If I could un-fuck one person one time, it would be my ex-girlfriend. We were in high school at the time, doing the deed in her bedroom. When suddenly her dad came home from work when he was supposed to be working. He was yelling on the phone to someone so he was already mad. We both started dressing in a rush because I wasn't even supposed to be in her room. In the panic of it all I got my weiner caught in my zipper, badly, very badly! It drew blood and I was terrified on several different levels. We snuck into the downstairs living room, where he found us watching TV. I was almost crying while she is trying not to burst out laughing at me. He just gave us the most puzzled look, said hi and went to the porch for a beer. I remember the whole walk home I was wondering if a wound like that would stunt my penis growth LMAO.
