In the quiet of his room, a chubby man in a blue Adidas nylon tracksuit can't resist the temptation. He strokes his small, hard cock through the soft, clingy fabric, feeling every ridge and vein. The nylon squeaks softly as he grinds against his hand, the friction sending waves of pleasure through him. His breath hitches as he feels the cum building in his balls, and with a final thrust, he explodes, leaving a warm, sticky mess on the tracksuit.
