Clary ran into the bedroom Sebastian had given her and collapsed on the bed.

What have I done?! She thought.

"Oh God…" Clary muttered, shutting her eyes.

"God won't help you now, little sister." The door to her bedroom opened and closed.

Clary heard heavy footsteps coming toward her. When she looked up, her brother was smiling (almost innocently) and looking down at her.

Sebastian sat next to his sister. Clary diverted her eyes, refusing to look at him. The demon pushed a piece of hair from her face. "Clary" He murmured in her ear. Clary flinched away.

Sebastian stroked her cheek. "Clary, don't be scared. I won't hurt you." He cupped her face gently, turning Clary's face towards him. The demon leaned in a kissed her gently, his hands running up her back and into her hair. Clary felt a shiver run up her spine.

This is wrong. This is so wrong. Clary thought and she absentmindedly pulled away.

Sebastian arched an eyebrow. "If you want, I can go back downstairs and 'chat' with your boyfriend."

Clary felt a tear run down her face. Sebastian didn't miss a beat, he swooped in and slowly licked the tear off her face. Clary shuddered involuntarily.

"N-no, don't hurt Jace." Clary shook her head.

Sebastian looked at her, like really looked at her. His eyes roamed freely, but they never left the body that Clary was trying so hard to conceal.

"Okay, dear sister. I don't have much time tonight, so let's get started." Sebastian pulled a piece of rope out of his pocket.

"What's that for?" Clary asked, stalling.

"Well, I have an assumption you won't be cooperating so," He smiled devilishly. "Hands out."

Clary, wide eyed, stuck her hands out obediently. Sebastian began tying her wrists together, a bit harshly, and then proceeded to tie his sisters hands to the bed post.

"Sebastian." Clary gulped and began reasoning with her brother. "You don't have to do this." The demon continued to knot the rope.

"I can… I can be a server, a maid even." Clary told him.

Sebastian didn't stop tying the ropes. He just grinned and said "Fine, you can be a maid too."

Clary silently sighed. She had to face the facts; Clary was going to be Sebastian's play thing tonight. And probably tomorrow night.

"Maid by day, sex slave by night." Sebastian exclaimed. "Yes, I like that very much."

Clary had to use every will in her body not to throw up.

"Okay, finished. Go ahead, test them out."

Clary pulled at her wrists. They didn't even budge.

When she turned back to face her brother, he was an inch away from her. Without hesitation, Sebastian brought his mouth down on Clary's. At first, she melted into it, remembering the day in Idris when…

NO. Clary scolded herself. Do NOT think about that.

So instead, she thought of Jace.

Jace, the blonde boy who saved Clary from the demon poison that first day.

Jace, the golden eyed boy who she instantly fell in love with.

Jace, the Shadowhunter who made her so mad.

Jace, her boyfriend, downstairs in a torture chamber.

Clary felt anger bubble inside her and she aggressively pushed Sebastian away.

Sebastian, who was taken by surprise, fell backward and hit his head on the wall.

"You bitch." Sebastian cursed. Clary just stared at her brother, terrified. The demon stood and touched the back of his head. It came away dark red.

"You bitch." He repeated. Fear coursed through Clary. What's he going to do? Oh god…

Sebastian moved, quickly. He was on top of her, his arms on either side of Clary's head.

"What happened there? You were enjoying it and then–"

Clary cut him off. "I was not enjoying it!"

Sebastian's mouth twitched."Uh huh. Whatever you say." He swooped down and kissed her again but pulled away a second later. "What were you thinking about?" He asked her innocently. "Jace? Thinking about your boyfriend, Clary?" She felt heat rise in her face.

Sebastian barked out a laugh. "You were! You were thinking about Jace!" Clary squirmed under his weight. Her brother smirked. "You shouldn't be thinking about Jace. You should be thinking about me and ONLY me!"

"I do only think about you! I think about when you'll attack us again! When you'll kill someone else I love! When you'll come back and torture my boyfriend just to get something from me! A moment doesn't pass when I don't think about you!" Clary burst. "But when I think about you, it's not just you! It's about my boyfriend and it's about demons and it's about pain!"

Sebastian's face showed no emotion when he hit her. Clary barley got the word pain out of her mouth when Sebastian's hand flew across her face with an ugly smack.

Clary felt tears spring into her eyes. Sebastian looked at her. "Don't you ever talk to me like that again."

Clary closed her eyes, hoping she would just slip into a coma. She didn't.

Sebastian touched Clary's cheek. His hand slid down to her chest. Clary froze.

"Is this one of your favourites?" Sebastian asked, referring to the shirt. Clary shook her head slightly. It was just a plain black tee with a white stripe going across the waist.

"Good." The shirt and bra was then torn to threads and thrown across the room in two seconds flat.

Clary winced when the cold air touched her exposed skin. She opened her eyes slightly and saw her brother looking down at her with those demonic black eyes.

"Did Jace ever get this far?" Sebastian teased her. Clary didn't respond.

Sebastian fondled her right breast, nipping at it. Clary felt tears rushing into her eyes. Yes, she thought. Jace got this far. But because he's a gentleman we didn't go much farther.

Sebastian quickly grew bored of his sister's upper half and moved below the waist.

Clary gasped when Sebastian pulled a small blade out of his pocket. He slowly cut her jeans off her body, Clary wincing every time he accidentally cut her.

Sebastian tossed the torn jeans aside. The demon pulled his own shirt off him. Clary couldn't help but stare. Sebastian was tanned and toned, his muscles rippling at every move. Sebastian caught her looking and smiled. "Not so hard to think we're going to have sex now, is it?" Clary knew she was blushing.

Off came Sebastian's own jeans and soon they were both in only underwear. Sebastian grabbed Clary's upper thigh. He slowly trailed his hand up until it rested on the hem of her underwear. Clary's brother started to push her underwear down at an antagonizing pace. "Sebastian, please stop!" Clary cried out.

The demon ignored her and soon Clary had no clothes on. Clary watched as Sebastian's black eyes widened in delight. "Oh god." She heard him mutter. Clary's body was frozen and full of terror when Sebastian lowered his head, promising her she would enjoy it.

A/N okay if you were hoping for something sexier and more graphic just wait a few chapters, okay? Because ya know what? I'm a sick person and I ship Clebastian with all my heart… Maybe if Cassandra Clare wasn't scared to write a sex scene, I wouldn't have this disgusting incest desire. Ugh fuck my life.

So did you like this chapter? Don't forget to review! I love to read them. And who knows? Maybe if I love your review I'll thank you in my next A/N. Also please tell me if you ship Clebastian too.

Oh no... I'm missing the new episode of Good Luck Charlie. Lol jk. It's not a new episode :P

Ciao!
