Derek pushed her against the car, softly nibbling on her neck "So.. Innocent.." He grinned a wolf like grin.

Cassie let out a small gasp, closing her eyes as she felt his hands trail up the front of her shirt "Do you want this?" Derek asked, grabbing her hand, slowly putting it on his boner

"Yes! I want it so badly.." She whimpered, jumping up and wrapping her legs around Derek's waist, slowly grinding against Derek

Derek growled against her neck, slowly putting his hand up the front of her stomach "Good.." He mumbled, grabbing onto her bra covered breasts

-Dream ended-

She shot up in her seat, breathing heavily and her cheeks were a bright red

"You okay?" Isaac asked, looking back at her in the car

"Y-Yeah.." She stuttered, rubbing her eyes a little. She couldn't believe that she just dreamt of the man she would be living with for a while. She shook her head, putting her head against the window and pulled out her headphones, turning the sound all the way up and turned on Sleeping with Sirens.

"Derek.. Do you think she's okay? Her heartbeat is going crazy.." Isaac whispered, looking over at Derek

"She's fine.." Derek furrowed his brows, knowing that Casandra was turned on because of the smell of her arousal.

Isaac nods, leaning back into the seat "We can't tell her anything.. I don't want her to get hurt or involved with any of our wolfie problems.." He looked over at Derek and then turned and concentrated on Cassie's heartbeat.

"She's okay.." Derek chuckled a little, looking in the review mirror to see Stiles messed up jeep following them

"If Scott's coming for training.. You're gonna have to go to your house.." Isaac mumbled

"I know.. Do you have one of their numbers? So you can call them?"

"Yeah.." Isaac pulled his phone out, putting in Scott's number, waiting for him to pick up the phone

"Isaac?" Scott's voice said through the phone

"Go to Derek's old house. My sister is with us and she doesn't know about our.. Problems.." He said through the phone

"You have a sister?" Stiles voice came through the phone, making Isaac roll his eyes

"I'm on speaker phone.. Aren't i?" He asked, a teasing tone in his voice

"Yeah.." Scott and Stiles said at the same time

"Like I said.. Go to Derek's old house to train."

Cassie slowly turned in her seat, cracking her neck "Are we almost to the house?" She asked, looking over at Derek.

Isaac and Derek froze, hoping she hadn't heard any of the conversation "About 10 more minutes.." Derek said slowly

"Sweet! Um.. What kinda house is it?" She asked softly, hearing a small talking out of a phone

"IS THAT HER?!"
"WHATS HER NAME?!"
"IS SHE CUTE?"

Those were the things she could hear from the phone and she blushed, fiddling with her thumbs

"Yes that's her. Her name is Cassie. And she's my sister. Don't even try touching her." Isaac growled the last part, Cassie's eyes grew the size of golf balls as she heard Isaac's voice.

Derek looked over at Isaac, his eyes flashing a small red color, meaning 'You're gonna scare her!'

Isaac nods, calming down and hanging up on Scott, listening to the sound of his sister heartbeat until it slowed down, all of her fear gone

-10 minutes later-

((Like I said this is AU.. So where they're at for the house is the loft Derek uses in season 3. But you will still be seeing the Hale family house :3))

"Isaac sleeps on the couch.. I sleep on that bed.." Derek scratched his neck "But.. I guess you can take the bed until we get better sleeping arrangements.. So Isaac you're sleeping on the couch. Cassie you're on the bed and I'm on the floor." He nodded

"No! I'm the guest. I can sleep on the floor until I raise enough money to be able to pay for my own bed.." Cassie set her stuff down on the desk by the big window "How'd you find this place?" She asked, turning the two boys

Derek shrugged "Used my computer and found it.." He rolled his eyes, grabbing Casandra's stuff and putting on the bed, a satisfied smile on his lips

Casandra rolled her eyes right back at him, looking up at the stairs "What's up there?" She asked, walking towards the steps

Derek ran and pulled her back, shaking his head "Don't go up there. Got it?" He asked, an angry/scared tone to his voice

Isaac walked over to them, slowly pulling Derek's hand off of Cassie's wrist "Don't you have to go to Scott and Stiles?" He asked

Derek nods, grabbing his leather jacket and his keys "I'll be back later.. I'll bring pizza home.." Derek walked to the door and left, but before he left he glanced over his shoulder, smiling at Cassie before leaving

Please review and um.. Follow the story and me! Thanks!
