The fifth reprint of the legendary masturbation work "Virtual Ona" by the genius director Takuto Watanabe. In a corner of an empty classroom, Nana, a female teacher, masturbates by pressing her crotch against a desk. Her breasts are visible through her thin blouse, and her glasses give her an intellectual air, making her look very erotic. She eventually spreads her legs and thrusts her fingers in and out of her wet pussy, facing the camera.
