Derek POV

Here I am sitting in my room and I don't know what's happening. What's wrong with me? Why is it that every time I talk to Casey I just want to hug and kiss her? No! Derek! You can't think these kids of things! She's your sister! Well, technically, she's your step sister. That doesn't matter! Stop thinking this way! I suddenly hear a knock at my door that pulls me out of my thoughts. I look over at the door and there stands Marti. She looks at me weirdly. She walks over to me. "Smerek, What were you doing?"

"Nothing Smarti. What's up?"

"I'm bored, Smerek. Will you play with me?" She looks at me with pleading eyes.

"Can I play with you later?"

"NO! I want to play NOW!"

"Well, you don't always get what you want!" I yell at her. I'm just so fed up. I can't stop thinking about Casey. But, I know she will never want me and it's wrong. If I told her she would think I'm nuts and hate me even more. Then my mind goes back to Marti. I look at her and for the second time this week I see her in tears. I'm just so frustrated though I couldn't help it.

"You're mean!" She starts to run out of the room, but I grab onto her arm and bring her back into my room.

"Come here. I'm sorry. I didn't mean to yell at you a you Smarti. I just…. I…I'm sorry, but you know how I said I had grown up stuff going on?" She nods. "Well, the problems aren't really getting any better. I am sorry though." I look at her and she looks at me with a wondering face.

"What's wrong with Smerek?"

"Nothing…. Just stuff. Don't worry."

"OK, Smerek then I forgive you" She smiles.

"OK, now run off and I promise I'll play with you later." She runs out of the room and I go back to thinking. I blare my music and shut my door. I try to figure out how I could like Casey. She just so… perfect. But, she's my stepsister. This can't be good I love my stepsister. Did I just say Love! Oh no! What am I going to do?

About 20 minutes later, I hear another knock on my door. "Marti, I told you I would play with you later."

"It's not Marti." I hear Casey start. "Is something wrong?"

"Nope, what's up?"

"Um, I was just wondering if you wanted to go to a party with me tonight. It's in like an hour and we could go together. I mean like we could go there together and meet up with people there. You want to come with?"

"Sure. Why not? Wait. Are you okay to go out? I mean not like I would care, but still I was just wondering" Why did that sound so weird?

"Ah, of course I'm fine. I'm over Sam. I told you that. Let me just get ready and we can leave" She leaves.

Casey POV

I'm going to a party tonight with Derek! Wait, no he'll probably just go to the party and then hang all over girls. Wait, I shouldn't care, he's my stepbrother. Well, whatever he does it's fine. I'm like his sister he could never like me anyways. Not that I want him to like me because that would just be wrong. Right?

I go to my closet and pick out an outfit that will show I'm totally over Sam. I don't really need him anymore. I have Derek. I liked Sam, but he's history. I have Derek. I love him. Oh my god! Did I just say I love Derek! Oh no! And it's not like I can just tell the person I like, or love, them. He's my stepbrother. Why can't I get it through my mind?

So, I pick out a short denim miniskirt and a cute pink top. I don't want to look like a slut, but I want to look available. I walk downstairs and see Derek is already ready and waiting for me in the living room. "OK, let's go Derek! I'm ready!" He turns around and I swear I see him staring. "Um, Der, you ok there?" He comes back to earth.

"What? Oh, yeah I'm great. Hey, you look great, Case."

"Thanks. Well, let's go. Mom, we're leaving! Be back by 12!" I yell to my mom as we're walking out the door. We go into the car and my mind starts to wonder. Why did Sam cheat on me anyways?

"Hey, Derek. Um, I know you must know because you're his best friend, so I was just wondering, why did Sam cheat on me? What did I do wrong?" He looks over at me, looking like he knows, but isn't sure if he should tell me.

"How would I know? I'm not his best friend anymore after what he did to you."

"I know you know so just tell me Derek. I don't care. I just want to know"

"Fine! You want to know! He broke up with you cause he's an asswhole. He told me that he wanted someone more loose. He said you were too safe. God! No wonder why I punched him!" Now he looks angry.

"Oh" All I can say is Oh. I can't believe that Sam would cheat on me just because I didn't give it up to him. He is a real asswhole. I look over at Derek. He actually looks mad, like he cares that Sam was being an asshole. "Why do you care, though? I mean, you go around to girls and all you want is that. So your friend was just doing what you were doing. Why are you so against it now when you do it all the time?" Why did I just say that? Derek has been so nice to me lately. He's been all cute and protective. Ugh! No, he can't be cute.

"What? Ok, Casey I can't believe you just said that.!" Uh Oh, he looks even more mad. "I don't do that to girls. And FYI, I have never done that and I don't break up or cheat on girls just because of that. I mean I'm not the nicest guy to girls all the time, but it's different. It's you , Casey. You're my sister. No one does that to you. God! I can't believe you just.. Ugh!" The rest of the car ride is in silence. We get to the party and Derek and I walk in. He goes one way and I walk the other. I go down to the bathroom. I'm about to step into the bathroom when I hear a familiar voice.
