A/N: Okay, so I finally edited it. Thanks to x-sara-x for correcting me on the drinking age! And I fixed where I had apostrophes instead of quotation marks. Dunno why they were there in the first place.

I would also like to apologize for the incredible OoCness in the last two installments. It just happened that way. I hope you guys like it anyway! :)

A Little Game

Oh. My. God.

I just slept with Derek.

I don't mean like: oh, I just fell asleep beside him in the living room. I mean hot, steamy, sweaty, passionate sex - in the gym... behind the bleachers.

Okay, not exactly what I had imagined my first time to be like, but, wow. I keep thinking about how soft his lips were. And how perfectly our bodies fit together.

Shit. I just slept with my stepbrother. Shit.

Earlier that morning...

"Derek! Give that back! Now!" Casey shouted. Derek had managed to, once again, get a rise out of her. It was so easy for him now. He could probably just breathe near her and she'd turn red in the face.

"Make me," he said, smirking.

"Derek, just give me the freaking cereal!" She was practically seeing red now.

"No! You need to watch that non-existent figure of yours, anyhow."

Casey let out a scream of frustration before jumping on him, knocking both to the floor. Reaching with one arm, and using the other to keep her balance on him, she barely grasped the box. Smiling triumphantly, she pushed off of him with her hand on his chest and poured out her cereal. Derek hopped up just as quickly and took the cereal from her again. She just shrugged, having already fixed her bowl and munching away.

Derek fixed his own bowl and the breakfast turned into a silent competition of who could finish theirs first. Eyes in glare-mode, spoons at the ready, they began the race.

Derek won.

Casey shot daggers at him as she sat in the passenger seat of his car. Derek merely wore a triumphant, cocky smirk the whole way.

While in the car, Casey changed the station. Derek's jaw dropped and he changed it back. Casey put it back to what she had put it on. Derek put it back. Casey put it back. Derek put it back. Casey put it back. They continued this for five full minutes before Derek finally just turned off the radio. They drove the rest of the way in a competitive silence. Neither of them gave in.

Casey marched over to her locker, keeping the competition going, even though Derek wasn't. He was over at his locker, flirting with some random blonde girl. Emily came up to her locker and started babbling on about the latest break-ups and make-ups. Casey sighed; she always has something to talk about.

"Em, I've got to get to gym. I'll talk to you later?" she stated more than questioned. Emily looked a bit startled by this, but nodded her head anyway. Casey walked on into the gym and put on her clothes.

"Coach Higgins, what exactly are we doing today?" she asked. She just wanted to get it over with.

"Oh, hullo Casey. This is kind of a random day. You can play basketball, sit on the bleachers, or jump-rope," he said kindly. Casey nodded her head distractedly, already heading to the bleachers. She just decided to watch everyone play around and converse amongst themselves. Unfortunately, she had managed to sit in front of Derek's game of basketball. She just leaned back and relaxed, thinking of random things that came to mind.

She was shaken out of her stupor when a basketball almost hit her in the head, and it would have, had she not moved. She sat up and grabbed the basketball, glaring at Derek. He was looking at her, smirking, waiting for her to give him the ball. She just walked down the bleachers and began to dribble once she was on the ground floor.

"So, I bet you think it's funny, don't you?" she demanded.

"Hell, yes. I thought it was hilarious," Derek replied.

"Fine. What do you say we do a little one-on-one, hmm? Me against you, you against me. None of your little buddies to help you out," she proposed with fake casualty. Derek looked around at his buddies.

"Whatever. Just give me the ball. Go back to the bleachers."

"What? Are you chicken? Afraid I might actually beat you?"

Derek scoffed, "Fine. Let's go. First to twenty."

Casey stood in front of Derek, letting him have the ball first. She bounced it to him, "Check." He bounced it back to her, she to him.

They began to play.

Fifteen minutes in, it was a tie: ten to ten. Casey had the ball. Coach Higgins blew the whistle, signaling that it was time to go to the locker rooms. Casey and Derek didn't stop.

"Hey, guys, it's time to head in," Coach Higgins said and went into his office. By now, everyone had retired to the locker rooms and was getting ready for class.

"C'mon, Casey. Just give it up. You know I'm going to win," Derek said smugly.

"You wish," she said. Derek went up to block her and got extremely close. He smirked when he saw her muscles tense up and then relax. He grabbed the ball and made the shot. Casey caught on and did the same to him. They continued with this; Casey blocking Derek, getting close, make the shot; Derek blocking Casey, getting close, make the shot.

When the score was nineteen on nineteen, Derek and Casey were getting rough. Derek had the ball, and Casey went up to block him. Only Derek dropped the ball and grabbed her. Casey looked shocked, but didn't move to pull away. He kissed her roughly and took her behind the bleachers.

Coach Higgins came out to see if they had ever went in. All he saw was a rolling ball.
