Surprise sex with my best female friend

I am female 22 yo. I had several boyfriends since I was 15 and a lot of sex. After my last break up my best friend Leah took me out for some drinks. We got a bit trashed and went back to her house. When we arrived she opened some wine and she put the TV on. After a few minutes she moved closer to me on the couch and put her head on my shoulder. Then suddenly she began to rub my leg and her hand slipped under my dress and she rubbed my pussy over my panties. I was like Leah what are you doing? She goes just relax. OMG it felt so good. My panties were getting wet. I opened my legs a little and she slipped her hand inside my panties and began to finger me. It was amazing and she made me cum real quick. Then she licked her finger tasting my pussy juice and then kissed me. It was so passionate. We had never done anything like it before and I had know her for 5 years. As she kissed me she felt my breasts. I started to touch hers and her nipples were hard. Then I move down to her pussy and realized she wasn’t wearing any panties. Her pussy was soaking and I slipped my finger in her and she moaned softly. Then I got two fingers in her. She kept telling me to go faster. Eventually I pushed her back on the couch, lifted her dress and rubbed her clit with one hand while fingering her with the other. She was moaning so loudly now I made her explode. Then we cuddled for a while in silence until she took my dress and panties off, I wasn’t wearing bra. She undressed and moved me back on to the couch where she got us in a 69 and began licking me out. I had never felt like that before. I stuck my tongue in Leah’s pussy and we liked each other t another explosive orgasm. Then we lay together to get out breaths back.
I told her that after all the years we had known each other I didn’t know she was gay. She said she wasn’t gay but this just felt right. I asked if she had sex with other girls and she said only some kids stuff when she was younger and a bit more with a couple of girls at a sleepover when she was 13. I told her me too.
Anyway that was a couple of months ago and we have done it many times since then. Now I think I am falling in love with her. I think the feeling is mutual but I haven’t been brave enough to tell her. I never expected to be a lesbian but I guess I am.
