school memory

I have a teacher, who is also a conductor, who always when we do something stupid at school, we have to choose between low points for behavior or a good spanking! The last time I got it from him was in June, when I - I fought with a colleague, then I stayed after classes, I went to the office, I took off my pants and he started to beat me with his belt and his palm on my asshole, I started to cry at the 20th belt out of 100, after which I took off my stockings, and applied 20 blows to my soles with a thick stick! Fffff... What a sting!
I left there crying in pain!
