A/N: I do not own any of this.

Thank you soooo much for all the reviews, alerts and favorites. Each and everyone make my day. This one was a pain. But I felt like I couldn't skip over their wedding...

...

It was an unseasonably warm October Saturday. The sun was shining and the sky was a cloudless blue. Kate Beckett couldn't have asked for a more perfect day for her wedding. She was marrying Richard Castle today. Holy crap. She took a deep breath as she looked at herself in the full length mirror.

She chose a strapless flowing ivory gown, perfect for their small beach ceremony at Castle's Hampton's house. The dress fit comfortably over her growing stomach but at seven months there was no hiding that she was pregnant. Not that she wanted to hide it. But as she put on her dress an hour ago she realized that someday her kid was going to see the photographs from today and know that he was conceived out of wedlock. She knew it didn't matter but imagining the conversation made her cringe. She took a deep breath and decided she'd make Castle explain it. This whole pregnancy was his fault to begin with and he's better with words. She smiled as she thought about Castle fielding awkward questions from a curious six year old. A soft knock at the door pulled her from her daydream.

"Go away Castle," she admonished. He'd been trying to break the rules and see her all morning. She heard a quiet chuckle through the door before her dad appeared, his hands in the air.

"It's just me Katie."

"Hi Dad," she smiled at him.

"Wow, you look so beautiful," he said pulling her into a tight embrace.

"Thank you Dad."

"What were you thinking so hard about?" He asked. She absentmindedly touched her belly. She sighed heavily.

"The kid," she couldn't help the smile that blossomed on her face. Only two months left until he...or she would be here. Castle had wanted to find out the sex but Kate wanted to hold off. Rick was so sure it was going to be a boy, to the point of annoyance, that she thought he could stand to wait a little longer to find out if he was right or not. "I honestly never thought I'd be pregnant on my wedding day," she almost whispered. Jim Beckett surveyed his daughter for a moment then took a deep breath.

"Your mom and I promised each other we'd never tell you this, but..." Kate immediately perked up at the tease of some new little piece of her mom. "I think under the circumstances she wouldn't mind." He looked nervous.

"What?" Kate pleaded. "What is it?"

"About two weeks before our wedding we found out your mom was pregnant with you," he smiled shyly at her. Kate's eyes were wide in shock before a laugh escaped.

"Seriously?" she asked. He nodded. "Wow, that actually does makes me feel better."

"Good. It worked out for us because everyone just assumed you were a honeymoon baby."

"Ew." She said, not really wanting to think about her parents like that. Jim smiled knowingly and dropped it.

"Your mom would be so proud of you Katie." Kate's throat tightened along with her chest. Her eyes began to sting.

"Dad, you can't make me cry. My makeup has already been done," she admonished.

"I'm sorry, but she would be. And she'd love Rick," he said.

"Yeah?"

"Definitely," he promised.

"I love you," she said hugging him hard.

"Love you too." He said kissing her cheek. "It's show time."

...

They swayed to the soft music as their friends and family watched.

"I'm glad we didn't wait," Kate murmured against his neck.

"Me too," he whispered. "Although, how cute would he have looked in a little baby tux?" He asked dropping a hand down to caress her bump receiving a kick from the baby. "See he agrees!"

"Maybe she is sick of you calling her he." She said leaning back to see her husband's face. He contemplated this for a moment.

"Nope. That's not it," he said with a teasing grin. "He wishes he was on the outside for the party." Kate laughed as he pulled her closer to him. "Thank you," he said softy against her hair.

"For what?"

"Marrying me," he said simply. She reached up onto her tiptoes pressing her lips to his.

"Anytime," she mumbled against his lips.

...

They made their way back into the house around 11 while the party continued outside. Kate was exhausted and her feet hurt. As they reached the back door off the deck Rick swept Kate up into his arms.

"Castle," she groaned. "Put me down."

"It's tradition babe, let me have this." He begged.

"Fine," she huffed tightening her arms around his neck. "Caveman," she mumbled. She saw his mouth twitch in amusement. He carried her all the way into their bedroom, dropping her carefully on the bed. She shook her head at him, her mouth twisted in a small smile. He dropped a kiss to her lips and then one on her swollen abdomen.

"Although you look absolutely gorgeous and perfect in this dress I'd really like to take it off you now please." He murmured as he hovered over her.

"Is that right Mr. Castle?"

"Mmmhmm, Mrs. Castle," he breathed. Her stomach flipped pleasantly at the new moniker. She'd always be Detective Beckett, but outside of work she was very happy to be a Castle. She raised up onto her elbows searching for his lips. She found them quickly and pulled him into a heated kiss as Rick's hands searched for the zipper. She lifted her hips to aide in the removal of her gown. He carefully laid it over a chair in the corner of the room before stripping down to his boxers. Kate laughed out loud when she saw his backside. Printed across the ass of his underwear was "Mr. Kate Beckett." He grinned widely at her and wiggled his hips for her. "You like?"

"Yes, I do. Where did you get those?" She asked wiping tears from her cheeks.

"Ryan and Esposito. Although I think it was Lanie's idea." He said as he crawled up the bed toward her. He stretched out along her side laying his head next to hers on her pillow. "Hi." he whispered. Kate turned her head towards him so that their noses were touching.

"Hi," she said smiling at him. He looked back at her in awe. It was almost as if he couldn't believe he was there with her. She almost couldn't believe it either. She was married to Richard Castle. He was her husband. She couldn't get over how incredibly right it all felt. Almost as if he could read her thoughts he brought a palm to her belly.

"I love you," he said as sincerity spilled from his beautiful blue eyes. She felt a tightness in her chest as she swallowed the lump forming in her throat.

"I love you too," before she started crying she added, "So are we going to consummate this thing or what?" His answering laugh had the effect she'd desired. With a growl he captured her mouth in a searing kiss.
