Ianto had been trying to work out what he had meant by 'done this with an audience' -- the physicality in general? Pulled this sort of a trick before -- but no, that's supposed to have an audience. He flicks his eyes across the other man's face and he's meaning to ask him about it, when John tugs him forward into a kiss.

Oh, Ianto thinks absently, his fingers tightening convulsively where they rest against the other man's shoulders and his waist. The hand on the back of his head is nice but there's not a chance in hell he'd pull out of this earlier than he must, as startled as he is. He's only allowed himself to do this once before with John, after all, and there'd been a great bloody dragon bearing down on them. This time at least maybe they might enjoy a little.

With a small noise against the other man's lips, Ianto presses forward right back into him. He doesn't really need to play it up to their audience, considering how much he's wanted this. Well, perhaps not this specifically, but certainly this kiss, John instigating it, and the other man's arms around him, holding him as close and tight as they are.
