During lesson

You know how to play this game. In the right moments you send him smiles, or slightly move your feet, or look suggestively straight into his eyes. Few times he stumbled on his words and his fighting very hard no to look at you. It's a losing battle. It's almost pathetic how easy it is for you to control him. This morning you planned to ask him for 4, but now you now that you'll demand the highest grade. He asks for a volunteer to solve some task on the board. You raise your hand. He swallow his saliva and asks you to come forward. You do that knowing that his (and the whole class) eyes would be glued to your backside. You know how to use that. You "accidentally" drop chalk and when trying to pick it up you bend over, showing your teacher your ass.

"Thank you miss Roden" he says after you are finished. Actually the task was surprisingly easy, it's possible that he did it on purpose, hoping that you would volunteer.

He asked two more people to come to the board, but for almost the whole time he's looking at your body. He is making it a little too obvious, but fuck it! You'll get what you want. When the lesson ends you wait for everybody to leave the class, start audio recording on your phone and then attack:

"Professor" you start with sweet voice.
