Alone in his dimly lit room, a man's hand traces the throbbing outline of his hard cock through his jeans. He unzips, releasing the stiff, veiny shaft. He grips it tightly, his fist pumping up and down as his breath quickens. His other hand cups his sac, feeling the weight, the heat. He leans back, eyes closed, lost in the sensation of his own flesh, the pleasure building with each stroke.
