Dorothea makes a little sound of surprise when Itto dives directly into her cleavage, but she shouldn't have expected restraint from him. That forked tongue works its way around one of her nipples and it's her turn to moan. That's... not quite like anything she's where felt before.

He seems to like her breasts well enough, so she decides to let him play for a while just to see what he does. Maybe his curiosity will lead him somewhere interesting.
