My first thought when I read the content/warnings and cliche area was "OMG IT'S CHRISTMAS AND MY BIRTHDAY ALL ROLLED INTO ONE!!!"
Then I scrolled down and saw the art (I cheated, I know) and thought "OMG THERE IS A GOD AND HE LOVES ME!!!"
And all that was before actually reading the fic, which was amazing and delightful. I love that you have Harry as a reluctant owner, saying he's not a very nice person even though he's secretly planning on basically ending his own life all the time.
Severus' inner voice was so very IC, even while he was getting his punishment. And seriously, all of that was hot. You managed to make him enjoy corporal punishment while still having him IC. That's an accomplishment.
*claps*
And that art is seriously amazing. My eyes continue to be draw to his lovely profile, then those bindings, then the lovely reddened ass.
