I've be flirting/fucking around with a married co-worker for a few months now. I initially approached her thinking she'd cheat on her husband because she's been hooking up with this other guy who is loosely in our same social circle.

As far as my involvement with her goes, we've not had full blown sex, but my heavy flirting and Kino escalation has led to some pretty hot contact (she let's me play with her tits and ass, usually, but not always, through her clothing). She'll also sometimes wears fishnet tights and come into my office and spread her legs for me to see her pantiless crotch as she flirts with me.

I know you're asking: why haven't I fucked her yet? Well, it's not for lack of trying. She seems to get off on flirting with me and this other dude, but pulls back when it comes to actually fucking. Says she feels guilty about "cheating" on her husband (as if what's she's done already is not cheating). Kind of a tease/brat who loves the attention. She tried to shit test me and make me jealous by telling me how she might finally fuck the other dude, but I told her it surprised me that she hasn't fucked him already. Although I admit I was jealous as hell. Naturally, i want to be the guy she wants and it makes me jealous to think she's fucking around with some other dude. She's probably teasing him, too. Funny that I don't get at all jealous of her husband, just the other dude.

So basically she loves teasing, but she also loves to get close to the edge.

So here's my question: what's should my broad strategy be to bed her once and for all?
