She tells them she's fine

"I'm fine," Kirsty said a little too quickly. "Just nearly dropped something that all."

She felt herself shiver for a moment as the two security guards still had their attention locked on her, and she was worried for a moment that one of them was going to come over. It was likely only a few seconds of panic, but it felt like hours as she stood there, legs spread, panties on display, just willing them to look away.

Finally they did and Kirsty relaxed, having the unfortunate effect of dropping her skirt all the way to her ankles, but at least the guards were no longer looking at her. Hopefully she'd now have time to get her skirt back up.
