Did this as a teen in the bathroom and my penis head came out the other end. Because of the tight fit my cock began to become swollen and I couldn't get it off. At the same time one of my younger siblings began to knock on the door saying he had to go to take a piss (we had only one bathroom). Figured I better do a quick jack off and shot a load so it would go down. As I was jacking I told my brother to shut up and that I would be out when I had finished shitting. When I came out of the bathroom I got the usual from my little brother, "I know what you were doing and I'm going to tell." He never did because I knew he was doing the same thing. I also did not put my cock in a toilet tissue roll again. |
