I've used this 3 times now, and every single one resulted in success... in fact, it left the girl wanting more, so it's really good for push-pull:
You: Talk talk talk
Her: Talk talk talk
--Then, when the conversation comes to a pause... or you can interrupt her, whichever...---
You: Hold on, I gotta see something
--Go in for kiss, SLOWLY, **but STOP just before your lips touch.** She will invariably close the distance---
--Make out for a little bit--
You (pulling back): Ok, that's all I needed
And continue the conversation like nothing happened (I use this point to jump ahead in kino escalation... if she's comfortable kissing me, she's comfortable with my arm around her shoulders, waist, etc.)
The second time I used this, the girl pouted and asked, "That's it?"
The third time, the girl saw what I was doing as I was doing it, actually grabbed me by the sides of my shirt, and pulled me in into the kiss
This is great if you're still a newbie-ish PUA (like me) or if you're just not feeling that creative.
