Countdown (3x17) AU from when Castle defuses the bomb.

"Castle." His lashes rise, nearly graze hers in their ascent. She's never been this close before and yet, somehow, she still doesn't feel close enough, still wants so much more. "I love you."

The song says: "The future's so bright I gotta wear shades". Yeah, right. He should be looking at his blindingly bright future – through pitch black shades – and celebrating. He should not be hiding in his study tipping back Scotch. One-shot, after 2.05: When the Bough Breaks.

'Her body still hums with a kinetic energy, an electricity that begs to surge, be released, but this case has her dignity at stake, thanks to the man peeking over her shoulder between calming breaths.

A storm rolls in that night. Post Knockdown.

A two-part exploration into what could have happened if Cuffed took place after The Limey. An M-rated two-shot. COMPLETE

"Still, she's smiling, and it's the same gorgeous, open smile that he's seen more in the past several weeks than in their first few years of working together, stunning in its sincerity. If he didn't know better, he'd think it held an unspoken dream, curved around honesty and love and forever." Castle and Kate attend Ryan's wedding just as their own relationship is falling apart.

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.

For Castlefanfic Monday. Castle, Beckett, and a late night phone call.

She doesn't skip straight to the page, she forces herself to make an evening of it, let the sinful truth of what she's about to do, what she's contemplating, build within her with every preemptive action. She runs the water, hot, steamy. Set during 2x04.

After drinks with Detective Inspector Colin Hunt, Kate Beckett returns home to empty sheets. Post-THE LIMEY. ONE-SHOT. Rated M.

The door is open, just a crack. He listens for a moment, unsure if she's in there or left the light on for him to find his way in the darkened, unfamiliar apartment. Nothing. Pushing it open cautiously, ever-so slowly, he stops cold at what he sees. / Episode insert for 2x17 (Tick, Tick, Tick...).

'Maybe this night can be salvaged after all.' Episode insert for 7x12, 'Private Eye, Caramba'

She wore her hair loose and her jeans tight. A belted leather trench and a matching pair of gloves completed the ensemble. There was no hint as to what lay beneath the coat, which struck him as a little odd. More than a little odd. The lack of a buttoned up collar or a turtleneck was definitely… odd.

Her eyes search his at the door. Pupils rapid, darting back and forth, manic with something he's seen flares of before but hasn't dared put a name to. Post Cops and Robbers.

A series of somewhat related ficlets that follow the adventures of Kate and Castle as they work their way through the book, "100 Sex Positions of the Kama Sutra." Expect the unexpected!

"She focuses on the sounds of the storm, let's them flood through her system as she chants to herself, 'It was just a dream'. But this time it's not enough. She lurches forward and grabs her phone pressing his name before she can change her mind." A post ep. 'what if' for Cops & Robbers (4X07).

'He hadn't come expecting to find anyone interesting, he never does when he ends up in one of these clubs, but the requirement of masks, the promise of unknown identities and costumed anonymity for a night had appealed to him.' An AU meeting on Halloween night. Entry for the #CastleHalloweenBash.

'She hadn't meant to hear. And she most definitely hadn't meant to feel her stomach flip, with something like elation, something like hope, and something too much like relief.' Post 3x12, Poof! You're Dead. For Laura. COMPLETE.

He's not going without a fight. She's not, either. / Episode insert for 2x05 (When the Bough Breaks).

This can't be real. He must be dreaming. This can't possibly be real... Castle catches Beckett in a compromising situation. (Allow me to clarify: This is NOT a sequel. This is the complete piece in one post.)

Episode insert for 4x20, 'The Limey' because of that gorgeous black dress and a forlorn-looking Beckett wearing it, and that desperate, desolate longing in Castle's eyes.

Post-ep for 1x07, Home Is Where The Heart Stops. For my darling Amy. "He leans against the counter, and his eyes are so warm, so wonderful – the way that he normally looks at her when he thinks she isn't looking. This time she doesn't look away." COMPLETE.

Castle's brilliant idea - "act drunk" - is not cutting it. She makes a mental note never to listen to him again. Ever. About anything. - fill for the winter hiatus kink meme.

He was slipping away and it was her last chance to grasp at the relationship they could have, if only she could stop tripping over her fear. Could she make her feelings clear through one more phone call? This is the final part of the "If I..." trilogy and will make the most sense if you've read "If I Had Stayed" and "If I Could Be There." Starts at the end of "Undead Again" (4x22).

[AU somewhere in S3 post-3x17.] Beckett discovers what Castle is made of: big things and little things and silly things, and maybe a bit of magic too.

It wasn't planned, wasn't a date, but when he'd shown up looking striking in his suit and with his arm empty, she'd gravitated to him like she always did, her whole body orienting toward him as if he was her shining beacon in a dark, starless night. Follows episode 4x11, "Till Death Do Us Part." -COMPLETE-

"If it's so adorable, why won't you sleep with me?" An AU episode insert for 03x11. For Meg, because her tags inspired it.

Set in the middle of 2x18 'Boom'. Because when Ellie says she wants to read smut, I can't quite seem to say no.

What Rick and Kate get up to behind closed doors in nobody's business but theirs. They have a system, and it works for them, oh boy does it ever.

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.

"Kate," he calls softly, his voice so gentle. "Look at me."

Post-ep for S1 "Always Buy Retail." What Castle really, REALLY wants Beckett to do. Now a two-shot!

M-rated chapters of Kiss Me, Castle. FMC means...EXPLETIVE DELETED Me, Castle.

A one shot circa season four, a few weeks after the Ryans' wedding. A birthday present for closingdoors and my first M rated fic. Ellie said: car sex, and I said: okay.

It's only the second time he's seen her legs and he's absolutely certain he wants to see more of them. Season 1.

"She took a deep breath, willing herself to sound like she was in control of her own body. Like it wasn't about to abandon her head and run off in a bookstore-borne fantasy." Set in episode 2x05, during and after the Heat Wave launch party. This came about as I was busy appreciating how incredible both Castle and Beckett looked in that particular scene. M-rated one-shot!

She's shaking, her legs wobbly, fingers clamped around the doorknob as if it's the only thing keeping her upright. Her stomach tightens, with fear, with want, with everything she's so carefully held in check for months, years... What if for 3x22, 'To Love and Die in L.A.'. Happy Birthday, Joy!

Post ep for 5x14 The spark of light at her ear catches his eye and he smiles. Wide and bright and proud and answered by her own lip teasing, soul quivering look of happiness.

Prompt based on the unfinished conversation between Castle & Beckett in the isolation tent during 3x16: 'Setup'. "… I wish that I had someone who would be there for me, and I could be there for him, and we could just dive in to it together," she says wistfully." What might have happened next it they hadn't been interrupted... COMPLETE

One-shot set during Boom! (2x18). "Jordan Shaw is pretty cool, but she's not the woman about whom I was writing tonight."

"Maybe it's the exhaustion, maybe it's the way her heart is racing once again at his proximity, or maybe it's just that his words have always gotten to her, reached her in ways that no one else's can." Three-shot based off of Pandora/Linchpin. Now complete.

Sure, all she had done was open the suite door, to return to where she had left him on the sofa. But there was no doubt in her mind that a step into the hotel living room would have effectively pushed the domino that she had worked so hard to keep upright. Starts during 3x22 "To Love and Die in L.A."

A sequel to "Walls," takes place toward the end of "To Love & Die in L.A." Castle decides to act on what he's feeling, especially after seeing Kate in that pool.

The rain has lessened, she thinks inanely, clinging to the random scraps of reality that she can process as they zip and crisscross through her brain. Much less than the downpour that stranded them here, on the side of some highway in the middle of New Jersey. A season four story, set after 'Cuffed.' One-shot. NOT a Christmas story. :)

AU: Beckett is a uniform on the Vice squad at the 12th, five years before she and Castle actually meet in the show. Based on an idea of Cartographical - chezchuckles and I just liked it so much that we each wrote our own. Variations on the same theme, sort of.

She grins and rolls her eyes but lets him keep a hold on her foot as she turns back to her book. His book. **vague Frozen Heat spoilers** One shot. Complete.

He'll take any excuse to treat her like a goddess.

Kate Beckett has had a rough week and Castle has plans to "take care of her". Just a random, fluffy/smutty one-shot.

With a new bar open in town and his team AWOL Castle takes on a little undercover mission of his own, never dreaming that 'Ace in the Hole' is where he'll find his Midnight Queen.

She likes to dominate. And he is more than happy to let her.

He's pretty sure he convinced the lady with the smoky voice that he knew exactly what he was doing, knew how to give her a good time. A variation on the 'Vice Beckett' theme. For ER, on request.

The silence of the night is her enemy. Set after 2x13, "Sucker Punch."

"Is it okay for me to put my hand under your dress if you're not my girlfriend?" - Episode insert for 2.14 - The Third Man.

"What did you fantasize about, Beckett?" he asked, pressing a sloppy, grateful kiss to her mouth. She bit her lip, suddenly uncertain. "Let me show you," she finally offered, taking his hand.

His name is a sigh on her lips. "Castle." Co-authored with PenguinOfTroy. One-shot. No spoilers past Season Two.

She didn't expect it to be like this. Maybe she should have. Three years. So much time. So much waiting, wanting, aching. Too long for it not to come to this.

Castle and Beckett work out their jealousy issues in a supply closet at the Twelfth. Post The Limey.

"So rather than call me or text me or read one of my books, you decided to drive over at ten minutes 'til midnight in your pajamas?"

I hate to do it, but more angst after 47 Secs and The Limey. I can't help myself. It ends well.

Episode Fix for The Limey, because Kate should never have made that last phonecall, she should have been angry! and gone after her guy demanding an explanation. It's M, folks!

Castle and Beckett go undercover in a club and things get a bit out of hand when they get cornered in the bathroom. A twist on a well loved trope, if you will.

Castle really, really wants to find where Beckett hid his birthday present.

Kate Beckett only has so many pieces.

He had provided the spark, but it was she that would set them aflame.

Just an excuse to get Beckett sweaty. Oneshot. Calling it romance seems like a stretch. It's completely gratuitous Plot? What Plot!

Maybe, it's not just about tearing down those walls herself. Maybe, it's also about letting the right person tear them down with her…

Royal is an animal. And, apparently, so are Castle and Beckett.

This is not something she has ever done before, come home with Castle after a case. Spoilers for 4.07 - Cops & Robbers episode stills.

I feel so used, you didn't even get me naked.

A magician never reveals her secrets...usually.

All's fair in love and sex wars.
