Smutmas - any guesses?

I was checking my friends list before bed, and a post by coffee_n_cocoa caught my eye.  She's asking people to guess what fic they THINK she wrote for Smutmas.  That intrigued me.  And then I saw other people posting lists of guesses.

So I'm curious... what do you guys think I wrote?  I'm curious to see what you guessed, and just as much, WHY.  And if you already KNOW what I wrote (because you beta'd, test-read, or live with me, you don't get to guess here.  :D

Humour me.  :D
