Author's Note: Quick note from me this time; just a thanks for the reviews! You all are so great!
Derek woke up the next morning, glad to find his bed empty. There was a note there, though, that said, "Derek—Thanks for the fun—XOXO, Ashley."
He had slept with her. And, in the throes of passion—he had moaned out his stepsister's name. Thankfully, Ashley had been too drunk to notice. She passed out as soon as they were finished.
He hadn't meant to say it. But it had just come out. Sure, he had been thinking about Casey in that hot dress while he was screwing Ashley. Wishing that it was his stepsister that he was thrusting in and out of. But he had never imagined that he would actually moan out Casey's name.
Derek grumbled to himself as he got out of bed. It was early for him to be up on a Saturday, but he was certain that he wouldn't be able to sleep anymore. He groggily grabbed a few things and jumped into the shower to erase everything from the previous night.
When he was exiting the bathroom, his hair wet from the shower and a towel haphazardly draped around his waist, he was taken off guard by his stepsister standing outside the door. She had her own shower supplies in her hand and was impatiently tapping one bare foot against the hardwood floor as she waited for her turn for the bathroom. Derek blinked several times, as if not actually computing that she was standing there just centimetres away.
"Hey," he said coolly, trying to collect himself quickly.
"Hey," Casey shifted on her feet awkwardly. "You know, I heard you last night," she said after a few seconds. She gave him a Look and then brushed past him, shutting the bathroom door behind her.
Derek stood there in shock.
"Shit," he murmured as he made his way back to his bedroom. She had heard him moan her name out? What was he going to say to that? How was he going to get out of that one?
He quickly dressed and waited for the sound of the bathroom door opening again. As soon as he did, he bolted out the door. Casey stood in the hall with one towel wrapped around her dripping wet body, and the other wrapped around her hair turban-style. Derek gulped as his eyes trailed down her body and all words of what he had been planning to say flew out of his brain.
Casey looked over at her stepbrother. He was giving her this strange look she had never seen before. Clutching her towel more tightly against her, she asked slowly, "What?"
Derek shook his head, trying to clear his thoughts again. "Uh…"
"Okay…" Casey looked at him oddly and continued her way to her bedroom. Once in, she turned to shut the door behind her, only to see Derek's hand extend out to stop her from shutting it.
"What did you hear?" he demanded, stepping into the room.
Casey backed up slowly. "What?"
"What'd you hear last night?" Derek's eyes burned right into hers.
"You and Ashley having sex," Casey raised an eyebrow accusingly. "You were loud."
Derek let out a breath. "Yeah, I'll try to keep her more quiet next time," he retorted quickly, just to piss her off.
"You're disgusting," Casey raised her nose indignantly.
Derek's smirk dissolved and he asked seriously, "Is that all you heard?"
Casey felt her heart speed up. Was he talking about…? Had that been real? "Uh… what do you mean?" she responded as coolly as possible.
Derek studied her for a moment, before finally saying, "Forget it." Letting his eyes trail appreciatively down her body one last time, he turned and left the bedroom.
Casey speechlessly watched him leave.
Derek spent the rest of the day just lounging around the house. He watched some TV, played a few games with Marti, beat Edwin twice at a video game, and surfed around on the Internet. He said "hi" to Sam when he came around five to pick up Casey, and watched Casey with secret yearning when she left with his best-friend.
Nora and his dad tried to make small talk at the dinner table, but Derek said that he just wasn't feeling very well and excused himself to his bedroom.
That night when Casey got home, Derek turned on his music so he wouldn't have to hear her humming some sappy love tune because she had such a great time with good ol' Sammy.
He never expected Casey to walk into his room.
She looked like she was on a mission. She walked right up to Derek and demanded, "Why did you say my name last night with Ashley?"
Derek's jaw dropped. He couldn't believe what she was asking him. The look in her eyes was both defiant and daring.
It exhilarated Derek.
He pushed her down onto his bed, causing her to yelp in surprise. "Derek!"
He pinned her wrists down and locked her under him so she couldn't move. Her eyes were wide and a little bit frightened.
"I said your name last night," he hissed closely to her face, "because I was thinking about you. While I was screwing the blonde whats-her-face, I was picturing that it was you."
"What?" Casey gasped in utter shock. She never in a million years would have guessed that.
"I want you so bad, Casey," Derek admitted with a slight groan as she shifted a bit under him, brushing up against his growing arousal. "I want you so goddamn bad…" his voice became a bit lower and he breathed in her amazingly sweet scent.
Casey could only stare at her stepbrother as he confessed this to her. All of this time she had thought that he hated her… that their passionate fighting was all about dominance and the rule of the house. Territory.
She had never seen the underlying yearning from her brother underneath it all.
"Derek…" she whispered. She was scared at the look of desperate want in his eyes and how he had her pinned underneath him.
"Sam doesn't deserve you," he told her in a low voice as he released one of her hands so he could move his down to her stomach. Slowly he moved it under her shirt and upward to cup one bra-covered breast. She gasped out loud at the feeling.
"And you…" Casey tried to remain strong under his gaze and touch. "You deserve me?" she asked almost accusingly, her eyes steady on his.
Derek leaned down closer to her face. "No," he whispered, slowly sliding his tongue out to lick her lips. "But I want you anyway…"
