Math class... naked!

The short, curvy brunette sat up at the back of the lecture theatre, clad in her trademark glasses and orange sweater. She wasn't watching the blackboard, though it was a very interesting blackboard, with lots of equations on it. She was watching the girl in the front row.

The girl in the front row was even more interesting than the blackboard, for a couple of reasons. The first reason was that she was naked. Naked women are always interesting. In fact, they're one of the most interesting things in the world.

But that wasn't the main reason the brunette - whose name, of course, was Velma - was interested in her. She was interested in the girl in the front row - whose name, of course, was Bev - because she was naked a lot.

The average woman, according to Velma's calculations, was naked in public only once or twice a month. According to her research, Bev was naked in public almost every day. A curious statistical anomaly. Indicative, perhaps, of supernatural activity.

Perhaps this was the source of the mysterious phenomena currently afflicting the campus.

It was worth looking into.

Yes. She'd have to watch Bev very closely indeed.

Bev, for her part, sat in the front row of the lecture theatre with her textbook pressed against her breasts and her legs folded together. She'd decided to sit in the front because it meant nobody could look back and see her body. All the students behind her could see was her long red braids and the nape of her naked neck.

Of course, it didn't stop them from noticing she was naked.

And the professor could still see her. Which was why she was folding her legs together and covering herself with her textbook.

And the people beside her could glance over and look at her.

All in all, she was still naked in class. That hadn't stopped being a thing that she had to deal with. But at least nobody could get a good look at her special places. Just the thought of it made Bev wriggle. Imagine having to present yourself to the whole class and let everyone get a good look at your private secret special places. Everyone would know all your private special secrets. It didn't bear thinking about.

But she was safe here.

Nobody was going to get a good look at her.

As long as she didn't have to stand up for any reason at all.

"I need a volunteer to come up and solve the equation on this blackboard," said the professor. "Anyone? Anyone at all?"

The room was totally silent.

"Come on. All you have to do is walk up here before the whole class, take the chalk, stand on your tip-toes, reach up to the top of the board, and write the answer in. Won't somebody put their hand up?"

Not a single student moved.

"If nobody volunteers, I'll have to pick somebody from the audience. Anyone of you, chosen completely at random."

Not even a pin dropped.

"Very well. I'll select..."

Bev held her breath.

"The brunette in the orange sweater, up the back."

Bev sighed in relief.

"What's that? I think I heard someone volunteer."

Bev squeaked, then tried to bite down on the squeak.

"Yes, I definitely heard someone. Who was it?"

Bev pressed her lips very tightly together and did her best to sink into the chair.

"Ah. The naked girl in the front row. You really shouldn't come to class naked, you know. Anyway, get up here. And leave that book behind, I don't want you cheating."

"But..."

"But what?"

"But I'm... naked..."

"So what? You can do maths naked. Some of the greatest mathematicians in the world were naked all the time. Archimedes was naked when he invented fluid mechanics."

"I don't..."

"Get up here now or you fail the class."

Bev felt the horrible, burning blush creep down her pale cheeks towards the freckled slopes of her breasts. It was awful. The professor was looking at her like he meant business. And everyone else was looking at her like she was naked.

She had a dilemma to face.

She folded one arm across her breasts and the other between her legs, and stood up. Unfortunately, that left her bottom bare. And her bottom was facing the class. Which meant the whole class was now looking at her beautiful bare bottom.

Which was one of her private secret special places.

But now everyone could see it. They could all see bare-naked Bev's beautiful bottom. Her pleasant posterior. Her delicious derriere. Her amazing, awe-inspiring ass. Her naked bottom. And her naked back, and her naked shoulders, and her naked neck.

But mostly her bottom.

And she only had two hands. If she wanted to keep her breasts and her pussy a secret from the gaze of the professor, she had to bare her ass to the whole class.

She took a single, tentative step forward.

Nobody said a word. But she could feel the heat of every eye in the lecture theatre, all focused on her unclad behind.

She took another step forward. Towards the blackboard.

And as she looked up at the equation, she realized all of a sudden that she had absolutely no idea how to solve it.

"Remember," said the professor cheerfully, "you're not allowed to sit back down again until you get the answer."
