Hey, i've been through the same situation.
What i'd recommend is:
1) make sure there is enough sexual tension built upon your txt game i.e facebook
2) be spontanious and take her for a walk flirt the whole time with small kino escalation
*) buying 2 beer bottles are optional.
3) while u r walking look for a nice dark spot (preferably at a park with a bench) and say dominantly something like "looks like a great spot, let's take a seat"
4) make sure u seat close to her (legs touching each other) and from here u can use the escalation ladder..
I've done so alot, hope it helps.
good luck
