You could've handled the escalation better, as you say it was AFC to be so keen for sex - it is indeed a form of neediness, however I fully empathise as I have been known to act in the exact same manner when escalating!
However this is certainly not a disaster, you created a very sexually charged frame which has now in effect been put on hold.
IF/WHEN she replies, you should send her a message which "leaves her wondering". Something like "Hope you're having fun! Three girls hit on me last night and now one of them wants to see me, you've got a bit of catching up to do

be safe though, don't want an STD" demonstrates HUGE value and also makes her just a little weeny bit worried - Will you still be available when she gets back? Do you like this new girl more? Why don't you care if she sleeps with other guys?
Thinking about someone ALWAYS reinforces the beliefs imposed by the frame of the last interaction with them - you left a fairly POSITIVE frame so now these thoughts will reinforce her attraction for you. Of course, there's no guarantee she'll be thinking about you but this is my opinion your best shot. This is why when she gets back, you should game her from scratch, and escalate from scratch again, do not assume she will be up for it! Good luck.
