Hi, when I was in a class at junior school age five to seven, we had a female teacher who used to spank only the boys fir punishment! We wore shorts trousers so she would bend us over her knee, pull up our short trousers and underwear and spank our bare butt in front of the whole class!
Fine, we were young, didn't think too much of it. One day one of the older boys came in, he was around twelve, last year before senior, he said something she didn't like so she grabbed hold of him, problem was he had long trousers on as he was older, she then pulled them down, his underpants came down with them and she spanked his totally bare bottom in front of a class full of kids.
Before she finished he was crying his eyes out, probably more with humiliation than pain. She pulled up his pants, obviously she had a good look at his penis, and he ran out. His form teacher came in five minutes later and there was a huge argument between them!
Anyway, about six years later that boy committed suicide by drinking something poisonous. I often wonder whether the spanking he received at school had anything to do with him committing suicide. Just to make things worse for him, his young sister was in our class and witnessed what happened to her older brother!
