Chisato was troubled... Just when she felt relieved that her painful menopausal symptoms had subsided, she felt a strong sexual desire like never before. After some research, she discovered that "after menopause, women's sexual desires can increase due to an increase in male hormones." She spent her days dealing with her strong sexual desire on her own. One day, Chisato was left alone with her daughter's husband. Coincidentally, her husband had not had sex with her while her daughter was pregnant. When Chisato found out about this, she approached her daughter's husband... "You don't have to be shy. I know how painful it is to hold back your sexual desire." Up until this age, Chisato had maintained her rationality and lived an honest life. But her rationality broke down and she began to drown in instinct and pleasure.
