Yes, patience...

"...you see self-control is very important. And I think that you are lacking it."

Not this bullshit again!

"So we'll work on that. Nobody will have lessons in this classroom today and I need to check the tests of students from the third grade, so I'll do it now. And you will kneel near my desk. And you will suck my..."

Ha! Finally

"...finger."

"What?"

"You will suck my finger" he explains calmly "it will prepare you for the future and also will let you to work on your patience. Because if you stop sucking my finger until I let you even for a moment, the deal is off and principal will hear some interesting recordings."

He doesn't need to say more. You kneel near his desk, he sticks his finger and you obediently take it inside your mouth. You try to make it as sexy as possible, but to your great annoyance, he doesn't even look at you. For fucks sake! You are the hottest girl in the whole school, you are kneeling naked and he is more interested in fucking tests? That's borderline offensive! You are doing your best to pick up his interest, but he behaves like a stone statue. He doesn't move, he doesn't look at you.

Next hour is a ****. You would never think that being blackmailed by a teacher could be so...boring. Your knees are sore, your jaw hurt. You slew down few times, but every time you did it, he raised his eyebrow without looking at you, it gave you incentive enough to keep sucking his finger. When he finally says "I think I'm done" you are grateful. He hands you your phone, "I made sure that you have my number" he said "you did good Emily."

You have no fucking idea what to answer, so you just say:

"Thank you sir."

It seems that it pleases him, because he gives you a small nod. Finally you can leave the classroom. That was...bizarre.
