In the privacy of his room, a man, driven by primal urges, finds solace in self-pleasure. He unzips, revealing a hard, throbbing cock, already slick with pre-cum. With a firm grip, he begins to stroke, feeling the vein pulse with each tug. His breath hitches, and his hips thrust forward, hungry for more friction. The room fills with the sound of skin slapping against skin, and the scent of musk. He's close, his body tense, and then with a final, hard pull, he spills over, painting his abs with hot, sticky cum.
