Be a live model for the sex ed class

"You are eighteen, right? Definitely eighteen?"

"Yeah. W-why?"

"Okay, then there is a way to make this legal. The only way to justify a student being naked, and...doing what you have just done. It could also excuse the classes you skipped, I think."

"R-really? You'd just forgive that?"

"No, I don't. It's just that, after what you're about to do... you've probably been punished enough."

What was that supposed to mean? Surely there wasn't anything worse than being expelled? Now acutely aware of her nudity and her arousal, Anna tried to position herself a little better, to hide more skin. Maybe she could ask to get her clothes and get dressed before they implented whatever 'plan' Mr. Jones had come up with.

"I will have you retroactively sign an agreement to be a live model for health class."

"W-what? Oh, okay... can I get dressed again before we do that?"

"I don't think you understand. I'll have it look like you agreed to do this a week ago. So you can feasibly do it today. Right now. For this sex ed class. And... it will have to entail what you've been doing right now, or else the students won't buy it."

This time, Anna did get it. And it made all the color drain out of her face. Her mouth was agape. "I'll have to... in front of everyone... is... is this a joke? There's no way this is a solution..."

"I'm afraid it is, and it's your only shot. It's even one of the demonstrations that's being recommended in case a live model is available..."

"No... no! Th-this can't be it! I... I can't..."

"Well, you already did, just now. I would tell you it's just a repeat performance, but... the whole lesson will revolve around you, and I'm afraid they'll see a lot more. Up close. I'm sorry, but it can't be helped. Remember, you can only blame yourself for this situation."

Anna was speechless. Just a few minutes ago, she had enjoyed the thrill of doing something naughty, being free of her clothes, and imagining the complete exposure that she risked. Now, she was seen, and even worse, the little daydream she had was about to become reality...? Not only for a few seconds or minutes, or for one shameful act of masturbation, but for a whole class period?

"Anyway, we wasted enough time already. If we keep babbling any longer, the students will get suspicious. I will go out there, introduce you and explain why you are here, and you will come out when I call you. And keep in mind, for this ruse to work, you mustn't cover yourself. Just enter the room as if you were clothed, and then follow my instructions."

With that, he went back to the classroom, leaving Anna alone to contemplate her fate. She didn't really say she was going to do it, but what choice did she have? This really was the only way to get out of serious consequences. Or is it?
