Matsuri has married a kind, albeit slightly unreliable, husband and has quit her job to become a housewife. However, Matsuri has one complaint - living with her vulgar father-in-law. She hates being alone with her father-in-law during the day when her husband is not around, so she goes to work, but she falls asleep tired from being busy and alone at home with only her father-in-law. When her father-in-law finds her defenseless, he takes advantage of the fact that his son is not around to rape her young, voluptuous body. From that day on, whenever he finds an opportunity, the father-in-law rapes his beautiful wife, repeatedly cumming inside Matsuri despite her reluctance.
