Summary: Clary meets Magnus for the first time without getting her memory erased. What she finds though from meeting him would last her a lifetime and bring her happiness as her mother had kept her away from Magnus really for one main reason.

One-Shot

"Well, well. Look it here. I don't remember inviting any children of the Nephilim." Magnus walked out of the small room on his property where he had been sitting while the others were partying amongst themselves. Though he had been startled to smell her an feel her as well which was made him come out of his room for relaxing and ignoring the others around him. His dark gaze landed on her beautiful form standing there dressed there in a short black dress, leather boots with palm leather gloves and a short small leather jacket with her dark crimson hair falling around her shoulders and down her back.

"Magnus Bane, we need to talk." Jace spoke as he moved closer to Clary's still form as he did not like the dark look of desire flashing in the male's eyes as soon as he laid eyes on Clary's barely dressed form. He mentally cursed Isabelle for dressing her up like this an fought the itch to draw one of his blades to try and protect her.

"You guys know I don't like you," Magnus began with a slow drawl as he spared Jace a dark look of amusement as he sensed the male wanting to protect Clary from him making a seductive smirk curl upon his lips, "But I will let you all stay because of the hot beautiful one." He pointed out crossing his arms over his chest staring at Clary some and watched hungrily as she blushed some with being stared at.

"Thanks." Chorused Isabelle and Jace at the same time causing Clary to give them a soft snort amusement though she ducked her head some as Alec, Simone and Magnus gave her amused looks at her sense of humor.

Alec shook his head at the female cause truth be told he found her sense of humor funny in a way. He didn't mean to harsh towards; he just thought she could have a better life away from being a damn Shadowhunter.

"What? Not you two," Magnus pointed out with a dark look of amusement as both looked startled and upset at not being considered hot, "Her, little Red here with eyes of pure emeralds," He motioned with a wave of his hand towards a blushing shocked Clary, "Hello Clary." He nodded to the female as he shocked the others with his words.

"Wait! How do you know her name?!" Simone demanded with a dark look as he went to walk forward but blushed some as Alec grabbed his arm and forced him to stay put. He would never admit but he had been questioning his feelings ever since he had met the male before him.

"Come with me." Magnus wrapped his arm around her shoulders ignoring the Mundane male as he lead her away from the others and into the place he had been relaxing at. He shuddered as he felt heat and a shock of desire at touching her for the first time in two years.

Clary watched as the male poured himself a drink with a sigh slipping past his lips. She shuddered as his dark eyes landed on her though she was little ticked off at the male for messing with her mind and taking her memories as well.

"Where's your mother?" He asked of her as she stared at him with many emotions passing through her eyes at his questions. He knew she was probably ticked off for him messing with her mind with taking away her memories but he had no choice. For it not only hid her but also protected her as well till she came of age though it pained him each time to take away her memories away especially of himself.

"She missing." Clary bit out with a glare to the male fighting back the urge to release her tears as pain hit her chest at the thought of her mother being harmed in anyway.

"That explains it then. You mother never once missed an appointment with me; you were supposed to have been brought to me a couple of days ago to strengthen the spell. I have never in all my long years have created such a successful spell before yours. The symbol you have been drawing was a key that your mother was supposed to bring you back to me for me to redo the spell itself. But as the years passed by you started to become as some would same immune to it and needed the treatment more frequently then others would have," He began to explain softly to the female before as she looked at him with a hurt and acceptance making him see that maybe she was more mature now, "What you have to understand Clary is that your mother did all this to protect you from the Shadow World and from others as well. " He finished as he saw she was actually listening and taking everything he was saying in unlike some people as they would have started to play the victim here even though in reality she was the victim.

"Oh," Clary barely managed as she sucked in a deep breath feeling so many emotions swirling deep within her. She felt so many especially towards the Warlock before her, cause ever since he had touched her to guide her away from the others; she felt heat fill her entire body, "Thank you for the help by answering my questions." She finished softly and for once decided to be mature before she turned away from the male and went to leave.

Magnus moved fast stepping in front of her shocking her with his movement, "Just know this. It wasn't Downworlders you mother was running from it was the Shadowhunters." He spoke as he was fighting the urge to take her. Though he did act on impulse with pulling her form against his own and kissing

her hard on the mouth causing her to give a shocked gasp before he pulled back with his glowing the cat look, "When you feel it come to me." He whispered against her lips as she looked shocked at his words.

Clary moved walking out of the room.

"Simon's been taken by the vampires." Jace ran up to her with an alarmed look as she went from confused looking to looking pissed off in a matter of seconds.

Middle of the Day

Clay paced her room that was given at the Institute as Simon was resting in the Hospital Wing. She was thinking over and over about Magnus's words and wondered for the first time if maybe the male knew what she was feeling when he had touched her, was near and finally when he had kissed her on the mouth. She knew she should feel horrified in feeling something like this for someone she had just met but still it was there was something missing from her but when she was near Magnus...everything fell into place and everything felt right.

Growling low in her throat she moved not even bothering to change out of the dress Isabelle had loaned as she moved grabbing her jacket and slipping out the door. Moving fast as she could without waking the others up or even alerting them; she moved heading for the door to leave the Institute.

"Clary?" Alec's voice stopped her from moving as she internally cursed as she stopped turning to face with him mixed emotions on her face, "I was right then...in what you mean to Magnus." He whispered in shock as he had never heard of a Nephilim in being the mate of a Downworlder till now.

"What?" She frowned at him with different emotions playing on her face as she stepped towards the male with wanting answers from him.

"Look Clary, I know you have not been amongst us very long but you need to know everyone has a destined out there. And it would seem as if you are Magnus's destined one. If you go to him now, then he will claim you as his mate and no one would be able to take you from him. Having a destined and finding them is like finding the other half of yourself an being whole finally." He explained as her eyes widened in shock at his words.

"You mean to tell me, I feel right and whole with being around him cause...cause I his mate or something like that?" She managed out with a stunned look as he gained a soft amused as one would with their younger sibling doing something amusing and blushed some.

"Exactly. Think long and hard before you go to him." He nodded to the female but paused as she gained a sly look as a small smile played on her lips.

"That's why you barely let Simon out of your sight since you have met him." She grinned like a Cheshire cat or one that got the cream and bird at the same time as he blushed some at her words before scowling darkly at her, "Look, I have known Simon all my life. I can tell when he is crushing on someone and he is certainly crushing on you. Don't hurt him, explain everything to him like you just explained to me okay and he will have his mini freak out but accept it all the same. But you better hurry before Isabelle makes a move on him." She winked before turning and leaving the Institute and a blushing male behind.

Alec shook his head before her words registered in his mind and he growled low in his throat. Turning on his heel he stormed for the Hospital Wing. There was no way in hell he was going to allow his sister to even lay hands on his mate; he would raise hell before that happened.

Clary made it to Magnus's place and was nervous as she opened the door and entered the place. The court yard like area was clear of all Downworlders and looked normal as can be as well. She really had thought over everything Alec had informed of what would happen if she came to Magnus. But if there was one thing she knew and it was over the last couple of days was to follow her newly gained instincts. She knew that she should feel horrified and disgust in the way she was wanting for some male she had just met to claim but no that wasn't really the truth. She knew him all her life except she didn't remember cause her mother forced her to have her memories erased from her.

"Well, well, Little Red has returned." Mused Magnus as he walked out and stood there watching her as she whirled around to face with mixed emotions on her face. Though he saw someone must of explained everything to her especially on what she was to him, "You know what you mean to me then?" He questioned softening his tone towards her.

"That I am your destined...your mate?Yeah Alec clued me in on it as I was getting ready to leave though come to find out his mated to my best friend." She shrugged her shoulders as she stared deeply into his eyes as blushed some as desire was swimming in his gaze directed towards her.

"Funny, Shadowhunter and Mundane boy. I thought I sensed something between the two when they had been here," He spoke before he tilted his head as he walked towards and aloud a small smirk to curl over his lips as she stiffened and blushed some, "Why are you here then? You should be running away? Did you know what would happen as soon as you came back here to me?" He questioned as moved trailing his fingers over her cheek.

"I have mixed feelings but being here and with you feels right. It feels as if I am suppose to be here with you, near you and to never leave your side." She breathed out as it felt as if her body was heating up from the inside out as he touched her an circled her to where his lips were now next to her.

"And would you let me, let me claim you as my own that is. Like you are destined to be. If you are not ready to be claimed as my mate then I suggest you leave now and run with not returning till you are ready to be mine. Cause I promise this you this; if and when I do claim you, I will never ever let you go nor will I allow anyone else to have you or harm you." He promised darkly and seductively in her ear making her shiver as he moved his hand to where it slowly in circled her waist bringing her closer to his body as he fought the urge to groan as warm body was pressed against his own with the scent of arousal hitting him as well.

"All I have been doing lately is running away from everything either from demons wanting me dead or something to do with that blasted cup or for my life. Hell I have been unknowingly running my entire life with my mother. For once I would rather run to something then away from something. I know I should be running away and denying this whole thing but for some reason it feels right...it feels as if I have finally found my way home and I feel safe here with you like nothing could ever harm me while I am with you." She breathed and shuddered as she felt his breath on her neck as he moved her hair aside and shivered in pleasure as his lips barely scraped over her shoulder.

"Your instincts guide you along with everything," He began as he brushed his lips once again against her neck and smirked as she shivered, "One last chance to run cause I meant it once I have you. I will never let you go." He growled against her as she moaned softly as he held her in place.

"Then have me. Cause I am tired of running." She breathed out with breathless tone as she felt as if she was burning up from the inside out with need swimming in her veins for the male behind her holding her to his body. Closing her eyes she leaned back against the male and tilted her head to the side before whimpers and small moans escaped her as he attacked her neck harshly without mercy.

Magnus growled in approval as she whimpered in pleasure in his hold before he used his powers and moved them fast to be inside of his bedroom. He locked up the entire place with his powers as he moved turning her around and crushing his mouth onto her as her hands buried themselves into his hair pulling him even closer to herself. He grabbed her thighs in his hands lifting her up before turning and sitting on his bed with her straddling his lap causing her to gasp as he used his magic with melting away her clothing.

Clary jerked back some as she turned bright red to straddling his lap with wearing nothing but her birthday suite and turned ever redder as she felt and saw he was just as naked as herself though she ended up tossing her head back in pleasure with moan as he buried his hand in between her legs stroking her slowly and sensually casing her to grip his shoulders with her hands and nails.

He smirked as he watched as her eyes closed in pleasure as he stroked her before making her whimper and gasp with rocking gently back and forth as he slipped a finger deep within her causing her more pleasure. He felt his eyes shift to their glowing cat form as he felt how wet she was and as she whispered his name like a small prayer. He could feel his instincts from his demon side rise to the surface in wanting to finally slide into her and claim after years of waiting for her mature and reach of age to become his.

"Clarissa, I take you you are mine for good. There is no take backs or escaping." He wrapped his hand into her hair and pulled her down to look into his eyes though he was shocked as she reached down removing his hand before she slowly slid herself down his cock wincing in pain as she broke through her barrier with a whimper.

"Good cause I don't want to be let go of." She breathed out in pain and tried to stay completely still on top of him though relief filled her as he stroked his fingers across her stomach and hips as she found the pain disappearing and blushed some, "I...I don't know what to do." She muttered turning her head away with her cheeks turning bright red.

Reaching upwards, he grabbed her chin and forced her to face him, "I'll teach." He murmured as he pulled her down so he could kiss her lips. Shifting some he grabbed her hips and helped her rock back and forth as he thrust upwards deeply into her delighting in her moans of pleasure slipping past her lips.

She gripped his shoulders as she rocked faster and harder to gain friction and more pleasure. Though she gasped as she suddenly found herself being pinned to the bed as Magnus growled with his glowing period as he shifted and slammed into her hard, fast and rough over and over again causing her to cry out as she held out onto him tossing her head.

He couldn't help himself as he snapped and took his mate fast and hard. He found pleasure in her cries of delight an pleasure were coming from her as she thrust her hips upwards to meet his own thrust bringing them both pleasure beyond anything they had ever felt. A hiss left him as her nails clawed down his back no doubt leaving marks in their wake. Moving one his hands he buried it into her hair and pulled to where she was baring her throat to him causing her to whimper submissively and for him to growl as he made a jerk of his hips causing her to cry out in pleasure as both were nearing their release.

Clary screamed in pleasure and pain as she released and because of him biting into her neck hard before she felt him jerk back as magic and power encircled them both powerfully. Magnus felt the change and shift in them both as he felt his demon side rise to the surface roaring in triumph as he released deep within her.

Two Days Later

"Where the bloody hell have you been? Do you know how much Jace and Hodge have been worrying over you?!" Isabelle demanded as Clary walked out of the elevator though she was startle to see Magnus Bane with the female. She had been in a sour mood ever since her brother had nearly stabbed her for flirting with his newly found mate, Simon; who she had been crushing on.

"Watch it little Shadowhunter." snapped Magnus with a glow cat eyed glare to her with him following behind Clary closely ignoring as the female flinched in shock as both were heading for the others.

Clary entered the room and smiled as she saw Simon standing there close to Alec. A pissed looking Jace stood off the side as Hodge was sitting in a chair as well, "Hey." She spoke softly causing them all to look at her and Magnus in shock.

"Finally decided to stop running?" Alec smirked tauntingly at the female as she looked at him before looking at Simon some with an amused look as they both ignored Jace's glare.

"Yes, I see you finally decided to man up and stop being afraid." She taunted right back with devilish smirk upon her face as they were shocking the entire room.

"What the bloody hell?!" Jace demanded with a frown as he saw the way they were acting with one another and it annoyed him to hell and back to see Magnus Bane so close to standing beside Clary.

"I see," Hodge spoke with fear flashing in his eyes, "Simon and Alec are mates with Clary and Magnus being mates as well. Such a rarity to find." He answered as Isabelle gaped in shock and Jace looked hostile to them all.

"Like hell!" Jace jumped to his feet but stopped as Clary stepped forward.

"Simon and Alec are mates Jace. And some am I and Magnus with nothing or anyone going to tear us apart. No where have some work to do." Clary snapped back as her eyes took on a glowing green cat eyed look as Magnus stepped forward wrapping his arms around her tightly.

"She is mine forever." Magnus spoke coldly as Jace growled at them and stormed away from them all as Isabelle was just in shock of them all as well.

Elsewhere

In the dark and cold room a pair of bloodred cat eyes snapped open as they felt the shift in power. A small dark amused chuckle filled the chilly air as it vibrated the room as the figure stood from their bed. The demon had felt peace fill his only child and heir at last with meaning only one thing. His child had found and claimed his mate as his own. The Greater demon tilted his head before making the decision of finally paying his Heir a visit and to make sure no one would even dare to take away his son's happiness by harming his son's mate.
