Nothing mattered except getting everything perfect. The second the car was stopped in the driveway Casey ran to the door. A cold wind followed her and as Derek opened the door behind her a blast of snow danced around her.

"Stupid snow," Derek muttered. Casey looked up and squinted at him, despite the sun setting earlier it was still brighter outside than it was inside.

"You love snow," she said, "I love snow. You're Canadian. Get used to the snow."

"You love snow?" Derek's face brightened. "I had you pegged for a sandy beaches and bikinis type of girl."

Casey, still confused on how fast their argument had ended, smiled weakly. "All the seasons have certain, um, perks to them. Bikinis are the perk of summer." She turned to go upstairs but as she hit the steps she was certain she heard Derek, mutter, "I can't wait for summer."

She blushed bright red, remembering the shocked look on his face when he'd seen her in her underwear. Speaking of which, she rushed over to her underwear drawer and muffled a scream when she saw her favorite pair, her special, lucky, kind of sexy pair of underwear was gone.

"Der-ek!" She rushed into his room, her face burning. "Where is my underwear?"

He looked at her like she was crazy. "Your…underwear?"

"Yes, my lucky underwear," she snapped, "they were in my drawer and now they're…tucked under your mattress." There, at the foot of his bed was a piece of turquoise lace. She rushed over and pulled them out. "Why do you have my underwear?" she demanded.

It was his turn to blush. "I know they're your favorite," he replied with a shrug as he reached under his mattress and pulled out the matching bra. Casey gasped. "I figured they had to mean something to you. What I didn't realize was that they were your 'get lucky' underwear."

"They are not!" Casey snapped grabbing for her bra. "I just…liked the color."

"Right," Derek replied, holding the bra out of Casey's reach. "It has nothing to do with the fact that they're sexy enough to turn almost any guy on."

"Well I never thought you'd be seeing them," Casey replied angrily. How was he so calm just holding her bra like it was a sock? "They're my lucky underwear. I wear them when I need a little boost of confidence."

"Like you need more confidence," Derek muttered as he stared at the bra. Then suddenly he seemed so realize something and a smirk spread across his face. "You were going to wear them tonight weren't you?"

Casey opened and closed her mouth several times, trying to think of something smart to say to get her out of this situation but she found herself speechless. She couldn't believe that she'd been stupid enough to let him onto that little fact. He was never going to let it go.

"You were going to wear your sexy underwear for me." Derek was practically singing it now. He looked overjoyed. Casey wasn't about to tell him she'd planned to wear them after dinner tonight and wear them tomorrow for a little boost with Vincent.

"No," she snapped. "I was just…looking for them. A bunch of my stuff has gone missing."

Derek went suddenly somber. "Stuff like what?"

"Like my books," she replied. "The ones you always make fun of me for reading. I can't find a bunch of them."

"I don't know where they are." Derek shoved the bra into her hands and then pushed her out of his room. Casey was confused. What was with the sudden mood swing? Did he know something about her books? Usually he'd tell her if he was up to something.

"Hey Casey," Edwin said as he passed her coming out from Lizzie's room. A satisfied smile on his face while Lizzie glowered at him from her door.

"Hey Ed…" Casey looked back and forth between her sister and step-brother. "What's going on? How's it going with that girl?"

Edwin went bright red and glanced back at Lizzie nervously. "It's going good," he muttered. "I think."

Lizzie was beaming. "Edwin has a crush?" she asked slyly. "On who?"

"No one," he snapped and bolted. Casey and Lizzie exchanged a confused glance.

"Why are you carrying your underwear?" Lizzie asked finally.

"No reason," Casey replied quickly and walked into her room quickly, leaving Lizzie alone and even more confused.

Once alone with her thoughts Casey realized a breath see hadn't been aware she'd been holding. Her nerves felt like they were on fire, her stomach was clenching and unclenching like she'd just run a marathon. She stared at the flimsy pieces of lingerie in her hands, was this really all it took?

These little pieces of cloth…

She slowly slipped off her school clothes, and then slowly out of her underwear. She pulled on the underwear and then stood in front of the mirror. Amble breast support made her usually smallish breasts seem larger and the boy short lace underwear looked, well nice. She giggled like a school girl as the thought of Derek's face if he saw her in these passed briefly through her mind.

Then another thought ran through her mind. Find another boy.

That was her new mission. Once her stupid story was in and this stupid bet was over she planned to never think about Derek. She pulled her overly large shirt over her underwear and flopped down on the bed. Rose was so sure of herself. How was Casey supposed to be Rose?

At exactly five-thirty a sharp rap resounded at Casey's door. There stood, Derek in a dark blue dress shirt and jeans. Next to him Casey felt invisible. She's curled her hair just like Rose and she was wearing a slightly 'prudish', knee length black skirt and a baby blue scoop neck cashmere sweater.

"How do you know Oliver would wear something like that?" she asked. Derek shrugged.

"I winged it." He glanced around the hallway before shoving her jacket in her hands. "The less they see of us, the fewer questions."

"Do they even know we're going out?"

"It's a date Casey," Derek replied quickly. "We're not dating." Casey rolled her eyes, though her heart skipped a beat at the idea.

"I meant going out tonight," she replied. Then by some uncertain force stood on her tip toes and brushed a few strands of hair away from his eyes. His hand shot up and caught her wrist.

The sudden action made Casey fall forward a couple inches and she found herself standing so close to Derek she could feel his body heat sinking in her body and she could smell his aftershave. His face was just inches from hers, his lips so close she could almost taste them. Her eyes fluttered up to meet his in what should have been an awkward stare down but instead made Casey want him more.

His hand gently slid up from her wrist to rest on top of hers as he brought it down against his cheek. His breathing was getting slightly ragged and louder. It took Casey a few moments to realize she was reacting the same way. She could feel his soft skin under her hand and felt his other hand just barely brushing her skirt.

His lips were suddenly right in front of hers, his eyes stared into hers asking her to make the final decision. This wasn't like this afternoon when everything was hurried and embarrassing. Casey wanted this. His hand was brushing her thigh, ever so gently and the other slid up and down her arm, his thumb dragging ever so slowly up and down the inside of her arm.

Dizzily Casey realized she was surprised at how sensitive the skin was there. Trust Derek to know that. Her stomach was clenching and unclenching dangerously. There were so many consequences to either choice. It was like knocking on a stranger's door; she could knock and face the danger or walk away.

Not allowing herself to ponder her choices any longer she leaned up and pressed her lips to his, briefly in a peck. The second afterwards Casey knew that Derek wasn't going to allow her to walk away. He wrapped one arm firmly around her waist as his lips pressed into hers. Desperately he kissed her like a drowning man gasping for air. He danced them into her room, closing the door firmly behind them.

Casey couldn't think as he gently pressed her onto her bed. His hands were everywhere. His lips burned against hers with a fire she'd never felt before. As his hand teased her at the edge of her sweater she could hear voices.

"Derek," she gasped. "Derek, someone's…"

She looked over at the door to see the handle slowly being turned.
