He fucks a schoolgirl after her mother has eaten his dick

Every once in a while, this man fucks a schoolgirl because young girls try to rob his shop, and he catches them. What he always does is call the girl's mother and explain the situation. He tells them that he'll forget what happened if they both get her to come out and enjoy a good fuck. The mother wants to do everything and starts by giving the man a blowjob, but when he has it hard, what the bastard does is put the student on all fours and fuck her while the mother watches.
