[Authors Note: This story just popped into my head so I decided to go with it. This was originally going to be an AU Steve/Kono one shot, but I had so much to work with that it ended up turning into a multiple chapter fic instead. Make sure you Review to let me know your thoughts on the story. If there aren't enough readers why should I keep updating and wasting my time? I do not own any rights to the show or the characters and this fic was not beta'd. Hope you enjoy it. Rated M for love scenes.]

Summary: Steve returns to Hawaii after being away on a highly classified mission for four years. Now that he's back, will Kono allow her prior feelings for him to interfere with her marriage?

Kono sat at her desk attempting to accomplish some paperwork that she had been putting off for a while and since work was slow that day she figured it would be best to get it out the way. Lost in her work, she hadn't realized that Danny came back from lunch and stood outside her office having a conversation with Chin by the computer. It wasn't until she heard Danny's voice vaguely mention a name that made her pay attention to their conversation. McGarrett. She hadn't heard that name in a while and she wondered why she was hearing it in that moment or if she had misheard him.

Kono got up from her seat and made her way outside of her office to stand next to her colleagues. "Hey, what're you guys talking about?"

"Danny was just telling me that-"

"Steve's back. He just called me a few minutes ago and told me he landed this morning. He'll be gracing us with his presence momentarily."

"Oh wow, that's great." She forced a smile. "It's been so long since we've seen or heard from him."

"Seems like it's been longer than four years." Chin added.

"Now that he's back from his 'highly classified mission', maybe we can see about getting five-0 up and running again."

Kono stood in silence watching them interact as she silently began to panic at the thought of seeing McGarrett again; her mind began to race uncontrollably.

"Is he back for good or is he on temporary leave?"

Uncertainty formed on Danny's face. "That I don't know, but we can ask him when he gets here."

"Why don't you just ask him now?" the familiar voice asked from the doorway.

They all looked over seeing Steve standing at the doorway with his large duffle bag in hand. He grinned as he dropped the bag onto the floor and Chin was the first to walk up and greet him. Next up was Danny who let out a laugh and pulled his best friend into a bear hug. Kono stood at a distance watching the guys interact with each other; she swallowed hard and forced a simple smile when McGarrett walked over toward her slowly. She thought her heart was going to beat out of her chest.

Steve pulled her into a gentle embrace, carefully wrapping his arms around her waist as if she were fragile and took in the light scent of vanilla that radiated off her soft skin. "Good to see you, Kono."

She wrapped her arms slowly around his neck, feeling weak at the knees as his body pressed against hers. Those secret nights they had spent together years before flooded into her mind. She felt the familiar chill that ran up her spine every time she felt his breath hit her neck. She didn't want to admit it to herself, but she missed him and she knew it. "Good to see you, too, Steve."

He gradually pulled away and faced Chin and Danny. "So what's new? What's been going on these last four years?"

"Danny remarried Rachel and-" Chin answered.

Steve's eyes widened, he smiled and grabbed onto his shoulder. "Wait, what? When did this happen? Congratulations, Danno."

"Thank you, you're a year late, but I appreciate that. Chin here proposed to his girlfriend last week… and Kono took the plunge herself."

Steve turned his head toward Kono and smirked at her; making her feel sick with nerves. "That so? Who's the lucky guy?"

"Adam." She answered, successfully hiding the nervousness.

"Congratulations. You too, Chin. Listen, How about tonight we all go out to celebrate? My treat."

"Wish I could, but Rachel, Grace and I have a date night. It's the only time we really get to spend time with Grace now that all she wants to do is hang out with her little friends."

Chin sighed. "I can't tonight either. I promised Nina I would go with her to her niece's dance recital."

"I could go…Adam is working late, it'll be nice to catch up." She blurted without thinking, mentally kicking herself for doing so.

McGarrett smiled. "Ok, then. I'll see you later on tonight. We'll all grab a drink sometime this week. Now if you'll excuse me, I'm going home to get some sleep."

"Wait a minute; does this mean you're back?" Danny questioned.

"For the time being, yes, Daniel… I'll see you guys later."

Watching Steve walk up toward the door, grab his duffle bag and leave their office was like slow motion for Kono. A part of her was still in disbelief that he was even back in their lives after thinking that she may never see him again. Once he left, Kono told Danny and Chin that she was going back to her office to finish up her paperwork. When she reached her desk the only thing she could focus on was her last night with Steve.

/Flashback-Four Years Ago/

Steve groaned tiredly as he gave one last deep thrust and reached his climax. He could still feel Kono trembling beneath him due to her intense orgasm just moments prior. A moan escaped his lips as he continued to feel her pulsating around him before he slowly pulled out of her and collapsed beside her onto the bed. He wrapped his arms around her bringing her close to his chest and attempted to regulate his heavy breathing. While his fingers grazed through her damp hair, she swallowed hard and looked into his eyes as she placed a hand on his face.

"You don't have to go, Steve. It's not mandatory."

"It is for me and you know that, Kono."

She began to breathe easier. "You didn't have to agree to this mission."

"Of course I did. I made a commitment to my country, if they need me I'm there."

"What about Danny? Chin? What about me? We need you."

He cupped her face, looking sadly into her eyes. "I thought you of all people would understand why I'm doing this."

"I do understand, it's just…" she closed her eyes and touched his forehead with hers, "I really don't want you to go."

"Hey, look at me. I'll be back." He smiled.

She opened her eyes. "When, Steve?"

"Honestly, I don't know."

He leaned in and gently kissed her lips before getting out of the bed. Kono sat up in her bed and covered herself with the bed sheet as she watched him dress. "Please don't go."

"I have to, Kono, I'm sorry."

After wrapping the sheet around her body, she got out of the bed and walked up to him as he buttoned up his shirt. "You can't."

"My flight leaves in two hours. Why are you so determined to prevent me from leaving? You know everything will be fine."

"It's because I love you, Steve. You can't leave."

McGarrett stood there in silence after the confession then took a step closer her. He leaned in, pressing his lips to hers only to deepen the kiss seconds later. She slightly parted her lips allowing him access to massage his tongue gently onto hers, causing her to moan into his mouth. His fingers tangled in her hair, he showed no sign of stopping. Roughly fifteen minutes passed and Steve pulled away from her slowly. They looked into one another's eyes as they tried to catch their breath. "I'll see you soon."

/End of Flashback/

Kono jumped when she heard the knocking at her door that brought her back to reality. Her eyes widened and she quickly changed her expression to happiness when she saw Adam. She loved her husband, but now that Steve was back her thoughts and feelings were all over the place.

He walked in to her office with a smile on his face and a bag in hand. "You've been busy lately and so have I, so I thought I'd come to see you and bring you lunch."

"You didn't have to." She stood and smiled to be polite.

He stepped toward her, placed the bag on her desk and wrapped an arm around her waist. "I wanted to. I also came to ask you if you wanted to go out to dinner tonight. I moved some things around in my schedule so I can spend some much needed time with my beautiful wife." He placed a kiss on her neck.

"Oh, I'm sorry, Adam. Chin and I are…going on a stakeout tonight. Rain check?"

"Sure. No problem." He smiled sadly. "I should get going. I have a meeting in a half an hour. See you later then?"

"Yeah. See you later."

Adam pecked her lips and looked into her eyes lovingly. "I love you, Kono."

"I love you, too." She answered with less conviction, not enough to alarm him.

As he walked out of her office, Chin walked in moments later. "So we're going on a stakeout tonight?"

"Chin…"

"Look, Cuz, you know I'll cover for you. I just want you to be careful."

"What do you mean be careful?"

"You think I was born yesterday?" he sighed. "A few months before McGarrett left, I noticed things were different between you two. It didn't take long for me to put two and two together. After he left, I noticed a change in you and how much you were hurting. All I'm saying is that you're married now, Kono, you need to be smart."

"I appreciate what you're trying to do, Cuz, but don't worry about it. What happened with me and Steve is secret ancient history and it wasn't serious…wait, does Danny know?"

"I don't think so, but that's not the point-"

"I know the point, Chin. You have nothing to worry about, I promise."
