Excesive punishment

A girl found herself alone in class during recess and decided... well, to masturbate a little. But class started earlier than expected, and her arousal wouldn't subside since she couldn't finish, so she decided to take a risk and finish in class without anyone noticing... Then she asked to go to the bathroom and thought she could relax, but... But what she didn't know was that her teacher was a seasoned pervert with many years of experience and knew perfectly well when a student masturbated in class... I don't know what the punishment is for catching a student masturbating in class and trying to hide it by going to the bathroom... But certainly, dragging her to a secluded classroom, having vaginal sex with her until you ejaculate, and then anal sex until you ejaculate again while pulling her hair, is neither normal nor legal... But if, on top of that, you then force her to return to class, almost naked, with your semen leaking out of her so that all her classmates know what she's done and how you've punished her... And making them complete the punishment, that's completely unacceptable.
