Ok, so... fist of all, hey. This is my first story in English. I hope I did good. English is not my first language, so patience, please ;) And if you find any mistakes, please let me know, I will change it as soon as possible ;) But I hope there aren't any.

This idea just popped into my head one day, and I thought it would be great to get it out on the paper, I hope this chapter is good enough to keep reading ;) There will be a twist of course, but not that kind of twist you all think of. You'll see. Anyway, I hope it's interesting enough.

Disclaimer: If I owned them I wouldn't live in Poland.


"Castle? What are you doing here?" Kate asked, surprised by seeing him sliding slowly to her current one-night bedroom."You're not supposed to be here!"

"Oh, come on mrs. Castle, really?" he whined like a little kid.

"May I remind you that I'm not mrs. Castle just yet? And it's a long way till tomorrow, I can change my mind, you know." she said teasingly, as he came closer to her and put his hands on her waist. He pulled her closer and just before kissing her he whispered to her mouth "You'd never do that," and then he pressed his lips to hers. After a moment she broke the kiss, and put her head on his shoulder.

"You're right" she said, breathing into his chest "I wouldn't do that. I love you and I want to be with you. Forever."

That night she was staying at Lanie's apartment, it was a day before their wedding, and she wasn't suppose to sleep/be with her soon-to-be husband right before the ceremony (according to the tradition), and Lanie insisted she stayed at her place. And now he was there anyway. What should she do? Kick him out or let him stay? She didn't want to kick him out. So she quickly came up with a plan.

"Ok, mr. Castle. You can stay here tonight. But no. No funny business and you need to set your alarm clock the earliest that possible. I don't want Lanie to see you, she will be all over my head when that happens." She said, still hugging him.

"I can live with that. As long as you're mine tonight. Sorry, but funny business involved." he grinned, and laid them down on the bed. Kate was sure that she will not get all that much sleep as she planned.

.

The alarm clock rang. 5.30 a.m. Rick rubbed his eyes unconsciously, wondering why it was so early. And then he remembered that his wedding was in a few hours, and he was not supposed to be where he was. Kate was still sleeping next to him, her back pressed to his stomach.

"Hey gorgeous." He whispered to her ear and pressed a soft kiss to her cheek. She felt his breath near her ear, and opened her eyes.

"Hey handsome." She replied. "You know, I don't want you to go." She said softly.

"Well, I can stay. And we can go for the fourth round." He teased, softly biting her ear, and then he started placing kisses on her neck. It felt really good, she thought. Oh, she so wanted him to stay. But with the last remains of her strong will she managed to stop herself from a little moan that was coming up, and sat up against the headboard.

"Rick, we really can't. You need to go." Kate kissed him in the cheek one more time and pulled off the covers, got up in search of her panties and bra. After a couple of seconds when she finally found them she also found Rick staring at her.

"You know, staring is still creepy, Castle." She said and then threw him his boxers. "Go, dress up." Rick did as she said, he went to the bathroom, took a quick shower and then dressed up. He was ready to leave the bathroom, when he heard voices. Two of them. Lanie must have woke up early, too. Jeez, this woman. He waited a little, and when he thought she was gone, he quietly sneaked out of the bathroom. And did he look surprised when he saw his fiancee's best friend standing in the doorway.

"And good morning to you, too." Lanie said. "You know, your facial expression when you saw me was priceless. I don't want to know what happened. In fact, I can figure it out myself, so let me just go and forget those images I just envisioned. Uh..." And she left the room shaking her head.

"Ok, what exactly was that?" Castle asked a little surprised. "She didn't give you a lecture about sleeping with me the night before the wedding?"

"Well, she might have said something, but then she said she somehow knew you wouldn't give up, so she supposed you will be here." Kate replied, coming closer to him and closing them in a warm hug.

"I like her thinking mechanisms, then." Castle grinned and placed a kiss on Kate's head.

(.)

"I, Katherine Beckett, take you, Richard Castle, for my lawful husband, to have and to hold, from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, until death do us part."

"I, Richard Castle, take you, Katherine Beckett, for my lawful wife, to have and to hold, from this day forward, for better, for worse, for richer, for poorer, in sickness and in health, until death do us part."

"You have declared your consent before the Church. May the Lord in his goodness strengthen your consent and fill you both with his blessings. That God has joined, men must not divide. Amen." the priest said. "Mr. Castle, you may kiss your bride." He added.

Nobody had to say it to Castle twice. He went for it right away. The kiss was soft. And kind of hot. And filled with love.

"We're married." She whispered as they broke apart. A huge smile on her face. She was happy. She was going to spend her forever with the man she loved. Her one and done. She was going to have kids with him, and amazing life, grow old together, and tell their grandchildren stories of how they met, how they solved cases together, how they were saving each other's lives. All that was in front of them, and she could see their future so clearly. She wasn't scared of it, she was happy, because she married her second half, and she was sure it was forever.
