I massage his balls. They start to swell and his cock starts to drool. I play with his drool and I rub it all over his cock. It drools big globs. I use it to keep it slippery & wet. I milk more & more rubbing the precum all over his cock. It gets very wet & slippery. It is making a mess before it cums. I work on it paying special attention to the head. I make it drool nice thick drops & strands from his hole. Precum stretching from his cockhead to my fingers, etc. I tease it and massage more precum. I add lubricant to the mix making a very sloppy cummy mess. Big cummer.
