Mack, a soldier with a secret, finds solace in the privacy of his room. His lean, muscular body glistens with sweat as he strips down to his boxers, the tight fabric leaving little to the imagination. With a hungry look in his eyes, he pushes his hand down his pants, grasping his throbbing cock. He strokes slowly, his breath hitching as he builds a rhythm. The room fills with the sound of his pleasure, his moans echoing off the bare walls.
