Hello all!!! First let me say what a great show Grey's Anatomy is!!! I'm all Addison and Derek!!!! If you don't like them there's no point for you to read this story. The story is kinda Au. I just had Derek choose Addison and forget about Meredith. Basically he is in love with Addison and they are going to stay married. Derek knows about the affair and is ok with it. Reviews rock!!

Disclaimer: Don't own it, if I did Meredith would have died and Addison and Derek would have had kids by now… Damn Shonda…

Chapter 1

Addison Montgomery-Shepherd was pinning. She was pinning for her gorgeous husband, Dr. Derek 'Mcdreamy' Shepherd. And so far she had succeeded. The slutty intern, whom Richard had told her was sleeping with her husband, was way out of the picture. Although Derek had yet to say I love you to Addison, she was pretty sure that he loved her.

A week ago, Addison had permanently moved into Derek's trailer and it had been great from there. They decided to take it slow, waiting a while to have sex, but Addison could tell the waiting was about to end. Addi looked down and saw her husband in surgery.

She wanted him badly right now, but the surgery was keeping him from her. She looked to her left and saw Meredith talking to Izzy. They seemed to be talking about her.

"Hello Dr. Grey. Dr. Stevens." Addison said as she made her way to sit right next to Meredith.

"Hello Dr. Shepherd…" Both answered uneasily. Meredith pretty much hated Addison for taking away her Mcdreamy and Izzy was friends with Meredith, so she had to hate her as well.

"Dr. Shepherd, his pulse is dropping rapidly!" one of the interns told Derek as he worked to finish before the patient bled out.

"Thank you, Dr. Yang. Just give me a few seconds" Derek trailed of as he stopped the pulse from dropping and he breathed in a sigh of relief. He looked up into the gallery and saw Addison talking to Meredith. He smiled. Addison looked absolutely beautiful. She was wearing his favorite black skirt with a baby blue blouse.

Derek wished he could rip that shirt right off his wife's beautiful body… He blushed as his wife locked eyes with him. She shifted her legs and gave him a nice few of her black panties. He gulped. Derek then watched her walk out of the room, very slowly. Derek wished that his surgery would end real soon. He got his wish two hours later.

"Grey, would you like to present?" Addison asked as Grey opened the patient folder.

"Sure, patient 26 year old Claire Bennet showing signs of premature labor.." Meredith was cut of by Addison's pager. Addison apologized and looked at it.

"I've got to go, I've got an emergency. Grey, can you take over?" And without waiting for a response Addison walked out of the room and headed towards the elevator.

Addison burst into the hospital room and saw her husband on the bed.

"Derek, honey, what's the emergency? I got a page 911?" Addison asked worriedly.

" I need you babe!" Derek said as got off the bed and shut the door.

"So, Derek, you thought you could just page me, lie to me and then have sex with me?" Addison asked, not believing her husbands stupidity.

"Yeah… Please?" Derek said with his Mcdreamy look.

"You are unbelievable! First you say 'no sex, lets wait' and now you just can't wait to get into my pants. I wanted to do it last night, but no, we were going to wait… Do you think our sex life depends on when you want some of this?" Addison said as she smacked her ass.

"yes… I mean no, Addi, I'm over Meredith. I swear on our marriage. I love you. I always have and I always will" Derek said looking straight into Addison's eyes. Without warning Addison pushed Derek against the wall and began to kiss him. Derek quickly pulled his scrub top off and threw Addison's lab coat into the corner of the room. After he unbuttoned Addison's blouse he practically tore it off and began kissing her neck. She reached for his pants and searched for the drawstring.

"Dr Shepherd…" Meredith stopped in mid sentence. Derek had his hands on Addison's ass and Addison had her hand in Derek's pants. Meredith stared at them shocked. Addison was the first to recover. She quickly tore her hand out of her husband's pants and turned around to face Meredith.

"Yes, Dr. Grey?" Addison asked as though they were strolling in the park.

"Miss. Bennet is going to labor. I just thought you ought to know" Meredith turned on her heels and sped out of the room slamming the door behind her. Addison began to laugh and Derek soon followed.

"That was the definition of awkward" Derek said as a grabbed Addison's shirt and handed it to her.

"it was pretty funny though" She started laughing again as she buttoned up her shirt and pulled on her lab coat.

"So I guess we'll have to finish this later.." Derek said with a frown.

"I'll make it up to you later, babe" Addison gave Derek a long kiss and then walked out of the room. Derek couldn't wait to get home tonight, little did he know how long today was going to be.
