Steph let out a loud sigh, the third within the past five minutes. It didn’t help that she was already forced to breathe through her mouth. The air was permeated with the stench of a barn from the horse that had been led inside and left there. She, along with this year’s other ΑΔΠ sorority pledges, Jordan and Maddy, were forced to deal with the disgusting task of cleaning up after that bitch’s horrible prank. What was her name, Katie? It was bad enough that she couldn’t tolerate not being accepted into the sorority, but to bring an actual horse here? How she had managed that was anyone’s guess. It would have been impressive had they not been given the task of dealing with the horse’s leavings. 

Steph cursed the girl as she continued picking away at her work. Katie still hasn’t been found, and their sorority head Deanna didn’t have the foresight to keep her application. The worst part was that Ashley and Nicole, their sorority sisters, had gone missing as well. Were they in on the prank? They would likely be kicked out of the sorority for their part in antagonizing the failed pledge.  

Jordan was having an easier time with the work. She had grown up on a farm, so the scents of horses didn’t bother her as much. Still, she resented how she and Steph were doing most of the work themselves. Maddie spent all of her time whining or texting on her phone, obviously too afraid to get dirty. 

As Steph worked, a strange slight on the floor caught her eye. It looked like an old book sticking out from the edge of the couch. She leaned over to pick it up, curiosity getting the better of her. Anything was better than shoving horse shit, after all. Carefully, she flipped through the worn dusty pages, studying the strange text, written in a language she didn’t recognize. The section she was looking at seemed to have pictures of animals, including a horse proudly displaying its massive dong underneath. Steph felt appalled. It was just like the animal she was forced to clean up after!

 The next page held a picture of a donkey that was every bit as male as the horse. The words underneath the diagram were in that same unreadable text. Maddie was a language major, so Steph figured maybe she would be able to read it. She tried her best to mumble out the text, thinking if Maddie heard it she might know what it said. 

With her nose deep in the book, Steph hardly noticed where she was going. She cried out suddenly as she slipped on the mess on the floor, causing her to fling the book into the air. In her panic, she didn’t even see the bright light emanating from the thick tome, even as it lanced upward and struck the ceiling light, reflecting off the glass surface and striking everyone in the room. 

Steph felt something hot touch her face as she lay on her back, looking up at the glowing ball of light above her. It was far brighter than the light in the room should have been. Did she have a concussion? 

Both Jordan and Maddie raised their hands to shield their eyes from the brilliant glow. Something burned against the skin of their hands for a moment before it seemed to fade. They blinked a few times, wondering what it was that had made the glow, having not seen the book. 

Steph, meanwhile, felt something itching at her face as she struggled to get her bearings. Coughing, she began to realize that her mouth felt rubbery and stiff, as though she had a fat lip. Worse, her nose felt strange, wide, and thick, which intensified the offensive stench of horse from the room. Yet somehow it didn’t smell as bad as before. It had a quality to it that reminded her of…home? 

By now, that itching sensation had spread up her head, a coarse, rough sensation meeting her fingers as she tried to scratch at it. An odd tingling feeling had begun to spread over her ears as well, intensifying into a painful stretching sensation that left them sore. Her entire jaw began to ache too, the bones feeling raw as if she was fresh out of dental surgery

Just now coming to their senses, Maddie and Jordan got to their friend to help her up, only to see the hilarious changes to her visage. Steph’s face was protruding into a muzzle, her ears sticking out the top of her head as grey fur slowly spread across her face. She looked inhuman, reminding the two of them of the horse that had been present only hours ago. Only her features more closely resembled… 

Despite the horror of her changing face, Jordan couldn’t help but laugh. “You look like a jackass!” Jordan yelled, giggling uncontrollably at the sight. She didn’t know if it was makeup or what, but the asinine visage on her friend was just too much. Maddie also broke down at the sight, holding her sides with her somewhat stiff hands… 

“WWHHHHAAAAWWW are you taAAAWWWWking about?” Steph began, then paused. What was wrong with her voice?

“Did that cAAAWWWWWm out of mEEEHHHHAAAWWW!?” She yelled, unable to keep the donkey inflections out of her speech.

Maddie and Jordan were nearly on the floor with laughter at this point. They didn’t even seem to care that their friend had the face of an ass, it was too damn funny! 

They were giggling so hard, in fact, they were barely aware that their fingers were shrinking, their middle digits thickening as it got covered with one large keratin nail. The sensations were only registered as a numbness akin to having their fingers falling asleep, although soon, the digits were entirely absent. 

Steph meanwhile had gotten up and started rubbing her face, shocked to feel her massive black nostrils and protruding muzzle. She looked around for the mirror that the sorority kept in the common area, afraid of what she might find but needing to know all the same. To her horror, she was met with the face of a jackass staring back at her. Her proto muzzle was still extending outwards, but the rest of her facial features were very much that of a donkey’s. She blinked a few times, finding it hard to see as her eyes began to rotate to the sides of her head, straining against their sockets as they grew larger. Even her hair had begun to change, getting short and bristly as it ran all the way down her neck.

“This can’t bbeeHHHEEEHHAAAAWWW! HHEEEHHHAAAW!” She brayed, unable to make human sounds any longer. She could only watch as her head continued to grow out into jackass proportions, her entire body beginning to ache with change.  

Maddie and Jordan stopped their infectious laughter and looked up in horror to see Steph’s changes weren’t stopping. In fact, from her tightening clothes and spreading fur, it seemed she might be becoming a full ass. But that was impossible, wasn’t it?

“Steph, are you alright? Speak to mEEEEHHAAWWWW!” Jordan brayed with horror as her voice began to deepen towards an equine inflection as Steph’s had. But as she put her hands to her face to try and hide the noise she made, she nearly screamed. Most of her fingers had seemingly vanished, with the ones left thickening to the size of her hand. A large, dark brown nail began to encase her remaining digits, making them look like the hooves of a jackass!

“Jordan, h-help mmEEEEHHHAAAWWW!” Maddie yelled as she fell forward onto her hoof hands. Jordan could only stare as her friend’s dark skin became peppered with short brown hairs that spread up under her shirt. Maddie had her back to Jordan, the other girl staring in horror at the bulge pressing out of Maddie’s panties. Within moments, a large tasseled tail began ripping out of the seat of Maddie’s pants. 

To her own horror, Jordan could feel her feet start to get tight in her shoes as they shared the same fate as her hands. She could feel the middle toe ballooning out with a thick heavy nail as her heels began to tug at the weak leather. Her expanding hoof exploded out of her shoe as her ankles stretched so high she was thrown off balance. With a yelp she fell forward, her new hoof hands hitting the floor with a loud clack. A deep groan escaped her lips as her hips began to flatten and spine became realigned. With a sickening crrrunch, her four-legged position became much more comfortable.

Steph, meanwhile, continued braying in panic as her chest expanded, pressing tightly against her sweatshirt and ripping the fabric. Previously perky breasts shrank and left nothing but residual nipples as her chest barreled out and shoulders rotated forward and flattened into her growing flanks. Her wrists started to ache as her nails became covered with thick keratin, rapidly becoming hooves. 

How the fuck was this happening to them? A few moments ago they were normal college girls, but now they were each over halfway changed into simple farm beasts! It made no sense!

Steph then saw something glowing out of the corner of her eye. It was hard to focus with equine eyes, but it seemed to be coming from the book she had been reading. Could it be some sort of spellbook? If so, was there a way to change them back? Yet, Steph was painfully aware it didn’t matter now. None of them had hands to pick up the book, and she no longer could speak with a human voice anymore!

A tingling in Steph’s groin distracted her from her misery. Her clit started to expand rapidly, pushing out of her folds and pressed against the edges of her panties. In horror, she could feel something leaking fluid within their confines. She moaned as something inside her began to swell and push at her vaginal opening. Something thick and heavy began to fall into her panties as her ballooning ass stretched against the fabric. A resounding rip echoed in the room as the thing in her crotch tore its way free. Standing proud for all to see was a mottled pink and black shaft. Underneath her closing vaginal lips extended a thick fleshy sack that was steadily filling with something round and heavy. 

“Steph! You have a cAAWWWWWWk!” Jordan yelled, seeing the massive penis tear out of her roommate’s pants and swing back and forth. A fleshy, furry sheath began to pull from the head and attach it to Steph’s increasingly bulbous gut. The poor girl brayed and bucked in panic from its weight as the remnants of her human vagina closed up and disappeared completely. 

Jordan was drawn to a similar sound as Maddie’s own thick equine cock torn out of her panties and began dribbling foul-smelling precum all over the floor. Not only were they changing into asses, but they were getting their gender changed as well! Jordan was not to be spared this fate either as a similar sensation began welling up from her own sex, seemingly a prelude to her own donkey cock.

Steph’s changes were almost complete. An audible tear from her pants signaled that her ass was ballooning out, filling with fat and fur as her anus shifted upwards to accommodate the space that her massive balls were now taking up. They jiggled back and forth as the massive black orbs swelled with equine seed. A tail erupted out of her spine, stretching back and forming a furry tassel at the end. Her shoes were torn to shreds by her massive hooves. There were audible cracks all over her body as she swelled out, veins bulging against her human skin as it got replaced with equine hide and fur. 

Steph’s thoughts began to drift as her skull cracked and compressed on her brain, reducing the area that her human organ could occupy. The change soon eliminated all the thoughts unnecessary to her asinine body. The fear and worry of her transformation began to evaporate, replaced with simpler needs like hunger and lust. At last, the spell was completed and the new jack brayed with impatience, upset at the lack of jennies in the area to breed. 

Jordan watched in horror as Steph’s tail lifted and proceeded to add to the pungent smells in the room. There seemed to be no modesty left in her friend, not a single trace of her human thoughts. Jordan’s gaze shifted over at Maddie, seeing her bray in terror as her muzzle started to stretch out and her forehead started to shrink. Her own massive donkey ass tore out of her pants, complete with a thick tasseled tail as the fur began to spread up her thickening neck. 

“What the fuck!” A girl’s voice yelled, followed by the thundering of footsteps. Jordan thought she recognized Deanna and felt a blush of shame as her own tail lifted and her puckered anus added to the heavy barnyard stench. She had no control over her bodily functions! Her last moment of humanity was to look into the eyes of her sorority head while she could do nothing but act as a simple beast. 

Jordan could see her nose in front of her eyes now, smell the terrible stench of her breath as her tongue changed. Her gums became mottled and blotched to contain thick, yellowed equine slabs. Pointed ears were already long atop her head, and massive, brown orbs were rotating to the sides of her visage to accommodate her ever-expanding jaw. Her forehead began to slope, and already it was getting harder to think, harder to remember why she had been so worried before now. 

With a bray of surprise, Jordan could feel something goose her puckered, dirty anus as the donkey that had once been Maddie started sniffing around her backside. Some instinct told her to raise her tail as the fully formed jackass reared atop her back, planting his hooves along her bulging flanks. A flattened cock tip pressed against her anus, and she leaned back against it, feeling a pleasurable sensation on her prostate as she was filled. Her last human thoughts faded as the horny jack thrust into her and spilled a load of thick spunk all over her, now him. 

Deanna, Emily, and Janice could hardly believe what they’d just seen with their own eyes. There was no way their sorority sisters had been reduced to common jackasses. It made no sense! Denna wondered if their coffee had been spiked. The trio was so stunned they barely realized the bright light on the ceiling that reacted to their presence and bathed them in a warm beam. 

“WWAAHHHHAAAWW!” Deanna yelled as her nose started to blacken and press out from her face. She reached up to touch it but was shocked to find her fingers no longer worked. Her middle finger was covered in a hard nail that couldn’t even detect the darkening hide, while the rest had been reduced to nothing. Ears stretched up on her head to match the asses in the room with them. An equine grunt escaped her lips as her back started to crack. Suddenly off-balance, she fell onto her developing front hooves as her body started to rip out of her blouse. Perhaps worse of all, she could feel something massive growing from her crotch, something strange that leaked fluid all over her panties and caused her cheeks to flush with arousal. 

Emily tried to run but slipped on the floor and fell onto her human hands. Trying to get up again was futile as a crack from her back made the position permanent. A look back revealed her growing mane bristled up her thickening neck as her massive thick tail tore its way from the back of her pants. Expensive shoes split without regard with the development of shiny black donkey hooves. A whicker escaped her lips as her equine cock grew massive in her panties. One of the already fully-formed jacks began sniffing at her ass, looking for something to rut in and spill his seed. Emily brayed in protest, but soon the brays turned to ones of pleasure as her mind began to wane and she raised the tail for her mate. 

Meanwhile, Janice looked on with rapt attention, feeling her new cock getting harder in her pants with her human sensibilities. Unlike the others, the idea of transformation was actually rather arousing. Though she’d never have wanted it to happen in real life, she couldn’t deny how wonderful it was to rub her still human fingers over the flesh of her growing cock tip. Her other hand played over her new ears and muzzle, braying in ecstasy as her cock shot a load of cum into her pants. Growing asinine bulk ripped them off and she fell down onto all fours, eager to join her new herd mates. 

Soon the six asses were fucking, braying, and slowly making their way outside to look for something tasty to eat. None recalled any of their human memories, only confusion at the strange sights and smells of the enclosed house. A few raised tails and unfurled cocks made the scents seem more comfortable as the sweaty, smelly donkeys went about their day in asinine bliss.  

******

Brad, Zach, and Troy could almost smell the stench of a barn before being greeted to the sounds of brays and whickers coming from the house. Maddie had texted Troy about the horse that had been let inside by one of the rejected pledges, and the boys wanted to head over to see it for themselves. 

Judging from the scents wafting out of the house, it seemed like an entire barn had been let into the sorority. They stared in shock at a small herd of donkeys gathered outside the house, standing around and grazing on the lawn. They all seemed to be males, and the trio was disgusted by the sight of one of the massively erect asses trying to mount one of the others while it continued mindlessly grazing. 

“Hey, Deanna?” Brad yelled, wondering what the hell was going on. He ran to the door, stunned as a flash of light hit his face. A sudden sneeze hit him through nostrils which were suddenly growing massive and black. An itching encroached all over his face as his back began to crack and ache. Something massive started poking out from the back of his pants and began moving on its own accord.

“What that FFAAAAAACCCCKKKK! HHHEEEHHHHHAAAAAWWWWW!” Brad brayed, no longer able to talk as his neck thickened and mouth pressed outward into an equine muzzle.

Zack and Troy ran to help him, wondering what was happening with their buddy. Unbeknownst to them, it was the light from the spell still lingering in the room that had caused his changes. And by running to his side, they’d let themselves become exposed as the warmth of the spell raced over them both. 

Troy looked down to see his already dark skin becoming covered in grey donkey hide. A deep moan escaped his rubbery lips when his changed hoof-hands could no longer pull his increasingly tight clothes off his body. Zach felt sick as his innards changed and his massive puckered ass ripped out from the back of his pants. Both men fell to the ground, braying as the position became more comfortable. 

Brad felt something moist where his cock had been, as though he was aroused. The one benefit to the change, he was sure he would be growing the massive equine phallus that the other donkeys now had. Yet, instead, he could feel his cock shriveling, and something opening up underneath him, taking his balls in with it. Confusion raced through his mind until he found himself at eye level with Zach’s backside. Under his massive puckered ass and tail was the beginning of a wide, leathery opening, taking with it the last of Zach’s cock. The tiny shaft kept shrinking until it was nothing more than a bulb of flesh sticking out of a clef nestled in a much larger opening that looked like a vagina. Zach had become a chick! And so had Brad if the sensations were any indication. 

Brad grunted in embarrassment as a massive wet nose began sniffing at his nethers. In response,  his ass tore apart his pants and underwear, exposing his new donkey cunt. He couldn’t want this, yet a part of his shrinking mind kept him still as he pissed himself. The jack seemed not to mind as he started lapping at Brad’s folds before raising himself up on Brad’s back. Brad wanted to yell but could only bray as his new cunt was penetrated by the massive donkey dong. Yet the waves of pleasure racing through his flanks were like nothing the human male had ever felt. His eyes fluttered shut as his skull contracted and thoughts began to drift to simpler things like breeding and grazing. 

Zach and Troy were not far behind as they eagerly raised their tails to their new jacks, the need to breed overriding the human fears pervading their thoughts. They were literally fucked into jennies as their udders formed and bounced against the weighty black balls of the jacks upon them. Soon, the small herd had been expanded to nine, with the promise of foals on the way after several months if the jacks had properly done their jobs!

******

The sight of a yard full of donkeys did not go unnoticed by the community. One of their neighbors called the authorities, who were more than a little annoyed to have to make the trip once more. Two squad cars came this time, three male officers and one female officer, in case the residents of the ΑΔΠ sorority were to be arrested for repeated disturbance violations. They didn’t want it to come to that; these were college kids, after all. But this was getting out of hand! 

They were not prepared for the sight of a small herd of donkeys that had spilled onto the streets. Several were breeding while the others grazed. What sort of sick twisted situation had occurred? 

All four officers entered the premises after calling for animal control to collect the beasts of burden. And upon doing so, the still-present spell did its work. The officers panicked as their belts were torn off their massive bodies and their walkies fell from their hooves amidst their brays of protests. The men shuddered in horror as their male-hoods retracted to form the beginnings of a jennies’ sex, while the woman felt stirrings from her new donkey cock at the prospect of three needy jennies to mate. 

*******

“This is Stacy Branson reporting for CJTV news. We’re live at ΑΔΠ sorority, where today, several students, officers, and animal control personnel have gone missing as a result of an out-of-control prank. We are entering the house now, which seems to have been taken over by a herd of donkeys…oh…Oh HHAAWWWWW!” She brayed as her massive donkey cock began tearing out of the fabric of her blouse. 

The camera remained trained on her for a few moments until she fell to the ground with a crash, getting a shot of the cameraman’s hooves and growing tail. He backed up, apparently crunching the camera with his increasing bulk as the image went black.

An elderly woman had been watching the news feed and almost laughed at the sight of even more humans becoming asses. She shook her head at the mortals’ stupidity. Still, it was nice to be able to watch the fruits of her labor for once. 

Though her house was in disrepair from the outside, the inside was rather spacious and modern. She preferred to keep her glamor up to prevent humans from disturbing her affairs. Still, someone foolish enough to enter would be able to interact with the objects in the house. More specifically, her family’s spellbook, in the case of that foolish girl. 

So many were changed in such a short time. Serves them right for trying to meddle in her affairs, she thought. They were no smarter than the dumb beasts they’d turned themselves into. The section that the girl had ended up poking around in was filled with curses, turning people into beasts of the opposite gender for an even more horrific fate before their minds degraded. All in all, it was a fitting punishment for a thief like her.

The woman briefly considered going out to retrieve her book, and maybe to eventually turn the stupid humans back from their bestial forms. Especially the two girls that had become male flies. They wouldn’t live much longer in their new bodies, after all. She could enter the space unharmed, of course, impervious to her own magic. 

At the very least, she could undo the spell that had settled over the house lest her entire neighborhood become overrun with smelly jackasses. But what good would it do to change the humans back now? A surplus of beasts would help the local farms. And it would serve as a reminder that curses were indeed real, and be a fitting fate for anyone brave or foolish enough to enter the space.
