Got drunk

I got drunk and made out with my bestfriend and gave her like 4 hickeys on each side of her neck, and I cant believe it happened. (I am a girl, and never been with another girl before) This is my second time getting basically shit faced, I've never looked at her in a sexual way. We both were just desperate and havent been in a relationship in a while. I can't believe it. Im so embarrased
