Kai has a rather strange obsession with his stepmother, Artemisia. He stares at her breasts, follows Artemisia around the house, and tries to caress them from time to time. Fed up with her stepson’s attitude, Artemisia hires Sarah, a super nanny who specializes in such fixations. Sarah has a strict approach to teaching perverted young men like Kai. First, she takes out her huge breasts and asks Artemisia to do the same. Then, they test Kai by forcing him not to touch them while he looks at them. Next, he receives his first real punishment: watching hours of porn videos. The plan doesn’t work, as Kai ends up masturbating obsessively to these videos. That’s when Sarah realizes that the problem is much bigger than she thought and that she should try a different method. He asks Artemisia to take her breasts out again, they try aversion therapy, rubbing his cock between his tits and sucking his penis, while spraying him with water to try to generate his self-control. Finally, Artemisia and Sarah realize that they have been doing it all wrong. It is not through rejection that Kai will learn to cope with his obsession. He is still a virgin and just needs to have sex to make those intrusive thoughts go away. Artemisia and Sarah join forces to give Kai his first sex to finally cure his obsession.
