Jack's masturbation marathon begins innocently enough, but soon spirals into a frenzied, cum-soaked odyssey. He's a man on a mission, his hand a relentless, friction-filled machine. His breath comes in ragged gasps, his body glistening with sweat as he chases the elusive high. The room is a whirlwind of motion, his hips bucking, his cock slamming into his fist as he edges closer and closer to the point of no return. Finally, with a guttural roar, he finds his release, his cock pulsing, unloading a torrent of hot, sticky cum onto his heaving chest.
