Six months ago, Chigusa started living with her daughter and son-in-law. One day, Chigusa witnessed her daughter's couple having sex. Since her husband passed away, Chigusa had been celibate and became excited, leading her to masturbate. From that day on, Chigusa began peeping at her daughter's couple having sex and would masturbate in the kitchen or bathroom. One day, when her son-in-law was in the kitchen, Chigusa entered. Her wrapped towel fell off, leaving her naked. The son-in-law became excited and pounced on Chigusa. 'I heard you masturbating in the bathroom.'
