I have called Sophia to my office as I need her to run some more special Head Girl errands. As she waits outside my office she is in little doubt the tasks I have for her will involve either being naked or changing into some else. So she casually starts to slip off her uniform, starting with her blazer, shirt & tie. She wonders what I might have in store for her as she slips off her skirt. Still deep in thought she strokes her soft pattered tights before slipping off her heels, then her sexy tights and finally her panties, then, completely naked; she waits for me to call her in.
