Hey! So technically this isn't my first fanfic, but I deleted my first one bc it was terrible, so I thought a new story would be better!

Disclaimer: I do not own Life with Derek

Chapter One

"Derek!" Casey yelled upstairs, "Hurry up if you want my help! I have plans tonight!"

"I'm coming..." Derek grumbled from the top of the stairs.

He walked down into what he thought was his family room-but it was now transformed into a dance floor.

"What is all of this?" He asked in confusion.

"Well, I figured, if you're going to learn to dance, why not go all out?!" She said happily.

"Okay, lets just get this over with."

"Okay, but real quick, why do you want to learn so bad?"

"Geez, Case, I told you already: I want to impress Sally!" He said without making eye contact.

She looked at him skeptically, "I don't believe one bit Mr. Venturi."

He tried to look all tough and said "Yeah, well I have my reasons."

She rolled her eyes and they began to dance.

"Wow, this really isn't that hard." Derek said.

"Yeah, because I'm leading you! Come on Derek, be a ma-DAMN! Stop stepping on my toes!"

"Sorry." He said laughing.

They finished dancing and sat down on the couch with glasses of water.

"Wow, now I'm as straight as they come, but I never knew dancing could be that much fun."

"Haha, yeah, so could you tell me why you wanted to learn?" She said laughing.

"Hmm, maybe when you're older." He said sighing and heading upstairs.

She sighed and returned to her water. Before she knew it she heard someone calling her name.

"Case...Space Case...Klutzilla..."

"Huh?" She said as she sat up.

"Nora and my dad went out to dinner, Lizzie and Edwin are sleeping over at friends' houses, and Marti is at my moms house...so they left us money for dinner, what do you want?"

"Wow, you're actually asking me what I want? This is definitely a first from you! Wait, let me just take a mental video of this moment," she closed her eyes to remember the moment.

"Okay, drama queen, if you don't decide I'll decide for you."

"Hmmmm, Chinese!"

"Okay, I guess I'll just order the usual." And with that he left to get the phone.

"...Yeah, two orders of sweet and sour chicken, one order of orange chicken, two orders of general tso's chicken, and four egg rolls...mhmm delivery please...okay, thanks."

"Geez, Derek, you ordered enough to feed like, 4 Chinese families."

"What can I say, I'm a hungry man...get it! Like the meals you can buy at the store!"

"Wow, really funny, Derek." I said glancing up from my book to watch him laugh at himself.

Within no time, the food was here.

"Mmmmm, it smells so good!" Casey inhaled.

Derek got the plates and silverware, and Casey got the drinks.

"Hmm, okay, so ya wanna do something fun?" Derek said with a fiery look in his eyes.

"What do you have in mind?" Casey asked as he cocked his eyebrow.

"Well, our parents probably won't be back for awhile, and I'm feeling a tense, so how about something to loosen us up?" He said as he grabbed a bottle of vodka.

Casey thought about this for awhile..."Okay! But no matter what happens, neither of us tell them about this...ever, not even as some sort of blackmail-my mom is really serious about drinking."

"Agreed" He said as he grabbed her hand to shake on it.

It must have been pretty funny to see the two of them, eating a ton of Chinese food with their shots of vodka. And the fact that they were actually acting nice to each other-almost like friends.

Within an hour, they were pretty hammered.

"I...can't...believe...you...dumped...your...coke...on...Kendra!" Derek said in between laughs and shots.

"She wouldn't...leave me...alone...talking about...you!" Casey managed to get out.

The random conversations continued for another 20 minutes.

"This night has been a lot of fun...I've never seen you like this, Case." Derek said staring dreamily into her blue eyes.

"Yeah, I haven't seen you ever being this nice to me." Casey said, returning the stare.

His eyes darted downwards, "I'm really sorry I haven't been nice to you, Case. It's just easier to be mean instead of using your true feelings...I'm not really a bad guy, Case."

"Yeah, I can see that now..." She said, extending her hand to caress his face. The moment to two of them touched she back away, suddenly sobering.

"I'm tired, I'm gonna go to bed, good night, Derek." Casey said as she started to head upstairs. Derek followed into his own room.

As soon as she got upstairs, she turned on the bedroom light. She was about to plot into her bed when she saw something horrifying lying right there in her own bed.

"AHHHH!" Casey shrieked.

A second later, Derek was running into the room, "What's wrong? Ugh, it reeks in here." He slurred.

She just pointed. There was a pile of throw-up right in the middle of her bed.

"Eww! That's so gross."

"Ohmygosh, I think Marti was sleeping in here today when she didn't feel good!"

"That is nasty, just come and sleep in my room."

"Really? Thanks Der."

He walked off into his room when he heard his name, "Der-ek! I forgot to wash my pajamas and all my clothes are stinky! Do you have something I could wear?"

He sighed and said yes.

She smiled and skipped into his room. He was in the process of getting changed, so she decided tap him on the shoulder, "Derek, do you have something for me?"

"Hmm, here's one of my hockey jerseys, it should cover you...I don't think any of my sweat pants would really fit you." He said shrugging.

"Okay, thanks!" She said smiling. He continued to get changed and she climbed into his bed.

He looked over and saw her snuggling against his pillow, in his bed, in his jersey. He couldn't look away. He loved looking at her in his things. Derek knew that he had fallen for her, fallen for her pretty hard.

She looked up at him blinking and laughing, "Are you coming to bed, silly?"

"Oh, I think I'll just sleep on the floor." He said solemnly.

"Don't be silly, there's plenty of room in here for you!"

"Okay, if you say so."

He climbed into bed and turned away from Casey, and Casey then turned towards him and put her head on his shoulder.

"Case?"

"Yeah, Der?"

"Whatcha doin'?"

"Getting comfortable." She said snuggling closer to him.

Soon, she started to kiss the back of his neck.

"Case..." He moaned, and she continued. He flipped over to be facing her and it turned out to be a full-blown make out session with his step-sister in his bed!

Pretty fast, things started to get even more heated. He couldn't control himself and he started to let his hand crawl up the inside of the jersey she was wearing. She moaned and nodded. The jersey came off as well as Derek's boxers and her panties.

A few minutes later, they were both lying there, panting in his bed. Then they just started to laugh.

"I can't believe we just did that," Casey said laughing, "let's do it again!"

"Wait, let me catch my breath!" Derek said panting.

And then they did it all over again, and then fell into a deep, relaxing sleep, only to be awoken by...
