Why did my friend wanted to kiss me?

me and this girl (I’m a girl) have known each other for a year now and when we first met she liked me but then backed off because she didn’t want to during our friendship months later we were hanging out and we were talking about relationships stuff and I told her I didn’t have my first kiss yet and she said if I wanted her to be my first kiss I said yeah and we did after we got home we were alone again and she wanted to kiss me but I backed off because there was a camera next to us she really enjoyed the kiss but I don't know why she would want to kiss me again after we got home does that mean anything?
