[Muscle Growth, Weight Gain, Slob]

"Aaaaadmiral! Aaaaaaaaadmiral! Are you here?"

A loud and proudly American voice echoed out through the office belonging to the naval base's Admiral, as that very same proud American popped her head into the office to make sure that the Admiral in question wasn't hiding away inside it. She had been looking for her for so long, and yet it seemed like she wouldn't be able to find her. Which wasn't great, she had so much she wanted to talk with her about since it had only been so long since she first arrived at the base.

The American in question was the Shipgirl, Iowa. This base was nowhere near the kind of home that she was used to, as it belonged to the Japanese and by all accounts they were supposed to still be hostile towards one another. But her Admiral had been the first to accept her presence, and the rest of the Shipgirls at the base were friendly enough to the point where there might actually be some sort of progress for the two nations in the future.

Not that she was really a part of the intricate details of national diplomacy like that. No, Iowa had gone to her Admiral's office to try and see if she couldn't tell her a couple of things. Like how much she adored her, and if there was anything she could do for her. Stuff like that. But it seemed as if her Admiral wasn't currently in.

"Weird, I didn't hear Admiral say that she was heading out for the day." Iowa scratched the back of her head. Was this just something the Japanese did? Not report to their officers to keep them in the know? Oh well, if that was the case, then she'd just have to wait in the office.

At least, that's what she was originally planning. Right until she actually took a few steps into the office. As an American, it was her natural instinct to go snooping whenever she wasn't doing anything. Why? Well, she didn't really know why. She just knew that she liked to know things about the people she worked with. Could always come in handy, especially if she needed to get a gift.

"Hope you don't mind, Admiral! I'll just take a few peeks. Nothing big, just a teeny tiny peek. I promise I won't mess up anything!" Iowa said out loud as she started digging through every single piece of furniture in the office. It didn't matter if it was big or if it was small. As long as she could find something that seemed juicy enough.

Unfortunately, it seemed like the cupboards were just full of papers and the drawers were just full of even more papers. It was like she had been hiding away all her paperwork. Wait, was her Admiral a slacker? "Admiral, I'll make sure you know to do your duties on time! That way you can have more fun and enjoy the liberty of no responsibility!" Iowa cried out as she vigorously pumped her fist into the air...

And in the process, bumped her flat belly straight into the table, causing her to let out a very brief groan as she rubbed the spot that she had bumped. She shouldn't get too excited, she had a habit of moving too much when she got that upbeat. But as she rubbed that spot, she noticed something.

"...Admiral, remember your phone." Iowa laughed a bit as she felt indirect pain at what she saw laying on the table. Her Admiral had left her very expensive looking phone on the table. Not only that, but it was unlocked. Which meant that she could easily just grab it and start scrolling through the various items that she had saved. Items, pictures, videos, anything-

Iowa very nearly dropped the phone as she opened the very first video she found, but thankfully she managed to catch it before she broke it. And then she placed it down carefully, letting it rest up against one of the books that were still on the desk. All so she could make sure she was absorbing every little bit of what was happening on screen.

It was an animated video displaying a very strong looking woman pumping iron. Not only strong, but thick. She had wide hips, strong thighs, strong arms, everything. She wasn't just strong, she was beautiful too. And it wasn't the only video that her Admiral had saved. There were plenty more where it came from, even a couple where the strong women were pinning much smaller women, not unlike the Admiral herself, between their thighs and forcing them to submit everything to them.

She kept scrolling through the images saved on her Admiral's phone, and they reflected the same tastes. Strong women. Beautiful women. All of them carry a level of dominance that would be almost impossible to find in somebody like her. Even the delicate Shipgirls native to this region weren't able to be this strong. So this was the kind of woman she was into..?

Iowa took a deep breath as she carefully pocketed that phone. If her Admiral had forgotten it once, it would be totally okay for her to take it. Because she'd probably forget she forgot it in the first place. And with this in her hands, she now had a piece of information she could act on.

...She knew that her Admiral liked strong women. She wanted to thank her Admiral for what she had done to make sure she got along with everyone and made her have such a wonderful time at this base. That meant that if she truly wanted to thank her, she should act on this information. And if that was the case... Then she needed to make sure that Akashi had exactly what she needed. So she could get started as soon as possible. She needed to get strong. Strong enough to look just like those strong women saved on this phone. And with her head held high, she let out a declaration...

"Don't worry, Admiral! When we meet again, I'll be ready for you. And you'll kiss these thighs too!"

Before hurrying out of the office and quickly speeding away so she could get started.

---

To say that Iowa dove headfirst into training would be an understatement. And to say that she tried to hide it would be an exaggeration. Because somebody like her, a girl with more breasts than brains, couldn't really hide anything.

It was why she was wearing a sports bra with the American flag plastered across it. It was why she was wearing a set of incredibly short shorts that exposed as much of her naked thigh as possible while also being decorated with that patriotic flag. And it was why she refused to eat more carbs than necessary, something that she had to ask Akashi to help her with, all for the sake of making the path toward strength easier.

She didn't even really hide her training room. She had just set up a little space at the dock with a couple of weights and other types of training machines. All so she could go straight from missions to pumping iron. It wasn't like anybody really noticed her either, by being in plain sight people just looked the other way because it didn't concern them. Letting her work out to her heart's content as her body slowly but surely grew stronger and stronger.

And the results really started pouring in. Her arms were getting bigger. Her thighs were getting larger. Her stomach was getting stronger. She could feel that power coming through, all thanks to the dedication to the routine. And it made her happy. Because little by little, she was getting closer to the kind of figure that her Admiral loved. The kind of figure that she wanted to be dominated by.

Sure, she was getting incredibly sweaty too, and this routine meant that she wasn't really focusing on her hygiene or anything, but it was worth it for the results. Besides, it meant that people weren't bothering her. And if people weren't bothering her, then her Admiral wouldn't take notice either. Which meant that she could keep pumpin-

"What exactly do you think you are doing, Iowa?"

Iowa blinked and very nearly dropped the bar she was holding over her head, only to quickly correct her grip and let it fall back down onto its rest, prompting her to sit up and take a deep breath as she looked at the girl that had bothered to stop her. "What? Can't you see what I'm doing? I'm working out, getting real nice and strong and buff!" The American grinned, flexing her muscles a little as a couple of them popped in response. Not a lot, because she wasn't disgustingly muscular, but you could definitely see her body growing tense.

The girl that had come to stop her was the flagship of this entire fleet she was assigned to, Yamato. A dignified Japanese Shipgirl who saw something like strength to be more abstract. Strength was what your character exhibited. It was not something physical like muscles. It was dignity. It was grace. It was following orders and making sure that the job was done correctly. Which was why she currently completely contrasted the American in front of her in many different ways.

"I see." Yamato said, smiling softly. "Do you know what that entails, Iowa? Do you know what happens when you spend time exercising, when you could be dealing with the Abyssal tide? You know as well as I what might happen if they break our front lines." Her voice was stern, yet soft. She maintained that character of hers, even when she disagreed with somebody.

Iowa nodded and stretched a bit as she climbed off the bench and went over to one of the other machines, grabbing a hold of the handle that controlled the machine as she started tugging it back and then letting it retract. Replicating the motion you'd do when you were trying to row a canoe. "I mean, you're doing a great job with all that Abyssal repressiing, Yamato. And it's not like I'm doing this all day, you know? I do my part during missions, then I relax by doing this!" She explained, all while not breaking a sweat while training. It was like second nature to her. She could breathe easy as she kept on repeating the same almost repetitive motions. Breathe and relax and just let it all keep repeating...

Yamato's eyebrow twitched as she slowly watched this inane action. This American had been grinding against her nerves ever since the two met. While yes, she would not actively show her hostility, and definitely not imply that she was useless, she could just barely restrain her overall contempt for her. Why did somebody like her have to fight alongside them? As much as the higher ups had told her that this kind of mindset wouldn't fly in this current age. But she didn't like her. She thought of her as uncouth and disrespectful.

Something that only got worse as she became more and more aware of how the blonde had started to neglect herself. Whether it was subtle traces of unkempt armpit hair, her body having sweat pour down and soak into her seat or gather on the ground below, or the very subtle hint of pubic hair stretching under the waistband of her shorts. Iowa was slacking. And it was becoming more apparent that if she kept going down this path, then she would not only get on her nerves, but she would project a different kind of image for the fleet. An image that was highly displeasing.

"What does the Admiral think of your current behavior, Iowa? Do you have her approval? Do you have her attention? Have you even bothered to try and check with her to make sure that any of this is permitted? I highly doubt that she would want something like thi-"

Before Yamato finished talking, she found herself nearly assaulted by a phone hitting her face. It was only thanks to her highly trained reflexes that she was able to catch that phone out of the air, her heart smashing against her chest as she looked at it and glared past it to make sure that she wasn't missing anything on Iowa's face.

"Take a look, Yamato. I might not have permission, but it's definitely something that the Admiral likes. I wouldn't be doing this if it was just to get strong, I know muscles don't work against Abyssals. But I wanted to tell her something important, and I thought this would be the best way!" Iowa cried out as she continued exercising, not at all bothered by the many words that Yamato had tried to pile onto her. All that she wanted was to make her Admiral happy. Anything besides that was either not important or a cherry on top.

Yamato was at first furious, because she recognized the phone. In fact, her Admiral had been asking everyone if they had seen it. Nobody had, not until now. But that furious mood gave way to shock as she very nearly dropped it, her rather generous bosom doing her a favor as it caught the phone right in between those incredibly soft pillows.

She had seen the muscle videos. She had seen the muscle pictures. All within seconds of one another. And steam seemed to pour out of her ears as she had trouble processing what she just saw. Her Admiral liked something so... So... R-Rough? She seemed like a kind and gentle individual, just like the natural wives of Japanese culture. To think that she craved something so vulgar!

No, she mustn't get upset. It was what her Admiral loved. But if that was the case, then she would love Iowa even more because of the way she had been training herself. Which was something that she just couldn't permit. No, she needed to make sure that this training would fall apart. Otherwise, her Admiral would keep falling further and further. And she couldn't allow that to happen.

Yamato cleared her throat as she carefully pulled out the phone, putting it on one of the other machines just to make sure it was safe for the next little while, before turning her eyes on Iowa as she smiled without a lick of sincerity. "Well then. If you want to make the Admiral happy, then I suppose I have no choice in the matter. However, I do believe you're neglecting a couple of important factors in pursuing muscle mass, Iowa."

"Eh? You know how to make my muscles bigger?" Iowa asked, and Yamato nodded. "Well, spit it out! You can't just keep that hidden, I wanna know!" To say that she was excited at the prospect of getting even bigger for her Admiral was an understatement. Even though this was very clearly a trick that she just couldn't see through because she hadn't yet gotten a taste of the deception that Yamato could put up.

Yamato smiled. Oh yes. She would help her alright. Help her become undesirable in the eyes of the Admiral...

---

Training from that day onward became much more intense. And it was all because of the method that Yamato started to tell her about. A method that she should've thought about from the very beginning. Something so simple that she honestly just wanted to bash her head against a wall to make sure that she remembered it this time.

Eating smaller meals wasn't a good thing. She needed the energy to keep working out. Which was why Yamato started to bring her fast food. The heaviest kind of food that money could buy. Not only that, but it was authentically American too. How she had managed to get ahold of that on such short notice was a mystery to the American, but she wasn't about to look a gift horse in the mouth or worry about something so trivial. She needed to focus on getting stronger, and that meant keeping up her routine while eating more at the same time.

Now, she had been skeptical. As far as she knew, especially from all those infomercials that she had binged while she was on the way from America to Japan, she wanted to keep low on fats and carbs and sugars. Yamato's idea sounded more than a little wrong, but she went along with it. And she was blown away by how wrong she had been, because her muscle gain almost doubled. She was definitely getting stronger, and it was in such a short timespan too!

So naturally she went along with every other plan that she had. Stop worrying about her hygiene because it was taking more time away from her workouts? Done! Eat even more so she could work out until midnight struck and then a few hours past that? Done! Soda-filled energy drinks so she could pull all-nighters? Done!

Sure, putting that much effort into pumping iron was actually a bit much come to think of it. She could feel her muscles aching. And as a result, she'd eat more. Which meant that it grew bigger. Which meant that she'd ache more, and so on and so forth. To the point where she slowly started not really working out. And it almost felt like something was wrong. Almost.

But Yamato assured her that she was strong. And she proved it by having her lift an iron bar with every single weight attached. She could lift it without a problem. Sure, she had grown a lot bigger, but she was just as strong as the girls that were in that phone. Which meant that she would be able to handle her Admiral with ease. It was her chance to go and tell her everything she wanted, straight to her face.

Iowa thanked her at that point, and let her body lumber towards the Admiral's office. All while neglecting to notice the malicious smile on her trainer's face...

"I'm never gonna get my favorite phone back..."

The Admiral sighed as she slowly rubbed her hands through her hair. It was frustrating that her private phone, where she kept all her porn, had managed to disappear. She was sure that she had left it on her desk the day she had to hurry out and conduct an emergency meeting with the Fleet Admiral about some of her choices, but who would have taken it?

Aaaahhh... She just wanted to lean back in her chair and watch some hot muscle chicks pump some iron or make the world quake through their sheer strength. It was her favorite thing. Well, it was one of her favorite things, but it was definitely the thing that made her heart bounce the hardest. She just wanted a big muscle gf that could pinch her between her thighs and then destroy her completely. That was what she craved.

But she wasn't going to get one. There was no way that she would have that desire fulfilled. All of the Shipgirls in the Japanese navy were designed after specific specs. Even Musashi, who served as one of the Fleet Admiral's personal attendants, wasn't even close to being as buff as she wanted. She needed somebody that oozed strength. Somebody that towered over her. Somebody that could crush her like a watermelon and still expect her to say thanks for the experience. That's what she needed.

*KNOCK KNOCK*

"Aaaaadmiral! Iowa here, mind if I come in?"

The Admiral blinked a couple of times as she heard that sound. What was that? What exactly was that? That couldn't be Iowa. Iowa wasn't nearly that strong. The Iowa that she was familiar with was a fat-tittied American that was friendlier than anybody she had ever met. But she wasn't strong. This had to be some sort of joke that she hadn't picked up on. That was the only rational explanation, her heart smashing against her chest as she tried to rationalize what she was hearing.

"Uh. Y-yeah. You can come in, Iowa. I'm not busy." She said, carefully breathing to try and calm her heart down. She had to make her heart calm. Otherwise she'd think that she was actually about to see somebody properly muscular. Somebody that shouldn't exist in this navy. There was no way-

*STOMP*

The room itself shook underneath the weight of the foot that just made its way into the office. And it wasn't the only stomp that echoed out, nor was it the only shock rushing through the room. It kept on happening, all while the owner let out a soft yet deep giggle...

"Look, Admiral. See anything you like?"

The Admiral felt so much sweat pouring down her head as she looked towards the blonde Shipgirl with her heart smashing against her chest even harder than before. She didn't believe it. She couldn't believe it. But there it was. Proof of what she had wished for. Proof that wishes could come true. Proof that there was a Shipgirl that could fulfill her needs.

It was Iowa. And she was massive. In very different ways too. Because not only had she grown at least a couple feet which caused the Admiral to just barely reach up to her chest if they were to stand right across from one another, but that wasn't the only thing that had grown. It was just the first thing she noticed.

Her body itself had experienced quite the growth spurt too. Mostly in terms of muscle, as there was a subtle layer of tone from head to toe. She looked like she had been training so hard that her muscles would start popping if she started to flex. Which instantly made the Admiral's chair grow nice and soaked as the juices poured out between her thighs. She had never seen somebody this strong before. Even in the videos that she had been able to download from various sources and olympic competitions when she had tried to train to get that strong herself, there was not a single woman that looked as strong as Iowa..!

And there were no strong women that looked that fat either. To say that Iowa was fit would be... Not incorrect, but also missing the point. While her body was certainly covered in a certain layer of muscle, that didn't stop the rest of her body from being too thick. Whether it was a subtle layer of flab running along the side of her arms, or the way her thighs were unable to truly be pulled apart. And that wasn't even mentioning that utterly enormous belly that was stretching out from her midsection to the point where it was threatening to break something the moment it made contact. It wasn't really sagging either, it was completely and utterly firm. If you were to touch it, you'd probably start sinking in, but otherwise it looked like it would maintain its shape completely.

There was another thing that stood out about this massive woman made out of muscle and fat. And that was the sheer lack of hygiene. The moment she had stepped into the office, her natural musk started to fill it. Permeating through every little corner that it could manage to slink into. Filling it all and making it impossible to escape. And that was just the smell, the bushes that had started growing near her crotch and inside her pits had grown so thick that it was impossible for sweat or musk to pour out, turning them into proverbial death traps with how concentrated it all was. She was hairy from a lack of personal grooming, she was sweaty thanks to her lack of properly maintaining her hygiene, and her workout uniform had been soaked so badly that it almost looked like she had been cumming in it... Then again, it wasn't out of the ordinary for the strongest women in the world to cum from working out...

"I-Iowa..?" The Admiral let it all sink in, and that was the only thing she managed to say after it all hit her like a train. Yes, Iowa had become the kind of woman that she wanted. But that was only in terms of strength. The rest was something she would've never expected to see paired with strength. It was a kind of aesthetic that seemed so wild. So unrestrained that she thought she was dreaming. And honestly, thanks to the thickness of the musk pouring around her, thanks to the sheer intensity of it all... She very well felt like she was actually in one of those deeply intimate and extremely horny dreams...

It didn't take long for her to get knocked out of that line of thought however, once Iowa took a few more powerful steps towards her desk. She could feel the weight of that powerful Shipgirl weighing down on her just with her sheer presence. Her musk, her size, her everything. It was making the Admiral's eyes slowly grow hazy. Was she cumming, or was this sensation inside her something else..?

"Here, Admiral." Iowa said, with such a deep yet sensual voice. Even her voice had grown stronger. Even though she was so much bigger, even though she was so strong and so fat that she was practically unrecognizable compared to her original self, she was still focused on giving her Admiral exactly what she had planned on. And that meant that she had to get a little rough.

Her Admiral didn't even try to move as that massive girl took a seat on her desk, making that wood creak in despair due to the weight of who was sitting on it. Even more so as the Shipgirl reached down and grabbed her Admiral, yanking her onto her rather massive lap. Even though her stomach was sticking out a lot, there was still plenty of real estate left to occupy thanks to her equally enormous thighs.

"I-Iowa... Iowa..!" Her Admiral cried out as her cheeks were flushing brighter and brighter red. She didn't know how to properly tell her what she felt. She didn't know how to make her stop. She didn't know if she wanted her to stop. Why should she tell her to stop, if it felt so good to be in her presence. She was trembling with every breath she drew. It didn't matter that she had never considered fat and a lack of hygiene to go well with complete and utter strength. All that mattered was that Iowa was turning her on so badly that she never wanted to come down from this high..!

Her Shipgirl smiled as she saw all of that pleasure pouring off her Admiral's face. And the way she would reward her was by stuffing her face straight into her bushy armpit. "You'll love this, Admiral. If you love the rest of me, then get a whiff from here..." She said, shivering a bit herself as she felt that head trembling inside her proverbial jungle. God, it already felt so good and she had only just gotten started? She definitely had to thank Yamato for helping her, because her Admiral loved it!

It wasn't quite right to say that her Admiral loved it. She still wasn't sure what she thought of all of this. She knew she was turned on by it. She knew she didn't want it to go away. But was that love? She didn't quite know. The only way that she'd know was if she took a deep whiff of this smell from the depths of this armpit.

*SNIIIIIFFFF*

Her audible sniffing grew so powerful that she was on the verge of passing out right then and there as the concentrated smell went straight for her brain. It felt so unfathomably good that she wanted more. Even though it was breaking her, even though it was something that she never should've indulged in, she wanted more. Which caused her to try and stuff herself as deep into that pit as possible...

Before Iowa pulled her out, letting her head rest on her breasts and her strong stomach. Letting her feel the sheer thickness of that mound and nearly sink into it, with only the subtlest muscle keeping her from sliding fully in. All while she had a perfect view of her strong, hairy, smelly, fat Shipgirl.

"Well, Admiral? What'd you think? You like what you see? You like what you smell? You like what you feel?" Iowa asked a couple of questions, all with that new and powerful voice of hers. It was so amazonian, so dominating that it was impossible to go against her words. Not that you would want to go against her after you really let her appearance sink in.

Her Admiral trembled... And let out an incredibly immodest scream as she had the most obvious orgasm that Iowa had ever seen. In fact, you could see her pants sliding off from the sheer intensity of the cum pouring out of her pants, her body trembling with every breath she drew as more and more of that slick yet sticky stuff poured out. "I...Iowa..."

One look at her, and it was clear that she had been charmed. Her eyes had turned into muscled hearts, and she was actively nuzzling into the wonderful belly and enormous tits. She loved the sensation. She loved the smell. She loved the flab. She loved the sag. She loved the power. She loved the firmness. She loved every little part of Iowa, to the point where she audibly huffed her scent once more, before collapsing as she very nearly passed out, only able to let out a very weak "L-Love you, Iowa..."

Iowa giggled. She had managed to make her Admiral appreciate her love. And since she liked it so much...

Maybe she should get even bigger, to see how addicted her Admiral could end up…
