In the privacy of his bedroom, a young man, driven by primal urges, begins his solo indulgence. He tentatively strokes his growing erection, feeling the familiar heat building. His breath hitches as he picks up the pace, his hand slick with pre-cum. The room fills with the sound of his wet, slapping strokes, his moans echoing off the walls. His body tenses, and with a final, shuddering stroke, he releases, ropes of cum painting his chest and hand.
