Ex-gyaru Mitori Nagahama steps in to help her friend tame her virgin son's endless urges, only to be overwhelmed the moment she enters his room. Her voluptuous body is pinned down and relentlessly pounded by his massive cock, turning the tables as she goes from seductress to cock-drunk mess. Her moans grow louder and sluttier until she's left shaking, squirting, and rolling her eyes back in non-stop orgasms. What started as a simple favor ends with her completely broken and craving more of his raw, relentless pistoning.
