Disclaimer: Nope. Still don't own Castle.

[No Spoilers in reviews please...]

A/N: Yes I did. I wrote a second chapter. Blame Flashpoint33 for this one, really, go ahead; one typo and a delayed chapter 18 (which is now up!), and this is the result! Yes it is still utterly absurd! Read all the warnings in Chapter 1 FIRST! Still here? Proceed at your own risk.

It wasn't until the elevator doors closed behind Castle that Beckett unfroze, realizing the words she had called out to him had not prevented his exit, "Shit!"

Vaughn lifted his head from her neck as she pushed him away from her body, leaving her a little more room to catch her breath. She was flushed, warm, hot even; heart beating a mile a minute now and not because of the lips that had just left her neck.

He was looking at her, a certain pent up tension she could see, eager to step back into her space at the first sign of acceptance, "What's the problem Agent?"

"That was my fiancé!"

"I think was is the operative word there. Was your fiancé."

"Fuck you!"

"Anytime Kate! For a repeat performance like that? Anytime!"

Her frustration was back now, falling on her with full force; she let out a shrill, primal scream, "Argh!"

"That sound is one I want to hear again! You really were exquisite you know. Amazing! We could head right back in if you like; I'd like you on top this time though, leaves me a better view."

"How am I going to... Wait? You knew I was engaged?"

"Of course I knew Kate, I've been keeping my eye on you."

"You've been watching me?"

"More observing, I like to keep track of attractive opportunities."

"I was an opportunity?"

"More your fiancé being out on the book tour, that was an opportunity."

"You knew I was in a relationship and you called me anyway?"

"Of course! You didn't have to come now did you? At least not until I got my mouth between your legs, then you couldn't stop yourself could you?"

Kate couldn't help but repeat herself, not a question anymore; she'd thought she was the one using him, "You knew that I was engaged."

"It's hardly a secret now is it? Plus, you are wearing the ring. I think you pulled some of my hair out when it got tangled up. You really were pulling it hard during..."

"Shut up!"

"Well I don't see the problem, it's obviously not a serious engagement..."

"Of course it's serious you ass!"

"You have an interesting definition of serious then! Well, you did say you were serious the last time too; before we were interrupted by the sniper."

"Interrupted? I pushed you off you jerk!"

"Well, nudged maybe. You didn't nudge this time though! Plenty of pushing and pulling this time Kate."

"I need to find him! To explain!"

Vaughn tilted his head while looking at her, and utterly bewildered expression forming on his face, "I really don't think you need to explain much; I really think he got the message."

Beckett pushed passed him then, storming off down the corridor; then turned to face him, red thong in hand as she gesticulated, "These aren't even mine!"

The smirk that spread across his face then was simply repulsive to her, "Keep them anyway, plenty more where they came from."

Beckett rushed towards the elevator, fixing her clothes on the ride down to the lobby; she hopped a cab to the Georgetown home she shared with Rick when their schedules allowed. The home was empty, cold, dark.

Beckett knew where he'd be headed: the loft; she had to go to him, inform the office first, arrange a flight, pack for a short trip. She needed to talk, to explain; not for a moment did she doubt her future, he'd forgive her anything.

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

As soon as she came through the door he was on her, pushing her up again it with a bang; forcing her to drop the bag which he then kicked away from them. He'd never forgive her for cheating on him; but he needed her now, knew she had only just arrived in the city, come straight to the loft. Angry sex was the best salve; controlling this as revenge against the memories of what he had seen, the ones of her and him burnt into his minds eye. Angry, revenge sex, that was what he needed; and he was going to take it.

Rick started pulling her clothes off, leaving them strewn across the floor by the doorway; soon leaving her in nothing but bra and panties. Panties. He could feel himself almost shaking with anger as he looked at the panties; reaching down to tear them at the sides, throwing them away as so many things had been thrown away that day. Her turned her around, leaning his weight into her back, pressing her up against the door; quickly divesting her of her last item of lingerie.

He slipped both hands between her and the door, one shifting up to squeeze her breast, the other down between her legs to cup her there. Rick wasn't gentle, pinching at her nipple; pushing two fingers inside her while she was merely damp, feeling the friction as she whined lightly in protest. Leaving his fingers buried inside of her he pressed his thumb firmly into her clit, circling it, drawing a little moisture from her to lubricate its path. Soon enough he could feel her supplying what he needed, liquid need oozing from within her; her body's cry for more. Rick obliged, moving his fingers in rhythm to his pinching and twisting motions on her breast, in sync with his swirling thumb.

Rick knew he needed this, the feeling of control, to take back his life; so many things had slipped away that just this temporary affirmation that he actually could have what he wanted was repairing a hole in his soul. Her arms reached up, over her shoulders, resulting in him pushing her even more firmly into the door even as her hips jerked and twitched in time with his hand. She grabbed at his hair, pulled him to her neck as she tilted her head to the side; drawing his lips to the place on her that he knew drove her crazy.

As he ran his teeth over the skin of her neck, where it joined her shoulder, he felt the motions of her hips stutter; no longer twitching in time with his motions, but simply jittering against his hand. Her breath had turned into panting moans, growing more and more pronounced as her motions became more irregular.

Rick had no intention of stopping, slowing; no intention of teasing here, he wanted to break her, crack her wide open on the edge of his fingers and mouth. He widened the territory his lips roamed, seeking the perfect spot; and found it, where he could feel her pulse under the tip of his tongue, between his teeth; he bit down hard, and felt her unwind, letting out a cry between heaving attempts to draw oxygen into her lungs. He slipped his hand from within her, no gentle let down for her, this moment was over; moved it it up to grasp her other breast and massaged her own slickness into her nipple.

As her breathing turned from pants to simply deep breaths, body shaking to simply quivering, he grinned against her neck, marks clearly visible on her shoulder; pleased with himself, for taking the first bite of what he needed.

She pushed herself back from the door, spinning in arms and placing her hands against his chest. Rick felt her push, driving him backward across the loft; her eyes flashed fire, burning with desire, though he could not tell if it was truly for him, or whatever man happened to be convenient and could meet her needs. Right now he didn't care, he was using her too; they'd never have a future together anyway.

He was driven quickly into his office, to his desk where she started haphazardly pulling off his clothes, ripping his shirt apart before discarding its remnants; pulling his pants and boxers down in one motion before pushing him down into his desk chair.

He couldn't help but smile, didn't want to, but couldn't help it as she dropped to her knees between his knees and pushed them apart. She spoke then, for the first time, "Hmmm. Tasty." Diving in like it was a feast she'd been missing her whole life.

His hands gripped he arms of his chair, knuckles turning white as she sucked hard at his head; no gentle teasing for her either, just a need to be fulfilled. Her tongue began to sweep across his sensitive tip, hooking and curling, poking into him; seeking out his essence with the knowledge that she was pushing him where she wanted so badly to take him. Her motions became more vigorous, a rapid bobbing added to every other sensation that assaulted him.

Rick could feel his abdomen start to tighten, his climax approach; her control of him reaching a near crescendo. He needed the control though, no matter how good, even great if felt to have her lips and tongue wrapped around him, he couldn't give up the control of this evening to her. Pulling her head away from him by the hair he used to love feeling brush against him, he was met by a momentarily confused look until he spoke, "On the desk."

The promptness of her response was staggering as she leapt to her feet, perched herself on the edge of the desk and leant back on her elbows; her eyes bore into his as she wantonly spread her legs, ankles placed on the arms of his chair as he shifted it forward.

The smell of her permeated his nostrils as her moved quickly towards his glistening target. He took a bruising grip on her thighs, determined to control the motions he knew he could draw from her; he dove in, drank at the font of her, licking from the entrance of her to her tight, erect bundle of sensitive nerves. His range was broad at first, exploratory; before he narrowed his purview to just the most sensitive parts she possessed. Rick grinned into her as he focused, her whole body fighting his grip on her, the immobility he imposed. It didn't take long before he heard her flop back against the desk, arms giving up their support; not long after that before he felt her hands in his hair, threading through, caressing.

When he pushed a finger slowly into her, just to the first joint, her hands became less gentle, caress shifting to grasp as she pulled his mouth tighter against her core. Rick had succeeded in stealing her self control; the knowledge drove him forwards, two fingers, nips and bites in addition to concentrated strokes from his tongue. Soon he had won another victory as she cried out, and gushed into his mouth.

As she recovered from her high, chest still heaving, he hauled her up off his desk onto her shaky legs. Spinning them around her pushed her backward this time, firmly, quickly; forcing quick unbalanced steps as he maneuvered them both into his bedroom and toward the bright white, freshly made bed. At the last moment he firmly grabbed her by the waist, lifted and threw her down; drawing a laugh from her parted lips and a broad smile to accompany it.

Rick wasted no time, crawling up onto the bed and between her eagerly parted thighs. She was watching him move between her legs, licking her lips; eyes beckoning him forward, hands reaching between them to guide him where they both wanted him. No gentleness, no easing entry for her; he was going to fuck her, just like she'd fucked over their relationship when she cheated on him.

He pushed her hands away, aligned himself to her and pushed completely within her in a single hard thrust; not waiting for her to adjust he repeated it, pulled almost all the way out and pounded back in. She was tight, but so wet, so soaked that his vigorous motions apparently were exactly what she sought if the immediate moans and gasps spilling from her parted lips were any indication. A wicked smile crossed her face a she firmly grabbed and twisted her own nipple, moving her other hand between them; he watched as she began a rapid circling motion on her clit, never slowing his own metronomic rhythm, in, out, as she pressed and circled, in, out, as she pulled and twisted.

She was writhing before him as he held her hips and accelerated his rhythm. Light twinkling off the perspiration on her flushed chest, even as his thrusts drove her shoulders deep into the bed covers; her hair flying as she thrashed her head side to side. Deep in her, flying hair, twinkling light; she came, again, her whole body went rigid, quivered. No scream broke free, instead a purr; even as he growled and found his own release, jerking her hips even tighter against his.

He heard a familiar but so, so angry voice call out from behind him then, "What the fuck is going on?"
