5.12--Anne Frank

Lexie Grey opened the front door of her sister's house slowly. "Finally." She opened the door fully, allowing Mark Sloan entry. "Where did you park?"

"Around the corner." Mark's head tilted slightly down, as he gave her a kiss. "Hi." He smiled.

"Hi." Lexie giggled slightly. "I'm glad you came."

Mark nodded. "Me too." He walked further into the house. "So where is everyone?"

"Out to eat, movie, and late night grocery shopping." She smirked, "They won't be home for hours."

"Why didn't you go with them?"

Lexie shrugged. "Rather be here with you instead." She motioned up the stairs. "Want to go to my room?" She asked innocently.

"Why Little Grey, are you trying to seduce me?" Mark asked as Lexie lead the way up the stairs.

Lexie smirked. "Why, is it working?"

Mark shrugged. "It's not like you would have to try very hard."

"But that is all part of the fun." Lexie grinned as she walked into her bedroom.

Mark looked around her bedroom/attic. He studied the dozen or so pictures on her dresser. "I gather you like pictures."

"Yeah, it was like my Mom had a camera glued in her hands growing up. She was always taking pictures." Lexie explained.

He picked up one of the pictures, which had Lexie; another girl that he assumed was her sister, and an older woman. All three had huge smiles plastered on their faces. "Is this your Mom and your sister?" Mark frowned, "I'm sorry I don't remember her name."

"Molly, and yes it is." Lexie stepped behind him. "That was taken about a month before she died."

"You all look really happy in this picture."

Lexie nodded, "Yeah we were. After I moved to Boston for school I didn't get home much." She placed the picture back onto her dresser. She pointed to a picture of a small black and white dog. "That's Oreo, the dog I was telling you about."

"How long did you have him?"

"Seven years. We got him when I was four, and he died when I was 11." Lexie said, she turned to him and snaked her arms around his waist, "Enough with the old pictures." She smiled slightly before she lightly grazed her lips over his. "We only have so much time alone…Do we really want to waist it by looking at old pictures?"

Mark shrugged, "I kind of like looking at pictures of you." He raised an eyebrow. "And someone is eager? You aren't just using for fantastic sex are you?"

Lexie laughed. "You got me." She told him sarcastically as her hands went to his pants, unbuttoning them, and then she started to work on the zipper.

"Here I thought you were supposed to be the innocent one." Mark kissed her neck as he easily picked her up and placed her onto the bed.

Their clothes were quickly discarded to the floor; Lexie's back arched underneath Mark's hands as their lovemaking intensified. A loud moan escaped from her lips.

"Lexie?" Meredith's voice called out followed by a knock on her bedroom door.

Mark froze in mid thrust, as Lexie struggled to hide a loud gasp. "Mere?" Lexie squeaked. She cursed silently, knowing how out of breath she sounded.

"Lexie is everything okay? You sound really weird?" Meredith asked from the opposite side of the closed door. She turned the doorknob. "Why is your door locked?"

Mark quietly slid off of Lexie and off the bed, laying naked on the floor next the bed, praying that Meredith would not see him.

"Um, just a second." Lexie scrambled out of bed, quickly kicking Mark's clothes and shoes under her bed. She put on her over sized fuzzy purple bathrobe and opened the door. "You're home early."

"Yeah, the movie we wanted to see was sold out…" Meredith studied Lexie closely. "Are you feeling alright?"

"Um…"

"You just look a little flushed…And sweaty. Were you sleeping?"

"Yeah, um, I don't know what it is…After you guys left I just started to feel a little, um, queasy."

"Oh. Well I hope it's not the flu." Meredith said. "Go back to sleep. Maybe you'll feel better in the morning."

Lexie nodded, "Maybe. Goodnight."

"Goodnight." Meredith said, as she walked away.

Lexie shut the door and quickly locked it, she leaned against it and sighed. "That was close."

"So much for them not being back for hours." Mark mumbled, as he got up from the floor, still naked. "How am I supposed to get out of here now?"

"It's getting late, they should be going to bed soon. You can sneak out then."

"What should we do until then?" Mark asked, sitting on the bed.

Lexie shrugged, "Enjoy each other's company?" She sat next to him.

"You know…We could get back to what we were just doing…" Mark said as he began to remove her bathrobe.

"You think so?" Lexie asked, smiling slightly.

"We just need to be really quiet…"

Lexie giggled, "Do you really think that is possible for me?"

Mark smirked, he kissed her naked collarbone, "Don't worry about that, every time you start to…Be loud, I'll just kiss you."

Lexie grinned. "I think I can handle that."

~~*~~

"Wow…" Lexie gasped as Mark collapsed next to her. She turned to him, her finger tracing his bicep. "I never would have guess quiet sex would have been that great…"

"Mmm…" Mark pulled her closer. "What time is it?"

Lexie lifted her head and looked at her alarm clock. "3:32."

"Is everybody in bed yet?"

"I don't know." Lexie got up from bed.

"Hey!" Mark frowned. "Where you going?"

"I'm going to see if everyone is in bed yet." Lexie said as she put her bathrobe back on. "And I'm hungry. I'm going to get a snack. Would you like one too?"

"Yes please." Mark grinned, "Can you grab me a water to?"

"Sure." She smiled. "Stay put, I'll be right back."

Lexie tiptoed down the stairs and quickly realized everyone was still awake. And cleaning.

"Oh no are we being too loud? Did we wake you up?" Izzie was the first to notice Lexie.

"No…I just came down to get some water…" Lexie said. "Why are you guys cleaning at 3:30 in the morning?"

"Derek's mother is coming." Meredith explained as she obsessively scrubbed the end table with a dust rag. "This place needs to be spotless." She paused for a moment. "You feeling any better?"

"Um, yeah, a little." Lexie brushed her hair behind her ear. "I'm really tired though, so I'm just going to get my water and go back to bed."

Once in the kitchen Lexie grabbed two bottles of water, shoving them in her bathrobe's pocket. She opened the freezer and grabbed an unopened pint of ice cream, she sighed in relief when that to fit in her pocket as well. She grabbed two spoons from the drawer and quickly walked past her roommates, hoping no one would notice her bulky pockets. She sighed in relief when no one did. She shut and locked the door behind her when she got to her room. "Hope you like chocolate chip cookie dough ice cream." She sat next to him on the bed, handing him his water and a spoon.

"They still up?" Mark asked as he took a spoon full of ice cream that Lexie had.

"Yep."

"They better all be sleeping by the time we are done with this ice cream." Mark took another bite.

"This bathrobe is too damn hot…" Lexie complained. She felt the floor next to the bed until she felt fabric; it was Mark's shirt; that would have to do. She slipped it on, tossing her bathrobe to the floor.

"You look good in my shirt." Mark commented. He rested his head on her pillow, "I like your bed."

"Really? The mattress is kinda old…I've used it since high school. The one you have at The Archfield is a lot more comfortable."

"Yeah, but it doesn't smell like you." Mark mumbled under a mouthful of ice cream.

"What did you say?" Lexie asked, not quite sure is she heard right.

"Nothing." Mark quickly said, "Nothing…Forget I said anything."

"Fine." Lexie smiled brightly, she must have heard right.

Mark stood up and started to search for his clothes. "I got to get going…It's so late…Well early…"

"I suppose you want your shirt back?" Lexie grinned as she started to take it off.

"No." Mark stopped her. "Keep it. Like I said you look good in it. Hell of a lot better then I do." He leaned over and kissed her.

"So you are going home shirtless?" Lexie asked, raising an eyebrow.

Mark shrugged. "I have a jacket." After he put his pants on he quietly peeked his head out her door, he sighed, "Why do you have to live in Meredith Grey's attic?"

TBC....

Hope you enjoyed this latest missing scene. I apologize for any typos…I'm half asleep at the moment. Next part will be 5.12 part 2; the missing scene after Lexie is waiting for Mark when he gets off the elevator.
