I have an awsome idea: ask her (at an appropriate moment; like after the date) if you could kiss her! No kidding; she will be really impressed that you showed her that much respect to ask her first. TRUST ME she will think very highly of you (and probably brag about this to her girlfriends with "fast" guys). This WILL work, as long as you really mean it and don't appear to mind if she turns you down (she may do this at first; but that impression will still be there *wink wink*).
That's the most straightforward approach anyway!
