Miyuki, a mother, is busy cooking before her husband comes home. Then her only son appears and stares at her with a fixed gaze. "Mom, let's do it again today," says her son, who asks for sex as if it were the most natural thing in the world. Miyuki is simply confused... In the past, she made several mistakes and offered her body to her son, and after that, he persistently asked her to have sex with him, and she ended up having sex with him. Miyuki glares at her son, who asks for sex in front of her sleeping husband instead of telling her husband, but she can't forget the thrusts that are even more intense than her husband's, and accepts her son's meat stick... She can't live without her son's dick anymore.
