Her Panties

Not realizing she forgot to put on her panties, Ruby rushed to the classroom where the test took place. As she was rushing, she tripped over a lose tile and lost her balance. This caused her to fall on her butt, and as she opened her eyes she saw her reflection in a window of a (thankfully) empty classroom and realized her predicament.

"Nononono!" She immediately covered her exposed crotch with an enormous blush. Contrary to popular belief, she didn't wear the kind of stockings that were designed like pants, but the kind of stockings that only covered her legs. She didn't like the feeling of the pants-like stockings, but didn't believe that something like this could ever happen.

Quickly looking around, she stood up and rushed towards the classroom again. She didn't have the time to go back and put on panties, she was already pressing for time as it is. It would've been disastrous if she got late. Now aware of her pantyless status, she felt every breeze stroking her pussy, adding to her embarrassment.
