Yukari, who lives with her daughter and her husband, is trying her best to make sure they can live happily together. However, she was saddened by the fact that her daughter's behavior toward her son-in-law was becoming more harsh day by day. Today too, when the son-in-law even slightly complimented Yukari's home cooking, the daughter became displeased and the atmosphere became awkward. Late at night, when Yukari heads to the kitchen, she finds her son-in-law sitting there with a depressed look on his face. When I asked him about it, he said he was more worried about things than cooking. The son-in-law is reluctant to say anything, but he opens his mouth and says that he has no sex with his daughter. Yukari made up her mind and licked her son-in-law's crotch, saying, ``I'm sorry, but just for today, just today, I'll make you feel refreshed.'' A few days later, Yukari asks her daughter if she doesn't want to have a child, but she successfully avoids it. Yukari brings laundry to her daughter and her husband's bedroom. Her son-in-law was lying down, but just as Yukari was about to leave, he hugged her from behind. He says no, it was just a special time, so he covers Yukari's mouth with a kiss and begins to play with Yukari's body. Although she hates it, her body begins to react and Yukari's underwear becomes slightly soiled. Her body began to open as her son-in-law teased her, and just as she was about to be penetrated, the daughter called out to her son-in-law. It was a relief, but I found myself aching because I wasn't completely satisfied.
