A reality altering wave passed through the girls dormitory that Minerva and Phoebe had frequented when they were still human. All of the students they'd fucked, many of whom had felt confused by their irresistible trysts with transwomen when they'd only ever been attracted to boys, suddenly had memories of fucking the now equine pair. Those who were asleep experienced deliciously wet dreams as their minds were re-written to accept the change, while those who were awake found themselves overwhelmed with perverted thoughts as their clothes changed to match their new personalities.
Tiffany, who'd been trying to study late to distract herself from the guilt of cheating on her boyfriend with Minerva, stretched her arms and yawned. Her t-shirt shrank into a pink tube top and only the metal underwire remained from her vanished bra, quickly condensing into steel studs that pierced her nipples. She hissed as she remembered getting them done for Minerva.
Her roommate, Riley, started moaning in her sleep, distracting Tiffany from her study. She glanced over at the girl she'd shared many late nights discussing English poetry with and shook her head as those memories were replaced with them mutually masturbating to their secret, perverse desire to fuck equines.
She chuckled. The slut had probably fallen asleep with a dildo lodged in her snatch again. Riley was always horny and the smell of her juicy cunt permeated the air even when she was away at classes. It was one of the many, delightful side effects of the tablets that appeared on her dresser.
Around the room various items that had been prepared by Cynthia popped into existence. Pheromone altering body sprays, mutagenic lubricants, and equine HRT tablets littered the room. It was the combination of these items that had both enabled the girls to take equine dick and not become equines themselves, although they were no longer exactly human either.
Tiffany switched her attention back to her computer. She was already late on an assignment, but she promised herself just one more video first. She hit play on a Sadie Suxxx blowbang and squeezed her thighs around her hand as she fisted herself to the sight of Sadie's gorgeous bimbo face getting lost beneath five mottled shafts. The porn didn't change her, but it did seal the changes from the reality altering wave that had hit her just moments earlier, permanently warping her mind into a sex-obsessed, porn addicted pervert.

Riley stretched her stiff limbs as the dawn light woke her and tossed aside the bedsheets. The extra weight on her chest didn't trouble her. Or at least, not in the way it should. She clearly remembered her itty bitty titties growing to the size of cantaloupes thanks to the equine HRT tablets, though she was still getting used to her new size.
She giggled when she caught sight of Tiffany sleeping at her desk. The slut had her tube top wrapped around her waist and her hand between her thighs, with her head rolled back as she snored. On her laptop Sadie Suxxx was getting pile driven by a muscular herm, and the sight of the porn immediately solidified her own changes from the reality warp that occurred during the night.
She snuck behind her friend and tugged on her piercings to wake her up. Tiffany yelped.
'Ouch, you fucking whore! I only just got those done!'
'I know you like it really,' said Riley, but she let go of the studs. 'Don't forget I was there when Minerva turned you out as a painslut.'
'Then you also heard what she said. Mistress can do what she wants with her pets. Humans can't.'
'Sorry babes. Let me make it up to you.'
Riley bent forward to dangle her tits in Tiffany's face and her friend latched on to a nipple. She sighed as her milk let down and her free tit dripped to the floor as her other fed her best friend.
There was a knock on the door.
'Come in!' shouted Riley.
One of Minerva's other conquests entered. Formerly a traditional looking cheerleader, her head was shaved on one side and there were several piercings in her ears and nose. She wore black eye-liner that was rumoured to be tattooed on. Around her neck was a black collar with the word cumslut adorned in silver letters. She didn't bother with a top, leaving her huge but firm tits on full display with their webbing tattoos centred around her wide areolas. She had another piercing through her naval, and below that were the words "EQUINE WHORE" tattooed in script.
A wide studded belt, ripped fishnets, and leather platform boots completed the look.
'Are you sluts skipping classes again?'
