Kinda long story, but here goes nothing.
Basically, the showers in the male changing room at my old school was situated opposite and below the female side of the boarding house. So if you went down for a show early in the morning, you could climb on top of one of the big lockers and see out of the small window up into the girls' rooms, and if you were lucky, you could perv on them while they got dressed.
Now one day, a mate of mine and myself went down nice and early to do precicesly that. Unfortunately, the Headmaster's office is en route from our bedroom to the showers. So as we walked passed, he noticed us and wondered what we were up to. Skip forward 15 minutes and you have 2 12 year old boys crammed into a tight space watching the girls change. This is when the Head walks in and immediately guesses what we are doing. He tells us to come straight to his office and explain ourselves. However, the worst was yet to come.
At our school, we have an assembly every morning where announcements are made etc. Now the Head, who by the way was a massive cunt, made me and my friend announce to the whole school that from now on all girls should make sure that their curtains are closed while changing to ensure that no one watches them. So if having the entire school know what we did wasn't bad enough, he made us explain what we had done to our parents.
That was the single most embarrassing day of my life
