For financial reasons, Akari and her husband have begun living with her brother-in-law Taro. However, Taro's unrestrained nature irritates the honest Akari, unknowingly. Then, she has the opportunity to go drinking with him. Akari confesses to Taro that she is not having sex in the drunken state, and Taro is so aroused by her cuteness that he forcefully takes her. Akari cannot resist the forcefulness that is completely different from her husband's gentle caresses, and her body climaxes, craving pleasure every time Taro touches her.
