The first time it happened was an unexpected accident. What about the second? Beckett is living at the loft after the explosion and subsequent fire in her apartment. Will they grow closer together during this time or will they learn that one's company and two's a crowd?

If you're searching for forever, I'll be waiting; come find me. Caskett semi-AU canon from Nikki Heat's book release (2x05)

She doesn't understand what happened between them, why it all went south. And at the touch of a hand it all comes rushing back to her, a wave of heavy emotion hitting her directly in the chest. Her eyes fall shut and she knows she's showing her hand, her heart, but god, she could have sworn they were headed somewhere five months ago. Probable Cause (5x05) AU

"Detective Castle, this is Katherine Beckett, famous mystery novelist with 26 bestsellers to date, perhaps 27 soon if this all works out. And your shadow for the foreseeable future." AU.

Season 2 AU. We all remember the Season 2 finale. What if Beckett had ignored Gina showing up, bitten the bullet and said what she had intended to say? Castle, Gina and Beckett at the Hamptons. What could possibly go wrong? More to the point, what could possibly go right?

'There was a story, always a story, and she was only here temporarily, but she wanted to know his, wanted to invest in his. And hadn't she just discussed yesterday with Decker that fraternizing with fellow recruits was a bad thing' AU for 8x15, 'Fidelis Ad Mortem'.

"Those texts, Kate. Those damn texts." A three-part prelude to 8x09. Smut ahead.

Knockout AU where no one is shot. "And that is the biggest piece of crap you've said so far," shouts Kate, pointing her finger directly at his chest. "Why don't you just say it?" Taking a step closer, she says it again, adding more taunt to her voice while their eyes connect. "Why don't you say it, say it while I'm on two feet and not being shot at!"

The first time they used her handcuffs in the bedroom. Post-episode tag for 5x02 "Cloudy With A Chance Of Murder."

Takes place right after 8x08 (Mr and Mrs Castle) when Castle and Beckett disappear in the bedroom. It starts with fire and playfulness but works toward something more emotional.

Castle's had a few watches, down the last few years. Beckett has one watch. It has, according to her, been hers for the last five years. He's never seen her wear another. And now it's in pieces in her wrecked apartment.

While in Atlantic City having a girls' weekend with Kate, Lanie, and Jenny, Alexis and her best friend Paige find themselves suspected of murder. My entry for the 2015 Castle Summer Ficathon. The cover art was designed and created by the incredibly talented Angie (@dtrekker on Twitter). Rated 'T,' but the rating might change.

Oh god, her legs. He could not stop staring at her legs. Set around mid season four.

This is not a place where St Nicholas would distribute presents, though it might be where his demons let off steam. Danger abounds here: hot, heavy and welcome. This is a club where dreams can come true. Of course, dreams should only be a one-time experience... See CH1&3 A/N for Warnings Before Reading and note M-rating. Castle belongs to ABC/Marlowe.

Prompt for the summer kink meme 2015 "Emotional sex during the night of always. So maybe their 2nd or 3rd round. She tells him how much he means to her etc. So some cute, fluffy, hot smut."

Written for the Kink Meme over on LJ. Prompt-sex to conceive. They both just want a baby.

'He had weaseled his way into her case and eventually, needling her for information while dangling his own in front of her had led them to an agreement, an even trade that turned into so much more.' An AU spin on Castle's time working as a private investigator.

"He's been a husband three times now, but she's never been a wife, not a participating one anyway, and Castle intends to make every part of their marriage special and exciting. After all, they did promise each other to never be boring." *An AU entry for the Castle Winter Hiatus 2014 Ficathon.* Cover Art by the talented (XFchemist).

Sometime in the next ten minutes she is going to kill Lanie, because she is currently perched on a bar stool in a Miss Santa costume. Unashamed Christmas fluff, with little plot and less excuse.

Fans think that the 1st time Castle and Beckett 'hooked up' was after "Always". However, there was one time before that, but they'll never admit to it. Even to each other. NOTE: After 'Pandora' but before '47 Seconds'. Now rated a (Hopefully tasteful) 'M'.

"There will be a later, there will be plenty of time to do everything she's ever dreamed of with him, but now – right now she just wants him." A continuation of the 'Always' deleted scene.

Post 6x17 She follows him willingly into their bedroom, letting him tug her along and watches as he pulls back the covers and fluffs her pillow.

When Beckett can't seem to keep her thoughts under control at the precinct, it's Castle who has to step up and fix the problem... Not that he's complaining. Smut... total, unashamed smut. Consider yourselves warned.

Castle and Beckett in undercover positions of the naughty kind. 6. Let's Just F*** It Out

The reality of spending an entire week in the Hamptons with Kate already has him completely on edge, but when she casually drops her hand to his leg, fingers tracing tantalizing patterns on the inside of his thigh, he's not sure they're going to make it to the beach house without him crashing his car into a ditch. Complete.

My version of Castle and Beckett getting together, one of many. Set: S4, before "47 Seconds". At Beckett's place after a poker game with Espo and Ryan. Now the Gang has left and Caskett is alone. When a small spot changes everything.
