Summary: Being head of the institute is a stressful job sometimes. Lucky for Clary Jace is always happy to help her relax...

Clary Fairchild loved being head of the institute, at least that what she told herself every day to detract from the mountains of paperwork that made her question every day why she had wanted the job in the first place. Sure it gave her the power to change things, but it also meant less time to herself and much more time away from Jace. It seamed as if she was constantly saying goodbye to him these days. She'd like to say that she'd become used to the idea, but the truth was she still felt like her heart was in her throat whenever he went away, something he liked to tease her about constantly.

Don't you know I'm greatest shadowhunter of my generation? He would say to which she would role her eyes before making him promise to be careful. He would never agree to be careful of course instead promising he would always come back to her alive. She'd stopped asking after a while, both of them knew that careful was something he could never promise to be. Instead she would simply tell him I love you Jace. I'll see you soon.

A knock on her door broke her out of her thoughts. "Yes?" She asked not looking up from her work.

"Is that the way you great everyone or am I just special?" Came the voice she'd been missing for days as her head snapped toward the door a wide smile lighting up her face.

"Jace." She breathed out, relieved as she stood, practically running and throwing herself into his arms.

She felt more than heard the chuckle as his arms circled around her, his face buried in her hair. "I thought you were still going to be a few more days." She commented as she pulled back, taking in his soft expression.

"It turned out to be easier than expected so I came back early. The team is just wrapping things up and they've got Izzy just incase anything unexpected comes up. I'll send you the report when they're done." Jace smiled widely, cupping her cheek gently as he finished with the formalities. "I missed you." He muttered tenderly before pulling her in for a long drawn out kiss that left her feeling breathless in the best way possible.

Clary placed her hand on his chest letting her eyes take him in as she pulled away. "You did huh… how much?" She teased, enjoying the feeling of being close to him again.

Jace smirked. "How much did you miss me?" He countered bringing his other hand to rest on her hip.

Clary rolled her eyes but only half heartedly. They both knew that she actually liked the way he teased her, though she would never say it out loud. After all, someone needed to keep his ego in check. "Who said I missed you at all? For all you know I'm perfectly content when you're away."

Jace raised one eyebrow nodding his head in mock disbelief. "Well, I guess I'll have to give you a reason to miss me more then…" He winked as he reached behind him to close the door, turning the lock.

"Now now mister Herondale…" Clary tisked. "Whatever could you have planned that requires a locked door?"

Jace's hands slid over her hips to grab her ass and he pulled her against him forcefully. "I have a few ideas." He muttered, enjoying the way Clary's breath hitched at the sudden contact.

"Well…" She started unsure of her voice for a moment before collecting herself and pulling away completely to his surprise. "…It'll have to wait." She stated reluctantly. "I still have a ton of paperwork to get through today." Clary leaned up placing a quick peck to his lips and went back to her desk, more than a little aware of the growing ache in her core screaming at her to take a 'break'.

Jace let out a dramatic sigh as she sat down and walked over placing his hands on the desk towering over her. "Now now Clary, it would be a shame to waste a locked room during a moment of quiet as head of the institute. You never know when we're going to be disturbed." He didn't 100% seem displeased with the idea, a wicked glint in his eyes. Ever the exhibitionist.

Clary twirled her pen around in her hand, leaning back in her chair curiously. "What are you proposing exactly?"

A wide grin spread across Jace's face. "That I help you relax." He held her gaze as he stepped around the desk kneeling before her, placing his hands on her knees, squeezing gently. "You don't even had to move, just… sit there and enjoy." He winked and Clary tried to hide the raging surge of desire she felt at his insinuation. Jace had had mastered every possible movement of his body and his tongue skills were no exception, in fact sometimes she thought they were better than his shadowhunter skills.

"Okay, fine." She agreed, tossing the papers aside as she grabbed the collar of his jacket and pulled him in for a passionate kiss, while he manoeuvred himself between her legs sliding his hands under her skirt to grip her bare thighs.

His lips moved over hers as they always did when he returned home, hungry, rabid, as if he might never get the chance to kiss her again. She loved it, loved the feeling of knowing exactly how much he missed her, how much he wanted her, even after only a few days away. He slid his tongue over her bottom lip, sucking there before she could respond and pulling back just enough to rest his forehead against her's enjoying the way her breath came heavy as her fingers entwined in his hair.

"Now then…" He breathed out, only partially as breathless as her as he kissed along her jaw to her ear. "I believe I was going to help you relax." He whispered low, his voice like melting honey, making her shiver under his touch.

"Well go on then…" She encouraged, her breath hitching slightly as he started kissing his way down her neck, his hands sliding up to her hips, teasing under her soft lacey panties.

"I love this dress on you by the way." He commented as he admired the black and red patterns with a soft neckline that gave him just enough space to press his mouth over the top of her breasts, enjoying the light moan that escaped her lips at his increasingly passionate ministrations.

"You can thanks Izzy later." Clary muttered between her laboured breaths. "She insisted I needed some more professional attire."

Jace chuckled lightly as he kissed his way back to her face, holding her gaze as he let one of his thumbs lightly graze her outer labia, knowing if he angled just slightly further that he would be able to feel how incredibly wet she already was. "I will thank her personally." He muttered, letting his other thumb graze over the same spot, gently massaging over her, parting her open before letting one thumb slide through her wetness, enjoying the sudden gasp that fell from Clary's lips and the moan following as she held his gaze as started stroking over her.

Clary leaned in to kiss him, only able to hold the kiss for a moment at the feeling of his fingers stroking over her. It was too much and yet not enough all at once. "Jace…" She gasped out as his lips attacked her neck again.

"Yes my love?"

"I need more." She managed to get out between him sliding one thumb inside of her while circling her clit with the other.

"More of what?" He prodded, determined to make her demand what she wanted from him.

She had to take a moment, caught up in the sensations he was creating. "Take off my panties and put your tongue to good use." She demanded before another moan escaped her completely outside of her control.

Jace placed one more gentle kiss to her neck before moving his hands to hook his fingers under her panties. She lifted her hips slightly bracing herself against the arms of the chair as he slowly dragged them down her legs, tossing them aside. They shared a wicked grin as he pulled her hips slightly forward instructing her to recline back as he shifted her dress up just enough to lift her legs over his broad shoulders as she leaned back, her core glistening before him, begging him to taste her. He quirked a cocky lopsided grin before lowering his head and dragging his tongue slowly deliberately from her opening to her clit, eliciting a low moan from her as he dragged his tongue down before repeating the process over and over, enjoying the way she swelled under his mouth and moaned his name in appreciation.

Jace had heard a lot of guys complain about pleasing women this way, but he had always loved it, though admittedly he had never been so generous with his mouth as he is with Clary. It was more than the fact that he loved her. He wanted her to feel it in her body how much he wanted her, how much he enjoyed her pleasure as much as his own. He found himself enrapt in the sweet taste of her, his lips and tongue craving to touch her as much as every other part of him. He explored her folds, circling around her clit and around again, hands massaging over her inner thighs as she opened to him, hungry for his touch.

"More Jace…" She moaned louder. "Please… more… inside…"

He took the hint probing a finger inside and then two, enjoying the silky smooth feeling and the clenching of her muscles around him as he angled them up, stroking over the spot that drove her wild as he continued working his tongue over her. He could tell she was trying to stifle the volume of her cries as she instructed him on… harder… faster… right there… oh Jace… yes… oh god yes!

She tangled her hands in his hair and he had to grip one side of the chair to stop her from rolling away as she started thrusting her hips in time with his fingers, teetering closer to the edge with every stroke, completely enrapt in the moment, unable to quiet herself anymore. He alternated between sucking and swirling circles around her clit as he thrust his fingers inside of her increasing in speed and intensity until she felt like she might literally explode of she didn't reach her peak soon.

Jace seemed to sense how desperately close she was, angling his fingers with just the right amount of increased pressure, tongue committed to circling her clit until she felt her walls contract around him savagely, a loud gasp escaping her lips as she felt her orgasm explode through her, expanding, racking through her body as if he had reached in and caressed every part of her. She felt herself relax slowly, her legs tingling as he gently stroked her down, her body involuntarily jerking as he stroked lightly over her clit until she told him to stop, completely satiated… at least for now.

He helped her legs down from his shoulders and then wiped his hand over his face sucking her juices off of his fingers as she placed her hands either side of his face. "I feel… very relaxed now." She stated, her face glowing with satisfaction.

Jace pulled her in for a brief but soft kiss lingering after as they nuzzled their noses against each other. "To answer your question, in case you haven't realised, I missed you a lot." He stated seriously, enjoying the calm of her afterglow.

"Hmmm…" She sighed contentedly. "I could tell."

"Well, I guess I should let you get back to work." He stated gently, pulling back to gaze at her, a proud smile crossing his face.

"You sure you don't want me to return the favour?" She asked quirking one eyebrow suggestively.

Jace groaned lightly, more than tempted. He needed to step away now or someone would get impatient and use an unlocking rune to demand their attention. "Later." He finally answered, standing and holding out his hand to help her up as well.

She retrieved her knickers which had landed on the edge of one of the paintings, sliding them on quickly, not oblivious to the sound of chatter from outside the room. She blushed slightly as she met Jace on the way to the door. "It would appear that we have an audience out there." She stated at which he chuckled lightly.

"Well at least there will never be any question as to whether I please you miss Fairchild." Jace remarked, a cocky grin spreading across his face. Clary smacked his arm playfully but Jace just leaned in pressing a tender kiss to her forehead. "I'll see you later." He muttered before opening the door to see Alec standing at the front of a short line of people waiting, his arms crossed in almost annoyance.

Alec cleared his throat deliberately as he stepped in eyeing both of them like naughty children caught in the act. "You two do realise that you have a room for this kind of thing." He commented, letting Jace stew for a moment before clapping him on the shoulder a little awkwardly but with a hint of pride, insisting Jace wash his hands before touching anything else.

This wasn't the first time he'd overheard her and Jace in the heat of the moment. She was certain that most of the institute had heard them at some point by now. It was practically common knowledge these days that they were to be left alone, unless it was an emergency, whenever Jace returned from mission. Alec, while not exactly complicit in their escapades, had played a hand, along with Izzy, more than once in ensuring they were not disturbed, simply stating that as long as Jace was happy, he would be willing to put up with the occasional noise, but would seriously prefer it if they would kindly remember to use a silencing rune.

Clary blushed as she watched Jace walk away to the amused glances of the others waiting, before meeting Alec's gaze. "So…" She began awkwardly noting the veiled amusement in his eyes. "You wanted to discuss the downworlder alliance?"
