Same situation I have experienced....
I was in a same situation once, with this girl that I really wanted to get to the next level, well before bubbling into her friend zone, just before that, because probably that's where you're going if you don't quit teasing her like if you where relatives or friends.
My experience with that chic was that we were playing rude, but I use always this approach, I said to them let me tell you something to you in the ear, and then BAMMMM give them a softly bite in her ear, then approach her to her eyes and directly to her mount and kiss her.
Good luck
