"Do you want to do it?" Krillin asked his wife, 18.
"I don’t know, I’ve never done it before," 18 replied.
"Alright, then I’ll go."
Krillin stepped forward, past his wife, as she held their young daughter Marron in her arms. In front of them were the seven dragonballs.
"I summon up the Dragon... I command you now! Hear my howl... to make my wish COME TRUE!"
The balls began to glow and the sky turned black. An instant later the massive form of Shenron emerged from the glowing balls and thrust upwards into the sky. Soon the impressive dragon looked down on the trio.
"I am the eternal dragon! Make your wish and it shall be granted!"
"Big dwagon!" Marron shouted.
Krillin cleared his throat. "Okay, Shenron, I want to wish- Boy, this one is kind of embarrassing."
"More embarrassing than wishing for panties?" Shenron boomed.
"You summoned the dragon to wish for panties?" 18 asked incredulously.
"Oolong did. It was a long time ago. Our first wish actually. Kind of a long story. Not that I was there for it."
"Make your wish," Shrenron said again.
"Mommy, can I make the wish?" Marron asked.
18 hesitated and looked at her husband. "Well, she is the one we’re doing this for," Krillin said.
18 nodded and put her daughter down. "Okay, honey, ask Mr. Shenron."
"Kay," Marron said, then toddled towards the dragon. "Hi, Mr. Dragon," she said, addressing Shenron.
"Greetings," Shenron said cordially. "Speak your wish and it shall be granted."
Marron lifted up her red skirt to expose her plastic panties. They were bulging quite extensively, clearly showing she wore something thick underneath. "I’m still in diapers. Mommy and daddy want to potty train me, cuz they don’t want to change diapers any more."
"So many diapers," 18 muttered.
"But potty training is hard. I never know when I have to go, and can't make it to the potty on time." Marron felt her diaper. "I'm pretty sure I had a weewee just now, and I couldn't tell until I was already going pee in my diaper." Marron let her skirt fall down. "Anyway, mommy and daddy want to wish that I was potty trained."
Krillin let out a sigh. "Finally, we won't have to change diapers all the time."
"The thing is, I like wearing diapers. In fact, I wish that everyone in the whole world wore diapers all the time and no one ever got potty trained."
"Wait, what?!" Krillin exclaimed.
"Your wish shall be granted!" The dragon boomed.
"Wait, stop! Shenron!" Krillin cried out, but it was too late. In an instant the orange gi he wore vanished and was replaced with new clothes. His blue undershirt remained, but now he had on no pants and wore an orange diaper cover with snaps on the front. On the back of the cover the symbol showing he trained under Master Roshi covered his butt. Krillin reached down and felt himself. It was clear right away that he was wearing a thick diaper underneath the orange cover.
18 didn’t fair any better. Her top remained, but her jeans were replaced with a denim skirt. Lifting up the skirt, 18 revealed the disposable diaper she now wore underneath.
"Your wish has been granted! Thus, I shall now depart." Shenron vanished back into the dragonballs, which rose up into the sky and flew off in seven different directions.
"Krillin," 18 whispered.
"I know, I’m wearing one too."
Marron came skipping back to her parents.
"Marron, why did you do that?" 18 asked.
"I don’t want to be potty trained," she started. "Diapers are way better."
Krillin spoke next. "Wait, so those accidents you’ve been having…"
"Some of them were on purposes."
18 was quite mad. "Marron, do you know what you’ve done?"
"I made it so no one will ever have to use the nasty potty again!"
"Some of us liked using the potty!" 18 snapped.
"18, I don’t think Marron realizes that what she did was wrong."
"So you don’t want to punish her, even after she did this to us?" 18 gestured to her diaper.
"First, we’ve got to make her understand that her wish was a mistake."
18 grit her teeth. This was a new feeling for her. Not the diaper. Well, that was a new feeling, but she had never been upset at her daughter before. Not really. But now…
"We’ve got to find a way to fix this," Krillin said. "Maybe Bulma can help. Or we could ask Majin Bu to use some of his magic. We’ve got to-" Kirllin noticed Marron was hunched over. "Honey what are you doing?"
"Poopy!" Marron said happily. A second later her plastic panties bulged out in the back, her diaper now holding a stinky mess.
"Great," Krillin said.
"If we don’t do something fast, we could be the ones filling our pants," 18 said.
"Right," Krillin nodded. "Now, what do we do?"
