This is a simple trick I've been testing the last two days, and it's worked wonders. It seems to work better after doing any other magic trick, as she already has your attention.

Start by telling her you're gonna do a little trick, but that it requires all of her attention. Tell her to put her hands together and cross her fingers, except her indexes (pointing fingers, second fingers... fuck, I don't know your language that well). Those fingers will be like a centimeter apart, straight, pointing forwards; do it yourself first and tell her to put her hands like that.

Now get the tips of her fingers, and tell her that this one represents you, and that one represents her. Make her repeat it so it stays clear ("who was this finger again?" etc), play a bit with her fingers.

And now tell her again to keep ther fingers like that, straight, and that now you need her to look at your eyes. Look at her eyes like you're gonna fuck her, usual eye game stuff. Get your face near hers, and start narrating in your sexiest voice, calmly, a scene implying you and her, where you slowly advance to a kiss. It's better if that scene happens at the exact place where you are, with details from things that just happened. "Visualize you and me, sitting at a table in a bar just like this one... Imagine we've started talking about [whatever], we've had a drink, and just there, suddenly, we stopped talking and just looked at eachoter's eyes. I smiled at you [smile!], you smiled at me [she'll be already smiling by now]... And then I touched your face [raise her chin a bit], you closed your eyes... and...".

There's two options here. If she actually closed her eyes and prepared for a kiss, you can K-close here and ignore the trick. If she asks later, say you weren't even trying to do a trick and just needed her attention. Great for you.

If, on the other hand, you can't k-close there, just move back a bit and look at her fingers. She'll look down too, and find her fingertips touching eachother. Say you didn't do anything, it was all her subconscious mind. "Maybe you don't want to accept it, but there's a reason why you did that". She can (and will) try again, paying attention to her fingers, just to have them gently touch eachother in a few seconds. Let her try. "Wow, you must REALLY want that to happen".

In the worst case, you've had extended eye contact, made her obey (dominant!), told her something sexy, done some light kino (hands, face), made your intention clear and planted a doubt inside her mind. So many things with just one stupid trick. Don't tell her, but it works on everybody regardless of their interest in you, and is caused by muscular fatigue in the muscles that move her fingers, causing them to slowly bend. But after all you've told her, she'll believe it's all in her mind, you just need to push things a bit up and you'll be kissing her with little effort.
