When I was 12, many years ago.we all jerked each other off at school - in the toilets, in the classroom, changing rooms, wherever. We couldn't stop.
It was a boys' school, of course, so the frustration had to find a way out. I had a friend and we would slink off to the outside toilets to wank each other off in a cubicle. He made me pull my trousers and pants down below my knees, and then he would hold me while he pulled himself off. I usually came before he did.
