Oreimo WG story (Kirino) by Sveera

"Kyousuke!" Kirino pounded on the door of her brother's room.

"Kyousuke! I want my eroge back!

"That idiot" she thought. "I let him play my newest eroge, and he's still not done with it? It's already been a day!" Her continued pounding had no effect. "Tch. I guess he isn't here. Whatever, I'll just grab it from his room."

Entering her brother's room, she began her search.

"What the hell?" It's not even in his laptop? Has he even played it yet? …It's not here in his desk, either… Not in the closet… Maybe it's under his bed…"

She reached under Kyousuke's bed, dreading what else she might find.

"That pervert! He still keeps his porn magazines under the bed? …I wonder if he's still into glasses… Wait, what is this?"

Kirino paused, observing the magazine she had just uncovered.

"This girl… is this some kind of joke? She must weigh over 250 pounds!"

Opening the magazine, Kirino observed her brother's new taste in women. Page after page contained women with bulging bellies, huge breasts, and titanic asses. None of them looked to be a pound under 200. She turned to a page in which two Amazons, both garbed in nothing but traditional sumo wrestling gear, which was mainly hidden by their enormously fat bellies, which overflowed and covered their garments. The picture had been taken in a moment of collision between the two titans. Their girth was pressed against each other, breasts pressed against breasts; belly squished against belly, with their luscious fat rolls shuddering and quaking with the momentum of their impact.

The next page contained a young Japanese woman dressed in a school uniform, her back to the viewer with her head turned, looking at the camera with a teasing glance. Looking at her thin face alone, she seemed to be a beautiful 19-year old girl. However, a slight glance to the south revealed a uniform woefully inadequate to cover her massive girth— the back of her torso were barely covered by the fabric of her shirt, and her luscious, plump back, covered in soft and malleable fat, betrayed what Kirino assumed was a considerably prodigious belly. But what really made this woman unique was her ass— no, "ass" doesn't seem adequate to describe it, Kirino thought. Not at all covered by the incredibly small skirt, her massive, colossal, rear end was something else entirely, made of two enormous globes of fat pressing against her barely visible white panties. Her right hand was placed on her right cheek, grabbing a handful of the bountiful flesh that made up her heavenly derriere, kneading her colossal ass and its plump and beautiful flesh as though it was unbaked bread.

"What… What is this!?"

Kirino dropped the magazine in a panic, shoving it under the bed again, and, forgetting her search for her eroge, fled back to her room, slamming the door. She sat at the foot of her bed, breathing heavily, betraying her panic.

"Why… Why did Kyousuke have a magazine like that? …It's a joke, right? That magazine was some sort of disgusting joke, right? Who could…  who could like fat girls? That's disgusting! Such huge bellies, gigantic… boobs… big, fat asses…"

Kirino paused her frantic thinking. She tried to think calmly.

"Well… guys like big boobs, right? And… some guys like girls with bigger butts that normal… but there's a limit! A girl can be curvy, even voluptuous, but fat girls are disgusting! How could… how could my brother like those kinds of women? I always thought he liked skinnier girls… But then again, he doesn't know any bigger women… Could he really like… fat chicks?"

"And if I got fat… what would he think of me?"

******************************************************************************************

"I'm home!"

Kyousuke took off his shoes and went into the house. Noting the smell of food wafting through the house, he immediately headed to the kitchen.

"What's going on in here?"

Not unexpectedly, upon entering, he saw what had become an increasingly common event as of late: Kirino was feasting upon a meal she had just made. Obsessed with her food, she took a moment before noticing him.

"Mmph— er… welcome home."

"Hey… what did you make? It smells good."

"Wha— I didn't make this for you, idiot! I was hungry! Make your own food!" Kirino retorted angrily.

Yeah, yeah." Kousuke muttered. "I should have expected this by now", he thought. Over the last two weeks, Kirino had seemingly become quite obsessed with gorging on whatever food she could get her hands on. As she finished her meal and walked off, Kyousuke noticed that all that food seemed to be having an effect on her body. Formerly rail-skinny, as befitting a young model, Kirino's body had grown in size recently. Though it was a small gain, with Kyousuke estimating it to be about 12 pounds, her short, near-revealing clothes clearly illustrated its effect— as she walked away from him, he noticed that her incredibly short shorts now seemed to finally prove inadequate to fully cover her butt, as her swaying hips caused them to ride up the tiniest bit, displaying just a hint of her ass. Her shirt also seemed to display the smallest fraction of an inch of her slightly swollen waist.

"Hm." Kyousuke thought. "That's odd. She's always seemed so conscious about staying thin before. I wonder what's going on with her."

******************************************************************************************

"Don't you think Kirino's gotten a little… heavier lately?"

At the site of a model shoot by a pond, two photographers were discussing the changing body of one of the young models they were responsible for photographing.

"You just noticed? She's really plumped up! She must have put on 25 pounds in just the last month! You know how she was supposed to be modeling Size 2 jeans today? She couldn't fit into them! We had to give her a size… well, let's just say it went way past two, and she barely fit into those, either! I've informed the agency about the problem, though, and they said that they're going to call her into a reevaluation session soon to check on the problem."

The two photographers glanced at Kirino and Ayase, who were busy talking to each other on a nearby bench.

"Well, break's about over. Time to start the photos again."

"Yeah, if the lens is wide enough to capture Kirino's ass."

The photographers beckoned to Kirino and Ayase, who ran back to continue the photoshoot.

"Okay, girls, both of you are going to be posing for this set. Really show off those clothes! Here we go!"

As the photographers began giving out orders to the girls as to how to pose, the contrast between Ayase's ideal model-type body and Kirino's enhanced figure really showed off how much she had grown over the last month. While only weighing in at 132 pounds, putting her body firmly into the "healthy and normal" category, nearly every part of her body was considerably bigger than Ayase's. Her face was the exception, as it remained as thin and as attractive as it had been when she weighed only 100 pounds. Her breasts, formerly nearly non-existent, had clearly begun the blossoming process, though they were still quite small, as little of her newfound growth had targeted that area. Once one's eyes lowered, however, her new size became apparent. While Ayase's stomach remained washboard-flat, Kirino had begun to grow a slight belly. While certainly not prodigious, the flesh of her abdomen had fattened and begun to emerge, and the immensely tight tank top she now wore clearly showed it off. As she shifted her body to the commands of the photographer, it jiggled ever so slightly when she made sudden movements. While she had no real love handles yet, her thickened waist betrayed the quite real possibility that they would emerge if she put on just a few more pounds.

However, it was quite clear what had changed the most about Kirino— her ass. While always shapely, even when she was incredibly skinny, the added mass it had acquired from Kirino's constant gorging had made it quite large, much more so that one would expect from a 135 pound girl. The dark blue fabric of the jeans she was modeling strained and groaned against the soft, abundant flesh of her rear end, a veritable dam holding back the swollen flesh of her growing booty. As she shifted and swayed her hips, posing proactively for the camera, her tiny jeans were forced to shift and conform to the changing position of her ample ass cheeks, powerless to resist the force of her weighty, imposing buttocks. As she posed sideways, bending over slightly, her butt stuck out by such a distance that even the photographer was stunned for a moment, taking a few seconds before capturing the image of the voluptuous girl.

"That reevaluation by the industry can't come soon enough," he thought.

******************************************************************************************

As Kirino left the modeling agency the next day after her reevaluation, she was in a very good mood. Considering the agency had just fired her due to her newly enlarged figure, this might be seen as a surprise. However, Kirino's excitement due to the results of her weight gain that she saw when the agency re-measured her and weighed her far surpassed any sadness she felt at losing her job. Her 5'5", formerly 100 pound, 32-21-32 figure had expanded into a new, 136 pound 34-26-41 body, pleasing Kirino to no end.

"I wonder if Kyousuke's noticed my new changes yet…"

The joy she gained from her enhanced figure and the potential for her brother to notice her thus overrode any disappointment she felt at being fired. Though the loss of income bothered her, she knew that she had enough saved up to last her for a while… and enough to buy plenty of food to grow even bigger. In fact, the person bothered the most by Kirino's firing wasn't even Kirino herself, as she found out a few hours later when Ayase showed up at her house.

"Hello, Kirino."

"Oh, hi there, Ayase! I'm surprised you're here, usually you call before you come over. What do you—"

"Kirino, are you home alone right now? Can we talk?"

"Er, yeah, by brother's out with his friend right now. What do you want to talk about?"

"Kirino… why didn't you tell me that you were fired? I just found out from another model that you were let go. Are you okay?"

Kirino mentally kicked herself for forgetting to call Ayase. "Oh, geez, sorry about that. It totally slipped my mind. I—"

"It slipped your mind that you were fired? I rushed over here thinking you'd be crying right now. Why don't you seem to care? And… well… I heard about why the agency didn't want you anymore."

Kirino smiled proudly. "Because I'm getting fat?"

Ayase was taken aback. "Ye— wel— uh… I just meant that I heard you've gained a few pounds lately, I wasn't going to be rude…"

"Ayase, the only thing I'd find rude about being called fat is that I'm nowhere near big enough to call fat yet. At most, I'm slightly chubby. But you may want to remember that description of me in a few weeks; it will describe me better then."

Ayase seemed to have trouble taking this all in. "What are you talking about, Kirino? Are you that depressed over gaining some weight that you've resigned yourself to becoming fat? It's not that bad! I've put on a few pounds before, everyone has… I mean, not quite as much as you, but, er, it won't be tough at all to get you back down in a few months. I can help, we'll put you on a diet and exercise together, and—"

Kirino raised her hand. "Ayase, I'm not 'resigned' to anything. Has it ever been like me to think I'm powerless? If I wanted to be a skinny model again, I could be back at the agency in a month. What I'm saying is that I don't WANT to be skinny anymore."

"I don't understand what you're saying, Kirino? How could you not want to be skinny anymore? No one can want to be… fat."

Kirino smirked. "Oh? And why not?

"Because— well, it's crazy. I mean, no one wants to have a disgusting body. You have to be skinny to be attractive."

"Oh really? Tell me something, Ayase: do I look uglier now than I did a month ago?"

"Of course not, Kirino! You've still got such a pretty face!"

"I'm not talking about my face, Ayase. What about my body?"

Ayase blushed. "Kirino, you… you're body is…"

"You can say that when I saw skinny, I made clothes look good. But do you really think my bony body was attractive? Feel this."

Before Ayase could do anything, Kirino lifted her shirt, exposing her pudgy stomach, and grabbed Ayase's hand, putting it on top of her belly.

"Kirino, what are you—"

"Come on, Ayase," Kirino said, rubbing Ayase's hand against her belly flesh "Isn't it nice that my body's soft now, instead of rock hard? And look what else is so much better." Kirino pulled her shirt down, turned around, and posed with most of her weight on one leg, showing off her wide hips and bubble butt. "Look how awesome my butt is with all the extra weight! No more tiny tushie for me, now I've got some serious junk in the trunk." She slapped her booty for emphasis. "Come on, give it a squeeze."

Ayase was beet-red from blushing now. "Kirino, please, I…"

"All right, all right, be lame," Kirino muttered, facing Ayase again. "But you see what I mean?"

"But… why are you gaining weight, Kirino? Just because you like how it looks on you?"

It was Kirino's turn to blush. "I— I have good reasons. That's… part of it, yeah. But anyway, I'm definitely planning on gaining more. I… I hope you understand that."

Ayase had a shocked look in her eyes. "Kirino, how can I understand what you're doing? I've never heard of anyone doing something so weird before. I accepted you when I found out you were an otaku, and that was weird enough. But… This is… I have to go." Ayase turned and ran away from the house.

"Ayase!" Kirino yelled. "Wait!"

******************************************************************************************

"Your sister has gained a significant amount of weight lately, hasn't she?"

Kuroneko's words surprised Kyousuke.

"That's a pretty blunt way of putting it."

Kyousuke, Kuroneko, and Saori were in an Akihabara café, awaiting the arrival of Kirino, preparing to spend the day browsing the many anime-related stores in the area. Whereas Kyousuke had expected Kuroneko to ask him or Saori about the recent anime that had been airing, he found that the immediate topic seemed to be Kirino's growing body.

"Regardless of your sensibilities, what I said is undeniably true. In the last seven weeks, she's grown quite fat. Each time I've seen her, she has seemed to be over 10 pounds heavier than the last time I've seen her. I suppose that's quite an accomplishment. I've never heard of any person growing so large so quickly."

"Now, now, Miss Kuroneko," said Saori, trying to defuse the awkward situation. "I doubt Mr. Kyousuke knows much about his sister's personal changes."

Kuroneko scoffed. "Even with his lack of knowledge, he lives with that over-enthusiastic idiot. Surely he has some inkling of why she seems to be eating herself into the size of a sumo wrestler. From what I've observed, she still seems to be as loud and obnoxious as ever, so I doubt it's depression-related. And surely she can't simply be unaware of what's happening to her. The fact that she's not clad only in her underwear means that she's surely bought a few larger clothes by now."

"Well… she seems to be eating a lot, I've seen that. But she's not sad about anything that she's mentioned to me… I do think she's having some trouble with Ayase again, but it can't be that bad, or else she would have told me about it. But it's not that bad, right? I mean, it's not like she gotten ugly or something."

"Hmm?" Kuroneko assumed an interested look on her face. The fact that she's nearly doubled in size doesn't make you think she's ugly? I see…" Kuroneko grew silent thinking to herself.

"Ah, here's Miss Kirino now." Saori said. All three of them turned their eyes to the figure entering the café— a very substantial figure, it turned out. Kirino's' rapid gain had continued unabated since her firing three weeks ago, and her thickened, yet still average body had swollen into a genuinely overweight one. While her face still displayed no noticeable changes, the rest of her certainly did. Her breasts, while still enjoying the smallest portion of her gain, had grown into B-cups. As she noticed the trio and waved to them, her incredibly tight tank top displayed their jiggling motion. Jiggling, however, was a motion that was not contained alone in her breasts. The fact that her top was a tight fit 15 pounds ago allowed a substantial wave of motion to be seen in her prodigious middle, the bottom inch of which was uncovered by her too-small shirt, displaying a good amount of the soft, tan flesh of her belly— which was rapidly approaching "gut" territory— that bulged past and over her short shorts. Her legs and the visible parts of her thighs also shook as she walked over to them.

"Hey everyone! Let's get going, we've got a lot of places to see today."

As the three seated anime fans got out of their seats, Kirino turned and began walking away. However, the three did not follow— something very big had received their full attention: Kirino's ass.

"How… how big is that thing?" Kuroneko whispered, almost frightened.

Kirino's ass had continued to greedily hog as much of the new, beautiful, and plump flesh on Kirino's body as it could, and was overwhelmingly her most dominant feature. At 53 inches, her vast hips swayed sensuously as she walked towards the exit, and both of her huge buttocks shoved against each other, fighting desperately for the limited space within Kirino's incredibly tight shorts, with each perfectly round and fat cheek being forced up by the movement of the other one, then falling down and pushing the other away again every time that Kirino moved her legs to take another step. Her shorts were so tight that a clear wobbling could be seen running throughout each bulging cheek each time Kirino's feet slammed into the ground. Her shorts were just large enough to cover her enormous derriere, but their small size left no means to mask how wide and fat her ass was.

Kirino stopped at the door, sending one last jiggle throughout her fat body. Noticing that no one was following her, she turned halfway towards the rest of the group, inadvertently showing off the extent of how far her massive rear end stuck out from the rest of her body.

"Hello, you guys coming?" She asked, with a questioning look on her face.

Saori recovered from her shock the quickest. "Er, yes, right away." Kuroneko attempted to mask the fact that she had been overwhelmed by the size of Kirino's bloated behind by quickly adopting her typical look of casual indifference, though the red flush in her cheeks remained. Kyousuke was the slowest of the three, not snapping out of his trance until Saori and Kuroneko were a few feet ahead of him.

"Why am I drooling?" He thought to himself, as he wiped the saliva from his lip and joined the others.

******************************************************************************************

The group wandered the streets of Akihabara for a few hours, stopping at stores to shop for anime, manga, and doujins, arcades to play new fighting games, and a few clothing stores. The more memorable moments from the day, not surprisingly, focused on Kirino and her exceptionally large posterior— early in the day, her wide hips knocked over an anime display case, a later trip to an arcade led to her spending over three minutes trying to wedge herself out of a seat with armrests, and in the last cosplay clothing store they visited, her attempt to force the skirt for a Meruru cosplay over her imposing buttocks led to them being torn, and her being forced to pay for them.

"GRRRRRRRRRRRR"

"What on earth was that?" Kuroneko said. "Is that the dark roar of Abbadon, singing the song of the world's end?"

"Heh, sorry, that was just me," Kirino said, smiling and patting her large belly. "I haven't eaten in a few hours, so I'm starving. Let's go to that maid café across the street!" Running at a surprising speed for a girl of her girth, Kirino reached the café and went inside, followed by the others.

At the table, Kirino ate like a wild animal. An appetizer ordered for the whole group ended up being nearly wholly devoured by her. She ordered three meals off the menu, ate them all by the time the rest of the group had finished their meals, and then ordered just as many desserts for herself. Other than the sound of Kirino gorging herself, the meal was actually quite quiet, as the non-fat members of the table mainly spent the meal in a shocked stupor, observing the incredibly appetite of Kirino.

"Whew!" Kirino said, eating the last bite of her parfait. "I sure am stuffed!" She patted her belly— which was now so large that her shirt couldn't even fully cover all of her navel— and turned to the rest of the group. "Why aren't you guys talking? Is the food stuck in your throat?"

"Er, no…" Kyousuke replied nervously. "I'll be right back, I have to use the bathroom."

"I too, have to use the bathroom. Excuse me" said Saori, her face a bit green.

As the two members of the party left the table, Kirino was left alone with Kuroneko.

"Are you proud of yourself, you glutton?" Kuroneko smirked. "I knew you got excited over the smallest of things, but seeing you have such enthusiasm for stuffing your fat body is quite amusing."

"Oh? What's that, you goth hipster? Are you jealous that I can eat all this delicious food while you're still eating just a few bites of rice, trying to stay as puny as you've always been?" Kirino replied, mockingly.

"Puny? I think the reason you use such an adjective to describe me is because you're used to seeing an annoying blob nearly twice my size every time you look in the mirror. Has your great weight exceeded 160 pounds yet?"

"I'm already 168 pounds, for your information, and every one of them makes me look even better. In fact, since you want to know so much, let me tell you my three sizes: 37-34-53." Kuroneko seemed unfazed by the news.

"I think you're just annoyed that you're so small and bony. You'd look a lot better if you'd just eat a little bit and put some weight on. Look at me!" Kirino smiled. "I'm much more attractive than a pile of skin and bones like you are now that I'm not obsessed with being skinny anymore."

Kuroneko smiled. "Ah… so you admit that you've grown so fat on purpose, then?"

"I haven't been hiding that! I just didn't want to say it around… my brother. That's all."

Kuroneko's smile grew into an evil grin. "Oh? And why is that? Is it because your brother notices you more at your current size?"

Kirino's face went beet-red. "What… what are you saying, you idiot! My stupid brother has nothing to do with this! I just like being fat, that's all! You… how could you even think that?" She turned her head away from Kuroneko, embarrassed to look at her.

Sipping her drink contentedly, Kuroneko continued to smile. "Well, well, it seems I've hit a nerve. Then again, even if you didn't intend it, it's not like your brother couldn't have paid you more attention, considering how much more of you there is now." Kirino remained silent. "But then again, it's not a bad plan, if he's into that type of woman."

"I told you, he has nothing to do with it!"

Kuroneko just grinned and went back to finishing her drink.

A few minutes later, Saori and Kyousuke returned to the table, looking slightly pale. After paying the bill, the lion's share of which was Kirino's, and saying their mutual goodbyes, the group parted outside of the café, going back to their homes. As Kirino and Kyousuke walked away, Kuroneko watched them. Observing Kirino's enormous ass sway and jiggle as she walked side by side with her brother, a grin came to her face.

"Now I know all that I wanted to."

Kirino shoved another cookie into her mouth, rubbing her fat belly contentedly — and what a vast amount of belly she had to rub! The now-191 pound beauty sported a genuine gut now, which bulged over her blue shorts. As her parents and brother were going to be gone for much of the day, she had decided to revel in her corpulence by wearing clothes she had bought when she weighed a mere 150 pounds, in order to really show off to herself all the progress she had made in her quest to be colossal. While her face, miraculously, still seemed to maintain the thinness of her 100-pound, model body, the rest of her was entirely different from the body she had had a mere two months ago. Her breasts, slow to make any sort of progress, had finally reached a respectable C-cup. For the first time in her life, she had a chest that actually had a substantial shake and jiggle to it whenever she shook or bounced her hefty body— and as she had never before had a chance to experience such a sensation, she kept her body in constant motion, so that she might continuously be reminded of her now-ample boobs.

It was not her breasts alone that commanded her attention: Kirino also was greatly enthralled by the other parts of her body that quaked and wobbled due whenever she moved. Her bulging belly and the vast amount of fat that covered it couldn't stay still for even a moment as Kirino constantly shifted her body. Unconstrained by her far too small shirt, which covered a pathetically tiny portion of her sizable gut, its tan, plump flesh bared itself in all its fat glory to the world, and Kirino couldn't help but smile every time she rubbed it and experienced how pleasurably big and soft it was.

Of course, even though it was always behind her, Kirino could never ignore her humongous rear end. Then again, it's quite difficult for anyone to ignore an ass that's over 58 inches in girth! So large that it overflowed and hung over her chair, Kirino's butt had plumped up into a true behemoth of a booty. Each titanic ass cheek, swollen with soft and malleable fat, continuously squished against her desk chair, which occasionally let out a loud creak, as if groaning against the burden of supporting such a heavy load. As her shorts were as ill-fitting as her shirt, a good portion of both the top and bottom sections of her ass were on display, as it was far too large to be hidden by such a puny pair of pants— her panties were quite visible, along with a good third of her ass cheeks. As it dominated her figure, Kirino had grown to favor her enormous derriere as the best part of her body— as much as she enjoyed watching her fattened breasts and belly quake and bounce, she loved watching the sensual shaking of her bulging bottom even more. She had earlier spent over 15 minutes observing her backside in a full-length mirror, and, taking advantage of its ample size, she spent most of this time shaking it, grabbing handfuls of it and jiggling it, and bouncing up and down to observe her cheeks clapping together.

Finished with her cookies and still hungry, Kirino sprung out of her seat, displaying all of the youthful energy that she had before she began her gain. Slapping her ass once more to feel its wonderfully soft flesh, she left her room and walked down the stairs, intending to get more food to satisfy her demanding belly. Upon reaching the fridge, she began her search for the most delicious and fattening thing she could find, hoping to put on at least one or two pounds today. Leaning down and into the fridge, causing every inch and pound of her enormous booty to bulge out behind her, placing it on full display, she began to hum a tune and slowly sway her wide hips from side to side in line with the rhythm. Any lucky soul who would have come across her at the moment would have had been treated to a view of a beautifully wide and full ass; a butt so big that its sheer size overwhelmed the puny shorts struggling to cover it; a rear end with two fat cheeks that were both infinitely jiggly and malleable, yet firm enough to be free of cellulite; a sensual and hypnotic site that, aided by its slow swaying back and forth, commanded one's full attention and overwhelmed the senses… and, by sheer chance, there was a person who had a full view of it.

"K— Kirino?"

Her heart skipped a beat. Someone was in the house with her! The skimpy clothes she wore so that she could enjoy her fat body's appearance could be seen by someone else! Kirino was a confident girl, and she had no qualms about getting fat to achieve her goal… but still, she wasn't ready for someone else to see her dressed so scandalously yet! Her face red with embarrassment, she turned around so quickly that another jiggle was sent throughout her body. She was met by a girl with a face as red as her own: that of Ayase.

"Ayase!? How did you get in the house?"

"I… you gave me a key, remember? I rang the doorbell, but you didn't answer, so I… came in to talk with you."

It had been over a month since the two had last spoken. After Ayase ran away from Kirino after discovering her newfound desire to gain weight, she had avoided Kirino at school.

"Oh." Kirino tried in vain to pull down her hopelessly inadequate shirt to cover her fat belly. Though her and Ayase had seen each other's full body while bathing in the past, Ayase had yet to set sight on all of her newfound flesh. "Er… maybe I should go change first—"

"No. I… I don't think I mind. It's about…that… anyway." Both Kirino's exposed abundance and the meeting of the two after a month's absence contributed to the tense and awkward atmosphere.

"About… me wanting to… get fat?"

"Oh, Kirino, don't say that!" Ayase's shock at the statement broke the atmosphere. "Why— why did you have to tell me about that? I never knew anyone could ever want to— that anyone could like being— oh, God, Kirino!" On the verge of tears, she covered her face.

Kirino was startled. She didn't quite understand.

"The problem is that you don't want me to be fat… isn't it?" Kirino said sheepishly.

"No!" Ayase cried. "I don't mind you being— you're still beautiful, even now. And… that's what's bothering me! Fat is supposed to be ugly! Why… why do I still find you so— I thought I understood… how I felt about you… we were friends… and now, I— Kirino, can't you go back to how you were before?"

"Are you— are you saying we can't be friends if I'm fat?"

"Oh no, Kirino! I won't make that mistake again! I don't want to leave y— I still want to be around you. But everything was so much easier to understand when we were skinny. We were skinny because we needed to be to be models and models are supposed to be the most attractive women. And… and you were my close friend, just that. Nothing unusual, nothing abnormal. I understood… I thought I understood everything then. But… but then this happened. I kept seeing you at school, getting bigger all the time. I couldn't stop looking… And now I think of you as… Kirino, can you just tell me why you're doing this? It can't be just a whim, can it? If you like being fat, than there must be another reason why you want to be, right? I need to know… is it for someone else? Does someone want you to be this way?"

Kirino grew even more embarrassed.

"Wha— what are you saying? I… well… I'm doing this for… for myself… myself and… and…" Her voice was down to a whisper. "Someone else."

Ayase breathed a sigh.

"So I'm not the only— so others… beside yourself… like fat bodies?"

"There… there are people like that, yeah," Kirino muttered, avoiding eye contact. "I mean, like you said… I like it."

"Then could you tell me what it is… that makes you like being fat?"

"Well, it's… complicated. There's just something about being so big… and you become so soft and your whole body becomes so much more touchable… and when you walk, you can feel yourself… that is, you're aware of how much space you take up, and… it's tough to explain if you aren't fat yourself."

Ayase was silent for a moment.

"I see." The awkward silence resumed. "Kirino… can I… touch you?"

"Wha¾ what!?" stuttered Kirino.

"Don't think that… it's not… I just want to see what you mean and get some sort of perspective… I think I might be able to if I can see what you are talking about."

Kirino gulped.

"I… I guess that's fine. Just… be gentle."

Ayase got close to Kirino… and walked behind her.

"I just want to see… what you mean."

Ayase pressed herself against Kirino's backside, causing her to shudder. She wrapped her hands as far around Kirino's soft belly as she could, and slowly rubbed her hands over the soft, fat flesh. Gently kneading her generous gut, Ayase whispered into Kirino's ear.

"Your waist… it's so big and soft."

Ayase raised her hands upwards… and began to feel Kirino's breasts.

"What… what are you doing?" Kirino gasped.

"Don't worry… I just… want to see…"

Ayase's hands were as skilled as a masseuse. She smoothly rubbed and clutched Kirino's breasts, giving them a very light shake."

"They're so small compared to the rest of you… but they're still bigger than mine. Now… be calm."

Kirino suppressed a moan as Ayase's hands left her breasts and found her rear.

"You really do have a big butt, Kirino. It's the biggest I've ever seen on someone our age."

Ayase was a bit rougher with Kirino's ass than she had been with the rest of her body. Perhaps she thought the copious layers of fat that made up her buttocks insulated them from feeling as much. Or perhaps she thought she'd have to be quicker in order to have time to explore the vast mass of fat that was Kirino's bottom. Regardless, Ayase was not aware that Kirino's ass was the most sensitive part of her body. Kirino grit her teeth, desperately trying not to gasp or moan as Ayase roughly grabbed handfuls of flesh from her ass, rubbed her cheeks, or slightly shook them.

"Ah… Ayase… no more… please…"

Ayase let her hands down, almost reluctantly. Both girls avoided looking at each other, their faces beet-red.

"Thank you, Kirino… I… I need some time alone for a while. I need to think about some things." She began walking to the door.

"Ayase… are… are we friends again?" Ayase turned around.

"I— I can't… I'll come back tomorrow. We can… talk about that then."

Kirino was silent as Ayase left. She was confused and embarrassed by what had just happened. Why couldn't Ayase be clear about whether she viewed Kirino as a friend or an embarrassment? Why had she seemed so repulsed by Kirino's fat body over the last month, yet today been wanting to examine it in such intimate detail? The thought that she might actually lose her best friend suddenly hit Kirino. Yes, she had known all the social problems that were sure to developed when she got fat, but she had discounted them as less valuable than the attention from Kyousuke that it might bring. Yet the idea that Ayase, her closest friend, might abandon her once and for all… she hadn't really considered the full implications of such an event. So confused and flustered over the events of the last few minutes, Kirino sat down on the couch and began to softly cry.

The door began to rattle as someone unlocked it. Kirino quickly shifted her tearstained face to the door. Was Ayase coming back? Had she already made a decision? She stood up, hopefully, only to find that the person opening the door was someone unexpected.

"I'm ho—"

Kyousuke's words fell flat as he saw his nearly 200-pound sister, dressed in clothes that displayed vast amounts of luscious, bulging flesh, with tears running down her cheeks.

Kirino, too, was stunned into silence. Her brother, the most important boy in the world to her, for whom she had nearly doubled in size, was finally setting his eyes on her body, as she had wanted him to. But she hadn't wanted this moment to be one in which her face was covered in tears, nor to be one in which she was taken by surprise at his appearance.

"Wha— What are you doing home!?" She screamed.

"What!? Akagi and I finished the project we were working on earlier that we planned!" Kyousuke was panicking as much as his sister, who was trying to hide her exposed body with her hands. "Why are you even wearing that right now!? I—"

"Pervert!" Kirino screamed. "Don't look!" She threw a couch cushion at his face.

Turning and sprinting away, giving him a prime view of her bountiful ass jiggling and wobbling with every step, she ran up the stairs to her room.

"Gah!" Kyousuke exclaimed to himself. "She really threw that pillow hard. My nose is bleeding."

******************************************************************************************

A few minutes later, his nosebleed under control, Kyousuke knocked on Kirino's door.

"Kirino? Are you okay in there?"

Receiving no answer, he tried the door. As it was unlocked, he went inside. Kirino, now changed into larger clothing that could actually cover (most) of her ample figure, sat on her bed, crying.

Sighing inwardly, Kyousuke decided to see what was wrong… after all, Kirino was still his little sister, right? Even if she was actually bigger than him now…

"Hey, you. What's wrong?"

Kirino sniffed, but remained resolutely silent.

"I saw Ayase leaving as I came to the house. Did you guys get in another fight?"

Kirino's face flared up angrily.

"You… this is all your fault!"

"My fault!? How is it my fault that she and you aren't getting along? Is it over anime again?"

"No! It's about…" Kirino hesitated to bring up the subject she had avoided talking about with her brother so far. "It's about… how I've… gotten so fat."

"…Oh." Kyousuke couldn't believe it, but somehow the situation had gotten even more awkward.  "Er… she doesn't want to hang out with you now?"

"I don't know! She wasn't being clear at all. She seemed to not like it one moment, then the next moment, she… she seemed to be okay with it."

"…I didn't even realize you were acknowledging that you've… put on some weight." Kirino looked up at him.

"Not acknowledging…? You thought I was embarrassed?" She stood up.

"Well, I… I just figured you were. I mean, usually when someone gains weight by accident, they—"

"Accident? You… you don't know why… why I gained weight?"

"Er, should I?"

Kirino was stunned. For all her efforts, her brother hadn't had the slightest interest in the expanding of her body, nor did he have any idea that she had done it for his attention. Her eyes watered.

"Oh, Kyousuke!" Tears once more poured from Kirino's eyes as she hugged her brother, her fleshy middle pressing against him. All at once, she left forth the emotions she had felt over the last two months, both those concerning Ayase and her potential loss of friendship and those concerning her brother. She squeezed him as hard as she could, crying on his shoulder.

"Kirino." Kyousuke returned the hug, his arms being partially engulfed by the fat that covered Kirino's body. "It's going to be alright. I'm not entirely sure what's going on here, but whatever it is, you'll make it through this."

Kirino continued to cry.

******************************************************************************************

The next day, Kirino was again alone in the house. In order not to risk the embarrassment of yesterday, she actually wore clothes that covered a suitable amount of her body. Though she missed being able to see all the rolls and folds that she had developed, along with the shaking of her soft body that she had so enjoyed viewing, she was mostly distracted from her body due to her anxiety. She knew Ayase would be over soon… and that it might be the last day of their friendship.

Kirino thought back on the experiences they had had together. For years, they had been the closest of friends, telling each other everything. They had worked together as models, studied together at school, and both of them knew everything about the other. Even when Kirino's otaku ways were revealed to Ayase, their friendship was still able to weather such a storm. Would Kirin's fattened frame really end all that?

"It would be so much easier if I understood what her problem is," thought Kirino. Indeed, Kirino was still very confused about the events of yesterday. She had initially assumed this was a repeat of the anime incident, with Ayase not wanting to be around an undesirable. But Ayase had specifically denied that. Rather, she had seemed to be conflicted over something else entirely… something that made her curious about Kirino's newfound girth, curious enough that she had explored Kirin's body.

Kirino touched her breasts, remembering the cool touch of Ayase's hands on them. Could Ayase really be repulsed by fat if she was willing to touch it so… intimately? She had seemed eager to touch and experience all of Kirino's expanded assets, from her breasts to her belly to her big butt. Kirino still felt confused about the experience.

"Ding-dong!"

Unlike yesterday, when Kirino was too concerned with stuffing herself to hear Ayase's arrival, she had managed (as well as she could) to focus less on her hunger. Hearing the ring of the doorbell, she stood from her chair, took a deep breath, swelling her stomach out even further than usual, and nervously walked to open the door.

With each step towards the door, and each corresponding jiggle of her body, she grew more and more nervous. Would this really be it? Would her friendship with Ayase end today? As she took her last steps towards the door, her will almost failed her, and it took all of her mental fortitude to slowly raise her hand and turn the door.

Ayase stood upon the porch. This is it, Kirino thought. Is she going to do it quickly? Will she be as sad as I will? Will she…

"Kirino!" Ayase yelled, with a determined look on her face. "I… I want to get fat!"

…
…
…

"What?"

Of all the possible things Ayase might have said, this was one that had not even crossed Kirino's mind.

"I… I want to get fat with you, Kirino!" Ayase's  eyes blazed with a fire that one normally expected to see on the faces of determined warriors. "I don't want our friendship to end, and… I want to understand why you like being fat so much!" Kirino took a second to respond, still trying to process what she had just heard.

"But… why? You're… you're one of the most popular girls in school, you're a model, and you're… well, you're perfect. Why would you want to be like me?"

"Kirino, so were you! And you got fat, and you don't seem to regret it. So… so I want to do it too. I still want to be your best friend, and I want us to share the same experience. So if you'll forgive me… for ignoring you for so long… I hope we can still be friends."

Kirino finally managed to gather herself. Ayase still wanted to be friends! And she wants to gain weight just like I did! Kirino's face lit up with a smile.

"Oh, Ayase! Of course I forgive you! I was so worried that you didn't want to be friends with me any more… I'm just glad that we can still be close. And… are you sure that you want to be fat like me? I mean, you've seen what I look like now… and yesterday, you… well, you've definitely seen what the body of a fat girl looks like. Do you really want to be like that?"

"I'm sure, Kirino. I thought about it really hard last night. I want to be as big as you… or even bigger! I'm tired of being skinny. I want to have full breasts, a soft stomach, and a big butt, just like you!"

Kirino almost took that as a challenge. This pipsqueak wanted to be bigger than her?

"Heh. Bigger than me, huh? You're going to have to work pretty hard to do that. I've got quite a head start on you, and I don't intend to let up now. I like being fat way too much to stop at a measly 190 pounds! But if you really want a body like this," Kirino posed, her tight clothes showing off every bulge of her body, "it's going to take a lot of work. You're gonna need my help to do it. So come on in, and I'll teach you the basics of gaining…"

******************************************************************************************

Ayase took a deep breath as she stepped on the scale.

Wearing only her bra and panties, she was easily able to see the effect that the last three months had had on her body. Kirino was certainly an excellent teacher when it came to gaining weight, she thought. Ayase's desire to see what it was like to be fat had thrilled Kirino, and her constant shoving of food towards Ayase had worked wonders for her figure.

Viewed from behind, the first thing one would notice about Ayase was her expanded rear. Though it was not the massive ass that Kirino had, it was still quite substantial. Her cheeks bulged out behind her, their soft, jiggly flesh making them look inviting, almost as if they were begging for a strong hand to grab a soft handful of her booty fat and gently squeeze it. Her undersized panties were consumed by her rear's abundance, turning them into a veritable thong. Her back, however, was also quite a pleasurable sight to behold. No longer the bony, statuesque back of a model, it was now covered in roll after roll of soft, quivering flesh. Substantial love handles were clearly visible around her waist, and if one were to quickly rub one's hands up and down her sides, her whole back would be set aflame with motion as her malleable folds would shake and rearrange themselves.

However, Ayase's gain was far more apparent when she was viewed from the front. As she was not the bottom-heavy beauty that Kirino was, her extra weight had settled elsewhere- primarily on her belly and breasts. Ayase's boobs had begun filling out almost immediately after she started gaining, and had never really stopped. Her massive mammaries overwhelmed her E-cup bra, a large portion of them spilling out. Each boob was like a soft and round monument to fertility, and their substantial size made her chest the envy of all other girls in Japan. Much like her face, which was still nearly as skinny as when she started her gain, her breasts retained an aspect of skinniness in that they were (for the most part) relatively droop-less, as, fighting gravity with all their might, they only slightly hung down from her chest.

However, as much as her breasts commanded the attention of those who viewed Ayase from the front, it was not her boobs that were her dominant feature. Unlike Kirino, who had really packed it on in her rear, the biggest part of her gain had gone to her colossal belly. Entirely hanging over and covering her panties, her massive gut was so big and fat that Ayase had entirely given up on wearing shirts that covered its vastness, instead opting to wear shirts that emphasized its size, often so small that they showed off her cavernous navel. Each step she took sent it swaying and sloshing, its sheer girth shocking and awing anyone who saw it, whether in curious disgust, or, in the case of those who appreciated the fuller female figure, with pure, animalistic lust.

The scale finally finished calculating just how much the beautiful, bulging girl now weighed.

"Two— two hundred and one! I finally made it over 200 pounds!"

Took you long enough!" Kirino said, snacking on a bag of chips as she lazily rested on her bed.

The last three months, of course, had not merely produced rapid growth on Ayase's body. As Kirino had promised, she had not been satisfied with weighing only 190 pounds, and had continued to gain with Ayase. And it certainly showed. Though she was not wearing mere undergarments, as Ayase was, her small pink top and her short blue shorts hadn't had a size upgrade in some time, and her body thus spilled and bulged out of her tight clothing in every way it could. Neither she nor Ayase minded, however. In fact, whenever they were together, both of them had grown quite comfortable wearing clothes that showed off their expanding bodies. Often wearing clothes that toed the line for what was considered indecent exposure in public, it had become a tradition for the two to wear clothes that showed off exactly how much of them had grown, part of an informal competition forming between the two of them as to who could become the biggest. And Kirino's clothing, or lack of it, definitely emphasize that she was winning.

It was almost a proof of divine existence that the now 244 pound girl could still maintain a skinny face, yet miraculously she had done so. However, a simple glance at the behemothic beauty showed that that was the only part of her that hadn't grown. Her breasts, while not the Taj Mahals than Ayase was equipped with, were still quite big and full, though their growth had been minimal since they had reached C-cup size, though they were still large enough to bulge seductively against her tight shirt. This same shirt, in fact, barely covered anything more than her breasts, as the titanic belly she was currently rubbing was so vast that it would have taken a shirt more than twice as large before there would have been enough fabric to cover it. As she was lying on her side at the moment, her wonderfully fat and round gut bulged out and spilled over her shorts and rested on the bed. Though more of Ayase's weight had gone to her middle than Kirino's, Kirino was still the bigger girl, and thus both of their stupendously bloated and jiggly bellies were of about equal girth. Because of this, the question as to who had the fatter midsection was thus their most equal battleground in their desire to be bigger than each other, and as such, Kirino loved to show off her belly and its swollen size as much as Ayase did.

However, Kirino still undoubtedly had Ayase beat in the rear department. Kirino's ass had achieved a girth of over 64 inches, so large that it absolutely defined her figure. At such a monstrous size, Kirino's butt was downright intimidating, its bulk made all the more obvious by the fact that her colossal butt cheeks, huge, fat, and incredibly soft and squeezable, still maintained enough of a youthful firmness that they bulged out an immense distance, constantly threatening to rip her incredibly tight shorts, which could barely contain her booty's plush abundance, to shreds. As there was so much of her rear end nowadays, there was that much more that jiggled, bounced, and swayed seductively as she moved her fattened body while walking. In public, one couldn't help but latch one's eyes on to her mountainous posterior and its hypnotic, lust-inducing, pendulous movements. Every shift her cheeks made as she walked, every jiggle that ran through all her malleable booty fat, every swing of her dangerously large hips all demanded the full attention of male viewers. Kirino was fully aware of all the attention her mountain of a derriere was receiving, and she loved it. Often giving it a surreptitious squeeze, grabbing as much fat as she could, or bouncing on her feet to cause it to shake wildly, her enormous ass had caused an innumerable amount of spontaneous nosebleeds amongst young teenage boys, and some girls as well.

Heaving her bulk off the bed, which let out a loud squeak, almost as if it were relieved to no longer have to support Kirino's great weight, she walked behind Ayase, who was still blissfully staring at the scale's results.

"Hm… are you sure you're really over 200? Your belly seems a bit small," Kirino said, wrapping her arms around as much of Ayase's corpulent middle as she could.

"Ah! Kirino, what are you doing?"

"Ooh, it is a bit bigger than it was!" Kirino grabbed the sides of Ayase's belly and shook it, sending it into a spasm of motion. It's not as big as mine, but then again, not much of you is as big as me, huh, skinny?" Kirino let go of Ayase's fat belly.

"Skinny?" Ayase turned, her face slightly red. "I'm hardly skinny anymore. I've grown pretty fat recently, and you shouldn't—" Kirino's sudden laughter cut off Ayase. "What's so funny?" Kirino calmed herself.

"Oh, listen to yourself, Ayase. You're bragging about how fat you've gotten recently. Can you imagine yourself saying that just a few months ago? It's just so funny how much you've changed since then."

"I… you're right, Kirino. When I was skinny, I couldn't have ever understood why anyone could enjoy being so… big. But you were right when you told me how I'd have to experience it to see why… and now I… I…" Ayse's eyes started to water. "Oh, Kirino!" Ayase hugged Kirino, causing their considerable bodies to press against each other, rolls of fat colliding.

"Woah, what's with the waterworks?"

"I'm so happy that we're both like this. I've never felt so close to you before. Before, we were just friends, but now… we've both chosen to do something different, to be fat, just because we want to be… even though society doesn't like it, we can… we can…"

"What are you talking about, Ayase?" Kirino smiled. "We both got fat because we liked it! How would you like to go back to the time when you had a flat chest, instead of those ballistics you've got now?" Kirino briefly bounced Ayase's breasts in her hands. "Or how would you like it if we went back to having rock-hard waists instead of these huge, soft, bellies?" Kirino grabbed a handful of belly fat and shook it. Turning around, she smiled at Ayase. "And can you imagine me going back to having a tiny butt and losing this big, beautiful booty of mine?" She slapped her rear, sending a ripple throughout her fattened posterior. "Even if we had… other reasons… at first, the point is, we're staying big and beautiful because we love being fat!"

The doorbell rang.

"Oh, that must be Kanako! I'll get the door, you put on some clothes, Ayase." Kirino bounded out of the room, her body wobbling wildly.

When Kanako entered the room, the contrast between her small size and the titanic bulk of Kirino and Ayase was quite laughable. Together, the two girls outweighed their diminutive friend nearly five times over. Standing between the bulging breasts, bloated bellies, and ample asses of two scantily clad BBWs, Kanako took on her typical look of bored disgust.

"Ugh. You guys really let yourselves go. If we hadn't been friends for so long, there's no way I'd still be around you disgusting fatties." Kirino eyed Ayase mischievously.

"Disgusting? That's what you think of us? I don't know if you've noticed, Kanako, but both of us 'fatties' are easily twice as big as you. Are you sure it's a good idea to insult someone when you're so small and we're so big?" The two girls slowly began to close in on Kanako.

"I— what are you doing?" Kanako had a look of fear in her eyes.

"You know, Kanako, calling me disgusting really makes me angry," Ayase said, smiling. "In fact, I think I'm so angry that I'm going to have to punish you."

The two behemoths slowly pushed their large, flabby stomachs into Kanako from opposite sides. Her small size, and their largeness, caused their fat bellies to engulf Kanako and touch each other, trapping her in a soft, fleshy, prison.

"Hey, knock it off, you guys." Kanako squirmed, trying to free herself. All her efforts, however, simply caused Kirino and Ayase's bellies to jiggle rapidly.

"Hee hee! That tickles, Kanako!" Kirino said. "Come on, enjoy this. It's not often that you get to experience something as soft as two fat girls rubbing against you. Don't you enjoy how big and soft we are now? It feels good, doesn't it?" Kanako began to blush, her flesh being stimulated by the quaking motions of the girls' fat flesh.

"G— Guys, stop, I… I…" She began to gasp.

The two girls laughed. They backed off, letting an exasperated Kanako catch her breath.

"Be happy, Kanako," Ayase said. "Kirino could have decided to sit on you instead!"

"Yep!" Kirino turned, showing off her massive rear to Kanako. "You'd have never gotten out from under there." She slapped her ass for emphasis.

Kanako quickly lowered her gaze, her face getting ever more flushed.

******************************************************************************************

"Hey, slowpokes, hurry up!"

Kirino bounded ahead, her hefty body making enormous amounts of noise as each step she took slammed into the ground. Kyousuke, Kuroneko, and Saori followed.

"Your sister's growth continues unabated, doesn't it?" Kuroneko asked.

"I guess so," Kyousuke replied, smiling. Ahead of them, Kirino waved.

"Kyousuke, let's take a picture in this photo booth!"

"Wha— why would we do that?" Kyousuke said, shocked.

"Don't get the wrong idea, idiot! That's what— that's what photo booths are for right? I just want a picture, and it would be weird if I took one by myself!" Kyousuke shook his head.

"Fine, fine, let's take one."

However, Kyousuke was immediately struck with a problem as he followed Kirino into the booth: how on earth were they both going to fit?

Kirino's magnificently overweight body took already took up nearly all of the seat, her colossal thighs and rear spreading out over the seat. As Kyousuke tried to squeeze into what little space remained, his legs pushed against hers, being partially engulfed by her leg fat. He also was faced with the dilemma with what to do with his arm that was nearest to Kirino's: her enormous belly took up as much space as her titanic booty, and in order to get into the picture at all, he'd have to press it against her gut.

"Moron, what are you doing? Stop squirming, we need to take the picture!"

"I'm not squirming, I just can't fit next to you!" Kirino blushed.

"Wha— what are you saying?"

"I'm saying you've gotten a bit too fat for small places!"

Kirino's heart fluttered. Until now, Kyousuke had only reluctantly mentioned her ballooning in size. But now he was fully and rankly acknowledging her voluptuous body… and even feeling it as he fought to shift enough of her squishy bulk to be in the picture.

"Kyousuke… you noticed that… that I…"

"Hey, it's taking the picture!" Kirino snapped out of her daze.

The resulting picture was one of an enormous teenage beauty with a shocked look on her flushed face whose body was currently spilling out of her clothes and partially engulfing the smaller body of her skinny brother, who was barely in the picture at all.

Kyousuke sighed, seeing the picture.

"Well, we can always take another one."

"What are you talking about? This picture's fine." Kirino snatched it from his hand and continued running along to the next store. Kuroneko shook her head.

"That girl… her exuberant idiocy is matched only by the corpulence of her body."

Kyousuke looked at her, about to respond. His attention, however, was taken by his sudden observations about the black-haired girl's clothing. It seemed as though her gothic dress had recently been… extended in size. And now that he thought about it, isn't that the beginning of a belly pushing against the front of the fabric?

"Huh… looks like my sister isn't the only one putting on a little weight lately."

Kuroneko looked down, hiding her smile.

"I don't know what you're talking about, senpai."
