Six months ago, Chigusa's daughter got married and she began living with her husband. One day, Chigusa witnessed her daughter and husband having sex. Having not had sex for a long time since her husband died, Chigusa became excited and masturbated. From that day on, Chigusa started spying on her daughter and husband having sex, and masturbating in the kitchen and bathroom. One day, Chigusa came in while her son-in-law was in the kitchen. The towel she was wrapped around her fell off, leaving her completely naked. Her son-in-law became excited and jumped on top of Chigusa. "I could hear you masturbating in the bathroom."
