He buried his nose in her red curls, taking in lungfuls of the scent that had plagued him the past week.

"I didn't mean those things I said- no, I did but I shouldn't have said them. Will you forgive me? Tell me you will," he said almost urgently, his mouth by her ear; she felt so good back in his arms, yielding and soft and curved, right where she should be. He didn't want to lose her, have her close herself to him.

"...Cant breathe...!" he let up and raised his head to look at her, his hands cupping her face. "Of course I forgive you." she breathed, arms locked around his neck and she closed her eyes briefly, caressing his palm with her cheek. Jonathan felt soothed as she glanced back up at him, her eyes now a murky green. He found his eyes drifting down to her parted lips, his dick twitching to life in his pants and his fingers moving to wind into her hair. His gaze flickered back up to hers, which was hooded now, before he leant in, eyes falling closed and his nose nudging against hers.

The minimal space between their mouths grew heated as their breath mingled together for a moment and then her mouth tentatively met his. He sighed as they broke away only to reconnect a second later; he sucked her top lip into his mouth and she swiped her tongue along his bottom lip, whimpering slightly and sending his blood south. His hands tightened in her hair as he pushed her lips apart and licked into her mouth, a noise vibrating in the back of his throat when her tongue slid against his. As their kiss became increasingly passionate, he wrapped his arms around her waist and roughly pulled her flush against him, his erection solid and straining against his constrictive jeans. His sister went up on tip-toes and dragged his bottom lip through her teeth provocatively, setting fire to his blood and fisting her hands in his white hair.

Jonathan couldn't take it anymore. He pinned her against one of the walls that lead out from the hallway door and pulled her dark green shirt up to bunch around her middle. He clawed down her underwear, his mouth remaining hot and feverish on hers, before he started on getting his jeans undone. Clary was gasping, tugging at his hair and returning the pressure of his mouth forcefully as if she was as desperate as he was. And he was more than desperate. He impatiently pushed down his jeans and boxers and hitched her legs up around his waist, holding back long enough to squeeze his hand between them and find her clitoris. She shuddered and started moaning as he massaged her firmly, moving his mouth to ravage her neck.

"-I need you inside-!" she half-begged through her moans and he didn't hesitate- right then, he had no willpower at all. He aligned his aching dick with her hole and met her wanton gaze before he rammed up into her. She instantly cried out, shivering and arching against him, clamping vice-like around his member. Jonathan swore and only managed three tight thrusts before he was groaning out her name heartily and unloading inside her. He rode out his orgasm hard and fast enough that he had his sister tensing around him again and mewling loudly, her nails biting into his shoulder and her fingers all but tearing at his roots.

His hips slowed to a stop as he revelled in the aftermath of his long overdue climax, feeling weakened by the intensity of it. They were both panting heavily and he leant his forehead on her shoulder, his hands still gripping her thighs. He could feel her heart pounding in her chest, matching the beat of his own and he focused on it as they gradually regained their breath.

"...Am I imagining all this?" he heard his sister question quietly, turning her face to touch her lips to his hair.

"Definitely not." he replied, his breathing still a little thin as he nuzzled her neck.

"You really came back," she whispered, her voice full of relief and gratitude as she hugged him closer to her.

"You know, its quite insulting how much you underestimate me," he remarked, far too clouded in bliss and contentment to sound even remotely insulted.

"Maybe you think too highly of me," she countered, her voice more serious now. Jonathan stifled a chuckle, kissing the edge of her jaw affectionately.

"By the way," he began, speaking lowly into her ear. "I hope you don't mind, but I'll be fucking you senseless for the next few days. I've gone without you enough for a lifetime." he felt a shudder go through her at his words and he smirked against her neck, finally pulling out of her and wrapping his arms around her tiny frame; she removed her legs from around his waist so that her feet were back on the floor and she looked up at him as if she still couldn't quite believe her eyes.

"I'm so glad you're back." she told him before holding him close and pressing her face into her chest.

That night, Jonathan lay in bed with Clary, the lights off and the house still, although charged with an undercurrent of energy. As if this moment in time, this reunion they were sharing was different- special- more meaningful than any other time they'd spent together. They lay on their sides facing one another, their faces inches apart and their hands clasped between them as if they both needed the constant skin-on-skin contact. Jonathan felt at peace within himself as he softly returned her gaze; his heartbeat was as rapid as it always was in his sisters presence as if she was a dangerous wildcat that could turn vicious any second, but there was a calming air radiating around them.

She leaned forward and bestowed a feather-light kiss to his lips as if checking he was real before going back to gazing at him tranquilly. His heart fluttered at the gesture and his lips curled into a small smile.

"I must love you," he murmured thoughtfully, belatedly realising what he'd just said and mentally chiding himself for his lapse of control. Clary's eyebrows shot up almost comically, before they drew together, something like concern darkening her features.

"Why must you love me...?" she asked quietly, gaze becoming observant as if trying to read the truth behind his words. He wasn't sure if he should be annoyed by her apparent doubt, although he could easily understand it.

"Because, my precious sister," he began, unclasping his hand from hers to cup her cheek and then glide it down her neck to her shoulder. "I think you are perfect. Every inch of you." he murmured, his hand running from her shoulder down her side and over the skin of her thigh, beneath her shirt, stopping on the back of her knee. She swallowed and gnawed on her lip, blushing profusely as he watched her.

"Every inch of my body?" she returned, mildly sarcastic but she seemed more embarrassed than anything else. He couldn't think why.

"Yes." he answered honestly, deliberately moving his hand to palm the swell of her left breast under her shirt and stroked his thumb teasingly over her nipple. "And every inch of your mind," he leaned in and pressed his lips to her temple. "Maybe its because you are human and I am not."

"Half human. And you were once," she reminded him, touching her fingers to the pulse in his neck; if she was surprised by the speed of it, she didn't show it.

"While I was still in our mothers womb," he allowed, his tone emotionless. "And then, only briefly."

"Our mother?" Clary repeated dumbly, visibly trying to ignore the effect his hand was having on her as it absently kneaded her breast.

"She is, is she not?" Jonathan said, quirking an eyebrow as amusement flickered in his black eyes. His sister rolled her eyes half-heartedly.

"I just don't think I've heard you call her that before," she told him with a delicate shrug, concentrating on tracing the flicks and arcs and lines of his rune-engraved chest.

"We all have to accept things we cant change in the end," he murmured softly before shifting nearer to his sister so that he could rest his forehead against hers. "I cant call you my sister unless I acknowledge that your mother gave birth to me. However much she hated me the moment she set eyes on me."

"She didn't hate you, she was scared," Clary protested predictably but there was no bite behind her words; she met his bottomless gaze timidly and he kissed her nose.

"Doesn't hate spring from fear?" he questioned, smirking a little as she rolled her eyes again.

"I thought we weren't going to talk about the past anymore?" she quipped irritably, frowning unhappily.

"You're right." Jonathan relented with a sigh and returned to simply gazing at her, drinking in all her features and expressions. If it wasn't for how much he enjoyed the sound of her voice, he would do nothing but stare at her all day- with intervals of mind-blowing sex of course. His sisters face growing haunted again caught his attention and he nipped her bottom lip so that she'd meet his gaze. "...Are they here now?"

"No..." she answered hesitantly, her eyes flitting about the room instinctively before they returned to his. "They wait until you're out of the room- like they're hiding from you so that you'll think I'm crazy," she confided in hushed tones, her gaze trained on his as if to make sure he was listening. Jonathan nodded slowly, studying the feral glint in her eyes as they flew quickly around the room.

"What are they like?" he asked after a pause, his tone patient as though he was a parent talking to his child. "Are they angry, happy, sad...?"

"I guess Mums a little sad...but she would be," Clary nodded, looking sheepish now, her voice still low.

"They don't...hurt you?" he prompted cautiously, fingers stroking her hipbone.

"No," she shook her head adamantly, holding his eyes unflinchingly. "I don't go near them. But..." she broke off, wincing slightly.

"But?" he pressed firmly, trying to recapture her gaze. She closed her eyes, bowing her head.

"When I...broke the bathroom mirror..." she let the rest of the sentence hang wordlessly in the air between them. Jonathan sensed his eyebrows pulling together as he processed what she was telling him. He felt another bout of guilt chew away at his insides for leaving her to her own- conclusively dangerous- devices. His eyes subconsciously ran up and down her body, visually examining the bare skin on show, for cuts or bruises or any other kind of damage. Not that the lack of visible wounds reassured him much about her current state of mind.

"Tell me about your nightmares," he ordered more than requested, although his tone wasn't particularly harsh.

"They're stupid really," Clary dismissed automatically, doing her best to smile at him; he levelled her with a look and she heaved a sigh in response. "Honestly, its not really what they are, its the having them every night- every time I fall asleep- its just...exhausting,"

"Why didn't you use a rune to knock yourself out?" Jonathan asked carefully, monitoring his sisters reaction intently. She blanched.

"What do you mean?" her forehead creased, momentarily side-tracked from the talk of nightmares. "There's no way you left a stele here..."

"I wasn't going to leave you entirely helpless. Not after the mirror," he said breezily as he leaned over her to rummage in the draw of the bedside table. "I thought you would have found it, considering your knack for prying into my things," the redhead had rolled onto her back and latched onto his neck with her tongue and teeth, when he retrieved the smooth cylinder from the draw and held it up for her to see vaguely through the darkness.

"You really left a stele here...?" Clary whispered almost bewildered as she looked back and forth between him and the object in question. "If I'd found that I could've escaped..." she continued, her tone partially reprimanding.

"I trust you." he replied, smiling in encouragement. "Anyway, you didn't look for it, let alone find it. So you mustn't have been in any physical danger," he gave her a look, wishing for confirmation of his assumption.

"Jonathan...I didn't look because I trust in your careful planning, not because I didn't need or want it," she admitted, pausing to see if he'd say anything before she went on, subdued. "For you to leave a stele here, was just plain reckless. Do you want me to leave?" he couldn't help the frown that had crept over his sharp features and he slowly replaced the stele in the draw.

"I don't understand," he began, moving back to lying on his side but now propped on his arm so that he could look down at her. "Are you telling me that if you'd found it, you would have left?"

"I'm telling you I don't know what I would've done." she said, looking less than pleased with herself before turning her gaze back up to him.

"Well, I meant what I said." Jonathan told her eventually, his tone sincere as he tucked her red curls behind her ear. "I trust you."

"Don't say that," his sister whispered, shaking her head a bit and looking acutely miserable. "I'm no more trustworthy than you." Jonathan chuckled at that, smirking mildly down at her.

"Of course not," he agreed, lying down properly and slipping his hand beneath her shirt again. She shivered, biting her lip. "But if anyone can truly trust us, its each other. Don't you think?" his hand had returned to fondling her breasts and blood had risen to her freckled cheeks.

"What makes us so special?" his sister asked rhetorically, looking away.

"I believe the bond we share to be unbreakable," he answered anyway, brushing his knuckles over her nipple. By now his dick was throbbing in his boxers, but he remained content with merely touching and looking for the time being. "And I don't mean our blood- though that too is an irreversible tie. No, I think we know each other rather well by this point and I can safely say I trust you with my life."

"How can you be so..." she didn't finish, clearly biting down on exasperation; Jonathan only smiled calmly and pressed his lips to her collarbone.

"Food for thought," he told her lightly, pushing aside her shirt collar and trailing kisses along her shoulder.

"As if I needed more stress," she complained, but her fingers were already weaving into his ivory locks, her thoughts derailing. A smile tugged at his lips as he moved them to the hollow beneath his sisters ear, his fingertips stroking her ribcage before he grabbed at her waist. His sisters hand sought his and lead it down into her underwear after a moment. Jonathan raised his head as she moved his fingers in circular motions against her clitoris.

"You're disgusting," he informed her adoringly, smiling crookedly down at her flushed face.

"So are you," she returned pointedly, a shameful expression colouring her features, even as she continued touching herself with his fingers, lust shining through.

"Oh, but you love it," Jonathan smirked, his dark gaze turning calculative. "You should feel how much you want me. Feel how wet you are," he withdrew his hand to catch hers and press her fingers against the sweet spot his had just been. Clary took in a shaky breath at his watchful, heated look and reddened further, closing her eyes and turning her face into the arm he was propping himself up with. He leaned down and nudged her cheek with his nose as he rubbed her fingers faster; keeping her eyes closed, she tilted her face up towards his and he brought his mouth down on hers. Desire ignited more fiercely in his veins as his sister moaned into his mouth, gasping and biting savagely at his top lip.

The white-blond watched in awe as his sister threw her head back against the pillows, her fiery hair splayed out around her, and cried out, her face flooding with relief and satisfaction. It took every fibre of his self-control to wait for her to recover herself and meet his gaze again, her own still hooded but a tad sleepy. His hand lay on her thigh now and she self-consciously wiped her fingers on her shirt, her free hand lifting to cup the nape of his neck.

"Didn't you say something earlier about 'fucking me senseless'?" she coaxed tentatively, expression full of chagrin as she looked up at him expectantly.

"I did," he began, his eyes momentarily inscrutable and his face almost placid. In truth, all he wanted to do right then was fuck her senseless but he found he needed something more, just as desperately. For a few seconds, he struggled for the right words, the right phrasing and it wasn't a little disconcerting. "I don't want to fuck you," he paused, recognising the white lie and his sisters look of disbelief. "That is, I would like to make love to you instead." he amended, gauging her inevitable surprise and discomfiture.

"Call it whatever you want," was her only response, her face fairly calm and her fingers stroking his neck. Jonathan studied her for a minute before he sat up, the cotton covers bunching around him and he started unbuttoning his sisters shirt, which actually belonged to him. Her chest was rising and falling quickly and his own breathing grew even thinner with anticipation. He wasn't exactly sure what the difference between making love to someone and simply having sex with them was- or even if there was one. However, he pushed that line of pondering aside as he relieved his sister of her shirt and carefully pulled off her knickers.

He shimmied out of his boxers and climbed into the space she'd created between her legs, lowering himself onto her and capturing her mouth with his. If he was crushing her with his weight, she didn't protest, merely reciprocated his advances, her foot rubbing up and down the back of his thigh and her hands clinging to his shoulders. His whole body was thrumming with the need to claim her and he tensed against it, focusing on the taste and texture of his sisters mouth.

"I don't know how to do this," he admitted after another moment, abruptly breaking their kiss.

"Jonathan, we've done this about a thousand times," Clary replied patiently, seeming to have forgotten to be repulsed by that fact.

"I know, but that was just sex," he hedged, frowning slightly and pursing his lips subconsciously.

"'Making love' is just an expression," she explained, tenderly brushing a white lock out of his face. "It just means the two people having sex love each other,"

"So we cant?" he asked, mildly petulant now as he stared down at her. "Because you don't love me."

"If you think you love me, then this will be you making love to me, right?" she countered, shifting awkwardly and avoiding eye-contact.

"It wont be the same." he stated, schooling away his expression, his eyes boring into her.

"Its really not that big a deal," she retorted, a scowl tainting her features now. "Either we have sex or we don't- its your choice since everything has to be your way." his heart stuttered in defiance at her clipped tone, but he refrained from snapping back at her.

"Then do it your way," he said finally, his voice edged and a taunting glint in his black eyes. Clary gave him a look.

"Fine, no sex," she proclaimed, raising her eyebrows. "That's what you want me to say, isn't it? You want me to argue, to force you to take me against my will."

"After all, that's how it should be with us. That's what comes naturally here," he agreed scathingly, even as his blood pumped with excitement.

"No. Its not." she said, deathly quiet as they glared at each other. "Because its never going to be against my will. Not now. You made sure of that." Jonathan just looked at her, his face unreadable and his body still wanting. His muscles loosened up fractionally and he smiled ruefully down at her, taking her aback.

"I'm going to make love to you," he promised softly, taking her face in his hands. "Any objections?"

"No." the redhead answered shortly, but she was already flushing again, her hands coming up to rest on his forearms. "There's seriously something wrong with you," she murmured but her tone was gentle, almost sad.

"Easily fixed." he smirked, grinding his rock hard dick against her once. Her lips parted and he took the opportunity to recapture them, kissing her long and lingering. His hands slid down to her thighs and he widened them a bit before guiding the head of his dick to her entrance and sinking deep inside her. She gasped audibly and he groaned into the back of her throat, his body quivering with the urge to pound into her. He held himself back, creating a full, slow yet firm rhythm, meeting her mouth over and over and smothering the noises she was making. He fisted his hands in the sheets, gradually moving his lips to the crook of her neck and closing his eyes.

"I hope you're enjoying this," he managed to say, his voice rough. "Because its really hard..."

"Don't tell me how hard it is- I'm on the receiving end," she gasped out, only partially dead-pan. Jonathan let out a laugh in gusts of pants, burying his face in her neck briefly. He lifted his head again to grin down at her and his lower half slightly picked up speed of its own accord. Clary moaned wantonly, her clammy hands grasping at the equally humid skin of his shoulders and her head going back. He licked up her throat and she leaned back up, searching for his lips. He released one of his hands from the bedsheets to shakily press against her cheek as she swirled her tongue around his, his hip-thrusts more or less on auto-pilot now as his mind wrapped itself in the action and sensation of his sisters mouth feeding off his.

It was only when she went rigid around him and tore away from his lips to scream out his name that his body and mind reconnected. Not a second later, his seed was exploding inside her and his entire frame was shuddering with his pent-up release. His back was arched and he was panting labouredly, his eyes drowsily falling shut. A satisfied grin twitched up the corners of his mouth as he slowly blinked his eyes open again, lowering them to the blissed-out girl under him.

His heart tugged as he collapsed on top of her, hugging her to him and nuzzling the side of her neck. If anything, he knew now without a doubt that he was never going to want to be inside anyone but Clary. He didn't know if that was a facet of love or just a result of his warped mind and twisted nature, but it was a change in him nonetheless.

Hey, sorry about the delay and sorry if the ends a bit rushed.

Hope you enjoyed!

Also, I feel like I should reiterate that this is a Clabastian fic. I'm not saying it will end with gumdrops and rainbows, but if/when Clary gets saved, that is where the fic will end. So no proper Clace will be happening here. Sorry for any disappointment, I just...dont write Clace. And thats all I have to say about it really. Any of you who'll now give up on this fic as a result, thanks for reading this far! :)
