In a dimly lit room, Jstn89's cock twitches, ready to explode. His fist pumps furiously, the sound of skin slapping skin filling the air. His abs clench, and then it happens - a hot, sticky stream of cum blasts from his cock, painting his chest and stomach. He continues to stroke, each pulse sending another rope of jizz flying, until he's left coated in a glistening, mess of his own making.
