Mark's fingers dance expertly over his throbbing member, his grip firm and steady. He's in no rush, taking his time to appreciate every inch of his shaft, from the sensitive head to the base where it meets his body. His other hand cups his balls, gently rolling them, enhancing the intense sensations coursing through him. His breath hitches as he feels his orgasm building, his strokes becoming more urgent. He leans back, his body tensing as he comes, his cock pulsing in his hand, his release coating his fingers and palm.
