In a cramped, dimly lit room, Nao Kojima's petite frame bends and stretches over her patient, her fingers kneading his muscles with professional precision. Yet, as she leans in, her breath hitches, and her nipples harden against his back. Nao's eyes flicker to his crotch, noticing the growing tent in the sheets. A mix of innocence and curiosity plays on her face as she reaches out, her tiny hand wrapping around his thick shaft. She freezes for a moment, then, with a shy glance at the door, she begins to stroke him, her slender fingers moving tentatively at first, then with growing confidence. Nao's cute moans fill the room as she discovers the power of her touch, her patient's groans of pleasure spurring her on.
