SPECIALTY DRINK

Whatever it was that Ron drank had effected him far worse than he thought, now that he was sweating and having a very hard time concentrating. He was yelling at himself for being so careless in the lab. If anything was left out on the table in plain sight, there was no way it would have been something dangerous or some type of drug, not in a cup, not in a glass, nothing that would scream "drink me". But whatever it was, he'd taken a big gulp of it, and now his insides were burning, his skin was beaded with sweat and there was a burning in his crotch like he'd never felt before. Sitting in his cubicle was starting to hurt, he wanted to go to the bathroom, but he wasn't sure he could make it. A coworker stopped in to say hello, peeking her head over the top of his cubicle wall. It was Sara, and she was beautiful. She had long brown hair, wonderfully large breasts and milky tanned skin. He had the hots for her, and she had been sort of interested in him for sure, she loved to flirt with him but now suddenly something was happening to him that was straining his mind to it's limits. Even as she spoke to him, wondering if he was ok, his heartbeat picked up it's pace and his cock began to swell inside his pants. It strained his underwear as it tightened into an erection quickly growing hard as a rock. Ron was thankful that he had his legs tucked under his desk as his dick strained the confines of his pants, pulling them tightly outwards from his crotch as his cock erected far further than he remembered it could.

He wanted to run for the bathroom before it was too late, but staring at Sara made him want her so bad, he couldn't take his eyes off of her. Every word that left her mouth made his cock swell larger and larger, straining the zipper of his trousers to their limits. He felt his cock ram into the underside of his desk now, straining into it so hard that his chair practically pushed downwards, and still it swelled and buldged. Ron gripped his crotch and quickly spun his chair and ran for the bathroom, apologinzing to Sara as he ran. Sara looked concerned and followed closely behind. Ron ran into the bathroom and locked the door behind him, thankful that it was a one person bathroom. No sooner had he heard the clack sound of the door lock engaging when his cock tore open his pants, popping the zipper wide open and erecting so hard and hotly into the air that his underwear tore apart in the front. Ron's eyes bugged out as he pushed up against the door, panting hard, taking heaving breaths as he watched his cock bouncing and swelling before his eyes as the veins on it's surface grew larger and thicker in seconds. His cock looked like a third arm it was so big now, almost three feet long and almost as thick as his wrist. It was pulsing madly, the muscles thickening and growing tighter each second as the veins pulsating on it's surface seemed to make the whole shaft almost red in color, and very hot to the touch. Ron couldn't believe what was happening, sure he'd always wanted a bigger cock, but this was almost impossible to believe. His attention came back to him as his cock shuddered and began to pulsate and bounce to his racing heart as it swelled even larger, causing him to gasp and moan as he took it into both of his hands, gripping it as if it were a water hose about to turn on full blast.

Ron knew what was coming, he was! In fact he saw precum dripping from the huge tip of his cock, already forming a puddle on the floor. Barely ten seconds passed before Ron felt pleasure like he'd never dreamed flow through his body causing his cock to swell quickly and finally release a flood of hot cum everywhere, shooting all over the wall across from the door and then down all over the floor. It wasn't like a couple of quick releases, it was literally flowing from his cock like a water fountain, and he came, and he came more, and came even more, more than any human should have been able to. It was like he poured six gallons of milk from a jug onto the floor. Ron heard knocks coming from the door, from outside, from Sara, asking him to respond to her, to tell her he was ok. He barely had enough strength to stand let alone make up a story, so he replied that he was just fine, only that he'd gotten sick and threw up all over the floor. He assured her he'd be just fine, and he'd need some time to clean up the mess. Little time was a gross understatement for sure. Ron used almost three rolls of toilet paper and half a roll of paper towels to clean his cum off the walls and floor, and time, well it took over an hour for him to get it as close to normal looking in the bathroom as he could. By then his cock had returned to it's normal flacid state, though it was still feeling somewhat warm for having just exploded like it did an hour ago. Finally stuffing the last of his cum soaked paper towels into the trash can, Ron made his way out of the bathroom and back to his cubicle, several concerned coworkers making sure he was ok along the way. He assured them he was fine, but his boss was waiting at his cubicle to send him home for the last hour and a half of the day, not one to take chances on an employee getting everybody else in the office as sick as he was. He was lucky to have such a nice boss, and thanked him as he picked up his stuff and made his way to the car.

Ron got home and felt so exhasted that he layed on the couch and fell asleep. He awoke several hours later to knocks on his door. It was Sara, come to check on him at home. He invited her in and in fact, wasted little time telling her the truth. She gasped and held his hand, telling him she'd find a way to help him. Sara worked in the laboratory, and she told Ron that what he'd drank was a new experimental impotence cure, only in a highly concentrated form, never meant for human consumption on the level that he had drank. Ron apologized for being so stupid and Sara gave him a hug, and something else. Ron felt her breasts, her big beautiful soft yet firm breasts pressing against him and almost in an instant he felt his cock harden quickly, shoving his pants outwards in seconds. He pushed her away but couldn't seem to let go of her arms as he threw his head back and moaned, his cock quickly bursting out of his pants, popping the button off and ripping open the zipper. Sara gasped as she saw this monster cock growing from Ron's crotch and pulled away while Ron gripped the couch and screamed, as his cock swelled larger and larger into the air, thick veins pulsating to the beat of his racing heart as they grew thick and turned his whole dick red. Sara gasped as she nearly fell backwards onto her ass at seeing how huge his cock had become in only a few seconds. Precum started to leak from the tip and Sara hesitently reached up and almost without thinking, licked some of it off, swallowed it and felt a wonderful tingle roll down her throat. Ron begged Sara for help before his cock exploded or to get out before he died and call for help. Sara wanted something else though, and she knew it wasn't help.

Sara felt her nipples expanding inside her shirt, growing harder than normal as her crotch became wet so quickly, she didn't even have time to take them off. Her skin began to bead with sweat as she felt something even stranger happening. Her chest began to tingle as her breasts began to expand, starting to stretch her shirt outwards further than the buttons wanted them to go. Sara gasped and moaned as she watched them expand, a gurgling sound filling the air as she felt their weight increase, realizing that she was producing milk at an exponential rate. Her nipples grew outwards nearly three inches and thickened into giant puffy nipples that turned deep purple and began to throb. Heat spread over Sara's entire body, and her crotch felt like she'd rubbed Ben Gay on it it was so hot. Suddenly the who and the why didn't matter, only one thing, Ron's cock. Sara looked down at Ron who was panting with heaving breaths as he stared in awe at what had just happened to Sara. His cock was standing upwards from his crotch over three feet, and Sara wasted no time at all in ripping apart her shirt and beginning to give it a boob job, and with purpose. Ron came almost instantly, spraying Sara's face with his hot cum, to which she simply drank as much as she could and licked the rest off her face as best she could, before returning to her expert blow job. She was good at it, so good that Ron came over and over, draining his stamina but definitely not his raging hard on over the course of the next two hours. Sara couldn't believe he'd not only stayed hard for this long, but still had cum in him. It was time for Sara to get serious now, as the cum she had drank had caused her breasts to swell into the G range of sizes and her pussy was practically cumming by itself from how much heat and throbbing her clit was doing down there. Sara leaned over the edge of the couch and stuck her ass into Ron's face, daring him to give it to her. She need not have made such a dare since Ron was still so horny he would have fucked a refridgerator at this point, and wasted no time at all ramming Sara's pussy to the hilt with his gigantic cock. Her pussy was hot, slick and tight, all the things he could have dreamed of, and felt even more wonderful than her tits and mouth ever did. Sara was screaming in bliss and almost crying from pleasure, cursing herself inside her mind that she hadn't done this sooner. She'd had the hots for Ron for months and had almost asked him out several times, but she'd always been a little unsure of herself. Well not now that his dick was inside her so far her stomach felt full, but before today she'd never have thought he'd be fucking the hell out of her, and not with such a huge dick like this.

It felt like eternity that Ron had been ramming Sara's hot cunt in every way he could think of, but in fact, it was only about an hour. Even so, both of them had a new found stamina that could rarely be seen in men or women making love, or love fighting depending on who you asked at the moment. Pieces of furniture had moved a bit while Ron sent Sara over the edge of maddening orgasms several times since they began, and she too, had felt Ron's hot cum spraying her insides several times, but finally it actually seemed like a final orgasm had drained both of their bodies enough of the heart racing, drug induced, super Viagra loving, monster cock fuck session, that after one final deep push and spray inside her, Ron felt his cock's strain lessen, his heart began to slow and he finally caught some breath. Sara was leaned over the couch, her legs were sore, as was her pussy, but even as she felt Ron's cock going flacid as it pulled from inside her, she knew she'd do it all over again without regrets. Another few minutes passed as Ron sat down onto one of the chairs, letting Sara free of his monster cock's grip for the first time in almost two hours, and tried to keep himself from begging for forgiveness or praying for redemption or something to ease his mind. Sara weakly told Ron she had dreamed of all this for a while now, and expressed her true feelings for him, telling him how much she loved him and how much she thought of him, especially that he would even share himself like this to her. Though Ron was happy with the turn of events, he was also worried that it may have just been the drug he took that made her say such things, and he told Sara these things. She was unphased however, as she mentioned that while the drug did change the libido of the person, it didn't change the feelings they had for other people, thus, loving her and her loving him was already a natural idea, and his larger cock and fuck session was not a result of the drug, but a result of love. If anything she told Ron, it merely enhanced their connection, making it so strong that what he just did was like a walk in the park, unlike any normal man who could barely hope to get hard more than three times in an hour, let alone stay hard for over two jackhammering his way into her honey park. Ron seemed a lot more relaxed and releaved now and told Sara they should take a shower and clean up, together. Sara could hardly protest but even as they got into the shower and let the hot water wash away the dried cum and sweat, Ron couldn't stop his heartbeat from picking up again, just touching Sara from behind, holding and kneading her new larger, firmer and softer breasts. Sara couldn't resist either as she felt his cock sliding up against her ass cheeks as it began to erect once more, growing hotter, larger and thicker as it went. In seconds her nipples were three inches long and hard as steel, drops of milk leaking from their throbbing tips as she watched Ron's cock slide between her legs and outwards, past her crotch, swelling into the size of a human arm quickly. The huge veins pulsated on it's surface once again, and the heat coming from it was like a stove's burner, making her pussy so wet it felt like rain running down her legs instead of the hot water.

Sara leaned her head back and told Ron to do it, to take her, to shove his thick cock up inside her wet pussy. Ron, panting and with his cock throbbing hard, seeking aid, he did as she asked, sliding Sara over to hold onto the wall while his huge cock slid past her outter folds, shoving them aside like a missle through a concrete bunker wall, all the way to the hilt, making her scream outloud with pleasure once again. By the time the hot water had turned to almost cold, they had found a way, somehow, to cum at least ten or eleven more times each, draining their stamina to the point of passing out. Ron took his time in getting his cock out of Sara's pussy, and then slowly got out and dried himself off, offering Sara her own towel so she too, could get things nice and dry. But just watching her dry off already made Ron horny again, and in amazement and fear he watched his cock swelling before his eyes into another hard erection that pulsated and throbbed as it began to lengthen and thicken again into something more than a penis but a little less than a third arm. Sara's eyes widened when she finally looked up and saw Ron's cock growing into it's monsterous form once again. Now despite her mind screaming at her to suck that huge ass cock, fear was starting to override her lust. She feared what would happen to her if she kept getting fucked by something so huge, not to mention what might happen to Ron if he kept going and going without any rest. He could die of a stroke or pass out and go into a coma, even if he had his huge cock buried in her soaking cunt. Sara already began to find things getting hazy, and finally caught on that her own horniness was most likely a pheromone side effect of his massive injestion of the formula. He was omitting something so potent that any female too close was sucked into a cock licking, sucking and fucking vortex, unable to control their own sexual urges until Ron satisfied them with a nice huge veiny cock rammed inside their pussies. Even thinking in the way she was, Sara knew she had to do something, and she wasn't sure what. Ron was pleading with her that she should leave and leave him there while she went to get help, but she told him that there wasn't much to go get help for since the drink he drank was a prototype, there was no cure, vaccine or antidote for it. Ron's heart was racing but it found enough time to sink into a slight depression at the news that he was doomed to die at the hands of his own libido. Sara giggled and assured him that wasn't going to be the case, as the few test subjects they had used, mostly mice, rats, cats and dogs, though overly horny and in need of mating once injected, didn't stay that way once they had gotten the serum out of their system. The problem wasn't if Ron would return to normal, it was after how long. Since Ron only knew about what he'd drank, Sara had no way to accurately tell him when the serum would work it's way fully from his bloodstream and return him to normal. It could be days, or maybe even a week or more. Ron again begged Sara to help him however she thought best, to which she knew of only one way right now.

Sara turned her pussy toward Ron's aching dick, leaning over onto the bathroom door. Ron protested as best as he could, and Sara told him it was ok, since at best it'd help work the serum out faster, and at worst they'd both die of unholy pleasures unknown to man or woman. Ron managed a grin as he once again penetrated Sara's hot cunt to the hilt with his Spear of Longinus, driving her to cum almost instantly and making him feel the lust of a thousand men. Ron was a lucky bastard right now and he knew it, but he also knew that this was only temporary, or at least he prayed it was. Sara was smart, but she didn't know everything about what he'd drank, and what if she was wrong? What if his condition never got better, or got worse? Ron hoped his fears would go away as he fucked the woman he loved, but it lingered, and he didn't like things to linger. Sara's knees eventually gave out as she slid down the door and onto the floor, and Ron did his best to keep her up using his huge dick, mostly sucessful because of it's size and muscularity. Another good half an hour passed before Ron felt enough cum leave his dick to spraypaint a house, letting it shrink from within Sara's pussy and return to a flacid state. He jumped into the shower and took as cold a one as he could, shivering half to death before he got out. Amazingly the cold water felt good and seemed to clear his mind a bit. He almost ignored Sara completely, not even looking down at her, but she watched him in silence and understood what he was doing, and didn't hinder him at it. After he walked out of the bathroom, towel in hand, she slowly got off the floor and took a cold shower as well. She finished and got cleaned up and waited around for a while in the bathroom, hoping that Ron had been able to calm himself down enough to go to sleep, or at least to have been exhasted enough to fall asleep. Sara carefully opened the door and peaked outside. His bedroom door was shut and she could practically hear the snoring from across the room, which helped ease her own mind. She dared only step out of the bathroom far enough to pick up the wet towel she saw on the floor about halfway to the bedroom, before she returned to the bathroom. She knew that it was possible that her own scent may have been what had been driving Ron's libido out of control, so her best bet was to stay far from him for a while. In fact, her own senses seemed to be clearing up now that Ron wasn't near her, and she sighed with relief that maybe things would be better in the morning.

Ron was snoring and passed out in his bed, only covered by a light sheet, but that didn't stop his cock from doing anything. Already it was slowly erecting, buldging and lengthening. It pulled him to his side and grew outwards along the top of the mattress, making the sheets look as though they were covering a python. And still, lost in exhastion, Ron didn't wake up, though he began to moan as his cock still grew outwards, hardening further and growing in girth, reaching the edge of his bed, the veins pulsating on the surface, making it look like some alien arm. Precum was starting to release from it's swollen tip, wetting the sheet and mattress quickly, and still, lost in his wet dream, Ron's cock continued to swell larger and longer. Past the mattress it grew, sliding down toward the floor, too big to pull itself outwards in a straight poll like position, but as Ron continued his dreaming, the muscles of his cock grew larger, increasing it's girth by almost four times, pulling it straighter and tighter. It began to lift from the floor, hardening into a state that no earthly man should ever see skin or muscle harden, but on it hardened, tightening and throbbing until every last vein stood pulsating on it's shiny surface like the three dimentional representation of mountains on a road map. It stood almost six feet outwards from Ron's crotch, easily leaking more precum in a minute than most other human males could leak in a lifetime, and though still sleeping, his breathing was fast and ragged and he was sweating so much he may as well have just gotten out of a swimming pool. Again Ron moaned, his subconsious desire to fuck was beginning to push his body to the limits of human sexual appetite. Soon, Ron began to cum, each blast coating the wall across from the bed, more leaking out as it began to trickle from his giant, grapefruit sized head in a near steady stream. And all through it, Ron was sleeping, enjoying a dream he thought was real, so real he didn't want it to end. His body began to churn, his muscles creaked and his cock throbbed harder and harder, craving a pussy, needing it, almost wanting it so bad as to detach from Ron's crotch and seek it on it's own.

Sara was already half asleep in the bathroom, laying in the tub when she felt a tingle rolling through her sinuses, a delicious tingle, one that woke her from her dozing and into a quick state of arousal. Her nipples hardened almost instantly at the smell, and her clit immediately began to swell from inside her dampening folds. Her heart began to beat faster and drops of sweat slid down her face. Alarmed slightly Sara carefully got out of the tub and looked in the mirror, calmly trying to figure out what was happening now. She knew Ron was sleeping, as she could still barely hear his snores coming from across the room, coming from the bedroom there, so right now there should be enough distance between them that any pheromonal activity should be well disappaited before ever coming close to her being able to smell it, let alone get her aroused from it. But the gurgling sound that began to come from Sara's swelling breasts was no normal pheromonal activity, it had to be coming from Ron, as it had done this to her before, when they first became aquainted. Sara tried to think about what might be causing this sudden bit of growth, but the more breaths she took in, the sweeter the smell became, and the hornier she got, and the more her body began to crave something, to crave cock. She tried hard not to focus on Ron, and went to the small window and opened it, hoping some of the cool night air would calm her down. And it did, for a few minutes, but the smell was getting stronger, almost overpowering all her other senses, and Sara was starting to panic as she went back and looked in the mirror. Her hair was starting to grow longer, down into her face, and past her shoulders, and her breasts were filling with milk faster than ever, swelling to D, then DD, then E, and beyond as her nipples swelled large and purple atop puffy aerola that were growing in diameter with each sweet smelling breath she took into her lungs. Her pussy was tingling with such a hot sensation she couldn't keep her fingers off of it, and in it, and even as she played with herself, she saw her clean shaven bush starting to sprout much longer and thicker hairs, twisting and twirling out of her pours as it grew into a rich thick tuff of beautiful brown hair. Barely able to stay focused on anything else, Sara saw her hair had grown down her back and across her ass cheeks, moving further down to her knees before stopping and thickening into a head of hair any indian may have killed for back on the wide open plains of the American west.

Sara was beyond fear now, her body was dripping with sweat, and her fingers, all of them, were not helping the burning heat that was pouring from her vagina. She knew there was only one way to stop this, and as much as she wanted to stay away from Ron, to stop him from dying if things went too far, she had lost the fight with logic and her body began to move on it's own. She wanted cock, she needed it inside her, she had no choice. She barely turned away from the mirror when she came hard, spraying her legs with her juices and causing her breasts to swell even larger, the skin pulling tight across them, her beautiful silky skin showing her pulsating veins just under the surface, as more milk flowed into them. Her nipples grew larger, longer and thicker, milk starting to dribble constantly from their engorged tips, flowing down her torso and mixing with her pussy juices. She could smell herself, the sweet smell she was giving off, almost as sweet as the air coming from the bedroom, and from Ron. Sara began to drool, barely able to walk she was so wet and horny, she finally made her way from the bathroom, across the living room and opened the door to the bedroom. She gasped as a bit of logic mixed with fear lept into her weakened mind as she saw his cock, or rather, the last couple feet of his cock, sticking out from under the bedsheet he had just barely tossed over himself when he passed out. The sheets were hovering off the bed a good foot while his dick had made a nice little hole from one edge of the bed to the other larger enough to let a child crawl under it. She saw how large it was, thick, hard and oozing cum from the tip, it was swollen, red, rough and hot to the touch. The veins pulsating on the surface made it look far from human, but the shape, the wonderful shape Sara thought, would go into her so great. She didn't even try to think any of the other sexual thoughts away as she bent herself over and slowly backed her soaked cunt into his hot throbbing cock. Inch by inch she slowly slid Ron into her, all the while listening to him moan and snore. She couldn't believe he was still sleeping through what she was doing, and thought maybe it was another side effect of the serum, but all thought began to fade from her mind as she reached her cervix with a thud and a low moan escaping her parted lips. Ron's cock was so hot it was like she was sliding a hot hair iron into her pussy, but it was also pulsating to his heart, soft, yet hard and the veins made it feel incredible as she began to work herself in and out. She was doing all the work this time, but it hardly mattered, in fact nothing else did but the bliss Ron was giving her, even if she was the one making it happen. Her pussy squeezed down hard on his shaft so badly that it was as if her pussy had been starving and this was it's first real meal in months. It drove her mad with lust and pleasure and as she pumped Ron's cock in and out as hard as she dared she felt him cumming over and over, harder and harder each time, and though she loved the feeling, Sara just hoped that it was somehow helping to work the last of the serum from Ron's body, hoping he'd return to normal before one of them was literally fucked to death.

It was almost an hour before Sara became too worn out to move any further and with a last earth shattering orgasm, she finally slid Ron's monsterous cock from inside her vagina, watching gallons of cum spray from inside it, and almost fell flat on her face, out of breath and out of strength. Barely able to move, she was able to turn over and watch Ron's cock return to a little more normal size and shape, though it was still large and hard as she could see it's basic shape holding the sheet upwards above his crotch. Thankfully though, Ron's breathing and panting had slowed enough that he was now sleeping much more soundly, something Sara badly needed now as she made her way out to the living room and fell onto the couch. Her pussy was aching and so were her legs, but she had to sleep, her body was too drained for anything more tonight. Sara passed out like a light pretty fast, and began to dream. But this dream wasn't normal, even as worn out as she was, the serum continued to work on her mind, much like it had on Ron. Despite not actually drinking any of the stuff, she had drank Ron's hot cum, and had gallons of it shot up inside her, and though she hadn't even thought about it, that cum was laced with small traces of the serum. Not enough to do much in small doses, but with the amount she had absorbed, even more so that some of it had been on her vagina, absorbing much faster than through her stomach or outter skin, was causing very interesting changes to course through her body. The serum was never meant to be given to women, it was designed to be a cure for impotence in men, but now that it was in a woman, in very concentrated doses, side effects were starting to manifest while Sara was passed out on the couch.

Her breasts were swelling once again, firming up and growing larger while her nipples hardened into rocklike points as they too, began to swell and grow outwards, several inches longer than normal. Her aerola began to increase in diameter and turn darker, puffing up and becoming very sensitive. Her breasts continued to swell and buldge, but not just that, the muscles in her chest also began to expand, growing tight and toned, pushing her breasts higher into the air and making them even more firm and beautiful. Sara began to moan and squirm as more changes swept down her body. Even as her breasts continued to swell outwards, leaking milk from her giant purple nipples, her mind raced with lusty images of huge cocks and being fucked by them, Ron's was in there, and a few other people her mind was making up, but there were animals, horses, dogs, all kinds of things with huge cocks, filtering through her brain cells. Each thought that she tried to focus on made her pant, and made her pussy contract, even as it began to change. The outter folds puffed up and began to grow muscular, firming up and becoming nice and ready for a cock. Inside, her muscles also firmed and bulked up, become much stronger, much tighter and a lot hotter to the touch than ever before. Her clit too, began to swell outwards from her folds, swelling up and turning a deep pink color as it grew as large as a thumb and began to throb with her heartbeat. Sara was sweating badly, much like Ron had been as her brain cells turned to mush as she dreamt such horrible wet dreams it wouldn't have been a surprise if she began floating off the couch and down a river just from the sheer power of the serum on her mind. And work on it the serum did, but differently than it had on Ron. While Ron's body had been craving pussy, releasing pheromones to draw Sara in for a fuck, Sara's body wanted to go far beyond drawing in a man. Sara's body wanted to make her a beast of sexual desire, a predator of cock that could hunt it down and take it whenever, or wherever it pleased. And Sara couldn't resist such a desire as she pictured herself taking Ron, and other men, in ways that made them howl with pleasure and scream with desire. She bit her lip and moaned as the serum's power began to change her body to the will of her sex craved mind as her body began to twitch and pulsate as changes swept over her entire body from head to toe.

Her hair began to grow longer than ever, but not just from her head this time, as small brown hairs began to curl upwards from every pore of her skin, slowly at first, but then much faster as it began to grow longer and thicker, quickly covering her shoulders and arms and then moving downwards to cover her chest in a rich, thick pelt of fur. Her already thick brown bush began to twist and twirl upwards, coating her hips and stomach in fur, meeting up with the hair coming down from her chest before it spread to her inner thighs and down around her soaking pussy and began to cover her legs in the same rich fur that now covered the rest of her body. The hairs glistened in the dim light of the room as Sara's body was sweating badly from the heat of the transformation pulsing through her body. The hairs stopped at the tops of both of her feet before thickening on top of itself until Sara's entire body was covered in thick, brown and soft fur. And all the while, she slept and moaned, panting hard even as more changes swept over her body. Sara's fingernails and toenails began to split apart as long black claws pushed their way outwards, curving and sharpening into claws in seconds. Sara growled a little as her mouth opened and her teeth grew quickly into sharp points and even her tongue shifted and grew longer and rougher than normal. She began to toss her head as the hair on the side of her head moved as her ears poked their way outwards from behind the hair curtain and quickly grew long and pointed before a soft and short pelt of fur covered them all the way to the tips. Sara moaned outloud as her chest seemed to heave upwards suddenly as her breasts, already giant EE cups, swelled further than ever, more muscles ripping under her skin as they swelled another two cup sizes in seconds. More hair grew over them quickly even as they swelled and even more changes flowed over Sara as she moaned and her nipples grew larger and longer, turning a deep red color as they grew outwards, past her furry chest and at least four inches long and hard, standing erect and leaking drops of hot milk. Soon after, more moans from Sara brought more changes as her furry stomach pulsated as two more sets of long, red, hard nipples poked their way through the thick furry pelt there, growing the same four inch size as the ones that topped her massive breasts. Shortly after however, they were on the move as her skin began to pulsate and shift, pushing those nipples outwards as two extra sets of breasts began to form under her main two. They swelled to just under a cup size smaller than her main breasts, but they too began to leak milk as they firmed into perfection. Sara almost howled as the final changes swept over her as ever muscle in her body clenched at once and began to expand, flooding her body with power as they began to expand and grow. From head to toe, Sara became as big as a body building champion in seconds. Even her pussy firmed up both inside and outside, far further than any human's could. With a final snarl and a whimper, Sara came hard, harder than a man even, as she sprayed the couch with her juices and fell off the couch and onto the floor with a thud that woke her immediately from her slumber. Her eyes had changed from their normal green to almost a yellow amber as they began to dart around the room, almost in a paniced state.

Sara's mind was having trouble coming back to full swing, she found it almost impossible to think straight as she slowly stood up and looked herself over, gasping in a half growl. She was a large furry person now, that much was more than obvious, like a werewolf that was in dire need of a mate. Sara could feel her mind losing control and even though she was scared nearly to a state of panic, she was also horny on a scale that could not be measured. Her juices were in a constant state of leaving her vagina to cover any surface she was standing over and her nipple's were about to go balistic on her if somebody didn't start suckling on them soon. Soon Sara felt that delicious tingle roll through her body, that sweet smell that was now far more amplified, most likely like the rest of her senses. Her sight was better, her hearing was far better as she could hear Ron's heartbeat in the other room, and her libido, was almost a runaway train wreak. Sara reached her clawed fingers down to merely think of touching her hardened clit and the feeling of her thick fur brushing against it first knocked her off her feet as she sprayed her hot cum all over the floor behind her as she hit the floor on her hands and knees. She began to pant and unbelievably, her breasts began to feel tight as they once again expanded, her nipples growing another inch in length and thickening into almost a two finger's width diameter. Sara's mind could not resist this type of assualt any longer, she had to fuck, and be fucked before she died of pleasure or a heart attack. Any other logic beyond that one thought was meaningless as Sara practically crawled toward Ron's bedroom, each movement making her breasts spray milk and her pussy spray hot girl juices, which in turn made her breasts, all six of them, expand more and every fiber of muscle in her body expand larger, thickening her into a body that could break battleships if they ran into her head on. She began to drool as she made it to the bedroom door and opened it quickly and easily saw Ron sleeping on the bed, where she'd left him hours ago before she passed out on the couch. His cock was still erect and throbbing, holding the sheet upwards from his crotch at least a foot or more. Sara was running on pure instinct now, growling and snarling as she made her way up and onto the bed, quickly removing the sheet from his throbbing cock.

Her eyes widened as she took the massive thing into her mouth and began to suck and fondle it, it's skin hot to the touch. It felt good in her throat, it tasted good on her tongue and Ron, beginning to pant started to actually wake up. What he saw, though through very groggy eyes, was enough to make him yelp outloud in fear. Sara slipped her mouth off his cock long enough to glare at him, a look of need in her eyes. Ron recognized the face and he tried to ask Sara what had happened, what in God's name had he done to her, but she growled when she opened her mouth, as if she could no longer talk. Ron watched her move to the side of the bed, getting onto her hands and knees, pointing her fur covered ass toward him, begging Ron to fuck her. Ron was hesitant now, as he thought if he had done this much to her from fucking her earlier that night, what might happen if he did so again? Sara rammed her ass into his crotch and Ron yellped slightly from it and decided, that if they had to die, at least they'd die together in a loving way.

Ron finally noticed just how swollen, hard and huge his cock had become and he gasped, but it was so hot and throbbing that he could do nothing more but put it where it was best served. Sara's claws dug into the bedsheets, tearing them apart as Ron's cock spread her pussy apart like a missle through a brick wall, and he penetrated her to the hilt. Her hot cunt grabbed it like a starving child would grab a sandwitch, it felt to Ron as if his cock was being pulled into her rather than him pushing in and out of her. Her pussy was far stronger than he remembered, it was gripping him so tightly that he felt almost every small fold of her vagina as it rubbed across his new hot, veiny dick. Ron was beyond words, as only low moans could make it out of his mouth, and Sara was growling and practically whimpering like a dog, or maybe a wolf as she certainly looked like a beast now. And still, Ron still loved her, and her soft furry ass somehow felt even better than when she was completely normal. It was soft and warm, and just, somehow, made everything feel that much better to him. Ron yelped slightly as Sara's pussy suddenly spasmed and exploded with hot cum, spraying the bed and Ron's legs, but he didn't even care as it only made his cock swell even larger inside her, tightening harder and growing in girth, spreading Sara's hot cunt open wider and wider. And he felt her pussy sucking it all in, every last, hot throbbing inch disappeared into her and she moaned and growled and whimpered in pleasure like she'd never felt before in her life. Sara's mind was lost in a hot fog, she was in heaven and hell at the same time, unable to think clearly beyond the hot cock in her pussy, and in her heart, she knew she wouldn't have it any other way right at that moment. She, for the first time in her life, finally felt that her life couldn't get any better, she had found the man of her dreams, and had shared everything with him, and gone through the craziest experience anybody could with the one they loved. After things returned to normal, Sara knew she was going to get rid of that forumla from work and perfect it on her own time and maybe even improve on it, but she didn't want something this potent and incredible to ever make it outside the lab, unless it was her or Ron.

A quick thrust shot some of Sara's attention back into the current situation, and in fact the longer Ron pounded his thick cock into her pussy, the less cloudy her mind became, she started to moan more and growl less and she became more aware of her bodily changes. Though she realized she was now some hairy beast, she actually felt good about it, she felt powerful, horny as all get out, but powerful and sexy! She growled slightly as Ron suddenly grabbed her and turned her to her side, lifted one of her legs up and began to fuck her hard from a different direction. Sara looked up at him and smiled and he returned the smile as he moaned right along with her. Ron couldn't believe what had happened to him and to Sara, just from one big gulp of strange tasting liquid from work, a massive impotence cure that seemed to do more than cure a man's disease, far more. But Ron's mind quickly moved back to more pressing matters, or rather, squeezing matters as he felt his cock growing larger still, pushing Sara's legs further apart as well as making her pussy that much tighter as it gripped down on his cock, sending shock waves of pleasure all the way up and down his spine. Sara's sexy, fuzzy legs rubbing on Ron's chest and hips made him feel incredible, as if she was protecting him in a weird way, it made him feel safe and loved. Ron thought how odd it was that he was thinking in a way altogether different than he had just even a day ago. He smiled as he spun Sara back to her stomach and leaned her back up against his chest, gripping her breasts, shocked at first at the two extra sets he had somehow missed, but began to squeeze and twist the elongated and swollen nipples poking up through the soft pelt of fur that covered them. Sara moaned and milk began to spray from the engorged tips of her hot nipples, soaking the other side of the bed with it, but Ron simple nibbled lightly on one of Sara's fuzzy ears and whispered how much he loved her as he did. Sara grunted and growled a love you too reply, whether Ron could understand her new beastial language she wasn't sure. What Sara was sure of is that Ron's cock was growing larger rapidly, growing hotter rapidly, about to release a flood of hot cum deep within her vaginal wallls. Ron began to grunt loudly as he neared his climax, and Sara could practically hear the cum moving through his cock as it began to tremble and shudder. Her vagainal muscles clenched down hard on his cock as he exploded inside her, jets literally spraying for several long minutes, filling her to her limits, most of it pouring out between her soaking folds and his hard dick.

Several long minutes passed before Ron felt the girth of his cock returning to a more normal state, as it began to go limp for the first time since he'd drank Sara's super formula. He slowly pulled out of Sara's vagina, even as it gripped down on it, as if his cock was a long lost friend and her pussy didn't want him to leave. But Ron fell back onto the wet bed, panting, and pretty much out of stamina. Sara, though feeling somewhat satisfied now, was still not returning to normal, at least, not enough back to normal. Her mind was clear again and she could rationalize what had happened, but her body was still on the edge of hotness, her body was still furry and her muscles were still large and tight. Ron made a smiling comment about Sara now had no chance to be the man in the relationship as she was now not only hairier, but much stronger now than he was. Sara rolled over beside Ron, snuggling up to him as he put his arm around her, rubbing her fur, making her moan a little. Sara tried to speak again saying how they'd work it out and how glad she was that he had stuck through this whole experience with her, but as before, the grunts and growls she put out were hard to understand, even for her. Ron did understand though, and for the first time in almost two days, he finally felt sleepy. Sara too was starting to doze a little as she listened to Ron's heartbeat slowing, his breathing becoming more normal, his eyes closing as he started to dream. Sara watched and gave him a quick lick on the cheek and began to close her eyes, hoping that at last she could rest, with the man she loved.

Sara awoke sometime in the morning, hot and sweating badly. Ron wasn't in the bed with her, but she could smell something odd in the air and it took her a few seconds to figure out that it was food. Ron was cooking breakfast, but the first thing on her mind was finding out what was wrong with her. Sara hopped out of bed and walked over to the mirror hanging on the wall. She was back to normal, well mostly. No fur, no fangs, no extra breasts, no claws. Her hair was longer than normal, hanging down to about the middle of her back, but it looked wonderfully full and vibrant. Her breasts were larger than normal too, and even firmer than she had ever known, as well as a lot more sensitive to the touch. Her entire body was now toned with muscles, not body builder size, but a nice looking workout oriented body for sure, much stronger than she had been two days ago. Her senses seemed to be much better as well, not as super human as they were the night before, but her ears could hear the sizzling of something on a hot pan in the kitchen, and Ron was humming her favorite song. She could actually smell the meal he was making now, eggs, bacon and toast, and it wasn't even burnt. The only problem now was that Sara was sweating and her heart was beating faster than normal, and she could swear something was still wrong with her. She felt anxious and a bit horny. Hoping she just needed to go to the bathroom Sara went to the bathroom and closed the door. She didn't even make it to the toilet before Sara was hit with a massive wave of hotness that swept through her entire body like a mega blowdryer hitting her from all sides at once. She leaned onto the counter as her heartbeat picked up and she started to sweat even more, drops sliding down her cheeks and chest.

Sara became concerned as each second she felt her body starting to twitch and shake, and she wasn't sure what was going to happen. Her heart began to beat faster and harder and she moaned as she felt her nipples harden quickly, growing thick, long and purple. Her aerola puffed up and began to expand in diameter and Sara knew instantly that her breasts were starting to expand. Sara gasped as she watched her breasts growing larger right before her eyes, and fear crept into her mind as to why she was changing again, and this time into what? Then she remembered that it was Ron's cum that had made her change before, and it had taken most of the night to actually kick her body into that mode. What she forgot was that well into the morning she had been letting Ron fuck her, and cum inside her. Oh no she thought, it was his cum, his serum laced and concentrated cum, only last night she wasn't herself, she was transformed into something else, something more sensitive to the effects of the serum. And now, it was hitting her hard and fast, her body was changing again, faster than she could react to it, and she knew she couldn't stop it from happening. She thought about calling to Ron for help, but she wasn't sure if he wouldn't be forced into fucking her again, keeping the loop going on and on, until the serum worked it's way out of his cum, if it hadn't already made a permanent change inside him, inside his DNA that would never allow him to return to a completely normal state.

Sara blinked as her hair began to grow down into her face, continuing to lengthen and thicken even moreso than it already had, flowing the rest of the way down her back to her ass cheeks, then past that to her knees. Sara's body was shaking and she held up her hands and watched as her nails began to grow longer, but unlike last night, they weren't spliting and becoming claws, just growing longer and far stronger than the nails of a normal woman's ever grew. Still they grew longer than she'd ever seen them, easily two maybe even three inches in length before they stopped growing. Sara saw her hand pulsating and turned it over with a gasp escaping under her pants. The veins running down her arm were growing larger, puffing up and pulsating to her beating heart, swelling on the top of her skin. To her amazement she felt her skin pulling tighter as the small amount of body fat in her body seemed to be melting away, pulling her skin taut and firm, the veins on her arms, legs and chest began to show from under her tanned skin almost like those on a body building superstar. But her veins were not the only thing growing and changing as only seconds later Sara felt a rush of energy entering her muscles the likes of which she could not describe. Her entire body shuddered and twitched as her muscles flexed all at once and suddenly began to grow. Her veins grew even more pronounced as her arms began to expand, her biceps buldged along with her triceps and shoulders. Her neck gained mass as her tendons snapped and grew larger and she could feel her back muscles growing larger underneath her tightening skin. The muscles in her chest began to expand, shoving her breasts outwards several inches as the veins in her breasts began to show larger and thicker under her skin. Her nipples began to thicken further than ever as veins crept up into them, making them expand outwards until they were as big around as a person's finger. They turned deep purple and Sara moaned through her clenched teeth as they began to pulse and throb hottly. Ripples passed through Sara's skin as inch by inch the burning swept down her body, pulling her skin taut and showing her growing veins upon their surface as her muscles buldged and swelled larger and harder, muscles Sara didn't even know a human body possessed. Her stomach clenched and Sara watched her abs turn rock hard and a beautiful six pack formed as her ribs began to show and were encased in muscle. Sara was starting to enjoy her transformation as she watched her legs pulsate and begin to grow as her hips and thighs gained pounds on muscle in seconds. Even her ass began to harden into two wonderful orbs of tightness the likes of which she never dreamed she'd see. Her hands went to her ass as even rubbing her smooth taut skin made her nipples stiffen even more as pleasure flowed from her ass to her hands and right through ever part of her body. Sara gasped as she snapped to attention when she felt her calves expanding and hardening, even as her tendons grew larger and more powerful in her ankles and feet. Even her toenails began to grow longer and stronger much like her fingernails had. But the changes were not over as the heat flowed upwards and right into her breasts and crotch.

Sara couldn't believe it but her breasts were swelling even larger than ever, pushing her flesh outwards and upwards as they buldged and grew. Her nipples grew even larger and her aerola were now giant dark circles on top of breasts nearing watermelon size. Pressure was building behind her purple nipples and as Sara gasped and took heaving breasts she felt something hot flowing into her breasts, filling them and making them heavier and even larger. She could only assume she was producing milk much like the other day, only at a much faster rate. It took only seconds before drops of hot liquid began to drip from her engored nipples, confirming her suspecions. Sara was getting hornier and hornier as her breasts swelled past watermellon size and into beach ball territory, and unable to resist she took one of her own giant nipples into her mouth and began to suckle. She nearly came from the shock of bliss that rolled through her like a freight train. Her hot mouth on her swollen nipple felt like the greatest cock in the world fucking her. As she suckled it almost felt like she was getting a hot dick shoved into her pussy and she only moaned and sucked harder, milk spraying into her mouth that was hot and sweet and delicious. The more she suckled, the more milk that sprayed into her mouth and the more that she drank, the hornier she got, and the hornier she got, the bigger her breasts and nipples became, making them swell even larger than should have been possible. But her newfound strength from her new buldging muscles supported the increased breast flesh with no qualms at all, it wasn't even enough weight to pull her forward. Sara switched to her other nipple, suckling onto it like a giant baby bottle full of deliciousness. Her mind was whirling with lusty, sexual thoughts, and she could not, dare I say it, would not just ignore them as she gulped down more and more of her own tit milk. Her pussy was burning with heat and her clit was throbbing hard into her outter folds as it stood nearly an inch from inside her, but that was changing, Sara could feel it. Pressure was building in her pussy, all the way up inside her vaginal hallways of lust, and it was increasing, building more and more, pushing something from within, something hot and hard, and growing. Sara wanted to look down but her milk, her delicious milk, she dared not let any slip from her hungry mouth to do so.

But the curiosity and the burning heat and pressure ended up getting the better of Sara's judgement as she reluctently let her breasts go from her mouth and looked down past them, barely able to see her feet until she leaned back a little and stuck her hips outwards while she leaned up against the bathroom counter. Her hips began to sway in and out and Sara bit her lip as pleasure from inside her built up and up and still up. Her heart was racing and the veins pulsated across every inch of her new muscular, taut, tanned body. She felt powerful and so horny she could fuck a football team, and she knew she wanted to so badly, she wanted cock, huge cocks. Wanted? No, she yearned for it, she needed it, like a cocaine dealer needed money. Her hips thrust upwards as her pussy let loose with a gust of hot cum as the pressure inside her vagina continued to build and push. Sara gripped onto the sink hard, nearly breaking the wood with her new powerful hands as the heat pushing from inside her began to part her outter folds like a flower blooming in the Spring. Looking down, Sara gasped and then moaned as she saw what looked like the head of a penis poking from inside her. She blinked and moaned as she watched the little head begin to push further out into the open air, buldging, swelling, pulsating and throbbing to the drum of her racing heart each second that passed. Sara's eyes widened as she watched it grow further from her crotch as thickening veins began to work their way up the hardening shaft, making it hotter and hotter, harder and thicker by the second. Her pussy still burned as it pushed from inside her and her pussy dripped with hotness and cum, so much it was soaking Ron's bathroom rug clear through. Sara could barely believe what was even happening to her as she slowly reached up and grabbed her buldging dick with her hand, nearly fainting as precum shot from the tip, continuing to grow as it slid upwards through her hand. She couldn't get her hand all the way around the thing now, and the head was almost reaching up to her neck, as big as a grapefruit and throbbingly hot. Sara's mind was losing whatever battle she could have been having about this strange transformation and it didn't take but a few seconds for her to grab her new cock, shove it between her giant swollen breasts and begin to give herself a boob job while licking the swelling head.

Her mind was racing in ten directions at once as she performed a blowjob on herself. It felt like heaven had been unleashed inside her and everything she touched in any way was making her cum and feel like nothing else would ever matter in the world again. Her tongue felt so wonderful on her hot, throbbing, veiny dick as she licked it with her tongue and drug her teeth up along the shaft as she came up for air. Smashing her cock between her giant breasts was such an alien feeling, she couldn't even come to terms on how to describe it, except to say that she now understood why men went crazy over having their cock's between a woman's big breasts. The shaft was growing thicker even as she sucked and licked on it, and even more heat rushed into it as the muscles all along the length tightened and grew harder, stiffer. The whole shaft was getting so hot it was starting to feel too hot to keep her breasts on the thing, but as it began to tremble in her hands and between her breasts, she realized very quickly that she was about to experience her first mother of an ejaculation. The head began to almost choke her and so she pulled off of her cock and watched the head swell even larger, almost as big as a large grapefruit as the tip turned deep red and hot precum began to drizzle from the tip. Sara wasted no time licking and sucking it from the shaft before swallowing as much as she could. It tasted wonderful, unlike a normal man's precum which was usually flat, sour or salty, Sara's was hot and sweet, almost tasting like honey in a strange way. She chalked that up to the effects of the serum changing the consistency of her cum into something else, something more concentrated that was altering her DNA so much it was causing these incredible transformations. But even the small bit of rational thoughts that had just crept into her brain didn't last more than a few seconds as her cock tensed up, pulling itself up along her stomach and nearly smacking her right in the forehead as she began to cum, hard, harder than any man, or woman, or creature from ancient mythos could ever cum. It literally began to spray like a large fountain from the tip of her giant cock head, spraying the ceiling and splashing down over her face, her chest, the floor, the toilet, sink, everywhere and anywhere a liquid could hope to fall in that bathroom, it did. It was like gallons of milk pouring from her cock, she had no way to describe the bliss as it rumbled up the huge shaft and then how it splashed over her naked bodybuilder body. Sara drank as much as she could, and sucked on the tip as it flooded into her mouth, nearly choking her, but she didn't care, it was like some sort of honey tasting drug to her now, and she couldn't stop herself from devouring as much as she could get. Several long minutes passed before the shocking pulse waves of pleasure slowed and her cock went from firehose to leaky faucet, slowly but surely starting to shrink down to a more managable size, maybe a foot long in it's quickly flaciding state. Sara suddenly felt weak as she quickly sat down onto the cum soaked toilet as her racing heart finally started to come more into a fast but steady beat. It could have taken hours for all Sara knew, she'd completely lost track of time and her normal state of mind during the whole thing. She was still so much in shock that it took her a while to realize that she was still very bulked up compared to her normal self. Her legs, her arms, breasts, even her hair was longer, stronger and definitely bigger in every way. She took a long look over herself and then the sorry state of the bathroom as she thought about just what she'd went through. If she'd not been in this enhanced state of body and mind, she was sure that her cumming session would have killed her. Maybe her body went through the transformation to prepare itself for the oncoming onslaught of pleasure? She wasn't sure, not of this, really not of anything anymore. The serum had grown so far and away beyond any of her original designs that it was a completely new invention.

Sara's relief ended abruptly when she felt heat pulse through her, spreading from her chest all the way down to the tip of her flacid cock, the feelings made her gasp as she felt her breathing pick up while her mind was suddenly filled with lustful images of cocks, naked men and women, pussies and being fucked by huge oozing cocks. Sara grunted as she stood up, holding her head as her glance moved downwards in time to watch her nipples erecting quickly, filling with blood as they expanded outwards, turning purple and rock solid as her breasts began to swell, the sound of milk filling them was undeniable. Sara turned away from the mirror, not wanting to see what was happening to her again, and so quickly that it was scaring her. But heat pushing into her cock made her moan as she looked down and watched her flacid penis slowly erecting again, the veins along it's surface puffing up and starting to pulse to her beating heart. Sara could do nothing to slow it down or stop it, and her mind was pushing her more and more to see it buldge, grow and push upwards to her hot, slick mouth. She tried in vain to make the images stop, but the harder she tried, the more her cock erected, faster and faster it pulled outwards from her crotch, the muscles pulling tight, pulling it straight outwards from her pussy, then tightening harder and harder, pulling it upwards along her torso. It was like a living piece of muscle that was getting hotter and harder with every hot breath Sara took into her lungs. Her eyes widened as it slowly creeped up her stomach, reaching her breasts in seconds, it's swollen red tip growing wider and the shaft grew in girth until it was easily as big around as a human arm, complete with thick rough bumpy veins pulsating along the skin. She couldn't believe what was happening to her, even if her mind was screaming that it wanted it, Sara knew this was getting dangerous. If things went too far, or this thing didn't stop soon, Sara was certain she was going to die of heart failure or worse since the human body was never meant to be put through this much stress, regardless of how wonderful it was making her feel, something else that worried her. Her body wasn't listening to her pleas of course, as her cock pulsed and slammed into her chest as it reached all the way to her chin, threating to beat her in the head if she didn't start using her sexy mouth on it soon. Sara had no will to resist the temptaion of her own cock and slipped it down her throat as far as she could, sucking and rubbing her swollen, milky breasts up and down the shaft at the same time. Sara felt every shock of pleasure, every single fiber of her skin felt as though she had a cock up inside her pussy, the feelings were indescribable without having experienced it firsthand. The already massive head of Sara's cock began to swell even larger as the underside of her cock turned hot white, cum being loaded into the shaft quickly as she felt the rumble of oncoming orgasm. Even knowing what was coming Sara had little time to prepare or react as she climaxed, both from the huge tip of her massive cock and from her dripping pussy. Her cock let loose with a blast of hot cum that resprayed the bathroom and just about everything in it in another layer of creamy white fluids. Sara drank as much as she could just as before, and she loved the taste, but now her energy was wanning as she slipped slowly down and onto the floor, barely remaining conscious as her nipples and cock shrank down to normal flacid states. Slumping to the floor, Sara tried to catch her breath as best as she could, and also tried to keep her mind as blank as possible, in hopes that if she didn't think of anything or anyone, her mind might cut her a break and not twist her thoughts into something sexy or lustful.

It seemed to work for the moment as Sara felt her heartbeat slowing down and the oxygen supply in her lungs with finally coming to normal levels. Sara felt cold all of a sudden, the heat leaving her and the cum she was laying in. She wasn't sure what she should do since she didn't know what might set off another transformation or horny session, but she figured she couldn't just lay on the cold floor forever. Sara opened her eyes slowly and sat up, slipping a bit on the slick floor as she made her way upwards to her feet. She gasped when she saw her horrible complextion in the mirror. She was white and covered in cum, a lot of it matted to her hair giving her sections that looked like dreadlocks. She was still muscular and taller, with longer hair, bigger breasts and pretty much a perfect body building type body, things Sara didn't really want. Not that she didn't like how she looked per se, it just didn't seem natural to her to look this way, especially with a flacid man's cock hanging from the top of her pussy. A small tinge of a thought did creep into Sara's head as she stared at herself in the mirror, a sexy thought, a cute little thought, maybe the wrong kind of thought. Sara let out a small gasp as she thought to herself how strange it might be if she could somehow stick her own cock into her own pussy and fuck herself as it grew bigger and hotter inside her. This thought began to fuel another fire that caused Sara to immediately snap to attention while she spouted out a long string of curse words in a row as to why in the hell she'd let herself think something so stupid. But it was already too late for her now and Sara knew it too as she watched her nipples starting to expand outwards as they hardened into hard, hot, purple points.

Sara spun around and bucked her hips outward as pleasure once again rushed through her body, even as it tensed once more, expanding her muscled body with veins full of hot blood, most of which began to fill her hardening meat rod. But oddly, Sara watched with her mouth open wide as her cock tilted downwards rather than upwards, in fact, it seemed to be curving in a way that was putting her cock into a direct collision course with her pussy lips. Sara's eyes widened when she realized that her dirty little thought about fucking herself were becoming a full fledged reality right before her eyes. Her cock continued it's curve and growth and Sara knew there was no point in fighting it at this point, her stupid brain had started this rollercoaster and now she'd have to see it through to the end. Sara gasped as her cock pushed into her wet outter folds, spreading them slowly apart as inch by inch her cock expanded and extended, curving in the most impossible way she could think of. Her rational thoughts did little to stop her cock from pushing past her outter folds and growing right up past them, opening her cunt wide as it entered her vaginal cavern of pleasure. Sara's head snapped back and she yelped and bit her lip as she felt the hard, hot cock pushing deeper up into her, and she spread her legs a little wider to help it on it's way. One inch, two, three, then four inches into her and still growing, then five, six, seven and more made Sara start to drool as she panted and moaned. She could feel it's girth expanding inside her, first only an inch around, then two, then three, it was almost impossible to imagine or describe in her state of mind just how it felt for her to feel not only the pleasure of a cock inside a pussy, but to feel her own cock inside her own pussy was just insane. Her cock tightened it's muscular mass and pushed another three or four inches up into her and then began to throb hotly, the veins along it's surface pulsating to her racing heart, making the entire length hot as a frying pan. Sara was lost in a battle between heaven and hell, unable to move, barely able to breath, and unable to escape the feelings flowing over her body. Her nipples were leaking milk in a steady stream and her cock, on it's own, was starting to push in and out of her aching pussy, using some new muscles that seemed to have just grown inside the giant hot rod it had now become.

Sara took her own nipples into her mouth, suckling milk from one, then the other, in an attempt to alleviate some of the pent up pleasure, but it only made her nipples harder and her cock bigger. Sara began to moan louder, begging her cock to ram into her, to fuck her hard, to give her some release, and amazingly it obeyed, and with a passion. Sara almost slipped to the floor when her cock began to pound into her like a jackhammer with way too much air pressure, but it felt so wonderful, so impossibly awe inspiring, that she began to cry. Her cock rode her like a demon possessed, and Sara thanked herself that she hadn't thought of that beforehand as she spun around and leaned over the counter, letting her cock spread her as wide as possible, sinking the whole of it's burning shaft into her. Sara was leaning on top of her giant, milk engorged breasts, thanking that at least she had some cushiony flesh bags for this part of the fuck tour she was on because her arms would have failed her long ago. At this point Sara didn't even know what time had passed since she'd woke up and came to the bathroom, and this point she really didn't care. This time honestly her mind almost went totally blank as she neared orgasm, not just with her pussy, but with her cock as well. She could feel the tip of her cock swelling, the muscles tightening, the shaft getting even hotter as it loaded cum into it, she knew it was now or never. She leaned up from the counter, her nipples starting to spray milk all over the mirror as she came, harder and faster than she thought a human in any form could ever cum. Her pussy sprayed cum all over the top of the counter, and down the sides of it on top of that, in several long, hard, hot, sticky waves. And her cock felt like a firehouse rammed up inside her as spray after spray shot up into her vaginal walls, another feeling that felt even more incredible since it was her own cock and not Ron's. She still couldn't describe the feelings it gave her, nor did she want to, in fact she almost didn't want it to end, almost. But finally, several long minutes after her eruption to end all eruptions, her Krakatoa so to say, Sara felt her cock shrinking quickly, slowly but surely sliding from inside her until it was left hanging and becoming smaller and returning to a more clitorial state only a few inches long. Sara's milk supply also dried up, and though still much larger than her normal breasts, they were no longer full of milk. or at least, no longer as heavy as breasts filled with milk. She slid down onto the cum and milk drenched floor once more, panting and almost ready to black out. Her body was drained, her oxygen levels were in the red and her cunt ached like a dickens. But still, Sara smiled weakly, knowing full well that her experience, though stranger than anything else in her life, wasn't all that bad and in fact, it may have opened to the door to all new experiences if she could figure out exactly what her serum had done to herself and Ron. She was certain it would take time to figure it all out, but she was also sure she'd have plenty of time to do so, especially if she had Ron to help her.

Ron! She'd almost forgotten about him! Sara was shocked into being wide awake and well aware of the state of her body and the bathroom. The room was pretty well soaked with dried and drying cum and milk, almost no surface was left untouched by her explosive orgasms. Sara slid over to the small closet next to the toilet and was relieved to find several towels that she immediately used to wipe up some of the goo on the floor around the tub. Of course no towel had the surface area needed to clean up the mess she'd created, so the best she could do was clean off a small square on the floor big enough to make it out of the room without slipping and killing herself, but first she thought it was best if she got a shower. She turned on the water and let it get decently hot before stepping up and into it, shivering as the hot water soaked her but thankful that the cum and milk washed away quickly and easily, even the copious amounts on the wall tile around the tub. She tried to wring out the towel she'd just used on the floor, but it wasn't about to come clean that easy, so she ended up just using it to scrub the tub tile wall clean of any jizz that was left after she had sprayed it down with the hot water. About ten minutes later, Sara finished showering and was pleased to see herself back to a mostly normal state now. Her breasts were still bigger than normal, her hair was still pretty long and so were her nails, but her clit was vaginal area were clean and looked normal enough and she was breathing normally and didn't feel horny or hot at last. Normally she'd be pretty happy about it, but looking past the tub to the utter destruction she had brought upon Ron's poor bathroom made her unhappy. Sara slowly turned off the water and got out of the tub and dried off with one of the few remaining clean towels, and carefully made her way out of the bathroom using the square she'd cleaned off. It was sticky on the floor even without the cum there, but she made it out of there alive at least. She wrapped up in the towel and made her way to the bedroom door, slowly giving it a tug open to look outside. She saw him sitting at the dining table, enjoying what looked like toast and eggs and bacon. Suddenly Sara was really hungry.

Sara walked out of the bedroom and headed over toward Ron. He was reading the morning paper, but looked up at Sara as she made her way to the table and smiled, asking her how she felt. She told him everything that had happened and he came over halfway through her first few sentences to hold her hand and comfort her. Ron asked a few questions of his own, trying to get some reassurance that everything was going to be ok from a scientific standpoint. Sara realized he was trying to get het to think in her logical Vulcan mode to help calm her down emotionally, which made her feel a lot better. Though she assumed that the worst was over, she honestly was not sure that all the changes from the serum had, or possibly could in fact work their way out of their system. It was possible that the effects would stay with them, or maybe it altered their DNA to the point where it'd be like a disease that could have relapses. Ron didn't like the idea of his cock suddenly growing three feet long at work out of nowhere, unless of course Sara was there to help "cure" him as he gave her quick kiss on the cheek. Sara giggled but tried not to put any thoughts of a three foot cock into her mind, she knew she couldn't handle it, not another transformation into Pussy Cock Sara, super heroine of the city. Ron and Sara both giggled together and Ron asked her what she'd like to eat for breakfast, making sure before she said anything that he was not on the menu. Sara smiled and acted as if removing Ron from the breakfast menu was a bad thing, to which they again shared a laugh. Sara had three eggs, four pieces of toast, a tall glass of orange juice, five strips of bacon and a bisquit. Yeah, she was hungry.

After breakfast the two of them went to check on the damage to Ron's bathroom. After his initial shock he laughed pretty hard, almost thinking it wasn't even real milk and cum sprayed everywhere. Sara pinched him making him yelp and then looked at her with puppy dog eyes. Sara giggled. Ron assured Sara that it'd be ok, he'd go get some towels from the other bathroom and clean the stuff up before it all dried too permanently. Sara said she'd help but Ron asked her to take a load off so as not to worry about it and instead go hang out on the couch and watch some TV. He figured after her morning, she would be better served getting some rest and relaxation. Thinking Ron was being such a gentleman, she decided that she had earned a small load off her mind and took him up on the offer. After getting one of Ron's big t-shirts from his dresser drawer to cover herself with as best she could Sara thought it was probably best for her not to mess around working too hard right now. After a quick kiss for Ron, Sara went to the living room and sank into his awesome couch, flipped on the tube and started surfing. Ron got to work on the bathroom cleaning, soaking several towels clear through in seconds due to the thick layer of cum on everything. Though a lot had dried, there were several thick places on the floor and the counter that weren't. Ron was getting a lot of it on his hands and arms, once slipping and landing almost face down in one of the puddles. He tossed the towels into the tub and figured he'd wash and rinse them out once he was done. It took him about an hour to get the floor cleaned up and at least another thirty minutes to clean up the toilet, the mirror and the sink's counter. The walls that weren't tile would need to be scaped and repainted, so that was the only real loss. Ron figured it wasn't that bad really and tossed the last gooey towel into the tub. Before he could turn on the water though, Ron felt a little tingle roll through his body, a nice warm little thing that made him think of Sara. He stopped and turned to look out the bathroom door before going out and peeking out to the living room to look at her. He could see how beautiful she looked, even though her hair was still wet and she was wearing one his t-shirts. He knew she was naked under that thing though, her bare little pussy was all clean and would probably taste so good right now, and her breasts were a lot bigger now. Those breasts she had now, God it all started when he first saw them at the office, easy F cups, now at least GG cups. Breasts that were firm and with nipples as big as a thumb on top Ron thought to himself. How good it must feel to have breasts like that he thought, big, firm, sensitive breasts that you just love to suckle on and roll in your hands.

Ron's heartbeat started to pick up and he started to breath heavier. He stared through the door at Sara, visuallizing that body of hers, wanting her so bad all of a sudden. His cock started to erect inside his shorts, quickly pushing them out like a tent pole, but it wasn't stopping there. Even in a daze Ron was starting to become drenched in sweat, his body was starting to twitch and so was his cock as it strained to be released from the burden of fabric that was trying to contain it's buldging mass. It erected outwards into the wall, but thankfully it didn't keep growing like the night before. His body seemed to have decided on keeping Ron's cock only two feet long, though it did start to thicken and tighten, pulling upwards toward his stomach, hindered only by the elastic in his shorts. Precum began to dribble from the tip of his engorged cock, already seeping through the fabric of his shorts, but as his heartbeat picked up even more, more changes began to pulse through Ron's body, changes he'd never notice as his mind went blank and his eyes glazed over. Ron's body spasmed and he leaned onto the wall for support as a creaking sound began to fill the air. Ron's fingernails began to grow longer, sliding further from each cuticle until they were over an inch long. His toenails did the same thing, giving him perfect nails in just a few seconds. Ron's hair began to come to life as his short black hair began to lengthen, curling from the top of his head as it began to grow longer, flowing down the sides of his head and touching his shoulders quickly. The rest of the hair on his body actually began to recede into his skin, first with his slightly unshaven face hair, followed by his chest and arm hair, and finally any other hair on his legs, back and pubic area. In a short time, Ron's body had become soft and smooth to the touch, even if he was only able to let out small moans with his eyes closed, lost in a fog of pleasure and lust. His hair was still growing and already starting to thicken into rich, full locks that now reached down to the middle of his back. Ron's face was starting to pulsate as sweat dripped down the sides, his eyebrows were thinning out and the contours of his face were losing their squareness and becoming softer and more round. His lips seemed to puff up and become fuller and slightly wider while his nose became small and thin, perfectly matching the rest of his new, soft face.

Every bone in Ron's body was cracking and shifting as his shoulders seemed to cave in toward his neck becoming smaller and petite like, unlike the wide manly shoulders he had all his life. His arms were losing their muscle and even his fingers were thinning out and growing slightly longer, more delicate fingers, more womanly fingers! Ron's hair was almost down to his ass just as his hips seemed to crack and begin to flare outwards, pulling his shorts tighter while his ass cheeks expanded and rounded becoming soft yet firm, pulling his shorts even tighter, while his cock began straining the fabric in the front to it's breaking point. The rest of Ron's body seemed to be losing all signs of muscle and flabbyness as his skin tightened and became just slightly tanned all over, giving him an overall sexy, female look from the back. The hair on his head finally stopped growing once it had reached the back of his knees, and had turned from black to a beautiful brown, with locks that the best stylists in the world would love to give a woman. Ron moaned as a tingle raced to his crotch, causing his cock to swell and tighten in his pants so hard his shorts began to tear open in the back, pulling the elastic past it's limits. He began to rock his hips in and out as though screwing an invisible pussy, his breathing now ragged and coming in quick bursts. Inside his tight shorts Ron's scrotum began to churn as his testicles swelled in size until they were almost as big as baseballs making him moan outloud as his cock clenched hard, spraying hot cum all over the inside of shorts, soaking them in the front like a firehose. Immediately after however, Ron's testicles began to shrink inside his scrotum until they were pulled upwards, pulling back into his body as the outter skin of his scrotum began to split open in a line that ran from the bottom to the top, near his cock. The skin opened up slowly and began to change texture and muscularity, becoming a lighter pink and puffing up. The skin and folds started to sink back into Ron's crotch, almost like it was forming a pathway up inside him, just below his throbbing cock.

Ron spread his legs as he leaned against the wall as each passing second made him feel hotter and hornier than he could remember in his life. Inside his shorts his skin continued to swell and buldge as well as push deeper inside what could now be considered a woman's honey pot. The skin of his scrotum had completely shifted into the hot, pink outter folds of a woman's pussy lips and as the rest of his skin pulled further up inside his body, he moaned as his insides began to churn, giving him a full on woman's reproductive system in only minutes. Ron spun around, putting his hands wide onto the wall, leaning over and thrusting his ass outwards as his shorts finally had enough of the strain, snapping apart at the waist and slipping down onto the floor. As Ron moaned his new pussy lips and vagina finished fully forming and no sooner had it done so than it began to drip with his new female hotness, a buldge appearing from within it's slick outter folds as his clit swelled into a giant, hard ball as it became erect. More tingling sent chills down Ron's spine as his chest began to feel hot, causing him to bite his lip and moan again, his nipples hardening into thick points inside his sweat drenched shirt. Under his shirt, his skin began to pulsate and shift, his nipples suddenly swelling much larger than any man's, his aerola puffed up and began to darken and grow larger in diameter. Ron moaned again as his skin began to tighten and his chest began to swell, slowly at first, but picking up and swelling faster with each breath of air Ron took.

Ron's cock was also in on the feelings shooting through his new body as even after cumming so hard only minutes before, it had returned to it's thickened, hardened state once again. Ron almost screamed as one of his hands grabbed his hot cock, and the other reached down and shoved three of his fingers into his hot cunt, pumping both sexual organs with all his might. It took only seconds of stimulation of cock and pussy at once before Ron's head snapped back, his eyes snapped shut and he moaned loud and came hard. His cock shot hot cum all over the wall in front of him and his pussy covered his legs and floor as it shot it's hot honey out with great force. Ron's legs became weak and he slowly slid down the wall and onto the floor, panting heavily, his mind clearing quickly. He sat there panting for several minutes before he snapped to attention, suddenly aware that something weird had happened. He barely finished thinking that when he looked down to see his chest expanding outwards into his sweat soaked shirt, his erect nipples very visible through the soaked fabric. Ron's eyes widened as he saw he was growing breasts, large, firm, fleshy orbs of such a magnitude he thought he had to still be dreaming. He reached up and grasped them in his hands and instantly let out a low moan from the feelings that shot through him. He felt his flesh squirming in his hands as his new breasts continued to swell outwards into them, pushing his fingers apart and causing his nipples to thicken, lengthen and harden further than he'd ever dreamed them able. Ron couldn't even understand at this point what was going on and did his best to stay as calm as possible while he got up off the floor, carefully avoiding his puddle of cum, as he made his way over to the mirror.

Ron almost let out a scream, but moaned as he felt his breast's growth slowing to a stop. In his aroused state, he also immediately felt them firm up while his aerola puffed up which in turn also made his nipples harden and engorge until they were turning a light purple color. Ron was stunned after his attention could leave his chest and move upwards to take in his mirror image. Sara's name escaped his lips, and his hands immediately went up to cover his mouth, shocked that he not only looked like Sara, but now also sounded like her. At least until Ron looked down between his legs and saw his flacid cock hanging from the top of his new vagina. It was a little bit bigger than his normal cock, perhaps because of his current transformed state, and just looking at it was already starting to make it harden. Ron didn't even want to think about what was going on but even as he turned away from his reflection, something deep inside him stirred, a warmth that started to fill him from head to toe. The warmth began to center on his crotch, and most insistently, his pussy. Ron turned back to the mirror and slowly slid his hands under his wet shirt and took it off, letting it slip to the floor. He gasped as he realized he was doing something he shouldn't be, but looking into the mirror he could only see a beautiful woman, a woman he loved very much, a woman that had already done some weird ass shit to them both, but loved him anyway. And he loved her too, he loved Sara, he meant what he said to her, and he knew in his heart she meant what she had said as well. Ron wasn't sure if he was feeling so good because of his new body, the serum, or his own personal feelings or not, but he knew they were definitely starting to turn him on. In fact, he was suddenly aware of how aroused he was getting as he watched his nipples darken to a deep purple as they began to throb and his flacid cock began to harden quickly, pulling itself from between his legs and upwards to stand semi-erect straight out from his crotch. Ron's hands moved up to his nipples and began to play with them, rolling them between his thumb and index fingers, feeling tingles shoot through him like a Nascar flying by him on the sidelines at 200 miles per hour. It was an ungodly feeling of bliss the likes of which he'd never felt as a man, something he couldn't even start to comprehend, something he assumed not even women could fully understand themselves.

Whatever the reasons, Ron felt hot flashes wash through him as he played with his nipples, and began to fondle his new breasts, Sara's big, milky, firm breasts. Ron watched his cock tighten quickly into a full blown erection in seconds as it pulled upwards toward his stomach, growing darker as blood rushed to fill and expand it. Veins puffed up along it's surface as it expanded in girth and length until it was almost up to his chest, a monsterous cock that made Ron's mouth water and his mind scream from even thinking about sucking on it. His cock grew longer, harder, and thicker, climbing up his torso like a snake on a mission and Ron's mind was already going cloudy. With his new body came an all new state of mind, one that wasn't all about sucking on pussy, but now with his cock standing only inches from his chin, throbbing and hot, he knew exactly what he was going to do. Ron's lips parted and his head lowered toward the tip of his massive meat rod when out of nowhere he heard his name being called, a click and a sudden outburst that was most definitely a scream. Ron's mind immediately went from hazy to terrified and put the brakes on any naughty thoughts so fast he may as well just dove head first into a river in the middle of winter in Alaska. Ron turned toward the door, his eyes wide with fear, to meet the gaze of Sara standing in the bedroom doorway, the same look of fear on her face. Her jaw was also hanging wide open in disbelief at what she saw, herself in fact. Well mostly, except for the giant cock that was now going soft before her eyes, hanging down in between Ron's legs. Sara quickly questioned her double to which it only took a few sentences for Sara to realize that it was in fact Ron. Sara ran to Ron and embraced him, and he her. She was already in tears, worried that Ron was in the mindset of hating her for what she'd obviously done to him. Ron wasn't sure what to say and while in the back of his mind he may have had a little anger for what had happened to him, on the other hand, he was alive and with the woman he had fallen in love with. On the other, other hand however, Sara's warm embrace was making Ron feel a lot more than perhaps Sara had intended. She smelled great and her breasts were pressing right up against his own, her nipples weren't hard but his were starting to erect already, he could feel it. Ron had to say something and so he told Sara that while his new body was definitely a strange experience, he wasn't going to regret it and in fact, it was his own damn fault that he looked just like her, or close enough to call them twins anyway. He'd let his serum laced brain cells think too hard about how much he loved Sara, and his body simply followed those thoughts and transformed itself into his love's desire. Sara blushed and kissed him, amazed at just what a real catch of a man she had been overlooking for almost two years on the job. She couldn't picture any of her other male friends or co-workers standing up to this type of weird punishment of science. Ron was starting to get more turned on by the minute and he warned Sara that she had best get out of the room, in case his cum sprayed her and kept the circle of fucking going around and around.

Sara looked down and watched Ron's cock erecting quickly, growing up into her crotch before pulling tighter and harder, pulling straight upwards along Ron's stomach. Sara began to rub Ron's thickening cock with her hand and giggled when the pleasure made him moan. It was her own voice and she never realized how sexy it sounded until right then, and despite Ron's warnings, she found herself already getting too aroused to stop herself and Ron had no willpower to stop her either as he was already so hot he was practically begging Sara to suck his cock with his eyes. His new pussy was wet and dripping and gave Ron such an alien, yet very pleasurable feeling that he was at odds with his own body. His head snapped back as Sara lowered her hot mouth down over his throbbing dick, some cum spraying into her mouth almost instantly, the feeling practically knocking Ron off his feet. Sara let Ron's cock go and together they managed to slide over to the bed. Sara pushed Ron down onto the bed and climbed on top of him, lowering her pussy down into his face as she once again slipped her mouth down onto his throbbing cock. Ron began to lick and suckle on Sara's now dripping folds and had to take deep breaths from her blowjob. It wasn't like a normal blowjob now, it was a hundred times better. Ron couldn't believe how good it felt having Sara's mouth wrapped around his meat log, but it felt as if she were inhaling it rather than sucking on it. In between the grunts and moans, he came at least four times, but Sara showed no signs of stopping as she seemed to take more of his giant cock into her throat and mouth each passing minute, adding pleasure on top of pleasure everytime she went down his hot shaft. Ron didn't rest on his back either, bringing Sara to four or five massive orgasms of her own and all the while her moans made him only want to give her more. Ron and Sara licked and sucked for over thirty minutes before Sara did something that Ron had no understanding of or basis for experiencing: she pushed some of her fingers into his wet cunt. Ron instantly let out a yelp and a long moan, his legs going straight out while he spread them open wider at the same time. Sara grinned to herself as she began to pump her fingers in and out of his vagina, loving the groans and moans coming from Ron, watching as he came two or three times within a minute just from her fingers being inside him.

Thinking of more to do, she slipped her mouth off of Ron's cock and lowered her face down to his pussy and began to lick him. Ron groaned like mad, digging his fingernails into Sara's ass, nearly passing out from the bliss shooting through him. He couldn't even come to terms with what he was feeling, it was like fucking a girl but having the feeling centered inside him rather than on his cock. And he had to admit, as much pleasure as he ever got from fucking Sara or having her give him a blowjob, his cock was nowhere near as sensitive as his new vagina. It was a thousand times over the pleasure threshold of his brain, and he began to drool and mumble, pulling Sara's ass down so he could litteraly tongue fuck her pussy as fast and hard as he could. Sara was also feeling more sensitive than usual, and in a weird way couldn't really believe she was making love to another woman, a yet it was her own pussy she was eating out, whether it was on Ron's flesh or not. It was strange, but Ron tasted wonderful, like strawberries, like nothing she'd ever tasted before. Sara alternated between licking Ron's pussy and licking his cock, which she noticed was getting larger right before her eyes. The more she licked his cunt, the bigger it seemed to grow until she began to worry, ever so slightly, that she might want to get off of him and just let him fuck her. Before she could make the move however, she heard Ron speak first, and what she heard was incredible. Ron was almost begging Sara to grow a cock of her own and fuck him in his new pussy, just as he had done to her several times already. She almost choked on some of his hot cum as it splashed into her mouth from her last few licks on his hot folds as she leaned up and slowly got up off of Ron. She looked at him with concern in her eyes for the first time since they started getting into this whole thing. He slowly sat up, still very hard and turned on and promised her that things would be ok, that he had to experience all the sides of being a woman, not just the strange combinations of pleasure of having both a cock and a vagina from the outside, he wanted Sara to fuck him and he knew she could if she wanted to. Sara had to think about it for a minute or so, as the reprecussions from something like this could be bad. What if Ron's body couldn't take much more punishment and her serum laced cum pushed his body beyond any and all limits. What if he became pregnent? What else might happen that she was unable to even comprehend at this point? Afterall, nothing they both had experienced all weekend had ever been even a remote thought in hell as a side effect of the serum, regardless of how much a person injested. She turned back to Ron who only again asked her to please do him and she noticed that his cock was dripping with precum and was still very swollen and red, even larger than it had been when she was sucking on his pussy. Maybe, Sara thought quickly, that in his current state of mind and arousal, his only real release was for her to fuck him, and she felt almost obligated to do it, since it was all her fault they were in this situation in the first place.

Sara leaned over and gave Ron a long French kiss and smiled at him, nodding and telling him it was ok, she'd give him some paybacks for the last couple of days. Ron smiled back and decided to help her out as he moved behind her and reached around and began to kneed on her breasts with both hands, twisting her hard nipples and nibbling on her ear and neck. Sara shivered at his touches and nibbles, finding it amazing that he knew just where she was most sensitive, and it made her love him that much more, and it began to really get her into the mood she wanted to be in. Then she heard Ron whispering in her ear, whispering how much she will like having a big cock sticking out of her pussy, how big it'll be, how hot and hard, how nice and thick the veins will be on the skin. Sara couldn't believe just how bad the serum was effecting Ron's mind, making him almost desperate to have a cock inside him. Though his whispers were having they're own effect on Sara, as she slowly closed her eyes and began to picture just what he was describing to her. Ron told her how good it'll feel to let her clit grow from deep inside her, bigger, harder, thicker, and hotter, all the way out of her pussy, then up to her navel, then growing bigger than that, up to her chest, then her chin. A two foot long, thick, hot, hard, veiny cock full of hot cum that would fill his tight pussy and fill his insides and make him scream and moan her name for hours on end. It'd be so big and hard, even he'd be jealous of it and it'd make Sara feel so good as his pussy lips grip it and she moves in and out of his hot cunt. Sara couldn't believe how much Ron wanted this, but his words really turned her on and she felt her heart begin racing as she started to whisper how much she wanted a cock like that, a big, thick, veiny cock even bigger than Ron's. Her nipples hardened and expanded outwards several inches, which grew harder than steel as Ron played with them and her breasts firmed and tightened as they began to fill with hot, sweet milk, stretching outwards slowly. Ron took noticed and slid around to Sara's side and began to lick and suckled on her huge purple nipples. The sensation was incredible for Sara, far more pleasurable than simply twisting on them by herself.

Then she felt it, the pressure, the hardness, the heat building and building inside her pussy, her clit bulging, pushing outwards, past her soaking outter folds. Sara began to pant, but she felt a hand starting to rub on her hardening, thickening clit, and she nearly fainted. She opened her eyes, panting and blushing like mad as she looked down at Ron's hand stroking on her growing clit, giving her no way to hold it back because it was as if he were almost pulling it from inside her. Sara began to drool it felt so good, and she was hornier than even the serum had ever made her and as she watched her clit swelling and growing larger and thicker, she knew she was as happy as human could be on this Earth. She yelped and groaned as Ron licked her neck and suckled on her nipples, causing her clit to gain several inches in girth and length as veins began to grow upwards along the growing shaft. Sara watched the tip split open to form the slit of cock and she had no intentions of stopping it from getting as big as Ron could ever want. It grew past her navel, then further upwards, stiffening into a hardness that could rival Wolverine's Adamantium Bones as it pulled straight up against her torso, still growing upwards. Ron had to move his head to give it room to grow, and even he couldn't believe he was actually wanting this thing to be stuck right up inside him. But the longer he watched it, the more watery his mouth became until he couldn't stand it any longer. He surprised Sara with a loving tackle that sent her over onto her back and even as he climbed on top of her and began to lick on her still growing cock, Sara no way to stop him. Pleasure shot through her from not only Ron but her own desires of growing the cock he was now licking and sucking on. She loved it, she loved Ron, and she never wanted to be away from him again, it was just too incredible an experience and he was too incredible a man. Her cock grew even thicker as it finally stopped growing at about her chin and Ron was practically laying on the thing and licking it with everything he had. His pussy was such a dripping mess that the whole shaft was soon covered with his juices. It was throbbing madly and hot to the touch, almost causing Ron's love juices to steam right off the thing. Only a few minutes passed before Ron had his fill of foreplay and fondling, and he leaned back, spread his legs wide and with one hand he opened his pussy lips for Sara to see. She knew exactly what he wanted, and that he was now at his most desperate, but now Sara was as worked up as he was, and whatever small bit of logic that remained would not be enough to hold back the oncoming flood of bliss she was about to insert right up inside Ron's dripping cunt.

Sara fought the immediate urge to ram her cock into Ron with force, knowing full well it was going to hurt him, so she placed the tip of her dick right up to Ron's dripping love canal and slowly began to push it up inside of him. Ron gasped and yelled as it slid deeper into him, causing him to slam the bed with his fists and grip the sheets hard. Blood began to find it's way from between his dripping folds, mixing with his juices as the sheets became stained with blood and cum. Sara tried to comfort him, and he managed a weak smile as his legs wrapped around Sara's back very slowly as he began to pull her into him deeper and deeper. Sara was moaning as well, her new cock felt so different than her pussy, and yet it was still almost as sensitive. Ron's pussy was hot and tight, and she felt her massive cock rubbing his insides as she plunged it deeper and deeper into him. Finally, after what seemed like an eternity, their pussies touched, and all two feet of Sara's hard cock were inside Ron's pussy. He was taking short quick breaths as she paused to let him try to get used to the alien feeling not to mention to let any pain she was causing him to subside before she began to move. Several minutes passed before Ron closed and his eyes and Sara felt his vaginal muscles starting to grip down onto her cock, letting her know he was ready to fuck. Sara wasn't the best at this, but she'd seen enough porno movies in her time to know the basic idea of how to do it like a man, and so she began to slowly buck her hips to and fro, pulling her cock about halfway out of Ron's cunt, before pushing it slowly back inside. Ron held up his hands and Sara gripped them in a loving hold as she picked up her pace a little at a time. Soon, both of them were getting into a nice rythme and Sara began to push a little harder and faster, and Ron began to move his hips more in tune with her motions, gripping down on Sara's cock with each massive thrust. He was going crazy with lust and pleasure, screaming Sara's name every few seconds, pulling her hard into him with his legs everytime she pushed into him. For Ron, the feelings rippling through his body were without words, he simply had no way to describe how a man's cock felt being inside of him while he was transformed into a woman, but he knew he'd never forget the feeling, the utter bliss it gave him. Sara grinned and let go of Ron's hands as she leaned down a little further, and took ahold of Ron's cock, pulling it upwards ever so slightly, gripping it's hard, hot shaft carefully and began to jerk him off. Ron practically squeeled out loud and began to cum hard only seconds later. Hot cum began to shoot from the head of huge cock, running down all over his hot shaft and spraying all over Sara's hands and arms, covering his stomach and soaking the bed. Sara giggled and panted, nearing her own explosive orgasm even as she licked Ron's cum from her hands, watching his cock stiffen even moreso than it was a few seconds ago.

Sara picked up her pace and jammed her swelling cock into Ron as hard as she could, making him almost pass out from the pleasure. She felt his vaginal muscles tighten harder around her prick, and knew he was about ready to blow harder than any winds mother nature could slam into the east coast of the United States. Sara began to moan and groan, and grabbed a hold of Ron's hands and they both squeezed each other tightly, with Ron pulling Sara as hard into him as he could just as Sara exploded inside his pussy. Ron gasped and screamed as he felt his insides filling with the hotness of cum as splurt after hot splurt shot from Sara's engorged cock. Sara kept cumming, harder and harder with each blast letting loose with the force of a small firehose inside his pussy. It wasn't long before the hot cum began to seep out between Sara's rock hard cock and Ron's soaking folds, sinking into the sheets and mattress, going clear down to the floor underneath it. Amazingly, it took almost fifteen minutes for the blasts of cum began to subside and Sara nearly collapsed in a heap onto the floor. Ron himself with exhasted and his cock finally became flacid, shrinking down to a normal sized cock before returning to looking like a woman's clit before it also pulled back inside him, his arousal levels returning pretty much to normal. Even though he was about to pass out, Ron slowly crawled to the edge of the bed to check on Sara, who was laying on the floor, breathing heavily. He slid down to the floor beside her and laid up against her, trying to comfort her. She slowly rolled over and stared at Ron in the eyes, letting loose a small smile. Ron smiled back and they kissed each other deeply before they embraced in a loving hug just before passing out together on the floor.

It was well into the evening when Ron and Sara woke up, still covered in sweat and cum, laying on the floor. Ron noticed immediately that his body was back to normal. No breasts, no giant cock, no pussy, he was as normal as he was before he went to clean up the bathroom. He looked over at Sara who was weakly yawning, noticing that she was also back to normal, letting out a sigh that nothing else had happened to them. Sara sat up slowly and asked if Ron was ok, to which he replied that he felt fine. He thought that perhaps they were finally back to normal, as nothing about them seemed out of the ordinary now. Ron's cock was the same size he had always had before they met, Sara's hair was back to shoulder length and her breasts were now their normal D cup size rather than DD or E. Sara smiled and they embraced and kissed each other, thinking had finally used up all the serum in their bodies and that now things would finally be back to normal. The two of them got up and went to get a shower. They showered together and though neither of them could keep their hands off of each other, they didn't seem to change in any way, and for the first time since Ron had drank the serum, they had a normal fuck session that didn't get weird whatsoever. When they finally went to bed, it was with love and normality, not giant cocks or furry breasts. They slept very soundly and normally for the first time in almost three days.

The next day, Ron and Sara awoke as normal as any other day, and made it to work without any issues involving the serum. Sara kissed Ron goodbye as she went to the lab and told him if she found anything out, she'd tell him about it over lunch. He wished her luck and got to work doing his own job. His boss came to make sure that whatever he had on Friday was gone or to see how he felt in general, to which Ron had little trouble convincing him that he'd ate something bad for lunch and had gotten a mild case of food poisoning. After a brief update on what he wanted done that week, he left Ron to his work. The rest of the morning went more or less without any trouble outside of the usual office hangups: people were missing their staplers, or they were out of staples or paperclips, the copier was on the fritz or jammed and all other silly little office quirks. Ron was only smiling as he was just glad the serum had not destroyed his life in any way. In fact, he was so happy with the change of events over the weekend, he was thinking of just flat out proposing to Sara at the end of the week. He was amazed she had been so open to his odd quirks while he was female, hell, he was happy to have shared her own wild adventures anyway, regardless of what happened. Ron suddenly felt a light tap on his shoulder and as he spun around to see who it was, Sara pressed her lips to his and gave him a quick kiss on the lips, being sure nobody else saw it. She whispered to him that she had gotten a ton of data gathered so far, and needed to sit down with him over lunch to tell him what she knew. Ron agreed and grabbed his wallet and jacket and they both headed out to lunch at a little restaraunt that served great pasta.

Sara smiled at Ron and he asked what she had found out. Sara began and said that after her first round of preliminary tests she was 100 percent confident that the serum had in fact altered their DNA, but not their existing DNA strands. Rather it had actually added an extra chromosome that against all other explanations, had made them as close to shape shifters as anybody could want. The change was not reversable and had become permanent and unique to each of them. Ron was blown away, and asked what she meant about being shape shifters. Sara asked Ron to hold off until she explained a little more. Her main concern to get across was that they had both been extremely lucky as they had in fact had about a 60% chance that the serum would have done the exact opposite of what it had done, mutated their DNA, destroyed a strand of the helix matrix and left them as puddles of goo on the floor. Ron's eyes widened with fear, but Sara assured him that the worst case had not happened, and any risks were now behind them. It seems that the batch of serum he had drank had a fatal flaw in it's composition, creating an entirely different formula than what was intended in the first place. It seems that Sara had mixed in a few too many compounds, and a few of them had been accidently added due to contamination of their serum samples, resulting in an odd cocktail that could have completely destroyed them both. The one thing that had saved them was the very thing they thought was causing them harm: their cum. The high glucose of their cum as well as the high amount of protein and salts, had worked against the unstable nature of the serum and as a result, the massive amount of semen had actually forced it to stabilize in a matrix that allowed it to create it's own DNA matrix, which was the extra chromosome that she detected during her tests. The increased libido they had attained had came from the original amounts meant to cure the impotency in men, and that part of the serum had become a mutated "super" version of it's purpose due to the contaimnated compounds. Thus, after the weekend was over, their bodies and DNA had become stable and the serum had solidified and become a permanent part of their bodies. In short, they were now in control of every aspect of their bodies, from penis and breast size, to the length of hair or nails, to the musculature of their arms and legs, they had attained a new level of being, and Sara made it clear she had no desire for anyone else to get ahold of it. She asked if Ron could keep it a secret, if he'd stay with her, and be his husband, to stay with her for as long as they were alive.

Ron was stunned at the new developments and news, and though some of it was over his head, he thought for a few minutes about what all of her words meant. He questioned her on to how she really felt about him, had she really meant what she had said, about loving him, or had the serum been the one swaying their hearts. Sara smiled and asked Ron to look into his own heart, to tell her how he felt, and if he felt any worse off than he had on Friday. He looked down at the food menu a minute then let out small grin before looking at Sara and taking her hand in his. He explained that he had no intention of letting Sara out of his life, as long as she didn't mind continuing on with the experimentation of their bodies, regardless of the weirdness that might ensue. Sara leaned across the table and kissed him on the lips before leaning back into her chair and grinned, explaining that whatever he had in mind, she could damn well do just as good back to him. The waitress stepped up to the table and asked if they were ready to order yet. Ron nodded at her, and Sara smiled. They both ordered a large plate of spagetti with two meatballs and some cheese garlic bread. They'd need a lot more energy now, since their bodies would use more if they used their new found abilities much. Later that night, even the big plate of food they ate would come and go in a wave of sweat, love and cum.

THE END!
