this technique has not failed me yet:

First you start with an Altoids mint in your mouth. Start at the tip. Slowly lick your way around it, giving extra attention to the slit. As you swirl your tongue around him slowly work your way down the shaft. Once you've worked your way all the way down, and you have it all in your mouth, exhale deeply as you slide your mouth back up his shaft. The coolness of your breath and the tingle of the mint will drive him wild. Also it helps if you gently massage the area directly behind his balls with your first two fingers. He'll blow such a load you won't be able to swallow fast enough. Hope it helps.........
