Fire alarm

Sandry was about to take her seat when an ear-splitting ringing came from overhead.

"Fire alarm." Miss Lane said, "Everybody out, leave your things."

"Miss!" Sandry exclaimed as the class began to file out of the room, "I can't go outside like this!"

"You should have thought of that before you came to class naked." Miss Lane shrugged.

"I didn't..." Sandry began, but Miss Lane had moved away to lead the class out, "Oh, dear..."

The entire school gathered on the playground, all lining up by class while teachers supervised. A sea of blue and grey uniforms. And then right in the middle, an island of pale pink as Sandry, crouched over to make herself as small as possible and with her arms clinging to her crotch and around her breasts, stood there nude.
