Found! Random Alpha does not like humans

[lanenk]

So, I think this might have been a five times fic but I can't really remember, probably Derek/Stiles. The scene I do remember is that a visiting Alpha (who is really old fashioned) shows up at Derek's house unexpectedly and stiles has to act submissive/servant like. He did it without prompting because he had read about it and he didn't want to cause trouble for the pack.

Thanks
