A mysterious figure, parked on the shoulder of a dimly lit highway, can't resist the temptation any longer. He rolls down the window, letting the cool night air in, and unbuckles his pants, freeing his aching cock. He begins to jerk off, his hand moving rapidly, his breath coming in ragged gasps. The thrill of potentially being caught only adds to his excitement, and he feels his climax approaching. With a final, desperate thrust, he comes, his cum shooting out and landing on the roadside gravel, a secret, sordid moment in the darkness.
