A/N: Sorry guys. I had to rewrite the love scene like 12 times to get it as perfect as I could. It seemed important. And since I write out of order, that means everything was done but that. .

Private Note: Happy Birthday, Bunneh. I love you.

Rick watched Kate unbutton her shirt as he did the same with his own. There was something... exciting .. and incredibly erotic about watching her undress; even though she had done it so many times that he was amazed it was still so powerful... normally.

But this time...

This time...

It was different.

He stopped undoing his own buttons, watching with a small smile as she slid her bra off. Reaching down, he splayed his hand across her belly. "There's a little bit of me... inside of you right now..." He whispered.

Kate faltered; her breath becoming harsh as she tried to think of something to say. "There's... been a little bit of you inside of me for a couple of months now, Castle."

"A little bit?!" He looked offended.

"Okay..." The detective said with a rueful grin. "Maybe not so little."

"Thank you." Rick threw his shirt across the room; toeing off his shoes and socks but only reaching for his waist when Beckett did the same. He was down to his boxers in no time flat, looking at Kate in confusion when she was still behind the curve.

She looked pointedly at the large red S on the fly of his blue boxer briefs. "Brag much?" One eyebrow arched. "So... No loincloth, huh?"

Castle grinned. "It's in the wash."

Kate shook her head, knowing the saddest part was that he was probably serious.

She reached out and stuck a finger under his waistband; pulling it out as far as she could before letting it fly back with a loud 'snap'.

"Hey!"

"Then get rid of them."

The writer did as he was told; stopping to look at her pointedly when she didn't move.

"What?" Beckett grinned at him broadly, crossing her arms behind her head. "You think these heels are going to take themselves off?"

Castle scowled at her. "I'm pretty sure Tarzan never took off Jane's boots."

"Well... We can play with the roles a little bit."

He smiled.

She was so lucky she was Beckett.

Castle nodded, grabbing one boot and pulling it gently free before following it with the other. When he removed her hose, he scratched his nails down her calves; feeling the tremors in his own spine matching hers.

"Tell me you're mine." Rick shook his head when Kate's eyes darkened. "Not like that. Not in a possession kind of way. I don't want to own you. No one should ever, or COULD... ever, own you. I just want... I need to know that..." He closed his eyes. "Just tell me... Please."

There was no hesitation.

"I'm yours."

Castle grabbed her jeans, pulling them and her whisper-of-lace panties off before quickly settling between her thighs. When he suddenly froze, Kate looked up at him in concern, only to swallow heavily when she saw the look in his eyes. "I..." His mouth kept working but no sound came out.

She took pity on him; smiling in spite of herself. "We're losing the mood here, caveman."

"No..." Castle slid on top of her, digging his fingers into her hair; winding it around his hands as he pulled her lips up to his. His tongue forced itself into her mouth, unable to control his smile when she opened wider to let him in. "Never."

The heat coming off the writer's body was intense; the feel of him, incredible. She felt the soft whisper of his over-heated skin brushing against her and surged into him. "Rick..."

Kate's voice was ragged and it tore through him like a knife, sending his heart racing as he kissed his way across her jaw and down her neck. When he reached the pulse jumping in her throat, he bit down hard, making her hiss.

But he didn't apologize.

Instead he sucked harder, groaning when her hips pushed up against him, making him squeeze his eyes shut to keep from thrusting himself into her.

"Castle..."

He shook his head, grabbing her hair and pulling her backward, making Kate arch her neck so he could trail his lips across it.

"Word?" Rick whispered.

Beckett grinned under his touch, lost in the feel of his mouth. "Trust me... Castle..." She gasped. "You'll know it when you hear it... If you ever do."

The writer actually stopped breathing for a moment.

Then he slid his way lower, running his fingers along her ribs; reveling in the shudders that wracked her body. He licked the skin between her breasts, thinking it was the softest, sweetest taste he had ever known...

Except maybe for one other.

But that was Kate too.

This... this was the salt-sweet tang of the sweat that lightly coated her skin, mixing with his own; creating a scent that was uniquely their own.

Castle nibbled and kissed his way down her abdomen; slowing when he reached her belly, tracing the outline of her abs with his fingertips.

"Kiss those goodbye." Kate smiled, running her fingers through his hair, adoring the weight of him on top of her.

"I'll kiss every inch of you for the rest of my life."

Becket felt the weight of his words, felt how much he meant them.

He wasn't a man-child anymore.

He was whole now.

And so was she.

Kate closed her eyes as he continued downward; burying his nose between her thighs and inhaling deeply.

Castle smiled, loving the feel of her tightly trimmed hair against his cheeks and chin, the scent of her; so clean and heady. He flicked his tongue out slowly; teasing her mercilessly, increasing the pressure against her swollen bundle of nerves as she writhed beneath him.

"Rick..." Her fingers tightened painfully in his hair as he slid his hand up her thigh, groaning into her; his breath hot against her sensitive flesh as he realized the slickness had traveled halfway down her thighs.

"Jesus..." The writer closed his eyes, trying to control the lust that shot through him.

But Kate wasn't having it. She reached down and took hold of his hand, pulling it up to impale himself on two of his fingers with a shallow gasp. "Yes..."

That was all Rick needed. He wrapped his left arm around her waist, pulling her hips up roughly to gain better access with his mouth even as his fingers curled deeply inside of her.

He wasn't quiet. It wasn't reverent.

It was wild, and hot... and everything he knew they would be together.

And more than he had ever hoped for.

He felt Kate start to clench around him and increased the pressure of his fingers and his tongue.

When she shattered, it was hard and fast; almost dirty. Vulgar words falling from her lips and making him bury his head in her stomach to control himself.

Her body vibrated for several long minutes; small quakes shuddering through her, making her tremble beneath him. When he felt her hands in his hair, he took a deep breath.

"I can wait." He whispered slowly, trying to regulate his breathing.

Beckett tugged him up roughly, pulling on his hair until she was staring directly into his eyes; her pupils so wide with desire there was no color left.

"Don't you fucking dare." She took hold of him, guiding him into her as she locked her ankles behind his ass; tugging him forward.

Rick slid into her with something so close to relief that it actually scared him for a moment.

She was his home.

It had taken him forty plus years but he finally understood all those old love songs.

Then Kate tightened her calves, making him grunt as his body took over, shutting down his brain as he lost himself in the feel of the woman beneath him.

Kate stumbled out of the bedroom, yawning as she fumbled with the buttons on Castle's shirt. She had grabbed it and his Superman briefs up off the floor as she headed for the kitchen, in desperate need of water. Castle had run back to the fridge after round... one... ish; bringing six bottles back to bed with him; lining them up on the nightstand like little soldiers.

And one by one... they had fallen.

War was hell.

She ran her fingers through her hair, reaching for the fridge to pull a bottle out eagerly. She drained half of it, her head tilted towards the ceiling as she shuffled back the way she had come.

"Hey."

Beckett snorted in surprise, water spraying out of her mouth as she blinked at the young redhead on the couch. Dropping the bottle onto the living room table, she grabbed the bottom of her borrowed shirt, trying to pull it lower as she bent her knees. "Alexis." She wiped her mouth, smiling. "Sorry, you scared me."

"That's okay." Alexis threw her a pointed look. "I've seen worse. And I scare myself sometimes."

Kate saw the moonlight glinting off her own finger and quickly covered the ring with her other hand. She wasn't worried about the girl's reaction, but she was pretty sure Castle would want to tell her himself. She looked at Alexis carefully. "Is this about Tabrett? Do you want me to wake up your dad-"

"No!" The younger woman swallowed, whispering, "No. It's just... I have no idea what I'm doing."

The detective sighed, leaning against the counter. "I don't think you're supposed to, sweetheart."

"I just... I don't understand...

"What?" Kate's voice was gentle. "What don't you understand? Or better yet, tell me what you DO understand. She's smart?"

"And funny."

"She makes you laugh." Kate crinkled her nose, rolling her eyes. "You'd be amazed what that's worth." She moved a few steps closer. "She's interesting and exciting. Foreign? Different."

Alexis swallowed, nodding.

"Different matters too." The detective took a deep breath. "The most important thing, Alexis, is that you only do what you are ready for. Just because you're capable of... appreciating Tab's qualities, doesn't mean that you should act on it."

"So you're saying I shouldn't?"

"No!" The detective shook her head adamantly. "Not anymore than I am telling you that you should. I can't tell you what to do. No one can. But I can tell you... You only have one first time. And I'm pretty sure that's what we're talking about here. It will stay with you for the rest of your life. So just... be sure."

"Have you..." Alexis paused, looking at the detective pointedly.

Kate blushed. "No." She ran her hands through her hair, going to sit down next to the young redhead. "There was... One girl... One time. I was about your age."

Little Castle looked like she was battling between being polite and being curious.

"You can ask me anything you want, Alexis."

"Did you... do... anything?"

Beckett laughed softly, shaking her head. "A kiss. Nothing else. I wasn't quite to your level of maturity at the same age." Her eyes turned distant, lost in memories. "But I still think about her sometimes."

"Do you think you were... are... you know..."

"Bisexual? No." She shook her head. "It just wasn't me. Not that I would have minded. Would have made for a lot more interesting Saturday nights." She grinned at the younger woman's wan smile. "I still believe it would have been lovely. Alexis, there is nothing wrong with being who you are; as long as it is honestly who you are. And how do you think you figure that out, without answering your own questions?" Alexis shook her head and Kate wrapped her arms around her. "What I told you before is true. You can't base who you are going to be on who you've always been. The best advice I can give you, is be true to yourself, and be careful."

Little Castle looked at her, an honest smile on her face. "Thanks', Detec- I mean Kate."

"You're very welcome. Always." She hugged her again and then stood. "I better get back..."

"Before he sends out a search party."

Kate had almost walked through the bedroom door when she heard Alexis whisper, "Welcome to my family, Katherine Beckett."

Castle wiped his eyes tiredly before tying his robe shut. He had managed to steal his boxers back from Beckett for the moment, but something told him it would only be a temporary victory.

She loved to wear his clothes.

And honestly... he loved it too.

"Richard?"

Castle jumped, squeaking softly in surprise. He stared at the woman on the stairs before sighing. "Yes, Mother?"

"I was just wondering why you were standing in the middle of the living room with your eyes closed." Martha descended, following him into the kitchen; her eyes sharp as she watched his every move.

"Was I?" He shrugged. "I was... thinking. What are you doing home? I thought you were staying uptown until the play ended."

The older woman ignored the question. "What were you thinking...about?" She waved her hands dramatically, making Castle blink.

"A... story." He frowned at her, opening up all the wrong cabinets as he looked for his french press.

"Are you sure?" Martha looked at him pointedly.

"Of course I'm sure, why wouldn't I be sure?"

"Well..." The actress sat down on one of the barstools, pulling something out of her pocket with flourish. "There is this."

Rick stared at the small velvet box in her hand.

"Where... how? When?"

Martha shook her head. "I found it on the floor. And trust me, while that was surprising, it was even more surprising..." She flipped the box open. "When I found it empty."

The writer looked at her like a deer in headlights.

"Oh for goodness sake, Richard. Just tell me she said yes!"

"She said yes."

Martha smiled broadly, coming around to hug her son.

"Don't get me wrong, I am ecstatic that you're happy for us, Mother. But how did you even know to be here?"

The redhead shrugged. "A mother knows these things."

"Huh." He shook his head, finally finding the coffee pot. He smiled sweetly at his mother, yawning and shifting slightly as his back cracked.

"Hmm... maybe she is too young for you."

"Mother," Castle closed his eyes tightly. "Please do not ever comment, even vaguely, on our sex life."

"Hey , Dad."

Castle jumped, almost dropping the french press he was holding. "Hey... hey, pumpkin. Uhm... where's Tabrett?"

Alexis looked around her. "Dad? It's seven in the morning. Why would Tab be here?"

"Right..." He flushed. "I uhm... I... Sometimes I forget that you're seventeen."

"Ah, well... I don't."

He came around the counter and wrapped her up in a hug. "Something I am grateful for every single day."

The red head's eyes narrowed. "Are you okay?"

"Yeah! Of course. Why... why wouldn't I... Yeah, I'm great." Castle swallowed. "Why, uhm... what do you... I'm good. Why?

"Because you only stammer when you're nervous?

"Nervous. Pffft. No... not me. Not nervous. At all."

"Dad..."

"It's my fault, Alexis."

The young woman glanced over her shoulder. "Explain, please?"

Kate tied her robe around her waist as she walked out of the bedroom. "I think I may have ... broken him..."

"Is this about the ring?"

Beckett blinked.

Even Martha looked surprised.

"I saw it last night." The redhead crossed her arms. "I'm not blind. I just... didn't think it was the time to ask."

"Right." The detective nodded.

Alexis looked back and forth between her father and Kate. "But now seems good." Her eyebrows arched.

"Uh..." Castle looked at Kate hopefully but the detective just shrugged. "Well... You know that Kate and I... me and Kate... have been-"

"Dad!" Alexis held up one hand. "Let's fast forward? I know you've been together, I know you asked and she obviously said yes. I don't need the gory details. I guess I just need to know... why now?"

Rick looked at his daughter in confusion. "What do you mean?"

"Isn't it... Kind of sudden?"

"Well..." He began to stammer again. "It's not... if you count the last three years as... you know... courting. Not... quite so sudden."

Alexis looked at her father; seeing the rim of panic in his eyes, tempered only by the love she saw for Kate. Then she stared at Kate, seeing what she had missed in the midst of her own realities.

"Oh my god!" She whispered. "How long?"

Kate held her head up. "About 6 or 7 weeks." She loved Castle. This child would be their future; a future she wanted. It didn't matter how she got pregnant. Only that she was.

Kate's brow furrowed as she frowned.

Damn.

Even his freaking sperm was persistent.

"So..." Alexis took a few steps backwards. "I'm going to be... a big sister? Now? I'm seventeen!"

Castle walked towards her, trying to hide his hurt when she shrugged off his hand. "Pumpkin, this wasn't planned. It just kind of... happened." He looked at Kate, unable to hide the smile that lit up his face. "But, it's a good thing. A really good thing. I think if you just give yourself some time..."

"Time?" The young woman's voice was sarcastic. "Well you haven't really given me that option have you?"

Beckett took a step closer. "Alexis-"

"No, Kate... Detective." Alexis pressed her lips together. "Look, I'm not angry... with either of you. But this is... well, big doesn't even cover it. And I think Dad is right. I need some time. To process."

They both nodded. Watching as she walked up the stairs.

"Wow." Kate crossed her arms, dropping her chin to stare at the floor. "Poor kid. She's had a lot to deal with over the past few weeks."

"More than you two?" Martha looked at them curiously.

"What, the motherly 'spidey-sense' doesn't transfer to grandchildren?" Rick smiled gently. "Let's have some coffee. You're probably going to need it."

"Forget the coffee," The matriarch went to the wine fridge. "From the look on your face? I'm going to need something a little stronger."

I'd freak too!

Please review if you have time! Thanks to all that have!
