Chapter 5:
Sober Sister

"Where are you guys going?" Derek questioned his hockey buddies, who were getting dressed in the locker room after practice. Normally jeans and t-shirt were the norm, but today a few of his buddies were dressing up a bit more; slacks and button downs...just like him. Interesting.

"Some Greek party," Jason replied, toweling off his wet hair.

"You're going too?" Derek asked as he buttoned up his own black shirt.

"Yeah. Ever since you started dating Casey, her sisters have been at our games and practices." Matt replied, it sounded like he was going too.

"So you guys fell for sorority girls?" Derek laughed. He never would have thought it would actually work.

"Hey! We're just getting to know them. You're the one that's in love with one! Plus you keep going on about how different she is. Can you blame us for trying?" Jason defended.

Derek nodded. It was a valid excuse. "Alright, I guess I'll see you guys there." He said as he was heading out.

Jason and Matt grinned at each other as Derek walked out. "He didn't deny it," Matt pointed out.

"And I'M NOT IN LOVE WITH HER!" He yelled as he peeked his head back into the locker room. The boys erupted in laughter.

"You look...alright," he said when she slid into the passenger seat of the Prince.

"Just alright?" She asked, buckling up. She wore a simple little black dress, pumps and her hair was in curls. Being just a pledge she couldn't outshine the rest of the girls, but Derek thought she did a good job at it anyway.

"Ehh, you could've worn a shorter dress," he said skimming her bare thigh with his fingertips.

"Someone's getting touchy-feely," she smiled, brushing his hand away.

"What, am I not allowed to touch my girlfriend?" He asked with a smirk and air quotes around the word girlfriend.

She rolled her eyes. "Girlfriend, huh?"

"Well, I haven't gotten any action in about a month, thanks to you. So yeah, that's as much commitment any girl can expect from me," he shrugged, suddenly a little serious.

"So I got you to settle down, huh?" She laughed. "Who would of thought?"

"Shut up," he laughed with her because he knew that it was true after all.

The party seemed to be at full blast by the time they got there. The music was so loud that they could feel the vibrations from the bass line under their feet. The girls looked pretty, the guys, well you could easily tell which one was a frat and which one wasn't. The frat guys all wore name brand blazers and looked rich unlike the rest of them who worn simple outfits and were most likely riding a scholarship. Poor guys stuck out like sore thumbs, but that's what you get when you bring a few hockey players into a Greek event. "You ready?" She asked. He could tell she was a bit on edge.

"Lets knock 'em dead Princess," he said taking her hand and leading her all the way in.

"Casey!" Christina called the second they walked in.

Casey put on the brightest smile she could muster up as she made her way through the crowd, with Derek close behind her. "Hey," she said reaching the Queen. She wore a pretty tight and revealing blood red dress with a pair of killer heels. Casey may not like her very much, but she had to admit, the Queen had style.

"You came," she noted with fake excitement as her eyes brushed over Derek's figure hungrily.

"Of course." Casey replied trying to be as bubbly as possible. Just try to kill my mood Chris. I dare you! She thought.

"Well, just remember, no drinking!" She teased because she thought Casey would be bored to tears there. She's not gonna know what hit her.

Together the couple did rounds, meeting all of Casey's Greek friends until he was properly introduced to everyone who really mattered. "Okay, think you can handle being by yourself while I get us drinks?" She asked him sarcastically.

He stared at her blankly. "Go!" He said pushing her a bit. Why wouldn't he be able to handle it?

And just like clockwork Christina appeared. She was watching and waiting to swoop in and it was only a matter of time before she could corner him. She skimmed her perfectly manicured nails over his shoulder gaining his attention quickly.

"Hey," she said, attempted to bite her lip seductively. Honestly, it's the type of thing he would usually play into, but not tonight, not ever and not with her.

He took her hands off him as if she were contagious. "Must you touch me?" He cringed.

"Why not?" She pouted as if he had just broken her heart.

"I don't get you, Chris." He yelled over the music, practically pinning her against the wall. She rolled her eyes at his melodramatic act.

"What don't you get?" She asked crossing her arms over her chest, pushing the girls up just a bit. (She will stop at nothing.)

"Why can't you just leave Casey alone? I know exactly what you're doing; you're trying to get all your sisters to date the hockey team. If you haven't noticed, Casey already did your dirty work: she got me, and all my friends are talking to your girls! So why keep bothering her?" He asked since this was becoming ridiculous.

Christina smiled up at him placing a hand on his shoulder, trying to charm him. "Because, she's got the only hockey player I want," she whispered, the words pouring out of her lips like liquid. "And I always get what I want Derek."

He shook his head with a smirk, slamming his palm against the wall above her. For a second there she thought that she had broken him down, that she had gotten him to where she needed him.

"I. Don't. Want. You." He hissed. " I'm done trying to explain it to you. I'm here, for her. Only for her. And it would make things so much easier if she wasn't pledging. So Chris, the way I see it, you should be on your knees kissing my ass right now. Because I'm pretty sure I could get her to leave, but I'm not that guy. I don't do the whole 'do as I say' shit. So play nice, ok?" He asked before walking away from her.

"I would do as you say, Derek," he heard her say behind him.

"You really don't take no for an answer, do you?" He asked almost sick to his stomach by the thought.

"I always get what I want," she repeated.

"Not when you're up against me." He said with a look of disgusted.

Just then Casey appeared with two drinks. She handed one to Derek of course, he obviously needed it. He was gonna blow the whole thing if he keep going up against Christina like that.

"I thought you were supposed to be a sober sister?" Christina snarled to the pledge that stood behind Derek.

"Oh, I know. This one's for you," she said with a charming smile. "You're gonna need it." She muttered the last part.

Christina took the cup cautiously as if it would blow up.

"Finish that," Casey demanded, turning her attention to Derek. He eyed her, confusion was evident in his eyes, but did it anyways. He gulped down the contents of his red cup and felt like he needed another, but Casey had another plan. She took the cup out of his hand and pulled him to the dance floor. Oh what a show they were about to give. Poor guy didn't even see what was coming to him.

She dragged him to the center of the madness. She dropped his hand and started moving her hips to the beat of the music. She lost control of her body and let the music embed itself deep into the tissues that made up her every muscle. She made it seem like she didn't even need Derek there at all, and at first she didn't even use him. She just moved to the song, gaining everyone's eyes. What was this pledge doing? They all thought. When she was satisfied with the size of the crowd that had gathered around, she took his hands and pulled him towards her. He definitely wasn't expecting this. He was too concentrated on her.

She leaned into him and he leaned away from her, like magnets that were attracted towards each other but they didn't touch. There was something so sensual about almost touching. So close you can taste it, but not quite there yet. The anticipation of that alone could almost kill you. We always want what we can't have, don't we?

She gave up the game and pulled him forward, tugging on his collar as she leaned back herself. He quickly gripped her hips to steady her, he didn't want her falling backwards. He let one hand slide to her bottom and as he kept the other on the small of her back. She smiled as he caught on. He nodded, urging her to continue with whatever the hell she had planned. She released her hold on him and steadied him back in an upright position. She slowly danced around him, circling him as a hunter would its prey. She eyed him down like she wanted him - no like she needed him. And he watched her every move, his eyes never leaving her body. He looked ridiculous, like a dog chasing its tail, but no one's eyes were on him. At least not yet.

Remembering the dance they practiced back in high school, she spun around in circles, dodging his outstretched zombie like arms which tried to catch her. She suddenly turned around and let herself fall into his grasp. He cradled her neck in his palm as she extended her leg up towards him. With his free hand, he took it gently, caressing her soft skin. He let his fingers trail passed her knee, midway up her thigh before she twisted out of his hold once again.

She danced around him once more before standing in front of him, facing away from him. He brought her hand up to his neck and wrapped his arms around her waist. His free hand skimmed down her body as they started into each other's eyes. Where the hell is this coming from?Both step-siblings thought, yet they didn't question it. Deep down, they've wanted it all along.

You could only wonder where his hand would touch and where it would stop, if it did stop. She caught his hand and wrapped a leg around him. He picked her off the ground gently and spun them around. She pulled out of his grasp and danced, for him, swaying her body in every which way, drawing him towards her. It worked of course, just the way she wanted it to.

From there the choreography was dropped and it was all about instinct, and all she wanted was to be on him; her body to touch his in ways that would make her mother gasp. And that's what it was for the remainder of the song, her body rocked against his. Every move she did, he quickly followed after her. Their faces getting so close, their breaths were reduced to panting, lust spelled out with their bodies. Yes, it was intense…..and that was only one song. Now imagine the rest of the night.

Seeing them dance like that (practically sex on the dance floor) made Christina lose it. Once they started she needed a few more drinks in her, just to be able to stand the pair. She knew she was drinking too fast and that if she didn't want to go home just yet she had to stop, but she couldn't help it. Seeing Casey's hands all over Derek's body and the way Derek held her body so possessively, she couldn't take it.

What did Casey McDonald have that she didn't? Many things, a normal person would answer, but Christina saw nothing. Of course she could have another guy, but what was the fun in getting something that already wants you? See, she loved the chase, and Derek - well he was the most exciting chase she had seen in a long time, and choosing a pledge over her? Well that just made it just a bit better. The harder he pushed, the harder she'd fight back. She was determined to get him least once. The second she did, he could go back to Casey if he wanted. But right now she was going to get him.

"Casey..." came a small call from Christina. She looked ready to go. It was a surprise really how that girl was still standing.

"Time to go?" He asked Casey, placing a hand on the small of her back. She didn't want to go, she was having so much fun, but it was time for phase two after all. She nodded sadly running to Christina's aid, helping her walk towards the car.

Casey guided Christina up the steps of the house but didn't go in. She turned to Derek, who was leaning against the stairs with his hands in his pockets. She walked over to him slowly, looking into his brown eyes.

"Hey," she whispered.

"Hey," he whispered back. They could almost feel Christina roll her eyes at them from the top of the stairs, but they couldn't blow their cover now. This was serious.

Derek pulled her close to him, letting his hands slide down her sides and rest at her waist. Casey hid her face in his neck, breathing in his scent. He always seemed to smell like fresh laundry, something that surprised her. She placed feather light kisses up his neck until she reached his jaw. She slowly lowered her gaze from his eyes to his lips. She never really noticed the perfection that was held there.

Suddenly she really wanted this. Not just to piss Christina off, but for herself. She traced his bottom lip with her thumb as she slowly leaned towards him, until her lips hovered only centimeters away from his. Derek closed the gap quickly, not being able to put up with Casey's teasing. Wasn't the dancing enough?

And so they kissed for the first time. It was a small delicate kiss. A simple brush of the lip really. But when they pulled back and looked into each other eyes, they felt it.

He brought a hand up towards her cheek, bringing her lips back to his. She lost her fingers in his hair, pulling him down as well. They were hungry for each other. They battled for dominance, as the urge to reach every single spot with a brush of a tongue intensified. And yes, there was biting. It was everything they had been feeling for years now poured into one perfect kiss; the kind of kiss that left you weak and breathless. I guess it was a good thing he was holding her up. (We know what a klutz Casey can be.)

Then they were interrupted by the sounds of Christina hurling. "Oh, don't worry about me, I'm fine!" She muttered sarcastically before she up-chucked half the contents of her stomach.

"I don't want you to leave." Casey whispered to him, loud enough for Christina to hear, of course.

"Me either," he said leaning his forehead against her. It was suddenly hard to concentrate on anything other than Casey's cherry lips.

"Well…You could always stay." She said smiling up at him.

"House rule: guys can't sleep over!" Christina yelled from doorway, she didn't want to leave those two alone for a minute. Plus, wasn't Casey supposed to be the sober sister looking out for her?

"I never said anything about sleeping," Casey said winking at her big sister.

Her words alone were enough to push Christina back to the edge, barfing up the remains in her stomach.

Casey McDonald you are good, Derek thought. "Sounds good," he smirked.

She set him up in the living room, playing Call of Duty. He had been eyeing that game since the first day he stepped into the house, but he never stayed long enough to actually play. Casey on the other hand was dealing with the Queen: cleaning her up and making sure she was tucked into bed with a bucket next to her, just in case.

"We'll stay for a while to make sure she's okay. Then we'll get out of here," she reported before climbing into Derek's lap. Their new position made it a bit harder for Derek to play, of course. His arms were holding the controller around her frame, while Casey was snuggled up into the warmth of his chest. He was tempted to just shut it off and take a nap, but he couldn't. House rules after all. And he didn't have the heart to wake her up when she finally did doze off. He tried to keep his eyes focused on the flat screen but eventually his vision started to blur. He was going to fall asleep soon.

"Princess," he whispered into her ear.

"Hmm?" She responded, hugging his body tighter.

"I just got a 21 kill streak!" He whispered back with excitement.

She opened her eyes and glared at him. "You really woke me up to tell me that?" She asked annoyed.

Just because they were "together" didn't mean he couldn't tease her. What would the world be if he stopped?

"I gotta get out of here Case. I'm falling asleep," he admitted turning the game off.

"Alright, lets go." She said getting off of him. He didn't like it, but he shook the feeling off, as he got up as well. It was 3 am, he should at least try to get some sleep if making it to class the next morning was even an option.

Casey gathered up her belongings and checked on the Queen; she was out like a light. Casey tiptoed out of her room and made it to the Prince.

"Where to?" He asked because he really wasn't sure. Was she sleeping over or was he? She did ask him how he felt about staying over the night before...

"My dorm's closer," she shrugged. That didn't exactly answer his question though. He pulled up to her dorm and killed the engine waiting for her to make a move - or not.

She unbuckled her seat belt and turned to him. "What?" She asked confused.

"Good night?" He said, sounding more like a question.

She rolled her eyes. Did she have to do everything around here? "Come on," she said sliding out of the car.

He smirked, because yes, he was just invited to stay the night.

AN:Ok, so I'm really sorry this is late guys. But it has been a hectic week for me and I've been trying to make the chapter good cause it was Casey feisty side and what not. So bear with me? I struggled with the Kiss scenes and the dancing scenes. Most of the dance came from the time they danced in the competition (I'm sorry i forgot the episode) and a small part was from Dirty Dancing. So... how'd it turn out?
