She couldn't take it anymore. They've been on this trip for only six hours. And he was already making out with some random girl. Why did Casey even feel this way? Did she have feelings for him? No, she couldn't. She didn't want to. I mean, he's her step-brother.

But why the sudden urge of jealousy?

She didn't know. And she didn't want to find out. They were in New York. For a "quality" family vacation. Yea, right. This vacation was going no where.

Especially if Derek was going to drive Casey insane the whole time. But they were both in for a big surprise. A surprise that included a night club, some tequila, and a steamy hotel room…

"Why are you so mad all of a sudden?" Derek asked Casey as they strolled behind the rest of the family downtown in New York.

"Why would you care?" She snapped.

"Just wondering." he answered. "But you might wanna get some extra sleep tonight. No one wants to see a cranky Casey tomorrow morning." The he increased his speed to catch up with the rest of the family. Leaving a cranky, yet jealous, Casey behind.

The sun shone bright and peoples voices were loud. A perfect day to walk around in New York City.

As the day went by, the day got dark. "Derek, Casey! We are all going out to eat and catch a movie. We might go shopping afterwards. Do you guys wanna come?" Nora called out to the two teenagers.

"No." they answered in unision. They sat on the large couch in their suite watching TV. They had to have to suites because their wasnt enough bedrooms in one. She the other suite belonged to Derek and Edwin as the rest of the family stayed in the other.

"Ok, just dont cause any trouble." Then they were gone. Derek and Casey watched TV for another twenty minutes then Derek got up and grabbed some left-over money that George left incase they got hungry and wanted to order a pizza.

"Hey, where are you going?" Casey asked him as he got up and walked towards the door.

"Out." was all he said.

"Out where?" she asked again.

"Clubs." he said annoyed.

"Why? To see whores and pole dancers?" she asked sarcastically.

"I wanst quite planning on that." he said squincing a little. "I'm just in the mood to get drunk."

"Oh, really."

"Yea, cya." He opened he door, trying to get away from his annoying, over-suspicious step-sister.

"Wait!" Casey called.

Derek groaned and turned back to Casey. "What?!"

"I wanna come with." she answered. A sly smile playing upon her lips.
