[Americanization, Bimbofication]

"I am pleased to see you here, Atsuhi. I would have imagined that you would turn this request down, given the current state of your relationship with Senpai."

"You don't have to call me that, Yuuka. Let's just set that straight. As for Senpai..."

Momiji's hair started to flicker with flames as she stepped into the empty classroom, her anger starting to burn brightly. All thanks to the brazen offer that she had been sent by her icy 'friend'. "YOU THINK YOU CAN TAKE HIM? YOU REALLY THINK YOU CAN JUST WALTZ UP AND TAKE HIM FROM ME?"

"Yes." The icy-haired girl replied, not bothered in the slightest by the inferno that was starting to pour forth from her friend

And there went the flames. Yuuka's deadpan way of reacting to the world made it impossible to truly read her. Which led to instances like this where she simply deflected such pure violent emotion and snuffed it out with a single word.

"Fine. Alright. Okay. I don't see how you'll do that, but I'm willing to listen." Momiji muttered, not happy with the girl trying to be a rival. "You said you had gotten advice from Yuuki-senpai, your big sister? What did she suggest?"

Yuuka nodded as she motioned towards the table behind her. "I asked Yuuki-nee what she would suggest to use to, and I quote her words here, 'charm Tsubasa's pants off'. And she gave me this in response. Though I do not quite understand where she would get these from."

Momiji stepped closer, only to immediately turn bright red at the sight of the garment that was laying on the surface of that table. Laying right there were a matching pair of HUGE American flag bikinis. The kind that was even bigger than the one she had seen that Bison lady wear. The kind that you needed like, huge doorstopper-tier tits to wear, and if you had those... Then the bottom was just going to get swallowed by your ass because...

She shook her head as she tried to compose herself in the face of these bikinis. "You can't be serious, Yuuka! Not only don't I think that Senpai will actually like us if we wear this, since he's the type to like us for who we are, but we can't even fit them on! They're too big!"

Yuuka nodded, as she picked up the huge bikini top and put her face up against one of the cups. A cup that covered up her entire face, before pulling it back and nodding slightly. "It is indeed too large." She commented dryly, before carefully letting it hang close to her chest. "However. This will absolutely work on Senpai. He is weak to this. Weak to many things, at that."

Okay. Momiji didn't really have an argument there. Tsubasa was... Well, he was a very nice boy, and he knew a lot, and she really did treasure him and how he felt towards her. But... Yeah. Yeah, he was a pervert at the core, and he would definitely be knocked straight into next week by a pair of fat American tits...

"So what if he'll be beat by these? We don't have the tits that can help us actually fill these out, Yuuka." Momiji muttered, not exactly happy with her lack of a bust. It wasn't that she was flat, she had some small breasts. But they definitely paled in comparison to what would be needed to fill these out...

Yuuka didn't seem too bothered by this physical constraint. If anything, she wanted to see if it was truly going to be a problem. And what better way to find out than to strip down then and there, letting all of her clothes hit the floor just like that?

"DON'T JUST CHANGE RIGHT IN FRONT OF ME!"

Momiji's protests went unheard, as the pale-skinned Yukionna simply stood there. Bare as could be. Not just by having her clothes completely removed from her body, but she had shaved all of the unnecessary hair away as well. Leaving her with a pure body unlike many others. Including her fiery friend...

She wouldn't stay naked for long, however. She began putting on the bikini top, letting it hang and sway without any breasts to fill it out, all while reaching for the bottom and slipping it on with remarkable ease, barring the fact that she had to keep hold of the bottom to ensure that it didn't fall down to her knees.

"Hm." Yuuka muttered as she held the top with one hand, and the bottom with the other. She needed to find a way to handle this. Otherwise, she wouldn't be able to accomplish what her Sister had told her to do. And she really did want to make it work. Yuuki's advice was worth everything, given all the cool things that Yuuki had done all on her own.

If Yuuki said that this bikini was going to make her able to seduce Tsubasa, then she was going to make it work. Somehow. Not that she knew how, just that she knew that she needed to make it work.

Momiji did her best to keep her eyes away from Yuuka, so that she didn't look at her friend nakedly standing there. It wasn't that she was repulsed by her body, but more so that the only time they should be looking at each other while naked was before Gym! Come on, why did she have to be so weird about it...

"Fine, whatever, I'll try it too! And then we'll be titless together!" She huffed. She couldn't allow Yuuka to go humiliate herself in front of Senpai. That wouldn't be right. He was a caring and trusting boy. And as much as she knew that he loved her, she didn't want her supposed rival to sink to the bottom of Senpai's rankings. Not that she knew what exactly Senpai's rankings were like, but it was the thought that mattered more so than anything else!

Before long, the two rivals stood there. Both not even close to really wearing the bikinis. They simply did not fit. And yet there they stood. Momiji backing up her rival despite how stupid this whole idea was.

"Okay, so how's this going to wooorrrKKKKKKK-"

Right as Momiji was about to complain, the sound of a firework going off echoed through both girls' ears. A loud and potent sound that reflected the equally powerful change that was slamming through them at the very same time.

The top that was just kinda hanging around their necks? Immediately filled out by a pair of extra fat udders that actually started to strain away at the top. They went from being small-breasted to filling out their tops like they were a pair of bimbos that had gotten their tits expanded to a degree that wouldn't even come close to being sensible.

The bottoms that were about to fall off their meager hips? Almost snapping from their butts exploding outward in the same vein as their tits, with another firework going off inside their minds to herald the change. And the parts that didn't end up tearing? They got wedged into their brand new bubbly bimbo butts, ensuring that those asses would always be nice and bouncy...

But that was just their asses and their tits, their most alluring areas. It wasn't just those parts that ended up getting changed. No, there was still way more to go. And it started with the subtle tan that was covering their bodies.

Not too deep to the point where they looked like they might be just as degenerate as Ero. Yet at the same time deep enough that it was clear that they loved to be out and about in the sun.

And to match the theming of their bikinis, their hair started to turn a much more natural shade of blonde. Fitting their brand new American Bimbo aesthetic, which only grew stronger and stronger the more they heard those fireworks going off inside their minds.

One by one they went off. And the more they went off, the more they could feel their nethers slickening up. They were getting so wet and needy. Ready for a big ol' cock that could just drive them wild with pleasure. All thanks to the Bangs going off inside their heads..!

Bang...

Bang..!

BANG!

"CUMMINGGGG!"

Momiji and Yuuka both cried out in overwhelming delight as their nethers gushed, lots of fresh feminine cum squirting its way out of their respective holes. All while they were left with a brand new pair of fat red cocksuckers that had popped out in response to all the fireworks in their heads...

They looked like a pair of bimbo sisters that were ready to stalk the beaches. And honestly, if not for the fact that there weren't really any beaches in Mimoto, they might actually have gone there to do just that.

But since there were no beaches, the two Americanized Bimbos decided to stalk the next best thing...

---

"S-Stooop... C-Can't... C-Can't think straight..."

What better thing for the two to bond over, as their minds had been blown to complete bimbo bits, than their dear Senpai? Sure, he was a lot smaller than he was before. Maybe because they had grown on top of getting sexier. Maybe because of their platform heels. Maybe because he was simply cute.

Whichever the reason was, Tsubasa was struggling between them as they held him in between their breasts. Trapping him in between those mighty American melons. All while peltering his face in more and more kisses...

"Big man..." "Lover boy..."

To make matters worse for Tsubasa, who was already having a tough time given how they were restraining him and holding him, they were whispering real enticing stuff into his ears. The kind that he had so much trouble resisting. The kind he had dreamed of hearing, and here they were, giving him exactly what he wanted.

He had just left the library! And then these two American Amazonians were right there waiting for him! Picking him up and kissing him and squeezing him and making it hard for him to do anything except moan as his crotch throbbed more and more...

It wasn't just that it was too much for him. It was also that he could tell exactly who they were. There were only two people that would go this far for him. And the kisses clued him in.

"M-Momiji... Y-YuuuukaaaaahhhHHHHH!"

He wanted to try and make them stop. Oh believe him, he wanted to do that. But he couldn't. Not while they kissed him like this. Not while they overwhelmed him more and more. To the point where his eyes were rolling into the back of his head...

To the point where he ended up letting out a scream that encapsulated just how good it felt for them to spoil him like this. He couldn't hold back at all. All he could do was cry out in complete and utter pleasure. Enamored by it all...

And as a result of how badly they had loved him, the power that had changed them into these forms changed him as well. His body expanding outward just as violently as theirs had, with his clothes ripping and tearing apart to reveal the same sort of huge tits as theirs...

Even a flag bikini of his own, which was struggling to contain both his tits and his cock... Both of which he couldn't help but want to use, as each of his most intimate parts twitched...

Even his hair and his skin changed to match the two American Amazons, whose bimbofied looks matched his perfectly now. The only difference between the three of them was the cock resting between his thighs. A cock that was threatening to snap his bikini bottom right off...

A cock that trembled further, as the two bimbos finally let go of him. Not that they could hold him after he grew like this. And now that he had something for them to worship... More so than before at any rate...

The kisses began anew. And his cries only continued to grow louder and louder as they showered him in their smooching love. Their plan had succeeded. And yet, it almost felt as if the two of them were forgetting something in their horny haze. Something about a competition between the two..?

No. That didn't matter. As long as he was happy, then they were happy. Even if he was an Americanized Amazon like them...

Even if he kept on cumming every time they kissed him...

As long as he was happy... Ehe...
