Amano Koyuki is a married woman who tied the knot with a man ten years her junior. Expecting passionate nightly sex due to his youth, she was shocked to discover he preferred masturbation over intercourse. Watching him pleasure himself without ever satisfying her needs left Koyuki increasingly frustrated and starved for intimacy. When someone begins carefully massaging her sensitive spots, she reacts with surprising intensity, craving more. Finally, when she receives a bareback creampie, her satisfaction reaches its peak.
