A/N: This chapter just kind of spewed out of me...I was all "Okay I should stop writing now and just post it." And then my consicence was like "No! Keep writing!" The only downside was that these little inspirations came at random hours in the morning.

DPOV

"Don't talk to me," I cut Mark off as he began to say something to me. "I'm here to wait for Meredith and that's it." I sat on the Grey's couch with my arms crossed, Mark perched in the chair opposite me.

"You're luck I even let you in here," he muttered. I had had enough of his damned muttering, and I stood up and walked back to Meredith's room, where she was supposed to be getting ready. I knocked tentatively and opened the door a fraction of an inch.

"Meredith?" I asked. I opened the door the rest of the way and walked in to sit on Meredith's bed next to her. She was lacing her shoes and looked, thank God, like she was ready to head out. I wrung my hands nervously.

"Derek stop! You're making me nervous now!" She put her hands over my own and I felt how abnormally warm they were. She shook them out and took a few deep breaths.

"You'll be fine, Meredith! My Mom is going to love you." I smiled, trying to cover up how nervous I was about Meredith "meeting" my Mom. She had already met her, of course being Mark's sister, but she had yet to meet her as my girlfriend.

"What about your sister?" She suddenly asked. "You have a sister, Derek! You didn't mention her! Oh God she's gonna hate me, isn't she?" Meredith had stood up by now, and was pacing the room at a ridiculously fast pace.

"Meredith. Calm down! I'm gonna go into cardiac arrest just being around you right now." I pressed my hands against her cheeks and pulled her lips to mine. "You look amazing, you are amazing, and absolutely nothing is going to go wrong."

"Okay," she finally said, and she tidied up her room a bit before we began to head down the hall.

"Meredith!" Mark called. "I don't want you out late! With Mom gone I'm obviously supposed to make sure that-" Meredith cut him off with a quick "Shut up," and we were out the door and in my Jeep.

I pulled her lips to mine one final time, knowing that we wouldn't really be making out in front of my Mother, so it'd be best to get it out of my system while we were alone.

"Let's roll," I smiled, pulling my sunglasses down from the visor above my head and pulling out of the driveway. We stopped at a red light on the highway and Meredith reached over and slipped my sunglasses off of my face. She put them on and looked so hot wearing something of mine that I might have gotten a little hard...maybe...

I winked at her and gestured to the road. "If we wreck because the sun is in my eyes, I guess we know who to blame, huh?"

"Yes. You and your poor driving skills. Oh, and I'll be really pissed if we wreck. So don't."

I rolled my eyes and gunned it out of the intersection. "I'll try to resist the temptation."

Thirty minutes later we were stepping into my house.

"Ma!" I shouted, like always. "We're here! Come say hi!" My Mother conveniently stepped out from just behind the kitchen wall, leading me to believe that she had been waiting there since I left an hour and a half ago.

"Hello, Meredith! It's wonderful to see you again! How is Mark doing? I haven't seen him in a while..." she trailed off and looked at me.

"He's doing great! He has a lot of commitments lately, so he hasn't been able to do anything social for a while now."

Thanks, Mer.

"Well that's just a pity. So am I to understand that you are planning on staying for dinner?"

"Yes ma'am, if you don't mind."

"Oh not at all, dear! I miss having a big bunch to cook for. Dinner should be ready in an hour or so, so you two feel free to watch some television or something."

"Thank you, Ms. Shepherd," Meredith responding politely, smiling as I practically yanked her up the first flight of stairs to my bedroom.

"Derek! I want that bedroom door opened while you two are in there." Mom shouted after us. I stopped walking and felt my face burning. I tried to ignore the comment, but Meredith started giggling and poked me in the arm: "Yeah, Derek. Don't you dare try to shut that door and trap me in there with you."

"Like you wouldn't enjoy being trapped in my bedroom with me," I whispered in her ear, aware that she enjoyed it when I brushed her ear with my lips. She shivered, like she always did, and I laughed. "Come on, hostage, let's have some good clean fun."

"There's no such thing." We laughed and I stopped at my bedroom door.

"Are you ready?" I asked in a serious voice, staring straight into her eyes.

"Ew. I don't know if I want to see your room...maybe I can just go hang out in the kitchen with your mother." she recoiled in fake disgust and started to run to the stairs.

I grabbed her before she was able to get away, threw my door open, and tossed her on my bed. She landed with a thunk, and started giggling madly. I didn't join in her laughing and it cut off quickly. She looked up at me, where I stood staring at her like a predator. I walked slowly over to her and she sat up on my bed, backing against the headboard.

"Scared, Meredith?" I asked quietly, getting oh so close to my bed with each step.

"Not at all," she huffed back.

"Well...you should be," I growled and threw myself on top of her. I nipped at her neck while I tickled her gently. She laughed and squirmed in my grasp.

"Let me-go!" She gasped in between bouts of hysterical laughter.

"Nope. Didn't I make it clear? You're mine, Meredith Grey." I stopped and pressed chaste kisses to her chin and jaw. She panted as she tried to calm down before saying: "I don't think you made it quite clear enough, Derek."

"Oh," I stroked my chin thoughtfully as I hovered over her. "We'll have to make it a little more obvious then, won't we?" I went at her neck without even bothering to kiss her first. I nipped at a sensitive spot I knew she loved and she let out a deep breath. I had just started to slip my hand under her shirt when my sister barged in.

"Close the door, Derek! I don't need to see you two...doing whatever it is you're doing!" She shouted. I threw myself off of Meredith, but my hand got caught in her shirt and it took a couple of seconds for me to break completely free. Meredith looked mortified, covering her red face with her hands.

"Get out of here, Amelia!" I threw a pillow in her direction.

"It's my house too! And I want to meet Meredith!" I looked back at Meredith from my position next to her and she was sitting up staring at me. "Hi, Meredith!" Amelia approached the bed. "I'm Derek's ofter-overlooked sister, Amelia."

"Hi, Amelia."

"You would think she were 8, what with her attitude, but she's the same age as you." I added in.

"Shut up, DerBer!"

"Yeah, DerBer," Meredith smiled, shoving my lightly with her shoulder. "Don't be mean. Girls know how to get revenge." She directed her next comment to Amelia: "Why don't you go to the same school as Derek?"

"She thinks she's too good for it," I said at the same time as Amelia said "I prefer private school."

"Shush, Derek," Meredith shoved me again. "I want to speak to your sister. I can talk to you later." I huffed and sat back on my bed against the pillows. While Meredith and Amelia bonded, or whatever it was they were doing, I began to think about the benefits of Meredith being friends with my sister.

Girls have sleepovers all the time, right?

"Dinner!" My Mom shouted from the stairs. I wasn't able to even slide off of my bed before Meredith was already going down the hall with Meredith.

Wow...that went well...

I made it to the table to find that my Mom and Amelia had already taken the seats on either side of Meredith. I stopped for a second before just deciding to take the seat opposite Meredith. I pouted in her direction and pushed my chicken around on my plate. She stuck out her bottom lip at me and laughed at something Amelia had said.

"You can go without sitting by her for an hour, can't you DerBer?" Amelia smiled. I looked to Mom's seat to find it empty.

"Shut up," I pouted and begged Meredith with my eyes to come and sit by me. She just smiled and went back to discussing some guy with Amelia. I growled inwardly and ate some corn, spitting it out when I felt something brush my crotch. Hard. I jerked and choked on a few pieces of food. Meredith hadn't even twitched but it was definitely her shoe-less foot resting in my lap.

She didn't do anything else, and eventually brought her foot down from my lap. She stoked my calf gingerly while she exchanged stories with my mother and sister.

When my Mom brought up the time Mark broke my nose, I felt it was time for story time to come to an end.

"Well I hate to intrude on this happy moment but I have some plans with Meredith..." I stood and smiled, practically yanking Meredith back out of her chair.

"She's going to spend the night tonight," Amelia added, smiling at Meredith. "We're gonna be great friends."

"Yep! I might end up liking your sister more than you," Meredith smiled at me and I put my lip out in a pout. She looked from my eyes to my lips and for a second I thought she was going to kiss me, but she backed off instead.

"Well what are we gonna do?" Meredith finally asked as we said goodbye to my Mom and sister.

"I'm...not sure," I laughed. "I just needed you to myself."

"Greed won't get you anywhere, mister Shepherd." She smiled and I grabbed her from behind, wrapping my arms around her waist and lifting her off the ground.

"It'll get me alone time with you," I whispered in her ear before I kissed her cheek and set her down. We laced our fingers together and walked to my car, Meredith swinging our arms high in the air.

I pulled out of my driveway, not even knowing where we were going.

"Where are we going, Derek?" Meredith laughed as I tried to decide which way to turn as we left my neighborhood.

"I really don't know..." I laughed with her. We drove back to her house so she could grab her clothes.

She opened the front door and hopped quickly up the stairs. Assuming that, since Mark's truck wasn't in the driveway, Mark was gone, I followed after her.

"Meredith," I drew out her name. "Hurry! I wanna grope you in my car before we have to go back to my place!" I was joking, of course, but Meredith stepped out of her room wide-eyed.

"What?" I asked uncomfortably. I turned around and Mark was sitting on the couch, just as he had been when we had left. I raised and eyebrow at him and went down the hall to join Meredith.

"I'm timing you, babe." I smiled and tapped my wrist.

"What happens if I'm not fast enough?" She smiled and stopped searching through her closet.

"Then I get to...keep you captive in my room and have my filthy way with you."

"How much time do I have left?"

"Hmmm...about thirty seconds, now." She sat next to me on her bed.

"One," she counted, pressing a kiss to my cheek. "Two," one pressed to my neck. "Three," one to the bade of my neck. My head lolled back at one point as I groaned and I let her count all the way to sixty.

"I thought the cut-off point was at thirty?" I finally asked, running my fingertips down the side of my neck.

"I figured you were distracted enough to let me continue," she smiled and went back to gathering her things.

"I guess this means I get to have my filthy way with you," I said, hopping up from her bed and walking over to her dresser. I inspected her array of colorful lotions and jewelry.

"I guess so," she replied thoughtfully, shoving her clothes into her backpack. She came over to her dresser and swatted my hand away from her earrings. "Don't touch those! You'll get your nasty Derek germs all over them!"

"I'll get my nasty Derek germs all over you," I growled with my teeth barred as I attacked her with kisses and she giggled.

"Promise?" she smiled.

"I swear." I helped her get the rest of her stuff together and then threw the backpack over my shoulder and followed her down the hall. Mark was still reading a book in the living room, but his eyes flicked up and met Meredith's as she turned to go down the stairs. They met mine next and I gave him a quick nod of the head before hurrying down the stairs and out the front door.

"I'm staying at Derek's house tonight, with his sister!" Meredith called. Mark walked over and stood at the top of the stairs.

"You'll want to get home early tomorrow, then," he said.

"Why?"

"Mom's coming home from her big meeting thing down in Nashville."

"Oh damn," Meredith muttered as she looked at me. "This sucks." She turned her attention back to Mark and nodded, letting out a loud sigh. "How long is she coming home for?"

"She has another one in a week."

"Thank God. Okay, well I'll be home around nine, then." Mark nodded and went back to the couch. Meredith pulled the door to and grumbled while we walked to my car.

"Meredith," I laughed. "It's just your Mom; there's no need to get upset."

"Speak for yourself," she narrowed her eyes at me. "You're meeting her tomorrow. As my boyfriend."

I sobered up instantly.

Fast forward a few hours, and I was sitting in the basement watching Paranormal Activity on the big screen. I was clutching a pillow tightly, my legs brought up on the sofa with me. Kate was just yanked off the bed and I was tensing up, preparing for something to lunge out at me when someone wrapped their arms around me from behind and I shrieked like a ten year old girl and threw myself off of the couch. I was shaking when the lights flicked on and Meredith fell off of the couch laughing manically. I tried to catch my breath, lying on my back and trying to calm down.

I think I'm hyperventilating.

Meredith finally stopped laughing enough to gasp for air and she looked over at me with tear in her eyes.

"I could have died!" I shouted and she laughed even harder. "Shouldn't you be with Amelia?" I shouted, pissed that she had heard me scream.

"She's..." she laughed. "She's on the phone with her boyfriend so I came down to see how you were doing." Her laughter finally subsided to bursts of giggles.

Amelia has a boyfriend?

"Well maybe you should just wait for her upstairs," I pouted and hit rewind on the DVD and sat on the opposite side of the couch. When Meredith scooted closer to me, I got up and moved to a chair across the room.

"Oh, Derek stop being a baby and sit by me."

"Nope!" I kept my eyes trained on the screen. I didn't notice Meredith standing until she was right in front of me. She dropped down into my lap, kneeling with her legs on either side of my thighs.

"Please?" She whispered in my ear and pressed several kisses to my jaw. I didn't answer for fear of my voice cracking. I squeezed the remote tight in my hand as Meredith dropped into my lap, resting directly on my half-hard dick. My eyes rolled back into my head when she subtly ground herself against me.

"I guess I can forgive you," I finally muttered.

"Great!" she smiled and slid out of my lap, returning to her previous spot on the couch. I spent a couple of seconds trying to realize what had happened while I thought of some pretty nasty thoughts to get myself...down. I finally moved over next to her and she flipped off the lights.

"That was rude, Ms. Grey."

"But totally necessary," she whispered and pressed play on the remote. The movie started from the beginning and I pulled her into my lap and rested my chin on her shoulder, our temples touching. At one point almost half an hour in, Meredith pulled a blanket over us.

"Cold?" I whispered, nipping her ear.

"A little," she responded, total caught up in the movie. I waited until I knew something scary was about to happen and grabbed her roughly when it did. She squealed and wriggled out of my hard grasp, rubbing against my crotch in the process.

"Stop that!" we said at the same time, her tone annoyed and mine pleading. She looked back at me and smiled, moving her ass again. I groaned and turned her around in my lap, mashing my lips to her quickly. She straddled me again and ground against me. My hands twitched with the need to touch her but I didn't know if she would be okay with that. I finally settled my palms on her ass and squeezed roughly. She moaned into my mouth and ground faster and harder.

"Meredith," I groaned, my hips slamming up into her own. She ran her lips down my neck and bit me-hard- and like the seventeen year old boy I was, I exploded with a loud, drawn out groan. My hips were still thrusting as I tried to calm down.

"Oh Jesus, Mer. That was so fucking hot!"

"Yeah it was," she agreed, looking shocked.

"I definitely need to repay the favor," I waggled my eyebrows and started kissing her again, resting my hand on her stomach.

"Meredith!" Amelia called. We didn't stop. "Meredith I'm sorry I got stuck on the phone! I'm done now!" She came into the living room and looked at us with disgust. I ran my hand up from Meredith's stomach to her ribs just below her boobs. I ran my thumb under her boob, knowing Amelia couldn't see.

Amelia dropped down on the couch next to us and watched the movie.

That's a little awkward.

Meredith didn't exactly seem to mind, so neither did I. I looked at Amelia out of the corner of my eyes and she pretended to stick her finger down her throat before she put her feet up on the coffee table and blocked us from her view with her hand.

Meredith and I made out for what seemed like hours. Amelia kept her hand up, shielding us from her view, the entire time. Meredith drug her lips up and down my neck, probably leaving a hickey or two. I did the same to her and we tried to keep the noise level low. I knew that the second I groaned Amelia would snatch Meredith away complaining about how disgusting I was.

We pulled away for some much-needed air, and I realized it had only been four minutes.

Wow.

Meredith breathed slowly and smiled. I smiled back and ran a finger down her cheek.

"Are you two done yet?" Amelia growled.

"I don't think so..." I muttered as I began again. Meredith giggled, even though she was bright red with embarrassment..

"Oh God," Amelia groaned. The next thing I knew, Meredith was no longer on my lap and I was literally kissing the air. As in my lips and tongue kept moving even though she was gone. Meredith laughed and Amelia watched me like I was eating dog shit or something.

"Where are you going?" I pouted and grabbed for Meredith's hands. Amelia beat me to the punch and pulled her back.

"Meredith and I are going to a party."

"What? Who's?"

"Alex Karev!" Amelia tapped her foot, anxious to leave.

"You know Alex?" Meredith and I asked simultaniously.

"Yeah! He used to go to Brenton. My school." She added for Meredith.

I remembered the say Meredith had come home with Alex Karev, and the awkwardness of me practically ushering him out of the house.

"Think he ever got the message?" I smiled at Meredith. She bit her lip as Amelia pulled her out the front door.

"Wait!" I called. "I feel like I should be responsible and take you guys to this party...watch out for you?"

"No, Derek. We can look out for ourselves!" The weather was starting to get cold and I rubbed my arms to warm them up.

"I won't even hang out with you two. I'll find some people I know! I just worry about you two..."

Amelia rolled her eyes. "Fine. But only if we can take the Lamborghini."

I smiled wickedly. "Okay. But we're parking down the street. Mom will murder me five times over if it even gets a scratch. I motioned for them to follow me back inside. We went out to the garage and I lifted the door. The precious "lambo" sat unscathed inside. Meredith got a look of awe in her eyes and we climbed in. Amelia insisted that Meredith sit up front and crawled in the back.

"Wait," I stopped just before I turned the key in the ignition. "Does Mom know we're going?"

"Yes," Amelia huffed.

"In the lambo?"

"Yep!" She smiled. "You're very predictable, Derber." I shrugged and turned the key. I pulled out of the garage slowly and shut the door.

"Does this car go fast?" Meredith asked timidly. I smiled and shook my head. We turned out of the neighborhood doing eighty.

"Yes, MerBer. It does go fast."

A/N: Well there you have it! I finally forced myself to stop writing. I still have more ideas gnawing their way out of my mind so I'm literally writing the next chapter as I write this.
