One time when I was 13, I was showering after p.e(4th period). Since i have a small dick, i waited until the other people finished showering(it was mandatory). When they were all gone, I stripped and went into the showers. The water was very cold and my dick instantly shrunk to like 1 inch. Soon, afterwards I heard someone come in. It was one of my classmates who forgot his bag. When he saw my clothes and towel there, he knew that I was still in the showers. He took my bag(which contained my clothes and towel) and left. When I finished showering, i looked around.There was absolutelt nothing i could use to cover myself. I would have to go out eventually. But right outside the locker rooms is the main hallway, which would be loaded with students at this time. I decided to wait it out. Then I heard a frightening thing. Girls were coming in!!! It seemed their locker room was locked so the gym teacher let them in here, thinking everybody was gone already. As soon as they entered, I hid in the showers. Before I reached there, one of them saw me and told everybody. They all pinned me down and had a good laugh at my tiny dick. They all took turns touching and flicking it. I even ejaculated when one of them did it too hard. I was so embarrassed. They then threw me out and locked me out
