"Get out."

Derek frowned as he looked up from massaging Meredith's back, his eyes settling on Liz and Addison as they stood in the doorway of his bedroom. "Excuse me?" he asked with a raised eyebrow.

"We're have a girl's day," Addison said as she moved into the room. "Hi Mer. We have chocolate."

"Oh, thank God," Meredith breathed, reaching for the brownie Liz offered her. "Get out," she said turning to Derek.

"What?" he asked.

"Derek, I love you, and you've been amazing," she breathed. "But I need time with my friends."

"Mark's here," Addison nodded. "You two can go fishing and talk about being a dad or something."

Derek frowned as he looked at Meredith. "Are you sure you're okay?" he asked running a hand over her stomach.

"I'm fine," she nodded.

"Okay," he sighed. "Look, Addie, she can walk to the bathroom, but don't let her go down the stairs, no matter what she says. And if her back really starts to hurt, warm baths help."

"Derek," Meredith rolled her eyes. "I know how to take care of myself. I'm not a five year old."

"Oh, and Mom catching you trying to walk down the stairs the other day was what…a test?" Derek asked.

"That was me being bored," Meredith shrugged. "I have two pregnant friends, lots of chocolate, and lots of girl movies. Trust me, I'm fine. Go fishing or something with Mark."

"Alright," Derek sighed, leaning down to kiss her quickly. "Be good for Mommy, girls," he murmured.

"He's so sweet," Addison smiled as Derek walked out of the room, closing the door behind

"I know," Meredith sighed. "He really is amazing. He's just…always here. Believe me, you guys came just when I was about to kill him. He's here all the time, saying things. It's driving me crazy."

"I love how he talks to the babies," Liz breathed. "He's going to be such an amazing father."

"Have you talked to Shawn yet?" Meredith asked as she flipped through the pile of movies Liz had brought.

"Yeah," Liz sighed. "He's excited about the baby. We're not really together, but…we both love this baby."

"What about you?"

"We're…we're going to see where it goes," Liz sighed. "I think I might move back in with him. Into his extra room. We're not back together or anything, but we are having a baby, and he shouldn't miss out on anything."

"Plus it's easier for you to have sex when the hormones hit," Addison nodded with a smirk.

"Addison!" Liz gasped.

"What?" Addison asked around a spoonful of ice cream. "It's true, right Mer? Pregnancy sex is amazing."

"It's so true," Meredith sighed. "God, I miss sex. Stupid bed rest. I could be having sex right now."

"Mark's been more than happy to comply with those cravings," Addison giggled as she ran a hand over her stomach.

"Derek was too," Meredith nodded. "This one time I went to the hospital when he had an overnight shift and he took me over a conference room table and he did this thing with his hand…"

"Oh, Mark and I did that too," Addison nodded. "It's so amazing. I can't believe how amazing pregnant sex is."

"Derek did this thing where he took his…"

"Okay!" Liz cried. "Sister sitting right here."

"Right," Meredith nodded. "Sorry. I just really miss it."

"I don't blame you," Addison sighed. "I mean, Mark's completely amazing. But I don't think I've ever screamed the way you did in the on call room on Thanksgiving last fall."

"Yeah," Meredith sighed. "That…was probably the best sex ever."

"Hmmm," Addison sighed. "It's just that when you're pregnant everything feels so…"

"Intense," Meredith breathed. "And I swear, it felt like Derek got even bigger when he…"

"Alright, that's it," Liz said. "I'm going downstairs until the talk about my brother's sex life is over."

"Sorry," Meredith laughed. "We're done, I promise."

"You said that five minutes ago."

"We're really done now," Addison smiled. "Lord knows I'll never want to know anything about my brother's sex life."

"Thank you," Liz sighed, getting back onto the bed.

"Hmm," Meredith sighed. "Thanks for coming over to keep me company."

"Are you kidding?" Addison smiled. "You'd do the same for me."

"If you end up on bed rest I promise to come visit," Meredith nodded. "And I'll bring your nieces."

"Hmm," Addison sighed. "Are you excited?"

"Terrified is a more accurate word," Meredith sighed. "But I can't wait until they're here, so I can get out of this damn bed."

"When's your C-section?" Liz asked.

"June fourteenth," Meredith sighed.

"That's still two months away."

"Believe me, I know," Meredith sighed. "I might go early though. I've been having Braxton Hicks every couple days, and Dr. White says they might come before June."

"Will they be okay?" Liz frowned.

"They should," Meredith nodded. "If they come now they'll be in the NICU for awhile, but…they're pretty well developed."

"I'm sure your girls will be fine," Addison smiled. "And then according to Mark our son will marry one of your daughters."

"That's pretty much all Derek's been talking about since he found out Mark's having a boy," Meredith giggled. "And no offense, but the last thing this world needs is another Mark Sloan."

"I'm really hoping that my son will be mostly Montgomery," Addison smiled.

"He'll be beautiful," Meredith nodded. "Now, which movie should we watch?"

XXXXX

"Well, they finally pried you off of Grey's hip," Mark laughed as Derek walked down the stairs.

"Shut up," Derek sighed, moving towards the kitchen and grabbing a bottle of water. "I'm worried, my entire world is in that bed upstairs."

"I know," Mark nodded. "Which is why we should go down to the lake. Between the three little miracles that are on the way we won't have much time to fish anymore. Until my boy's big enough that is."

"The girls are going to fish."

"Says who?"

"Daddy."

"Don't call yourself Daddy."

"Do you want to fish or not?" Derek asked.

"Let's go," Mark nodded, holding up a cooler. "I've got beer."

"I've got sandwiches," Derek said.

"Let's go."

They moved to the garage and grabbed their poles before making their way out to the lake. It was a rare sunny day in Seattle, and Derek had to admit that it felt good to be outside. He wished Meredith could come out with him, he knew that she was going crazy staying in bed all day.

"How's the bed rest going?" Mark asked as if reading his mind.

"It's going," Derek shrugged. "I'm ready for the girls to come."

"You've still got a while."

"I know," Derek sighed. "I'm a terrible father, I know."

"You're not a terrible father," Mark shook his head. "It's not like the kids will be unhealthy if they're born now."

"I know," Derek sighed. "But I want them to stay in there for a little longer. Their lungs aren't fully developed yet, and neither are their brains. It's just better for them to stay in there for longer. I do hate that Mer is miserable."

"I don't know how you're doing it," Mark shook his head. "If this were Addie, I'm pretty sure I would be a complete basket case."

"I have my moments," Derek nodded. "But Mer's depending on me. I can't exactly break down when she keeps needing me to tell her that everything's going to be okay."

"Makes sense," Mark nodded.

"How's Addie feeling?" Derek asked.

"Oh, Addie's feeling good," Mark nodded with a smirk. "She's very good."

Derek laughed slightly. "You're in the sex phase," he sighed. "Lucky bastard."

"Hey, you had your day," Mark shook his head. "Don't think none of us heard when you and Grey snuck upstairs during Christmas dinner."

"Please don't ever tell Mer that," Derek said. "My chances of ever having sex again are getting slimmer by the day, and I don't need her thinking that everyone's heard us doing it."

"She's not exactly quiet."

"Believe me, I know," Derek said. "God I miss it."

"Hey, that move you shoved me in the conference room," Mark said, shaking his head slightly. "Shit, man, I've never heard Addie scream like that."

"Glad I could help," Derek smiled. "And as much as I miss the sex…it will be worth it when I have my little girls."

"Mer's terrified," Mark said carefully, looking closely at his best friend.

"What?" Derek frowned. "What did she say to you? Is she in any pain?"

"Not like that," Mark shook his head. "When you asked me to sit with her last week, we got to talking, and well…she and I are a lot alike."

"What?" Derek frowned. "You and Mer are nothing alike. She's beautiful and amazing and you're…you."

"Thanks," Mark rolled his eyes. "We both grew up in shit families, and your mom took us both into your family as if we were her own children. We're both about to be parents and completely terrified that we're going to be shit parents and our kids are going to end up more screwed up than we are."

"Mer said that?" Derek asked. "She never told me that."

"I don't think she was keeping it from you," Mark sighed. "I just…we had the same experiences. It's easier to talk about a shitty childhood to someone else who had that experience. You're a good husband and a good friend, but you'll never understand what it's like to have parents that don't want you."

"That's what Mer says," Derek sighed.

"See?" Mark said. "We're the same."

"I guess," Derek sighed. "I just never thought of that before."

Before Mark could answer, Derek's cell phone rang loudly from his pocket and he quickly reached for it. "Mer?" he asked. "What's wrong?"

"Hi," Meredith giggled. "Look, I know you and Mark are fishing and manly men,"

"But…" Derek prompted, smiling slightly at Mark.

"But I was telling Addison and Liz about the chocolate pineapple juice you made me," Meredith sighed. "And now…well, we might die if we don't have any."

"Oh, well we can't have three dead pregnant girls on our hands," Derek laughed. "We'll be right up."

"Thanks," Meredith sighed. "I love you."

"Love you too," Derek laughed as he hung up the phone. "We have to do a craving run," he informed Mark.

"What do they want now?"

"Mer's been craving chocolate pineapple juice," Derek sighed as he closed his tackle box.

"What the hell is chocolate pineapple juice?"

"Pineapple juice with chocolate syrup," Derek shrugged. "Mer says that one baby likes chocolate and the other likes pineapple, so it makes sense to combine the two."

"And now she's got Addie craving it?" Mark frowned.

"Not my fault," Derek shrugged.

Mark sighed as they walked into the kitchen, frowning in disgust as Derek poured some pineapple juice into glasses and reached for the chocolate syrup. "This is disgusting."

"Wait until the third trimester," Derek sighed. "This morning Mer asked for chocolate covered pickles."

"I think I just threw up in my mouth," Mark winced.

"It'll be worth it," Derek smiled. "In five months. Two for me."

"Rub it in," Mark laughed.

"Alright," Derek sighed, placing the glasses on the tray. "Do you want to brave the three cranky pregnant women in my bed or are you going to make me do it?"

Mark paused, glancing up at the stairs before he returned his gaze to Derek. "Safety in numbers?" he asked.

"Definitely," Derek nodded, moving towards the stairs. "Here we are," he said as he opened the door to his room and smiled at the three women on his bed.

"What is that?" Meredith asked.

"Chocolate pineapple juice," Derek replied.

"Oh God," Liz gasped, clapping a hand over her mouth as she ran towards their bathroom.

"Why would you bring us that?" Addison frowned.

"Sorry," Derek whispered. "We'll take it away."

"Two more months, Shep," Mark whispered in Derek's ear. Derek sighed as he turned to walk out of the room. Two more months.
