Breakdown

Casey was yelling at Derek in his room. Her face was furious as she continued ranting about his latest stunt. He always caused so much damage. She would have refrained by now, but he seemed so amused which frustrated her more."...So this is how you get your kicks. Never mind how I feel..."

Derek thought to himself, if she only knew. She rolled her eyes in disgust. How could she not see his affection for her. Never had he cared about or lusted for another being before. God how long had he kept this inside of him? This feeling burning to be released. Way too long. In his head an image of Casey's pretty smile played. That smile was like a precious gift to the world.

"...Do you even respect me Derek?" she asked finally pausing.

Derek accidentally let the words fall out "I cherish you." Though it seemed Casey couldn't get angrier she did.

"You are such a smart ass!" she cried as she slapped him releasing all her anger. She realized what she had done and wanted to take it back. Derek was completely stunned.

"My God I'm sorry Derek." she said the look in her eyes had told Derek that already. She took a step closer to him placing her hand where she had left a red print on his face. She caressed his cheek and Derek closed his eyes trying to calm the need and want of his stepsister.

Casey removed her hand and he opened his eyes. Before thinking he found his lips meeting hers. Casey opened her mouth to protest but slowly Derek deepened the exploration sliding his tongue in. His hands gripping her waist.

She took a step back but he followed, never leaving her mouth. Casey could have done more but she didnt want to. She let herself go, kissing him back, enjoying the anxiety of her insides as they rallied in unexpected hunger.

There had been times she had to admit Derek was a attractive on the eyes, but the thought of kissing him never entered. He was her stepbrother after all. With that thought she pushed him off her. "Whatever cruel mind games your playing it is so very wrong brother."

"No its not like that Case." he assured her. She opened the door to leave Derek's room but he grabbed her hand to stop her from leaving. She shrieked bloody murder and he released her. She walked to her room and closed her bedroom door.

"Wow what was that scream?" Edwin asked from the hallway to Derek who was standing outside Casey's door.

Casey was lying face down on her pillow. Could I have felt this way subconsciously but never have know, she thought. I cant possibly feel this way. But I never thought of him as a brother she argued with herself. But your parents and the rest of your family do, she retorted. Great she thought I just lost a debate to myself.

Oh well, she thought, just let it go. Easier said than done. Like he feels that way about you. He must have had his fun with all the other pretty, mindless girls in town and was now targeting you.

Someone knocked on her door. "Go away!" she called out. "Its me." Edwin replied. She told him to come in. He did so. "I have a message from Derek." Casey groaned but he continued. Derek listened from the hallway.

Edwin gave the speech. "Derek says he is very sorry. He never meant for you to know what he thought about you. He just couldn't restrain himself any longer...Did he call you the b word?"

Nora called everyone down for dinner and suddenly Edwin didn't care he was running downstairs. Casey dragged herself up and took a step into the hallway as Derek stepped in front of her path. He asked debonairly "So do you forgive me? You do remember your the one who slapped me, but your not sending me midgets to apologize."

Casey refused to answer, they needed to get downstairs. She tried getting around him but being 'Klutzilla' she could not help brushing against his arm and side. Having felt her again, Derek grabbed her forearms and pushed her back against the wall roughly. She bit her lip trying to deny what she felt when he was so close. "Please don't Derek" she begged fear in her eyes that he would kiss her.

Seeing her scared still pinning her forearms to the wall he whispered in her ear softly "I would never hurt you Case." He looked back at her now passive face and let her go and followed her downstairs to the kitchen where everyone was waiting for them.

Casey tried to hear her stepfather's story about work, but her thoughts were too much--too loud. She remembered Derek's hands on her waist and she shivered impulsively. Her eyes found him. He met her gaze and gave her his cocky grin. She looked away feeling ashamed that she was allowing him to get to her so easily.

George finished his story and everyone laughed with the exception of Casey who had missed it. Nora took notice. "Casey dear are you alright?"

"Mmhmm" was the answer. Lizzie blurted out what Edwin had told her "Her and Derek had a fight."

Derek announced before he could be scolded "I did apologize."

Nora said to Casey "Honey he says he apologized. Now would it not be responsible to follow Derek's example?"

Casey felt wrongly accused "I will not." She began speaking quickly until it was almost unintelligible "Derek believes he is God's gift to this family and anything with a skirt. Everyone on this damn earth may fall for him--not me. But no that's not good enough for Derek. He wants it all. He wants me to join that worldwide conga line singing 'Whatever Derek wants, Derek gets'. Sure as long as it pleases him I should let him get the best of me. I'm just another object for him to satisfy himself with. To hell if women feel or bleed!"

Ashamed and exhausted she pushed her plate back, set her elbows on the table, and covered her hands over her forehead. "That was pretty awesome." Marti sang.

Casey stood up leaving the dining room. "Dear what has got you so stressed?" Nora asked concerned not sure what to make of her daughter's outburst.

"I'm fine mom" Casey called out nonchalantly climbing upstairs.

"I think Derek called her the s word." Edwin said.

"Whoa I didn't call her anything. May I be excused and check on her?" Derek asked doing a great job of hiding his emotions.

"Dont you think you caused enough damage?" George asked his son.

"I think Casey should see a psychiatrist." Nora told her husband.

"We'll discuss it after dinner." which meant no more talking of the matter.

She laid on her bed face down. Casey wiped her tears determined she could just as easily toss her feelings. She knew she had to accept Derek's apology. She would forget his mean jest.

I mean why should she dwell on what she couldn't have. Derek is a pompous womanizer. She had Sam. She didnt need Derek. And yet Derek had opened up such deep emotions that Sam hadn't. It doesn't matter she told herself.

There was a knock on her door. Casey really didnt want to talk to her mother, but knew she had to convince her that she was fine. She sat up, fixed her hair, and wiped away her tears. "Come in," Casey called out and smiled.

Derek entered closing the door behind him. He watched her cute smile drop. "Would you leave me alone?" she spit out irritated.

"They want you to see a shrink Case." he said trying to be reasonable.

"I already see Paul."

"Well it appears your unstable mental state could get worse." he insulted.

"I blame you." she attacked. Her eyes were lit up and Derek wanted to his reflection in them. She stood walking to the door.

He said in an effort to make her stay or not kick him out, "You aren't acting very mature about this at all."

"Like you would know anything about maturity."

"We need to talk."

"No we dont because I forgive you. Now let's forget about this whole day ok." She twisted the doorknob, but Derek used his weight to shut it.

He banefully spoke "You always think your so right. That you know so much more than anyone else. Well you were wrong. Your entire tirade downstairs was so far form the truth."

He walked to the other side of the room running his hand through his hair. His voice lightened. "I dont care if after I say what I need to you are completely nauseated by me. I just cant have you thinking that I see you like any other girl I've been with. It was no sick joke that kiss. I have been trying to hide how I feel about you and I finally cracked. I love you Case."

She was in shock. She wanted his voice to repeat it again and again. Seeing Casey's smile, he grinned. "I didn't think that would be your reaction." he said.

"What about this?" she asked surrendering, kissing him fervently. He kissed her back just as urgent.

"Only when I deluded myself." he murmured in between taking breaths. Her lips welcomed his taste, her tongue gently gliding into and caressing the curious insides of his mouth—teasing, and calling him to her. Derek kissed her chin going down to her neck. His eyes dark filled with desire.

Derek felt so good as she savored the way his kisses made her feel. She saw the door as she arched her neck suppressing a moan. Casey had almost forgotten her family outside that door.

"Derek stop" she frantically said. He looked confused.

"We can't do this. You're my stepbrother." Her hand was on her forehead.

"Its not like that with us. Its okay" he replied.

"If its okay then why would our parents freak if they knew. If Emily or Sam knew. Did you forget I'm still with him?"

Like he could forget why he despised his best friend. "You care about him a lot." Derek said bitterly.

"I'd so much rather be with you. Ugh! I shouldn't say that. I shouldn't think that!"

She turned her back to him. He wrapped his arms around her waist. "Dont think about them now. Forget the world. " he said. She turned to face him. "I cant."

"Try." he demanded kissing her lips tenderly. His tongue aggressively entered her mouth.

The door pounded outside.

"Let me in! Let me in!" Marti cried. Derek and Casey pulled apart. Casey opened the door.

"Smerek. What are you doing in here?" Marti talked loudly running to her brother. He lifted her in the air.

"I was waiting for Casey to apologize."

"Did she?" Marti asked.

"I think she covered most of it." There were a few dollar bills on her dresser. He snatched it up shoving it in his pocket saying, "This'll cover the rest."

"That's mine." Casey raged.

"Come and get it, sis" he provoked her. She crossed her arms thinking to herself she would, she would.

"Come look at what I did with the toothpaste." Marti interrupted.

"I'm right behind you Smarti."

Marti sped off to the bathroom before following his little sister, Derek grabbed the back of Casey's hair forcefully and kissed her lips. "I love you too Derek." she said breathlessly. He gave her one last smirk before walking into the hallway.

She smiled like a fool and sighed contently after closing her bedroom door. She heard her stepsister squeal from the bathroom. She heard the echos of Derek's laughter soon after. As Casey sat on her bed taking hold of her pillow, she saw her stepbrother in her mind grinning his eyes cryptic "Sis" he taunted. Her face fell into the pillow as she sobbed.
