Pick Up Artist VH1 - Mystery sits in his living room with a woman

Mystery sits in his living room with a woman, showing her some short comedic home movies. They are in C3. He puts on some music, lights up the hookah and they share smoking it. He inhales the smoke from the pipe, and then exhales it into her mouth. They do this several times.

Sharing intimacy by holding each other and kissing, he now progresses their kissing into foreplay. Both aroused, he takes her by the hand, leads her into his bedroom, hands her a box of matches and says, "Here. Light the candles while I find the incense." He then says, "Can you close the blinds for me? I'm going to wash up." A minute later he returns. "Why don't you go wash up while I light the incense," he says to her, pointing out where the bathroom is.
Building the seduction scene together in this way is similar to the way long term couples regularly do. Such ritualistic behavior is familiar and comfortable.

In case it has not been made clear up until this point, do not make this move before you have properly qualified her and built comfort with her. If you do, it will activate her anti-slut defense or cause her to get buyer's remorse, or both.

Further complicating matters, if the window of opportunity is open and you miss it, it seldom opens twice for the same bird. She may go home and backwards rationalize all the reasons why it didn't happen. So, in the interests of practice and rapid improvement, when in doubt, just escalate. Even if you're wrong, it will still improve your calibration.
