The kiss to his fingers makes Hythlodaeus's breath catch in his throat - he's still rather partial to romantic gestures too, after all, a fact that may prove very useful to Hades in the future.

But if it was rendering Hythlodaeus speechless he wanted... well, he gets that and even more. He freezes utterly, staring at Hades wide-eyed as though in a dream, not even a trace of his usual cheeky demeanour left, his face completely red. He opens his mouth after a few moments, as though to say something, but it obviously doesn't come to him: instead, he makes a small flustered sound and then finally looks away, fingers digging into the sheets and his breath coming faster. He's also rather obviously, ah, excited, even before Hades touches him proper.
