A/N

Long time no see! Hello earthlings. Well, i've been absense due to exams. They suckkk. But I was thinking lastnight, and I just really want to do a fic with Cassie. She's in my OC fic remember? I need to update that.. Anyway, she's Blaine's sister and she's one year older. Go onto my OC fic and you'll see more. I ship her so hard with Sebastian omg. So this is a Seb/Cassie fic. Puhlease read! So, Sebastian is an evil character (and yes, he's gay, but in this fic he's straight and he goes to McKinley also) and stuffs. This fic is the darkest fic i've ever written. Its very... weird. I was going to base it on Grant's movie 'a mothers nightmare' omg I fucking LOVE. It's rather strange and some people may say scary. I love scary stuff though, mwuhahah. Anyway I decided against that idea, this is my own original idea. If you don't like dark, mysterious and strange stories, stop reading here. Without giving away too much, this is an abusive relationship story. It has a few twist's along the way though. I hope you guys like this story though cause I am actually in love with the idea. I'm gonna tie off any loose ends on stories I haven't finished, or that I lost my mojo for. Okay, here goes, hope you enjoy..

The good thing, Cassie noted absent mindedly, whilst flicking through the latest issue of 'vogue' magazine on a cold and miserable Thursday evening, about being Sebastian Smythe's long-term girlfriend, was the respect she got from everyone. Sure, she was a cheerleader, and he was a jock, she got respect anyway. But being his girlfriend, just gave her that extra topple over the edge. She and Sebastian were the it couple. Everyone admired them, everyone wanted to be them. Sebastian was the hottest guy in school, why did he choose Cassie to be his girlfriend? Cassie often wondered this to herself. She mused over it in class, in the shower, when she was lying awake in bed at night. She thought about it when she was in glee, listening to Mr Schue drone on and on, and when she was at cheerio practice, where Sebastian would often be watching her from the stands, 'perving' over her body, if you like. She had even asked him why he had picked her, one time. They were at his house, just cuddling. After sex. It just came out, she hadn't even expected a reply, not really. He simply replied, with a shrug. "I don't know babe, just know that I did choose you, and that's all that's important. Just remember how lucky you are to be with me, and don't question it."

Cassie had been a little puzzled at the reaction that her boyfriend had given her, but she didn't question him further. You did not argue back with Sebastian Smythe, even she knew that. She just nodded, and that was the end of it. That was months ago though, and it still played on Cassie's mind, even now.

She allowed it to creep into her mind as she finished reading the magazine, placing it on her bed. Standing up, she shook her head. She didn't want to let Sebastian control her thoughts, she didn't want anything or anyone to ruin her concentration on studying tonight, she had exams coming up. No matter how popular she was, school work was still important to Cassie. She wanted to go to NYADA with Kurt and Rachel, and she needed qualifications for that. Sebastian wasn't happy about her wanting to go to New York though. Sebastian wanted LA, and he expected Cassie to follow. Cassie didn't want that though, not that Sebastian ever listened.

Opening her laptop and sitting down at her computer desk to study, Cassie cleared her thoughts, she wanted to concentrate on studying tonight. Nothing or nobody else. As soon as she got online, an email from Sebastian automatically popped up. She groaned in frustration. He was obviously awaiting on her logging on. She was hesitant to open the email, but eventually did:

Hey Babe, you wanna come over? Entertain me maybe? Sebastian Jr misses you ;)

Cassie sighed once more, clearly he wanted sex. That's all Sebastian ever wanted. She quickly tapped out a reply before getting back to her work.

Sorry babe, can't tonight, busy. Sorry x

Considering she had only written a few lines of her work before Sebastian's name flashed up again, she was beginning to get annoyed. She rolled her eyes, clicking on the flashing icon.

I'm sorry? Did you just say no to me? Cassie, you don't say no to me. I thought I made that clear the last time.

As her eyes ran across the message, she immediatetly tensed. She replied almost instantly and gulped.

I know, but this is really important. Maybe tomorrow?

She didn't even have to wait a minute before another message came through, making that annoying, high pitched 'message' tone that rang in her ears for hours.

No, not tomorrow, now. You will come to my place now, and you will have sex with me. Is that understood?

Once Cassie clicked on the message and read over it, she regretted it. She looked down at her arm where a bruise lay. Not just a small bruise, a big, purple, painful bruise. She hated having to tell everyone what had allegedly happened to cause that thing. It was only a couple weeks ago, the image was still fresh in her mind.

*Flashback*

"Babe?"

Cassie stepped inside the cold, eerie janitors closet where she had arranged to meet Sebastian just hours earlier. Or rather Sebastian had told her she would meet him. She just agreed.

She was beginning to wonder if Sebastian was actually here, she furrowed her brow as she got no response. A few minutes later, he stepped out of nowhere, making Cassie jump.

"You're late.."

His voice was full of anger, you could tell. She just looked at him for a few minutes in complete silence, his cold eyes boring into hers. You could cut the tension with a knife.

"I know, i'm sorry, cheerio practice ran late an-"

Before she could reply, Sebastian grabbed her arm. She was instantly gripped against the cold wall behind her.

"S-seb, what are you doing?!"

"You're not ALLOWED to be late! I said meet me at 4:00pm, its 4:25! You kept ME waiting! That is NOT acceptable!"

He tightened his grip on her wrist, which caused her to yelp out in pain. She was fragile anyway, she didn't eat, her bones were weak. She didn't eat, not because she was insane and a bit mental, but because that was another one of Sebastian's silly rules. He stated to her that she had to be under 10 stone, otherwise he wouldn't date her. She loved him, so she listened. She never ate, and that kept Sebastian happy. She managed to lie to her parents about not being hungry, she put off meals and skipped lunchtimes at school. She was always with Sebastian at lunch anyway, they were usually having sex.

"I'm sorry! It will never ever happen again! I swear!"

Sebastian loosened his grip and dropped his hand, nodding once. Cassie looked down at her wrist, which still had his hand mark there. Not only was his hand there, imprinted into her skin, but a bruise was forming.

"Good, now we're gonna do it. Okay?"

Cassie barely had time to reply before Sebastian had his lips on hers, and was undressing her.

*End of flashback*

Cassie sighed in content, still staring at the bruise. She knew to listen to him, otherwise the consequence would hurt.

She shrugged off the intense feeling that was running through her veins, and stood up. As she grabbed her jacket and car keys, her phone buzzed.

Sebastian.

Opening the text, Cassie couldn't help but tremble slightly. Even his name scared her, that wasn't normal.

You haven't replied to my email, I take it as you're on your way. Good girl. I'll be waiting.

She sighed and shook her head in disbelief. To anyone else, this behaviour would be appauling. But she was used to it. Once she was outside, she unlocked her car and her eyes darted around the familiar neighbourhood that she had grew up in. She lived on a posh estate. Her family were insanely rich. Hence the reason her folks could afford to send Blaine to dalton. She stared at the house next to her's and reflected on life at that very second in time.

Why did she put up with Sebastian?

Wait, that wasn't even a question. She loved him. She needed him.

Cassie was pulled away from her thoughts as her phone bleeped once more.

Where the fuck are you? I told you, I don't like to be kept waiting.

She groaned and quickly replied.

I'm on my way.

She hopped inside her car, shivering at the warmth. The temperature change from outside in the freezing cold, winters night, to the warmth of her car was quite drastic. Shoving the car keys in and waiting for the engine to rev up, she got one more text.

Good, I have some slutty lingerie I want you to wear too. You looked hot in that last time. I told you I want to be entertained and I don't want to be disappointed.

Cassie rolled her eyes and placed her hand on the steering wheel, reversing out of the drive. She didn't even bother to reply. It wasn't worth it and she had to get Sebastian's as quick as possible. She groaned to herself, his texts playing through her mind.

She sighed once more, before driving off into the darkness towards his place, it was gonna be a long night.
