The third installment in the series where a mother who loves her son too much teaches him about sex with her voluptuous body! To train the lower half of her son, who seems disinterested in sex despite being of age, she wears a fundoshi and shows her body to him. Natuko, overwhelmed by her son's erection at the sight of her large breasts and fundoshi-covered crotch, performs fellatio and 69, extracting his semen. Furthermore, to teach him about a woman's body, she lets him touch her ample flesh while explaining carefully, guiding his penis into her vagina in a hands-on sex lesson! This series is packed with extreme fundoshi sex education!
