Do you know the secrets behind the seemingly innocent men's spa? We've secretly set up cameras inside a popular spa in Tokyo, collaborating with the manager to capture everything. Despite the "no touching" and "no ejaculation" rules, the masseuse starts getting increasingly erotic with her techniques. The intense stimulation makes the client's cock harden to the point his underwear is about to rip. Her hands caress his cock while giving him a massage, her fingertips teasing his balls. Unable to resist the masseuse's suggestive play, he climaxes multiple times, but she still wants more, relentlessly pursuing him with her expert skills and lewd massage.
