I really had to go searching for this one. I tried to find one of a pairing that I haven't done before. It was hard and took a while, but I did it.
Well, it's a Snape/Voldemort, and it's called Bodies are For Taking. I know very few Snapedemort fans, and am not really one myself, but I have to admit, this is pretty good. It's only one chapter(but an immensely long one), and somewhat AU. Actually, the only part that's AU is that Dumbledore is alive during the Battle of Hogwarts, and that Snape is screwing Voldemort. Then again, the way it's written, there's almost no way to prove it didn't happen.
And yes, it's rated M. So expect explicit sex scenes(and Voldemort is totally into S&M). But as for everything, I really like the creative spin the author took on it. It's well written, but I couldn't blame you if you outright refuse to even click on the link, since it's *Snapedemort*. You know, I'm not even sure if that's the term for the pairing. It sounds like it would be, though...
Warning: There is character death. Just thought I should say that.
