Erin pressed the male option without really understanding what was going on. In an instant the doors opened and Erin felt a tightness in her crotch and when she looked in her panties she saw a small penis and when she said "what the?" her voice came out a bit more masculine. She exited the machine and saw a full body mirror and saw a little boy in her clothes. Erin then thought to himself "What am I going to do?" He looked to the machine that was still open. It could help him turn back into a girl. Then again he should probably tell someone like his mother or his older brother. They may know what to do.
He walked around the room a bit thinking if he even wanted to be a boy he still needed to do something. Considering his clothes weren't changed Erin assumed everyone would remember him as a girl. Needing to go to the bathroom Erin saw a small bathroom down in the basement and he went inside and decided to use his new dick to piss standing up. As he was urinating Erin thought whether what he wanted to do and then.
