Three years ago, a young wife named Anzu married her husband. In terms of family life, she was living without any inconvenience. However, there were two things that bothered her: one was that her husband was weak at night; the other dissatisfaction was with her father-in-law, Shozo, who lived with them. Shozo was a lecherous old man who blatantly stared at Anzu's daily life. But one day, after seeing Anzu masturbating and getting overly excited, Shozo collapsed. 'Since then... I started using my father-in-law for my amusement.'
