“So, John. If you let me experiment on you, I’ll make sure you have a wonderful experience as a horse herm. I’ll give you a luxurious life full of sex and pleasure. Or… I could send you to another reality, one without any of us.” Jennifer said through the speaker.
“There’s another reality?” John asked.
“Yes, full of humans, with no equines.” Jennifer said.
John’s brow furrowed. Maybe it was because his dick was painfully hard, but he no longer felt an obligation to “preserve” humanity, especially since he just found out that a whole other reality existed.
“Ah, fuck it. Do what you’re gonna do. I wanna cum.” John said.
“Are you sure? I don’t think I can reverse any of these changes. Once you’re an equine, you’re one forever.” Jennifer said.
“Do it. Before I change my mind. Please.” John replied.
“Ok. We’ll be monitoring your changes in our booth.” Jennifer replied, pressing another button.
Another gas filled the room. John inhaled it as he began to change, pleasure building within his nude body.
John’s body hair immediately disappeared. He watched in awe as it receded into his skin; his bones began to crack, though not painfully, as his shoulders and waist pulled in and his hips pushed out. His hands and feet shrunk as his overall shape became distinctly feminine - though he grew from 5’11 to 6’5.
John felt so much pleasure that he began grunting; as his body feminized, however, his Adam’s apple pushed in, and his masculine grunts became feminine shrieks.
Jennifer, meanwhile, was in her control booth with Cynthia and Zoe, following along to Candi’s instructions and pushing very specific buttons to change John. Jennifer smiled; despite the lack of equine features, John was coming along nicely, resembling a femboy instead of the gruff man he’d been before. Eleanor, meanwhile, was being milked, her equine fluids being used to power the machine. Jennifer decided to have John enter phase two in the transformation.
John moaned as his mind filled with horse herms having sex; he began humping at the air, desperate to cum, pushing his widened hips off of the platform he was strapped to. With each motion, his rear began to expand, lessening the distance his now impressive bubble butt took to hit the platform. As his rear continued to grow, John’s anus turned equine, and between his anus and balls, an equine vagina opened up. John began to think of himself a woman, a new name popping into her head: Julia.
Julia’s mind began to warp further. Instead of horse herms just having sex, she imagined one very specific horse herm; a stripper and escort on the level of equine fame as Ling Colt or Sadie Suxxx, a porn star who equines held in as high esteem as humans did the most famous actors and musicians.
Unbeknownst to her, near her anus and vagina, the platform opened up, an equine dildo and massive butt plug pushing out. As she finished her final strut, both were shoved into her orifices, hard, Julia let out a shriek of pure pleasure. The two toys vibrated and pulsed as they shoved themselves in and out of Julia’s new equine holes, pleasure building inside of her body as her brain was taken over by the urgency to cum she was now filled with.
Jennifer smiled to herself. Time for the final phase.
More gas filled the room. Julia’s brunette hair cascaded down her back as it thickened and softened up; instead of the buzzcut John had sported, Julia’s long, beautiful hair would reach her impressive rear. Julia’s skin became impossibly soft and supple as her natural body odor morphed into the equine musk she’d been so thoroughly enjoying.
Julia’s face became extremely feminine as permanent makeup covered it. Her lips plumped up, becoming impressive DSLs as her nose shrunk and her cheek bones became more prominent. There’d be no mistaking her for a man now, especially as a pair of bowling ball sized breasts filled with milk rapidly grew on her chest. She gained some muscle, though not too visible, to carry around her new assets, finishing with a sexy six pack on her toned waist.
Her tiny nipples morphed into thumb sized teats, ready to spray her corrupting breast milk at any point. Julia desperately tried to free herself from her restraints; even the slightly cooler air in the chamber hitting her nipples was setting her off; she never would’ve imagined pleasure of this magnitude existed.
Julia’s ears moved to the top of her head, elongating and gaining fur that matched her brunette hair, becoming horse ears. A matching tail grew above her rear, which had finished growing and was equally as impressive as her massive breasts.
Finally, Julia’s cock began to morph and change. The neglected 5 inch human cock near instantly changed into a 20 inch long equine cock, covered in whispy white fur. Julia felt like her mind was going to break as her huge tits shot milk, her cock finally cumming after 200 long days, her new equine vagina spraying musk-scented cum all throughout the test chamber…
Julia moaned; it felt like she was having an out of body experience. She pictured herself in a hallway that represented her mind, walking up and down, watching as memories morphed. She knew exactly how equines worked, as if she’d been one all along. Names of famous human celebrities disappeared, replaced with slutty equine porn stars, escorts, and strippers. How to properly milk herself. Shopping for slutty clothes. Buying expensive dildos and sex toys. And all the sex she had. One thing stuck out to her, though: She realized that SHE was the famous equine she’d been picturing. Julia Cummers, the beloved celebrity escort, the world’s most well known whore - no longer was she a research scientist. She realized her hobbies were changing, from shooting at a range to getting fucked by several equines at once, from cooking to sucking as many horse cocks as possible. And she remembered getting married to Jennifer… her happiest memory, the equine world’s biggest slut becoming married to their goddess. Even though she had her old memories, these felt so much… better. She happily embraced her new life, and with a shot of light, woke up.
Finally, Julia’s orgasm subsided as her restraints disappeared. The door opened and Jennifer arrived.
“Well, my love? Our kingdom isn’t going to rule itself.” Jennifer said, with a sultry smile, extending her hand.
Julia stood up, still not quite used to her new body, and took her wife’s hand.
