Sure, you'll give her some clothes back

"You want me to swap back your clothes?" You ask her

"Yes!" She screams, clutching her privates tighter.

"Whatever you say", you reply.

The knight is enveloped by a blur of motion, followed by a moment of disorientation. Then she checks herself, and she doesn't like what she sees.

She screams again, jamming her knees together and covering her boobs with both hands.

"All my clothes, I meant all my clothes!"
