You change your mind and retrieve her

You enjoy the sight of her running away, arms clamped across her torso and ass shaking, but you change your mind. You've decided you're not letting her off that easy after all. She challenged you and lost, so she's going to have to suffer the full brunt of her defeat. You zip back and forth at tremendous speed across the square to the stack of the girl's discarded clothing to get some straps and back to the escapee, return her, and then move her up against a thick pole from the wooden structure that surrounds the square, which normally provides space for market stalls.

It all happens so fast, she barely has time to discern what's happening before she comprehends she's tied up. You've tied her to the pole, using her bra, garter, belt and various of the straps and buckles from her armor.
