Its about a daughter introducing her new boyfriend(a dark haired buff guy) to her mother. I can't remember if the mother already knew him but I think so. Anyway, she begins an affair with the guy while he continues to see her daughter. He has control over the mother sexually. He takes her to this club with live sex acts being performed. Also one night at dinner, the mother goes outside to put the trash out and he follows. He does her right up against the window where her daughter and husband can turn around to see. Anyone remember this one?
