Chapter One

Casey woke early on a monday morning. It was to be her first day back to school, after Spring Break, of her senior year. and she wanted to get in the shower first, so she would actually have warm water. She yawned and shut off her alarm, mentally cursing morning. Although she would never admit it, the Venturi's had indeed rubbed off on her. What do you expect though? She had lived with them for over three years. Everyone had changed significantly over those three years. Casey for example was, not only no longer fourteen, but seventeen, semi popular. Thanks to, for the most part, Derek. Who had changed as well as the rest of the family. Maybe not as much, but still some.

Derek was now eighteen, who had been fifteen when the move happened. He was captian of his hockey team and had a full scholarship for it as well. His change had taken place in junior year. His role as big brother had come into play. This was when Casey was first breaking out of her grade-grubbing, klutzilla self. Guys had taken notice to her once she talked to more people besides Emily and wore clothes that normal high school girls wore. Step in the over protective step-brother. Sure they weren't the closest people ever and sure he was an ass, but after living with her for three years, he felt it was his right to watch over her, just like Marti and Lizzie.

Edwin was now fourteen. He was starting high school next year, the same year as Lizzie. He had just turned fourteen a couple months ago, but not early enough to have him in a grade higher than her. He had, thankfully, passed though his love for gas stage two years ago. He still held the honor of being a Venturi-Player, but always made sure no guys looked towards Lizzie. In anyway.

Lizzie was now thirteen, and had thankfully not taken Casey's route. She, of course, maintained good grades, but she did not work obsessivly hard for them. She was on her junior high's soccer team and was fully ready to take it on in highschool. Over the years, she grew out of her tomboy stage and developed a more fenimine side. Although her love for sports still remained a major priority in her life.

Little Marti was no longer six, but was now ten. She had just turned ten the previous week, happily leaving the single digits behind. She had grown out of her make-believe stage when 'Daphne' packed her bags and left the previous year. She probably had the best influences from her older sibilings. From Derek she was outgoing and popular. From Casey was studious, but not to the same extreme. She was also very loyal, and terrible at lying. From Edwin she was charismatic and very creative. From Lizzie she had recieven her sports talents and ability to read people with seconds of meeting them.

Although the five sibilings weren't the closet, okay so only Derek and Casey weren't close, they developed a sort of bond. They all had their share of tragiedies over the past three and a half years. Two years ago, George's ex-wife had passed, leaving the Venturi children upset for a few weeks. Barley four months later, Nora's ex-husband remarried and disappered, leaving Casey and Lizzie upset. Amoung many other tragides, the two families forced together, grew stronger as they became one family.

Casey heard movement in the room next to hers. That meant that Derek was either very roughly sleeping or he was indeed awake as well. She quickly opened her door and ran to the hall closet to grab a towel. She ran into the bathroom and turned on the shower, just as his bedroom door opened. She walked to the bathroom door to shut it. She saw him and smiled triumphantly, before shutting and making her way over to the shower. She stripped off her clothes and climbed into the hot shower. The hot water hit her body, slowly turning her tan skin slightly red. She let the water relax her muscles and she felt her self getting lost in the steam a bit. She picked up the shampoo bottle and began to wash her hair. Just as she began to wash her body, while the conditioner was soaking in her hair, she heard the bathroom door open and close.

"The bathroom is in use!" She shouted over the shower water and the sink water.

"Poor you." Came the voice of Derek. She then heard the sound of him brushing his teeth. She let out a groan.

"Der-ek!" She yelled out frustrated. She recieved no responce, but him spitting out the toothpaste. She rinsed off her body and proceeded to rinse out her hair. She shut off the shower water and stuck her hand out of the curtian to grab her towel. She heard Derek still by the sink. From the sound of it, he was now shaving. "Do you have any respect for privacy?" She said as she wrapped the towel around herself, not bothering to dry off. There was a pregnant pause before he spoke.

"No." He said, before continuing to shave. She let out another groan and made sure the towel was securly wrapped around her before opening the shower curtain. She saw Derek standing by the sink in his pajama pants, no shirt, and shaving. She climbed out of the shower and walked over to the sink. She really didn't care that she was only in a towel, after all he was her step-brother, and its not like she wasn't wearing anything. He was different than Edwin though. Edwin once caught Casey in a towel and took off to his room. Derek, however, didn't seemed to be bothered by her standing next to him. She pushed him over a bit, her skin connecting with his. She opened the medicine cabinet and took out her toothbush. She grabbed the toothpaste Derek left out and proceed to brush her teeth.

"Do you mind?" She said, trying to push him over again.

"I was here first." He said simply, but after a few moments.

"Actually I was in here first. Remember, I was in the shower." She said pointing her thumb over he shoulder at the shower. Derek mumbled something that she didn't catch, but before she could ask, he spoke again.

"I was at the sink first." He said, continuing to shave, although he was almost done.

Derek walked into the bathroom, knowing very well that Casey was in shower. She yelled at him and he made a simple reply before brushing his teeth. She heard her groan and whine his name. He would have made a smart ass comment there, had he not been brushing his teeth. Once he finished brushing his teeth, he went on to shaving. He heard the shower water shut off and saw her grab for the towel.

"Is she seriously going to get out of the shower with me in here?" He asked himself as she pulled her hand and towel back inside the curtain. She had definatly become more outgoing since she started to date Jake, around this time last year.

"Do you have any respect for privacy?" She asked, and he just replied with a simple no. He heard her groan again and open the curtain a few moments later. He saw her walked out of the shower through the mirror. She walked over to him and he expected her to yell at him, but instead she pushed him out of the way a bit. Her bare, wet skin hit his chest, but he chose to ignore it. There was something that made her different from the other two. Marti was his full sister, and he obviously saw her no other way. Lizzie, although she was a step, he saw her just as much like a sister as Marti. However with Casey it was different. He could not see her as a sister, although he experianced no emotional feelings towards her. He didn't see her as he saw other girls, he just saw her a a girl, who happened to live in the same house as him. Heck, he realised that she was related to the others, but he never felt that she was related to him.

"Do you mind?" She said, bringing him out of his thoughts.

"I was here first." He said, although it wasn't completely true.

"Actually I was here first. Remember I was in the shower." She said, gesturing towards the shower.

"How could I forget." He mumbled, before mentally cursing himself for saying it out loud. He quickly spoke again before she could ask him about it. "I was at the sink first." He replied cooly. She let out another groan, followed by his name.

"Der-ek!" She shouted, expressing both syllables in his name.

"You should stop that. People might think your having sexual thoughts about me." He said, smirking. She nearly choked on her toothpaste.

"That is so wrong." She managed to get out through the toothpaste. He finshed shaving before rinsing off his face. He took out his hair gel and looked into the mirror. He noticed that Casey was now standing by the toilet, applying lotion to her legs. The towel rised up her leg a bit as she applied the lotion to the lower part of her leg. It showed her bare, tan, upper thighs. He cursed himself, before grabbing his hair gel and leaving the bathroom. He walked into his room and slammed the door shut.

"Get a grip Venturi!" He yelled to himself. "What makes her so goddamn different! She is just as much my sister as Lizzie is." He thought about it over and over in his head and he threw some clothes on his bed. He heard her bedroom door shut and quickly took the chance to finish up in the bathroom.

Preview of Chapter two

"I saw Jason getting pretty comfortable around you." He said looking at Casey.

"What?" She replied, not sure what he meant. They were almost to the classroom door when he spoke again.

"You are my girlfriend. Thats means you are off limit to other guys." He said angerly.

"We were just talking." She said, placing a hand on her hip.
