Fic rec:
But you can choose your friends, by
fleshdress.
Ron/Draco with implied Lucius/Draco (so yes, please note the warnings for incest and abuse), smutty but mostly innuendo. And it's brilliant. If you've not read
fleshdress before, give this one a try. And if you have, well, you'll know exactly how clever and moving and endearing her writing is, so you will run over there and read it immediately.
