Last night I went to a party with some friends and sometimes I feel a little timid but tonight was not one of those times. It was an okay party with some hot woman that I wanted to throw some game at. I wasn't really concerned with looking like a jackass either I went up to these two girls on their phone and mentioned that they looked bored and I was here to make their night a little more exciting (cheesy and weird I know but I had a little bit in me). They laughed at what I said and eventually I started talking to one of them and we ended up talking on the balcony and even playing BP together. At the end of the night nothing really happen, we were talking and laughing, enjoying each other but I didn't really know what direction to go in to do a little more than talking.

I'm great at opening and talking, but finishing is something I need some advice on.

TL:DR: need some advice on how to take a playful conversation with a woman at a party to something more.
