One of two updates that'll be coming your way! I hope you like it!

D POV

I slipped into Meredith's house and yawned as I stepped into Mark's room. Meredith had woken me up at five that morning and pushed me out the door without a kiss good-bye. By the time I dragged myself into my own house, I was too awake to even bother going back to sleep. I stifled yet another yawn as Mark beckoned me over to play Halo.

"Hey, man, why so tired?" he asked, "Find you a nice girl to keep you up all night?" Even though I knew he was joking, my face flushed in embarrassment.

"Nah…" I muttered, thinking about how nice it was to fall asleep with Meredith tucked in my arms.

"Pfft. Liar, get your ass over here and help me beat this fucker."

I rolled my eyes and threw myself next to him on the couch, grabbing a controller in the process. I knew I'd be no help to Mark; I was way too busy thinking about his sister.

M POV

Around 11 that night, Derek sauntered into my bedroom, looking like his usual cocky self.

"Derek! What're you doing!?" I asked as he pressed his lips to mine quickly.

"Mark is in the shower. Don't worry!" he pressed his lips to mine again, more forcefully this time, pushing me down on the bed behind us.

D POV

I dove on top of her and continued sucking gently on her neck. When my teeth made contact with her pulse point, she pushed me back.

"What?" I asked, only slightly hurt.

"No marking the neck," she said sternly. "Mark's seen me once today, bruise-less, and if he sees me with a bruise….well lets just say he'll know he didn't do it…"

I sighed, "You have a point, I guess."

"I do!"

"How about something a little more subtle?" I asked, an idea rapidly forming in my brain.

I jumped up and walked over to her desk in search of a marker.

"Aha!" I held up the Crayola pen in victory and made my way back to Meredith. I pulled her arm into my lap and went to work, telling her not to look until I finished.

"Okay, you can look now," I smiled.

"Derek!" she whisper-shouted, "I can't believe you!" she hit my chest for emphasis, so I grabbed her hand and ran my lips across her knuckles, effectively quieting her.

"Hello, my name is Meredith and I belong to Derek Shepherd." I read aloud.

"Derek! I don't belong to anyone!" She hissed, "What would you do if I treated you like you were…a bike or a car?!"

"I'd let you ride me all night long" I whispered seductively in her ear and smiled when she let out an involuntary whimper.

"Very…very funny, now help me get this," she gestured to my graffiti, "off of my arm!"

"But I like it" I whispered. I began kissing her neck, moving up to gently suck on her earlobe. I knew how it undid her when I kissed her neck, though she tried denying it.

"Derek…unhh…you have to…" I stopped before she could finish, having heard the shower shut off.

"Bye, babe!" I smiled, watching her try to compose herself. I pulled her after me as I quickly walked to the door. Kissing her chastely, vowing not to get too caught up in the kiss, I stepped back and gave her a signature smile before walking out the door. Then, I remembered something.

I ran back to her doorway, where she was still leaning and bent in to kiss her again. However, rather than kiss her, I went at her neck and nipped her lightly. Enough to leave a mark,- but a mark small enough to go unnoticed by her brother. After all, he'd have my ass if he knew.

She reached up to cover the bruise, and hissed, "Derek! I can't believe you did that!"

"Night, honey!" I chuckled as I sauntered down the stairs towards Mark's room.

M POV

A couple of hours later, I woke up to the sound of someone walking down the hallways towards my bedroom. Unsurprisingly, Derek popped his head in seconds later.

I feigned anger, and shot a glare in his direction.

"Oh if looks could kill!" He laughed and stepped over to my bed. He threw himself to the middle of my bed with his back against the headboard and pulled me onto his lap.

"You're lucky I'm not that mad about this anymore," I pouted.

"Oh yeah, I'd be in major trouble if you were!" he said. Sarcastic ass.

"Sarcastic ass…" I voiced my thoughts, emphasizing my words with a light slap to his chest.

He scrunched his nose briefly at my words and leaned in to kiss my nose.

"I thought you liked my ass…" he let his bottom lip slip out and looked to the ground.

"You know I do," I purred into his ear. "And I happen to like other parts of your anatomy too…but those will remain nameless."

I immediately felt his length harden against my thigh, so I bit his ear for good measure. It lengthened more and I grinned against his neck.

"Like that, baby?" I purred again. He did nothing but moan in response. He slid down the bed so that he was lying flat on his back, with me still sitting on top of him. I ran my hand back and forth slowly over his zipper, pressing every few second and his hips thrust in the air.

"Oh…God Mer. No….unnnhhhh…If you…" he gasped for air as I gently palmed his member. "Don't stop, I can't….I won't be able to uughh!" he began thrusting his hips again.

I slid off of him and lay at his side, resting my cheek on his toned chest. He continued to try and regain his control. He finally wrapped an arm around my waist and looked to the ceiling.

"Mer, honey, If you do something like that again, don't expect me to stop." He chuckled.

"I mean…If Mark weren't asleep right downstairs…God would I have turned over and-" he stopped talking and closed his eyes.

He finally re-opened them and turned over to kiss me.

"Stay here, at least until I fall asleep," I pleaded, desperate for more time with him.

"Okay," he murmured soothingly into my hair and rubbed my lower back slowly, lulling me to sleep.

D POV

The worst way I've ever been woken up was by Mark when we were eight. He threw cold water in my face. Once again, Mark was awakening me, but this time we were older. This time…he was pissed off.

He pulled me over Meredith and out of the bed, holding me up by the collar of my shirt. Somewhere in the distance, I could hear Meredith shouting at Mark to put me down, but I could only focus on the pure heat and anger radiating off of him. His jaw clenched and unclenched as he threw cuss words into the air like it was nothing.

"You stupid fucker! I'll castrate you!" were the last words I heard as my head cracked against the wall behind me.

Hell hath no fury.

So??? How'd you like it? Leave me love!!!
