The fire alarm goes off

A shrill bell suddenly split the air.

"Okay, everyone, let's go calmly and quickly." Miss Lane instructed from the front. The pupils stood, gathering coats and bags. "Leave your belongings, let's go."

Sandry wished she had a coat to wear, but it had been warm that morning. Hopefully warm enough not to make her too cold when she walked outside undressed like this, she thought.

As she filed out into the corridor her class joined all the others heading for the exit. She felt dozens of pairs of eyes on her, taking in the sight of her curvy nearly-nude body. She tried to cover herself with her hands but all this did was hide her underwear a little, it did nothing to hide her state of undress. All of her luscious curves jiggled and bounded as she went, she was aware of evety inch of exposed pale flesh on view for everyone.

And it only got worse as she left the building, joining the entire student body stood in the playground. All around her were pupils dressed fully, teachers and staff, and there was her in her skimpy underthings!
