“I’ll go ahead and buy the diapers,” Harry said.
The worker gave him a box of diapers. It was a blue and white box with a child on the side. He had his back turned and was flexing his muscles.
“If there is any other baby thing you want, please ask and I’ll show you the way to it!”
“I think just the diapers are fine, thank you!” Harry carried the box and started looking around for a bathroom. In a place where magical diapers exist, Harry got an idea. He turned back to her, “Where could I test these?”
“Oh, you’ll be testing the spare diapers we have for these situations. That way, you aren’t using diapers from the box.” She led him towards an obvious dressing room, but each door had a few drawers next to them, each labeled. She stopped in front of a door that had boy clothing on the drawers.
”Now go ahead and choose the diaper you want!” she pointed at the bottom drawers.
Harry set down the box and open the bottom drawer. It was filled with baby diapers, all having different designs. He looked in the next drawer above it and found the same diapers that he was buying. He grabbed a pair and walked into the changing room.
As he was stripping down, he could hear the woman suggest something to him, ”When you wear the diaper, think of the age you want to be! There is someone at the register, so please wait for me before you come out!”
Harry heard her footsteps get farther and farther away. ”Think of my age huh?” he thought to himself. He took off his clothes and looked at the diaper. ”Everyone knew that it wouldn't fit, so why should he bother,” he thought to himself. Then he realized, it was a magical diaper. Harry tried to remember how to change a diaper, or at least put one on.
First, he laid on the floor and unfolded the diaper. Next he slid it under his rear and folded the front part of the diaper onto his genitals. After that, he taped the sides together. Finally, he got up and made sure the diaper wasn't too low or high. To his surprise, the diaper stretched out to fit him. ”Think of being two! Think of being two!” he repeated in his head. As he thought of his age, he could feel his body change. His arms and legs felt like he had goosebumps all over. His chest started to tingle. His whole body felt changes.
A few seconds later, Harry saw that the transformation was complete. He had become a toddler again. Suddenly, a familiar feeling ran through his body. The whole reason he wanted to test run the diapers.
Slowly, the front of the diaper was losing its childish design, and was replaced with a yellow stain. Harry could see the process in the mirror as he pissed himself. When he was finished, he felt relieved. He looked at the diaper again, and it was changing back to a clean diaper. Before his eyes, the yellow stain and the warm feeling around his crotch was going away, changing back to the dry feeling of a diaper.
“That was a fast diaper change” Harry said to himself. He was about to take the diaper off until another new feeling came up. His stomach wasn’t feeling alright, which caused him to poop in his diaper. Harry tried to stop it, but his toddler instincts let it happen, and forced him to squat. Slowly, the diaper started to sag.
After an inhuman amount of minutes, Harry stopped dedicating. He was panting and sweating from it, and felt glad that it was over.
He could feel the weight of his diaper being sagged by his poop, and the warmth of it. Once again, the diaper began to clean itself, with Harry along with it. After it finished, Harry didn’t feel any trace of poop or pee on him. He untapped the diaper and looked at his naked toddler self.
“No pee! No poop! I don’t need anyone to change my diapers!” He said to himself. He tapped the diaper back together and opened the door. He was looking for the woman from earlier, but...
