Allison runs downstairs and sees her mom getting ready for a trip to the store. Allison quickly goes over to the kitchen and gulps down a big glass worth of water, the idea of using her diaper in public with no one suspecting it slightly damps them. Allison hollers at her mom, "Hey Mom, I am ready to go to the store with you!" Allison's mother replied, "Oh nice, you even got something to cover your underwear too. Let's go out shopping."
Allison and her mom walk outside the door, enter the minivan, and the ride starts at the grocery store. The ride was going calm and quiet as the radio was playing music, but Allison was only thinking of one thing, "Did Mom really know it was a diaper? Maybe she just didn't want to question it." Some doubt was still inside her mind about her new light purple garments, and Allison really did not want to make an accident just for the 'magic' not to work and look like a dumbass.
So, with a heightened voice, Allison starts, "Hey mom?" Allison's mom lowers the radio volume so she can listen to Allison directly, "Yes Allison sweetie?" "When we were talking earlier, back in my room, did you notice anything different during that moment," Allison asks. "Oh sweetie, don't think I've never seen a pair of panties before," Allison's mom chuckles, "I mean, it was a little weird to be out of your room only wearing it, but you were just changing pants and you only wanted to talk back to me when I was at your door."
The term 'panties' now satisfied Allison's suspicion, there is no person, let alone a mother in the world, calling a diaper a 'panty.' So Allison replies, "Yeah I was just a little anxious being that bare to my Mom," with an added forced laugh. "Oh sweetie, I'm a girl just like you. A pair of visible panties is not going to make me turn away," Allison's mom replies with a little rubbing motion on Allison's back. While Allison was a little embarrassed about the talk, she at least knew she could mess herself in the diaper whenever she pleased. So the radio volume got turned up and the ride continued quietly until they got to the grocery store.
Allison and her mom got inside the grocery store, grabbed a shopping cart, and started grabbing some groceries Allison's family needed for another week. In the middle of the shopping spree, the water she gulped so fast back at the house was already in her bladder, and she was feeling so full. Allison was so ready to use her diaper but didn't know how to use it while in public like this. She knew that nothing she could do would make anyone suspicious of her magical diaper, so Allison took in a deep breath, squatted down, and pushed on her bladder, filling up her diaper in the process. The feeling of the warmness and mush against her crotch was making her feel so horny, but she knew that the diaper wasn't going to cover her naughty actions in sight. Allison's mom ran back and came up to Allison, asking her, "Hey Allison, are you okay? I saw you squatting and didn't know if you needed to use the bathroom or not."
Other than the irony of that statement her mom just made, Allison did have the choice between changing out of her diaper for another pair she took with her, and maybe adding a new effect on herself, putting on her panties instead and acting like this never happened, or even keep what she is wearing on and continue shopping in a wet used diaper.
