An audience

"I'll just have to fetch the gloves from the storeroom over here. Stay exactly like this, or you're in big trouble."

Abby didn't dare move a muscle, even when she didn't hear the teacher's footsteps anymore. She couldn't risk looking over her shoulder and him interpreting it as defiance. Though the longer she didn't hear him, the more worried she got. Of course she dreaded the invasive and humiliating search, but she dreaded the bell more!

Then it rang.
"No, no, no, no...", she whispered, panic rising as she heard doors open and an increasing number of footsteps accompanied by idle chatter fill the silence of the hallway. Shortly after, exclamations of surprise. Appreciative whistles. Students coming closer. Abby's face felt as if she was burning up. How many were staring at her formerly private parts now?!

Before any of them could get handsy, another pair of footsteps, quick and resolute, approached her. It was the teacher, who was about make her humiliation even worse.

"Make space! I'm administering a cavity search."

"What? Holy shit. Like, your fingers up her pussy?"
"Her ass, too! I guess that's what the lube is for."
"Gotta get this on video..."

That last line made Abby's eyes go wide. They all had phones, and were probably taking pictures already! And now someone wanted to film her getting fingered by a teacher!

"Please, can't we do this somewhere private...?"

But he ignored her. Instead of an answer, she felt him spread her cheeks and put cold lube on her exposed anus, before pushing a gloved finger inside. Abby couldn't suppress a pained moan as the finger slowly overcame the resistance and invaded her body. It felt uncomfortable, weird, wrong. Worst of all, she knew exactly that people could see it all, and depending on where that video ended up, the audience could become much, much larger.

As the teacher searched around inside of her, Abby let out a series of eeps and oohs, until finally he took his finger out, which to her shame was accompanied with a small surge of pleasure.

It wasn't over, though. She heard a new glove being snapped on.
"Hm, I don't think I need any more lube", the teacher said. Abby learned exactly why when he spread her labia open and pushed two gloved fingers inside her vagina with little effort, accompanied by a very wet sound. She hadn't even noticed she was that aroused! That's probably why everyone was giggling so much and there was so little sympathy. They all thought she got off on this!

They weren't exactly wrong, though. The moans Abby let out as her vaginal cavity was being searched could only be interpreted as lustful. When the teacher was done, she could feel herself dripping onto the floor.

"Hm... seems all clean. But I'll keep an eye on you."
