A/N: I promised you Christmas-fic, didn't I? :P Anyway, this is fluff. Just so you're warned. Maybe not in the strictest sense of the word but to me, it's close enough. Hope y'all like it and that you had a great Christmas, or still have one if it's not over yet ;)

Tomorrow's prompt: Castle and Beckett living together. (It might take a little longer since I'm making this a proper one-shot. But it'll be up before midnight my time, promise.)

Caskett, Christmas

Beckett walked to her office, grumbling slightly to herself. Castle had called her and told her to come here. You know, just like that. There wasn't even a good reason for that.

She opened the door and her mouth fell open. Of course. How could she have forgotten the date? Christmas. She disliked Christmas, ever since her mother had died. It had been their holiday and now, it dragged up too many memories for her.

Castle stood there, next to a huge Christmas tree, seeming to be pretty pleased with himself. The tree was gigantic, it was just like Castle to over-do something this way. It definitely was pretty, but Beckett just didn't want to be reminded of Christmas.

He apparently saw that she wasn't comfortable (he always saw everything...) and walked towards her, probably thinking about hugging her. She stepped back and he got the hint.

'What's wrong, Kate?'

She didn't quite want to tell him.

'Okay, so we're playing this game again.' He sighed. 'This reminds you of your mom, right?'

'How did you know?' Seriously. He was better in deducting than she was, and she was a detective, for crying out loud!

'You were playing with your ring from the moment you saw the tree on.'

Damn, he was good.

'It's a shame, though,' he sighed.

'What, that I don't like Christmas?' He stepped closer to her and while she noticed, she pretended not to.

'That too. But the mistletoe above us will now go to waste.' He pouted and she smiled somewhat. Wait, mistletoe?

She barely had time to look up before he snaked his arms around her waist, pulled her towards him and kissed her. She was tired of fighting it. So she locked her arms around his neck and kissed him back.

'That was definitely the best Christmas present ever,' Castle told her when he pulled back.

'It's not over yet, Castle.' And with those words, she pulled him back down and kissed him once more. She would never, ever deny herself this again.
