Her panties drop to her ankles

Anna took a step away from the alcove, but apparently, when she ripped the tag off, her waistband had torn as well. This caused her panties to quickly descend and land around her ankles. Not able to react in time, Anna took another step and invariably tripped due to her ankles being bound.

Her panties ripped, leaving them hanging from one ankle as she fell on her stomach. When she hit the floor, her skirt lifted, and her legs flipped up. Her torn underwear flew off her ankle and landed on her face! She only had a second to react before something worse happened...
