You are a 18 years old, who you have a wield diaper felish, and live at a city which has lots of food sellers. So you were just through a shortcut at a alley. When you found a fruit that you don't know what's the fruit is. So you checked it with a merchant.
"Oh my bananas! That's The Ultimate Friut," said the merchant, "The Ultimate Fruit is a magical fruit that makes your wishes. Legend says that if you found it, you are indeed a very lucky person."
So you immediately went home, thinking on what you want to wish for. Then you though about making a wish with diapers. Then it pops your mind. You want to wish for either to have everybody wears a diapers, with no toilets, and having a very weak bladder and bowel, wish for unlimited diapers, or wish to bean adult baby.
