Disclaimer Dye-my-hands-yellow is too busy drooling at the moment to care about me not owning Life with Derek.

When Derek pulled in the driveway Casey ran up to the door and unlocked it swiftly with the key. He got out, confused, hoping that she wasn't mad. Derek couldn't see what he could have possibly done this time. His hand reached out and gripped the doorknob, but when he turned it, it was locked. Through the window he could see Casey smirking and laughing. He smiled. She was still happy.

Casey unlocked it and when he opened it he saw her running up the stairs. This was definitely a side of Casey he hadn't seen before. She was being…playful. Derek turned and locked the door, then slowly walked upstairs.

Just as he was about to turn into her room, she popped out of the closet and jumped on his back causing him to stumble. He fell forward and luckily landed on her bed. She was straddled atop his back. Derek groaned painfully into her mattress.

"I win."

"I didn't know it was a competition."

"It's always been a competition."

"Well in that case." Derek forced himself up causing her to yelp and wrap her arms around his neck. He reached his hands back and started tickling her. She tried to hit him, yelling 'that's not fair!' Casey got off of him and straightened her shirt out. He took advantage and flipped her onto the bed. Again she yelped. Derek looked down at her and smirked. I have to make this last. With other girls it doesn't last, with her it has to. I want it to. "Casey, tell me you want me." She furrowed her eyebrows.

"I want you?" Derek shook his head yes. "I want you Derek." He smirked.

"Tell me you only-"Casey interjected him.

"Tell me you want me."

"I want you Casey." She smirked at him. He sat down on the bed, and put his right hand on her other side so he was leaning over her.

"Derek." She managed to whisper out. "I want you." Derek leaned down and starting kissing and nibbling on her neck. He lifted her in his arms and took her to his room, still biting onto her neck. I'm much more comfortable in my room. Casey was a bit confused but before she could question him he closed her mouth with a forceful kiss. Her lips willingly parted and their tongues battled for dominance. When Casey had gotten into the rhythm she turned him on his back and straddled him.

An erection grew instantly in his pants, and he sitting on top of it made him groan. She came down and bit his neck hard. It caused him to bite his lip, but oddly enough it turned him on even more. Her hands were tangling themselves in his hair and he took his hands and softly scratched them down her back. Casey slightly arched with an odd expression on her face.

Derek tried to flip her on her back but she struggled against him. They ended up on the floor, with Casey on the bottom.

"Get off." She said frustrated. He got off of her. Casey stood and was having an obvious struggle with herself. She turned to leave and took two steps, but Derek had taken three, and when she turned back he was right there in her face.

After a brief pause Casey and Derek tackled each other at the same time, but Derek won by pinning her against the wall. As he kissed her she tried to take his shirt off. When it got to his neck he took it off the rest of the way, and then took off her shirt without wasting a breath. Derek gripped on her sides, his thumbs placed just above her navel. Her hands were on his back, gently pushing him closer. She obviously wanted more.

Derek was kissing down her neck and on her breast at the rim of the bra. She quickly took it off and he didn't hesitate kissing on one and holding the other in his hand. Casey suddenly pushed him toward the door and kissing down his chest, and as she got closer to his pelvis she began to unbutton his jeans. Derek became uneasy. He wasn't sure if she should go down on him. She ripped down his pants and boxers at the same time, and before he could protest she put all of him in her mouth. His head hit the door and his hands tried to grip at the mirror.

Casey took passion in everything did, and he was glad that this sort of thing was no exception. At first he could tell she was uneasy, but when he let out an uncontrollable moan she seemed to gain confidence. He could fill himself nearing release but refused for it to end so quickly. In one swift moment she was on the bed and her pants and panties were flung to the side. The speed of him left a shocked look on her face but when he started kissing on her pelvis she sucked in her breath.

As he swirled his tongue her hips attempted to move with him.

"Derek." She managed in a heavy breath. "That's not what I want."

"What do you want then?" He asked, looking up.

"You." Derek thought for a moment then smirked. He lifted himself up so they were face to face. While staring intently in her eyes he reached underneath his pillow and grabbed a condom. An obvious shiver ran through her and she grabbed it from him, and before he could do anything he was on his back. This time he didn't fight her.

She struggled to open the condom and he just laughed in amusement. Casey glared at him when she finally got it open. Her face changed back to it's sensuality and she slowly slipped it over his member. Derek couldn't resist running his hands up and down her entire body. Casey pulled out her ponytail and lowered herself onto him. Her head tilted back more as the depth it was in her increased. She brought herself back up, and lowered slowly again, moaning into the air.

Derek was squeezing her hips, knowing that at the moment he had no control. She came back up slowly and he jerked himself quickly into her as she rose. Casey gasped and he lifted her and stumbled against the wall, again.

He started slow, then got quicker. Her legs squeezed tighter around his hips and her hands tightened on his hair. Derek was pressed hard against her, and she breathed uneasily into his ear. He went deeper into her and she moaned loudly into his ear. An uncontrollable grunting noise came rhythmically out of him with each thrust he put into her.

Casey's hips started to curl back and forth with his thrusts and she whispered into his ear.

"Go faster, I think." She struggled to keep a moan in, "I think I'm going to cum." Derek smirked and complied. As he pumped harder and faster she let out all moans and so did he.

The air became increasingly hot and heavy, and after Casey let out a last moan she relaxed. Derek came seconds later.

They remained in that position, catching their breaths, looking at each others eyes. It was the most pleasurable sex he had ever had. Nothing any girl had done for him came close to that.
