In the dimly lit room, a man in tight nylon shorts teases his hard-on through the fabric. The outline of his engorged cock is visible, straining against the shorts. He strokes himself slowly, feeling the soft nylon against his skin. The room fills with the sound of his heavy breathing and the rustle of nylon. His hand moves faster, and the shorts become damp with his pre-cum. With a final, desperate stroke, he comes, staining the shorts with his load.
