[MF] Best friends GF gets payback for cheating

This isn’t a super in depth story but I’ve been thinking about it a lot. So I’ve been friends with Ollie since the start of uni, we are in the same degree and hung out all the time. And at the beginning of the year he started dating Sarah.

The whole time I’ve known her I’ve thought Sarah was pretty hot, she’s shorter than me, with long length black hair and a pale face dotted with freckles. On top of that she often wears shirts with a low neckline that really tests me to not stare at her cleavage

Anyway, one night Ollie went to a bar and ended up hooking up with someone from one of his courses, she told her friend who happened to be a good friend of Sarah. A few days after that had all happened (without my knowledge) I got a text from Sarah asking me to meet her at her place. Tbh I actually said no at first because I was supposed to meet my girlfriend later and I wanted to go home first, but she said she was in a really bad place, I didn’t really understand why she wouldn’t ask one of her friends to come over, but 20 minutes later I was there.
