Mary downed the vial quickly. The liquid tasted bitter and chalky. "Ugh, gross. That was worse than the last one." Mary said. After about 10 minutes, nothing had happened.
"Just as I thought. Just a waste of money. I should hav-"
Suddenly, Mary felt odd. She felt a strange tingling in her abdomen. The feeling grew stronger and spread to her crotch. It was as if her insides were being rearranged.
"Oh god. What is this? Is it- oh fuck..." Mary moaned. The feeling was now almost exclusively in her crotch. She could feel her vagina start to close and her clit start to grow.
She felt a pushing just below her clit as a pair of testicles popped out of her. Mary's clit continued to grow until it was about 6 inches. As her new equipment pushed out of her panties, Mary touched it.
"Holy fuck. That is a dick. I have a dick. Jesus." Mary said.
She stood up and went to the mirror in her room. Staring back at her was her own shocked reflection, along with her new appendage poking out.
"Why is it hard already? I guess these thing really do have a mind of their own."
Mary examined her dick. It was pretty average sized. Just a tad smaller than her ex boyfriend's. She looked at it through all angles and cradled her balls.
A pressure began to build up. She had to pee. She ran to the bathroom. "I have always wanted to try this." She began to relieve herself and didn't take into account that her erection would make it difficult to aim.
"Shit. What a mess." Mary cleaned up her piss and washed her hands. She looked down...her dick was still hard.
"Fuck. Don't these ever go down? Maybe I need to...umm."
