Harry potter multiple mates

[Guest Emma]

I can only remember minute details but, Harry has between 9 and 13 mates, he's some kind of magical creature. I know that Lucius, draco, Snape, Bill, and Charlie are some of the mates. I cannot find this fic again for the life of me and any help would be greatly appreciated. One scene stands out where 90% of his mates are all in a room together and harry is having sex with them one by one.

Sort of sounds like Shiloe, it can be found on this site

Could be the Mimicker (I think that's what it is) on Ao3?

I know it’s super late but I think you’re looking for Vorago in ao3
