In the dim glow of the bus's interior lights, a solo passenger finds his secret delight. His hand wrapped tightly around his stiff cock, he pumps furiously, the motion of the bus pushing him closer to the edge. His breath comes in ragged gasps, and he can't help but imagine the thrill of being caught in the act. As he reaches his peak, he lets out a low groan, his hot cum painting the bus's upholstery with a glistening, sticky masterpiece.
