A/N: Well here it is, I am evil no longer. The chapter many have been waiting for very patiently. Please note that the rating has been changed to 'M'. Apologies if that means I lose some of you, but I felt it was where the story needed to go…oh who am I kidding, I just wanted a chance to write a little shameless smut for my favorite couple. This is my longest chapter yet. It kind of got away from me. I've rewritten it twice and have proofread until my eyes could take no more. I truly hope it lives up to expectation, and if not,

Disclaimer: I sadly do not own any of the characters. If I did, this chapter would have already occurred on the show, but in a respectable manner. It's ABC not HBO.

Rick stood motionless as Kate moved onto the next button and the next until she had opened the shirt to reveal his bare chest. She ran her hands up and down his chest a few times and then leaned down to place a few kisses on his collarbone. He sucked in a breath at the first kiss and thought he would lose consciousness as she continued her assault.

"You know Rick," she said as she pushed the shirt off his shoulders and it hit the floor. I've wanted to know what you looked like without clothing for years.

His gaze met hers with fierceness. Had she just said years? What the hell!

As if she could read his mind, "Yes, I said years Rick." As she started to lean forward and place a kiss on the hollow of his neck. "I've had enough of the games, I'm ready for something more." And with that she wrapped her arms around his neck and kissed him on the lips. It wasn't a light peck on the lips either. It was a full make your knees go weak kiss. Rick wanted to touch her so badly. He wanted to strip her down and bury himself in her, but apparently she had other plans.

"Kate, please…", he said in almost a whimper.

"Have patience Rick," she said as she released him and turned to walk towards the bedroom. She turned back realizing that he was still rooted in the spot she left him. She walked back over and grabbed him by a belt loop and started to drag him with her. "This will only work if you go with me," she said with a sexy smile. He smiled and followed her towards the bedroom.

When they entered it was not what Rick expected. He'd expected just solid colors and a few pictures. What he saw was just so much more, so not the Kate he saw every day, but the one he always knew existed. The walls were a light crème color, but the far wall had a mural of a tropical paradise painted on it. The dresser with more girly knickknacks than he could have ever imagined Kate Beckett owning, and a little sitting area over by the mural where he only assumed she sat and read in her down time. There were the normal pieces like a vanity and dresser all made out of what looked like oak. But what really got his attention was the four post bed. It looked like something out of a fairytale. Solid oak with a canopy that had paper thin white curtains draped over it. He now understood the purpose of the mural, the room looked like a mini paradise. Never in a million years would he have pictured Kate's bedroom like this. He finally realized that he was being stared at by the beautiful woman in the room,

who in the time he was looking around the room had removed her shirt and pants and was standing there in just a red lace bra with matching panties. At that moment he lost all coherent thought.

"You know Rick, if you'd like some time alone with my room I guess that could be arranged," she said with a smile, but a hint of unease which she quickly masked.

Knocking himself out of his daze he said, "I'm just taking it all in. I'm not used to seeing this side of you."

"Well if you play your cards right you'll be getting to see a lot more of me very soon."

"I guess it's a good thing I'm really good at playing cards," he said giving her a sexy little smile that almost turned her into goo.

"Get on the bed and lay down Rick," she said as she motioned to the oversized bed.

He didn't have to be told twice, well occasionally. Okay so maybe he wasn't the greatest at listening to people, but when Kate Beckett tells him to get in her bed, he's going to listen.

Once he was lying down she climbed on the bed and straddled him. "Now put your hands up by the headboard."

He did as he was told and as she looked at him she could see the fire and the passion in his eyes.

She pulled the cuffs out of what seemed like thin air. He thought to himself, I need to figure out where she keeps those things.

She put a cuff around one wrist and then she looped the cuffs around one of the posts in the headboard and attached the other on to his remaining wrist.

As soon as she knew his hands were secure she began her campaign. She slowly worked her way down his body, kissing every inch until she had him squirming and pulling against the cuffs, "Careful Rick, don't want to hurt yourself."

"I think we should do the cuffs another time, maybe tomorrow, maybe a week from Tuesday?"

"Oh where's the fun in that Rick," she slowly kissed her way back up his body and whispered in his ear, "and I haven't forgotten that your safe word is apples."

Oh…..! He thought, she's going to be the death of me. He wasn't prepared for what happened next though.

"You have way too many clothes on Mr. Castle, I think we need to take care of that problem." She reached for the button on his pants. As she pulled them off she made mental note that he was a boxers man. Once the pants had been discarded she looked at the man in front of her and could see the evident arousal. She grabbed the edge of the boxers getting ready to pull them off as well.

"Wait, Kate are you sure about this?"

"I'm sure," she said as she tugged off the boxers to reveal his impressive package. And it's all mine, she thought to herself with a smile.

She continued her study of his body working her way downward. As she reached his navel she reached up and scratched her nails down his chest which had him shivering in response. When she reached his groin he looked down just in time to see her take him completely in her mouth. The realization of what had just happened sent Rick into overdrive. He threw his head back with a gut wrenching growl. As she started to move her mouth up and down his shaft he lost himself in the moment. Her mouth was warm and moist against him. He honestly didn't think there was anything better than her mouth on him.

"Oh, go….. Kate!" he wasn't going to last very much long. It was downright embarrassing that he wasn't even going to last another minute. "Kate, you have to stop or else this is going to be over before it even begins."

She paused momentarily to look up at him. As he looked down at her the sight of her head just inches away from his shaft was an image that he was never going to forget.

As their eyes met she just smiled, "Rick….this hasn't even yet begun," and with that statement she took him back in her mouth while gently cupping the rest of his unit. Rick's head flew back on the pillow and let out a growl that could more than likely be heard throughout the building. He began to thrust his hips forward and moments later he found his release. Kate lifted her head up and moved up Rick's body placing kisses and small love bites along the way. Once she reached his face she took a moment to look at him. His eyes were closed, head still against the pillow, apparently still trying to gain some composure. He seemed to be doing that a lot today.

"You know it's really creepy staring at the guy handcuffed to your bed."

"I like to think it's a little seductive or erotic," she said with a grin placing a gentle kiss on his lips.

"Great word choice," he said opening his eyes, "but I would have gone for kinky."

"You and the word kinky," she said shaking her head as a small laugh escaped from her lips.

"So now that you've had your fun can you please release my hands Kate? I want to touch you and these," he said moving his hands and the cuffs, "are kind of putting a damper on my ability to do just that."

She slowly sat up on him causing a delicious friction that was slowly driving him mad. "I suppose since you've been a good boy and played along with my little game."

He was still trying to catch his breath from the pleasure she had just given him gave out a sigh of relief, but then Kate leaned down to whisper in his ear, "You are to wait until the cuffs have been removed from both wrists and then have been placed back on the nightstand to touch me. Do you understand Rick?"

He gave her a single nod. She sat back up and produced a key out of what seemed like thin air. She leaned over him letting her bra clad breasts hang right over his head. He lifted his head slightly and nipped at one through the lacy fabric.

Kate gasped at the sensation his action caused. She momentarily forgot what she was doing.

"Rick, if you want to be free of these cuffs you'd better hold off on that for a few minutes."

As soon as she freed his other hand from the cuffs she unwound them from the bed, but she didn't immediately put them away. Rick started to reach for her, but she stopped him, "No..no…no…Rick, I haven't put…", but she was cutoff when Rick grabbed to cuffs out of her hand and threw them in the general direction of the table. There was the faint sound of something breaking, but neither of the really paid any attention.

Rick sat up quickly with Kate still straddling him, wrapping his arms around her and bringing her in for a passion filled kiss that made them both moan with pleasure.

He was thankful that most of their clothing was already gone. There was only the barrier of her bra and panties standing in his way, and those needed to be taken care of quickly. He broke the kiss and started slowly placing kisses down her neck and moving downward towards her breasts. But this position wouldn't do for what he had in mind. It was only fair that he pay her back for the pleasure that she gave him only moments ago.

Before she knew what was happening Rick had moved them and she now had her back pressed against the bed and he was sprawled out on top of her with a boyish grin that made her smile every time she saw it. Unclasping the front of her strapless bra he took it off of her and threw it over his shoulder. He continued his kissing assault, taking time to relish in the perfectness of her breasts and the erect nipples that were calling to him like a sirens song. It was something that he was unable to accomplish earlier when he was cuffed and that pesky bra was in his way. He continued his downward track until he reached the top edge of her panties, "Well, I think you're still wearing way too much clothing," he said gently pulling the lacy item over her hips and down her legs. After discarding them as he had done her bra he resumed his exploration of her lower half. When he finally reached the area between her legs he gently placed a kiss on her sensitive flesh.

"Ohhh….I need you in me now, Rick." She said with such urgency that Rick looked up and didn't know what to do for a split second.

"But…"

"Now is not the time to think Rick!" she literally screamed at him.

He moved back up her body and pulled her in for an earth shattering kiss. He positioned himself at her opening and sheathed himself in her warmth in one thrust.

"Ohhhhhh…."they both let out simultaneously.

Rick stayed still for a moment so she could adjust to him. She was so tight, he knew he wasn't going to last very long and only hoped that he held on long enough to give her the pleasure that she wanted.

Kate couldn't breathe, it was like they were made to fit together. He was so big, she always had a sneaking suspicion that he was very well endowed, but the reality was just so much more. But this staying still crap was just not going to fly with her. She wrapped her legs around his waist and looked at him, "Please Rick," she said in a small breathless voice.

It was hard for him to deny her anything especially when she used her sexy voice. He started to move very slowly inside of her, but quickly picked up the pace. But soon he could feel his control slipping.

"Kate, I can't hold on much longer," Rick said as he thrust into her over and over again.

"Then don't," she said as she let out a cry of bliss as he thrust into her again

He leaned in for a kiss and increased his efforts and as he began to feel her wall tighten around him he lost all control. Two more thrusts and they found their release at the same time.

Rick slowly pulled himself from her and rolled over to lie next to her. He took a moment to enjoy the fact that he was lying in a sweaty tangled mess in Kate's bed with the woman herself, both of them trying to gain some form of composure before either one spoke.

He was the first one to speak, "That was just….wow."

"Right there with you Castle."

"Hey," he said as he rolled over to face her, "I thought we agreed to call each other….." He was cut off by Kate rolling over and silencing him with a kiss. What started off as an innocent kiss quickly turned into something more. As his tongue ran across her bottom lip, she let out a sigh and allowed him access. She rolled them so that she was on top of him. Straddling him she could feel his erection already starting to grow and pressing against her core. She wanted him inside her now. Kate quickly lifted her hips up and impaled herself on his shaft, letting him fill her up to the hilt. They both moaned at the intimate contact and took a moment just to bask in the realization that this was actually happening. She broke the kiss and sat up slowly, giving a small laugh when he let out a small whimper of protest for breaking the kiss. And then she started to move, slowly at first, but eventually picking up to a steady pace. Rick grabbed onto her hips to help guide her, not that she needed much help. She was driving him over the edge quickly. Their moans and gasps for air filled the room. She grabbed onto her breasts and arched her back as their movements became frantic. He threw his head back onto the pillow, but kept his eyes open looking at the woman moving on top of him.

"Rick, I'm going…" she hastily said as she moved her body as she began to ride the waves of her second orgasm of the night.

He could feel her start to pulse around him and with a couple more thrusts they brought each other again to a state of bliss that neither knew existed. "Kate…." He groaned as he found his release.

Kate collapsed against Rick unsure if she was going to ever be able to move again.

"You're crushing me Kate, I can't breathe." Rick said with a laugh.

She slowly sat up giving him a playful shove in the chest, "You'd better watch yourself if you ever want this to happen again," she said with an evil grin.

He held up his hands in surrender, "I'll be a good boy I promise," he said with a smile.

She looked down at the man who had helped her break down the wall she had hid behind for so long. "Well don't be too good, takes the fun out of things," she said as she thought about what they were going to do next.

He looked up at the woman who had stolen his heart long ago. A vision as she sat on top of him completely exposed. He'd waited a long time for this to happen and it wasn't going to be ending anytime soon.

-C/B-

They had stayed in bed or close to bed for basically for the past two days. Not just making love, but also talking, taking showers, and having a movie marathon of all things.

"We're going to have to eventually get out of bed you know?"

Rick gasped in mock horror, "What? Lies! "

"Tomorrow we have to go back to work, or should I say I have to go back to work."

"What I do there is work too. I'm a civilian consultant."

She shook her head and gave a little laugh, "that's a glorified way of saying you're a regular guy following around a detective."

"True, but I've actually been very helpful in some instances."

She moved her hips side to side a few times causing him to suck in a breath and grow hard once again, "You actually have been very helpful Rick, not just at the precinct, but other places too," she said with a smile that said she knew exactly how Rick would take that statement.

"How about I run home and get a few things and then I can come back here," he paused to pull her down to him for a lite kiss, "and we can pick up where we left off and then get up and go into the precinct in the morning." He released her and she sat back up.

"Okay, but remember we also have to set some ground rules as to how this," Kate said pointing between the two of them, "is going to work. This was a slight departure from how I thought this was going to end."

"Well how did you picture this experience ending?" he said just a little curious. Oh who was he kidding, he was extremely curious.

"Well, the original plan was for me to still be mostly clothed and you down to your boxers, and this having ended two days ago, but as you can tell we went way past that."

"Are you saying you regret this?" Rick said looking just a little bit hurt.

"No…it's just we have to be careful. We don't want Gates finding out about any of this, she'll throw you out of the precinct so fast you won't know what hit you. The guys and Lanie will never let us live this down." She looked over to see he had let out the breath that he was holding. "Let's just take this one day at a time, okay?"

"We can be undercover lovers," he said with a sexy grin and he gave her a little eyebrow wiggle," but people are going to find out eventually Kate, it's only a matter of time."

A/N: So there you have it. Please drop me a line and let me know what you thought. I have never actually written anything remotely smutty before so I'm kind of worried. Too much? Too little? Complete crap? There will be one more chapter to this story. Maybe two, but we'll just have to see. Hopefully you won't have to wait so long for that one. I'm contemplating a sequel to this, or maybe I'll just continue writing chapters to this story. Or should I just let this story just be filed away in the big precinct in the sky? I guess those are all questions for a later A/N. As you've already realized I'm terrible at updates, but hopefully as the month goes by I will have more time. Reviews whether good or bad motivate me to write. I love hearing what people have to think.
