Oh.

My calves slam into the frame of his bed and an agonisingly sweet shot of pain rockets through me; I can't help but moan, softly, and he smiles against my mouth, a sly, devious smile I can see in my head. My tongue continues to tangle with his and the gentle squeezes of my waist send my brain into overdrive. This is so hot and intense and yet he's lacing every action with some careful -I suspect calculated- movement that's confusing my senses and making me dizzy with desire. His hands slide effortlessly down my hips, ones that jut out from my skin like tiny daggers, and he unleashes his claws, torturously dragging them down my ass, where he grips onto me and he moves his lips over my cheek, just to hear me gasp louder. As easily as before, he pulls back over my hips and begins to undo the button of my jeans, still kissing me. But then he stops. He breaks the kiss and takes half a step back. I worry for a moment that he doesn't want me, and that this must end, but the devilish glint in the serpent-like yellow of his eyes says otherwise. He stares into mine, with pupils so swollen I fear the green in them has been nearly swallowed whole, and I know he can see the hold he has over me. I catch him almost smile again, but he's too good to let his expression slip. His fingers pinch the zipper and I wait, nervous and buzzing, to see what he'll do. You could cut through the tension with a knife.

"Look at me." His voice is steady, kind, but it's an order. I train my vision on his eyes and he smirks a little, and I see them gleam brighter for just a second; in the silence, he holds my waistband between his thumb and finger and uses the other two to drag my zipper down, so slowly it's murder. Such a power-play... Quicker than I thought he could move, my jeans are pushed down my thighs and I'm on the bed, propped up on my elbows. His fingers glide across skin and denim until he pulls my stilettos off and throws them to the floor. He turns his attention back to my clothes, and peels them down my legs, so I can feel every fibre stroke my skin, tugging them off at the ankles to join my heels. He climbs onto the mattress, straddling my legs, and pushes me further up to gain access to them. He leans forward, slowly, like a cheetah about to pounce, and lowers his face to my thigh. His soft, sweet kisses burn my aching skin and I feel my blood scalding new pathways inside me, igniting something hot and intense. I catch my breath and he lightly scratches my other leg. He begins pressing harder into my skin and I can't resist the urge to moan a little more. Once again, I feel him smiling, enjoying the control he has over me; I'll admit I'm enjoying it too.

His teeth nip at my flesh and I moan so loudly I'm nervous the rest of the Institute heard. This time, he actually laughs into my skin. He starts to get up and I'm worried I've made a fool out of myself, but instead he just pulls his shirt over his head and casts it away to the pile of clothing forming on my floor. I can't help but stare in fascination at his perfect figure: smooth flat stomach, ribbed with strong, golden muscle, and protective, arms, corded with even more. He suits his shape; he's not overdone it, it just looks beautiful. His hands slip under my back and lift me forward, breaking my thoughts. His lips connect with my neck and sear my skin, and I instinctively brush my hair over one shoulder, tilting my neck. My throat is vulnerable and exposed, and he loves it. His kisses become more furious and quicken so I almost fall back against the bed in a state of overwhelming ecstasy. If I thought that was too much to handle, I get a shock the second he pulls the flesh of my shoulder into his mouth, clamps it lightly with his teeth, and begins to suck... hard. Nothing has ever felt so incredibly, impossibly heated.

"Jace... Fuck, Jace, I love you..." I moan, throwing my head back, and he stops, looking into my eyes.

"I love you too, Clary. You're mine now, right?" The gentle edge to his voice makes me feel so safe and happy, but the last sentence drives me insane, awakening my kinky side again.

"Fuck, yes, all yours. Show me..."

He smiles again, the same cunning smile as before, and returns to the same spot on my shoulder as before. It's even better the second time, because the skin is so sensitive and tender from before, and I grip onto his shoulders, my short, clipped fingernails digging into him. He sucks harder and harder until he pulls away, letting the skin slip back between his teeth and back into place. I sigh, my breath shuddering from my throat, and he pulls my shirt and tank top off, so they, too, join the pile. He kisses down my throat, my chest, my ribs, my stomach, my hip... and finally nips at my lacy underwear with his teeth, just like my shoulder, and drags them down my legs, spreading them gently with his hands. His thumb goes to work, expertly, on my clit and he flicks his tongue over me, making my back arch up from the mattress, moaning uncontrollably... I don't want this to stop, ever, but it's so much pleasure to handle I'm not sure I can take it... It's so good... so good...

And then his phone buzzes. FUCK.

He lifts his head but quickly regains a look of complete and unadulterated mischief, and licks, fast and hard, making me squirm. He gets up and pulls my underwear up for me, replacing my other clothes and his.

"Sorry, you know I've got to..." He points at the door, apology in his expression.

"I know... Damn you, Jace!" I smile.

"I'll make it up to you later..? I really have to run, Clary..."

"Go! Go! Have fun with Alec and don't forget to slap him if he whines about Magnus for too long. Unless there's juicy gossip, in which case spill when you get back, I want all the details." I say.

"Of course, baby. I love you." He promises.

"I love you too, see you soon, Jace." I smile.

He walks out the door, and I lay back against the mattress, still burning way too bright.

"Oh, by the way," I shout out after him, "You're a bastard for leaving me like this!"
