A/N: A new storyline for McRoll. It's just a small story. I wanted to make it a one shot first but then decided to put it in a few chapters. Hope you guys like it. The story is set after the season 5 finale.

I do not own Hawaii five-0 or any of the characters.

Kono and Adam's wedding was very beautiful. Catherine was glad that she had come back to Hawaii to see this and that everything had turned out okay after finding the nuke. She was so glad that Steve was okay. There had not been a day that she didn't think about him in the past year. She was glad that she had made the decision to go back to Hawaii. This is where she belonged. She just hoped she and Steve could sort of pick up where they had left of. They didn't really have the chance to talk today, work kept coming in between. Maybe they would have a chance to talk after Kono's wedding. Catherine did have to admit, Steve looked very handsome in that suit. If that call hadn't come between them she probably would have kissed him and make him not want to go to the wedding anymore. Catherine hadn't realized how hard it had been to be away from Steve until she saw him again. She had missed him so much and so couldn't want to feel his lips of hers again and his strong arms around her and his…

"Snap out of it Catherine," Catherine told herself since they were still at the wedding ceremony. But the truth was she couldn't wait to be alone with Steve.

Once the ceremony was over Kono and Adam walked down the aisle while the people threw rose petals over them. They really looked like a beautiful couple. Kono and Adam went to take some pictures as the guests made their way over to the party area. When Kono and Adam returned it was time to catch the bouquet. Catherine wasn't really trying to catch it but the bouquet landed in her hands.

"I see you caught the bouquet," Steve spoke when Catherine walked back up to him.

"Yeah, I sorta did," Catherine replied, looking at the bouquet in her hands. It felt a bit weird standing there with a bouquet in her hands.

"Nice catch Cath. Maybe next time, it'll be you throwing the bouquet," Kono spoke, appearing behind them.

"Maybe."

Catherine and Steve had a great time together at the party. It was about 1am when they left.

"You don't mind me staying here, do you?" Catherine asked as they walked into Steve's place.

"Of course not."

"Okay good."

"I'm really glad you're back again Cath."

"Me too. But you do understand why I had to go right?"

"Of course I did." Steve pulled Catherine to him. "But I would be lying if I told you I hadn't missed you."

"I've missed you too Steve."

"I love you Catherine."

Catherine looked at Steve. He had said those words to her over the phone about a year ago and now he had said them face to face. Face to face was way better, Catherine could see the love in his eyes.

"I love you too Steve."

Steve pulled her ever closer and crashed his lips down on hers. God if felt so good to kiss her again. Steve planted his hands underneath her ass and lifted her up. Catherine automatically wrapped her legs around his waist as Steve walked them upstairs. Steve was taking her upstairs to the bedroom, the bedroom that they had spent a lot of glorious nights in before. Steve gently put her down on the bed and lay down on top of her, without breaking the contact with their lips. Her lips just felt so perfect against his. Steve reached behind her and until the zipper of her dress. He pulled the straps down, kissing the newly exposed skin.

"Steve," Catherine moaned as Steve kissed the spot in her neck.

"I love you Cath," Steve whispered in her ear.

"I love you too Steve."

Steve took his time in undressing Catherine and showing her how much he had missed her and how much he loved her. Steve knew he was teasing her but he was savoring every moment. It had been way too long since he had made love to Catherine. It seemed like to take forever to Catherine before Steve finally pushed himself inside of her. It felt so damn perfect, just like she remembered it. The only sounds that could be heard were their moans and groans and the sound of two people moving together. Catherine clung to Steve as she reached her high point.

"Wow, that was great," Catherine uttered as Steve collapsed down on her.

"Oh yes, it totally was. God I've missed this so much," Steve spoke as he rolled off of Catherine.

"Yeah I've missed this too," Catherine said as she rolled over on her side, facing Steve. "It's good to be back again."

"So how long are you staying?"

"How long do you want me to stay?"

"If it were up to me, I would never ever let you go again. I've missed you terribly over the last year. I never ever want you to go again. I want you in my life, forever."

Catherine smiled at him, that smile did so much to him. "I never ever wanna go again either. This is my home, here with you."

"I'm glad you said that, cus I have something for you. I bought this just after you left for when you would come back. Close your eyes."

Catherine closed her eyes and heard Steve rumbling in his nightstand. She felt him leave the bed. She wondered what he was doing when she felt his hand on the other side of her, pulling her into a seating position.

"Open your eyes Cath."

Catherine opened her eyes and was surprised to what she saw. Steve was sitting on one knee in front of her with an open jewel box in his hands. In the box was the most beautiful ring Catherine had ever seen.

"Oh my god Steve."

"Catherine Rollins, will you marry me?"

"Yes, of course I will Steve."

Smiling Steve placed the ring around Catherine's finger. He put the box on the nightstand and kissed Catherine deeply as he pushed her down onto the bed. Before they knew it they were making love again. Shortly after that they fell asleep.

A few hours later Catherine shook up.

"Cath?" Steve asked half asleep. "Everything okay?"

"Yeah, it's fine. Go back to sleep Steve."

Catherine lay back down on the bed but she couldn't stop the tears from flowing.

"Cath? What's wrong?" Steve asked concerned, fully awake now.

"Steve, there's something I have to tell you."

"What's wrong Cath?" Steve could tell that something was really bothering Catherine and that she had a hard time telling him. "You can tell me anything."

Catherine took a deep breath before speaking. "A few weeks after I decided to stay in Afghanistan I…. I…"

"What is it Cath? Did something bad happen to you? Did someone hurt you?"

"A few weeks after I decided to stay in Afghanistan I found out I was pregnant," Catherine quickly spoke.

Steve's face froze. Catherine was pregnant! But it had been a year ago since she had gone to Afghanistan. If she had been pregnant where was the baby? Had she lost the baby? Why was he only just hearing this now?

"You were pregnant?! With my baby?" Steve finally spoke after a few minutes of silence.

"Yes I was. Yes of course it's your baby."

"It's? Not was? You didn't lose the baby?"

"No, I didn't Steve. Steve, we have a three month old little girl."
