A/N: Okay, so right after I post on another story that I'm a prude, this naughty little piece came together so easily I decided to type it up. I held on to it for a while, because I am still prudish. And then I thought I could actually have a plot after the three (or more) straight chapters of nothing but gratuitous sex scenes. So please! Don't read it if you can't take it (or if you're underage).

It's definitely OOC. I apologize in advance, but did I already mention 'gratuitous sex'? Hopefully that will make up for the OOC-ness.

Additional notes: Fake case, based on an idea I made up (Kate had to have a reason to be upset so that Castle would have a reason to be "comforting"). Set sometime in the future, so neither is dating anyone (I don't like the 'cheater' stories, but that's just me. And I didn't want to take the effort to get rid of Josh, whom no one likes anyway). Title is from an 80s song, bet you can't guess which one! ;-) I love the 80s! Hmm… anything else? No? I guess you can go ahead and read the boring part after my fascinating, well thought out author's note. :-D

"I just wanna use your love tonight
I don't wanna lose your love tonight." - The Outfield

Rick knew she'd had a hard day. The case they'd just closed had been physically and emotionally draining. The victim had been the parent of Kate's best friend in college. And then Kate had had to fight a girl she'd considered a sister when the killer decided she didn't want to go to jail. Rick could only guess that Kate's biggest torment right now- aside from participating in the incarceration of a friend- was that even though Kate had considered the woman a sister, she'd had no idea of the torment and abuse her friend had suffered throughout her entire life. So Kate was not only mourning the death of a woman she'd once loved, she was dealing with the pain and hatred that went along with discovering child abuse.

So Castle was there- at her front door- to offer a couple different forms of comfort: chocolate, chocolate ice cream- as well as strawberry and vanilla- vodka and himself. She could talk to him- if she wished- and he would simply listen.

Rick took a deep breath and knocked. It took a long moment before the door opened, and Rick was sure she'd taken the time to look through the peephole- he'd even smiled, assuming she'd check.

The door swung slowly and Kate leaned against the frame. Rick noted her eyes were red and a little puffy, but dry. "What do you-"

Kate broke off when Castle hefted one of the grocery bags he held and pushed it into her arms.

"Castle?" she snapped, turning to glare at him when he pushed past her into her apartment.

He raised the other bag he still held and just said, "These are going to melt unless we freeze them. Or eat them."

Kate left the front door open and approached Castle, holding out the bag. "I can appreciate what you're trying to do for me Castle, but I can assure it, it's not necessary."

Rick didn't even glance at the proffered bag, but informed her, "Necessary or not, I'm here. And you're not getting rid of me."

Both of them were sure Kate could get rid of him if she wanted to, but Rick had accurately guessed that she wouldn't have the energy or the heart to do it. She sighed in defeat, lowering her arm and the bag. "If you're here to annoy me-"

"I'm not," Rick said, cutting her off. "I'm just here. For whatever you want me for."

Kate sighed once more and held up the bag again. Rick took it this time, knowing she'd let him stay. She closed and locked the front door, while Castle headed to the kitchen to hunt down bowls, spoons and martini glasses.

When Kate entered the kitchen, several pints of ice cream, whip cream, vodka and chocolates were spread out over the table.

Rick gestured with his hands, indicating the array, and told her, "Pick your poison."

"What is all this?"

"Comfort food," Castle replied, an unspoken 'duh' in his tone.

Kate snorted a brief, sarcastic laugh. "You really thought any of this would make me feel better? That chocolates and-" Kate grimaced in disgust at the combination- "Vodka would really cheer me up?"

"No," Rick replied lightly, even smiling a little. "Nothing can make you feel better right now. I know that."

"Gee, thanks for the pep talk," she grumbled.

"But. I can try to distract you. Just for a little while. Whatever you want me to do, I'm here. If you want to talk, I'll listen. And if you want me to sit down, shut up and serve the ice cream, I can do that too."

Kate's mouth twitched into an almost smile. "Sit down and shut up then." Kate sat then too and added, "I haven't seen it happen yet. I'm curious to see if you're even capable of sitting silently."

Rick smiled sarcastically at her, but kept his mouth shut- for once. He motioned toward the ice cream and when Kate indicated the flavor she wanted, Rick tore off the top, stuck a spoon right into the desert, and pushed the whole tub toward Kate.

And despite the sadness Castle could see behind her expression, Kate did smile at him.

She dug out a spoonful of chocolate ice cream and said, "Thanks, Castle."

For a long time, the two sat silently, nursing their ice cream- Castle's topped by a generous portion of whip cream.

Eventually, Kate commented, "The silence has to be killing you."

Rick shook his head. "I don't always have to be talking, you know."

"Could have fooled me," Kate teased half-heartedly.

He smiled in acknowledgement of her joke. "I can talk if you want me to. Did you want to talk about something?"

She shook her head. "I am a little surprised that you're not bombarding me with questions, though."

"If I were you," Castle mused. "I wouldn't have anything figured out at this point, so the last thing I'd want is a nosey writer asking tons of questions."

"Smart man," Kate observed, a bit gratefully.

"I have my moments," Castle agreed.

Kate's mouth twitched again into an almost smile, but she didn't reply and the pair lapsed again into silence. Rick stood then, grabbing two glasses from the counter and filling them with ice. Then he covered the ice with straight vodka and set one glass in front of Kate. Rick took his drink back to his chair, and then held it out to her.

Kate stared at the cup for a long moment and Rick could see she was debating whether or not to drink it. But before he could say anything to encourage her, she picked up her glass, tapped the rim to Castle's cup and downed a good quarter of the drink.

The temperature and the burn of the alcohol made Kate's whole body tremble violently.

"I shouldn't drink too much," Kate mused, even as she took another, more sedate sip from the glass. "I've got work in the morning."

"Montgomery gave you the day off," Rick reminded her sternly.

"And what would I do all day? Drink? That sounds healthy," Kate said sarcastically. "At least at work I can be productive."

"You can take a day to deal with what happened to you," Rick insisted.

"I'm fine. I only got a couple of bruises."

"But emotionally-"

Kate cut him off. "I thought you were here to distract me. Not depress me."

"You need to deal with this, Kate."

Her eyes flashed fire and she snapped, "You think I didn't go through all the grief counseling when my mother died? I know the steps of grieving and right now, I just-" she broke off then, frustrated. Her hands pushed through her hair and she shoved the locks back. She stood then and turned to the sink, rinsing off her spoon. Kate then took the still nearly full ice cream tub to the freezer as she said, "I really don't want to talk about it right now, Castle."

"Okay," he quickly agreed, standing also and turning to face her. "I'm sorry. Whatever you do want from me, I'm here."

Kate turned to look up at him and reiterated, "Whatever I want?"

Rick swallowed hard and fought to hide his body's usual response to her nearness.

The scent of her always got to him and now she was looking up at him- he noticed she was shorter without her heels on- with her big eyes red rimmed and her face scrubbed free of makeup. But Rick still thought she was the most beautiful woman he'd ever seen. And she was saying something he'd only ever heard her say in his fantasies. He wondered if she meant what he hoped she meant or if she was totally unaware of the effect her words were having on him.

"Of course," he finally answered.

Kate's gaze lowered to his mouth and her pink tongue peeked out to moisten her lips. "I want you to distract me," she said quietly.

"What?" Castle asked. He took a breath, knowing Kate couldn't possibly mean that the way it had sounded. He cleared his throat before he could say, "Distract you how?"

Kate took one step forward and she was suddenly in his personal space, her body close enough that her robe-covered breasts brushed against his chest. "However you'd like."

He stared, shocked, into her eyes for a long moment, trying to determine if she really wanted what she seemed to be asking of him. What he saw must have encouraged him, because his hand came up to cup the back of her head and his mouth came down on hers. His other hand went to the small of her back and pressed her body against him. Quickly, Kate took over the kiss, tilting her head to get better access to Castle's mouth. Her hands came up to clutch his head, pulling his mouth harder down on her own. It was almost a bruising kiss but it only made them feel more urgency.

Both of his hands swept down her body then to lift her by her rear end. So Kate hopped a little and wrapped her arms and legs around him, rising up over him as he held her, to come down hard on his mouth.

Rick turned to the table, removing one of his hands from her round backside only long enough to sweep some things across the table. He set her down then and pushed her back, leaning over her on the table to continue kissing her.

Rick's hands moved to the belt of Kate's robe and pulled, quickly untying the knot and opening the lapels. He hadn't really thought about it until now, afraid of where his fantasies would take him, but if he had, he'd have assumed Kate was wearing at least a night gown under her robe. But to find out now, that she'd been naked under the dressing gown this whole time had him instantly hard.

Kate slipped her arms from the sleeves of her robe then pulled Castle's t-shirt from his pants and tried removing it. Rick stood long enough to pull the garment over his head, then returned his attention to Kate's mouth. Until he got distracted anyway, by the journey his hands were making up and down her torso.

Rick began kissing his way down her neck to her chest, but apparently he was moving too slow for Kate. Her hands went to his belt and pulled, yanking his body closer to hers. The belt was thrown to the floor and his pants soon followed, Kate using her feet to push his jeans down faster.

Kate used her hand then to guide his arousal into her body and he began to press into her but then he stopped.

"Kate," he gasped, trying to reason though his mind was focused on how hot she felt against the tip him. "Slow down."

"No," she argued, using her legs around his waist to pull him closer. "Take me. Do it."

"Are you sure…"

"Do I look unsure?"

"No, but-"

"Please, Castle. I want this right now. Just distract me, please. I don't want to think tonight, I just want to feel good."

Rick straightened up then, standing in the circle of her legs and staring down at her body. "I think I can do that," he said, his eyes on her rapidly rising and falling breasts.

"Yes," she agreed breathlessly.

Castle grasped her hips then and pressed inside her body. All his many fantasies about Kate failed to live up to the real thing as he stood there for a moment, simply enjoying the feel of her hot, tight body wrapped around him. Looking down at her, displayed before him, he pulled away and then slammed back into her, watching her body arch and writhe. And just to see her arch her back like that again, he pulled out of her as far as he could without leaving her completely, and thrust back home again. Kate's body arched up off the table this time, and Castle's hands were there for her to press into. He palmed her breasts in his excitement, then molded his hands to the perfect round shape of them. He swept his thumbs over the sensitive tips and watched her squirm.

Kate looked up at him and snapped, "Stop playing with me and take me already."

Rick grinned and asked, "Can't I do both?"

"Just make me feel good. I don't care what else you do."

She rolled her eyes at his impish smile. Bracing a knee up on the table beneath her, Rick quickly began moving his hips in and out of her, making her moan rather loudly, even as he leaned over her and took the peak of one breast into his mouth. A hand slid between their bodies and he began playing with her most sensitive spot as he continued stroking his tongue over her breast with the same frantic pace. And all the while, Kate's hips moved with his, meeting each thrust and intensifying the pleasure for both of them.

Rick had to slow this down or he wasn't going to last much longer. His hips slowed, his mouth moved to taste the cords of her neck and Kate whimpered.

"No. Don't stop," she pleaded breathlessly. "Take me, please. Take me."

"I won't last-" he began, but Kate cut him off.

"Me either. I don't want to last, I want-" she gasped when Rick slammed into her again and began thrusting into her at a frantic pace. "To-" Kate tried to finish her sentence, but Rick's fingers were moving on her again and his mouth came crashing down on her own. Her hips moved to meet each frantic thrust, adding to each movement and sensation. Kate tore her mouth away from his to vocalize her pleasure, panting, whimpering or moaning every time he thrust into her. The tension in her body was coiling tighter and tighter and she moved her hips faster, prompting him to pick up the pace.

"So good," she gasped between cries of pleasure. "So… so good!"

Rick groaned in acknowledgment and gasped, "Good." And then he slowed just a little to make the next few thrusts deep instead of just fast.

Kate rocked her body with his motion, allowing him in deeper and harder and loudly cried out her pleasure. Her hands had been clutching his shoulders, but just then she moved to scrape her nails over his flat male nipples and his body jerked in surprise. When she began playing with them, Rick moved to kiss her mouth, swirling his tongue with hers as he picked up the frantic pace again.

Kate was soon crying out, her body shattering around him, and Rick's low groans joined with her sounds to make some of the naughtiest music Rick had ever heard. Her shuddering body squeezed around him and brought him to his own climax just seconds after hers.

Rick collapsed on top of her and Kate's fingertips dug into his back as she held onto him. They held each other for a long time, reveling in the blissful waves of pleasure still rolling through their bodies.

Please tell me if I should keep my pervy thoughts to myself or if I should type up the next few scenes of nothing but more Caskett smut. (Why do I even ask, I already know the answer. I guess I just want reviews. PS: The next chapter won't be posted unless I get them. :-D … but honestly, I want to know about the welcome-ness of the smut.)
