Accidentally Mated (Larry Stylinson) COMPLETED

Louis has just presented at the age of 24, becoming Omega out of nowhere.
He looks completely different, he's even changed personalities slightly.
Harry is an Alpha and meeting Louis as Omega confuses him from the start. He smell gorgeous, looks pretty, but Harry's straight. So it Louis. Well, he thought so anyway.
Things get more confusing and crazy when Harry accidentally mates with Louis, and things change.
Is it for the better, or worse?

There is major smut in this storyline, and I have started chapters with a warning.

(Is on Private so will need to follow) x

AN/ Zayn is still in One Direction in this story.

Also. If it's not COMPLETELY obvious, this story is from Harry's POV...
