Amy didn't know what to do next. She tried to pretend nothing was wrong, and go about her daily routine. But with every step, and slap of her balls, she was reminded that something was VERY wrong. Though the cock has retreated inside its sheath, Amy could still smell the distinctly dirty animal scent coming from it.
"What the hell am I going to do? People don't just grow horse cocks. How could this have happened? That lab we went to... no I didn't touch anything but that beaker. Oh god, maybe I shouldn't have breathed any of it in. But how the hell did that stuff make me grow this thing?! God I'm going to end up in a freakshow." Amy woefully thought. She sat at her kitchen table and held her head between her hands. She didn't know what else to do other than let her mind drift to the worst case scenarios.
While taking her shower she further inspected her body. She's already had suspicions, but after lifting her massive ball bag out of the way, Amy confirmed that her vagina was gone. And to her horror, her asshole had puffed up until it was just like a horse's. That seemed to be the extent of her changes. At the moment. Because the chemicals were still swirling around her body, slowly progressing the changes. Amy was so frantic about her new genitals she didn't even notice the long line of fine hairs growing down the back of her neck.
A sudden knock at the door startled Amy, and she whipped her head around. She took deep breaths, calming herself until the pounding in her chest stopped. Why had the knock at the door spooked her so much? Wait, spooked?
"I am not a horse. I'm a person dammit." she thought, getting up to see who was at the door. Wearing only a bathrobe, as it was the only thing that fit her, Amy clutched the belt like it was a life preserver.
