Sumire and Kenji, a newly dating couple, are innocent like they're just holding hands for the first time after school. One day, Sumire comes to Kenji's house to meet his father, Kenzou. While teasing the innocent couple, Kenzou becomes smitten with Sumire, who is polite and adorable. When Kenji asks Sumire to cook for his birthday, she makes curry on the day. Kenzou, who has been watching her with lustful eyes, puts sleeping pills in his son's curry and aphrodisiacs in Sumire's curry! Pretending to be worried about Sumire's excited state, Kenzou touches her all over, acting like a beast while his son sleeps soundly beside her.
