This mistress does not like perverts. She punishes and humiliates them for fun and that is what she did to this loser today. The mistress used her bare feet to do it. She crushed a banana and she made a mess on the floor and on her feet. She then asked him to lick the banana from her bare feet as well as from the floor. And from the look on her face, he knew it was not optional.
Mistress Nata did not like how slow this student was. He was making her take a lot of time on one subject and he was, as a result, dragging the entire class behind. The mistress had to find a way to make him work harder and be at the level of the rest of the class. That way, learning would be faster for everyone. She got him to do that by humiliating him with dirty feet a few times a week until he changed.
