Math class

"Math," said Ruby Chow, the tall, acerbic but undeniably attractive math teacher, "is really stupid. Today's lesson, therefore, will be about how math is stupid, and how math teachers are all arrogant, stuck-up bitches who think they can push around really important people like homecoming queens just because they don't know some stupid thing about quadratic equations."

She undid her crisp white blouse as she spoke, letting it slither to the floor to reveal her lacy black bra, concealing small but perky tits. "The truth is, I'm just jealous of how much smarter and prettier Anne-Marie Patchett is than me. I can't even do math. Nobody can. It's all made up. I'm going to spend the rest of the lesson in my bra and panties, because I can't do math, because I'm stupid, and math is stupid too."

Her black pencil skirt joined the blouse, revealing lacy black panties clinging to slim but cute hips, stockings, a garter belt and high heels. "Look at me wiggling," she said, wiggling, as the class laughed and gossiped to each other about how much more fun this was than math. Anne, sitting up the back, grinned and put her feet up on the desk. Bonnie and Susie, still naked, sitting on each side of her, exchanged worried glances. At least they weren't the centre of attention any more.

"The only thing stupider than math," said Ruby Chow, "is Bonnie and Susie. Come up the front, girls. You're in trouble for being so stupid."

Reluctantly, the two naked girls shuffled to the front of the classroom, where they were greeted with a chorus of wolf-whistles and hollers. Ruby gestured for silence. She pointed at the chalkboard, where a bunch of equations were written.

"Solve the first one," she demanded.

"I can't solve that," objected Susie. "It doesn't make any sense. Anyway, you said math was stupid."

"Then you must be really stupid, if you can't solve it." Ruby's hand lashed out, and Susie yowled as the ruler made contact with her bare bottom. "You have one minute to solve the problem. If you fail, Bonnie will get spanked."

"That's not fair!" Susie's brow furrowed as she studied the question. 2+2=... what was it again? The answer was on the tip of her tongue. Everyone was laughing at her for not being able to figure it out, she knew, but somehow she just couldn't...

"Ow!" Bonnie protested, as the ruler made stinging contact with her bottom. "Susie, come on! It's not that hard!"

"I'm sorry!"

"Your turn, Bonnie. This time, if you fail, Susie will get ten strokes with the ruler and have to give you a kiss."
