_{[ Why? Why does he want to talk right now? It's distracting! Especially when Katsura is trying to do something he doesn't normally do. His tongue leaves the very end of Sakamoto's fingers as he catches himself a breath.
With a hot pant against Sakamoto's hand in annoyance, Katsura's brows pin together and he uses his other hand to completely cover Sakamoto's mouth. His hand squeezes slightly over Sakamoto's lips, dark eyes looking tense. ]}

Hush. You're doing it now— saying dumb things.
I don't want to hear that now— I want to hear something else, like your rapid breath.
Talk to me sweetly another time.

_{[ He'll simmer, cautiously removing his hand.
If Sakamoto makes another peep, though, the hand is going right back over those lips. ]}
