Ms. Lustby was by no means an ugly woman, but she was considerably older than the rest of the class, so wasn't normally considered in the school-wide functions. Her hair was long, dark brown, and luscious and her figure was stunning. Jon would have very much liked to get her to take her top off.
Jon walked slowly up to the front of the class and waited beside Ms. Lustby's desk.
"As you know," she began, speaking to the whole class. "I also have the abilities to change myself. But I also have the ability to change you students as an tool of encouragement...or punishment."
She glanced at Jon. "So far this year, I have not yet had the opportunity to use this ability in the form of a punishment. You are indeed a well-behaved class. But now one of you has slipped up, walked off the path of the straight and narrow, and now Jon, I will use you as a warning for the other students, lest they may decide to follow in your... footsteps."
"Jon," she began, turning to him and speaking only to him. "Please drop your pants and undergarments."
Jon hesitated only slightly, but didn't want to get in any more trouble. When Ms. Lustby also began undoing her own pant buttons, his now-free dick began to harden at the thought.
"No Jon, that is not what I had in mind," said Ms. Lustby. She dropped her pants to reveal beautifully sculpted legs...and a monstrous cock that put Jon's to shame.
