You left your phone and your teacher found it. She also found the photos that you have been taking of her and the other teachers legs... So this is why your grades are slipping, you cant focus with your mind on your fetish. She tells you to stroke it right there in front of her to help get it out of your system. If this continues to be an issue she threatens to not only tell your parents but make sure that she and all the other female staff start wearing pants! She only wants the best for you and your future.
