I Want Your Fest Recs

So, there's too much fic and not enough time (as always) and I have a new strategy this year when it comes to fest reading. I started working my way through the Snape Potter Daft Day Smut Swap, but then I realized I've hardly touched Merry Smutmas, or HD Holidays which I have not looked at since the summer pre-DH round!

So, I'm asking you, my dear friends, to rec me what you liked from these fests, or any other recent fic that knocked your socks off. You know what I like: any combination of Harry, Draco, and Severus, in-character, graphic sex, and plot. Point me at the good stuff.
