Derek thought about his night. He had been on a date with a girl, Marley, or maybe Carley. It was hard to tell. It really didn't matter, the point was that she was blonde, big breasted, and easy. And it made Casey insane. He could tell from the look on her face when Marly/Carly showed up at their house earlier. And then, later, when he snuck her up to his room. Naturally, he had her moaning before he even entered her, and the entire time he fucked her he could see Casey's face, making that narrow look she gets when she's pissed off. He did feel a little bad for fucking these girls just to piss Casey off, but then he thought about the pleasure they got from it, and figured it didn't matter.
Casey climbed through her window and shut it. She took of her shoes and socks, and then figured, "to hell with it, might as well make it quicker" and took off all of her clothes too. She walked across the hall to Derek's room and walked through the door. She didn't even bother knocking.
"Yep, about 11 minutes. Five minutes there, one minutes of fucking, and five minutes home. Sam sucks."
"Fuck you, Derek. At least Sam has feelings." Casey spat at him.
Derek leaped off of his bed, grabbed her shoulders, and said, "Fuck you right back, Casey. I have feelings, it's not like it's my fault that whenever you're around they're feelings of nausea."
"You seem to be keeping your dinner down fairly well; maybe you're confused about the meaning of the word 'nausea'. It is a big word for you to use." She tried to push him away, but he grabbed her wrists. He kissed her, hard. She kissed him back, shoving her tongue in his mouth. The two of them battled for dominance, neither getting any further ahead of the other. He shifted her wrists into one hand and reached down to her breast with the other. She let a small moan escape her lips. She pulled his shirt off of him, and then his pants. He bent down and began to suck on her nipples. She moaned again, louder this time. He let go of her wrists and slipped two fingers inside of her. She bucked against him. He kissed her lips again, and then nibbled her earlobe. She reached down and began to stroke his member. Not wanting to wait for anymore invitation, he pushed her down onto his bed. He pulled a condom out of the package under his bed and rolled it on. He began to thrust into her. They were both moaning and moving in rhythm together. They both came at the same time. Derek rolled off of her and threw the condom away.
"I told you so. Sam can't please you like I can."
"Fuck you." Casey said, and then she left.
