YOU HAVE NO IDEA

The case was finally over, and she would be rid of him. "Well, I guess this is it," Kate told him.

"It doesn't have to be. We can go to dinner. Debrief each other," Rick offered.

"Why, Castle? So I can be another one of your conquests?" Kate asked, her eyebrow raised.

Rick grinned at her. "Or I could be one of yours."

"It was nice to meet you, Castle." Kate held her hand out to shake his.

"It's too bad," Rick told her. "It would have been great."

Kate bit her lower lip and moved in next to his ear. "You have no idea," she whispered, walking away from him, putting extra sway in her hips just to taunt him.

~oo0oo~

Kate knocked before entering Montgomery's office. "You wanted to see me, sir?"

Roy knew this wasn't going to go over well. "Yeah, I just got a call from Mayor Weldon. Apparently you've got a fan."

"A fan, sir?" Kate didn't understand.

"Richard Castle. Seems he's found a character for his next main character. A tough but savvy female detective."

Kate thought about it and tilted her head. "I'm flattered?"

"Don't be. He says he needs to do some research."

Kate caught on to what Roy was telling her. "Oh no!"

Roy contradicted her. "Oh, yes."

"Sir, he's like a nine-year-old on a sugar rush. Totally incapable of taking anything seriously."

"But he did help solve this case," Roy pointed out. "And when the Mayor's happy, the Commissioner's happy, and when those two are happy, I'm happy."

"How long, sir," Kate asked, knowing she had lost this argument.

"That's up to him." Roy nodded to Rick standing behind her.

Kate turned, and there stood Rick with a smirk that she wanted to slap right off his face.

~oo0oo~

"Mr. Castle, be advised if you get injured following Detective Beckett around, you cannot sue the city. If you get shot, you cannot sue the city. If you are killed…"

Rick interrupted him. "My lifeless remains can't sue the city."

"Your heirs, Mr. Castle, your heirs cannot sue the city."

By then, Kate had had enough of this and wanted to leave. "Do I have to wait for him to sign, or can I shoot him now?" Kate asked him and got Rick to smile at her.

Kate got a call. "Right, be right there."

Rick was enthusiastic, looking forward to it. "We got a case?"

"No, I have a case. You have paperwork. Oooh." Kate left him to his paperwork.

~oo0oo~

"Thought you ditched me back at the Precinct, didn't you?" Rick stood outside of the floor where Kate was going. The door started to close on her, causing her to put out a hand to stop it. She was shocked.

"You're right, Castle. My bad." Kate headed for the apartment she wanted to see. She eyed him. "How long can I expect you to follow me around?"

"I don't know," he replied. "I never know when inspiration strikes."

Kate looked at him. "I thought I was your inspiration?

"Oh, you are, in so many ways," Rick told her.

~oo0oo~

Kate was home from work, thankfully. Castle hadn't been nearly as bad as she thought he would be, but that wasn't the point. He was following her around. That in itself was bad.

She was about halfway through her Chinese dinner when there was a knock on her door. Groaning, she got up to answer it. She just opened the door, not bothering to see who it was.

"Castle!?" It was him. Her first thought was how did he know where she lived. The next was wondering why he was here, bothering her and interrupting her dinner.

Castle didn't waste a second and didn't say a thing. He stepped into her personal space, wrapped his arms around her, and kissed her. He kept on kissing her.

At first, Kate didn't kiss him back – she was too shocked – but soon she did.

Castle broke from the kiss and smiled at her. Then he kissed her again and walked them farther into the room. He kicked her door closed. He was busy kissing her.

Kate returned his kiss. She'd been kissed before, but never anything like this. This… was magical. She was kissing him back and enjoying it.

Then she felt him move his hands to her front and begin unbuttoning her top. She was letting him.

Her top was off, and his hands moved back around her as he kept kissing her. Then they were on the back of her bra, unfastening it. Her bra was off, and he continued kissing her.

Then he risked it and stopped kissing her. He bent down to take a little pink nipple in his mouth. Kate held his head and moaned as she felt his tongue when he suckled her nipple.

He switched nipples and gave the other one equal attention. Kate looked down at his head as he suckled at her nipple. Then he bit it. HE BIT HER NIPPLE! She yelped and pushed his head away, staring at him.

Rick was scared. He had taken it too far by biting her nipple. Then she grabbed his head and kissed him passionately. It was a hard kiss, and he was kissing her back.

~oo0oo~

Kate woke up, and she was in bed, her bed. She thought about how she had gotten here and suddenly remembered: it was Castle.

He had carried her here. Carried her! He had placed her on the bed and got to work on her pants. She even lifted her ass off the bed to help him pull them off her, followed by her panties. She had no idea when her shoes had come off.

He spread her legs wide, exposing her to him. He had wasted no time in going down on her. He ate her pussy. She had an orgasm eventually, but he didn't stop; he kept eating her pussy. Then he put two fingers inside her, and she loved when he did that.

That was when everything changed. She'd had an orgasm while he stroked her with his fingers inside her, followed by another one. By now, she had lost her mind, but she remembered him continuing to eat her pussy. Kate didn't know how many times she'd come. All she knew was that it was a lot.

Her mind returned to her. He had hold of her ankles and was fucking her. She looked down and watched his cock gliding in and out of her body.

She had another orgasm just as he did. He came inside her. At the time, she didn't care about that. What she did care about was him spinning her so that she was on her hands and knees.

Then she felt him inside her. He was fucking her from behind. Kate looked back at him, watching him. She couldn't help herself and began moaning and groaning.

She'd had another orgasm while he fucked her from behind. Then he did the impossible. He felt her at her ass. He was planning to fuck her ass. She had told him, "YES, FUCK MY ASS."

So, he did. He had fucked her in the ass, and she loved it. By the time he climaxed inside her ass and had pulled out, she was betting her ass was wide open.

~oo0oo~

It is now safe to read if M-rated material is not to your liking.

~oo0oo~

Kate woke up, looked the bed over, and came up empty. She moaned at the loss of him. Then it hit her – she had fucked him! She was a conquest. "DAMN IT!" Frustrated, she pounded the bed with both fists. She had allowed him to fuck her! She had enjoyed it, but that wasn't the point. She had allowed herself to be fucked by Castle. She was a conquest of his. She was angry with herself.

Getting out of bed showed her how sore she was. It was a good kind of sore, if there was such a thing, but she was still sore. She took a shower and checked her pussy. It was red and painful.

She saw a wet spot on her bed, a big one like she had been sweating. There was also one where she thought her pussy was. Where his cum had leaked out of her.

"DAMN, DAMN, DAMN!" She was on the pill, but that wasn't the point. She had allowed him to climax inside her, leaving his cum.

~oo0oo~

Kate went into work that morning and wasn't looking forward to seeing Castle. She was sure he was going to gloat.

She noticed him getting off the elevator and did her best to ignore him. That was until he stepped over, tilted her head up, and kissed her. He said, "Hi," and then kissed her again.

Most of her thoughts about being a conquest evaporated. Still, she needed to know. "Castle?" She was all set to ask him about last night, but she was interrupted when Captain Montgomery came over to their area.

Roy turned to Esposito. "Where are we on the phone records?"

"Have them right here." Espo handed the folder over to him. "The ping of the phone puts it at or near the building at the time of our killing."

"Find this Brent kid and bring him in for questioning," Roy ordered.

Kate had to start her work and not talk to Castle about last night. She went all day long without a chance to speak to him.

~oo0oo~

Kate was home. She never got a chance to talk to Castle, and she didn't like that. She wanted to know if it was a one-time thing, a one-and-done. Then there was a knock on her door. She got up and answered it. "Castle?" He was the last person she expected to see.

Rick walked into her personal space, kissed her, and continued kissing her. At first, she didn't kiss him back, but soon she did. So he walked them into the room and kicked the door closed.

He was kissing her, and she liked it. But she had questions. So she pulled away from him. "Castle, why..." But she had a problem. The man still wasn't finished, and he kissed her. His hands moved to her front, where he worked on her buttons, and Kate let him.

When he was working on her bra, Kate stepped away from the kiss and tried once more. "Castle?" Except her bra came off, and he attached himself to one of her nipples. She moaned and held his head in place; all thoughts of asking him her questions were gone.

~oo0oo~

Kate woke up from having sex with Castle yet again. She had enjoyed it immensely. She looked all over the bed, flipped the covers, and came up empty. She even looked under the bed! She groaned. She was going to have to wait for her questions.

Annoyed, Kate sat up and ran her hand through her hair, and then she saw him. He was buttoning his shirt. "Castle, wait, please."

He stopped what he was doing and turned to face her. She looked up at him. "What is this?"

Rick raised an eyebrow. "It has been a long time for you, hasn't it?"

"Stop messing around. You know what I mean. What is this?" Kate waited for him to answer impatiently.

Rick sighed and sat on the edge of the bed. Kate left her covers behind and moved next to him. It didn't matter that she was naked. He had seen everything already.

"Castle… What is this? What are we doing? I understand the sex. I mean, what are we doing?"

"You told me I had no idea. So, I decided to show you that you were wrong. I did have an idea. You seemed to enjoy it." He paused to see what her response, if any, would be.

"Yeah, I did." Kate got up and hugged him from behind. "I enjoyed it. Is this a one-time thing?" She needed to know.

"It doesn't have to be. I enjoyed it too." Rick turned his head to look at her. "We can keep this up if you want."

Kate thought about that. She could say yes, or she could say no. If her answer was no, things would go back to normal. She would be without a lover and didn't know what to think.

"I would like that," she found herself saying. She didn't believe the voice was hers.

"I would like that too, very much." Rick spun in place, taking her into his arms and kissing her. She returned his kisses eagerly.

He brushed his fingers over her cheek. "See you at the Precinct?"

"Yeah." Kate kissed him again and watched him leave. She still didn't believe she had done that. Did it make them lovers?

Kate yawned and went back to bed since it was still early. She tossed and turned a little and then drifted off to sleep.

~oo0oo~

Kate walked with him into the apartment building, though for a change, there was a smile on her face.

"I'm not sure where you're going with this, Castle," Kate said as they got into the elevator.

"It takes 32 seconds to get from the basement to the 12th floor." Rick looked at his watch as the door opened.

Kate leaned against the back of the elevator. "Great, I'll alert the media."

Rick looked at his watch again. "Only the second time, it took her 37 seconds."

He had her attention now. "Why would it take her five extra seconds?"

"Because, the second time, she was on her way to… the 15th floor." The elevator dinged, and the door opened.

"This doesn't make any sense. The Petersons live on the 12th," Kate said. "Castle?" She saw a woman with her little girl leaving and locking the door.

~oo0oo~

Rick confronted Kate. "So, it looks like I made it through the case without being injured, shot, or killed."

"Yeah, well, there's always tomorrow," Kate teased mischievously. "My place tonight?"

"No, my place this time. Bring a bag." Leaning in, Rick gave her a quick kiss, then left to flag down a taxi.

"Your place?" Kate called out after him. She hadn't expected that and wasn't sure she was ready for this at all.

~oo0oo~

She had to go back to the Precinct to find out where Castle lived. Then she went home and went through her closet. Kate took her time, unsure of what to bring and also because she was packing a bag. Like she was going to spend the night at his place.

The taxi pulled over to the curb and a nervous Kate got out. She was outside the building where Castle lived and she looked up. He was up there somewhere. It was a lovely building in the SoHo district. For a moment, she considered getting back into the taxi and going home.

Yet here she was, in the elevator, going up to the top floor. She realized there was just one way to go, so she walked in and ended up in front of a metal door. The fact that it was metal was interesting. There was a door buzzer, so she raised her hand to press it, but she didn't. "Get it together, Kate," she said to herself. She took a deep breath and pressed the buzzer, hearing it buzz.

Kate waited and watched as the door opened. There was a Castle, just not the right Castle. Alexis was standing in the doorway. "Detective Beckett? Is my dad under arrest again?"

Kate shook her head. "No, not this time."

Castle came up behind his daughter and saw who it was. "Beckett! Come in, come in."

"Thanks." Kate stepped past Alexis and Castle and into the loft. She instantly saw the living room with a leather sofa, a dining room with a table for six, and the kitchen with a touch of red, along with an island that had three kitchen island chairs. She stopped and turned to face the Castles.

Alexis didn't understand, but she went with it nonetheless. "I'm helping Dad with dinner if you'd like to join us?"

"Sure." Kate hadn't cooked anything in a while, even if she did know how.

"Here, I'll take that." Rick took her bag from her and carried it into his bedroom. When he returned, he saw Kate and Alexis together in the kitchen.

He decided to sit at the breakfast bar and just watch those two work.

~oo0oo~

At first, she was distant and kept them both at arm's-length, but after a while, she opened up. She was even laughing with Alexis. It was truly remarkable.

"I'm glad you came, Detective. Dad doesn't invite people over to eat. I'm glad he did this time. Now, if you'll excuse me, I'm going to my room. You should come again." Alexis smiled at her and went upstairs. Kate followed every move she made.

Kate looked at Castle. "She's a good kid. You did well with her."

"I wish I could take the credit, but I can't. Alexis has a way of deciding what's best for her by herself. I didn't have anything to do with it. She amazes me."

Kate helped him pick up the dirty dishes and clean up the kitchen. "This side of you is unexpected. I knew you had a daughter and a mother who isn't here right now, but this is different."

Rick grinned at her. "Makes you want me, doesn't it?"

Kate rolled her eyes. "And you had to ruin it."

He stopped smiling. "I don't question how you deal with stress, so let me deal with mine my way."

Kate stared at him. "Your technique is making fun of what people say?"

"It works," he said and kept cleaning up.

~oo0oo~

Later they were sitting on the leather sofa side-by-side, touching and kissing. Lots of kissing. "Castle, what are we doing?"

"We're kissing." The look she gave Rick told him that wasn't what she was asking. "Fine, have it your way.

"Meredith, my first wife and Alexis' mother, is a fruit cake. She's been a fruit cake ever since I met her. Then she ended up pregnant with Alexis. At first, she wanted an abortion. She's an actress, and she said no one would hire a pregnant actress.

"I married her to stop her from getting an abortion. Alexis was still an infant when Meredith cheated on me. I caught her at it, and a few days later, she filed for divorce. She got half of everything; I got Alexis free and clear.

"I married Gina for a different reason. Let's just say it didn't work out, and it cost me two million to end that marriage. You're so unlike either of those two. For one, you're real. And second, you're a cop.

"You told me I had no idea and walked away. That didn't sit well with me, so I took a chance. I had help with finding out where you lived, and I went there. I stood outside for half an hour debating with myself whether this was a good idea.

"Was it? …A good idea?" Rick asked her. Because if she said no, then he was dead in the water.

Kate looked at him and let him suffer for a time by being silent. Eventually, she put him out of his misery. "Yes, it was a good idea. This isn't a one-time thing, is it? Because I'm not looking for a one-night stand."

"Considering we've had sex twice now, I'm pretty sure it's not a one-night stand." Rick saw the look on her face. "No, Kate, it's not. I want it to last if you can put up with me."

"Could you try acting more like a grown-up, please, and less like a child?" Kate asked hesitantly. "The nine-year-old on a sugar rush is tough to take."

"I promise, I'll do my best." Rick kissed her. They continued kissing until Kate had had enough. She got to her feet and pulled him along with her, heading for what she took to be a bedroom.

She walked into a bedroom and saw that it was smaller than she thought it would be. Still, she started taking off her clothes while watching Rick take off his.

They returned to kissing but soon that changed to touching. And finally, they made love.

~oo0oo~

Kate was awake and looked at the time. She still had plenty of time, enough for another round of lovemaking. She got up on her knees, took him in her hand, and at last, her mouth.

Rick woke up to her giving him a blow job. He ran his fingers through her hair to tell her he was awake.

Kate got up and sat on him since she hadn't finished him off quite yet. She raised and lowered herself on him, fucking him. It was their fourth time doing that.

~oo0oo~

Kate was in the shower, his shower. She was enjoying having the extra space when Rick joined her. He washed her from head to toe. It was a feeling Kate had never had before. None of her previous lovers had ever done that. She loved it! She stopped him before he left the shower by kissing him.

A short time later, Kate was sitting in the kitchen enjoying her first cup of coffee when the front door suddenly opened, and in walked Martha.

"Katherine. What a pleasant surprise." Martha came straight to her. "You're glowing. I know that glow."

"Martha, I… "

"I don't need to know what happened between you and Richard. It's none of my business. However, I whole heartily approve." Martha patted her hand. "I'm going up to my room. Try not to be an absent person, dear. We all approve of you being here." Martha left her and went upstairs to her room.

Kate was sitting there in stunned silence when Alexis started down the stairs. "Detective, you're still here." Alexis walked the rest of the way down the stairs and went into the kitchen, looking for something to eat before school.

"Alexis…" The redhead raised a hand to stop her.

"I don't need to know what you and Dad did. But I approve." Alexis found a bagel, sliced it, and spread cream cheese on it. Then she got ready to leave. "You're always welcome here, Detective," Alexis told her as she picked up her backpack and jacket.

"You can call me Kate."

"I'll think about it," Alexis teased, leaving a dumbfounded Kate in her wake.

Kate had finished her coffee and was ready to leave. Rick still hadn't come out of his bedroom, so she waited. When he did, he made a beeline for the kitchen and the coffee maker.

"Your mother came home."

"Oh?"

"And Alexis came downstairs; she's gone now."

"Sounds like you met my whole family this morning."

"Yeah, I did. They welcomed me." Kate was still surprised at that.

Rick smiled at her. "Of course they did. I have something to do, so I'll be in the Precinct later. You can leave your bag here. I'll wash what's in it later."

"Okay." Kate wondered what he was up to but didn't say anything out loud. "Oh, before I forget, do not tell Montgomery anything about us. There's a regulation preventing workers from being together. I'll be reprimanded and maybe even…"

"Alright, tell Captain Montgomery nothing. Got it." Rick kissed her, and she kissed him back.

Kate left him but looked behind her, not really believing Castle when he said he'd tell Montgomery nothing.

~oo0oo~

Rick was in later after the case was closed and walked straight to Montgomery's office.

Kate arrived and saw Castle was already there, sitting in his chair next to her desk. "Hi." She sat down. "We solved the case. It was Chloe, the other nanny. They were sharing the same…" Kate saw the look on his face. "What?"

"I have something for you." He opened his hand and showed it to her. It was a little black box.

Kate immediately thought it held an engagement ring, but she wasn't ready for that, not yet. They hadn't even gone out on a date. They had made love but not on a date. She was doing this backwards.

Rick smiled and gave it to her. "Open it, Kate."

She didn't open it at first, but she swallowed hard and did. It was a ring, but not an engagement ring. It didn't have a diamond. It had a series of little blue gems all the way around the band. It was lovely, but she didn't understand its meaning. Kate looked at him for an explanation.

"It's a promise ring. A promise ring symbolizes one partner's devotion to the relationship, and accepting it does so for the recipient. It's a promise as more of a symbol of devotion to one another.

"It means I promise not to cheat on you, ever," Rick told her.

Kate thought it was sweet, and she took out the ring and looked at it. "Which finger does it go on?"

"It goes on your ring finger. On the left hand if you're not married, and on the right hand if you are. The reason they're typically worn on the ring finger of the left hand comes from the ancient superstition, one that's unfortunately not anatomically correct, that there's a vein that runs directly from that finger to the heart. But you can wear it on any finger you choose. Even your pinky finger it you like."

Kate thought about it and slipped it on the ring finger of her left hand. "Thank you. I wish I could kiss you right now."

"About that. I talked to Roy…" Just then, Rick was interrupted.

It was Montgomery. "Beckett, Castle, my office." They both entered his office, and he told them to close the door and sit down. "Castle tells me you two are romantically involved," Roy said. Kate gave Castle her best I'm going to kill you look. She had trusted him not to tell Roy anything.

"I have no objection provided you keep the PDA down, and by down, I mean non-existent. If I find out that the two of you so much as step a foot the janitor's closet, I'll suspend the both of you. Do I make myself clear?"

"Yes, sir. You do, sir," Kate replied. "Castle?"

"Well, I can, but I don't know that she can," Rick said.

"Castle!" Kate glared daggers at him. She was going to kill him this time. Really kill him.

"Now that that's over with, I'm happy for both of you. You deserve each other." Roy glanced at the clock. "Now get out of my office and get back to work." They both got up and left.

"You talked to Montgomery after I told you not to?" Kate hissed.

"Technically, I don't work here. I'm not a cop, so the regulation shouldn't apply to me." Rick shrugged. "So yes, I talked to Montgomery. He told me it wasn't a problem. The no PDA was new, but he told me everything else."

Kate sat there and thought about that. It worked, so she couldn't be that mad at him. Still… "If you do something like that again, so help me, I will make you suffer. You hear me?"

"Loud and clear. You still like your ring?"

She looked at her new ring. "Yes, I do. Thank you. But don't get any ideas about turning it into an engagement ring."

"I promise. If I turn it into an engagement ring, the first to know will be your father."

Kate blinked. "My dad? Why my dad?"

"To get his approval first," Rick explained patiently. "I'm old-fashioned that way."

Hearing him say that, Kate smiled. "Come on, Castle, I feel like being outside the Precinct so I can kiss you."
