It had been a long-awaited plan for Madison and Nadine to sneak into the abandoned dorm that night. It wasn’t that well-kept a secret on campus that a boarded entrance could be pulled away from a certain angle. Still, it was questionable why the campus hadn’t properly sealed it shut, given that the residence was considered a hazard, set to be demolished sometime in the near future. Such a place would be perfect for parties out of the watchful eye of campus police. And yet, it lay largely untouched, save for what the two girls had in mind.
While rumors of hauntings were enough to deter most people from the premises, Madison had wanted to check it out the moment she’d first found out. Frat pledges were often dared to do so as part of initiation rituals. However, it was something that most people regretted upon removing the board and exploring the first floor. Generally, they would quickly rush out without discussing what they had seen, and that alone was a deterrent for most. Madison, however, had been a fan of the paranormal for as long as she could remember, and such a possibility left her more eager, not afraid.
With no other friends in their circle who wanted to go, Nadine figured it was imperative to make sure she went along so nothing happened to her friend. Not that she figured a phantom or the like could get the better of Madison, Nadine always having been skeptical about the supernatural herself. However, there were a myriad of things in an abandoned building that might be dangerous. Loose nails, broken floorboards, or perhaps getting stuck behind a locked door were all possibilities, though Madison was happy to have the company regardless of her intention. They had been roommates for their entire tenure at college, and despite their differences in interests, had become fast friends. Even the risk of being fined or banned from the dorms was not enough to keep Madison away, as much as Nadine reminded her of such. For better or for worse, Madison had made up her mind, and all she needed was to pick the right night.
True to word, the wooden panel came off with ease, and the two of them shone their flashlights in the dank hallway of the basement. The entrance was along the side of the building, around the laundry room. Dusty machines still lined the walls as their flashlights carefully danced, trying their best not to be caught out of any windows. The odds of them being spotted by campus security were slim, but not impossible. Still, they made their way carefully out into the hall, Madison hoping for any signs of the paranormal.
The two girls explored the first floor silently, turning up their lights while they remained in the hall. All the windows were in the dorm rooms on either side, and as such, Madison wanted to explore for discarded treasures. Aside from cigarette butts and beer cans, there wasn’t much of interest, such had likely long since been looted. A film of dust lined the surfaces, and the musty smell was almost enough to make both girls sneeze. But as they made their way up the stairs to the next floor, nothing seemed out of place, looking like a normal, albeit abandoned, building.
“Damn, I got my hopes up for nothing,” Madison eventually relented as they made their way to the third floor, having checked each hall and the main lounges. Why they would be fined for trespassing was a little silly, but it was likely to deter the gathering of partiers. Even signs of those who dared to enter and fled were absent, lending credence to the likelihood that they were simply scared and ran out before anything of note happened. Madison thought she would be so close to the possibility of the paranormal, and it was a dud!
“Want to head back?” Madison finally suggested, and Nadine breathed a sigh of relief. In truth, Nadine hadn’t wanted to stay this long, but there had been little point in protesting. She simply nodded, glad that Madison was finally bored. There would be no story, no brush with the paranormal. But at least they could get back to the dorm room without being caught or punished.
“Yeah, that’s- oh, wait, what’s that?” Nadine asked, her flashlight settled on a board game in the corner of the upstairs lounge. Madison was quick to shine her flashlight over the table, and her eyes widened in curiosity. She recognized the thing as an Ouija board, something she had used a few times but not to great success. Still, Madison ran toward it, and Nadine found herself following, hoping nothing would come from it. It turned out to be the worst mistake of her life…
“Let’s try it!” Madison declared, reaching around to look for the planchette. Finding it, she placed it on the board, motioning for Nadine to place her hands on it as well.
Balancing her flashlight so that it illuminated the table, Nadine did so, though she maintained an expression of skepticism. “Wasn’t this campus the site of a farm before? What are we going to call on? The spirit of a horse or something?” Nadine teased, though Madison remained serious.
“Maybe someone still died here, you know?” Madison said, asking out loud a question. “Is anyone listening?” She waited breathlessly for the answer. Yet, as the two of them relaxed their hands, the tug of something forcing it never came. Nadine gave Madison an impatient look. She was willing to wait for a moment to see if something happened, though ready to encourage Madison to leave if nothing did.
Yet, rather than feel the planchette move, a sudden, loud crack from the wall made both of them jump. Different than a simple knocking, it was almost as though something was stomping with four hands at once. Perhaps as though an animal was clopping along the walls, though the mental image of a horse from their farm conversation likely tainted their perception. Still, as another set of clops came from the other wall, both girls could only gaze at each other, the same thoughts crossing their minds.
“Fuck…there’s no way…” Madison whispered in disbelief. She’d wanted to experience something, but now, having done so, the fear left her paralyzed. The sounds seemed to steadily rise in crescendo around them as though a whole herd of animals were stomping through the walls. Getting down on her knees, Madison was barely aware that Nadine had done the same, both girls putting their hands on their ears, trying to protect themselves. Such was likely useless, but the sounds were so loud that neither could think of anything else to do.
Just as suddenly as the stomping came, it stopped, leaving both girls to shiver there on the floor. Eventually, Nadine got up, reaching down for Madison to take her hand. She rose, terrified, before looking toward the door. “Time to leave now,” she demanded, not worded as a question. This time, Madison was not inclined to be stubborn, grabbing her flashlight and playing it over the room one more time before they bolted.
Terrified as they were, Madison almost didn’t notice the planchette on the Ouija board as they made their way to the door. Yet, Nadine’s cry of fear had her turn around, unable to believe what she was seeing. The wood was moving of its own accord, from letter to letter in a pattern that suggested a message. “Don’t-” Nadine started before Madison raced over, desperate to see what it was. Surely, she had seen enough, but the temptation to discover one more proof of an afterlife was too much for her to resist.
Waiting at the precipice of the door, Nadine tried her best to call for her friend as Madison watched the message with confusion and then terror. As much as she didn’t want to wait, she couldn’t live with herself if she left her best friend behind. It seemed that Madison was almost stunned by the message, and against her better inclinations, Nadine crept toward her, needing Madison to come with her. Yet, curiosity overcame her as well, and as much as she wouldn’t look at the board, she had to ask Madison what had her so captivated.
“What does it say?” She whispered, afraid of an answer.
Face white as a ghost, Madison turned to her friend before whispering back to her a single word. “Whinny.”
No sooner had the word left her lips than the board started to shake, flying across the room as both girls screamed. The sounds of stomping hooves washed over them once more, though now they could perceive a light racing toward them from either side. As though spectral stallions had burst into the room, the two wild horses danced around the walls far faster than either woman could perceive. Trying to get up was to no avail as the two phantoms dove toward them, seeming to bury themselves in each other. Rather than being rammed into the floor, however, only an intense warmth seemed to enter them. After a few moments, both stood up and brushed themselves off, wondering what the hell had happened.
“What was that?” Nadine asked, certain there had to be some projector or hallucination that caused what they had seen.
The moment Madison went to speak, a strange tension started swelling in her throat, as though something was caught there. Madison struggled for a moment, though the longer she waited, the worse it grew. Soon, there was little choice for her than to open her mouth as she coughed and tried to clear the irritation.
“Neeeiiigggghhhh!” She called out, hands moving to hands to her lips the moment she realized what she had said. “Did that come out of meeeiiiiggghhh?”
Fear crossed her face as Nadine went to talk as well, only to struggle for a moment, before she, too, erupted with a “Neeeeiiiggghhhh!” Both women looked at each other, silent and frightened as though they were possessed. Not being able to speak, the two shifted their gaze toward the door, figuring they needed to get out of there before things got worse. That was unless it wasn’t already too late!
Yet, both were soon overcome with a strange bloating, causing them to keel over and hold their stomachs. Madison, in particular, was left to call out with an equine cadence as the tension in her ass grew far faster than she was prepared for. It was already so massive that she couldn’t pull her pants down. Worse, perhaps, was an ache in her spine that started to press her tailbone against the back of her underwear. She could almost detect the cracks within as the segments parted, pushing into a noticeable bump that seemed to writhe outward. The pain emanating from its confinement was almost too much to bear, though Madison did her best not to cry out, afraid of the horse sounds that might escape her throat.
Nadine, too, was struggling with an intense tightness, this one coming from her shoes. The toes within were numb, tingling as though they were mere phantoms of their former selves. She couldn’t quite reach down to pull them off, the aches racing through her body somewhat too much to handle. She was left to feel the pressure expanding, though not as painful against her toes as perhaps it should have been. Nadine was alarmed, barely able to perceive it now as though her toes were losing sensitivity. Attempts to wriggle them triggered no reactions, something that left her scared to the core. She was unable to do anything but stare down, struggling within her shoes from a force she could barely perceive.
Her fears were only cemented as the sides of her shoes burst open, something thick and gnarled exposed within. She could barely feel the leather around it, though a slight pressure was a sign it was still part of her. As more of her shoes tore away, Nadine was startled to realize that what she was staring at were her middle toes, though hugely warped. The remnant toes were still present, though perhaps not for long, as they steadily shrank into the skin of her stretching heels. The skin itself was almost black, and with some alarm, an itching erupted as thousands of hairs peppered the surface. Soon, they were spreading under her pants as her calves swelled under the denim.
“Noeeeeiiiggghhh!” Nadine called out, unable to repress her whinny at the realization. Kicking out as best she could, the remnants of her shoes and socks flew across the room, exposing what could only be considered heavy horse hooves. Lifting her legs only made her aware of how massive they were, the keratin spreading and leaving her unable to perceive where her toes had been. Nothing remained of the rest of them, having been pulled inside her feet to be dissolved. As heels stretched impossibly long, it was obvious she would not be getting up to run, perhaps until the rest of her body altered to keep up.
All the while, Madison struggled with her swelling ass, pushing precariously against her pants as though threatening to tear through at any moment. Unable to pull them down, the pressure was soon to do them in, fabric tearing and panties popping apart. The warm air on her anus made her shiver, the skin becoming thick and meaty. It was disgusting, though made worse by the itching of long hair against, making her shiver. Looking back only confirmed her worst fears that her spine had pushed out into a semblance of a horse’s tail. Its hairs were steadily getting longer, and the more her hips parted, the more of her asshole was left exposed. It was powerfully embarrassing, denim tearing further down her hips and thighs to make room for the changes.
At that moment, both women felt their ears twitching, reaching up to rub at them in vain. Their velvety contours started to swell, canals widening and muscles allowing them to move nearly around the sides of their heads. Rather than the sounds of the night outside to catch their attention, however, something within their minds seemed to resonate fiercely, as though they were hearing an entire herd of horses. Such was impossible, though the sounds seemed as real to them as though they were present in the room with them. Galloping horses, the sounds of crackling flames, and the panicked whinnies left them terrified. It was perhaps just a glimpse of what might have happened to the beings who had possessed them, though it was of little reprieve when the transformation carried steadily onward!
Even the long-lost scents of past stallions were becoming more familiar to them, which came as a shock. It took a few moments for them to realize their noses had expanded, flat, rubbery, and itching with sparse fur. Terrified glances crossed their features as they rubbed them in tandem, feeling their contours stretching toward their lips. The scents in the room, musty and dull before now, seemed to wake something in them, making both shiver in confusion. Odors they could only associate with fear and terror from their sweat came to their awareness. Worse, they were growing more and more pungent the more their skin was converted to horse hide.
Yet, even through their fear, something more randy and pungent soon reached their nostrils, making Madison quiver and shake. It took her a few moments to equate the scent to sex or arousal, something that should have been repulsive. But it mattered little as the heat in her loins burned to the point she could think of nothing else. Before she knew what she was doing, her hand had reached into the torn front of her panties, her moist, leaking slit sending shivers through her being.
“What are you doooeeeiiiggghhhh?” Nadine called out, but it seemed that Madison had no such shame in her current state.
“Can’t help it…so horrneeeiiiigghhh!” Madison whinnied, unsure what was turning her on about the change. Was she about to develop a mare’s cunt? Such seemed bizarre, though there was little about the experience that made any rational sense, and she was forced along for the ride. It was like nothing she had felt before, made more intense by the fact that both reeked of sweat and horsehide. The equine musk seemed to be the exact thing her changing sensibilities craved!
Nadine went to call out once more, though the sensation of her own ass rapidly expanding caused her to whicker her discomfort. Hips and thighs were swelling at a rapid pace, leaving her no ability to pull off her clothes. As a heavy tear ran down the back of her pants and panties, a stronger whiff of equine musk hit her nose, and Nadine was embarrassed to feel her own cunt moisten. As much as she wanted to resist, the sight of her friend partaking of her sex made such impossible. Soon, her own hand was in her panties, playing over her pearl and causing her to whicker as well. Even the force of her growing ass could hardly dissuade her, changing body more of a turn-on than she could have imagined.
Madison’s own masturbation seemed to be accelerating her changes, though in the heat of lust, she was remiss to care. Her curly black hair started to lighten, becoming thicker and coarser as her bangs landed in her face. Madison could tell her neck was thickening, pushing at the collar of her shirt as it continued to pull up around her barreling belly. She was getting so large, skin persistently itching with the spread of equine fur. But even in the face of such a drastic change, Madison could hardly bring herself to stop. Lust was burning through her and making it impossible to think beyond the now. Nadine tried to call out to her, but her voice was lost in the equine whinnies. Worse, was that the cry carried lustful tones of its own. Maybe if she finished, then she would be able to think…
It was the sensation of something swelling within her groin that caused Madison to pause, leaving her powerfully uncomfortable. All she could think to do was to rub her sex faster, desperate for the pleasure to override the ache. It was like something was waking from deep within, moving lower and preparing for its alteration. The larger it grew, the more frantically Madison rubbed herself, wanting to bring about an orgasm so she might be free of this torment. Especially as her nub began to swell, its sensitivity growing with each passing moment. Her pleasure seemed to transfer toward her pearl, stimulating something deep within her ass, bringing her closer and closer to the edge.
Nadine could only watch with reverence, one hand reflexively reaching back to play over her massive ass. As the stitching parted to allow her to tease her anus, she whinnied her pleasure, finding the touch somewhat strangely erotic. More so was the sight of her friend masturbating, both of them sweating and smelling powerfully of a barn. The animalistic odor was really doing it for her, Nadine falling into bestial lust in a way that defied her understanding. The equine alterations were becoming welcome; her previous fear was replaced with a growing need. Even the sensation of her spine stretching, the nub of her tailbone extending and itching with its own hair growth was exciting. Seeing Madison’s backside made her long for her own equine ass hole, something that was developing more rapidly as she rubbed her clit through her panties.
Yet, despite her desire for the change, the sight of Madison’s altering sex soon caused Nadine to pause. Her friend’s clit was larger, having pushed past the hood and was dangling with its increased girth. Madison’s face was scrunched in an expression of pleasure, ears twitching and lips pulled back in an effort to drink in her musk. It seemed she was unaware of the growth, save for the pleasure it gave her as she continued to rub it. One hand was even able to wrap around it as though encouraging it to grow. The other was massaging her cunt, moist from her juices as she frantically rubbed the discomfort from her insides. It was clearly getting worse, and as Nadine stared, she was sure something was pushing from within, as though Madison was giving birth.
A whinny of pleasure escaped her lips as her fingers teased her clit, now several inches long and much thicker. To her seeking hand, it almost felt like she was stroking off a penis. Such would have been alarming if she had control over her facilities. Yet, it was simply too good for her to stop, and the more she stroked her new meat, the larger it seemed to swell. Soon it went well beyond the dimensions of a human penis, its skin turning black and mottled and leathery to her touch. A flared head seemed to swell from its apex, and to her surprise, her fingers were soon soaked in a sticky fluid, squelching between them as she jerked off with no regard for her situation.
All the while, her other hand was steadily being pushed out of her sex, the space rapidly diminishing as whatever growth within worked its way out. The slit itself seemed to be sealing, though not fast enough to prevent the swelling orbs from escaping. A black, fleshy mass soon pushed out as she groaned, her masturbation the only thing preventing the ache. While it didn’t seem to have enough room on her groin, the force of its expansion could not be denied. Its girth pushed through her remnant cunt lips with the last bit of elasticity they had. As grotesque as the sack itself was, it seemed to possess something ovular within, popping through her opening and causing her to whinny her last threads of female orgasm. While off-centered, a second pushed through just as its exit sealed the space between the sack and her growing horse cock. Madison was thankful she was sitting down, the weight of her new ball sack not so uncomfortable in this position. The fact that she was male now mattered little, especially in the face of her change into an animal. Besides, they were so massive that Madison could only whinny her need to have them emptied!
Nadine could only look helpless and terrified, made worse by the fact similar sensations were crawling through her own cunt. Her nub soon began to swell, made faster by her frantic rubbing. Yet, nothing could deny her pleasure, Nadine needing to get off even beyond the cost of her humanity and sex. Besides, the bloating pressure was becoming more insistent, Nadine wanting to relieve it so that she might feel as good as Madison seemed to be. It mattered little that her own ball sack was swelling within, drawing former ovaries down to be repurposed into bloated testicles. What would soon be used to fuel the girthy equine member that was slowly growing from her groin, getting larger as her fingers traced over it. In the moment of lust, it was impossible to find fault in what was happening!
Like Madison before her, Nadine’s ass was making short work of her panties, leaving a growing tail to swish over her puckered equine asshole. As curious as she was about her developing horse cock, Nadine couldn’t help but reach back to touch it, curious about its bestial contours. Her anus had a delightful sensitivity about it, and if she focused, Nadine could swish the hair on her tail over it, making her whicker. It did not escape her notice that her descending horse testicles were being tugged upward to sit under the fat asshole she now possessed. It was hard not to delight in how plump they were, Nadine becoming a surprisingly virile stallion in her own right!
Madison’s horse cock, meanwhile, was stretching toward her belly by now, slapping against the spreading horseflesh as it bobbed up and down. It was nearly ten inches at this point, leaking the pre-seed her new testicles were brewing. Reaching toward her breasts, Madison was drawn to the fact that they were receding, their fatty tissue and sensitivity waning into her barrelling chest. Almost sad for their loss, Madison went to rub at them, finding even the nubs had dissolved into the horsehide that was spreading to coat her. It mattered little as Madison stroked her massive horse cock, shivering as her end starting to approach.
A surprised whicker escaped her lips as something brushed against her cock, and Madison turned, not expecting to see her changing friend so close. Nadine’s hand had reached down to fondle her growing horse’s testicles, making Madison whinny her uncertainty. Not something she would have desired before, Madison found the touch somewhat welcome, even moving her hands off her own cock to allow Nadine to pleasure her instead. The novelty was hot, perhaps more so as it caused her penis to grow toward fifteen inches now. Its equine girth was wildly throbbing as her chest and belly continued to expand to support its new weight.
For her part, Nadine wasn’t sure what was driving her to pleasure her friend like this. Never before had she rubbed such a rod before, and the fact that both she and her friend had developed one left her huffing and panting. Nadine’s cock seemed to be growing from her excitement, forming a flared head with nub-like crowns around it. Its medial ring worked its way against her skin as the thickening foreskin merged with her groin, causing it to slap against her own growing stallion belly. Nadine could almost envision it reaching toward Madison’s own straining hands, desiring the same pleasure.
Her wish was to be granted as Madison got the idea, moving her body so that it was comfortable to jerk each other off. It was not difficult, given the size of their horse meat in tandem with still-expanding bodies. Their forms were largely too small for the penises they possessed, making it hard to think rationally. They were beasts of pleasure in the moment, their cocks powerfully erect and sending waves of ecstasy through their enlarging bodies. Each stroke seemed to pump more meat and muscle into their forms, but such was hardly a concern with their desires to change and grow. If it felt this good, no human thoughts or fears could bring them to stop!
Despite having never done anything like this with each other, the touch of each other’s hands felt natural. Both changing women were nickering and snorting as their fingers became covered in sticky horse pre. Cracks and pops rang out in their twitching ears as chests and bellies barreled, pulling up their shirts and stretching them tautly against their backs and shoulders. Nadine was a little sad when her own breasts began to wane as well, the fat and tissue readily subsumed by an expanding chest. Without even nipples remaining, Nadine soon forgot about them, rather lost in her reality that it simply felt better to be a horse. Even the end result could not dissuade her desire, wanting it to go on forever if it meant her newly formed testicles would eventually be emptied!
Far too massive for human clothing now, the backs of their shirts started to tear violently, horse hide spreading over the bare patches the moment they touched the air. A heavy crack of rotating shoulder blades pushed the sleeves of their shirts to the breaking point, and all they needed to do was roll over a little to be rid of them. Intense itching ran down their thickening necks as coarse hairs erupted from the center, moving down passed their shoulders. Nadine felt it getting in her face as well, blowing upward with lips that were far more flexible than she was expecting. But none of this inconvenience was enough for them to cease jerking each other off. Each was madly snorting their pleasure, and wondering why they hadn’t gotten off yet, as they so desperately needed!
Madison was distracted by the intense pressure in her shoes, feeling her middle toe growing numb and losing the ability to twitch the rest of them. Having seen Nadine’s hooves bursting out of her own footwear, she knew what to expect. Yet, something was appealing about the sound of clopping hooves that made her wish to possess her own. Losing the rest of the digits was undeniably nerve-wracking, but with the pleasure of the change thus far, Madison couldn’t bring herself to want it to stop. As her middle toe tips were covered over with thickening keratin, the pressure soon grew too much for the stitching to handle. She took a brief respite from stroking off her friend to watch its brown contours pushing out for the first time. The force of her stretching heels broke apart the back of the shoes as well, skin itching with fur growth. Warm equine flesh drew in the rest of her toes, something Nadine could no longer twitch as they became nothing within her new anatomy. She was left to perceive the remnant middle toes pushing into her expanding hooves, becoming massive to support her expanding weight. Raising her feet a little, Madison was a little surprised by the heft of them, though the thickened meat and muscle of her hind legs would be more than sufficient to lift them.
Elated by the changes themselves and the sensitivity of their horse cocks, it would not take both girls long to reach their ends. Madison went to call out her need, seemingly forgetting she lost her ability to speak. It didn’t matter in the end, she supposed, her lust clearly portrayed as she stroked off Nadine even faster. Nadine matched her tempo as well, the two of them feeling the tension in their testicles growing past the point of no return. Sharp whinnies of release escaped their increasingly rubbery lips as the two felt their orgasm washing over them. It was nearly impossible to fathom the torrent of semen that such testicles could ejaculate, and the force caused them to both nearly lose consciousness. It was all they could do to keep rubbing each other off, hands and arms coated with horse cum as their pensis unloaded their burden.
By the time they were done, their chests and bellies were soaked, semen soaking into their fur and adding to the equine stink of their forms. Yet, as they came down from an extended release, neither could find fault with the situation. Huffing and panting, memories of the spirits galloping around the room still danced around their minds. What limited mental abilities they possessed wondered if those spirits had entered them. Perhaps something about this site had contained their essence for all these years. Such made little sense, though neither did the changes. Unconcerned, the pair were left to tease each other’s horse cocks, finding they had not entirely deflated after release. It seemed after all these years, the pent-up stallions had more to give. The fact that they were attracted to each other’s male bodies mattered little, both former women finding the novelty rather pleasant. It was impossible to think beyond the now, minds awash in equine hormones.
Still, a panicked whinny from Madison caused Nadine to glimpse a horrific sight. Her grip on Nadine’s cock was waning, and as both women looked on, it was clear her fingers were stiffening. The middle digits were thickening while her ability to move the others was robbed from her. Sharp cracks and pops signaled their loss, and as her wrists stretched, there was soon nothing left of them. In desperation, Madison tried her best to rub the surface of her remaining fingers against Nadine’s cock. It was to be in vain as her arms radically snapped, pulled under her massive chest. All she could do was buck and whinny, fear crossing her eyes at the implication!
With what remaining time she had, Nadine still focused her attention on Madison’s cock, wondering if there was time to bring her once more. It was not to be as her own fingers stiffened, thicker middle digits pushing them to the side as their joints popped apart and dissolved. As Madison’s horse cock flopped onto her belly, Nadine could only stare at her forming hooves in terror. The changes clearly weren’t stopping, and within moments, the pair of them might become horses forever. As good as it felt, they couldn’t want it to go all the way, right? But surely, the stallions that were changing them wanted to recover their bodies in full.
Yet, as the pair of them watched thickening keratin spread over their former middle fingers, there was little they could do to stop it. Like with their feet, heavy nails encased the numb tips of former fingers, filling in to allow them to hold up their new weight. Their size was a little too much for their bodies, upper arms cracking under their chests, and shoulders flattening to leave them streamlined. What remained of their lower arms bunched up with muscle, and with some effort, the two of them were able to stand. As wobbly as they were, it felt more natural to balance on all fours, even as their bodies cracked and popped, muscles swelling under the skin. For the moment, they appeared rather emaciated in comparison to normal stallions. However, with the changes coming as rapidly as they were, they surely would look more natural soon.
Still-human eyes gazed at each other with fear as their stances shifted and their bodies swelled out into equine portions. They couldn’t move much yet, given the newness of their forms and the inability of human minds to operate them. But it was the intensity of their erections that took precedence, slapping against their bellies with desire. It was almost more than they could bear, wanting to get off but having no ability without hands. Frustrated, they whickered their annoyance, stomping forward as they learned to operate their bodies. Thoughts were muddied, jumbled, both former girls scared and horny, and desperate to get their barrings.
Unsteadily stepping forward, Madison’s eyes settled on the door as the light from their flashlight illuminated it, recalling their previous plans to get out of there. There was no guarantee that leaving would reverse the changes or prevent the spirits from taking over them entirely. And since their bodies were already so massive, it would be a struggle to get through the door. But Madison, in her desperation, stepped forward with the singular goal in mind. Her head pushed through the door, though her massive chest and sides were stuck. Swishing her tail and snorting in determination, Madison heard Nadine clopping behind her. With a boost, maybe she could get through, and then…what?
Pulling back for a moment, Madison regarded the door, as though eyeing it to try and approach from a new angle. Yet, there was a part of her repulsed by the clean air in the hall, wanting instead to be once more engulfed by the pungent equine scents in the room. As the rest of Madison’s brown skin turned black with equine hide, a tingling in the back of her mind caused her to pause, instead taking stock of her body. She was massive, powerful, and horny to boot. The stench of their sweaty bodies and cum burned into her being, awakening something feral that she couldn’t resist. It wanted to change, to fuck, and any further thoughts were irrelevant. Even the fact that she losing her human body meant little. There was nothing she could do to stop it, so why not embrace it? And the nagging voice in her mind was telling her to take what she, no, he wanted, consequences be damned!
Nadine, for her part, was able to resist the voice in her own mind, though only just as she moved toward the door herself. Being slightly smaller than Madison’s equine body, she figured she might have a better chance. How she would get down the stairs afterward was another matter, but getting through the door was the first goal. The primal scream within her mind was almost impossible to ignore, though what force she was able to muster pushed her through the entrance. Yet, she still hit the sides with her belly as she whickered her annoyance. She was eager to try again, especially as Madison’s body pressed against her own. Her friend was going to help push her out! Yet, she was shocked when Madison remained there, sticking her nose under Nadine’s flicking tail. And the sensation of hot horse breath on her asshole made her clench, as though desiring to take something within…
Breathing deeply of Nadine’s equine stink, Madison flared his lips, feeling them stretch farther back than he expected. A series of subtle cracks ran through his face as his muzzle stretched a little, allowing more space for his nostrils to sit at their apex. Every inch it grew allowed more scent molecules to waft into his brain. A surge of lust flooded through his being, Madison needing to get off as his horse cock became impossibly turgid. The sweat and stink of horse were all-consuming, and Madison could barely think over the need within his swollen testicles. Even if it doomed him to take this other stallion as his mate, nothing mattered more in the moment!
As tempting as an equine taking an interest in her was, Nadine knew deep down that she needed to resist. Surely, if she changed all the way, she would no longer have the drive to turn back, even if such were still possible. And the first logical step was to get out of here and get help. Backing up to move for the door again, the sensation of hot breath on her donut once more made her shiver, as though waiting to see what would happen next. And as increasingly rubbery lips teased her sensitive leathery flesh, the pressure in her testicles grew to the point she desired nothing else.
Little rational thought remained in her mind as Madison licked and teased Nadine’s backside, loving the sexual scents wafting from it. But the urge in his penis soon grew to the forefront, and without thinking, Madison drew away and raised on Nadine’s back to mount. Nadine did her best to brace herself, the weight almost too much for her to take. Madison’s struggle was far from done, leaking horse pre over Nadine’s pucker and backside, unable to find a mark. As much as they both needed it, their inexperience with their forms made it difficult to the point that they could only whinny their need and frustrations.
Yet, Nadine’s insistence was finally sufficient for her protruding pucker to rub against the flared tip of Madison’s cock. Turgid as it was, Madison managed to shove his member through, causing both former women to grunt and huff their success. It was some effort for Madison to work his way up Nadine’s back, pushing inch after inch of horse cock inside with all the strength he possessed. The size of it was almost too much for Nadine to bear, though she struggled through it, feeling her insides opened up by the sheer girth of stallion meat within her. And as it did, the pressure within teased her prostate, to the point she was sure she could eventually cum from that alone.
As Madison felt his cock reach to the hilt and began to thrust, the tingling of change seemed to accelerate over their sweaty equine forms. In particular, their heads rapidly pushed forward, bones cracking and muscles expanding to keep up with the alterations. It was as though Madison was fucking the stallion into both of them, adding meat and muscle with every thrust. Bodies were heaving with growth, expanding into what their new instincts seemed to dictate. It felt right to change, to grow, and to partake in bestial pleasures as had the beings who had invaded their bodies.
Faces were getting massive all the while, heavy on thickened necks as their entire skulls expanded several times the size humanly imaginable. Noses stuck out in front of their faces, easy to see as their eyes were forced around to adjust to their new muzzles. Longer rostrums breathed in heavily of their equine musk, Nadine feeling her thick rod slapping against her belly while Madison thrust faster than humanly possible. The skin around it turned rubbery with velvet hairs, stretching over expansive gums that drew back to drink in as much equine musk as they could. The force of growth pushed their incisors to the front, turning them thick and blocky and sitting in splotchy gums. It was strange, though, as their skulls shifted toward equine proportions, their cries of lust and ecstasy sounded proper to their twitching ears.
Both whinnied their passions as Madison’s front hooves squeezed tightly against Nadine’s flanks, pumping her for all his stallion self was worth. The pressure helped Nadine’s own horse cock slap against her belly, pre-cum flying everywhere as her pleasure grew. The force of an equine phallus against her newly-formed prostate was surely enough for her to cum. Flexible rectal muscles gripped every inch of the invasive cock, wanting to draw all Madison had to give. In the heat of the moment, nothing mattered more than the release to come. Their humanity, even their femininity, was easily discarded, the desire to escape and change back the furthest thing from their minds.
As widening equine eyes took in the world from a new perspective, both beasts blinked for a moment, as though confused at their surroundings. Some instinct saw the room as far removed from the pastures and barns that their budding minds seemed to crave. Eyesight dimmed as colors faded, triggering something within their minds, as though the stallion spirits were waking to the world once more. And with that, there will be little to hold them back, becoming those beasts more desirable if they came with such poignant pleasures!
All the while, Madison continued to thrust into his mate, thick horse cock squeezed expertly by Nadine’s flexible rectal muscles. It wouldn’t take him long to finish as the pressure grew well beyond what he was able to handle. It almost seemed like an afterthought that his brain was shrinking. An equine skull was compressing on its edges and forcing ridges and crevasses to fade away, and with it, human thoughts and memories. Nothing remained to care, however, as another presence seeped into his mind, memories of foals and fields and farms replacing beds and childhood and schooling and friends. It was as though his shifting brain was better for the presence to be reborn. Fading human thoughts wished to allow that simplistic beast to take over, to succumb to desires that he could achieve in the here and now.
The last human thought fled his mind the moment his square-shaped teeth bit down on Nadine’s neck, claiming her. Any fragments of his identity, the memory of his friend, or the circumstances that changed them were washed away within his straining testicles. Soon, the stallion’s cock blew thick wads of jism into his male mate. He stopped thrusting, rather holding his stance and forcing his submissive stallion to take his load, as though pent up from years of void and darkness. No recollection of how he had gotten here came to mind, though it mattered little in the moment of heat and passion. Grip on his mate’s nape, the other stallion whinnied, as he, too, lost control over his stallion rod. Slapping against his belly, he eagerly shot his load over the floor beneath. His body was rocked by the force of the larger male on his back, though he held firm, relishing the pleasure. Gratefully, he pulled back his lips to drink in the pungent aroma from their combined sweat and male musk.
Getting down off his stallion mate, the massive Morgan horse sniffed around, confused about his surroundings. No longer did he detect the acrid scent of smoke or the pain of heat all around. He was here, safe, among only the scents of his musk and his mate. Rubbing against the other horse, the two of them nickered and lipped each other, hooves clopping in the confined space. Such should have been alarming, especially in the dark with no obvious exit. But given the last faded memories in his mind, the heat and flames followed by an eternal dark, all he could do was feel, at last, an immense sense of welcomed peace…

It was a widespread story on campus when a pair of stallions were found in the abandoned dorm, heard stomping around, and checked on by security. How they had gotten there was a mystery, and even the promise of money for information was not enough to bring to light who was responsible. Surely, it had to be part of a prank, but with no culprits and no sign of any missing animals from nearby farms, eventually, the college board had to leave it be. Like every major event on campus, it was soon forgotten in the face of another, and the students went back to their lives without giving it further thought.
Without a home to return them to, the stallions were eventually brought to a local stud farm, where campus staff were assured they would be well cared for. However, despite their impressive stature and presence, it was quickly clear they had no interest in mares. They were certainly amorous for each other, their cocks coming to bear at least once a day in the presence of the other. Their behavior was rather fascinating, each taking turns with the other and regarding each like a pair of bonded mates. With the way they frequently rubbed and nipped at each other, no one had the heart to part them. Thus, they were allowed to live together, lusting for each other with no regard for their past, simply relishing their rebirth from the stallion spirits that had inhabited the formerly human vessels…
