A few years after getting married, my husband's mother passed away and my wife Mizuki decided to live in the countryside. However, the obscene gazes and actions directed at my brother-in-law, Mizuki, who spends time with me, have escalated day by day. It was Mizuki who consulted her husband about it, but her husband opened his wife's body and taught him how to please his brother, saying that he should thoroughly do it to his brother who stopped halfway. After that, my younger brother played with Mizuki's body, but my father who witnessed the scene also received Mizuki's body.
