Hey guys

I broke up with my LTR a few days ago and so did a female high school friend. She didn't take it too well, platonically I care about her, and her boyfriend was a close friend of mine and he went insane and fell off the face of the earth.

I've been staying with her a few nights this week, drinking and talking about our life's problems. I told her I wasn't going to fuck her and didn't want to.

Last night we hung out with a work friend of hers and got drunk and watched a movie. We all decided to sleep in the same bed. I woke up after being asleep for about half an hour spooning with her. she was grinding on me and grabbing my arm. I didn't think anything of it and kinda just laid there expecting her to stop sooner or later.

She didn't. I was fairly drunk too and it progressed into fucking her ass choking her while her friend was asleep 2 feet from us. It wasn't a very good experience honestly. You can't caveman if there's someone asleep next to you. After about an hour I came in her ass and and she came a few times. I kinda roll off and try to fall asleep laying with her. She kinda kicked me off so I just turned around.

This morning I asked her "what was that? we agreed no sex. now you seem pissed at me."

she replied with "oops I was drunk and kinda just want to pretend it didn't happen"

I said sure, sounds like a plan.

She apologized and asked if that was okay. I dropped it.

I guess I'm just asking what the fuck happened?

I assume her wanting to pretend it didn't happen was just hamstering and thinking she'd be seen as a slut. how should I progress from here?

TL;DR: drunk hookup with platonic friend (my choice) in same bed as other platonic friend. Friend said she was drunk and wanted to pretend it didn't happen. What happened and how should I handle this?
