The hum of the engine and the rush of the wind through the open window create a symphony of sensation for our horny driver. He can't help but let his hand wander, tracing the outline of his cock through his jeans. He pulls over, not wanting to risk an accident, and leans back, unzipping his pants. His hand wraps around his hard shaft, matching the rhythm of the nearby traffic. He imagines the drivers passing by, unaware of his hidden pleasure, as he fucks his hand, his body tensing with each stroke. With a final groan, he comes, his hot seed spilling out, a solitary moment of ecstasy on the open road.
