My younger sister who is 16 and in ss2 said something in the mist of her friends but I grabed it and feel a need to react. She was complaining to her friends that their goverment teacher is always saying something strange to them in class every time he dictates and they don't get what he said.so they tell him to come again.then the guy would reply.where do you want it.should I cum on ur face.or the guy will say I don't cum that easily. They don't understand but they will eventually understand.I feel angered and something should be done cos it sounds so inappropriate. And gross to say such in front of kids
