Chapter 13: It wasn't right with Kendra but its right with you

Derek and Sam talked for hours on end. Sam was remembering why he stuck by Derek's side when he thought that Derek was unfair. They gave each other a hug and Derek was on his way home. When he got there he was surprised to find Casey on the couch watching a re run of last week's hockey game. She was in his recliner eating popcorn.

"I see you started the party without me," Derek said sitting on the couch.

"So where did you go? You were gone for a long time and you left your cell phone." Casey said.

"Aww Case were you worried bout lil ol' me?" Derek asked fluttering his eyes.

"Well, knowing the weather conditions it's possible for you to be killed out there." Casey added.

"I'm alright…It's nice that you care anyway." Derek said. They sat there in silence for the rest of the game. When it was over he asked Casey to pass him the popcorn but saw that she was sleeping. He sighed. He went over and picked her up in his arms pretending that she was his bride. He knew that it was a little too weird but he did it anyway. Derek butted open her door and laid her down on her bed. It looked like she was having a bad dream and she clutched Derek's arm tightly. He looked down at her to see if she was alright and she had her eyes closed tightly. He brushed the hair out of her face and she awoke startled and panting. Her piercing blue eyes scared him. He felt weak looking at her. Then her eyes closed again. She was still sleeping.

Derek walked over to the door and closed it. No need to lock it because no one is here. He walked over to her and got in the bed next to her staring at her. He wanted her so badly to wake up and say that she wanted to be his girlfriend. He leaned over and kissed her right at the corner of her mouth, looked to see if she budged then kissed her on her mouth. Derek sensed her lips moving too. Her eyes opened again and this time she smiled. He stopped.

"Derek?"

"Yes?"

"I no we've been through a lot this past week. And I said that I couldn't be your girlfriend. I still would want you to be my first. I didn't willingly give it to Tommy and so I would willingly give it to you."

Derek was shocked and excited at the same time. He really couldn't believe that Casey just said that. But it hurt him. She didn't want to go out with him, but she wants to do it with him?

"So what are you calling this one time thing? Step-sib best friends with benefits?" He asked.

"I guess so, Casey said."

"What pushed you to make this decision? I know for sure probably around this morning you wouldn't want it at all."

"Well, I had sort of a bad dream that Tommy was here and he acted like nothing happened. He acted all nice to me, but then at night he came in my room locking the door and had his way with me again. But in the dream I felt something warm no me not cold and I saw your face hovered over me. You looked like you were some angel. And then Tommy disappeared and I felt these warm lips on mine and I opened my eyes and I saw you." Casey said.

"Casey I'm telling you right now that Tommy will never come near you." Derek said sternly.

"But Derek, I've heard what he's done to people, he broke this one guys ribs. What if he comes and he kills me Derek. What if I never get to experience anything? I never got to college, I never see you guys again, and I never had someone to make love to me." A tear rolled down her cheek and she turned her head looking out the window.

"I fucking promise you Casey McDonald. Tommy will die if he ever puts one fucking hand on you." Derek said now a tear rolled down his cheek. Casey turned back facing him and wiped the tear away.

"Just to make sure Derek…make love to me…please." Derek slowly, cautiously, took off his shirt and took off Casey's, she helped him with his belt and took that off as well. He caressed her bare skin making sure to do everything just right.

"Derek, I'm alright you don't have to go this slow." Casey said. Even though Derek was scared to go faster this is what she wanted so she was going to get it.

After a half an hour of it Derek collapsed on Casey dripping in sweat. His hair was painted on his face and her hair was so matted. It was great. At first he was reluctant to go inside her but he did it anyway. To what it seemed for him, she did enjoy it and that's all he wanted.

"Casey?" He asked?

"Yes?" She answered

"I love you. It wasn't right when I was with Kendra, but its right when I'm with you." Derek said.

Casey starred in his eyes. Who would have known that both teens had this emotion built up in side of them? Casey thought of this as potential energy. When energy is stored until further notice. And finally the energy was released. They felt for each other. It turns out Casey didn't want Derek to be a brother to her. She wanted a friend, a lover.

"I love you too." Casey said. I finally had sex to someone that I didn't feel guilty about. It sucks though. I want to be with her. I don't want us to use each other when our hormones are ragging. I want us to be able to openly saw that we love each other. Derek thought.

"So, umm what now?" Casey asked

"Wait… do you know how awkward it is going to be in school. I mean, we have to prove something false.' Derek said.

"No, we're not. Everyone at school thinks that we are going out, but we're not so there is nothing to worry about." Casey added as a matter of factly.

Oh right, I forgot

"Well, why don't we watch a movie or see what the weather is like." Derek said getting up out of her bed. He started putting on his clothes and so did Casey. He was downstairs before she was. He turned on the T.V and the weather was on. Something about the blizzard slowly dying and that by tomorrow it will be getting back to normal. So much for my vacation with Casey, but all the better to meet young Tommy and kick his ass. Damn, I can't wait for the plan. Okay let me go over this. I politely give up my room to him, set up webcam on my computer. We have to set up the monitor in Edwin's room and plant a video camera in Casey's room. Oh my god I cannot wait to but the mouse traps in my room. And the sticky tape on the floor so he can't get up in the middle of the night. This is going to be fucking great.

"Derek what are you doing? You seem to be thinking really hard over there." Casey said on standing right in front of him.

Oh nothing, just thinking about the best way to kill someone. Ha-Ha after we get done with him, he's not going to be able to pee. Penis…gone

"Shit Derek!" Casey yelled.

"What? What's wrong!" Derek asked concerned.

"We didn't use a condom!" Casey yelled.

Shit
