little bit. He wanted to know if she wished it were her bent over the desk being taken by her powerful boss, the one who could make her a star in her field if he wanted to, if she made him want to. Later that night, as they were drifting off to sleep, he asked her if she wanted to put Brian on her bucket list too, because that would be okay with him as long as she was very discrete. Karin punched him hard in the chest and told him that the whole idea repulsed her. He was her boss and he was maybe fifteen years older than her! But it didn't repulse her. She'd thought about it lots of times in the weeks since, and she'd given herself some very hard orgasms. Part 4 It had been a hard day in the field and Kate was famished by the time she and Chad stopped for lunch. They'd skipped breakfast that morning, munching on some nutrition bars while they hiked down into the cloud forest to find Brad and Mahalia's nest. She wanted to locate them early before they wandered off in search of food and water. The found the chimps at the base of the same tree where they left them yesterday. Then they spent the whole morning making observations and collecting samples. Kate took lots of photographs and videos of Mahalia that she was planning to analyze later. She wanted to see if they held any clues about her mood and stress levels. Female chimps were a puzzle alright, especially the older experienced ones. She spent hours staring into Mahalia's round dark eyes trying to sense what she was thinking and feeling but still she couldn't be sure. Absorbed in her work, she forgot to remind Chad to collect the urine samples that she would use to check hormone levels back in the lab at UNC. So when she looked up at one point and saw him placing two test tubes into the cooler beside her she was beyond delighted. She felt like running her fingers through his beard and kissing him. He smiled at her and held another test tube up close to her in the sunlight so she could see what was inside. "Some of Brad's hair. I found it on the tree trunk over there after he was scratching his back against it. We'll need it to check paternity, right? For his DNA? They sure have been busy this morning!" Kate dropped her head and laughed. They sure had been! They'd copulated four times already and it was only 2pm. Each time had been quick and anxious. Kate could sense they were still on the alert for an ambush by the jealous males of M group. But she managed to gets lots of good footage that she could study carefully later. What she wanted to know more than anything was if Mahalia was actually having orgasms when Brad penetrated her from behind, so quickly and crude like that. She wanted to know if it got her off. That would help explain why she had chosen Brad for an exclusive safari, and it would help flesh out her theory about the role of female orgasms in determining which males passed on their genes. She was always surprised by the abruptness and clumsiness of chimp sex. It was nothing at all like with bonobos—those long, languid sessions full of foreplay and obvious climaxes for the males and females. The high-status females would sometimes close their eyes and roll their heads back and shudder long and slow for three to four seconds. With chimps it was never like that. But Mahalia seemed to be enjoying herself all the same, in her own inscrutable way. Kate looked over at Chad and saw that he was handing her a bowl filled with bits of jerky in a mound of leftover rice. It smelled wonderful. He was wearing his Carolina blue tank top with a soccer ball logo. She savored the look of his brown arms and chest and neck. His beard was growing in nicely—thicker and darker and wilder. "So how old are you anyway?" she asked him. Chad looked up at her from his bowl, a little uncertainly. "I'll be twenty-one in July," he answered, nodding at her, almost proudly. "Don't say it that way," Kate laughed at him. "What way?" "Like a kid, silly. You sound like a little boy bragging that he's nine and three-quarters." "Okay," Chad agreed, turning bright red. "How should I say it?" "Just say you're twenty." "Okay. I'm twenty." "Good boy." She reached her hand out and stroked his beard under his chin. They gazed at each other for a few second and then they both fell silent, devouring the rice with their fingers. After a while she looked up at him again. "So, you got any plans for the big day?" she asked. "What day?" "Your twenty first birthday, silly. Are you and the other soccer players going to throw a wild party, somewhere off campus maybe? With lots of beautiful co-eds?" "I don't know," Chad muttered, looking upset all of a sudden. Kate expected him to react to the part about the beautiful co-eds, to flirt with her about it maybe, but he went in another direction entirely. "I'm supposed to go back home and stay with my mom for July, actually, but I'm kind of dreading it. I wish I could stay in Chapel Hill instead." Advanced Primatology Ch. 11 "How come?" "I don't know," he sighed. "I guess it was just really hard the last time I went home. She was feeling fragile. Her sister had just moved out west for a new job, and, well, my mom relies on her a lot. She was worried she might have a relapse or something. She barely let me out of her sight for five minutes the whole time I was visiting. Three weeks. Coming back to school was awful. She begged me to stay. She said she didn't think she could stay clean without me there and she begged me to take a leave of absence from school so I could take care of her for a few months until she felt more stable. But there was no way I could do that! I was pissed at her for even asking, actually. She knows how much school means to me, and soccer and everything. That's just how she is though. She's like a vampire when she gets all needy like that. She sucks the life right out of me. I feel like I can't go back there anymore. Not for a while anyway. I feel like I can't even set foot in her apartment. It's like every time I walk through the front door, I feel . . ." "Like you're going to throw up," Kate interrupted him. She was hanging on every word. "I understand completely. That's just how I used to feel when I came home from college. The tension between my mom and dad was unbearable and it made me feel nauseous all the time. I stopped going home for summers after my freshman year." "What did you do?" "The first summer I worked in one of my professor's labs. That was the summer I hooked up with Brian. The next few summers I shacked up with him in his apartment in Oakland. Then we got married." Chad looked at her thoughtfully. "Is it true he was your TA? Sorry, I shouldn't have asked that. It's just that Kevin told me a rumor about it." "It's okay. Yes, he was my TA." She thought for a second then smiled at him wickedly, "Why do you want to know?" Chad shrugged, a little sparkle in his deep blue eyes. Kate narrowed her eyes and pouted and pressed her breasts together with her arms. She was wearing her loose white button-down as usual but you could still make out her shape and heft. "He was my TA, and I was his hot, naïve, barely legal undergrad and he charmed my pants off and fucked me hard on the first date! Happy now?" Chad laughed at her and swallowed his rice. They both fell silent again. "So why can't you stay in Chapel Hill?" she asked him after they ate for a few minutes more, listening to the wind through the high canopy. There was a storm coming tonight for sure. "Is it that you feel too guilty about abandoning your mom?" Chad shook his head vigorously. "No. I don't, actually. But the athletics dorm is closed for July for renovations. And anyway, we're supposed to go home for the month and then report back in August for pre-season practice." "Can't you stay with friends, or rent your own place?" "A couple friends told me I can crash on their floor, but that seems kind of stressful. I need to chill out and read and stuff before the semester starts, and training. Maybe do a little yoga!" he winked at her when he added the last bit. "I'd love to get my own place, but I can't afford it." "Why don't you get a summer job then?" "Like what?" "I don't know. Wait tables or something. You're a strong handsome young guy with a nice smile. Restaurants will be lining up to hire you." "Thanks," Chad laughed, "maybe I will." Kate chewed her rice and look at him, appraising him. She liked giving him advice like this. Helping him on his way. He was so hungry for that kind of thing, and he took advice so gracefully and with such obvious happiness. He'd been hungry all his life for the guidance and affection of an older woman, the real affection of a woman who wasn't dependent on him for anything, and it was easy for her to give him that. It came so naturally to her, and it give her pleasure too. "I've got a better idea, actually," she added, kind of thinking out loud. "Maybe I could pay you to work in my lab for the month. You could help analyze the samples from Brad and Mahalia." "Really?" Chad blurted, almost dropping his bowl. "That would be awesome! How much could you pay?" Kate regretted the proposal almost as soon as she voiced it. She hadn't thought it through carefully enough before getting his hopes up. She made a note to herself to be more careful in the future. "I'm not sure, sweetie. I'd have to go over my research budget. I'm a little tapped out from this trip. I'm not sure I could pay enough to cover your rent and expenses. But I'll try to work it out." Chad shrugged at her, looking down, clearly disappointed. "That's okay. Whatever. It would be cool if it worked out though." Kate frowned inwardly, upset with herself for her rashness. She watched him chew his rice slowly. She was surprised by how easily she could hurt him, and she couldn't stand the feeling, and before she knew it she was being rash again. "Maybe you could stay with me . . ." Chad jerked his head up and swallowed hard, looking right at her with wide eyes. Kate cursed herself inwardly again. Now she'd really done it! He looked so surprised and grateful and vulnerable and there was no way she could rescind the offer without really hurting him. She considered her options, taking another mouthful of rice and chewing it carefully to buy time. "I've been thinking about it and my plan is to stay in the house for the rest of the summer while Brian's finishing his lecture tour. I'll get a condo near campus once the semester starts but I want to finish my research first. There's a guesthouse out by the pool. You can stay there." "Really?" Chad answered, still guarding himself a little. "Uh, won't that be kind of awkward? I mean, Brian will find out we're sleeping together, right? Aren't you worried you'll get in trouble if I'm staying at your place and word gets around?" Kate shook her head. "Brian won't say anything. Besides, students stay in that guesthouse all the time. We've had lots of research assistants live there for a month or two during the summers. It won't be a problem." Chad nodded and looked down again, pleased, but a little flustered all the same. Kate knew what he was thinking. "Are you wondering if you'll still get to have sex with me?" Chad grinned at her slyly. "We'll have to be careful, but, yeah, I think we can figure it out. Maybe I'll sneak over to the guesthouse at night, every once in a while. Or maybe we'll find a place at the lab for quickies." He made big excited eyes at her, "hoot hooot hooooot." She dropped her head and laughed, turning bright red. "Come on. Let's get the packs ready and get back to work. Brad and Mahalia will wake up from their siesta soon and they'll probably get busy right away. I want to be there to film it." She stood up and turned her back to Chad and bent over to start packing. She was thinking about the chimps already, lost in her thoughts. She didn't notice him slipping up behind her until she felt his hands easing her yoga pants off her hips and his groin pressing against her. He was rock hard! "I could really get used to this 20-year old thing," Kate laughed to herself, reaching back to push him away. "Awww Kate," Chad drawled, "you sure we don't have time for a quick hot one? Like the chimps do it?" Kate stood up and turned around and pushed him hard in the chest with both hands, still laughing. "No, you big ape! We don't have time. And anyway, we don't have any protection." She paused for a beat, eyeing him. "Or do we?" She was looking straight at him with her arms folded and she wasn't smiling any more. There was no mistaking her meaning. Chad looked down and kicked the soil a little with the toe of his boot. She'd caught him off guard and he didn't know how to play it. He looked up at her and took a deep breath. "Actually, we do," he said nervously, his voice a little higher than normal. "There's a four pack of condoms in the first aid kit." Kate nodded. "I know. I found them yesterday before dinner. Did you know about them the first night?" Chad nodded. "Yeah, I packed them. I knew about them." "And you decided not to tell me?" He nodded again. "Why?" Chad shrugged. He was pleading at her with his blue eyes, begging her to let him off the hook, but Kate stood her ground. "Well?" "I'm sorry, Kate. I should have told you. I don't know why I didn't. I guess I wanted to see if you'd be with me without protection. If you were that attracted to me. If you thought I belonged inside you. I'm really sorry. I shouldn't have lied. I shouldn't have deceived you like that. You've been amazing to me, a real friend, and I shouldn't have done that." It was unlike any apology that Kate had ever received from a man and it knocked her completely off balance. She was deeply moved by it—by how naturally the right words came to his lips, and how sincere they were, and by how he knew intuitively how much he could have damaged her trust. She was looking straight back at him and her heart was thumping and her brown eyes were glistening. It was partly because she felt so gratified by the apology, like it was the one she'd been waiting for her entire life without knowing it. But it was also because she felt something deeper and stranger at the same time, something totally unexpected. She felt proud of Chad. She felt like he was really growing up by working with her, and by being in a relationship with her, and she felt proud of her role in that. She smiled at him warmly and thought carefully before she spoke. "It's okay. I forgive you. This time." She pulled her pack onto her shoulders and turned away from him to find Brad and Mahalia. They were somewhere out there in the dense forest, behind the curtain of mist that was beginning to pour off the foliage. The storm was approaching and they needed to work fast. Part 5 Brian woke up from his nap and tried to remember where he was. He had a belly full of beer and cold spare ribs and his head was foggy. He heard female voices whispering and laughing nearby and when he looked up he saw Elise and Pamela and Alex lying on their backs in their bikinis and talking about something—girl stuff most likely. Now he remembered. He'd taken them back to the snorkeling spot in the boat for another long, lazy day of sun and fun. They didn't know he was awake yet and he took advantage of the fact to steal a long, careful look at Alex's body in the plaid bikini. She was pale and ruddy with little freckles all over and just the right amount of flesh on her belly and sides to give her that matronly, housewife look that he always found so intensely alluring. He couldn't really tell what shape her tits were in the modest top but he could tell they were soft and substantial. He watched Elise roll over on her side and whisper something into Alex's ear and then he watched Alex turn bright red and laugh, almost girlishly. She turned her head to the side, toward where he was lying, and took a long, lingering look at his package in the snug shorts he was wearing. She let her eyes travel up the length of his body, taking in his beefy frame, still fit and trim for a middle-aged man. He closed his eyes so she wouldn't notice he was awake. He didn't want to ruin the moment. He wanted to let her look at him as long as she wanted. They had a long afternoon and a long evening ahead of them and things were beginning to get very interesting. Part 6 The sky opened up before Kate and Chad were back to the campsite. By the time they reached the tent they were both drenched to the skin. They'd worked as late as they could, collecting lots of samples and watching Brad and Mahalia copulate three more times, grooming each other between sessions. Then they packed hurriedly, both of them realizing too late that they wouldn't be able to keep ahead of the storm. They could see the dark clouds rolling in behind them as they made their way home and just as the campsite came into view the clouds caught up to them and the rain started pouring down in sheets. Chad was surprised by how quickly the temperature had dropped (it was easy to forget how high in the mountains they were) and by how chilled he was when he finally unzipped the entrance of the tent so they could hurry inside. He found the two big beach towels where he'd left them to keep them dry and threw one of them around Kate's shoulders. Her teeth were chattering. Then he stripped naked as fast as he could, Kate watching him the whole time, and toweled himself off, slipping on a pair of boxers when he was good and dry. Once they'd warmed up the tent with their body heat Kate slipped the towel from her shoulders and started to take off her wet clothes too—unbuttoning her white shirt slowly and sliding it off, then pulling off the sport bikini top she'd been wearing underneath it. Chad's eyes went wide as her breasts bounced into view, still wet and glistening. Jesus she had an incredible body. Was it his imagination or was it even more incredible today? Her breasts looked rounder and fuller and higher on her chest than they normally did and somehow more symmetrical too. And her lips looked plumper and fuller. Her whole body looked . . . riper. That was the word for it. He watched her raise her butt off the sleeping bag to slide off her wet yoga pants. Her breathed in deeply through his nose as her dark curls came into view and she spread her legs apart a little to dry the insides of her thighs. Jesus she smelled strong. She smelled unbelievably sexy. "Gosh, you big ape! Give a girl a little privacy will you," Kate teased, realizing that he'd been ogling her the whole time. Her voice sounded higher than normal, more musical and enticing. Chad slid over toward her and kissed her full on the lips, drinking in the scent of her breath. He brought his hands to her breasts so he could weigh them and bounce them in his palms. Kate slapped them away. "Easy, tiger. I'm hungry. Let's eat." She turned her back to him and slid on her sweatshirt and her running shorts while Chad tried to figure out what they could have for dinner. Part 7 Kevin needed to make a move on Jess soon or he was going to end up in the friend zone for sure. They had so much in common, and they were having a lot of fun working together and hanging out at night, but the more comfortable they became with each the more he could feel the sexual tension waning. He dropped two bags of rice into the pot of water boiling on the stove and watched her carefully. She was sitting with her back against a tree trunk reading her field notes and watching some dark storm clouds roll in over the mountain ridge to the west of them. It was a big storm by the looks of it and Kevin was glad that it would miss them. It seemed like Jess had a kink between her shoulders or something, probably from carrying a heavy pack all day long and sleeping on the hard ground all night. She kept rolling her head around and reaching back with her hand to massage the spot where her neck met her spine. Kevin took a deep breath in and held it. Now or never, bro, he told himself. "Why don't you come over here and I'll work that kink out for you while the rice cooks." Jess looked up from her notebook, eyeing him curiously. She was wearing her snug Rutgers t-shirt and her tiny running shorts as usual. "Are you sure you know what you're doing?" she asked him, teasingly. "I don't want some inexperienced undergrad giving me some lame massage and making my back feel more sore than it already does." "Hey, I'm a bass player!" Kevin shot back, playing hurt and insulted. "They'd take away my license if I didn't know how to give a lady a decent massage. Plus, I took an exercise science course back in freshmen year." Jess laughed, still eyeing him, not sure how to play it. "Okay. Let's see what you got." She stood up and walked over to him. Five minutes later and Kevin could feel her neck and shoulders relaxing in his hands. He was seriously in love. Jess was his ideal woman, and he could swear she was flirting with him a little. The water was boiling and he needed to keep his focus because his head was swimming and he didn't want to blow his chance. "That feels nice," she purred, arching her shoulders and letting her chest jut forward. He was taller than her so even sitting behind her he could still see her shape. Part 8 The rain was torrential by the time Kate and Chad finished their makeshift dinner—just some jerky and dried figs and balls of leftover oatmeal that Chad threw together quickly, arranging them in the metal bowls with a kind of rough elegance. He always came through in a pinch, Kate thought. She was glad that he rigged up the heavy tarp over the tent that morning for added protection from the coming storm. The sound of the rain against the tarp was deafening but they were safe and warm inside the tent. They sat cross-legged facing each other with their empty bowls in their laps. Chad was still shirtless, wearing nothing but his tight black boxers. Kate watched the little beads of perspiration breaking out on his bronze chest and running down him in rivulets, all over his stomach and sides. It was like a steam bath inside the tent by now and Kate felt drowsy and full. "It's hot in here, don't you think?" she asked him, fanning her face with her hand. "Guys are so lucky." "Why's that?" "Because they can always go shirtless if they want to. They don't have to cover up their curvy parts." "You can go shirtless too. You don't have to cover up for me." "Yeah, I bet I don't," she shot back, rolling her eyes. "Not just yet, though. I want to talk about the chimps first and I don't you to be all distracted. We've still got work to do." "I won't be distracted," he smiled at her. "I promise. Come on. It feels nice without a shirt. It's kind of like a spa in here. Enjoy yourself a little." Kate thought for a second. It made sense when he put it that way! She reached for the bottom of her sweatshirt and pulled it over her head in one fluid motion, folding it carefully and laying it down beside her. She wondered if it was just a trick of the light in the tent (Chad had improvised a lantern by wrapping one of his grey t-shirts around the LED headlamp) or if her breasts looked especially perky and round this evening. Her right breast was normally a little lower than her left but tonight they were both riding high on her chest. They seemed perfectly symmetrical. They were covered all over with a sheen of sweat and they were glistening in the dull glow of the headlamp. She looked over to Chad and blushed deep crimson when she saw how much he was enjoying the view. "You promised not to be distracted, you big troglodyte!" "Sorry," he laughed, blushing deep red himself. "You've got to cut a guy some slack when you've got a pair of tits like that!" "Easy now," she teased him, pleased with the compliment. She felt so comfortable with him tonight, and so confident with her body. She liked it when he got a little edgy with her, talking about her "tits" like that! "So what did you want to talk about?" he asked her, still sitting cross-legged and looking right in her eyes. "About Mahalia," she responded. "What about her?" "I'm trying to figure out if she's enjoying herself when she copulates with Brad. I know that she enjoys all the grooming and feeding and stuff, and I'm pretty sure that her stress-levels are very low. But what I really want to know is if she has orgasms when Brad mounts her." "How come?" "Because I want to know whether that's part of the reason that she went on safari with him. I want to know if she came up here partly for the orgasms. It would be amazing if I could prove that! It would knock every primatologist in the world right on their ass if I could prove that mature females like Mahalia reproduce with young males like Brad because they give them a better chance of having orgasms." Advanced Primatology Ch. 11 "Why's that?" "Because primatologists have always been mystified by female orgasms! They can't figure out what the purpose of them is, in evolutionary terms anyway. The female doesn't have to have one! She can still get pregnant. So what are they for? Typical guys!" "Hey, take it easy," Chad teased, pretending to be insulted. "I have all the respect and appreciation in the world for female orgasms!" Kate laughed, blushing again. He wasn't kidding! He had clearly spent a lot of time in his life learning how to get a girl off! "It would make perfect sense if she picked Brad because she thought he'd give her better climaxes," she continued. "The whole arrangement would make sense. She picked a male who groomed her and fed her for weeks and weeks before she came into estrus. So she was confident that he would do all the work for her once they got to the cloud forest. And she probably knows that if she's rested and relaxed she has a better chance of actually enjoying the sex!" "Totally," Chad interjected, full of enthusiasm now. "And remember how carefully she inspected his penis and testicles? She's a very experienced female and she probably knows which kind give her the most pleasure." "Good point!" Kate encouraged him. "I forgot about that! She definitely liked what she saw when she inspected his penis or she wouldn't have come all the way up here alone with him. That was a risky move for her!" "Yeah," he agreed. "But I think she's glad she did it. Think about it! It's all relative from her perspective. If she was back with M group she'd be copulating dozens of times a day with males who were challenging each other and fighting over her constantly. She'd be exhausted and stressed out. It's way more mellow with Brad, even if she's not getting off." "But I want to know if she IS getting off," Kate shot back, waving her hands in frustration and blushing when she noticed that her breasts were jiggling. Chad was eyeing them hungrily. "I think she is," Chad asserted confidently, trying to maintain his focus. "Where's the video camera? I'll show you." Kate turned from him and fumbled through her backpack for a while until she found it. She handed it to Chad and watched him fold out the little screen and scan through her footage. "Here!" he gushed. He was so hot when he got all excited about their work like that. "This is what I was looking for! This is from their first session this morning and it's just how I remember it." "Let me see!" Kate cried, waving her hands harder now and making her breasts shake harder. She was too excited to notice. "Come here and I'll show you." Chad uncrossed his legs and spread them wide and patted the space between them with his hand. Kate slid over to him and sat with her back resting against his chest and her bottom against his crotch. He positioned the camera in front of them and played the scene. "See," he asked her? "No. What are you trying to show me?" "Here, I'll play it again. Watch closely or you'll miss it." He played the same clip again. "See Mahalia's face?" "No!" Kate screamed in frustration, grabbing his wrist and pulling the camera closer to her. "What about her face?" "Take it easy or you'll break the camera," Chad warned her, laughing. "Here. I'll try to figure out how to zoom in and slow it down. There!" This time it was unmistakable. It couldn't have lasted more than a second in real time but the signs were unmistakable. Right at the instant that Brad made his final thrust she saw Mahalia's eyes become glassy and her nostrils flair and her mouth open in a wide O! Her chest heaved rapidly, almost like she was hyperventilating, and her arms and shoulders went into spasm. Kate couldn't have been any more certain about it if Mahalia had pulled out a cigarette and lit it. It was an orgasm for sure! "O my god! How could I have missed that? Did she have more than one orgasm today?" "We'd have to study the videos more carefully, but yeah, I think she did," Chad replied, just as thrilled as she was. "I'm pretty sure that she had several orgasms this morning but none in the afternoon. I was watching her closely." "That makes sense!" Kate cried, delighted at the news. "It makes sense that she would have more orgasms in the morning when she's rested and relaxed and fewer in the afternoon when she's tired! O my God! I LOVE you!!" Kate turned around suddenly and practically jumped into his lap, wrapping her legs and arms around him and hugging him tightly while she kissed his cheeks all over. "I love you! I absolutely love you!" She did it all without thinking. It was a few seconds before she realized that she was pressing her naked breasts against his chest and grinding against his crotch. He was looking right at her, wide eyed with surprise, and his cock was stiffening. He brought his hands to her butt and kissed her, full on the lips. "Don't say it if you don't mean it," he told her, looking serious all of the sudden, but a little playful too. "Okay? You've got to take it easy on a guy. I'm having a great time with you, and I want to keep having a great time. But you've got to be careful or I'll fall for you hard. Okay?" "Okay," Kate agreed. She couldn't tell if he was just sweet talking her, but it was good to be reminded anyway. She was having a great time with him too but she didn't want to complicate things by making him fall in love with her for real. "Sorry. I was just so excited I got carried away!" "That's alright," he smiled. "I like it when you get carried away!" He leaned forward and brought his mouth to her neck and kissed her hard. He pulled her closer to him in his lap, caressing her ass through the silky running shorts with his big hands. "I bet you do!" she teased him, running her hands through his hair. She looked down and noticed that the sides of her arms were pressing her breasts together, just slightly, holding them a little higher toward Chad. Her nipples were red and long and plump. She wanted Chad to see them. She felt so desirable and irresistible tonight and she wanted to drive him wild with her body! She brought her hands to his face and forced his head down until he caught sight of what she was trying to show him. He groaned out slow. He leaned forward and took her fat nipples in his warm mouth, one by one. He flicked his tongue across them and sucked and nibbled them while she ground her crotch harder against his, feeling him lengthen and stiffen. He brought his nose to her armpit and took a deep scent of her. There wasn't time to bathe in the stream today and she knew she smelled stronger than usual. She knew it because she could smell herself and she also knew it because Chad didn't have time to bathe in the stream today either and his scent was pouring off him in heavy waves The effect of it was like a drug! The rain was still battering the tarp over the tent and it was hot and close inside and they were both covered with a fine sheen. She brought her hands to his chest and dug her nails in hard until she had his full attention. "Owww" he winced, "what was that for?" "Lean back," she instructed him. "I want to tell you about something." Chad did as he was told. Once she had him on his back Kate kneeled beside him and reached for the waistband of his boxers. Chad raised his ass so she could slide them off. She had to bend forward a little to do it and when his cock and balls sprang free the scent of his crotch was so sharp and raw it made her head swim with lust. Before she knew what she was doing she brought her nose between his legs and took a long breath in, holding and savoring it. She brought her hands to her own waistband and pulled the shorts off and threw them behind her in one motion, nuzzling her nose against his testicles and drinking in his scent. Then she sat up on her knees again and looked down at him in the lamplight. She knew just what she wanted to do. A few deft movements and she was straddling him with her knees. She sat back slowly until she felt her cheeks resting against his upper thighs. She brought her hands to his stomach and pushed down and raised her ass a little so she could position herself just how she wanted, with her wet lips against the base of his hard shaft. She dug her nails into his sides and looked down at him archly, sliding forward and backward a few centimeters each way. Her arms were pushing her tits together again and from the look in his eyes she knew that he was wild with desire. "What's up?" he asked her, playing it cool as always. "I had a dream about you last night," she told him. "Do you want to hear about it?" "Okay. Sure." She was sliding her lips against him and smiling down at him and massaging his sides. "We were back in the hotel in Dar es Salaam, but this time we were in the same room." "Oh yeah," Chad asked. "What we were doing?" "We were having sex, silly! What else would we be doing alone in a hotel room?" "Okay. How was it?" he asked, bringing his hands to her ass and encouraging her to slide a little further along his length. Kate happily obliged. She was so wet for him, and her lips were so plump, and it felt delicious to just wrap herself around him and slither against him like this. "It was incredible," she smiled at him, leaning forward and reaching her hands to his chest. She spread her fingers wide until the tips of her middle fingers were pressed tight against his nipples. "O yeah? How come? What were we doing?" "Hmmmm, let's see if I can remember," Kate teased. She knew she had him eating out of her hand. She could tell by how solid and thick he felt against her wet lips. She pressed her finger tips hard into his nipples and massaged them in slow circles. "O I remember" she smiled down at him, wickedly. "I was on my knees looking out at the ocean and you were fucking me from behind." "Sounds nice!" Chad purred. He looked up at her and watched her while she rode him with her lips. He looked like he was considering his next move. He brought his hands to her breasts, smiling smugly as he bounced them in his hands, just slightly, savoring their firmness and heft. "You look amazing all covered in sweat like that," he told her, pinching her nipples a little when he saw her blush. "Tell me more about this dream." He paused for a second. "Were we using protection?" "No!" Kate smiled down at him, shaking her head from side to side in long slow movements and leaning forward a little further. Her breasts were hanging down and she was so close to him that she felt her nipples against his pecs. She rocked back on her hips a little, closing her eyes and enjoying the feel of her breasts sliding across his hard chest and her crotch sliding against his hard cock, all greasy with her fluids. "We weren't using anything at all and it felt amazing and you know what else?" "No" "When I looked up at the sky there was no moon! Well, there was actually a dark circle where the moon should have been. It was the new moon. And you know what else?" "No" Kate sat up on her knees all of a sudden and crossed her arms over her chest, looking down at him sternly. "Put on a condom and I'll tell you the rest." "Awwww Kate," Chad drawled. "Do we have to? Your pussy feels so amazing and you were just getting to the good part." "Yes, you have to," Kate nodded emphatically. "Do I need to review our whole conversation last night? Be quick about it or I'll lose my train of thought. "Okay okay" Chad agreed, rolling over on his stomach and grabbing a condom and ripping it open with his teeth and rolling to his back again while he slid it on. "Impressive!" Kate teased, looking down at his hard cock in the rubber sheath. "I can see that you came prepared tonight! She sat back down on him and slathered him with her wetness. "Now where were we?" "It was your fertile day and I was fucking you raw from behind." "That's right," she purred to him. "You always pay such close attention! You were fucking me from behind and it was my fertile day and you had your cock all the way up inside me!" She reached down between her legs and grabbed his real cock by the root and angled it. She sat back on it and slid it all the way inside her in one fluid move. "Awww Kate." Chad groaned, grabbing her ass hard in his hands and trying to raise her off of him so he could thrust up from beneath. "Easy, big boy," she gasped. "It's been a couple days since you fucked me, remember. I've got to get used to you again. That's just how it was in the dream. You were stretching me wide open with your big, thick cock and I was cumming all over it!" "Oh yeah?" Chad encouraged her. "Yeah," she cooed for him. "It felt amazing. It felt like my pussy was my mouth or something and I was kissing and sucking and licking you all over. "Awww Kate," he groaned. "You must have looked so hot working your ass like that! "You think so?" she gasped. Without even realizing it she started to bounce up and down on him, just a little first, but picking up pace. She was sitting straight up and he was inside her to the hilt. She was bouncing up and down on him and gasping and her tits were bouncing too. "You think it would look sexy to fuck me from behind?" Chad nodded. "Why don't we try it and find out," she whispered, huskily, still bouncing and gasping. Chad sat bolt upright and took her in his arms, kissing her and holding her and slithering her tongue against his. She was still in his lap facing him and his cock was still inside her and the new angle brought his base against her clitoris and sent hot sparks to her crotch and cortex. She wanted to ride him like that for a while and cum for him but it was the right moment and she'd been waiting for this all day. She pulled herself off him and turned around and positioned herself on her knees in front of him, arching her back and sticking her ass out proudly. She knew it looked beautiful and she wanted to make Chad as hard and long as she possibly could. She wanted to make him wild with lust so he'd take her hard right now and fuck her as hard as possible. Before she knew it she felt his hands on her hips and his fat crown pressing against her wet slit. She imagined what she must look like, all red and glistening and ready for him. A quick thrust of his hips and she was completely and utterly stuffed with cock and loving the feel of it as he pulled all the way out and stuffed her again. And again and again, over and over. "Ohhhh god . . . . Ohhhh Chad" "Awwww Kate" he grunted, "Awww baby. Was it like that in the dream? Were you calling my name out in the dream." "Fuck me harder and find out," she taunted him, leaning forward on her elbows now and sticking her ass up higher. "Awww Kate," he grunted again, leaning forward over her and cupping her breasts as they hung down and swayed for him. He was thrusting into her like a man possessed. "Ohhh god . . . Ohhh Chad." She couldn't believe it but she was pretty sure that Chad was about to set the world speed record for making her cum from penetration. It was just like with Mahalia! It really was possible! Her whole backside was on fire. It was hot and wet and glowing like a hot ember and it felt hotter and wetter every time Chad's groin slapped against her womanly ass. "Ohhh God . . . Ohhh Chad." "You like that darling?" he drawled. "Was it like that in the dream?" "Just like that," she gasped, those white waves beginning to crest and break inside her and those pricks of starlight breaking out like hot hives all over her skin. Her arms and legs and her whole backside were quivering. "Just like that except you weren't wearing a condom," she groaned. "It was my fertile day and you were fucking raw and I was cumming all over you." "Awww Kate," Chad whined. He pushed up all the way inside her and held himself there while he brought his hands to her wrists and pulled her arms out from under her. He pulled her up against him, sharp and rough. They were both sitting up now facing the same direction and he was buried in her to the root from behind. She was bouncing up and down on him with her tits in his hands and his tongue in her mouth. She didn't know how it happened. He was fucking her from behind, but in a new way that she'd never tried before, and she had her neck and her face twisted toward him and she was sucking on his tongue and bouncing on his cock and he was pinching her nipples and she was already cumming. She was already cumming when he reached his hand between her legs and thrust inside her again with his beautiful cock. He pressed his finger against her clitoris and circled it just so. She was already cumming before but now she was cumming much harder. "Oh Chad . . . Oh fuck me." He pushed her shoulders down gently and she collapsed forward again with her ass high in the air and his finger on her clit while he stuffed her with cock. Her ass was jiggling and her tits were rocking and her whole body was quivering. "Oh fuck me . . . Oh fuck me raw and cum inside me . . . Oh fuck me raw and cum inside me and give me a baby . . . Ohhhhh god . . . Ohhhh baby." Chad gave one last thrust, so hard and deep it made her head snap back, and she felt him erupt inside her. "Awww Kate . . . . awww fuck me." He grabbed her by the wrists again and pulled her back toward him until they were both sitting straight up again with his cock buried in her from behind while it pulsed and spurted. He was all tapped out and she could tell the condom wasn't broken. She craned her neck around and kissed him while she felt his heart pounding and his chest heaving and his hands all over her sweaty body. The rain was still pelting the tarp and the air in the tent was hot and close and filled with the smells of sex and pleasure. She wanted to savor the moment. She wanted to feel him all the way inside her like that while her tongue played with his tongue and he caressed her all over. She wasn't done with him by a long shot but she needed to rest and recover. There wasn't any hurry. They had three more condoms if they wanted them, and Chad was a twenty-year-old man. He was so hot for her. She was a woman at her peak. Advanced Primatology Ch. 12 Part 1 Chad held Kate tightly from behind while she rode out the last throes of her orgasm. She was sitting in his lap with his cock inside her. Her whole body was limp in his arms. He had one hand on her belly and the other on her full breasts, still sweaty from their feverish session. She was falling forward and her lungs were heaving as he held her up, caressing her all over. The rain had slowed to a shower by now. He closed his eyes and listened and inhaled deeply through his nose. The air inside the tent was hot and moist and heavy with the scent of saliva and sweat and cum. He loved this part. He tried not to be a jerk about it, because he truly loved and admired the female half of the human species, but he loved this part all the same. He loved how dreamy, and yielding, and open to suggestion a woman became in the moments after he'd satisfied her body. If he played it skillfully, if he kept her cresting from orgasm to orgasm, showing her new positions and new delights and letting her rest just long enough to gather strength for the next round of pleasure, then he could keep them in that state of mind for hours, until the sun came up even, until they'd crossed all their boundaries. He'd seen it happen with dozens of girls. Professor Phare (Kate's soon to be ex-husband) had taught him all about the physical and psychological basis of it in his class last year, explaining the science behind what Chad had always known intuitively about the "chemistry" of sex. Kate was probably thinking and feeling a lot of things right now, but he knew that she was thinking and feeling a few things for certain. He knew that at the peak of her orgasm Kate's brain had released a massive dose of a hormone called oxytocin and that the effects of it were flooding through her. He knew that she was feeling a deep sense of relaxation and security. The little dials in her brain that controlled happiness and physical pleasure had been turned up as high as they could go, and the ones that controlled anxiety and fear had been shut down completely. Her whole body was telling her that she was in the presence of someone she could relax her guard with because he would treat her well, even protect her. He knew that at some level, whether she was aware of it or not, her whole brain and body were producing the kinds of sensations and feelings that can tell her, "This is real love." Professor Phare taught him that a woman always had these kinds of feelings and thoughts, at some level, even if it wasn't conscious, after she'd been satisfied by a male. It was a simple matter of physiology and brain chemistry and it had been proven over and over with dozens of experiments in the lab. They couldn't help feeling that way. At the level of hormones and neurotransmitters it was out of their control! And that didn't mean that women were somehow inferior to men. It was out of his control too. At the peak of his own orgasm he'd been flooded by dopamine—the pleasure hormone—and now he was crashing hard. Research had shown that it was like doing a line of cocaine. The withdrawal made a guy start craving more and more sex, as soon he was ready, usually after a nap. One study that Chad was particularly interested in showed that the "cuddle response" induced by oxytocin was especially high in women when they were ovulating. It was practically off the charts! Professor Phare got really excited talking about it in seminar and the enthusiasm was contagious. He told them about how scientists already know that women have stronger sex drives during the fertile days, and that they signal their availability and willingness to men in a variety of almost imperceptible ways—that women's breasts and buttocks and lips swelled, that they tended to dress in more revealing clothes or brighter colors, that they were more likely to attend social gatherings (clubs, parties, whatever) where there were lots of available males, and that they tended to be especially attracted at those times to males who exhibited aggression and dominance. The tall, broad-shouldered, cocky type was practically irresistible. In fact, one fascinating experiment showed that women in relationships with sensitive provider types (nice guys) were particularly attracted to alpha males (bad boys) on their fertile days, and that they reported feeling far more likely to have sex outside the primary pair bond! Professor Phare got especially excited describing the big contradiction at the center of all this new research. The really mind-blowing part was not only that women were far more likely to hook up with "bad boys" when they had the greatest chance of getting pregnant. It was also that they were wired in such a way that, in the state of post-orgasmic bliss that followed the sexual encounter, their perceptions of the "bad boy" shifted. They started to see him, and treat him, as a "nice guy." The underlying cause was that women were more likely to have stronger orgasms during their fertile days, and from the thrill of transgression. And simple logic dictated that the harder the orgasm, the more careless and risk-taking their behavior would become afterward, because a harder orgasm meant a bigger dose of oxytocin to the brain. So a woman who was ovulating and had just been fucked good and long and hard by a dominant male (Brian didn't put it that way but Chad could read between the lines) would also be feeling incredibly relaxed and connected and trusting. She'd want to have more orgasms with him for sure. She'd want to bond with him. She'd want to meld her body with his in the deepest and most intimate sense possible. Chad knew why it was so exciting to Professor Phare because it was exciting to him for the same reason. When you really thought about it, when you really pushed aside all your preconceived ideas about why people do what they do, it was like nature was specifically designed to provide guys like him with the kind of sex that he had always liked best, for his own fucked up reasons! Hard, impulsive, raw sex with a girl at her most dangerous time, when her rational mind was telling her it was crazy and wrong! That she was crossing a line, no matter how good and right it felt in her body. It was almost like he could see the wheels turning behind their wide eyes as he smiled down at them: that it was crazy to just let go and have hot sex with this guy who she barely knew and who was a little bit teasing and mean to her, and who talked like a hick. Even if it was kind of a turn on how confident and brazen he was to flirt with her openly at the party. She had a boyfriend and she was surrounded by her sorority sisters for christ's sake! She wasn't going to just drop her panties for him and spread her legs! Even if it did drive her wild the way he came onto her so hard and pushed her buttons like that. He was kind of sweet at the same time, wasn't he? He listened to her stories, didn't he? He had a sweet face to go along with that hard, lean body with the slim waist and the broad shoulders and the tight butt. Before long they'd be shaking and moaning and gasping and doing whatever he asked them. Chad loved women. He truly did! And he didn't mean any disrespect for thinking about them this way. He even felt a little guilty about it! But in the end it was just a fact. Women were designed by nature—when you really thought about it from the right perspective—to desire reckless sex with guys like him the most when they were at greatest risk of conceiving. It didn't matter if they were richer than him or smarter than him or in a monogamous relationship or his professor or anything! And if he played it right, and treated them right, they were designed to have the most trust for him at precisely those times, the deepest need to connect with him fully. Kate was way more beautiful and intelligent than any of the dozens of coeds he'd slept with since he got to UNC (he had a decent chance of breaking the century mark with his senior year still ahead of him). And she was a real woman, no doubt about it. He could see it and feel it and taste it. He looked down and saw that his cock was still buried inside her shapely rear. He eased himself out, careful not to let the condom slip off, and laid her down gently on her side on the sleeping bag facing away from him. He spooned up behind her and reached his arms around so he could hold her belly and breasts again. She scooted closer and wiggled her ass against him. Kate was a beautiful woman, for sure, and a good friend too, though it still felt weird to think of her that way. His head was still swimming from the fact that he would be living in her guesthouse for the rest of the summer, and they'd be lab partners during the days (with benefits during the nights!). He couldn't believe his luck! Even for a young guy of his unusual good fortune this was beyond expectations! Not only was it a really interesting job to help her analyze the samples from the trip, and not only was it super cool of her to help him figure out a way to live independently of his deadbeat mom over vacation, but beyond that she was an absolute wildcat in the sack! There were so many ways he wanted to penetrate and lick and finger her and they were going to have time to try all of them! He cupped her breasts in his hands and noted again that they felt bouncier and riper than the night before. She was a real woman, not one of those dime a dozen co-eds that were always spreading their legs for him and letting him fuck them silly. But she was a female all the same. She had the same biochemistry and the same brain structure and everything. She was feeling and thinking all the same kinds of things that girls usually felt and thought when he slipped his cock inside them and fucked them long and hard and well. She was feeling like pretty soon, after a short rest, she wanted to fuck him again, maybe harder this time, and again after that, until there were no more barriers between them. He felt his cock stiffen as he remembered how sweet and luscious her ass looked when she got on her knees in front of him and held her tail up high, and how he thrust into her like a madman while she called out all kinds of crazy things! It blew his mind every time how completely and passionately she threw herself into her deepest fantasy: of fucking him raw . . . and letting him cum inside her . . . on her fertile day . . . making her belly full. It was obvious that it was something that part of her actually wanted to happen, and it made him dizzy with lust and confusion the way she let herself act out that desire in vivid detail. In one sense it scared the crap out of him! There was no way he wanted to be a dad before his twenty-first birthday! No way! But at the same time, in another sense, he wanted it too. He wanted it badly. That's why it made him feel so frustrated and edgy when Kate made sure to take careful precautions with birth control and "rules" and such before she let herself go and acted out those little impregnation scenes with him. My god they were hot! But he wanted it to be more than a fantasy. He wanted her to want it for real. He wanted her to ask him for it. He wanted to push her and push her until she crossed the last boundary a woman could have with a guy, until she asked for his baby. It was the right moment and he was determined to see how far she'd take it. Kate was a complete puzzle. She gave him a weird ache in his balls, and a queasy feeling in his stomach, and he wasn't sure he liked either of them. He had no idea where any of this was headed with Professor Morgan. He scooted away from her and rolled her over on her back so he could lie on his side and survey the full length of her, naked and spent and sweaty. With a little coaxing she'd be ready to fuck again in no time. He brought his hand to her crotch and spread her legs apart, just a few centimeters, and cupped her wetness with his hand. He couldn't help himself either. He was still a player, after all, and Kate was a very, very attractive female. She was more than that. She was a beautiful woman, and she was playing his favorite game. Part 2 How could I have forgotten about this place, Brian wondered, as he watched Elise, Ellen, and Alex chatting in the small circle of steaming, bubbling water. They were in the wood-fired hot tub that was attached to the main lodge where Alex and her husband Roger lived in the caretaker's quarters, near the luxury suites where the ultra wealthy guests stayed when they flew in by helicopter from Europe or wherever. It was normally off limits to scientific researchers (university budgets couldn't afford the very best rooms and amenities at the lodge) but he and Roger had ended up back here once, a few years ago maybe, after a hard night of drinking. The design of the place was ingenious. Roger had built high stone walls all around the tub for privacy and left the roof open to the stars. There was a mosquito net over the top to keep out the nocturnal insects. Brian was lying in a hammock just to the side of the tub watching the three women relaxing, still in their bikinis from a long afternoon of snorkeling and sunbathing. He'd already made up his mind that nothing would happen with Alex. Brian was too good of a friend, and he was pretty sure that Alex would refuse him anyhow, despite the vibes he'd been feeling. More importantly, he wasn't going to do anything stupid (like fucking the caretaker's wife) to jeopardize his access to the lodge and the chimp preserve. They were too important to his career. But Alex was a fine looking woman all the same, and he was having too good a time to part with her company entirely. He wanted to observe her. Twenty minutes ago, thereabouts, he'd yawned theatrically and winked at Elise while he told the other ladies that he was wasted from all the sun and weed and booze and he was going back to the cottage to sleep. "But I don't want to walk back to the cottage all alone!" Elise protested, snuggling up a little closer to him. They'd been all over each other all day and it must have been obvious to Alex that they were sleeping together, if it hadn't been already. He could see the disapproval and moral judgment written all over her face. She knew that his marriage with Kate was over, except for the technicalities, but he could tell that she didn't think highly of him for seducing a student. For seducing several of them! Still, she hadn't said no when Elise invited her to go snorkeling with them for the day, even though her husband was away on an errand. She might disapprove but she was definitely curious about something. "It's scary out there in the dark with the snakes and everything," Elise whined. "Why don't you just 'sleep' in the hammock," she suggested, winking at him slyly with her back to the other girls, "and I'll wake you up when I'm ready to go back to the bedroom?" "Okay," Brian agreed, making a show of yawning again and standing up in his slim fitting swim trunks to make his way to the hammock. He pulled a towel over himself as a blanket and arranged himself so he could see all three of the women. He was in shadow and they were in starlight and he had his fisherman hat pulled down over his eyes. They couldn't tell he was looking, everyone except Elise. She knew the game he wanted to play for sure. She was a real partner in crime, that girl. He was definitely attracted to Alex and there was definitely a little chemistry between them, not that either of them were going to act on it. But he wanted to see what would happen if he left her alone in the tub with Elise and Ellen. He wanted to see if she would cut loose a little in the company of these younger girls, so much wilder than she was, and unattached. He wanted to hear what they might talk about. He smiled to himself thinking that Elise would know exactly the kinds of things he'd want to hear, the kinds of things that would turn him on. Alex was about Kate's age, he reflected, maybe a few years younger. He'd finally gotten a good look at her body in the conservative plaid bikini she wore to the beach that afternoon (far less conservative, he noticed, than the one-piece she wore when her husband was with her the day before). Her torso and arms were surprisingly petite and toned. So while her breasts weren't especially large, objectively speaking, they looked positively buxom on her small frame. But her best quality by far was the contrast between her tiny torso and waist and the womanly curves below it. She was delicate up top but she was generously proportioned down below, all through her thighs and hips and ass. He smiled to himself again remembering watching her snorkeling beneath him earlier in the day, kicking her feet and wiggling her bottom in the clear blue depths. He felt his cock stir in his trunks and he reached a hand inside. He wasn't going to jerk off or anything while he spied on his friend's wife. That would cross a line. But he wanted to feel himself stiffen. Brian was a connoisseur of female bodies and he specialized in discovering diamonds in the rough like Alex, in detecting the hidden signs of voluptuousness and beauty in women who weren't conventional knockouts by any means, and who were too prim and self-doubting to flaunt their assets anyway. It was a skill that came in handy working in the sciences and traveling to all those boring conferences and such where the most attractive women weren't built like models or anything. You had to look a little deeper to see through the pantsuits and severe glasses and find the really exceptional bodies on women who were sometimes right on the borderline of plainness. The benefit was that women like that were often inexperienced sexually, and secretly dying to experiment. They were unaccustomed to the chase as well. So they were vulnerable to a decisive move by a seasoned player like Brian. It was easy to catch them off guard with that first salacious comment, or kiss, or grope, and once you had them in bed it was easy to take them to new heights. That's why he decided that he couldn't stay in the hot tub with the ladies. The longer he stayed in there, and flirted with Elise, and watched Alex get all bothered and flustered by the fact that he was fucking a twenty year old girl, and felt the tension between them mount, the greater the chance that he was going to make a move on her before the night was through. She'd reject him, probably, in the end. But he couldn't take the risk. When a player like Brian made a play for a wallflower like Alex all bets were off. There was no telling what might happen. She might let his hand stay on her thigh just a little too long (they were just playing after all!) or she might let him kiss her (just playfully!) the way he'd been kissing Elise, the way he'd be kissing Ellen too in all likelihood. It was something about the way she responded when Brian suggested that the four of them adjourn to the hot tub later that evening on the boat ride back from the reef. Alex was wearing a sheer white cover up and he could make out her curves in the bikini. She didn't say anything at first. Brian felt oddly excited trying to make out her expression through the over-sized round sunglasses she was wearing. She thought about it for a couple of beats and then she bit her lip and wrinkled her nose. "Okay," she agreed. "But you can't tell Roger. He'd murder me if he found out I was partying out there with you guys. That hot tub is his pride and joy. It would be a royal bother for him to fix it if anything got broken." It was all perfectly innocent. But something about the way she said it was so suggestive all the same. She was a married woman and she was breaking her husband's rules. She was just a little too excited by it. She was enjoying herself just a little too much doing something she wasn't supposed to, let alone with a man who was known practically across the globe as an accomplished seducer. Advanced Primatology Ch. 12 The sound of Elise's voice brought him back to the present. "I love hot tubs," she purred, stretching her arms over her head. "They always make me so horny. I don't know why. Maybe it's because they always remind me of my favorite porn movie." Brian laughed inwardly and settled into the hammock more deeply. He could see where Elise was going and he was prepared to enjoy himself thoroughly. "What was it," asked Ellen. She sounded a little drowsy and out of it. "Oh it was a real classic," Elise replied enthusiastically. "It was one of those 'Taboo' movies. I think the second one. The one where the brother and his girlfriend and the sister are in the hot tub . . ." "Yeah?" said Ellen, perking up a little. "What happens next?" "You haven't seen it? You should! It's hot! What about you Alex? Have you seen it?" "Maybe I've seen it once," she replied, her cheeks flushing pink. "Maybe Roger showed it to me one time." "It wouldn't surprise me," replied Elise, cheerfully, careful not to make Alex feel more embarrassed than she already was. "It's one of the classics! Everyone's watched that one!" "Not me," said Ellen. "So what happens?" "I can't remember all the details," said Elise, making big eyes at the other two women. "But I think that the brother slips out of the tub for a while and the girlfriend starts telling the sister about how good he is in bed, and how big his cock is. Then they decide to take off their bikini tops and work on their tan lines." "Sounds good," said Ellen, perking up a bit more. "Then what?" "I knew you'd like it!" Elise laughed, arching her eyebrows and splashing some water toward Ellen. "You love all that 'whoops I'm a lesbian' kind of stuff." "Elise, stop it!" squealed Ellen, splashing her in return. "Tell us the story!" "Well, long story short," continued Elise, cutting straight to the good part, "They both get horny and the sister ends up on her back on the couch in the living room with the girlfriend going down on her." "Nice!" purred Ellen. Alex wrinkled her nose so hard it looked like she might hurt herself. But Brian noticed that she was paying close attention. She'd had a few drinks over the course of the afternoon, and she even smoked a little of the joint Brian passed around when they first got into the hot tub, so her inhibitions were definitely lower than normal. "I know!" exclaimed Elise, signaling to Ellen that she found the lesbian bit kind of a turn on too. "But that's not the best part." "Yeah? What's the best part?" asked Ellen, leaning forward a little, clearly excited. "The best part is that it was all just a set up. The brother has been dying to have sex with his sister for years, and the girlfriend has agreed to seduce her for him. So when she looks down after a few minutes of closing her eyes and enjoying herself she realizes that it's not the girlfriend going down on her. It's her very own brother! And he's doing a very good job!" "Yeah? Don't leave me hanging!" "Well, she tries to resist at first. But it feels so good, and her brother looks so good. And then he just smiles at her, all cocky and smug, and climbs on top of her and fucks her—hard!—while the girlfriend plays with her tits and watches." "O my god," gasped Ellen. "I know!" Elise laughed. "It's my favorite. I found the DVD in my dad's bureau when I was home from college for the summer and my parents were both out. I popped it right into the television at the foot of the bed and before I knew it my panties were around my ankle and I was fingering myself silly!" "On your parents bed?" Ellen gasped again. "That is so wrong!" "I know," Elise laughed. She turned to face Alex. "Did you like that scene, when Roger played it for you, I mean?" "Not really," Alex answered, wrinkling her nose again. "I'm not into the whole incest thing, I guess. Or the non-consensual stuff." "Of course not!" Elise replied in a gently mocking voice. "It's positively indecent! But I bet Roger liked it, didn't he?" "Maybe a little," Alex admitted, laughing despite herself. Elise was a real master at getting people to let their guard down and admit things to her. She was studying to be a psychologist and she had the potential to be a very good one some day, Brian reflected, if only she had an ethical bone in her body. God help her patients if she got it into her head to play with their minds like she was playing with Alex right now. "Do you like other kinds of porn though?" Elise asked. "Not really," said Alex. "We don't have internet out here, remember?" Elise raised her eyebrows like she didn't quite believe her, but she let it drop. "What about you?" she asked Ellen. "Yeah, sure. I like porn. I guess." "Oh yeah? What kind?" "Well," Ellen hesitated, feeling self-conscious suddenly. Her elbows were resting on the side of the tub and her breasts were just above the water line. Brian could see her nipples poking straight out through her bikini top. "Are you sure Brian's still asleep?" she asked, squinting into the shadows. "I'll go check," said Elise. Elise climbed out of the pool and scampered over to him, lifting the hat off his head just slightly. Brian winked at her and she winked back. "Out like a light!" Elise reported, scampering back into the water. "Now where were we?" "Well, if you must know," Ellen continued, blushing fiercely. "I like anything with a very big cock! It doesn't have to be a real cock, actually. It can be a very big dildo or strap on or whatever. Basically, I like anything where a 'naïve' type gets fucked very hard by a very big cock!" Elise burst out laughing. "Then you must love just about every porn video ever made!" Alex was laughing too. Brian could tell she was really enjoying herself. She probably didn't have many opportunities for female bonding and companionship like this, out here in the wild alone with her husband and a steady parade of mostly rich, middle-aged guests. Elise eyed Ellen curiously, trying to judge how far she could push her. "I thought you might have a little size queen in you somewhere," she teased, reaching out and poking Ellen in the ribs. "Is that why you fucked Chad? Because you were curious about big cocks?" "Elise!" Ellen gasped. "Who's Chad?" Alex piped up, still wrinkling her nose but laughing a little and enjoying the girlish fun. "Who's Chad?" Elise mimicked her, rolling her eyes. "You know, the tall ripped soccer player with the long black bangs and the piercing blue eyes. Don't even pretend you haven't noticed him." "Maybe I noticed him a little," Alex grinned. "O my god! You slut!" Elise teased. She and Ellen were both in hysterics. "So anyway," Elise proceeded, once they'd all recovered, "is that why you had sex with Chad? Did you want to see what it felt like to have one of those big porn star cocks inside you?" "Maybe," Ellen replied, her cheeks reddening, and a look of slight resentment passing like a shadow across her face. Brian could see Alex flushing bright red too. Damn she looked sexy. He was rock hard under the towel and gripping himself tightly. "And was it everything you hoped for?" Elise asked. "I think you know," said Ellen. Both girls doubled over laughing again. "Where's Chad now?" asked Alex, blushing a deeper shade of red when the realization dawned on her. "O my god! Is he the guy who's alone in the mountains with Kate, with Professor Morgan I mean?" Elise and Ellen both nodded at her, eyeing each other meaningfully. "What?" Alex asked. "You're not suggesting that she's having sex with him are you? With a college guy?" "Oh no, of course not," Elise replied, the sarcasm dripping. "I hope so for her sake!" Ellen cut in, "She's been eye fucking him ever since she saw him in the airport back in Raleigh! Poor lady. I thought she'd die from sexual frustration." Brian felt like he'd been kicked in the stomach. He felt a flash of anger toward Elise for letting the conversation stray into such complicated waters. He was praying that she'd steer things back in a lighter direction before long. "You girls are awful!" Alex chided them, rolling her eyes and laughing. "Not that I can blame her," Ellen picked up the thread, sighing. "He is very pretty to look at." "You know what he told me the other day?" Elise jumped in. She arched her eyebrows at Alex and splashed some water toward her. "He told me that he thinks that Mrs. Roger Briggs over here has a terrific little body! He told me that he thought she was really cute, and that the South African accent drove him wild!" "He didn't!" Alex cried. Brian gripped himself again, enjoying the new direction. "He did!" Elise countered. "That cheeky little bastard!" she cried. "I must be fifteen years older than him!" "So is Professor Morgan," Ellen teased. "I think that's part of the appeal!" "O come on," Elise pressed her. "Don't act so surprised that a hot young guy like Chad is attracted to you. You must get hit on all the time out here. By the guests and everything. I mean, you're a gorgeous woman with a hot little body in the middle of nowhere. Men must be jerking off to you furiously every night, all over the lodge!" "Stop it!" Alex protested, still laughing. "That's a revolting idea!" "You don't seem revolted," Elise taunted, sticking out her chest and tweaking her nipples a little. "You are both horrible young women!" Alex shouted, in mock horror, splashing some water at Elise and Ellen and then covering her breasts with her hands. Brian had noticed the same thing. Alex didn't seem revolted at all. Even through the thick fabric of the plaid bikini he could see her nipples clearly. She bit her lip and rolled her eyes and Brian groaned inwardly as he felt himself under the towel. "I KNOW you've been hit on by lots of guests," Elise carried on, "and I KNOW you've never strayed. It's obvious just looking at you that you're the faithful type. And your husband is such a catch! He's in great shape, for a guy his age, and he's adorable too! Don't you think so, Ellen?" "He's really cute," Ellen agreed. "But what I really want to know," Elise continued in her best grown-up, sultry voice, sliding over a little closer to Ellen and draping her arm around her shoulder casually. "What both of us REALLY want to know is . . . . well . . . have you ever been tempted? Right Elise? Aren't we curious about that?" She leaned in close to Elise and placed her finger on the tip of her nose, flirtatiously. "What do you mean?" asked Alex, pretending not to understand. It was obvious that she was flustered, not only by the question but also by the sudden sexual tension between the girls. She wasn't expecting that. Brian could see the wheels turning behind her eyes. She was wondering if Elise and Ellen might start fooling around in front of her, while they were talking about all these illicit topics. And she was wondering if that was harmless fun, or if it would break some more of her husband's rules. "She means," Ellen clarified, recovering her composure after the initial surprise of Elise's sudden advances, "has there ever been a guest who made a move on you and you didn't find it revolting. Even though you turned him down. She means has there ever been a guest who you fantasized about." Elise nodded. "Yeah, that's what I meant." "Of course not" Alex snapped, but she was still smiling a little. "And anyway, I wouldn't tell you about it if I had." "So you have had fantasies!" Elise snorted, poking Ellen in the ribs until she laughed too. "Mrs Roger Briggs I am shocked! Shocked I tell you!" "Come on, tell us about it!" Ellen pleaded sweetly. "It's just us girls. It's just a little harmless chit chat." Brian watched Alex carefully as she eyed the other girls uncertainly. Her elbows were on the edge of the tub and her back was arched away from them in a way that made her chest stick out prominently. He loved that adorable way she had of biting her lip and wrinkling her nose. He could tell that Alex wasn't quite sure what she'd gotten herself involved with and that she was still trying to figure out if it actually was harmless. Were Ellen and Elise trying to seduce her or something? Did she find it exciting? It was a crazy idea! It was just like Ellen said. It was just a little innocent chat. "Maybe I will," teased Alex. "But you have to tell me something first." "Tell you something!" Elise protested. "I just told you that I fingered myself to orgasm to an incest video on my daddy's bed!" "Yeah," chimed in Ellen, "and I just told you that I have a fetish for monster cocks!" "I know, I know," Alex laughed, "But you have to tell me something else. Come on. It will make me feel better. I'm a married woman. It means something if I admit that I've been tempted by another man. That I've fantasized." "Okay," Elise agreed, pleased by the sudden progress, but trying to keep cool. "What do you want us to tell you?" Alex turned to Ellen. "Tell me about your first time with Chad." "Oh you're curious about that, are you?" teased Elise. "Perhaps just a little," Alex whispered. "Well. Get on with it!" "It's not much of a story, really," Ellen began, shrugging her shoulders indifferently. "I was dancing with my girlfriend Courtney back at the hotel in Dar es Salaam. We were both pretty buzzed and Courtney was making some serious moves on me and I was seriously attracted to her! But I still couldn't believe it was happening. I'd never been with a girl before. I'd never even thought about it. Not seriously, anyway. I wanted to be with her but I didn't think I could go through with it. Then all of the sudden Chad was standing there next to us shaking his hips and smiling and giving me those sweet blue eyes." "And?" asked Alex. She was trying to keep her composure but Brian could sense her excitement. "And . . . the next thing I knew all three of us were naked on the bed in Chad's hotel room. I was on top of him riding him and Courtney was sitting on his face. We were making out and she was feeling my tits and Chad's cock felt like it would split me wide open. I was making so much noise! I came so many times I lost count!" "No, not much of a story!" Ellen commented drily, fanning her face with her hands. "Right, Alex?" Alex laughed, exhaling audibly, and fanning her face too. "No. Nothing out of the ordinary." "O come on!" Ellen pleaded. "I'm not that much of a slut, am I? You must have done some crazy stuff back in the day, huh Alex, before you met Roger?" "Nothing like that, my dear," Alex answered, still laughing. "I'm sorry. I mean, I wasn't a virgin or anything when I met my husband. But I never did anything that wild!" "It's a hot story!" Elise jumped in. "Chad is very seductive. He's sweet and fun like that. But do you know what I like better?" "What?" Elise asked, relieved to change the subject. "I like it when a guy just takes you," said Elise, making dreamy eyes. "When a man just takes you, that is." "Is that what it was like with Brian the first time?" asked Alex. "Oh you're curious about him too, huh?" Elise gibed. "Perhaps just a little," admitted Alex. "He and my husband have been friends for a long time and I've always been a little curious about him." Brian had a raging hard on. Alex's whole face and shoulders and chest were flushed bright red and it was everything he could to not to slip out of the hammock quietly and slide into the hot tub next to her. "He is a very attractive man!" Elise sang. "He has attractive qualities, yes," replied Alex, rolling her eyes. "Just tell us the story." "It was the end of the year barbecue for the anthropology department and Brian was there, manning the grill as usual. I'd been crushing on him all semester, like most of the girls in the class." "Not me," Ellen protested, wrinkling her brow in displeasure. "He's old and he's got a little gut and everything!" "O don't even pretend," Elise shot back fiercely. "You'd fuck him for sure if he made a pass at you." Ellen didn't say anything. "Well, as I was saying, I'd been crushing on him all semester so I dressed up for the party. A cute little sundress to make me look like a grown-up. Eye shadow and lipstick. The whole works. We chatted and flirted at the grill. We played a little frisbee. He was devouring me with his eyes. At the end of the party he offered me a ride back to the sorority house in his Bronco. He talked to me the whole time about how smart I was and how impressed he'd been by my work all semester and the whole time he was looking me up and down from head to toe. I was afraid he would drive off the road or something. But my whole body was tingling. I was wet just from him looking at me! Then he asked if I wanted to see something amazing. I sure did! He drove us out to a point over a lake where we had a nice view of the sunset. He shut off the car and turned and looked at me. Then he reached over and grabbed me by the back of the head and kissed me hard. He didn't ask me or anything. One minute he was driving and the next thing I knew his tongue was in my mouth and his hands were on my tits. Another minute and we were in the back of the Bronco and my panties were off and my dress was around my waist and he was fucking me hard! It was the hottest sex ever! I loved the way he just took me like that! I wanted it and all. It wasn't rape or anything. But he took me all the same. It was just so primal!" "Okay, that's kind of hot," Ellen admitted. "But I still wouldn't fuck him!" "Yeah sure" teased Elise. "You want to put money on that?" Ellen didn't answer. "Okay," Alex whispered. Her voice was barely audible over the sound of the bubbling water, and the chanting insects, and the crackle of the flames beneath the tub. Brian could tell that she was really turned on. "I'm ready to tell you my story now," Alex continued, her voice sounding strangely distant. "His name was Sergei . . . " "Go on," said Elise, trailing her fingers along Ellen's shoulder. She was trying to keep things quiet and calm. She didn't want to break the flow. "Tell us about Sergei." "What do you want to know?" asked Alex. It was hard to read her expression. She looked excited, yes, but distressed and pained at the same time. She looked like she was about to tell them about something that she'd never told anyone, something that made her feel hot and ashamed all at once. "How would you describe him?" Ellen asked, encouragingly. "How would you describe him in four words?" Alex blushed fiery red, but she answered right away: "Hot. Russian. Helicopter. Pilot." "Oh this is going to be good," Elise cried gleefully, arching her eyebrows at Ellen, and sliding closer to her. "Well, tell us the story!" "He was the helicopter pilot for a wealthy Russian oil executive," Alex began, in a dreamlike voice, like she was in a trance or something. It sounded as if she'd been waiting to tell someone the story for years. Like she'd practiced it. "There was this weird chemistry between us from the minute he landed. It's true that lots of guests have stared at me, and flirted with me, and even hit on me before. But this was different. Every time I came into the room he would stop and turn and look me up and down, very slowly, and smile knowingly. It was so obvious! It didn't matter if his boss was around, or if my husband was around or anything. He looked at me like I was a piece of meat and he was trying to decide how to cook me for dinner!" "How'd that make you feel," Elise asked in a whisper. Brian was listening with baited breath, hard as steel, and holding himself by the root. He stroked himself a couple of times before he realized what he was doing. He watched Elise grab Ellen's hand under the water. "It pissed me off royally!" Alex spat. "I was pissed at Sergei and I was pissed at my husband too. I complained to him about it lots of times but he pretended not to notice. Not that he could have done anything about it. He couldn't make trouble for a wealthy guest like that. Besides, I think the oil executive enjoyed it. I think it was a game the two of them liked to play. A routine they'd developed during their travels together. It wouldn't have mattered if Roger complained. But it was unbearable for me! I tried to dress as conservatively as possible and to avoid his company, but it was the hot season and I couldn't help showing a little flesh now and then. And Sergie was always around to see, and to be seen. My god! I don't think that man wore a shirt the entire two weeks he was here!" Advanced Primatology Ch. 12 "Did he have a nice body," Elise asked, her voice catching a little. She and Ellen were both completely enthralled, staring at her with rapt fascination. It was like watching the person they knew disappear all of the sudden and another personality take over completely. "Yeah, he did," Alex nodded, her eyes focusing again as she remembered where she was. "He was rippled with muscle from head to toe, and he had . . . he had lots of tattoos." "Nice," Ellen purred. "Tell us about them." "I don't know," Alex blushed. "They were just designs really, but they were very well done. There were flowers and long pointy leaf shapes all over his shoulders and chest and sides and they looked very nice on him. I don't usually like tattoos, but I liked his. I remember one particular day, after he and the executive had been here for about a week and we were all feeling more comfortable with each other. That happens sometimes when guests stay for an extended period during a slow time, when there's nobody else at the lodge, especially if the guests are friendly and outgoing like they were. They become like part of the family, almost. Like friends. Sergei came into the kitchen when Roger and I were cooking dinner for him and his boss. The kitchen is normally off limits to guests, but he'd been pushing all kinds of boundaries for days, subtly, shifting them further and further. Roger didn't protest and neither did I. Sergei was wearing nothing but his swimsuit. It was short and tight. He was still wet from his swim. It was hot in the kitchen, and I wasn't expecting him to come in, so I was dressed less conservatively than normal, to say the least. I was wearing a wife-beater with no bra underneath and a tiny pair of spandex shorts. I'd practically sweated through the shirt and it was clinging to me all over. Sergei took one look at me and his eyes went wide. He walked right around the counter until he was standing next to me at the stove, practically on top of me, and do you know what he did then?" "No," Ellen whispered, her voice strangely raspy. Brian was starting to wonder what the girls were doing with their hands under all that bubbling water. "He looked right at me," Alex continued, her voice sounding distant again. "He looked right at me with a look more full of desire and arrogance and filthy thoughts than any look that any man had ever given me. He looked right in my eyes, standing maybe six inches away from me, and then he let his eyes travel slowly down my whole front—down my neck and shoulders and breasts and stomach and crotch and everything, right down to my toes. Then he raised his eyes and let them travel up my body, still slowly as he liked, almost daring me to say something. Daring my husband to say something! By the time he got to my breasts again my nipples were hard. I didn't know why. Thank god my husband was standing behind me so he couldn't see. Sergei looked in my eyes again and smiled, so arrogant! He looked at me like that, with my husband standing right on the other side of the counter, and then he . . . he reached out his finger toward me, slowly, and he . . . he stuck it in the sauce. He stuck his finger in the sauce I was stirring and then he pulled it out slowly and looked at it all around, just dripping off his finger. He held it to his nose and smelled it. Then he put it in his mouth and sucked the sauce right off it, loud and rude. Then he stepped back and looked me up and down again, real slow. He looked at Roger and smirked. 'Needs more stirring,' he said, smiling his cocky smile." He kept right on standing there. "What did you do?" Elise asked quietly. "I was furious!" Alex hissed. It was like she was reliving the memory all over again and all the intense, unresolved emotions were flooding back to her. "I couldn't believe that Roger would stand for that. That he wouldn't defend my honor or something! That he wouldn't even acknowledge what had happened! I felt like I'd just been violated! I threw down the spoon and stormed out of the kitchen. Next thing I knew I was in the bathroom shaking. I was full of rage. But that wasn't the only thing I was feeling. I couldn't believe what was happening in the pit of my stomach, and what was happening between my legs. It made me feel nauseous but I couldn't deny it. It was too strong. Before I knew what I was doing I stuck my hand in my shorts." "Were you wet?" Elise whispered. "Yeah," Alex nodded, her eyes looking far into the distance. "I was soaking wet. And do you know what I did?" "What?" Ellen asked, her voice hushed. "I can't believe I'm about to tell you this," Alex said, exhaling loudly, and leaning her head back to look up at the stars through the mosquito net above them. "I stood there at the sink and looked at myself in the mirror for a long time. I guess I wanted to see what Sergei had seen. What he desired so much. I've always known that I have an appealing figure, in my own way, but somehow I never realized until that moment how lewdly sexual my whole body was, how it was curved and swollen in all the right places that a man like Sergei would appreciate, That would attract his attention. It was like I was seeing myself through his eyes. I was still flushed with anger and excitement and the contrast between my pink skin and the white top was fascinating to me. The wife-beater and shorts left almost nothing to the imagination. I couldn't believe he'd seen me like that! I couldn't believe that it excited me! I pulled down my shorts and spread my lips apart with my finger and looked at myself in the mirror again. For some reason I wanted to see it. I wanted to see how red and swollen and wet he'd made me. Like a pot of sauce. I stood there inspecting myself in the mirror, and stirring myself, amazed by what he'd done to me. Then I fingered myself until I came." "Hot!" Elise mouthed to Ellen silently, her eyes wide with surprise. They were practically in each other's laps. "What were you thinking about?" she asked Alex. "When you fingered yourself." "I was thinking about Sergei, of course," Alex answered, as if she was puzzled by the question, almost irritated. "I was thinking about what might have happened if everything had occurred exactly the same way except for one thing . . ." "What's that?" asked Ellen. "I was thinking what might have happened if Roger hadn't been there. If he'd been off in the boat with the executive or something." "Did you wish he had been?" Alex nodded. "Part of me did, yeah. I was standing in the bathroom watching myself in the mirror, cumming hard, in big waves, one after another. I'd peeled off the wife-beater at some point. I don't know when. Part of me was wishing that Sergei could see me cum like that. Could see me naked like that. Part of me was wishing that he'd walked into the kitchen and stuck his finger in my sauce and sucked it off just like he did. But I wanted him to keep going this time. I wanted him to just pick me up and take me. I wanted him to just pick me up and spread me on the counter like a piece of meat and take me!" Elise and Ellen were completely silent, awestruck by how much raw desire this seemingly prim married woman had just confessed to them in her posh accent. They were struck dumb by the sheer intensity of it. "What happened next?" Ellen asked, finally, when the silence and the tension grew awkward. "Did anything ever happen between you and Sergei?" "No," Alex replied, shaking her head vehemently. "But things definitely changed for the second week of his visit. I stopped dressing conservatively, for one thing. I dressed the way I do when the lodge is empty, when it's just my husband and I. If Roger didn't give a fuck then I sure didn't! I wore bikini tops and short shorts and whatever the bloody hell I wanted. And Sergei was around me like a fly on shit let me tell you! He was absolutely delighted by the change. My husband played dumb (maybe he was dumb!) but I guess Sergei and I both knew that I was dressing for him, at some level, that when I picked out my outfits every morning, or decided to change into something different to do the dishes at night, I knew he'd be looking at me in whatever I put on. It was almost comical how pleased he was, how eager. He was in the kitchen 'helping' me cook three times a day. Breakfast, lunch, and dinner. He was there in the morning when I came out of my bedroom in my tight tank top and short running shorts with nothing under either of them. He stood there the whole time while I cooked eggs and bacon for him and the other men. He told me amusing stories about the army and about some of the eccentric rich men he'd piloted for. He was funny and charming when he wanted to be. And he was there in the evening while I washed up after dinner wearing my bikini top because we were in the middle of a heat wave and it was sweaty work and that's what I normally wore to do it. If Roger didn't want him in the kitchen then he could have told him to leave! Sergei would stand across the counter from me and take the dishes from me, one by one, and dry them with a towel and stack them, his eyes never leaving me. I knew why he was standing there. I knew he liked to watch me when I did the heavy pots and pans, leaning toward him a little and scouring them, hard. I wore conservative tops at first, but, like I said, it was a very big heat wave, and as the days went by the tops got more and more revealing. And as my resentment at my husband built, and the sexual tension with Sergei grew, I guess I scoured a little harder. I guess I gave him a little show." Alex stopped and looked at the other girls, almost daring them to criticize her. She seemed edgy. "Roger was there with us most of the time, at first. But then he started being out on errands more often. The oil executive was always asking him to do some special favor for him, and as soon as Roger was out the door Sergei would walk in, smiling and telling jokes in that thick accent, shirtless as always. It was starting to grow on me. I liked the attention. I looked forward to it. I liked his body and his tattoos and his shaved head. I liked how close he stood to me. I liked it—I don't know why but I did!—I liked it that he looked at me the same way—with just as much desire—whether my husband was there or not. He was always very careful, in his own way. He never touched me. He never gave Roger anything obvious to object to. Or me. My sense was that he'd played this game with lots of men's wives, lots of men who were paid by the executive. But the more I got used to the idea the less it bothered me. It was something about the fact that Sergei desired me enough to be willing to exploit me, in a sense. I didn't work for him, or for the oil executive, technically, but they were both my customers all the same. He knew that it was part of my job to be friendly and accommodating to him—I work in the hospitality business after all—and he was very clever about the way he used that to his advantage, without pressing it too far." "Did you keep fantasizing about him?" asked Elise. "No!" Alex shook her head hard. "I mean, a lady can't help her daydreams, but I never masturbated to him again. I felt awful after that first time. It felt like cheating! I was too scared of what might happen if I got used to the idea of actually being with Sergei. I was too afraid I might cross the line. There were so many opportunities!" "Tell us about one," said Ellen. "Well," Alex began, brushing the hair out of her eyes. "One night I couldn't sleep and I felt thirsty so I came out to the kitchen for a glass of cold water. It was maybe 2am. I must have been half asleep still because I didn't give a single thought to what I was wearing. I was standing at the refrigerator filling a glass of cold water from the nozzle when he came up behind me. 'You couldn't sleep?' he asked. My hands jumped so badly I nearly dropped the glass on the floor. I could feel his breath on my neck. I spun around to face him, the water sloshing in the glass and spilling a little on my hands. Then I realized. On top I was wearing a little silky white tank top with spaghetti straps that showed lots of belly. And on the bottom I was wearing a pair of skimpy white panties. I darted my eyes down nervously, almost panicky, to see what he was wearing. It was just his boxers. He caught me checking and smirked." Alex paused for a moment, stretching her arms above her head and smiling to her self strangely, almost pleased with herself. "Once I'd recovered from my surprise, the thought occurred to me that he'd probably been waiting up for me all night. That he'd sat up at the kitchen table, slapping himself awake, on the off chance that I'd come out from my bedroom at some point, and that when I did I'd be wearing something to make it worth his while. Maybe he did that every night. That man was nothing if not persistent. I admit that I was flattered by the idea of it: by the single-minded determination. Maybe part of me was glad that he was being rewarded so handsomely for all that patience and self-discipline. Out of all my nighttime outfits it was Roger's favorite. It might surprise you to hear me say this but I am well aware that my posterior, as they say, is one of my most attractive features. That and my hips. Roger makes sure of that. I'm not toned like a model, I realize, but I have a certain natural charm when viewed from the rear. It's no wonder Brian couldn't take his eyes off me at the beach today." She paused a beat and looked right at Elise. "Well, let's just say that this particular pair of panties suits me very nicely. And with the cropped top it really shows off my curves down below. I know that men like it the way I'm so dainty up top, except for these," she remarked, cupping her breasts from below, "and the way I'm so voluptuous below the waist. And the tank top, well, it's loose and silky but it clings to my chest in all the right places, not in an obvious way, more . . . sophisticated. But it's just the thing for showing a man a bit of nipple, when the mood strikes, and it's the easiest thing in the world for him to just reach underneath and grab a quick feel, or a long one. I like the way the spaghetti straps show off my collar bone and my small shoulders and arms." She ran her fingers across her collarbone and held out her arms in front of her and inspected them. "I'd worn the outfit to bed that night because I was extremely aroused (probably from being joked with and gaped at by Sergei after dinner) and I was hoping to entice my husband into sex. I hadn't masturbated for days because I was too afraid I'd start fantasizing about Sergei again. But Roger was too exhausted from running a bunch of stupid errands for the oil executive all afternoon and he asked for a rain-check. I was self-conscious to find myself wearing the outfit with Sergei, of course. But he'd seen me in lots of revealing clothes by then. This wasn't much different. At least that's what I told myself. Otherwise I would have taken my glass of water and marched straight back to Roger." Alex paused again, like she was lost in the memory. She had her elbows perched on the edge of the tub and her chest pushed forward. She looked down at herself in the bikini top. "But I didn't march straight back to Roger. I just stood there telling myself that it was all perfectly within bounds. I couldn't have known that Sergei would be in the kitchen at this hour, and I couldn't help it either. Roger should have enforced the house rules with him if there was something inappropriate about it. And now that we were here together it was perfectly natural to exchange a few pleasantries, even to chat a little, before I went back to bed. It was my job, in a way. It was my duty to be polite and welcoming to him." Alex gazed intently at the girls. They nodded their understanding. "I was too embarrassed to look at Sergei anywhere else except right in his eyes," she proceeded, "but I could see him looking at me all over. I concede that another woman might have been offended by those looks. But I wasn't anymore. I was well accustomed to it by now. I'd started to find it . . . refreshing . . . appealing even. 'Why couldn't you sleep?' he asked, after he'd had time to survey me, gruff in his usual way, but kind of sweetly too. 'Because you very thirsty?' I nodded. My hands were shaking. I was afraid I might spill the water all over him. 'What about you?' I asked. 'Why couldn't you sleep?' 'I dunno,' Sergei sighed, flashing his eyes a little and looking cute all of the sudden, maybe sad even. 'Maybe I also very thirsty.' We just stood there staring at each other. I was biting my lip and trying not to look down at him. Trying to hold his gaze. I had this crazy idea that if I ever let myself look at him the way he looked at me, up and down slowly, that I'd lose control of the situation. That I'd be consenting, somehow, to whatever came next. 'So what are we going to do?' he asked, finally. 'About what?' I replied. 'About being so thirsty,' he answered, looking deep into my eyes and leaning forward. I looked down, trying to avoid his gaze, and remembered that I had a full glass of water in my hands. I was brimming with tension and the whole scene seemed so ridiculous all of the sudden that I burst out laughing. Sergei laughed too. I looked at him and smiled and then, I don't know why, I brought the glass to my lips, with both hands, and started drinking it down, gulp after gulp. I knew he was watching. I knew he was watching my lips opening, and my neck tilting backward, and my throat contracting. I knew my nipples were hard. I drank that water straight down and then I stood there with the empty glass in my hand." Alex hesitated, remembering. "What happened next?" Elise prompted her. "Sergei just smiled at me," Alex continued, snapping back to attention, "not cocky this time, but more . . . appreciative. I felt a little tawdry about the whole thing but I was bloody well turned on! 'How about something for my thirst now?' Sergei asked, his voice real quiet, learning in toward me. I looked up at him. The insinuation was clear and I wasn't sure how to react. It was the closest he'd come, at that point, to making a real pass at me. After a second or two I took a deep breath, and turned my back to him, and started filling the glass for him from the nozzle. I don't know why it felt like such a transgression—I prepare drinks and meals for men every day—but it did. Maybe it was because I knew what he was looking at this time. The white panties were cut high and square across the bottom and they showed a lot of cheek. When the glass was full I turned around and handed it to him. He took it in both hands and tilted his head back and gulped it down. I was watching his throat contract and trying to keep myself from looking further down. But then I noticed that a stream of water was dribbling from the corner of his mouth, and down his chin, and onto his chest, and before I knew it my eyes were following it, all the way to his abs and waist. I was staring blankly at his torso, watching the tattoos dance. He finished the water and let out his breath, sighing with satisfaction. I looked back up at him. He knew that my eyes had been all over his body and I could tell he was pleased. And then . . ." Alex hesitated for a moment. Her eyes went vague. "What?" gasped Ellen and Elise together. "And then . . . he handed me the glass. I took it from him and just stood there holding it, not sure what to do next. Maybe I was waiting for his next move. Hoping for it. I can't be sure. 'You wash it now?' Sergei asked, with his cocky grin this time. I don't know what possessed me but I gave him a little saucy look, feigning irritation, and marched right to the sink and did it for him. My cheeks were red hot. I filled the glass with a little soap and water, and then I picked up the scrub brush, and then I started scrubbing. I washed that glass very thoroughly, let me tell you. After maybe ten seconds I started to feel vulnerable with my back to him—I was afraid he might press up against me from behind—so I turned to face him while I scrubbed. I'm not proud of the way I did it. But you should have seen his expression when I turned to him. He looked like a little boy who'd just been surprised with a puppy for Christmas. I started to enjoy my power over him. I held the glass at my waist, at my crotch really, and slipped the brush inside, and washed it slowly and thoroughly, and I watched Sergei the whole time, with my face burning from shame, and confusion, and desire. I wanted to see what he was seeing. He was looking everywhere but my eyes." Advanced Primatology Ch. 13 Part 1 Kate crawled out of the tent at first light, already fully dressed, and surveyed the wreckage of her surroundings. Everything looked strange. As far as she could see in every direction the ground was covered with leaves and flowers and large branches that the wind had torn from the canopy during the most violent parts of the storm. The trees were still dripping heavy drops and the ground was slick and dark. There were deep puddles everywhere and some of the rocks were covered with oozes and slimes. Mosses and fungi had sprung up seemingly overnight with the heavy rain. She noticed that Chad had secured all of the valuable gear under a heavy tarp where it would be dry and safe. Kate sat on her haunches and unwrapped a nutrition bar and wolfed it down, wondering when Chad had found time to arrange the tarp. She hadn't given a single thought to anything except getting inside the tent and getting out of her wet clothes after the storm caught them on their way back from field work last night. Not for the first time she felt grateful for Chad's foresight. Kate sat there for a few minutes listening to the sounds. It was only just before sunset and sunrise like this, she reflected, that you ever got a real sense of how every nook and cranny of the forest was teeming with life. The birds and insects and frogs were difficult to see during the day because they were so well camouflaged and because they kept so still and quiet. But at moments like this it was plain to the ear, and sometimes to the naked eye, that she was surrounded by a seemingly infinite variety of new and strange species. Most mornings when Kate listened to the birds, at least on this trip, she was struck by the sharpness and urgency of their interwoven calls, the males and females trying to locate each other and consummate their desires, their lusts really. It must have been something about the heaviness and stillness of the atmosphere this morning, though, with the mist still pouring off the foliage, because the cries sounded mellower and more subdued than normal, almost as if the birds were tired from a long, anxious night sheltering from the storm. She sat there listening for a long time before she looked out over the lake below and saw the clouds glowing like dull coals on the horizon. She turned instinctively in the opposite direction and saw the moon, just a thin sliver of blue rock, about to disappear behind the mountains. It would be the new moon tonight. Her thoughts drifted back to a conversation she had had with Karin and Jess in the restaurant of the hotel in Dar es Salaam, over breakfast, that first morning of the trip. It was only two weeks ago but it seemed like another lifetime now. She remembered apologizing to the younger women for being such a bitch that morning, and explaining that her hormones had gone haywire from going off the pill and trying for a baby with Brian. She remembered stealing glances at the undergrad table where Chad was flirting with the girls. Even then she'd been attracted to him. Karin told her how wonderful it felt when your hormones finally balanced out and you started ovulating again, following your natural cycle. She told her how powerful and confident you felt on your fertile days. Kate knew what she meant now. Kate had no idea what would happen after the difficult night she had endured with Chad— the heated argument, and the cruel words, and the long, intimate talk that followed. She smiled to herself remembering how she and Chad had used their hands and mouths to apologize to each other afterwards. She'd gotten a few hours of sleep at most. Christ Chad was a wonderful lover! He was the best she'd ever had, in some ways. He was maybe even better than her soon to be ex-husband. Chad was very good at the hard and intense stuff, of course, though she had to admit that Brian had a particular knack for just taking a woman, and using her, when the moment was right. But there was no doubt that Chad was more skillful at all the "extras" before and afterwards, the kissing and licking and fingering and sucking. It was something about the ardency that came more spontaneously to a young guy (it still shocked her sometimes how young he was!) and the thrill of finding himself alone and naked with an older woman, an adult with authority. She was someone he looked up to and wanted to please. He never seemed to tire of smelling her and tasting her and she loved the way he took his sweet time doing it. Kate stood up suddenly and arranged the small backpack on her shoulders. She didn't know what would come of last night, but she knew exactly what she wanted to do this morning. She wanted to say goodbye to Brad and Mahalia, and she wanted to do it alone. She was sure that she would see them back with M group sometime in the remaining two weeks of the trip, but she was also sure that once they returned to the group that would be changed irrevocably. She had something she wanted to say to Mahalia before then. She had something to ask her, even if she couldn't say what. Mahalia would understand. She strode into the forest, still dark with shadow, walking carefully and quietly so as not to awaken Chad. As she followed the trail to Brad and Mahalia's nest (she and Chad had beaten a pretty good path to the spot over the last few days) she replayed the details of the argument from the night before, shaking her head when she remembered how crazily she'd acted. "What do you mean I raped you!?" Chad exclaimed, the sweat still pouring down his chest in rivulets and his blue eyes blazing with indignation. "How can that possibly make sense when what you're angry about is that I did NOT come inside you!?" "I mean you raped me emotionally," Kate cried, Chad's sperm covering her breasts and belly in thick drops. "I mean that it was cruel! You wanted to hear me say it didn't you? You wanted me to ask you for it!" "Maybe I did," Chad replied, exasperated. "I don't know! I'm sorry! But are you actually saying that you're mad at me for NOT coming inside you and getting you pregnant?! Are you actually screaming at me for deciding NOT to knock you up with the baby of a 20-year old-college student from one of your classes? I mean, how would that look? How would you explain it to the other professors?" "I wouldn't explain fucking anything to anybody!" Kate seethed, shaking her hands at him. "I'd tell them that I had a one-night stand with some random guy I met in Africa and they should mind their own damn business! Fucking perverted old men! You'll be just like them some day, I bet!" "But the news will get out eventually, Kate," Chad countered, refusing to take the bait, Kate couldn't help remembering, and holding his hands out steadily in front of him to show her how reasonable and calm he was being. "You'll be fired, okay? There's no way they'll give you tenure when you are pregnant with a student's baby." "O yes they fucking will!" Kate hissed, getting madder and madder the more reasonably Chad tried to behave. "How?" "Because I'm going to write a fucking brilliant paper about our research with Brad and Mahalia," Kate ranted, fishing a bandana from her backpack and wiping the sperm from her breasts, "and it's going to be obvious to everyone that I deserve tenure on the merits! And because they aren't going to do shit about punishing me for fucking a student, and having his baby, because if they do then I am going to ruin all of them, including Brian!" Kate threw the bandana at Chad's head, scowling when he ducked to the side and avoided it, and went right on ranting, puffing her chest out and waving a long finger in the air, right in Chad's face. She looked down and saw that her nipples were rock hard and sticking straight out in front of her and she was glad because she liked the effect it made. She looked angrier and more threatening somehow: "I am going to MAKE Brian promise me that he will do EVERYTHING in his power to guarantee my tenure. And he CAN guarantee it! He's THAT important, and THAT famous. Do you know how much he brings in to the university in grant money every year? No way do they fire me if Brian backs me. And he WILL back me, because he owes it to me and he knows it. And because he's the last person in the world who wants people to start getting all ethical all of the sudden about indiscretions with students. To start talking about stuff like that in public." The more Kate said the more bewildered Chad looked. She couldn't blame him. She was dumbfounded herself. It wasn't until right at that moment that Kate realized how intricately she'd planned it all out, every detail, over the nights and days she'd been alone with Chad (maybe even before that!). It could really work! Somehow in her subconscious mind she'd worked out every detail so that she could have exactly what she wanted. And she KNEW what she wanted. It all depended on how convincing she could be when she told Brian exactly what was going to happen and exactly what he was going to do. And right now she wanted some things in her life very badly, and she felt very confident that she could be convincing! That was all it would take for her to get what she wanted: tenure, and recognition, and a big lab, and a beautiful baby! "But why do you want to have a baby with someone who's not going to be a good husband and a normal dad?" Chad pleaded with her, lowering his voice, and holding her by the shoulders. He looked straight in her eyes. "Why not just stay with Brian and have HIS baby then, if the baby's not going to have a real father anyway! I mean, at least if Brian was the father the baby would be better off financially." Kate changed her tone immediately. She recognized that Chad was really thinking it through with her and she realized that this was her best opportunity to make him see her side. Maybe all he needed was a little encouragement, a little self-confidence. "You're going to do great financially!" she beamed at him. "You don't need to worry about that one bit! It's obvious to everyone the minute they meet you that you are going to go very far in life." Kate scooted a little closer to Chad (they were facing each other kneeling) and dropped her hand to his thigh. "How much would you make playing in the MLS for a few years anyway?" "I don't know. It depends" Chad stammered, flustered by the change in mood, but relieved that the worst seemed over for the moment. Kate could tell that he was eager to please her if he thought it would keep her calm. She leaned forward and flashed her eyes to encourage him. "My coach tells me that there's some serious interest in me from some pretty good teams," said Chad, "but I'm not a superstar or anything, and it's not like the really rich leagues in Europe, so I'd probably start at something like 80k a year. It's not much, Kate!" "It's more than enough!" Kate beamed again, squeezing his thigh a little harder. "That will be terrific for you! You'll be self-sufficient in no time! You could even save a little bit. It will be really nice for you to have some money in the bank if you decide to go to grad school and be a professor like me." Kate could tell that the flattery was working like a charm, probably because she meant it sincerely, even if she was laying it on a little thick. She brought her other hand to his forehead and cleared the bangs from his eyes. "I make plenty from the university to support a kid. To support a few kids if I want them! And soon I'll be making much more. I'll get promoted to tenure next year, and publish my book, and then the royalties will start pouring in. I know they will. It won't be like with you and your mom. I promise." Chad still looked bewildered but Kate could sense that he was listening carefully. She knew it was the right moment. All he needed was a little reassurance! She drew her hands away from him and sat up straighter on her knees. She took a long, slow breath, looking Chad straight in the eyes and pouring as much conviction and warmth as she could muster into her deep, brown eyes: "And it's different making a baby with you because I have different expectations. With Brian all I ever wanted was to raise a child with Brian. But now that I'm not with Brian all I want is to raise a child by myself. Does that make sense?" Chad nodded. Kate took another deep breath and tried to think carefully. She knew she was about to play some of her best cards, and she knew it was a little bit wrong. Because in order to play those cards she needed to manipulate Chad, to draw on all the intimate knowledge she'd acquired about him in their brief nights of flirtation, and courtship, and mutual disclosure, knowledge about his weaknesses, and fears, and kinks, about the things he was most ashamed of. She knew it was wrong but she also knew that she couldn't stop herself either. She wanted something very badly, and she had some very desirable things to offer, and she was going to make sure that she got full value for them. She dropped one hand to Chad's thigh, casually, and brought the other to his chest, tilting her head to the side and flashing him her best heart-melting smile, warm and generous, but always with a little mischief at the edges: "And it's different making a baby with you because I love you in a different way than I ever loved Brian." Kate told him, holding his gaze steadily. "I'm not depending on you for anything, okay?" Chad nodded again, looking more lost than ever. "Well, I'm depending on you for one thing, actually" Kate teased him, letting her eyes fall to his crotch and moving her hand slowly to the back of his neck. She leaned forward and brought her mouth to his ear. "I'm depending on you for a hard fuck on my fertile day and a pussy full of sperm, okay? I'm depending on you for that as often as you can do it." Her hand was resting on his back now and she could tell he'd stopped breathing. She sat up higher until her womanly breasts were level with his eyes, sticking her chest out subtly until she had his full attention. "And if you give me that, tiger" Kate purred, sliding her other hand to his testicles, and caressing them tenderly. "If you give me a hard fuck on my fertile day and a pussy full of sperm, I'll give you anything you want." Kate could sense that she'd played her first card well, if the length and fatness of Chad's cock was any indication, and that it was time play her second. She drew her hands away slowly and sat back on her heels, creating some space between them. "I meant what I said last night. If you give me a baby, then you can have a home with me. Always. You can go pursue your dreams, and be big soccer star, or go to grad school in California or something, or whatever you want, and during the off-season, or the summers, or the holidays you can always come home to us. And we'll both love you. The baby and I will both love you." Kate finished and watched Chad carefully as he digested everything that had just happened, his expressions shifting. She could tell that he had been touched by her offer, and she knew that for a kid like Chad the vision of a home with her would be deeply appealing. Vut she also could tell that his head was seriously messed up from how quickly she'd just spun it. He was right on the edge. She couldn't blame him. The poor kid! "Then you're not just asking me to fuck you and make you pregnant!" Chad snapped, finally, his frustration evident. "You're not just asking me to fuck you!" he raved, waving HIS finger now and looking out of control. "You're asking me to be a father to a baby and I'm not ready for that! And you're not ready to be a mother either, okay! Because you are acting crazy. Just listen to yourself, Kate! You sound completely insane!" Of all the things that Chad might have said to her just then there was nothing that could have cut straighter to the bone. If Kate had a nickel for every time that a man had told her that she was acting insane in the heat of an argument—her lying father, and her lying husband especially—when they were trying to talk her out of some complaint she had, or some desire she had, that made perfect sense. If Kate had a nickel for every time she'd been told that she was acting crazy by a man—by a desperate, petty, defensive man who couldn't tolerate the truth—then she would be a wealthy woman. To be told the same thing by Chad at that moment triggered something overpowering inside her. "Of course I'm insane," she hissed at Chad, her eyes welling with tears. "Of course I'm insane for imagining that a guy like you, from your background, could be expected to take any responsibility at all for his actions! That he could even be bothered to visit his baby a few times a year! That I could ask him for that, at least! No, with guys like you, it's all about the thrill of using a woman, and knocking her up, and bragging to all the other losers back home about what a slut she is! It's just like that first night when you got me high and came inside me twice. I bet you'll really enjoy laughing about that one with the boys." "Oh, so now you're mad at me for the time that I DID come in your pussy!" Chad raved again, the hurt clear in his eyes, and the confusion too. "That's terrific. Because then you must not be angry at all about tonight when I did NOT come in your pussy! Jesus Kate. What do you want from me? You go crazy on me if I do what you tell me and you go crazy on me if I don't! How am I supposed to know what game you're playing, or what the rules are?" It wasn't the first time that Kate had been told something like this by a man either, and the fact that she could see some justice in the accusation didn't make her feel any less enraged. It made her feel angrier in fact, because she resented the sudden jab of shame in the pit of her stomach when it felt so much more fulfilling to be righteous. That ungrateful little prick! She was willing to give him everything! Everything! "Fine, Chad. Have it your way. If I'm so fucking crazy! I guess it's better then if you don't work in my lab this summer, and you don't live in my guesthouse, okay? I take it all back. You'll have to go home to mommy after all, I guess, because I WAS insane to think that there was any future with a guy like you!" Then Kate saw something that drained the sense of righteous indignation straight out of her, and made her realize how unfair she was being to Chad—how much she was unloading all of the anger and frustration she felt toward her husband and father on a boy who didn't deserve any of it, how much she was expecting from him when he was far too youthful to live up to her demands, how badly she was using him, in a way, to get through a tough time in her life. Chad's head was bent, and his shoulders were slumped. His chest was heaving. He looked smaller somehow, and more delicate. In all the times that Kate had been naked with Chad, and close to him, she had never before been struck so forcibly by the extreme youthfulness of his body. He was a powerful guy, no doubt, with broad shoulders and a barrel chest, but in many ways he still had the skin, and muscle tone, and proportions of an adolescent boy. When he looked up at her his eyes were red and swollen and his cheeks were shining with tears. Kate changed her tone right away, chastising herself. "I'm sorry, tiger," she told him, reaching a hand to his shoulder. Chad shook it off, angrily, and turned away from her. "I'm sorry, tiger," she told him, again, reaching both hands to his shoulders this time and pulling him toward her. "I mean it. It's all my fault. I'm being so unfair." Chad struggled with her for a few seconds but before long he relaxed and she was able to take him in her arms. She held him like that for a long time and Chad ended up telling her a lot of things. He told her how hard it was for him, because of growing up with his mother, to see a woman act so unpredictably and irrationally, and for a woman to depend on him for something that he wasn't adult enough to give her. And he told her how much it meant to him when Kate offered to let him work for her, and live with her, and maybe even have a home with her eventually, even if he didn't understand exactly what kind of home it would be. He told her it didn't really matter. Because if she could give him that, a place to come back to for affection and guidance in the unpredictable years ahead, and a friend to come back to, then he would try to give her what she wanted too. He would try his best. He would give her a baby if she wanted one that badly because it would good for their friendship and that would be good for him too. And he did think he could be a good father to their baby in the way Kate explained it to him, the way Chad wished that his father could have been with him. He'd visit the little girl or boy on holidays like clockwork and he'd be part of her life. But there was one thing he couldn't get past. Kate would be in a serious relationship with someone else at some point, no doubt about it. She'd probably even get married again. And what would happen then? Chad explained that he wasn't in love with Kate, exactly, but he kind of was. Just the thought of her with another guy made him feel insanely jealous. Advanced Primatology Ch. 13 Not for the first Kate was genuinely impressed by how smart Chad was, emotionally, for such a young guy, by how well he knew himself and how carefully he thought about life. She could see right away that he'd put his finger on precisely the conflict that would be most difficult for them to overcome if they actually went down the road she was proposing and tried to make a family of some kind. The funny thing was, she told him, that it wouldn't be a challenge for her at all to know that Chad had sex with other women, and serious relationships, and a wife and kids of his own someday. Chad couldn't understand why. She explained to him again and again that she simply didn't love him that way: "I love you more like, I don't know, not like a son exactly, because that would make it weird how much I enjoy having sex with you, but more like . . . a hot nephew from the bad side of the family who I never met before. That's it! Like a hot nephew from the sticks! With benefits!" Before long they were both laughing. "You're pretty smart for a dumb jock from the foothills, you know that?" Kate asked him. Chad nodded. "That's one of the things that I love about you, actually. Look, it doesn't matter if we make a baby together or not, okay? You can have a home with me any time you want, whether you knock me up or not. But if you want to have a home with me then eventually you are going to have to deal with me having sex with other guys, and falling in love with other guys, and maybe getting married again and having a baby." "I don't know if I can do that." "I know. It's okay. We don't have to worry about it just yet." Kate assured him, looking down at his face in her hands and smiling playfully. "It's going to be a long time, I think, before I want to have any cock inside me except this one right here." Kate reached down and took hold of him and before long their tongues were tangled together and they collapsed onto the sleeping bag in a heap. Part 2 Brian woke up with his head pounding and his back stiff from a long night of drinking and sex. He blinked hard a few times trying to clear the crust and film from his eyes and remember where he was. He looked up at the ceiling fan, and felt the hard boards beneath him, and realized that he was on the floor in the living room of the "women's cottage." He turned to his left and saw Elise sleeping on her side facing him, naked except for the sheet thrown over her lower half. He needed to break it off with her soon, but he had to admit that she was growing more and more appealing by the day. He let his eyes travel slowly down her long, thin frame, noting the swell of her breasts (it always surprised him how full they were) and the slope of her hips (she could really move them!) and that taut belly, with just a little flesh at the edges, leading down to those delicate blonde curls (he pulled the sheet down to get a clearer view). He had a new appreciation for her, and not just physically, after what she'd pulled off in the hot tub with Ellen and Alex last night. Persuading Alex to tell them that incredible story about her temptation by Sergei, and to tell it very well! Elise had just the right combination of smarts, and good looks, and twisted imagination, and a genuine love for the fine arts of seduction, and manipulation. He remembered sliding out of the hammock after Alex finished her story, and finally went to bed, and slipping into the hot tub and taking Elise in his arms. She wrapped her legs around him tight and laughed, delightedly, as he pulled her bikini bottom to the side and forced his cock inside her. He knew that Elise would be wet and ready and he wanted to do it fast and rough so he could still surprise her, and knock the wind out of her, for those first, few, excited gasps. They were fucking feverishly before Ellen even had time to get her head around what was happening. He knew she'd like it. He knew that it was how all three of them wanted the story to end—with Sergei just taking Alex (just taking her for Christ's sake!) so she didn't have a choice anymore. So it was already happening before she could even say or do or think anything about it. So that her mind went blank, and her body took over, and she gave herself to Sergei. He looked over at Ellen, and grinned at her, knowingly, while his eyes roamed all over her. Jesus she had a cute body. She grinned back. He reached out, and grabbed the back of her head, and pulled her face to his, kissing her roughly. Brian's thoughts were drawn back to the floor of the women's cottage by the sensation of a second body, to his right, suddenly squirming against his. There was a split second when he rolled over to appraise Ellen's naked form, and maybe feel her up a little before she awakened completely, when his heart stopped and his head went cold. Ellen was turned away from him on her side and her long, wavy, reddish hair must have been thrown forward over her shoulders in a way that (from the back) made it seem much shorter . . . about shoulder length . . . . He saw the freckles . . . the dainty shoulders . . . the shapely backside beneath the thin, white sheet. He felt a sense of dread in his stomach and a jolt of electric current straight to his testicles. It was only the flash of an eye before he realized that the woman next to him was much taller than Alex's diminutive 5' 2", and before he remembered some of the details of his little threesome with Ellen last night. Oh well. It was probably for the best. Besides, he remembered, Ellen had a truly luscious ass (though it couldn't hold a candle to Alex's) and she was an absolute fiend for cock. He remembered the sight and feel of her when she was on her knees on the floor in front of him while he penetrated her long and slow, and then fast and rough, and then long and slow again, throwing her a little twist and grind at the end of his thrusts until she was raising her tail so she take him deeper. They must have fucked for 30 minutes like that! He remembered Elise pressed up against him from behind, scratching his chest, and caressing his jewels, and pouring filth in his ear. "O god! O god!" Ellen groaned, her buttocks shaking as Brian angled his cock upwards and fucked her a little sharper. "I bet that's how Alex would have sounded with Sergei," Elise murmured, sliding her sweaty breasts against him. "If he hadn't blown it. If he'd just taken her like a real man would have. Like she was begging him to." "O fuck! O fuck me!" Ellen gasped. "I bet that's how she would have looked too," Elise teased, "if he'd just taken her from behind. I don't know how he resisted. When she was alone with him in the kitchen in her tiny white panties? When she bent over the kitchen counter to put the glass away? What was he waiting for, an engraved invitation? How hard could it be to just lay her out on the counter and fuck her like she was begging for. Like a piece of meat!?" Brian groaned with lust as he pictured the details of the scene. He slapped Ellen on the hips, and signaled to her, and with a few deft motions he arranged her on her back on the coffee table in the center of the room. He smiled down at her and fed her his shaft. "OOOOooooohhhhh god, that's good!" Ellen whined, alluringly, through her nose. Brian loved it when women made embarrassing noises like that in the heat of being fucked. He watched her breasts and stomach jiggle as he squatted on his knees in front of her, his legs spread wide, and gave her a serious pounding. Before he knew it Elise was lying on her back on the coffee table next to Ellen and looking up at him, grinning, while she fingered herself slowly. "Close your eyes, professor," she teased him. "Close your eyes, and listen, and I'll bet we can convince you that it's Alex you're fucking." Brian did what she told him. He got the best look yet at Alex's phenomenal little body when she climbed out of the hot tub at the end of her story, saying good night to the girls and picking up a towel from the floor to dry herself. He was still in the hammock, pretending to sleep, and when she bent forward he got a long, clear view of her breasts as they hung toward him in the plaid bikini, swaying a little as she felt for the towel, and then again, in a different way, when she stood up quickly. She threw the towel over her head, deftly, and held it behind her back, and dried herself. Brian nearly groaned out loud as he watched her shimmy her shoulders, and snap her hips, just briefly. It was subtle, for certain, but it was also a clear signal if you knew what to look for. She did it in a way that left him little doubt, if he still had any, that she was a firecracker in the sheets. Her husband Roger was a lucky man. Brian was hard already (he was afraid that Alex might be able to see him beneath the towel) but when she shook for him like that, exposing her whole front to him, he nearly came in his shorts. And not just because of how fine Alex's little body looked, but also because she was looking at him the whole time, right in the eyes. He had the fisherman's cap pulled low over his face but he had a funny feeling that she knew, somehow, that he was looking right back at her. "Well, you kids have fun," Alex chimed, sweetly, turning away from Brian and giving him a direct view of her curves from behind. "But be careful with the fire, okay?" Alex picked up a long metal poker from the wooden barrel next to the hot tub and bent over to stoke the flames. She was definitely right. Her posterior was one of her most attractive features. Brian watched her buttocks tense and strain as she jabbed at the logs with the long metal rod. He wished he could pull out his phone, and snap a couple photos, and take them back to his room later and masturbate furiously to the spectacle of that voluptuous rear end, so round and meaty, on such a tiny woman. When she was finished she stood up, taking her time, Brian noticed. "Well, good night kids," Alex chimed once more. "And don't do anything I wouldn't do!" She looked directly at Brian, her eyes seeming to pierce through the shadow cast by the brim of his hat. Then she winked at him, just once, and spun on her heels and sauntered from the room. The sound of Elise's voice brought him back to the present. She was kneeling on the floor at Ellen's side and purring in her ear now as Brian fucked her hard. He'd picked up the pace, unconsciously, while he was remembering the scene with Alex. "Just do it, Ellen. He'll love it!" "No! It's too weird!" Elise laughed. "O come on, baby! Please do it? For me?" Elise leaned forward over the coffee table, and reached out her hands, and brought her fingers to Ellen's engorged nipples, tweaking and twisting and fondling them hard as Brian started thrusting like a madman and Ellen's stomach started quaking harder. Elise leaned forward further and gave Ellen a hot, wet kiss with lots of tongue, loud, so Brian could savor the sound of it. "Do it! He'll love it!" Elise pleaded. "Oh Sergei," Ellen cried, doing her best imitation of Alex's posh accent. "O fuck me, Sergei. O fuck me in my bed. Just take me, and fuck me like a piece of meat in my husband's bed and cum inside me!" Elise was right. Brian did love it. It was just the thing to complete the sick little fantasy in his head (in all of their heads!) and coax him right over the edge. He closed his eyes and enjoyed the delicious sensation of Ellen's slick, tight, twenty-year-old pussy as his testicles contracted, and his stomach muscles clenched, and his mind went blank. Part 3 It didn't take long for Kate to find Brad and Mahalia. They were at the usual spot, doing the usual thing. The cool, crisp mornings were definitely their favorite time to copulate and Kate could understand why. Watching them now she could sense how intimate and familiar they had grown with each other during their "safari" together. She watched Brad wander over to Mahalia and start thrusting into her from behind, almost casually. He was munching quietly on a piece of fruit and looking thoughtfully into the trees above, scouting for birds, or interesting things to eat, or who knew what else. She watched Mahalia barely stop what she was doing as she raised her backside so that Brad could mount her. She was using a stick to hunt for ants in a large mound she'd just located, and when she withdrew the stick from the earth, crawling with delicious insects, she flashed a big, toothy grin in Kate's general direction. Kate knew it wasn't intended for her but she couldn't help laughing anyway. Mahalia looked up. She was always curious when Kate (who was among the quietest of humans, she supposed) made any sudden sounds. Kate and Mahalia looked at each other, silently, while Brad finished thrusting and turned his attention elsewhere. She couldn't help noticing that the sense of urgency to their mating during those first few days had faded somewhat by now, and she felt a pang of jealousy as she realized that this was probably because they'd copulated successfully many, many times while Mahalia was at peak fertility. They were carrying themselves like two primates who know that they've done their job well. Kate was sure they were pregnant. And she was sure that there would be a close bond between them even when they returned to M group, even if they never had the chance to slip off together again and make another baby, before Mahalia grew too old and feeble and lost her status in the group. Kate tried to remember what she had wanted to ask Mahalia. But she couldn't. Looking into her deep, round, expressive eyes she was struck again by how little there was in common between them, when you really got down to it, even though genetically they were almost identical. They shared 99% of their genetic material but they existed in completely different worlds. What advice could Mahalia possibly have for a woman like her, a woman at a crossroads? How could she know whether Kate was capable of raising a baby on her own, and whether Chad was the right male for mating? And then it hit her! It was so simple! She didn't need a mate. That was one of the most important ways that she was different than Mahalia, in fact, when you thought about it from the right perspective, when you focused on the all-important question of what strategies for reproducing each female could pursue. If Kate wanted a baby she could make it all by herself. Well, she could make it all by herself with a little help from the neighborhood sperm bank, and a doctor she trusted. She knew some very nice women from the fertility clinic at UNC (one of them taught her Yoga class on the weekends) and Kate felt a rush of excitement as she pictured calling her, and having coffee maybe, as soon as she got home. Kate remembered back to the first day in the cloud forest, when she and Chad stumbled upon the mother chimp and her baby. She remembered watching the mother split nuts with a heavy stick and feed them to her infant, one by one. Kate knew she could do it! Yes, it would probably be better for the child to have two parents who loved each other, and helped each other. She couldn't deny it. But her child would have so much all the same! It would have a committed, loving, capable mother, and it would live in a stable, first-world country, in the upper middle class, and it wouldn't ever have to worry about going hungry, or dying of malaria, or even going to bed alone. That was miles better than what most kids in the world had these days! It was miles better than what most kids in the United States had, for crying out loud. It was lots better than what Chad knew from his childhood, for example. Kate turned on her heels and walked briskly back to camp. She wanted to wake Chad up, as soon as she could, and tell him the news. Part 4 Brian was doing yoga on the lawn near the lake when he saw the first flare go up in the mountains. He watched it rise in the air and arc toward the lake, leaving a long green trail of smoke behind it. He didn't know what it meant at first, until he remembered the plan. Each of the three search parties was supposed to send up a flare at 9a.m. sharp on their fourth day in the mountains. A green flare meant that one of the pairs was coming home that day. Yellow meant they were staying. Red meant emergency. Brian wracked his brain trying to remember which pair was assigned to that particular peak, the one farthest to the south. He tried to picture the map when he'd spread it out on the coffee table for Kate and organized the whole thing a few days ago. Now he remembered. He was pretty sure the flare was from Jess's camp, though he wouldn't swear to it. She was a hot little number, that one! Maybe he should hang around a little longer. Kate would have a good laugh if she could see me now, thought Brian, as he eased into downward dog, still picturing Jess. Kate was always trying to convince him to do a few stretches with her whenever he complained about his stiff back, usually after a long flight home (and a long weekend of adulterous sex, often enough). He'd learned more than a few stretches over the years and when he woke up this morning his back was stiff as hell. But that wasn't the only reason he wanted to fall back on the comforting routine of the exercises he'd learned from his soon to be ex-wife. The truth was he was missing Kate terribly. Ever since Alex came to the conclusion of her story last night, the part where she told the girls how hot it felt to have the man you loved put a baby inside you. How it was the hottest sex ever. Brian knew she was right. There was no point denying it. It wasn't until that moment that he'd been struck with the full force of everything he'd given up with Kate, of what he'd traded for those nights of hedonism and excess like the one he'd spent with Elise and Ellen. Brian was in cobra pose when he saw a second flare go up, from Karin's camp this time, he was pretty sure. That settles it, he thought to himself. He was definitely leaving for Geneva this morning. If he got lucky with the schedules at the airport he could still be there in plenty of time for the award ceremony. Brian wondered if any of his recent conquests would be at the hotel when he arrived. He felt his balls stir as he remembered that conference in Amsterdam last year, the one where Karin delivered her first paper to an international audience, and where they shared the long trans-Atlantic flight together, drinking and talking the whole time. There was definitely a little chemistry between them. And she was a smoldering specimen of womanly flesh, no doubt about it. He remembered walking Karin back to her hotel (a much cheaper one than his) after the celebratory dinner, with his hand on her waist. At the door to her room he leaned in to kiss her and she was just a little too slow turning her cheek to the side. The prospect of sharing the woman's cottage with Karin, and with Elise too for that matter, had trouble written all over it. If the three of them ended up alone together there was no telling what might happen. And if things did happen it would screw up his plans to get therapy from Karin's husband, who was one of the few shrinks he really trusted (although from the stories that Elise told him about Karin fucking Chad with her fiance's permission maybe it was him who needed therapy!). Roger was just starting to think that maybe he should stick around for a while, and see where things went with Karin, when he heard Roger's boat approaching. He knew it was stupid but he decided to regard it as an omen of sorts, confirmation that this was the fated time to part ways with Kate, and the others, for now. He stood up and walked over to Roger as he sprang over the side of the boat, spryly, and started securing it to the pier. "I've got a favor to ask you old friend," Brian told him. Advanced Primatology Ch. 13 Roger rolled his eyes. He'd heard it all before. It took no time at all for Brian to persuade him to ferry him to the village so he could arrange a car to the airport. Just like always. "C'mon, mate! I'll pay you well." Brian encouraged him. "And you could use a little extra cash, I bet, for when you and Alex get pregnant." As soon as Brian saw the look in Roger's eyes—that glimmer of suspicion—he knew he'd said too much. "Maybe I can do it," Roger mumbled, embarrassed. "But first I need to talk with my wife." Part 5 Kevin was cooking breakfast when he saw the green flare go up from Karin and Courtney's camp. Jess saw it too. She was organizing the packs for another day in the field and Kevin was watching her closely, still not quite able to believe his luck. It wasn't that he'd hooked up with Jess. He hadn't. Jess had rejected him in fact. Kind of brutally. But what he'd gotten from her in the end was better, somehow, if that was even possible, than if he'd scored with her in the tent. It was better because if Kevin had scored with Jess in the tent then she would have been cheating on her boyfriend. That was why she rejected him, last night, when they were talking on the floor of the tent, facing each other, like usual, and Kevin finally worked up the courage to lean in for a kiss. She stuck out her hand and pushed him away. Kevin wanted to die of embarrassment, at first, but then Jess explained to him that she liked him a lot, and she wanted to be with him, but she needed to get her head together first. She needed to break up with her boyfriend, at the very least, before she had sex with anyone else just yet. Kevin still felt a little hurt, and he acted like a real mope at first, he had to admit. He was thinking that the idea of cheating on her boyfriend sure as hell hadn't stopped her from spreading her legs for Chad, and his big cock, back at the camp last week. Jess kept asking him what was wrong. Probing him. She was telling him she wanted to date him when they got back to Chapel Hill, maybe! She was giving him her number: typing it right into his trusty phone with the sweet speakers that he'd used to play his music for her, and win her heart. What could possibly be wrong? They ended up having a conversation about Chad, and about why she'd cheated with him, and Kevin was happy that they had. Because that was something he needed to understand, and get his head around, if there was every going to be anything serious between he and Jess, which he hoped there would be. Was it all about the big cock, and the broad shoulders, and the whole alpha thing, he asked her, finally, once he'd worked up the nerve. "I don't know," Jess laughed. "But you guys are all the same, you know that?" "What do you mean?" "You're all obsessed with big cocks!" Jess teased him, smiling. "Sometimes I think you should all just go off on an island somewhere and jerk off for each other and be done with it. It's tiring the way you're always asking us ladies questions about it the way you do!" Kevin laughed, despite himself. "Besides," Jess continued, "from what I can tell you have a very nice cock. I've seen it plenty of times through your running shorts in the tent and it looks like it would do the trick just fine. It looks well above average, okay?" Kevin kept on laughing, his face bright red. "And plus, I know from your massages that you're going to be very good at all the really important stuff! The kissing and caressing. You've got those bass player fingers on those big hands!" Jess reached down and took his hand in hers and tangled her fingers through his. Kevin felt himself stiffen. "Now go to sleep," Jess snapped, playfully. "And turn away from me, okay? I don't want you poking me in the ass again with your big boner all night." Kevin was lost in the memory when he heard the sound of Jess firing the flare, right next to him, from the plastic pistol. It was the green flare. They were hiking back to camp today. Part 6 Kate and Chad were deep in conversation when they saw the green flare go off from Karin and Courtney's camp. She'd just told him all the details about her new plan. About meeting with her friend the fertility specialist, when she was back in Chapel Hill, and about visiting a sperm bank, and selecting a donor, and about getting pregnant without him. "You're off the hook, kiddo," Kate beamed at him. "Isn't that great?" Chad looked utterly and completely lost by this latest in a long series of mood swings on Kate's part. By her bold, new plan that she'd already worked out, somehow, to the last detail, while she was off in the forest for like an hour! 'Screw it,' Kate thought to herself, when she noticed how frustrated Chad seemed, and when she felt tempted to take pity on him again and explain it more patiently. 'Women are changeable creatures. They have to be in THIS world! That's just something that Chad is going to have to get used to if he wants to be with me any more!' Kate felt so energized by her decision! She knew it was right! Chad would come around in the end. At least she hoped so! Because she knew she wanted to be with him. She wanted it now more than ever, in fact, in a funny way. It was something about the fact that she wasn't depending on him anymore to knock her up, and be a father, or any of that stuff. It allowed her to experience all over again, somehow, just how raw and powerful her attraction to him was. Her sheer, primal, physical attraction to him! She loved being with him, and sleeping with him, and kissing, and fucking him and all of that stuff and she was thrilled at the idea that now she could just relax and enjoy the sex with him, without any of those stupid strings attached that she'd dreamed up in her head. She tried it to explain it to him, all at once in a big rush, and it came sounding a little crazy at first. "The great thing is that we can just relax and have sex with other now without worrying about all that pregnancy and fatherhood garbage! We can just relax and fuck! I mean, in a way it wouldn't really matter now whether we got carried away and you came inside me. Right? I'm going to be pregnant either way, whether it's your sperm or not, so it's not like you need to take any particular responsibility for an egg that happens to have been fertilized by one of your little seeds. If we're having a good time, and it feels good, and you get carried away. Does that make any sense at all?" "Not exactly," replied Chad, trying to keep his cool. Kate knew he was confused, but she knew he was turned on too. "Look Chad, I want a baby, okay?" Kate told him. "And I'm not going to just sit in my bedroom and wait for the right man to come along to take me away in a magic carriage and fertilize my womb, okay? And I'm sure as hell not going to go through the horror show of actually filling out a profile on one of those god forsaken websites and trying to meet the 'right man' or any of that crap! The man who'll be willing to go on a few dates with me, and then sleep with me maybe, and then give me what I actually want. Which is not a man, okay, but a beautiful baby! And I'm not going to go to a club in a hot outfit and lure some hot, young stud back to my house and just fuck him dry, and never tell him anything. And you don't seem to want to get me pregnant either! So what else am I going to do? I'm going to go to the sperm bank, and read through the files, and do the whole thing rationally. I'm going to pick a donor who seems like he has the right qualifications for the job and then somehow or other (I need to ask my friend about the details) I'm going to get injected with the donor's sperm and I'm going to have his baby. Except it will be MY baby. That's going to happen with you or without you, I'm afraid, because although I really do care about you a lot, genuinely, I am also a 35-year-old woman and I have to get on with my life. Does that make sense?" "Yeah," Chad nodded, almost laughing out loud. "It kind of does, actually, in a weird way." Kate smiled at him warmly, remembering how charmed she'd been by his smile (so boyish and so deeply handsome all at the same time) at the welcome reception that first evening of the trip. And then the flare went off. A green one. They watched it trailing through the cloudless sky. They both sat on their haunches for a few minutes, silently, and waited for the second flare. Another green one. "Decision time, tiger," Kate told him, not missing a beat. "Are we going to stay in camp another day and get the gear in order, and maybe relax a little after? (she dropped her head to the side and smiled at him as she added the list bit, in a huskier tone). Or are we going to break camp right now and head back to the lodge today. If we hike straight through all day we can be there by sunset." Kate smiled to herself, and to Chad, as she watched him puzzle things over. She couldn't explain it. It was the damndest thing. She couldn't make the decision herself, but she felt completely in control. She was looking at Chad in a way that left no doubt that she would agree to whatever he decided. But it didn't matter what he decided. Because it was her choice, even if Chad made it! It was her choice if they went back to the lodge, and it was her choice if they stayed in the mountains. And it was her choice if they stayed in the mountains and they fucked all night, and it was her choice if they stayed and they did not fuck once. It was her choice if Chad came inside her, and gave her a baby, and it was her choice if he didn't. It didn't matter! Kate watched Chad as he dropped his eyes and looked her up and down slowly, and then up and down again. She felt the hairs stand up on the back of her neck. It had been a while, it seemed like, since he looked at her that way. Like she was piece of meat and he was trying to figure out how to cook her for dinner. Kate knew that she could use a bath, and she knew that her white linen shirt and yoga pants weren't the most flattering outfit she ever wore. But Chad knew all he needed to know by now about her womanly curves, and how badly he desired them, and he could make out just enough of her shape through the outfit to remind him if he'd forgotten. And if Kate knew anything in wide world at that instant she knew that she had a beautiful body, and that her face was radiant. "Let's stay," Chad said. "Let's stay and get some work done. And maybe relax a little after." Kate loved it when he did that. When he flashed his eyes. "But can we do one thing first?" he asked. "What's that?" "Can I go to the stream and take a bath? I'm covered with dirt, and sweat, and a bunch of other stuff." Both of them laughed. "Yeah, I know," Kate chided him, "I think I can smell that other stuff. I think it's all over me too." "Then maybe you can join me?" Chad drawled, dropping his head to the side. "Yeah?" Kate asked. "Yeah." "Okay," Kate agreed, blushing despite herself. He had a real knack for surprising her with those smooth come-ons. "I'll just grab my suit." "That's alright," Chad assured her. "I'll just grab some towels and we can head off. You don't need a suit." "Yeah?" "Yeah. I'm not bringing one either." "Okay," Kate consented, blushing deeper red. "Then it's a date." She walked over to the tarp, and pulled back the corner, and found the little flare pistol in the plastic case. She loaded the yellow flare and fired it, high toward the lake. Part 7 Elise had been sitting in the hot tub for close to an hour but she was still fuming. Professor Phare was such a bastard! She couldn't believe that he'd dumped her again, not even bothering to say goodbye this time, really, before he boarded the boat with Roger and left for the nearest airport. After everything she'd done for him! After she'd seduced three of the other co-ed girls for him, just like he'd asked, and arranged threesomes with them and everything! That ungrateful old shit! The only consolation was that Alex was just as pissed off at her husband Roger for agreeing to take Brian to the airport for a hefty fee. She was so angry that she marched right over to the women's cottage as soon as Brian left (as soon as she finished screaming at him!) and invited everyone in the living room—Elise, Karin, and Ellen—over to the main lodge right away for vodka martinis on the back deck and maybe the hot tub afterwards. By this point all of the girls had consumed several drinks each. Strong ones. But there was a bottle filled with vodka martini mix standing beside the tub in an ice bucket and none of the ladies had any intention of stopping any time soon. All of them had a reason to drown their sorrows tonight, Elise reflected, and they were all glad for the company. Elise was seated directly across from Alex, with Karin on her left hand, and Ellen to her right. She could tell by the way that Alex kept wrinkling her brow that she was replaying her argument with her husband, just like Elise was replaying hers with Brian. "What's wrong with me?" Elise blurted out suddenly. "Why did Brian leave, again, when it was just starting to get good between us?!" "Do you really want to know?" Alex asked, taking a sip of her drink. "Yes!" "Because you're too young for him, dear!" Alex declared, a little abruptly, true, but with evident warmth. "It's that simple. And because he's probably still in a lot of pain from his divorce with Kate. They were married for a decade, and losing her is bound to hurt." "I know all that!" snapped Elise. "But that was as true yesterday as it is today. So what changed?" Alex watched her carefully, trying to judge her mood. "Perhaps the thrill was gone," Alex suggested. "You had sex last night, I suppose, after we left the hot tub?" "Yeah. So?" "Well, perhaps it was all just a little too easy for him, my dear. A man like Brian likes a bit of challenge now and again, I suspect." Elise couldn't believe the nerve! To call her out for being too easy like that right in front of the other girls. So calmly! "Should I have played hard to get, then," Elise asked, her voice dripping with sarcasm. "Like you did with Sergei?" "Who's Sergei?" Karin asked. "Oh just some ripped Russian helicopter pilot who Alex had the hots for!" said Elise. "I told you about Sergei in confidence, my dear," Alex reminded her. "I know. I'm sorry," Elise replied, hurriedly, rolling her eyes. "Oh don't mind Elise," Ellen jumped in. "It's just like she said. She's just in a bitchy mood because Brian left this morning without warning her." "O shut the fuck up, Ellen." Elise spat. "You're just in a bitchy mood because Courtney found out that you fucked Brian and sucked his cock last night and she's all jealous and angry." "Actually, she's more upset about the fact that I fooled around with you," Ellen retorted, coolly. "I didn't think you had it in you, I have to admit. Making out with me and playing with my tits like that. But I guess there's nothing you wouldn't do to please your precious master Brian, is there? Too bad you couldn't keep him hooked, though." "Girls, girls, stop it please," Alex implored. "Why do YOU think that Brian left, Elise?" "I don't know!" exclaimed Elise, her frustration audible. "I mean, I know he wanted to be at this award ceremony in Geneva tomorrow, though he hadn't mentioned it in a while. But then this morning when he saw Karin's flare go up he decided to leave all of the sudden." She turned to Karin, eyeing her curiously "He said something really strange, actually." "What's that?" asked Karin. "Well, we were arguing, and I was demanding an explanation, and he said, 'Listen Elise, the idea of Karin and I sharing the cottage tonight has trouble written all over it.' Now what do you suppose he could have meant by that?" Karin shrugged her shoulders. "I was thinking that maybe it had something to do with your little bucket list with your fiancé. You know, the one where he gave you permission to fuck Chad. I was thinking that maybe he gave you permission to fuck Brian too." "I think that's enough, Elise." Karin rejoined, her voice rising. "I think you should stop right there." "O don't worry, Alex knows all about the fact that you fucked Chad non-stop for two nights before you left for the mountains," Elise continued, yanking the bottle from the ice bucket and pouring herself another martini. "We had quite the little chat last night, didn't we girls?" "Well, we did gossip about you a bit, it's true," admitted Alex, "though I'm sure you can count on all of us to be discreet. Right ladies?" Neither of them responded. "Right young ladies?" asked Alex, taking a sharper tone. They both nodded. "Actually, since you know about Chad and I," Karin began, choosing her words carefully, "then maybe I could ask you a question. As a married woman." "O yes, please do," Elise encouraged her. "Mrs. Roger Briggs is just full of lessons about marriage and fidelity and all that. She's a paragon of virtue." "Just ignore her, Karin," said Alex. "It seems that young Ms. Rice over here is determined to drag everyone down to her level this evening." "O sure," Elise hissed, "Like I'm the only one who's feeling abandoned and frustrated tonight. It's not like precious husband Roger decided to spend another night away from his precious wife here, and on her 'special' day too!" "What special day?" asked Karin. "Elise, my dear, I will ask you again to respect my confidence. As I will respect yours." Elise shrugged and nodded, looking contrite enough to appease Alex for the moment. "What was your question, Karin, before you were so rudely interrupted," asked Alex. "What do you think about my arrangement with my fiancé?" Karin asked straight away. "What do you think about him giving me permission to sleep with other guys? The guys on my list?" "Well," Alex began, looking serious and thoughtful. "If the two of you have discussed it and feel comfortable with it then I suppose it could be healthy. Especially if you're honest with each other. I'm not going to sit in judgment. But I must say, my dear, I think you're playing a very dangerous game. I'd be very careful about not playing it beyond that one time. And I'd be absolutely clear and honest with your fiancé about what happened. Well, not entirely honest." "What do you mean?" "It occurs to me that your fiancé will probably want to hear certain . . . details about your time with Chad." "Yeah?" "I'd give him the edited version, if you know what I mean. Men have fragile egos, Karin, and they are easily bruised. That kind of thing can be poisonous for a marriage. I think you should tell him that it was an interesting experience, and you're glad that you tried it, but that it scared you." "Is that what you did when you told Roger about Sergei?" Elise needled her. "Did you leave things out to spare his feelings?" "Yes, I did." "Like what?" "Like some of the details about how attracted I was to Sergei, and why." "What about your little fantasy session in the bathroom after he tasted your sauce?" Elise mocked her. "Did you leave that out too?" Alex gave her a withering look, warning her clearly, with her gaze, that something more serious would happen if Elise pressed her further. She wasn't dissuaded in the least. "That's the part of your story that I find the least believable, actually," Elise commented, almost casually. "That you only masturbated one time to the idea of being with Sergei. How can that possibly be true?" "I'm going to ask YOU a question now, Elise," Alex replied, her voice shaking a little, "and I'm going to do you the courtesy of asking it very directly." "Alright," Elise shrugged. "Fire away!" "What could have possibly happened to a smart, attractive, privileged girl like you to turn you into such a manipulative bitch?!" Advanced Primatology Ch. 14 Part 1 By the time Kate looked up from her notebook it was twilight and the moon had already cleared the horizon. Her stomach dropped when she saw it: huge, dark, and perfectly round, looming above the lake. Kate knew what it meant. She knew beyond the shadow of a doubt. She could tell by how full and ripe and sensitive her breasts felt, and her lips, and by the fact that her panties felt cool against her skin because she'd been wet practically all day and they were soaked by now, not to mention the way her stomach kept doing flips. And she could tell by how calm and fearless her thoughts had been too. Her post-doc Karin had told her once that a woman felt more creative and energetic when she went off the pill and followed her natural cycle and now Kate finally knew what she meant. She flipped through her notebook, shaking her head in disbelief. There were so many pages filled her with her tiny, indecipherable scrawl, and every sentence and idea was clear as a bell. She knew she had the draft of a brilliant article and she knew that it would make her career. Kate stretched her arms above her head and sighed deeply, trying to piece together the events of the last ten hours. The day had passed quickly, in a blur of activity, after she and Chad made the decision to stay one more night in the cloud forest and then return to the lodge at daybreak. She smiled remembering their conversation. They both talked a good game. They told each other all the right things to keep each other from getting too anxious and freaked out to actually follow through: that they were staying in order to get the gear packed correctly, and to make sure that all the data and video and notes and such were in proper order for the long hike down the mountain. But they both knew why they were really staying. They both knew that they wanted to have one more night alone together in the tent where they could talk and tease and touch and screw each other for as long as they wanted, and as loud as they wanted, and in whatever position happened to cross their mind, without worrying about whether the postdocs Karin and Jess might hear them in their tiny bedrooms in the women's cottage, or worse, whether Kate's soon to be ex-husband Brian might still be at camp and they'd need to cool it for a while to keep up appearances. Kate laughed out loud remembering how Chad sweet talked her into taking a "bath" with him at the stream after they finished planning. They walked slowly and quietly through the forest, both tired from a long night of arguing and sex, and when they came to the grassy slope near the bank of their favorite swimming hole they turned and faced each other and stripped out of their clothes, slowly and quietly too. She unbuttoned her loose white shirt and slid it from her shoulders, Chad's blue eyes surveying her hungrily. She shimmied her hips and bent forward to slide the black yoga pants from her hips, then down her long, lean legs. She stood up straight again and unfastened her bra, Chad's eyes flashing as her ripe breasts spilled forward. He stepped toward her right away, like a reflex. Kate sat on her haunches and stared vacantly at the moon, savoring the details of the morning. Before she knew it she had her tongue in his mouth and his cock in her hand and she was stroking him gently, feeling him swell. She wrapped her hand around him tight and pulled him toward the water, backing up slowly as she gripped him by the base. She shivered with pleasure remembering the moment when they finally stepped under the falls and the cold water hit them . . . the raw surprise . . . their skin steaming. She stepped closer to him, into the circle of his heat, and held the little bar of soap in her hand and brought it to his crotch. He smiled down at her, so pleased with himself. She loved it when he looked at her that way. Like she was a fine meal spread out for him on a big table and even he couldn't quite believe that he was about to sit down and devour it. They stood under the waterfall for a long time while they kissed and explored each other's bodies, Kate soaping and caressing Chad all over, slowly and carefully, covering every inch of him in thick lather. She paid special attention to his cock, of course. His scepter and crown and heavy round balls. Jesus, she blushed, remembering the smug grin on his face as he looked down and watched her practically worshipping his cock, her breasts swelling and her eyes filled with fascination and lust. It must really get him off, she thought, shaking her head. She still couldn't believe how quickly this punk college kid had seduced her. All those careful strategies he'd used to make her feel comfortable with him, and friendly toward him, and hungry for his body, getting closer and closer, until she gave him what he wanted, what girls always gave him: her whole self, wet and willing. She was practically his sex toy or something by now the way she couldn't keep her hands off him or her legs together and how she let him have her now pretty much whenever and however he wanted. She remembered standing under the cold falls with Chad's hot cock throbbing in the flat of her hand while she soaped him all over and their tongues twined slowly together, their breath mingling. She leaned back a little so she could look at him. He was truly enjoying the hand job but his blue eyes still looked calm and satisfied somehow. She loved that look. He was looking at her like a guy who was in total control and Kate's heart was hammering against her ribs because he WAS in control, in a way, if you really thought about it. It was up to him. She told him so herself last night when she laid out her plan for getting pregnant at the clinic in Chapel Hill and how it didn't matter anymore if Chad used a condom, or pulled out, or any of that annoying crap because someone else's sperm would get her pregnant if his didn't. So he didn't need to worry. He could do whatever he wanted. If he wanted to he could pick her up right now in his big arms and carry her to the grassy slope and lay her on her back and take her however he wanted, hard and long, or slow and long. And when he was good and ready he could finish however and wherever he pleased. He could pull out and stroke himself and paint her from breasts to curls with his beautiful cum and Kate would laugh delightedly and pull him to her and kiss him and pretty soon they'd be ready to do it again, in a new way that would please him differently. Or he could stare down at her while he drove deep inside her, her legs wrapped tightly around him and her brown eyes pleading for him to hold himself there and finish where they both knew that it would please him most, where nature had designed him to do it. Kate watched him looking at her like that for a long time while she soaped him and rinsed him clean. When she was finished he took the soap from her hand and washed her breasts and stomach and backside carefully and when they'd teased each other long enough they stepped out of the falls, and out of the pool, and dressed in silence. They both knew it would be better if they denied themselves now and saved their strength for later. They walked back to camp and settled down to the tedious work of preparing the equipment and packs for the hike back to the lodge: labeling the urine and hair samples properly, backing up the cameras, indexing the logs. But as the hours passed Kate found her mind drifting, full of strange, thrilling ideas about the chimps and the forest and the mystery of sex. She knew Chad would take care of the mundane details, like always. She found a blank, spiral notebook in the bottom of her pack, and a fresh pen, and she seated herself against a tree on a high bluff with a clear view of the forest, still bathed in mist. Kate didn't stop writing for hours and hours, filling page after page of her notebook with her scrawl. It wasn't until the chanting started that she realized how long she'd been sitting there, lost in her thoughts. The insects and frogs and lizards and birds were calling to each other, almost pleading. The sound of it was so loud and insistent that she thought they were inside her head. She heard the droning of the insects, and the bass notes of the frogs, and the weird, panicky shrieks of the big tropical birds. She thought she could even hear the pant-hoots of the chimps back at M group, miles down the slope. The sun was sinking fast, glowing lurid pink through the dense haze that was pouring off the canopy. All around her the air was full of seeds and spores that the flowers and trees and fungi had released suddenly, all at once, as if at some secret signal. The air was cool and crisp and the stars shone brightly. She stretched her arms above her head and breathed in, gazing out toward the lake. And then she saw the moon: a dark circle. Years later, looking back on her career, Kate would remember this as the day that changed everything. This was the day when she filled her notebook with a draft of her first major article (the one that would make her famous) and with those bold speculations about chimp behavior that would challenge so much of what scientists thought they knew about primate and even human sexuality: about the role played by female pleasure and desire and shattering orgasms in the process of "choosing" a mate, and "selecting" which traits were passed on from generation to generation; about how Mahalia was part of a long line of high status females who had slipped off into the mountains with young, virile, energetic males like Brad who would groom them, and feed them, and fuck them into sheer bliss; how the females passed on the tradition from mother to daughter, transforming the very nature and being of M group in the process, one climax at a time, slowly but surely. Kate had never written so many words in a single day, and she'd never spent half as long doing it, and the feeling afterward was indescribable: that calm sense of exhilaration. She'd worked hard and long and she was ready to reward herself. She felt her eyes drift. It was like something her cells and muscles and nerves did independently of her will, pulled by the moon. As soon as she caught sight of him she felt a rush of adrenaline, the blood throbbing in her veins. He was sleeping on his back on a blanket near the tent in a Carolina blue tank top and long grey shorts with a draw string at the waist and before she knew it Kate had walked to him, and kneeled beside him. His arm was thrown behind his head on the blanket and his armpit was exposed. She lay on her side next to him and pressed her nose to his skin. He still smelled clean and fresh from when they washed each other in the stream that morning but he was sweating in his sleep and his scent filled her nostrils, raw and sharp. She remembered that day at the swimming hole at the beginning of the trip when she and Chad fell asleep on the grass lying close to each other and she woke up with her hand on his taut stomach and her nose in his armpit. She shook her head remembering how crazy it made her feel to come that close to crossing the line, how badly she wanted to explore his stomach, and kiss his neck, and reach her hand into his shorts, and how it made her crotch ache to deny her self. Kate's hands found the bottom of Chad's tank top, pushing it up to expose his abs and chest. She didn't have to pretend with him any more. She'd already crossed the line. She'd already touched him and kissed him and fucked him and sucked his cock and everything else. She closed her eyes and remembered the feeling of his cock naked and spent inside her that first night in the tent, his warm cum soothing her insides. She remembered how electric it felt last night when she finally broke down and let him inside her raw again, after denying herself for days, "limiting" herself to hand jobs and blow jobs, or insisting that Chad stop to put on a condom just as things were getting hot and heavy. She still couldn't believe that she'd let him sweet talk her into fucking him raw again—that ridiculous story about the condom breaking with his girlfriend and how it would be "safer" if they did it without protection because they'd both be careful and they would both know not to get carried away and fuck each other too hard. And she still couldn't believe how very hard she'd let him fuck her, and how hard she'd fucked him back, once she felt the delirious sensation of his fat, naked, pulsing cock buried high and tight inside her because that was what they both wanted and how they both liked it best. And she still couldn't' believe the way she wrapped her legs around him tight like that, and squeezed him with her thighs, and begged him for his seed. The thought of crossing the line again with him tonight was weird and thrilling. Because this time she knew what she was doing. She'd thought about it, and fantasized about it, and weighed the pros and cons of it for days in her mind and now she was ready. She was ready to be fucked—truly fucked!—by this punk college kid from her lecture with the ripped abs and the fat cock and those blue eyes that just melted her inside, loosening and moistening her in all the right places so that Chad could fuck her deeper and longer in all the positions they kept discovering and inventing together, melding their perfect bodies. She was ready to be fucked wide open by him and she wanted it to happen and she was going to do everything in her power to drive him wild with lust tonight so he'd give her exactly what she needed. She was the alpha. It was her choice. But in the end she couldn't really say whether she had a "choice" at all. It all depended what you meant by choice. It wasn't a choice when she ended up in the room next to him at the hotel back in Dar es Salaam for sure. And it wasn't a choice to hear him fuck Elise and god knows who else through the plaster wall, and to feel her mattress shake with the force of his thrusts. She couldn't have expected that! At least the first time. And it wasn't a choice that it made her so wet and excited that she'd ended up fucking herself like a madwoman for the first few days of the trip, and fantasizing about him constantly. Because it was only natural, it was practically inevitable, for a woman at the peak of her sexual power, a woman who had just gone off the pill to make a baby with her husband and whose hormones were in over-drive, it was perfectly natural for her to be aroused by the sight and sound of a hot, young guy like Chad fucking young girls in the next room like that and making them scream with pleasure. And it wasn't her choice to find the pictures of her husband and Elise. And it wasn't even a choice, if you really thought about it, to pair up with Chad when they needed to arrange search parties to find Brad and Mahalia on their safari to make a baby together. No one else was right for the job. So in a way it wasn't a choice either that she'd gone all the way with him that first night in the tent without a single thought for protection and ended up flat on her back, wide eyed and gasping, with her pussy full of his hot sperm, alive and swimming inside her. And that meant that in the grand scheme of things it wasn't a choice what she was doing right now either. Once she'd felt it raw and natural with Chad that first night in the tent the story had to come full circle. She smelled the sweat on his skin, gooseflesh rising at the touch of her breath. Chad was a twenty-year-old guy, and Kate was his professor, and she was about to go as far with him as it was possible for a woman to go with a man. The fact that she was determined to do right by him, and treat him well, and be a good friend to him for as long as he needed didn't make it any less wrong, in the end. He was barely out of boyhood, even though he had the body of a full-grown man, and he didn't stand a chance of resisting her. And the fact that he wanted her, desperately, didn't make it any less wrong either, nor the fact that before too much longer, once she'd woken him up and gotten his juices flowing, their roles would reverse and he'd take "control." She massaged him through his shorts, his cock stirring. Kate's fingers found the drawstring of Chad's shorts and she pulled the end slowly, watching the knot slip free. He stirred slightly. She slid her hand down the ridges of his abdomen and worked her fingers beneath the waistband, then down through his curls. She felt for his crown, exploring it with her fingers, savoring its shape and plumpness. She felt for his shaft. Even soft like this she could sense how long and hard and thick it would be inside her and she felt her stomach twirl, the little blood vessels in her labia and clitoris opening and filling. She felt for his jewels, testing their heaviness. She felt herself moisten, his cock stiffening and jerking a little as she brushed him lightly with her nails. She wanted to see it. His legs were parted slightly and before she knew it Kate was kneeling between them. She leaned forward and pressed her cheek against him, sliding it along his length, purring contentedly. She worked his shorts down slowly, careful not to wake him. There was no shame anymore in admitting it, Kate thought to herself, as his cock sprang into view and she reached for it instinctively. She loved his cock. It was gorgeous. A cock to worship and adore. She loosened her grip and examined him with her fingers, tracing his veins. She brought her pointer finger to that little sensitive cleft in the ridge of his crown, pressing it softly and marveling at the design, remembering how sensational it always felt when Chad found the right angle for both of them, massaging her sweet spot with his mushroom head. She thanked evolution, or god, or the universe, or whatever it was that shaped him that way. His cock was lengthening and flexing now and it looked like one of those bizarre, beautiful fungi that had sprung up from nowhere the night of the storm and that were releasing their spores now through the atmosphere, heavy with fragrance. His cock was like some alien organism that had been crafted and honed for her pleasure over eons and eons and that had reached its state of full perfection on Chad's lean, strong body. She wanted to taste him. She brought her lips to his crown and parted them slightly. She kissed him softly, moistening him with her tongue, slurping him inside her, wet and warm. He tasted clean and fresh but salty too. She felt her breasts swelling. She opened her lips wider and took him deeper inside her throat, gripping him at the base. She closed her lips tightly, feeling him pulse in her mouth. She wasn't sure when he woke up, exactly. He'd probably been awake, and watching her for a few seconds at least by the time she felt his big hands in her hair, massaging her scalp. She'd been so intent on her task that everything else had just faded away. There was nothing else in the wide universe except the sensation of his shaft in her hand—hot and stiff—and the taste of him on her lips, and the warm glow inside her. She was bathing him with her tongue all along his length, and down to his testicles, and all around the ridge of his fleshy knob. And the whole time she was stroking him too, slow and steady, then picking up pace, gripping him tighter. His cock was like a beautiful fungus fashioned through the ages to make her drunk with desire. When she raised her eyes to him he was awake and watching. That cock-sure expression. She smiled at him archly, swirling the underside of his glans with the tip of her wet tongue. It fit perfectly inside his cleft, like it was made for teasing him. "Awwww Kate," Chad groaned, exhaling in a rush. "Did I wake you up?" Kate teased him, slurping him with her lips. Chad nodded sleepily. "Sorry baby," she purred, stroking him firmly and eyeing his shaft, her eyes glazed. "You just looked so delicious sleeping on your back like that. Can I keep going?" Advanced Primatology Ch. 14 Chad nodded again. He gripped the back of her head with his big hands and pushed her toward him gently, careful not to gag her. Kate felt a weird thrill in her crotch and straight up her spine and she relaxed her throat and breathed out through her nose and then her face was buried in his curls and Chad was groaning loud. "Awwww Kate." She loved having him all the way down her throat like that. As far as she could take him. It was like his cock was a glowing wand or something and it was pulsing with energy inside her, like it was pumping some weird, primal energy into her throat, and her esophagus, and it was filling her belly. She wrapped her lips tightly around him and raised her face a few inches, sliding her lips. She paused for a beat and then plunged back down. Once things got started like that they moved quicker than she expected. Before she knew it Chad was standing and she was kneeling in front of him. She pinned his shaft against his stomach and tilted her face up toward him and started bathing his testicles with her tongue and lips, enjoying the feel of his wrinkled skin. She sucked his balls into her mouth, one after the other, stroking him all the while. Her eyes were open and she was looking up at him, watching him closely. Chad smiled down at her. He held himself by the root with one hand while he brought the other one to the back of her head, pushing her slowly. She knew what he wanted and she wanted it too. She relaxed her throat and breathed out through her nose and she let Chad feed himself to her, again and again, his hips thrusting a little. She loved it "rough" like that. Her throat was loosening now and she opened her eyes for him, gagging a little, giving him a show. Chad closed his eyes and groaned and she brought her hands to his ass and pulled him all the way inside her. The next thing she knew Chad was kneeling on the blanket in front of her and kissing her deeply on the mouth while his fingers undid the buttons on her shirt, one by one. She was gripping his cock with both hands and he was completely naked. He slid the shirt from her shoulders and unfastened her bra in one fluid motion and then her breasts were in his hands and he was massaging them slowly. She felt a surge of adrenaline and started jerking him harder, remembering that night in the tent when she kept her clothes on, and teased him about how badly she wanted him to fuck her raw and fill her belly, and he came in a bright arc, high through the air, all over himself, and she collapsed on top of him, laughing into his mouth. He had one hand at her lips now, opening her skillfully. He slid his finger inside her. They were kneeling and facing each other and the insects were chanting and after a while Kate couldn't tell any more, really, where her own body ended and Chad's began. She was gazing dreamily at his cock, and stroking it, and feeling his finger massage her, curling toward her belly. It was like his cock was the stamen of some weird, huge tropical flower and her fingers were some delirious insect or something that had been tempted by the raw scent and the lurid color, and it was like his finger was the long needle-like nose of some other insect, or some fat worm, and it had burrowed into her, searching for the sweet nectar, and now she was closing her folds around him, trapping him in her honeyed tomb. Before she knew it she was standing in front of him—she couldn't say how—and Chad was easing the yoga pants from her hips. He brought his nose close to her and inhaled deeply and without even thinking Kate spread her feet and grabbed a fistful of hair and pressed him into her, groaning loudly. "Ohhhhh Chad. Ohhhh Jesus that's good." It felt wonderful to finally have his warm mouth on her pussy like that, with his lips brushing her folds and his tongue moistening the insides of her thighs, right up the the edge, his beard tickling her. She pulled his hair and guided him into the right position, with his whole mouth covering her and his tongue slithering. When he finally did it she nearly lost her balance and with a few deft motions Chad arranged her on top of him on the blanket. Somehow or other she was right where she wanted to be, without even knowing. She was sitting on his face now and staring down at his gorgeous cock and before without thinking she took it in her hand and bent forward and swallowed him whole while his tongue probed her. It had been ages since she did 69 with a guy like this. Maybe since her honeymoon. Kate relaxed her leg muscles and when Chad's tongue started probing her deeper her own tongue extended, searching for his crown. She closed her eyes and slathered his knob and explored the circumference of his ridge, carefully, all around the delicate edge. She felt his warm, wet fluttering kisses all along her thighs and right up the crease of her leg and then right up to her opening, slick with oil. She lost herself in the sound and taste and texture of everything they were doing to each other and before long she couldn't tell again where the boundary was between them. Her clitoris was long and hard between his lips and she knew it was crazy but she wanted to cum inside him. She wanted to cum in his mouth like she wanted him to cum in her pussy afterward, over and over. She closed her eyes again and tried to focus on all the little muscles along her pelvis and groin so that she could relax and loosen them and it would happen quicker. This wasn't about her pleasure, really. This was about preparing her for what came next. She didn't care if she had an orgasm with Chad tonight because she'd had plenty of those with him over the last few nights, enough to last a lifetime if she needed to, which she didn't, because she knew she would have plenty more orgasms with him in the weeks and months to come. This was about making her lips and labia and tunnel as wet and willing and receptive for him as humanly possible to maximize his pleasure and lead him right over the edge. Just like she was falling over the edge right now, every nerve and muscle vibrating to the rhythm of Chad's tongue. She wanted to let go further and ride the orgasm for as long as she could but suddenly she felt Chad's cock expand in her throat, the vein popping, and she pulled off him in panic. "Don't come!" she gasped. "Awww Kate," Chad groaned. "Don't come!" Kate gasped again, grinding her wetness against his face and making sure to hold her hand steady on the base of his cock. "Why not?" Chad groaned. "Because I want you to fuck me," Kate answered, breathlessly, as her spasms subsided. She sat up and turned around and lay on top of Chad and kissed him. She didn't mind her taste on his lips. "Will you?" she asked, playing with the hairs on his chest. "Will I what?" Chad teased her. "Will you take me in the tent and fuck me now?" Kate asked, pouting, as she waved the insects from Chad's hair. "We'll get eaten alive out here if we stay much longer." Chad sat up toward her, smiling smugly, and with a few practiced motions they were sitting facing each other with Kate in his lap. "You're ready to be fucked now?" Chad teased some more. "Yes," Kate nodded, pouting again and thrusting her pelvis toward him, her sex glistening. "How come?" Chad asked, his eyes flashing. Kate rolled her eyes and blushed. She knew what he wanted. "Because I need your cock!" she purred. "Oh yeah? How come?" "Because I feel so empty without it," Kate whined, enjoying the game, "I need you to fill me up!" "Fill you up?" Chad teased, "What do you mean? I should put on a condom right?" "No!" Kate pleaded, her eyes panicked, digging her nails into his chest. "You don't want me to wear one?" "No!" Kate shook her head hard. "Why not?" "Because I want to feel it naked" Kate whined, pressing her wetness to his shaft and sliding against him subtly. "I like it better raw!" "Oh yeah?" Chad pressed, taking her buttocks in his big hands and squeezing them. "How come?" "Because it feels hotter and it makes me come harder," Kate answered, feeling her pleasure mount as she slid against him a little faster, pressing him a little tighter. Chad laughed out loud. "You need to come on my cock, huh darling?" he purred. Kate nodded desperately, pushing her breasts together with her arms and holding them toward Chad. He bent down to taste them, slurping her nipples one after the other and then pulling off them with a loud pop. "You ready to come on my cock?" Kate nodded again, her eyes pleading. "You're not scared about losing control?" Kate shook her head, smiling. "Why not?" Chad teased. She knew what he wanted to hear. "Because I want it," Kate gasped, sliding her breasts against him and angling her pelvis to bring her opening to his crown. "Want what?" Chad taunted, mercilessly, pinching her in the ribs and admiring the sway and heaviness of her breasts as she squirmed in his lap. "I want you to cum inside me!" Kate told him, turning fiery red all through her cheeks and neck and breasts as Chad leaned forward to taste them again. "I want you to come inside me," she whined again. "Awww Kate," Chad groaned as she found the right angle and his crown slipped quietly inside her. "Ohh Chad," Kate groaned in return, sitting down on him slowly, millimeter by millimeter, coating him with her oils. "Awww Kate," Chad groaned again, louder this time, as Kate sat down on him further and further, and then rose again slowly. Kate could feel the insects biting her all along her back and arms but she didn't care because she was right where she wanted to be. She eased herself down, and pulled her self up, and dropped herself back down again, harder this time. "Feel better now?" Chad asked. Kate nodded her head and looked right in his eyes as she felt herself open for him further. "All better?" Chad teased, matching her thrust. "No!" "Why not?" "Because I want your come!" Kate gasped, starting to ride him faster, her breasts bouncing. "I want you to come inside me!" "How come?" Chad asked, pinching her nipples. "Because it's my fertile day," Kate whined through her nose, grimacing at the sparks of pleasure shooting through her chest, her pussy arching lewdly toward him. "It's my special day and I want your come!" "How come?" Chad asked again, savoring the moment. "Because I want your baby!" Kate moaned, fucking him with more and more abandon as her breasts bounced in his hands. "It's my special day and I want your beautiful baby!" Kate's heart was hammering harder and harder and her thrusts were picking up pace and she felt an indescribable sense of relief and excitement and blind lust as Chad stood up with her legs wrapped tightly around her, and his cock buried deep inside her, and carried her to the tent. Suddenly she was inside it, dark and warm, like a nylon cocoon. Part 2 Years later, savoring the memory, Kate was still shocked by the suddenness of it all, in the end. By how quickly Chad had laid her on her back and filled her with his cock and started thrusting into her with all the pent up excitement and passion he'd been resisting for the last few days. And how he marveled down at her as he watched her breasts heave for him and felt his pleasure build, stroke after delicious stroke. And how automatically she brought her hands to his taut buttocks and felt them tense and loosen and tense again, spreading her legs wider and pulling him deeper and deeper inside her. And then it started. She was flat on her back with Chad looming above her and his shoulders and chest were bulging and his fists were pressed into the floor of the tent and he was throwing his hips at her so hard that he knocked the breath out of her every time so that her breasts bounced hard and full and the sight of it made him fling his hips harder, and harder again, until the whole tent was filled with the sound of their grunting and pleading. "Awww Kate." "Ohh Chad." She pulled her knees toward her arm pits and spread her legs as wide as she could so that Chad's hips would meet no resistance whatsoever from her body as he flung his hips, and flung them again, and his cock drove straight up the length of her, long and hard, like a second spine. She closed her eyes and tried to concentrate on the place where his crown kept kissing her cervix. He was fucking her so hard but somehow his tip felt soft and buttery against her and every time it made contact a little spark of light shot out from the friction between them and hung there for a moment, revolving silently. And every time he plunged again the spark got a little bit larger, until it was the size of a tennis ball and she could feel its warmth and light spreading through her. And plunge after plunge it grew and grew until it was filling her whole body, and the whole tent, and Kate was shaking and crying. And then somehow or other they found themselves in their favorite position. The one they'd discovered together their first night in the tent and that they would return to dozens of times in the years ahead, in all the places they fucked, in Kate's lab, and in her guest house, and in the hotels where she'd come to meet him when Chad's soccer team was nearby. Somehow or other she ended up in his lap facing him, leaning back with her hands on his knees and moving her pelvis in tight circles as he watched her breasts swirl too. That was always the position that made him hardest and longest and she loved the way it felt when their pubic bones touched and his crown bottomed inside her and the sphere of light grew larger and larger, filling not just Kate's body and the tent but the whole forest now, and beyond that, the whole sky. There eyes were wide open and looking right at each other and they were both panting and moaning and making their sexiest expressions so that neither of them would even think about stopping or even changing the pace or the angle or anything because it was all so perfect and they were both so close. The sphere of light kept expanding and pulsing and it seemed to Kate like it filled the whole universe now, all of space, as far as she could conceive or imagine. It was like Chad's cock was a wand of radiant light and it had ignited a spark inside her that had always been there and only now had reached its true proportions. It was like the place where his fat crown met her sweet spot was the center of the universe, the whole universe, and they were making it together, over and over, flash after flash of light. And then her limbs started shaking and she started to fountain all over him, her oils bubbling over. And then his cock got longer and fatter and hotter than she'd ever felt it and she was so excited she thought she'd pass out from the rush of blood to her temples. And then his cock started spurting and pulsing and spurting some more and she thought it would never stop. He was bathing her insides all over like his sperm was some celestial ointment or lotion or something and it was curing their wounds. And now the sphere of light was spinning faster and faster and they were both inside it as Chad filled her and filled her with burst after burst of white, hot seed. "Ohhhhh God," Kate grunted, as Chad's cock continued to pulse inside her and her pelvis pulsed in response. She was brimming over. She could feel how full she was but still it wasn't enough and she kept swirling her hips and coaxing his balls and draining him to the last drop, Chad's eyes shut tightly. "Awwww Kate! Awwww fuck!" he gasped, as Kate reached behind her with her hands and took his jewels in her palms, squeezing them gently, caressing his seed. He was all the way inside her and she was grinding against his pelvis and she could see the little trickles of sperm running down the base of his cock and coating her red lips all over, painting them white. She knew it was enough. She knew it was more than enough. She knew that an average guy shot something like 180 million sperm in a single ejaculation and she knew that Chad had probably filled her with close to twice that many judging by how hard he'd come. And she knew that his sperm were stronger and more vigorous than usual because she could feel them swirling inside her. She pulled off of Chad's cock with a loud plop and in one motion she rolled on her back and held her knees to her chest, her uterus tilted upward. And in a flash Chad was on his side next to her and they were kissing and laughing in each other's mouths. He brought his hand to her opening and coated his fingers with his sperm and then he eased them inside her. He knew somehow that she didn't want to waste a single seed, a single glorious seed, even though he had the testicles of a twenty-year-old guy and they had hours and hours ahead of them, and days and weeks after that, for Kate to empty them, and fill them, and empty them again. Part 3 Years later, at the retirement ceremony in Chapel Hill to honor her pioneering work in the field of primatology, Kate would remember this as the day that changed everything. Looking out over the packed auditorium, the details would flood back to her, with her children and grandchildren seated in the front row, and with her students and disciples arrayed behind them (Karin, Jess, Courtney, Kevin, and—yes—even Elise, and her godson Roger Jr. who was the image of Alex, and dozens of others whose careers she'd nurtured and guided), and with her oldest friend and staunchest rival—Brian—standing in the back, near the exit, looking fresh from the airport as always, and with her best student of all—Chad—in a seat of honor, at the elbow of her eldest daughter, who resembled him closely, a female version of his younger self. Even though Kate was an elderly woman by then, and even though she had a husband, Chad could still make her knees weak. He was gray at the temples but his blue eyes were the same. He was still the same cocky young student who had taken her in the cloud forest. And even though she was at the podium, and in public, she paused to savor the memories, blushing visibly. She remembered all the days of that dreamlike summer together. How they retuned to camp and Kate never went back to M group for the next two weeks because she didn't want to see Mahalia with the other males, and because she wanted to work on her article; and how she arranged it with Alex to rent the luxury suite in the lodge and Chad would come to her secretly every night and they would screw each other senseless on the big plush bed and she would sleep in his arms; and how elated she was when they were back at the hotel in Dar es Salaam, after the trip, enjoying a long weekend at the beach after their hard work in the field, and she missed her period; and how insatiable Chad was for her when they were working in the lab back at campus and they would pause from analyzing the samples for those quick, frantic sessions on the desk or the couch in her office; and how at night, when she was pregnant and her belly was round and full, she would come to him in the guesthouse wearing nothing but her robe and slip out of it and climb into bed with him; and how delicious it always felt to wake up with his leg thrown over her and her pussy full of his sperm. She remembered how much Chad liked to wake her up in the middle of the night, or in the morning, and take her gently from behind. Years later, her eyes meeting Chad's across the auditorium full of her adoring tribe, Kate would remember all of it. And when she began her lecture she would listen to herself in amazement as she told them the same story she always told about her struggles as a woman in the male world of science. It was a story about will and determination and a long series of careful choices that had brought her where she was tonight. And when her eyes met Chad's they both smiled fondly and laughed inwardly because they both knew it was nothing but a respectable lie. It was never up to either of them what happened in the forest. It was never a choice. It was simply what had to happen when a woman at Kate's time and place in life found herself alone and vulnerable and receptive with a young man like Chad, a man fashioned through eons, mutation by beautiful mutation, just like Kate was, to make them fit together just right, limb for limb and organ for organ, delirious servants.
