Private Lessons (2009)

A movie that pushes the boundaries and explores inter-generational sex and how an older man can take advantage of a horny teen. The adolescent is about to flunk out of school, primarily due to his focusing on improving his tennis game to move up to the pro ranks. He contracts with a tutor to help him get his secondary degree. As part of the deal he moves into the man's apartment and does light house keeping. The older man watches the teen masturbate and sets up various scenarios that lead to oral sex. The young man is having unsatisfactory sex with his girl friend and she eventually leaves him. After a few parties and some heavy drinking, the tutor sodomizes the teen making that sex act part of the learning process. As normal with French movies, there is sex, nudity and lots of dialog.
