Welcome to Expansion 101.  Here you will learn how to grow and shrink any part of your body.  And I do mean anything.  Now class is about to. . . wait I think we might have a problem.  (This story is only on my Patreon all-access tier.)

Gloria walked into the classroom, her boobs bouncing against one another. “So, I see we have quite a few young and fresh faces in here today.” She looked out across the room. “I will be your teacher for this semester. My name is Gloria, and this is Expansion 101.” She turned around, her shorts barely containing her massive rear end. “Don’t let the name fool you as we cover all manner of size altering here. You will learn how to control altering the size of every part of your body when we are done here.”

             She turned her head as she heard giggling. “Is something funny?”

             One of the young ladies shook her head, her long blonde hair bouncing against her shoulders. “No. Not at all.” She put her hands behind her back.

             Gloria sighed. “Now I know this isn’t a conventional class, but. . .” She arched an eyebrow. “Hey, where is my spell book?” She put her hands on her hips. “I could have sworn I put it somewhere.” She began to dig through her desk, showing off even more of her butt to the class. “Now, where is it?”

             The blonde girl giggled. “I have no idea, teach.”

             Gloria snorted as she stood up. “Well, we can’t start without that spell book. I know it’s funny to hide the book on the first day of school, but. . .” She moaned as her boobs began to swell. “Fuck.” She looked down at her chest as her blouse pressed tightly against her chest, her breasts bursting out from the seams of her outfit. “Ok, which one of you jokers has my book.” She looked around at the class. “Well?”
