Reiko (Reiko Sawamura) was so estrus that she lost sight of herself and pushed her down because of the pant voice of her neighbor that she heard in her son's room. Reiko who is excited by a nasty voice masturbates on the spot. But I still want a cock ... When I thought so, what caught my eye was the crotch of my child who had an erection when he heard the voice of his neighbor like Reiko. The moment I saw the scene, Reiko turned into a sexual beast.
