She flees

After being frozen for a few seconds, giving the class a good look at her curvy, almost-naked body, Sandry was overcome with the need to get out. She turned on her heel, kicking some of the rags that used to be her clothes in the process, and ran for the door.

Her teacher called for her to come back, but she had no intention of spending any more time being gawked at. Sandry skidded into the corridor, a vague idea of finding her locker, or going to lost property to look for more clothes, turned and hurried down the corridor.

It was like a waking nightmare, in the middle of school wearing nothing but an old faded pair of panties, a bra she had meant to retire as it was getting too tight, her shoes and socks.

Up the corridor, she realised she still had not decided where she was going. The library was in front of her, the nurses office with lost property was in the other direction, across the playground, and she could not try and cross that with no clothes on.

Voices were coming from up ahead, looks like not everyone was in class. Sandry ducked into the library, and hid behind a bookcase.
