It was a sunny summer day on the horse ranch. Kayla, a stable hand, was tasked with brushing down the horses. It wasn’t a bad job, but long and boring since there were 20 horses on the ranch and she was only one to take care of them.
She brushed her way through the first 19 horses, saving her favorite for last. It was a pure black Morgan stud named Warrior. He was an absolutely stunning beast. His hid shined like no other in the bright summer sun, his well defined muscles on display. Kayla took a liking to the stallion based off his personality. He was so gentle and easy around her, despite being a breeding stud and having mares around him all day.
Kayla started on Warrior’s neck, brushing along his short, black fur. From there, she worked around his chest, front legs, sides, belly, rear flanks, his large butt, and back down the other side. Once Kayla finished with his body, she moved to his mane and tail. They were long and majestic, but always needed to be brushed out. She started on his mane and once done with that, got to work on his tail. The brush slid through the long, coarse, black hair with ease until it unexpectedly caught a rare not, abruptly hooking on Warrior’s tail and pulling it.
“Oops! Sorry bud!” Kayla said in a gentle voice, but as she looked up, she saw every person’s worst nightmare: a horse hoof head in her direction!
Kayla had no time to react as it struck her in the side of the head, knocking her unconscious.

When Kayla awoke, it was dark. She felt something different... very different... she struggled to get to her feet and stumbled through the barn, and by feeling the walls to head the way, she eventually found her way to the tack room which had a large mirror hanging on the wall. Kayla blindly felt for the light switch and turned it on.
Her jaw dropped. Now standing in the mirror was a naked centauress. It was her, Kayla, with Warrior’s body from her waist down. And not only did she have Warrior’s body on her lower half, but her own upper body changed quite dramatically as well. Her little to be desired gut had disappeared, leaving her stomach fit and trim. The fat had appeared to have relocated... to her chest. Her B cup breasts were now a least E cups. Kayla’s pudgy, acne covered face also seemed to have changed, now appearing slim and blemish-free. Finally, her dirty blonde, greasy looking hair was now beautiful and flowing, like a mane.
Kayla starred in disbelief at the reflection in the mirror for a good solid five minutes before realizing it truly was the new her. She was speechless. Kayla flicked her new tail and finally snapped out of her daze. She lifted her hands to her large breasts and gave them a light squeeze before sliding her hands down her flat stomach to the spot were her two bodies met each other, petting her new furry half.
“This is real... this is so real... how?...” she said, still starring. “And poor Warrior... I am now him- Him!!!”
Kayla quickly turned her large lower half sideways and lifted her hind leg, revealing a large dangling set of black horse testicles nestled behind a rather plump looking fur covered sheath. Kayla then turned a bit more so that her large rump was facing the mirror and lifted her long, black tail high and to the side. All she saw was a very large, fat, black, horse, donut-shaped anus situated between her enormous fur covered buttcheeks.
“I’m a boy now!” Kayla cried out.
A tingling sensation began to build in her rear crotch area as she began to cry. Kayla turned back sideways and lifted her rear leg again. She saw exactly what she expected: a large black and pink mottled horsecock, about 22 inches long, hanging nearly fully erect from her sheath.
“Oh my god! Gross!!!” Kayla screamed, in tears.
