Naughty tutoring! Community blowing in class

Has there ever been anything like this before? Our teacher is really tough and we all have detention. Nobody wants to do it and everyone knows it. We're loud and unfocussed and the teacher's in a rage. But he's really crass and spontaneous. I could hardly believe it but it really happened - he just pulls out his willy in the middle of the class and stuffs it into the mouth of the poor girl in the front row. Then the first pupil storms out of the room. That was probably too much for her. But as we always stick together, the three of us get it over with. The three of us suck the teacher's big cock and he's allowed to cum in our mouths too. Delicious, that warm sperm. But we deserve a good mark for that, don't we?
