Btw, next time you see her, be really on the lookout for windows of opportunity.
If you get the heavy sexual flirting vibe thing going on phone and such, things have a real potential of getting hot and heavy pretty fast, if you are prepared for them and don't hold back.
That means, next time you meet, have a location ready to bounce back to,
If you do things right you get kisses straight off, and from there on it's purely about escalating sexually, (even better if you meet at an area where this would be inappropriate, so to add on the tension

(being "not allowed" is really turn-on material, a hand on the inside of a thigh in a public place and a knowing look can be all it takes))
But back to now;
Innuendo, and accusation.
Sexual Undertones.
If you accuse her of thinking sexual with enough conviction, she will begin to think that way.. so if you say something that can be interpreted sexually (and of course you do this deliberately) you can accuse her of making the sexual connection.
If she goes with it and starts doing the same, you do the spanking, tell her you ought to tie her up so she doesn't go around freaking people out, or something.
Adapt the classic "Oh my God".. like "Omg, you are so bad,.. I ought to cuff you to the bed and teach you some manners"
And you can do stuff, if you are into heavy flirting and such, where you just state plainly; "You want me to fuck your brains out, I know you do.
You probably want me to do X with you while pulling your hair backwards and biting your neck, etc." (You adapt this to suit what you know she likes, and describe a likely fantasy of hers, using the things she likes. With you in the main role.) Say she likes to be fucked Doggy Style, you say that "I bet you're thinking about me, positioned behind you, right now, ready to fuck you from behind, with you down on all fours,...."and so on.
But really, first if you get the sexual undertones going in the communication, you can gradually escalate until you're describing how you will fuck her the next time you meet, getting her to say how she wants it.
Maybe involving fantasies about public spaces, etc. depending on her, of course, but you can always add a little extra to the Fantasies, since they're "just" fantasies
I'll cut it short here, since I don't know whether I'm starting to repeat myself. But I bet you've got the general idea.
It may help to play around a little with stuff in your head first, maybe write some stuff out and see how it looks on paper/screen.
And if you're going into fantasies, reading some stuff from women's magazines and such (I bet most of them have sections describing such) and taking some of the language therefrom may really help.
You know, just getting the jist of what sort of thing they usually focus on, like how much more they notice details and such.
(I used to read these fantasies written by women when I was younger, which I guess has helped shape the way I think about sex into a more female-friendly type.

)
Hope you find something of use in my ramblings.
Cheers
