"You are absolutely wonderfully warm," Krem confirmed. He watched Thomas check his skin, as if he expected to be able to tell his own temperature just like that.

It occurred to Krem, briefly, that Thomas had spent quite a lot of time around other boys his age and probably knew all about how warm they were just by proximity of bodies that happened in those situations. Krem, meanwhile, hadn't been around a teenager since he was one, except for Noah and Thomas.

Krem swam a little closer to Thomas, smiling at him. "I like the warm."
