Another story from The Process forums. A nerdy scientist stumbles upon a serum that will give it's user immortality, but the company cancels the project and she's left with only one thing left to finalize the results: try the serum out for herself! Contains muscle growth, lesbian sex and some hermaphrodite action! Though I'm wondering if Futanari would be closer to what I have in these stories as opposed to Hermaphrodite? Either way, enjoy


SERUM 57

Sara finished pouring the blue liquid into a beaker, finally having solved the secret of immortality, or so she had hoped. Priliminary tests showed positive results, if perhaps some interesting changes in the mice and rats, mostly involving an increase in libido. However, the experiments showed their test subjects were able to survive much more rigorous tests than ones that had not received any injections as well as living longer than other mice and rats being used. This time Sara was certain she had worked out all the bugs and was ready to move on the final stages of testing. Before she could share her newest results however, the email hit her hard and fast, saying that funding had been pulled for the project and she would be reassigned to work on a new project early the following week. Sara was crushed, after having worked non stop for the last six months to come up with an ideal solution to her serum's problems, they would go and pull something stupid like this. It was too much for Sara, she had to find out if her theory was correct. After everybody else had left for the day, Sara went back to the lab and pulled out one of the five samples of the serum she had created. Hoping that she was as smart as she thought she was, Sara put the vial of glowing liquid up to her lips, and gulped it down quickly, noticing that it wasn't as bad as she had first thought it'd be, maybe a bit bitter but not horribly bad tasting.

The pain hit Sara moments later, and she yelped as sweat began to pour from her skin, her hair starting to grow outwards from her scalp and into her face in seconds while the rest grew out of control from the top of her head, growing past her shoulders and down her back in seconds. Her muscles flexed and began to buldge tightly, pulling her lab coat taut over her sweat drenched body in seconds. Her sleaves gave way first, then the buttons on her jacket let loose, plinking to the floor one at a time until her coat exploded outwards revealing giant swelling breasts barely contained by her shirt. Sara could barely breath as she felt fire racing through her veins, watched as her veins stood outwards on the top of her skin as her muscles gained in mass, ripping her sleaves to shreads as her back muscles flared and tore her coat apart. It fell in taters to the floor as her legs began to rip her skirt and stockings apart, the zipper pulling itself down as her shoes ripped at the seams, her growing feet unable to be contained by such a thing as shoes. Her breasts heaved with each breath she took as they gained pound after pound of muscle and flesh, pulling every button of her shirt to it's limits before one by one they failed. With the last button giving way, Sara watched as her massively huge breasts fell outwards into the open air, her nipples instantly growing to three inches long. They turned purple as pressure built up behind them as Sara could hear a gurgling sound coming from her breasts, and she gasped as she realized it was probably milk being produced at an exponential rate, one of the side effects observed in the mice and rats they had used to experiment on. Sara's ass expanded as she leaned over a counter for support, ripping what little bit of skirt had remained on her hips apart at the seams, leaving her with only her panties to show that she had once worn clothing that day. Her panties were straining to contain Sara's increased mass, but a hot burning sensation filled Sara's crotch, and as she turned and leaned against the wall she watched in horror and excitment as a giant buldge appeared in her crotch, quickly expanding outwards and ripping her panties completely to shreds. Her clit had somehow formed into a giant penis and it was growing harder and longer with every breath she took into her lungs. At about two feet long and three inches in diameter it stopped growing and began to throb hard, giant veins puffed up on it's surface, awaiting any signal to begin loading ammo into the shaft.

Sara's mind was rapidly losing rational thoughts as animalistic thoughts began to rule her mind. Her cock was pounding, her breasts were starting to leak milk and her pussy was dripping honey down her legs. She was in heat and she needed to fuck somebody and fast. Each second that passed Sara's cock seemed to tighten and grow even larger, and her breasts started to expand further pushing milk from her engorged nipples as they too expanded outwards and began to thicken and throb. A sudden thump averted Sara's eyes from her body to the door. An office worker, Kelly she thought of the name, had come in to drop off a few things. She was in the office right next to the lab and in seconds, she'd be coming into the lab to check on Sara as she always did when she worked late. Sara's mind raced with anticipation and horror that Kelly was going to be raped hard, and there was nothing she could do to stop herself. Sara's body moved almost on it's own, the need for sex far too great to repress as she saw Kelly heading for the lap door. Sara was crying as she saw the door open and Kelly had little time to scream as she was suddenly thrust to the ground by a hulking beastly looking girl. Kelly tried to scream but found her mouth suddenly stuffed with the tattered remains of Sara's panties. Sara wasted no time ripping Kelly's pants off and then her panties, placing her hot cock right up to her pussy's outter folds. Sara tried her hardest to stop herself but all she could even mutter between growls and grunts was "Kelly...I'm...forgive..meeeouu". Kelly's eyes buldged from her head as Sara pentrated her to the hilt, a monster cock as big as human arm spreading her beautiful pink pussy lips apart, and then repeatedly getting thrusted into and out of quickly and with purpose by what she had always considered her best friend.

Sara was drooling and her eyes were rolled into the back of her head, her thrusts and grunts putting her purely on instinct alone. Kelly was crying, half in bliss of the feeling of being fucked this way, half in disgust and terror of what had happened to Sara. It looked like Sara anyway, despite being at least seven feet tall and covered in muscle. In the back of Kelly's mind she'd always wanted to fuck Sara. She was bisexual, and she thought she could get into Sara's pants if she really tried, but not like this, she never expected this. Her thoughts began to fade into nothingness as she began to cum hard several times in a row. Kelly grunted as she was suddenly pulled up off the floor and held with her arms behind her while Sara penetrated her from behind, easily supporting her weight with her giant legs of steel. The fucking session went on for hours, Kelly's pussy starting to ache both in pleasure and in pain, and Sara about to pass out from the amount of cum she had spewed into Kelly's hot pussy. Finally Sara began to tire and the effects of the serum began to wear off. Both girls slipped to the floor and passed out, covered in sweat and cum, Sara began to revert to normal soon after while Kelly fell asleep, still half clothed.

Sara woke up first, horrified by what she saw on the floor around her. She was naked, sweaty and cold, covered in dried cum. She saw Kelly laying there half naked, covered in cum and motionless, but yet, alive. Sara was scared now, she knew she'd raped her friend, oh God, she'd raped her best friend, what in God's name had she done to herself she thought. She slowly got up and grabbed one of the lab coats off the rack, covering herself with it before pacing back and forth, searching for an answer. Kelly would wake up soon and there'd be charges pressed, Sara would go to jail or worse. Why had she been so stupid, so reckless? In the name of science it's necessary sometimes, but this was just too much, she could never forgive herself for what'd she done. She heard a moan, she looked down as Kelly stired from her slumber, looking directly up at Sara. She told Kelly what had happened and was ready for a vicious back lash by her at what she'd done. Instead, Kelly gave her a hug and a kiss, right on the lips and explained to her what she'd always wanted to do to her. Taken back by the sudden realization that Kelly was in fact a bisexual, it didn't ease much of the emotional upset the serum had caused. Perhaps she'd have been ok making out with her, but not raping her like a wild beast. Sara's attention was brought back to Kelly who was standing in front of her, now totally naked, having taken off the rest of her clothes. Sara gasped as she felt her heart skip a beat, the look of lust in Kelly's eyes was undeniable. Sara tried to keep Kelly away, but she slipped right up to her and began to nibble on her neck, then on her lips. Her hands reached behind Sara and began to squeeze her tight ass and her kisses began to turn her on. Sara couldn't understand, her mind was starting to get cloudy as Kelly opened her lab coat and began to nibble on her hardening nipples. Sara gasped as she felt the heat returning to her veins, her eyes widened as she realized she was going to change again, she would rape Kelly again if she didn't stop this, but she couldn't, she wouldn't, Gods help her she wanted this girl, she wanted to ram her full of hot cock. Sara's mind was already going when Kelly felt her nipples expanding inside her mouth, hot milk spraying into her throat everytime she suckled hard. She felt Sara's body mass increasing by the second as her muscles expanded and ripped the new lab coat to pieces. She felt something hard and hot pushing into her stomach and watched in awe as Sara's clit grew upwards from her pussy, splitting open at the tip and forming into a huge, thick, veiny dick.

Kelly's will was almost as weak as Sara's now as she lowered her mouth and took as much of the huge thing into her as she could, making Sara grunt and growl with bliss. It wasn't long after that that Sara had Kelly up onto the counter and filling her pussy with her huge cock, ramming her repeatedly for the next several hours. Beakers and vials crashed to the floor as the girls screamed and grunted in unimaginable sexual pleasure. Kelly was happier than she'd ever been in her life and Sara seemed a little more in control this time as her mind was no longer fighting the things she was doing to Kelly. She wanted her, and now she was hers, her little bitch, her toy, her fuck play thing. Both girls would go on to have sexy many more times, the beast inside Sara never truely sleeping for long, but after several long hours, Sara and Kelly regained just enough will power to get dressed and make their way to Kelly's car.

Kelly began driving Sara home after a long night of fucking. Both girls were exhasted and the drive wasn't that short. Sara had found a few spare clothes to make it to the car in and she just wanted to go home, get a hot shower and go to bed. She gasped as she felt Kelly's hand on her leg, watching it move downwards to her crotch, and then under her pants and into her quivering cunt. Sara gasped and protested but the feeling, the feeling of Kelly's fingers inside her pussy made her moan. Kelly wasn't sure why she was doing this, she was trying to make Sara change, in her car, on the highway, no, she couldn't, she shouldn't, but the feelings flowing through her were not letting her stop, she couldn't stop herself from wanting Sara to grow big again, to grow a huge cock, to put it inside her! Sara felt her muscles already tightening up, her breasts were swelling and her nipples growing into hard points, immediately starting to leak milk. Her cock began to form and grow from inside her folds, pushing Kelly's hand outwards as the jeans she was wearing tried in vain to hold in the massive flesh pouring outwards from her soaking vagina. The zipper broke open and the button snapped off as it grew hotly out into the air, quickly growing several inches in seconds, pushing right up into the dashboard of Kelly's car. Kelly's hand moved up to begin to stroke it, and Sara did her best to lay the seat back as her body began to expand, pulling all of her clothes to their limits quickly. Kelly's hand job made Sara moan, and she tried and tried to stay in control, to not let herself go too far, for if she did, they'd crash in the car and die. Kelly wanted to suck on this cock so bad her mouth was watering, and she quickly made an exit and swung into an abandoned parking lot. No sooner had she put the car in park than she was leaned over and started sucking Sara's hot, veiny cock. Sara came almost instantly from Kelly's hot mouth on her cock, and she came again and again within just a few seconds time, filling Kelly's throat and mouth with copious amounts of hot girl cum. Kelly couldn't get enough of it, it was like food that tasted so delicious that she just couldn't get enough of it. Sara was losing control of her body, the shirt she was wearing tearing almost too much to bother wearing as her tits swelled further and further into it, the milk leaking from her nipples saturating it with wetness, and her jeans were breaking at the seams in the ass and on her hips as they swelled and grew heavy with muscles. But Sara held on to the last second before she finally came extra hard from Kelly's expert blow job, allowing her precious seconds to come down from the bliss and gain some control. Kelly smiled as she drank down the last of Sara's hot cum, got back into her seat and continued on her way to Sara's place.

Sara was so tired now she almost needed to crawl up the stairs to her apartment, but Kelly gave her a helping hand and they got inside her apartment with little trouble. Sara thanked herself that she always kept her loose items, like keys and lipstick in her purse, so it had avoided being shreaded to death with the rest of her clothing. The door shut with a thud and Kelly locked it behind her as she ran up to Sara and began to kiss her deeply, her hand quickly placed into her crotch to fondle her still soaking folds. Sara had to stop, she was already starting to get horny again as her entire body shuddered, and Kelly didn't appear to be slowing down on wanting her to fuck her. She kept Kelly close as she slowly made her way into the bathroom, threw on the cold water in the shower and pulled herself and Kelly right into the frigid water. Kelly yelped in shock as the water soaked her to the bone, and Sara felt a sudden release as the cold water took the heat away from her body for the first time all night. Kelly seemed stunned by what had happened and Sara tried to remain calm even while they stood in subzero degree water, in clothes, shivering. Sara shut the water off and told Kelly she had best leave while she had the chance, as she suspected it was the pheramones she was pumping out that was making Kelly do the things she had been doing. Kelly weakly protested but Sara assured her things would be ok, but until she had a chance to figure out what she'd gone and screwed up with herself, it was probably best for her to be alone, Kelly gave her a quick kiss and agreed that if things did continue the way they had, she'd probably end up dying from the sheer amount of sex, something neither of them wanted to see happen. Kelly asked Sara to call her as soon as she woke up and found out anything, but until then, she agreed to stay away unless she was called to help. Sara asked Kelly to grab a few bits of data from back at the lab, and to clean up the mess they'd made, to hopefully buy her enough time to work things out, to which Kelly agreed would help a lot. They bid their farewells for the evening and Kelly left in her car and made her way home.

Sara had a makeship lab in her apartment that she had been using for some of the more mundane parts of her experiments with the serum, and she was glad she'd been one to work as much at home as at the lab. Hopefully somewhere in her notes or maybe in her blood, was the answer to what had went wrong and hopefully, how she could fix it. But Sara couldn't fight the one thing stronger than her libido now, and that was sleep, she was falling asleep standing up and had to go to bed. The night was a long one and Sara awoke over twelve hours later drenched in sweat, several wet spots dotting the bed. Her body was warm and she was twitching. Sara got the sinking feeling that her inner beast was wanting out soon, but now she was alone, oh Gods no, she hadn't thought of what might happen now, if she lost control, she might go insane with lust or rape anybody she saw on the street. She tried not to think about it and quickly took another cold shower, which seemed to help a lot, and then she got to work in her lab. She took blood samples and got hard to work making notes with the anaylization, finding a definite increase in estrogen and testosterone in her system. What was shocking was that even over the short course of the afternoon as she was checking and rechecking her data, the amounts in her system were steadily increasing, and in fact she suspected her very own cells were producing them on their own. She remembered that the mice and rats had increased libidos during all the preliminary tests, but they had always abated soon after. Sara soon realized what it was, size. Mice and rats weren't very big, the amount of blood and cells in their bodies was nowhere near the concentration inside a human body, and so instead of abating like in the mice and rats, the cells simply bounced the effects to other cells close by, allowing those cells to signal more cells and so on, steadily increasing the serum's effects until her body was mutated into some hyper sex fiend. She thought she had the best of both worlds, the body of a beautiful, yet muscular super model as well as the lasting power of females in general during sex, with the massive phallac mass of a huge cock in which to screw anything she saw as fuckable.

Sara got a migraine as she continued to work, trying in vain several different equations for reversing the effects she had brought upon herself, and after several hours of work, she knew her body was gearing up faster and so she took another cold shower. This time the cold water did very little to help, and after only about a half an hour, her body was sweating badly and she could tell her hair was starting to grow longer. It was happening again and Sara felt so helpless to stop it as she felt her body tensing up, her muscles growing thicker, the veins puffing up on the surface of her skin as her clothes pulled tightly to her body, starting to become soaked in her sweat. Sara wasn't sure what to do as her mind began to wane with logic taking a backseat to instincts. Should she call Kelly before it was too late? What if she didn't make it in time? Gods, Sara was getting scared, and she quickly reached for the phone, but to her dismay, she couldn't remember Kelly's number. Her head was pounding and her crotch began to heat up with more and more lust each passing second and she could feel her clit parting her outter folds as it swelled with her blood and soon her cock would rip from her jeans and then she'd be on the hunt for pussy. Gods, no, Sara thought, trying to stay in control of a beast that she knew she could never beat, at least not for a while, until time had passed and her body had grown accustomed to the changes, maybe then she'd gain some control, if her body didn't explode or breakdown from the increased amounts of estrogen, testosterone and who knows what else that was now causing her to become a lust monster. Sara suddenly heard a few thumps from upstairs and her mind grasped instantly what it was, Alice. Lonely little Alice lived upstairs and was very quiet and very beautiful for being a mother of two grown up kids. Her husband had left her and the kids years ago, and once her kids turned eighteen they went out into the world to find work. She was a good cook and worked at a decent restaraunt down the road from their apartment, but after Sara's quick recap of Alice's life, one thing became crystal clear: she had to fuck her. No, no, NO Sara said to herself, not Alice, Gods help me, not her, she's alone, she'll be terrified, she'll scream, I'll hurt her, I'll, Gods she has suck big tits and an ass that won't stop. I bet she's just been waiting for a big cock like mine to ram her right in the cunt and ride her until the sun comes up! Sara's mind was oozing out of her ears faster than she wanted to admit, and now she had a plan and a mission.

Sara's cock was now growing rapidly from her crotch, straining the zipper on her pants to it's limits as it swelled and buldged hotly inside it's restraints so she wasted little time and getting out into the hallway and rapidly advancing up the stairs to Alice's door. She pounded on it quickly and with purpose, screaming at herself to not do this, to not ruin this poor woman's life, but her beastly side was having none of it, all Sara knew now was that there was a woman in this room that had a vagina with nothing in it, and she would fix that problem shortly. The bolt clanked back as Alice slowly opened the door to see who had beaten it so hard. She barely had a glimpse of the new towering Sara's body before she was shoved backwards from it when Sara gave it a heave ho wide open, slamming it behind her and locking it. Alice gasped as she asked what Sara was doing and what was happening to her, as she easily recognized her face as Sara's but her body was that of Lou Ferrigno not her friend and neighbor. Sara was drooling and staring right at Alice as her cock was released from inside it's fabric prison as the zipper gave way and the button shot forward into Alice's stunned hands. It erected into Alice's view so quickly that she stumbled backwards into the arm of her couch, practically stunned by it's size and girth. Sara made her way quickly to Alice and had little trouble tearing open her shirt, seeing and delighting in the fact that she had no bra on as she began to suckled her nipples expertly. Alice was protesting and kicking for her to stop, but she wasn't screaming as she thought she should, but moaning at Sara's hot mouth on her nipples. In spite of herself, she felt her nipples hardening quickly for Sara, and even her pussy began to become moist, things even Sara's lack of logic could make easy work of, she was ready to fuck.

Sara layed Alice over her couch arm and tore her jeans from her in one quick motion, Alice unable to move from both shock of pleasure and shock of fear as she knew what was coming without even having to guess. However she still begged Sara to stop up until she saw the tears coming from her eyes and heard her grunt to her that she was sorry and couldn't resist, begging her for forgiveness. Any further resistence melted away at that point when she felt Sara's huge cock penetrate her to the hilt, it's massive shaft spreading her vaginal lips apart like a jackhammer through stone. She felt every inch of it sliding in and out of her, and her pussy responded in turn by gripping onto it like she had to repel out of a burning building using only her pussy lips. Sara grunted and moaned, feeling how tight Alice's pussy had become after all these months of sexless nights and the tightness only made it grow even larger and hotter, pushing both of the girls to the limits of conciousness. Hours upon hours ticked by while Sara put Alice in position after position, holding her high in the air, up against the wall, doggy style, frontways and sideways, anything to please her aching urge to fuck. Hours more passed before at last Sara had put forth so much effort that her own beastly mind had taken enough and had to relenquish it's control and allow normal thought to take over. Both girls collapsed, Alice onto her soaked couch, and Sara onto the floor, and neither could speak, either from lack of air or from pure exhastion. Almost half an hour ticked off the clock before Sara sat up and began to beg Alice for forgiveness, explaining everything that had happened. Alice was a down to earth person, and she understood what had happened was accidental, and she also knew that she just had the most wonderful time during sex in her life and told Sara that no matter what else happened, if she needed her, she'd help in any way she could. Sara begged Alice to stay away for fear that she might get hurt, but Alice assured her that whatever Sara had become it wasn't interested in violence and death. Sara felt some relief at last of this dreaded disease she'd cast upon herself, and asked Alice to take a shower as quickly as possible out of fear that her pheromones would start acting on her and this whole thing would start again just like it did with Kelly, and she agreed in the name of science to take the doctor's orders. Sara carefully made her way back downstairs to her own apartment and took a cold shower herself, hoping to cage the beast inside her for a while, long enough to somehow fix what she'd done to herself. She was tired, and wanted to sleep, but she knew the beast would claw it's way out of her during her time asleep, so she convinced herself that she had to stay awake, for the sake of every pussy in the apartment complex.

Sara ran more blood tests, and even spit and cum tests on herself, looking for the pieces to solve her serum puzzle. She knew her estrogen and testosterone levels were going up at a constant rate, but she knew that alone couldn't change her like it did, there was something else she was missing, the unknown element she couldn't pin down. The phone rang, it was Kelly telling her that she'd gotten to the lab and cleaned up their mess, and she had emailed her all the data she had at work on the serum. She asked if she was ok and she told her all about what happened with Alice to which Kelly gasped and begged her to let her help before she lost control again. Sara couldn't risk it, and told her to stay away, but she'd call her if she had to. She hung up the phone and dove into the her email for all the data she'd collected, going over every line of ever forumla, searching and pleading that she'd find the answer. Almost four hours passed and nothing changed, except for Sara's libido, which was already starting to heat her body up. She knew she was already starting to change again, and much faster now, probably due to her body finally absorbing the serum completely into her system, into her very DNA. She had to find the answer and she was running out of time. Sara saw her hair starting to creep down into her eyes, and her breasts began to ache again as they filled steadily with rapid milk production, her nipples hardening and turning purple, starting to throb inside her tightenting shirt. Sara was getting frustrated now, she couldn't get the answers she was wanting and now she was about to lose control again. She got up and ran to the phone, calling Alice who immediately came down to Sara's door. Sara let her in and told her it was happening again, and by the Gods she needed her help, or more specifically to have sex with her. Alice seemed ok with the idea as she saw Sara slowly becoming a muscular mosnter right before her eyes and again Sara asked for forgiveness and even told Alice where she had her gun, already loaded if she got scared or something happened that threatened her life. Alice couldn't dream of killing Sara, she didn't even want that thought in the conversation, but Sara made her promise that no matter what happened she'd keep her away from anybody else. Alice agreed just as she saw Sara's hard cock burst from her panties, already dripping cum from the tip that ripped open at the tip of her clit. The veins pulsated wildly on it's surface and Sara was drooling as she moved toward Alice.

Alice wasted little time taking off her robe, having not a thing at all underneath it, and Sara accepted her bodily sacrifice to her one eyed god monster as she plunged her cock deep into the bowels of her honey pot. The walls were shaking for hours more as inch after hot inch of Sara's cock pounded Alice into hopeless bliss. The fun slowly ended by six in the morning, almost two hours later, and Sara found herself too tired to move and simply fell asleep on the floor covered in gallons of her and Alice's hot cum. She woke almost ten hours later on the couch, covered in a blanket and still quite naked. Alice was nowhere to be seen but Kelly was sitting at the table, going over Sara's notes. Sara got up and stumbled slowly over to her and asked what had happened. Kelly smiled and explained that while she was asleep Alice told her everything when she came over to check up on her, and over the last several hours, a few of the blood tests Kelly had taken from Sara while she was asleep showed positive results to an anti-serum she had designed. There wasn't enough for one full injection yet, not for another four or five hours, but it looked like she could halt the involuntary transformations for sure, and probably reverse the effects if they had some more time. Sara gasped with relief and thanked the Gods that Kelly was just as smart as she knew she was. But thnking even that was turning Sara on already, and she back away, heading for the showers when Kelly stopped her, grabbing her hand gently. Sara turned and saw that under Kelly's lab coat was nothing but bare skin. She saw her erect nipples and could smell her wet pussy from three feet away. Sara tried to shake her head but Kelly was insistent, almost begging as Sara's body began to change again. Her cock grew outwards right into Kelly's awaiting mouth, the feeling of which nearly knocked Sara on her ass, even as it buldged with muscles. Her hair grew wild down her back and ever fiber of muscle in her body expanded outwards to make her grow taller and sexier in every place right to be so. She grunted as she took Kelly's head and began to pump her cock much harder and faster into her mouth, giving herself a blowjob in fast food mode. She came with enough force that Kelly's head was pushed clear off of it, and then sprayed with several gallons of hot cum. Sara's cock didn't even show any signs of going limp as Kelly got off the ground and bent over the couch, teasing Sara to stick it into her. Sara's mind was in no mood to think about teasing anything, and rammed Kelly's pussy to the hilt and began to ride her so hard and fast she started to slide the couch across the floor and into the wall. It was well into the evening before the girls gave out, slumping to the floor as sweat glistened on their bodies and cum oozed from pussy lips and cock, even as it shrank back up inside Sara's own cunt. Kelly heard a ding and sat up, wobbling over to the lab table, finding the first batch of the anti-serum was ready. She prepared it in doctor fashion and brought the seringe over to Sara, who weakly smiled and whispered to Kelly she hoped it worked. Kelly assured her it would and injected her with the full shot she had came up with.

Sara screamed as fire poured through her body, becoming rapidly horny and changing back into her beastial form quicker than ever, even her cock sprang to full attention immediately, growing even larger than Kelly could dream a cock could. But even then, Sara, though out of breath and hot, wasn't overcome with the urges she had before, she felt basically normal. Kelly too, no longer felt the immediate urge to be fucked by Sara and the first blood test showed that Sara's cells had finally stabilized and were now in a two stage shift, one her normal self, and one her muscular cock equipped self. Both girls sighed with relief that the rest of the neighborhood was finally out of danger of becoming a victim of the Night Fucker. The girls giggled and took a shower together, Kelly giving Sara a nice blowjob and Sara giving Kelly a nice hard fuck before she willed herself back to normal and they went out for a nice night for dinner. In the weeks that followed, Sara found her small problem and corrected it, finding that her newest serum allowed women to each bring out their inner beast, and control it however, and whenever they desired. Of course only two other women besides Sara would receive the gift of Goddesshood, but then again, they did cancel her project so the company's loss was their gain.

The End
