At the beginning Lady Viktoria shakes her thighs and her whole leg. But that's just the prelude to the whole story. After that she stands in front of the mirror and lets her fat ass bounce. She really travels her big ass cheeks up so that they bounce back down with full force. What a sight... and you can watch the whole thing in slow motion. We wish you a lot of fun watching! It was fun for us too. Sincerely.
