The Grass Isn't Always Greener
"So all I have to do is take a pill once a day?" Zero asked, peering at the tiny white tablet in his pale hand. Hardly seemed like an experiment at all; taking a pill... being monitored. He had been hoping this experiment would be a little more exciting than that.
"That's correct," the doctor sat with her legs smartly crossed, looking down at her clipboard; flipping through pages. Her hand reached up to brush her auburn hair behind her ear. "We want to monitor the changes in your behavior and appearance, if any actually occur. You'll be able to socialize with other test subjects, since keeping you all separate would ruin the point of this experiment, so you shouldn't be too bored for the three weeks that you're here. Once the initial testing period is over you'll be allowed to go home and return to your daily routine as long as no adverse affects have been noted." Her tone was highly detached as her green eyes darted back and forth across the paper, the pen in her hand scribbling things here and there; finalizing Zero's paper work.
He snorted. This was going to be a waste of time.
"Well, if you don't have any further questions go ahead and take that. Then I'll show you to your accommodations." The doctor said. She watched with more detached apathy as Zero drank from the plastic cup he held in his other hand, and then pushed the little pill past his lips. He hardly felt the pill slide down his throat as he swallowed the liquid, though he did notice a slight aftertaste.
"Right then. Please follow me." The doctor said as she rose from the stool she had been sitting on and walked to the door. Zero got up from the chair he had been sitting in and followed her out of the hospital room. She stopped at the nurse's station, handing the girl sitting there the completed papers and exchanging pleasantries before turning and motioning towards the elevators. Her delicate fingers pushed the down arrow on the wall. The lights over the doors on Zero's right lit up, and a ding sounded as the metal doors slid open.
The doctor walked into the spacious cart, pushing the button labeled B'. No sunlight for three weeks, Zero wondered as the doors closed behind him. They rode down the three stories of the building in silence, the only sound the whoosh of the circulating air. The elevator lurched to a stop, and the ding sounded again as the doors opened to the basement floor of the building.
They exited the elevator into a while hall with nearly blinding florescent lighting. The halls were lined with closed doors spaced out at even intervals. The doctor turned to the right, her white lab coat billowing out behind her as she walked.
"This way. Your room is going to be B142. We just finished filing up the rooms in the other corridor so there aren't many people on this hall yet. I believe the only other person on this side so far is a young woman named Ruby. This entire floor is sectioned off for this experiment so feel free to wonder where ever you want. The elevators are locked once all medical personal leave the floor so you'll be unable to go to other floors without someone escorting you there, but you shouldn't need to go anywhere else. Everything you will need will be provided for you. All you need to do is ask for it if it's not already here," The doctor explained as she walked down the hallway, her heels making tap tap tap sounds on the un-scuffed floor.
"Here we are. This is your room for the upcoming weeks." The doctor pushed the door open and stood to one side so Zero could walk into the room at the very end of the hall.
The room was on the small side, with very little in it. There was a decent sized bed pushed into the back corner with two pillows on top of it and a dresser with a mirror on the opposite wall. Beside the bed was a plain night stand. There was no alarm clock, no lamp, no phone.
"Clothing has been provided for you as part of the test. Everything should fit, if not let us know and we'll take care of it. Bathrooms are around this corner and about halfway down the hall on the right. The dining area and common room are right across from them on the left. I find that subjects adjust better when left to their own devices as far as being introduced to the rest of the group, so I'll leave you here.
"A technician comes down two to three times a day so if you have any concerns those would be the times to say something. I'll be down tomorrow to assure that you've settled in ok," and with that the doctor turned and headed back toward the elevator, leaving Zero standing alone in the small room that was to be his new home.
Morbidly curious about the clothing the doctor mentioned, Zero turned to the dresser. There was no way he was going to like what they picked for him, he was sure. His brow furrowed in confusion as he looked down at the garments supposedly left for him to wear. Surely the doctor had taken him to the wrong room, or maybe it was some part of the experiment, to see how he would react to something this absurd.
There in the top drawer lay a pair for soft pink underwear and a matching bra; a delicate flower pattern barely visible, stitched in a lighter shade of pink. Before he could register what he was doing his fingers gently brushed against the cups of the bra. The material was so soft under his finger tips. Guiltily he pulled his hand back and quickly closed the drawer, ignoring the discomfort in his jeans. That's just what he needed, for a bunch of doctors to think he was some sick freak that wanted to wear girly pink panties.
He went to the door and looked down the hall, hoping to catch the doctor before she left. This couldn't be his room, but the hall was empty. Growling, he shut the door a little more roughly than needed and half laid half fell onto his bed, closing his eyes in an effort to block out his thoughts. He would just have to talk to one of the techs whenever they came down here and let them know of the mix up.
He laid for several minutes on his stomach, trying to keep his mind empty. He couldn't seem to keep the images of those two pink garments from popping into his head though; the feeling of the soft cloth against the skin of his fingertips a guilty pleasure he couldn't erase from his mind. What would the cloth feel like rubbing against his hardened nipples? What would he look like, strutting around like a tramp in them? He rolled onto his side, trying to ease the ache in his cock. His index finger moved to trace circles around his already stiff nipples through the fabric of his t-shirt. What would it be like to have breasts to be toyed with through those cups? And a wet little pussy to be fingered through those girly panties?
Zero groaned as his cock jerked. He could see himself standing there, someone's sexy little play thing, all wet and ready to be used. Too caught up in his fantasy to truly realize what he was doing Zero got up from the bed and walked back to the dresser.
He shivered in anticipation as the pink material slowly came into view again. His hand moved to trace the cup of the bra while his other hand mimicked the movement on his own chest; one hand softly gliding over the garment where he could picture a stiff nipple denting the material while the other hand caressing his chest. He toyed with that sweet spot on the bra, teasing his own nipple at the same time, sending jolts of sensation rushing down his spine. Roughly, he pinched the material of the bra, following suit to his own nipple, squeezing the hard tip between his fingers. Zero whimpered, biting his lip as his cock jerked again; precum already oozing from the tip of his stiff member.
Self consciously he looked over his shoulder, as if someone could be hiding in the corners of his room; watching him fantasize about being a slutty, horny girl. There could be cameras set up to monitor him; they could be watching right now. They could be gathered around a computer screen at this very moment, watching the bulge in his pants grow while he stood teasing himself like a harlot.
They? What was he thinking about? Who was supposed to be watching? And why? Zero frowned. No one was watching him. Why would there be cameras in his room anyway?
He turned back to the dresser, the pink lingerie filling his vision. Something was wrong; there was something he was supposed to remember... Something important... something about those sexy pieces of clothing that sitting there taunting him...
What was wrong with him? Of course there wasn't anything to remember. Those panties were his; he had bought them himself. Zero shook his head, trying to clear it. Why was he acting so weird?
Quickly Zero took his shirt off, tossing it onto the floor, pushing all other thoughts from his mind. He picked up the bra, holding it in front of his body before slipping his arms through the delicate looking straps. His whole body shuddered as he fastened the clasp behind his back, encasing his chest in the soft cups.
He filled the small cups perfectly. His body was smooth and feminine looking already. Wearing the dainty bra only added to the illusion that he' could actually be a she'. His hands traced his skin upward from his hips to the bra, groping himself through the fabric. God, he looked like whore standing there touching himself.
Breathing slightly harder, Zero moved his hands back downward to the top of his pants. Slowly, as if doing a strip tease, he pushed the jeans to the floor; his erect cock sticking out, eager for attention. He ignored the throbbing in his groin however, and reached for the panties, anxious to see what he would look like in them. He groaned as they slid up his calves and thighs, hugging his cock against his body as he pulled the waistband up to just below his navel.
The mirror's reflection was almost enough to make him cum. The delicate panties looked so sexy; if only he had a pussy; a tight, hungry, wet little pussy to rub off. Zero slowly ran his hand down the front of the panties, teasing his cock. God it felt so good through the soft fabric. He stepped back until the back of his legs bumped against the bed, then he sat, watching his reflection in the mirror as he spread his legs wide, still running his hand up and down the outside of the panties.
Zero couldn't help it; it was just so fucking hot. He looked so fucking sexy; so slutty sitting there rubbing himself off as if he were really a girl. His precum was soaking the front of the thin panties, making them wet underneath his hand; the feeling of the soaked fabric only adding to his fantasy. If only he had a pussy he thought, his hand rubbing harder and harder against the panties; small moans escaping past his lips.
Closing his eyes, Zero leaned back, lying down on the bed. God, he could totally see himself becoming a chick. He could see his cock being replaced by a slutty pussy; one that was always wet and ready to fuck. A pussy that always ached to be filled with a throbbing shaft; a huge cock, one that would push against his cervix with every long, hard thrust. He could see himself with a sexy little clit; pierced with a shiny, silver ring that people could tug on. Oh, and how he would cry out and moan when they did that; it would be almost like an automatic cum button. All anyone would have to do is give it a little attention and he would turn into a total whore, cumming all over their hand or face like a bitch in heat. And his breasts! He could see them, big and round. DD sized tits rocking back and forth while he was roughly fucked. God, and his nipples would be pierced, just like a dirty slut. MMmmm, and his tongue too. He couldn't be a real slut without a tongue piercing. He could just imagine what it would be like to run a pierced tongue up and down a cock as it cam all over his face, pumping out massive loads of spooge until it oozed down onto his heaving tits where he would smear it into his skin like a filthy, dirty whore.
Zero was so absorbed in his fantasy that he failed to notice that it wasn't just a fantasy anymore. His balls and cock were slowing being drawn into his body, as if rubbing them were pushing them back into his skin. Rub after rub erasing his manhood, bringing him closer to not only his orgasm, but closer to his dream of being a slut. His crotch became flatter until the giant bulge that had been his cock was completely gone; the area between his thighs as smooth as if he had never been a male at all.
Oblivious, his hand continued to rub; his mind not registering the changes happening to his body. His other hand reached up to squeeze his tits. They swelled under his grasping hand, pushing out the fabric of the bra until the garment couldn't stretch any further. His tits were so big and sensitive, his nipples ached for attention. He mauled his breasts, gripping and squeezing them through the bra while the skin between his legs pulled apart into two wet, slippery folds. The ache that had been centered in the head of his cock split in two. Half of the ache seated itself at the top of his new pussy, forming into the sexy, slutty clit he was fantasizing about. The other half inverted itself, becoming a weight in his body that slowly bore a hole into his new sex. The panties that had been soaked with precum only moments before were now being soiled with sticky lube as it leaked from his pussy.
Zero moaned loudly as his relentless fingers took on a mind of their own, pushing the material between his pussy lips, right up against his new hole. His hips arched upward each time he brushed against his clit; undulating as if he was fucking an imaginary cock. If only there was a cock that could fill him up right now; a big, thick, cock to feed his tight, hungry pussy. He could feel his new muscles contracting around the emptiness. He was so empty inside, so vacant and unused. It should be a crime! His slutty little pussy shouldn't be made to weep so much in frustration he thought, groaning as his muscles clenched down again. There should be an endless line of stiff pricks waiting to get inside of him. He should have three of them at a time, all of his holes being filled, and then another two should be thrusting in and out of his hands while his body bounced up and down, his mouth moving back and forth. There should be cocks everywhere; every day all the time. He should be a slutty fuck toy. That's what he was good for, what his pussy was made for; to please cock after cock until he passed out, unable to suck or fuck any more.
The images in Zero's mind were so vivid that he screamed as his first orgasm as a women crashed through his body. It was so intense; almost painfully so. Over and over he cried out as his cunt contracted, his hips thrusting upward uncontrollably against his hand which was grinding insistently against his slit; his other hand squeezing his breast to the point where bruises were sure to form. He thrashed for several minutes, fem cum gushing out from his cunt and soaking the bedding underneath him.
It took several minutes for him to recover from the orgasm. He panted and gasped, trying to remember how to breathe normally while aftershocks sparked through his nervous system. Sweat glistened on his skin, raising goose bumps as it cooled his overly sensitive body. The sticky wetness of cum dripped down his calves which still hung over the side of the bed. He felt so weak, so drained of energy. He could hardly believe how awesome his body felt. It truly did feel like he was floating on a cloud, drifting slowly back down to his body.
Struggling against his tiredness, Zero pushed himself up so he could look down at the mess he had made. That's when he realized that it hadn't been a crazy vivid fantasy at all. Large breasts heaved with his labored breaths, jiggling slightly. And between his legs the panties still clung to his leaking pussy, outlining the lips of it perfectly.
"Oh my god!" Zero gasped out. What had happened to him? How had this happened?
"Well you didn't take long at all. I'm almost disappointed. All of the other subjects put on a much longer display than you," terrified by the unexpected voice, Zero looked to the now open doorway. The doctor stood watching him with a smirk, though he couldn't recall having ever seen her before. To Zero she was just a stranger in a white lab coat, holding a collar and a length of chain in her hands.
"But then I guess I should have known you would be a fast one; dirty slut that you are."
"What happened to me?" Zero asked in a panicked voice. Shocked, he raised a hand to his throat; long, sticky stings of fem cum dripping from his fingers. As if becoming a girl wasn't screwy enough, he even sounded like a girl now. Confusion and panic turned to anger. What the hell was going on?!
"Look at me! I'm a fucking girl! What the fuck is going on?!"
"Mmm, I'm looking at you alright. And all I see is a slutty bitch covered in her own cum. And naughty little sluts like you need to be punished. You are naughty aren't you?" The doctor asked as she pushed away from the doorway, slowly walking toward Zero, her shoes sounding out each step on the floor
; the chain clanking softly as it swayed in her fingers. She stood between Zero's spread legs and leaned down, bringing her face level with his. "I bet if I touched your pussy right now you would cum again," she all but whispered against his ear.
Before he could react the doctor grabbed a fist full of his hair, pulling his head back harshly until he was lying on the bed again. The doctor crawled onto the bed between Zero's thighs, setting the collar and leash down, pushing them further apart.
Zero couldn't help moaning at the feeling of his legs being spread. It felt so dirty; so hot. He was terrified by the way his body was betraying him, how he was becoming aroused all over again even though he didn't want the doctor to touch him.
"Please don't," he whimpered quietly as the doctor's small hand cupped his breast, just as his hands had done only minutes before. The feeling of another person caressing him caused his back to arch; pushing the flesh more firmly into the unwanted touch.
"See? You're a slut. You can't help wanting it. Needing it," The doctor trailed her finger tips down from his chest, grazing her nails down his flat stomach to the waistband of the panties. "You want me to touch you now, don't you? You want to beg me to get you off."
"Yesss! Please. Please make me cum," All that mattered was the burning between his parted thighs. His hips were thrusting into the air again, trying to find something to rub his pussy against. His hands gripped the bed covers and his head tossed back and forth despite the hand still yanking his hair down. "Touch my clit. Please, just one touch I swear. Anything, I'll do anything, just touch it please. Lick it, stroke it with you're hot tongue. Please, anything, everything. Just make me cum!"
"I'll make you cum if you follow me. How's that? Sound like a fair deal? I'll make you cum over and over you bitch. You'll pass out before I'm through with you."
"I'll do anything. I promise," Zero begged.
"Come here then," The doctor said, grabbing the leash and collar before easing off of the bed and walking backward towards the doorway. Zero shakily got to his feet, wobbling on his still weak legs. Before he was able to take more than three steps however, he heard the woman's disproving voice.
"Ah ah ah... dirty sluts like you have to crawl everywhere. You don't get to walk like a human any more. You get to walk like a horny bitch."
Zero could hardly believe his ears. She couldn't be serious, could she?
"Do it or I'll leave you here alone, all hot and bothered. Alone with no one to make you cum," a wicked grin spread across her face.
Whimpering at the thought of being alone Zero sank down to his hands and knees. Tentatively he moved forward, moving slowly incase the woman should find fault in his actions again. When his movement didn't earn him a reprimand Zero moved faster, crawling until he was kneeling in front of the woman.
"Mmm, good girl," she cooed.
He was shocked for a moment. This whole time he had been thinking of himself as a man still, but in truth he was a girl now. Zero the slut; Zero the filthy whore. The realization made his pussy clench. For all he had fantasized about become a female, he had never actually thought of himself as a her'.
"That's right. You're a sexy bitch now aren't you? No more cock, just a wet pussy that wants to be fucked." The crude words were like a drug for Zero, altering the way he thought. He was no longer a he; he was a she, and she did desperately want to be fucked.
"Please," she begged, looking up at the woman in the lab coat. "You promised to make me cum," she whimpered.
"Oh and I will pet," the woman replied, crouching down in front of Zero. The collar was fastened around her slender neck, the chain already attached to the metal loop of the collar. As the doctor stood she yanked the chain roughly so that the leather of the collar bit into Zero's skin slightly, pulling her forward.
"Don't fall too far behind pet, else I might have to punish you," the threat was enough to motivate Zero. She crawled quickly to keep up with the woman holding her leash, wanting more than anything to please her. She was anticipating her promised orgasms so much that she was leaving a trail of clear, sticky wetness on the otherwise spotless floor.
She didn't pay attention to where they were going. It didn't matter to Zero. She kept her eyes on the floor, watching the tiles as they passed one by one, cold beneath her palms, marking her progress down the overly bright hall. All that mattered was the aching in her pussy unused.
"Right in here pet. Go in there and you'll never stop cumming," the doctor said, pushing open one of the double doors that suddenly appeared in front of Zero.
Cum. The word filled her mind as she crawled through the doorway. That's all she cared about, finding a way to cum again. She couldn't remember caring about anything else, of there ever having been anything but this unbearable sexual hunger between her legs.
"Just a little further. You need to get in your cage. Sluts have to be locked up, and taken out only when someone wants to play with them," the woman gently tugged the leash towards what looked like a metal pen towards the back of the room. In front of the pen cage was a clear shower stall, like a giant vertical aquarium almost. A tube ran from a milking machine near the pen to the top of the tank, where it was attached to what appeared to be a shower head. Inside the stall, crouched in trembling ball, was a young man. His skin was flushed as if he had a fever. Zero could see sweat rolling down his arms and back. The smell of his arousal was thick on the air, like a musky perfume. Her mouth watered as the woman swung the door to the pen stall open, ushering Zero into the metal cage. The doctor followed her into the pen, attaching the leash to a metal hook in the pen so that Zero was facing the male.
"Ruby can smell you," The woman said. "He's so horny right now I'm surprised he's not cumming everywhere from just the scent of your pussy. But he had fairly good control when he was a girl too. It took so much to push her over the edge, but once she reached her breaking point there was no way for her to stop. Oh yes, the person in that tank use to be a sweet, timid girl. Now he's a horn-dog. He's had a hard-on ever since his transformation. No matter how often he cums his prick just won't go down," the woman explained as she knelt behind Zero.
"Ruby's an awfully nasty dog," she continued. Zero whimpered as she felt hands stroke her hips like an animal.
"Wouldn't he make a sexy dog?" Zero watched as the male shuddered, covering his ears in an effort to block out the woman's voice.
"Can't you see him with perky ears on his head, and a doggy muzzle with a long tongue that would hang out as he panted. " The man let out a strangled sound, almost like a mix of a suppressed moan and strangled cry. He shook his head back and forth furiously, denying the words that were obviously having some effect on him.
"Watch," the woman whispered, stroking Zero's face.
Across from them, the male shuddered violently, falling out of his crouched position against the glass to his hands and knees, his head hanging down close to the floor. Zero whined at the sight of Ruby's massive cock, hard and ready. Her attention didn't stay there long however. The male let out another strangled cry of agony as he collapsed onto his stomach, his arms seeming to have given out from under his body. Zero frowned in confusion as she noticed two lumps poking out of the man's dark brown hair. Those hadn't been there before surely. Her confusion gave way to revulsion as Zero saw the man's jaw slowly change, lengthening and sprouting a thin layer of fur. He was actually changing into a dog! She was too shocked to do anything but kneel with the doctor petting her body, watching the horrible scene taking place behind the glass.
Ruby rolled onto his back, cock still hard despite the look of pain on his face. His hands shook as he reached into his hair, running his fingers over the now fully grown pair of pointy dog ears on the top of his scalp. Slowly his hands ran down his head and along his new muzzle. Zero's eyes widened as a huge glob of pre-cum oozed from the head of his cock. Was he actually aroused by what was happening?
As if answering her question, Ruby groaned, gripped his cock in one hand while the other continued to play with his new ears and jaw, his tongue lolling out to the side. He slowly started jerking his fist up and down, his hips thrusting up slightly each time his hand reached the base of his cock. More pre-cum leaked from his cock tip causing his hand to make messy, wet sounds as it moved up and down his length; making it glisten with his own wetness.
"He's so bad, look how horny he's getting by being changed into an animal; a stupid horny dog, a total slave to his baser instincts. I bet he wants his body covered in soft, silky fur. Some crazy color fur so he stands out from the other dogs; and a fluffy tail wagging behind him, too. Can you imagine what it would be like if he had paws? He'd have clumsy paws that could barely wrap around his cock. I'm sure that would be frustrating; being so horny all the time, but unable to get yourself off," the woman cooed as her hands reached under Zero to tweak her nipples.
She whimpered, pushing her hips back against the woman behind her as black and bright purple fur flowed like water over the male's skin. It started from his hairline, flowing over his face, filling out the scruffy peach fuzz that had been there before. The fur moved down his chest and arms, the muscle structure changing as his new fur coat grew from his pores. The bones in his hands visibly twisted, reshaping themselves into the very paws the woman had just described.
Ruby whined like an abandoned puppy when it became clear that he would no longer be able to stroke his own cock. No matter how he tried he was unable to get his short stubby paw fingers around his dick.
"Aww, what's wrong Ruby?" the woman asked in a teasing voice, her hands still groping Zero's breasts. She was almost delirious from the teasing. Her pussy needed a cock so bad; there was already a puddle between her legs, she was leaking so much in anticipation. She watched through half focused eyes as Ruby got to his knees, cock jutting out from his body, and pressed his paws to the glass, hoping his tormenter would give him relief; sad blue collie puppy eyes begging for mercy.
"Come on, Ruby. Show me that sexy tail or yours. You can't be a real dog without a fluffy tail," the doctor chided.
The mixed look of painful pleasure crossed Ruby's face again. His paws left the glass, reaching behind his body to the small of his back. His ears lay flat against his head, his chest rising and falling faster and his breathing sped up. Slowly Zero saw the tip of a purple and black tail rise up from behind Ruby, trembling just like the rest of his body. As it grew longer he pulled it around the front of his body, wrapping it around to his chest. His paws stroked it like another cock, and from the growing look of pleasure on his face, Zero imagined it must be just as arousing. Precum continued to well from his cock, dripping down onto the floor of the tank, creating a puddle to match Zero's own.
"Oh... we almost forgot about his cock. I'm sure he wants that to change into a giant doggy cock, tapered at the tip with a huge knot at the base of it. Mmm, bright red doggy cock. That's what you want isn't it Ruby; the final thing you need isn't it? "
Ruby tossed his head back; eyes squeezed shut, ears lying flatter. Right before Zero's eyes his cock changed from that of a man to one of a dog; the knot at the base of his member enormous. Ruby gasped, caught up in the sensation of his transformation. His head fell forward, eyes opening to take in the sight of his cock changing forms; changing species. His body convulsed as he howled, cum erupting from his new red dog cock. The powerful shots of his release hit the glass of the tank in thick gooey jets, as if his cock were trying to paint the clear walls white with spooge. His gasped, howled, and whimpered as his balls unleashed what seemed like gallons of his fluid; enough to cover the entire floor of the tank in an inch of his cum. His cock twitched and jerked with each squirt, bobbing up and down over and over.
Ruby knelt with his head against the glass, his face high enough to avoid the messier areas, his shoulders rising and falling with each labored breath. His member remained ridged, cum still oozing out slowly from the tip, occasionally jerking. Zero could hardly keep still she was so aroused by the transformation. She was unconsciously thrusting back against the woman's hips, picturing the shaft in front of her exploding like that inside of her, filling her with so much cum that her flat stomach bulged out.
"See what I mean? He never gets soft. All he cares about anymore is humping his cock against something. You two would make a loving pair. Neither of you would stop for hours, would you?" The woman asked, her soft hands still stroking Zero's hot body.
"You wouldn't be a very good bitch though. You're too greedy to be a dog. Dogs want to serve and please. You just want to take. More like a heifer than a bitch. Mmm, you would make a sexy cow too, wouldn't you? Cute little tail swishing back and forth, right here," the woman said, rubbing the area right above Zero's crack. A tingling sensation began at the small of her back. Zero could feel her skin stretching and the bones in her spin pushing out, extending from her body. She understood the faces Ruby had made now. Why he had looked so aroused and in pain at the same time. The feeling of the tail forming was the worst feeling she had ever experienced; the feeling of her very bone structure changing made her stomach turn. At the same time it felt incredible; like an orgasm becoming a tangible part of her body. Her ass swelled as the tail lengthened, pushing against the thin fabric of the panties until the cloth cut into her skin. Bigger and bigger her body bloated straining the material until with a wet, ripping sound it shredded into several pieces, falling to the lube covered floor.
"Mmm, you need a cow face to go with the tail," the woman mused as she rubbed the top of Zero's new tail, causing the transforming cow girl to raise her ass high while her head lowered to the ground. Pain and pleasure collided underneath the skin of her face. Overwhelmed by the overload of sensation, Zero's arms gave out, her hands covering the side of her face that wasn't pressed against the wet tiles of the floor.
Before the bones in her face had stopped shifting, the pleasure/pain invaded her arms and legs. Their shape shifting and changing, more pain than pleasure now, but still insanely arousing. Her joints shifted pulling and twisting the ligaments in unnatural ways, changing the way her arms and legs bent. Her fingers fused together before her eyes, the skin darkening to black, then hardening, the bones smooshing in on themselves until she was left with hooves instead of hands. She could feel the same change happening in her feet, the toes melding into one, the bones merging into a cow hoof. Her chest grew as well, her body mass doubling in size, destroying the bra in the process. The tits she had fantasized about being absorbed back into her body and it bloated outward.
Zero was disgusted with herself. Even through the horror of her transformation her needy pussy still leaked everywhere, still pushed back against the woman seeking a cock to fuck, clenching uncontrollably. She turned her head against the lube slick floor in shame, trying to hide her face as a bestial sound tried to claw its way from her throat. It felt so natural, this sound she wanted to make, so right, so undeniable right.
"That's it Zero. Smear your face in your own juices, slut. You're not allowed to cum yet though, no matter how much you try to hump me. You still need an udder. A dirt udder, since you're so filthy. A nasty, distrusting sludge sack, right here," hands groped her stomach, pinching the skin and pulling down.
She mooed against the floor, giving in to her need to vocalize her pleasure in that way. The feeling of her skin stretching down towards the floor, teats forming where the woman pinched and pulled, the feeling of filling up, bloating out made her moo again, long and loud. Her pussy clenched tight again, harder than when she had cam earlier; painfully tight. Her ass contracted too, both her holes squeezed almost shut. Zero grunted, grinding her teeth against the feeling of her holes squeezing tighter and tighter, drawing closer and closer together; then suddenly there was only one ache, though it felt like her pussy and asshole at the same time. Surprise made her eyes open wide.
"You are a nasty cow. Look at what you did to yourself. Filth udder and shitpussy, so disgusting," warm, wet fingers pushed against Zero's new combined hole. "Even your wetness is filth now."
Humiliated, Zero mooed, humping back against the fingers that were teasing her. She could smell the change in her own scent. It was no longer musky, like a normal girl's. Now it literally smelled like shit. How could she like this? She was a fucking cow now, and still all she could think about was her pussy, which wasn't even really a pussy anymore; it was just a disgusting hole now. Big tears slide down her face as she moaned a pitiful moo.
"Now the real fun can start," the doctor said as she stood up. The front of her lab coat and skirt were soaked with Zero's juices; globes of it hanging off of her clothing in sticky strings. She walked over to the device attached to the rubber hose, being careful not to slip on the wet floor as she brought the device to Zero's side.
"Ruby wants to get dirty. Ruby wants to be a filthy, mucky dog for you," she said in a wicked voice, glancing over to the tank where the dogman knelt in his own cum, furiously trying to paw off again. Watching Zero's transformation had driven Ruby back into a sexual frenzy. His lack of hands was making it impossible to do anything more than torture his cock further though.
The woman eased the milking machine under Zero. Gently her hands gripped each of teats and guided them into the clear tubes until all four of them were secure within the device. She patted Zero's side in reassurance before pressing a button on the machine. The sudden suction on her udder teats made Zero bleat out a moo of surprise. It quickly changed to long drawn out moos of pleasure; her way of moaning now. The milking machine sucked on her appendages, drawing out the filth inside of Zero's udder so the clear tubes were stained brownish black from her manure like sludge.
Her udder muck was sucked through the rubber hose, making it jump and twitch as the contents were pulled through the tube to the top of Ruby's tank. Zero's waste dripped from the shower head at first, individual drops splattering down onto the cum-covered floor and Ruby's duel colored fur sporadically. As the machine continued to milk her teats the flow became more constant until Ruby was literally being showered in shit. He whined, looking pleadingly at the doctor, who stood to the side with a clip board in her hand, pencil moving across the paper rapidly; as if begging her to make the disgusting bath stop while he still continued to try to rub his cock off. Even as his fur and cock became covered in the slimy waste from Zero's udder he kept trying to make himself cum, too far gone to care that the once cum coated floor was now completely brown as the contents spewing from the shower head rained down on him with no place for the muck to drain to.
The level of filth rose as Zero mooed in ecstasy, slowly claiming up his legs inch by inch, reaching up to his balls; the bass of his cock; going higher and higher with no sign of ever stopping. Even the thought of drowning in the smelly, disgusting shit wasn't enough to make Ruby stop trying to grasp his cock. Udder shit dripped from his ears and muzzle as he whined and whimpered trying to find his release.
Zero couldn't believe she was getting off to watching the poor dogman getting covered in her crap. He was totally brown now, covered head to paw, and still his hard-on oozed precum everywhere, pulsing and throbbing in front of his body. The constant suction of the machine was bringing her closer and closer to her own climax. It was as if each teat were a cock in continuous orgasm as the device pulled the contents of her udder from her body. Suck after suck drawing more and more from her, so much that it had submerged almost all of Ruby's huge doggy cock.
"I think that's enough of that. Don't you think?" the doctor walked back over to Zero, pushing the button to turn the machine off. Her teats were swollen and red as the woman pulled them from the tubes, muck still leaking out of them, dripping onto the floor like a broken faucet. Zero mooed in protest as the source of her pleasure was removed from her udder. With the absence of the suction to distract her, she became painfully aware of her aching pussy again. Through the whole ordeal it had been leaking out its new muck lube in just as much excess as before so that her entire back half was covered in slimy gooey shitlube all the way down to her hooves, her tail flagged high to the side, exposing the source of the nasty fluid for the whole world to see.
"You've been such a good girl," the doctor said as she placed the machine back against the side of the pen. "I guess it's time that I kept my end of the promise. I bet you wish Ruby were over here right now with that huge prick of his. You're nasty little slut pussy is just begging to be used. And Ruby would use it alright. His dirty prick would make him keep going until his hips couldn't thrust anymore. You want Ruby to come over here and use you?" she asked in a cooing voice, petting Zero's face.
"That could be your reward for being such a good little cow slut. I'll let you have some fun with Ruby since you're such a well behaved slutty shitcow." Turning she opened the gate to the pen, leaving it open as she walked the short distance to the tank where Ruby was still trapped, half submerged in filth, cock still throbbing between his paws.
Her hands reached up on the side of the tank, undoing a latch Zero hadn't noticed before. The weight of the sludge trapped behind the glass pushed the door open slightly, so that it oozed out of the side of it; dripping down the side of the tank in a small river. The doctor reached down to the other latch at the bottom of the door, standing to the side of the tank. As it came undone the muck blasted the door open so that it spilled out onto the floor in a small waterfall, pulling Ruby out of the tank with it, dragging him halfway across the room with its momentum.
He lay dazed for a moment, then looked up at Zero; the gate to her pen wide open still. Something primal flashed through his eyes before he leapt at Zero, closing the small distance between them so fast he was a brown blur to her eyes. One moment he was sprawled on the shit covered floor in front of her, the next he was pounding his huge cock into her tight cunt. Loud moos tore from her throat at the feeling of being roughly violated. Ruby's thrusting was unmerciful as his hips made slapping sounds against Zero's wet ass, muck splattering between their bodies; being smeared everywhere.
It wasn't enough for Ruby though. His cock had ached for so long. His whole body ached, as if his whole body were a cock He needed more, much more. Growling he removed his cock from Zero, replacing it with his paw, easily thrusting up to his elbow. Zero continued to moo and thrust her ass back against Ruby, too glad to have something inside her body to care what it was. As long as she wasn't empty it didn't matter.
Before long Ruby added his other paw, thrusting both of them in and out of Zero, going deeper each time, until he was up to his shoulders in her cunt, his chest pressing against her hips, and still it wasn't enough for Ruby. Slowly he moved his arms apart inside of Zero, spreading her pussy open so wide that it was like a giant cavern. He could see inside of her body, shitlube making the sides of her pussy slick and wet. Growling again he shoved his head and shoulders into her body.
Zero mooed stamping her hooves at the sudden feeling of fullness. Even as she bucked her hips and swished her tail she could feel Ruby crawling further into her body, he was already up to his waist inside of her, his legs and tail the only parts of his body hanging out. The rest was inside her womb, pushing against her sides, making her stomach bulge out as he dragged himself still further inside.
It was so dark and warm. Ruby knelt, pulling the last inches of his legs up inside of Zero. He was totally surrounded by her pussy, and it felt so fucking wonderful. He lay flat on his stomach inside of her, so that his cock was pressed against the slimy walls of her cunt and began to thrust. Each movement of his hips pressing his cock head against her shitudder, making it spew more of its filth. It gushed out of all four of Zero's teats, causing her to toss her head in bestial delight, mooing so loud it could almost be called a scream.
Ruby kept fucking his cock against her walls, his movement making shitlube pour out of her backside, running down her legs in rivulets, while more of it was forced from her udder. He was vaguely aware of a change in sensation again; much like when he had been turned into a dog. This time there was no pain though; just the feeling of becoming bodiless. He could feel all of the shit around him as if it were part of him. He could feel himself being spewed through the teats of Zero's udder, and pushed out of her ass. He was becoming her shit, a living pile of muck deep in her womb; transforming into disgusting cow manure.
The thought was so disgusting, so vulgar, that he blocked it from his mind. The only thing that mattered was cumming. He had to cum; spray his seed everywhere, gallons of it painting Zero's insides. He ignored the pulling feeling of the holes, pulling himself into a tight ball in her womb. Lube stopped leaking out of her rear hole, and her teats stopped gushing muck everywhere. Instead Zero's stomach started to swell and bulge outward as Ruby kept himself inside of her womb, bloating her body with himself.
He was so close to cumming, and so was she. He could feel her muscles rippling against his body, if you can call being a mass of filth being a body. His whole form ached like a cock, yearned for a climax like a cock. He thrust himself outward in all directions, avoiding the holes so as not to leak out of Zero's body. Her stomach visibly pulsed as Ruby resumed this thrusting, going in all directions now, pushing against everything he could touch.
Zero mooed over and over. She felt like cumming and crapping at the same time. Either release would have felt the same; mind-blowingly awesome. She couldn't seem to reach her peak though. It was almost like being constipated, knowing that it was there and so close, but unable to obtain what would make her feel better. Ruby pushed further, making Zero swell to the point where she was laying on her stomach as if she were a giant balloon, her hooves no longer able to reach the floor, and still he pushed and swelled further, concerned only with his own orgasm.
He was so close. Pushing just a litter further, rubbing against her walls a little more. So unbearably fucking close.
Like a tidal wave, the orgasm and had been so unattainable, crashed through Ruby's form, making him literally explode from Zero's body. He spewed from her cunt like water from a fire hose, nasty blackish brown watery manure, splattering against the back wall. He was expelled through her udder too, going out through all four teats with so much force that he splashed off of the floor and back onto the underside of Zero's body. He found the openings for her faces as well, oozing out of her nose, ears, even her eyes like dirty tears though they were tightly shut; filthy muck running down her face. He gushed from her mouth as well, a stream of brown vomit, making Zero chock, blocking out her moans and moos and grunts that would express the most repulsive and vile orgasm she was experiencing.
The exodus of Ruby from her body was so incredible; so debased. He was violating all of her holes at once so forcefully and in such a depraved. Her pussy contracted around him, trying to squeeze more of him out of her, trying to prolong the feeling of release. On and on they both orgasmed in their own way, and even once their mutual climax was over Ruby still oozed from her holes, slowly now; unconsciously, no longer having any sense of self. Several minutes ticked by, and though Zero's stomach finally deflated all the way, the remains of Ruby in messy piles around her body, she didn't get up; the prolonged orgasm proving too much for her poor cow body to take.
The doctor stood to the side, far away enough to avoid the mess she had just witnessed. The clipboard she had been writing on was held loosely in her hand, pen still poised above the paper.
"Well, that was interesting," she mused to herself. "I wonder what would happen with pigs..."
