Des：Miki, a housewife, has remarried her new husband and started a new life with her son Junpei. Junpei also grew fond of her husband, to the point where he felt like they were father and son, related by blood. However, perhaps because of their close relationship, her husband ends up instilling Junpei with her radical sexual knowledge. Worried about Junpeis future, Miki attempts to give her husband proper sex education in his own way without telling her husband. How to kiss, how the female genitals work, and even penetration... She uses her voluptuous body and big tits lavishly to teach her son the love of sex.
