Does it work?

No

She felt power flowing through her wand, but instead of seeing her white panties floating back to her, she felt her skirt being expelled away from her!

She tried to grab it, but she was not quick enough, her skirt landing further away than the underwear, beneath the chair of the student in front. "Ohfuck...fuckfuckfuck! This can't be happening!" She looked down, seeing her red bush right between her pale thighs. She immediately crossed her legs and used one hand to cover her crotch. Her face got almost as red as her hair. And she could feel that she was getting horny because all of this!

"Fuckfuckfuck! What is happening?! I'm bottomless in the classroom! And I am getting wet... I can't believe this!" She thought of what she could do. She did not have many options. She did not even have a cardigan with her today.

"Pleasepleaseplease... work!" she said to her wand.
