Yui was frustrated because of her busy and absent husband. One day, her son-in-law Akira sees her masturbating in the bathroom. Agitated Akira touches Yui's sleeping body, but she tries to escape when Yui wakes up. Yui, who could not stand the pain of her body, stopped Akira as it was and piled up her body. After that, Akira asked for her Yui's body every time.
