Yes

"I mean" you lick your lips seductively "that you could test my oral skills...while I'll be in a kneeling position."

"So" he smiles "if I understand you correctly, you offer me a sexual gratification in exchange for improving your grades."

"Well, yes" there is no way around this "I think that's a fair trade."

"I'm glad that you made it clear. Do you want to go to the principal office immediately, or do you prefer to look at your test?"

"Wait, what?" oh fuck, fuck, fuck!

"Offering sexual services in exchange for grades is a pretty big offense miss Roden, I'm sure that you are aware of that?"

"But, don't you think I'm attractive?"

"Of course I do" he smiles. This time it is a smile of a predator, who almost caught his prey "but I also know that you are recording this conversation. Which is another violation of school rules."

"I...I..." you don't know what to say, he outplayed you completely.

"Now, you have two choices, Emily" this time he uses your first name "you can either hand me your phone and then we will discuss your situation. Or we can go to the principal office."

That's not a real choice, you both know that. You give him your phone. You assume that he stops the recording. Then, to your surprise he stands up and closes the door to the classroom.

"Now we can speak freely. But just to be clear. I've got this recording on my phone. I can still go with it to the principal."

Fuck! You were supposed to be a blackmailer, not the victim!

"Please don't do that, sir" you say while looking at the floor.

"Look at me Emily" he says "I think we can come to an agreement. Get naked."

"What? No!"

"As you wish. I guess it's time to go..."

"I'll do it. But why?" right now you are just stalling, waiting for miracle to happen. You know very well what he wants.

"You know why Emily" he stares at your boobs openly "But I will explain everything in details once you are naked."

He **** you into a corner. You swear ****, but you know that right now you can't do anything. Your hands are shaking, so undressing takes more time than it should, but your teacher is silent, he quietly observes you. When you are finally naked, you try to cover you breasts and pussy with your hands, but he orders:

"Put your hands behind your back. And face me."

Again, you have ****, you do as he wants and present yourself to him. He stands up and walks closer to you. "Very nice" he says while touching your breasts briefly "so, now time for an explanation."
