30-year-old Naoko. Her husband is around the same age, and their married life is going smoothly. However, Naoko harbors an intense desire to have sex with a younger man. Her target: a young dry-cleaning delivery man. He's not only youthful but also has a fantastic physique. Ever since she caught sight of him at work, her heart has been racing. The way he exposes himself during deliveries further fuels her lust. She can't resist the urge to invite him into her room and have sex. Eventually, Naoko lures the delivery man and invites him to her home. "You must be hot, right?" she says, stimulating his crotch with excessive body contact. Instantly, his cock stiffens. "You don't have to hold back," she whispers, letting him touch her proud, voluptuous body before giving him a blowjob. The day finally arrives. While checking for stains on his underwear, they proceed directly to sex. The long-restrained Naoko climaxes repeatedly, discovering new pleasures at the peak of her desire.
