Well, the concept itself is pretty simple. You aim your lips for your partner's lips, move in slowly so as not to knock your partner backwards, and voila...the kiss!
Honestly bud, there really isn't much more we can say about this. The reasons we don't discuss technique around these boards are twofold, primarily because it can get us into all sorts of trouble; and because, well, everybody's different. I can tell you how I like to be kissed, but you sure as hell won't be kissing me. I can tell you how my sweetie likes to be kissed, but you'd best not be kissing her either! You see how it is? Any tips you are given by any of us will mean precious little to you and your partner when it all comes down to it. The only way to figure it out is by asking her, and you're going to have to get around to that sometime.
My advice for you, limited as it may be, would be to play it by ear. Who knows, maybe you'll be too nervous to pull it off or the timing won't feel right anyway. Don't let yourself be psyched out by something that really isn't that huge a deal to begin with. Enjoy your time with this girl, do what comes naturally, and let us know how it goes. Good luck!
