In the dim light of his room, a man's hands explore his body, his fingers tracing the lines of his muscles, his skin prickling with goosebumps. He's a black knight, a king in his own realm, and his desires are dark and intense. He takes his time, savoring the feeling of his own touch, his hands gliding over his body like a lover's caress. He pulls down his boxers, freeing his massive, throbbing cock, the head already glistening with pre-cum. He strokes it slowly, his grip firm, his rhythm steady. His mind fills with images of his mature, milf girlfriend, her big tits bouncing, her moans of pleasure echoing in his ears. He feels the pressure building, his balls tightening, and with a final, powerful stroke, he comes undone, his hot, creamy cum painting his chest, a sign of his intense, solo release.
