What kind of girl or what kind of torture you can use to make her smile ?
LOL
Torture is not gonna improve her signing or dancing.


But in that situation I woud use some relatively mild torture methods that leave no damage and no long lasting pain.

So I woud will her with enema and make her wear butt plug.

I woud putt catheter in her pee hole and not let her pee until she finishes her lesson.

I woud stick needles in her breasts as punishment for making mistakes.


also I woud make her perform naked with her student name tag attached to her nipple and also make her wear high heel shoes.

when she is dancing and if she makes A mistake I may throw a dart at her
