My father-in-law is tired of nursing care. One day, he sees his father-in-law. The ugly erection of an old man who survived the Showa era was to appeal something unconsciously to the uterus of ‘Nanme’. From that day on, my father-in-law's strawberries will be unforgettable. He has misunderstood his sexual desire every day through self-consolation, but he can no longer stand it and asks for his father-in-law's body.
