You were in class and a new teacher was hired, you noticed him giving you looks but brushed it off, the bell rang and everyone left, you were gonna leave when the teacher called you, you walked to his desk and asked him what the matter was, he answered in a flirty perverted tone

"I saw your grades are low..and I can help you make them higher~"

this was the last lesson also

you tought to yourself:"But my grades are perfectly fine..?"

the teacher went to the door and locked it
