Seriously, this just isn't fair. She so rarely has a day off in the middle of the week, and instead of spending it lounging in bed with her, all her delicious nakedness aligned with his, he has to sit through Black Pawn meetings. Happy Birthday, AC!

"Castle." She breathes, her eyes dropping, roaming over his face, like she wants to devour him and she did say dessert.
