Thank you all for the wonderful words of inspiration and I think I got everything figured out now. Some of you may not like this, some of you may love this but it is the way it needed to be for the ending I want. Sorry the chapter is a little short, my daughter has been sick with strep throat and not I am also sick. Also cross your fingers that I close on the house this week and then I will be able to post more often! This gets lemony so this is your one and only warning.

Chapter 14

It had been a week since Jace first came with Clary to the new house. They had spent that time tip-toeing around Sebastian, well; he mostly stayed in his own room only emerging when he needed food. The house was much smaller than the other one and didn't even have a training room so after several days of complaining Jace was ready to stretch his legs and check for any news from Brandon.

"I'm just going to be gone for a little bit." Jace said pulling on his leather jacket.

"But what if the Clave is out there looking for you and you get taken by them and I'm just sitting here waiting for you to get back?" Clary said sitting on the bed.

"Relax Clary, I can fight you know, and as long as I don't get too far away from the house I can "zap" back in here in a second, you know that. These houses were built for people on the run. I mean look how long Valentine was able to hide out safely, and I am sure that he needed to go out and get food a few times a week." Jace said; they had already had this conversation in various forms a few times already.

"I still don't like you leaving." Clary said giving up on the argument.

"I know baby." Jace said bending down to give her a swift kiss on the lips before he left.

Clary just sat on the end of the bed, her hands in her lap twisting and wringing. She felt "off" though she was not sure exactly what was causing the feeling. With a final huff she decided to go out to the kitchen and get something to snack on until Jace returned. He had promised to bring her back Taki's, which was a local diner she had so dearly missed.

She pushed herself off of the bed and headed out the door barefoot and in a comfortable pair of sweatpants and a tank top. She was startled as she walked out the door and ran straight into Sebastian.

"Sorry." Clary said quickly looking away.

"Clary." Sebastian said simply.

Clary looked up and met Sebastian's gaze, they had not been alone in the house since Jace had arrived, and he had barely spoken a word to her in the past week. There were many emotions reflecting through his eyes, from pain to anger.

Sebastian moved so quickly it startled a small scream from Clary as she was being pushed roughly against the wall behind her. She felt the sting in her shoulder where it had hit against the edge of the door frame. Sebastian was standing before her breathing heavy, but before she could even protest his lips crashed into hers. He was taking more than he was giving as his body pressed her further against the wall, she struggled for air but found she was kissing him back with a feverish passion.

Sebastian ended the kiss abruptly, removing his hands from her shoulders and placing them on the wall effectively trapping her but easing up enough to make breathing easier. Clary could hear a sort of low growl emanating from his throat as he looked at her with a tortured expression. Clary watched as he closed his eyes and leaned his head against the wall above her.

"I don't like fighting with you." He said softly.

Clary wrapped her arms around his torso to comfort him. "I don't like fighting with you either." She said into his shirt. She could hear his heart beating quickly under the thin fabric.

Sebastian retracted his head from the wall but kept his hands flat against the surface keeping Clary caged. Clary looked up to Sebastian as he looked down to her. "I was so upset that you just ran off to go and get Jace without me, we should have waited a few days before we went to get him, the Clave would be less suspicious that way." Sebastian said but Clary could tell he was not saying everything.

"I needed Jace here." Clary said determined not to back down.

"And what, you don't need me?" Sebastian said with a slight fire behind his words.

"Of course I need you." Clary said softly tring desperately to reassure him.

"Hasn't felt like it." Sebastian snapped.

"What's that supposed to mean?" Clary spit back.

With lightening speed Sebastian's right hand left the wall, trailing over her tight stomach and down under the waistband of both her sweatpants and underwear. "You're supposed to be mine." He growled as his fingers attacked her; the mark above her heart pulsating in time with her rapidly beating heart.

The Clary trapped inside her head watched with horror unable to move, unable to protest. She could feel his hands on her and she wanted to push him off, to scream at the top of her lungs but she was stuck watching from the inside as the demon that had taken over her body moved and spoke for her as it had for over a week now. All this time she has been stuck inside her own mind, the only place she couldn't be pushed out of, forced to watch and listen as her body acted on its own and said things she would never have said. She had watched helplessly as it had sex with Jace and she had screamed for him to notice it wasn't her, but he had not heard her and he had not noticed.

"I am yours." Clary heard her body say in a breathless moan like she was some sort of whore. Her body was craving his touch, but the Clary on the inside wanted to throw up.

"Then why do I hear you fucking him every night instead of me?" Sebastian growled, never relenting on his assault with his fingers. Clary squirmed beneath his touch and leaned back on the wall to let it support more of her weight.

"I need both of you." Clary whimpered closing her eyes.

"Well I need more of you than I'm getting." Sebastian said moving his left hand to cup her breast, there was no bra beneath her think tank top and he played roughly with her nipples through the thin fabric. Clary only groaned in response.

The real Sebastian was stuck inside his own head and had been for months now. The sight of what his body was doing and saying repulsed him worse than anything he had ever seen before. It was touching Clary; it had plans to do things to Clary that made him both sick and enraged. He had tried several times to regain control of his body, even if it had only been long enough for him to drive a dagger through his heart. The thing that was in control would not stop until Clary carried and delivered his child and Sebastian fought to never let that happen but had not even remotely succeeded. He had hoped Jace would have figured out how wrong things were by now, that if he could not regain control that Jace would kill him instead. Sebastian wished he had died in that house with his father.

Sebastian withdrew his hand slowly and Clary pouted at the loss. His hand was slick and he licked it clean slowly as Clary watched with hooded eyes. Sebastian gave her a sly smirk before picking her up, her legs wrapping tightly around his waist as he carried her into his room, shutting the door behind him with his foot.

Sebastian's lips were on hers as he carried her all the way to the bed and laid her down with him still firmly between her legs. He removed her shirt quickly, throwing it across the room, before sitting up to pull of his own shirt by the collar. It quickly joined the floor next to her discarded shirt. His hands traveled back up her body to resume the work on her breasts as he had been doing in the hallway.

Jace inhaled deeply as he left the house and his chest filled with the cool air of a New York winter. There was snow all over the ground and Jace shivered despite himself. He walked briskly with his hands in his pockets. The Clave was not here to arrest him, but he had not really expected them to be anyways. He could have returned to the old apartment by now but he was enjoying the fresh air despite the chill. He sent off a quick message to Brandon and then began to jog. He had felt so pent up for the past week and it had been more than just the inability to train. He was back with Clary and while that should have provided him with relief, something had been wrong though he could not put his finger on it.

He needed some time away to clear his head and work out his muscles in some way other than on Clary. She had wanted sex every day, multiple times a day in-fact. Jace was never the one to complain about an abundance of sex, but he had never seen Clary like this before. Maybe it was because she was trapped in the house and no training room to exhaust her.

Jace felt the welcome sting as his muscles in his legs started to burn, and he pushed through into a sprint relishing the pain. His breaths came out in white puffs as he ran, no longer feeling the cold as it hit his skin. His mind was slowly beginning to empty out as he enjoyed the high of exercising. All too soon he stopped dead in his tracks as he saw the slight fiery shimmer in front of him, it could only be a message from Brandon. Jace snatched the message out of the air and read it quickly.

The Clave does not know you have gone. No luck on clearing Clary. Spend more time outside in New York, let Shadowhunters see you are still there and alone. - B

The message burnt to nothing as Jace finished the note. He was breathing heavy, only now realizing how hard he had pushed his body in frustration. He would have to go to the Institute and let Maryse and Robert see him, maybe make up some lie about being held up in the house for the past week worried sick about Clary. That was the only place he could think that would mean Shadowhunters were guaranteed to see him. Jae shoved his hands back into his pockets and started the trek toward the place he had lived for so many years when he was a teen.

"Jace!" Izzy yelled as he walked through the large doors to the Institute. She crashed into him at full speed giving him a huge hug. She pulled away from him just as suddenly as she had been on him. "You have had me worried sick, first you demand everyone to come to Idris, then you kick us all out and not a word for an entire week." She said with her arms folded tightly across her chest.

Jace rubbed the back of his neck trying to decide if he should tell her that he has been with Clary or not. He only had a second to decide and picked to wait for now before telling anyone. "Well I didn't exactly take the news very well; I needed some time to myself." He said coyly.

Jace looked Izzy up and down, really noticing what she was wearing, and pieced together with the fact that she had been right by the front door when he arrived meant she was on her way out somewhere. Jace figured it was best to change the subject before he needed to explain anymore. "Where are you off to looking like that?" He said gesturing up and down her.

"Oh." Izzy squeaked as if suddenly embarrassed, Izzy never seemed embarrassed before. "I was just about to go to Simon's gig tonight." She said quickly.

"Simon as in vampire best friend to Clary?" Jace asked unable to keep his jaw from opening wide with shock.

"Yes that Simon." Izzy snapped defensively.

"Wow Iz. I didn't really think he was your type." Jace said feeling incredibly uncomfortable now that he knew he would have to tell Clary.

"Well I need someone to pass the time with now that Alec is always off with Magnus, mom and dad have been in Idris for the past few days, and you have been holed up in a disappearing house sulking."

"I was not sulking." Jace said quickly feeling the stab of disappointment Maryse and Robert were not there to see he was not with Clary. "I guess I won't keep you from your show, I just wanted to get out of the house and get some food from Taki's. I thought maybe you and Alec wanted to join me but I see you have other plans." Jae said wanting to get back to Clary as soon as possible now that he found everyone had moved on without him without so much as a blink of the eye.

"We could have dinner tomorrow." Izzy said a bit softer remembering his ego and how easily it could be damaged by the right kind of person.

"Sounds good." Jace said forcing a small smile.
