Well you guys asked for more so here is chapter 2 (the last chapter).

Disclaimer: I own nothing!

Dereks P.o.v

After Casey fell to sleep I kissed her forehead and closed her door. I was planning on sneaking out. I needed to teach Truman a lesson. So I waited until the everyone fell asleep and snuck out the front door. I took my car and went to Smelly Nelly's because I knew he would be there at this time. I went in and saw him sitting with two of the football players. I went up to him and well.. punched his face.

"WHAT WAS THAT FOR"! He shouted outraged, holding his nose.

"That was for hitting my stepsister". I told him in a surprisingly calm.

"What are you talking about? I would never hit Casey". He said still holding his nose which I hope was broken.

"Then how come she came home from your date with a bruised stomach"? I questioned.

"Because uh, um because we, uh-" I just cut him off.

"Because you hit her when you told her you were cheating on her"! I said punching him again this time in the stomach.

"AHH"! He shouted and now a crowd formed. But I didn't care. I grabbed Truman by the collar and started talking in a real low deadly voice.

"You will not go anywhere near Casey except for tomorrow to say your sorry and mean it, because I will be watching you. Then you are never going to speak, or look at her again. If I even hear you mention her once you are getting more than you got today. Also you won't tell anyone I even hit you and make up an excuse for your injuries, or else it will be much worse than what you got today. Got it"? I said that to him in my low deadly tone.

"Got it". He mumbled. So I had to ask again.

"GOT IT"! I shouted.

"I got ok got it". He said mad.

"Good not get outta my sight". I said and he ran away scared. After that I saw kids from our school just looking at me like I was insane but I didn't care.

"HEY! Stop looking at me please, Just go back to your whatever you guys were doing". I said to all of them and they listened. Then I left and went back home. When I opened the door I was about to go upstairs but then I heard something bad then getting caught by the rents.

"Derek, why were you outside"?

Getting caught by Casey.

"Uh well I was going for a walk, you know for some air". I said hoping she would buy it.

"Then why is there dried blood on your hand"? She asked me and I knew I was busted.

"Ok, well I went to Smelly Nelly's and punched Truman for hurting you and told him to stay away from you and to say sorry to you tomorrow". I said getting more quiet when I speak, because I knew she wasn't going to like it.

"DER-EK"! She yelled at me but I covered her mouth after that because if I didn't then I was going to have to explain to the rents about what happened.

"Case, keep your voice down you don't want to wake the rents right"? I asked her. She shook her head.

"Ok then keep your voice down". I said and let go of her mouth.

"Derek why would you do that"? She asked me and I thought that was a very stupid question but I mean we just became something so I didn't want to ruin that.

"Because Casey I just can't let someone hurt you. Look I know that when you and your family showed up that I was mean to you but I mean I really liked you and I knew I couldn't date you because your my stepsister and back then all I cared about was my rep so I was mean to you, but now I really wanted you to become my girlfriend and just don't care about my rep anymore. That fight is going to be all over the school tomorrow but I don't care. I really like you and just hope this doesn't mess up my chances with you". I said honestly while looking down. I don't think I can live without her. Then I felt something on my cheek. It was a pair of lips, Casey's lips.

"Thank you Derek. This won't ruin your chances with me at all. I knew that you did this to protect me and I'm somewhat proud of you but please don't fight anyone else if they do try and hurt me. I just don't want you to get hurt". She said.

"Casey I'm not going to get hurt and I can't promise that I won't do this again but I'll try ok". I told her.

"Ok, well lets get to bed, I just came down here for a snack and I saw you come in". She told me and started to head upstairs and I followed her. When we reached our rooms we said good night to each other and closed our doors behind us. I changed into my pjs and went to bed with dreams of Casey on my mind like every night.

4:39 AM

I heard a knock on my door, so tiredly I got up and saw Casey in her pjs with tears on her face and already I was awake.

"Casey what's wrong"? I asked her and told her to come in.

"I had a nightmare, may I sleep in here for the night please. I promise I will be gone by morning". She told me as more tears came down her face.

"Yeah of course, do you want to tell me about it"? I asked her.

"Uh sure. Um well Truman was hurting me again to the point where I was almost dead and no one was helping me". She told me cracking at some points and just started sobbing. I helded her closing telling her its ok, it was just a dream and then she finally stopped.

"Casey, I will never let Truman or anyone hurt you ok. I like you way to much to let someone hurt you". I said to her, really I loved her since I first saw her but I'm saying like so I won't scare her away or get crushed if she doesn't feel the same way.

"O-Ok Derek, I'm getting sleepy now". She said tiredly and I was sleppy too.

"Ok well lets go to bed ok". I said and she came in my bed and I tucked her in and kissed her forehead like I did earlier and we fell asleep in eachothers arms. Also, I got the best sleep of my life that night too.

A/N: Well it seems that Derek is out of character but this is still my first Life With Derek story so I'll work on it. Thanks for reading. Please review. Tomboy22.
