John isn't sure what 'exactly that' has to do with anything he's just said, but at this point he'd rather forgotten what he was saying anyway. It doesn't really matter. Q is warm, and tight even with entirely too much lube. He's going to delight in kissing him for a bit longer, swallowing those little sighs.
His goal though, is to make Q find some more of those whimpering noises from earlier, and so John is not against a bit of not-actual cheatery when he crooks his fingers just so in the younger man.
