Class gets organized

Greg the geek vanished in a flash, turned into Gina. A girl who never had a run in her pantyhose or was late to class. His friends Liz and Cindy vanished next. Replaced by Elizabeth and Cynthia. Two girls who always made sure their skirts were pressed and pumps were shiny. Every student morphed before the teachers eyes. Soon every one of them was sitting upright in perfectly uniform black tights, black skirts, white blouses, and perfectly trimmed straight haircuts and headbands. She saw her class transform before her eyes replaced by school girls in uniform. And she loved the result.
