Hythlodaeus makes a curious hum at the advice - after all, it's true that he is the less experienced out of the two of them... but he did always pride himself on being a quick learner. He shifts his wrist position so he can reach deeper, curling his fingers as he explores.

And much as Hythlodaeus tries to remind himself that this was supposed to be just a little, it's so exhilarating to hear, feel Hades's reactions to what he does--so Hythlodaeus bobs his head down, taking more of his lover into his mouth before drawing up again. He tries to recall what it felt like to have Hades do this to him, tries to figure out how to replicate it - and even if Hythlodaeus is inexperienced, his attention to detail and natural inquisitiveness and willingness to both experiment and adjust help make up for it greatly. He establishes a slow, thorough rhythm, paying attention to how his lover reacts as, experimentally, he tries to take in more and more of him with each movement, slowing down a little to force his throat to relax once it starts getting more than he can easily take.
