Pick up a close couple. To the boyfriend, "Let me see your girlfriend having sex with someone else. I won't do it for free. I'll give you 1 million yen as compensation." She thinks she's receiving a high-end spa treatment, but as the procedure escalates, she can't hide her confusion! Instead of stopping him, her boyfriend even starts cheering. In front of his eyes, rubbing? Internal ejaculation? A slippery soap experience.
