I was in high school and a teacher, Mrs. Z. liked to sit on a stool at the front of the class and lecture at a pedestal podium. One day she wore a skirt without stockings that was only up to the top of her knees. I was sitting about three seats from the front and to the side and laid my head down hoping to get an upskirt view. I pretty much expected to see white panties, but much to my surprise I was gifted with a full 70s bush. Many tissues were used in the weeks to follow.
