Masaru's friend says to him, "Your mother is really beautiful, isn't she? One night, Masaru's mother, Miho, invites her husband to have sex with her, but when he refuses, she masturbates next to him out of uncontrollable sexual desire. Masaru wakes up by accident and sees Miho masturbating, and his feelings for his mother as a woman grow. Masaru takes the opportunity of his father's absence on a business trip to tell Miho how he feels about her over and over again. Masaru's desires and feelings overflow, and he and Miho have physical intercourse in the house alone with his father, who will be back soon.
