Risa is approached by a man claiming to be the director of a popular TV show, and she readily agrees to be filmed, inviting him into her home where she lives alone. Off guard, the man takes advantage of her weakness. The man's modest demands, such as pushing her to masturbate, gradually escalate. He does not care even when she is on the phone with Akinobu, which is her daily routine. She continues to talk on the phone with Akinobu, stifling the pleasure in her voice, but she is gradually swallowed up by the waves of pleasure.
