Rin isn't on good terms with her husband, but she's dissatisfied with the fact that she hasn't been with her at night lately. One day, her sister-in-law Mio came to visit her house. The three of them sit around the dining table and drink, but her husband passes out and falls asleep first. Partly because of the drunkenness, the conversation between the women was lively, and the conversation turned to the topic of nightlife. However, Mio, who heard her dissatisfaction with Rin, pushed her down and exchanged her rich kiss. She was confused, but she was numb by her unknown pleasure and accepted lesbian play.
