[Weight Gain, Immobility]

Ayanami Rei was in a situation that she could best describe as peculiar. Because she was sitting in the middle of a western style room that was much more pristine than the room she had back in Tokyo-3, and the circumstances behind her transfer to this room were just as peculiar as the situation itself.

A length discussion had gone on between the people that served as her commanding officers and a strange young man who served as a source of additional funding. And to appease him and ensure that they would get everything they needed to fight back against the Angels, she was sent out to a brand new facility.

"Do you like your new home, Ayanami?" A soft voice echoed across the speakers, before the owner of the voice cleared her throat. "Nah, scratch that. How are you actually feeling, Rei? Don't worry, you're not being recorded. I want your honest feelings. It's not often that I get to keep an eye on a girl like you."

As far as Rei could tell, the owner of this voice was a woman by the name of Byakko. They had seen each other exactly once, but the sight of her only added to the blue-haired chosen child's confusion. She was shorter than Rei was, and she had a set of catty features that made her seem more like some form of nascent angel than anything else. How else could one explain those features? Well, considering she hadn't yet been apprehended or anything, it didn't seem to be anything that she needed to bring up.

"I am... Fine." Rei replied as she slowly looked around the home. It really didn't fit somebody like her. Who just left her room to carry out her missions and not much else. "Byakko. What is the purpose of me being here?" While she didn't explicitly have permission to ask questions like these, she needed to know.

Byakko could be heard grumbling a bit in response to the question. "I'm not supposed to let you know, but... Essentially, you'll be staying with us for the duration of an experiment. I'm in charge of keeping an eye on you during that time. Beyond that, you don't really have any obligations besides stay in your room and keep healthy." She explained, the sound of her hair being audibly ruffled echoing over the communications system. She wasn't the best fit for this kind of task, was she..?

Still, it was conforting to have some sort of knowledge of why she was here. Though that didn't explain why she had been made to dress in her plugsuit. Was this just for convenience, or was there an ulterior purpose to it all..?

*Growl*

That sound would happen to be her stomach. It had been a good deal of time since she last ate. Then again, since she was bedbound for a majority of her day, it didn't strike her as odd that she found herself rather hungry at this very moment.

In response to her stomach letting out such an obvious growl, a tube slowly started to sink down from the ceiling, right before it stopped in front of her mouth. Which happened to make the chosen child raise her eye. What was this for, exactly? Was this for her? It seemed rather crude all things considered...

"Sorry about that." Byakko could be heard over comms once more. "This room's also designed to keep you well fed and make sure that all of your needs are looked after. But the last time we made a room like this, it went a bit overboard. So we scaled back the functions for the time being, and instead of cooking up elaborate meals, it will instead merely deploy a nutritious paste that will keep you from getting hungry. Hope that's alright, I wish we could've ironed out the kinks first."

Rei nodded a bit. "It's alright. This is fine." She muttered softly. If this was the way that she would get fed, it would have to do. It's not like she had a choice in the matter, and it would probably be better than laying on the bed getting injections every day instead.

She stuffed the tube into her mouth, and the system that controlled the tube registered her lips. Slowly but surely, a thick paste poured down through the tube and straight into her throat. It was a little sudden, to the point where she was on the verge of breaking away thanks to how it blocked her up...

But then it plopped right into her stomach. And the flavor practically exploded through her. This was supposed to be the emergency measure? If that was the case, then she couldn't possibly imagine what the true dishes would be like, should Byakko have managed to get everything working on time. Without hesitating any further after having a taste of that, she swallowed as much as she was allowed to swallow, determined to put an end to her hunger...

The flow stopped not long after that, and the tube quietly retreated into the ceiling. Leaving the thoroughly filled Rei with an oversized tummy that was just sloshing with all that delicious slop she had just swallowed. She couldn't honestly believe it. One moment she had started to drink all of it, and the next she had grown this big? Was that really supposed to happen, or...

"Seems like you enjoyed the automatic feeding system. Don't worry, you won't have to actively stuff the tube into your mouth in the future. I just wanted to let you take it for a spin on your own terms before we made it too automatic." Byakko explained across the comms, before laughing a bit. "Still, you were out for a few minutes there! You've had a bigger drink than anybody else that's used the system. No wonder you've been chosen by NERV, if this is the kind of gluttony that you're working with!" The rather loud and excited kitty was enjoying the sight a lot. And though her words were rough, it didn't seem like she intended for them to be harmful.

Rei trembled a bit as she looked down at her stomach, watching it groan a bit more... Before the tube descended from the ceiling yet again. But that wasn't hunger, so why did it-

The tube shot into her mouth, and her eyes slowly started to glaze over as she got another taste of that wonderful liquid...

"Day 31. Goodness, you've gotten quite big, haven't you, Rei?"

There was no response from the light-blue haired girl. Besides the endless groan from her stomach, and the sound of her food rushing down its tube. A sound that both the girl and her handler had grown quite used to. Because it was one of the few sounds that ever echoed through this incredibly cramped room.

NERV had certainly fulfilled their half of the bargain. They had given Atlas Corp a test subject with Angel blood that was utterly disposable to them. And in turn, Atlas Corp had provided all the funding that they requested. But was this really what was intended? For the test subject to end up filling up a room all by herself, sustained on nothing but a flavorless slop?

It wasn't a glamorous life. It wasn't an enjoyable life. But it was definitely a life. And given the lack of adverse reaction that Rei had to everything that happened to her, whether it was her body stretching further and further to the point where she almost outgrew her plugsuit, or her portions growing bigger and having an intense effect on the weight her body gained. Nothing really made her react with anger or disgust or anything. She was just accepting this as natural developments in her pursuit of the command she had been given.

Byakko wasn't exactly displeased with it either. It was... interesting to see somebody like Rei slowly but surely balloon out into a blob that couldn't move without much help. Not that she needed to move. The room, which had long since been simplified to account for the girl's continued growth and her excess weight, was the only place that she needed. It was her home and her world, and as long as she was kept well fed, she wouldn't have a problem with being stuck in there for hours upon hours on end...

"Still no response. Oh well. I didn't expect to hear anything from you, blubberbutt." Byakko chimed as she tapped a few keys on her keyboard, the keystrokes echoing over the comms but they didn't cause the girl to react. Because she had heard them so many times that they sounded more like background noise to her.

Once the keystrokes came to an end, there were three more tubes that started to extend out from the walls. Two of them latched onto the plugsuit that was still doing its best to stay intact, but more specifically the oversized girl's breasts. And it didn't take long after that for the tubes to sink straight into Rei's breasts, causing her to let out an incredibly soft moan that echoed out around the tube in her mouth.

The final tube, once the others had been firmly fastened to her udders, sank into the crevice hidden on the mountain that was her stomach. It sank as deep into her belly as it possibly could, just to make sure that there was something stuffed into the most sensitive spot on the girl's body. And once it had gone all the way inside and was ready to be used...

it started to vibrate and ram up against the walls of that incredibly deep belly button. Causing pleasure upon pleasure to pour through the enormous girl, sending ripples upon rupples across her belly as all of that brand new arousal forced her to climb high and higher up the proverbial ladder.

Until Rei let out a delighted scream of pleasure, mostly muffled thanks to the tube inside her mouth, and then started squirting from every hole. Mostly her udders, which started leaking so much milk that she would've started making a puddle of the stuff if not for the tubes that were currently slurping up all the milk...

This was the true purpose of her stay here in this self-sustaining room. Once she was sufficiently fattened up, the formula would allow for her body to produce milk. And this milk was more valuable than she ever could've imagined. After all, it was full of angel genes. What could humanity achieve with this kind of mass production? Of course, she wasn't hardly the only cow that was going to milked, because Atlas Corp wanted much more than just angel milk.

Byakko though, she had a real soft spot for this cow. She specifically made sure that the slop that was being fed to her was delicious in just the right way. Partly to apologize for the way that she had been left in an incomplete version of the self-sustaining room. Partly because she just enjoyed watching the way she grew. The others had grown far too quickly for her liking. Rei... Rei had taken this long before she filled out hte room, when others had taken a week or so. It proved that she was more resilient, and it made the entire experience that much more entertaining.

"That's it, Rei. Just let it all pump out. My favorite blubbercow." Byakko sighed in satisfaction, a little trail of delight running down her thigh and down her chair as she watched Rei having her tits pumped and her milk drained. All while her bellybutton was being molested by that elongated tube. It was such an absurd sight out of context, but to her, it was the greatest kind of entertainment that somebody could want. She wouldn't want anything else.

And though Rei couldn't really perceive anything else thanks to how much she had been eating and how little she could move... She was enjoying this too. It felt nice to be milked. It felt nice to be fed.

If this was her duty for all eternity... Then she'd be happy knowing she was milked and fed.
