Hidden from the world, he stands, a silhouette against the dim light. His hand, calloused and strong, wraps around his stiff shaft, pumping with practiced ease. His breath hitches as he imagines unseen hands, mouths, and bodies. His free hand roams, pinching nipples, squeezing balls, and probing his own tight hole. The room fills with the scent of sex, the sound of flesh slapping against flesh, and the growls of a man lost in his own world of pleasure.
