A/N: OH MY GOSH! Did anyone see last night's new Castle? Did anyone else notice when Kate said almost EXACTLY what I'd just written a couple days before it aired? When they were spying on Natalie, Kate asked "Why didn't you sleep with me? Her me, not me, me." Though, I had written, "Why don't you want to sleep with me?" so yes, there was a little difference, but still! I'm sorry. I just had to gush about that, it was soo cool!
I'm not very comfortable about posting explicit sex scenes. If I do write them- which isn't often- I don't usually post them because honestly, I'm kind of a prude. But this chapter just came together so easily and I got complaints that I ended my last chapter at the 'good' part, so… FINE, here's the M rated chapter that follows the last. ;-D I'm sorry about my rambling, I was just really hesitant to post this because of the content.

Kate and Rick lay together on her jacket, staring up at the stars. They held each other close and Castle's hands were never still; they skated slowly down her back, over her hip and up her ribs, then down again over her back. This time though, his hand continued down her curvy little backside and then down her thigh. He grasped her leg right behind the knee and hitched her leg up, over his hip. His hand swept even lower, his fingertips grasping her calf excitedly.

"I love your legs," he said quietly, his hand moving over the slender limb. "They are so sexy."

Smiling, she slipped her leg around his back and used it to pull his hips into her body. "And useful," she added suggestively.

"Mmm," he murmured, pressing her body back and moving to kiss her deeply. It was a long, languid kiss, his tongue slipping slowly against hers. Kate's hands moved then, one slipping under his jeans and squeezing his rear end, the other combing into his hair and grasping the back of his head. Rick began kissing his way to her ear and said, "Why don't we take this party inside? I'd like to be able to actually see your body the next time I make love to you."

Kate laughed, even as she turned her head to give him better access to her neck. "And have sex in an actual bed? How terribly pedestrian, Ricky."

"I was actually thinking shower," he corrected. He was currently brushing his mouth back and forth across her collar bone, enjoying the silky softness of her skin against his lips. "You know, the thought of you, all soapy and slippery… is very arousing."

"You keep doing that and I won't be able to make it that far."

So Rick pulled away from her chest, smiled briefly and kissed her mouth before pushing up to kneel over her. Rick grabbed her gun, stuck it in the back of his waistband, grabbed their clothes and closed the lapels of Kate's long coat over her body without letting her dress. Then he stood and helped Kate to her feet before he led her back toward the house, his arm wrapped tight around her shoulders. At one point, he pressed his lips to her hair, kissing her head and breathing in the scent of her shampoo and the beach on her hair. He led her inside the house and straight to his bathroom, only stopping to lock the back door upon entering the house. The only time he let go of her was to lean into the stall and turn on the shower.

Rick then turned back to face her, dropping the clothes he held and setting the gun on the counter. He looped a single finger into a pocket of her jacket and yanked her forward. She stepped closer to him but left some space between their bodies. A tied belt around her waist was the only thing keeping her coat closed and Rick easily pulled the long strip form it's loops, dropping it to the floor with the other discarded clothes.

Kate would have tossed the jacket to the floor too, but she sensed Rick was having fun undressing her. So she let him slowly push open the lapels of her coat, revealing her bare body an inch at a time. When the coat finally hit the floor, both were breathing faster in their mounting excitement. And Castle took his time as his eyes swept over her body, lingering on the red roses tattooed just outside each breast. They had been hidden by her bathing suit with the wide straps but he knew a string bikini would have left most of the tattoos visible. He put his hands on her ribs, his thumbs sweeping over the tattoos. His gaze ticked up to her breasts and he thought they looked like they wanted attention too; he bent forward and took one peak into his mouth, his hand moving up to cup the other. But Kate could only take a moment of the torment before she put her hands on his shoulders and pushed him back.

Rick stepped back, standing up straight and watched Kate as she unfastened his pants and pushed them down. When they were both naked, Rick took her hand and led her into the shower stall. He placed Kate in the very center where the water fell from straight above and washed down her head, her shoulders and then her body. When she was totally wet, Rick sat on the built in shower bench, pulled her to stand between his legs and soaped his hands. He began with the more innocuous parts of her body, rubbing soap into her arms then her legs. He turned her around to wash her back, at one point kissing the tattoo at her waist before it got soapy. Turning her around again, he just looked at her for a long moment before soaping her stomach and finally her breasts. Rick moved one of his own feet between hers and nudged them apart. When she stood with her feet spread wide, he slowly slipped his soapy hands between her legs. As he touched her, Kate's eyes slid closed and she had to brace her hands on Castle's shoulders for balance. And then, a moment later, she used her grasp to pull Rick forward, guiding his lips to the peak of her breast, which he happily took into his mouth.

When all the soap was washed away, Rick finally slid a finger into her. Every time she moaned or made any kind of noise, Rick did whatever he'd just done again- just to hear her make those noises some more.

He was so hard, he wanted to bury himself inside her and stay there for a month, but more than anything, he wanted to bring Kate pleasure, however he could accomplish it. And due to his efforts, she was soon panting, making sexy little noises at the beginning of every exhaled breath. So he slipped another finger inside her and quickened his pace, using a thumb to work the most sensitive part of her.

Kate's hands fisted in his hair, clutching him and pressing him harder against her breast and soon he could feel her body convulsing around his fingers as she made loud whimpering sounds of pleasure. Her legs buckled and she might have fallen but his hands on her held her up.

As soon as his fingers left her body she moved, straddling Rick's lap on the shower seat. Taking him in her hand, she positioned him right where she wanted him and sat down on him, taking him easily all the way inside her body. Rick's fingertips dug into her back when an aftershock of her pleasure went through her and squeezed her body around him. He used his grip on her to pull her down harder, grinding their bodies together and they both savored the feeling of him filling every inch of her. When he rocked his hips experimentally, she moved with him, increasing the movement and making Rick groan. Kate smiled, loving the sound of his pleasure. So she concentrated for a moment and contracted her inner muscles around him.

Gasping, his fingers again flexed into her back and he warned her, "If you do that again, I won't last very long."

Her smile turning impish, she did it again anyway and quickly began moving with him when Rick began rocking his hips in and out of her. And despite the threat, it was a long while later that he buried himself in her, his face in her neck and came with a loud moan, a perfect harmony for Kate's gasping whimpers of release.
