Small party at a friends house, just having fun, talking with a bunch of people, I sit in a couch next to this girl and we start talking, I'm not sure how the conversation started (I think that's usually a good sign) but right away we start finding things we have in common (people we both knew, music we liked, food). My friend has a no shoes policy in his house and I notice that this girl was still wearing her boots, so I pick on her a little bit about this and get her to take her boots off, make some jokes about how girls lose their powers when they take their heels off and then mention kind of casually that I used to laugh about people that have a foot fetish but I don't anymore, since something happened to me, this thing a girl did to me (true story) and then refuse to go into details, saying that I shared something really personal with her and that she should share something back with me in exchange. So she tells me this funny story about how her gynecologist was sick and she had to be checked by his replacement who she thought was hot. The conversation keeps on and at some point she is covering with my jacket and sitting sideways on the couch on such a way that my hands would naturally rest on her feet. This was awesome since it builds a lot of rapport, but also because of my previous comment about my foot fetish this is kind of a sexual thing now, I had to focus a lot to keep acting natural while touching her feet.

We talk about this concert that was happening the next day and she suggests we should go together since she didn't have anybody else to go with, so I get her phone number and arrange to call her the next day, we keep talking for a little while and then I decide its time to gather my earnings and go on to talk with other people.

Next day I call her, pick her up and we head for the concert and have a great time together, I get to protect her in the middle of the audience, we dance and there is some kino, afterwards we head for tacos and I am looking for chances to kiss her but the conversation is getting a little bit serious and she is not giving me any chance. I drive her home, park and we keep talking for a while in the car, at this point we had been out together for something like 6 hours, we say goodbye, she gives me a friendly hug and I take the chance to kiss her... She doesn't respond and say something like "oh, this is weird, we are friends" I stay calm and respond saying "I wanted to know how kissing you was like, it sucks when you end up thinking how it could have been", we say goodbye again and I kiss her again, getting a response this time for just a few seconds, we pull back as I say "Now I know" and she gets off the car.

Later I receive a message saying she had a great time, and some wikipedia fact about something we were discussing before, I respond saying I had a great time too, but don't actually mention any future plan to meet again.

The feeling I get is that this was in general a good first encounter but not a solid kiss close and that I should keep acting really casual and try to invite her to a party or something but that if I try to do something more intimate like dinner at my place I might get rejected.

Any feedback would be greatly appreciated.

UPDATE: A few days later I receive a message from her mentioning she ran into a mutual acquaintance, I take this as a major IOI and invite her over for dinner at my place, we had a great time, escalate, no sex yet but things are still on.
