From Pokémon training to baby training
 

Luna was the newest gym leader of Twinleaf city and she was the final test for trainers before the Pokémon league. Her Pokémon were different types but they were all female and were all species known for being strong and motherly. One of her favorite things was tricking smug and lazy Pokémon trainers into betting away their freedom and humiliating them by babying them. She only let them go once one of their Pokémon were trained as caretakers and they were fully diaper dependent

Charlie, however, had no idea about this, moving into the gym with his underleveled team.

"Who's in charge?" He asked, looking around, "I wanna get this over with."

Luna walked into the arena with her Gardivoir. I don't think you should have a attitude towards me in my gym

"I'll have whatever attitude, whenever I want," He smirked, letting out a Grovyle, "Now, do your worst!"

Violating a ton of codes, he had his pokemon ambush the gardevoir before the battle even started.

The gardivoir picked it up with psychic and started to fire shadow ball. You just broke so many rules and in my gym you will be so punished if you lose

"NOOO!!!" He exclaimed, as the fainting was almost instant. He reached for another pokeball, but had left all of them back at the pc... "Fine, you win, but I'll be back for a rematch!"

The gardivoir locked the exits and picked him up with psychic. Oh no you don't. You broke a lot of rules right there and you are going to be punished for them.

"Punished!?" He said, looking at her confused, as he was lifted up, "What do you mean by that?"

She brought him to a huge nursery and laid him down on the changing table." For every rule you broke by pokemon league laws you have to do what ever I say until your punishment runs out or lose your pokemon and license for good."

"What the... why is there a nursery in a gym!?" He exclaimed, as he was laid down on the table, "Fine, I don't wanna lose my liscence."
