Asking this question feels kind of pathetic, because it means I've either completely lost my erotica writing skills, or that I don't know how sexual tension between human beings interacting in person works anymore!!

But enough of me being embarrassed, here's the problem: I'm trying to write a script in which the speaker meets a gorgeous woman in a bar, is attracted to her, and ends up eating her pussy in the bathrooms. I'm pretty sure I can write a first meeting, and I'm pretty sure I can write a decent pussy worship scene, but I'm not entirely sure about the in-between.

I've got no idea how to get either party to start showing interest, and I've got no idea how to develop that interest or show that it's mutual. And I know that if I want a "nice boots, wanna fuck?" scenario to work, I can't just go from "nice boots" to "wanna fuck," y'know what I mean?

TL;DR - I don't go to bars or flirt with people at bars, how do I write people doing that?
