I also like to think about this topic as a sort of revenge. If there is two parts: The first is a girl who is calm, but gets mocked by another girl. The first girl is getting sick of it, and plans a revenge on the mocker-girl.
In this case, I remember some years ago, a teacher at my high school. She had us in gym and swimming, but also maths. My class didn't like her at all, because she was so...b*tchy. But the teacher, aged about late 20's/early 30's, was a good milf too... She had relatively big breasts, and her butt was every boy's dream in the class.
When we were last-year-students, we wanted to do something bullish to her. One of the ideas (that the stupid girls in my class didn't have the courage to follow through), was this:
In our last swimming-class, the girls would stand like they always did; changing to swimming clothes, like normal. When the teacher arrived, they would greet her as they normally did, and act like nothing were up. Then, when the teacher was changing in the dressing room, they would bust the door open, strip her totally naked, put a towel around her, and carry her up to the main pool - where all the boys would be waiting.
When they would arrive, they would pull the towel off, exposing her full frontal against us, then turn her around, showing her bare ass to the class. At the end, all the girls would push her into the water, and lock the door to the dressing room after all of us had run back down there, and changed to our normal clothes. She would still be in the water, to shameful to come out. How about that for a last swimming-class.....
Oh well. I guess I'll never get to see that in real life, after all. But it was close....
