Spank Sophie’s ass again

It looks like the angry pinkness of Sophie's asscheeks has faded a bit, so you decide to give her another round.

This time you bend her over your knee like a recacitrant girl, and give her twenty more spanks. She struggles under your grip, but it's clear she's not struggling against you - if anything, she's practically leaning into you for support - instead, she's struggling against the pain, which she seems in danger of being overwhelmed by.

You let her up, and she tries to rub her ass, but since her hands are bound in front of her, she can't reach. You have her kneel again.
