The neighbor Ando and the owner of the Sawaguchi family are book-lending friends, and Mihoko has become quite acquainted with Ando, who often comes over to the house, and they even have dinner together occasionally. However, Mihoko doesn't realize that Ando is looking at her with wicked eyes... One day, when Ando comes to return a book, he finds the front door unlocked, so he goes inside and finds Mihoko asleep on the sofa, tired from waiting for her husband to come home. Ando caresses Mihoko's body, exposing her private parts, revealing a hairy area that is hard to imagine given her pure features.
