I'm used to writing smutty stories, but this is my first Life With Derek story! I'm used to writing for the Private series, and the Degrassi TV show.

Well, I hope you like it! I was going to make it a one-shot, but then I had more ideas that couldn't all fit in a one shot, so I'm hoping this story goes to about 10-25 chapters. Fingers crossed!


"Dad!" Derek yelled George, his father. Was he hearing things?

"You heard me, Derek Austin Venturi." George told Derek sternly. Derek could hear Casey giggle softly at the use of his middle name, standing closely behind him, watching the scene play out in front of her eyes. "I told you to take Casey to Sam's party with you."

"But why?" He groaned, turning around to face Casey. She was in sweats, no make up on, and her hair in a tight pony tail. "She isn't even ready!"

"Casey is used to getting ready fast, Derek. She's a dancer who went throught many recitals, you know." Nora, Casey's mother and Derek's step-mother said, sitting down on the couch next to George. Lizzie, Edwin and Marti were all sitting on the floor in front of the TV, watching a movie, but they were currently destracted with the event in front of them.

"Come on, Derek. It'll be fun!" Casey said with mock enthusiasm, grabbing his bicep. She didn't want to go just as much as he didn't want to take her. It was a Saturday night, and she wanted a jump start on her homework.

"Get the hell off me and go get dressed, Space Case." Derek hissed at her just quiet enough so their parents couldn't hear them. Casey rolled her eyes and ran upstairs to her room to get dressed.

Casey closed her door and leaned against it once she was inside, her stomach filled with tiny little butterflies. She was nervous. She heard Derek come home from these types of parties. He would always bang and crash around from opening the door, all the way up to his room. She always helped him to bed, and she didn't really know why. She closed her eyes, thinking of the last time she helped him.

Casey's eyes snapped open at the sound of the door open with force. She heard clumsy footseps try to make their way upstairs, tripping every once and awhile. She would hear him run into walls, knock over tables, and trip himself with his own two feet.

Casey threw the covers off her body and opened her door to the hallway. She tooked towards the staircase, and sure enough, Derek was sitting against the wall, halfway to his room. His head was thrown back against the wall, his brown eyes were closed, and his legs were put lazily in front of him. He was trashed.

"Come on, Derek." Casey whispered, grabbing one of his hands, trying to pull him up. He just let her pull him up. He leaned on her and put his arm lazily around her shoulders as she tried to make her way to his room, his strong, hockey toned body weighing her down.

"You're a great little sis, Case!" Derek yelled, and Casey quickly put her hand over his mouth, but not before she smelt the alcohol on his breath, causing her to turn her face away from him.

"Sush, Derek! Mom and George can't know you're drunk."

"And high," Derek said with a hiccup and a laugh. Casey just rolled her eyes and walked him into his room, laying him face down on his bed. He fell asleep right after Casey turned off the light and closed the door.

Casey sighed as she pushed herself off her door and walked over to her closet. She wasn't ready for that to become her.

She opened her closet and thought to what Derek was wearing. Dark wash jeans, his usual skater shoes, a black t-shirt with a band Casey didn't recognize, and a black leather jacket. Casey pulled out a bright red, skin tight strapless dress and looked at it hesitantly. It was way out of her comfort zone, especially since she's going to be with Derek.

After less than ten minutes, Casey found herself in the red dress walking downstairs, and Derek looked at her, taking in her outfit. She had on black strappy heels, her skin tight, short and strapless dress that started right above her mid thighs, making her tan legs look like they went on forever. She had on a cropped black jacket that matched her heels. Her long, silky brown hair was in loose curls and her bangs pulled to the side with a diamond clip. Her bright blue eyes were played up with a smokey eye and thick mascara, and had a pale pink lip gloss on.

"Wow, Case. You look... older." Nora said, picking her words carefully.

"I think you look like a beautiful young lady, Casey." George said with an uncertian smile. Casey just blushed.

"Ready to go?" Casey asked Derek with a bit more confidence.

"Uh... yeah. S-sure. Let's go." Derek said, distracted with what his step... what Casey was wearing. After seeing her in this outfit, he could never see her as his sister. Ever.

"Bye mom! Bye George!" Casey called over her shoulder, leading the way out to Prince. Derek couldn't help staring at her backside as her hips moved side to side. When he realized what he was doing, he shook his head and look straight ahead. Derek and Casey both got in the car, Casey already complaining.

"Why does your hockey gear have to be in the passenger seat!" Casey whined, moving it from the seat to the floorboard.

"To bug you, Casey! That's why!" Derek yelled at her, concentrating his eyes on the road.

"No need to get hostile." Casey sniffed, crossing her arms across her chest, turning her head to look out the window. They rode the rest of the way to Sam's house in silence, neither of them wanting to say the first word.

"We're here, get out." Derek said, shutting the car off and slamming the drivers door closed behind him, wincing at the loud noise it made. He started to walk inside, but Casey put her dainty hands on his bicep, stopping him.

"Derek, I don't know anybody!" Casey said with a bit of panic in her voice. If Derek was off probably banging some random girl, what was she supposed to do?

"Make friends," he said, shaking her off as he continued to walk inside. Right before he opened the door, he turned around and saw Oscar, a player on his hockey team, flirting with Casey. Derek thought he felt a pang of jealously, but he shook it off as he opened the door and was instantly greeted with a beer.


Three hours and almost five beers later, Derek was sitting with Sam and some other hockey buddies, talking about girls.

"What 'bout her?" Sam slurred, pointing at a short blonde with big breasts spilling out of her shirt and way too much mascara on. The rest of the team nodded with agreement while Derek scrunched his nose. For everyone else, people got hotter the more drunk they got. For Derek, he got more girl picky.

"Fuck, Derek! Isn't that your step sister?" One of the guys said, pointing a shaky hand at Casey, who was stumbling her way over to Derek and Sam.

"Hot damn, man. You hit that yet?" Sam, who was across from Derek, asked him.

"Naw man, she'd kill me. And she's fucking annoying." Derek said, trying to shake off the idea of Casey riding him hard, even though his pants got a bit tighter.

"Now's you're time!" Sam said loudly, tripping Casey at the right moment, and she fell right onto Derek's lap.

"Ohmygosh, I'm soooooo sorry!" Casey said to Derek, her eyes wide. She stayed in shock mode a little longer before she burst out laughing, making Derek laugh too.

"It's cool Case!" Derek slurred as he wrapped one strong arm around her back, and snaking the other under her legs, moving her so he would be more comfortable. Casey giggled and hiccuped, leaning her head against his chest, trying to stop the room from spinning. Derek looked over at Sam, and Sam just smirked, stood up and started thrusting his hips into the air, silently telling Derek to fuck Casey. The rest of the hockey team burst out laughing.

"Case," Derek said, nudging her head with his shoulder. She just groaned, her hand playing with his t-shirt. "How many drinks did you have?"

"Ummm... I lost count after seven!" She giggled, looking up at him. Derek just groaned. He was very drunk, but not nearly as trashed as Casey. There's no way she'll remember tonight. "I need to get you home."

"No! I wanna stay with you!" Casey said loudly, throwing her arms around his neck and sloppily holding him close. She pressed his body to his in the action, and Derek wish she hadn't, because his pants got a bit tighter. Despite her attempts to fight him, Derek held her tighter in his arms as he stood up, still holding her. He managed to carry her all the way to the car without falling down. Derek threw her in the passenger seat of Prince and walked over to the driver's side, starting the car. He also managed to make the very short drive through the neighborhood home without going off the road.

"Casey, we're home. Get out." He said tiredly, nudging her shoulder. She's been asleep the whole two minute ride home. She fumbled with trying to open the car and stepped out, slamming the door behind her. Derek walked ahead of her so he could unlock the door, but Casey grabbed his shoulder, stopping him in his tracks. Derek turned around, and right when he was fully facing her, Casey slammed her lips down sloppily on his. Derek was taken aback, but kissed her back anyways. He grabbed her upper thighs and picked her up, and Casey wrapped her legs around his hips.

Unstable on his feet with Casey clinging to him, Derek somehow made it to the front door without breaking this kiss. He broke away from her right before opening the door to check the time on his watch: 1:27 A.M.

"Case, listen. You have to be quiet. Everyone's already sleeping." Derek whispered to her, Casey's eyes never leaving his lips. Derek was still totally drunk, but he had a lot more common sense left than Casey, who probably drank more than twice her body weight in a period of five hours.

"As long as I get to sleep with you tonight." Casey said with a wink, running her hands down his chest lightly, her fingertips leaving lines of fire underneath Derek's shirt.

"I'm going to hell for this," Derek whispered before claiming her lips again. He managed to unlock the door, and closed it with his foot behind them. He carried Casey upstairs to his room, throwing her on the bed under her. One hand stayed on her hip, keeping her in place, while the other one flew up to her face, his grip shaking in anticipation of what he knew was going to happen very soon.

Casey wasted no time getting to what she wanted; her hands were already under his shirt, taking the unwanted fabric off of his body. When his shirt was off, Casey stopped kissing him long enough to take in what his body had to offer; ripped chest muscles, tight abs, and firm biceps and triceps, all from years and years of intense hockey practices. Casey ran her hands up and down his back as he captures her lips again, moaning into her mouth. His hands found themselves under Casey's dress, inching themselves higher and higher up her inner thighs, making her squirm under him. With one swift movement, Casey's dress was off her body and on the floor. Derek pushed himself off of Casey a little more, taking in the woman under him. Casey's whole body was tall, tanned and lean, thanks from years of long dance practices. She had on a light purple lace thong, and no bra on.

"Damn, Casey." Derek whispered as he hooked a finger under the lace, pulling down her thong, earning a hiccup/giggle from Casey. Derek sat up on his knees, trying to undo his belt with shaky hands. His big hands were swatted away by small, steady hands, undoing his belt and pulling his pants down, a his boxers came down with them. Casey flipped them over so she was straddling him, skin on skin, naked on naked.

"Please, Derek." Casey begged him, turning him on even more. "Please fuck me."

Derek flipped them back over so Derek was on top. He quickly slid into her, both letting out throaty moans. Derek saw stars as he thrusted harder and harder into Casey, earing louder and louder moans.

After ten minutes of non-stop moans and thrusts, Derek finally felt himself stiffen, knowing he was close.

"Let go, Case." He whispered in her ear before locking lips with her. With one more deep, hard thrust, Casey came, screaming into his mouth. Derek came shortly after, collapsing on top of her.

"Wow," Casey breathed out, closing her eyes.

"That was... great." Derek whispered, rolling off of her and landing next to her. Casey snuggled up to Derek's side as sleep suddenly overtook them.


Casey was awakened by the sun pouring into the room. Keeping her eyes closed, she tried stretching. She felt sore and something solid next to her. Eyes still closed, she played the events over in her head. Right when she got to the end of her memory, her eyes snapped open.

The solid thing next to her was a very strong, very naked Derek, still sleeping.


Well there's chapter one! Should it stay a one-shot, or should I continue it on to a multiple chapter story that takes them into college years?

Review, please! :)
