Chapter One

Insulting Casey

It was a regular Tuesday morning at the Venturi-McDonald home. Derek was insulting Casey at the breakfast table.

Casey was wearing low cut jeans, and a blue polo which showed off her thin figure. Derek looked her up and down and then went at her. "You totally can not pull that outfit off. You're showing way too much of your chubby body." Derek laughed and reached over and pinched Casey's flat hard rock abs. Casey tried to hide her hurt face from Derek and succeeded.

"Whatever Derek. I don't care what you think of me." Casey snapped back,

"Sure." Derek shrugged not knowing what he had just joked about to his step-sister was something she was going to take to heart.

Casey left the house unnoticed skipping breakfast. At school she skipped lunch, deciding that she wasn't going to eat. She was going to show Derek that she could be thin like every girl he knows.

After school Casey came home and started doing her homework in her room. A knock at the door about 3 hours later interrupted Casey. "Hey Casey, dinner!" Lizzie yelled. Casey decided that she was going to skip dinner as well. "Lizzie, I don't feel too well. I have a really bad stomach ache. I think I'm going to go to bed now." Casey said trying to create a good lie. "Oh ok. I'll tell mom and George." Lizzie walked away.

The next day at breakfast Derek noticed that Casey wasn't there. He brushed off thinking that she was probably trying to look good for Sam, which he thought was stupid. She came downstairs yet again skipping breakfast. "Hey Case, aren't you going to eat?" Derek asked Casey. "Oh no I actually ate before all of you guys." Casey said lying yet again. "K, whatever." Derek replied not knowing what a dangerous thing Casey was starting.

3 days later Casey still was skipping meals. She had been skipping breakfast and lunch but not dinner. Dinner was too hard because her mom and George would notice she wasn't eating. She had decided to also become bulimic, throwing up her dinner every night. But this night Derek was getting kind of concerned about Casey. He decided to just leave the situation alone.

It was time for dinner and Casey was planning on eating it, but then purging later. She sat down at the dinner table and Derek walked in with Sam. Casey blushed, her whole family knew she had a crush on Sam, even Sam himself. It's so embarrassing. "Hey Casey." Sam said blushing as well. "Hey." Casey said giving a slight wave.

Casey was pushing her food around at dinner which Derek thought was weird. "Why aren't you eating your food?" Derek asked wondering what her answer would be. "I'm eating." Casey snapped back. Sam was watching Casey too and thought that her eating habits were pretty weird.

Up in Derek's room Derek and Sam were discussing Casey. "Dude, your step-sister is hot!" Sam exclaimed. "Ok…." Derek said kind of disgusted. "She's also acting weird. She like hardly ate her food at dinner." Sam said slowly. "Yeah." Derek said not really thinking it was that big of a deal. "Whatever." He said. "Yeah, I guess. She probably wasn't very hungry." Sam added. Derek nodded in approval.
