The Spill
#8 of Junk
My stories are copyrighted, so NO takee! This story was 'inspired' by a great TF sequence of pictures by 'kora' that I saw of a woman being transformed into a horse's cock, so you get the idea! But I've added another 'player' to the story, and added my own 'twist'.
The Spill
By William W. Kelso
The van crept slowly and carefully down the narrow dirt road, the headlights hardly penetrating the dark night, and the steady rain didn't help either. There was no moon, and the stars provided little in the way of light through the scattered clouds.
"You sure about this?" The man sitting in the passenger seat asked the driver.
"Yeah, this is a good place to get rid of that crap." The driver replied, "It's in the middle of nowhere, the only thing nearby is an old abandoned farm. The water will dilute it in no time to the point it's harmless."
"I don't know," the first man said, "that stuff is pretty nasty, what were those eggheads thinking when they made it?! God, did you see what happened to that assistant?"
"Yeah, I did, I was the one that found the poor bastard." He shuddered at the memory of the half human-half cockroach THING that had been scurrying around on the floor of the lab trying to scream. "And you know those guys, anything for science."
"Yeah, tell that to bug-boy!" The driver said with a shudder. They'd had to kill the horrible thing; it had been insane and kept attacking everyone, they'd had no choice. Then he braked, and added "We're here, let's get the hazmat suits on and get rid of that shit, I can't stand even being near it!"
Donning full environmental suits they carefully lifted a small green container with 'Danger-Toxic' warning labels, and dumped the thick greenish sludge inside into the merrily chuckling stream that meandered through the clearing.
"Well, that's it; let's get the fuck out of here!" The driver said, and the other man said, "Sounds good to me, and I'm leaving this suit on until we can do a full de-con back at the facility." The driver nodded in agreement.
As they left the thick green sludge was slowly dissolving into the rapidly flowing stream and moving downstream. Two miles downstream was a small ranch, but it was no longer abandoned.
___________
Tom and Brenda both loved horses, and had bought the old abandoned ranch a few months ago. With the help of a hired hand they had fixed up the place and made it into a fairly profitable animal husbandry breeding business, their specialties being Shire horses. Just one of the gentle giants could sell for thousands. Now that it was up and running they could run the place pretty much themselves, only needing temporary help at certain times of the year.
It was a lovely day as they finished breakfast, and Brenda headed out to the back pasture to check the fences and drop off some salt blocks, while Tom worked on the barn. It was a fair way as the place was fairly large, but she didn't mind the long drive in the four wheeler bike. At noon she'd return to the house for lunch, and then go into town to pick up some feed and other supplies.
As the day progressed it got warmer; the air humid from last night's shower, and Brenda stripped down to her t-shirt and shorts, her large firm breasts revealed in detail under the thin wet cloth. Bet I could win a 'wet shirt contest' she thought; giving them a shake, her breast jiggling pleasurably. Of course she'd never do this in public, but the only one there was their Shire stallion Barnabas. The mares were coming into heat, so they were keeping him separated from them until they were in full estrus and more likely to be impregnated when he serviced them. She walked the fence line making sure none of the posts were loose and the strands of wire were well connected, the hot sun making her sweat even more. And she'd forgotten to bring a bottle of water! Damn! But there was always the creek, it flowed through the pasture, and the sparkling water was cool and clear. They'd tested it before and it was pretty pure, and supplied their animals with water as well as their house through a fresh water well, so she wasn't worried about it. Finishing running the fence she joined the huge horse as he got a drink as well.
"Good, huh Barnabas?" Brenda said as she scooped handfuls of water to her mouth and drank deeply, and laughed when the drinking horse just grunted.
__________
Tom was really working up a sweat as he worked on the barn's roof, a violent thunderstorm a few days earlier had blown off a few shingles, and he wanted to replace them before the next heavy rain. As noon approached he finished, and climbed down the ladder. Noticing that the horse trough was almost empty he turned on the tap, and as it filled with cold water he washed his face and hands, taking a cool drink. Suzy, one of the mares, joined him as she slaked her own thirst. He thought he detected an odd metallic taste, but didn't think much about it.
__________
As they unknowingly ingested the diluted; but still highly infectious, mutagen Brenda and Barnabas didn't really notice anything at first. But soon the preliminary effects began to manifest, *causing both her and the stallion to go into an unnatural sexual heat as they became increasingly aroused in a very short period of time, neither of them even being aware of it at the start. *
*Before she even realized what she was doing Brenda had slid her hand down her shorts and was rubbing her mound, moaning in pleasure. The stallion, a little confused at being so aroused when a mare wasn't in sight, gave a grunt of pleasure as his cock slid out of its sheath as he became rampant. Stripping off her clothes as her heat became even more intense Brenda quickly found that she was unable to satisfy her own lusts by masturbating, her mind fogging up from the irresistible lust as she desperately tried to bring herself to orgasm. Barnabas was rearing and snorting, huge cock jutting from between his legs as he tried to mount an invisible mare. As she saw the rampant and ready stallion Brenda felt her lust increase tenfold, and with an eager moan she staggered towards him, the stallion flaring his nostrils and snorting at the scent of her own arousal. *
At the sight of Buck's huge equine erection; neither of them caring who their partner was at this point, she crouched down beside him and began to stroke his visibly pulsing cock with one hand, the other busy between her legs. She was so far gone in her unnatural need that she didn't resist as Barnabas pulled away and circled around behind her, and then mounted her. She screamed in pleasure as he penetrated her; bracing herself by holding onto his front legs as he straddled her, and could feel more and more of his cock sliding inside her pussy as he lunged in deeper and deeper, and soon cum was squirting from her sex as they began to orgasm almost immediately. With each throb of Barnabas's powerful pulsating and cum spewing cock her body tensed in ecstasy as she experienced waves of multiple low level orgasms, her sex clenching and quivering around the huge organ filling her. It never occurred to her it should be impossible for her pussy to accommodate such a large inhuman phallus, but with each orgasm he penetrated deeper and deeper as he kept thrusting into her writhing body as she sobbed in ecstasy, her large heavy breasts swinging in rhythm with his thrusts, the steadily increasing pleasure the only thing their minds noticed; or were concerned about.
__________
** Tom was surprised as his cock suddenly stirred; then quickly became fully erect, almost painfully so. He hadn't had anything really sexual on his mind, so the suddenly intense arousal was unexpected. He decided that Brenda was in a for a nice 'surprise' when she got back to the house, but after just a few minutes his need became almost unbearable, his cock so hard it hurt. Finally he gave up, and went inside the barn to relieve his need. He didn't notice the way the mare was looking at him; her nostrils flaring, or that her tail was lifted as her own sex began to swell and grown wet. With a hopeful snort she followed the only male she could smell.**
** Tom took off his pants; now wearing only his tennis shoes, and leaning against the wall of a stall he began to masturbate, but though with each stroke it felt like he was going to explode nothing happened, and the pleasure and need kept growing. Catching a strangely exciting scent he looked up to find the mare looking at him, and then she turned around and lifted her tail, her sex obviously ripe. She's offering herself to me; Tom realized, for my services! Though he had never even thought much about bestiality, he found the sight of her wet swollen sex irresistible, his cock throbbing in response. It never occurred to him that his; and the mare's, sudden lack of inhibitions in a sexual partner was influenced by anything. All they cared about was the other was a member of the opposite sex.**
** Tom led the impatient mare to a narrow stall used mainly for sick animals, and after he closed the gate behind her he climbed up an old milking stool he'd found to get the height right, and with a groan of pleasure he mounted her, surprised as how tightly her sex closed around and sucked at his cock, the mare squealing as he penetrated her. Then he began fucking her with a fast steady rhythm. Down deep he knew this was wrong, but he just didn't care.**
__________
As Barnabas's huge cock pushed farther and deeper into her willing pussy; easily penetrating her cervix and entering her womb, Brenda eventually felt the mouth of his sheath pressing against her nether lips as; impossibly, he hilted. Stimulated by their intense sexual pleasure the mutagens began to enter the next stage. As the stallion serviced her Brenda held his front legs and pushed back with all her strength, her pussy clenching and caressing the massive hardness filling her as she moaned and groaned in pleasure. Cum gouted from their tight joining, the stallions balls straining as he pumped her full of impossible amounts of his equine seed as he grunted and snorted in ecstasy, both lost in a daze of sexual euphoria, blinding them as to what was starting to happen. Only the pleasure; their needs, mattered now.
Over an hour of nonstop rutting passed as Brenda and the horse orgasmed almost nonstop, but slowly she realized she was starting to lose the sensation of Barnabas's penis inside of her; the amazing cock giving her so much pleasure seeming to go soft as her mind slowly began to come down from its sexual high, but the horse did not stop thrusting or orgasming. Sally; now confused and knowing something was wrong, felt an intense growing sickening pleasure in her insides as Barnabas's cock kept pumping into her. Suddenly she burped; and then gagged as she felt hot fluid bubbling up in the back of her mouth, and gave a gurgle as her cheeks swelled and her mouth filled with a thick salty fluid, and then with a gasp she opened her mouth and thick white gooey fluid splattered onto the ground.
__________
** Tom gasped as he gripped the mare in front of her hind legs as he lunged into her, and then groaned as he had an intensely pleasurable orgasm, and the mare squealed as fluids burst from her sex to drench his crotch and legs. God; he thought as he kept thrusting, how many times is that?? Three, four??? But there was no real sense of satisfaction, and despite thrusting even harder and faster the incredible feel of the horse's tight sloppy sex around his straining cock seemed to be fading, but it wasn't gone yet and the pleasure was still more intense then anything he'd ever felt before, and he knew he'd be cumming again soon.**
__________
*Oh, oh my God, Brenda realized in shock, that was CUM she was spitting up! Barnabas's huge cock must be doing internal damage; she had been crazy to do this, but surprisingly there was no pain, in fact just the opposite. Despite not being able to feel his cock inside of her very much anymore, the pleasure was still incredible, her body shuddering in ecstasy every time he ejaculated into her. Then to her growing horror she felt her body slowly began to change, skin and flesh turning soft and rubbery, her muscles losing their tone and strength as she began growing weaker. Gripping his front legs she tried to pull herself off his pulsing cock, but something tugged her back no matter how hard she struggled. *
*As her rear began to merge with Barnabas the flow of cum from her pussy stopped as she lost all feeling in her sex; and the flow from her mouth increased. She tried to scream; to call for help, to beg Barnabas to dismount, but the only sounds she could make were liquid gurgles as gouts of cum were now spurting from her mouth in sync with the horses ejaculations, and she realized in amazement she was starting to feel some of the stallions incredible pleasure as his cock...absorbed her! *
__________
** Tom cried out in pleasure as he had an incredibly powerful and intense orgasm, then with a groan he rested against the mare's rump, his cock still buried in her pussy, but he was finally spent. He'd never had such fantastic sex before, and it had been with a horse! Oh God; he thought, what have I done, what was wrong with him?! He tried to dismount and pull himself from the grip of her sex, but instead felt himself suddenly yanked back forward. But it was strange as he couldn't really feel his cock anymore; and pulling back again he looked down, and then blinked in shock. He was joined to the horse!! A webbing of soft black sensitive skin had formed between his crotch and the horse's pussy! With a yell he pulled again, but remained firmly attached, the soft rubbery flesh only stretching a little before pulling him back. And his insides were beginning to tingle, the feeling sickeningly pleasurable. What the FUCK!?!**
__________
Webbing began forming between her fingers and toes; and arms and legs, as the softening skin was pulled upwards, restricting her movements, making her now frantic struggles weak and useless. She lost her grip on Barnabas's front legs as her fingers grew together, and her legs were losing their shape, blurring as they became soft and malleable. Sobbing, she clutched at her throat to try and make the gouts of cum stop; but her fingers had grown together and her now clumsy lump like hands had no dexterity and the stallions orgasms were steadily increasing in strength and longevity; and she felt what he did; her pussy now gone, gurgling in unwanted pleasure as each spurt of cum blasted from her mouth as she...ejaculated. But despite the constant surges of almost unbearable pleasure Brenda's mind was now fully aware of what was happening and filled with horror. As her legs were lifted from the ground as they were absorbed her upper body fell toward and landed in the large puddle of cum below her; her now boneless stubby arms unable to bear the weight any longer, leaving her wallowing in the large puddle of fresh cum she was still helplessly spewing. The rest of her skeletal structure had already begun to soften and collapse as it became penile flesh, leaving her body visibly pulsating with Buck's pleasure every time he came; his cum pouring from her mouth, the horse snorting and squealing in ecstasy.
__________
** Tom screamed and yelled as he pushed desperately at the mare's rump, but the webbing of soft black flesh joining them was spreading, and his legs were going numb as he lost feeling in them. Like boneless sacks they dangled; no longer touching the stool, as they were slowly drawn upwards. Staring in horror he watched as his fingers began to grow together, his skin turning black as the horse's vagina absorbed him. Mewling in terror he slapped his increasingly useless and boneless arms against the mare's rump, but her only response was to squeal and snort in pleasure as she kept cumming and orgasming.**
__________
*The pulsing of Buck's new rapidly forming penis increased as most of what remained of Brenda's lower body and legs were pulled into his sheath, causing his balls to swell with cum as they were absorbed. Her increasingly penile shaped body was turning a mottled black and pink color, thick veins visibly throbbing beneath the surface as it pulsed and throbbed and slowly spread down her body, and she stared in horror at the huge amounts of cum gushing from her mouth, the last remnants of her legs melting as the stallions steadily growing testicles turned them into fresh hot cum. Brenda knew there was little time left for her as her hips were slowly drawn inside the horse's sheath after her legs, the huge animal easily absorbing her body weight. Brenda felt the sickening pleasure in her guts peak and then fade as her internal organs were dissolved, and she realized she could no longer feel her own heartbeat, the veins on her body pulsing in rhythm with Buck's heartbeats now. She clawed feebly at the ground as her arms shrank and melted into her chest, her large breasts deflating and shrinking until only the nipples remained, then they too faded into nothingness. Please, please stop; the thought, this is insane! *
Slowly Buck stopped cumming as his orgasms stopped, and Sally felt her impossible new 'body' begin to go flaccid as her blood slowly drained up into the horse; her softening body being dragged backwards through the huge pool of cum, leaving her head hanging down between Barnabas's rear legs; helpless, staring around in horror, cum still drooling from her mouth. But it wasn't over; the horrible changes slowing down now that Buck's lust had finally temporarily satisfied, but the final horror was still to come.
__________
** Tom cried and wriggled helplessly as the mare began to pull his softening body into herself; his legs were gone, his arms now merely uselessly flailing nubs. With wet schlucking sounds his collapsing pelvis and rear were suddenly sucked inside the horse, and his upper body fell over backwards leaving him dangling behind the horse. Raising his head he could see that he had been swallowed up to his waist, the black skin now reaching his neck. The sickening pleasure inside had faded, and now only a strange growing sensation remained. Then he realized something as the sensation increased; she's not eating me, I'm becoming part OF her! I-I'm becoming her...oh GOD NO, NOOOO! Flopping helplessly he struggled desperately, NOOOO!**
__________
*Oh God, oh God, is it over; Brenda wondered? For awhile she dangled, trying to call for help, thick cum still drooling from her mouth as she gurgled and slobbered. She wriggled a little bit, but that was all the movement she was capable of, and she had lost all contact with; and sense of feeling, in her arms and legs. Oh my God, she thought in disbelieving horror, I'm Barnabas's cock and balls now!! I-I'm a HORSE cock with a human head! She could FEEL her horrible new body, the thick tubular shaft hot and sensitive, the sheath wet and slick inside, the huge balls throbbing as they rapidly filled with new cum, the feeling incredibly pleasurable. *
Then she gave a loud gurgle of horror as she felt the changes starting again, and her hair finished falling out as the skin of her face turned pink and slick. She felt her face swelling and bulging, and slowly the skin that was once her neck and shoulders stretched and grew as it rolled forwards and slowly engulfed her head, the new foreskin covering her terrified eyes and face, leaving only her mouth exposed. Brenda struggled with what little control she still had, the huge cock swinging slowly with the head dragging in the thick puddle of cum. Her remaining human features stayed hidden under the foreskin while her head kept changing slowly with each dribble of cum from her gasping gurgling mouth as her teeth softened and merged with her gums and lips, her efforts to scream useless as her mouth began reforming into a vertical urethra slit. Her nose dwindled and faded until there was nothing left but a cock head and a pre drooling piss slit where her mouth had once been, her eyes blinded by the foreskin covering them. The cock gave a final squirm, and then hung limply, pre oozing from its slit. All that remained was a huge cock dangling between Buck's legs, the lower portion equine, but the head vaguely shaped like a human phallus. It continued to drool a slow steady flow of pre and cum as the huge organ began slowly shrinking.
__________
** Tom was completely helpless as he was slowly drawn into the horse's rear, his now soft and toothless mouth only capable of making loud wet smacking sounds. It was the strangest sensation as he felt himself becoming part of the horse, and he knew with horrible certainty he was rapidly becoming the mare's vagina and probably its uterus as well. With a final inward tug his face sank between the mare's rear legs, his lips swelling; turning black and rubbery and splitting his face vertically as they became the sensitive lips of her sex. They pulsed and made 'kissing' motions for awhile as the final changes took place, then settled down into their new form and function, the fluids of the mare's heat dripping from them, the spicy flavor filling his 'mouth'. The only human features remaining; hard to see under the tail, were two small horrified eyes flanking the mare's large puckered anus. Tom tried to scream, the black lips flexing a little and drooling more fluids, but that was all he was capable off. And he could feel the mare's need; feel her heat, taste it, his whole 'body' aching for relief. T-This is impossible, insane, obscene; he thought, but it was also horribly real. I-I'm a horse's pussy! N-NOOOOO!**
__________
** Slowly Barnabas's cock shrank to a size more suitable for the now even larger Shire stud as the puddle of cum kept growing. Brenda could only hang helplessly as the cum flowed through her thick tubular body, the feeling very pleasurable. Any of her efforts to move only resulted in a barely noticeable squirming. And as she shrank and went even more flaccid she was slowly drawn up and into 'her' sheath. Finally only a few inches still dangled from the stallion's sheath, and the foreskin drew back enough for her to see. There wasn't much to see as the exhausted; but happy, stallion began to graze. He seemed to have no idea as to what had happened to his 'partner'. Brenda stared at the ground and the underside of the stallion's body in despair, horribly aware of her new body and the massive balls which she could also feel. And soon she felt an increasing flow of blood into her 'body' as Barnabas's lust began to return and she began to swell and slide back out of his sheath. With an eager snort he headed towards the barn in the distance. Brenda of course went along helplessly, and she knew what was on the stallions mind. Breeding season was just starting, and she could feel his lust, feel his need. Oh God, NO; she thought, as she dangled and flopped around; slowly growing harder, as he trotted towards the barn.**
__________
** Tom just stared helplessly; there was nothing else he could do. Even with her tail down he could still see a little through the thick hair, but there wasn't much to see, just the walls of the barn. He thought it should feel as horrible as it was terrifying to be in his current; and probably permanent, 'condition'. But it actually felt rather nice, even the mare just moving caused twinges of real pleasure as his 'lips' rubbed together. Even when she urinated the feel of the hot fluid pouring out of his 'mouth' was a strangely pleasurable feeling, even though he was grossed out by the taste and closed his eyes so he wouldn't have to watch. But it was the other feeling, a growing need; that was the most disturbing. Of course he knew what it was, how could he not? After all, he was her sexual organ now. He knew fully well what was going to happen as soon as she found a stallion, and though horrified a part of him could only feel... anticipation as well. What would it feel like?? But he hoped that; somehow, someone would realize what had happened, and they could find some way to reverse this obscene horror. But a part of him also realized that was doubtful, the only evidence that remained to show the merging was his eyes, and they were small and probably hard to see, especially with the tail down. He flexed his 'lips' a little, more spicy tasting pungent pheromone laced fluids dripping from them as he quivered in need. Or maybe he hoped she'd find a stallion first after all; and he quivered as he tried to imagine what it would feel like to be...serviced.**
__________
** Barnabas snuffled at the air eagerly as he neared the barn, his penis now fully extended and partially erect. He could smell the mares! But one's scent was much more concentrated then the others; she was in full blown estrus, and he approached her with his intent obvious. The mare was a little skittish, but let him 'herd' her outside into the paddock. She had been serviced by him before, and was no stranger to what was coming, but her need had never been so intense before.**
__________
** Brenda was helpless as blood pumped into her body and she began grow more rigid as her body stiffened and swelled. She squirmed a little until she became too hard, thick pre drooling from her 'mouth'. Her foreskin had slid back and she could see clearly, but so far all she saw was the ground and Barnabas's stomach and front legs as he moved around. As he became more aroused she felt herself responding; there was no way she couldn't, as her body got harder and harder, veins pulsing on the surface, salty sweet pre oozing from her slit in steadily welling drops, his arousal pounding inside her. Her body throbbed and ached, leaving her dazed and giddy from lust, her swollen balls aching to be drained. She'd never felt such need, such anticipation, and it just grew and grew. No, NO, NOOO, but...the NEED!**
__________
** Tom caught glimpses of another horse behind the mare, and as she lifted her tail he found a large snout pushed close to him, nostrils flaring. Oh my God, it's Barnabas; he realized! He tired to say something; tell the stallion to go away, but all he could do was smack his lips wetly, thus increasing the flow of sexual fluids. Buck took another deep snuffle, and then gave a loud snort as he backed away, his intent obvious. Oh shit, Tom thought, as the flow of fluids increased even more, and an exhilarating feeling washed through him. He was ready, and God help him, eager! He needed, wanted, what was coming.**
__________
** Barnabas 'courted' the mare for a short time longer, and then when she lifted her tail and braced for him he reared up and started to cover her, lunging forward as he slid further up on her back. She was a Shire too, but he was much larger and was able to mount her fairly easily, and as his aching cock; he'd never been so aroused before, found the right angle he gave a squeal of ecstasy as he lunged forward and plunged into her, and hindquarters pumping he began energetically fucking her. Grunting in pleasure he nibbled at her mane, the mare squealing in pleasure.**
__________
** Brenda was now totally committed to what was coming, she wanted, needed, it, after all she was a penis now, her balls aching to be put to the use for which they were intended. Her rigid blood swollen body throbbed and ached with a feeling she couldn't describe, and only one thing would satisfy that feeling, that need. A small part of her was still horrified by what was about to happen; and knew it was probably a big mistake, but she was helpless, merely 'along for the ride'. But most of her wanted it, desperately so. So when Barnabas began to rear and she saw the mare's hindquarters; tail lifted and thick rubbery lips drooling in welcome, she wished she could scream in exultation. As the stallion lunged forward she moved closer and closer towards what she needed so badly, pre squirting from her slit in small jets, but she wasn't so far gone that she didn't notice two green eyes flanking the top of the mare's pussy, eyes staring at her in a mixture of horror and pleasure. Tom had green eyes. As her head pushed against, then slid into the mare's slick wet vagina, she exchanged a look with him and knew he realized who; and what, she was now. Somehow she found that both horrifying and comforting; horrified he had also undergone an impossible change, but comforting in that she wasn't alone with the horror and ecstasy as she slid deeply into his embrace. She felt the lip of her sheath grind against the lips of the mare's sex, and then Barnabas began fucking the mare with steady powerful thrusts, and her senses exploded into pure sexual euphoria.**
__________
** Tom stared as Barnabas reared up and came down on the mare's rump, then with short hops he began to cover her. He could see the stallion's huge rigid cock bobbing and drooling pre as it came closer with each lunge, and he stared at it with resigned horror and anticipation. But as it came closer he realized there was something different about it, the head looked more like a man's cock, blunt and with a vertical urethra slit instead of a flared head and round hole like a normal equine penis. With another lung it slid even closer until it was only a few inches away, and he saw the blue eyes looking at him filled with fear and lust. Brenda had blue eyes! As the head of the cock pressed against his eager welcoming lips he stared into those eyes and saw the recognition in them, then they disappeared into him along with several inches of thick shaft, and with a few more lunges the stallion finally hilted, and then began servicing the mare, both animals squealing and snorting in pleasure. As he swallowed the huge cock, helplessly clenching around the shaft, he'd never imagined such pleasure as it filled him. He could feel every inch of it buried deep inside his slick hot embrace as it slid into him, and he sucked at it, trying to pulled it back in every time it partially pulled out before thrusting again, wanting it as deeply inside as possible. He could tell he was stretched to maximum by the huge invader; that it was much larger then would be normal for him, but that just made it even better. With every massive thrust the pleasure just increased until it reached a point it was unbearable, and he slowly drowned in a sea of pleasure until that was all that existed as every inch of his incredibly sensitive new body was stimulated by the hardness filling it.**
__________
** Brenda tried to scream in ecstasy as she slid inside the slick velvety smooth tunnel encasing her body, the vagina's powerful muscles clenching and caressing her straining body. So much pleasure should be impossible, but with every stroke the ecstasy just increased, and she knew that soon she would reach a point of release that was inevitable, but that there would be a price for that release. She tried her best to resist, but was helpless, and all too soon she felt a sudden surge of pressure deep in her balls, and her body began to pulse and swell as a massive flow of cum began surging through her, and as it exploded from her slit she gave a silent scream of despairing ecstasy as she came, and came, her mind fading into an explosion of incandescent pleasure. **
__________
** Barnabas threw his head back and gave a deep grunting bugle of pleasure as he felt his cock explode deep in his mates body, his whole body trembling as he lunged in as far as he could and froze until the ecstasy slowly faded as his cocks powerful throbbing pulses slowly slowed to a stop. He rested for a few minutes, his front legs gripping his mate, then; much to his own surprise, began servicing her again. He had never done this before, but he wasn't satisfied yet, so it was nice. The mare didn't seem to mind either.**
__________
** Tom's mind reeled in ecstasy, his whole 'body' sucking and clenching desperately around the huge hardness filling it as it slid back and forth. How long can this go on; he thought, his eyes watching as the slick dripping shaft slid in and out of his 'mouth', fluids squiring from the tight joining. The massive shaft was crisscrossed by a tracery of visibly pulsing veins, and he could even feel them against his sensitive insides. But soon the agonizing pleasure began to reach a peak he knew he couldn't resist, and when the stallion suddenly lunged in and he found his eyes right next to its balls he felt the shaft suddenly swell even more, and as powerful spurts of hot cum filled his quivering insides he gave a silent scream of pure and impossibly intense pleasure as he stroked and clenched around the pulsing cock, sucking every drop it had to give as wave after wave of that horrible pleasure slowly wore away his awareness in a torrent of irresistible bliss. And as his thoughts faded he realized; this is what I am now he finally accepted, and it's wonderful.**
*__________ *
** As Barnabas kept servicing the mare he had the most pleasurable; and longest lasting, sexual experience of his life as he brought them both to five magnificent full blown orgasms. As he did his massively oversized balls slowly shrank to a more normal; but still impressively large, size for a Shire stallion. And stimulated by the sexual pleasure the changes continued. Slowly the happily grunting horse became aware of a tingling in the back of his head, feeling like it was behind his eyes. It was a little annoying, but not painful, so he just ignored it at first as he kept mating with the mare. Unknown to him the mare was starting to experience a similar sensation in the back of her mind, a feeling like the fluttering of a moth. But the feelings increased with each orgasmic relief, and suddenly it felt like a dam had burst as new thoughts and memories flooded their confused equine minds. But after a minute of fear they calmed down; still moving together in mutual ecstasy, as they first recognized, then accepted, the new awareness flooding into their minds. It was strange, but nothing to be concerned about.**
__________
** Brenda drifted in a strange and frightening place as the waves of irresistible pleasure swept her mind away in confusion. Every time the pleasure peaked as another orgasm exploded in her body she slowly began to lose touch with it; she remained aware of the pleasure, but it seemed to be thinning out, diluting as she slowly became aware of even more sensations. She felt her awareness bump against another, then began to push against it harder. Terrified, she did her best to resist, but her struggles were useless, and suddenly in a blast of utterly confusing and strange sensations she realized she could see again!! The other mind she had felt merging with hers became more and more 'familiar'; the feeling strangely enjoyable as new needs and instincts flowed into her own mind and the pleasure returned as the two became one, inseparable. She blinked and found herself staring down a long black and brown muzzle as she thrust and squealed in pleasure, and as the most incredibly pleasure feeling exploded between her legs she threw her head back and bugled in ecstasy. Oh my God, she realized, I'm Barnabas now!! I'm a...a horse! And I'm MALE! Very much so! Then with a final guttural grunt of pleasure she dismounted, her cock sliding from the mare's vagina in a spray of fluids, the cock now 100% equine, nothing human remaining.**
__________
** Tom tried to understand what was happening as the intense pleasure pushed him more and more into another mind, it's instincts and memories merging with his, the pleasure finally fading only to return in a new; just as intense way, as he slowly became aware of a heavy weight on his bad, a hardness filling his nether and giving him unbelievable pleasure, and the fact he was looking at a wooden wall, his mouth open as he squealed in ecstasy. Suddenly the pleasure peaked, and he squealed as a massive orgasm racked his body, trembling in ecstasy from the feel of hot cum filling his sex until it overflowed. Then the heavy weight slid from his back, the hardness from his quivering sex, and he found himself staring down a brown muzzle at a dirt floor as he breathed heavily from the exertion and fading pleasure. I-I'm Suzy now; he realized in shock. I'm a horse! A mare! And I've just been fucked!! He/she gave another squeal of pleasure; nothing had even felt that wonderful before!**

** Barnabas/Brenda stood still for awhile, his penis slowly going flaccid and retracting into its sheath. I'm a male horse; Brenda thought, still shocked and confused, but not exactly unhappy by that realization. This is...isn't bad. He snorted, lifting his head and looking around. He could smell the other mares, and knew they'd be ready for him soon. No, not bad at all. He felt his cock give an eager twinge inside its sheath, and snorted in amused anticipation. This sure beat the...other alternative, though he had to admit being his cock had been...interesting. But wait, I'm Brenda, not a horse! B-But I'm a horse too, a stallion! How strange. She looked at the mare standing in front of her, and both parts of him/her recognized her. It was Suzy, and I just fucked her! As a cock, and then a stallion. God that had felt incredible! Moving forward he gave Suzy's flank a gentle nudge, then began nibbling at her mane. It just seemed the right thing to do.**

** Tom gave a shudder as another small wave of pleasure rippled through her still quivering vagina. That had been...unbelievable! This whole thing was, first he had been absorbed and became Suzy's pussy, now he WAS Suzy! But this wasn't so bad; it sure as hell beat the alternative! Being a female sexual organ had been...interesting, but was certainly not how he would like to spend the rest of his life! And speaking of his; or rather her, life, what now? As the stallion she could smell behind her started nibbling and lipping her she gave a snort of pleasure and turned towards him, familiar blue eyes staring back at her, a horse's in everything but color and the intelligence shining in their depths. Brenda?? She thought, both of them making grunting noises as they tried to talk, until giving up to keep grooming one another. It would appear their bodies where entirely equine now; the horses having absorbed their human body mass, and only their minds were still part human. But soon enough their 'foreplay' became more serious as their needs returned; and both gave loud squeals of pleasure as Barnabas mounted Suzy again.**

** Tom; or Suzy as she thought of herself now, leisurely grazed on the thick sweet grass and clover, then paused and gave a soft snort as her swollen belly suddenly gave a kick. She knew she would be dropping her foal soon, it was almost time. She and Brenda/Barnabas had given up trying to 'tell' anyone what had happened to them long ago; and as their minds finished merging with their new bodies it just seemed to become less and less important. Oh, she still remembered she had once been a male, and human, but accepted that she was a mare now. She had memories of giving birth before, and it didn't bother her at all. Barnabas felt the same way, and the small herd of very pregnant mares in the field gave proof that he had embraced his new masculinity with upmost zeal and dedication. **
** Lifting his head Barnabas walked over to Suzy and gave her an affectionate nibble, the mare happily returning the affection. They would both always know their 'secrets', but were perfectly happy like they were now. The sex was especially great, and mating out of season was one human trait they'd held onto with delight. But not right now, she was too close to giving birth. But afterwards, oh yeah!**
** They were happy with their new owners, the younger couple had two children who helped with the upkeep of the herd, and they enjoyed being around the humans. After their 'mysterious disappearances' they had been sold at auction, and fortunately they'd been lucky to be kept together as a pair; in fact most of the original herd had remained intact. Other then noticing their 'unusual eye coloring' no one had even come close to putting two and two together. After all, who would believe that the horse's sexual organs had first absorbed their former owners, and then they'd become one with their new 'hosts' mentally? Sometimes that seemed like nothing more than a dream anyway.**
** As for the mutagen it was indeed greatly diluted, and the only other affects it had was when it reached a town's water supply everybody's sex became fantastic for a few months, not that anyone complained.**
** The End**
