[Nerd TF, Weight Gain]

"Ah! Warspite! Do you mind-"

Just as quickly as she had called out to her, the royal girl had disappeared back into her room. Where she had shut herself away over the last few weeks. It was something that had brought a lot of worry onto the shoulders of the girls that served the fleet, but especially her fellow westerner. It was hard enough getting chummy with all the different Japanese girls, but it was even harder because she thought she had done something wrong.

Iowa, the American girl herself, let out a sigh as she went right back to her room. If she couldn't get ahold of Warspite physically, then she'd try and contact her through the internet. She really had to thank their Admiral at some point for the addition of personal computers within each and every room. It allowed her, as well as any of the other girls, to chat with the humans they had grown close to. And in the case of her and Warspite, it meant that they could talk with their countrymen back home...

But more importantly, it allowed her to chat with Warspite! All she had to do was invite her to a... Hold on, what was that? It looked like Warspite was playing some sort of game that she had never heard of...

"Mamono Collection?" Iowa tilted her head. As far as she knew, based on her vague understanding of Japanese as a language, Mamono roughly meant Monster. Somebody was collecting monsters? Was that like that Pokémon thing that had swept her home nation? Whatever it was, she had to go investigate. And then maybe she could catch her with a conversation about it. Maybe she was just a nerd or something. Yeah, that was probably why she wanted to keep herself locked up. So she didn't expose her true nature to the world. It would be an embarrassment to her namesake...

Iowa tapped around a bit and found the download page for the game, quickly letting it transfer onto her computer. All while stretching and chuckling. Okay, maybe Warspite had been scared off by how sweaty she was. Maybe she should've showered after her workout, instead of-

"Greetings, Master!"

Iowa's eyes widened as she looked at the game popping up in front of her. She... She was staring at a girl that looked way too much like herself. There were the stars in her eyes, the long blonde locks, the really big breasts and the almost slightly muscled physique. But the main difference between the two came in the fact that the girl on the screen definitely wasn't even close to human.

No, she was a Monster. A lamia if she had to be precise. What else would you call a girl with half of her body missing, replaced by a really long and honestly really pretty and almost patriotically red, white and blue tail? That's it, she was definitely some sort of alternative version of herself. Or at least somebody had looked at her and used her likeness without telling her.

But man, she was pretty. Super, super pretty. Iowa barely even noticed how she had started to drool at the sight of her other self, trembling a bit as she kept looking right at her. She... Could she call her Master again?

"Master, are you happy to see Iowa?" The digital serpent giggled as she looked straight ahead, as if she was staring straight into Iowa's soul. "Iowa's happy to see you too, Iowa hopes you'll take really good care of her. You know how to do that, right, Master?"

Iowa shook her head as she listened to the serpent that had wormed her way into her heart incredibly quickly, all while hearing that sweet sound of her giggling echo through her ears. It felt so nice to hear. It was like... It was like hearing herself. But it wasn't her. It was a girl that was so, so much prettier than her. She could just get lost looking at her all the time...

"You just have to pay a little. You can do that, right, Master?" The serpentine version of Iowa giggled a little more as she lifted the tip of her tail, revealing a payment button. With a rather large number already put on it. It didn't really describe what it would do, just that Iowa made it seem like it would help care for her...

Iowa didn't hesitate. Besides, the amount was a pittance compared to what she earned for her service in the fleet. As long as she could see that other Iowa smile, then she was happy. Even though she had only just met her, she felt like she had known her for long. And making her sad, or disappointing her in any way... She would never do that.

"Thank you, Master!" The serpentine Iowa giggled, twirling around as she started to glow lots. "But you have to keep working hard to take care of me. You have to be here to take care of me all the time. Look out for me, and make sure I'm nice and healthy. You'll do that, won't you, Master?"

"Of course, Iowa!" Iowa cried out, her stars turning into hearts as her heart slammed against her chest. Ahhh, just hearing her was enough to make her tremble. She wanted to give everything to her. Every little second of her time, every little hour of her life. Devoted to nothing but her and only her.

She couldn't even see the slightly smug smirk on the other side of the screen. She was completely and utterly enthralled by the sight of her. She would do anything for her. She would sell everything she owned, as long as she could spend more time with that other Iowa. She would genuinely do anything to satiate her, even if it meant just sitting in front of the screen to keep her company...

Ahhh... To be with the other version of herself, that was what Iowa had to do from now on...

---

To say that Iowa indulged after that would be an understatement. Just like saying that she became a shutin wouldn't quite capture how much she had isolated herself from the outside world.

To her, this serpentine copy of herself was her new world. Seeing her happy, seeing her smile, that was the only thing she needed. Which meant that anything else was completely and utterly optional. Which first and foremost, included taking good care of her own health. And that was most obvious as she started to toss her clothes off, not really caring about what she wore when she gamed.

The first signs of how little she cared about herself in comparison to her other self was how quickly she started growing body hair. Her armpits were completely full to the point where you could practically her pits jungles, and the bush down below had grown so thick that you could see it spreading out onto her thighs and a little further up her belly, forming a trail that pushed right above her belly button.

But her hair wasn't the main concern. No, the weight she had started to gain was. Instead of bothering to go out and join others in the mess hall, she had begun to order takeout whenever she deemed it convenient. She didn't even really have to be properly hungry. Whenever her dear Iowa wanted a meal, she ordered one. Even though she couldn't eat with her, there were options in the game that allowed her to eat. And she really felt a connection between the two of them whenever they ate together, even though she was the only one that was showing any changes.

After a few weeks of this behavior, around the same time that she had started getting extra hairy, her belly had really started to sag. To the point where it was very nearly about to reach out over her knees. And it wasn't like she was going to be too bothered by the way that it was growing either. Even though it pushed out against her armrests, it actually felt really nice. Not just because of the squeeze...

"You look really cute, Master!"

But because every time she started to feel a bit of doubt inside her heart over how much she had fallen, the serpent she had fallen in love with would cheer her up with some of her characteristic kind words. It never failed to make her feel good. Both in the sense that her heart felt nice and warm, and the way that her seat grew nice and wet every time she felt that compliment ring through her.

Of course, she couldn't just stay a slob. Not a slob that was just showing everything off, anyway. Sure, Iowa kept on calling her a cutie and a beautiful Master, but that wasn't enough. Because the game decided that she should wear something else. Something that really showed her devotion.

That was how Iowa ended up wearing a shirt depicting her favorite serpent on it. It was kinda stretched out thanks to the way it wrapped around her lower fold, which made the serpent version of Iowa look a lot thicker than she did in game, but Iowa didn't care too much. She was just happy to be wearing her. Happy to have her closer to her heart...

Of course, there were several of the other girls that were starting to grow concerned as they noticed how little Iowa got out of her room. And once they heard about her delivery, they were all forced to go and see what had happened to her.

The proud shipgirl, that many of the other girls in the fleet looked up to, was a complete mess. Whether it was all the sweat and grease that was pouring down her hairy body, whether it was the overly stretched shirt that had soaked in all of the juices that were either pouring from her body or splattering onto her from her food. Or it was the way that she had left a massive stain on the floor, courtesy of all the times that hearing her other self had made her cum. Or simply the tacky glasses that she needed to see the screen in front of her, showing just how much her skills had degraded...

Not that she cared about what they thought. She only cared about her Iowa. She only cared about that blonde snake that had continuously tempted her to empty her wallet. All because of her smile. All because of how much she just wanted her to be happy. It didn't matter that she was basically just a couple of jpegs that were strung together to make a beautiful girl. She was hers. She was her very dearest Iowa.

So she simped more. Her reputation within the base was already ruined, even if she didn't care about it, so she genuinely had absolutely nothing to lose. All she had to do was just continue funneling more money towards her dear Iowa. Pulling more and more copies of her, which allowed her to gain more outfits, which in turn allowed Iowa to cum more and more. It was a never ending cycle.

It even got to the point where she had forgotten all about her original idea. The fact that she was going to play this game to bond with Warspite. That thought had completely and utterly disappeared from the recesses of her mind. Because she didn't think about anything else but her beloved Iowa.

Which was why she was surprised to find an invite inside the game, and a webcam delivered to her a mere few days after she had gotten that request. Because as it turned out, her pursuit of Iowa hadn't gone unnoticed. Because her pursuit of her eternal love shooting her to the top of the leaderboards wasn't going to stand. No, she had angered the one girl that she had originally set out to help by playing this game.

Warspite had noticed Iowa's presence. And for the sake of her dear Warspite, she was going to put an end to Iowa's simping..!

---

"No faaaair! How come your Iowa's so much stronger than my Warspite?!"

The angry and honestly pathetic whining echoed through Iowa's headset, all while she could see her opponent seething thanks to the webcam pointed at her. It was such an unbefitting look for a would-be royal girl like her, and yet here she was.

Warspite, the girl she had been chasing after, was in a state almost as bad as Iowa herself. Both in terms of how little she had been caring for her hygiene, and how fat she had gotten. In fact, she was definitely fatter than her. It was just harder to tell due to the way that her fat pushed into the squishy chair, all while the blonde would-be royal huffed and gasped and panted...

"Iowa's the best there is, that's why she beat your Warspite!" Iowa grinned, all while reaching for her snacks. A rather impossible feat, which resulted in her fingers barely being able to grab a couple of chips at a time. "Guess you'll just have to spend more to make her better, not that a cow like her could beat my serpent girlfriend! Isn't that right, Iowa!"

"You did a great job, Master!" The serpentine Iowa that was currently seductively slithering around on the screen giggled, all while slowly rubbing her belly. All while the outline of a cow-horned girl was visible inside that rather oversized tum. She had just devoured her opponent whole, leading her to finally look like she was on the verge of being as large as Iowa...

Not that Iowa was so pitifully small at this point. No, she had definitely grown. Not just because her seat was on the verge of breaking with the bottom of her fat mountains trying to reach under the back of her chair, but because of the sheer amount of rolls that were present on her body.

It was practically impossible to tell that she was wearing a shirt dedicated to her favorite, because the rolls on her body had swallowed most of the fabric whole. Not only that, but stuck underneath those very same rolls was more sweat than she had ever secreted before, as well as all the crumbs that had rolled down her body.

Beyond the ones that were currently nestled on her second chin. Due to how much she weighed down her chair, Iowa was forced to look up at her screen more often than not. But thanks to the sheer amount of fat that she had piled on, she still managed to show off her second fat chin, regardless of the generous angle. And it also served as another step where all the juices and the crumbs could get stuck.

"Master, you like what you see, right?" Not that she'd really focus on her own body. Whether it was fat or hairy, no, Iowa was only ever focused on the girl in front of her. That serpentine predator that had devoured Warspite's favorite Warspite, giving her that alluringly fat belly that was just begging to stay around. "You know what you could do to make this more permanent, right?"

Iowa didn't need to hear another word. She immediately and rapidly clicked the button that allowed her to make Iowa's figure more permanently fat like herself, because she was so beautiful. But unfortunately, she was too slow. The prompt disappeared so quickly...

And just like that, not only did Iowa's belly disappear, but the cow that she had fought reappeared as well. The cow-like Warspite that just huffed and stormed away, no doubt to complain and get comforted by her owner. Something that was already quite visible on screen, as Warspite's feed cut off right as she helplessly cried out for her dear Warspite.

"Oh dear. Sorry, Master, but I guess you'll just have to be quicker next time. But you like me like this too, don't you?" Iowa giggled as she showed off her seductive serpentine body, as well as the premium skin that adorned it. All that delightfully glammy gear that Iowa had paid top dollar to get ahold of. It made her look like a harem dancer, even if she was the single member of that very harem...

Iowa trembled as she watched her dance. It didn't matter how Iowa looked, it just mattered that she was devoted to her and her alone. Ah, watching her like this was making her drool in delight. She loved seeing it. She loved every moment of it. It made her tremble all over. She wanted her so much more than she already did. She just wanted her to be hers and hers alone, forever and ever... And if she had to keep emptying her pockets, then..!

"Oops! Sorry, Master! I need a bit of change, can you pleaaaaase pay?" Iowa suddenly stopped, and another prompt to pay an absolutely astonishing amount of cash appeared on the screen. A prompt that Iowa quickly paid, not even blinking for a second because her dear Iowa needed her.

The serpentine Iowa giggled as she blew a kiss right towards her Master. "Oh, you're so sweet, Master! I'll be back soon, okay? Just stay there and don't go anywhere. I'll be back before you know it!" She chimed, slithering into the unknown all while still giggling as much as she possibly could.

Iowa watched as her dear serpent disappeared. But she knew she'd be back. She was going to do something wonderful, and then she was going to shower her in thanks, and then she would feel all sorts of good. Indeed, just thinking about all of that was enough to make her tremble all over.

A mixture of a rather loud and degrading burp and an orgasmic scream echoed out from the blonde nerd's lips, all while the chair underneath her struggled to contain her weight. But it held out, even as it soaked in more of her disgusting juices...

Ahhh... Iowa couldn't wait for her dear Iowa's return... Then she'd spend even more on her, to make her all sorts of happy. But at the same time, she couldn’t just sit around and wait, could she? W-Well, while Iowa had told her to sit still…

With a bit of a struggle, and more gasps than she would like to admit, the blonde nerd forced herself right up onto her feet. Standing up with how much she weighed at the moment was a difficult endeavor, but it didn’t have to last long. She just had to get over to her bed, where her precious Iowa was waiting…

Oh yes. Of course she hadn’t just bought a simple shirt to show her affection. She had bought figurines, she had bought all sorts of merch, but most importantly… She had bought a body pillow. A long body pillow that reached all the way from one end to the other, and she had made sure that it was well equipped to handle her. All thanks to the massive set of schlongs that had been slapped onto the body pillow from the day that she got it. Ahhh…

Iowa lifted herself onto the bed, and then right onto the twin dicks. She could barely even let out a cry before she started cumming uncontrollably all over that body pillow. Ahhhh… Her dearest and most adorable and most beautiful girlfriend was so hung that she was on the verge of breaking her just from sliding everything into her…

“Iowaaaa… iowaaaa!” The perverted mess cried out as she just snuggled that thick pillow, squeezing it tight as she pressed her nose up against the raised armpits on the pillow. “You smell so good, you feel so good! Everything about you is so perfect!” She cried out, humping away at the pillow as much as she could. It was so, so good..!

She came. Again and again and again. Soaking her bed in juices all over again. Like she had done every day since she received that body pillow. She had indulged so badly, and it was part of why she had gotten so slovenly. But did she care? Of course not. She just loved how it all felt. She loved having fun with her Iowa. Aahhh…

“Iowaaa…” Iowa gasped and panted as she collapsed on top of her body pillow, drooling like the mess that she was at heart. The simp that she had been corrupted into, all because of a simple game. She couldn’t do much more than eat and devote herself completely to the silly snake that looked like a much more idealized and totally slim version of her. But at the end of the day, she didn’t care. Because she had her dear Iowa…

Iowa sighed and drooled right on top of that silly pillow of hers, before drifting off to dream about having her dearest girlfriend coiling around her and squeezing everything out of her…

Ahhh… What a lovely life she led…
