Mikako appeared to be the perfect wife and mother in front of her family, but in secret, she had been carrying on an affair. One day, her son caught her in the act. Overwhelmed by pent-up desires she could no longer suppress, she propositioned her son for anal sex. Eagerly intrigued by their mother's advances, the sons took turns ravaging her from top to bottom, penetrating both her anal and vaginal holes simultaneously. The pleasure she experienced was unlike anything she had ever felt through masturbation.
