Title: I Just Want You

Pairing: Kate Beckett/Rick Castle

Rating: M

Summary: Castle and Beckett spend their first morning together in bed—without any interruptions. Alternate start to the morning-after scene from 5x01.

Inspiration: Title is taken from Robert Duncan's piano piece of the same name, which was used during the kiss in the season four finale, and a variation of which was used in the opening scene of the season five premiere.

Author's Note: This is my first Castle fanfiction… EVER. So please bear that in mind while you read, and keep it in the back of your mind as you review. I have never, ever written about these two, though I have thought of it before. Seeing their perfect morning after scene thwarted in the beginning of season 5 just pushed me over the edge to write something. I really hope you like this… Go easy on me if it's not too great. I'm just starting out with these two. :) Please enjoy!

Richard Castle woke with a start, propping himself into a sitting position. He immediately started looking around, started looking for her. But she wasn't there. The room was empty. Empty.

He blinked, feeling his spirits plummet. It had a dream. All of it was a dream. He closed it eyes. Of course it was a dream; it had to have been. It was too good to be real.

He opened his eyes, staring at the space she should've occupied, suddenly conflicted. If she wasn't here, then why were the sheets rumpled? Why did the pillow bear the indent of someone's head? He frowned at the other half of the bed, unsure now as to whether or not she had been here after all.

But when he looked up… There she was. He blinked, not quite believing what he was seeing. He wondered if his eyes could lie to him just as easily as he'd suspected his mind of being able to. Undeterred, he stared at her in awe.

She was gorgeous.

Carrying two cups of coffee, wearing one of his button-downs, her hair falling in curly disarray… Kate Beckett was gorgeous.

She smiled when she saw him, and he couldn't help but think that she glowed. Holding up the cups, she murmured, "Made you a coffee."

He couldn't help but grin, remembering his earlier fear. "So it wasn't a dream."

"No." She smiled, sitting down beside him on the bed and handing him a mug. "You definitely… weren't dreaming."

He took the cup, wrapping his hand around it as he informed her, "Uh, you were right. I had no idea."

"So you liked it?" She asked, interested, cradling her own cup.

"Yeah," he nodded.

"Even the part where…"

"Especially that part," he interrupted eagerly. "I loved that."

"Good," she replied. "Me too." She looked down, smiling to herself.

"So," he began a second later, unable to wait any longer, "you're… on board with this, right? It's not some, 'Oh, I quit, my job, I almost died, I'm in crisis' thing, right?"

"Uh…" she stalled, momentarily confused. "No," she answered honestly a second later, "not for me."

"Okay," he replied happily, "me neither."

"Okay," she nodded. "Good."

"Good."

"But, I um…" She licked her lips, leaning closer to him just by degrees. "I did just quit my job," she pointed out. Her left hand drifted to his shirt that she was wearing, and she unbuttoned it one by one as she leaned even further towards him. "And… I do have the day off." With each word that left her mouth, and every second that passed, she was only getting sexier to him.

"I… I do… too," he murmured, his eyes drifting down to her chest as he stuttered through a reply. His voice trailed off when he could see the smooth curve of her breasts exposed underneath the shirt. God, she had beautiful breasts. He couldn't wait to feel them pressed up against him again, couldn't wait see them bouncing up and down as she rode him.

"Oh," she smiled, "really?"

"Yes," he replied matter-of-factly, reaching forward to brush the shirt off of her shoulder. "So what would you, um, like to do today?"

"Um, I don't know," she mused, shrugging out of the rest of the garment. "We could read."

"We could watch TV," he suggested.

"Yeah," she agreed softly, leaning closer. "We could get something to eat," she offered, moving nearer to him.

"We could do that, yeah," he murmured, bending forward to meet her mouth with his. He could feel her smile behind the kiss when their lips touched. He loved seeing her smile, but he loved feeling it even more. He never thought something as simple as feeling her lips curve upward in happiness could make him feel what it did. He reached up, burrowing a hand in her hair, and she shifted even closer towards him. She wrapped an arm around his back, using his shoulder as leverage to straddle him. His other hand moved to the small of her back, cupping it and tugging her to him. He could feel the heat of her as she rested above his thighs.

Slowly, she brought her legs out from under her and moved them to wrap around his waist. She squeezed him tight with her legs when one of his hands cupped her aching breast. She broke their kiss, whispering his name, "Rick," like it was a curse as his fingers teased her nipple. He smiled, opening his eyes as he continued thumbing her hardened nipple.

"Feel good?" He smiled. His hand that had been cupping her back had fallen to her ass. It trailed over her curves there, rubbing her smooth skin and grinning as she inched her body closer to his. He knew she wanted more.

She glanced up at him with those wicked eyes. "I can think of a couple ways to make it even better," she suggested.

He was about to reply, about to make a snarky comment, but before he could, her hands were on him. He didn't know when her fingers had stopped gripping his back, but suddenly they were fisting his cock, and it took all of his willpower not to come apart just from her touch alone. She had unbelievable hands, and she knew exactly what to do with them.

"Kate…" Her name escaped his mouth in a growl; his teeth were clenched as he focused on holding himself together. He remembered how she'd sounded like she was swearing when she'd said his name earlier. He supposed they complemented each other in that instance…

And hopefully in every other instance, too.

"Does that feel good?" She teased, running her thumb over his tip, smirking when she heard him grunt. "I'll take that for a 'yes,'" she murmured softly, stroking him more quickly now, making him harder and harder.

Finally, he couldn't take it anymore. He wanted to say her name, wanted to tell her to stop, wanted to pull her hands from his… But he didn't want to let go of her delicious torture, either. It was a conundrum, but Richard Castle was good at figuring his way out of these sorts of situations. He was good at outsmarting conundrums. He opened his eyes, grinning like drug addict taking his first hit after quitting as he looked over at her.

Without a word, he reached forward, taking her shoulders in his hands and flipping her over onto her back. He could hear a startled gasp escape her when her back hit the mattress, but he didn't waste time waiting around to see what she would say. His lips went straight for hers, and she moaned aloud when their mouths fused together. She reached up to thread her fingers through his hair, delighting in the demanding driving force behind his mouth.

One of his hands trailed up the length of her leg—first up her calf, then around her knee, along her inner thigh—as he situated himself above her. His fingers were just beginning to tease her wetness when she broke their lips apart, gasping, "Castle!"

He smiled, catching sight of her swollen lips beneath him as he probed her entrance with a solitary finger. "You tease me, I get to tease you. Tit for tat."

Her lips split into an amused smirk. "You're gonna need more than one finger to tease me properly, Rick."

His eyes sparkled. "Oh, is that a challenge I hear in your voice, Detective Beckett?"

She grinned. Her hand ran down his chest before falling even lower to curl around his cock. She knew that he was more than up for any challenge she could throw at him. He was a grown-up boy scout: Always prepared. "What do you think?" She taunted.

"I think," he murmured, now pumping a couple fingers inside her as he bent more fully over her, "that you're asking for it."

She laughed, throwing her head back. Her laughter was short-lived, though, for she was already breathless from his tireless fingers. "Whatever—gave you that idea?" She wanted to know.

"Hm," he smirked, slowing his fingers inside her just as her inner walls were crying out for more. "I don't know…"

She bit her lip so she wouldn't whimper when his fingers left her. But god, did she want them back. Her eyes immediately fell to his cock, hoping he'd take this opportunity to fill her, stretch her, just as he had last night. Her body was throbbing for him, even after all that had gone on between them last night. She couldn't remember the last time she'd had so much sex in such a small window of time.

She smiled to herself. Who was she kidding? This was Rick Castle. Of course once wouldn't be enough. Not for either of them.

Though she'd told herself not to whimper before, it was impossible to hold back that strangled moan of desire when he brought his soaked fingers to his mouth. She felt like she could come just from watching him suck her own juices off his fingers. She stared at him, mesmerized and more turned on than she'd ever been with anyone else.

He caught her looking—of course—and smirked, pulling his fingers from his mouth with an audible pop! He bent forward, close enough so that their breath mingled in short, heated exchanges. He bumped his nose against hers, nuzzling her as he wondered seductively, "Do you want a taste?"

Kate felt her tongue roll up into a knot. She opened her mouth, parted her lips, but she had no words. He took it as an invitation anyway and covered her mouth with his. She couldn't help but moan when his tongue entered her mouth, and she smiled to herself as they moved together. She tasted good, even to herself.

"Mm," she purred when their lips eventually parted. She bit down on her lower lip seductively. "Now I know why you spent all that time between my legs last night."

Rick smirked at her, adjusting his position above her. She clenched her thighs together, desperate for some of his hot friction, desperate to have his thickness inside her. She parted her legs a moment later, signaling that she was open and ready for all that he wanted to give her. He smiled, running his hands over her smooth, tanned thighs. She separated them even further as his hands inched closer to her wet, hot center.

His eyes found hers, and she could see the question there. He didn't even have to voice it, and neither did she have to answer aloud. She simply reached forward and gripped his shoulders, and then nodded. She clutched him tight, knowing she'd need something to hold onto in just a few minutes' time.

Her eyes closed and her body bowed up to his as he slid himself inside her for the first time that morning. It had only been a few hours, but god, already it felt like it'd been four years again. It felt like this was the first time, even still. In reality, it had to be at least their fourth. At least.

Kate Beckett smiled, her eyes closed in serene bliss as he began thrusting himself inside her. She didn't know how he did it—maybe it was all the practice he'd had over the years—but he seemed to know on instinct exactly how she liked things. Perhaps—and the more she thought about this, the more she thought it was the likely option—it was because he knew her so well. After four years of working together, he knew nearly everything about her. He knew how her mood would swing from one thing to the other; he knew when to leave her alone and when to run to her side.

Above all, though, as she'd learned over the past few hours, he knew exactly how to make love to her.

She could still hear his voice in her ear, still hear the screams, the bullet leaving the gun, and the blood rushing through her body. Kate, I love you. I love you, Kate. She had stared up at him in awe at the time. She was speechless. She'd been shot, yes, but this… Him confessing his love for her… That was at the bottom, the complete bottom, of expectations she'd had for what would happen during Captain Montgomery's funeral. It was even below getting shot in the heart.

"Kate…" He murmured now, trailing his lips from hers, over her cheek, down her neck.

She blinked her eyes open, and clutched him closer with all her limbs. "Rick…" Her arms wrapped around his broad back, her legs crossed themselves behind his waist. Her body shifted forward which each thrust he gave her. He was steady and sure this morning, completely in his element—an interesting place for him to be, all things considered. But that's where he was.

Kate ran her fingers through his hair, clutching at strands at random as his tempo began to increase. She knew it would be over soon. They were both hungry this morning, hungry for each other and hungry for release—even after how satisfied they'd been when they'd finally passed out the night before. She was only now beginning to realize that it might be a long while before they were ever full of each other.

Her breathing was growing shorter. She could feel sweat bead on her skin. She wondered who was saying his name until she realized she was chanting it incessantly, keeping time with his thrusts by gasping his name. "Rick, Rick, Rick…"

He, conversely, kept quiet. That made her smile when she was able to remember how to use any muscles except the ones that were directly connected to him. He'd been so vocal last night. She'd hadn't exactly pegged him for such…Then again, she hadn't pegged him for much. All she knew was that he'd had extensive experience in bed with all sorts of women; so the most she knew at the start was that he'd be good. That assumption, of course, was correct.

But how wouldn't he be good? Writers don't get dates with supermodels because of the brilliance of their printed word, regardless of their fame in the publishing industry.

"Rick…" She could feel her orgasm coming on now. It was just a few strokes more. It was so close. She was so close. She needed her release. "Rick, please…"

"Hm." He grunted unintelligibly in reply. "Gimme a sec," he muttered tersely. He was breathless, too. She would smile upon realizing that she made him that way if she weren't so tightly wound already.

"Rick…," she moaned, drawing out his name in a one-word plea.

"Just—wait," he grunted out, pushing into her with a deeper, harder thrusts this time. She couldn't help but squeeze him tight with her inner muscles, increasing their joint pleasure. He hissed as she did so, and she grinned for a split second before he pushed inside her again.

"What—am I—waiting for?" She demanded to know, using her legs to pull him closer and closer. Her nails dug into the skin of his back. Neither cared that she was probably drawing blood.

"I want to… come with you, Kate."

"I'm so close," she whispered. Her brown eyes found his, obviously worried they wouldn't have enough time.

"I know," he replied shortly. She could feel the sweat on his body underneath her hands.

"Rick," she whispered when she knew she was only seconds away, if that. "Hurry…"

She cried out a moment later, after a particularly deep thrust of his inside her. She fell apart with a hoarse shout—have nearly lost her voice the night before—and he spewed an array of curse words as he went with her.

He managed to prop himself up with his forearms as he released inside her so he wouldn't crush her, but eventually his arms gave out, and he collapsed above her. He could hear her laugh—bright and happy—emanating from somewhere beneath him.

"S—Sorry," he muttered after he righted himself and rolled off of her.

"It's okay," she smiled, turning on her side to look at him. Her eyes met his—and the warmth in both their gazes nearly melted the other. It didn't help that they both felt so boneless, so drained. The two felt completely, deliciously weightless.

"What… now?" She wondered a couple seconds later, still a bit breathless, but wanting to know the next step.

"Wanna watch TV?" He suggested, glancing over to her with a grin. "I think we can still catch the end of the news we missed earlier."

She laughed, bending sideways to lay her head against his shoulder.

"Kidding," he added a moment later, drawing her body up against his with an arm wrapped around her back. One of his hands reached for hers, and he placed his hand on top of hers, rubbing his thumb over the back of her palm. "We can do whatever you want to do today, Kate," he murmured into her hair.

Kate Beckett smiled to herself, pressing her head more firmly against his shoulder and snuggling her body into his. She turned her hand over so that they could thread their fingers together. "I want to stay here," she murmured, resting her entire body against his.

Even though she couldn't see him, she knew her request made him smile. "Then let's stay here."

The sun streamed in, warming the room and warming their naked bodies, but Kate Beckett and Richard Castle shut their eyes to the intrusion of normalcy. Neither wanted this day to be just like any other day. And it wasn't.

Detective Kate Beckett was lying in his arms, lying in his bed, and telling him she didn't want to leave. Richard Castle had spent years trying to get to this point. He'd spent years believing it was a useless quest, believing she'd never want him, never accept him, never see him the way he saw her. But she did.

"Maybe we can go out for a late lunch later," she mumbled tiredly, stifling a yawn against his chest.

Rick felt a smile tug up his lips, and he tilted his chin to press a kiss to her head in silent thanks. "You wanna go out?" He murmured into her hair, only half-teasingly. The other half of him was dead serious. He hadn't even thought about what would happen when they left this room. How would they act? What would they do? What were they now?

"Yeah," she murmured. She squeezed his fingers faintly, exerting just a light pressure. "I was thinking we'd go somewhere on Eighth Avenue. 'S nearby, right?"

"We can go wherever you like," Rick replied quietly. He hoped she couldn't hear how quickly his heart was beating. With one simple request of hers, they'd gone from a one-night hook-up to a lunch date. In public. He'd never even thought about the fact that she might want to hide their relationship, but now he felt like he'd dodged the biggest bullet in the arsenal with just a few words.

"Is it okay if I sleep for a bit?" She murmured. Her head shifted just a fraction, tilting back to look him in the eye. There was a sleepy smile on her face, but mischief in her eyes. "I'm… tired."

He grinned, bending down to kiss her on the lips. "Sleep as long as you need to."

She smiled gratefully, reaching up to cup his cheek and keep his lips close. "Are you sure you don't have anything to do today?" Her thumb skimmed over the skin of his cheek gently.

Rick bit his tongue so he wouldn't reply, Just you. "I'm all yours," he answered instead, a carefree smile on his face even though he'd meant every word.

Something was different about her face when she whispered back, "I'm all yours, too," before resting her head on his chest again. A few minutes later, he realized what was different. The sleep had left her eyes. But there was something else—something warm and deep hiding within them.

He wouldn't press her now; he'd vowed that to himself and her silently last night. But one day… When things were more serious, when their relationship had a solid foundation…

He'd ask her if she loved him.

He knew he loved her—that was a fact; it wasn't going away and it wasn't changing—but Kate… She was a different story. And he didn't want to chance it now, not so early, not while things were still unsteady…

He remembered that look in her eyes as he settled back against the pillows and closed his own eyes. Just as he was beginning to slip into unconsciousness, he realized what he'd overlooked. He realized he already had his answer.

That look in her eyes as she'd stared up at him, sleepy and tired but so joyously happy… was love.
