A/N Sorry about the delay everyone. Enjoy this chapter.

Choices

Addison Montgomery was sitting at her desk at Oceanside Wellness doing her best not to think about Derek Shepherd. It was much harder than she realized to not think of her ex husband who had kissed her when they had gone to New York together. Addison couldn't get that kiss out of her head. He had smelled like cinnamon and Addison had never wanted to kiss him more than she had on that night. Kissing him had caused her to go weak in the knees just like it used to when they had first met. Having him pick Meredith over her was such a huge blow to not only her ego, but more importantly, her heart as well. She hadn't even heard the phone ring. She was finally pulled out of her daydream by the ringer being louder than before. She grabbed the phone and put it to her ear.

"Hello?" Addison had no idea who was on the other line.

"Just the woman I wanted to talk to. Hello Addison." Her old mentor Richard Webber called into the phone. Addison had no idea what this was about, but she prayed that Richard wasn't asking her to come to Seattle for a case. She couldn't go to Seattle and see Derek and Meredith happy and in love. She was a strong woman but not that strong.

Hello Richard." Addison greeted him with a fake smile plastered on her face.

"Listen I know you are busy so I am just going to ask you a favor. Sixteen year old pregnant girl. She's expecting twins and just last week found out that they are conjoined. Her parents are in total support of her and the babies. They have heard a lot about you and they asked if I could get you here." Richard explained.

Addison sighed heavily. She hated it that Richard could get her like this. She needed to cut. She was a surgeon first and foremost and she hardly ever got to cut in LA. If a patient's family was actually asking for her, she had to go help.

"Okay, the answer is yes." Addison finally told Richard.

"There's a catch. She is three months pregnant so your commitment has to be for the next six months." Richard told Addison gently.

Addison could not believe this. In Seattle for six months? At least Callie and Mark wouldn't have to travel to LA to see her anymore. But she would have to face Derek and she wasn't sure she was ready to do that. Especially if he and Meredith were happy together.

"Okay, I can do that." Addison finally agreed. This wasn't for Richard. It was for the sixteen year old who was going to have two special children in six months.

"Excellent. So when can I expect you?" Richard asked Addison.

"I'll fly in tomorrow afternoon." Addison informed Richard.

"Looking forward to having you back Addison." Richard told her.

"I'm not back Richard-"Addison had started to say but Richard had hung up on her. Addison scowled as she hung up the phone and went to go talk to Naomi.

---------------------------------------------------------------------------------------------------------------------------

Derek was in Seattle and he couldn't get Addison out of his mind. He hadn't been able to since he had come home from New York. He had come to the realization that he loved her and he wanted to give them a second chance to be together. First he had to end it with Meredith. She would never trust him and Derek felt as though he needed the woman he loved to trust him. She would never end it on her own, So Derek had to do it. Derek was in the on call room waiting for Meredith. They had these little on call meetings at least once a day so Derek knew that she would come. They usually spent time in here having sex. Derek just hoped that Meredith hadn't worn any fancy lingerie today. He heard the door open and Meredith walked into the on call room. She saw Derek and she crawled onto the bed that he was sitting on.

"Get naked." Meredith ordered. Derek looked at her and shook his head. He had not paged her here for sex today.

"We need to talk Meredith." Derek told her quietly.

Meredith sat up and looked at Derek. She had no clue what Derek was talking about.

"About what Derek?" Meredith demanded.

"I can't be with you anymore." Derek told her as gently as he could.

"Why the hell not? I have done everything for you and you are just throwing it away. I made a fucking house of candles for you." Meredith snapped. She couldn't believe that her McDreamy was doing this to her. Then she remembered the New York trip that he had taken with Mark and Callie…and Addison. Meredith was pretty sure she had just hit on the reason that Derek was ending it with her.

"You had sex with Addison, didn't you?" Meredith accused.

"No I did not have sex with Addison." Derek answered her truthfully.

"But you wanted to." Meredith finished spitefully.

"Meredith, please you and I are not as right for each other as I thought we were. You deserve someone who loves you and I am not that person." Derek told her as gently as he could manage.

"You really love her, don't you?" Meredith murmured, her voice suddenly soft.

"I do. I don't say this to hurt you, but going to New York with Mark Callie and Addison made me realize how much I still loved her." Derek admitted.

"Then fight for her Derek. You hurt her…we both did and she deserves better than that." Meredith murmured.

"Thank you for understanding Meredith." Derek told her softly. Maybe Meredith wasn't as much of the jealous type as Derek had feared.

"Make her happy. Make her happier than you made me." Meredith told Derek before she got off of the bed and walked out of the on call room.

Derek was stunned. He had had no idea that Meredith was going to take it so well. Sure she had been upset with her in the beginning, but she ended up being really nice and supportive about the whole thing, which Derek was grateful for. Derek had plans to make and he needed to start on them as soon as he got to his office.

-----------------------------------------------------------------------------------------------------------------------------

Derek was heading off to his office when Richard stopped him in the hallways. Richard had heard rumors about what had happened when two of his Department Heads and his best Orthopedic resident had taken off to New York. He wasn't sure how much of it was true and maybe it was best if he didn't know any of it. Especially the part about Derek kissing Addison in New York.

"Sorry, Richard. I can't talk right now." Derek told Richard, attempting to sidestep his boss.

"Listen I just came to find you and let you know that Addison is coming to Seattle. OB has a case and the parents have asked for Addison to be the one to take care of the teenager's pregnancy." Richard told him. Derek froze in stunned silence. Addison was coming here. To Seattle. He could hardly believe his good luck.

"How long will she be here?" Derek asked curiously.

"It's a six month commitment." Richard told him.

So even if Addison didn't believe him right away, he still had six months to convince her that he loved her and he wanted to make a life with her just like he had promised her twelve years ago. Derek couldn't believe this. He was beyond thrilled.

"Thank you for letting me know Richard." Derek told Richard as he tried to hide the grin that was threatening to come to the surface. He faked a page and then ran off, hoping that Richard had no idea what was going on. Derek didn't feel like explaining it to his boss. Especially not after just ending it with the daughter of the woman Richard had had an affair with.

--------------------------------------------------------------------------------------------------------------------------------

Mark and Callie were finally house hunting. They had finally gotten a day off where they could go look for two houses. They wanted to find two houses close to each other so it wouldn't be a long commute for either of them when the babies arrived. Mark would have rather live with Callie, but ever since her parents had left Seattle, she had stopped kissing Mark and they had gone back to being just friends. Mark didn't like that at all. He wanted to be more than her friend and he couldn't believe that she hadn't realized that yet. Mark wasn't about to point it out to her only because he wanted her to figure it out on her own.

Their realtor was a woman about Callie's age named Margo and Callie could tell that Margo was flirting with Mark. That did not make Callie happy. She didn't want this woman putting her hands all over Mark. Mark was Callie's and Callie's only. Callie just wished that she could tell Mark how she felt about him. How she wanted him to crush his lips on hers again until Callie saw stars. She wanted to move in with him, but she was almost sure that Mark did not want that. Callie wished she had the courage to come out and ask Mark if he would move in, but she didn't. Margo was showing them a two story house with a spiral staircase that Callie loved. They had already gone house hunting for Mark but he had yet to find something that he liked.

"I love this." Callie told Margo in an effort to stop Margo from "accidentally" brushing against Mark. To Mark's credit though he was not flirting back. He was staying at Callie's side with his hand on her shoulder.

"Are you ready to make an offer?" Margo asked eagerly. She needed to sell her very first house as soon as possible before her probationary period was up.

"I am giving them full price." Callie told Margo. Mark looked at Callie as if she was insane. He couldn't believe that she wasn't trying to negotiate the price down just a little bit. Margo was shocked too, but she nodded.

"Come by tomorrow and we'll draw up the papers." Margo told Callie with a smile showing her perfect white teeth.

"Excellent." Callie agreed with a grin splitting her face. She had fallen in love completely with the house from the moment she had stepped into it.

Of course Mark was frustrated that he couldn't seem to find a house that he liked. Maybe he was supposed to be living with Callie in her brand new house with their two babies. Mark watched Callie go sign the preliminary papers and then when she walked back to him, Mark rested his hand on her stomach. He was waiting for the day that they could feel the babies moving.

"Let's go back to the hotel." Callie told him. Callie had him wrapped around his little finger already and all he wanted now was for her to be happy. He would do anything in the world for her to make sure that she was happy.

RATING- MATURE

A/N This part includes sex so don't read it if you shouldn't be.

A shot time later, Callie was lying in bed with Mark's Knicks t-shirt on and a red lacy pair of panties. Thankfully the shirt was long enough that Mark could forget that she was wearing his favorite panties and he could focus on other things. Mark was now eating his fourth slice of Meat Lover's pizza and Callie was two slices into it. They had lapsed into a comfortable silence. There were no awkward silences between them. They were comfortable.

Callie had realized as she was eating her pizza on Mark's huge king sized bed that she didn't want to live in that huge two story,4 bedroom 3,000 square foot house alone. She wanted Mark to move in with her and now she didn't care if this showed him that she was crazy about him.

"Move in with me." Callie blurted out. She felt her face heat up with embarrassment when she realized how she had said it. She had not meant to say it like that. Mark was staring at her in complete shock. Was it possible that she cared about him in the same way that he cared about her. Mark wasn't about to turn her down if there was the slightest chance that she was feeling things for him.

"Yes I would love to." Mark told her quietly. Callie wasn't ready to tell him how she felt about him yet. She just didn't want him around Margo anymore. Margo's blatant flirtation made Callie's skin crawl. Callie put down her plate and snuggled close to Mark's body, resting her head on his chest and her hands on her stomach. She was just barely showing now and she was so excited for these babies to come into the world. Mark rested his own hand on her stomach and he looked at the woman that he had on his lap. Before he could help himself, he bent and kissed her plump red lips.

Callie hoped that this meant that he was willing to have sex with her finally. She moved so she was on top of him, her lips not leaving his lips. Callie pulled off her t-shirt and pulled Mark's Columbia shirt off of his chest. Callie was horny and she was in desperate need of sex and Mark was going to give it to her right now. Mark was still shocked that she had managed to get his shirt off without him even realizing what was happening. His hand slid up from her stomach to cup her right breast. Callie moaned at the feeling of Mark's hand touching her breast.

"Don't…stop…"Callie pleaded, already feeling breathless. Her hands went inside Mark's boxers and she ran her hand along his hardness. It was Mark's turn to moan at the feeling of her cold hand on his hardness. His hand ran over the top of her right breast and he flicked her nipple. Her right nipple was now hard. Mark's other hand went down south and he cupped her panty covered wetness.

"Mark I need you inside of me. Now." Callie commanded. Mark smiled before he removed her red lacy panties that left very little to the imagination. The whole plan of not having sex with Callie until she knew how he felt about her seemed to have gone out the window for Mark. Callie pulled on Mark's boxers and finally they were both naked. Mark rolled them both over so he could be on top. He finally slid into her and Callie let out a relieved gasp. Finally Mark was inside of her. Callie wrapped her legs around him trying to make him go deeper inside of her. Mark's lips had never left hers and his hands were now on her round full breasts. He had one in each had and he was playing with them. He rolled her nipples between his fingers and Callie moaned and arched her body so her breasts were pushed further into Mark's hands. Callie was loving how Mark could make her forget the world just by the way he touched her.

"Harder." Callie ordered.

"Bossy." Mark growled in her mouth, but he went harder inside of her just as she asked. Callie's hips were rocking to meet Mark's deep and hard thrusts inside of her.

"Damn…"Mark muttered admiringly as he looked at Callie's naked body before he pulled his lips from hers and latched his lips onto Callie's breasts. He took her nipple in his mouth and he bit on it lightly and then he went to the right nipple and bit lightly on it. His hands had gone to Callie's inner thighs and were slowly spreading her legs wider and wider so he could go deeper inside of her. Callie was almost sure that she was going to lose her mind and it was all Mark's fault.

"Mark…"Callie warned him. She could feel that her climax was only seconds away. Mark heard her and he knew what she meant. He could feel his own climax building up.

"God…Me too." Mark muttered.

They both hit their climaxes at the exact same time. Callie screamed out Mark's name as she dug her fingernails into his shoulder blades, feeling sure she was drawing blood but not really caring. Mark groaned Callie's name out as his hands tightened on her body. They both took some breaths, desperately trying to stabilize their breathing as they came down from their highs.

"Damn that was fantastic." Callie breathed.

"I was going for mindblowing." Mark argued with a smirk falling across his lips. Callie glared playfully at him before she snuggled close to him.

"Thank you. I really needed that." Callie admitted.

"No thanks necessary." Mark told her.

It felt good to Callie to feel sexy and desirable again, especially by the man who she had fallen in love with. Mark didn't know that she was in love with him, but after tonight, Callie was definitely closer to telling him. Mark had no idea that Callie hadn't felt so good about her body lately. If he had, he would have guessed that her need for sex had more to do with her desire to feel sexy and desired again.

Callie looked down at her stomach and she rested her hand back on her stomach. She was tired now and she blamed her exhaustion completely on Mark.

"Your Daddy made me tired." Callie told her stomach. Mark was smirking as he looked at Callie. He seemed to remember that it was Callie who wanted sex in the first place.

"I didn't hear you complaining." Mark teased Callie.

Callie giggled softly and then looked at Mark. He was a good guy and her kids…their kids were lucky to have him as their father. Callie yawned and then drew the covers up over herself. She snuggled herself close to Mark and whispered,

"Good night Mark."

Mark kissed the top of her head with a smile and then laid down himself and pulled Callie into his arms. This time Mark knew she wouldn't pull away from him.

"Good night Cal." Mark whispered before he too fell asleep with his hand on Callie's stomach on top of Callie's own hands.
