While quietly masturbating in a private booth at an internet cafe, a gyaru suddenly walks in and says, "I don't have a place to stay and I'm working as a masturbation support girl—wanna give it a try?" After agreeing, she says, "Then jerk off exactly as I tell you," and begins guiding the session. The thrill of masturbating while sneaking glances around intensifies the sensation, making your body shiver with pleasure. As she gets turned on, she says, "This is a special service," climbs on top, and grinds her big tits and pussy against your crotch. She climaxes from the intense, sex-like pleasure, then casually says, "Time's up, I'm heading out," and leaves.
