Shioko, 32, an elegant and refined lady married to a husband working at a top-tier trading company—the perfect couple on the surface. But behind this facade of happiness lies suffocating repression and stress, gradually warping her sexuality. On days when her husband is away, she indulges freely with men she meets through dating sites. It's during these encounters that her masochistic side blossoms. Her nipples are extremely sensitive—just being touched makes her wet, and when tightly pinched or sharply twisted, she clenches up in intense orgasms, squirting uncontrollably. Her slender body contrasts with her lewdly enlarged, erotic nipples. Witnessing this upper-class housewife embodying perverted, obsessive creampie masochism is a must-see masterpiece.
