New wife Runa Tsuki holds the unique position of having three husbands. She takes great pleasure in fulfilling her husbands' desires, whether it's giving blowjobs during breakfast, having sex before they leave for work, mutual masturbation while doing laundry, being tied to a clothesline for humiliating fondling and intercourse, or performing devoted blowjobs while cleaning the floor. Runa values her husbands' satisfaction above all else. However, among the three husbands, one man stands out as unusual—he never touches her. His reason? A personal belief that he never makes a move on a woman he truly likes. As a result, while Runa deepens her relationships with the other two husbands, a special emotional bond gradually develops between her and this one untouched husband. In the finale, Runa Tsuki engages in passionate, tearful sex, pouring her true love and longing into their encounter. This intense, deeply erotic climax is an absolute must-see.
