In the quiet of his room, he indulges in his secret vice. His hand, a faithful companion, knows the map of his body well, tracing the contours of his need. His cock throbs in response, eager for the familiar touch. He imagines unseen hands, untouched bodies, feeding his fantasy. His strokes become more insistent, his grip more firm, until he's a symphony of sensation. His breath comes in ragged gasps, his body tensing as he hurtles towards his climax. With a final, guttural moan, he finds his release, his cum painting his abdomen in a lewd canvas of his solitary sin.
