"Not that old," Ivan says in defense, because if Duv's old then Ivan only has a decade before he, too, must count himself as old. And frankly, he's not ready for that. "Just the right sort of old enough to be attractive," he continues, still talking even as his free hand is reaching for the small tube, "although normally it's the other way around. The older partner teaching the one new tricks--"

He is, at that point, sufficiently distracted by the feeling of Duv's lips on his to quiet him, although after a bit he does have to reluctantly pull back to kneel between Duv's legs. That is, at least at the moment, an unfortunate requirement.
