[He lets out a thoroughly embarrassing noise of surprise when their mouths collide, but the fierce energy behind it makes him shiver, open his mouth to Harry without even pausing to think about it; he feels claimed, which is precisely the opposite of what he wants to feel, but it elicits a strange sort of excitement.
Still, everything about his reaction reeks of indecision: his hands don't move to touch Harry at all, arms hanging limply at his sides; he follows the kiss rather than ever making a move to lead it, which goes against every part of his nature that he's shown so far; every now and then he pulls back just a little, as though wondering if it should be over, and that makes it obvious that he's not fully into it. Excited, yes, and very curious, but not fully out of his own head.]
