Was it just sympathy or did they really like me?

I am 16 and I went over to this girl's house with my family and met theirs. I had never met this girl but she had a friend over and while everyone else was upstairs we just hung out downstairs and talked, had a good time. One of them said I was cute. Later we were driving around town and one of them asked me if I had ever had my first kiss and I told her no. She would not believe I was telling the truth but then said well you're going to get it tonight. So as we drove to my house both of them gave me a kiss, I gave them my number, and I left to my house. Well they are coming over to my house today and I don't know what to do. Give me as much advice as possible.
