A/N: So, I couldn't resist. Had to take my story 'Lazy' and make it part of my idea for analphabet of Caskett. This chapter is my first attempt at angry Rick & Kate so not sure if it actually translated well from brain to page. Let me know! And be warned, I dropped about a hundred F-bombs.

Chapter 2 – Angry & Angsty

"Castle, if you know what's good for you, you'll go home. Now!"

They are at her apartment; he'd found her there, eventually, after she stormed out of the loft in the middle of an argument. She's still absolutely fuming; angry at him, but if she's being honest, angrier at herself. She's sweaty, red-faced and panting because for the best part of an hour she's been punching the crap out of the floor-standing bag she uses for boxing workouts.

"If I know what's good for me? You're good for me Kate," Castle says in a low voice, his tone deceptively calm.

"Are you sure about that?" she says as she roughly drags her gloves off each hand.

"For fuck sake Kate. How many times do we have to dance in this circle? You are good for me and if you'd just spend a little less time inside that brilliant, analytical mind of yours you wouldn't keep over-thinking and over-complicating this and you'd remember we're good for each other."

Castle's jaw and fists are clenched tight, he's frustrated, angry and he wouldn't mind having a turn punching the hell out of something. Earlier that morning he had broached the subject of her moving in and it sent her into a tailspin. Neither of them is sure why, because she's practically living there anyway, plus things between them are actually unbelievably good. Maybe that's the problem; everything is going too well so Kate's waiting for something to ruin it; and her propensity for spending too much time in her own head, even though she wants to live with him and knows it's where they're headed, has her almost convinced she's going to ruin it, ruin them.

They had argued for close to an hour at the loft; their first real voice-raising, profanity-inducing fight and she'd just walked out in the middle of it.

"I need to get out of here before one of us says something we can't take back," she'd said.

"Well that's fucking great Kate. So much for not running."

"Jesus Castle. I'm not running. We both just need to calm down because we could go 'round in circles like this for hours and if you care to remember something else I said when I promised I wouldn't run, I said we shouldn't let the sun set on an argument. Well, this isn't getting us anywhere so I'm ending the argument." And in four angry strides she was out the door.

"How is you walking out now stopping the sun setting on this?" he'd called after her, a little dumbfounded by her logic. But he let her go, because arguing with her was exhausting and they did both need to cool off. When she didn't return or answer her phone after a couple of hours though, he went looking for her - he was worried about her, but still angry and desperate for some sort of resolution.

They both came back to the present then.

"Yeah well, if you wanted un-fucking-complicated Rick, you picked the wrong girl. With me you've got complicated in spades and I can turn dead simple into unbelievably complicated in a heartbeat."

He can't take his eyes off her as she stands there in front of him; shoulders back, chest heaving, eyes blazing and that prominent vein on her forehead, the one that surfaces when she's worked up for any reason, especially just before she comes, is visible under her flushed sweaty skin. He can't help himself; he's irritated, exasperated and incredibly turned on. He doesn't want any other girl, he wants Kate Beckett even though he's certain she will finish him one day... in more ways than one.

"And you can turn angry into sexy in less than a heartbeat - without even trying." Rick blurts. "You don't even know you're doing it do you?"

"Geez Rick. What the hell are you talking about?"

"I'm talking about you," Rick says as he grabs her and pulls her against him. "Miss 'back straight, boobs out, lip-biting, Beckett-glaring, frustrating...' Ughhh! You're all fired up and ready to go toe to toe with me and it's sexy as hell."

"Don't you fucking dare," Kate warns but her breath hitches, her pulse quickens and neither reaction has anything to do with how angry she is because she can feel how aroused he is. "I am not going to have angry, angsty or any other kind of sex with you right now."

"Are you sure about that Beckett? What about fucking it out? Have you decided to just forget that part of our long ago conversation?" Castle asks, only an inch from her face now. He's going for menacing but his tone is more like seduction; warm and intoxicating, like the feel of his breath on her face. "We're better than good for each other Kate, and maybe we both need reminding just how good."

His lips and teeth are at the side of her neck as he says it, with one hand tangled firmly in her hair and the other inside her shirt teasing the underside of one breast.

"No," she says with an almost credible amount of conviction.

"Yes," he breathes and crashes his mouth down on hers, his tongue roughly forcing its way into her mouth. "I don't wanna fight with you, I want to..."

"No," she interrupts and half-heartedly pulls her mouth from his, even less conviction in her voice this time.

"Yes Kate," he breathes as he unhooks her bra and kisses her again.

This time her "No" is a whimper and it's said against his lips just before her tongue joins his in a duel for dominance that they'll both win by the time this is over.

Their kisses are rough and hot and their hands aren't gentle either. Randon articles of clothing are gone in seconds and Castle immediately shoves one thigh between her legs and backs her a half step to her living room wall, right beside her punching bag. He plants frenzied kisses down her neck and across her chest, his stubble and his teeth marking her skin as he goes. She's clutching at him, his hair and his back, and when he slips his hand inside her underwear she moans loudly.

"I hate you right now," she rasps but her hips automatically rock forward to press her centre against his hand. When he suddenly slips two fingers inside her she swears again, partly at the glorious shock of the intrusion but also in frustration at her traitorous body's inability to resist him.

"I hate you too... Katie," Castle says just before he takes one nipple in his mouth. He calls her Katie because he knows it pisses her off when anyone except her Dad calls her that and he yelps when she retaliates by digging her nails into his scalp.

His revenge is to slow the movement of his fingers inside her just as she's beginning to tighten around them and she hisses, "Don't you dare stop." At the same time she closes one hand around him, over his boxers.

"I'm going to have to stop if you want me to replace my hand with…"

"Stop talking Castle," she interrupts again and gasps as the rhythm of his fingers intensifies.

He's working her up again until he knows she's at the point where she'll do just about anything to have him complete his task. His thumb is pressing on her clit now, for the sole purpose of driving her crazy.

"I'll stop talking if you start. Tell me you want this as much as I do."

She looks him in the eye and defiantly shakes her head but the rhythmic rocking of her hips in time with his hand tells him her refusal is all bravado; so he slows his fingers again.

She whimpers and tightens her grip on him, eliciting a hiss from his own lips but he doesn't deviate from his mission. He's determined to have this angry, hot and magnificent woman pleading for him to…

A hand shoving his boxers down his thighs, then two hands stroking him as their owner whispers huskily, "I want this and I want you", interrupts his train of thought and with a silent Oh God, Castle realises she's almost managed to turn the tables. Lust along with frustration at his momentary lapse only heightens the last vestiges of his anger.

He kisses her hard then, as he removes his hand abruptly, shoves her underwear down and presses his almost painful arousal against her, swallowing the deep moan that rumbles from her chest.

Kate presses herself against his hardness because she wants him inside her, now. She rasps out his name as she grabs his ass and pulls him closer.

"What do you want Kate?"

Her temper flares briefly at the realisation that she won't get what she wants unless she tells him and the emotion just adds fuel to the already blazing fire.

"I want you inside me."

"Tell me how," he says in a voice that's more in control than he feels. They are both trembling, partly from residual anger but mostly from mindless desperation.

"Hot and angry and now!"

"Jesus," he breathes as he presses her firmly against the wall, lifts her slightly and plunges into her in one long, sure movement.

"Fuck." Kate hisses and her eyes fly to his, gazes locking as he starts to thrust into her.

She wraps her legs around his waist, clutches at his back and shoulders and gives in to all the sensations and emotions wreaking havoc with her body and her brain; lust, anger, frustration, regret, longing, but overpowering all of it… love.

"How can you think for a second that we're not perfect together, Kate?" Castle says as he continues to thrust powerfully into her, edging them both towards the inevitable finale.

"I'm sorry," she breathes, the apology warm and welcome against his lips. "I just doubt myself sometimes but I don't doubt us, even if my over-thinking makes it seem like I do."

They are both amazed at their ability to form coherent thought and clear sentences in that moment, but the minute he lifts her higher, grips her tighter and thrusts into her harder and faster they are both lost to the intensity of it. Kate cries out as her orgasm crashes over her and the second Castle feels the power of it he sinks his teeth into her shoulder and erratically thrusts his way to his own powerful climax.

For several minutes they are panting, trembling and oblivious to everything but each other, until Kate unhooks her legs from his waist and allows her feet to drop unsteadily to the floor. Castle has one hand still on her ass but has raised the other to gently cup her face, his thumb softly stroking her cheek.

"You okay?" He asks as he lifts his head from her shoulder and meets her eyes.

"I'm good."

"We're good?"

She smiles at him then, a myriad of emotions passing silently between them. "We're perfect. I'm sorry."

"I love you... Katie."

"I love you too but don't press your luck. You'll get me all angry again."

"If we get to do that again then I'm game… Katie, Katie, Katie." Castle teases, then his voice takes on a more serious tone. "I won't bring it up again."

"Living together?"

"Yeah."

"I didn't say never Rick, just not now."

"Well I didn't mean now," he whispers and kisses her softly. "Maybe after we're married?"

"You're just trying to get a rise out of me now," she says knowingly.

"Yeah we'll, we've just firmly established that angry, angsty Kate definitely gets a rise out of me."

Really interested to know if I managed to capture their emotions. It sounded all angry in my head but that doesn't mean it came across that way to you lovely readers. Please let me know because I wasn't feeling confident. I'm all ears to ways I can improve.
