My thanks to him. This is the second plot idea he's suggested, and which I wrote, so he's on a roll. This story is written in two versions, one long and one short. This is the short one. The long one is titled "Packing Clarissa's Genes." The two versions were the result of reader input where some people said they liked short stroke stories and other people liked longer ones, with more character development and a slower pace. In trying to write a short stroke story I failed, initially. It turned into the above referenced longer story. So I tried again, using the same basic plot idea and this story was the result. So this one is supposed to be the stroke version. At least I think so. It's about a third as long as the first one I wrote. You, the reader, are the judge. Take a look at them both and see which one you like better ... assuming you like either one of them (grin). And please, let me know what you think. Bob ------- Chapter 1 Clarissa Davidson lay on her bed, staring at the ceiling. She was thinking about particle physics, which might seem odd for a sixteen year old high school student, but it wasn't odd for Clarissa. She was a genius, and was so far ahead of her classmates in the academic realm that it was like comparing a kindergartener to an eighth grader. You'd think that would have made her different than her peers in other ways too, but such was not the case. Smart she might be, but that didn't make life as a teenager any easier. They say that with the sweet comes the sour. That's just life. And Clarissa was fully engaged in life. She and her brother, Matt were just three and two years old, respectively, when they were orphaned. Their father's brother, Bob, was their only living relative and he took them in. He was the only father they remembered, really, but in honor of his brother's memory, he insisted that he was just "Uncle Bob." Their heritage was also present in their body makeup. Both their parents had been thin, and the children they produced seemed to be exact copies, physically. Neither had an ounce of fat to spare and Clarissa had been able to pass for a boy until she was thirteen. She hadn't even put on a top to swim in until Uncle Bob made her, when she was twelve. He said that even though it was only in the backyard pool, and even if nobody could see them, she was a girl and should act like one. That was difficult for her. She didn't feel like a girl, really. Even now, well into her teens, terms like "flat as a board" applied to her well. Some of the jocks at school had even teased her, telling her she was a "pirate's dream" and laughing. She had to find out from her brother that that meant she had a "sunken chest." That she coped with that kind of thing was because of her intelligence, though a strong dose of literal thinking helped. When Matt had told her a pirates dream was a sunken chest, she'd taken her top off and stared at herself in the mirror. "My chest isn't sunken," she'd said to her reflection. "I have bumps." In her mind, because her sixteen year old breasts rose from her chest a couple of inches, that meant that the jocks were wrong. That made them stupid, which meant that the fact they were cruel didn't really matter. She'd rather think about something interesting, like string theory, than concentrate on something a bunch of stupid jocks made jokes about. Her brain recognized that it was getting dark outside. That reminded her of a joke one of her science minded friends had told her earlier in the day: "What's the speed of dark?" She'd laughed, but she'd actually thought about it too. That was what set her apart from other teens her age. She wondered about things like what happened to all the photons that were already present in a room when a light was turned off? Where did they go? It was her turn to cook supper, though, and the coming darkness outside reminded her of that, so she got up. Her stomach growled just to punctuate the situation. She got things going on the stove and then went to set the table. She had to move four small boxes to do that. She knew Uncle Bob had brought them home with him, the night before, because she'd seen him come in with them. Being a curious girl, she opened one. It contained small squares, wrapped in plain pink waxy paper that looked a lot like Starburst candies. She pulled one out, unwrapped it, sniffed it, and then popped it into her mouth. It tasted like candy. The other boxes contained the same thing, except the paper wrapping was different colors, blue, green and purple. She tried one of each, thinking they must be different flavors, but they all tasted the same. Getting back to supper again, she took the boxes to the snack cupboard and put them there, next to a bag of chips. Then she continued to get supper ready. ------- Genius she might be, but Clarissa lacked what might have changed everything: experience. She didn't make the connection between the candies she had just eaten and the fact that her uncle ran a biogenetic company. She didn't make the connection between the fact that the wrapped candies didn't have a logo on them, and were in plain, gray cardboard boxes, instead of something devised by Madison Avenue. And, because she didn't make those connections, she was unaware that she had just taken a quadruple dose of a new drug her Uncle's lab was testing. It was called RD684 and it was supposed to help regulate the hormones of women suffering menopausal symptoms. It was a product of the cutting edge of stem cell research and, unlike compounds that contained synthetic estrogen and progesterone, it encouraged a woman's body to make the real thing. In short, it made a woman's body realize it was a woman's body. If there was a hormonal deficiency in that body ... it tried to correct it. And, before supper was over that night, Clarissa's body, undeveloped, in comparison to that of most other girls her age, and hampered by the weak genes her mother had given her, got a very shocking message from RD684. That message was "Baby, you are a woman, and we're going to make you LOOK like one!" ------- Over the next month Clarissa overdosed on RD684 on a regular basis. Her uncle would have been very interested in that - horrified ... but interested - had he known. He didn't, of course. That would come later. And, as so often happens when changes are relatively slow, the person being changed didn't notice it. Her brother did, though. "Hey Rissa," said Matt one day. Like his sister he was thin and pale. He didn't look sickly, exactly, but someone might assume he was recovering from some terrible illness. "Hmm?" Clarissa was reading a book by Stephen Hawking called "The Nature of Space and Time." "Did you change your hair?" She looked up and her eyebrows rose. She always wore her hair in a pony tail. "Are you having a stroke?" she asked. "It looks different somehow," he said. "I can't put my finger on it. Maybe it's more gold or something. It looks shiny too." Clarissa reached for her pony tail and pulled it in front of her eyes, which went crossed as she peered at it. She realized he was right. It DID look shinier. The strands almost felt silky in her fingers. And the color was deeper, warmer. She couldn't believe she hadn't already noticed it. "How about that," she said. "Beats me. Must be something dietetic." Matt came closer and leaned over to stare at her face. "Your skin looks darker too. Have you been sitting out in the sun?" "What sun?" snorted Clarissa. "It's winter, you dope." ------- Whether it was that incident, residing in the back of her mind, or that she was just less able to ignore the other changes in her body, over the next month she realized that her almost non existent breasts were growing. Drying off after a shower one day she looked in the mirror and her eyes widened. She had to look down to convince herself that what she saw in the mirror was real. Her breasts, which might have stuck out two inches in the past, were now looking rounded. Instead of bumps, she had humps. And the nipples were no longer just pink blobs. They looked like actual nipples! Her eyes took in the rest of her body. In the past, you could hang a string from her armpit and it would lie flat along her body all the way to her ankle. Not so any more. At first she thought her waist had shrunk. Then she realized that her hips had swelled. It wasn't all that much, but it was very noticeable to her. She still didn't make the connection between the two or three candies she ate each day after school, and the changes going on in her body. But she started keeping an eye on things after that. So did her brother. ------- "What?!" barked Clarissa, one night. Uncle Bob was working late and she and Matt were home together. They had rented a movie to watch and it was almost over. She was in her normal sleep wear, which was panties and a T shirt. Matt had on pajama bottoms with his T shirt. He'd been staring at her for most of the movie. "What do you mean?" he asked. "You're staring at me," she said. "No I'm not." "Yes you are," she insisted. "You've been staring at me for the whole movie. Why am I more interesting than the movie YOU picked out?" Matt was also very intelligent, though not quite on the same scale as Clarissa. His IQ was only 116, while hers neared the top of the charts. Like his sister, his circle of friends included only geeks. The female ones looked much like his sister had always looked. But she didn't look that way any more. "You have curves," he said, being polite. "Of course I have curves," she retorted. "I'm a girl." "You never had them before," he pointed out. "Duh!" she snorted. "Adolescence!" She glared at him. "And why are you so interested anyway? I'm your sister!" "True," he said, unruffled. "But you're starting to look like the women in my my..." He stopped and blushed. "Your what?" asked Clarissa. "Never mind," he said. "You're good looking, that's all." "Nice try," she said, sitting up. "Answer the question. Your what?" "You're not the boss of me," he said. He'd said that before, of course. Clarissa, being a year older and knowing she was smarter, bossed him around just like any older sibling might do. He resisted, even though he knew what would happen when he did. Perhaps, considering her recent physical development, he said what he said intentionally. If so, it worked. She bounded off the couch and they wrestled. They'd done this hundreds of times in the past. It was almost a ritual. He'd resist and she'd wrestle with him until she got the upper hand. Sometimes that upper hand was cerebral, rather than physical, because they were both pretty evenly matched, physically. It was all in good fun, though, and there was laughter and taunting as they fell to the floor and rolled over each other, each one trying to pin down a wrist, or get control some other way. Over and over she repeated her question: "Your what?!" But it was different this time. Matt was fully aware of the feel of her body, crushed against his. Those curves he had noticed were soft, where her upper body pressed against his, and more firm below her waist. Her T shirt rode up and his hands, seeking to tickle or pinch, landed on a butt that felt more full and round. It had always been somewhat bony before. He could still pinch, but he had to take a larger chunk of skin. He was distracted by the feel of her butt, and Clarissa saw an opportunity she always took if she could. Her fingers darted to his ribs and she tickled him mercilessly. "YOUR WHAT?" she shouted. He was almost helpless. She won this way quite often, and today was no different. "MY PLAYBOY!" he shouted. She stopped suddenly. "You have a Playboy?" She asked it in the same way she might have asked "You've grown a third arm?" "Uncle Bob said I could have it," he panted. She had stopped and he was surreptitiously moving his fingers for a counter attack. "He did?" She sounded amazed. "Why would he do that?" Matt struck ... or thought he was striking. Things got a little mixed up. Thinking about his Playboy made him think about the breasts of the models he stared at as he beat off. He'd always wanted to feel a girl's breasts, but that was a little like wanting to walk on the moon. Maybe someday. And so, when his fingers darted to tickle her, they somehow ended up dancing all over her breasts. His touch was light, and consisted of both poking gently and stroking. For Clarissa, awareness of the change in their play came when her nipples communicated with other parts of her body. They tingled and an almost electric jolt of pleasure shot to her brain. She froze and looked down to see her brother's hands cupped over her breasts. She watched them squeeze, and felt the tingles again. "What are you doing?" she asked, a little breathlessly. "Tickling you," he answered, squeezing again. "No you're not," she said. "You're feeling my boobs!" "I guess so," he sighed, unashamed. "I'm sure glad you grew them." "You're a pervert!" she squealed, leaning back and breaking contact with his hands. "No I'm not," he said, staring at what he'd so recently felt. They felt wonderful, as far as he was concerned. "I'm a guy. All guys love boobs." "Not their sister's boobs," she said. "Why not?" he asked. "It's not like I'll ever get touch anybody else's." "Why do you have a Playboy?" she asked. "Well duh," he smirked. "I thought you were supposed to be the genius of the family." Understanding came, slowly at first, and then, because of what she was currently sitting on ... which was his groin. Something moved under her butt. She scooted back automatically to see what it was and stared at the lump forming in the front of his PJ bottoms. "You MASTURBATE?!" Again, it was as if she were asking something like "YOU GREW A THIRD EYE?!" "Uncle Bob said it's normal," said Matt, who didn't quite know how to feel about the fact that his sister was staring at the front of his pants. The male in him decided she was female, and that was all that mattered. He got even harder. "He said that sexual feelings can be very distracting for a boy, so he told me it was OK to get rid of them by beating off." "Wow," said Clarissa. She'd never thought of her brother as a sexual being, even back when they swam topless. And she'd never thought of her uncle as a sexual being either, even though she thought he was handsome. Her eyes opened wide. "What about me?!" "What about you?" asked Matt. "Uncle Bob never told me I could masturbate!" "You're a girl," snorted Matt. "Girls don't have the same distractions as boys do. Everybody knows that. That's why they won't let boys do stuff on a date." "You are singularly unequipped to discuss what happens on dates," said Clarissa. "OK, smarty pants. When was the last time you got horny and wanted to masturbate, but couldn't because you didn't have permission?" "That's stupid," said Clarissa. "All right. When was the last time you were horny and wanted to masturbate at all?" "I don't know," said Clarissa, feeling uncomfortable. The fact was that she wasn't sure she'd EVER been horny, and she'd certainly never thought about masturbating. She knew the practice existed, but didn't understand why anybody would feel the need to do it. She diverted attention from that by asking him "How often do YOU get horny and masturbate?" He took her question literally. "Some days it's four or five times. It all depends." "FOUR OR FIVE TIMES A DAY?!" she squealed. "It only takes a couple of minutes," said Matt. "It's no big deal. I get hard. When that happens I look at the boobs in my Playboy and the next thing I know I'm spurting all over the place." She covered her eyes with one hand. "More information than I needed!" she announced. "Well you asked," he said. She uncovered her eyes and looked down. The front of his PJs was fully tented out now. "You're hard now," she whispered. "Yeah," he agreed. "Why?" "Promise you won't hit me if I answer?" "Why would I hit you?" "Just promise, OK?" "OK, I promise. "Because I felt your boobs," he said. "You're hard because of MY boobs?" She was amazed. "Yup," he sighed. "I bet they look just as good as the ones in my Playboy." All kinds of new emotions flittered through Clarissa. They made her want to cry and laugh, all at the same time. She didn't know HOW to feel. No boys had ever noticed her before, at least not in a positive way. And that had stung, even though she didn't dwell on it. Now, the first boy TO notice her as a female ... was her brother. The brother who masturbated while looking at pictures in a Playboy. The brother who thought her breasts might look like the ones in that magazine! She had much to think about and, in true academic fashion, she just stood up and walked away to do so. It was late enough that she just went to bed. Matt got up too. He went to bed as well. But he didn't pull out his Playboy this time. He just closed his eyes and remembered the feel of Clarissa's boobs as he stroked his hard cock. He spurted within a minute. ------- The reason their Uncle was working late that night was because of a new side effect of RD684 that had just been discovered in the clinical trials going on. It made the women horny. There was no other explanation, really. Most of the women in the study were over fifty and all had reported that their interest in sex had been steadily lessening over the years. Some women in the study hadn't had either a period or sex in over a year. All of them were now saying that their interest in sex had revived. Bob and his crew were trying to figure out if this was a problem or not. Most people would have laughed at the idea that a sex drive could BE a problem. But some of the women reported that their newly returned desires were stronger than they'd been in years and years and years. One woman said she kept thinking about her honeymoon, back when she couldn't get enough. She said it was like that now, and her husband was not able to keep up with her. Of course, Clarissa didn't know about that either. ------- Another month passed. When she first found them, two months earlier, the boxes of candy had each had ninety pieces in them. The test packaging had been based on a dose of one per day, and a ninety day supply. Eating two or three a day had depleted one box completely. The pink ones were all gone, and there were now only thirty of the yellow ones left in their box. Clarissa had thrown the first box away when it was empty. It would have been good if Bob had seen that box in the trash ... but he didn't. The fact was that Clarissa had consumed a hundred and fifty doses of RD684 in sixty days, or about two and a half times the normal dosage. Of course ... she didn't know that. What she DID know was that her breasts kept growing. They got rounder, and heavier. She noticed that they bounced now, when she ran or jumped. She'd never worn a bra before. She'd never even owned a bra before. Even now she wasn't sure she wanted to get one, because the way her nipples scraped against the fabric of her tops felt delicious. And Matt kept staring at her. It had bothered her at first, but only because he was her brother. Then she realized the fact was that his attention made her feel good. Guys at school were paying more attention to her too, but that was different somehow. She knew Matt liked looking at her chest, but he also cared about her. He'd talk science with her. When she was unhappy about something, he tried to help. The guys at school liked looking at her chest ... but that was about it. Then there were the feelings. Lately she felt full of energy all the time, even at bedtime. She felt jumpy ... or itchy ... or something she couldn't quite give a name to. She thought about it a lot, and she always came back to what Matt had said HE did when he got distracted ... horny. She wondered if she was horny too. On another night when Uncle Bob had called to say he'd be late, she thought about talking to Matt at supper. It was harder than she thought it would be. They'd talked about all manner of things before, but this was ... embarrassing. It was Matt's turn to fix supper and clean up and she watched him fiddling with the pots on the stove and setting the table. She didn't even realize she was moving around as she did it. "Quit pacing. I'm working on it," he complained. "Sit down, or something. You're making me nervous. The potatoes need another ten minutes and then we can eat." Idly she went to the snack cupboard and got a candy. She was unwrapping it when Matt saw her. "Where'd you get that?" he asked. "Don't spoil your supper." "One isn't going to spoil anything," she said, testily. "It's just a little piece of candy." "I didn't know we had those," he said. "Get me one too." Clarissa grumbled to herself about how he told her not to eat one, and then asked for one himself. She got one out and threw it at him. "What's wrong with you?" he asked. "What did I do?" "Nothing," she said. "Eat your stupid candy." He did. "Not bad," he said. "Toss me another one." "I'm not your slave," she said. He went to the cupboard and got a handful. "Now who's ruining who's supper?" she asked. ------- As they were eating Matt finally spoke. "You want to talk about it?" "About what?" she replied. "About whatever has you grinding your teeth." She thought about that. She wanted to talk to him, but she was scared. "You'd just laugh at me," she mumbled. "Not if you don't want me to," he said. She looked up at him. Both his voice and his demeanor said he was telling the truth. She felt a wash of warmth slither through her body. Whatever was going on, it wasn't his fault. And he did care about her. "I don't want you to," she said. "OK, then, I won't." She waited two whole minutes before she said anything. "What does it feel like when you get the urge to ... you know ... with your Playboy." She watched for the grin that would signal he was breaking his promise, but it didn't come. "Mostly I just get hard," he said. "I mean when I get hard, I know to do it." "But how do you feel when you're getting hard?" "Oh," he said. "You mean what GETS me hard." "I guess so." "Lots of things," he said. "I get hard when I think about certain girls at school. I get hard every time I go into Ms. Jakowitz's class, but if you tell Uncle Bob I'll swear you're lying." "I'm not going to tell him," said Clarissa. "You can't do that at school, though." "Yeah," he said. "That's when I spend the whole afternoon horny and I beat off as soon as I get home." "What does horny feel like?" she asked. He looked at her and raised his eyebrows, but he didn't laugh. "I dunno. I get all anxious feeling, I guess." "Like you have all this energy and it won't come out?" she asked. "Yeah, like that." "And you can't concentrate?" "Yeah, that too." "Matt..." she gulped. "I think I'm ... horny!" He put his fork down. "You THINK you're horny?" "Lately I feel like I'm going to just burst if I don't do something, but I can't tell what it is that I'm supposed to do. I can't sleep. I get these itchy feelings. I think about you masturbating!" "You're horny," he said firmly. "This never happened before?" "No!" she moaned. He leaned back. "Well, it's really no big deal. I mean I take care of it all the time ... you know." "But I don't know HOW to take care of it," she whined. "How did YOU learn?" He blinked. Then he smiled, but she could tell it wasn't about her. He was remembering. "I was in the shower one time, and my penis got hard while I was washing it. It felt good to keep washing so I just did. Pretty soon I got this crazy feeling that was like a pain, but it felt good, so I just kept going. Then it got REALLY painful, except I couldn't stop then and stuff squirted out of my penis and I felt WONDERFUL." He blushed. "I thought I'd hurt myself at first, but my penis got all soft again and everything just felt good. The next time I got hard, I did it again and ... I guess that's about it." "I don't have a penis," she said mournfully. "I don't know what to do." Matt looked around, as if he expected somebody else to be there. "If I tell you something, do you swear you'll never snitch on me?" Her big sister radar flicked on, but he HADN'T laughed at her and she knew this was important, somehow, so she nodded. He leaned forward. "I was fooling around on the internet one time and I got this porn site." She couldn't help herself. "You know Uncle Bob said not to do that!" "I know," he admitted. "But it just popped up, and I was curious. I took a look and then I got rid of the cookie so he wouldn't find out." "OK," she said. "Well, the thing is ... they had videos on there ... and some of them were of women masturbating." "Get out!" she said. "No, really! They were doing it. They were rubbing between their legs. Remember how we learned about the clitoris in sex ed, but they didn't say what it was for? Well, on this video, they were rubbing that like crazy and sticking fingers in their pussy and moaning about how good it felt and everything!" She looked confused. "But when I have my period I put a Tampax in and it never felt good!" "I guess it's different when you rub around down there," he said. "I don't know. It's just way different than what guys do." She bit her lip. "Could you ... show me?" "Show you what?" he asked. "How they do it, stupid!" His eyes widened. "They were ... um ... naked. So ... would you get naked too?" She blushed. "I guess." "YES!" he gasped. "I can do that!" ------- Chapter 2 She'd agreed to getting naked for two reasons. First, the thought of it made that pressure flood into her chest, and her nipples started tingling. Second, she thought about how they'd swum topless all those times. This would probably bee pretty much the same. It wasn't the same at all, though. She watched him watch her, noting his wild eyes as she took her top off first. His tongue almost fell out of his head as he stared at her breasts and, for the first time, all the tingles in her nipples seemed to spread until she was tingling between her legs too. Then he started taking his clothes off too. "What are you doing?" she asked, her thumbs in the waistband of her panties. "I'm gonna have to do it too," he panted. "There is no way in the world that I can watch you do this and not do it too." "Oh." She finally got to see what made that huge tent in the front of his PJs that night. It had the peculiar effect that a cobra has on some people. It was beautiful and fascinating to look at, but it also scared her half to death. His hand grasped it, though, and began to stroke up and down. He was clearly in control of this beast, and she relaxed. "What do I do?" she asked, eager to do something. "I can do this standing up, but you should probably lie down," he panted. She did and then had to work up the courage to spread her legs as he got into position to see. When she finally got her knees apart, the look on his face made her legs feel weak and they just splayed open limply. There was adoration in his eyes. "Oh wow," he sighed as he got his first look at a pair of real live pussy lips. Hers looked different and similar at the same time, compared to those he'd seen on the internet and in magazines. Hers were closely pressed together and pale. He couldn't see inside her at all and they closed protectively over the area where he knew her clit was. Not thinking about how she might interpret it, he kneed up on the bed, still stroking his prick slowly. "What are you doing?" she asked. Her voice wavered. "I'm going to show you," he said, already thinking that he was going to get to touch that pussy as he pried those tight lips apart. "I'm going to show you where to rub." To be honest, things would have stopped right there, had it not been for RD684. Clarissa would have chickened out. But, as the drug was responsible for this whole episode in the first place, it was also responsible for Clarissa's decision that letting her brother touch her was no big deal. After all, it was for a good cause. If she didn't find some answer to this jittery feeling, she was going to go crazy. He had to abandon his penis as he got down on his elbows. She lifted her head to watch as his face and hands got closer and closer. She told him to wait and she reached for a pillow to fold in half and support her head and neck with. Then, almost in slow motion, his fingers reached for her. His first touch was almost like someone feeling a pan on the stove, to see if it's hot or not. Then, with opposing fingers, he pried her sexual lips open. He started in the middle, and then worked up until the sheath that covered her clitty was exposed. The little organ was apparently hibernating, at the moment. "See that bump?" he asked, staring at it in wonder. "Uh huh." "That's it." "That little thing?" She sounded almost disappointed. "Why do you get a big long penis and all I get is a little bump?" "Can I touch it?" he asked. Clarissa thought it was pretty funny for him to be holding her apart down there and ask if he could touch her, but she gave him the OK. Within seconds she was delighted that she had. His finger was dry, and so was she, so the skin that he touched and pushed stretched as he pushed his fingertip across that little bump. "UH!" she gasped explosively as a jolt of pleasure shot through her belly. And all he'd done was just touch it! Matt was both delighted and curious. He'd forgotten his prick in the fascination of exploring this entirely new kind of thing. His experimentation was really just curious play, a little like finding some strange new bug and poking at it to see what it will do. His fingertip circled the bump. He was rewarded with a sigh. He did that again and her hips started moving up and down. "They rub it like this," he said, continuing to circle the sheath. Before his eyes it opened, just a slit at first and, amazed, he watched something begin to push out from within. Part of his astonishment was that what pushed out of her body actually looked a lot like the head of a tiny penis. It wasn't hard, though ... not in the sense that his penis got hard. He flicked it sideways and it bent easily. "HUUUUH!" grunted his sister. Grinning he started pushing the protrusion this way and that. Her knees bent and she started pushing with her heels, raising her hips as he mauled the little organ. Then, just for fun, he tried to press it back inside. Clarissa whined then and the tone and timber of her whine reminded him that he had a hard dick to stroke. "Now you rub it," he said, getting to his hands and knees. Her hand slid into her crotch and one finger found the button immediately. He watched, interestedly, as she did things to it that looked much rougher than anything he'd have contemplated doing. Then he remembered how hard the women in the videos had rubbed. Some of them had even slapped it! He got to his knees and started jerking his cock while she continued. She got noisy and he could actually see the moisture begin to flood her fingers. He kept telling her what to do, describing what the women on the screen had done. When he told her to slide a finger inside, and she did, his prick erupted. A rope of cum lanced out of his prick and painted the back of her finger as she slid it out and back in. His prick spat again and again, getting her hand messy with his juice. He watched and his balls seemed to twist as he saw his white spunk being pressed into her pussy. She began using three fingers, flat, whipping them back and forth across the bud, violently. She gasped that something was happening that felt scary but good. He told her that was OK and to keep going. Her scream of completion almost got him hard again. He couldn't tell if she was crying or laughing, though, and he remembered how scared he'd been the first time this had happened to him. So he collapsed beside her and pulled her into a tight hug. The feel of her naked skin against his was fabulous, but it was just a side effect. What he was doing was just hugging her. She hugged him back as she calmed down and caught her breath. It was quiet for a long time until her breathing returned to normal. They just held each other. "Better now?" he asked softly. "You have noooooo idea," she sighed. "Yes I do." Her head moved and she stared at him, almost nose to nose. "I guess maybe you do." Then, for no reason, and every reason, Clarissa kissed her brother on the lips. ------- Twenty-five or thirty kisses later, nature and RD684 resulted in Matt squirming on top of his sister while they each tried to push each other's tongues back in their mouths. Her legs were spread and it was all fairly innocent at first. It just felt good to rub their genitals together. Then the tip of his prick caught in her virgin opening. He shifted sideways and it came out, but it got caught again. The fourth time it got caught, he pushed with his arms, until he could stare at Clarissa's face. No words were spoken. They stared at each other as he pushed ... just a little. Her calm eyes just gazed into his, so he pushed ... just a little more. Her eyes widened when the head of his prick popped inside her stretched labia, but she didn't tell him to stop. When his prick was halfway in, she took her lower lip between pearly white teeth and bit it gently. This was, of course, new territory for both of them. For Matt it was surreal as he slowly pushed deeper and deeper, feeling like he might go in forever. When the wisps of his dark brown pubic hair mingled with her lighter fluff, his inclination was to keep pushing, because he WANTED to go in forever. For Clarissa, the feeling of something hot and hard spreading her apart was a mingling of pain, from which fear bubbled up, and an incredible sense of well being, which shushed the fear and only anticipated being even more full. Then, when he was in as deep as he could go, and KEPT pushing, the little swollen organ she had so recently discovered, seemed to sing a note that vibrated throughout her body. At that instant, she knew this was meant to be. It was perfect, and her joy exploded as a surprisingly calm orgasm just shivered through her body. "Ohhhh yesssss," she moaned. "Matty, I love you so much." It was a surprisingly tender moment for Matt too. All the fucking he'd seen in his secretly watched videos had looked violent and forceful, with people screaming and bodies flailing. He could not have been prepared for how intimate this was ... for the feeling that he had somehow become part of his sister's body, and she his. And her confession of love came at the precise time that he realized what a precious thing she had let him do. He would forever be thankful to her for that gift, and emotion surged out of him too. It wasn't in words, though. He simply dripped hot tears of happiness on her cheeks. Then her body took over, trying to extend that luscious gentle climax, and her hips arched. Matt reacted by rising with her, just as she fell back. It pulled half his prick from her molten sheath. Her hips rose again as he corrected and moved down and ... just like that ... they learned the ancient dance of the two backed beast. What had been sweet, slow lovemaking, took on an urgency until, if he'd been able to think about it, Matt would have said looked exactly like what he'd seen on the internet. Within a minute he was lunging into her and she was slamming her loins up to meet each lunge, panting "Yes!" over and over, hoping it would never stop. It had to, though, because Matt was on overload. His body ached to breed and he wasn't in control of it in any way, shape, or form. His hot jets of semen began while he was still lunging, and the first three jets coated her entire vaginal tube before instinct made him slam forward and freeze as his body pumped four more thick streams of baby makers against her cervical mouth. Clarissa's initial cum HAD been extended as he began to move in and out of her. She'd felt like there might be another one out there and had been trying hard to find it. She hadn't yet, when his croaking cry of completion told her something important was going on. Then, it didn't matter, because she watched his face twist into a grimace that could only be agony, except that his groans were undeniably joyous. He looked like he was dying as she felt that beautiful penis buck and jerk inside her and the hot, wet ball of fire enter her core and begin to expand. She could have cared less that she didn't cum again, because watching Matt cum was just ... well ... almost as good. ------- The aftermath wasn't strained or sad in any way. Both teens had recognized how very special this kind of relationship was and it was impossible for either of them to perceive it was being harmful. Something that beautiful just couldn't be bad. There was some kissing, but few words as they caught their breath and Matt lay on top of her. He asked if he was heavy and she said he wasn't. Both knew the other was OK. And both knew they'd do this again. "I can't believe I'm hungry," said Clarissa suddenly. "We just used a lot of energy," said her brother. They got up and put on their sleep wear before going to the kitchen for a snack. While Clarissa made peanut butter sandwiches, Matt munched on four more candies. He unwrapped another one and put it between her teeth. Ten minutes later, an observer would have seen two teens, watching TV, dressed for bed, and wouldn't have been able to see anything unusual about them at all. If the observer would have stuck around another ten minutes, though, it would have been more interesting. "Did Uncle Bob say when he was going to be home?" asked Matt. Clarissa had taken their uncle's earlier phone call. "He just said not to wait up for him," she answered. "Why?" He looked at her with no trace of embarrassment. "I have another boner." ------- Bob sighed as he got out of the car. It was late and all the lights were off, so he was trying to be quiet. He was tired. He'd be glad when the RD684 trials were over and the data sent to the FDA. He felt bad because he had been spending so much time with work related issues that he felt like he'd abandoned his niece and nephew. He knew they were OK. Both were smart kids and they understood about his work, but he still felt bad for not spending more time with them. He stopped at Clarissa's room to look in on her. The light from the hallway into her darkened room showed that her bed was empty. That was strange. There had been no lights on at all when he got home. He backtracked to the living room, thinking she might have fallen asleep on the couch, but she wasn't there either. He looked at the dry erase board on the refrigerator, but there was no note about a sleepover at one of her friends' houses. A little worried now, he went back to the hallway and pushed open Matt's door. He was frozen in place by what he saw. Matt and Clarissa, like newlyweds finally allowed to be together all the time, had spent hours in each other's arms, rubbing together as they overdosed on the sex they had just discovered together. Neither had meant to stay naked, and neither had intended that Clarissa stay in her brother's bed, but sexual exhaustion had finally claimed them. What was revealed to their uncle's eyes was the result of that sexual exhaustion, though it was slightly misinterpreted, at first. Matt was lying beside some girl Bob had never seen before. Bob's mind casually classified her as a cheerleader type, based on the long blond hair, hour glass shape and grapefruit sized breasts. The girl was on her back, with her face turned toward Matt. His arm was thrown across her, his hand resting lightly on her left breast. The room smelled of sex, something Bob hadn't sniffed in more years than he wanted to remember. Even in the dim light admitted by the open door, the gooey mess that was between the girl's legs bore testament to the fact that no protection had been involved in their tryst. Bob was of two minds. He was surprised that Matt, thin and geeky had managed to score with such a voluptuous young woman. At the same time the fact that, unless the girl was on the pill, they'd had unprotected sex, was worrisome. Matt should be smarter than that. The girl moved and her face turned away from Matt and toward Bob. Bob started to duck back, in case she opened her eyes, and then froze again as his tired mind registered the fact that this was no strange girl. It was Clarissa! He stared, in shock. Where was the skinny little girl he knew so well? When had she matured to much? And what was she doing in bed with her brother?! Bob's mind, already tired, almost shut down under the visual assault. His neglect of them had driven them to this. Less than popular geeks, with not many friends and nothing to do on date night, they had depended on him to entertain them. In his recent absence they had found ... other entertainment. He didn't know what to do. He could wake them up, but there would be yelling and nothing could be solved. It was already too late for that. He knew what he was SUPPOSED to think about this incestuous coupling, but he didn't feel that way. He wasn't sure how he DID feel, but he wasn't disgusted. He realized that his eyes were still moving from her breast to her sperm-filled pussy and back again. His own dick was as hard as stone. He didn't know how to feel about that either. In the end he left them there. He left the door open, so they'd know he'd seen them. Then he went to bed. He had to jack off before he could get to sleep. Visions of Clarissa's pussy, overflowing with her brother's seed, danced in his head. As he came, he felt guilty that he wished he was adding to Matt's offering of love to the girl. ------- Clarissa woke and realized what had happened. She sat up suddenly and looked at the door. What her uncle had wanted to happen did. She knew that they had been seen, here in bed together. She shook Matt violently. "Wake up!" she whispered harshly. He did and looked around blearily. His eyes registered his naked sister and he smiled. "Uncle Bob knows!" she said, her voice full of fear. "What?" "I closed the door last night. I know I did," she said. "Look at it now!" "Why are you still here?" asked Matt. "I thought you were going back to your own room." "I fell asleep, you idiot!" she snapped. "Don't call me an idiot. I love you." He sounded injured. "Don't you get it?! He KNOWS!" "I can't believe you have a bigger IQ than me," he said. She blinked. "What? What are you talking about?" "We're still here ... together ... right?" It was so obvious that she didn't even nod. "So if he really DOES know, then he didn't get all freaked out about it." "That can't be," she said, looking uncertain. "Then maybe he doesn't know." "But I closed the door! I know I did!" "I don't remember anything except..." He grinned and reached for her breast. She slapped his hand away and got up. All she had to put on was her sleep wear, so she did that. She left Matt there and went to the kitchen. She didn't know what else to do. She finally decided to go take a shower and get dressed. When she was finished in the bathroom she went back to the kitchen. Uncle Bob was there this time, standing at the stove cooking bacon. She didn't know whether to go in or run away. She was saved from having to decide which when he looked over his shoulder. "Want bacon, or just eggs?" "Um ... both, I guess." "Is Matt up too?" She had no idea what to say. She blushed. When she didn't answer he looked at her again. "Was he awake when you got up?" "Uncle Bob," she said, her voice pleading. "We..." He cut her off. "It doesn't matter. I know he'll want bacon. I'll just cook it and if he's late he'll have to eat it cold." His response astonished her. He wasn't yelling. He obviously knew and he wasn't yelling! She sat down. He didn't say anything as he served her and then himself. He sat, eating. After five minutes, during which he cleaned his plate and she just moved her food around with her fork she couldn't stand it any longer. "Aren't you going to yell at us?" He looked up from his plate. "Would it do any good?" She didn't know how to answer that either. "We need to get you on the pill," he said. "That's the main thing." She was astounded. "I don't understand," she said softly. "I'd rather you'd waited to become sexually active," he said. "But it's too late for that. What you really don't need is to get pregnant. So we need to make sure that doesn't happen." "You're being so CALM about this!" she moaned. "I don't understand why!" "You're growing up," he said. "I don't know how I missed that, but you obviously are. And once Pandora's box is open, you can't close it again. I was young once, and I remember. I can see why Matt was interested. And I think I understand why you chose each other. As crazy as it sounds, I think I'd rather it be this way than have you running around with strange boys I don't know, who don't care about you other than for ... that." "It was an accident," she said, unable to resist defending herself, even though defense wasn't needed. "What I saw was no accident," he said, unable to resist making his point, even though he had decided not to overdo his response. "But it was!" she insisted. "I had these strange feelings that I didn't understand and Matt explained it was because I was horny. I never felt horny before and he was trying to teach me to masturbate and things got crazy and..." She finally stopped talking. Bob sighed. "Believe or not, that actually sounds logical ... considering that it's you two we're talking about. It just never occurred to me that you might need help in that ... um ... arena. I haven't been a very good father figure." "Yes you have!" she yipped. "Not if you had to ask your brother to help you learn to do something like that," he said. "I'd have asked you ... but you weren't there," she said. "I'm glad you didn't," he sighed. "If you had ... based on how I felt last night ... well I'll just repeat that I understand why he was attracted to you." His meaning sank into her brain like a small bomb that exploded, but didn't destroy anything. She knew Matt had gotten horny for her, and she was actually used to that idea now. But Uncle Bob too?! ------- The atmosphere in the house was unalterably changed after that. Bob took Clarissa to the doctor and got her a prescription for birth control pills. He discussed the importance with her about taking them regularly, which the doctor had also stressed. Bob also explained how they worked, which the doctor hadn't done. For Matt and Clarissa, things were tumultuous for a few days. That was because their uncle didn't tell them what to do. Matt argued that he hadn't ordered them to stop. Clarissa said he was an idiot of he thought that meant it was OK to go on doing it. For Bob, it was impossible now to look at Clarissa and not think about the fact she was sexually active. Her astonishing physical maturity was impossible to ignore too, now that he was aware of it. As a consequence, he looked at her as a woman now. Clarissa noticed that. It fit with what he'd said about knowing why Matt would want her. Now both of the men she loved made her feel special and sexy when they looked at her. ------- The sexual tension in the house built steadily over the next few weeks as the teens both continued to consume overdoses of RD684. While no one at Davidson Biotec had thought about it, RD684 worked the same way in males as it did in females. If there was a hormonal imbalance, the drug sought to correct it. Matt began to build muscle, and his beard and other body hair began to grow faster. His testicles and penis grew too, though to a lesser degree. What was in his balls became richer and more virile and his sex drive, already healthy, increased. Clarissa's breast growth continued, though at a slower rate. Her ovaries and associated organs were now at peak health and the strange urges she felt became less and less strange as "horny" became the norm, rather than something new. Bob kept trying to ignore what the youths had discovered together, but it was impossible for him not to think about his nubile niece, no doubt moaning and groaning as her brother thrust his hard prick deep in her belly. He masturbated more, these days, than he ever had in his life. The teens, trying not to make their liaisons obvious to their Uncle, attempted to assuage their desires when and where they got a chance, which meant they tried to schedule when they'd be horny. In other words, whenever Bob wasn't around, Clarissa and Matt were naked, rutting in bed, as each strained to satisfy a lust that seemed to build, rather than go away. It wasn't unusual for Clarissa's wide spread and sucking pussy to gulp down three or four loads of Matt's thick, warm spunk every day. The breaking point came when Matt went on a camping trip with some of his friends, leaving Clarissa and Bob alone. Clarissa's need for a bra had become both obvious and immediate. She did the research on the internet, but she had to have help taking measurements to plug into the calculation for her proper bra size. She asked Uncle Bob to help and, when she took off her top to facilitate the measuring process, Bob finally lost it. She was shocked when he suddenly leaned forward to suck at a stiff nipple. But Matt had never done this particular thing to her before, and her shock gave way almost immediately to a burst of lust that was only inflamed when she saw the lump in the front of her uncle's pants. How they got naked, neither of them would be able to remember. But both would remember the first time he slid his aching adult boner into her quivering teen pussy. "Mmmmmm, you're bigger than Matt," she murmured. Her words were only the latest signal that she was completely receptive and, in the animal kingdom, a receptive female affects all males the same way. It had been a long time for Bob and her purr of approval unleashed the first of what would be four seminal offerings she got that night. Bob was more astounded than she was, which wasn't strange, since Matt could go five times in a single night. What DID astound her were all the different ways Bob taught her make love that night. She and Matt had only done the missionary and cowgirl positions. Bob taught her doggy style, the spoon fuck and how to fuck standing up in the shower. He also taught her oral sex, which neither teen had been willing to try before this. She became almost instantly addicted to the feel of a hot, hard prick in her mouth and the joy of feeling a tongue bathing her clitty. She didn't learn what semen tasted like, though. Since she was on the pill, Bob deposited every drop of that in her sperm bank. By the time Matt got home the next evening, Clarissa had two lovers, and all pretense at hiding anything had evaporated. Clarissa set up her own schedule. One night she slept with her brother, and the next she spent in her uncle's bed. Within a week both men were happy they only had every other day access. Clarissa would have been quite happy fucking all day and all night. She was wearing them both out. ------- Vanessa, one of the researchers on Bob's staff stuck her head in the office door. "Bob, we may have a problem with RD684," she said. Bob groaned. "What now?" The fact that the experimental menopause drug seemed to increase the sex drive of the women taking it had already caused a major uproar. "Mrs. Jenkins and Mrs. Abernathy are both pregnant." Bob's eyebrows almost rose into his hairline. "What?! I thought all the volunteers who might still be fertile were using birth control!" Vanessa shrugged. "Both are in the early stages of menopause," she said. "Both were taking the pill. Mrs. Abernathy said that she and her husband hadn't had sex for six months until she got in the program, but she went back on the pill at our request." "But if they were on the pill how did this happen?" "Apparently the drug brings about a spike in estrogen during their menstrual cycle. It counteracts what the pill is supposed to prevent. With that spike, if there's an egg left in the ovaries, it gets released." "Shit!" Bob exploded. "It's not the end of the world," said Vanessa. "We just have to reserve it for use by women who are known to be infertile. All women run out of eggs sooner or later. That's what starts menopause in the first place," she said. "This kind of thing would be very rare side effect." "We can't say it's rare if two of our test subjects suffered it!" moaned Bob. "And the whole point of RD684 is to mitigate the symptoms of menopause. It's quite common for those symptoms to take place up to a year before a woman is actually IN menopause!" "We'll just have to recommend some form of contraception other than the pill," said Vanessa. ------- Bob was frustrated by the setbacks in the trials for RD684. The increase in libido might not be considered a problem by most people, but the pregnancy issue was a big one. There aren't many fifty and sixty year old women who want to have a baby, and even if they do, it's hard on both mother and child at that age. And so, he may be forgiven, perhaps, if his desire to think about something other than work rose to the surface when he got home. It was easy to forget the frustration while kissing and stroking and fucking his nubile teenage niece. He groaned as his balls gave her another healthy dose of sperm-laced semen and her pussy arched up to receive it. "It's so good to cum in you, baby," he moaned as his prick bucked and spat her belly full of cum. "It's so good to feel you cumming in me," she whined as her pussy milked every drop of sperm from his prick. They lay, cuddling afterwards, and he sighed. "I'm going to have to stop doing this within five minutes of getting home. It's getting in the way of supper and I'm starved." "Matt's making supper tonight," she whispered. "Stay right there and I'll get you a snack." She hopped out of bed, reaching to seal his semen inside her by closing her pussy lips together with two fingers. Running around the house naked was completely normal these days. It wasn't unusual for her to be bedded twice before bedtime, and being naked both led to that and made it easier. She laughed at the look on Matt's face as she got a candy and ran back out of the kitchen. She couldn't peel it, and press her pussy closed at the same time, so she just handed it to Bob when she got back. "Eat that," she said. "It will take the edge off. Supper should be ready in ten minutes." Bob took the candy from her and stared at it. "Where did you get this?" he asked. "From the snack cupboard," she said. "The snack cupboard?" "There were several boxes of them on the dining room table. I put them in the cupboard where they belong," she explained. Bob felt faint. He'd forgotten about the samples completely. "You've been eating these?" he croaked. "Uh huh," she said brightly. "I like them too. We need to get more." Her casual comment had bob bouncing out of bed and running, naked, to the kitchen. Matt and Bob didn't run around naked as much as Clarissa did, so Matt was surprised when his uncle ran into the kitchen, followed by Clarissa who was still naked and still holding Bob's sperm in her pussy. In what looked close to panic, Bob tore open the doors to the snack cupboard. His hand darted in and came out with three boxes of candy. "Where's the other one?" he gasped, opening the three boxes. There were only a dozen pieces left in one box. "We ate them," said Clarissa. "Why? What's wrong?" Bob stopped, frozen. "WE ate them? You and who else?" "Matt, of course," said Clarissa. "What's WRONG?" She was starting to sound scared. "It's not candy!" he groaned. His mind flickered through the math necessary to provide the information that, even if both of them had eaten the RD684, there were overdose concerns added to the initial problem of young people taking the drug. He had no idea how that would affect a young woman, and even less than no idea how it might affect a male. ------- Dr. Fisher came out of the exam room and approached Bob. He was a friend of one of the physicians involved in the study. His friend had briefed him on what the study was about. Dr. Fisher had agreed to examine both teens, since he could keep the findings confidential, if necessary. "They're fine," he said. Bob gave a huge sigh of relief. "That's the short story. But there do appear to have been some side effects." "Such as?" asked Bob, anxious again. "Her physical maturity is closer to a chronological age of twenty than sixteen," he said. "Matt's is about normal for his age range. From what I can tell, she got a lot more of the drug than he did." "But she's OK?" "Fit as a fiddle," said Dr. Fisher. He looked a little nervous. "This is a little awkward, but during the interview she admitted she's sexually active, and she couldn't remember when her last period was. She says she's on the pill, but I took the liberty of doing a pregnancy test. I hope that's OK. It's good that I did, though. She's about four or five weeks pregnant. I won't know for sure until we get an ultrasound. The point is that it's going to be very interesting to see how this affects her pregnancy. That can be hard on teenagers, but her body is at a place right now that I think will make things much easier for her." "Pregnant." Bob's voice was dull. "Did you tell her?" asked Bob. "Of course," said the doctor. "She was a little resistant to the idea that her birth control pills didn't work, but I explained how that sometimes happens." "But they're both all right?" asked Bob. "They seem as normal as the day is long, physically. And they get along much better than most siblings I've seen. They were so happy to have been found normal that they were actually kissing each other when I came out here to give you the news." ------- The End ------- Posted: 2009-03-30 ------- http://storiesonline.net/ -------
