I was hired to teach a class at my son's school, when I got to the classroom I noticed that his bully was also there, I tried to teach the normal class but he approached from behind without respecting my son's presence and started spanking me mercilessly, I asked I have to stop because my son is watching us and listening to him for a little while and after spanking me hard he pulls down my thong and pushes his fingers into me with so hard that it makes me clap and move my desk, distressed for my son, I try not to moan even though Moans come out, he doesn't stop, after masturbating I can't stop him, he compel me to take off my heels, put my feet on the desk to masturbate more comfortably, I tell my son not to look at us and to pay attention to the class, his bully He doesn't stop until he fucks me and comes, I must leave the room quickly before they discover us
