A/N: Graphic violence/incest ahead!

She woke with a start. Her head turned back and forth and she observed that she was in the finished basement of the house again. Her hands were still chained and Sebastian had put the special rune on her that made her unable to walk fingers were numb and she realized what had woken her up. She'd had a dream, she'd dreamed of twin ivory thrones and blood and death. She shook slightly, afraid that Sebastian with his sister at his side he would be unstoppable. She wanted to turn on her side but because her hands were chained that was impossible.

She needed to go to the bathroom and Sebastian was probably upstairs dreaming away. "SEBASTIAN!" She howled. She called for him again and waited. Soon enough she heard the floorboards creaking as he made his way down the stairs and she sighed.

"What's wrong?" He groaned. She thought she vaguely heard birds chirping.

"I have to go to the bathroom."

"Fuck ok," Sebastian started doing the binds on her wrists and legs. He picked her up and he brought her to a small bathroom that was on the other side of the basement. He dropped her on the toilet and stepped outside.

He made her bed again and looked at the clock, it was 5:13 am. Good grief. She called him and he picked her up and carried her back to bed.

Clary was scared what the morning would bring. Would he rape her again? Was it even rape at this point? She was so fucked. "I'm cold." She grumbled.

He laid her down on the bed and tucked her in, "I'll get you another blanket."

Should she thank him? "Thanks," She said begrudgingly. He disappeared into a closet and came back with a fluffy down blanket. He put it over her and sat down on the edge of her bed and started re-doing her binds. "I'm going to crash here, I have to be up in two and a half hours anyway."

"That's early." She said as he finished up doing her bindings.

"Shh." He said as he curled into her side.

When Clary woke the next morning she didn't know what time it was only that Sebastian wasn't there. She remembered him saying he was having an early morning so she shrugged it off. Still, she was hungry and wanted to put something on other than the sleazy teddy she was wearing. She called out for him, "Jonathan!" But to avail, she didn't think he was home as she couldn't hear his footsteps upstairs. She supposed spending the day in bed was… better than what they'd gotten up to yesterday.

Hours past, she began counting the ceiling tiles, the number of DVDs in the entertainment center. She figured it had to be mid afternoon and she was getting really hungry and thirsty, not to mention she needed to use the bathroom again.

Finally, she heard footsteps creaking around upstairs. A fleeting part of her hopes that it's Jace, and that he's come to rescue her but her hopes are dashed when a bloodied Jonathan begins the trek down the stairs.

He stops in front of her bed and shrugs lightly. His right eye is black and blue, he's got cuts and scrapes on his face and it looks pretty bad. "Could you give me a healing rune?"

She knows why he's asking, her special gift of rune creation makes her runes especially powerful. He needs a healing rune and she needs food, water and a trip to the bathroom. "Get me some water first. You left me here all day unable to move."

He bites his lip and she wonders if he's debating about apologizing. "The mission I was doing this morning ran late."

Clary scoffed. "Looks like you got your ass kicked."

"You might not be saying that if you saw the other guys."

"Guys? More than one person did this to you?" There was a slight hint of… curiosity in her voice.

He sighed. "You know I can't tell you anything… yet." He handed her his stele and exposed the iratze on his forearm to her.

She took the stele and paused, she could draw a portal and get the fuck out of here in an instant. He was sitting right there though surely he wouldn't allow her to escape…

She sucked in a breath and drew the iratze on his forearm. She closed her eyes and handed the stele back, hoping her eyes weren't shining with tears as she felt her eyes burn. She felt like he was taking over her will to be free. He could never take her will to live but she knew something was changing inside of her.

She watched and saw as the bruise on his eye turned from nearly black to a yellow-green color. His cuts and scrapes knitted themselves back together and she wondered what Jace would say to right now… that she was a traitor and shouldn't be helping her brother. Still, she hadn't had much choice in the matter. "Please help me now," Clary begged him.

He undid her binds and carried her to the bathroom. He waited for her outside the bathroom and when she hollered for him he went and got her.

When they went upstairs she noticed she was staring directly at Phaesphoros, strapped to Sebastian's back. "Is that Valentine's sword?" She asked him

"Mine now." Sebastian scoffed.

"You didn't like father did you?" She said as he sat her down at the table and started making food for them.

"I thought that was pretty obvious."

"It was, it's just that I never understood why he beat you."

"It's not something I really want to talk about." Sebastian snapped

Clary sighed. She'd been here going on three days and it felt like much longer than that. He was buttering bread for grilled ham and cheese sandwiches. He assembled the sandwich and turned the gas down.

"Seraphina -"

"It's Clary." She snapped harshly at him.

"Actually, it's Seraphina," Sebastian said, rage growing.

"You're such an asshat!" Clary said, her own rage growing and she did not in the least care that she didn't have the use of her legs. "Don't fucking talk to me."

The sandwich Sebastian had been grilling was starting to smoke due to lack of attention. He turned his back on her, tossed the sandwich in the bin and started on a new one.

"Sebastian please tell me why I'm here…" She whimpered.

He buttered one side of a piece of bread and stuck it in the pan. The sandwiches were going to come out like shit no matter what he did.

A heavy silence followed in the moments following. When the sandwich was done he scooped it onto her plate. "Eat."

He started on his own sandwich and she started eating.

The next several minutes were very tense. Sebastian finally had his sandwich done and he sat down and ate it.

They didn't say anything to each other for a long time. There was a book on the table, Sebastian picked it up and started reading it. So this was how she was going to spend today? Sitting in silence?

After about an hour of sitting there, staring at her brother she wanted to get up. "Sebastian, can I go back downstairs? If we're just going to sit here then I'd rather go downstairs and sleep until you want to rape me again."

He looked up at his book. "What if I don't want to rape you?" He put a scrap of paper in his book to mark his place.

"What are you talking about?" Clary said, mildly bewildered.

"Well, what if I wanted it to be consensual?"

"I absolutely hate you, Sebastian." Clary breathed. She sounded tired when she said it. She knew why he was asking this. She'd moaned his name several times the other day when they'd fucked.

He smirked at her and took her chin between his thumb and forefinger. "You like it, you like it when I fuck you."

She pulled harshly out of his grasp and averted her eyes. "We've only done it once! Sebastian, you know every shadowhunter in the world is looking for us, don't you want to do something to stop them?"

"No," Sebastian said simply. "I have an army of endarkened shadowhunters to do that for me. I have a mission tomorrow but is it really that bad to spend a little quality time with me?" Clary couldn't be sure but he looked hurt.

"Do you really consider this quality time?" Clary said shortly.

"It could be? We could go outside again?" Sebastian suggested.

"It's freezing out I bet. This is the north, Sebastian." She looked out the window and saw it was snowing. "It does snow a lot here."

"It does." Sebastian agreed. "My book is getting pretty boring so I would be happy to go outside with you and throw snowballs at you. Or perhaps less wholesome activities are on your agenda?"

"Don't be disgusting Sebastian." Clary snapped.

"Is that what I am to you? Disgusting?" Sebastian asked.

She wasn't sure what to say. She was extremely angry with him for fucking her until she was sore the other day… but it wasn't exactly his fault that he had demon blood was it? And that's what was causing this, wasn't it? If he was just a regular shadowhunter he wouldn't be having these feelings, would he? "No. I'm just frustrated. Jace is probably worried out of his head."

"Jace knows you're with me," Sebastian said.

"How?!" Clary exclaimed. "Is he coming for me?"

"Of course he's coming for you but he's going to have quite the time of finding you. This place has wards."

"What kind of wards… exactly?" She said, trying to curl her body closer to him and placing her hand on his arm.

"Well, wouldn't you like to know!" He said with a laugh. Dammit, she'd thought she'd had him there.

He got up from his place and something fell out of his back pocket and landed on her foot with a thump. "Ow-" He was already turning to see what it was that had dropped but she was faster. He had dropped his stele and she could see freedom right in front of her eyes. She leaned down and swiped the stele off the floor and grasped the stele she made the rune for a was expecting a portal to open up in the middle of the dining room but nothing happened. He stood there, putting their dishes in the sink. The whole thing was extremely anti-climactic. She'd been expecting her rune to open a portal and she could just leave here as a free woman. Sebastian began laughing.

"Stop laughing!" She screamed at him.

"You think I didn't know you'd try to use the rune power and open a portal to God knows where?" Sebastian said, still laughing, a manic glint in his eye.

"Sebastian! God damn you!" She threw the stele at his head but he caught it.

"Eventually you're going to want me to trust you and that day isn't coming anytime soon. Don't you want me to let you out of this house? Someday you're going to want clothes or to do something other than going in the back yard. I have to know I can trust you for that."

She stood up of her volition and screamed, "I hate you!" She realized she was standing. She had broken the rune that bound her legs.

She lunged at him, screaming, "Let me go! Free me!" and hitting him over the head.

He didn't fall when she put her full weight on him. He staggered, and re-balanced. Trying to peel her off of him. This was their first real fight and as Clary pulled back her tiny fist to punch him in the nose but he ducked her punch. He was so fast.

"Sebastian! By the angel!" She bashed him over the head with a plate from the sink.

Until this point he hadn't really tried to fight her back but now she knew she had angered him. Maybe he was trying to get her to trust him for real and maybe he thought the best path to that was not hitting her when she hit him. This time they did fall to the ground. Sebastian's white blond hair was littered with flecks of blood now. Clary had completely forgotten but Phaesphoros, the massive sword, was strapped to his back. He wrestled her so she was under him. With horror she notices he's hard, his dick is pushing into her thigh. He catches her by the throat and holds her down, cutting off her air supply. "Little sister, if you ever put your hand on me in anger again, I will make sure you lose the hand that touches me." He said in a deadly calm voice.

She spits in his face, hitting his eye. "I fucking hate you!" She snaps. He wiped the spit out of his eye and growled low in his throat at her.

"If you hate me so much then I might as well do something to be worth your hate." He pulled up her nightgown, pulled down her panties and released his hard length.

"No Sebastian!" She screamed at him.

"Yes, little sister!" She watched as he lined his hard cock at her entrance. There was a little voice at the back of her head telling her to wave the white flag, tell him she submitted to him. A slightly louder voice was telling her that Sebastian was particularly well endowed. And the loudest voice in her head reasoned with her… was sex such a bad punishment?

He pushed into her and she wanted to scream. It's not that it didn't feel good, she was just tired of fighting him. No matter what she did, no matter how nasty she got this was the one time he'd shown any kind of aggression. The time in the bathtub she hadn't really even been able to fight her, so he'd just taken her as she was. "Sebastian, no!" She wailed.

He rutted into her and took her clit in his one free hand, teasing it slightly. He was starting out slow, trying to get her to want him. "Tell me it doesn't feel good... Tell me you hate it and I'll stop."

But she couldn't she couldn't tell her brother that this didn't feel good. God she hated herself for it but the way he was touching her clit she couldn't help a scream of pleasure and frustration. "I'm waiting… If you want me to stop now is your chance…" But she couldn't tell him to stop. Jace had never made her feel like this, she moved her hands from where they were trying to wrestle Sebastian's hands off her throat to his hips, gently encouraging him to fuck her.

"I'll be damned," Sebastian said.

"Shut up!" Clary said shrilly. A filthy little moan worked it's way out of her lips and one hand went back to Sebastian's hand. She squeezed his hand, signaling him to hold her neck tighter. "Squeeze my neck, or I'm going to scream."

He squeezed her neck as she requested. He squeezed her neck for a good minute until she was red in the face and then let her breathe.

She was gasping, letting cool lungfuls of air fill her up as he rode her. "Fuck I hate you so much!" She screamed.

"How much do you hate me? Show me, baby," Sebastian purred in her ear.

She slapped him across the face sharply. "Only that much?" He said lightly. There was a brightness to his eyes she hadn't seen before.

She slapped him again and she scratched her nails down his neck, he let out a little purr of delight. "Now we're getting somewhere."

She wondered why violence made him horny. She wanted to be violent though, she wanted to take out her frustrations on him, take out every little thing about him that made her angry on him. He bit down hard on her neck, so hard he drew little droplets of blood. "Does that feel good little sister?"

"Fuck yeah, it does." She whined in his ear.

He bucks into her several more times. She can feel he's close can feel his strokes getting more and more ragged. "Harder Sebastian!" She screams at him.

He puts his hand back down on her throat and squeezes as he fucks her. One, two, three strokes later he's spilling into her.

Clary is so close to cumming that just feeling the warm pool of his seed filling her pussy up makes her cum.

She hadn't realized it but she'd passed out. She'd been so exhausted from their session of fighting and fucking that her post coital haze had led to a post coital nap.

The world swims into view as she begins waking up. Someone's body is pressed up next to her. "Sebastian?" She asks into the dark room.

"Mhmm. That's my name don't wear it out." He says sleepily.

"Sebastian! Want to explain to me what just happened?"

"I think you know the answer to that." He said, rubbing the sleep out of his eyes.

"Ugh!" She said shrilly.

"Hey," He said softly, rolling over so he could face her. He cupped her face in his hand. They both could use an iratze. "I love you, Clary."

"No, you d-"

"Don't tell me how I feel."

"You're my brother…" She said with a sigh.

"I'm your brother and I love you, and someday you're going to trust me."

She let out a long sigh. "I mean it," Sebastian said.
