A rape sex movie of Karen Yuzuriha, Father passed away in a traffic accident, mother Yuzuhira decided to take the next step with the hope of having someone to be the pillar of the family, always loving and taking care of mother and child. However, life is not so rosy. Yuzuhira’s stepfather is a patriarchal person, always looks down on women and is often angry, ordering her mother not only to do housework in the family but also to work outside to earn money to support him. Yuzuhira’s mother’s plans were ultimately not outlined as desired, even counterproductive. However, that is not all, he is also extremely perverted, often spying on Yuzuhira when she goes to take a bath. One time when she was masturbating, he suddenly rushed in and forced his wife’s stepchild to have sex with him and then threatened her not to reveal this. At first, Yuzuhira was very scared and disgusted, but after being raped for the second time while watching TV, her mood completely changed, replaced by a feeling of pleasure and novelty when having sex for the first time. Just like that, she was increasingly drawn into the illegal incestuous affair between herself and her stepfather.
