AN: The devil on my shoulder, by the name of JJ, told me to make this chapter M, so enjoy. He was also shaking his head that I didn't do this sooner. I deleted two guest reviews because I don't really care for what they said (especially one about Kate). You can say what you want about how I should write a story, but when you attack Kate that's not right. I also want to say sorry for not being clear it seems as to what Kate's plan is. She's not with Josh now. She's just pretending to be with him so that Bracken doesn't harm her or him. I made it a little clearer in this chapter. Those reviews are helpful, since I don't want anyone to be confused. Anyways, enjoy this chapter and if you're not into the M storyline, you're welcomed to wait for the next chapter and not read this. Enjoy :)

They had tracked down the bomb and he had disabled it with just seconds to spare. She hugged him tightly before she kissed him and if he could save the world every day just to have her kiss him like that, he would do it. The moment was quickly over though and they headed back to the precinct, where they went their separate ways. Her and Josh had been pretending to be with each other, to protect themselves. He took extra shifts at work, so he didn't have to see her often, and she spent time with Castle. They hadn't crossed that line yet, since she was never sure of who was watching them. They shared kisses in private and had gone out to dinner and the movies a few times. Josh came over for dinner once a week and if he stayed over, he slept on the couch. He still couldn't tell her who hired him and who killed her mother, but she was hoping that he would crack sooner rather than later.

Today though, she wasn't looking for her mother's killer. She was looking for Royce's. Of course, Castle wasn't going to let her do this alone. He booked a ticket to LA and bumped her to first class. When she saw him, he knew that she wasn't happy with him being there, but she didn't kick him off the plane and didn't ditch him once they got off of it. They didn't get very far today, but they made some progress in finding Royce's killer.

Right now, he was opening the bottle of wine that he had picked up before they headed back to the hotel and pouring it into two glasses as they discussed the case and why exactly Royce came to New York, for the home field advantage. Of course, that ended up not in his favor in the end.

"I was so in awe of him, Castle, when I first met him. I just hung onto his every word. And later, I realized he was just making up stories to mess with me." They shared a smile and there was silence for a few moments before Kate broke it again. "I can't believe that I'm never going to see him again."

"You know what I thought when I first met you?" He waited until he had her attention, which wasn't long. "That you were a mystery that I was never going to solve. Even now, after spending all this time with you, I'm still amazed at the depths of your strength, your heart...and your hotness."

"You're not so bad yourself, Castle." They looked at each other for a few moments, getting lost in each others eyes. "Is that why you fell in love with me?"

"Cause of your hotness? Yes," he teased, which caused her to laugh and that cause him to smile.

"Glad to know we fell in love for the same reasons."

"I knew you kept me around to be your eye candy," he teased again. There was silence for a few seconds before she spoke. "Why did you keep me around, Kate? We both know that you could have kicked me out if you really wanted to."

She took a sip of her wine before she placed the glass back down. "Because I trusted you. You saved me, when we were in that woman's apartment, by tackling me to the ground when you saw our killer with a gun. Then you distracted him in order for us to take him down and get out of there alive. Even though you weren't a cop, I trusted you with my life from that point on. I knew you'd always have my back and I know that's never going to change."

"I'll always have your back, Kate. Always. I'd take a bullet for you any day of the week." He leaned in and pressed a soft kiss to her lips. "We should probably get some sleep."

She nodded before she got up from her spot on the sofa and headed towards her room. Even though that they were...well they didn't have a name for it, she still didn't want to get used to sleeping with him while she was "with Josh". She turned back around and saw that Castle was still on the sofa. She gave him a smile. "Night, Castle."

"Night, Beckett."

She closed the door and rested against it for a few seconds. She wanted to go to him, wanted to show him how much she loved him. She wasn't cheating on Josh, since they weren't in a real relationship and she highly doubted there was someone here spying on her to show The Dragon that she wasn't with Josh anymore in the way he thought they were. She opened the door and expected him to still be on the sofa. She instead saw him closing the door. "Castle," she said before the door closed.

He stopped closing the door and opened it to where he was facing her and looking at her. She looked at him and before she could stop herself, she ran over to him and jumped into his arms. She wrapped her arms and legs around him before she captured his lips in a passionate kiss. He didn't waste anytime with parting her lips with his tongue and exploring every inch of her mouth before tangling his tongue with hers. He felt the moan that escaped her and into his mouth and it caused him to hold her tighter to him.

Since it was just them, he didn't bother closing the door before carefully walking them to the bed. She angled her head, to deepen their kiss, before he had the chance to lay her down. He let the kiss go on for a few more seconds before he broke it. He didn't go far though. He trailed his lips down her neck, nipping as he went. He was careful, where he wouldn't mark her skin. One, since he knew they would be in contact with possible suspects tomorrow and because if they did head home tomorrow, he didn't want anyone seeing it on her neck. That didn't stop him though from sucking at a sensitive spot on her neck for a brief second. The moan that came from her was definitely worth it.

Kate had loosened the hold that she had around him, moving one of her arms to her side, while the other ran her fingers through his hair. She loosened her legs from around his waist, so that it would be easier for him to move if he pleased. He tore his lips from her skin when he felt her tugging at the hem of his shirt. She took his shirt of of him and tossed it to the side, not caring where it went. Kate then leaned up to capture his lips in another passionate kiss. She moaned into his mouth when she felt the squeeze to her breast. She was so into their kiss that she hadn't noticed that his hand hand sneaked up her shirt.

His hand moved from her breast and his fingers went to the clasp of her bra. He undid it before he broke their kiss again. He took her shirt off of her, tossed it to the side, and then slid her bra straps down her shoulders. He took it off and tossed it to the side as well, not caring where it went. His eyes traveled down to the newly exposed skin, but before he leaned in to give her breasts the attention they deserved, he looked at her.

"You sure about this?"

"Yes, Rick. I'm sure." She used his first name to emphasis that she was serious about wanting to take this next step with him.

He pressed a soft kiss to her lips before he let his lips travel down her throat. His lips made it to the middle of her breasts and he nipped at the skin. He then made his way to her left breast. He teased her nipple with his tongue before he pulled it into his mouth to suck hard on the sensitive skin. He would have grinned when he heard her moan, but his mouth was a little busy at the moment. When he was satisfied, he moved to her right breast and gave it the same attention.

"Castle..." He was driving her crazy and he hadn't even taken her pants off yet.

He looked up at her, making sure that she was saying his name out of pleasure and not because she was having second thoughts about this. Even though he had seen that it was indeed pleasure, he moved his mouth from her nipple and trailed his kisses downward. He often dreamed of what Kate Beckett's skin felt like against his lips, what sounds she would make, how she tasted, where she was the most sensitive (other than the obvious places), and now he was finally finding out. When he got to her pants, he moved her legs that were loosely around him before he took her pants off of her. He was tempted to take her panties off as well, but he was going to tease her a bit first. His lips placed nipping kisses across her waistline as two of his fingers ran up and down the length of her. The moans that were coming from her were making him slowly forgetting his whole teasing her plan and just taking off the rest of his clothes and giving them what they both desired.

He moved his lips from her skin and moved a bit, so he could take his pants and his boxers off, kicking them to the side. He then moved his hands to the last article of clothing and slide them down her gorgeous long legs. He tossed them to the side.

"I was going to take your clothes off for you."

He smirked. "Next time." With that, he moved in between her legs and took her into his mouth. He groaned against her, loving the taste of her and knowing that it was him that was making her wet. He felt her fingers in his hair, as if to say to keep him there. He released for a few seconds, only to run his tongue up and down her a few times. He circled her entrance with his tongue and let the tip of his tongue enter her a few times before making his way back to her clit. He moved his one hand, so that he could easily let two of his fingers enter her.

"Castle!"

He groaned against her skin and sucked on her harder, letting her know in his own way what he wanted, he wanted her to have her orgasm with his mouth and fingers. It wasn't much longer before she did have her orgasm. She screamed out his name as her head tilted back and her legs twitched. He moved his mouth from her, but kept his fingers inside of her for a few seconds longer, making sure that she had an amazing orgasm. One of what he hoped to be many that night. He removed his fingers from her and brought them to his mouth, sucking her essences off of them. He then moved so that he could place soft kisses to her beautiful face.

"God...Castle."

He smiled against her skin. "Doing okay there, Beckett?"

"Perfect." She opened her eyes and looked at him. "But now it's your turn." With that, she flipped them over so that she was now on top of him. Before he could protest, she captured his lips in a passionate kiss. He knew that she wanted to return the favor, but he wanted to have his orgasm when he was inside of her. He'd let her explore his body for awhile though. Until it got too much where he had to be inside of her.

Her lips traveled down his neck and like him, she made sure that she didn't mark him. For him, if she marked him it wouldn't matter so much. He could say he had a one night stand in LA, but she knew that it would be better if she didn't mark him. As she made her way down his neck and to his chest, she found a few of his sensitive spots and she was loving the groans that were coming from him. She found the spot right above his right nipple really sensitive and she made sure to give it some extra attention. She ran her tongue over his nipples before she trailed her lips down his chest. Another sensitive spot was right above his belly button, which for some reason she found amusing. She didn't laugh though, she just smiled against his skin.

It wasn't long before she gently took him into her mouth and started sucking on him. She hummed around the length of him every so often, which caused a louder groan to escape him. She loved that and she kept that in the back of her mind for future reference. She was just about to start sucking on him a little harder and a little faster, when she felt him tugging at her hair.

"Kate, stop."

She moved her mouth from him and gave him a confused look. "Do you not like that? Because the sounds you were making..."

"No, I love that...but I want to be inside of you."

She smiled. "That can be arrang..." Before she could finish her sentence he flipped them, so that she was on her back again.

"You can ride me another time," he winked at her before he captured her lips in a passionate kiss. As his tongue entered her mouth, he positioned himself and entered her in one swift motion. She moaned into his mouth and let the kiss go on for a few more seconds before pulling away.

"God, Castle...you feel..."

"Amazing..."

She nodded, agreeing that she was feeling the same thing he was.

"Are you on..."

"Yea, we're good," she got out before she leaned in to kiss him passionately once more. She teased him with her tongue, just a bit, running it over his top lip before letting it enter his mouth. She then bucked her hips into his, letting him know that he could move.

That's exactly what he did. He started moving deeply inside of her, keeping the pace somewhat slow at first, but then speeding it up just a little bit after a few strokes. He loved that she was moving her hips with his and that her legs had moved to wrap around him again. He moved his lips from hers when breathing became an issue. He picked up the pace more, when he felt closer to losing control. He could feel that she was close too. Her moans were getting louder and he was pretty sure that was a sign as well.

"God, Castle!" She screamed when she had her orgasm. No one had ever made her scream before. Not like Castle.

As soon as he felt her let go, so did he. "Kate!" He kept moving his hips for a few more seconds, she had stopped moving hers, before he fell against her. He made sure not to crush her though. "I love you...I love you, Kate," he whispered breathlessly in her ear.

"I love you too, Castle."
