Disclaimer: I do not own Life with Derek

IMPORTANT: This takes place one year after Vacation with Derek. BIG NOTE, Nora NEVER got pregnant, therefore there are still only five kids; just Derek, Casey, Edwin, Lizzie and Marti. ALSO notice how Derek and Casey are only a few months apart in age during the show DESPITE the fact that Derek supposedly got held back one grade? Yeah, well that's not fixed, he is officially a year older then her. And if I'm mistaken and he IS a year older than her, ignore this lol.

Title: Decoded

Summary: Sam eyed Derek wearily. "That's not a good idea." "Why?" Tony asked annoyed. Derek scuffed and leaned back on the bed, "Male code, bro. She's my-" "Ex-girlfriend." Sam quickly interrupted. …College life is about to get more interesting, to say the least.

Chapter One

Derek grabbed his fourth beer and idly listened to the thumping of music as the loud beats blared form the surround sound in his Fraternity house at Queens, Phi Kappa Sigma. Already a Sophomore, he enjoyed the pranks of his peers and seniors as they hazed the freshmen, or otherwise more affectionately known as freshmeat.

It was already two weeks into the new school year and they had decided to invite the entire Alpha Delta Pi Sorority so that the Pledges could serve them, wearing nothing but diapers with hilarious small cupid wings attached to their backs while serving alcohol instead of arrows.

As he took another gulp of his beer he smirked as he picked up the conversation about the newest Sorority Pledges, who were here to serve them in return in incredibly short, and incredibly sexy French Maid uniforms. Apparently there was hot talk about one new Pledge sister in particular.

"Dude…" Sam gapped at his side as one of the pledges walked by. Derek could only nod in agreement and let out a low whistle. The pledge smirked and sashayed her hips as she strode by, eating up the attention.

He was glad Sam had came to Queens. He was the only one from their school to attend the same college, minus of course, Casey.

When she had gotten accepted he was sure she would be attending with them, but surprisingly, she had done something so unCasey-like. She had taken the year off, and moved to New York when she had been scouted at her Grandmother's lodge.

He scowled and finished his beer, annoyed at the thought that his keener decided to stop being the grade-grubber and actually did something spontaneous, like accept the deal of lifetime. To top it all off, she had even left with a new love-interest. Jesse. He remembered watching them kiss while he had been with Roxy and immediately ditched his date to tear her away from Jesse to dance with him. The reason for that was, of course, because only he should get to live out the cliché summer fling, who told her she could have one of her own anyway? This wasn't a Dirty Dancing movie parody, he was just making sure it stayed PG… for the kids. …Of course.

When they had finally gotten home she had immediately started packing. He didn't know why, but he didn't want her to go, and they got into a huge fight before she had left. He hadn't heard from her the entire time. Last he heard about her had been from the family and she was still with Jesse and was even considering forgoing school for another year. It had to be the longest relationship she ever held, and he didn't care. Really. He didn't. The year had been quiet, peaceful. Boring.

Another ADP walked by and gave him a wink and he smirked. Okay, maybe not that boring,

"WOOO!"

Both Derek and Sam stepped back as Jack stepped up to them, his cup swaying carelessly as he laughed, thoroughly enjoying himself.

"Yo, you guys see the new ADP pledge, that freshmen's got the body of a goddess!" He took a huge gulp of his drink. "Face isn't so bad either." He wagged his brows.

Sam laughed, "Yeah? Where's she at?"

Jack turned sharply to point her out but before Derek could turn to look as well, Jack splashed a bit of his drink on his shirt and he scowled looking down, not paying attention to the sharp intake of breath Sam took.

"Dude, is that your step-sister?"

Derek's eyes shot up instantly forgetting his shirt and followed their gaze, directly to Casey, and his breath hitched, he gave a panicked look to Sam briefly before turning to Jack.

Jack looked confused, "That's not Lizzie…"

Derek frowned, "Yeah, dude, that's not Lizzie." He spat with a sharp look at his best friend.

Sam rolled his eyes.

Since they started college, as far as anyone was concerned, Derek only had one step-sister. He had never mentioned Casey, and in fact, no one even knew she existed and looking at Casey in that, that… whatever the hell she was wearing, his intended to keep it that way.

She apparently had gotten her dancers body back, before the vacation she had quit dancing and working out and studied all the time and ended up gaining a few pounds. He remembered the part where his snide remark about her weight had come in during their last fight. He scowled as he eyed her up and down.

She had nearly the same body she had had during their senior year. She was incredibly slim, but the extra weight she had packed on had apparently stayed in just the right places. He finished the rest of his drink in one last swing as she twirled around and her hair followed the movement. Looks like it had all grown back to it's original length, and had even more blond highlights than it had held before, the underside was her normal rich chocolate color.

As Jack left, Sam turned on Derek. "Dude you gotta let it go, the fight was like what? A year ago. You can't ignore her forever."

Derek grabbed a drink from a passing pledge's tray and winked before rolling his eyes at Sam. "Yes. I can." He opened the beer and took a swing. "Besides, she's the one ignoring me. Last I heard she wasn't even coming this year. I'm just as surprised as you."

Sam rolled his eyes again, "Well whatever. I'm going to go say hi."

Derek's panic was barely contained before he cursed and followed after him his eyes on Casey. The sleeveless black dress clinging to her curves before flowing out around her hips, the lacy underside just barely able to cover her ass as she walked with her tray of serving beverages in hand.

"Casey!" Sam called out and she turned with a wide smile. When her eyes landed on Derek she frowned for a brief second before a very Derek-like smirk flitted across her lips that took the guys both by surprise.

"Sam, it's so good to see you! I forgot you got accepted here." She said with a giant grin replacing the smirk as she sat the tray on the table an gave him a large hug.

He laughed and his eyes dilated slightly as he took her image in up close. He had never seen her dress this way before. "You're an Alpha Delta Pi Pledge?" He asked with a small smirk.

She smirked right back and did a little twirl in her three inch stiletto heels with a small pop of her hip. "Did the mini-skirt give it away?" She asked flirtatiously before her voice lowered and she spoke in a sultry French accent. "Or did you mistake me for a real maid?"

Sam and Derek's eyebrows both rose at her tone.

Derek quickly regained his composure and sneered with a snide smirk, "Who wouldn't?"

She gave him a brief glare before turning to reach for her tray. She was under strict orders as a pledge to tolerate all the frat boys and to be nothing but nice. Bending to pick it up, she made sure to turn her back to them as she kept her legs straight as she reached down, watching them out of the corner of her eyes at exactly where their eyes traveled to before turning back and offering the tray which held the drinks. Giving Derek a sickeningly sweet smile she held it out to him, "May I offer you a beer, Master."

Derek frowned. He forgot that the pledges had to call them Master. Grabbing the beer, he smirked. Oh the fun. "After that little show, beer is all you're going to serve?" He asked darkly, "Oh wait, that's right, you're prude. My mistake." His eyes were intent on hers and smirked as she flushed but faltered when that damn smirk once again braced her own features.

She moved to walk past them, putting one hand on Sam as he went to speak while Derek remained still head tilted back sipping his newest beer as she moved past him.

"It's been over a year since we last talked, a lot's changed, and that's just one of those changes." She whispered into Derek's ear as she passed.

Derek had been in the middle of gulping his beer as she spoke and as she walked away with her last sentence he spit out the beer and turned to look at her shocked.

"Dude! What the hell?" Sam frowned, looking down at his shirt which had gotten slightly sprayed as Derek had turned his head like the exorcist.

Derek watched as her hips swayed as she walked, and frowned. "Hold that thought." He called behind him to Sam as he followed Casey, taking her by the shoulders and guiding her away from his frat brothers which were currently ogling her and leading her to a quiet area by the staircase.

"What the hell was that?" Derek spat, eyes dark.

Casey smiled at him coolly, unfazed. "What was what?" She asked in a sickeningly sweet innocent way.

He put his hand on the wall beside her and leaned down to her face, glad he had grown the few inches he had for the added intimidation factor as he leaned over her. "You know what. What's gotten into you."

Casey held her now empty tray to her chest and looked around to make sure her senior Sorority sisters weren't around since part of the haze was that her tray was to never be caught empty or she'd get a penalty. Looking up at Derek she gave him a glare. "I don't know what you're talking about."

Derek barked out a short laugh and leaned closer to her, his eyes dark. "Oh really? Since when do you wear…" His eyes trailed her body slowly as he paused before slowly dragging his eyes back up her body to her eyes, "Maid costumes and act like that."

"In case you didn't notice, although not surprisingly considering how slow you are, this is apart of the haze and since I'm a pledge…" She trailed off with a smirk.

"Say's the freshmeat," Derek growled and smirked right back, "Don't forget, I'm a sophomore, your upper classman."

Casey gave a sharp gasp of mock surprise and pat her hand on his chest in a condescending congratulatory way. His eyes darkened further and quickly shot a gaze down to his chest where she kept her hand before looking back up at her as she spoke. "I bet you're so proud too, right? Finally a grade above someone whose younger than you." She gave mock sympathetic sigh, "Oh wait, that's right, you're still older than most of your peers. Well, at least you got one up on me."

Derek growled and took a step closer to her, their toes touching now as he leaned in closer. "You're one to talk, you took a year off remember? You're walking in dangerous territory princess. I'd advise you to stop pissing me off. Cut the act."

She smirked at him again and his eyes narrowed. "What act?"

"Aren't you a bit prudish to come off as the mean Sorority sister, sister?" Derek ground out, remembering her words from earlier. "Or wait, did the virginal princess finally get laid. I see Jesse getting you into the sack didn't rid you of your bitchiness but the new backbone's a nice touch. Were you trying to give the whole room a view of it since you're so proud of it? Guess you're not just the mean Sorority sister, huh, how about slutty Sorority sister?"

Casey's smirk quickly fled from her face and a flash of hurt crossed her features before her face went blank and Derek's eyes lost a bit of their heat as his brows cinched together briefly. Even he knew that was pretty low.

"PLEDGE!" They both turned to the right to see the President of Alpha Delta Pi glaring at Casey. Derek remembered her from another party and smirked. Cindy. "No drinks on your tray? Penalty. You know the rules. We'll be waiting in the living room." She cast an identical smirk at Derek and Casey frowned at the looks on their faces as they regarded each other. She walked away with a flip of her shoulder length bleach blond hair and walked away.

Derek turned to look at Casey again when she suddenly leaned up to his ear and her hot breath made him freeze. "What makes you so sure it was Jesse?"

She ducked under his arm and made a move to walk away when he went to grab her arm and pull her back, suddenly furious and no idea why when a group headed to the living room separated him from her allowing her escape. He cursed as he tried to make his way through the crowd.

When he got to the front of the crowd he ended up by Sam as a few of the pledges from the fraternity and sorority stood before everyone.

Seeing Casey in the lineup he realized what was happening.

Cindy and Tony, the Phi Kappa Sigma President, looked around the room and smirked at each other before looking at the guilty faced pledges. "You know the rules of the haze. The point of tonight's hazing was to serve your superiors all night long, so those of you who were spotted with empty trays will have to pay the penalty or be forced to resign from Pledging."

A few hoots and hollers went around the room at the news. Everyone loved it when a pledge failed to please, it meant seeing an entertaining show of embarrassment for the pledges.

Tony started to speak. "Since our pledges failed to serve, you'll have to make it up to your Mistress, President of the Alpha Delta Pi, Cindy Crooner."

The three pledge failures eyes perked up at the news.

Cindy smirked. "Same to our little Maids. Make it up to your Master. Tony Morrelli."

"Okay Cupid cuties, line up in front of me to receive your punishment." They immediately did as she told.

Tony ordered the two Maid's, Casey and some other girl in front of her Derek barely recognized as Jane from earlier in the night and he felt his stomach drop. For some reason, he didn't like what was happening, and he didn't even know what was happening.

"Get on your hands and knees." Cindy crooned.

They fell to the floor.

"And one by one. Crawl to me." Tony ordered with a smirk.

Sam blew out a breath he had been holding and nudged Derek. Derek looked to his left where he saw some of his Frat buddies eyeing the spectacle of the circle they formed around the show and realized what they were looking at.

On their hands and knees the maid costume's already incredibly short skirt was short enough to give them an extra show.

A few began to whistle and he made a move to stop everything when Sam put a hand on his shoulder and held him back. "Dude if you stop them Casey won't get into the Sorority, and she'll never talk to you again. Besides she chose this."

"She hasn't talked to me for a year, and I should care now why?" Derek spat ready to shove him off.

Sam gave him an annoyed exasperated look, "We're only Sophomores, we can get kicked out, and it sure as hell didn't look like you guys weren't on talking terms ten minutes ago."

Derek blanched and ignored the questioning implication of Sam's last statement and chose to raise a brow instead. "What do you mean we?"

Sam rolled his eyes, "If you start a fight, I'd have to step in and get your back. Best buds right?"

Derek grinned, his dark look from earlier almost gone, "Right."

"So don't fuck it up for me."

Derek looked surprised for a second before nodding. He turned to look at the show again, biting the inside of his cheek as he watched the first pledges make it to their masters feet.

"Kiss my feet." The two Presidents ordered simultaneously.

Derek ignored his Frat's pledges as he eyed Jane kiss Tony's shoes, and frowned as the presidents ordered them to kiss their way up their masters until they were told to go back to their respective dorms as they were no longer allowed to stay at the party for their disobedience. Derek scuffed.

Tony stopped Jane at his stomach, the poor girl was ridiculously red in the face and slightly shaking. As she was ordered back to her dorm room, Derek went frigid as he realized it was Casey's turn.

She bent low and kissed his feet already on her hands and knees and Derek's eyes narrowed and his fists clenched as he heard the whistles from the sideline returning.

She rose to her knees as she slowly kissed her way up his jean's pant leg, stopping for a second as she came face to face with his belt buckle, where Jane had been ordered to kiss and was told to stop when she started having her freak out.

Sam took an intake of breath as they watched Casey's face. She looked completely calm, they had expected her to be the same mess as Jane or worse but instead, to their surprise, and Derek's annoyance, that smirk came back and she looked up and Tony's equally smirking face as she kissed his belt buckle and kept eye contact as she did it.

Tony's smirk only widened, and instead of ordering her to stop as he did Jane he has her continue. "Kiss my stomach."

She did. Derek's knuckles turned white.

"Kiss my shoulder." She was finally on her feet now, at last, as she kissed his shoulder.

"Kiss my neck." She did and looked into his face, her eyes cautious now as she realized he probably didn't intend to stop, as Cindy had done with one of the pledges, he intended to make her kiss him on the lips.

"Kiss me." She looked left and then to the right and spotted Derek and Sam eyeing her intently with baited breath's. Sam looked slightly concerned and Derek looked pissed as he glared at her, as if to tell her to stop. She frowned and turned back to Tony, planting one squarely on his lips.

The rules were simple, the Master's and Mistresses were allowed to look, but not touch. Cindy hadn't touched the frat pledges as they kissed her, but Tony decided to break the rules as the last frat pledge was ordered to his room and Tony put his arms around Casey's tiny waist and bent over her, kissing her like there was no tomorrow.

Catcalls and whistles flew around the room at their daring Frat president before Derek moved to step forward as he noticed Casey's hands on Tony's shoulders trying to push him away when Cindy suddenly pulled them apart and glared at Tony.

"Shame shame. You broke the rules." Cindy called, as if to make a show for everyone. "On your knees."

Derek let out a breath of air, glad it was over and Casey was going to get sent to her dorm and smirked at Tony's predicament.

Tony smirked. "Oh, do I get punished now?"

Cindy smirked back and put her arm around Casey. "For breaking the no touch rule? Definitely." She gave a slightly annoyed look at Casey, before sighing. "Since you betrayed your servants privacy, she gets to stay."

Derek scowled and he distantly felt Sam pat his shoulder.

Tony shrugged and Cindy glared. "Kiss my feet and don't stop until I say so."

The crowed oohed and awwed. Derek had to admit, the girl had balls.

Tony kissed her feet for what was probably 10 minutes before an annoyed expression started to grace his face, and as he was about to get up, Cindy told him to stop and he was done before he could regain his own dignity.

After that the party started to die down and Derek went on a mission to find where Cindy had dragged Casey to but it appeared that they had already went back to the Sorority house before he could corner Casey again.

He groaned and grabbed his 10th beer of the night and swung the beverage down before Sam laughed at him. "Dude, what's the deal?" as they headed to their room upstairs.

Derek didn't even look at him as he flopped down on his bed. Voice muffled by his comforter his face was planted on he responded. "No dice, no deal."

"I meant about Casey."

Derek didn't lift his head up but he turned his head to the side. He was about to talk when they heard Tony at their door.

"What about Casey?" He smirked at them and Derek sat up on his bed, annoyed. "That hot new Fresh?" His eyes looked far off, "She sure is something, eh? I think I might try for her next."

Sam eyed Derek wearily. "That's not a good idea."

"Why?" Tony asked annoyed.

Derek scuffed and leaned back on the bed, "Male code, bro. She's my-"

"Ex-girlfriend." Sam quickly interrupted and Derek sent him a surprised look that quickly turned to annoyed as he seemed to ask what the hell Sam thought he was doing with his expression.

Tony looked at Derek surprised. "You know her?"

Sam replied before Derek could and it was beginning to annoy both Derek and Tony. "Yeah, we went to high school with her for four years. They were pretty serious too. Derek's still got a thing for her so..."

"Sam." Derek spit out darkly.

Tony chuckled and raised his hands. "Nah dude it's cool, I get it. I remember when I laid down the law with you last year about Sheena. I'll back off…" He trailed but gave Derek a leveled smirk. "But if you decide you want Sheena again, go for it but remember I get to nail Casey if you do."

Derek glared at the way he wagged his brows and his tone when he said nail.

Tony chuckled before closing the door and walking off.

After they heard his footsteps disappear up to the third floor Derek turned on Sam, "Dude what the fuck?"

Sam sighed and laid down, lifting up on one elbow he gave Derek a tired look, "Dude he wouldn't have gave a shit that she's your step-sister and you know it. At least this way he'll back off…" Sam trailed off lightly. "For a little while at least."

Derek threw a pillow at him as he laid down and closed his eyes. "Okay number 1, she IS my step sister so… ew. And number 2, why should I care whether or not he wants to nail her." He glared darkly as his conversation with Casey flashed through his mind. "Besides, it's not like she's a virgin anymore, and she seemed pretty damn okay kissing her way up his body." Derek shuddered in disgust and rolled over, closing his eyes, annoyed when he felt the pillow he threw at Sam hit him in the face.

"Oh please, for someone who doesn't care you sure seem too… and how'd you know she's not a virgin anymore?" Sam asked curiously. His eyes lit up, "Is this why you guys were talking all covert by the stairs earlier?"

Derek glared at him. "I don't care, she's just my stupid sister and yeah, she basically just came out and said it too me."

Sam smirked, "Funny, that's not a topic me and my sisters ever talk about. Kinda awkward really, but then again, you guys never acted like brother and sister before."

Derek frowned, "What's that supposed to even mean?"

"Dude, ever since she moved into your house there's been this annoying sexual tension thing that everyone could see right through." he paused for effect, "Well, except you and Casey anyway."

Derek flopped down and rolled his eyes. He wasn't that dense, he had felt it from the moment she had walked into his life despite how much he tried to ignore it. "Whatever."

Sam smirked and laid down as well, "Hey, it's not like anyone beside me knows about your situation. As far as anyone concerned on Campus everyone thinks you only have one step-sister, and as far as Casey's concerned, she'd like to keep it that way."

Derek tried to sound uncaring, "Oh? And she told you this herself did she?"

"Yeah, I told her about it and she had no problem with it." Sam started, "Hey maybe she won't even mind pretending to be your ex, especially since she has no problem telling you all about her sex life and getting all cozy with you tonight."

Derek growled, "We weren't cozy." He frowned, "Just, shut up. Sleepy time, okay?"

"Yeah, sure, whatever you say buddy."

Derek threw the pillow at him again and Sam laughed.

So what did you think? Should I continue?
