VENU-746 Nao Wakana plays with her dirty father-in-law's wife who has retired and has free time.

Nao, the middle-aged wife of a married couple living happily in a house, has a certain problem. That was because she no longer had any relationship with her husband. Then there was her stepfather, who lived with her and sexually harassed her. Nao turns a blind eye to the fact that this act was done out of loneliness after losing her wife, but her father-in-law's sexual harassment escalates as he takes advantage of Nao's behavior. One day, Nao's frustration with her girlfriend finally reaches its limit.
