Unexpected allies (lokixreader pov)

This is my first pov story about the main character (you), your friend Thor and his brother Loki.
You come with Thor to Asgard for the first time where you spot a strange man hiding in the shadows during a ball. You follow the man and discover someone you weren't expecting. The story begins..

the last part contains smut '(lokixreader) but i will write an alternate ending for those rather read fluff.
