Pretty much what the title says. Yes folks, I'm looking for wing!kink stories. Wincest, Destiel, Sastiel, possible J2?

But here's the thing...I'm not looking for just pwp stories where Dean (or whoever) plays with Cas's (or whoever's) wings and sexy times ensue. I'm looking for actual plot in the fic. I really love fics which make a lot of reference to the anatomy and behaviours of wings. For example, I read this Destiel fic once where Dean manifests wings and since he's never had them before, he can't control them and as a result he unconsciously displays them in really aggressive, dominant ways, especially towards Cas, where his wings aggressively show his intentions to mate with him ( http://archiveofourown.org/works/1456621?view_adult=true )

Basically, I'm looking for fics similar to this (I have no top/bottom preferences), but as I know chances are small in finding them, I will take any wing!kink stories provided it has a plot, and it isn't just pwp (however, if it does have porn, I'd love it if they focused on the wings a lot; like the way they're meant to be the erogenous part of the character's body (if you know what I mean ;) )

I know I'm being really demanding, so thank you to anyone who finds me anything, or even if you actually managed to read through the whole thing! ^^
