Prompt: When Demming sends a text saying he's breaking up with Beckett she turns up at Castle's loft all pissed and throwing herself at him. She's shocked to find him saying no.

Detective Kate Beckett knocked hard and rapidly at the writer's loft door. Why isn't he answering?! she thought angrily as she kept on knocking, not even giving a second thought as to what the time was. Well, not until he opened with a big yawn and his robe around his body.

"Beckett? What's wrong?" his tired eyes suddenly widened as he took in his late-night visitor.

"He fucking broke up with me!" she growled and walked past her shadow.

Richard Castle, the writer who followed her around to find inspiration to his books, was as confused as ever, immediately questioning 'who' as he turned to find her pacing in front of his couch.

"Tom! God Castle keep up," she complained and he looked towards the stairs.

Castle made one quick decision, he couldn't have her shouting in his living area, especially not with his mother and daughter sleeping upstairs, so he walked towards her and grabbed her arm to lead her into his office and only let go of her to close the door behind them. Once he turned around again she was suddenly so close he yelped in shock.

"Beckett, what are you...?" he questioned but before he could finish his question she'd put her lips onto his.

Shock filled his bones but the sweetness of her lips finally against his had him kissing her back as if he was being hypnotized. It wasn't until their lips parted, and their tongues met, that he could taste the alcohol in her mouth. He immediately pushed her away from him.

"Wha..."

"Castle, I'm not together with Tom anymore, it's okay."

Kate couldn't see why he would push away, she'd already told him she was free again. She was single, he was single, they had all this sexual tension between them and there was no way he could've missed that, so why would he push her away? She was about to kiss him again but before her lips touched his he had put his hands on her shoulders to stop her.

"Beckett... Kate, you're drunk," he concluded, quietly under his breath added "and angry" before he continued, "you don't want this."

"Of course I do! You're the only one who's made me this hot and you've not even done anything!" she groaned, so hot and bothered by only thinking about him touching her.

Castle had to bite his lip and close his eyes to try to keep his position. Both his mind and body was telling him to give in? He had wanted this for so long! If it just had been at a different time, not when she just broke up with another man, not when she was drunk, not when she was as most vulnerable.

"No."

His voice was determined and she felt a big lump rising in her stomach.

"No? You... you don't want me? I thought that was your whole reason for shadowing me," she was shocked, and suddenly she felt like dying.

No one wanted her. Tom had broken up with her, by text, but that she didn't really care about. She had never really wanted him anyway, but Castle not wanting her? That took her hard, because there was nothing more she'd wanted since the day they met. She stumbled backwards, putting distance between her and the man her heart so badly wanted.

"Kate, don't be ridiculous, of course I want you, more than you can ever imagine," he said with full honesty, thinking and hoping she's too drunk to remember his confession when she woke up the next day, "but you don't. You will regret it and you will not let me shadow you anymore so I'm not taking any chances."

Kate shook her head at that, "no I won't, I won't regret it," but she could see there was nothing that was going to change his mind. Sighing she walked, quite wobbly, over to his deck and sat down in the chair, placed her elbows in the desk to be able to hide her face in her hands.

Castle wondered how much she'd had to drink. Because she wasn't exactly slurring her words but the way she walked and the intentions she had come there with had him worrying about her. He had never seen her this way, and it terrified him that she had thrown herself at him in this state. If it had been in any other circumstance he probably wouldn't have had a second thought about it but this wasn't right. How am I supposed to send her home like this? he thought about it. He couldn't. What if she did something reckless?

"Look, you can stay the night, I can go and prepare the guest room if you like," he suggested and she looked up at him, tears evident in her eyes.

"No, I'm fine," she said and he gave her a look.

"You're not. Come on, lets get you to the room," but before he could have her following him she had turned towards his bedroom, and walked right in there without hesitation.

At first he stood frozen in shock but after a few minutes he sprinted off to follow her and when he came into his room he saw she had removed her clothes, put them in a pile on the floor, and crawled under the big comfy cover. He called out her name but realized it was already too late, she'd fallen asleep with her head snuggled into one of his pillows. With a sigh and a roll of his eyes he removed his robe and crawled down on the other side of the bed, far away enough not to touch her, and decided he'd deal with this in the morning.

Kate awoke with a startle, sitting straight up in the bright room which unfortunately resulted in a pounding ache in her head. She looked around, suddenly realizing she was not in her own bed, but she couldn't quite recognize where she was. It wasn't at Tom's, oh, that's right, he'd broken up with her. Looking down at her body she saw she only wore her underwear, what the hell did I do last night? When there was a distant sound of footsteps she quickly covered herself with the cover and got ready to make up a plan despite her bad headache in case whoever was on their way towards her would be someone she didn't know. The distant footsteps came to a halt right before she could see who was behind the bedroom door.

"Bye pumpkin!" the voice was a familiar one, way too familiar one.

Oh, no! Kate couldn't help but widen her eyes at the realization of whose bedroom this was. What did she do the night before? The door silently creaked open and when his head looked inside she felt her heart skip a beating.

"Oh, you're awake," his voice was not much higher than a whisper.

He pushed the door open and walked inside with a tray in his hands. When he approached the bed she could see it had pancakes on a plate along with a cup, the smell of coffee filling her nostrils, and once he had put down the tray on the nightstand she could also see a glass of water with pills beside it. He turned towards his drawers and as he was searching for something she couldn't help but voice the question circling inside her pounding head.

"C-Castle, did we...?" she stumbled across her words, not able to finish the sentence, too embarrassed by having to ask because of her lack of memory.

He turned around almost quickly with big eyes.

"No!" he exclaimed and cleared his throat, "I mean, no, we didn't do anything."

Kate felt her cheeks blossom red with the embarrassment she was feeling. To her relief Castle turned back to his searching and she let go of a deep sigh.

"But-uh, how much do you remember from last night?" he questioned and she felt her body stiffen.

Once he turned around he was holding up a big shirt that she assumed belonged to him.

"Here, I think this will be comfier than the shirt you came in," Castle threw the shirt to her before he turned around to give her privacy.

She immediately pulled it on to be able to sit up without having to worry about him seeing her more naked than she was comfortable with. She brought the cover over her as far as if would go while she sat with her back towards the back of the bed. He turned around when she told him she was done and it didn't take long before he'd moved the tray from the nightstand onto her lap. She didn't meet his eyes until he opened his mouth.

"Thought you would need the pills, and some breakfast," his voice was almost apologizing and she wondered what the hell happened the night before because she was definitely getting scared by his unusual behavior.

"Thanks," she said and he was about to leave the room when her voice stopped him. "Wait, can you tell me what happened? Did I do something... wrong?"

Castle cursed himself, because he wasn't at all sure of what to say. When he glanced back at her in the bed, so much worry in her eyes, he knew he couldn't deny her the truth. Walking back he sat down beside her in the bed, gesturing his hands for her to start eating, once she took the pills and started eating he took a deep breath.

"You came here last night, telling me that Demming broke up with you. I took you into my office to make sure you wouldn't wake up Alexis or mother since you were being quite loud about it. You-uh, you surprised me when I'd closed the door, anyway, I tried to get you to my guest room but you walked right in here instead and fell asleep before I could do anything so I decided to let you stay."

She looked at him, sensing he wasn't telling the whole truth, besides, he left out how she got rid of her clothes.

"Castle, why was I sleeping in only my underwear?" she asked, keeping her eyes on the pancakes she was eating.

The pancakes were really good, she couldn't remember last time she'd gotten pancakes as good as these. When she had finished them she looked at him, requesting with her eyes that he answers her because, no matter how embarrassing, she needed to know.

"You just undressed before I found you in my bed, I didn't see when you did but I suppose you did it by instinct," he said and she nodded.

It sounded possible. When she was at home and feeling too warm she'd sometimes just sleep in her panties, which made her so grateful right now that she at least had the decency to keep her bra as well. She sipped her coffee and was finally feeling her head

"Promise not to shoot me," he suddenly said and she looked at him with horror in her eyes.

"What?" she questioned with a high pitched voice.

"We kinda... well... you kinda..." he stumbled across his words and Kate's eyes only widened in horror. "You kissed me."

She couldn't help but let out a small laugh of relief, the was he had sounded it had feared her she'd done something worse, a lot worse. Castle got shocked and a big irritating feeling inside the pit of his stomach.

"Why are you laughing? I had to push you away to stop you from doing anything more than just kissing!" he was clearly more upset than she thought he'd be. "You have no idea how hard that was!"

Kate startled at his outburst, when she finally looked at him she saw he'd closed his eyes in order to take deep breaths. Upon seeing his eyes clenched shut she suddenly remembered he was doing the exact same thing when he'd held her back and told her a stern 'no' the night before. Oh my god, she'd thrown herself at him.

"I'm sorry," she breathed out on a whisper, not daring to raise her voice any higher. "I... I didn't know... shit."

She put her hands over her face and bit her lip as everything came back to her. How she'd drunken way too much, how she suddenly had felt this need to find the writer and let him know just how much she'd wanted him, how the only reason they shouldn't were out of their way. He sighed beside her and when her eyes once again reached his face she saw him shaking his head.

"Lets just forget it, I knew you'd regret it anyway," his comment had her eyes widening.

Would she really regret it? Well, she did regret throwing herself at him like she had, because now that she remembered it was quite shameful how she'd acted. But, did she regret the fact that she'd wanted him? Wanted him the way she'd wanted him since they met? Since she read that sex scene in his book, practically about them?

"Look Rick," her use of his first name had his eyes on her in a millisecond, "I wouldn't have regretted it. Honestly, the only thing I regret is how I came at you. I should've..." she sighed, "you know me by now Castle, I don't let people in, and confessing that I-that I want you isn't easy."

She did everything in her power not to so much as glance at him, because it truly wasn't easy. Wanting him was not only physical anymore either, and thinking of starting something emotional feared her more than anything had ever done because she had a feeling that with Castle it wouldn't be something short. No, with Castle it would be for the long run. And even though she feared it, she'd already set it in motion thanks to her drunken state the night before when her, now ex-, boyfriend broke up with her.

"You... you do want me?" his voice was so shocked it was a bit higher pitched than what was normal.

"Yes!" she exclaimed as if it was obvious, suddenly so damn tired of lying and holding back.

She took a grip of the tray and managed to put it back onto the nightstand beside her before she turned towards the man she'd wanted so badly for over a year now.

Castle sat like frozen as she did this, because he had a hard time believing her. What did she mean she wanted him? Like he wanted her? Like she had presented the night before? Before he knew what was happening she'd somehow put her leg on the other side of him and put her hands on each of his cheeks to hold him there. Her lips were on his in an electric and rushed kiss, resulting in him loosing his breath. She pulled away almost as quickly as the kiss had started, letting their foreheads still be in contact as she let it all sunk into his confused, dizzy mind. Was she...? It took a couple seconds before the realization hit him. The woman he'd followed around for his books, the woman who he'd slowly fallen for, was straddling him in his bed while kissing him. He felt arousal go down his spine and it certainly didn't help that she was so close he could smell her cherry flavored scent.

"I want you."

It was all she said, all she could say through the crazed feelings circling around her pounding head. There were two specific emotions so dominant in her body right that moment and she wasn't sure of which one would win. The fear wanted her to pull away from him, pick up her clothes and leave, but the, dared she call it, love wanted her to keep kissing him, to take things to the next level because, she could fool herself as much as she wanted but this was something she deep down wanted. To her surprise, and relief, her words had released Castle from his frozen state and it only took seconds after her last word left her mouth before his denied her any more talking. Her right hand travelled into his hair, feeling his soft hair against her fingers sent pleasure down her veins, and her left hand slipped down to his chest, where she could feel his heart beat to the rhythm of her own. She could feel his excitement as she started grinding herself into his body, pushing herself closer to him than she'd ever been before, and she felt her shirt, or well his shirt but on her body, ride up so the only clothing between them were her panties and, of course, his jeans along with the boxers she assumed he had under. There were no way she could've stopped the moan coming out of her mouth when his hands suddenly gripped a hold of her waist under the shirt, their skin finally touching in some way, and he swallowed her moan before letting his lips travel down to suck on her increasing pulse. She gasped at the arousing sweetness shooting down her veins to her abdomen.

"Rick!"

Hearing his name come out of her mouth like that had Castle loosing it, oh how many times hadn't he dreamt of this?! And the way she was fiddling in his hair? Lets just say like this, no woman had ever made him feel the way solely her hands and lips had, it was crazily amazing! His hands were on fire just by being able to feel her naked skin against his fingertips. When she was distracted he knew she wouldn't be able to stop him, so without any indication of his plans he pushed her down onto her back only to place his body on top of hers. His body pushing her into the mattress and to his surprise she didn't complain at all, too caught up with gasping and moaning as his lips found hers again. She was the one to make the first move at undressing him, gripping his jeans to unbutton the belt, the button and slide down the zipper, and he took that as a cue she was definitely on board with their activities. He pulled her shirt up, immediately getting the reaction of her raising her arms so that he could pull it off, and removed her bra, exposing her naked chest to his dark blue eyes.

The second his lips attached to her right breast she couldn't stop the scream of his name coming off her lips. She was squirming under his devours, reaching an orgasm quicker and deeper than she had before. He didn't let her get any amount of rest before his fingers snaked their way into her panties where they worked magic and it didn't take long before she was reaching a second high. Having adrenaline pumping fast in her body she managed to unbutton his shirt to pull it off and to her relief he got rid of his pants and boxers while she released herself of her panties. When he was finally back with his body against hers she let her fingers wander down to start stroking his hard manhood as she leaned up to kiss him again. He followed her body down to keep their lips connected when she laid her head back into the pillows.

Kate gasped when he pushed into her, connecting them, and Castle couldn't stop the groan rising in his throat when he felt how tight and wet she was. There was no doubt as to what he'd made her feel, how it was thanks to him she was so wet, and he couldn't understand how the knowledge of her pleasure gave him equal satisfaction. He let her adjust to his size and didn't move until she groaned out a 'please Castle'. They quickly found a rhythm so familiar it was as if they had done this for years. It felt so surreal and so beautiful and, god, Kate had been right, he'd had no idea.

"Castle," the warning tone had his fingers stop typing and his eyes looked up under his brows in a fear he was, oh so, familiar with. "What the hell is this?" Kate came into his office with a bunch of papers in her hands.

His eyes narrowed in thought as he tried to see what papers she could've possibly found this time. She threw the bunch in front of him on the desk and the second he read the title he understood exactly. What. Papers. She'd. Found. Break up.

"Shit," he breathed out and looked up at her furious eyes. "Uh... I meant to get rid of these... you weren't supposed to find them, where the hell did you find them anyway?" he suddenly turned the suspicion back on her, because he had indeed hidden his written fantasy-dream far down one of his drawers.

Her angry expression suddenly went blank, probably not even thinking about how her accusation could backfire so quickly. She stammered for a couple of seconds before she shook her head.

"Fine, I was snooping," she said in a 'I give up' tone. But before he could even begin to try and mock her she opened her mouth again. "Still doesn't explain why it exists."

He closed his mouth from the tease he was about to let out and looked down at the papers in front of him. He cursed himself for thinking he could keep it, then again, to his defense, he had forgotten it even existed. Until now. Damn.

"I-uh, might... have been... a little..." he couldn't help pause between the words, thinking about how to say it out loud, "jealous. And, I-uh, might... have had dreams... about you... and Demming breaking up. Come on, Kate, it's in the past, do I really need to explain it?" his last sentence was a plea, and she could see his whole face being flushed from getting caught.

"You fantasized about us having sex right after I supposedly broke up with a guy?" she criticized with narrowed eyes.

He suddenly gave her an obvious look. "Are you really surprised?" he countered instead of answering, which had her biting her lip. "Your hotness and my feelings for you didn't really help my mind creating pg-13 rated dreams," he added and that's when her cheeks became at least as flushed as his were.

Castle stood up from his desk, picking up the bunch of paper and flipped towards the last pages. "The second his lips attached to her right breast she couldn't stop the scream of his name coming off her lips..." he read out loud while he walked up to her, he cheeks suddenly blossoming red.

When he was about to continue reading she snatched the papers from him to stop him. "Castle, no, it's time we burn this. Should I know about more of these?" she questioned and he smirked before putting on a frightened expression.

He was shaking his head while saying 'no' but she had of course already seen the smirk and knew he was lying. "Castle," her tone was as warning as he'd ever heard it since they got together a couple months ago.

"Fine, I have more, of course I have more, I had a lot of dreams about you. I still do," he confessed, "but hey! Where's the harm in this? It's not like I'm going to publish them, or share them with anyone else." He shrugged his shoulders and Kate rolled her eyes.

"I don't believe you'd do that on purpose but what if someone finds them? What if your mother or Alexis finds them?" she questioned harsh.

"If they would've found them, they would've found them already," he concluded and she groaned.

"Not the point here."

"You only found it because you were straight out snooping in my drawers, no one else does that."

His voice was a perfect mix of mocking and accusing which naturally left her feeling a bit guilty and a bit embarrassed.

"I'm a detective, that's what I do," she tried to defend herself but he just snorted with a roll of his eyes.

"You need a warrant for that," he was definitely enjoying this way too much.

She smacked the bunch of papers against her leg in frustration as she turned away to walk out of his office. Before she could even take two steps towards his bedroom before he grabbed her arm, pulling her back to him. She landed with her body flushed to his with his arms around her in a determined lock.

"You know, those stories are a lot better than watching porn," he said in a low, husky, voice that had her insides tingle with arousal. "You know, I have one written that takes place in the precinct, at night, when no one's around."

A shiver went down her spine, god why did he have to be so hot?

"There's another one starting at the cinemas, you're wearing a skirt and I can't keep my fingers at bay. And then there's one were we're undercover as a married couple checking into the honeymoon suite, with only one bed we end up making love all night," his voice gets lower, deeper, as he continued counting up scenarios where they'd had sex in his fantasies.

All of a sudden Kate couldn't take it anymore, claiming his lips with hers, not only to shut him up but because he'd wind her up so much there was nothing that could stop her now. Castle didn't mind at all though, this had been his plan all along, well, since she'd said he needed to throw them away. He backed her towards his bedroom and as their naked bodies finally connected he made her scream out her approval of keeping his dirty stories as long as she got to read them. She couldn't wait to read them.

THE END
