Amy walked out to the streets. People around her seemed shocked, disturbed or confused, and it generally seemed like there were less people outside then usual. There didn't seem to be any active panic, but there was certainly a general sense of unease.
She walked up to Grace's apartment. As she moved she could feel that she had a penis in her pants. It bounced around and moved with her body in a way that felt so unnatural to her. She could just always feel it sticking out of her. She also began to notice the strange feeling of not having a vagina anymore.
When she got to Graces she felt a bit strange knocking on the door. She decided it would be for the best if she just walked in, she didn't really have a frame of reference for the situation anyway.
The momment she stepped in she saw Grace, on her body was nothing but a T-shirt. Her pants were lowered to her knees.
Grace's body look as it normally did. She was petite and slender, though a bit taller then amy, her skin pale and her hair dark, with delicate features on her face. However, right in the middle of her crotch was a throbbing penis, about six inches in size, but massive looking compared to her body. It seemed Grace was inspecting her new appendage, though luckily it was limp. There was something so shocking about seeing her friend with a penis, and something so sad knowing this was what humanity was now.
