Firenze/Snape or Firenze/anyone is a secret kink of mine, and your portrayal is perfect. I love the way you've written both of them.
I also enjoyed reading about Firenze's room, and the way DD had created it. What a perfect spot for Snape and Firenze to get to know and love each other. Their loving is hot, but tender and sweet at the same time, something that's not often written anywhere nearly as well as you've done here.
And the pictures ... they're beautifully drawn. Absolutely gorgeous. Delicious icing on a mouthwatering cake.
Thank you both for sharing such a lovely presentation. :-)
