After the husband was laid off and decided to move back to his in-laws' house to save money, the Shigeyama couple returned to the home where his father-in-law lived alone. The wife, Mizuhō, found it difficult to relax while spending time with her father-in-law and tried to relieve her tension through masturbation, but was caught by her father-in-law who had returned... Her father-in-law, who had always been quite the womanizer, seized this opportunity to prey on his daughter-in-law's fresh body. Unable to consult her husband, Mizuhō was raped as ordered. However, her father-in-law subjected her to further humiliation, exposing and tormenting her.
