So I've tried this two times and it's been a massive success. I'm going to try this again and probably keep doing it for a while. Once I know it's on, she's giving me all the signals, I start the sexual banter and if she's on then I go for it.

What I do is I'll start talking about things like wrestling, and then get really into it, and make it all cute with a subtle hint of sexual. Something like "Oh I would totally pin you down, you have no chance darling" or something like that. If they're into you they would go along with it. From there I would look into her eyes, make my voice a little deeper, put on a smile and say "well that may be the case, but I bet my tongue could beat your tongue in a wrestling match".

The last time I said it the girl kind of put her chin down and looked up at me with this huge smile, the girl before her just bit her lip and gave me those "fuck me" eyes. From there I would just go in for the kiss.
