A skirt?

"Hey look," a voice called from outside the stall. "Someone's left a skirt by the door."

Yasmin and Steph stared at each other as they heard the sound of giggling, and joking, but couldn't make out what was said. Instead they both slowly looked downwards.

Steph's legs were indeed just as bare as Yasmin's, made even worse by the fact that she'd already sacrificed her underwear. Her bare pussy was on full display, naked now from the hem of her shirt to the tops of her socks.

Yasmin looked like she was about to say something, but Steph stepped closer, pressing her hand over her friends mouth. The last thing they wanted to do in this situation was draw attention to themselves.
