"You truly are adorable when you sleep, you know that, Champion?"

Cynthia's eyes gradually fluttered open as a motherly voice spoke out to her. She couldn't really recognize it... Much like she couldn't really recognize that much at the moment. All that she could recognize was that she felt really heavy... And kinda... cold...

"Who... Who're... My head..." She muttered, all while trying to move. Yet she found that she could not do that. Her arms and her legs were both bound, and the realization that she was bound gradually served to make her aware of what was going on. "What did you do to me..?!"

Hovering ever slightly in front of her was a silver-haired woman with a long braid hanging off her shoulder, a monocle covering up her exposed eye... And breasts that were way bigger than they had any right to be. Breasts that made it impossible to really take a good look at the sweater they were captured inside, or the lab coat that covered up the rest of her body. To the point where a little bit of drool started to roll its way down the Champion's chin as she was almost entranced by those massive matronly mammaries...

Right up until she shook her head again and realized what she was doing. Cynthia struggled against her binds once again, all while getting a good look at herself. Compared to the woman in front of her, she was naked. Well, almost naked. She was wearing a diaper, a diaper that was patterned after Munna...

"I am Professor Makase. But you can call me Mama, most adorable girls like you do after a few procedures. As for what I did to you... What did I do to you indeed?" The monocled matron smiled while introducing herself, and reached gently towards the diapered Champion. All so she could cup Cynthia's cheek, the woman trying her best to pull her head away from her to no avail. "What indeed. Perhaps you'd like to see the results of your procedure, before I give you the summation? It won't take long at all."

Cynthia didn't like the implications of what the clearly deranged Professor was planning, but it's not like she had much that she could do. She could just barely see her Pokéballs, at least the ones she thought were hers, sitting on a counter not far from where she was bound. If only she had installed voice recognition...

"Come in, dear. She's almost ready to be your sister."

The deranged Professor stepped out of the way. All while another woman slowly entered Cynthia's vision. One that she was a lot more familiar with, though the lack of glasses and her much more infantile garb made it hard to think of her as the very same woman...

"Fennel..."

The blue-haired woman currently lumbering towards the big chair where Cynthia was bound was a close friend of Cynthia's. Professor Fennel, whose research was centered around the dreams that Pokémon had. So to see her wearing a Musharna-themed onesie, and an exaggeratedly huge diaper pinned underneath that garb... It filled Cynthia with second-hand embarrassment, and a good deal of empathy on top of that.

"Mama... Play?" Fennel spoke, and in the process revealed the complete lack of teeth in her mouth. Leading to an incredibly difficult to parse lisp, and a good deal of spittle dripping out onto her chin as she reached for her Mama's arm. She felt uncomfortable on her legs, even though she could still use them.

"In just a moment, dear. Mama's making another Baby. Just like she made you one. Remember?"

Fennel slowly nodded, all while Mama ruffled that hair of hers. She simply giggled in turn, as the front of her diaper gradually turned yellow as a faint hissing sound started to echo out...

"You... You turned her into this..? That's what you're going to do to me..?" Cynthia couldn't believe it. She wasn't going to let it happen to her either. No way...

The matronly Professor chuckled. "Oh, you'll end up much worse than her, Champion. Fennel was a mere experiment. An adorable daughter that I'll take care of as her brain remains unable to develop, all thanks to the permanent dream I fitted into her head." Professor Makase said, all while kneeling down slightly and kissing her sweet baby on the cheek, causing Fennel to giggle again from the show of clearly depraved affection.

"I happen to be in a rather forbidden field of study. The connection between Pokémon and Humanity. We need to understand exactly what separates us from them, don't we? That's when I heard of dear Fennel's field, a field that allows Humans to interact with the dreams of Pokémon. And I had a thought. If our dreams are that similar... Why not see what happens if we fill the mind with a dream, especially a Pokémon's dream?"

It all sounded deranged. But given what had happened to Fennel, it wasn't hard to believe as truth...

"So you're going to fill my head with a dream. How do you plan on doing that, you can't just cram it in there." Cynthia said, all while still struggling a little. "You won't get away with this either. The moment they realize I'm away..."

"They won't realize. I've already gotten in contact with a professional Substitute. As far as the world is concerned, Cynthia's just on vacation and will return in a week." Professor Makase said, smiling as she came closer. All while reaching for a mask hanging from the side of the chair Cynthia was bound to. "All while the real Cynthia, or what remains of her, has become a Pokémon. An incredibly infantile Pokémon that looks a little too humanoid, but a Pokémon nonetheless. An incredibly shiny, incredibly stinky, and utterly unrecognizable Pokémon..."

Cynthia was too shook by what was being implied to stop the mask from being forced onto her face, with the contraption locking in place to ensure that she couldn't force it off. And the moment it locked onto her face, it already started to pump a strange gaseous substance into her face...

"Don't even think of trying to avoid breathing it in. It's absorbed through contact with the skin. So enjoy your last few minutes of humanity, dear Champion. Mama will take good care of you from now on."

Cynthia could barely even hear what the Professor was saying at this point. All thanks to how effective the gas was. Her eyes were fluttering between open and closed as she felt all sorts of weird sensations spread through her...

It was like her mind was trying to tear itself apart... No, it wasn't tearing apart... It was drifting apart. Forced apart. As a cloud gradually took its place. Making it harder and harder to think as she gradually stopped struggling, because the mere thought of struggling took too much effort to maintain...

Instead, Cynthia just sat there in the chair. Her eyes dimmed slightly as the gas continued to work its way through her. Making it harder and harder for her to do any single thing, because all of her thoughts were being completely replaced by that cloud. By that 'dream'...

*Hisssss...*

Eventually, it was simply too much for even her subconscious to handle. And the parts of her that her subconscious was in charge of, such as making sure that she didn't wet herself while she was awake, were pushed into the far reaches of her mind.

Leaving the Champion, the peak of Pokémon Trainers... To wet herself. Like a big baby. Like a big baby that had never learned anything. Like a big baby that didn't know a single thing...

All while Mama kept watching. Not that Cynthia could see Mama at this point. Seeing meant that she was using her thoughts. Thoughts weren't allowed inside of her head. All she could do was just sit there and use her diaper...

Fennel watched as well. She could feel a little pang of worry inside her heart as Cynthia started to wet herself. But all it took for her to start giggling again was Mama wrapping her arms around her, and lifting her into her big strong arms...

"There there. How about we go figure out what kind of Pokémon she should become? I'm sure you have lots of files on that big computer of yours. Files I need to erase once I'm done here. Because my sweet little Fennel was never a big Professor, was she?" Professor Makase said, and Fennel simply giggled in turn. Unable to fight back against her Mama, because of the dream of love that had been forced into her head. The love that left her a giggly baby that loved her Mama and nothing else...

Cynthia was left in the chair as both the regressed and the repulsive Professor left the room. All while the mask gradually opened slightly. All so it could allow for a few arms to reach towards her mouth. A mouth that was growing softer and softer as the gas sank into her...

She wasn't a human any longer. At least, she wasn't meant to be. And the chair, specially tuned to ensure the illusion was kept, was going to make her look the part. Partly by dealing with her teeth and leaving her with nothing inside that mouth of hers, since she wasn't going to be eating anything except for the mushiest of poffins...

And partly by dealing with that big mane of blonde hair. The sound of scissors snipping away at her hair echoed out, but Cynthia did not react. Nor did she react to the sight of hair falling around her...

Her mind was numbed by the process. She couldn't do anything. She didn't know anything. As far as she was concerned, she just was...

And even that was in contention, as a gasp left her now-toothless mouth. And the brief *Plbrblt* sound that echoed out from under her, wet and disgusting as it was, only served to emphasize what little remained of her.

She had soiled her diaper. Filled it to the brim with what remained of her mind. All of it converted into nothing but a brown stain in the back of her diaper. Ensuring that she wouldn't recover...

Ensuring that she would make such a cute and obedient Pokémon...

"Woohy! Way!"

Fennel giggled as threw a stick. It wasn't a very good throw at all, because her motor skills weren't that developed. And the extra puffy, extra shiny dress that Mama had put her in, with all those frills that made her impossible to ignore? They definitely didn't help matters either.

But she threw her stick. And her adorable little Poochyena, or 'Woohy' as the toothless baby was barely able to babble, barked and chased it down...

Though Woohy was no ordinary Poochyena. Even if many people definitely recognized her as one. She had the same colors, and the rough stance of one. But she was way bigger than one, and there were those big breasts that hung from her chest. Not to mention that her fur looked a lot shinier, like it was latex...

And the stink that almost always wafted from her butt, spread around by the way that she eagerly wagged her tail like the eager puppy that she was, definitely didn't help matters either. Neither did that extra puffiness around her waist, but since she looked like a Poochyena at a glance, and stood like one, and acted like one? It didn't matter that she basically just looked like a human woman in a latex fursuit with a diaper wrapped around her waist. She looked accurate enough.

Which was why nobody bothered to look closely as she wrapped her toothless mouth around the stick that her 'Waina' had thrown, and quickly ran on all fours back towards her. Lifting her stinky butt up into the air and slamming it back down as she sat in front of Fennel, happy and proud to have caught the stick and brought it back.

"Oo Woohy!" Fennel giggled and hugged the latex Pokémon, not able to distinguish it from the real thing. Because Woohy was hers! Her favorite Pokémon! Mama helped her catch her, and she loved her lots and lots!

So lots that she grunted almost at the same time as Woohy, with the stink around them only growing as both of them ended up filling up their diapers more than they already were...

All while their Mama watched from a distance. Professor Makase grinning as she had replaced her monocle with a pair of shades, and her lab coat with a fur coat that made her look like the rich woman she was at heart. The rich woman that was conducting awful experiments on famous people that needed to be so much more adorable...

She had turned a Professor into a sissy baby, and a Champion into a latex Pokémon. And that was just the tip of the iceberg. So many adorable girls that needed to leave their lives in her hands...

So many dreams that needed to come true...
