The next morning was Saturday morning, Derek's favorite part of the entire week. It was the one day that he could sleep in with no interruptions. He looked forward to it all week long.
Casey knew this, so at 9AM, which was like 5AM in DSMT--Derek's Saturday Morning Time, she snuck into his bedroom and evilly jumped on his bed, waking him up.
He glared at her through blurry eyes. "God, Case, come on… it's so early, I—"
Casey cut him off by pressing her lips against his, taking advantage of his opened mouth and sliding her tongue against his. He gave in instantly, knowing that he would never reject her kisses, even if it was 4AM on a Saturday.
He moaned, letting his eyes fall shut as Casey deepened the kiss, shifting her body to now lie on top of him. He was definitely fully awake now.
"Mmm… Case…" Derek managed to groan in pleasure as her lips now moved along his jaw line. He grabbed her hips and pressed her tightly against him, letting her feel just how much he was enjoying this.
She smiled, pulling up his shirt and raking her nails down his bare chest until he let out a hissing sound. She wiggled around on top of him, slowly torturing him as she peppered open-mouthed kisses across his chest.
"Casey, I want you so bad…" Derek moaned as her kisses now moved down his torso. He ran his fingers through her soft hair and then moved down to the hem of the short top she was wearing. She let him pull it up and over her head and he licked his lips at the sight.
She didn't say anything, but Derek could see the lust and desire in her deep blue eyes. Quickly rolling them over so she was now on the bottom, he began to ravage her body.
They didn't hear the knock on the door. Or the door opening.
But they did hear the shriek.
"DEREK! CASEY!"
Derek and Casey quickly snapped their heads over to the doorway, where Emily just happen to be standing. Her eyes were wide and filled with shocked tears, and her face was quickly turning red with anger.
Casey's jaw dropped at having being caught. She scrambled to hide her half-nakedness and Derek could only stare at his girlfriend guiltily.
"Emily!" Casey had yelped. "It's, uh, it's not what you think!" she exclaimed lamely.
Emily just glared from one teen to the other. Her boyfriend and her best-friend. Tears of rage splashed down her cheeks. "How COULD you!" was all she said in an eerily calm but angry tone. She ran off before either Casey or Derek had a chance to say anything.
Not that there was anything to say.
Derek and Casey just remained where they were on the bed, both of them guiltily silent.
"Shit," Derek finally swore, raking his hand through his mussed hair. This was not good. He looked over at Casey, who had this terrified look on her face. Her eyes swam with tears.
"She's going to tell Sam," she said softly, not meeting Derek's eyes. "And he's going to hate us. The two of them are going to hate us."
"It looks like Emily already does," Derek said with a heavy sigh.
Casey finally looked over at Derek, her eyes distant and cold. "We should have never started this," she said stonily and yanked her shirt back on before hurrying out of the room.
Derek sat on his bed in shock. What did Casey mean by that? Was it this morning's make-out session that she regretted? Or was it… everything that she regretted?
Had he just lost his best-friend, his girlfriend, and his secret love all in about two minutes time?
Casey sobbed in the shower so nobody could hear her. The water drowned out the sounds that escaped her lips. Her best-friend—who was really her ONLY friend—now hated her. Her boyfriend would surely be dumping her. And all for what? A stupid affair with her stepbrother!
WHAT had she been THINKING when she started this affair with Derek in the first place? It could never go anywhere. They were step-siblings. They both had significant others. All it was was hormones and lust. That's all. And now she had no best-friend and no boyfriend because of it.
Sure, Derek was hot. And he had amazing lips and a great body. And he could be sweet when he when he wanted to be. But he was her stepbrother. Hello, incest! Her mother and his father were MARRIED. She considered his brother and sister to be her brother and sister.
So it was like she was making out with her brother!
And it was more than making out. In the past, they had gone past first base, rounded second base and even third. In fact, the way they were going, they would have probably been heading home within the next few minutes—that is if her best-friend and his girlfriend hadn't walked in on them.
Stupid. Stupid, stupid, stupid Casey.
On top of that, she was beginning to have actual feelings for her stepbrother. Yes, she had been trying to keep it purely physical and allow herself only to feel lust for him. But that could only go on for so long before things started to change.
She had begun looking forward to seeing Derek more than her own boyfriend. She had let Derek go further with her than her own boyfriend. And she had started to think about having sex… and not with her boyfriend, either.
Whenever she had racy dreams, they were about Derek. Whenever she pictured herself happily married with children, the kids all looked like little Dereks.
It was wrong. She had a boyfriend—Sam—who loved her and treated her like a princess—most of the time, anyway. And she wasn't supposed to be feeling these type of feelings about her stepbrother. It was SO wrong.
And yet, whenever she was with Derek… it felt so right.
Maybe having Emily catch them was a sign. A sign that she was getting in too deep. A sign that she had to end things, and end them now before she got in over her head.
So she called it off with Derek and ran into the shower to cry her eyes out. For now she had to ignore him and spend as little time as possible with him.
And get over him. Before she got her heart broken in the end.
Derek didn't see Casey for the rest of the morning. She didn't come down for lunch, either. It wasn't until dinner that he actually saw her. She sat across from him as she usually did.
She stared down at her dinner sullenly the whole time.
He had tried to catch her eyes several times, to no avail. He even tapped her foot under the table to try to get a response out of her. Nothing. She didn't even look at him.
After dinner, Derek heard Casey on the phone with Sam. He tried to eavesdrop, but all he heard were muffled cries and shouting. It most likely wasn't good. Derek received an instant message from Sam that was very…colorful. He was impressed at some of the words that Sam knew… he had never heard them come out of Sam's mouth before.
It was clear that they were definitely not best-friends anymore. Or friends. In fact, Sam basically said that he never wanted to see Derek again—in harsher words, of course.
And it was also clear that he and Emily were over.
But Derek wasn't that upset about Emily. He had never liked her that much anyway. And Sam… he and Sam had been great friends for years, that is true, but still, Derek wasn't as upset over at his was about something else…or someone else, in particular…
Casey. He had fallen in love with her. He had realized that a long time ago. It killed him to see her with Sam. But knowing that she was his in secret—that was the only thing that kept him from going crazy on Sam.
He couldn't remember how their "secret affair" had started. Or when. It started with the fighting… then it went to bantering… then flirting… subtle touching… kissing… making-out… and other things. They had almost had sex a few times. And he had a hunch that it had been heading that way this morning. And then Emily showed up.
He never thought that she would come over unannounced, early in the morning. Had she even knocked? He couldn't remember… all of his senses had been taken over by Casey.
And now Casey hated him.
Derek knew that he should leave her alone, but that night he knocked on her door anyway.
"Who is it?" Casey asked, her voice strange.
"It's me," he said quietly, praying that she would let him in.
"Go away, Derek," she said in a cold voice.
"Case, I just—"
"Go away!" she shouted, and he heard something being flung against the door. He backed away from the door at that.
"Fine," he spun on his heel and went back to his room, slamming the door shut.
Yeah, they were definitely over.
