Rex, alone in his room, decides to indulge in a private moment, stripping down to reveal his massive, throbbing cock. He strokes it slowly, feeling every vein, before picking up the pace, grunting with pleasure. His big dick glistens with pre-cum as he edges closer to release. Finally, with a loud groan, he unleashes a torrent of cum, coating his abs and chest in a sticky, messy display.
