I'm not swimming naked." "There's no one around Sis. Come on. Don't be a chicken." "You're disgusting." "It's not like I've never seen you naked, Sis." "When have you seen me naked?" "Shelly's hot tub last summer." It was a vivid picture in my mind; the moonlight, the laughter of the girls as they peeled their bikinis off under the water, my sister's white breasts bobbing just below the surface. "Oh really? You mean you can see underwater in the dark?" "Remember when your cellphone rang, and you reached for it and your tits popped out of the water?" "Shut up," she blurted, crossing her arms over her cantaloupe tits. "Sorry Sis," I laughed. "It's not my fault. I'm nineteen, for chrissakes, with no girlfriend, and you're a smokin' hot woman in a Speedo." "Shut UP!" she growled, punching me in the shoulder. "You're also my brother, and brothers aren't supposed to think of their sisters that way." With a disgusted look, she pulled on her snorkeling mask and did a backwards flip into the water. I followed, watching her transform from the gangly gal in the flannel shirt to a mysterious aquatic creature, knifing through the water like a cartoon character from Finding Nemo. It always amazed me the way Sis took to water. She'd been swimming since before she could walk. The water was her stage, her opportunity to shine in a world that usually saw her as awkward and uncoordinated. But there was nothing awkward about Sis in a Speedo. One look at her bouncing rack and her puffy cameltoe and it's obvious you're in the company of a real woman. We were in an unnamed cove at Lake Powell, looking for Indian ruins. Or rather she was looking for Indian ruins, I was looking for her ass cheeks to bust out of the back of her swimsuit. That's probably why I always let her lead on these little excursions - the view was much better. After a short, exploratory dive, she popped back up to the surface. "Over here," she said, with an air of urgency. We did the freestyle out into the middle of the cove, and then she took a series of deep breaths prior to the dive. Sis could hold her breath way longer than I could. I always told her it was because her chest was bigger than mine, but that never went over very well. In fact, I've got a permanent bruise on my arm from being slugged when I cross the line with my tasteless jokes and sexual innuendoes. Sis submerged, and I followed, watching as she weaved her way down into the midst of what appeared to be an old flatbed truck. In the 1960s, when they flooded Glen Canyon and turned it into Lake Powell, all sorts of things were left behind, this truck being one of them. As Sis floated through the driver's door, I headed back up to the surface for another gulp of air. That's the way it usually worked. For every breath she took, I needed two to keep up. I broke the surface, gasped a couple of times, and then headed back down, only to find Sis frantically thrashing, as if the truck had her trapped. "Help!" she gurgled, the sound oddly distant and muffled. She pointed to the strap of her Speedo, which was snagged on what was left of the windshield frame. In her struggle to pull it loose, she had only wedged it tighter, and now her left tit was about to pop out. Frantic to escape, she jerked her other shoulder strap down and reached for the surface, her big, buoyant breasts finally freed from their spandex prison. I grabbed the strap to help strip her suit off, and watched in awe as her athletic body was finally revealed. How many nights had I fallen asleep fantasizing about her naked? And now, finally, my fantasy was coming true, although not quite the way I had planned it. While marveling at her sculpted beauty, her rippling abs and sinewy thighs, the task at hand was to get her swim suit past her flippers. I grabbed one foot, ripped the suit off, and magically, the other foot came untangled. Watching her kick for the surface, it was rather distracting seeing her pussy blinking at me like a fish mouth in an aquarium, but I really didn't have time to enjoy the view. She reached topside in a cloud of bubbles and foam, thrashing frantically. I broke the surface a few seconds later and grabbed her under the arms, trying to hold her above water. With her tits pressed against my chest, she gasped and wheezed, puking a huge mouthful of water onto my shoulder. "Take it easy Sis," I said, trying desperately to keep us both afloat. I was never very good at treading water, and treading water for two was even harder. Clenching me in her death grip, she just kept coughing and wheezing while I enjoyed the feel of her stiff nipples against my chest. A couple of minutes went by, long enough for me to get to know every curve and crevice of her luscious body as I held her aloft. In her effort to stay afloat, she had straddled my thigh, and the fact that her bare pussy was rubbing my leg was not lost in the commotion. "Jesus!" she gasped, "that was close." "You okay now?" I asked, pretending I wasn't totally enjoying the feeling of her naked body pressed against mine. "I guess so," she sighed, loosening her grip on me, "except that I'm bare-assed naked." "See? If we'd gone skinny-dipping like I suggested, none of this would have happened." "Shut up," she said halfheartedly, too whipped to slug my shoulder. We swam for the boat, side by side, me watching her tits slosh through the water, she acting like she didn't know I was getting an eyeful. "You want me to boost you in?" I asked, as we paddled up to the edge of the skiff. "I guess," she sighed. In all the years we'd been out in boats, she had never once needed help climbing back in, but she did today. I grabbed the edge of the boat, my arms spread apart, and braced myself while she used me as a ladder to climb aboard. Then I followed, boosting myself up and finding her curled up on the seat like she was trying to take a crap. "Over there Sis," I said, pointing to the other seat, "unless you want to drive." "Whatever," she grumbled, moving to the other seat while keeping her arms crossed over her chest. I pretended not to look, but of course, I did look. The funny part was, not two hours ago I was trying to peek through the flap of her tent while she was climbing into her Speedo, and now it was all there for me to see. It gave me a strange sense of power over my big sister. She was always the one in charge, but not now. "You want me to go back and try to retrieve your Speedo?" I asked. "You can if you want to, but the way it started ripping up the side, it wouldn't do me much good, would it?" "I think it would look great on you Sis, depending on which side I was looking at, of course." "Bobby!" "Sorry Sis. I couldn't resist." We sat there for a moment, me pretending not to leer, she, doing everything in her power to prevent it. Then she looked up, accidentally showing me a pig, pink nipple. "You didn't happen to see a towel down there, did you?" I had to laugh to myself. She was the one who said we wouldn't need towels, or extra shirts, since we'd only be gone an hour or so. Now, she would have killed for a towel, or a shirt, or anything to cover up with. "Keep your eye on the shore, Sis. Maybe there'll be an old garbage bag or something." She shaded her eyes to scan the beach, revealing not just a big pink nipple, but a whole breast, and then her face lit up. "Over there. See it?" I guided the boat across the cove, where the remnants of an abandoned camp were scattered about. While she waited, I waded ashore and foraged what I could; a plastic grocery bag, an oven mitt, and a kitchen towel about the size of a magazine. "Did I do good, Sis?" "Asshole," she grunted, staring at the booty as if it was garbage. Well, technically, it was garbage. "I hope you're enjoying this," she said, as she reached over the side of the boat to rinse the towel. Again, I tried not to look, but this was a whole new view I hadn't seen yet; her round tits elongating as they dangled over the edge of the boat. Satisfied with the cleanliness of the towel, she draped it carefully between her legs, and then proceeded to tear the grocery bag open, so that she could cover her tits with it if she had to. "Um... Sis, do you want to turn around?" "Why," she asked, giving me her annoyed look, "so you can pee into the lake?" "No, I'm going to rub some SPF 45 on your back." "You're so thoughtful," she said sarcastically, as she got up and repositioned herself, giving me yet another fleeting glimpse of the backside of her camel-toe. I was past the point of marveling at its sculpted beauty, preferring to imagine what it smelled like and how it tasted. Putting SPF 45 on Sis's back was no big deal. We oiled up each others backs all the time. But this time, when I got to her bare ass, a dilemma ensued; to touch, or not to touch? I chose the former, and much to my surprise, my wandering hands where not fended away by yet another clenched fist. Sis looked over her shoulder at me, giving me a nice peek at her left tit. "I'll bet you've been dying to do that for ages." "Only since you turned eighteen, Sis," I said, as my fingers plied her springy butt, coming perilously close to her ass crack. "Pervert," she grunted, returning to her stoic pose with her arms crossed over her chest. As I was running out of places to apply SPF, my hands wandered onto her hips, where I imagined I'd be holding her while I ate her pussy, or pounded her cunt with my hard-on. "Want me to do the front too?" I asked innocently. "Want me to knock your teeth out?" she answered. "No, but I would like if if you'd do my back." "I'm not turning around till you do." "No problem Sis," I said, bidding goodbye to her naked body and spinning around on my seat. With her hands slithering across my back, I couldn't help but sigh. Just knowing she was naked, touching me, was enough to give me an instant hard-on. As she completed her task, I succumbed to my forbidden desires. "You can do my front too if you want to Sis." "In your dreams, asshole." "You owe me, Sis." "I don't owe you shit." "Didn't I just save your life a few minutes ago?" "Yes. And haven't you been staring at my tits and ass and pussy ever since? Isn't that payment enough?" "Letting me do your front, and you doing my front would be payment enough." She thought for a moment. "I'm never going to hear the end of this, am I?" "Nope." Silence. For about a minute. Finally, she let out a long sigh. "All right, pervert, you win. But don't get fresh with me, or I will knock your teeth out." I gave her a moment, and then I turned around. She was sitting there, her knees locked together, her back ramrod straight, her tits proudly displayed like a Playboy model. Flashing me a contemptuous look, she handed my the SPF tube. With trembling hands, I squeezed out a dab and spread it on the front of her shoulder, letting my fingers trail down to the top of her breast. "Why did I know you'd want to start there?" she asked, narrowing her eyes. "Because it's the best part?" I answered, swooping my hand down under her breast, just missing her stiff nipple. It was quite awesome, finally feeling those big round tits I'd been lusting after all these years (since she turned eighteen, of course.) They were softer than I had imagined, and I wondered how they managed to be so buoyant and yet so full and heavy. It was a mystery that would require much study and research. "Just get it over with?" she whined. "The longer this takes, the more sunburned I'll be." I let my fingers graze her nipple, but my sister didn't flinch. Determined to convince her how enjoyable it could be, I greased up the other tit, swirling closer and closer to her nipple but not touching it. "Bobby?" she sighed, "you haven't got a clue. No matter what you try, you're not going to force me to enjoy this. This is strictly for your pleasure, not mine." "I'm cool with that," I said, venturing down her tummy, clear to the top edge of her trimmed bush. "One more thing, Mr. Pervert? Unless I stand on my head, I'm not going to be needing SPF on my junk, so just consider that part off limits, okay?" "Sure Sis," I answered, prying her legs open to get at her inner thighs. "Sicko," she grunted, grabbing the side of the boat so she could lean back and spread her legs. "Have you considered gynecology as a career choice? That seems to be your main interest these days." Gazing at her most private place, it was as if her slit had been designed my Michael Angelo; the lips glossy-smooth like marble, the hood over her clit hinting at the same kind of mystery that lay behind the Mona Lisa's smile. I was in awe, but at least I remembered not to hang my mouth open while I stared. "You're really pretty down there Sis," I stammered, my eyes glued to the pink prize. "Compared to what? The women in Hustler?" "Compared to Ruth, for one." "You did Ruth? The one with the buck teeth and the pimples and no tits?" "And Amie," "Whoa, now there's a hot number. Is she still in Weight Watchers, or did they kick her out for breaking their scale?" "I'm just sayin' you look nice down there." "Thanks Bro, that's good to know. I'll keep it in mind if I ever decide to become a nude dancer." By this time, there was nothing left on Sis to SPF, so I handed her the tube. She snatched it from me and squeezed out a huge blob into her palm. Then she shoved me down into the bottom of the boat, straddled me, and with a couple of quick swirls, smeared lotion all over my chest, as if it was some kind of race. "Come on Sis," I whined, staring up at her dangling breasts and her puffy labia, "be nice." "I am being nice," she said, squeezing another glob out of the tube, "I'm not knocking your teeth out." Her hands darted to my legs, starting at my ankles and slipping and sliding all the way up to the edge of my cut-offs, which did wonders for my aching dick. "Um, Sis?" "Um, what?" "I was thinking, you know, since you were naked when I did your front, shouldn't I be naked when you do mine?" "Really? Is that what you were thinking?" Her hands were frozen at the tops of my thighs, almost touching my balls. "And if I finish doing your front with you naked, I won't owe you anymore?" "I promise, Sis. I promise." "You're disgusting, you know it Bobby?" "I know Sis. I'm sorry." I watched, holding my breath, while she unbuttoned my cut-offs. Then, with a brisk flick or her wrists, my cut-offs were down to my knees and my hard-on was bobbing in the sunlight. "That's it?" Sis giggled. "What happened? Did the cold water make it shrink?" "Don't ruin the moment Sis, please?" She nonchalantly grabbed my shaft, and then with the other hand she spread a gob of lotion on the purple head. I closed my eyes. Then I opened them, remembering that Sis was naked, and I really shouldn't pass up the opportunity to enjoy her nakedness. "Is that how you like it pervert?" she cooed, with one hand sliding down and cupping my balls. "Yeah," I gasped, already getting close. The feel of her hands on my cock, the sight of her tits bobbing with the rocking of the boat, the unencumbered view of her puffy pink peach of a pussy, it was a dream come true. Well, a dream come true would have been me sliding my dick all the way into that puffy pink peach of a pussy, but a guy's got to settle for what he can get. "Faster?" she sneered, her pace quickening, her fingers gripping me tighter. "Yeah," I warbled, as the semen eased up my shaft. I hung my mouth open and gazed into her eyes, imagining this to be foreplay before we made love for real. I knew she was on the pill, and I knew how easy it would have been to just shove it in and cum inside her. With that in mind, the first spurt erupted from my stinging dick and shot clear over my shoulders and out into the lake. She kept pumping, and I kept squirting, or rather dribbling as my balls emptied all over my stomach. That's when I felt it, the utter surrender of giving yourself to your partner in sex. The vulnerability, the openness of it, it made me realize how much I loved my sister. I wanted to hug her, hold her, whisper in her ear, all the corny stuff that lovers do. As she gazed down at me I felt the same sense of utter devotion coming from her. Or maybe I only imagined it. Whatever. I'll give her this much, it was the best damn hand-job I'd ever had, and she didn't stop milking me till I was limp as a wet noodle. "Happy now," she said, wiping her slimy hand on my cut-offs. "Yeah" I sighed, staring up at my bad-ass nasty sister, all naked and shiny from the suntan oil. "I don't owe you anymore?" "No Sis, we're cool." "Actually," Sis said, leaning back and giving me an amused stare, "we're not cool. I got you off. Now you owe me one." "One what?" I stammered, anxious to fulfill her every need, "one orgasm?" "You don't know how to give a woman an orgasm." I hung my head. There was a kernel of truth to her words, but I certainly didn't want to admit it. "Try me" I said, perfectly aware of Sis's competitive nature. "You owe me," she snapped. "Let's just leave it at that, okay?" With that pronouncement, she replaced the kitchen towel between her legs and gazed off into the distance. Confused, happy, sad, and out of breath from my orgasm, I pointed the skiff towards camp, gazing fondly at my stubborn, sexy, naked sister. ***** "Oh great," Sis moaned, as we rounded the corner into our cove and spotted the gaggle of campers set up next to our site. "Where did all these yahoos come from?" "I don't see any little kids, Sis. I don't think the adults would mind if you came strutting up the beach in your birthday suit." Seeing the punch to the shoulder coming, I dodged, and she missed, but her tits did do a delightful little dance as she regained her balance. "Wrong!" she pronounced, folding her arms across her chest again. "I'm going for a swim, right over there on the other side of the rocks, and you're going into camp and fetching my bikini out of my bag. And a towel. A big towel." "No problem Sis. I'd do that for you." I watched as she slipped into the water, imagining the submerged view of her pussy as it opened and closed like a fish mouth, and then I cruised the boat into shore, cutting the engine and gliding in silently. That's one of the things I like about boats - the way they can float practically forever if you give them a firm enough push. I trudged up to our campsite, ignoring the new neighbors, and checked Sis's tent. We were still using the same camping gear from when we were little, two matching one-man tents for Sis and I, and a big one for Mom, except Mom no longer had a husband to keep her company. Since Sis's tent was so tiny, she used Mom's tent as a dressing room, and when I didn't see her bag in the little tent, I proceeded to Mom's tent and pulled the flap open. Staring into the dark, musky tent, I couldn't believe my eyes. Was that my mom, lying there bare-ass naked, snoring softly, with a vibrator laying across her tummy and a catsup bottle stuck halfway up her cunt? I blinked, but the image didn't change. Right away I noticed the resemblance to my sister - the same wide hips and full breasts, although Mom's breasts had pretty much deflated over the years. Mom and Sis both had the same puffy pussy, except Mom's was shaved bald, with more of a swirl up at the top of her slit. Between that and the funky/sweet/sour smell of sex, I was overcome with an emotion that was totally unfamiliar to me. It wasn't disgust. It wasn't desire. Curiosity perhaps? Some kind of animal instinct? Lake of Forbidden Desire I decided it was the bald pussy that was making me feel so intrigued. I'd never seen one before, and the last place I ever expected to encounter one was between my Mom's legs. Not that I ever had those kinds of thoughts about my Mom, but at this moment, I was having those kinds of thoughts. Big time. I could already feel my dick swelling. Carefully, without making a sound, I dug into Sis's bag and found her red bikini and her big purple beach towel. Then I backed out of the tent and let the flap slither closed, taking on last longing look at my naked mom. As I tiptoed back down towards the boat, I started thinking; what if Mom had been getting herself off when I pulled the tent flap open? Would she have stopped? Would she have asked me to help out? I managed to launch the boat with a big enough push to float a good ways out into the lake before starting the motor. The last thing I wanted was my Mom realizing I'd seen her in such a state. She was, after all, a tenured professor at the university, not some trailer park sex addict. Sis was doing a lazy side-stroke when I reached her, her tit cutting through the water like the hull of a sailboat. It was a beautiful sight, and the ache in my cock continued. "You want a hand up Sis?" "Why? So you can leer at me while I'm putting on my bikini?" "Well... yeah." "Just hand it to me." I complied, and pretended not to watch while she put it on, draping the top around her neck while she pulled on the bottom. When she was satisfied that neither one of her tits was hanging out, she did accept a hand up into the boat, and then we cruised back into our cove, the tension between us palpable. But Sis was like that - moody. The older I got, the more I realized that it's a woman's prerogative to be moody. It just comes with the territory. As we neared our beach, Sis wrapped the towel around her, and began muttering about the annoyance of having neighbors ruining our camping trip. But her muttering ceased when she noticed the long lanky dude in the cutoffs fiddling with his boat. He looked to be mid-twenties, probably a college kid, probably here with his folks, since the people sitting at his picnic table were considerably older. "I don't really need this," Sis said, shucking off her towel. Then she pushed her boyish blonde hair back and hitched up her bikini top, which had a tendency to make the bottoms of her breasts show. The bikini was left over from her high school days, and she'd gained a couple of pounds since then - all in the right places. When the boat reached the shore, I hopped out and hauled it in with the rope while Sis sat there like royalty in a carriage. With the boat secure, she arose and stepped glamorously onto the sand, striking a pose that would have been more appropriate on the front page of a hot rod magazine. "Hey," the lanky dude said with a smile, and I knew Sis was a goner. She loved guys with broad shoulders and six pack abs, and this dude was right up her alley. "Hi," she said with her flirtiest smile. "I guess we're neighbors. My name's Alice, and that's my little brother Bobby." I absolutely hated it when Sis introduced me as her little brother, but what could I do? "Hi Bobby," the lanky guy said, extending his hand, "My name's Hank." I shook Hank's hand, not because I wanted to, but because I didn't want Sis getting pissed at me. While the two of them started in with their flirty small talk, I headed up to camp, pissed off, jealous, and totally confused. "We're home, Mom," I said, in a voice loud enough to be heard clear across the lake. I certainly didn't want Sis waltzing in there and finding Mom still asleep with a catsup bottle stuck up her cunt, and then putting two and two together and realizing I'd seen the same thing. I heard stirring in her tent, and I let out a sigh of relief. One more crises avoided. Mom emerged a few minutes later, looking sleepy and satisfied. The sight of her loose tits jiggling under her T-shirt set my dick to twitching and writhing in a most distracting manner. At that moment, I sort of wished none of this had ever happened. Sex can be so much fun, but it can also be so freakin' complicated. It made me realize why some guys just hire a whore every now and then. Sex with no strings. What a concept! I helped Mom fire up the Coleman stove, and then she proceeded to make us hot dogs while I changed into my jeans. "Go tell your sister lunch is ready, will you Hon?" Did my mom have any idea the new connotation "Hon" had after seeing her in her most intimate moment? "Sure Mom," I said, trying to rid the image of her hairless pussy from my mind. I plodded down to the shore and told Sis it was time to eat. "See you later, Hank," she said in that flirty way she uses when she's trying to score a new guy. He waved, and then Sis and I were walking back up the hill to our camp. "Um, Sis?" "Um, what?" "About today, in the boat..." "Don't worry," she said, touching my arm gently, "it's our little secret, okay?" "What I was going to say was, I'm sorry if I crossed the line." "No sweat. Like you said, you're a guy, I'm a girl in a swimsuit, or without a swimsuit. We're adults. If I didn't want it to happen, it wouldn't have happened." "So, you're cool with it?" "I'm cool with it as long as you never, EVER pull that shit on me again." "Understood Sis." By this time, we were coming up on our camp, so I turned the conversation to more pressing matters. "Do we tell Mom you almost drowned, Sis?" "If you tell her that, I can guarantee you that not only will I never give you a hand job again, I'll cut your dick off while you're sleeping." "Got it, Sis." She gave me a gentle tap on my sore shoulder, and then we were at the picnic table. "Alice?" Mom said, shoving her glasses down to the end of her nose, "weren't you wearing your Speedo when you left?" "It ripped Mom, out in the lake, so I waited while Bobby came back and got my bikini, and then I changed under water." "Really?" Mom said, giving me a curious look. "Bobby came back and got your bikini out of my tent?" Suddenly, I felt about two feet tall. "Well," Sis whined, "what was I supposed to do? Walk back up here naked?" My mom shook her head. "I guess I didn't realize those Speedos ripped that easily. Were you two roughhousing? You know you're getting too old for that." "Mom," Sis said, rolling her eyes, "that Speedo was like 5 years old. Even the new Speedos they're using in the Olympics are ripping after only thirty hours of use." While Sis rattled on, Mom reached in the ice chest and grabbed a wine cooler, something she usually saved for after dinner. I felt bad for her, but what could I do? "Mom?" Sis whined, "where's the catsup?" "I don't know," she answered, raising her eyebrows. "Have you seen the catsup, Bobby?" I wished I could have just disappeared, instead of confronting this perverted can of worms. "No Mom, I haven't." "Hmmm..." she said to herself, "where could that catsup bottle be?" ***** After lunch, Sis headed back over to hang out with Hank, and I went down to the shore, for a walk, or to get some air, or something. Mainly, I just wanted to get away from camp and figure things out. Was I having sexual feelings for my mom? And also my sister? Was I turning into a pervert? Would I go to hell for what I'd done, and what I was thinking about doing? Suddenly, I too, needed a wine cooler. I was just thinking about turning back when I heard Mom's voice. "Hey? Wait up." She came trotting after me, her hair blowing behind her, and for a moment I could see her at nineteen; trim, sexy, full of hope and promise. Instantly, I got a huge lump in my throat. "Hi Mom," I said, stuffing my hands in my pockets. "Hi Bobby," she said, catching her breath from the short jog. "Listen, can we talk for a minute?" "Sure Mom." I had a pretty good idea what she wanted to talk about, but I thought I'd let her take the lead. What startled me was the way she hooked her arm in mine and cuddled up to my side. It was creepy. And sensual. "About what you saw today, in my tent..." "I'm sorry Mom. I should have knocked." She laughed, and again I saw the nineteen year-old Mom, not the forty-year-old Mom with no husband and a vibrator for a lover. "No," she continued, "we needed to have the sex conversation but we never got around to it. It's one of those things that parents avoid, especially single mom parents with a nineteen year-old son." I waited for her to continue, feeling somehow excited and yet calmed by her closeness. "We all need sex," she said, in her professorial tone. "It's just part of nature. You're in your sexual prime right now. So am I. I probably don't masturbate as often as you do, but I need the release, and I need the escape. We can pretend sex isn't a part of our being, or we can accept it and make it work to our advantage." "How do we make sex work to our advantage?" "In a relationship, it's the glue that keeps people together when everything else falls apart. That's what happened with your dad and I. We both got so caught up in our careers, we neglected the sex part, and now here I am, screwing a catsup bottle with my vibrator set on ten." We continued on down the beach in silence. I wasn't sure what this had to do with me, but I liked walking along the beach with Mom on my arm. It made me feel more like a man, and less like a boy. By this time we had climbed a little bluff, and below us was a secluded cove hidden from the rest of the campsites. Mom stopped and let out a big sigh. "Your father and I used to come up here and swim naked. In fact, this is where your sister was conceived. I haven't been swimming naked in ages. Have you?" "Um... are you sure you want to know that, Mom?" "Good point," she laughed, unhooking her arm from mine. Then she gave me a shove, and sprinted for the beach. "Race you to the water!" I could have taken her easily, but I let her stay a step ahead of me. It was fun, seeing the nineteen year-old surface from my Mom's forty year-old body. We got to the water's edge, and she flopped down in the sand and kicked off her shoes. "Come on!" she blurted, just like a kid, "let's do it before someone comes." She stood up, pulled her T-shirt off over her head, and her once-proud breasts dangled free, her big, puffy nipples aimed slightly downward, but still scrumptious looking. I can only imagine the look on my face when she whipped her shorts down, revealing her hairless mound once more. It was amazing. In less than ten seconds, she was totally naked, her Mona Lisa body rivaling that of my sister. "Well?" she smirked, planting her hands on her hips, "you coming, or are you just going to sit there and stare?" "I'm coming Mom," I said, suddenly aware of my growing hard-on. She turned and sprinted for the water, giving me a chance to strip without an audience. It was kind of sad, watching her floppy tits slapping against her chest as she bounded into the water, especially considering how great they must have been when she was my age, but that didn't dampen my desire for her. By the time I was naked, my dick was stiff as steel, pointing directly at my mom's fleeting figure slicing through the water. She didn't look back until I was waist deep, and I was grateful. I didn't want her to think I was a pervert. For all I knew, the swimming thing could have been a totally innocent adventure with her. Women are such a mystery, and my mom was no exception. "Isn't this great?" she beamed, her deflated breasts floating close to the surface. The water was armpit-deep, with a gentle current pushing us back and forth, almost imperceptibly. "Turn around," she said, almost in a whisper. I complied, and the next thing I knew, I felt her fingers on my back, delicately fluttering up and down my spine. 'Cool, huh?" she said, into my ear. "Touch feels totally different under water." Her fingers slid lower down my back, clear to my ass cheeks, and below. I let out an involuntary grown as my dick throbbed with desire. Her fingers continued around onto my stomach, and up the middle of my chest. With her arms wrapped around me, she eased closer, and suddenly I felt her nipples grazing my back, undulating as the current ebbed and flowed. "You like?" she asked softly. I nodded, speechless, as her hands slid down my sides and onto my hips. She was careful not to touch my dick or balls, but she didn't have to. Every nerve in my body lead to the head of my cock, and in no time I was on the verge of squirting. "Okay Hon," she whispered, "now that I've shown you how to do it, it's your turn." Letting her arm trail loosely around my waist, she slid next to me, and then eased in front, my stiff dick grazing her ass cheek. I let my hands settle onto her back and I did what she did, exploring her body delicately but discreetly as she moaned softly. "I love that," she whispered as my hands slithered down her back and onto her dimpled butt. I left them there for a while, letting my fingers probe deeper and deeper under her ass without actually touching anything important. She kept inching closer, till there was no room between us. I took that as a sign to move my hands to the front, which I did with slow, gently strokes around her hips and onto her tummy. "My tummy used to be as firm as yours," she said, leaning her head back and giving me a husky laugh. "Then I carried you and your sister to term, and my tummy was never the same again." She slid my hand lower, till it was brushing the top of her hairless mound. "My tummy used to be firm like that." I wasn't sure if I was supposed to go lower or higher, so I just hung around there for a while. Silently, she took my hands and slid them up under her tits. "Lift," she whispered, more as a command than a suggestion. I cupped her breasts gently and pulled them aloft. "That's where my tits were when I was your age. Can you imagine how great they looked?" She did a little shimmy, throwing her hands up in the air like she was dancing. "I was rockin' these tits in those days. If you ever get to feel our sister's tits, you'll find out what mine were like." "I like feeling yours mom." "You bullshitter. You just want to get your rocks off. I can feel you twitching down there." By this time, my stiff cock had settled between her legs, periodically nudging her thighs, or ass, or who knows what, but I think it was all part of the plan. Gaining confidence, I let my fingers slide up onto her rubbery nipples. One little pinch and her whole body jerked, jamming her ass up against my groin. "Feel down here," she whispered, guiding my hand down her tummy. Suddenly, my fingers were tracing the path of her slit, gently, barely touching. "This is what it's all about, Bobby. It's the essence of life. It's your destiny, and your downfall. Someday you'll find the right one. but they're all pretty much the same." Touching her down there, it just seemed so perfect, so natural. As I stroked her gently, she leaned her head back against my chest, her ear brushing my cheek. At that moment, I really wanted to kiss her, but I held back, waiting for her to dictate the next move. "Put your finger right here," she whispered, showing me how she wanted it. As I rubbed, she undulated, thrusting her pelvis almost imperceptibly. As the thrusts became more mechanical, more obvious, her breathing got heavier. At this point I realized that if it wasn't for the hand job earlier, I would have been polluting Lake Powell with my cum right about now. As it was, I was on the verge, but also able to hold back, seemingly indefinitely. "Harder Bobby," she gasped, grabbing my hand and clamping it up against her bald pussy. "Just like this" she commanded, easing my finger back and forth. Satisfied with my technique, her hand flitted onto the head of my dick and fingered it lightly, more like a tickle than a touch. She leaned back and craned her neck to look at me. "Are you okay with this, Bobby"? "Yeah," I gasped, thrusting my hips to match her rhythm. We stayed like that for a few minutes, building up the tension until I thought I was going to lose it. "Do you want to cum inside me?" "Yeah," I whimpered, dying for release. With a gently but authoritative grasp, she guided my dick into her cunt, and it slid in effortlessly, as if God had designed her vagina to fit my dick perfectly. "Oh God Bobby, that feels so good. Much better than a catsup bottle." We both laughed, but then her laugh turned into a raggedy sob. "Oh God!" she gasped, "here it comes." She tensed up, and then she was twitching and shuddering uncontrollably, her pussy chewing on my cock like a toothless monster. I managed to pull almost all the way out, and then jam it in hard enough to send my semen spurting deep inside her. Even after Sis's hand-job, I still had plenty to give my mom. "Oh God!" she sobbed, flinging her head back against my neck. I kept pounding into her with a seemingly endless load of cum, wishing I could kiss her lips and feel her tits against my chest. Feeling so utterly connected, so enveloped by her sex, it was as if the sole purpose of our lives was this very moment, this primal act of procreation. We stayed like that for a while, her hand cupping my balls and holding my dick inside her, my finger gently caressing her swollen clit. I let my free hand wander over her soft body, tracing around her puffy tummy and up between her tits while she gasped and sighed and tried to catch her breath. The feeling of oneness, the perfection of our union, it was like a revelation, a confirmation of our destiny. Finally, she let me dick ease out of her, and then we were side by side, my arm around her waist, her fingers cradling my shrunken cock. "That was some swim, eh?" she said quietly, looking at me out of the corner of her eye. "Yeah. It was cool." "You'll have to try it sometime with one of your girlfriends." "What about trying it with you again, in about twenty minutes?" "Shut UP!" she giggled, giving me the same love tap I got from Sis on a daily basis. "Is that all you guys think about?" "You said it yourself Mom. We're both in our sexual prime right now. What else is there to think about?" "You've got a point, Bobby." By this time, we were edging our way towards shore, with the water well below her breasts. I tried not to stare, but how can an eighteen year-old guy not stare at a pair of naked tits when they're within arm's reach? "Bobby?" she asked, taking my hand like high schoolers do when they're first dating, "we probably don't want to let your sister know, right?" "No shit. She's whacky enough already, without something like this to complicate her life." "Bobby! Your sister's not whacky. She's just going through a difficult time right now. She's had horrible luck with men, and she's not doing well in school. Thank your lucky stars that she's not on drugs, or worse." "You're right, Mom. Sis isn't whacky, just stressed." "Speaking of stressed, how did that ripped Speedo come about?" I thought about telling the truth, but figured this wasn't the time. "She dove in, from the boat, and the back split wide open." "Open enough for you to see anything?" "Well..." I thought, wondering what the right answer would be, "sure I saw something. I saw her naked, but she was in the water..." "Oh my. I hope it doesn't cause problems between you two." "No problem Mom. Sis is a big exhibitionist. Didn't you see her in her red bikini with her tits almost popping out?" "I did notice, but what's a mom do do?" Back on the beach, we pulled our clothes on, both of us being careful not to watch the other. It was a tender moment, as if we both knew it was too early to admit we were lovers, but it was too late to pretend we weren't. As we headed back to camp, I took Mom's hand in mine. It was reassuring, in an innocent sort of way, maintaining that human contact we all crave. Lake of Forbidden Desire "So what's for dinner Mom?" "I was just going to ask you the same thing. Now that you're a man, and not a boy, why don't you decide?" "You brought steaks, right?" "If you want to grill em' then I brought em." ***** The next day was to be our last at the lake before breaking camp and driving back to Phoenix. Sis was going on a hike with Hank, and Mom was committed to meeting some fellow professors over at the Rainbow Bridge, so I had the day to myself. I perched myself in my lawn chair and dove into Duma Key by Stephen King. I like page-turners, and a Stephen King book can do that to you. I was about a hundred pages in when I heard a familiar voice down by the beach. "Fucking asshole scumbag motherfucker piece of shit!" It was Sis, stomping up the trail to our camp. "What's up, Sis?" "Just shut the fuck up and leave me alone!" she snapped, in that bitchy tone of voice I had learned to respect over the years. I watched as she flung her day-pack on the table and stomped into Mom's tent. She emerged moments later, wrapped up in her terry-cloth robe, and proceeded down to the restrooms. I knew a hot shower would calm her down, so I went back to my book, distracted by the vision Sis naked, her body all soaped up... Twenty pages later she was back, nibbling at the Fritos on the picnic table. "Why do men always have to be such assholes?" she asked, inspecting her corn chip as if it had bugs on it. "Because we think with our little heads, instead of our big heads?" "Good answer," she said, finally making eye contact. I could tell by the jiggle under her robe that she was naked, or at least bra-less, which made our conversation that much more interesting. "Want to talk about it?" I asked. "What's to talk about? All he wanted was a blow-job and an ass fuck. I'm not into that, at least not on a first date." "Doesn't an ass fuck hurt?" "That's not the point. I have needs too. I'm not a fucking blowup doll. I'm not a cum receptacle." "You're right Sis. You need to start looking into a guys heart, not at his chest and his abs." "No lectures please. I'm not in the mood." Staring at my stressed Sis, imagining her naked body all soapy and clean, I figured what the hell, might as well go for it. "I know what you need, and it's not what you think." "What do I need, oh wise one?" She cocked her head and gave me that annoyed look, the one I've seen her use a thousand times. It's the 'you're never going to win this argument, but go ahead and try' look. "You need a nonsexual full body massage." "Gee," she sneered, "I wonder where I'm going to find a nonsexual full body massage around here?" "I could give you a nonsexual full body massage." "You couldn't give a nonsexual full body massage if your life depended on it." "Wanna bet?" "Don't make me laugh. That's one bet you'd be perfectly happy to lose." "Whatever," I said, picking up my book. I watched out of the corner of my eye as she nibbled her chips. wondering if she'd fall for it. "What would you use for massage oil?" she asked, feigning disinterest. "Mom's got some olive oil in the food box." "That's gross! You're going to use cooking oil?" "That's what they all use." "And you know this how?" "Ruth had a massage video, and that's what they were using." Sis continued with her chips, but I knew it was just a matter of time. Finally, she looked my way. "So how do you wash off the olive oil when you're done?" "Well," I said, trying to sound calmer than I actually was, "you use a dry towel sprinkled with after-shave, and then you let the rest soak in. It's good for your skin Sis. If we were home you could google it and find out for yourself." She scooped up a couple of more chips and sauntered over to Mom's tent, adding a little extra swing to her hips, or at least that's how it appeared to me. I went back to Stephen King, but I just kept reading the same page over and over because it was impossible concentrate. All I could see was Sis, naked, her bouncy tits covered in massage oil... "Oh Bobby," she called from the tent, "I'm ready." Springing to my feet, I grabbed the olive oil and strolled briskly to the tent. I would have sprinted, but I didn't want it to be too obvious about how anxious I was to get started. As I pulled the flap open, I found Sis lying on her tummy on top of her purple beach towel, naked except for a little scarf she had placed over the crack of her ass. "Scoot up Sis, so your chin is hanging over the end of the mattress, the way they do it with a real massage table." "Is that the way the do it? I wouldn't know. I've never paid a girl to jerk me off and call it a massage." "Neither have I." "Liar," she said, peeking back at me, which revealed another couple of inches of her left tit. She did as I instructed, nestling her face between two of Mom's pillows, and I proceeded with the massage. I started out on her shoulders, alternating between the light feathery touch my Mom showed me and the firm strokes a real masseuse would use. I was on my knees next to her, which meant her squashed left tit was constantly staring at me, or rather I was staring at it, and in no time, my dick was hard as a rock. It was distracting, but I was determined to prove to Sis that I was, indeed, capable of putting her needs before mine, even it it meant squirting in my pants. As my hands ventured closer to her butt, her sighs grew deeper, and in no time her little scarf had slipped off, leaving her totally naked. "That's nice," she whispered as my fingers plied her firm cheeks, kneading them back and forth with enough force to spread her ass crack open and reveal her pink anus. With one hand working her ass, I let the other slither down her thigh and back up again, each time coming a little closer to her labia, which were now in full view. I kept at it for what seemed like ten or fifteen minutes, one hand on her ass, the other teasing and then retreating. With each stroke I could perceive a slight but constant rise and fall in her hips, and I knew I was on the right track. Finally, she couldn't take it any more. "Is this where I'm supposed to roll over on my back?" she asked, barely audibly. "If you want to," I said, keeping my hand planted on her hip. She did roll over and I let my hand slither over onto her tummy, just above her mound. I knew it was important to keep contact with her pelvis so she wouldn't lose her arousal. She looked so peaceful, her tits all splayed out, a hint of a grin on her face, I almost felt guilty proceeding with the massage, but I knew she'd be grateful in the end. As my fingers traced around her breasts, the movement in her hips became more urgent. Figuring it was now or never, I let one hand slip onto her nipple, while the other found the hood over her clit. "Yes!" she gasped, raising her head up off the mattress and opening her eyes wide. "Do it! Do it Bobby! I need it so bad!" I did what Mom showed me how to do, rubbing gently but firmly, until she was frantic to cum, bucking her hips in the air and thrashing her head back and forth. "That's it Bobby, that's it," she hissed, her voice getting higher and higher. I kept at it, the rhythm of my fingers pinching her tit matching the rhythm on her clit. "I'm so close," she whimpered, "so close." Moving to the other nipple did the trick, and suddenly her hips shot up into the air. She let out a staccato warble that matched the quivering of her body as she shook uncontrollably. When her hand darted down to push me away, I let up on her clit and watched as her moaning and gasping turned into a raggedy giggle. Of course, by this time, I was dying to cum, but with both hands full, all I could do was grin and bear it while my sis sputtered and drooled in an orgasmic euphoria. Just like with Mom, I had an irresistible urge to kiss her, hold her, feel her body writhing next to mine, but I sensed it wasn't time yet. All I could do was get her more and more sexed up and hope she'd invite me to join in. With this in mind, I slid to the bottom of the bed and shoved her legs wide open. "Oh God, Bobby, are you going to make me cum again?" "Yeah Sis, I'm going to make you cum all day if you want to." I kissed my way up her quivering thighs, savoring her tangy fragrance. When my lips reached her slimy slit, she practically jumped a foot off the mattress. "Easy Bobby, easy" she pleaded, grabbing a handful of my hair and holding my face about an inch away from her fragrant cunt. I was close enough to reach her with my tongue, so I laid a glob of saliva on her swollen clit and spread it around, waiting for her to mash my face into her pussy. It didn't take long, a minute or so, before she did just that. "Now Bobby," she moaned, as my tongue took up a rhythm similar to what I had done with my finger. As her hips began to undulate, I let my fingertip glide up and down her wet slit, which seemed to heighten her arousal. "Fuck me Bobby. Stick your fingers in. I need to feel you inside me." I slipped two in, and she let out a pitiful warble. I slipped in a third, and her warble turned to a guttural moan. "Fill me up Bobby," she commanded, her hips bucking wildly, her legs spread even wider. The fourth finger was a tight fit, but it seemed to be just what she needed. With a gasp and a shudder, she started cumming again, only this time it was more machine-gun-like; a quick series of spasms followed by a reloading period, followed by another series of spasms. My face was alternately shoved against her pussy, or held inches away while her whole body twitched and quivered. "Oh God, Bobby, I can't take any more. Please stop?" I rested my cheek on her inner thigh, licking delicately around the edges of her labia, while she wound down, her fingers still curled in my hair. As we lay together, I let her fragrance envelope me, much like the rays of the sun replenish a garden after a week of rain. It was like her pussy was the wellspring of life, and I was its servant, worshipping it with utter devotion. Finally, her fingers relaxed in my hair, and I was able to reach her slit for some careful licking and sucking. There was a lot of juice down there, especially trickling into the crack of her ass, and I wanted to drink it all. I pulled my fingers out from inside her sloppy pussy and started to spread her ass cheeks, when... "Mom?" "Alice?" I froze, realizing that Mom had just entered the tent. "What's going on here?" she asked, more in amazement than in anger. "He was just giving me a nonsexual massage." "Oh, is that what they call it now?" "Well," Sis whined, "it was supposed to be a nonsexual massage, but he took advantage of me." Abandoning the safety of the space between Sis's legs, I sat up, wiping my face on my T-shirt. "She's right Mom," I said. "I bet her I could give her a nonsexual massage, and she took me up on it." Mom just stared at us. "So," she intoned, in a calm but annoyed manner, "I'm guessing there's more to the ripped Speedo story than you've been telling me? Is that correct?" "Yes Mom," Sis said dejectedly. "I almost drowned exploring an old underwater truck when my Speedo got snagged, and Bobby saved my life by ripping the suit off me and sending me to the surface." "And?" "And then he demanded a hand job, you know, because I owed him, so I gave him one." "Thank you for telling the truth, Hon." Feeling a little left out of the discussion, I added my two cents: "I couldn't tell Mom, cause Sis said if I did, she'd cut my dick off in my sleep." "Okay," Mom said, looking like she was giving herself a migraine, "let me get this straight. Yesterday morning you got a hand-job from your sister, and then yesterday afternoon you had sex with me. How does that work, exactly? Do we take turns fucking you?" "I guess," I shrugged. "What?" Sis gasped, sitting up on her elbows, "you're screwing Mom too?" "That was when you left to get it on with Hank," I reminded her. "Oh my God" Sis groaned, laying back down and covering her face with the pillow. "He may be your brother, Alice, but he's also my son. Can't we agree on joint access?" "Mom!" Sis blurted from under her pillow, "this is totally fucked up. We can't both be fucking Bobby." "Why not?" "Well... I don't know. What do we do, make appointments?" "Appointments would work" Mom said, furrowing her brow in thought. "What about spontaneity?" "Spontaneity is good too." "I can't believe this is happening." "Well it is happening, Alice, so get used to it. Now, either move your ass over and make room for me, or take your nonsexual massage to your own tent." "Has he given you a nonsexual massage too?" Sis asked, in a small pitiful voice. "No," Mom snickered, "but he's giving me one right now." With that, she started undoing her belt. "Mom," Sis whined, "don't you know you're supposed to take a shower before a massage?" "You're right," she sighed, in a sort of fake giggle. "I'm on my way." She snatched Sis's robe from the bed and flounced out of the tent, slapping me on the back of the head as she left. "You're a sneaky little devil, you know that Bobby? You always were." After Mom left, I slid up on the bed and cuddled up next to Sis, "I'm sorry," I whispered. "It all happened by accident. When I came into the tent to get your bikini, Mom was asleep with a catsup bottle jammed up her cunt and a vibrator on her tummy, and later, when she realized I'd seen her like that, she wanted to talk about it, and one thing lead to another..." "You don't have to explain," Sis interrupted. "Just be honest. Which one do you like better?" "That's not a fair question Sis. You're both different." "All right then, who's pussy do you like better?" "Well, I haven't actually had my dick inside yours yet, so I can't answer that, can I?" "Jesus! You're such a manipulator!" She sat up and reached for my jeans. "Hurry up, before Mom gets back." She fished my stiff dick out of my pants, and ten seconds later, I was enveloped by a juicy pussy and a pair of cantaloupe tits, which should have made answering her question a little easier - but didn't.
