Tina couldn't bring herself to turn Leah back to normal so fast. The girl was just too cute as a pants filler! And, given how little distress she seemed to have, Tina wondered if this was something Leah secretly wanted.
After a few minutes of thought, Tina decided to give it a week. One week of Leah being diaper dependent would be enough to satisfy Tina, and would give Leah a chance to explore how she felt.
Leah returned from the shower. Tina diapered her. Leah sighed.
"If this keeps up, I might have to learn how to diaper myself," she said. Tina smiled.
"I'll gladly teach you."
"...Thanks."
During the night, Leah pooped in her sleep. Tina still obliged to her request in the morning and let her wear training pants while awake. She found Leah in a secluded corner a few hours later, grunting as she emptied her breakfast into her training pants.
From then on, it was diapers 24/7. Tina agreed to teach Leah to change her diapers, which she was glad about. Knowing she didn't have to deal with the diapers being dirtied made the fact that Leah was dirtying them even cuter to Tina.
Soon, the week was up. Tina sadly reversed the command, putting Leah back to normal. At least, that was what she thought.
