Diego, alone and horny, indulges in a marathon masturbation session. His thick, veiny cock throbs in his hand as he strokes with expert precision. Pre-cum beads at the tip, mixing with the lube already coating his shaft. His heavy balls tighten, ready to unleash a torrent of cum. Diego's grunts fill the room, echoing his intense pleasure. His abs clench as he nears the edge, then with a final, powerful stroke, he sends a thick, ropey load shooting onto his stomach.
