Knowing that she wanted to torture her tiny brother, Naomi decided that she would have to make Jiro suffer a little bit. But how? Then, an idea came to her.
"You just sit tight, there, bro," she said. "I'll be back in a little while." Then, to Yukiko, she said, "Watch him until I come back."
Naomi ran off to the bathroom and quickly cleaned herself up and then got dressed. When she returned to Jiro's room, she found the tiny boy still standing on his bed, looking very worried.
"Hello again, Jiro," she said. "Did you miss me?"
"Please turn me back, sis." he said. "I promise I'll be good from now on. Really."
Naomi just smiled and looked over at Yukiko. It was time to put her plan for Jiro's punishment into action.
"Yukiko," she said to the fairy. "You know what Jiro used to do? He used to take all of my underwear and hide it, just to mess with me."
"Did he really?" asked Yukiko. Naomi and the fairy looked down at the 4" tall 10 year old and smiled. Jiro shivered. What were they going to do to him now? he wondered.
"Since you're so fond of my panties," said Naomi. "I think you might enjoy a ride inside of them."
"What?" piped Jiro.
Naomi reached down a comparatively giant hand and picked him up. His whole body easily fit inside her palm. With her other hand she unzipped her skirt and then pulled open the front of her pink panties.
"Down you go," she said as she slipped her tiny brother down her underwear. He stood there on top of the tangle of her pubes and looked up at her with pleading eyes.
"Don't do this!" he shouted desperately.
"Enjoy the ride," Naomi said as she closed her underwear back up, muffling his final scream of "NOOOoooooo..." She could feel Jiro pressed up against her lower abdomen. He squirmed meekly against her, but it was no use. He was trapped by the elastic fabric of her underwear. She could still hear his muffled little voice faintly pleading to be let free, until she pulled her skirt up again. Now, no one would notice that there was anything in her panties.
Knowing that Jiro could hear her, she said, "I'm going to keep you in there for a little while. So, you might as well get used to it. Hopefully, after this, you'll never want to touch my underwear again."
Although it was hard to tell for sure, Naomi thought that she felt Jiro's shoulders slump when he heard what his fate would be. Naomi just relished the idea of how miserable he must be right then.
She smiled, "Yukiko?"
"Yes?" said the fairy.
"I think we're going to have a lot of fun together."
"That's what I'm here for."
Naomi thought a moment and said, "How about you disappear for a little while? I'm going to go get some breakfast."
"Sure thing," said Yukiko, who instantly vanished. Naomi then headed downstairs, with Jiro still tucked away in her panties. In the kitchen, she found...
