[No Spoilers in reviews please...]

A/N: My first attempt at a simple case fic, a short (seriously, the whole case is done in three chapters and one day!), but fluffy one; the victim and murder scene were a special request! For the position involved at the beginning, visualize The Rocking Horse, chapter 2 in Dana Keylits' "100 Sex Positions of the Kama Sutra".

C*B*C*B*C*B*C*B*C*B*C*B*C

Wow. Beckett worked out, but she hadn't pushed her limits like this in a long time, maybe ever. She tipped her head back, lifting the bottle to her lips and gulped down mouthful after mouthful of water; attempting to fight off the dehydration she knew was beckoning her. She felt positively dirty for a moment, sweat dripping down her back, hair sticking to her forehead; slick with sweat all over.

It was all lies of course, and she knew it; pulling the bottle back from her lips, reattaching the top and tossing it aside. She felt spectacular, leaning in again to kiss her fiancé; she was sitting on his lap, his legs crossed beneath her, hers resting against his hips; his hard length still deep within her. Three times in the last hour he'd brought her to screaming orgasm; with his fingers, then his mouth, and just minutes ago with everything he had. He hadn't come yet though, his self-control was driving her insane; her body still tingling, limbs weak, her mind finally returning when he pulled back from her lips.

"Again?"

Kate laughed, she couldn't help it, again? Her chest and stomach were shaking as the near hysteria broke free; the feeling of her muscles clenching around his penetration of her almost enough to push her over the edge immediately.

"Always!"

Rick's hands took a firm grip of her waist and started rocking her against him, encouraging, guiding until she took over the tempo; shifted from rocking to lifting her self up and down. Her hands drifted to his head where she took a firm grip, to anchor herself while every other part of her was moving against him, rubbing, sliding, creating the most intimate and exquisite friction she could imagine.

Quickly their breathing started to lose its control rhythm, from deep breaths being sought to gasped pants getting away from them. His hands slid momentarily from her waist, just high enough that he could brush his thumbs agains nipples, which drew a whine from her and a pleasured hum from him; then those hands drifted back to her waist, pulling her hips even more firmly into contact with him; ensure that at the end of every stroke was met by her swollen clit was ground firmly against his public bone.

There was a ringing in her ears, over the roaring of rushing blood, their almost synchronous pants; a ringing that sounded so familiar. A quick glance to the side showed a nightmare: the clock read 7:10AM, she'd been on call for 10 minutes and next to the clock her phone was glowing, blinking, reading [Dispatch]. Her brain hadn't quite caught up though, she continued to stare at the phone even as she continued to move against him; him within her physically, but more so enmeshed with her soul. Eventually the screen went blank again and she turned back to face Rick, her eyes search out his, hands still clench in his hair, mouth searching out his again as she poured her love into him.

Her body was tingling, from her fingertips threaded through his hair to her toes tucked into the side of his thighs; what he could do to her with a look was crazy, with a touch insane, with his love? It blew her mind on a daily basis. Sometimes she blew his as a reward; a treat she enjoyed just as much as him.

She had to tell him, communicate how special this was, breathless she pulled her mouth free to mumble agent his, "We have.. No.. Sex life.. You know.."

Rick responded with no more control of his breathing than he had, "Feels like.. We do.."

She shook her head, which did truly interesting things to her hips and the feel of him moving within her, "Love... Life.."

Keeping up the twisting motion her head shake had inspired, she felt him change at her words; body tensing, firm planes of muscle taking on a harder look, hands squeezing her waist even more firmly, pulling her down as she sank on top of him, boosting her as she rose up. Legs starting to give out she heard it first, a groan starting in his belly, up through his chest and exiting his mouth as a low moan even as she felt a hard twitch, a spasm of him within her.

That alone was enough, the final straw for this morning of bliss, her body quivered as her pleasure exploded again, this time in response to his. Her cries were choked off, short of breath to support then; his no more than panted groans rather than fully voiced exclamations. From the burning heat where they joined to sparkles flying across her vision; she felt as if she was seeing fireworks from within, as an exploding and spinning Catherine wheel herself; the entire experience made her dizzy and lightheaded.

Still coming down from their combined highs, they both heard the ringing this time; both glanced over at the phone, as it's screen now flashed [Esposito]. Kate flapped her hand in its direction, but lacked the strength to reach or it, looking quickly at Rick, silently begging him to fetch it for her.

Taking it out of the shaking hand offering it to her she quickly pressed [Accept] and tried her best to answer, while still hopelessly, deliriously out of breath, "Beck.. ett.."

"Woah! Boss you ok?"

"Been.. Working.. Out.."

"Ok then. We got a body. Penthouse of The Four Seasons."

"See.. You.. There.. In.. 45.."

She hung up, no breath for a goodbye. They rested together for perhaps a minute, their bodies still connected, loathe to be separated. Time was not in their favor though, not now at least.

Kate eventually pushed herself back from him, their gazes once again locking as she spoke to her, "You shower. I'll put coffee on."

A weak nod was all she could really manage, "Thanks."

After a quick shower she was drying her hair and starting to put on the morning's make-up as Rick moved past and into the bathroom for his chance to wash their blended sweat away.

Since moving into the loft officially six months earlier her occupation of his space had expanded dramatically, from a draw in the dresser and a portion of the closet space to a major takeover. Her shoes consumed three quarters of the closet floor, her clothing had marginalized his; and now three of the four dresser drawers were hers. Of course one of those was entirely Rick's fault; one was her practical underwear, another lingerie. She had always had a collection before, of more special items; but now the range of options was staggering from La Perla, La Bruna, Sarrieri, and more; colors and style to match every occasion.

It had caused a discussion, not quite a fight, when the wisps of lace and silk had begun appearing only a month after she moved in; she had never wanted to be a kept woman, and she told him so.

Kate had raised her voice as she shook a scrap of sapphire blue lace at him, "I am not some bimbo! I don't need this!"

Rick was holding s hands up in a placating manner, "No you don't need it, but you'll look absolutely gorgeous in it!"

"I'm just a show horse for you? That it? I can buy my own underwear Rick!"

"I know you can, I just wanted to buy something special for you, for me too."

"I'm not a kept woman!"

"You know I don't think of you like that! We're getting married Kate, remember? No pre-nup, this is it for both of us; if anything happens to me you get almost everything. I already changed my will!"

"Nothing better happen to you Rick!"

"Nothing planned Kate, but whats's mine is yours, heart, home, money too. Everything, just embrace it."

"I don't want your money!"

"It's part of who I am, part of it because of you; you want to give it all away? I'm going for share everything I have with you, if you don't want the money we can give it away."

They hadn't of course, she'd just learnt to deal with it; he was generous, it was simply part of him, and she loved all of him.

They had a body, a murder to deal with; which meant a long day, chasing leads, building theory, and usually feeling bedraggled by the end of the day. Such a thought usually drove her straight to the comfortable draw, but today, after the morning she'd had, they'd had; well perhaps a treat and some tormenting was in order. Definitely some tormenting was in order, she finished up her hair still in her comfortable robe and waited for Rick to finish his shower.

As he stepped into the bedroom once again, she made sure he could see and she opened her lingerie draw, dropped her robe, leaving her naked as a babe before his eyes, and pulled out a skimpy La Perla lace thong and bra set; bright red, he so loved her in red. She slipped into the items, smoothing them over her skin when finally in place, she found their texture exhilarating. Rick on the other hand found the appearance and feel of them on her to be a serious challenge to his self control; every-time she wore items from that draw.

His gulp was visible as she smoothed everything into place, "Won't those be uncomfortable? Could be a long day."

Her plan was working already, "For me, perhaps a little, but I don't mind; because for you it's going to make for such a hard day, what I have on under my clothes. You knowing but not being allowed to touch."

"That's.."

"Teasing, it's teasing Rick, you knowing I have on your favorite red thong, that you bought for me, that's now my favorite too; that I have it cupping me between my legs. Think on that Rick. Think on that all day."

He was left staring, mouth open for a moment as she subsequently slipped into long slacks, a white tank and a loose white, untucked blouse over the top.

"Come on Castle! We've got to go!

At the use of his 'Cop' name he came a relative blur of motion, dressed in a sapphire blue shirt, which he knew was her favorite color on him, slacks, and slipping into a pair of loafers.

"I'll grab the coffee."

"Thanks!"

With moments they were out of the loft door and claiming into Beckett's cruiser downstairs, she, of course, in the driving seat.

I was like a ritual they had as he whined, "Why won't you let me drive?"

Beckett shook her head as she backed out of the reserved packing space, "Because it's my car Castle, my cruiser. I always drive my car."

And they were off.

C*B*C*B*C*B*C*B*C*B*C*B*C

Beckett and Castle rolled up to the front doors of The Four Season, seeing Ryan and Esposito ahead of them entering the building; walking in it was apparent the guys had beaten them by enough that they weren't waiting but had already caught an elevator to the top floor.

Riding their own elevator they ensured to stand well apart, no risk tempting fate with police all over the building; not that anything was hidden any more, but still compromising positions would incur unmerciful teasing.

The penthouse suite had a set of double doors opened wide, with uniformed officers stood to either side onto long access; walking past they both caught tier first glance of the sheer sumptuousness that the suite provided. The slow perusal of the room, taking in all the details, including the room service car with a coffee carafe and assorted fruits, was rudely interrupted by exclamations from what appeared to be the master bedroom.

"Woah!" "Holy shit!"

Ryan and Esposito had clearly made it upstairs, and Beckett hurried over towards the sound of their voices, closely followed by Castle. The scene was unexpected to say the least, Lanie leaning over the body of the victim blocking their view, the guys stood to one side mouths agape, and the crime scene unit picking up items of evidence and carefully recording the locations and descriptions.

"Diapers, bib, bottle, pacifier, our victim is into role playing as a naughty baby?" Castle asked as he watched CSU put them in the evidence bag.

"What did I ever do to deserve this?" Ryan sighed, this was not the kind of case he wants to investigate when inspecting a baby, a properly sized baby.

Beckett ignored the peanut gallery to focus on the relevant details, "Lanie? Got a time of death for us?"

"Girl! I have more than a time of death." Lanie stood as she spoke, backing away from the body.

"Vaughn? Eric Vaughn is our victim?" Castle gaped as he recognized the face of the victim that Lanie had just finished inspecting. The sight was really something to grab attention, his arms spread wide, wrists cuffed with pastel blue leather to the headboard, legs sprawled out before him; his only covering a bright white, oversized diaper and a bottle strapped to his head with the latex nipple still between his slack lips.

Beckett's eyes bugged a little, honestly shocked, gasping, "Eric?"

Castle's head prompted swiveled in her direction, "Eric?"

Correcting herself quickly, she spoke again, more firmly. "Vaughn!"

Lanie waited for their little discussion out before jumping in again, "Yes, Eric Vaughn; time of death based on liver temp between 10PM last night and 2AM."

Beckett moved on to the next logical question, "Who found him?"

Ray filled her in, recapping what he'd gotten for the responding uniforms, "Room service, delivery the breakfast; instructions were to let themselves in and leave the cart if there was no answer; we checked, delivery guy was fresh on shift at 6AM, we'll run the background but he's probably clean."

"Dude said he makes a lot of enemies given his job right? I guess someone actually succeeded." Esposito said.

Ryan carried on the theme, trying to build something, the beginning of a case, "Right, angry business partners, and employees we've already seen, could be another; angry husband or boyfriend too maybe. Loads of suspects."

"Yo Castle! You had bone to pick with him too, where were you last night?" He was smiling, but Esposito couldn't resist the dig.

Castle could take a bit of needling in the best of fun, he could push back too, "In bed Espo, with my fiancé, sleeping for some of it. You slept alone again?"

The grunt told the whole story really, matched by the mumbled response, "Whatever."

Beckett, head back in the game now, treating the body like any other victim, as he truly was once she recovered from her immediate shock, acknowledged the time window and moved on again, "Murder weapon?"

Lanie walked around the bed and pointed to a bottle lying on the floor which the others moved to inspect. It was a champagne bottle, bloody on one side, leaving a smear on the carpet where it had rolled slightly.

Ryan bent to take a closer look, before glancing up, "Maybe his guest last night didn't want any of his champagne?"

Espo shook his head, pointing over to the side of the bed, "No way bro, champagne flutes on the side tables; one of them has lipstick. Definitely looks like he had a female guest."

Caste shook his head bewildered, "It really took lipstick for you to think he had a woman up here with him? He'd cuffed to the bed guys, and we all know he likes the ladies."

"Lanie? Can you send the glasses to the lab, maybe we can get some DNA, and see if they can identify the lipstick too, might be useful."

Castle had moved over to the flute, bending to take a closer look before making his thoughts known, "It's Scarlet Orgasm."

Beckett's voice was clearly shocked, his comments were so inappropriate sometimes, "What!?"

He gestured at the flute, trying to direct her glare away from him, and to the evidence, "The lipstick on the champagne flute, it's Scarlet Orgasm. I recognize it."

Esposito shared a quick glance with Ryan before throwing his hand up, "How do you recognize it? Seriously? How do you do that bro?"

Castle was talking to Esposito, but his eyes were boring into Beckett's, "I have an eye for red. I have a really excellent eye when it comes to red."

Beckett had to admit it, he most certainly did have an eye for red, and maybe her plan to torment him today was backfiring already.

Neither of them had broken the eye contact as he kept talking to her, only to her, despite the others in the room, "I remember the ads, turned out very popular with ladies of a certain skin tone; the marketing pitch was that it was the color thier lips went at that certain..."

There was a time and a place for this type of verbal fore play and eye sex, this was not it, "Castle!"

Lanie was glancing back and forth between the two as they stared into each others eyes, flicking between them like she was attending her U.S. Open at Flushing Meadow, "Girl? You blushing?"

Beckett broke off her eye contact with Castle to glare at her friend, "Lanie!"

Lanie was having none of it, she just shrugged, "Well you are."

Turning to glare at Castle for getting the wrong ball rolling, Beckett knew trying to restore a professional environment was going to be hard when she could still feel the flush on blood in her cheeks, but she had to try, "Well! I think we've got what we can here for now, I'm heading back to the precinct to set up the board; guys can you grab the security footage for the last 24 hours and meet us back there?"

Both Ryan an Esposito were wearing identical, contrived smiles; contrived in the sense they were struggling only to smile and not break out in enormous grins, "Sure thing boss."
