Masturbating to the small man on the bus who remained thirsty

On a hot, steamy bus ride, a guy gets turned on by the sight of his buddy\'s throbbing member. Unable to resist, he starts jerking off, his strokes growing more frantic as the bus bounces along, making him feel even more aroused. The sensation is overwhelming, and he can\'t help but shoot, covering his buddy\'s stomach in a satisfying climax.
