Professor Ariella Ferrera is having a bad week. She's trying to grade Johnny's test, but her pen ran out of ink, her drawer is locked and she's dropped files everywhere. On top of that, her home is flooded due to a broken water main. Johnny, being the good student he is, wants to help his teacher, so he gives her some good advice: have an orgasm. And as a matter of fact, just to help her, Johnny sticks his hard cock in her tight pussy while grabbing her big tits from behind!
