"Camilla."

Camilla got up from her desk. She looked nervous, and as Miss McGowan handed her the pen, she looked at the equation on the board as if she had never seen anything like it before. It was possible she hadn't, I knew she did not always complete the homework.

"Whenever you're ready." Miss McGowan prompted her.

"Yes, miss." Camilla gulped, "I'm just trying to think whether I carry the one, or..."

"You don't."

"Okay then..." Camilla seemed to accept that she was not going to get this right. She reached her arm up to write on the board.

There as a snapping sound, and as the class watched Camilla's skirt fluttered down to land at her feet.

"Camilla!" Miss McGowan gasped.

"Sorry!" Camilla gasped, "The button was loose, I was going to fix it..."

She clapped her hands over her bright pink polka-dot panties, which clung to her and rode up as if they were a bit too small. Her face was rapidly turning red.
