in reply to goesthedistance there isnt so much a secret as practice. It is controlling the orgasm and controlling the cum. Confidence is the biggest part.
I find the best thing to do is fuck the girl to the point of orgasm and then stopping, do this a few times untill you really ache! THEN go down on her to get her near (stops her drying out cos chics get bored too!). Talk to her, tell her she is so fit you want to cum in every part of her and all over her (if she is a dog they go nuts for this and it also helps your delay-cum practice for when you get a fit chic!) and the trick is this:
Orgasm just a little (THAT is the hardest part, doing it just a little as there is a balance) and you will fel a twitch building from your spunk muscle - let the orgasm subside but the twitch is still held with a chamber full of gentlemans-relish! Dont let it spurt like a reflex but a controled lob release like making your stiffy bounce (you can totally control it, bit like trying to stop a piss midway or squirting out the last bits only cum is thicker and more controlable).
I prefer to shoot the first one in her mouth, the second after fucking her a bit by pressing tip against her ass and letting some go in there, then fucking her again and repeating it, then oral the girl to the brink of orgasm and by then instead of being fucked you will be on bring of shootingyourself and can cum at same time!
One big thing, it takes one INCREDIBLY fit sexy girl to make you do any of this thru oral alone, remember porn flicks/vids are staged, fluffers and stunt cocks!
The biggest mind-killer of all this is you WILL over shoot or go too far the first two to fifteen times and no one wants to perform shortgame infront of a girl - answer? Brush up on them oral skills lads! Munch that rug!
