A well-mannered, refined woman waits at the edge of a sidewalk. Her name is Yuu, 21 years old. Though she works as a night butterfly in adult social circles and meets many people, she hasn't had a boyfriend in two years. The reason she decided to participate? Simple—she wanted sex. Contrary to her mature appearance, she's wild at heart and absolutely loves sex. When she can't hold back, she indulges in masturbation using the corner of a desk or the floor—a habit dating back to kindergarten. Looks can be deceiving, indeed. Slightly nervous from it being her first time in a while, she quickly undresses. Soft, supple, flawless skin is revealed, and her beautiful C-cup breasts sway gently. Her nipples are already hard, and as they're touched, she can't help but let out moans mixed with breathy sighs. Her pubic hair is neatly trimmed, and as fingers slide into her pussy, slick inner walls wrap around them just right, flooding with arousal. When the gently sucked, rock-hard cock eases into her vagina, she closes her eyes and wears a blissful expression. The vaginal muscles now grip tighter than before, pulsing with wet heat along the shaft, delivering intense pleasure. Yuu loses herself completely, grinding her hips wildly, greedily chasing climax—an unforgettable sight.
