A/N: Firstly we want to say wow and then thank you for everyone's overwhelming support of this story. We are both so happy that so many people like it. It's really great that there are so many Addex fans still out there. Hopefully when Kate Walsh comes into Greys for that 1 episode we may get some Addex. We are hopeful but it probably won't happen!

As you know Jaz and I have taken it turns to write a chapter, but as time is going on it is working out that we are both co-writing all chapters now so this one is a definite combined effort. Enough of my rambling we hope you enjoy!!

CHAPTER 6

IT SHOULD FEEL WRONG BUT IT FEELS SO RIGHT

They had spent the past 3 days working together, seamlessly like they always had. Everything was back to normal. They discussed at length the kiss they shared in the bathroom and both admitted that while they liked it nothing could happen again. It was one thing to not want it unfortunately it was quite another for it NOT to happen again. They were attracted to each other, and nothing they said or did would be able to change that.

He found her sitting at the kitchen table a little after 1.00am in the morning. It was their last night in New York; they were headed back to Seattle in the morning after completing a very successful surgery. She looked so lonely, like she was reminiscing about the times she has had in this house. She was leaning back in the chair with her feet propped up on the one beside it and she was staring out the window, her body visibly trembling. His heart ached for her, but all he could do now was be there for her if she needed him. She was his best friend, who as of late, had started to seem like something so much more.

"He doesn't take care of you like he used to, does he?"

She jumped a little, startled by his presence. When she turned to face him, he noticed the tear stains on her cheeks. Alex walked towards Addison and sat in the vacant chair next to her. He didn't touch her though because he was unsure of how she would react in her fragile state. She put her feet flat on the floor again and turned her body to face him.

"Is it that obvious?"

"To me it is."

"Great, it's obvious to everyone but him. God, I'm such a mess."

Alex forced her to look at him and finally said, "Hey. You're not a mess. And it's obvious to me because I'm looking. We've been working together for almost a year now. When people work side by side together every day for a year, they start to notice things. It's gonna happen."

She just sat there for a minute staring at him. It was then that she realized the man who was going to take care of her wasn't going to be the man she was legally bound to. No. It was this

man. Her intern. The one sitting next to her with his hand on hers, telling her that not only was he looking at her, but more importantly, he was seeing her. It had been so long since someone looked at her like that. Yes, Mr. 'I can fit all my belongings in a milk carton' was about to show her what 'really, really great' felt like again. She wasn't sure of the exact moment it happened or who leant in first, but their lips were now caught in an endless dance of passion as his hands twisted in her hair and hers wrapped around his back and pulled him closer.

She got up from her seat and turned to face him, sitting herself on top of the table, her legs dangling off the edge. She smiled down at him as he ran his hands along the tops of her thighs. The look she gave him told him that this was going to be neither slow nor was it going to last long. She yanked his black tank top over his head as he simultaneously did the same with hers, all the while climbing on top of her on the table. There would be time later to explore each other's bodies and all their likes and dislikes. Right now they wanted each other badly. It was simply lust. Pure, raw, uninhibited lust.

They continued to kiss with passion as he roughly pulled her silk Pajamer bottoms off while she pushed his boxers down his legs. They didn't speak, as he pulled his lips from hers and began kissing her neck and making his way down to her chest. Addison wrapped her legs around his hips conveying exactly what she wanted.

Addison gasped and Alex groaned when he entered her totally and completely. He looked down into her darkened, lust filled eyes knowing that she wanted this just as badly as he did. Alex began to move inside her slowly at first but it wasn't long before the months of longing overtook both of them and they moved together in a fast, heated passion. Alex thrust harder and faster and her legs were now tightly locked around his back. They returned their lips back to each other, the feel of his erection buried deep between her legs and his tongue deep in her mouth sent shivers through her whole body.

Just as he felt her start to shake underneath him he moved his hand between their joined bodies and rubbed her clit as he continued to thrust into her. Addison began to gasp and moan as she kissed and lightly bit his neck. Moments later a much needed release took both of them by surprise. They came at the same time, moaning each other names as the intense shockwaves spread through their bodies.

Shortly after their breaths had returned to normal, Alex withdrew himself from her and helped her off the kitchen table.

"Addie, I..." Alex began.

"Don't, don't say anything." Addison said as she looked into his eyes.

They looked at each other for what felt like an eternity, before he crashed his lips to hers again. This time the kiss was much slower and their hands wandered all over the others body slowly exploring.

"Bedroom." Addison muttered.

Alex just nodded his head in agreement and they stumbled their way to the stairs and up into the room Alex had occupied for the past few days. Once in the guest room, they took their time, taking in each other's bodies and spending the time discovering what each other liked, wanted and needed. Alex ran his thumb along Addison's jaw and looked into her eyes before he gently placed his thumb in her mouth. He watched in arousal as she began to kiss and suck his thumb, making him think what else she could do with her mouth, which he was to find out later that night.

They made love repeatedly until the sun was just about to rise.

"We have to be at the airport in a couple of hours." Alex said sadly as he held her close to his chest, stroking her hair.

"I know."

"Addison, I. I mean what do we do now?"

"Alex I have no idea. I know I don't regret this, but other than that I don't know. What do you want to do?"

"I really don't know either. We both have commitments to other people. I need you to know though, I don't regret this either. I have wanted it for so long." Alex admitted.

"Me too, I just don't know where we go from here."

"Do we go back to Seattle, back to working together everyday pretending this didn't' happen?"

"I think it's the only thing we can do. Too many people will get hurt if we let this happen again." Addison concluded.

"Okay, I guess we can try that. I just don't want this to get weird. Our friendship means a lot to me. You mean a lot to me I don't want to lose that." Alex said sincerely.

"Me neither. It will be okay, we will be okay." Addison said before she kissed him lightly on the lips and she crept out of bed.

"Addie, don't go. Sleep here with me for an hour."

"No Alex that will just make it harder. I'll see you downstairs in an hour and a half, before we catch a cab to the airport."

Alex watched her leave the bedroom. He lay in bed staring at the ceiling wondering what the hell had just happened and what they were going to do now.

When Alex entered the living room with his bags, Addison was waiting for him.

"I've called a cab; it should be here in 5 minutes or so."

"Oh great. So um, should we I don't know talk about what happened?" Alex asked tentatively.

"I don't think so Alex. What is there to talk about? I mean like you said earlier we both have commitments to other people. You love your wife and I love my husband." Addison said with a shrug of her shoulders.

"Yeah I guess you're right. It shouldn't have happened. So I think the best thing to do is pretend it didn't and go home." Alex said with that slightly rude tone he can get in his voice.

"Yeah we go home, back to our spouses and remain the good friends that we are, and get back to being the best surgical team at Seattle Grace. Last night never happened. It was mistake, a mistake that won't happen again." Addison agreed firmly.

"No it won't. Maybe we should just keep our relationship professional for a while."

"Good idea."

Just then, the cab arrived to take them to the airport. Once they checked their bags, Addison busied herself in the book store looking for a new book so she could at least pretend to read it on the flight home so she did not have to make conversation with Alex. She had to say it was a mistake; she had to tell him that. But it her mind it wasn't a mistake at all. It was perfect. If she were honest with herself it was beautiful. Making love with Alex was beautiful, pure and yeah lust- filled but beautiful none the less. His kisses would forever be engraved in her mind.

Alex bought a newspaper and a sports magazine hoping to not have to talk. He was starting to get nervous about the flight. He hated the take off so much that at least until he was in the air he could focus on something else. He knew he didn't mean it when he told Addison it shouldn't have happened. But seriously what else could he say? He had a wife who was waiting for him at home. A wife that he didn't think about in the way he should anymore. That was going to change, he was going to try and fall back in love with his wife, stop taking her for granted. It was a good idea to tell Addison that they should keep their relationship professional for a while, it would give him the time he needed to stop remembering what her body felt like in his arms, and what her lips felt like on his, which was something he knew was going to be hard to do. Touching her, making love to her was just sublime, and as much as he didn't want to admit, probably the most amazing sex he had ever experienced. It was total body, mind and soul.

They barely spoke as they took their seats on the plane. Addison's heart was breaking as she could see how nervous Alex was becoming. He was fidgeting and making sure his seatbelt was as tight as possible. He looked so vulnerable, which if anyone knew Alex Karev, they certainly would not believe it if they were told. Just as the plane began to taxi down the runway, Addison took his hand in her own and squeezed it.

"It's okay Alex, I'm here." She whispered just loud enough for him to hear.

Alex placed his other hand on top of hers as he closed his eyes. As soon as the plane was safely in the air, Addison removed her hand.

"Thank you. I'm sorry for being such a baby." He said trying to make light of his fear.

"Don't be silly, just remember this when I'm ever stuck in the dark somewhere and I need your help."

"Well I will be happy to help you." Alex said smiling.

Addison picked up her book and began to fake read; Alex did the same with his newspaper. The rest of the flight went by uneventfully. They only made polite conversation where necessary.

They landed at the airport, and were greeted by their respective spouses. Addison was very surprised to see Derek as she thought she would have to catch a cab home. She didn't know if she was happy or not to see him.

Izzie threw herself into Alex's arms and began to kiss him. Derek was a little less enthusiastic but took Addison into his arms and kissed her lips softly.

"I've missed you so much Alex. I'm so glad you're home. Please don't go away again." Izzie gushed with tears in her eyes.

"I'll try not to; the surgery was a great success though. It was great for my career so I'm really happy. But I missed you to Iz." Alex said not knowing for sure if he did miss her but wanted to squash that thought immediately. He was going to try he had to.

"It's good to have you home Addie. I bet it was great being back at the Brownstone though." Derek said.

"Yeah it was. I love that house. It has lots of great memories." Addison said thinking a little guiltily how she had just created a new memory only last night.

Alex held Izzie close but his eyes locked with Addison's as she held Derek in her arms. They both continued to look at each other. What both of them were really thinking was it was each other they wanted to be holding not their respective spouses. The vows Addison and Alex made to each other to keep things professional were going to be very difficult indeed.
