A/NThis is my first fic. I really hope you enjoy it. My sister is the one who actually encouraged me to make this, because I was making videos on you tube and she said my plots were cool…So I obviously had the creativity to make a story. If you ever want to check out my vids, which are all LWD and most are Dasey, my name is the same on there as it is on here. And if you are wondering, my sister's name is Dye-My-Hands-Violet. She had this whole joke about me being Dye-My-Hands-Yellow because we are twins. This is going to be third person limited. Meaning I can show you the perspective of more than one character, but not all the characters. I'm going to definitely delve into Casey and Derek's mind, some Lizzie, MAYBE Edwin, and if any, rarely George and Nora. Maybe even a few friends. But I doubt it. Either way... I hope you like this!

DisclaimerI don't own Life with Derek for the pure fact that I don't have a studio, a label, a highly developed creative arts skill, or a zest for the fruits of all things televised. But I have taken it under my wing to throw the characters that aren't owned by me into a plot that I have formed, for the enjoyment of other people who share my hopes and dreams. Enjoy!

Casey walked downstairs after an hours worth of working out to get a glass of water. Lizzie was in the kitchen helping mom cook dinner. She smiled as she walked past them. They were in their own conversation so she left the kitchen to themselves after she got what she wanted.

In the living room Derek was sitting on the couch hogging the TV, but at the moment she didn't desire it. Edwin was talking to Derek, even though it was obvious to Casey and Edwin that he wasn't listening, but Edwin's spirits weren't crushed, it was the way it was all the time. Casey sat at the far end of the couch, and Derek looked up from the TV, noticing her sudden presence rather than the strained presence of Edwin trying to get his attention.

The sweat on her skin began to dry, and left her glowing. Derek's mouth slightly opened, but he knew he couldn't have her, and his mouth closed. She turned to him, thinking that he was an imbecile; the TV was in the other direction.

"What?" Her eyebrows rose.

"Nothing." He responded, but he didn't look away.

"Do you have a problem?"

"Yeah, I do. It's you." Casey made a face at him, and walked up the stairs, slightly stomping her feet the whole way. He smirked. She made it so easy, or hard, one of those. Either way there was no happy medium between them.

Derek started flipping through the channel, but when nothing of interest showed up he tossed the remote to Edwin and walked up the stairs. Casey was in her room, exercising from the sounds of it. He walked into his room and shut the door.

Casey wouldn't retreat from his mind so he blasted his music, hoping it would drown out his thoughts.

She was exercising, trying to get Derek off of her mind. He was such a jerk. Her mind screamed to be somewhere else; a whole floor between them wasn't enough. (Before anyone gets confused on that, she doesn't know he's now upstairs!) If he didn't act like that all the time, it wouldn't be such a problem. But every little thing he does is another molecule of a drop to a pot full of boiling water, just waiting to boil over. Casey punched the air.

Derek got up to check his mail. He got one from Kendra.

Hey Der!

I know we haven't talked all summer, great friends we are huh? My brother, his girlfriend and I are all going to the movies. They'll probably be having a make-out session and I'm looking for someone who will make me feel more comfortable! Reply back ASAP. We are going Friday!

Love,

Kendra

He put his hands behind his head and smiled. After a few moments of random thought he reached out and clicked 'reply'.

Kendra,

Yeah, sure. Sounds great! I'll make sure my dad and Nora don't have any plans.

Derek.

Derek clicked send and turned down his music, no longer thinking of Casey.

An hour or so passed and Casey again came out of her room, sweating, at the same moment Derek came out of his room. Unbeknownst to either of them, they both left their room for a shower. Derek stopped to look at Casey. He liked it when she was sweaty, and he liked it when she got dirty. She was always this fresh, clean, and orderly being, but he often imagined what could happen when that table turned. His mind always raced with thoughts of her drenched in rainwater, fighting with another girl, her ponytail falling out, and bra showing through her light colored clothing.

It didn't bother him that it was her step-sister. He figured if he didn't act on it, he'd be alright. Looking but not touching, was hard, but not harmful. And she'll never have any idea.

Casey glared at him, wondering what his problem was. What is he up to now? I hate it when he looks at me like that! I like it…for the strangest reason, but I know that when he looks at me like that…he did something. Or is going to do something.

"What did you do?" Casey snapped the silence. He smirked.

"Nothing." He gave a small laugh and started toward the bathroom. Casey saw his direction and attempted to run in there first. Derek rushed into it and Casey pushed him in further so she could get in there. He stumbled back, not expecting a new tactic, and Casey continued the assault by twirling and flinging him out of the bedroom.

Derek landed with a hard thump on the floor, and Casey laughed out loud as she slammed the door.

Lizzie peered out of her doorway, afraid to find out what was going on. She was glad to see that whatever happened was over. As soon as she thought that Derek got up with a look of anger, anger that she didn't see often in him, and he banged on the door. When nothing but a hysterical laughter answered it, he opened it and shut the door.

Lizzie turned and went to her bed, afraid to hear anything or see anything, and turned on her pop music.

Derek froze at the sight of a half-naked Casey. Before his eyes wandered he turned away to face the door. He half expected Casey to scream at the top of her lungs once she caught her breath, but after a few moments of silence Derek felt a jab of Casey's fist dig into his back. He fell forward slightly then turned to face her. She was still naked from the hips up, but at that point he didn't care. She's NEVER hit me. This crosses a line.

"What did you do THAT for?" Casey crossed her arms over her breasts, as though she were fully clothed, and gave him a 'duh you imbecile' expression. His eyes faltered slightly, knowing it was a dumb question, but held his stance.

"I need the shower, I'm all dirty and I need to be clean! You're always going to be filth no matter what you do." With that sentence he realized her ponytail was out. He could see a line through her hair where her ponytail gripped her strands of hair. It stuck out in odd places, giving her a look of sophistication, yet messy and seductive. Her sweatpants hugged her hips, and her belly was toned perfectly.

"You're always using the shower. We had that whole thing about shared space, remember? You are the one who wanted to share and look here you little hypocrite!"

"I am sharing it. You can have it after me." Her lips pursed. Derek decided that he no longer needed to comment. One hand gripped her shoulder firmly and the other opened the door, he pushed her out and slammed the door.

Derek, however, remembered to lock it.

Casey fell on her butt just as Derek did. She heard the shower turn on and a look of horror went across her face. Casey got up and tried to open the door, but when it wouldn't open she pulled violently on it over and over.

Edwin came up the stairs and looked at her. Quickly turning away he cried out for help. Lizzie ran out and looked at Edwin. His fright-stricken face scared her, and he pointed a finger back at Casey.

"Casey! Where's your shirt!!" Lizzie cried out. Casey looked down, and started crying as she ran to her room and slammed the door.

Edwin and Lizzie just looked at each other, reveling in what they had just seen. He gave her a look that she had become familiar with, and they both decided without speaking words, to investigate Derek's intentions of throwing Casey out, naked.
