(A/N) Sorry for the late update! My friends and I were planning for the Harry Potter movie for the past two days (it was pretty good!) so I was slightly preoccupied. But I'm back! (:

Derek heard the front door slam.

"I'm home!" came the cry of one certain stepsister.

"Don't bother!" he called back, switching on the TV and plopping into his favorite armchair. "The parental units are out with the young'uns."

Casey walked into the dining room and threw her book bag onto the table. "Oh, that's good. I was hoping we could talk about the plan."

"Great idea." He flicked his eyes over her outfit. Speaking of great ideas, the outfit was one of my better ones.

"How'd your talk with Sam go?"

"Fine." He followed her with his eyes, as she moved from the dining room into the living room. "I said exactly what I told you I'd say. And he believed every word."

Casey smiled. "Sounds like Sam." Her expression softened.

Derek rolled his eyes. "Don't go soft on me now, sis. I saw you at lunch. How'd the talk with Kendra go?"

Her expression hardened again. "Great. She doesn't suspect a thing."

"Good."

The stepsiblings smirked at each other in satisfaction.

Casey broke the silence. "Now move," she said, walking toward him. "I want to sit down."

Derek swung his legs onto the coffee table. "I don't think so. I got here first."

"Move, Derek. Ladies first."

"In that case, you don't belong here. Plus, it's gentlemen first."

"Well, seeing how you're neither gentle nor manly, you don't have a monopoly over this armchair either. Now move!" She smirked and leapt onto the chair.

A sharp pain shot up Derek's thighs. "Ow!" he yelled, trying to push her off. "How much do you weigh, two hundred pounds?" His feet were starting to go numb.

But Casey held her ground, digging herself into her stepbrother's lap. "No way!" she smirked. She shifted in her seat, causing Derek to feel something slightly pleasant in his nether region.

"Wait, stop moving, Casey. Seriously."

"Not until you get off." She laughed again.

Derek swallowed. His head began to swim. The sound of the TV sounded distant now. "Well, you're getting me off," he responded, in all seriousness.

Casey turned around, confused. Then, as she caught on, she seemed to shrink into Derek's arms, which were already positioned to catch her.

"Mm," she sighed weakly, leaning her head back into the crook of his neck.

Derek's hands instinctively moved to Casey's neck and began massaging it. Her skin felt smooth under his hockey-worn hands. If there's any justice in the world, Derek thought, Mom and Dad will not walk in right now.

Casey began to move slowly up and down, subconsciously. "That feels so good," she murmured, sounding half-asleep. Derek shut his eyes and swallowed thickly – his throat felt like it was closing up. His thighs were numb in a completely different manner now.

"Did you – find Daphne yet?" Casey murmured.

"No… "

"Then when are we going to get our revenge on Sam? And Kendra?"

Daphne the goody-two-shoes wasn't what Derek wanted to think about right then. All he wanted to enjoy was Casey. Didn't she ever just enjoy herself without thinking? God. "I'm working on it, okay?" he grumbled, eyes closed.

Suddenly, Casey stopped moving, and Derek groaned inwardly. What now?

She lifted her chin to look Derek in the eye. "Okay," she replied. "So until then…" She gently slid out of his lap and strode over to the couch to pick up her book bag.

Derek felt like crying out in protest. He glared at her as she walked slowly up the stairs, knowing full well how much she was tormenting him.

Damn! he thought, as he threw the remote across the room in frustration. I really need to hurry up and find this Daphne girl. Or else, at this rate, I'll never be able to win this bet and the stepsister that comes with it.

Derek spotted the infamous Daphne right after third period math class. He caught her stepping out of the class next to his, wearing a plaid skirt and a white cardigan, looking every inch the model of chastity that she proclaimed she was.

From the safety of his class, Derek watched Daphne opened her locker and sift through it. He flipped his collar up and rearranged his face into a charming smirk before sidling up to her.

"Hey, I'm Derek."

Daphne slammed the locker shut and gave him a suspicious look. "Hi, I'm Daphne."

"I know. I read your manifesto."

She smiled. Derek noted that she was actually pretty – with big green saucer-shaped eyes and long white-blond hair. Not on par with Casey, but still pretty. "Oh?" Her pink lips curled sweetly.

"Yeah, I thought it was terrible."

Daphne's smile drooped. "Oh, that's weird. Most people praise me for it." She hugged her books to her chest and began walking to fourth period.

Derek wasn't going to let her go that easily. He jogged after her. "Most people are lying. Who are you to criticize something you've never experienced?"

She shrugged. "I wasn't criticizing it. I just think that people shouldn't rush into a relationship until they know they're in love."

Derek furrowed his eyebrows. "Are you a lesbian?"

She looked taken aback. "No…"

"Yeah, I didn't mean to offend you. I just picked up on that lesbian vibe."

"I can assure you, I'm not." She paused with her hand on the classroom door, and turned to her walking partner. "Well. It was nice meeting you."

Smirking, Derek watched Daphne Harding walk into her class and shut the door behind her. "Likewise," he replied belatedly.

For the next few days, Derek highly upped his game in his quest for Daphne, incited by the thought of Casey in his arms again. He even went to the office to request Daphne's class schedule (not to see the principal for once) and studied her behavior patterns from afar (studying anything was a major feat for him). Better watch yourself, Derek scolded himself. Next thing you know, you'll be grubbing for grades, like Casey does. He frowned and continued his current task of observing Daphne, who was talking to a friend in the hallway.

"Hey," a voice suddenly sounded behind him.

Derek whirled around in surprise and found himself face-to-face with his stepsister.

"Shh!" He chided, pushing her behind him as he peeked around the wall again.

"What are you doing?" Casey whispered, tiptoeing to get a better look at what Derek was so fervently investigating. Her eyes fixed on the blond girl in his line of view and her lips curled in a knowing smirk. "Oh, so is that her?"

"Mhm."

"She's pretty. I guess."

Derek mumbled another inattentive reply, distracted by the fact that Daphne was now about finished talking to her friend. He was waiting for the opportune moment to strike.

The curly-haired friend bid Daphne goodbye and walked off, passing dangerously close to Derek and Casey's hiding spot.

Recognizing the opportune moment he had been waiting for, Derek burst into the hallway. He reached Daphne as she was tying on her white trench coat and collecting her books. Her eyes widened at the sight of him. "Oh, hello!" she said, slightly taken aback. "This is a pleasant surprise."

Derek smirked. Indeed.

"You're…Darren, right?"

The smirk immediately wiped off his face. "No, um, it's Derek. Actually."

An unsuccessfully stifled laugh came from the direction of his stepsister's hiding spot. Derek turned to an empty hallway and sneered, hoping Casey would catch it.

"Are you okay?" Daphne asked, concern sounding genuine.

Derek felt an unnamed emotion spark in the pit of his stomach as he took in Daphne's bright green eyes. His train of thought ran off-track for several moments, but he quickly recovered it.

"Yeah, I'm fine," he replied, rearranging his face into that characteristic smirk. "Would you mind taking a walk with me? I want to discuss your manifesto."

Daphne looked hesitant. "Actually, my bus…"

"I'll be more than happy to drive you home. I have a car." Though, hopefully, I get to keep it.

"Well…"

Please, please, please.

"…I guess it'll be okay."

Score.
