Teacher seduces the punished student

It happened in a private academy that laggard and troubled young boys used to go to. but what they did not know is that a degenerate had crept in among the teachers. his modus operandi was always the same, when he saw a boy who attracted him he told him to stay at the end of class. it might seem like a kind of punishment, but he knew how to do it so that it didn't. once alone, the man always approached his student before the boy's astonished face. what happened next you can imagine. the funny thing is that not all the guys he has fucked were gay, many were straight ... but they succumbed to the obvious charms of this mature man.
