Just strip her naked

No more negotiations. You speed up and relieve her of her panties, yanking them down hard. She is now standing naked from head to toe in the middle of the market square.

When time speeds up she sees she’s naked and shifts one arm back to covering her crotch, leaving the other on her breasts.

She squirms uncomfortably, letting out a humiliated moan and constantly adjusting her arms to try and cover herself up. Literally seconds earlier she was a haughty, fully armed and dressed knight charging at you, and now... embarrassed, naked, submissive. Her confidence as gone as her clothes and her pride.
