Harry decided to test out the pull-ups. The woman serving him led him over to a few change rooms, and gestured for him to go in one, handing him a test pull-up with a Cars design on the front.
“Now, when you put this on you just have to think of the age you want to be. Anywhere between two and six years old will work for sure — you can try to be older, but the results cannot be guaranteed.”
Harry held the pull-up between his hands and squished it lightly, hearing the crinkle. He closed the curtain behind him, waving shyly to the attendant, and set the pull-up down on a provided table.
It took him a minute, but he finally started to take off his clothes, shucking the pants and underwear to the side before stripping off his shirt, and then bringing the pull-up in front of him.
Now he just had to decide what age to become.
