rarepair recs?

I have recently become addicted to interested in rarepairs (well, run out of reading in Remus/Sirius and Harry/Draco), and it occurs to me that there's a lot of good stuff out there that I'm not reading cause I don't see it. This is wrong. If there is good porn, then I should be reading it.

So, you lot, being perverts in various different ways, would surely have some recs to give me? Your favourite Draco/Neville, perhaps? Ron/Pansy? Lucius/Snape?

Come on. You know you have it. Give it to me.
