Chiharu recently started living with her husband's father. However, because of her father-in-law's history with women, he was worried about her living with him. Even when she's doing housework, I can feel his eyes on her chest and buttocks...my suspicions grow even more. One day, when Chiharu sees off her husband, her father-in-law stands in front of her and attacks her. Pleasure that her husband couldn't give her. Drowning in SEX with her stepfather...
