Author's Note: Yes, I know I have another LWD fic already in progress. But this just had to come out I guess. lol. A Christmas Derek/Casey story... most likely just a one-shot. Hope you enjoy and happy holidays!


Mistletoe.

I never understood why the people standing under it had to kiss. It just didn't make sense to me. It was just a stupid plant.

A stupid plant that completely turned my world around less than an hour ago.

Let me explain. You see, with my mother remarried and us with a new family, George and Mom wanted to have a big Christmas party this year, our first major holiday together. So they invited some friends and neighbors for a celebration on Christmas Eve. The house was decorated wonderfully, thanks to Mom, Lizzie, and I. Christmas carols were playing softly in the background, and people were all over the place, chatting, laughing, and basically having a grand old time.

Me, I was pretty bored.

Lizzie, Edwin, and Marti were playing some Christmas game, and there's was nobody really that was my age around. Except, of course, Derek.

Derek, my conceited, arrogant, annoying stepbrother. He was sitting in the corner very sloppily, his tie undone and top buttons unbuttoned on his shirt. He had messed up his hair, and it was sticking out in every direction now. He looked extremely disinterested in the party, his fingers tapping to his own inaudible tune as he listened to his iPod.

For lack of anything better to do, I walked over to him. He looked up at me curiously.

"Not having a jolly Christmas Eve, Case?" he asked, taking out one earphone.

I sighed heavily, my eyes scanning the room. "Can't say I am."

Mom walked over to us, her face bright with happiness. At least someone was enjoying the party. "Hey kids," she said, her smile overpowering. "Would you mind getting some more appetizers in the kitchen? They're right in the fridge."

"Sure," I replied and Derek mumbled something but stood up. We went through a maze of people clad in various shades of red and green, and walked into the empty kitchen. It was nice to get away from everyone.

Of course, stupid Derek was in the room too, but it was better than being in the crowd of eggnog drinkers.

Derek passed me one of the appetizer trays in the fridge, and we both took off the saran wrap, revealing stuffed mushrooms and some other type of hors d'oeuvres.

"Man, this stuff reeks," Derek swiped a hand over his nose in disgust, staring down at his tray of unknown appetizer.

I moved closer to him and made a face, trying to distinguish what exactly it was. The door swung open and Derek and I both turned.

"Smerek!" Marti giggled, doing a little dance in the bright orange dress she had insisted on wearing.

"Hey, Smarti," Derek said to his little sister. "You hungry?"

I gave him a Look. "Don't feed her that, Derek, we don't know what it is."

Derek just shrugged. He was about to retort something back when Marti gave a loud laugh. We looked back over at her, wondering what she was cackling about.

"Smerek and Casey are under the mistletoe!" she covered her mouth to stop herself from laughing, looking quite amused.

Derek and I both looked up above us in sync. Marti was right. Apparently, someone had the bright idea to put mistletoe above the kitchen sink.

"You have to kiss!" Marti pranced around the room. She stopped and looked up at us expectantly. "Kiss!" she practically demanded.

Derek smirked over at me. "The kid's right, Case. It's the rule."

"Well, it's a stupid rule. I'm not going to—" before I had the chance to even finish my sentence, Derek shocked me by crushing his lips against mine. I didn't have time to think as he placed his hands on my waist, pulling me closer to him. I felt his tongue against my lips, begging me for entrance.

And, caught up in the moment, I let him in.

My arms instinctively wrapped around his neck as his tongue caressed my own, causing my mind to whirl. My eyes fluttered shut as the kiss deepened, and I involuntarily moaned in pleasure.

"Smarti, go see what Edwin is up to," Derek gasped against my lips. I looked up at him through my eyelashes and saw his hungry look.

"Okay, Smerek!" Marti said in a sing-song voice and we heard her exit the room.

Derek growled then, picking me up and perching me on to the edge of the sink so we were now eye-to-eye. I wrapped my legs around his waist and arched my back as I felt his wet, hot lips against my throat. He trailed scorching kisses down my neck and I buried one hand in his thick, messy hair. I was surprised at how soft it was.

"Mmmuhhh…" I moaned again as his lips captured my own again. I felt one hand sneak up the front of my shirt and cup a lacey-bra-covered breast. The heat of his hand made me gasp.

He groaned as our tongues dueled. I had never felt anything like this before. And the one giving me so much pleasure was…Derek.

Annoying Derek. Conceited Derek. Stepbrother Derek.

He pulled away from me and grinned against my lips, as if hearing my own thoughts.

"Merry Christmas, Case," he smirked, licking his lips, and took off, leaving me sitting on the edge of the sink, confused, flushed, and completely bewildered.

Damn mistletoe.
