A married woman's heart and body swaying in hot springs and love. Former maiko and full-time housewife, she is married to a 28-years-older company executive. Feeling unfulfilled and treated immaturely in both daily life and sex, she embarks on a journey outside her routine. Under the setting sun, she melts into a man's arms, her lower body trembling restlessly as she receives affection. Her face flushes as her genitals are stimulated, moaning audibly. When the penis penetrates, she screams in ecstasy, her entire body turning pink as she writhes in pleasure. After dinner, the uninhibited wife exposes herself, expressing pleasure as her nipples are bitten hard and her buttocks slapped. She takes the man's cock deep into her throat, orgasming intensely during sex, then basking in post-coital satisfaction. Three weeks later, lured again by the man, she returns to a hotel. Overwhelmed by foreplay and intercourse, she writhes in ecstasy, moaning and crying out as she's taken from behind, climaxing repeatedly.
