Who's ready for some smutty Caskett? Enjoy!

Chapter Ten

They fell onto his bed in a mess of limbs and lips and bunched up clothing. Kate's dress covered them like a blanket, the long golden material floating over them and spreading so that it covered her legs as she straddled him, making it hard for his hands to find the bare skin of her thighs.

"Get this thing off!" Castle growled in her mouth.

Kate moaned as he bit her bottom lip to emphasize. "Do it yourself," she retorted. Castle growled as he reached for her zipper a second time, inwardly cheering as she didn't stop him.

"I think I will," he murmured against her lips as he yanked the zipper down, making her gasp at the sudden cool rush of air that hit he back as her skin was uncovered. Then she moaned as his hand covered the cool skin, warming it with his fingertips. He swallowed the moan with his mouth over hers before moving down her neck, nipping and sucking at her pulse point, making her writhe and groan in pleasure.

"Castle," she murmured as he focused all his attention on her neck, "you're going to give me a hickey…"

"That's the plan," he mumbled back, his lips never leaving her skin.

"Don't," she sighed. "Or Alexis might-" She didn't even get to finish her sentence before Castle's lips were detached from her lips and he was glaring at her.

"Never mention my daughter during sex," he warned. He said no more but he shied away from giving her any visible hickeys or signs that they were…intimate lest they peak his young daughter's curiosity. Instead, he moved down to her chest, uncovering it slowly as he pulled down the bodice of her dress, moaning as he saw she wasn't wearing a bra. "You're killing me!" he growled, staring hungrily at her breasts. "You weren't wearing a bra the entire night?"

Kate smiled, coyly. "No need; Martha bought a dress with support. Besides, it's strapless, Castle. And I don't have a slip."

"Good, because I might have had a heart attack," Castle groaned, reaching up to catch her mouth in another mind-numbing kiss. As she moaned and leaned deeper into the kiss, his hands went to work divesting her of her dress, pulling it down with one hand while the other roamed her bare skin, touching and squeezing her body as it followed its partner.

When the dress was bunched around her waist, Castle lifted her hips so that she could slide it the rest of the way off. He nearly jizzed in his pants when he saw her barely-there thong.

"What is that?" He hissed in her ear.

"I'm pretty sure you've seen a thong before. In fact, I'm positive that Meredith-"

"No ex-wifes, either," Castle growled in her ear, his hand reaching down to slither underneath the tiny scrap of lace. "And I've never seen one quite this…skimpy."

Kate giggled. "Thongs are supposed to be skimpy, Castle; that's the whole point." She giggled again but that giggle turned to a gasp as Castle ripped the tiny scrap off her body. "That was my favorite," she practically moaned as he wasted no time in running his finger through her sex.

"I'll buy you ten more," he promised, his fingers searching for her clit.

"That'd be…oh!...just a waste of money," she sighed and buried her face in his neck as he began rubbing her slowly. "I might as well go…ahh…commando."

Castle growled. "Don't say things like that!"

Kate smiled, evilly. "Why, Mr. Castle? You going to come in your pants?"

Castle groaned. "Or that!" Before Kate could say anything else, he covered her mouth once again, rubbing her roughly to make her moan and groan and, hopefully, causing her mind to go blank of everything but the sheer pleasure his fingers were causing.

Without preamble, he shoved on of his fingers in her hole, making her buck into his hand. Kate gasped and writhed, screaming into his mouth as his finger pumped in and out of her in a quick pace, making her see stars. At the same time, he used his thumb to continue rubbing her clit, working her up higher and higher until she was sure she was at Heaven's gates. Then, suddenly, he added another finger and she shattered, screaming what sounded like his name into his mouth, her hips shaking and back arching, her legs tightening around his hips and her nails scratching at his shoulders, making him hiss.

Castle brought her down slowly from her high, until she was a pool of satiation on his chest, her breathing rapid and small shivers running through her naked body. Her eyes were open, but glazed, and there was a sheen of sweat over her entire body.

"God, you're beautiful," he marveled, reaching one hand up to move her hair away from her face. "Gorgeous," her breathed, kissing her cheek. Kate smiled, her mouth curving into an almost loving smile, before she realized that she was laying on top of Castle naked and yet he was still fully dressed. She moved away from him, sitting up to look-well, glare-down at him.

"Take 'em off," she said. Her head still pretty much empty from the mind-blowing orgasm he'd just given her.

"Wha-?" he said, his eyes focused on her chest rather than on her.

Kate reached down and tipped up his chin so that he was looking in her eyes. "The shirt," she said, her voice demanding now that she'd come down from her high, "lose it. Pants, too. And underwear. Or else, this," she motioned to her body with both hands, "is going back upstairs and that," she motioned towards his pants, "is either getting a very cold shower or a very lonely hand. Understood." Castle nodded, his eyes wide. "Good," Kate said, swinging her leg off of him and lying down on the bed next to him. "Now strip." Hey, nobody said she couldn't enjoy their one night together, did they? Might as well milk it for all it was worth.

Castle blinked at her for a few seconds before his face split into a wide smile and he stood up from the bed, walking to stand at the end, in front of Kate (and closing and locking the door they'd forgotten to do as they were kissing their way into the room.) He grinned at her and winked, his nimble fingers coming up to undo his tie, sliding the silk knot down and pulling it over his head as Kate watched, transfixed, a dirty little grin on her face. Castle threw the tie at her and she caught it, slipping the loosened tie over her head and letting it fall between her breasts. Castle audibly groaned, his pants growing tighter and she grinned, naughtily up at him, snapping her fingers.

"Continue," she ordered. Castle sighed and his fingers continued down his body, undoing his vest buttons one at a time, his eyebrows raising in turn as each one slipped through the hole, until it was completely removed and he wiggled them at her, making Kate giggle. He threw the vest at her and she slipped it on, leaving it open, but covering her breasts. Castle frowned.

"Stop putting on my clothes!" he whined.

"Well then stop throwing them at me!" Kate mimicked back. Castle's frown deepened, but he got over it quickly as Kate readjusted the vest so that it was no longer covering her breasts. He smiled happily and continued, undoing the buttons on his dress shirt and then pulling the hem out of his pants, slipping his arms out of the sleeves and swinging the shirt around from one of the sleeves, letting it fly behind him instead of at Kate again. Kate eyed his muscular and hairy chest and he flexed for her.

"You liking the gun show?" he asked, cheekily, as he flexed like a muscle man at the circus. Kate rolled her eyes and motioned for him to get on with it, crossing her legs and giving him quite the view while doing it. Castle swallowed hard and rushed to removed his belt and unzip his pants, grinning as he saw Kate's eyes glued to his crotch.

He turned around at the last second and she let out a cry of outrage. He turned his head to smile at her. "Don't worry," he said, "the view is well worth it, I assure you." With that, he began to pull down his pants, letting them pool at his ankles. He kicked off his shoes and toed off his socks before hopping to the side, making Kate let out a tiny chuckle. He turned back and beamed at her.

"Ready for the big finale?" he asked.

"Is it really that hard to hold it in, Castle?" Kate asked, teasingly.

"Not that finale!" Castle practically whined. "That comes later. I'm talking about," he slipped one finger into the waistband of his boxers, "this," he slipped a finger on his opposite hand in, "finale." He pulled down his boxers, giving Kate a great view of his fine ass. She surveyed it with a smile.

"Nice…tattoo," she said, grinning at him. Castle chuckled, looking back at her.

"You haven't seen anything yet," he said, letting his boxers drop to the ground as he stepped out of them. "You ready?"

Kate's eyes widened and she nodded, eagerly. Castle turned and her eyes nearly bulged out of her head. He was big. Bigger than she'd seen in her short twenty years. Most of the boys she'd been out with, mostly under twenty years old, had not been that big, but Castle…there was no mistaking that he was a man, no matter how adorably boyish his smile might be or how childish he acted around his own five-year-old daughter.

Castle noticed that Kate's full, undivided attention seemed to be on his…Little Rick and he coughed.

"Um, Kate," he said, "my eyes are up here. Thanks."

Kate lifted one eyebrow and rolled her eyes. "Just get over here, Castle," she ordered and he staggered forward, falling over her on the bed and kissing his way up her body until he got to her lips. "Mmm," he said, smiling as they pulled away from each other, "you taste so good."

Kate smiled and kissed his jaw, her tongue coming out to lick his skin. "Ditto," she whispered in his ear, making him shiver.

"It is so hot that you say that," he whispered. "I had this girlfriend once-"

Kate placed her finger on his lips, effectively stopping him. "Another rule; no talking about old boyfriends or girlfriends when you're about to enter me."

Castle groaned. "You sound like really good Harlequin," he said, rubbing his stubbly chin over her cheek.

Kate scoffed. "No such thing," she said. "You right better smut."

"Thank yo-hey! What's that supposed to mean?"

"Does it really matter, Castle?" Kate said, giving him 'the look'. The look was something she'd been giving him since her second week at "Casa Castle", after she'd officially gotten comfortable with them. He'd told her to just act like he was a good friend, to be herself around him (as long as "herself" wasn't rude or mean in any way.) He told her that he didn't mind if she teased him or joined Alexis in making fun of him or telling him what she really thought of him, as long as she wasn't too harsh on him. So she did. 'The look' was for when he did or said stupid things that she didn't really feel the need to point out; he should already know what he'd said or done and that it was incredibly stupid or unimportant. "Just hurry up and get a condom on, already."

Castle nodded and reached over into his end table, pulling out a packet of condoms and grabbing one while the rest of them fell to the floor. "I'll get those later," he mumbled, ripping the packet open and rolling it over himself, placing Little Rick at Kate's entrance.

Kate wrapped her legs around his waist and Castle grimaced. "What?" she asked, frowning. "What's wrong?"

"Um…your shoes," Castle murmured. "Usually I think that heels are hot in bed but these ones are kind of poking me…in a very sensitive place."

Kate laughed. "Well then," she replied, huskily, "do you want to remove them for me, Castle?" She rolled her tongue over his name and Castle felt himself get even harder.

"Oh God yes," he groaned, pulling back as Kate unwound her legs from his hips and brought them around to rest in his lap. Castle made quick work of the straps before slowly sliding each foot out, massaging them, gently, and kissing each individual toe. Kate groaned at the sensation, especially when he began kissing his way up one of her legs, stopping at her center to get a taste of her, making her groan and raise her hips to meet his lips. Castle grinned and continued on his way, his eyes meeting hers as he returned to his rightful place above her.

"Hey," he said, smiling softly down at her.

"Enough small talk," Kate groaned. "Get. In. Me. NOW."

Castle nodded, solemnly. "As you wish," he murmured as he entered her for the first and-what Kate thought surely would be-only time. Kate gasped at the feeling of finally being full, as if she'd never known he was missing something her entire life.

She had no idea how she was only going to manage doing this just once.

It became more of an impossibility as he began to move inside her, grunting as she moaned and ran her nails over his back, scratching lightly, then harder as his thrusts picked up speed. "Oh God!" she moaned, burying her face into his neck. "Castle!" Her calling out his name made him thrust faster and harder so she repeated it as a mantra. But, really, more like a prayer. "Castle! Castle, Castle, Castle! Oh God, Castle!" His thrusts increased with each cry of his name and he pushed aside the vest she was still wearing so that he could latch one to one of her breasts, sucking and nibbling, making her nearly scream with the pleasure he was giving her.

Then, suddenly, and surprising even Kate, she tensed, feeling the tsunami of pleasure rush over her body, making her scream, which Castle hastened to swallow so as not to wake the sleeping child upstairs. He followed her shortly after, his groan dissipating in her mouth as he pounded a couple of more times into her, before collapsing. Kate wrapped her quivering arms and legs around him, holding him tightly to her.

She never wanted to let him go. And not just because he'd given her the best two orgasms she'd had in her life.

Okay, that was part of it.

So how did I do? REVIEW!
