Wife's hospitalization Mother-in-law

Toshio's wife, Yumiko, has been hospitalized and he and his father, Haruo, are living a desolate life. One day, Yumiko's mother, Chizuru, comes to visit her house as she grows tired of the taste of instant food. Toshio gratefully accepts Chizuru's kindness as she cleans up his messy room and serves him hot home-cooked meals, but... From that day on, Chizuru visits Toshio's house every day. Chizuru's overflowing motherhood and overflowing body are too stimulating for Toshio, who lost his mother when he was young.
