Every sound Jim makes is endlessly distracting. It takes so much effort and self control to focus, to keep steady, to keep each movement grounded and measured and careful. Spock manages though, threading their fingers obscenely so soon as Jim finds his hand.

The tight heat around him is so, so much all at once, almost more than he can take without snapping. He manages this too though, rocking forward until he bottoms out, taking several grounding breaths as he looks down at Jim, eyes warm and expression fond.

Then, encouraged by Jim's frantic desire, Spock slowly draws back to the very tip, then snaps his hips forward to bury himself inside him fully again. The throaty moan it drags out of him is loud, and as soon as he has confirmation Jim is ready to continue, Spock starts up as steady as rhythm as he can right now, leaning over him to cover him with his body and murmur affections into his ear, painfully intimate in his emotionality.
