Family Fantasies 1435 - Family Obsession (2013)

Uptight Rachel is trying to protect her stepson Jeremy and her stepdaughter Misty from bad influences. Her late husband's Will stipulated that in order to gain their inheritance they must do well at school and not have sex before marriage. Meanwhile, Rachel's wild-living sister Dallas has come to stay, and is threatening to upset her best laid plans. When Rachel catches Misty and Jeremy masturbating, she goes to her husband's doctor and asks him for advice on how to handle the situation. He gives her an orb-like device that supposedly grants her the power to control other people's behavior. Little does she know that it actually possesses people and makes them sex-crazed. Before long she and her family are wantonly engaged in an epic taboo orgy. Because they have all misbehaved, the crafty doctor claims their inheritances by default.
