I was 15 when four boys caught me and my girl friend naked in the school's shower. Thought they were other girls walking in till I saw them sitting on the bench looking at us. I remember they most have quietly sneaked in to remove anything we could use to cover ourselves. The shower didn't even had curtains and basically we were stuck standing there starck naked with our arms crossed in front of us facing the wall. In the end we had to turn around, swallow our embarrassment exposing our private parts before becoming the laughing stock of the whole school. I remember them comparing witch one of us had bigger breasts and threatening to lieve us with no clothes if we did spread our legs. Watching them squatting down looking up at us was the most bood rushing shame I had ever felt. The whole incident went unreported and we both kept that way. No teacher our school staff ever found out. But boys talk and we both knew what other boys in school were giggling about.
