"You're so full of shit Derek." Casey laughed. "If you were really as hard as people thought you were you'd be out right now smoking, or doing drugs." Max leaned his head back on the chair and laughed silently. Casey surprised him sometimes. He loved the model-student side of her, but this was the side that he really enjoyed. But she'd never play it for him. Still, watching her get all worked up turned him on. Sitting on his lap, Casey was in the perfect position so that he could touch her intimately and no one would notice.

Casey looked down at her boyfriend in surprise who raised his eyebrows innocently. She could feel him getting hard beneath her as he smoothed his hands up and down her thighs. In a smooth sort of fashion, Casey decided to approach the situation like a secret, all the needed was a way to hide what Max was about to do. Casey lifted one of the large pillows of the couch and placed it over her thighs, immediately Max hand slid under her ass and up through her legs. Casey turned back to Derek to hear his reply. The aim of the game was to act normal.

"Well actually MacDonald," Derek said lazily. "A brilliant athlete like me can't afford to smoke." Casey smirked, "That's right Derek. You're still holding onto that dream of a scholarship, aren't you?" Derek ignored her. "And secondly, why would I need some shit to fuck up my brain to make me think I'm some kinda God when actually, my life is perfect?"

At that point Casey couldn't really give a shit. She leaned deeper into Max and pulled the pillow tighter around her as Max repositioned her sideways on his lap for a better angle. "Whatever Derek." She managed to breath for a reply, trying to end the conversation so she could concentrate on Max's fingers. The whole situation was kinda turning her on. Having other people in the room, she hadn't really thought about it. I mean, if they knew, that would be gross, but the fact that they were oblivious only added as an aphrodisiac. She could feel it cuming and resisted the urge to groan, biting her lip and burying her head in Max's neck. She couldn't help but move though. Her hips slid back and forth against her boyfriend very experienced hand.

She felt the first few spikes of pleasure round her body and couldn't wait to pay Max back in her bedroom later on when Derek finally left. Or maybe on the couch…

She was nearly there, she could feel the first wave coming.

Anticipation's a bitch.

She was so nearly there…

"Okay Dude, you really have to stop that."

Max stopped and Casey groaned in frustration. "What?" She heard Max say, innocent as sin. Derek sighed. "Look, I know what you're doing and honestly, the thought of you guys together makes me wanna hurl, so why don't you just get a room." Casey sat up, her face on fire. "God Derek, you're so insensitive!" Derek laughed in disbelieve. "I'm insensitive? You're the one letting your boyfriend get you off around your brother! Why don't you just go upstairs for fuck's sake. Get it over with."

"We were going to." Casey said through clenched teeth. "You weren't meant to be here." Derek laughed and sat up. "So what? Instead of you going at it in your room privately, you decide to come down here and put yourself on show?" Derek shook his head, "This has been a whole new side of you young lady. But I'm not that cruel, so I'm gonna go hang out in my room." Casey smiled at him, "That's the sweetest thing you've said all day Derek." But instead, Max lifted her off his lap and got up.

"Don't bother dude, I've got things to do anyway." Casey looked around surprised. "You're leaving?" He wrapped his arms round her waist and kissed her, slipping his tongue in her mouth to let her know he was still pretty excited at the whole thing. "I've got stuff to do, I'll come back later if you want." She walked him in the door and kissed him again before he left.

"Hey Max, call when you're coming round and I'll invite a girl over." He grinned and grabbed his crotch. "We'll have a slumber party." Max laughed and patted Casey's ass before closing the door. Something he'd started since she was voted best ass out of the footballers' girlfriends. She liked it.

Not one to be distracted Casey turned round to unleash her fury on Derek. "You don't have to be so gross." She shouted which made him laughed ecstatically at. "You're serious?" He said, jogging back down the stairs to continue the fight. He followed her into the kitchen and smacked her ass as she walked round the island. He dashed away from her when she tried to hit him. "Stop it Derek or I'll tell Max when he comes round later."

"No but seriously," Derek said, ignoring her threat. "What the hell was that today?" Casey grabbed a bottle of water from the fridge and said through gritted teeth. "Today was meant to be alone time for me and Max. Which, by the way you ruined!" Derek pulled himself onto the counter and laughed. "Lemme guess, your first time?" Casey looked at him quizzically. Derek raised his eyebrows at her and leaned forward. "Was he going to steal your virginity?"

Casey cocked her head sideways and smiled at him amused. "Sam never told you?" Derek sat back, not wanting to understand what she meant. "No…" Casey laughed and walked out of the room. "No way!" Derek called after her defiantly. "Your first time was with Sam?" She turned the Tv on and didn't reply.

Derek grabbed a Cola for himself and went out to join her. "You're serious?" She smirked. "Sam?" She said, "No." Derek shook his head. "Okay so you and Sam fucked, which by the way means he's been keeping secrets from me. It also means that Sammy's finally lost his virginity." Derek sat back, amazed. "And what about you? Sam was your first right?" Casey looked at him, disgusted, "Why would I tell you that?" Derek laughed, "Which means that he wasn't." Derek shook his head. "God Casey, you're turning into a closet slut."

Casey snarled at him. "When you're in stable and loving relationship Derek it's just the next step." She sat back smugly, "A mature person like myself is able to handle it." Derek raised his eyebrows in disbelief. "I was with him for two years!" She exclaimed, irritated by his judgement over her. Derek smirked in his arrogant way and sat back on the sofa. She was going to retort with a list of his Man-Whore ways when her Mom came bustling in with groceries. Nora asked for help unloading the car which Derek typically ignored and Casey typically jumped at the chance. "Thank You Casey, you're great." Nora said, throwing Derek a dirty look. "I wonder what she'd say if she knew what you're really like." Derek whispered as he walked up the stairs to his room.

Casey looked at herself in her bathroom mirror. Tonight had been so irritating; the whole family at the dinner table and then having to help Edwin with his homework had been such a chore. All she could think about was Derek and how he ruined her evening with Max. She hated it when she couldn't cum, it had plagued her relationship with Sam. He just wasn't experienced enough. And now she has a more than experienced boyfriend who's ready to take her anytime, anywhere and Derek has to go and ruin it. She was that pissed she ended up phoning Max's house and leaving a message for him not to bother coming over to hers that night. She knew they wouldn't be alone anytime and since all she wanted to do was finally fuck him, what was the point?

She thought about going to her bedroom and finishing herself off. She hadn't bought herself a vibrator just yet; she wasn't that into getting herself off, but she could just feel herself getting wet at the thought of cuming tonight. Not having to wait till the next time she saw Max.

Making up her mind that ti was an emergency Casey made a dash to her room but stalled when she found Derek standing just outside the bathroom. "It's just me." Derek said, smirking at her, like he was thinking dirty things about her. "Don't worry," she said disgusted. "I'm finished anyway." He walked in, taking her with him and closed the door before she could leave. "What are you doing?" She said, giving him a withering look. "What's your rush? I thought you could stick about for a bit and we could…talk." He bit his lip, looking at her suggestively. She pulled him away from the door. "I'm embarrassed for you right now." She said, walking into the hallway.

He laughed, closing the door after her. "Derek and me." She murmured, while brushing her hair on her bed. He wasn't hot. He was gross. But she would bet that he was pretty good in bed. She could see him walk out of the bathroom for her bedroom and tried to think of him as sexy. Something which made her laugh out loud. "It just doesn't work." She said. "In case you want some company Casey, my doors right open." He shouted from his room.

Casey looked at herself in the mirror. What was all this shit he was trying to pull, just to freak her out? Her reflection smirked at her while thinking dirty thoughts and she smirked back. "How far are you gonna go with this Derek?" Casey said from his doorway. Derek looked up from his computer in surprise, "I didn't actually think you'd take me up on the offer Casey." She ignored his comment, a habit which she had picked up from him actually and sat down on the bed.

"So tell me." Casey said suggestively. Derek waited for her to finish but she just stared at him arrogantly. "What?" Derek said, dipping his head in annoyance. "Tell me how you lost your virginity." Casey said, as if it had been obvious. "Er…no." Derek scoffed and turned back to the screen. "Come on Derek." Casey whined. "Would you rather go down for my Mom's dessert, or sit here and regale with me your biggest triumph's?" Derek's mouth twitched to smile, but he ignored her.

Casey lay back on the bed and pulled a pillow down in between her legs, something which Derek didn't mind seeing. "Who was it Derek?" Casey said, leaning forward feigning interest. "Was it Kendra?" Derek scoffed at her suggestion. "No you're right. Kendra would never have let you fuck her. She's too good for you." Derek looked at her unbelievingly. "Excuse me?" He said smoothly, "Kendra laid out for me whenever I wanted her too. In fact," he said leaning forward, "she wasn't that great. That's why I dumped her. I got bored."

"Fine," Casey said, pushing hair away from her face. "Was it Michelle?" Derek laughed out loud, "Hah!" Casey groaned. "Derek you suck at this Game!" Derek laughed, "Oh it's a Game?" Derek flicked off his computer and turned in the chair to give her his full attention. "Casey, I gotta tell you something about the games you play with me." He leaned forward and dropped his voice like it was a secret. "You're never gonna win."

"Derek I think I've told you this before, but you're so full of shit." Casey threw the pillow at him and got off the bed. She opened her mouth to say goodnight to him at the door and of course, tell him he was pathetic, but stopped when she felt him behind her. "Derek-" Her stepbrother slowly pressed her against the door frame and fitted his body against her back. "What are you-" Casey started, but he interrupted her. "What makes you think everything they say about me isn't true?" Casey breathed deeply, deciding there was no threat. It was just a game, just Derek trying to freak her out.

"Derek, I have something to break to you. You're not a God. People don't worship you." Derek's face was so close to hers, she could feel his breath on her neck and with his body was pressed so firmly against hers that she could feel everything. She held onto the door pane to steady herself as Derek slid his hand up her thigh. "If you gave me 5 minutes alone with you, worshipping wouldn't be an issue." Casey forced herself to laugh, she had to keep appearances. Still, it was hard when Derek hand was still smoothing up her leg. "In your dreams Derek" She whispered.

Hearing footsteps on the stairs Derek pulled Casey away from the door frame and shut the door quickly, replacing her against the actual door itself. Derek built himself up to an impressive height above her, something which she couldn't help but stare at. "I think you and me have missed an excellent opportunity here Casey, what with us living in the same house and all." Derek traced his fingers lightly down her arms so that she shivered slightly. He leaned in, bending his head sideways as if he were going to kiss her. "I mean, what with you turning out to be Casey MacDonald: secret slut and all, maybe you and me… we could have some fun."

Not wanting to be the one who backed down, Casey arched her back, pushing her body against his and regretted wearing a t-shirt to bed. Cleavage would have been so perfect in this situation. "I see what you mean," she said, slipping her hands round his neck, whispering now that their lips were so close. "Like us being brother and sister, but not really?" She made it sound like an epiphany; like they'd never realised they were step-siblings until just now, when blood-relation would have been such an inconvenience.

"Who knows," Derek said licking his lips. He breathed deeply, gripping her waist against his body so that she moved with his breath. Casey would never admit it but he was making her feel dizzy. "You might actually learn to like me."

Derek moved ever so slightly and brushed his lips against hers. Contact only lasted for a second but it left Casey's lips burning and her eyes wide in surprise. Derek didn't move, it was like he was frozen. Did he just kiss me? Casey didn't know if she could deal with what had just happened, was she meant to say something? Should they, god forbid, kiss again? She wanted so badly to just close the distant between them and… and wrap her legs round his waist. If it was anybody else she probably would have. Well, if it was Max. But it was Derek. She decided to act cool and pushed it to the back of her mind. Get out of his room: that was the best option.

"Or…" She said, moving her head away from him slightly. "Why don't we just go with old faithful? Agree that we'll probably never like each other. You'll take your grubby hands off me and I won't hurt you for been such God Damn pervert."

Derek's eyes widened for a second and then he jumped back, groaning dramatically. "Aw come Casey, I'm all ready to go and everything." She followed his gaze down to his crotch and smirked, catching his eye and seeing that he was just as pleased with himself. "Well you know what you can do with that?" She said opening the door, "Go fuck yourself." Derek laughed as she closed the door behind her and continued as she walked back to her room. Casey wasn't quite so amused.

She closed her bedroom door behind her and leaned against it, not wanting to believe what she knew was true. She could feel it in between her thighs and when she drew one finger across the bottom of her shorts she was soaked. "Jesus." She said, slipping her knickers and shorts off, embarrassed at how wet they were. She wiped herself with a tissue and ignored her clit throbbing against her hand, begging to be touched.

"How the hell did he do that?" She said, diverting her gaze from the clothes she had just stripped off. She looked at herself in the mirror. She looked…flushed…excited. Locking eyes with her own directly in front of her, Casey spoke to herself and hoped that she would listen.

"I'm so embarrassed for you right now."
