In the dimly lit room, a shirtless man, his eyes closed, leans back against the wall. His hand, a tight fist, rhythmically pumps his engorged cock. Veins bulge as he grips himself firmly, his wrist twisting with each stroke. He's lost in the sensation, his breath hitching as he nears the edge. His balls tighten, and with a final, aggressive tug, he spills his load, grunting softly as his hot cum coats his hand and stomach.
