I've been in the same situation many times, and am in one now with a girl at work. I'm going to fuck her in the disabled toilets this sunday at work
I've been setting her up for this moment - last Sunday (I do one day a week), I tell her, Gamble: “did you know one in six people have sex at their work place?” (This is true, it was in the guardian).
HBworkgirl: “is that a hint?”
Gamble: “No, I’d never do it with a girl like you” (and walk off)
HBworkgirl: (Calling after me and blushing) “Why not…!?....joking…(embarrassed).”
^Now that IOI = permission to fuck her!
Anyway, how did I get there? Well, you’ve done bloody well not to perv over her like everyone else. You’re the exception to the rule. Now, you need negs. She’s in demand..so? YOU ARE THE PRIZE. Neg her about anything. You don’t need other people to make ones up for you.
At some point get her to start qualifying TO YOU. Eg:
“So the lads tell me you’re kinda cool, but I’m not too sure personally (play punch-kino). Tell me, what makes you special?
-or-
Is there more to you than meets the eye?
-or-
So what are your three best qualities?
At the end calibrate to see what to do next. Maybe qualify followed by neg (push-pull). Something like:
“Ah, I like that in a girl (look down upon her while saying this, YOU RULE HER)…you know, you’re kinda cute (lean in and be romantic)” Then just before climax, nudge her away and say “But you’re not adventurous enough for me, I don’t think”.
If you play it right, she will disagree and say she is…keep this going and just escalate. You will have her eating out your hands.
Hope this helps
