[Breeding, Size Difference, Age Progression, Shortstack TF]

"How did we get lost!? How?! We beat the Princess, how come we can't get home!?"

"Ehehehehe, guess I led us down the wrong path. I must've been too used to American waters. Sorry, Ryuujou!"

"Don't give that sorry, you American cow! And especially not while your tits are barely covered up thanks to your injuries!"

"Ahn! Not so hard, Ryuujou, they're very sensitive!"

"Please, both of you, we don't have to fight. We just have to try and figure out a way back, or at least try to signal to the base. Worst case scenario, we'll sleep in shifts to make sure Seaport Princess doesn't end up running away."

"Easy enough for you to say, Mutsu! You're just as much a cow as she is! Can't you share some of those tits so I can have big ones too!? Come on, I just want a little bit, not a lot!"

A frantic scene was happening out at sea. Three allied shipgirls, Ryuujou, Iowa and Mutsu, were practically stranded after they had been unfortunate enough to run into one of the stronger types of Abyssals, the Seaport Princess. Sure, they shouldn't have engaged her in the first place, but getting rid of her now meant that they didn't have to worry later.

Which was why the Seaport Princess, barely tied up since she surrendered to their continued barrages after having taken too much fire, was watching the youngest of the three boats blame the others for their current situation. If anything, it had been the large white-haired Abyssals' fault, since she had been the one that struck their communications equipment the moment they engaged in combat. And she couldn't use her own, as part of the agreement that kept them from finishing her off. She just had to sit there and watch them.

Were they always like this? Were humans like this as well? She didn't know the truth, all that she knew was... It was actually kind of fun seeing them interact, even if one of them was clearly more aggressive and apprehensive towards the others than her friends, which only served to highlight how different they were from the hivemind-like Abyssals...

Ryuujou huffed as she backed away from her two large-tittied compatriots, a bit of steam pouring out of her head. The longer she spent alone with them, the more she was being driven crazy by just how large they were. She wanted to get away from their oppressive sizes, but how? How was she going to be able to do that?

"Oh, Ryuujou. It's okay, you'll end up as big as us one day. Just remember to drink your milk, you're a growing girl!" Iowa, ever the cheery American blonde, totally believed in something as simple as that. In fact, she thought it was how she had gotten so big in the first place. And the sheer size of her breasts was a testament to that, considering she had the biggest even when proportionally compared to the pale-skinned Abyssal that was about thrice their size.

Mutsu just shook her head a bit. Those two were destined to never get along. Because no matter what, something would set Ryuujou off. She was an envious little girl who could never truly get over the fact that she was still so miniscule compared to her friends. Whether that was height or breastwise.

As the four continued to just idly sail around in what were essentially circles, since none of them had a way to navigate the seas as previously mentioned, hope slowly started to dwindle inside their hearts. Were they going to be lost to sea and captured by the other Abyssals that no doubt wanted to reclaim Seaport Princess? No, there had to be a way...

Iowa clasped her hands together. And she prayed. Because if there was anybody that was going to get them out of this mess, it was God! And like a pure-blooded American, her belief in God was comparable to her belief in her friends. God was going to make sure that they could return safely. As long as she prayed for him...

All four were given a sudden shake thanks to the sound of a fog horn blasting past them, and the sight of a one-manned vessel approaching their position. A simple speedboat, flanked by another shipgirl from what they could make out from this distance. Somebody had found them, it just wasn't their Admiral...

That fact was only reinforced once the speedboat managed to reach them properly, and they got a look at the one driving it. It was a young man, around the same size as Ryuujou, wearing gear that denoted his role as an Admiral. At least they had been found by a Naval Officer, instead of some crook.

What more concerned them, especially Ryuujou who started to bite her lip in frustration, was the shipgirl that had been strafing the boat. It was Kaga, one of Ryuujou and Mutsu's fellow Japanese boats. Only, she was grossly gravid. Her stomach was sagging ever so slightly as a few bumps of activity made their presence on the surface of her belly, while her breasts were heavy enough to carefully rest atop of her enormous mound. Shipgirls weren't supposed to get pregnant, so how..?

"Mutsu, Iowa, Ryuujou." The boy said with a smile as he stood up, adjusting his cap and revealing a special emblem planted in the middle of it. It depicted a hand grasping the earth, quite a different emblem than anything they had seen before. "As of today, you are all relieved of your prior duties. All the paperwork has already been processed, so don't worry about it. All you need to do is follow behind this boat, and Kaga will help you all get nice and comfy at your new base. All under me, Admiral Atlas Grimwald. Any questions?"

They had a lot of questions. But they could wait, they much preferred to just get out of their current sticky situation and back to dry land, alongside their captive so they wouldn't be in danger of retaliation out at sea.

Atlas smiled as he watched them all follow in one neat line. All while eyeing the ring on his Kaga's ringfinger. He had already claimed one, and after all these arrangements he had made to isolate these three and the bonus Abyssal..?

It was time to stake his claim on them as well.

---

Iowa was happy to get back to someplace that was actually warm. And a place where she didn't have to endure constant yelling from Ryuujou. Sure, the girl was still nice and cute and young, but she only had so much patience. If she could just get some time alone like this, then everything would be just fine...

Still, as she looked at herself in the mirror, she couldn't help but wonder something. Simply put, instead of bothering to give any of the boats a replacement uniform, their new Admiral had given them something he deemed more appropriate. In Iowa's case, that happened to be a star-spangled sling bikini that was doing its best not to tear as it stretched across her tits.

Iowa couldn't help but giggle a little as she observed her figure in the mirror. It was as bountiful as ever, and the brand new bikini was actually really nostalgic. She had been one of the first boat girls to be transferred from her home country to Japanese jurisdiction during the early days of the war against the Abyssals, so to get a taste of home...

"That cute little boy has really good taste!" She giggled, stretching and watching her whole body bounce. Simultaneously blushing ever so slightly. Geez, had she been putting on weight without realizing it? Maybe, just maybe, she should keep Ryuujou from learning about this... Because there was no way she wouldn't be influenced by knowing that one of her greatest rivals in the chest department had them because she was getting nice and fat.

Still, she had to wonder. Was there an ulterior motive to all of this? ...Nah, there couldn't be. He was too nice to be planning something. She just had to accept that he wanted to give them all something nice, something they could appreciate, and then repay that generosity with her loyalty and hard working attitude.

"Iowa? I'd like to talk to you for a moment. Just a little, so I can get to know you better. Your transferral to my care was rather abrupt, after all."

The voice of her brand new Admiral echoed from behind the door, prompting her to run over with a big smile on her face as she very nearly threw it open. "Of course, Admiral!" She cried out in glee, more than happy to get nice and cozy and intimate with somebody else. Especially one that seemed so nice.

Not to mention cute! Just looking down at him, Atlas was adorable dressed in that Admiral's garb. He wasn't even half as tall as her, owing to her amazing American construction, but that didn't matter because it just meant that he was extra adorable. So much so that she could very nearly pick him up and snuggle him around.

Atlas smiled in turn. "You're a positive one, aren't you, Iowa?" He said with a gentle tone, making sure to close the door behind him as he walked inside. "Then again, you put that bikini on the moment you got it, even though Ryuujou was hurling abuse at you for trying to compete against her. What's the deal with that, anyhow?"

Iowa giggled. Something about how he was calling her positive was making her all fuzzy inside. "Oh, Admiral, you charmer. Try harder and I might just fall for you." She chimed, not entirely sincere. She wasn't sure if she was going to get that intimate with a boy his size, but it was nice to tease him. Just so she could see how he'd react. "And Ryuujou's been doing that since we met. Sometimes I think she might actually hate me, but after a few minutes between these Grade A American tits, she's usually calmed down and stopped complaining." The blonde American said as she pushed her palms up against her breasts, squeezing them nice and tightly...

"If you insist." Atlas said as he reached up and put his hands on hers, helping her squeeze those breasts together. "I'd love to have one as beautiful as you by my side, Iowa. Your smile brings light wherever you go, and your body screams with loyalty. If there's anything I'd want, it's you." His soft voice turned real smooth as he started making moves right then and there. She did insist that if he tried harder...

Iowa's heart started to smash against her chest as she looked down at the boy. What was this feeling inside her? How had he managed to make her feel this way with just a few words? She didn't understand, but at this point she was blushing real badly. All while her nethers were growing nice and tight as the sling started digging into her crotch. "M-Mmph, that's a bit too hard, isn't it?"

"Not when you're blushing that hard, Iowa." Atlas said as he got all the way up on his tippy toes, grabbing ahold of her cheeks and helping her bend over ever slightly so their lips could lock together. "Besides. I don't exaggerate. You really are beautiful, and I really do want you, Iowa."

He shouldn't be saying this. They had been together for at most an hour. And here he was, trying to make her his. The worst part? It was working, her eyes were rapidly swapping between the usual stars that symbolized her patriotism and hearts that showed her developing and overwhelming love. "A-Admiral..." She muttered, trying to back away ever slightly from him. Even though she was falling in love with him, she wasn't sure if she wanted to get down to dirty business right here and now. It would be...

Of course she couldn't get away once they had locked lips. By trying to get away, she was only making her Admiral desire her more. So much so that he swept her off her feet with a momentary shove, only to catch her before she hit the ground. All while his bulge now rested up against her pussy. "Iowa. I want you. And you will be mine. Isn't that what Americans do, take what they want?"

She didn't really have anything she could say to refute him. Especially since she had practically sprung a leak down below with the proverbial waterfall of pussy juice rushing out of her hole. All she could do was look at him with her eyes having completely turned into hearts, hoping that he would do what he said he would do. If he wanted to stake a claim on her, then he really had to make her his...

Atlas smiled. She had become quite docile once confronted by a proper husband. So he did exactly what he said he did. By grabbing her thighs and forcing her legs to bend closer to her chest, she would have a very difficult time trying to resist what he did next. Not that she would resist, but this dominant position would only add to the sheer delight.

Once he had shifted her position enough to the point where she was firmly in the Mating Press position, he grabbed ahold of his pants and yanked open the buttoned-up pocket leading to his crotch, revealing a cock that was even larger than some of the cannons that the shipgirls used during combat...

Iowa let out a powerful moan as that rod docked with her pussy, her body trembling. She was used to sex, since it was something that commonly happened back in America. What she wasn't used to was such a virile young man using all of the power in his hips to slam into her with as much force as he could muster. Slamming and ramming again and again, until her moans started to meld together with one another, the pleasure from every thrust leaking over into the next...

Atlas knew how to fuck. He knew what to do to completely and utterly stimulate somebody like her. He had learned it thanks to Kaga, his existing Secretary. She had been the one to coax him down this path, after showing that there was a horny woman hidden behind the stoic veil. Which was why he was doing his best to reveal the horny woman within Iowa as well.

In and out. In and out. As he kept thrusting into his brand new ship girl's hole, he was getting exhausted. She was thick, and that meant that it was a bit difficult to properly pleasure her. But there was something he could do to alleviate that, and it happened to hang off her chest while being nicely cupped by the gift that he had previously given her.

Iowa let out an even stronger moan as she felt the young Admiral's teeth sinking into her areola, causing her to very nearly clench down on his cock like she would when she climaxed. But once he started sucking, her arousal lowered ever so slightly. He was trying to nurse from her breast. Even though she hadn't been pregnant, even though shipgirls shouldn't be able to lactate, he was still... He was...

She didn't get to think about the absurdity of it all for long before she felt something rush out of her chest. And instinctively, she started to gently rub the young boy's back. Even though he was thrusting so hard into her, even though it felt like she was about to be overcome by a wave of pleasure that could sink anybody and make it hard for their true selves to resurface after tasting this pleasure just once... She just wanted to keep treating him like he was an innocent babe.

Atlas kept suckling as he felt the way she warmly rubbed away at his back and his head. It was comforting. Almost as comforting as Kaga was after a long and heated bout of breeding. Which meant that they were both getting way too close. But as long as he could suckle out a few droplets of milk past the sling bikini, he'd have everything he needed to finish and stake his claim...

Iowa let out a moan that almost sounded like a cow mooing with how intense it was and how dragged out it was, before the tiniest bit of milk started to shoot out of her nipple. It had only just been drooling before, but now it was a proper and steady stream that was pouring right down her Admiral's throat.

Powered by that stream of nutritious goodness, Atlas withdrew his hips for a moment before he slammed his cock as deep as it could go, opening his American lover's womb in the process. And with nothing getting in his way, the boy let out a powerful scream of his own as he inseminated one of his brand new boat girls.

Iowa joined in on screaming in pure delight as she was being filled with cum. Not just a little cum either. The boy was unloading as much ammo as he possibly could into her womb, resulting in her stomach quickly being bloated and stretching out the lower part of her sling bikini as her womb struggled to keep it all inside. And it was a dutiful womb too, because not a single droplet was spilling as her stomach started looking like she had been pregnant for months even though this was the first time she was being properly impregnated.

As Atlas pried his lips off Iowa's nipple, he smiled and did his best to lean up and kiss her right on the cheek. "I ask again, Iowa. Be mine." He didn't want to make it too complicated. Not while she was still recovering from the afterglow.

The American lover's response was to kiss him back on the lips, stars appearing in those heart-filled eyes of hers. "I'll be yours, Hubby..." She giggled, accepting this as if it came naturally to her.

One down... Three to go.

"How come I don't get clothes like theirs!?"

Next on Atlas' list to claim was the young Ryuujou, and he was not at all surprised once he stepped into her private quarters and was quickly blasted with the usual kind of abuse from the short-statured girl. At least he had built up tolerance prior, because otherwise he might've done something real awful to her for what she had just done.

"Well, I don't own a pair that fits you, Ryuujou." The Admiral had to be blunt as he looked at her, even though it resulted in a pillow barely grazing his face as it flew past him. "But that doesn't mean you're going to go giftless. I had to pull a few strings, which is why it took so long."

Ryuujou raised an eyebrow, another pillow ready to be tossed after being primed in her hand. "You better not be trying to trick me. I know better than to trust a guy I've never met. Unlike that blonde American Cow!" She hadn't taken kindly to the fact that Iowa was now getting all nice and handsy with the Admiral Because that meant that he had done something to her. And he had even gotten milky too, which just made things worse. She didn't need that constant reminder that she was much less fertile than somebody from another country!

Atlas just smiled at the sight of the youngest ship girl's aggression dying down, before pulling out a single Magatama from his pocket. "I had this blessed by countless priests from the mainland. Making sure that it had as many blessings from different deities that could help you grow to the form that you've always wanted. Now, I don't know if it's actually going to work, considering the kind of reputation that magic of that caliber has... But you're standing right in front of me, Ryuujou, so it has to have some sort of effect." Shipgirls were born from lingering feelings, after all. It only made sense that the lingering influence of the ones that had once created this world only hung around to be exploited by somebody like him.

The short girl grabbed the artifact from his hands as she looked at it. It was big and red and it definitely radiated some sort of power. Not only that, but just looking at it... It was almost as big as one of Iowa's tits! Well, before she started getting all milky, but it was still a good benchmark to put it up against.

"So this is going to make me bigger?" Ryuujou said, just making sure that she understood exactly what it was supposed to do. And as her Admiral nodded, she quickly put a string through it, one that was strong enough to handle the weight of the red-hued trinket, before wrapping that string around her neck and wearing it like a necklace. "Then it better work quick because otherwise I'm going to-"

*WOOMP*

Ryuujou let out a quick squeal as her breasts exploded forward. It happened in an instant, letting her barely witness her flat chest turning into two milky mounds that were quickly swallowing the magatama within them. Not only that, but the sheer weight was enough to make her lose her balance, causing her to tip forward and collapse onto both of them as a bit of milk spewed out from her nipples.

It felt... Oh god it felt good. It was as effective as her Admiral had claimed it to be. But at the same time, it was only really effective on her breasts. As much as she was envious of Iowa and her excessive udders, she also wanted to be just as big as Mutsu and the others because otherwise she would look completely ridiculous. And she did look ridiculous as she idly wiggled back and forth on top of those massive mounts, especially as she had to let out moan after moan because it all felt way too good..!

The magatama stuck in between her tits started glowing the more she wished to be bigger in every single way, causing her moans to turn from low pitched to nice and deep and mature in the span of a few minutes, all while the rest of her body started growing appropriately. From her legs lengthening until she could stand taller than the rest, to her arms getting longer and sleeker so they could bring emphasis to anything else, to her hair... staying the same size because part of her natural charm was still her adorably short hair and the girly pigtails she had.

By the time that her growth finished, Ryuujou could lift herself off the ground with ease because her tits weren't weighing her down any longer. In fact, she felt... Oh, she felt amazing. She felt like she could do anything at this point. Beat down an army of Abyssals? Compete against Iowa in a milking contest? Take Nagato and Yamato's respective positions in the naval hierarchy? Anything was possible for her! She was a proper adult now, and she had the body to prove it!

Atlas clapped with a smile on his face. Truth be told, he had not expected it to work as well as it did. But it had absolutely worked. And he could reap the benefits of his 'generosity', all he had to do was nudge her a little. "So, how do you feel, Ryuujou?" He asked, walking over before digging his fingers into her awfully exposed thigh. Because despite how she had grown, her clothes definitely hadn't. It was even trying to desperately hide away the naughty bits, but it was difficult considering how thick her holes were and how big her nipples had gotten. She was basically naked after turning into such a beautiful adult...

Ryuujou let out a sharp moan as she felt his fingers. And the magatama inside her cleavage started to glow a bit more. What was this feeling? It... It made her feel really hot below. "I... W-Well, it's great being big for once! Thanks, Admiral!" She cried out as she tried to assert herself, hoping that he wouldn't notice the fact that she was already starting to leak horribly from her pussy.

Unfortunately, he had noticed. And he made her aware of how he had seen by rubbing his fingers up against her plump lips. "You're big down here as well, you know. Why don't we take these virgin lips for a spin? You wouldn't want to be outbred by Iowa, would you?"

O-Outbred by Iowa. It was something that she had never really thought about. Because she wasn't really thinking about what breeding was like. But the more that thought bounced around inside her head, the more her heart beat faster and faster. She... She didn't really want to be bred, did she? The thought was...

Atlas could smell her getting more excited and how quickly the idea of being bred was getting cemented in her mind as the right idea. It certainly helped that a lot of the deities that he had communed with were fertility oriented, which meant that a ton of them were more than happy to lend a bit of their power to make sure that somebody ended up fertile. And that was all the more apparent as the faint outline of her throbbing ovaries became visible against her stomach.

So instead of letting her worry too much about the fact that she wanted to be filled with as much of his seed as she could possibly muster, he helped her onto her side and let her rest there, while keeping his arms firmly wrapped around one of her thighs so he had control over her posture. All so his crotch could rest against her drooling lower lips, which were practically begging to be fucked.

As Ryuujou was forced to the ground, all she could do was look towards the boy that had claimed her. Her Admiral. Just looking at him was enough to make her pussy leak even harder, prompting her to gasp and pant as she stretched her leg up ever so slightly despite the fact that he held onto it. All so those lips could part.

She didn't need to say anything to make it clear that she wanted him. That bratty girl who wanted everything had now become adorably docile as she was overwhelmed by her newfound need to breed. Especially as she felt her pussy being penetrated for the very first time, her body trembling all over as she felt the sparks of pleasure pouring through every little inch of her body.

Atlas, using the grip he had on her leg, was ramming into her virgin lips with a brisk rhythm. It was actually surprisingly easy to fuck her. Probably because of how she had been overdosed on blessings. But did that stop him from enjoying just how good it felt? Of course not. He was savoring every last moment of it. Savoring just how wonderful it felt to indulge himself like this. Iowa had been a good lay, especially due to the milk pouring from her tits, but there was just something perfect about these lips that made Ryuujou an even better fuck.

Moans whirled around them as Atlas kept pushing deeper and deeper into her. He wasn't just going deeper either, he was ramming faster and harder, because that hole was way too irresistible. Maybe he had gone a bit overboard with all the blessings he had enabled her to absorb. Maybe he was starting to be overwhelmed a bit. But when he thought he was starting to submit, he paid that submissive feeling back by ramming even harder and making sure that he could overpower it completely. He wasn't about to give up just beecause a hole was so perfect that he was practically being swallowed by it!

Ryuujou let out more and more moans as he practically jackhammered into her. This was her very first time being fucked, and it was going to be hard to forget just how wonderful it felt. She wanted nothing more than for it to keep going. Or barring that, she wanted to learn just how it was going to feel to indulge these desires in every other possible way. This had been the perfect way to take her new body for a test drive, and she was just craving more and more and more!

So much more that even when they both started to release their orgasmic cries, and as she felt her womb getting its very first taste of the boy's stickiest semen that was going to make sure her body was getting as pregnant as it possibly could get, she still wanted more. In fact, she wasn't about to let Atlas go any time soon, her lower lips wrapping around his rod and squeezing tightly as her eyes started to glow just as red as the magatama that had helped her mature.

Atlas looked down at her eyes, before chuckling a little. Even though he had just inseminated her once, he could still keep going. And besides, he had to make absolutely sure that he had claimed her properly. Why not do so by fucking her until they were both spent beyond belief.

Ryuujou's room quickly filled with more and more moans, only interspersed by the screams and goopy sounds of more cum being poured into the newly matured girl's womb. A process that repeated again and again, to the point where Iowa eventually ended up watching the two go at it until it was her turn again. And even then it didn't end, because those two had much more stamina than either would have imagined.

By the end of it all, and after Ryuujou had been filled with so much cum that she couldn't move an inch... There were only two that were left to claim. After he had finished breeding Iowa once more for being such a good voyeur...

Next... Was the Abyssal...

---

Seaport Princess was naturally wary of anybody that came near. Because she had heard much about Humans. Especially the ones that had originally inspired hatred within her and her kin. But after arriving at this base, she had started to show doubts. Were they really that bad? Or was the only reason her kin were so afraid and hateful towards them... The fact that they were individuals, where the Abyssals were more of a school of like minded sea creatures, so to speak?

"You want to learn more about us?" Atlas asked, after the Princess had done the difficult task of getting ahold of him. Since she was technically a captive, and she was still plenty dangerous, he shouldn't be visiting her at any point. Not until they were in more direct contact with any other base. Something that he distinctly ignored once he finally heard that she wanted to meet him.

Seaport Princess nodded, her body towering over the boy as she was about four times as big as him. Just looking down at him, she couldn't quite fathom why he would be one of their commanding leaders. Much less one that had managed to turn both the angry boat and the American boat into his loving wives. That was also one of the things that had filled her with curiosity.

"Well, if you want to learn more about us, why don't we make you one of us?" Atlas chimed with a smile on his face, as he pulled out a collar. "I wanted to give this to Iowa, to try and bring out some of her better aspects while making her more human, but the boys in R&D tell me that it can work very well on Abyssals too. You want to try it?" He asked, offering the collar and showing the cute heart hanging from it like some sort of additional accessory...

Seaport didn't understand what the little Admiral was saying, but she did reach out and grab the collar from his hands. Just looking at it was enough to make her simple brain slowly start steaming. This was supposed to make her more human? As far as she had heard from her fellow Abyssals, it was more meant to be some sort of... Degrading accessory that showed how the one wearing it was below others. And yet, he didn't offer it with any form of malice. Had she been wrong?

That being said, it was a little small. But since she wanted to understand the world around her, at least until she was able to get in contact with her fellow Abyssals. Maybe then she could come to some sort of understanding with both her kin, and these strange humans.

Seaport Princess... Fiddled with the collar for a bit because her claws were far too large to properly adjust it and fit it around her neck. So much so that Atlas eventually just let out a bit of a laugh before motioning for her to help him up, something she sheepishly did, letting him rest on one of her shoulders for the time being once she had lifted him up.

"You really are cute, you know? I don't know why the rest of the navy wants to deal with you and your kin, when you're clearly just trying to find your place in the world." Atlas chimed as he snapped the collar onto Seaport Princess' neck, watching as the heart that was dangling from it slowly started to glow. And before he'd cause any kind of trouble by being on her shoulder, he quickly started sliding down her body so he could get a good look at what happened next.

Seaport let out a brief and potent gasp as her skin started to gain depth and color. Going from being an incredibly pale lady to one that looked like she was actually alive. It wasn't just her skin either, her hair quickly turned black as it seemed like she became attuned with the humanity inside that heart...

Once she looked like she was a living and breathing human, the Abyssal was forced to let out yet another gasp as she very quickly started to shrink. It was like she had been cut down to size rather rapidly, with all of that size having to go somewhere. Because as it turned out, being turned into a human that had to inherit all of the traits that she had while being an Abyssal...

Meant that she ended up looking like the complete opposite when compared to her previous self. Instead of being tall, she was now unfathomably short. Though that was the main opposing difference, as her assets were still beyond large. In fact, they were even larger since all of that size had to go somewhere. Whether it was her outfit being forced further up her body thanks to her hips having grown so wide that she could take up a couch all by herself, or her tits practically bursting right through the fabric as they had practically tripled in size. Despite the fact that she was now the rough height of the boy that served as an Admiral, she was at least a good three times as wide thanks to all these compressed curves.

Atlas laughed a little as he looked at the newly converted Seaport Princess. Sure, he was painfully erect when he looked at her, but the way that she had gone from a tall and vaguely intimidating presence to an adorably tiny shortstack was... Well, it certainly gave him some form of entertainment. Especially as he started to drool a bit and feel a certain need throbbing through him. God, just looking at her was making him grow even more erect, his pants already sounding like they were ready to tear themselves off...

He couldn't hold himself back. Just like he had done with his other claimed ships, he pushed the short stack onto her back, something that was a lot easier considering how she hadn't yet gotten used to her size or her changed center of gravity. But at least she was still durable, something that stopped her fall from being dangerous.

Seaport Princess blushed as she was suddenly and rather dominantly grabbed by both of her nipples, Atlas parting them to make sure that she could see him. Just looking at him like that, with his hands firmly wrapped around parts of her body, was enough to make her exposed slit grow nice and wet. Why was she feeling this way? Was this because of her newfound humanity responding to her basic instincts as an Abyssal..?

Whichever the case was, he didn't really need to hear what she thought about being human. In fact, his cheeks were far too warm and red for him to be thinking clearly. He was just incredibly turned on by seeing her like this, and the only way to alleviate it was to thrust straight into her hole. Not even his pants were going to put a stop to his need to breed this incredibly fertile female, as his thrust managed to tear a hole in the fabric when he did so.

Both of them let out powerful moans as the boy sank his cock straight into her lips, with the former Abyssal letting out more moans not long after that. She felt a powerful instinct being let loose once he started to breed her, and it was... It was definitely something she had felt before. She had once been a part of a subsect of Abyssals that were meant to allow for their kin to proliferate, so she wasn't a stranger to reproduction. That seemed to be the reason why she was feeling this way. She had reawoken this instinct within her that was forcing her to mass produce more of her kin. And since a human female needed a human male to reproduce in great numbers..!

Atlas felt the former Abyssal wrapping her legs around his waist. And he responded in kind by squeezing her nipples even harder. Those large, engorged things made for great handlebars when he wanted to truly thrust with everything he had. He could feel the juices splashing against his crotch when he slammed into her. It was the kind of wonderful feeling that he just had to savor.

It was honestly a surprise that she had turned out to be such a fantastic fuck. Truth be told, the collar that he snapped around her neck was just supposed to send somebody into heat. But it seemed like the Abyssal had completely internalized what she had been told. Which was why she had turned into this short and incredibly stacked beauty. God, it felt so good to ram his cock into her. It was like he was burying it within the softest pillows known to man.

Their pleasure-filled moment just continued as the seconds ticked by. Moment after moment punctuated by their mutual moans and the wet sound of his cock slamming straight into her hole. Neither of them really needed to say anything, because their bodies did all the talking for them. Even as their eyes were locked on one another, crimson eyes looking into equally crimson eyes, they didn't say a thing. Because they totally understood what the other wanted.

Atlas wanted somebody to breed. He hadn't yet gotten enough girls to breed. Iowa, Kaga, Ryuujou, they were all wonderful ones that he was happy to breed. But he needed variety. And Seaport Princess was that kind of variety. The tiniest of the lot, but the kind that he could sink days into breeding until she was left just as wasted as he was. And that was all told just through his gaze and his actions, especially as he dug his hands into the actual meat of those massive breasts once he got closer and closer to his climax.

Seaport Princess wanted to be bred. More than that, she wanted to satisfy her inner urge to start reproducing. It was in her genetic code thanks to what she had gone through. And if she had the chance, she would happily induct any other Abyssal that had been just like her. Because being human, being bred by somebody that wanted to claim her and wanted to make her just another hole to breed... There was something so primally enjoyable about that she couldn't go against it, even if she had the mind to try and fight back. She just enjoyed it from the depths of her new human heart..!

As the two reached a complete and mutual understanding through nothing but fucking, their cries became more and more intertwined until Atlas did what he did best. He slammed as deep into his partner as he possibly could before brute forcing his way into her womb and letting the full contents of his balls pour on out, flooding that tiny chamber within mere seconds. He had fulfilled his half of what he wanted to do, as he laid claim to the former Abyssal by breeding her to the point where she would be guaranteed a pregnancy.

But did that mean they were done? No, of course not. Despite the fact that she should be tuckered out, Seaport Princess just stared straight into her new mate's eyes. And tightened her grip on his waist ever slightly. She still needed to understand what he was trying to do. Not just why he wanted to claim everyone, but what would happen once he had inseminated everyone to the point where they would be guaranteed a life with his future children.

He obliged. Because why wouldn't he? She deserved to know as much as the others did. And besides... He really did want to make sure that he had fucked her until she couldn't stand. Just because of how good it felt to fuck somebody like her.

Finally, only one would remain once he finished mating with the former Abyssal...

"You look very displeased, Mutsu. What's the matter? Don't you enjoy how much everyone gets along?"

"Not when it's because you've bred them into complacency! I had accepted our transfer, thinking that you had no ulterior motives. But here I am, with two friends and a former captive acting completely out of it, and with their bellies completely and utterly filled with cum!"

"I must ask how you didn't see that coming, I had Kaga flanking my speedboat when I came by to pick you all up."

Atlas smiled a little as he looked towards the brunette that stood in front of his desk. Mutsu, the last of the four that he wanted to claim. And as it turned out, she was the one that decided to put up the most resistance. Because she had noticed what had happened to all the others, and she didn't think kindly of it.

"I just thought you had been passionate with your secretary! Even our old Admiral did that, he eagerly showed off how passionate and how loving he was towards Nagato. That doesn't mean you can just claim us like we're supposed to be your secretaries!" Mutsu cried out, slamming her hands against the desk as she glared straight into the youth's eyes. "Are you really a naval officer, or are you just an imposter that tricked us?"

Atlas giggled a little, the fury of a woman scorned was just... Oh, it tickled him pink. "Tricked you would be an understatement." The boy said as he took off his admiral's cap, idly tossing it into the air before catching it by the rim and showing off a sigil plastered on the inner side. The same kind of sigil that had been found on the emblem on the front of the cap. "I'm a naval officer. It's just that I belong to my own private navy. And I decided that it'd be best if I relieved you of your original stations, because I wouldn't want to see you all throwing your lives away in a pointless fight against something that you wouldn't be able to defeat."

Mutsu trembled a bit as he heard that. "What are you implying..?" She muttered, her eyes firmly locked on him as he kept talking. What... Were they throwing their lives away? That shouldn't be right, they had managed to defeat Seaport Princess all on their own. If they just kept that up, they'd be able to win the war eventually.

"I'm implying that your superiors knew what they were doing when they sent you off. Not only that, but after I had some... Intimate time with Seaport, I found out that there's no real way to defeat them. Because once they start reaching lower numbers, they start to explosively breed. The moment you think you have them on the back foot is when you start being assaulted by even greater enemies than ever before. And then any momentum that you've built up won't matter." Atlas explained as he slowly got up from his chair, stretching ever slightly as he walked around the desk.

Mutsu just watched him, her heart smashing against her chest. No, that shouldn't be right. They believed in them. That was why they had sent them out to scout. All of this was just an accident, there's no way that they could've known that they'd encounter Seaport Princess at that exact spot. There's absolutely no way. And yet if she were to try and acknowledge what Atlas was saying as truth, then...

"There's another thing, Mutsu." Atlas said with a smile on his devious little face. "If you really wanted to stop me from breeding your friends, you had all the opportunity in the world. All of the phones in this base are connected to the rest of the world. If you just bothered to try and call your Admiral, you would be able to unravel this entire plot of mine. And yet you never did. Why is that?" He had already pointed out that they had basically tossed them to the proverbial sharks, and now he wanted to add fuel to the fire by gaslighting her...

Mutsu remained quiet as she heard that. She... She really could've stopped it all. If anything, she now just felt guilt over it all. She allowed everyone else to end up like that, and... Why didn't she do anything to stop it? It was hard to truly tell why, especially as she just started to ruminate on the terrible act.

Atlas chuckled. He had truly thrown her for a loop. "Finally, I wanted to ask you something." He said as he suddenly grabbed ahold of her outfit, which she had painstakingly been able to reacquire thanks to a couple of favors around the base, before ripping it apart... And revealing the sling bikini that he had gifted her the moment they arrived at the base. "If you've been trying to stop all of this, trying to get them to stop fucking me... Why were you still wearing the gift I gave you, if not because you were just envious?"

...That had to be it. That had to be the reason why she hadn't done anything. Because she had been worried that she wouldn't get her chance to have fun with him. She wanted to be bred just like the others. She just didn't want to admit it because she was still attached to the mission that they had been on. But just hearing him point out her flaws, point out that all of this had practically resulted in them playing along to the tune of their former masters... It was liberating. So much so that she took a deep breath, and slowly but surely started to kneel down completely until she was prostrating in front of her new Admiral...

Atlas raised an eyebrow, before chuckling a bit. He kneeled down and slowly lifted Mutsu's head back up. "You don't need to apologize, Mutsu. You just did what you thought was right. Even if that wasn't exactly the best thing you could've done." He was quick to forgive her for her misgivings. Even if he had been the cause of a lot of them crowding inside her mind. "But if you'd like, we can deal with that jealousy. Right here, right now."

Mutsu slowly looked into her Admiral's eyes. "Admiral Atlas, I..." She paused, before shaking her head and drawing a deep breath. No, she shouldn't be worried anymore. Without just confronting her faults, she wouldn't be able to move on. So she smiled, from ear to ear, as she shifted from her knees onto her back instead, spreading those legs as far apart as possible. "Admiral, please. Inseminate me, just like you've done to the others."

"You always had the most level head out of the three. But since you asked nicely, and since you seem like you've made up with your problems, I should reward you." Atlas said as he grabbed ahold of those spread legs, pushing them up ever slightly so they were pressed up against his ship girl's body and allowing him to press down on her at the same time... Before flexing his legs slightly to force his pants off his body and then slam straight into her hole.

When he thrust into her, he slammed right past the sling that had been covering it. Snapping it in the process, letting Mutsu's breasts bounce all over the place thanks to how violently they had been freed from their tight prison. The violent bouncing was only emphasized as she started to let out loud cries, both from the fabric snapping against her most sensitive spots, and the way that he had already begun to breed her with such intensity that she wondered how any of the other three had managed to endure any of it. And how they had managed to go for several rounds on top of that!

Still, she wouldn't be outdone. Despite the fact he was pressing into her with a lot more intensity than she could’ve anticipated, she would try her best to endure. Even as she felt her arousal climbing and her breasts bouncing more and more as he kept being so overly aggressive, she didn't go past the point where she'd be forced to orgasm. She held out, even as she looked straight into his eyes.

There was something so adorable about the way that Mutsu was holding out. Atlas couldn't help but chuckle a bit as he looked at her. He wanted to wipe that look off her face. Not by breaking her, far from it, but by seeing it melt in response to how he treated her. And the first way to do so was to lean over her and plant a kiss straight on her lips, to see how she would react.

Mutsu's face quickly got swallowed by an incredibly deep shade of red. So much so that she couldn't possibly hold back against the sheer amount of pleasure pouring through her. She could feel it all. It was so amazing. She wanted nothing more than for it all to continue. Why had she tried to stop all of this, again? Because she wanted to make sure the others were okay..? She didn't understand what that concept was. Because it felt too good to be rammed into...

It didn't take long after she had lost control of her own arousal before she started to climax, her lower lips wrapping around her Admiral's cock as she tried to wring him dry. This was something that her body did all on its own. Because it had quickly picked up on how it should be servicing somebody like him. How it should be able to handle him. Which was quite impressive, considering how against this kind of intimate contact she had been just a few minutes prior. She had turned into a bonafide breeder with this little push, and seeing it was enough to make her Admiral grin.

As he felt her folds trying to wring the cum out of him, Atlas gave her the same kind of treatment that he had given the Abyssal as well as the other two shipgirls. He rammed straight into her and opened up her womb with that same thrust, before letting loose an almost primal cry as he unloaded the contents of his balls straight into that tight hole, filling it and quickly inflating her stomach in the same motion. He had gotten used to this after doing it so often. Whether it was to the three that he had claimed over the last little while, or Kaga who had been his proverbial sparring partner when he was still just starting out.

Speaking of that secretary of his, he'd have to move forward with the final part of his plan. And that would require him to pull out of the girl that he had just inseminated, taking a deep breath as he reached into the singular pocket on his uniform. Pulling out a beautiful looking ring that seemed to reflect any light that poured onto it. It was even on the verge of blinding him when he held it this close to him. "Mutsu. Be mine. Not just as an Admiral, or as the one that impregnated you. Be my wife. I will take care of you, just like I've taken care of the others."

Mutsu dwelled on this sudden development for a few seconds before holding her hand out. "Of course, Atlas." She said, panting and blushing a bit because she was still far too turned on after her last orgasm. And the fact that she had so much breeding batter bubbling around inside her womb, waiting to develop into good little kids once it had properly settled.

Atlas smiled as he slid the ring on Mutsu's finger... And confirmed that he had claimed the last of the four that had arrived at his Base thanks to his impeccable timing.

It wouldn't be long before the fruits of claiming them would make themselves apparent...

"Admiral. It's time."

Atlas smiled as he was greeted by one of his dearest and most loyal wives. The Secretary that had helped him set all of this up, Kaga. Even now, after nine long months of her being at his side, she was still as beautiful as ever. Even if that grossly gravid belly that was stuffed full of a dozen or so kids was starting to reach down towards the floor. Not that it mattered much to her, she was still as stoic as ever.

"Good to hear. You've helped them get ready?" He asked, with his secretary nodding softly. "Great. Let them in. And then go relax, you're due any day now. I don't want my precious secretary to end up troubled when she's this close to her special day." Atlas chimed, giggling a little as he saw the blush developing on Kaga's cheeks.

Kaga gently bowed as she took her leave, not planning on going against her Admiral's orders when he was very clearly looking out for her. Especially when he still had something else that he definitely needed to enjoy. Something that he had been working hard on over the last two months.

That something made its way into his room not long after his Secretary had started to leave, as one by one four familiar looking women took their place inside his office. Each of them wore expressions that were a mixture of happy and either excited or nervous, depending on the girl in question.

And it was very easy to tell why they were all like this. Because every single one of those wonderful girls had shown up wearing the exact same kind of garb. Erotic wedding wear that was combined with equally erotic maternity wear, leaving them decked out in white latex with cloth bringing attention to their more intimate areas, while some of that latex managed to cup their bellies in particular and bring extra emphasis to them...

Of course it also really just emphasized how much each of them had been bred. Especially thanks to the extra 'rings' that had been added once they had grown this big. Iowa in particular had been decked out in a lot of these extra accessories, because as an American she wanted to stand out as much as she possibly could. Whether it was getting cute wedding rings pierced through her nipples, pierced through her outward belly button, or simply just adorning both of her ring fingers. She wanted to let anybody that looked at her know that she had been married to a boy that loved her lots and paid her love back with an incredible amount of intimate breeding.

Ryuujou wasn't far behind in that department, though her wedding dress was more emphasized on her mature figure. Whether it was her incredibly wide and made-for-breeding hips, or her equally astonishingly heavy tits. She wanted somebody, her dear hubby in particular, to dig in and make sure that they could hold on when they were breeding her. That's what mattered to her most of all. That, and showing off her mature and totally bred belly. That was another part of her that she really liked, and it was all thanks to the boy that had given her that magatama.

The idea of being wed was something that Seaport Princess had to get used to. Especially since the equivalent attire barely fit her due to the way she had been compressed. But she managed, even if the latex was struggling to avoid ripping and tearing with every breath she drew. It certainly didn't help that her pregnancy was making her look even more stacked than usual, to the point where you could probably roll her around like a ball. And yet despite the fact that she looked like this, she maintained a smile as she looked at the human who she considered a husband, a kindred spirit... And a mate for life, considering how intimate they had been.

Finally, Mutsu was wearing her outfit with a lot of pride considering how she had treated her Admiral just a few days prior. She was rather surprised to find out that the true effects of that wedding ring involved accelerating the pregnancy she had just been saddled with until it was as ripe as the rest of her fellow girls, but she had come to accept it rather quickly. Mostly because there was something primal stirring inside her as she let the heft of that belly nearly weigh her down. It gave her a new sense of responsibility, just like she had when she was back with her old Admiral. But this time she didn't need to worry about any tricks, because Atlas was truly honest with them at this point...

Atlas just sighed as he looked at all his ships... His wives. He had done a lot to make sure that all of this came to pass. Whether the old base had realized that he had tricked them and managed to take their ships into his personal employ and care... He didn't really care at this point. What he cared for were those four that were gathered for him and him alone.

"I think you all know what you need to do?" He said, climbing out of his chair and onto his desk, letting his pants fall off before he managed to climb onto the wooden surface so his cock wouldn't need to be trapped inside any kind of prison. He just let it sit there, the faint smell wafting off it as he smiled.

All four of his wives nodded, each of them looking positively ravenous when faced with this cock, before letting it get trapped in the tiny space between their massive bellies. A place that Atlas had been wanting to experience for a long time...

And once they were done making him feel good with their bodies, it was time for the first of their many intimate fucks throughout the day. The mark of their brand new daily routine, as one of his wives. That was how their lives were going to go from this point on. Meeting him in the morning, helping him cum with their bellies, and then being bred all over again.

As the light quietly reflected off their many rings, they truly couldn't be happier. He had managed to fill their lives with so much happiness. Even if he had come out of nowhere.

But Atlas? Oh, he still wanted more. Even as he let loose on their bellies, covering them all in his sticky seed. He was still craving more cuties in his gravid fleet...

Kaga would have to help him scout out new girls to steal away... Once he finished having fun with all of his current wives.
