I don't own Life with Derek or the characters in this story but this idea was purely my own.

Warning: THIS IS NOT A CASEY LOVERS STORY. IF YOU LIKE THE CHARACTER CASEY, TURN AWAY!

Summery: He never meant for this to happen…he didn't mean to fall for the wrong girl. Maybe she can help him replace her sister.

XOXOXOX

When Lizzie woke up the next day she was extremely well rested. The past couple days she's had the best sleep since her family moved in. Add in the fact that Derek broke it off with Casey, for her no less (!) she was over the moon. However, after seeing Derek's note last night she knew things were going to be very frustrating for her and she was very conflicted.

On the one hand she was excited for whatever Derek had planned for her, but on the other hand, she knew when it came to games, Derek rarely played fair, he knows exactly what to do to make her putty in his hands and not only that but he ALWAYS won. She only wonders what his prize is. That thought causes a pool of heat in between her thighs and she knows only he will be able to ease her fire.

She jumps out of bed and gets into the shower, planning on taking a cold one, knowing she was going to need it today. Derek might be the King of Lies, but since she's known him, he's never lied to her, and he told her to get ready for today.

When she finishes her biting cold shower, she isn't surprised to see another envelope on her bed. She picks it up with somewhat trembling hands, eager to see what he had planned already.

Today I'm going to tell you more about myself. First off, I've been crazy about you longer than you realize. Secondly, I always imagine how sweet you're lips will be when I finally taste them, so I give you my favorite candy. Enjoy! More to come.

-Always

It was then she noticed that lying innocently under the envelope was a cherry flavored Blow Pop. Her eyes widen for a second as she picks up the lollipop. When she was younger, she remembers eating the candy on many occasions; it wasn't until recently, when her older sister (Perfect Fucking Casey) told her the brand was crude and inappropriate for young ladies to support and made their mom stop buying them. She always thought her sister was overreacting. Looking at the candy now brought nothing but erotic fantasies to her head. This might actually work in her favor.

Lizzie smirks to herself as she thinks of her plan and gets ready for the day.

After about five minutes, she runs downstairs to see Edwin already at the table with her mom, George, and Marti eating a small breakfast, but where was Derek?

"Morning everyone." Lizzie says cheerfully in her favorite deep purple Maxi dress with a green, yellow, and blue design that made her look very free spirited; and the plunging neckline showing the right amount of cleavage was exactly what she needed today. She smiled brightly at them as she takes her seat and starts eating some green grapes.

Everyone repeats the statement sleepily. Wednesdays were always tough on the family, the weekend was so close yet so faraway. Just then they hear Derek running downstairs and Lizzie feels like her heart just stopped.

"That sneaky bastard!" She thinks to herself as she sees Derek walk towards the table in nothing but his black boxer briefs that clung to him like a second skin. She could see the outline of his small but firm ass that she just wanted to hold onto as he's pounding into her. His bare chest was flat and showed his hockey muscles that she knew if (when!) she touched would be as hard as rock. His hair was messy, like he just got out of bed and looked very...very good! This man was pulling out the big guns!

"Overslept." He mumbled with his fake sleepy voice as he sat down next to Liz. She knew her mouth was probably hanging open but how could she not ogle that perfect body that was just inches away from hers!?

"Well eat up quick or you'll make everyone late. Remember Casey is with Emily so I know if you guys are late for school." Nora warns Derek lightly.

She was almost sure she saw her younger daughter staring at her eldest step son, but maybe she was imagining it. She sees Casey do it all the time, but Liz? She's never shown any interest in either of the Venturi boys, but who knows? Maybe something happened with them last night getting ice cream. She reminds herself to look into the two of them, because the question she needs to ask herself is, if Lizzie did have feelings for Derek, should she accept it or put a stop to it? Her and her husband have spoken on numerous occasions on what they would do if Casey and Derek's passion turned to lust instead of hate and they agreed that they would accept them, since they were in their teens when they met and didn't have any blood relation. Lizzie, though she was twelve when she met Derek who was fifteen, so should the same rule apply?

"It's too early to think such deep thoughts." Nora thought to herself shaking her head as she sips more coffee.

As the Venturi and McDonald's breakfast continued, Liz could feel her heart thumping wildly in her chest. This was just unfair, how was she supposed to eat when the God of Canada is sitting next her practically naked and all she wants to do is pounce on him!

All of a sudden she feels his hand on knee. She looks over at him for second, but he's paying her no attention. He's eating his cereal making making loud slurping noises that seem to echo into her ears. Imagining him making those same noises for a completely different reason, along with his hand that is making slowly making it's way higher to her thigh she has to hold back a groan.

When it finally reaches the top of her thigh almost in between her leg, Liz abruptly stands from her chair as she chokes on her grape trying to hold in her moan of pleasure. She can feel his strong hands on her back patting her roughly as she spits out the grape and coughs for a couple seconds.

"Liz are you okay?" Edwin asks her giving her a very strange look. She has been acting so weird lately and he has no idea why. The only thing he does know is that it has to do with Derek and he has every intention of speaking to him soon.

Liz looks at Edwin and nods weakly before looking at Derek who was still rubbing her back.

"I'm fine, just went down the wrong pipe." She lies and gives the table a small smile.

"I think I'm going to finish getting ready. Maybe you should get dressed Derek, we only have ten minutes before school." She points out to him giving him a small glare. Sneaky bastard. She knew he wasn't going to play fair but she underestimated him.

Derek gives her a smirk before nodding. His beautiful girl looked stunning today. That dress was made for her. He can only imagine what the dress would look like pooled around her feet.

"You're right Liz, I think my appetite for breakfast is gone anyway." He replied giving her one last gaze before he ran upstairs to get ready; giving her a perfect view of his perfect blemish free back with his perfect ass.

A minute later she goes upstairs as well to grab her backpack and her phone when she sees Derek text messaged her.

My appetite for food is gone, but my appetite for you will never be fulfilled. Favorite book, Stephen King's The Shining. You look ravishing today by the way.

She was in hell. Today was going to be the sweetest form of torture imaginable.

XOXOX

She will admit, this morning Derek definitely had the upper hand when it came to teasing the other until their desire was so strong they could no longer control it. However, Liz knew when it came to school she would get the upper hand.

You see, she knows that the gossip between Derek and Casey hasn't died down even though Casey has done nothing but glare at him yesterday and she guesses today. They just assume it's a lovers tiff. She also knows no one at the school would think Derek had feelings for HER, when he could have (Perfect Fucking) Casey McDonald.

Therefore when it came down to it, she was invisible to the student population; and she could and would do whatever she needed to do to drive Derek as crazy as he drove her this morning. Without being half naked of course!

At lunch she sat in her usual table with Edwin next to her and of course, Derek within eye sight. She could faintly see Casey sitting with Emily and some of their other friends sitting farther away than they usually do. Casey probably convinced them to move to be away from Derek without causing suspicion.

"So what's going on with you?" Edwin asks bluntly as she takes out her lunch. Voss water with a long straw, a chicken Cesar wrap, strawberries, and of course her lollipop. Perfect. She smiles before looking at her best friend who was still waiting for an answer to his question.

"Ed, you know I love you; you're my best friend, but there are things I don't tell you because I know you wouldn't support me on. Trust me, I'm fine, I'm great actually. Please, just let me enjoy it for a little before you try and go all Sherlock Holmes on me." She begged him and she can see the wheels turning in his head. Did she reveal too much? Would Derek be mad at her for saying something like that to his brother? Maybe he wanted this a secret like he had with Casey.

Edwin could see the happiness in his step sister's eyes. He wasn't as dim witted as she thought, he knows she's had a crush on Derek since she moved in but never really thought much of it since her and Casey were step siblings. However, since the rumors between Casey and Derek started he can't help but think of about it. He knows he doesn't have any romantic feelings towards either of his step sisters; Casey he doesn't have much of a relationship with but he always viewed Liz as his friend, his partner in crime, and nothing more. He wants nothing more than for her to be happy, even if it was with his older brother. He just hopes she knows what she's doing.

"Just let me know if you ever need me." He says seriously and he sees the bright smile on her face and knows he did the right thing. She gives him a one armed hug before starting to eat her lunch. He shrugs before going back to their usual lunch banter.

XOXOX

As Derek glances over Lizzie's table he's not sure what he's seeing. There his love is innocently talking to Edwin, but it's her actions that make him realize she's putting on a show. That sexy little vixen! He should have know she wouldn't sit by idly while he drove her crazy. His baby was no little lamb, she was a predator just as much as he was!

She's slowly running her thin, delicate fingers up and down her water bottle. The long bottle sweating on the side making her fingers glisten even from across the room. He vaguely wonders how the fuck she found a Voss water bottle so quickly, but he knows his love spends her money on things that better herself or others, instead of cloths or makeup like most girls. In fact the only thing he ever saw he spend on herself was bleaching her hair, which made her look even more beautiful than before.

He looks and sees her send him the naughtiest smirk before completely turning her attention back to her food.

She takes out her wrap and holds it with both hands very gently. The wrap itself was long but thick enough that she had to hold it with both of her tiny hands. The way she was looking at it though made him all too aware she was picturing something else long and thick in front of her.

She opens her perfect mouth up wide making him bite his tongue to hold in this moan as he watches her take almost half of it in her mouth. Her look of pure bliss was going to drive him completely fucking insane. The white dressing covering her lips before her wet tongue licks her lips clean! Oh shit was his girl a temptress! His arousal only got stronger as he watched her go through her wrap, and some strawberries making her gorgeous mouth turn red and juicy. He had to continue looking away before any of his jock friends noticed.

She was playing her power over him very well. His goddess was his true match when it came to the games of seduction. God she was making him want to forget his whole plan and just fuck her into the cafeteria table; showing the whole student body that his girl was not someone to over look. Her flashy sister couldn't hold a fucking candle to her!

"Yo D, what's up with you and you're sister?" One of his not so smart hockey mates interrupted his naughty thoughts. He looks at Jake sharply.

"My seven year old sister is currently in school learning about addition and subtraction. Why?" He asks coldly, knowing what the asshole meant but not giving him the satisfaction of a real answer. Casey and Lizzie were not and will never be his sisters. Period.

"Dude you know what I mean! Casey man! She's been giving you the 'fuck me eyes' all lunch!" He says lifting his eyebrows in a suggestive manner making him want to slap him. He sees Sam and Ralph looking at him to see if he's okay but he pays them no mind. He lifts up from his seat before he's inches away from Jake's face.

"I don't give a flying fuck if she was naked rolling around around in peanut butter two feet away! I am not, and will not ever be interested in Casey! So leave me alone about her!" He says harshly not giving him any illusion that he was anything but serious. He backs away from him and can see the idiot got the message before storming out of the cafeteria. He can faintly hear people whispering about them getting into a fight

"Maybe she isn't enough for him! You can see the passion dying down between them!"

"Maybe he gave her something! Who knows how many girls he's fucked!"

"I think they had a fight! Casey looked so upset yesterday."

"Poor Casey, you can see how much she loves him."

He was seriously considering smacking someone if he didn't get his temper under control. He couldn't believe these morons. He didn't need any of them, he only needed HER! His eyes look with his love for just a second, but that's all he needed to make his anger melt away; he just needed to get away from her bitch of a sister and the people who think she was the one for him.

XOXOX

After lunch, just as school was about to end, Liz goes to her locker to stuff her books inside when she noticed an envelope inside. Smiling softly to herself she picks it up and opened it making sure no one was around. Inside was a list of all his favorite things. Corn Flakes (cereal), hockey (obviously), forest green (color), summer (season), A Bronx Tale (Movie), The Who (TV show), and the list went on and on before she reached the bottom and her heart soared...

These are my favorite things, but out of all of them...I will always choose you. -Always

She smiles to herself as she places the note inside her bag and makes her way to the car where everyone, including Casey were waiting for her.

How did she get so lucky?

As Casey got inside the the driver's seat she couldn't help but think about what exactly she witnessed today at lunch. Just what was going on between her littlest sister and the love of her life?

All she knew was that she was going to find out and get this mess taken care of. She will do whatever it takes to make sure she got Derek back...even if it meant destroying Liz.

XOXOX

That night when almost the whole house was asleep, Lizzie quietly makes her way out of her bedroom and into Derek's. She sees him laying on his bed reading How to Kill a Mockingbird, but she knew he heard her come inside.

"Hi." She says softly standing beside the bed. She sees him smile at her before putting his book upside down and motioning her to sit down.

"Hey yourself. What's up?" He asks taking in her in her night cloths. She was wearing a deep purple wife beater, and baggy boxer shorts; she looked absolutely beautiful.

"I just wanted to tell you I don't want to play anymore games." He looks up at her quickly and scans her gorgeous face to make sure he heard her right.

"So you don't want me to continue with what I have planned?" He asks confused and felt like his heart was going to die. He fucked up! How could he have fucked up so badly already!? She already decided he wasn't worth it.

"No! God no!" She says somewhat loudly before smiling apologetically. She sits down on the bed and takes his hand in hers. It brought sparks of electricity down both their spines.

"I mean...I'm not going to tease you or rush you into anything. I've wanted this for so long and I'm willing to wait a little longer to have you. Completely." She smiles and all he wanted to do was take her in his arms and kiss her. He leans in closer so that his lips are so close to hers.

"You have no idea how much I wanna kiss you right now sweetie...but I can't. I have too much too prove yet." He whispers his hot breath on her lips. He regrettably moves away and gives her a genuine smile.

She slowly gets up and makes her way to his door before looking back at him.

"You don't have to prove anything to me. I've always known you for the man you show the world and the man you really are; and I've always liked every part of you. Always. Goodnight Derek." She says before walking out of his room leaving him speechless.

TBC well that was day two! Let me know what you think.
