In the privacy of his room, our anonymous masturbator strips naked, his massive cock already rock-hard. He wraps his hand around it, feeling the pulse of his own desire. He starts slow, building a rhythm, his grip tight, his breathing ragged. His free hand squeezes his balls, adding to the intense sensation. He switches to a two-handed grip, his body arching as he fucks his fist, his cock slapping against his stomach. With a guttural groan, he comes hard, cum shooting out, painting his abs and chest with his own release.
