All rights except plot belong to the amazing Cassandra Clare. I own nothing save the plot. Okay so I guess I need to warn about the

-Sex (there will be alot)- Non-Con

-Incest (You know being a Clary-Jonathan fic)

-Manipulation (Jonathan being Jonathan)

-Some mildly disturbing concepts

-Amorality (Again Jonathan being Jonathan and forcing Clary to do things against her will)

-The whole captive situation (Jonathan coming after Clary, taking her, that is what captive is and I would expect you people to know that there was a very high chance that this story had some because this is set after CoLS)

-This story is not for the goody two shoes of the fangirl world. This fic enters the more in depth, intense sub section of literature.

-Reader discretion is HIGHLY advised

-I only put these warnings up becasue I got scolded for 'not warning' the viewers for this kind of thing and I'm sorry about that, I know I should have put up a warning. Anyway here it is.

YOU'VE ALL BEEN WARNED! ;)

Walking down the New York street, the brisk wind did nothing to settle the cold feeling of being watched. The dawn light filtering in through the leafless trees colors the fallen leaves in a cold yellow and fights with the red for attention. It's been two months since the Seventh Sacred Site and Jace wasn't any closer to healthiness. She was beginning to despair that the Silent Brothers would ever find a cure. Clary has gone for a short walk to clear her head of the loneliness she has felt for the past two months, the withdrawal from Jace's touch. The Clave was being absolutely no help; all they were doing were sitting around discussing how they would find her brother and not actually doing anything. A cold chill rushes down her neck; though the park is empty she turns around to check for people. Upon seeing nothing but the leaves blowing in the wind she turns around only to run, face first, into a hard, muscled chest.

She throws up her hands to steady herself, backing away from the person she ran into. She could have sworn there was no one in front of her. "Oh, sorry. I didn't…" she lets the words drop from her lips as she sees the all too familiar devil smile spread across his face.

That smile shoves a cold knife of fear through her heart as she spins around on her heel, intending to bolt back to the Institute. She hears a low chuckle as Sebastian's strong arms wrap around her waist and pins her arms to her body. He pulls her flush with his body and breathes down her neck. Did he just smell her hair? She starts to kick frantically and opens her mouth to scream. Before she can Sebastian places a hand over her mouth.

"Nothing to be sorry about, little sister," he ducks his head down to whisper in her ear. "I told you there isn't a place on this earth where you could hide where I wouldn't find you."

Sebastian takes his hand off her mouth, "Now don't scream, sweet sister." He reaches down and pulls out a length of rope from his leather biker jacket. It has an orange hue emanating from it.

"Let go of me Sebastian!" she spits. She looks down at the glowing rope, fear tightening in her stomach. "What? No stele? Trying to go for the common kidnapper?" She snaps, trying not to break down in utter terror.

"Not exactly." As soon as the orange rope touches her skin she lets out a scream of pain. He swiftly ties them behind her back, pulling painfully on her shoulders. Sebastian takes this opportunity to gag her, tying a thick piece of fabric over her mouth, just under her nose. The rope shoots fire up her arms, diminishing just before her shoulders. He swings her up onto his shoulder and Clary lets out another muffled cry of pain. "But I still enjoy the challenge of old school."

The fire stabbing up her arms burns like hell but she still manages to thrust her legs out, trying to knee Sebastian in the face. Sebastian grunts as his head is flung sideways when Clary's knee connects with his jaw. He stops and brings a hand to his lip. It comes away black.

He chuckles and says, "Nice try little sister, but it takes a lot more than a bloody lip to stop me." Sebastian shifts his arm down to rest on her calves. This throws her off balance, sending her further down Sebastian's back. She fists her hands in his shirt and lets out a muffled shout of surprise. Then she growls and slams her fists into his back.

"Still the spitfire I see. We'll put that to the test later," Sebastian says with a hint of tantalization.

Clary freezes as she realizes the disgusting thing Sebastian just hinted at. Before she can react to this Sebastian throws her onto the backbench of a Jeep and slides in next to her. She wonders why Sebastian didn't take the driver's seat when she sees a head of white blond hair, identical to his son's, watching her through the rear view mirror with a devil's smile on his face.

"Welcome back, Clarissa," Valentine says coolly.

Clary, horrified at her nightmare made flesh, screams as loud as she can through her gag, using her legs she pushes herself up, trying to get away but only succeeds in pressing herself up against her brother who drapes his arm across the back of her seat. She screams until her throat is raw and her spine digs into her brother's side and she's having trouble getting enough air through her nose.

"Done?" Sebastian asks irritably. Valentine starts up the car, he drives down the street as if on a normal Sunday joyride, like he doesn't have his daughter tied up in the back. The streets of New York flash by as Valentine speeds down the street. Her eyes are still wide with terror, trying to process her father's existence, still paralyzed with fear and all too aware of her brother's lazy presence.

Clary whips her head around to glare at her brother with a deep hatred. Sebastian tilts his head to the side with a cruel smile, "Oh right, that."

He removes the gag and Clary practically spits in his face, "Take me back and go burn in hell."

"In that order?" Sebastian asks playfully, wrapping his arm around her shoulder and drawing her closer, grinning down at her.

"Yes, you ass-hole, in that order!" She thrashes out of his grip, dragging herself across the bench.

"Ouch," he holds a hand to his heart. "No need to be mean Clarissa. We're just having some fun," he says with a hurt look on his face.

"This isn't fun Sebastian! You can't go around kidnapping people off the streets!" She screams, hoping desperately some one on the sidewalks will hear her but looking out the windows she sees the streets abandoned, dawn light still hanging in the air.

"I can if that person belongs to me. You belong to me, I am only taking what is mine," Sebastian says coolly, his black eyes glinting with malice and anger, a deadly avarice flashing under the black violence.

"I am not yours, nor anyone else's!" Clary yells. She's slid back along the bench, leaving enough space for her to stretch out her legs between her and Sebastian but instead she brings up a booted foot and slams the toe of it into Jonathan's jaw. Sebastian's head only jerks to the side and his mouth hangs open in shock. He slowly brings his hand to his face, touching it gingerly and laughs darkly, short and bemused. The trail of black blood running down from his split lip drips onto his shirt and he wipes it away before turning on her with blazing black eyes.

She can't see anything in his eyes except for a dark glee and a cruel smirks twists his lips. Clary presses herself against the side of the truck, trying to shrink away from her brother but he just reaches across the space and grips her arm tightly, dragging her back across the bench. His vise like grip stays locked around her arm as he uses another hand to brush a stray curl behind her ear.

"Sweet sister," he purrs and Clary cringes, it would have been better if he had yelled but no he leans down so his breath blows against her cheek. "What am I going to do with you?" His voice barely a whisper and his closeness makes her skin crawl. She tries to wrench away but Sebastian holds her fast, chuckling.

He places a kiss on her cheek, lingering for far longer than a brother should. He pulls back ever so slightly, drawing her body closer to his, his grin never faltering as she squirms and before she can get free Sebastian whispers, "Sweet dreams, little sister," and presses his lips to hers. She recoils in revulsion as she tastes something tangy and everything fades to black.

Clary wakes up disoriented. She cracks open her emerald eyes and looks around the dark room. "This can't be happening," Clary says as she rolls over on the bed she was laid down on… and rolls right into her brother lying on the edge of the bed. She jumps back, muffling a scream with her hand. Sebastian is sleeping on the side of the bed next to Clary with an arm bent around the back of his head and his chest rises slowly in the soft pattern of sleep.

Clary looks down at herself to make sure all her clothes were still in place remembering what he had mentioned earlier. Finding that every article is still in place she gets up off the bed and blindly tries to navigate the room. It's damp and dark and the room feels large. Running her hands along the wall, after banging her hip on a dresser she finds a doorknob. Turning it slowly, she winces as it squeaks and the air behind her shifts as hot breath blows down her neck.

"And where do you think you're going," Sebastian asks snaking an arm around her waist.

"Anywhere but here," she says shaking off his arm, ripping open the door and bolting down the dimly lit hallway outside. There are only two more doors in the hallway and a glass window at the end. Before she can get out of the hallway she is slammed up against the wall and Sebastian uses the rest of his body to pin her to the wall.

"Do you really not like me that much, Clarissa?" Sebastian asks bringing his face down, looking directly into her eyes.

"Oh no," she says rolling her eyes, "I don't not like you, Sebastian. I hate you! I never said anything about it or wanting to come with you or interacting with you ever again!" She yells in his face. She struggles against the weight of Sebastian's thighs pressing her legs up against the hard plaster. Sebastian just scowls while Clary continues yelling at him, "Why do you even want me? I'm not special, I'm not even a Shadowhunter. I was brought up in the mundane world, I don't have years of experience with hunting demons and I've only just now learned about my rune ability! So why do you want me?"

Sebastian lets out an exasperated sigh, "Because you are a Morgenstern, Clarissa. You have Morgenstern blood just as much as angel blood. Father and I are putting both of them to use. Father and I want you to strengthen the Morgenstern line with me, to mix the blood of his two greatest accomplishments. Not to mention teh endless advantages your angel blood has to offer."

Clary closes her eyes and turns away in disgust, disgust that her own family would use her like this. She doesn't want to be here. She doesn't know if Jace is even aware she's gone or is even looking for her, if he would find her. Her father or brother separate she could deal with, but together? Sebastian forcing himself on her with the help of their father, no one to help her.

"Look at me Clarissa," Sebastian growls. He runs a hand down her neck, fingernails lightly scratching her skin.

Clary squeezes her eyes shut harder, trying to choke down the sobs building in the back of her throat. She's not going to survive this wit everything intact, she knows this but is unsure if she can get out at all. If it was just her brother or father separately she could give away their position or escape with some luck, she's done it before. It terrifies her what her family, her own family, would, will, do to her. Sebastian is going to get his way, she knows she can't stop him but she can give him hell along the way. Some small part of her hopes that Sebastian lied, that her their father doesn't approve of the purifying the bloodline, that Sebastian just said that to force her mind into believing there is nothing holding him back.

Sebastian growls angrily. "Then I'll make you." He brings his lips down hard on hers, pressing her harder into the wall. His mouth moves slowly on hers, trying to tease her lips open with his tongue, pleading for entrance. Clary keeps her mouth closed, trying to push him away but he stays cemented against her. He brings his hand up and touches a pressure point on her jaw, causing it to open but Clary snaps her mouth shut and rips her face away.

"What the hell Sebastian! Isn't Valentine around? Wouldn't daddy dearest be disappointed to find his perfect son locking lips with his daughter?" Clary says, desperately hoping her suspicion is right.

"Oh no," Sebastian shakes his head, a malicious grin plastered on his face, "He wants this. He wants his children to make the bloodline something so powerful no one can stop us. Our bloodline ties us together and yet that blood keeps us apart. I need you bound to me in every way possible because even if you do not see it you and I are the most powerful beings on this planet. And I will bind you to me, make you bend to my will, even if I have to tie you to the bed. You will eventually give in, become mine and I'm not a patient man." Sebastian grins like the devil incarnate and wraps an arm around her waist.

Clary kicks and screams, realizing what Sebastian means to do to her, "NO, NO, YOU CAN'T MAKE ME! I WON'T!"

Sebastian turns her around so she is kicking nothing but air as he walks down the hall. She screams and screams, sobbing all the while, letting hot tears flow down her face. She kicks at the walls trying to throw Sebastian off balance. "NO, PLEASE!" Clary is trembling against her brother. She knew this would happen but didn't expect it so soon and the thought even now terrifies her completely. "SEBASTIAN, I'M BEGGING YOU PLEASE DON'T!"

"Hush now. There's no need to beg now, I'll have you on your knees soon enough, then you can beg," he purrs, using his back to open a thick black door.

The bedroom is large but dark with a few solitary candles burning in the corner. The bed itself is huge, swathed in black silk and piled with pillows of varying sizes. A window on the far wall looks out on a dark beach, the waves lapping at the shore. The moon reflects like a silver disk on the still water's surface.

Still screaming, Clary is thrown down on the bed and Sebastian climbs on top of her. Clary moves to throw a punch but Sebastian catches her wrists and ties them at the head of the bed with a length of rope.

Sobbing, Clary calls out, "Jace! Jace!" Her screams are cut short as Sebastian presses the burning tip of a stele down on her neck and a rune of quietude sinks deep into her skin. He sketches another rune just below her collarbone, unfamiliar to her, but does nothing to change anything so she continues her struggles.

"I don't need you screaming that angel boy's name. It'll ruin my mood." He says, scowling.

Clary glares and brings her knee up, aiming for the place she knows will hurt most but Sebastian catches her leg and rips off her boots and socks. He gently kisses her ankles, slowly pushing up up her jeans and kissing her legs.

As soon as Sebastian's lips pressed against her skin she feels the unfamiliar rune flare up and send waves of unwanted pleasure coursing through her body. She gasps silently and arches her body off the bed. The unwanted sensation weakens her immensely as Sebastian enjoys his new plaything by trailing a hand up to her jean button and works them down her legs, throwing them across the room to expose black and red lace panties.

His eyes rake down her legs to her toes and up again to her face. "Angel, little sister you're beautiful… and all mine." He leans down to trail kisses up her inner thigh, slowly making his way towards her core.

This isn't right. She doesn't want this or her brother but the rune is forcing her to enjoy it, to make her melt in the palm of Sebastian's hand. It feels phenomenal, the rune. She arches her back as Sebastian reaches her core but falls back on the bed as he passes it and continues his work up to her stomach, pushing up her navy camisole. Sebastian apparently took her jacket.

He traces kisses along Clary's stomach up to her bra where he rips open the cami so it hangs to her sides, exposing her matching lace bra. Finally he presses his mouth to hers and this time she doesn't fight back despite how badly she wants to. The rune is making her lustful, craving Sebastian's touch as though her life hung in the balance.

She welcomes his kiss, trying to pull her hands down to wrap around his neck but they catch on the rope still securing her to the bed. Sebastian's hand comes up to cup her face while he ravishes her mouth. His other hand has different ideas. He drags it up her thigh to her core and runs a finger over the thin cotton separating him from her. She involuntarily arches into him, lusting for release.

Sebastian moves to her neck, gently kissing her pulse point. "Now that you're more compliant," he smiles against her skin. "I'm going to remove your rune of quietude, I wouldn't want to deny myself the pleasure of hearing you scream my name and I might as well let your hands wander."

His face still buried in her neck he reaches up and tugs in the rope which immediately falls away. Clary's hands fly to the back of Sebastian's neck and lace through his white blond locks. Next he draws back slightly to draw a slash through the quietude rune on her neck with his stele.

"If you're really going to do this, I feel slightly under dressed." Clary's shocked at her words, seemingly coming out of nowhere, she certainly hadn't meant to say them.

Sebastian grins down at her. "I can fix that." He leans back on his knees and pulls his black shirt over his head and tosses it across the room then kicks off his boots and socks. He dives back in to envelop Clary's mouth with his own.

His hand down at Clary's core pushes past the cotton and touches her. This sends another round of even more powerful waves of pleasure through her as a coil starts tightening in her stomach. He moves his finger around, pressing her in all the right places, eliciting multiple moans from Clary who tries to struggle against the intoxicating rune and Sebastian's touch but both are too powerful to resist.

His other hand runs greedily up and down her side, trailing sparks. Sebastian moves down her neck and sucks on the sensitive skin.

Clary has had enough but the rune won't allow her to move in any way except in rhythm with Sebastian's hand. He presses himself and his want against her, leaving her no where to go. After much struggling, trying to voice words, Clary finally gets out, "Sebastian…" She's disgusted with herself because it came out wanton and breathy.

"Hmm," he mumbles from his place at her neck.

"Sebastian… you need to stop… mmm… please. I don't want this."

"You sure, sweet sister?" In response he finds her spot and rubs it methodically, harshly, provoking a scream of pleasure to rip from her body. His hand moving down her hip shifts to his belt buckle and he slowly unclips it as he moves his mouth to hers and gently kisses her.

Clary hears the belt drop to the floor but before Sebastian can get the button open she hears a terse, "Jonathon!"
