Humantaur

Leshawna turned her attention to where the dart hit her and noticed a tingling in her rear. Followed by a strange sensation that she could only describe as her booty sticking out against her will. "I knew it! You are making my ass fatter!"

"Huh, I guess it was butt expansion. I could sworn we picked something else," admitted Blaineley.

"Hang on, it's not getting bigger," Beth pointed out.

"Is it getting longer?" finished Lindsay.

Leshawna's ass had been called a lot of things but she's never anyone say that she had a long butt. However, it seemed to be a fitting description seeing as it looked like she stuffed a brown boogie board down the back of her pants. Unable to take the strain, the back of her pants ripped down the crack and exposed Leshawna's peculiar mutation. What could only be described as a bar of flesh was sprouting from backside. With her butt cheeks at the end and two lumps on either side of the back. A couple of the contestants looked away from the brown buttocks as Leshawna started to lose her balance. She fell to her knees and Blaineley backed away to a safe distance.

The lumps elongated downward and thickened with mass. Taking the shape of Leshawna's legs as feet formed at the base. The bar extending from her began to resemble her back and at the end of it all was her signature shelf. "What the fuck did y'all do to me?!"

"O-M-G!" Squealed Sierra. "You're a humantaur!"

"A what-taur?" Blaineley asked.

"A humantaur! They're like a centaur but instead of a lower horse half they have a second body growing out of them."

"How do you know this?" Gwen questioned.

"I've spent a lot of time browsing the internet for fan art of the show. You wouldn't believe the kind of things I've seen you get turned into."

"Just tell me when it's over!" Leshawna wailed.

Her new set of feet touched the ground and her second torso finished filling out. Just as plump and full-figured as her original. The tingling stopped and Leshawna dared to open her eyes. Slowly, she rose off the ground and looked herself over. Tentatively testing her hind legs. It freaked her out when they twitched and flexed. It was so surreal it didn't even occur to her that her bare ass was on full display to the cameras and the other contestants.

"There you go, ladies and gentlemen! Give it up for Leshawna the Humantaur!" spoke Blaineley.

Leshawna jumped when the crowd clapped and staggered like a newborn deer with her footing. Her torn jeans slipped off and she reached for her crotch only to make a horrifying crotch. "WHERE THE FUCK IS MY COOCH!?"

"Back here!" Heather called out, making sure the cameras got a good view at what was between Leshawna's hindlegs. It earned her a **** glare from Leshawna but Heather wasn't intimidated. If anything, it just made her smile more.

"If the two of you are finished-" Blaineley started.

"Yeah, yeah, I know. Just give me the stupid challenge so I can sit back down."
