Rina's father-in-law, who was a woman-loving wife, put his hand out of the house and got into a man's trouble. "Rina" who gives his own body to help his father-in-law. His father-in-law cries at the figure. A man's request cannot be fulfilled at one time, and he repeatedly asks for his service. And her mind changes, and gradually she becomes obsessed with sex. What's going on with her husband when he is on a business trip? Review number 247859.
