Max is very protective of her little sis. She found out that her step-sister's boyfriend cheated on her. She confronts the boyfriend and plans to punish him for what he's done. And when Misty, Max's friend walks in, it turns out that the cheating boyfriend is in for a real punishment. The girls make him take off his pants and underwear. He claims he'll do anything to get back with his girlfriend and Max decided to kick him in the nuts as punishment. Misty wants to get in on the action too. Kicking guys in the balls looks like fun to her. Max ties him up to make sure he can't protect the precious cargo between his legs and the girls take turns ballbusting him. Surely this will be a step-son he won't forget for a long time.
