1x02 Nanny McDead

"Sex?"

"I'll explain how that works later."

His words reverberated in her ear as Kate lounged in her bed, a glass of red wine on her night table and Castle's latest book, the signed Storm novel he'd given her, in her hands. She was already half-way through the book and had barely taken in any of the plot. She couldn't remember anything she'd read on the last page and was completely confused as to what was happening right now.

She knew the reason, of course; it was Castle. That playboy writer who thought he could just waltz into the Twelfth and have everybody at his beck and call.

Obviously he could, with some help from the Mayor, of course. And now she was stuck with him for as ever long as it would take him to finish that book he was writing.

Part of Kate was interested in seeing what he'd written about her-the fan part of her, she guessed. Yet, another part wished that she could just shoot him and get it over with, not have to deal with him anymore.

Still, there was that part that wanted him there as much as he wanted to be there. He was her favorite author, after all, and how many people could say that they hung out with their favorite author or that said author was writing a book inspired by them. Not many, that's for sure. And she didn't even have to pull an Annie Wilkes to get it to happen.

Kate read the same sentence for the thirtieth time and finally gave up; this wasn't worth the headache. She placed the book next to her on the bed and stood, stretching out, before grabbing the glass and downing it. Maybe she'd just go to bed early and try again tomorrow, when her head was clear. She walked languidly into the kitchen, washing the glass and placing it on the drying rack before making her way towards her bedroom once more.

She wasn't even halfway there when there was a knock at her door. Kate groaned and turned towards the door, sighing and praying that it wasn't who she thought it was.

Clearly, the odds were not in her favor tonight. She looked through the peephole only to be met with one incredibly blue eye looking back at her. Kate rolled her eyes and unlocked the door, pulling it open and Castle nearly fell forward and toppled into her.

"What do you want?" she grumbled as he smiled teasingly at her.

"Nice to see you, too, Miss Beckett," he replied, cheekily. "Mind if I come in?"

Kate narrowed her eyes at him and completely blocked the entrance before he could invite himself in. "No," she said, "and it's Detective Beckett, Castle. You shouldn't be forgetting that I do have a gun."

"Of course not," Castle conceded. "How can I forget it when you mention it every time we talk? Now, can I please come in? I have some questions to ask you for my book." Kate lifted one brow at him. "It'll only take ten minutes, I swear. Please, Beckett?" He gave her his puppy dog eyes and a pout and she rolled her eyes, fighting back a smile.

"Fine," she huffed. "You have five minutes and if I don't like the questions, you're out."

"Deal," Castle agreed, "now may I?"

Beckett reluctantly stepped aside and Castle smiled at her as he stepped in, spotting the bottle of wine on the counter. "Ooh," he gasped, "Merlot!"

"Don't even think about it, Castle," Beckett warned, "you don't have enough time for that. Just ask your questions and beat it."

Castle pouted, looking longingly at the wine before shrugging and sitting down on Kate's sofa. Kate sat on the chair adjacent, as far away from him as possible. "Go on," she said, after a moment of silence.

"Oh! Right!" Castle said, chuckling. "Um…when, exactly did your mother die?"

"Get. Out," Beckett growled, standing up, towering above him.

"Come on, Beckett!" Castle all but whined. "I need to know this for Ni-your character's backstory! Please?"

Beckett huffed. "Fine." She took a deep breath. "I was nineteen, right after my first Semester at Stanford."

"Stanford," Castle repeated, impressed, "good school. What was your major?"

"Law."

"See, I was right! I knew you were going to be a lawyer!"

"Whatever, Castle; next question?"

"Okay, what was your dad's reaction?"

"…he drank. Next question."

"What's one guilty pleasure of yours?"

"I'm not answering that."

"Aw, come on, Beckett!"

Beckett sighed. "Old movies. Specifically Hitchcock films."

"Fan of the plot twists?"

"Something like that. Next question; you have two minutes left."

"What were you like as a teenager?"

"Rebellious, of course."

"Explain."

Beckett sighed. "You know, like bad boys, piercings, tattoos…I had a motorcycle. Don't you have a teenage daughter?"

"Alexis rebels in her own unique way. You have a tattoo?"

"Way to get off track, Castle."

"Sorry. Just curious….where is it?"

"You'll never know. Next question; you have less than a minute left."

"Who broke your heart?"

"Castle, I-"

"Come on, Beckett. You don't need to tell me who, really. Just when and how."

Beckett sighed. She hadn't thought about this in years, but she still remembered his name, and the exact date and time he crushed her heart.

"His name was Peter Macintosh, alright? It was my senior year of high school. We went to Prom together and then I found him with my best friend in the bathroom. She wasn't doing anything but he…he was drunk off his ass and couldn't take no for an answer. I dumped him right there and got the guards to call 911."

"And your friend?"

"She was alright. Nothing happened. But she spent the rest of the year and the entire summer trying to apologize to me."

"And you forgave her?"

"There was nothing to forgive." Castle nodded and scribbled down a few notes in his book, before looking up at her.

"You know they're not all like that?" he said. "Men, I mean. There are a few good ones out there."

Kate rolled her eyes, and began walking away. "Yeah? Well, you might need to point them out to me, because I haven't found any. Hey, could you lock the door before you lea-" She turned around, gasping when she found Castle's blue eyes just inches from her own.

"There are great guys everywhere, Beckett; you just need to open your eyes." His own glanced down at her lips before darting back to stare in the hazel-green of hers. Beckett felt him start to lean in.

"Castle," she sighed, "what are you doing?"

"Shh," Castle said, just as his lips brushed hers. Beckett moaned and found herself deepening the kiss, felt his hands come to rest on her hips and pull her towards him. She didn't even try to fight him as she wrapped her arms around his neck, pulling his lips harder against hers, moaning slightly.

When they pulled back for air, Castle's foggy eyes searched hers for any doubt, but found none; just hunger. Suddenly they were kissing again, neither knowing who had started it and neither really caring. Their kisses were desperate and needy and their hands were searching the other's body, moaning as they each came in contact with each other's sex. Kate gasped as Castle's hand boldly cupped her through her pants and she felt her knees shake, falling slightly into him. Castle grinned.

"A little weak in the knees, Beckett?" he chuckled. She growled-Beckett growled-at him.

"Shut up, Castle," she hissed and Castle moaned.

"You sound so hot when you say my name like that," he growled in her ear, grinding his pelvis into hers, making her moan again.

"Shut up and fuck me," Beckett hissed at him. Castle felt like he'd swallowed his tongue.

"Wh-what?" he asked.

"I know you heard me, Castle. You got me all worked up now, so either fuck me or get out so I can do it myself."

Castle's eyes darkened immediately and suddenly Beckett found herself turned around, her arms supporting herself on the counter, Castle's erection grinding into her ass as his hands assaulted her breasts. "You want me to fuck you, Kate?" he asked, his hands sliding under her tank top to tweak her naked breasts. Kate moaned at the sound of her first name coming from his lips; he'd never called her Kate before. "Is that what you want? But, oh, wouldn't it go over your five-minute rule? Maybe I should just go…" He moved to step away but then practically squealed as Kate reached back and grabbed his crotch.

"You leave now and I will shoot you in the back of the head as you walk away, got it?" Beckett threatened.

Castle grinned, leaning forward to whisper in her ear. "Got it," he said, feeling Kate shiver underneath him.

Then he was back to groping her. Without stepping away from her body, Castle divested Kate of her shirt, tweaking her nipples and making her moan as he nibbled on her neck, simultaneously.

"That feel good, Kate?" he grumbled in her ear. "You want more?"

"Yess," Kate moaned, rubbing her ass against her crotch. Castle groaned in response and lowered one hand to hold her hips still as he undid his fly and button with the other. Kate moaned at the loss of his hands on her breasts, but then cried out as Castle's hand reached into the front of her sweatpants, gliding under her underwear and sticking a finger straight up her hooha. "God, Castle!" she cried as he began pumping a finger in and out of her.

"Rick will do just fine, thank you," he responded cheekily. Kate threw him a half-hearted glare over her shoulder, but Castle just grinned and leaned forward to kiss her softly, which completely contradicted the way his finger was fucking her.

Suddenly, thought, it wasn't. Instead, Castle's hands were working on sliding Beckett's pants and underwear down her long, lithe legs. Beckett moaned at the sudden coolness, which was immediately replaced by Castle's now naked crotch, rubbing against her. "Protection," he gasped into her ear.

"I'm on birth control," Beckett murmured back, "and I'm clean. You?"

"As a whistle," Castle responded, before sliding into her. Both of them groaned and sighed, the feeling overwhelming for them both. Castle kissed the back of her neck. "Oh, sweet Jesus, you feel so good," he moaned.

Beckett let out a strained chuckle. "I'd feel even better," she said, "if you would just move."

"Roger that," Castle said, pulling out half-way before pounding back in. Kate gasped, clenching around him. Castle groaned as he did it again. And again. And again.

He set a fast, hard rhythm, neither having the patience to take it slow this time around. Castle hoped that there would be more time for that and Kate was sure of it. He felt too good for this to just be a one-night-stand.

As Kate began to feel herself getting closer to release, she began cursing, egging him on with her words. "Yes, Castle! Yes! Fuck me! Yes, fuck me! Oh God, Castle! Yes! Fuck me! Fuck me!" Her words drove Castle to pound harder into her, his bites on her neck leaving harsh red marks that he knew she'd kill him for, later.

Kate's orgasm took her almost by surprise. Of course she'd known that it was inevitably coming, but she had been unprepared for how intense it would be. She came, clenching around him, milking him, and screaming his name so loud she was sure that even deaf old Mrs. Meyers two floors up would hear her.

Castle followed shortly after, collapsing against her, the jeans around his legs making it hard to keep his balance. They both just stay there, leaning against the counter, catching their breath.

When Castle regained the strength in his legs, he stood and stepped away, nearly falling on his ass as he attempted to pull up his pants. Kate turned to see as he caught himself on the counter, his boxers halfway up his thighs, his dick still hanging out. Kate looked at it, hungrily.

"Where do you think you're going?" she asked.

Castle's eyebrows rose. "Are you talking to me or," he motioned down, "little Ricky?"

"Not exactly what I would call little," Kate said, teasingly, "and what does it matter? Neither of you are going anywhere."

'Little Ricky' twitched and Castle gave her a small lopsided grin. "We're not?" he asked.

Kate shook her head. "I'm not done with you yet," she said, grinning as she stepped out of her sweatpants and grabbed his dick. She began pulling him towards her bedroom, literally by the dick, allowing him some time to shed his clothing. Castle smiled like a happy puppy all the way there.

"Are you going to kill me with sex?" he asked, making Kate roll her eyes and grin back at him.

"Or die trying," she retorted, winking at him.

Castle groaned, throatily, his erection back to full mast.

It was going to be a long night.
