Mary picked up the case of vials, confused at why she would receive something like this. She was very open minded, though and had no doubt that these would work. She did have a younger friend working at TG Soda, from goodness sake.
She pressed the button curiously, opening up a plethora of vials, all coming in different shapes and colors. "Wow, this is amazing!" She marvelled, fingering them all.
She thought about which one she wanted, and finally decided on an age vial, which would regress her to a 17 year old, the age of a high school junior.
"Going back to high school should be fun!" Mary said, looking around her house. "Besides, I could get into a college easier now! Passing U.S history will be a breeze!"
Her mind made up, she picked up the vial, a cream colored flavor, and drank it. The changes happened instantly, her body structure regressing to what it used to be. Her breasts downsized from a E-cup to a B-cup, as did other parts of her body.
When she was done, she found herself in ill fitting clothes, back to the age of 17.
"Wow!" She said, twirling her body in wonder. "It feels so good to be 17 again!"
