Notes: Written by an ask on tumblr. I was prompted to write a first time/praise kink drabble for this ship, so... here it is.
"You're doing well," Sebastian murmurs in his ear on yet another thrust and Jace buries his head into the pillow next to him and bites down on his lower lip once again. They've been at it for so long already and he's really been trying to keep himself quiet, even if it hurts by now; the skin stinging from the repeated abuse of his teeth and Sebastian's erratic kisses. But, you don't want half the Institute to know that I'm here, do you, Jace, and no, that definitely wouldn't be ideal. No Institute is without its prejudices where newcomers are concerned and they both know it. "You're doing so well, Jace." Another kiss, this time just below his ear, then along his jawline. "I knew you would."
The words are enough to make him shudder, and it's embarrassing, as much as it is addictive – it's not like he hasn't been complimented before, or had his abilities admired, both inside and outside of the bedroom. But he's never been the centre of this kind of focused attention and it's making him squirm and press himself even more firmly against Sebastian as he finally increases his pace. It had hurt at first, but he'd got used to it gradually and now, he just wants more of it, whatever it is.
"You're perfect, aren't you?" He doesn't seem to require an answer, and Jace is glad – he's not quite sure he could give him one. What is he supposed to say to that, anyway? He's still trying to figure out why Sebastian's words affect him quite so much and how he's managed to find out that they would when Jace himself hadn't known, even though it shouldn't be a surprise at this point – Sebastian had apparently figured them all out the moment he'd met them. When he speaks again, it sounds like a revelation. "You would let me do anything to you."
Yes, yes, yes. He doesn't even care what everything consists of, as long as he just keeps talking.
"Perfect," Sebastian says again, and Jace chokes on his name as he comes.
