In the secret training den, Nezuko, the demon girl, finds herself in a compromising position. Her instructor, a lecherous sensei, uses her lustful nature to teach her new techniques. He feeds her kinky fantasies, making her finger her wet pussy while he strokes his massive cock. Nezuko's breath hitches as she feels her body respond, her nipples hardening. The sensei guides her through pleasuring herself, teaching her to take control of her desires. She moans softly, her body writhing as she brings herself to the brink.
