"I've got you," he says through a smile. Taking his hand from around her stomach, he sucks on his middle finger to get it good and wet. Though she can't see, he makes sure to do it loudly enough for her to hear. Then he wedges the hand between them and drags the slick finger over her puckered hole just once before working it in. Like a little hook in her ass, his finger helps to keep her standing. Combined with the vibrator, they aren't enough to provide Yukiko with completely relief, but she won't be collapsing to the ground at least.

"You can come whenever you want, darling."
