"what are you doing?"
your meek voice could be heard from where you sat on the bed, jace's bed from inside the institute, clad only in one of the boy's oversized shirts, nothing beneath.
jace walked back towards the bed with evident cockiness in his expression, you were sure that he couldn't shake it even if he wanted to. "just putting the silencing rune on the door." placing his mouth against your neck and his hands against your waist, unable to think of anything other than you.
your voice was above a whisper, hands roaming towards his neck. "promise?" because though he was a shadowhunter, he could still lie. a disadvantage you were seemingly always caught up in.
he parted his mouth from your neck, cocking his head to the side with a playful smile on his lips. "don't you trust me?" as if the question had been one that didn't need an answer, he'd press anyway.
your mind danced to the flashback when jace had told you he'd put the silencing rune on the door and yet as you walked out of the room the next day, you earned many stares and glances. jace had smirked at that, once confronted stating that you were his and everyone in the institute should know so. "not really." you answered honestly, voice low as a mouse.
a low chuckle fell from the blonde's lips, eyes tracing your face. "i love that you can't lie."
you, not so much.
there were many things you could have went your entire life without telling jace but when presented with the right questions, you had no choice but to answer with the truth, unable to will a lie to stain your tongue.
your own eyes traced his face. you could feel the gentleness of his fingers against your thighs, they'd moved from your waist to the nakedness of your skin, inching just below the shirt that he'd drawn up more than he'd care to admit. from earlier activities, he knew that nothing lay beneath the shirt, it only egged him on more.
his eyes bored into yours, a grin against his lips. "you really love me, don't you?" it was more of a statement, not a question. he could see it in the way your eyes couldn't leave his, the way they traced his skin so gently. you two weren't exactly 'exclusive' just yet but he was yours and you were his, it was all that mattered to the both of you.
his fingers gently moved upwards causing air to trap in your throat. "you already know the answer to that." stating the truth but unable to admit what so desperately scratched at your tongue.
around him, you couldn't be held accountable for the tales you would tell.
"no lies there." he answered, lips attaching and detaching from your neck again. "but i want to hear you say it."
his hot breath against the nape of your neck along with the tone of voice he spoke in, one of certain demand, as if he were giving you straight obligations. it was enough to have your face hot and your hands clawing at his arms.
you didn't have to be inexperienced to get so flustered around jace, it simply happened. your voice was strained, holing in a mewl at the edge of your tongue. "i can't." voice broken and shattered.
it was hard to keep a steady breath when his fingers travelled further up your skin, lips sucking on the skin of your neck, creating what he'd soon assure you was simply a 'love bite' and assure you that it was nothing to be embarrassed about, convincing you to wear it about in the institute and have people look at you funny.
"yes, you can, angel." his voice reassuring and soft, his fingers gently squeezed at your thigh. however, you answered with only a shattered gasp leading his fingers to trail further and beneath the cotton shirt over your frame. "come on, baby, say it." voice a breathless whisper against your exposed skin. "lemme hear you say it, come on."
being a seelie, you were bound by the truth, unable to lie.
however, jace herondale was the reason your mouth would spew so many words.
he couldn't force the words out of you, that wasn't how being a seelie worked, he could make you talk. but he had such a good way at making you do it, manipulating your lips into moving.
perhaps it was the gentle hand that moved upwards to your pussy, collecting the wetness of your core and causing you to whine, the feeling of his thumb sinking down on your clit and gently circling it. "say it." he teased, smirking close to your cheek.
"i love you."
and jace wore a look of satisfaction, knowing you couldn't lie, knowing it had been the truth.
"good girl." left his lips, sinking back onto your neck and allowing the first finger to enter your core. you shook, your face pushing into his shoulder and muffling your noises. "wanna hear you." is all he mumbled back. "silencing rune is on the door, baby, no one will hear you but me."
and didn't that sound like an offer you simply couldn't give up.
once again, jace herondale managed to put you in a position where you couldn't so much as fight it. a whine left your lips, feeling him add a finger into your core and pump them in and out without grace, rapidly.
you had this thing about you, beautiful soft and slow. jace would like to add that he was quite the opposite. and he relished in it. he relished in using his fingers to ram inside your hole, the palm of his hand hitting against your clit and causing enough stimulation to have your back arching from the bed, hands pawing at him like a kitten, trying to hold onto whatever sense was left in your head, using him to ground you.
however, the more you grasped at his big arms, caging you, the deeper you fell.
it was almost impossible to will your mind back to reality and jace didn't bother to help. on the contrary, he pushed you even further.
"good girl, good girl." smiling gently as he repeated the words to himself. his free hand came down on your face, thumb swiping across your bottom lip and watching as your face scrunched up in emotions you couldn't quite string together. "such a good girl f'me, huh?" words as much of a tease as they were a praise. "my pretty girl, yeah? you my pretty girl?"
and you were so far gone that you couldn't register the words that moved from his mouth to your ears, nodding and babbling incoherent words, whines and whimpers stretching from your mouth.
finally, you felt the familiar knot inside your stomach and the boy did nothing to stop his movements, willing you over the edge until finally he felt your juices on his fingers. he brought his hand up to lick them off, watching as your eyes shut and your pawing hands pulled him closer.
this time, he moved with your hands, coming closer to your body and letting you grasp onto him, the only reality left.
and the words seemed metallic on your tongue, unable to string anything else together. "i love you." you whispered, hopelessly. "i love you." like a prayer on one's dying tongue.
there was something eerily comforting to jace, knowing you couldn't lie to him, bound only by the truth.
i love you too repeated in his own head, willing it to move to his tongue. jace wasn't like you, he had the option to lie, though he'd never do such a thing.
yet he found the words harder to lift onto his tongue, unknowing if you'd ever believe him in the assuredness that he believed you. perhaps it was everything he was afraid of.
which is why he said nothing.
