You will want to remain unreactive no matter what. Pretend as if you never went in and just keep talking. Get her more comfortable to touch, compliance test and try again later. One thing I heard somewhere that will always stick, "If she wont hold your hand she wont kiss you."
Great responses, but I usually approach this from another angle, when a makeout window is there take it. A few things to remember if you go for the makeout:
Get the sexual tension high.
Get her face close to yours, but tease her. Don't kiss immediately.
Make her want the kiss.
When you see the window take it, but pull away FIRST. This is the most important part about makeout game. This makes her crave more.
Move and lead!
Try to get her outside of the venue and solve logistics on the way.
Once outside if you cant solve logistics, number close.
This is what I did last night in my FR. Text'd her today with a sweet response. Sucks she's from out of town, but surely she will hit me up when she's here next time. I gave her a wild experience that she will not forget. Next time she knows I will escalate to sex and there's nothing wrong with this, I left her wanting more and never became the chaser. Women want and crave sex, it's our job to be the type of sexual man that can give it to them the way they want. I believe Chase has a post on this that there are two types of pulls women want: The sexual fantasy where you take her quickly and sexually and the prince charming method. I prefer the type of girl that likes the first one.
I have done this once before and received a text right when the girl was returning to town to hook up. I didn't because I'm not allt hat attracted, but we both know where it would have led and she is OK with that. This is also in my FR.
