Duke's words made Yuri's enthusiasm deflate. She was happy that she gained the dominant position and wanted to fight back, but Duke's words brought her back to reality, she was not the dominant one right now.
Out of nowhere, Yuri felt a gentle burning on her ass that made her wake up from her stupefied state. Duke had spanked her, to wake her up, and he finished by saying, "Come on, beautiful, move your ass."
Despite how rude the comment seemed, for the women of this country, it was not considered an insult, but rather an extension of the man's dominance in bed, and although reluctant, Yuri began to move her hips up and down.
Yuri was an experienced woman in sex, so Duke was having a hard time trying to resist Yuri's hip movement, but he still didn't let himself be overwhelmed.
