Shizuko wants a child, but her husband is indifferent to sex and ejaculates and falls asleep as soon as she gives him oral. Dissatisfied, Shizuko turns to masturbation. One night, her drunk father-in-law peeks at Shizuko while she's bathing. The next morning, after her husband leaves for work, Shizuko is raped by her father-in-law but begins to find pleasure in it and starts responding to him. A few days later, Shizuko and her father-in-law conspire to put their son to sleep and have intense sex together. This is the masterpiece of the healing-type mature woman, Shizuko Osaki.
