[ On a bit of a whim, one he can't even identify until it just happens, Spock closes his mouth at the junction of Jim's neck and shoulder, biting down at the spot at Jim's groan. His teeth dig in a bit harder, in sync with Jim's own grip on his hair. Spock gradually increases the pace with every thrust; it's nowhere near their usual, manic encounters, all heat and speed and quick, needy release. Like stoking a fire between them, the deep golden embers start to flare in their bond as well. It takes a few minutes, but then Spock is rocking against Jim, building to that all-consuming fire of release.
But just before the embers and the heat in their bodies start to blaze, before the physical need to go faster can overtake them, Spock slows again, coming to a halt and holding Jim that much tighter against chest. Spock is almost painfully hard inside of Jim now, but he controls his own urge to keep going, keep moving into Jim in order for Jim to experience this. ]
