That was pretty much an one-night stand, since it seems like she was gaming you more than you her (YOU must scoop HER, not the other way around!).
Plus, if you want to make things last longer.. Play more hard to catch so you will be the exact opposite of an everyday normal guy, for example, if she wants to sit down on your lap.. I would recommend throwing something along the lines of "And whats going to happen if you fart? No way I'm going to let you sit down on my lap, but of course I could sit on your lap" (Heh, say it in a funny way!)
instead of just agreeing and letting her sit on your lap. (Just to give you the idea.)
Texting her 2 times because she doesnt answer seems a bit Try-hard to me.
But obviously, since you nailed her, it means that you had nice gaming there
Great job!
.P.S Your first contact with a phone to her should be a call (In a range from 15 minutes to 2 days), not a text!
