So what are some good ways to tease a girl?

Im talking about getting a girl to want you more than you want them.

I've been on two dates with this girl, and we havent kissed yet. First date didnt touch or anything just walked around the beach and on the pier, and went for ice cream.

Second date we watched a movie, then went to dinner, got to the beach around 8ish, i finally grabbed her hand with no rejection. So we then walked up the cliff, stood against a fence and just watched the water and talked. So finally i moved behind her wrapped my arms around her and kissed her neck a couple times, and she seemed to go crazy and didnt keep her hands off me all night (she would put her arm around me or try to hold my hand). So it was about 11 we went back to my house is watch superbad, and instantly we both cuddled on the couch it was great and she went home around 1am, i walked her to her car gave her a hug and a kiss on the check.

So the bad new, she has an open relationship with her boyfriend when i asked if she was single, she didnt seem to be too happy with it and told me that she was completely into me and needed to figure something outs. The situation with the bf is that they dated last summer and went to different colleges 6 hours away so they only saw each other one a month or so.

How can i make sure i win her over and get her to want me more.

please help im really falling hard for this girl.
