Casey's POV

I took one last look at myself in the mirror, I was wearing I tight jeans, might I add I think my butt looked great in them, and a red shirt that showed just the right amount of cleavage. I had my hair in nice loose curl, and I didn't over do the makeup, just the usual blush, mascara and a bit of brown eye-shadow. I had to thank my mom for my great skin, I didn't need to wear cover-up a day in my life.

"Casey you look great, Truman's going to love it!" My best friend Em said giggling.

"Oh my god! I completely forgot that Truman is going to be here any minute!" I added. In fact I had completely forgotten that Truman was coming at all. I don't know why I forgot he was my boyfriend after all. I took one last look in the mirror and then ran down the stairs with Em.

Derek's POV

I was sitting on the couch when Casey and Emily came bursting into the living room. I took one look at Casey and was blown away. She looked amazing, of course she always looked good, I've just never seen her dressed so..Well sexy. What was I thinking? Casey's my step-sister, she not sexy, and she needs to put more clothes on, I don't even want to think what's going to go through that scum bag Truman's head when he sees her. He better not get any idea's. Casey's a good girl, she would never sleep with someone as low as Truman. Would she? No of course she wouldn't, she innocent little Casey. But dressed like that people could get the wrong impression.

"Jesus Casey go put some clothes on!" I said trying to act disgusted.

"Last time I checked I was wearing clothes Derek!" She said clearly annoyed.

At that moment the doorbell rang. Let me guess who that is. Casey answered the door and before he could say anything Casey and Emily were already out of the door. I guess I should be going to the party had already started but I never arrived on time, I'm Derek Venturi, people expected me to be late.

When I got to the party I brought Casey her alcohol, and I opened my bottle of tequila. Gotta start the party the right way. "BODY SHOTS!" as soon as I said that there were 15 chick's lined up and ready to go.

Casey looked at me and asked "Can I go first Derek?"

I looked at her then said "You do know that I'm the one doing the shots and then I would pour salt from your stomach to just below your chest and lick it then with my mouth I would take a piece of lime out of your mouth?"

"Of course I know that. Now let's doooooooo it!" she had clearly already been drinking, but who was I to refuse her wishes.

Casey lied across the counter then took off her shirt. She was wearing a deep purple bra with black lace trimming. I'm not going to lie here, it was HOT! But being the respectable man I am I told her didn't have to take it off she could just life it half way up. She laughed and then said "BODY SHOTS!!!!" I couldn't help but laugh out loud. I took the salt and made a trail from her belly button to just where her bra ended. This seemed like it was wrong, she was my step-sister. But something inside me told me it okay. So I took a deep breath and then slowly licked the salt from her body, MY GOD did she ever have an amazing body, as I finished licking off the salt I downed my tequila, and then neared her mouth with my own. We looked into each other's eyes for a few seconds until I grabbed the piece of lime, and everyone started screaming. I looked up and there was Truman, he looked angry, but I just turned away and got myself a beer.

Casey's POV

That was so much fun, a little uncomfortable seeing as it was Derek, but I didn't mind at all. Truman looked at me, for a second I thought he was going to flip right out.

But then he opened his mouth and said "Casey, your never going to believe who's here. Its Vicky, I just seen her, she so stoked to see you."

"Really, are you sure she's not stoked to see you? She's the last person I want to see here Truman! You better keep your distance from her because so help me god if there's a repeat of the Toronto incident, neither of you will see the light of day again!"

"Whoa, Casey your obviously upset, but I'm not going to avoid her like the plague, she's my friend." He said clearly annoyed.

"well then enjoy the rest of the party Truman because you're flying solo for the rest of it! " I said and walked away, I didn't even wait for him to call after me, because at this point I really didn't care. I walked around outside for a bit until I saw Derek with Sam, Ralph and Amanda they were standing near the pool. I almost fell on my ass at the sight of what Derek was doing he was smoking a cigarette! And at that exact moment he turned and looked at me, he jaw almost hitting the floor.

"Casey! Please don't flip out! I only smoke when I drink. Don't tell Dad and Nora or I could kiss the Prince and rent money away!" He begged.

"I am angry Derek, but not at you for once. My trampy little bitch of a cousin is here, and Truman's going all gaga for her. Just give one okay?" I demanded instead of asking.

"What? You want a smoke? I don't know where this Casey came from, but I'm starting to like her." He handed me a cigarette. Of course I've never smoked a day in my life so as soon as I lit it up and inhaled, I coughed. That didn't stop me though, I kind of liked it, not the coughing but the smoking.

"Der, can I have a beer?" I asked

"Yeah sure, here Case." He handed me one of his beers. I never liked beer but at this point anything tasted good. Wow was ever hot out here. I wonder if anybody would want to go swimming. Shit I forgot to bring my bathing suit. I guess I could just go in my bra and underwear, it's not really a big deal, their relatively the same thing.

"Hey, does one of you want to go swimming" I said as I took my clothes off.

"That's it Macdonald, your going in." Derek grabbed and flung me over his shoulder and before I knew it both me and Derek were in the water. I couldn't help but laugh hysterically, Derek was still fully clothed and I still had my pants on.

" Venturi, say your last words!" I took his head and pushed him under the water I held him there for a few seconds but then he squirmed away. He swam under me and put me on his shoulders.

"Who's ready for water wars?" And before he even finished his sentence Ralph grabbed Amanda and they both jumped in the water, Amanda got onto Ralph's shoulder, and then we started play fighting. Amanda had the last push and I tumbled into the water. I couldn't help but grab her legs and pull her down with me. Until this moment Amanda and I have never said anything to each other, but for some reason we felt compelled to hug one another. We laughed and then Ralph spoke:

"Okay now it's our turn, Derek get on Casey's shoulders." We all laughed, but we were having a blast. Derek got on my shoulders and I could barely keep balance. It didn't really matter because Amanda had just as much trouble as I did. When we finally found out balance the boys started to attack each other, they were a lot more violent than me and Amanda. But this was fun as hell. I think this was the first time I had ever had fun with Derek, normally all we do it fight, but for some reason I liked this. I liked us getting along.

Of course Derek won the battle, I like to think it was all me, but we all knew that Derek was strong and Ralph stood no chance against him. When we were done "water wars", we all got out of the pool and we dried off, I suddenly had the pee REALLY bad.

"He can someone walk me to the bathroom, I don't want to go alone." I asked quietly.

"Come on case, I'll go with you, in case you see your cousin and decide to start a bitch fight. I wouldn't miss that for the world because that would be hot!" he said with that smirk on his face. I loved that smirk.

As we were walking to the bathroom, Derek grabbed my arm and turned me away. "The bathrooms that way Derek, what are you doing?" I was confused.

"Just trust me okay you don't want to go that way." He was angry he had that tone in his voice that I had recognized. The only other time I hear it was when we were at the party in Toronto…I whipped around so fast it made me dizzy. That's when I seen it, there he was kissing her. "What the fuck Truman! Seriously again! It isn't bad enough you did this to me once, but again, and with! Were through Truman." I turned to Vicky "And as for you, you little fucking skank, get the fuck out of here before I commit murder I don't give a fuck if you're my cousin!" Then I slapped her. The tears were coming I could feel it. I ran to the bathroom and locked myself in. How could this happen again? How could I have trusted him? Derek was right when he said Truman was no good. I was sobbing uncontrollably.

Derek's POV

"If you know what's good for your Truman, I'd get out of here right now, cause if I get to five and I still see your face, the cops won't be able to identify your body. One-two-thr.." Before I could even finish he was gone out of sight. Maybe he wasn't as dumb as I thought. Who am I kidding he was a fucking idiot as if he did that to…Casey shit where did she go. I found her in the bathroom, the door was locked, but I could hear her sobbing. Fuck, I don't do tears. This was going to be hard. "Casey it's me. Open the door. I'll bring you home.

"Derek?" She asked between sobs.

"Yeah Case it's me. Please open the door." I had never used this tone before, I was so caring. She unlocked the door but didn't come out. I opened the door slowly, and there she was, her head on her knees, with her hands covering her face. I did the first that came to mind. I sat beside her and laid her head against my chest.

"I should have listened to you Derek. You tried to warn me that he would never change. God why am I so stupid!" She was in a full fledge crying fit at this point.

"Look at me Casey," she looked into my eyes, her eyes were red and puffy tears were streaming down her face and her nose was leaking. "You're not stupid Casey, you're the smartest person I know. He's the stupid one, look what he just lost. The best thing in his life. Your smart, caring, forgiving, beautiful, I could go one for days. If he can't realize what he lost then that's his loss."

"You really think I'm beautiful? You're always telling me how ugly I am." She said quietly.

"Casey you're the farthest thing from ugly, trust me. Now come on I'll bring you home." I picked her up and carried her over to the cab. On the way home she fell asleep with her head on my shoulder. I couldn't help it, I wrapped my arm around her. When we got to the house I woke her up, and she walked straight into her room and went back to bed. I guess I should be doing the same seeing as it was 4:26am.

I was woken up at around 12:30 when Casey crept into my room and sat on the edge. She shook me lightly, and I opened my eyes to see here there with a cup of coffee in her hand, and then she extended her arms and gave the cup to me.

"Thanks Case, you didn't have to." I said honestly.

"I know, but I felt I owed you at least some kind of thank you. You were great last night Der. I don't know what I would have done without you. I know we don't get along, but when I really need you, you always pull through for me. And honestly last, night was a blast I had a great time. It was fun hanging out with you and being friends, not just your super annoying step sister." She said, and by the way she said friend I couldn't help but smile.

"I never knew how much fun you could actually be Case. You really surprised me. Your pretty cool, when you're not going all crazy on my ass, not that I don't deserve it most of the time." And with that she opened her arms waiting for a hug, I caved and gave her a squeeze. "Are you happy now?" "Yes" was all she replied before getting up and going downstairs. I got up and went straight to the shower I smelt of a mixture of alcohol and cigarettes, the combination were not very appealing. When I finished my shower I threw on some clothes and went downstairs. Everyone was gone except for Casey. She was standing in front of the stove and it smelt like bacon and pancakes. Maybe being nice to Casey had it's perks.
