Chapter Seven.

Casey woke up to light kisses on her neck, Saturday morning. She started laughing as she turned towards the object of her affection who was smiling down at her.

"Morning." she said as she kissed his cheek.

"More like great morning," Derek said pulling her closer by the waist.

It had been three months since they finally expressed their feelings towards each other. Mostly everyone at school knew about the two lovebirds, and surprisingly, every one of them took it well. Emily and Sam were finally thrilled that they were together. Marti, Edwin, and Lizzie were tired of seeing them trying to hide their feelings and were also happy for their older siblings.

As for when their parents were around, they kept it discreet. They would sometimes fight about any random thing they could think about, but most of the time, they kept quiet. They would play footsies underneath the table, or glance at each other, when they parents weren't looking. They didn't like keeping their secret from their parents, but they didn't know how else to go out on it.

"Derek it's already eight, go back to your room," Casey mumbled nuzzling her face in his neck. Derek groaned and kissed her temples.

"So let them find out," he challenged and Casey rolled her eyes. She tried to stand up, but Derek kept her down. Casey tried to push him off, but he rolled on top of her and began to attach his lips on her neck, making her giggle uncontrollably. He put his arms around her waist and continued to kiss her neck, and brought his lips up towards her jaw, then her cheek, and ended at her lips.

Casey moaned into his mouth as his tongue slid into her mouth as they fought for dominance. As they continued their passionate kiss, there was a knock on the door.

Casey pushed Derek off the bed, luckily for him he landed on his feet. He quietly and quickly ran towards her closet to hide in while she straightened out her clothes and opened her door to find Lizzie there.

Casey let out a sigh of relief as she pulled Lizzie into the room.

Lizzie looked around the room and turned towards Casey, "Derek?"

Casey pointed at the closet and then walked over opening the door, and out came Derek seeing Lizzie.

Derek grew much closer towards Lizzie since Casey and he got together. Lizzie mostly went to him when she needed help with sports.

"Hey Liz, where's Nora and dad?" he asked as he pulled Casey onto his lap. Casey instantly put her arms around his neck.

"Out with Marti. You should thank me, I told them I'd wake up both up," Lizzie said taking a seat on the chair.

"Thanks," they mumbled. "Anyways, other than waking us up, what brings you here?"

"Wellllllllllllllll… I kind of need advice," Lizzie said shifting in her seat.

Casey and Derek looked at each other and reluctantly nodded, "Go on," Casey said.

"Okay, so I need guy advice," she started but Casey cut her off.

"Don't date anyone like Derek," she joked and Derek scowled.

"You're the one to talk, who's dating me," he said. Casey just grinned and kissed his cheek.

"Anyways, on with my story. I like someone, and well I don't know how to go on it," Lizzie admitted.

"Edwin," Derek and Casey said together. Lizzie looked shock and tried to deny it.

"No, what are you talking about, I don't like Edwin."

Derek and Casey gave her the 'stop lying,' look and Lizzie huffed in defeat. "Okay so I do like him… how did you know?"

"Because you give him the googily eyes." Casey commented as she stood up from Derek's lap, to his dismay and went to her closet for a black collared shirt and denim mini skirt. Derek looked at her outfit that she laid out on her bed and reached for her hand, pulling her back onto his lap.

"Yeah, well you did that when you first liked Derek," Casey blushed and Derek laughed.

"Don't worry, Edwin told me the reason I ran into the wall was because I was checking you out," Derek soothed and Casey just laughed it off.

"Yeah, but you know he does like you," Derek said.

"He wouldn't," Lizzie replied and Casey and Derek shook their heads. "Serious?"

Derek nodded, "He comes to me most of the time and tells me how much he cares about you. Let's just say, if you knew how much I explained my feelings for Case to him, it's just like that when he tells me stuff about you."

Lizzie beamed and then thought for a moment, "So what should I do?"

"What do you want to do about it?" Casey asked nibbling on Derek's ear to distract him.

"I want to tell him."

"Then tell him, I know he's been dying to tell you." Derek said nibbling on Casey's neck making her close her eyes.

"Okay, you two bunnies, can you like stop for a couple of minutes and help me?" Lizzie asked jokingly only to receive a pillow hitting her on the head.

"Well, you guys' action isn't exactly the same as mine and Derek's, but I bet if you tell him how you feel, everything would be fine." Casey said as she walked towards Lizzie and hugged her.

"Thanks Case," Lizzie said hugging her back and walking towards the door.

"Hey what about my hug? And my thanks?" Derek asked acting hurt.

Lizzie looked at him skeptical. "Hug? What happened to your no hugging rule," she joked. Derek changed so much when he got together with Casey. He would still be his arrogant self, but he'd also be the compassionate kind of guy.

"You know I changed. So come here little one," he said pulling her towards her. Casey watched as her boyfriend and little sister hug. She smiled at seeing how Derek acted now towards Lizzie. She liked the way that he was taking responsibilities, and liked the way he made her feel good about herself.

After Lizzie left the room, Derek walked up towards Casey and pulled her by the waist. "So what do you want to do now?"

"Go eat, me hungry," Casey said acting like a five year old.

Derek laughed, and carried her downstairs, while Casey laughed for the most part. He made her pancakes, but he ate most of it when she'd stand to get a drink.

After getting a bite to eat, they went back upstairs towards Derek's room. Derek was changing into different clothes, while Casey was on his computer as they talked about doing something today. They didn't know exactly what, but something would come to mind. As they continued to talk, they heard a loud sound coming from outside of Derek's room.

"What the hell?"

THUD!

They stood from his bed and went outside and followed the sound. It was coming from Lizzie's room. Casey looked at Derek and Derek just shrugged. Casey opened the door quietly and looked shock when she saw what the sound was from.

Lizzie and Edwin were in an intense kissing fest as they shoved each other against the walls, to the table, to the bed. Derek couldn't hold in his laughed and roared out in a fit of laughter. Lizzie pushed Edwin off her and looked at her two older siblings that was clutching on their sides and falling on the floor laughing so hard that they felt like they were going to pee their pants.

"Uhhh… how much did you see of that?" Edwin said out of breath.

"Oh, from the shoving and moaning and groaning," Derek said laughing hard again.

"So I guess, everything went well, am I correct?" Casey asked, her laughs finally dying down.

Lizzie nodded and Edwin pulled on her waist.

"Good, because you guys suck at trying to hide your feelings," Derek said.

Edwin snorted, "You're the one to talk."

Derek shot him a look, and Edwin ran for his life out Lizzie's door. Casey and Lizzie just laughed at their boyfriends.

After a good ten minutes, Lizzie and Casey changed their clothes into descent hang out clothes. Casey wore the skirt and a collared top that she picked out earlier, while Lizzie wore some jeans that hugged her legs, and a tank top.

Derek and Edwin were walking up the stairs when they saw Lizzie and Casey come out of Lizzie's room. Both their jaws dropped and Lizzie and Casey laughed. Derek and Edwin looked at each other, and then moved towards Casey and Lizzie and pushed them against the wall and began showering them with sweet kisses. Lizzie giggled and wrapped her arms around Edwin while Casey turned the tables and pushed Derek against the wall and began kissing him. They were too wrapped up in what they were doing, that they didn't hear the front door open.

"Honey, I'm going to check if the kids are upstairs." George said as he began to walk up the steps.

George heard a moaned stopped on his tracks. He stared in shock; his two sons feeling up and kissing his step daughters. He cleared his throat and the teens moved away quickly, eyes wide, and had pure fear in their eyes.

"Downstairs, now! All of you," George stated as he walked away.

Lizzie, Edwin, Casey and Derek all looked at each other.

"Nice knowing you all," Derek mumbled as he grabbed Casey's hand and entwined it with his. She gave him a squeeze and he kissed her temples. "We're strong, right?" Casey nodded and kissed his cheek.

Edwin did the same and told Lizzie it was going to be alright, though his was trying to convince himself.

When they got down the stairs they all took a seat on the sofa. Nora came in and said hello, but none of them would look at her in the eye.

"Georgie, what happened?"

"Why don't they tell you," George said pointing at the kids.

"Kids," she asked.

They all looked at each other, and kept their mouths shut.

"What did you guys do?" Nora asked. "Liz?"

"Wellllll…" she looked at her mother and her mother gave her that 'you better tell me now or else' look. She shivered and looked at Edwin apologetically. "I like Edwin, and George saw me and him… well, kissing," she said bluntly.

Nora just stared at her daughter.

"Well… okay, but what does this have to do with Derek and Casey?" she asked turning to the two older teens.

Casey sighed. "Okay, well you know how I've been more lean back these past couple of months. And Derek getting his grades up. And you've seen the way we don't fight as much anymore?" Nora nodded, "Well Derek and I have been together for three months."

That was where Nora lost it, "What do you mean you're together? You all are siblings! This is wrong!"

"Actually it's not, because it's technically not incest. We aren't blood related, and we didn't know each other for all our lives," Derek countered.

"Still, what would everyone think about this?" George asked.

"Well, our whole school basically knows, and they kind of saw it coming already," Casey said and Nora shot her a look. Casey sighed and stood up, "Mom, did you really think when we started living here; nothing would happen with four teens that are attracted to each other. We didn't decide to live here, but it doesn't change the fact on anything. If we didn't know each other, and saw each other on the street, we would have most likely gotten together."

Nora sighed and sat on the coffee table.

"George and I saw this coming. Look, we're not going to make you guys break up, so don't worry," the four teens let out a sigh of relief and Nora and George just smiled.

"We'll just need time to be okay with it, get it?" four heads nodded.

"Okay, so rules," George said. They groaned and George and Nora rolled their eyes.

"One. Don't kiss in front of us. Two. If you guys break up, which we're not saying you will, please be civil in the end. And three. No sex." George's last statement was more towards Casey and Derek.

All nodded. "So you guys are okay with this?" Casey asked.

"Well we can't push you guys away, you would just rebel against us. So might as well let you guys be happy." Nora said kissing her temples.

Derek and Casey grinned at each other.

"I love you Case," He said kissing her cheek.

"I love you too Derek."

The End.
