Let it be a frenzy, then -- the lock slides into place with a click, but it might as well been the starting bell before a horse-race. Nero is on Cid, all but grabbing him by the ears to pull him to him for hard kisses, bending to give them even though it'll leave a crook in his neck and sore shoulders, with how hard they're going for it.

Nero wants it so much, he doesn't care. If he's sore (and he better be) by the time the night has passed, then so much the better. He wants all that pent up energy that builds and builds between his absences.

He wants Cid at his most needy, because then they can't find excuses to deny this.
