Yuuri can't help that the noises that he's making sound a little pleading, but he doesn't ask for anything, just appreciates whatever Viktor is giving him.

That said, he's clearly quite pleased at the move to three fingers, his noises deepening and his hands clenching more in the pillows.

It's somewhat paradoxical, maybe, that Viktor's reward for a lot of hard work is to lie back and let him do most of the work, but it's something Viktor doesn't have to work for, and both of them understand the difference.
