Horny Mash, alone in the bathroom, can't resist the urge to stroke his massive, throbbing cock. With pants down, he leans against the sink, his beefy hand gliding up and down his length. The bathroom fills with his grunts and the wet sounds of his jerking. His other hand reaches around to squeeze his heavy balls, intensifying his pleasure. He's close, his breath hitching, when suddenly, someone enters. He quickly covers up, catching his breath, his cock still rock hard and glistening.
