July 4th BBQ Madness!!

So my boy who lives upstate NY has a BBQ for the 4th. My brother lives 10 min away so he rolls through with his wife. 30+ people. Before he comes, he texts me and asks if his wife's best friend can roll. Sure! It's not my house but I am like family..and it's a chick. So they come through. A good time is being had. Sis in law and her homie are sipping on Coronas. I am drinking tap brew. My boy's bro-in-law opens a bottle of Patron Silver and pours appr 15 shots. My Sis in law's friend has 1. I am now sipping on vodka. She comes over and starts bs-ing/flirting. Asks me to make her a drink(vodka/cran) Now, shots of vodka get poured. She has 1. (Quick recap-she has had: corona/vodka-cran/tequila/vodka shot.) She is hanging near me/flirting and people are getting tossed in the pool. She gets tossed. Comes out laughing and says to me that she had "pool" clothes and would have jumped in herself. I ask her if she wants to change. I take her to the bathroom near the playroom. She changes into another pair of shorts/bikini top and has a wifebeater in her hand. It's just me and her and we start kissing like 2 people in HEAT! So we go back to the back yard and we are both doing our thing and I am sitting near the garage. She comes and sits with me and I grab her hand and take her into the garage. Kissing! I toss her onto someone's BMW hood. So I ask her to come upstairs(I was spending the wkend so I stay in the usual room which is my boy's daughter's room.) We get to the room..jump on the bed....more passionate kissing....I reach under her wifebeater and she says, "just take it off!" I do. We are all over each other and my hands are now down her pants. As moist as the pool! We are getting heavy(but her and my shorts are on) and my boy's wife walks in!! WTF(is what she said!) I cop a plea.....nothing happened!!! She buys it after a while. The girl throws up in the sink!!! Ok..nice party. But I was kinda digging this chick and want to check her out again...not just to seal the deal. She has no kids/never been married/job and I am the same! Push up to just seal da deal or see what/where this takes us?? Opinions pls!

She lives in the upstate area(Orange County.) I live in Bklyn. So I would really only get a chance to see her on the wkends...
No flicks. I had my camera but as the BBQ got a little crazy, I decided to not even take it out.
We didn't even excchange #'s but I asked my brother to pass mine along to her. I actually think that she is a bit embarrassd at what happened...especially the throwing up part!
