What happens when you kiss your bestfriend?

We have been best friends for 5 years now and we have always been kinda flirty with each other like holding hands when we walk and holding eachother butts lol but recently we kissed for the first time, it felt so right she liked and i did too and she didnt want to stop kissing but at the same time we are both girls so now im confused because i was drunk the first couple times we kissed and hooked up and now sober we kiss all the time i dont know if this means she likes kissing me because she asks me all the time for kisses and dont get me wrong i dont mind it at all because i like kissing her but i would never go beyond kissing and i dont think she would either but i really dont know what she feels about me. she always tells me she loves me and im her bestfriend forever and by the way she has kissed her other friends on the lips before but she has only hooked up with me and whenever i kiss her noww its just lips no tongue that was only the one time when we were drunk. but i need to know if she likes me or she just likes kissing girls and experimenting i really dont know im confused someone pleaseee help mee!! thank youuu
