There was no way she could stay hidden here, Sandry decided. She eased herself up onto her haunches, and as the group made their way around one side of the desk, she sprinted away from the other.

There were exclamations of shock from behind her as the pupils struggled to process what they were seeing.

"Who's that?!"

"I dunno, but she's naked, right?"

"Definitely."

"Good, I thought I was seeing things."

"A streaker?"

"In a classroom at 11am? Who does that?"

"Maybe she's practicing before the game on Friday."

"You don't need to practice streaking."

Sandry did not hear most of this conversation, as she threw herself through the doorway and back into the corridor, once again nude in the middle of school with no idea what to do.
