Chapter 11

"Your apartment is amazing!" Addison gushed to Meredith a month later. Meredith and Derek had signed the lease and moved in two weeks ago, and Meredith wanted to throw a party, the date coinciding with Derek's thirtieth birthday.

"I know, I absolutely love it," Meredith replied. "And it's not that far from you, so you'll have to come visit when you aren't working."

"Of course, now that Cristina's in Boston you need to find some sort of temporary replacement," Addison laughed.

"That's true, I need to train you," Meredith joked.

"What did you end up getting Derek for his birthday?" Addison asked.

"Umm," Meredith began, blushing a little. "Well, he told me he didn't want anything because we just signed the lease on the apartment, and I paid the first month's rent. But I bought him a few CDs, which he liked, and a more, uh, adult present, which he hasn't seen yet."

"Uh huh," Addison said, raising her eyebrows at her. "You two have way too much sex. I'm starting to think that Mark made a mistake in kicking the two of you out."

"What mistake did I make?" Mark asked, sauntering over to Meredith and Addison.

"Kicking Derek out of the apartment. I bet all they do now is have sex all over the place," Addison responded.

"Hey!" Meredith exclaimed, turning red and not denying Addison's accusations.

"I did not kick Derek out," Mark insisted. "He and Grey voluntarily left."

"Right," Addison scoffed. "After you walk in on them with your new roommate the morning after they got engaged. Did you really think that they were planning on leaving that room at all that day?"

"Hey!" Meredith repeated. "We were not going to be having sex all day; I had to meet Cristina and Izzie for lunch, so I was getting up. And anyways, that was a month ago; it doesn't matter now."

"Mhmm," Addison smirked. The three chatted for a few more minutes while more guests arrived, mostly Derek's sisters with their husbands and kids. She spotted Derek across the room, and her stomach did a somersault. He was wearing a light blue shirt that brought out his eyes, and his hair, as usual, was perfect.

He was talking with his mother and Nancy, both of whom were handing him presents. She watched him talk animatedly with his family, pointing out different features of their new home. He eventually moved away from his mother to put her gift on the coffee table, and their eyes met. Meredith raised her eyebrows and smiled suggestively, watching him tense. Within five seconds he had crossed the room, took her arm, and pulled her into the hall.

Leading her down the hallway, he opened the first door on the right, the laundry room, and practically pushed her inside. After flipping on the light and shutting the door, he pulled her face towards him and kissed her hard. Meredith instantly responded, her hands automatically going to his hair.

He gripped her waist as he lifted her up and sat her on the washing machine, his lips never leaving hers as he moved to stand beneath her legs. He continued to kiss her passionately; Meredith opened her mouth so his tongue could mingle with hers. She moaned softly as Derek bit down lightly on her lower lip, getting lost in the way Derek made her feel.

It wasn't until his mouth left hers, kissing and sucking his way down her neck, that Meredith began to think again. And as Derek began unbuttoning her jeans, still assaulting her neck, she heard a thud coming from another room. This noise snapped her back to reality; there were people outside the laundry room, a lot of people.

"Derek," Meredith gasped, her hands moving from his neck to his chest in an effort to push him away.

"Yes," he moaned, kissing her deeply again.

"We have to stop," she said forcefully.

"No we don't," Derek argued, leaning towards her again as Meredith successfully pushed him away.

"Yes we do. There are thirty people out there right now. And these people are celebrating your birthday and admiring our apartment. And we aren't out there. They are eventually going to wonder where we are, and our place isn't all that big, so they'll find us pretty easily. And I am not having your mother listen to us having sex."

"But it's my birthday," Derek whined, looking at her with pleading eyes. "And I want sex. And we never deny each other sex on our birthdays."

"You already got sex six times today," Meredith argued as she rebuttoned her jeans.

"Yeah, but two of those times don't count," Derek said as if it were the most obvious thing in the world.

"And why not?" Meredith scoffed disbelievingly. "As I recall, you were very happy, and very, very satisfied, each time today."

"I'm always satisfied with you," Derek smirked. "But, we had yet to christen two of the rooms, so the study sex and the laundry room sex technically still fall under move in sex. So I should get sex now."

"Derek, no," Meredith said firmly as she hopped off the washer, fixing her hair quickly before stepping closer to him and kissing him. "But, I promise that there will be a lot of dirty sex for you tonight."

"Fine," Derek sighed as he led them out of the laundry room, but he couldn't keep the smile off of his face. They left the laundry room as inconspicuously as possible, moving back into the main room.

"Meredith," she heard a familiar voice call behind her. Turning around, she smiled at Carolyn Shepherd as she walked towards the two of them, pulling Meredith into a hug. "Your home is lovely! Now, I tried to ask Derek about any wedding plans, and he told me to talk to you. So, do you have any news?"

Meredith shot Derek a look. "You didn't want to tell your mom about your own wedding?"

Derek chuckled and kissed the top of her head. "I don't think I would have done an adequate job. She would want a girl's perspective."

Meredith rolled her eyes as she turned back to Carolyn. "We were thinking next summer," she responded to Carolyn's questioning stare. "And we kind of wanted to have a small wedding and reception. You know, immediate friends and family, buffalo wings at the reception sort of thing."

Carolyn smiled at her. "That sounds like a lovely idea. Perfect for the two of you."

Meredith looked up at Derek, who pressed a quick kiss to the top of her head. "Yeah, we thought so too."

XXXXXX

Meredith woke up the next morning to Derek shifting his arm on her waist. She turned around in his arms, pressing herself against his naked chest. Opening her eyes slowly, he was smiling down at her, smirking. "Good morning," he whispered as he kissed her on the lips.

"Morning. How long have you been up?" Meredith asked.

"Just woke up."

"Good. Did you have at the party?"

"The party was alright," Derek said, still smirking. "But I had a great time before the party. And an even better, mind-blowing time after."

"You make everything dirty," Meredith rolled her eyes at him, but grabbed his hand and laced their fingers together.

"Oh, I forgot to tell you something yesterday," Derek said, suddenly very excited.

Meredith propped her head up on Derek's chest, looking intrigued. "What?"

"I got it," Derek said, squeezing her in his arms. "Chief Resident, I got picked."

"Ah, no way Derek!" Meredith screeched, leaning up to kiss him. "I'm so proud of you!"

"Thank you," Derek said, pulling her closer. "I was really surprised they picked me."

"Of course they picked you, you're a rock star in the OR. Why didn't you tell me when you found out?"

"Well, it was posted yesterday morning just as my night shift was ending," Derek explained. "And I meant to tell you, but you were still asleep when I got home and I was just so tired, I wanted to sleep and meant to tell you when I woke up. But then it was my birthday so you had stuff planned, and then there was the party, and then we had our own, private celebration last night. So, now is the time I'm telling you."

Meredith nodded at him still smiling with pride over him. "I love you."

"I love you too," he said kissing her firmly and pulling her on top of him. "You want to know what goes great with getting picked for something?"

"What?" Meredith giggled against his lips.

"Celebration sex," he said seductively.

Meredith laughed, moving to straddle him. "Addison was right."

"Right about what?" Derek asked as he trailed kisses along her neck.

"All we do now is have sex," Meredith half moaned, giving in to Derek's exploration of her body.
