My best friends boyfriend took my anal virgintity [FM] (BDSMish)

This is my first time writing something like this, so go easy on me!!My best friend, (we’ll call Catie) and her boyfriend (John) go to school in a different state. I miss them, and they flew up and visited me for my birthday.

Fast forward to my birthday party, and we’re all super drunk and playing Never Have I Ever. When it gets to me I start with “Never Have I Ever been fucked in the ass”. Catie mumbles something about me missing out and takes a shot. She comes up to me after and starts telling me I should try it, going on about how great John is in bed, etc. I had just gotten through a nasty breakup and was getting jealous and upset. She saw it on my face and whispered: ” John thinks you’re cute, it’s your birthday, go have fun”.I asked her if she was sure. She nodded and waved him over to us. After all three of us talked for a bit, she asked to go to sleep in my spare room.
