"I have to insist."

Beth, sitting next to Meg in their shared Occult History lecture, wriggles uncomfortably in her seat.

Underneath her long skirt, she’s wearing panties made from extra-itchy Vatican sackcloth, plus a tight crotchrope. You and Meg gave her an extra-hard spanking before today’s class, and the sackcloth is irritating her sore, sensitive red ass. So it’s no surprise she’s uncomfortable.

“Now,” says Professor Susan Smart, “Most of today’s lecture will be spent discussing the upcoming exam period. But, first, another one of those demonstrations I’ve become so fond of. Beth, Meg, kindly come to the front of the class.”

“No thank you, Professor,” says Meg, politely.

There’s a stir in the crowd.

“What did you just say, Meg?”

“I said I don’t wish to volunteer today, Professor.”

“Meg!” Professor Susan Smart, a voluptuous raven-haired Englishwoman with her glasses perched on her nose and her breasts straining against her tight white blouse, seems completely taken aback by this. “Participation is mandatory! I have a number of skyclad witch dances I need presented to the class today, and if you don’t assist, I shall have you expelled!”

“I don’t think you can have me expelled for that, Professor.”

“But… I… but…”

“Maybe you should demonstrate the dances yourself, Professor,” says Meg, her voice sweet as honey. “In fact, I think you have to. Because if you don’t I’ll, uh… tell the Dean what you’ve been up to. You wouldn’t like that, would you, Professor?”

“That would be most inappropriate!”

“And why doesn’t your little teaching assistant there assist you?” says Meg, pointing to Amy, who’s trying to slink out the side door before anybody notices. The class leans forward expectantly. “In fact, Professor, I think I have to insist.”
