Rieko had secretly harbored a desire to have unprotected sex during her married life. At her husband's request, she ends up drinking alone with her close neighbor—the husband of a family they're close with. As they both become pleasantly drunk, they realize their mutual feelings and confess their shared desire: "I want to do it bareback." Though her love for her husband wavers, her uncontrollable lust begins to overwhelm her. Before she knows it, skipping foreplay entirely, Rieko urgently demands bareback penetration. Overwhelmed by the pleasure of a bare penis, the guilt of cheating, her lingering love for her husband, and her arousal toward her partner's attractive cock, she eventually reaches a creampie orgasm. A woman's desires run deep—deeper than anyone knows.
