The twins, their uncut cocks hard and leaking, start by rubbing their bodies together, feeling the heat and friction. One twin takes the lead, pushing his partner onto his back and straddling him, their cocks sliding against each other. He leans down, capturing his twin's mouth in a hungry kiss, their tongues dueling as they grind. Breaking the kiss, he moves down, taking his twin's cock deep into his throat, the head pressing against the back of his mouth. He swallows, his throat muscles milking his twin's cock, while his own dick leaks pre-cum onto his twin's stomach. They switch places, the bottom twin eagerly taking his brother's cock into his ass, arching his back as he's filled, their bodies moving in sync, fucking each other hard and raw until they both explode in a mess of cum and sweat.
