"I can't believe it, he really said yes to a date. N-Not that there's a lot of places that we can go right now with that Virus going around, but... H-He said yes..."

A shy young lady, Hana, trembled as she slowly made her way towards the place she and her crush had agreed upon. Then, the two of them were going to enjoy as much of each other as they could.

At least that's how Takeshi had said things would go. And since he was such an honest guy, always living up to what he promised, how could she imagine that it was any different?

Not only that, but she really was well and truly shocked over how he said yes to her date proposal. Like, she's nothing special. Mostly flat chest, no real hips to speak of, and she always tried to stay out of sight and out of mind. She didn't even hear any rumors about her at school, all because of how much she isolated herself.

So to have him actually say yes...

"J-Just... Just wish that it was at any other time..."

Hana glanced around as she tightened the mask around her face. She didn't want to catch the virus that had been going around. Especially as she saw some of the infected just waddling around in the street...

The FAB Virus. Fat Adult Baby. It perfectly described what she was seeing. Huge girls with couch-sized tummies just waddling down the street without a care. Wearing t-shirts that perfectly encapsulated what they were into, and diapers that were fuming with filth from how quickly they had been filled and how infrequently they got changed...

While she wouldn't admit it, Hana was glad that a lot of the hotter girls at school had gotten infected. That meant that she had a chance to actually go on this date. A-And the fact that those girls ended up geeky dorks that did their best to play games together made her feel better about this. As long as they stayed out of her way, and still remained happy, there was nothing for her to worry about...

...

"N-No. No, Hana, don't think about the what-ifs. Takeshi isn't going to have to take care of a FAB himself. He's going to be right there, waiting for you in the park..."

The stray thought that crossed her mind was... W-Well, what if she was the one that ended up infected? What would he think then? Would Daddy play ball with his newfound FAB? Would he tease her and just abandon her?

None of those thoughts were anywhere close to pleasant. So Hana did her best to shake them out of her mind as she made her way into the park. She just had to keep her mind off this stuff, and everything would work out.

Not that it was easy to do so. There were a ton of picnics set up in the park, and plenty of babies that were currently busy stuffing their fat faces full of sloppy food.  Food that gradually started to make her tummy grumble and rumble as if she wanted a bite.

She had to resist. If she started to give into this primal need for food, the virus would infect her too. And she'd end up a portly pamper-packer. That wasn't what she was about. E-Even if...

"Ahhh... Goodness, why does my mind have to be this filthy..." Hana lamented, as the thought of bloating out into a big baby crossed her mind. If any of this had been fiction, maybe she would've enjoyed it as a concept. She was a pervert, something she absolutely wanted nobody to know before the time was ripe. Especially if they then found out this did arouse her on some level...

"Oho! If it isn't Hana! Takeshi's been waiting for you, dear!"

Thankfully, even if the sound of those words wormed another blush onto the black-haired perverted girl's cheeks, somebody had recognized her. And that somebody was with Takeshi, another boon even if she didn't want to share a date like that...

She glanced towards the source of the voice, only for her heart to immediately slam deep into the pits of her stomach. Because while the person that accompanied Takeshi wasn't exactly a problem, since she could immediately recognize her as the Mother of her crush...

"Hwanah!"

The state of her crush was something else entirely. Gone was the sporty boy that she had come to crush on for his honesty, his reliable nature, and the way he refused to treat anybody unfairly just because of rumors. The perfect friendmaker, and the one she hoped to go the next step with...

Instead, she found another big FAB sitting on the big blanket that had been laid out. Which honestly looked more like one big diaper, even with the many foods that were cushioned by the crinkly garment. Foods that he had...

No. There's no way that Hana could reasonably call her crush a He any longer. Her formerly short red bed of hair had not only grown longer, to the point where her hair had been fitted into a pair of cutesy childish pigtails, but the red hues had turned a dirty yet bright blonde too. Which only served to heavily contrast the huge nerdy glasses that had been fogged up so badly it was a wonder she could even see her, as well as the big braces that didn't do much except enhance the nerdy aesthetic...

Her chest, which had previously been flat and fit due to the life that Takeshi lived, had transformed into two flabby mountains that were resting on top of her belly to support their weight. All while being wrapped in a 'BIMBABY NERD' t-shirt that was far, far too short for the size of her mounds, resulting in the bottom of it just barely not covering up those big milky nipples that were just begging to be played with. Even if there was no telling what would leak if they got even a little squeeze...

And the rest of her body? Gone was all that fitness that made Takeshi ready to carry Haan if she ever needed to be swept off her feet or otherwise feel like a princess. And in its place, one big ball of flabby, saggy, and extra oily fat. A big flabby baby belly that looked like it could fill up an entire couch, with some cutesy magical girl printed right in the middle. A big, humiliating tattoo that served to tie the rest of her look together, especially with all the sweat and grease that was rolling down it. She didn't even try to look held together, just letting her newfound childish and girly interests consume her completely...

FFRRRRLLLRRTTTT

Something that was all too apparent as Hana's crush giggled and grunted right as she let out a big bubbly burst of gas, drooling as the back of her very browned yet clearly patterned diaper started to push out even further. She even wore a diaper with the same sort of magical girl print as the tattoo on her tummy, which might even contribute to why she refused to get a change when that diaper was almost as big as she was, and it was only going to get bigger...

"Ehehehehehe..." And all she did following that big explosion in her diaper, was giggle and drool more. Like Hana had completely left what little vacancy remained inside of her childish mind.

"W-What happened to Takeshi..?"

Takeshi's Mama smiled as she patted her sweet little baby angel on the head, causing another bubbly burst to echo forth and the load inside her diaper to push out ever slightly further. "Well, Hana, I'm sure you and Takeshi would make a great pair together. You're a sweet girl. You don't want him just for his looks. But I just couldn't let him leave the nest just yet. He still needs Mama's protection. And what better way to keep him protected than to make sure he never grows up?"

Hana couldn't believe what she was hearing. Much as she couldn't believe that she found herself sitting on the very same makeshift picnic blanket, blushing as she looked down at her hand.

While she had been distracted by taking all of Takeshi's changes in, she had unknowingly ended up following the same sort of path that he had taken. That had to be why her hand was covered in such a thick layer of strawberry jam. Why it was just begging her to slurp it all off...

If she did indulge like this, remove her mask and pig out, it wouldn't be long before she'd end up just like him. One big fat flabby baby who wouldn't know any better. A big stinky baby who always just lived life according to what she wanted. Whether that was food or anything else...

Hana's mask started to grow wetter and wetter as she couldn't stop herself from drooling. She had such a difficult choice ahead of her. Not just in regards to leaving Takeshi behind to save herself or just staying here and being with him still, but also what she would do with Mama if she did try to run...

None of those thoughts ended up going very far. Not just because she mashed her jam-covered palm up against her mask, causing her eyes to roll into the back of her head from how good it smelled, but because there was one thing that remained true despite everything.

She hadn't fallen for Takeshi just for his looks or for the way he acted. No. She had fallen in love with Takeshi as a whole. And if he had turned into this big baby, then that was just going to have to be the Takeshi she loved...

And the best way to love him would be to become a big baby..!

"Takeshi... Takeshiiiii..." Hana muttered in an almost delirious fashion as she pulled her mask down, and immediately started to suck the jam off her fingers. Every slurp immediately fueling her body's infection...

Mama watched with glee as her dearest Takeshi's would-be girlfriend gave in. Ahhh, she was already starting to bloat up, the way that her tummy was rumbling and grumbling. And her clothes were changing too, all thanks to the extra doses of the virus that she had snuck into the food...

Hana's messy hair turned the same shade of bright yet dirty blonde as the baby she adored, all while the same sort of thick rimmed glasses slapped their way onto her face. Not that she could really see through them, as the glass quickly fogged up and left her practically blind...

Not that she needed to see her transformation. As she could definitely feel her modest chest rapidly filling up with something thick and unmentionable. Something that made her nipples pop free from their little inverted pocket, drooling that wicked substance as her brand new and horrendously pink 'BIMBABY NERD' shirt did a terrible job giving her any kind of modesty.

The nerdy look up above and the nerdy shirt that broadcasted it all to the world was formally completed as her belly gained the same type of tattoo as the one Takeshi had. It just depicted the magical girl's lover, a former rival turned into something more. And it would be impossible to miss the tattoo, given how much the flab pushed out. How much it weighed down on her knees as it grew past them, making it almost impossible to stand up and use her legs in the first place...

Not that she'd need to walk around at all. Much less crawl. Because the Magical Girl diaper around her waist, which was currently still nice and clean and mostly white, would keep her snug and secure no matter how much she managed to fill it.

FRRRRRLLL- BRRRRRRRRTTTT

Especially once the brassy orchestra that was her guts started to fire up. Fart after fart, messy shart after messy shart. All of it just kept on pouring out without an end in sight. And it was all accompanied by the most obvious and most babyish element of all...

The sludgy mess that she would call 'Poopy' if she became aware. Mushy rope after mushy rope pushing out from that hole over and over, filling up the back of that stinky seat as it gradually grew bigger and bigger. Even faster than she grew fatter, ensuring that she wouldn't be getting up at any point...

Not that Hana cared. She couldn't do much right now even, all she could do was simply eat away and stare forward at her Takeshi. Her babyish partner, who stared right at her too. All while eating more and more, since it was almost like there was an endless supply of food for them...

All while their dear Mama watched them both. Giggling behind her own mask, as she could feel her own tummy start to rumble. Would there be any harm in joining these two lovebirds..?

Whether or not she joined them, the fact remained that she had kept her dear Takeshi nice and safe. And now that she had a girlfriend that matched her...

Ehe. What an adorable life of pure childish excess they'd enjoy...
