This is Minami's first time visiting her husband's home, where he was born and raised. But it seems like her in-laws are arguing, with both of them not talking or caring about each other. However, Satoshi explains that it's probably because his father often drinks, so Minami overlooks it. The next morning, her father-in-law claims to be sick, so Minami stays to take care of him while Satoshi goes to meet his childhood friends. Her father-in-law treats her to a jelly dessert, and while she's eating, she feels extremely drowsy. When she wakes up, she realizes that she's being violated by her father-in-law and reaching climax without even realizing it. Because he recorded a video of their sexual encounter, Minami has no choice but to comply with his demands. Her mother-in-law discovers everything, but she can't do anything because she herself is having an affair!!!
