Ruri Gokou, the beautiful, dark-haired otaku, was doing what she did most nights- drawing in her notebook. Filled with her artistic interpretations of the day-to-day events she had experienced and expressions of her hopes for the future, the book allowed her to express herself through her alias, Kuroneko, the Queen of Nightmare. Yet the drawing she was working on tonight was a different one than any she had ever done.

Putting her pencil down, she took a look at her sketch. While the image was typical in that it was of her usual cosplay, the girl wearing it looked very different than Ruri. Rather than the lithe and tiny form of the artist, the girl's body was large and imposing. Her chest was perhaps her most eye-catching feature, as her breasts boisterously protruded from her torso. Below, the girl's enormously thickened middle threatened to overwhelm the fabric of her dress. Her overfed belly bulged out and over her skirt, as if demanding to be fed more so that it might grow even bigger. A secondary sketch showed the girl from behind, and this view of her was just as shocking. Wrapped in thigh-high socks, a hint of her fattened calves were seen resting on top of her large legs. Yet though a black skirt covered her lower half, it failed to hide her most obvious asset- her rear end. A booty of monumental proportions, the outline of each cheek was clear as they pressed against her tight clothing. If one could have seen her figure in motion, rather than on paper, it would have been obvious that such a nice, wide, bottom would have had a sensual sway as the girl walked.

Yes, the drawing was of a fat girl. Yet why was such an unusual image in Ruri's notebook? A closer look at the soft, slightly rounder face of the overweight beauty gave a hint. Slightly below the girl's left eye, a tiny beauty mark betrayed the identity of the figure. Along with the shiny, jet-black hair  in a hime cut, there was no doubt that Ruri had drawn a picture of herself, but with well over a hundred pounds of soft, fat flesh coating her body.

She smiled. “There is a certain beauty in this form, isn't there?” she said to herself. While she had never before considered heftier females especially alluring, recent events had come to bear on the young girl's mind. Watching her fellow otaku and friend, Kirino Kosaka, fatten up to over twice her original size over a period of just a few months had been shocking to her. After knowing the girl as a skinny, beautiful athlete- indeed, she had the body befitting her career as a model- watching her grow into a behemoth of a woman had rocked Ruri's world. This was intensified by the fact that the gorgeous brocon retained just as much of her attractiveness after her growth as before. Rather than becoming a hideous blob, Kirino's naturally curvy form had simply increased in girth, her curves growing considerably curvier. And Ruri found her newly fattened features to be fascinating. Who had thought that a big belly and a huge behind like Kirino had could increase one's allure, rather than make one hideous? Watching her confidently strut down Akihabara, her body shaking and jiggling, had opened Ruri's eyes to a whole new world of beauty that she had never before known.

But an even more amazing recognition came when Ruri realized why Kirino had gotten so large. Rather than becoming a glutton out of sheer laziness, Kirino had willingly embraced life as a fatty. After the talk they had had at the cafe earlier today, the reason became clear: Kirino was attempting to entice Kyousuke.

“So Kyousuke likes larger women, does he?” Ruri had thought. She couldn't deny that this was a blow to her ambitions of becoming a couple with him. Ever since meeting him for the first time, she had been struck both by his handsomeness and his inner strength. While not especially smart, the boy's desire to better relations with his sister and his friendliness to the normally-ostracized Kuroneko had quickly won her over. Yet while Ruri was certainly not bad-looking, especially to those who prefer a tinier female figure, she doubted she would appeal to a male who enjoyed copious amounts of femininity. And so, after pondering it over late into the night, Ruri had come to a decision: If Kyousuke likes fat girls, then she'd fulfill his desires. Kuroneko would grow huge.

Yet this was easier said that done. While her sketch might reflect her wish to be big, she couldn't simply draw new weight on herself. In fact, Ruri had long known that even large amounts of food failed to make an impact on her body. Her rapid metabolism, combined with the small amount of food she could stomach before becoming full, kept her permanently skinny. While this would be a blessing to most girls, it now served as a curse. Wistfully looking at her idealization of herself as a fat girl, she sighed. She was going to have to figure out how to get past this first hurdle if she ever wanted to compete with Kirino for Kyousuke's affections. Pausing only to label her new drawing “Debuneko,” the young girl turned off the light and fell asleep.

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

Kyousuke heard a muffled boom coming from down the hall. At the same time, a slight shudder ran through his room, causing the various possessions on his desk to move a bit closer to the edge. While a normal person might panic at such an event, thinking it was an earthquake, the boy had grown used to these events over the last few months. Such noise had become a common occurrence ever since his sister had ballooned up into a 250 pound hottie.

“Four... Five... Six!” The fiery young girl, alone in her room, counted each jumping jack she did. Each leap Kirino performed up to the ceiling sent her huge body into spasms of motion. Clad only in a sports bra and tight-fitting shorts, any young male attracted to big women, and plenty that weren't, would have been in heaven if they could have watched her. As her full poundage collided with the floor, waves of motion traveled through her fleshy form. Her breasts, while somewhat small compared to the rest of her, were still big enough to have a significant bounce. But her lower features all moved much more. Her belly, a huge gut that stuck out proudly in front of her, a true monument to her goal of being big, wobbled intensely. Even though it was partly packed with food-- it usually was, as there was rarely a moment in her waking day where Kirino wasn't stuffing herself-- and thus a bit less malleable, its movement was still very impressive. Yet her ass, her biggest feature, and the one she was most proud of, wiggled and jiggled more than any other part of her. Her shorts, a size or two smaller than they should have been, left little to the imagination. Over 60 inches in circumference, her booty was so big that it almost seemed to have its own gravitational pull.

It might seem strange that such a rotund girl was so diligently performing exercise. But even at her level of enormity, the lively girl retained the boundless enthusiasm of an athlete that she had always possessed. And while she may have willingly embraced life as a fat girl, Kirino had no intention of letting herself become a lazy slob. After all, her desire to be large had begun after seeing the compromising magazines her brother kept under his bed. Filled with young, attractive, and very fat women, Kirino realized that keeping herself in the best shape she could under the circumstances was crucial if she wanted to retain her beauty. And while the exercise may have caused her to burn off hundreds of precious calories and thus risk losing the enormous body she had worked so hard to get, in her mind, such a danger was just an excuse and motivation to consume even larger amounts of food.

After fifteen minutes, sweating profusely, Kirino came to a stop. Even with her energy and determination, with hundreds of pounds of fat weighting her down, she could only exercise in short stints. Panting heavily, she took a look in her full-length mirror.

“Whew... Still looking good!” Kirino shook her body, watching it shake all over. Perhaps because her gain had been intentional, she had never found her fat form ugly. Rather, it excited her. As she left her room and walked to the bathroom to talk a shower, she reflected on the events of the previous months. Ever since she had decided to get fat, her world had completely changed. With her newfound girth, she had to give up her modeling job, her athletic competitions, and her popularity at school. True, she was still getting some of the top grades in her class, and she was, thankfully, able to devote even more time to her otaku hobbies now. And it wasn't though she was ostracized at school, especially since her close friend and fellow star of the class, Ayase Aragaki, had become a big girl as well. The two of them retained a great deal of the beauty they had when they were skinny, even though their bodies had swelled up to more than twice their original sizes. They still got plenty of lustful looks from the male student body, even if most girls now scorned them.

Stripping off her clothes, Kirino got into the shower. As she felt the hot water flow over every curve of her body, she remembered how even her perspective on beauty had undergone a transformation. While she had worried at first that she would find herself hideous as she grew larger, after the first twenty pounds or so, Kirino had come to realize how much she loved her new form. She grew excited as she ran her hands over her naked body, feeling its countless inches and pounds. She grabbed a part of her belly and squeezed it, enjoying the sensation she experienced as its soft form moved between her fingers. Her big belly had become a great comfort to her over the previous unstable months. Whenever she felt lonely or sad, she'd rub it as it bulged over her shorts, feel its soft underside as it hung slightly downwards, and pat it and watch it jiggle. But while her belly may have made her happy, her boobs and butt made her feel something else. Kirino had never realized just how much she could be turned on by her own body until she had grown huge. But as her breasts and her rump grew swollen and bloated with fat, she began to feel much more womanly and sexy that she had when she was skinny. Now at her heaviest, she often would lose control of her sense whenever she was naked, and now, surrounded by steam and water, she began to feel those increasingly-familiar urges. As she felt her body, constrained as it was, rub and squish against the shower wall, she was again made aware of how large she was. She started squeezing her breasts, allowing them to come together, then rapidly releasing them. Moving on to her belly, she began to knead its flesh faster and harder than she normally did. Moaning now, rapidly losing control, she began to bounce up and down, feeling her whole body shake. She grabbed as much of her ass as she could, feeling how enormous it was. Naked and heated, Kirino felt as though she was going to explode. Yes, she was about to... about to...

“Ding-dong!” The doorbell wrang.

Kirino almost slipped as she woke up from her daze. She had completely forgotten that Kuroneko and Saori were coming over today. Rapidly drying herself off-- no easy task when your body is so huge-- she put on a clean pair of clothes and headed to meet her fellow otakus.

At the front door, Ruri and Saori, the shockingly tall, glasses-wearing leader of the otaku circle Kirino and Kuroneko were part of, came into the house and took off their shoes. They had grown used to coming to this house, both to see Kirino and her brother. As they walked into into the living room, Kyousuke came down the stairs.

“Oh, hey, guys!” Kyousuke said. “Kirino told me you'd be coming over to watch Vienna Girls. What's going on?”

“Nothing worthwhile ever occurs in the day-to-day existence in this horrible world,” Kuroneko proudly uttered. “I don't see why you'd even ask such a foolish question.”

“Now, now, Miss Kuroneko,” Saori gently commented. “I wouldn't say nothing interesting has happened to you recently. Didn't you come in first in the online shooter competitions just yesterday?”

“Woah, really?” Kyousuke seemed excited. “That's amazing, Kuroneko! Doesn't that mean you'll be going on to the country level?” The talented gothic Lolita blushed.

“Y-Yes, it was merely on the local level. It was not anything of consequence... the competition was as pathetic as the quality of the game. I could have made a much better one.” Kyousuke opened his mouth to respond, but was interrupted by the heavy footsteps at the top of the stairs.

“Miss Kirino!” Saori waved to her. “Vienna Girls starts in ten minutes! Are you ready?” Kirino could hardly contain her excitement.

“Of course!” She bounded down the stairs with the speed of a girl a hundred pounds lighter, causing the poor structure to creak and groan. “I can't wait to see whether Naples-chan will get together with Ferdinand or Jospeh! And I wonder if little Neuchatel will end up with Swistzerland or if she'll go back to her big sister Prussia!”

“Well, I'll leave you guys alone to watch your show. Have fun.” Kyousuke maneuvered past Kirino's girth and started up the stairs.

“Hold it!” Kirino grabbed his arm, anchoring him to over 200 pounds of otaku. “I saw you watching it last week, you should watch this episode, too!”

“Huh?” Her brother struggled to continue up to the next floor, but his efforts couldn't move his massive sister an inch. “But I have homework due tomorrow! I don't have time to watch anime!”

“You should have thought of that before Kuroneko and Saori came over! Are you going to be rude and just leave them alone?”

“If Kyousuke does not wish to watch it, you shouldn't force him to.” Kuroneko interjected. “It is, after all, a very mediocre show, as all anime this season is. Perhaps you and Saori could view it while your brother and me both go up to his room instead?” She smiled sinisterly.

“W-What are you talking about, you idiot! That's it, Kyousuke, get over here!” Kirino made a determined stride to the living room, dragging her protesting brother along with her.

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

A few minutes later, the four of them were sitting in the living room as the show began. Saori sat on a nearby chair while the other three sat on the main couch in front of the television. Though their couch was meant to seat three normal-sized people, both Kyousuke and Kuroneko, sitting on the sides, were slightly constrained by the large girl in the middle. Kirino's outfit, as small and snug as nearly all of her clothes were, barely constrained her excess. As such, her belly poured out over her tight blue shorts, exposing itself to the views of all three others. Her gigantic rear spread out as she sat, and alongside her very generous love handles, served as a fleshy wall that pressed against her brother and her friend.

“Er, Kirino?” Kyousuke slightly poked the side of her belly, his finger sinking into its softness. “Could you possibly move a little bit? I can't-”

“Quiet, it's starting!”

The show began with a bang, as the trigger-happy Prussia fired her cannons. Vienna Girls was a relatively obscure show that combined historical accuracy with romance. Set in 1814, the major characters served as personifications of the nations of Europe at the end of the Napoleonic Wars. As the title implied, most of the countries were women, and especially feminine ones as well- nearly all of them had large chests and curvy hips. In between their negotiations over the fate of Europe, the nations fell into love triangles, duels, and all manner of distractions from serious business. The main plot of this episode seemed to be a fight between the black-haired Prussia and the red-headed Britannia. Prussia, with the help of her ally, Russia, was attempting to steal the crown of the tiny and shy Saxony-chan, who was being defended by Britannia and her friends, Austria and France.

“Boring!” Kirino yelled, taking a quick break from stuffing herself with the huge tub of popcorn resting on top of her gut. “When are they going to get back to the romance plot they were having last week?”

“If you weren't such a fool, you would realize why this is much more important than who is courting Naples.” Kuroneko scornfully replied. “If Prussia manages to steal the Saxon crown, the secret treaty that Britannia, Austria, and France signed will go into effect. They will kick Prussia and Russia out of Vienna and go to war with them. That would cause the whole balance of power to again be disrupted, giving the sorceress Elba the perfect distraction to reverse the binding spell on Napoleo-”

“Oh, commercial break!” Saori stood up. I'll be back in a moment, I need to go refresh in the restroom.”

“I should head out for a second too... I might as well grab some homework and do what I can...” Both Kyousuke and Saori left the room, leaving Kirino and Kuroneko alone.

Kirino put the popcorn bowl down, nearly empty, and stood up. She waddled into the kitchen in search of more food. Ruri followed behind her to the fridge.

“I see that you've managed to grow even larger since the last time I saw you.” Ruri grinned. “Though I'm not sure whether it is your middle or your rear that has grown the most.”

“Yep! I'm a growing girl!” Kirino gave her gut a slap, causing it to wobble. “And you're just as puny as ever! I bet you don't even weight a hundred pounds!”

“It's hardly fitting for you to mock me. Few in our society would consider your body to be better than mine.” Ruri tried to hide her newfound goal. “In fact, how did you go about ruining your old figure anyway? I would assume that, as an athlete, you had a metabolism that prevented you from easily gaining weight, and yet you grew so quickly.”

“Oh, that?” Kirino reached into the freezer, her tiny shorts exposing the full contours of her full bottom. “Yeah, it was hard at first. Just eating until I was full didn't do anything. It was only after I one night when I ate way more than I normally did that I started to gain weight. I felt miserable that first night, but I think I stretched my stomach to the point where I could eat more than my body could burn off. Now I can eat pretty much all day and never get full!” She pulled a gallon of ice cream out, grabbed a spoon, and began digging in. It was obvious that she wasn't about to share her dessert with anyone.

“Interesting... so consuming a large amount of food initially can build up a greater capacity for later meals.”

“Yep! Why, you thinking of putting on some weight yourself? I bet you'd look better with some meat on your bones, and you'd at least get a fuller chest than the washboard you have.”

“Y-you...” Kuroneko blushed. “I... admit I have thought about it a little.”

“Well, great! You can borrow some of my smaller clothes if you start outgrowing yours. But don't pack on too much! I like being the biggest girl around here, and I doubt you could pull it off as well as Ayase and me.” The bulging beauty gave Ruri a bump with her generous hips, causing the tiny girl to stagger back. “Not like you could ever get to this size anyway!” Ruri watched Kirino's massive booty sway from side to side as she walked back into the living room.

“Of course... I wasn't thinking of that at all.” She grinned.


“And did you brush your teeth?”

“Yep!”

Ruri was tucking her two younger sisters into bed. Since all three of them had come home from school, the eldest sibling had been responsible for caring for them. With both of her parents busy at work and not set to return until early in the morning, Ruri had cooked dinner, played with them, and helped them prepare to sleep. Though it was only 9 o'clock, she insisted, like a good sister, that they both get their rest. Of course, she had other reasons for getting them to bed so quick.

“Now, both of you, have a good night's sleep.” Ruri flicked the light switch and shut their door. She walked to her room and opened the door, exposing her plans for the night. A great deal of cheap food rested on top of her bed, ready to be eaten and consumed. Ramen, chips, cheap store-bought dishes of rice and meat made up the bulk of the food, though there were also a few cans of soda. Ruri's goal of devouring enough food in one setting to increase her stomach capacity, a lesson she had learned from Kirino, looked quite likely to be achieved tonight, if she could manage to eat and drink it all.

“No point in eating without something to do.” The otaku opened up her laptop and opened an episode of Vienna Girls she had recently downloaded. She moved most of the food over to her desk, clicked the Play button, and started eating some of the chips. “These really are good,” she thought to herself. “It's a shame I've always avoided them until now.” She smiled as she realized her path to largeness freed her from worrying so much about what she ate all the time. It didn't matter what she ate now so long as there was a lot of it.

The fact that the episode was relatively boring to her caused her to focus more on her eating. The plot was mainly a dispute between the personifications of Spain and Portugal over the tiny gemstone of Olivenca. Ruri couldn't see much point in the argument- it wasn't an especially pretty stone or an important magical artifact- but for some reason, Britannia was using all her powers to force Spain to give it back to Portugal. Finishing the bag of chips, Ruri sipped a soda and opened up one of the ramen packets. Mixing it with a cup of hot water she made with her nearby water heater, she began to slurp the noodles.

“Now Britain is trying to force the Orange Princess and Spain to give her some of their jewels from the Western Indian islands. Isn't she ever satisfied? How greedy of her.” Rapidly consuming the last of the noodles, Ruri began eating one of the bentos. She was already feeling pretty full, bu she knew she couldn't stop now. This was where it was going to get hard- she'd have to force herself to eat more than she was comfortable with if she wanted to gain a bigger capacity for eating. “Otherwise, I'll never be able to put on a single pound,” she thought.

Twenty minutes and four dishes later, Ruri felt more stuffed than she ever had in her life. Her belly was swollen and pushed considerably away from her waistline. She was thankful she was wearing sweatpants, or else she'd be in even more pain. Weakly starting another episode of the show, she forced herself to chug another soda.

“It will all be worth it. I just need to go through this one stuffing, and I'll be able to eat much more in the future. One night of pain for a chance to grow... and a chance at love.” She stuffed piece after piece of chicken down her throat as she watched Norway flee from her lover, Denmark, only to be caught and forcibly married by the old and ugly Sweden. Each bite felt like an eternity as she forced her tired jaws to chew each morsel. She began to feel dizzy as she got closer and closer to finishing this dish, her last piece of food she hadn't consumed. The blue and red dresses of the anime figures swirled around in front of her. “One... more... bite.” Her hand trembled as she forced the last piece up to her mouth. She bit into it, now finding it to taste disgusting. Her stomach gurgled as she mashed it into bits in her mouth. She wasn't sure if her throat muscles would even be willing to send down one more morsel. Finally preparing to swallow, she slowly and easily pushed it back in her mouth and gulped as it headed down to her stomach. She sat there, bloated and tired, in silence.

It was over. She had done it. She had conquered what seemed to her a mountain of food. Looking at her belly, she realized it was so packed with edibles that it her shirt was beginning to ride up it. She took it off entirely, leaving her upper body clad only in her tiny bra. She slowly and gently rubbed the firm, swollen mass. Her stomach felt so full and heavy that she could hardly breathe. She was in agony... and yet, at the same time, she felt a sort of pleasure in her discomfort. She wasn't sure why, but her inability to move through her gorging made her feel good.

“Is it because I'm doing this for love?” Ruri thought. “That might be it. Then again, I didn't think a fat girl could ever be attractive either, and yet here I am trying to become one. Perhaps there are pleasurable sensations that I'm only just now becoming aware of.” She managed a slight grin as she began to grow drowsy. The treats she had packed away were sending her into a slight food coma. The smiling girl fell asleep right there at her computer with a hand on her taut and round belly.
**************************************************************************************************************************

Saori looked at her watch. “It isn't like Miss Kuroneko to be late,” she thought. The tall girl was currently sitting in their traditional meeting place, a cafe in Akihabara, waiting for her fellow otaku to show up. Her and Kuroneko were set to eat here, then go check out the nearby cosplay shops to look at the new designs of released outfits. Though both Saori and Ruri made their own costumes- Saori because she was so tall, Ruri because she was so poor- they both liked to see what the latest trends were.

The bell on the door jingled as Ruri stepped in. She was currently carrying a double-scoop ice cream cone, licking it contentedly as she walked over to Saori.

“Ah, hello, Miss Kuroneko!” Saori stood up to greet her. “How are you this fine day?”

“M-miserable, of course.” Ruri realized how happy she had looked, and quickly wiped the smile from her face. “It's not like there is anything different about reality today... we're still just the pawns of fate, dancing to the tune of the underworld.” Saori chuckled at her obvious attempt to save face.

“Ah, if you're eating ice cream, then there's no need to stop to eat here, is there? I'm not really hungry myself, so we can-”

“But... Oh, I'm actually somewhat hungry,” Ruri replied. Saori raised an eyebrow at this, glancing at her ice cream cone, causing Ruri to blush. “I-it's not that big... and I didn't eat breakfast anyway.” This was a lie, of course. Ruri hadn't skipped a single meal in the four days since her stuffing, and indeed, had usually tried to eat extra meals.

“It's not problem, Miss Kuroneko. Saori sat back down, followed by Ruri. “Eat what you want here, and then we'll head out. We have plenty of time, after all. A waitress, dressed in a maid costume, came to their table.

“Are you two ready to order, or would you like some more time?”

“I would like two orders of omelet rice, if you would.” Ruri handed over her menu. Saori merely asked for water, and the waitress left.  Looking at her tiny counterpart, the glasses girl sighed.

“TWO orders of omelet rice? They are pretty big here, you know.” Saori, despite her humorous appearance, was no dummy. She had seen what had happened to Kirino, and it hadn't taken her long to figure out why. “Tell me, Miss Kuroneko, are you trying to go down the same path as Miss Kirino?”

“What do you mean by that?” Ruri's face grew slightly flushed as she nervously and hurriedly licked her ice cream.

“I'm asking you, Miss Kuroneko,” Saori said in a serious voice. “...Are you intentionally attempting to gain weight?”

“H-how could you even ask that?” Kuroneko was now eating her ice cream in whole bites, rapidly causing it to diminish. “You think that I would ever want to be like that whale of a girl? T-that's completely ridiculous! I-”

“Miss Kuroneko.” Saori cut her off, her face deadly serious. “I am your friend, so please do not treat me like a fool. I was not oblivious to why our friend, Miss Kirino, grew so large. That was her decision, and I saw no reason to comment on it. But in your case, I think I need to. You are trying to change yourself in a major way for a chance that might not pay off. With the two of you competing like this, I seriously worry that one of you is going to be left very hurt and bitter, not to mention the aftereffects on your body. You need to understand exactly what you are getting into before you embark on something major. Do you get what I am saying?” Kuroneko nodded her head, looking slightly downwards.

“T-thank you, Saori. I am... glad that you are so willing to give me good advice. And I understand that there is a competition between me and her and only one can win... but I am willing to accept the consequences. I am not going to give up, no matter what the price might be.” Saori smiled.

“Oh, to be young and in love.” She chuckled. “Very well, I won't stop you. But please, if you ever need help or to talk to someone, I am here for you.” The waitress returned at that moment with Ruri's food. After she walked away, they sat in silence, Ruri still looking a bit downcast. “Well, what are you waiting for?” Saori demanded. If you want to fulfill your goal, I suspect you're going to need both of those rice orders. Ruri picked her head up and smiled. Done with her ice cream, she immediately began shoveling the rice in her mouth at a pace that showed that her stuffing had definitely paid off. With her breakfast and the ice cream still in her belly, the fact that she could eat such a large lunch showed that she was capable of packing way a lot more than she had been a few days prior. Saori grinned as she sipped her water.”Goodness,” she said quietly. “If you and Kirino keep eating at this pace, it won't be long before I'm the small one in the group.”

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

“I've been making pretty good progress.” A week after the cafe meeting, Ruri was checking out the effects that her constant eating was beginning to have on her body. Kirino's advice had indeed worked wonders. After that first night, she was finally able to pack away enough to outrun her metabolism, and even more gorging seemed to have enabled her to consume even more. Standing in her room, clad in her bra and panties, she viewed herself in the mirror. Her belly had definitely changed in size. Though it was by no means big, and nowhere close to Kirino's bulging gut, Ruri was able to feel a newfound softness as she gently stroked it. She stood sideways and noticed that it had just slightly begun to creep outwards over her panties, though it still firmly refused to even begin a downward hang.

“My breasts are just as small, though...” Indeed, her tiny boobs had remained unchanged. She was hoping they would at least begin growing to a respectable size, but alas, they firmly refused to lose their cute and petite status. However, her rear seemed to have made up for it. As she looked over her shoulder at it in the mirror, she lightly poked it, noticing that it now had a good layer of flesh covering her previously bony bottom. Her panties had been getting a bit tight too, come to think of it. She noticed, as she stood in profile, that she was beginning to develop actual cheeks on her butt- there was a slight crease in her flesh between her legs and the twin collections of fat. “The weight is mainly going to my middle and rear... am I destined to have a body like Kirino?” The thought made Ruri ponder the situation. She had hoped, like in her drawing, that she would develop more of an hourglass figure for Kyousuke's pleasure. But then again, Kirino's body wasn't bad at all, was it?

“Even if it's mainly hit her elsewhere, her boobs are a nice size... and the rest of her is so... so...” Ruri wasn't sure what the word she was looking for was. Fertile? Womanly? Sexy? Her wide hips certainly were those of an ancient goddess of fertility, and her bottom-heavy appearance truly was hypnotizing to watch in motion. Ruri imagined herself as a 250 pound pear. Her rear end would be so luscious and juicy that everyone she passed by would be forced to watch it jiggle and sway as she walked down the street. She would dress much more respectably than Kirino, of course, and wouldn't ever stoop to the level of attention-seeking that the orange-haired girl did... but then again, with an ass like that, it wouldn't be her fault if people gawked, would it? She placed her hand on her belly again, trying to see what it would look like in her mind at Kirino's size. Large and imposing, it would bulge and hang over her shorts. She'd have to greatly extend the amount of fabric in her cosplay if she ever wanted to cover it... but the again, if she was around Kyousuke, maybe it would be okay to leave it slightly exposed. “A-after all... with his perverted tastes, maybe he'd like to... rub it.” She envisioned herself sitting on a bed as her boyfriend played with her soft middle. His hands were gentle yet firm, maneuvering and wobbling her pale flesh. He patted it slightly and watched the wave of motion travel though it. He then began to slowly lift up the rest of her shirt, beginning to expose her bra. His hands reached towards her fattened breasts, and...”

“Gah!” Ruri's eyes flew open. “What am I doing, having such... indecent thoughts?” She shook her head. It was still too early to think of such things. In fact, as she walked over to a scale, she was about to see just how far away she was from this ideal. As she stood on it, the previous measurements from her last weigh-in a month ago popped up. “95 pounds. Goodness, I really am a tiny girl.” She waited in anticipation as the scale calculated her new weight, hoping that she was, perhaps, slightly less tiny. The number flashed on the display.

“108 pounds. Disappointing.” It was the first time in her life she had ever weighted three digits, but still, she felt as if she had hardly grown at all. “Well,” she said out loud, a smile coming to her face as she opened a candy bar she had nearby, “I guess that means I'll just have to eat more.”

She took a large bite.


Kirino and Kyousuke both furiously pounded on the buttons and wiggled the joysticks on the arcade machine they were currently playing on. One the screen, the characters of the two were punching and kicking each other rapidly. A sequel to the loli fighting game that Kirino was so fond of, Siscaly 2: Imouto Boogaloo was one of the top draws of the arcade.

“Ugh!” Kirino, never very good at fighting games, was growing frustrated. Her body quivered as she mashed the buttons. “Are you cheating, Kyousuke? You shouldn't be able to dodge so many of these attacks!”

“Hey, don't blame me for being good at the game. You forced me to play the first one so much that I couldn't help but learn.” In fact, Kyousuke was goon enough to beat Kirino despite his disadvantage of positioning. Because the machine was somewhat narrow, Kirino's wide lower body was crowding his personal space. Her hips and soft upper legs kept rubbing against his, forcing him to stand awkwardly.

“Stop kicking me while I'm recovering!” Taking advantage of her size, Kirino started swinging her lower half against her brother, using her hefty booty as a battering ram. Each collision made her huge ass shake as it bounced off of him. Quickly losing his concentration, both from the destabilizing of his balance that hundreds of pounds of imouto were causing and the heavenly feeling he got from so much softness touching him, Kyouske's movements grew sluggish. Kirino saw her chance and activated her character's special move.

“OLEV BEAMU!” A pink ray shot from her character's chest, shattering the health bar of Kyousuke.

“Woohoo! I won!” Kirino raised her hands in victory, causing her already too-short shirt to rise up even higher, exposing her entire belly to the world. As plump as ever, the tan ball of adipose revealed that Kirino was still eating very well. Her brother, trying to preserve her modesty, yanked it back down.

“Geez, you really should be wearing some bigger clothing Kirino.” She glared at him and crossed her arms, leaving them lying on top of her bulging gut.

“Why? Are you saying you don't think I look good or something?” He grimaced.

“I'm not saying that at all! I just think that you shouldn't try and show off so much flesh.”

“Hmph! Not my fault that my clothes can’t handle all of me. And it's not like I'm ashamed of my body or anything.” Looking nervous, Kyousuke changed the subject.

“Kuroneko should be getting here soon. It's been a while since you've seen her, hasn't it?”

“Yeah, she's been pretty busy for the last month. I don't know what's been happening, but at least she was finally free to shop in Akihabara with me today. I-” Kirino stopped talking in shock as she saw Kuroneko approaching. Though it had only been a month, the girl looked vastly different than she had previously, occupying a lot more space than she used to. Though Kuroneko was heavily clothed in her traditional cosplay as the Queen of Nightmare, it was obvious that the body beneath had undergone drastic change. The black fabric of the dress could not hide the sizable tummy bulge Ruri was now packing in front, nor could it conceal its bouncing as Ruri strode forward. Even more shockingly, her breasts were now visible as well underneath her clothing. Though their growth seemed to have been slight, it was still the first time her chest had ever enjoyed any sort of prominence. Her legs, too, had plumped up. Though her skirt fell down below her knees, the reaming length between it's bottom and her shoes, covered only in her long socks, was proof of this. Her calves had grown much thicker and meatier, belying even more hidden growth. “How big is her butt now, I wonder?” Kirino thought.”She must be over 150 pounds by now. That's even faster than I was able to grow!”

As she reached them, Kuroneko smiled at Kyousuke. “Hello, senpai. I didn't know you'd be coming with your sister today.”

“Oh, well, I was able to free up some time at the last minute. I assume you don't mind me being here?”

“I will just have to put up with it. So long as you can control yourself and not say anything too foolish, I can see myself managing it.” Ruri glanced at Kirino, who still was slightly stunned. “What's wrong, Kirino? Are you not feeling well?”

“N-no, it's nothing! Are you ready to get going?”

“Indeed I am. We shouldn't stand around and waste time, as the shadows of our mortality creep ever closer.” With that, the black-haired girl turned around and began leading the way. Kirino now got a view of how much Ruri's backside had changed. While it was clear that Ruri had many considerable alterations all over her cosplay to fit her larger body- the remains of tears and stitches were proof enough of that- the majority seemed to have been made in the rear. Yet even now, her wide behind looked ready to cause some more damage. It boisterously jutted out behind her, threatening to overwhelm the fabric that was struggling to keep it covered. Each plump cheek's outline was visible as they moved up and down, jiggling and swaying, as she walked with her hips swinging. Self-conscious all of a sudden, Kirino put her hands on her own rear end.

“Well I'm definitely still larger there,” she muttered to herself as her hands sank slightly into the soft flesh. She looked sideways at her brother, whose eyes were clearly on Ruri's rear end as well. “You idiot. Why didn't you tell me how much she had grown?”

“Huh? Well, I mean, I noticed it at school, sure, but it's not like it's something you'd just talk about, is it? She has gotten pretty big, though...” His eyes seemed to slightly glaze over as he again stared at Ruri's bottom. The growing girl turned around and smiled.

“Coming, you two?”

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

The day seemed to fly by rapidly as the three of them explored the nooks and crannies of Akihabara. They stopped at stores selling anime and manga, arcades, and more than a few eateries. Indeed, for Ruri and Kirino, food seemed to be the major factor in their day. Both of them were consistently consuming, buying calorie-heavy treats at every opportunity. The girls' midsections swelled as the day grew longer, growing more and more filled with all sorts of delicious morsels. Near the end of their trip, as the sun began to set, both of the hefty girls found themselves facing each other across the table at a McDonelb's, eating yet another meal, while Kyousuke sat outside, taking a phone call. Sated, and a bit bloated, from their gorging, the two otakus breathed heavily as they gently rubbed their stuffed tummies.

“Whew... you look a bit tired, Kirino. Considering that you didn't even eat as much as I did today, I'm a bit surprised. I guess you aren't quite as gluttonous as I had thought.”

“What are you mumbling about? I ate way more than you did, you twig. Don't you remember the yakisoba stand? I had three and you could hardy eat two.”

“Considering that I had just eaten a tripe-scoop ice cream cone, while you had abstained from anything more than a single scoop, I don't think that should be surprising.” Kirino glanced over Ruri's larger body in response.

“Just when did you start growing so big, anyway? It was only a month ago that you were over at my house, and you were just as tiny as always then.” Ruri grinned in response.

“Ironic, isn't it? If you recall, just a few months ago, we were both in Akihabara, across a table, discussing how YOU had managed to increase your girth. Though, if I remember correctly, your weight was around 168, which makes me,” she lightly patted her bulging belly, “a bit bigger.”

“Well... how much do you weigh, then?”

Kuroneko slowly sounded out each word. “One-seventy-one. Really, it's extraordinary progress any way you look at it, but I still don't feel satisfied. Maybe once I put on another eighty pounds or so, I'll be ready to slow down.” Her cute face cut an image of smugness as she eyed Kirino's worry look. “What's the matter, Kirino? Didn't you say just a month ago that I couldn't ever hope to look as good as you? Or are you now realizing that I can pull off looking good with a larger form just as well as you can?”

“Worried? Me?” Kirino laughed nervously. “I don't know what you're talking about. And besides,” she put her hand on her gut, which was currently jutting into the table, “you're still way behind me. Do you know how big I am now? I just weighed myself this morning, and the scale said I was 253 pounds. That means I'm two and a half times my original size. I'm huge! I have to order all of my clothing from America now, since I've outgrown the clothing sizes in stores here. My belly hangs over all of my pants, and it's harder every day to fit myself into booths at restaurants. And have you ever seen a bigger booty than mine? It's gotten so big that my ass overwhelms chairs when I sit in them and part of it hangs over the edges. Every time I sit down, I hear them creak and I wonder if I've gotten so fat that the chair will break! Believe me, Kuro,” Kirino leaned back as far as her fleshy body could maneuver, “I'm the real fat girl here. The only reason my gain has leveled off is because I wanted to stay at this size. But if I'm ever in danger of losing the mantle of  'biggest girl...' well, let's just say that I still have plenty of room to grow.”

It was now Ruri's turn to look nervous. Kirino's open admittance of her hugeness had caught her off guard. “You...” She stuttered. “You think you can win his affections so easily? I assure you, I won't allow myself to be beaten by someone who has such bad taste that she thinks that Prussia is the best character in Vienna Girls!” They both stood up and glared at each other over the tables, their bulging bellies facing each other.

“Hey guys, done with my phone call!” Kyousuke walked in right at that moment. “Geez... why does the atmosphere feel so tense in here?”

“Nothing important, senpai. Your sister just refuses to admit that she will soon be the lesser of the both of us.”

“Hah! More like you just aren't acting like a very big girl is all!”

Confused about what they were talking about, Kyousuke nervously rubbed the back of his head. “Well... are you two ready to head out? It's starting to get late.”

The two girls both broke their eye contact in tandem. “Hmph!” They walked towards the exit, both passing Kyousuke on the way to the door. He eyed both of their jiggling rumps as they swung their hips. The sight of both the big girl in cosplay and the even bigger girl in her skimpy clothing walking with an angry gait left him confused.

“Girls sure are weird,” he thought to himself.

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

“Ugh! Fit, you wretched clothes!” Ruri was in her room at home in a bit of a dilemma. She was currently trying to put the skirt of her school uniform on, but her girth simply refused to permit this. No matter how hard she yanked, she couldn't get both ends to connect. Her hips were simply too wide. She gave up, letting the article of clothing fall to the floor. Looking at herself in her mirror, she sighed. “At least I got the shirt on.”

Of course, she had barely accomplished that. She had long since outgrown the white shirt that she wore underneath the heavier overshirt, and it would have left the lower half of her belly, and just a bit of her navel, exposed if she had worn nothing else. Yet the overshirt itself was under intense stress. Each of the two buttons visibly were straining to hold back her bulging gut, serving as dams against a tide of soft, pale flesh. A gap was forming between them, leaving a tantalizing hint of fat visible, her generous middle simply refusing to hide. She turned around to look at her current worst enemy: her abundant rear end. Covered only by her panties, which were thankfully large enough to cover it, it was obvious that Ruri was packing some serious junk in her trunk. Huge and squeezable, her ass was growing to be the most visible part of her already big body. The short girl hesitated before lifting up one of her heavy cheeks slightly. She released it and watched it fall, causing her booty to quiver and bounce.

Just as her shyness was covered by her sharp tongue, so Ruri's seeming pride in her gain covered deeper anxieties. She might be gaining for the sake of love, but that didn't make such a major adjustment in how she lived her life easy. Already ostracized at school, the glances of disgust she now received did wound her, no matter how well she might hide it. And her new form was harder to adjust to than she had thought. Her rapid gain had caused her to grow twice as heavy within one month, and all of her soft and luscious flesh now made it much more difficult for her to maneuver her body in the same fashion. She was still learning how to handle all of herself, from her jiggling belly, whose shaking when she walked still disconcerted her, to her fat derriere, which had developed a dangerous tendency to knock things over.

“Hey, big sis...” Ruri jumped, sending a ripple throughout her expansive form. Her youngest sister had opened her door and stood there holding a pillow.

“Tamaki! What are you doing? Why aren't you asleep?” She had put both her sisters to bed over an hour ago.

“I had a bad dream... can I sleep with you tonight?”

Her soft spot for her sisters kicking in, Ruri had no choice but to consent. “It's fine. You just startled me, that's all... I don't have an extra mat, but you don't mind sleeping in the same one as me, do you?” Her sister shook her head. “Go ahead and get in, I'll be going to bed now too, then”

Ruri unbuttoned her school uniform as her sister got into the mat. She then removed the undershirt over her head, which, tight as it was, resisted by hanging on to her wide middle. A final yank pulled it off, dropping all of her gut's flesh glory back down. She heard a giggle.

“What are you laughing at, Tamaki?” Ruri smiled at her cute sister.

“You're so big and bouncy now, sis!” Ruri's face grew flushed. She still wasn't comfortable with her size being pointed out so blatantly. She quickly flicked the light switch and got into her mat, wearing her typical combination of just a bra and panties to bed. While her size greatly reduced the spare room, and thus her abundance would have naturally touched her sister, Tamaki seemed not to mind. In fact, she giggled again as she hugged her sister's belly, making Ruri give a slight squeal.

“T-Tamaki, what are you doing?”

“You're so soft, Ruri! It's like a big stuffed animal!” The young girl nuzzled her face in Ruri's belly fat, causing the older girl to laugh from the sensation.

“H-hey, calm down! I'm pretty ticklish there!” Both of them quietly laughed together as they embraced. “So... you don't think I'm getting ugly”

“Ugly? I don't get it”

“Well... I've gotten pretty fat. Most people would say that I'm getting ugly because of it.”

“But your face is the same. And your hair hasn't changed either. What would be ugly?”

Ruri blushed. “My... Well, you don't see that many people with a big belly like I have, for instance. Most people don't like it when girls aren't thin.”

“But your big belly is so fun to play with. It's soft and squishy. Why would something so nice to touch be ugly? And besides, if you get fatter... all that means is that you're becoming an even bigger sister!”

“The innocence of a child,” Ruri thought. “Thank you, Tamaki. So long as you don't mind it, I won't care what anyone else thinks. But I hope you don't mind if your big sister becomes even bigger. I have a feeling I'm going to put on a lot more weight.”

Tamaki's face beamed. “Then you won't be my big sis! You'll be my huge sis!” Ruri laughed again, sending her belly jiggling, which only served to enthrall her little sister even more. The two remained clutched together in a warm embrace as they drifted off into sleep.Ruri felt an increasingly familiar warmth flood across her lap as she took a seat on Kyousuke's bed. She looked down and smiled as she viewed how her belly bulged out of her tiny shirt, covering her upper thighs. Taking advantage of the unusually casual clothes she was wearing, she lifted up her shirt to completely expose all of her thick gut. She gave it a few pats, enjoying how the feeling of plushness felt against her fingertips.


“Goodness. I'm really getting big.”

And so she was. Just two week after her nighttime discussion with Tamaki, Ruri had managed to pack on another twenty pounds of luscious fat, putting her only nine pounds away from 200. Now that she had officially doubled her girth, and after her younger sister had bolstered her confidence, the beautiful otaku was truly beginning to enjoy being large. After having such a slight body her whole life, she was growing addicted to the constant sensations her new body was giving her. The feeling of  bulging out of clothing, of having chairs creak beneath her weight, of having her whole body shake as she walked-- all of these new experiences excited her. She leaned back and reclined on her crush's bed, amused at how much of it her soft form occupied. Rubbing her tummy, she recognized that this must be how Kirino felt as she had grown large.

The door burst open, and Kyousuke walked in. Both he and Ruri stared at each other in shock, momentarily stunned. As Kyousuke took in the sight of his junior's fleshy and fully exposed gut, her face flushed. She leaned up as quick as she could and forced her shirt back down.

“Senpai, you idiot!” Less than a second later, the pillow on his bed collided with his face, thrown by the embarrassed young girl. “How dare you barge in here like that!”

Kyousuke rubbed his cheek, reddened by the pillow. “It's my room! Why should I have to apologize? Why are you even here?”

“Your mother let me in... I heard you were out with your friend, so I was going to wait here for you... But I didn't expect you to come back so soon!”

It was only then that Kyousuke noticed what unusual attire she was wearing. Neither cosplay nor her school uniform, Ruri was clothed in a tanktop with white and purple stripes along with pink shorts. This change from her traditional style of dress left a significant amount of her pale flesh exposed, both from her uncovered arms and much of her legs along with a thick ring of belly fat that impetuously refused to remain constrained. “But why did you come over? Is there a problem?”

Ruri's face turned even redder. “N-no, I was just hoping that I might work on the coding for the latest game me and Sena are working on. I thought I might allow you to enjoy my company while I was doing so, but if you are going to be ungrateful...”

“Hey, hey, it's fine. I was just surprised, that's all. I've got to do some homework, so you can feel free to code on the bed while I work at my desk.”

“Very well. That sounds satisfactory.”

Both of them set up their laptops and began work. After a short time, however, Kyousuke found himself growing distracted by the girl. As she seemed absorbed looking at her screen while typing, he found it easy to sneak peeks at her. Though he had watched her balloon over the last two months, it was only now that he saw her in more revealing clothing that he truly was able to become aware of all the changes in her body. His eyes followed the contours of her curvy form as she laid on her stomach, moving from her snow-white neck to her big, soft rear. The tightness of her shorts enabled him to make out the fullness of each cheek, and he began to think about how malleable its would be if he grabbed a handful of it...

“Stop it! I can't think of her like that! She's just my friend!” Kyousuke furiously screamed at himself inwardly. He went back to his work, diligently solving each problem. Yet just a few minutes later, he felt his eyes wandering again. He stared at the exposed portions of her love handles and tried to remember what he had seen when he had walked in. He imagined how soft her belly was, how deep he would be able to sink his hand into it if he rubbed it, how much it would jiggle when she walked, how-

He realized that she was staring directly at him.

“Oh my, senpai. You seem to have found something much more interesting than your homework.”

“I- I-” Kyousuke began to sweat as he took in the gravity in the situation. How long had she seen him looking at her body? Had she known the whole time? Was she just toying with him?

Yet for all of Kyousuke's nervousness, Ruri was inwardly panicking as well. “As I hoped, he definitely was looking at my body! Don't screw this up, Ruri, you need to follow up exactly as you planned.” She managed to keep her rapidly beating heart under control as she sat up and leaned back against his wall, her slightly rounded face looking contended. “One more hook, then give him some time to recover,” she thought. She lifted her shirt up, exposing all of her vast gut, causing Kyousuke's eyes to bulge out. “I'm feeling really hungry, senpai,” she moaned in a sultry voice as she slowly rubbed her middle. “Get me some food, will you?” She smiled at him as she gave her impressive belly a harsh slap, sending a wave of motion through her rolls as the smacking sound reverberated throughout the room.

“R-right away!” Kyousuke stood up and dashed out of the room, eager to escape his embarrassment. Ruri giggled at her crush's eagerness to serve her. Yet she quickly grew serious as she contemplated what to do now. She massaged her belly to ease her nervousness, enjoying the comfortable softness. “I've been planning this all week. Nothing can go wrong. I'll just let him cool down while he gets me my food, then I'll catch him off guard by asking him on a date. I can be certain now that he loves me being this big, what with the way he was staring at my fat.” She grabbed hold of one of her many rolls to reaffirm to herself how huge she was. “I think I've grown to  love being heavy as much as he likes me being this way.”

She began to fantasize about growing even bigger and fatter with the help of Kyousuke. Closing her eyes, the vision of a peaceful beach appeared before her. As the calm waters of the ocean made gentle waves, she rested on the warm sand, lying on her side in a rather skimpy black swimsuit. Kyousuke was next to her, feeding her a cluster of grapes like she was an overfed Greek goddess. Even fatter than she currently was, her 300 pound form was bulging and pouring out of the tight swimming garb in every way it could. Though her breasts were proportionately small, her overall enormity still kept them sizable, barely contained by her bikini. Due to her sideways position, her huge belly spilled over and hung downwards, pressing heavily on the sand, leaving an indent. Kyousuke was skillfully manipulating her tummy fat, maneuvering its rolls and folds like clay, lifting and dropping it, sending quakes throughout her body. Ruri imagined how colossal her rear end would be at that size. She visualized it as two swollen cheeks, each carrying huge amounts of soft fat. Her bikini, overwhelmed by the mountainous posterior, could barely cover even a third of her huge booty. Thick and wide, one could only imagine how much it would sway and jiggle as she moved. Ruri imagined the fantasy version of herself sitting on her crush's lap, covering his body with her weight. She would take pleasure in how it made him both aroused and caused him discomfort, how he would struggle to breathe as he embraced her squishy form, how he would heavily pant as he patted her belly, how-

Ruri opened her eyes suddenly, her face red, as she heard Kyousuke coming back up the stairs. She quickly composed herself as he walked in. He carried a party-size bag of chips alongside another equally-sized bag of cookies.

“So much food, senpai! I guess you don't mind that I've been putting on a little weight, then?” she purred as she patted her belly for emphasis.

“Oh, uh, have you? I guess I hadn't noticed.” As he placed the bags of goods down on his desk, Ruri noticed the drops of sweat on his face. Clearly, he desired to avoid such an awkward subject.

Silently taking a deep breath to disguise her nervousness, Ruri lifted her bulk up from the bed and faced her crush. “You may be oblivious, senpai, but you can't possibly be so stupid as to have not noticed the rather... massive changes I've gone through recently. She walked towards him, her broad hips swaying gracefully. He nervously moved backwards until he found his back against the wall. This didn't stop Ruri, who stood so close to him that her belly squished against him and held him in place. The height difference between the two made her tilt her head up to look him in the eyes.

“After having watched Kirino grow so big, surely you must have noticed when the same things happened to me. I'm overeating all the time, and ever bite means more inches and pounds of lovely flesh on my body. Can't you feel how fat my belly has grown, senpai?” She grabbed his hands and forced them onto her sizable love handles.

“Kuroneko, I-”

“Shhh.” She silenced him with a gentle voice. “Maybe you noticed my chest was getting bigger?” She looked down at her breasts. “Granted, they have had the least amount of growth, but still, a pervert like you would have noticed how they've been much more visible lately. Surely you've taken a few peeks at them bouncing while I walk?”

“K-”

She put a finger to his lips. “Well, there's no way you could have missed this.” She backed away from him and turned around, her tight shorts and big booty on full display. She looked over her shoulder at him and smiled as he stared at her rear with huge eyes and a slightly open mouth. “By the look on your face, I guess you have noticed. It would be hard not to, though. My butt has gotten huge. Not as big as your sister's, but I'm presenting a real challenge to her, aren't I?” She placed a hand on one of her cheeks as gave it as gentle squeeze. “I suspect it will get a lot bigger if I get fatter, though. I might need two chairs to contain all of its abundance if I don't stop eating so much.” She turned back around, again pushing herself up against him. “But I just can't help myself, senpai. Food just tastes so good nowadays. There's nothing I love better than eating, and I find myself doing it all day long. I finish a meal and immediately want more. I'm becoming so greedy, aren't I? But you're still willing to be friends with me... It's very nice of you, senpai.” Her playful demeanor began to give way to her shyness. She looked down as her face grew red.

“This is it...” She thought to herself. “I'm going to ask him on a date with me. I have him stunned, there's no way he'll say no! I just have to say this one thing, and that will be it!”

“S-so that's why, senpai...” She twiddled her thumbs together. “Would you be willing to... Willing to...”

“WOULD YOU GO ON A DATE WITH ME?”

Kuroneko looked up, shocked. Had she said that? It didn't sound like her voice. It took her a second of looking at Kyousuke's desperate face to realize that it had been he that asked the question.

“What?” she asked.

“Would you go on a date with me this weekend?” Kyousuke's eyes were shut as he rambled off his semi-confession. “We could go to Akihabara together, just you and me. Whatever you'd like to do would be fine with me, if you would just be willing to go.”

Ruri recovered from her confusion. A sweet smile appeared on her face as her true personality shown forth. “I... I would be happy to, sen- I mean, Kyousuke.”

They both stood there, starting into each others' eyes. Eventually, she stepped back from him, letting him escape from between the wall and her fleshy girth. “But for now...” She grabbed the two bags of snacks and sat herself down on his bed again. “There's no point in letting all this food go to waste. You wouldn't want me going hungry, would you?” She again lifted her shirt slightly upwards and began rubbing her lower belly. “In fact, maybe you could feed these to me. Do you like the idea?”

They boy's head feverishly nodded up and down.

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

Three days later, Ruri found herself awaiting Kyousuke at the McDonelb's the previous outing had ended at. Out of both hunger and anxiety, Ruri was stuffing her face with the goods that covered over a quarter of her booth's table. Leaning forward to grab another french fry, she noticed with some pleasure how her belly pressed into the table. It wouldn't be long before her corpulent form would be pressing into it all the time. Indeed, just this morning she had been pleased to find her weight at a rotund 197 pounds. Besides her obvious goal of increasing Kyousuke's attraction to her, her other primary motive on the date was to pass the 200 pound milestone in his company.

Kyousuke walked in and noticed her before she saw him. Absorbed as she was in gorging, he wasn't surprised. He already had experienced firsthand at home how hard it is to get the attention of a fat girl away from her food. Just last night, Kirino had knocked him over with a swing of her heavy lower half while eating a candy bar, and had just kept right on walking as if nothing had happened.

“She looks awfully cute,” Kyousuke thought. Scorning her traditional cosplay, Ruri today was wearing her white sundress that he had seen her in a few times. Since it was a hot day, it was good she was wearing something light, though it left plenty of her flesh exposed. He ran his eyes over her arms. He hadn't noticed before how big they were getting, but like every other part of her, they had grown thick and swollen with fat. Even her dainty fingers were plumping up, he noticed. He was also able to see some of her exposed legs and how they spread out over her side of the booth.

“Hello, Ruri.” She looked up, her mouth still filled with food. She quickly swallowed.

“H-hello, Kyousuke.” Both of them smiled at being called by their names. “I'm sorry that I have all this food here. I'll throw it away so we can get going.”

He shook his head and took a seat on the opposite side of the booth. “There's no need. You looked like you were enjoying it. And I wouldn't want you to get hungry while we're walking around.” Ruri needed no other urging and again began to rapidly consume her bounty. Kyousuke watched, amused, as she ate like it was her final meal. “I'm glad she can get some enjoyment out of eating,” he thought.  “She seems a lot more happier with food constantly in her hands than she used to. Not that I don't like the other effects, too.” He glanced at her upper belly and how it kept pushing into the table.

“So where did you want to go first?” he asked. She took a break from her food frenzy to respond.

“I'm quite alright with anything... so long as you're with me.” Her face grew red.

“How about we go look around at some discount manga? I saw a place last time right next to a good-looking yakisoba stand, so we can get you some of that, too.”

“Oh my. He's really trying to fatten me up, isn't he?” she thought. “I'll only be too happy to oblige.”

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

Three hours later, both Ruri and Kyousuke were having the time of their lives. Being alone in each others' company, with both of them knowing that it was a real date they were on, was a thrill. Every activity they engaged in, from playing arcade games together to looking at cosplay for Ruri to get ideas for what to make for herself, took on a new magic. Ruri laughed far more often than she normally did, and Kyousuke served to be extraordinarily attentive to her. Every place they went, he managed to scrounge up the money to buy food for her, ensuring that she was kept sated.

“In fact, I'm beginning to feel rather full,” she thought to herself as they walked down the sidewalk, her left hand clasped in his right. She put her free hand on her belly, feeling it. While it maintained a thick layer of plushness, it was definitely less yielding than normal. She looked down and watched it as she walked. “It's even bouncing less than it normally does.” After over a month of stuffing herself and stretching her stomach, she had almost forgotten what it felt like to be full.

Kyousuke looked at her. “Something wrong, Ruri?”

“Not at all, Kyousuke. I'm having a wonderful time.”

“So am I. Oh, how about we pop into that ice cream parlor over there? That will only be your third ice cream today, how about it?”

“Umm...”

Kyousuke wasn't going to take no for an answer, and led her inside. He wrapped his arm around her as they stood in line, letting his hand sink into her fleshy side. Once they got to the front, he ordered her a triple-scoop cone. Her eyes lit up as soon as she saw it. Full or not, no self-respecting fat girl was going to refuse ice cream. As they sat down, however, a familiar form walked into the story. An especially large form, for that matter.

“Kyousuke?”

“Ayase?”

There stood Ayase Aragaki, Kirino's best friend and Kyousuke's sometimes-crush. Dressed in her casual, form-fitting clothes, it was easy to see that she had been eating as well as Kirino had. Tipping the scales at over 230 pounds, Ayase's girth immediately caused Ruri to feel a twinge of jealousy. Unlike Ruri or Kirino, Ayase's boobs had taken a large amount of her weight gain. The two mounds of softness were currently jutting out provocatively, creating a large amount of visible cleavage. The other major center of her growth was her belly, giving her massive mammaries a nice resting place. Since she had willingly chosen to get fat to be more like Kirino, she too felt no shame in her size, leaving a good amount of her lower belly exposed. Ruri watched it bounce and sway as the girl approached the two lovers, self-consciously rubbing her smaller tummy. Ayase turned a suspicious eye on Ruri as she reached their table.

“Ah. Gokou-san, wasn't it?” Ayase and Ruri had met only once before, and the meeting between the ardent otaku and the obsessive moralizer hadn't gone well. “You're considerably bigger than the last time we met. Have you embraced the beauty of the fuller form, like Kirino and me?” She crossed her arms beneath her breasts, causing them to bulge out tantalizingly.

“It was an independent decision on my part. Though from what Kirino told me, you seem to have merely followed her example slavishly.”

“Just because I'm more voluptuous than you is no reason for you to be jealous. It's unattractive.”

Kyousuke felt the dangerous tension in the air. “Now, now, both of you. Calm down. Ayase, why are you in Akihabara? I wouldn't think you'd enjoy much the place has to offer.”

She looked back to him. “Keep it a secret, but I was actually here to buy Kirino a gift. I think I accidentally hurt her feelings when I dismissed one of her eroge last week, so I wanted to make it up to her. I'm more surprised to see you here without Kirino, though. Does she know you are here with her friend?”

“Er...” A drop of sweat ran down Kyousuke's face. “I hadn't really told anyone. I-” Ruri interrupted him.

“I don't see what business of yours it is why he and I are here. Nor is it a secret. We're on a date together.”

Ayase was taken aback. “A... date? And Kirino doesn't know about this?”

Ruri smiled. “It doesn't matter if she knows or not. It won't change anything now.”

“Hmph! I see neither of you have the proper respect for Kirino. I'll leave you two alone. I came in here for another reason anyway.” She rapidly turned, her breasts and gut bouncing, and stomped towards the counter, her heavy body making loud noises when her shoes met the tile floor. After ordering four scoops of ice cream, she left the building, both Ruri and Kyouske watching her curvy rear end jiggle as she walked out the door.

“You know...” Kyousuke looked at Ruri. “You could have handled that more tactfully. Now she's gonna tell Kirino that she saw us here.”

“Do you want to keep it a secret, Kyousuke? I had hoped that from today we might...” She looked downwards. “Might become closer.”

He put his hand on her head, causing her to blush. “I'd like to as well. But I would have preferred to tell Kirino myself, rather than have her be told by someone else.”

The two sat in silence for the next few minutes as Ruri gulped down the rest of her ice cream while Kyousuke watched her. It was hard for him to stay worried in her presence. Now that he was finally free to see her in a romantic light, he was starting to find her completely adorable. Just watching her cute face as she happily consumed calorie-heavy treats made him feel at ease. As she finished the dessert, she leaned back and put her hand on her bulging belly.

“I have to admit, Kyousuke, you know how to keep a girl satisfied. I'm completely stuffed after all that you've purchased for me today.” She grinned. “From the way you've been watching me eat, though, I would guess you've gotten your money's worth.”

He smiled back at her, unembarrassed. “I can't help it. You look so happy when you're eating that it makes me cheerful just watching. In fact... would you like to do this again a week from now?”  He stood up, preparing to exit the parlor.

“I think I'd enjoy that very much. I've had a very wonderful time today. However...”

He quickly turned back to her. “However?”

Ruri held out both of her arms to him. “Would you mind helping me up? You've packed me with so much food that I think I might not be able to stand by myself.”


The same night as her wonderful first date with Kyousuke had ended, Ruri stood in her bathroom in front of a scale, clad only in her bra and panties. She was a bit anxious about stepping onto it. She had weighed 197 pounds before the date, but even with all of her gorging, she wasn't sure if she could possibly have eaten her way to over 200 pounds. She would have weighed herself sooner, but she didn't want to cheat by checking before she had allowed the food to digest... that and the fact that she had immediately fallen into a deep sleep upon returning home, a victim of a food coma. Now, a good seven hours since the end of the date, she was ready to test the results.

Before she took a step onto the scale, she looked over her body, contemplating her form. “My girth is starting to get a bit uncontrollable,” she thought as she prodded her extremely fluffy belly. Whereas there had just been more of her during her first hundred pounds of growth or so, her body was having to get creative in finding ways to fit more and more fat onto her frame. A myriad of rolls and folds were developing quite nicely, all of them bulging and spilling out every which way. Like Kirino and Ayase, her youthful body was able to combat gravity very well, and so her belly had only developed a slight and sensual overhang over her panties, just enough to flaunt how big and plump it was. As she peered downwards, she found it amusing that her gut had grown so corpulent that she was only able to see the top half of her feet.

“My breasts are actually quite nice, now.” She gave them a slight squeeze. Still proportionately small, but quite big compared to a skinny girl's chest, they managed to at once give her the appearance of both a small-chested girl and a voluptuous beauty. She looked at the bathroom mirror and turned her body sightly sideways, giving her a view of her most unforgettable feature-- her huge rear end. Ruri groped one of its bloated cheeks, grabbing a handful of flesh. “My panties can barely contain it all... and I just bought this pair last week, too.” She smiled as she gave it a little shake, watching all of the junk in her trunk shimmy and bounce, causing her overwhelmed underwear to ride up even more, exposing a greater part of her mammoth booty. Her new love for her size had led to her becoming especially enthralled with her biggest part. Whenever she sat down and felt how it spread out and overwhelmed chairs, whenever she walked around and grew conscious of how heavy it was as it swung from side to side, whenever it brushed against objects as she maneuvered her bulk, she grew ecstatic at the knowledge of just how big it was. When she was alone and free from potential embarrassment, she loved to peer at it in the mirror, watching it jiggle and bounce. In fact...

From the pockets of her clothing on the floor, she withdrew a pair of cat ears she had been carrying with her. Putting them on, she had the appearance of an extremely overfed cat girl. Again glancing at the door to make sure no one could possibly see her doing this, she turned sideways and began to do the little cat dance she sometimes practiced, pawing at the air while slightly leaned over. The dance sent wave after wave of motion throughout her soft body. Her fat love handles quivered, her big gut bounced, her breasts shook, and her ass looked ready to burst our of her underwear with its quaking. She stopped after a few moments, smiling and blushing at how foolish she looked. There was no other way to describe how that dance had made her look except that she was really, really fat.

“Enough foolishness. It's time to weigh myself.” She at last stepped onto the scale, watching its lights flash as it calculated her weight. She again got a good look at her bulging belly as she looked down. A few second later, it revealed her true mass:

“202 pounds.” Ruri said it aloud, almost unable to believe it. She had managed to pack on five pounds of flesh just from the date's gorging? She instantly felt a rush as she grew fully conscious of just how big she was. She grabbed her belly and lifted it, letting it drop and watching the resulting motion. She swayed her hips side to side, feeling how wide they were. She was becoming a truly huge girl, and absolutely loving it. Her stomach gave a light growl, as if demanding a reward for its hard work. She patted it and glanced once more at her reflection.

“There's no denying it, I'm a big girl... But not big enough.”

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

“See, you can date any of these nine girls in the game! Of course, I always date Yuki because she's so cute and chubby!”

A few days later, Kirino and Ayase were hanging out in Kirino's room after school. The young otaku was still trying to get Ayase to understand why she enjoyed eroge, and was currently showing her a PC dating game that she had been into recently. It just so happened that one of the characters was a plump blonde girl who was always eating and whose shirt constantly rode up to expose her belly.

“Oh! See how when she lifts her arms, her belly button gets exposed? Ah, her tummy looks so soft, I just wanna squeeze it!”

Ayase glanced sideways at Kirino's own middle, currently fully visible. “I'm not sure why Kirino finds such a girl so interesting when both me and her are much bigger and softer already,” she thought. Just as they had done months ago, when Ayase decided to join Kirino in being large and in charge, the two friends always changed into clothes they had outgrown many sizes ago when they were alone together. It was a mutual catharsis for the two-- though neither was ashamed of their bodies, after being fat in a country filled with small people, it was pleasurable for them to look at each others' jiggly forms to reinforce their resistance. They let their bulging bellies, their bouncing boobs, and their ample asses get plenty of exposure in their tiny shirts, which barely went below their navels, and their laughably inadequate shorts, which covered only about half of their cheeks. And, of course, they always kept the room filled with all sorts of calorie-laden snacks to keep their luscious bodies full.

While Ayase certainly enjoyed letting her body free in this private sanctuary, she also got a great deal of pleasure from watching Kirino's plump body wiggle and jiggle. She often found herself growing heated and excited when Kirino playfully grabbed onto her boobs and squeezed them, or squished her belly against Ayase's own, or bumped her with that behemoth of a booty to illustrate her dominance as the bigger girl. She was finding it harder and harder to deny the feelings she had for Kirino. They had always been there, but watching Kirino grow so huge and soft, and then following her example, had had a real effect on Ayase. It seemed that as her body swelled, so did her attraction for her friend.

It was for this reason that Ayase was having so much difficult figuring out what to do about her sighting of Kyousuke and Ruri on a date. Fears of Kyousuke's corrupting influences on Kirino, on how Kirino would handle the news, and on how it might change her and Ayase's relationship all created an air of uncertainty surrounding the matter.

“Kirino, do you think that-”

“AH! Look, her panties are showing when she bends over! See, you can choose whether to look at her underwear or pretend not to see!” In character, she quickly moved her mouse to the “look at her underwear” option and clicked. She then reached over to a can of soda by her computer, opened it, and quickly downed it all in one chug. “Man, that hit the spot!” She slapped her belly in pleasure. Ayase watched intently as the fleshy mass yielded to the sharp motion. It wasn't only because they liked watching each others' bodies that the two gave their bellies plenty of freedom in her room-- the amount of  food and drink that they put away often led to their guts becoming substantially larger due to stuffing and bloating.

“Here Ayase, sit down and try playing it yourself.” Kirino heaved herself up from the chair, which squeaked as if it was thankful to be rid of such a heavy burden. Its trials were not over, though, as Ayase placed her bulk onto its seat-- after all, her body was only 20 pounds lighter thank Kirino's. While Ayase fiddled with the game, she watched Kirino out of the corner of her eye. The fiery-haired girl wobbled her body to a corner of the room where a scale was. She stepped onto it, then made a somewhat anxious face a few moments later.

“Is something wrong, Kirino?”

“Well... do you think I should put on some more weight?”

Ayase's face instantly grew beet-red. “W-what? You were thinking of getting bigger? Since when?”

Kirino dropped herself onto her bed, causing it to creak. She lay down, her belly bulging upwards, and preceded to gently rub it as her friend watched. “Well... it might sound weird, but I've been feeling like I'm not that fat recently. Don't get me wrong, I know that I'm still really huge, but I've just felt unsatisfied. You remember what it was like when you were gaining, right?”

“Yes... after the first twenty pounds or so, I really started to love it. I liked the felling of getting softer all the time and I really started wondering how I could have enjoyed my body when it was so small. Though I think a lot of that was just because I was gaining with you. I'm not so sure I could have done it without your help.”

“Well, that's the thing. I'm starting to lose that womanly feeling now that I'm big. In my mind, I feel like I'm getting smaller again. I think I might need to start gaining again to recapture it.”

Ayase walked over to the bed and sat next to her friend. The bed was visibly straining from the burden of supporting nearly 500 pounds of fat flesh. “I hope you  aren't wondering if I'll disapprove. You know that I got fat just so we would be more alike. Just look at me.” She poked her finger into her gut, letting it sink deep inside. “I certainly have nothing against your body or mine. If you want to get even bigger, go ahead. I think... well,” she smiled and blushed. “I think you might look even better looking than you do now.”

Kirino sat up, smiling mischievously. “Oh, ho! So Ayase, the model, moral citizen, has a thing for fat chicks?”

“I- what? No, I...”

Her bigger friend bounced up from the bed and faced her still-seated girl. “Is that why you love having these private sessions with me? So you can watch my fat body?” She grabbed a roll of fat and shook it, causing her belly to enter a spasm of motion. “I bet you love looking at my belly all the time. I don't blame you, it's hard to miss with how big it is. Look how much it spills over my pants now, too.” She grabbed her lower belly and lifted it slightly. “It's so huge that none of my clothes can hold it in. Or maybe...” she turned around, her mountainous rear just a foot from Ayase's face, “Maybe you prefer checking out this ass every time you come over?” She spanked it, causing Ayase to make a slight noise of surprise. “I think it's my best part, myself. I love how I can feel it bounce as I walk and how it spreads out and overwhelms all the tiny chairs I sit on. So which is it, Ayase? Do you prefer my fat gut or this big booty?”

Ayase could only stammer incoherently, her eyes wide. “The... I... it's...”

Kirino started laughing. “Oh god, Ayase, you look so shocked! I was just joking, but maybe you do have a thing for me!” She bent over, laughing even harder. Ayase could only try to recover her bearing and pout.

“That was mean, Kirino!” She stood up and faced her friend. “The way you're always grabbing my fat, I could say the same thing to you!”

Kirino wiped her eyes, still smiling. “Oh, Ayase! What can I say, I like how soft your body is just as much as my own.” She wrapped her arms around as much of her wide friend as she could, giving her a hug. Their breasts and bellies squished against each other, creating an incredibly soft sensation for both of them. “Thanks for the laugh. I guess I don't have anything to worry about if I put on some more weight.”

“Well,” said Ayase, immensely enjoying the feeling of Kirino's lush and squishy flesh, “I can't have you getting too much bigger than me, or else I'd feel insecure and puny when we're together. If you gain, I'll try and keep up with you.”

“Hah!” Kirino ended the hug. “I'd like to see you try! You're still twenty pounds lighter than me, small fry! And I just know you wish you could have a body like mine. Although...”

Ayase squealed again as her friend grabbed onto her gigantic chest. Kirino laughed uproariously as she groped them. “Man, I can only hope I get boobs like these. You gotta share your secret with me!”

The black-haired girl could only pant in resistance, her senses overwhelmed by both pain and pleasure.

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

The sun was setting on Kyousuke and Ruri's second date in Akihabara. They had once more had a wonderful time together, as evident by the smiles on their faces as they walked hand in hand down the sidewalk. The outing had other similarities with the first as well, as Kyousuke had scrounged together the money to keep his insatiable date sated with all manner of food.

“And from the way her belly is bulging underneath that sundress, I'd say I've kept her full.” Kyousuke kept sneaking subtle glances as Ruri's fattened body every chance he got. All of her soft, pale flesh, from her pillowy legs to her boisterous behind, to her bouncing belly, was extremely alluring to him. He couldn't help but imagine how it would feel to touch her body, how his hands would maneuver all of her heavy yet fluffy fat, how-

“Senpai?” Ruri was looking at him. “Are you ill? Your face is growing rather red.”

“Er...” Kyousuke frantically looked around, searching for something to distract from his embarrassment. His eyes fell on a shop with cosplay displays in the window across the street. “Hey, Ruri, how about I buy you an outfit from that store over there? I bet they have the new models from Meruru's newest movie there.”

Ruri looked taken aback. “That is a very substantial offer... the prices on such outfits are often quite high. That and the lack of larger sizes,” she put a hand on her gut, “are why I merely use such stores as references to design my own outfits.”

“I don't mind at all. You're worth the money.”

Ruri blushed furiously and opened her mouth to protest. Kyou raised his hand, stopping all further argument.

“Now now, let me do this for you. I'd genuinely like to. We can at least see if they have something in a bigger size for you.” With his hand firmly holding onto hers, they made their way into the store.

Not surprisingly, the shop mainly had outfits for girls of a very petite size. While Ruri could have fit into all of them before her gain, with her body swollen to more than twice it's original girth, only a miracle could have made them work now. After twenty minutes of searching, to no avail, Ruri grabbed hold of part of her date's shirt.

“Kyousuke, it's perfectly alright if we can't find anything. It's not at all shocking that I can't fit into any of these, after all. And just looking at them is nice.”

“Hmm... Well, it doesn't look like we're gonna-” It was then that he noticed a box near the sales register with a picture of a skimpy blue outfit from the recent Meruru movie. The box's text all happened to be in English, oddly enough. And while Kyousuke couldn't speak English to save his life, he was at least savvy enough to know that multiple X's in front of an L meant that the outfit was pretty big. He walked to the clerk at the register.

“Excuse me, but would you mind telling me what outfit that is in that box there?” He pointed in the mysterious container's direction.

“Oh, that? Accidental shipment. They sent us a batch of the newest Meruru outfits, but half of them turned out to be a model meant for America by mistake. Apparently the movie was a big hit amongst certain types over there, and the outfits are in demand. Of course, all but the smallest of the shipments are too big for most of our customers, so we're in a bit of a bind. Why, were you interested?”

“Well...” Kyousuke glanced at Ruri, who was busy observing another costume. He surreptitiously pointed at her and whispered to the clerk. “You think that one of the outfits might be able to fit her?”

The clerk smiled. “Well, I'm not used to dealing with such generously proportioned customers, I'm afraid. But I can at least give you 50% off on this outfit, since we’re stuck with them anyway.”

That was still a rather steep price, but the mental image of Ruri in the midriff-exposing, short-skirted costume caused Kyousuke to whip out his wallet.

“Sold!”


A short time later, the two of them were alone in Kyousuke's room. The young man had insisted on bringing Ruri inside his house to show her the “surprise” he had bought. Since she hadn't seen him purchase the outfit, and it was within a bag, she was left guessing at what sort of costume he had got for her.

“I'm rather shocked that you found something of adequate size. I wasn't aware there were many cosplayers of comparable girth as me.”

“Well, the clerk said it was made for Americans. I guess that means you're becoming a citizen of the world nowadays, aren't you?”

Ruri could only make a tired-looking face at Kyousuke's joke. “Senpai, did you just bring me here to comment on the international ramifications of my size, or are you going to show me the costume?”

He cleared his throat, recovering from his poor joke. “Ahem. Anyway, here you go.” He pulled the skimpy outfit out of the bag. “Ta-da!”

Upon seeing the outfit, Ruri could only laugh. “Goodness, senpai, your really are eager to get a glimpse of my body, aren't you? Considering how conservative I dress, you surely realize this would be a marked change for me if I wore this?”

He could only give a guilty smile. “Well, I figured you might enjoy something that gives you a chance to show off how beautiful you are. Since it's just me, too, there's no one you have to worry about.”

She took the grab from him. “Considering what a pervert you are, I would say that you're the biggest person I should fear seeing me with a deal of flesh exposed... Well, I suppose I shall have to take the risk. Leave the room for a few moments. I will call you back in when I am done changing.”

The young man left, clearly eager to see his girlfriend's abundant body in such a revealing outfit. She quickly removed her sundress, leaving her only in her bra and panties. She prodded her generous gut and watched it bounce.

"I just can't seem to stop my outwards growth, can I? Not that I would want to." She grabbed and shook a thick roll of fat, causing her whole belly to shake.

"In fact, I wonder whether me or Kyousuke enjoys my big body more." She put on the blue top, which fit perfectly over her moderate chest, leaving her overfed gut exposed. She then began the harder task of pulling the blue skirt of the outfit up, struggling to fit it over her bulbous rear. She was even forced to suck in her belly in order to fit it around herself.

Her face grew red as she tried not to breathe while she attempted to get the skirt fit. "I guess... the outfit wasn't as large.... as senpai thought." A split second after getting it into place, she gasped for air, allowing her fat middle to spread out, bulging over the bottom half of the outfit in a flood of corpulence.

Before inviting her admiring boyfriend back into the room, Ruri observed herself in the cosplay as best as she could. "I look shockingly good in this...". she thought. And indeed she did. From her fat belly in front to her mountainous booty in the back, Ruri was the image of a bloated and overfed Asiatic goddess.

She squeezed her lower belly roll, containing a desire to moan as her fingers sank in to the soft flesh. "I'm such a greedy pervert, she thought. As much as Kyousuke. I just want to eat and eat all the time and keep getting bigger. I'm sick of being tiny and thin and watching what I eat. I want to eat as much as I want all the time and not care at all about what anyone thinks of me."

She continued to fondle and squeeze her rolls of belly fat. "All I want to do is eat all day and grow huge and fat. I want to be so big that no one could ever think I was once a petite and shy girl. I'll be the queen of Kyousuke's world and have him cater to my every desire. I want to dwarf him in size and intimidate him with my girth, making him nothing but my-”

A knock on the door broke her out of her thoughts. “Ruri? Are you okay?” She quickly let go of her corpulence and tried to contain her shaking voice. “Y-yes, I'm quite alright. You can come in now.”

Kyousuke opened the door and set his eyes on all of the exposed flesh of his hefty girlfriend. "Oh wow, I guess Americans aren't as fat as I thought. She can barely cram herself into that." Just as the pressure of the top produced a large amount of cleavage, so did her tight skirt cause her belly to bulge out extra far.

Ruri let out a laugh at the lustful look in her boyfriend's eyes. “I take it you believe you made a wise investment on this outfit?”

He silently nodded.

“Well, just wait until you see all of it in action.” She turned around, showing her bulging booty off. The skirt left a hint of each fat cheek exposed, and she decided to put the massive amount of junk in her trunk to work to entertain Kyousuke. She stepped away from him, giving her hips a large swing, causing the huge mass to sway dangerously from side to side. After a few sways of her wide lower half, she stopped.

"I hope this isn't too lewd... But I've got to convince him to go a step farther in our relationship." Slowly and hesitatingly, she began to lean forward, causing her rump to bulge further outwards, the skirt slowly inching up her butt, exposing more and more flesh, until-

RIP!

Ruri froze in shock as she felt the skirt tumble to the ground, torn completely in the back. She placed her hands on her big ass, hoping to feel the skirt's fabric. Instead, all she could feel was the softness of her stupendous behind and her woefully inadequate panties.

She turned to face Kyousuke again, her eyes beginning to water from the humiliation of having ripped her clothing in front of her crush. “I... I...”

In a moment, she was in Kyousuke's embrace, his strong arms wrapped around her and pressing into her squishy sides.

“Don't cry, Ruri. It was my fault for getting too small of an outfit for you. You didn't do anything wrong.”

She sniffed. “I k-know you like me being big, but now I'm s-starting to get so huge I'm ruining the clothes you b-bought for me. And it was so hard for you to f-find an outfit that fit and it cost you so much money and I just went and-”

He put a finger to her lips.

“You think I mind? This is probably the best purchase I ever made. I got to see my voluptuous girlfriend in a outfit that showed off all of her best parts, and then got treated to a show of having her killer body completely destroy it. Love, you were just too big and sexy for it.”

She looked up at him. “S-so you aren't mad?”

“Heh. Not at all. In fact, watching that happened made me pretty excited.”

He lowered his arms, slowly feeling every inch of her fleshy back. Slowly, he maneuvered over her two gigantic cheeks, each hand covering a laughably small portion of her expansive rear. He gave it a gentle squeeze, savoring the feeling of incredible softness.

“Oh... Kyousuke...” Ruri lessened her grip on her boyfriend as his hands ran over her body.

“Your ass is amazing, you know that? Every time I see you from behind, I'm always hypnotized by it. How it's so wide, how it pushes out so far, how it sways when you walk. It's all I can do to keep from grabbing it whenever I look at it.”

He gave it a light pat, feeling as his hands sank into each fluffy cheek, causing Ruri to let out a slight pant. From there, he ran his hands over her lovehandles, giving them a slight squeeze as he moved onto her vast gut.

“And this belly?” He gave it a few light slaps, watching it quake. “I can't think of a better thing for a cute girl like you to have on her. Something this soft and plushy isn't something you should be ashamed of. I love it, after all.”

He fondled the huge ball of soft fat, grabbing underneath it, slightly lifting it, and letting it drop to see the ripple effects it sent through her body. He massaged it, feeling as much of its surface as he could, and gave occasional squeezes to it.

“I don't think you get just how much your body excites me. When I see your belly poking out of shirts after you've stuffed yourself full of food, or when I see your shorts barely managing to cover up your big butt, I can barely control myself.”

He slowly let go of her fleshy middle and moved up to her chest, his hands barely an inch away from her breasts.

“Can I show you how much I love you?”

She slowly nodded.

He gently pulled the blue top off, leaving her standing in only her bra and panties. With nearly all of her fat body on display, she looked down, embarrassed. She quickly looked up again, however, as Kyousuke began to remove his shirt and pants. In a moment, both of them had only their underwear on.

“Let me demonstrate how incredible your body is.”

[Time Skip]
“I like big butts and I cannot lie.”

Ruri hummed a few terrible Engrish verses of the song as she rubbed her huge booty against Kyousuke's crotch. Weighing in at over 400 pounds, Ruri had passed “big” long ago. After a year of constant gorging, her wish to be fat enough to fulfill all of Kyousuke's desires had come true. Nearly every part of her body had blown up, though she had developed a pear-shaped form due to her relatively small breasts compared to her huge hips and plush middle. Her face, too, remained only slightly affected- her cheeks had softened, giving her a bit more of a cherubic look, while the rest remained as sharp and unyielding as the young tsundere's demeanor had always been. But wearing the skimpy cloths she had become accustomed to- she loved to parade her big belly and butt around for her boyfriend- most of her growth was openly visible. Her middle, so fat that it had become two large rolls of adipose, bulged outwards and over her shorts. Anytime she walked, her lower belly jiggled and shook, sending vibrations throughout her whole body that made her excited. Yet while her poor shorts were overwhelmed in front by her gut, they were equally in trouble on the other side. Slight rips were becoming visible due to Ruri's ever-growing hips and ass. Over a third of each butt cheek was visible due to the sheer inability of the fabric to cover such copious amounts of booty.

A colossus of soft and jiggling flesh, Ruri's girth made her downright intimidating. Though she may have been short, the fact that she was now about as wide as she was tall made someone think twice about mocking her weight. This was aided by the fact that growing to over four times her original size had had a significant affect on her personality. While she had always had a venomous tongue, her once shy nature had given way to one of selfishness and a need for immediate gratification. Constantly hungry, if Ruri didn't have something to stuff her face with at every moment of the day, she quickly grew terrifyingly angry. And the dark-haired girl took advantage of her size. She knew she was big, she knew she was heavy, and she knew that she could use her mass to really ruin someone's day.

She was, in fact, doing that right now. Her sex drive had grown along with her form, and with Kyousuke the only guy she knew who loved fat chicks, Ruri needed him to constantly pleasure her. Yet even though he was a typically horny teenage boy, Ruri's insatiable desire for sex often left him exhausted. He had already fucked her three times today- this morning when he woke up due to the shock of her placing her huge frame on top of him, that afternoon, when she had barged into his room, stripped naked, and leaped onto him, and an hour later, when she forced him to give her oral sex. He didn't especially mind all the intercourse, though. He did indeed love fat chicks, and Ruri's willingness to mold her body to fit his preferences pleased him. He loved to see her jiggle and shake all over while he pounded her, her huge tits wobbling, her belly shimmying, and her giant ass quaking with every thrust. But he was getting awfully sore. Ruri's sadistic desires for dominance in the bedroom had left him with numerous bruises. He had to admit that he loved to feel all 400 pounds of her lying on top of him, but feeling it so constantly was having a major effect on his body. And as she shook her fat and juicy ass in front of him, he could just tell she was getting ready to do it again.

“Ruri... are you sure you want to have sex again? We've already done it three times today, and I'm getting tired...”

“Tired, senpai?” Ruri quit her booty dance and stood straight. “You weren't tired earlier today when I was sitting on your face. Or when you were grabbing my belly as you fucked me from behind. And your dick certainly doesn't seem to be tired.”

“It was true,” Kyousuke thought. His cock was rock-hard at the moment. A prime example of the mind-body dichotomy, his member simply couldn't get enough of Ruri's plump body.

“I don't think you truly appreciate what I've done for you, my love.” Ruri smiled as she talked in a sinister tone. “Thanks to you, I've completely ruined my figure. Don't you remember when I was tiny and shy? Most people thought I was beautiful then. If I had been confident enough, I probably could have as many guys as I wanted. But I didn't think that way back then- I only wanted you. Maybe I was a fool for wanting an idiot and pervert like you, but you were the only guy I thought I had a chance with... even now, you're one of the hottest guys I know. While I've stuffed myself every day, you've kept that sexy, toned body that I love so much. But it's your fault that I'm the way I am today. YOU'RE the one who loves fat chicks, after all. When I realized you would never be satisfied with me as a little twig, I willingly allowed myself to grow this huge. Every bite of unhealthy, fattening food that I stuffed down my throat, every night that I went to bed with a bloated gut, every pound that appeared on my frame is YOUR fault.

“Of course, that's not to say I didn't learn to love it. After I put on a few dozen pounds, I began to find myself much more sexy than before. Look at my belly, senpai.” Ruri lifted up her shirt, which was so small that it barely covered her navel to begin with. “Goodness, I think it's the biggest its ever been. Feel it, senpai.”

“Ruri, I don't think-”

“I told you to feel it, senpai.”

Kyousuke did what he was told. He reached out and grabbed as much as he could of his lover's soft middle.

“See how it bulges over my pants, Kyousuke? You know that that part's softest, make sure you rub that. And my love handles, too, look how plump they are. Go ahead and pat them. I know how much you love to watch this big gut jiggle.”

He gave it a firm pat and watched a visible wave of motion travel though her adipose. Getting a bit excited, he firmly rubbed it, causing it to shake even more.

“Tell me how big I am, Kyousuke. I want to hear it from you.”

“You're so huge, Ruri... I can't believe you used to be so tiny. I remember when we started dating and I could lift you in my arms.”

“Mmm... Why don't you try it now, love?”

The boy, willing to humor his gigantic girlfriend, wrapped both his arms around her belly. Though his arms sunk into her flesh, he still couldn't manage to link them together. With all his strength, he attempted to lift her. His face turned red as he strained to do the impossible. Ruri giggled at his struggles.

“Don't overdo yourself, senpai. After all, if you did managed to lift me, I'm sure I'd crush you when you let go. In fact...” Ruri shifted her weight and bumped Kyousuke with her massive hips, sending him stumbling back. He fell on top of his bed.

“Don't resist, Kyousuke. I know you love this. And I don't have the time to waste listening to your moaning- I haven't eaten in twenty minutes. I'm getting hungry again.”

She dropped the full weight of her ass onto her boyfriend's body. Her mountainous rear, over 100 inches in diameter, spread out over his crotch and lower body. She purred as she heard him gasp for air.

“What's the matter? Am I too much woman for you? I should hope that a strong man like you isn't overwhelmed by a few extra pounds. Well... maybe more than a few. I really can't stop eating at this size, you know. I need to consume thousands of calories just to keep this sexy body at its current size. But that's not enough for me. I'm not through growing. I've barely put on three hundred pounds, after all. You wanted a fat girlfriend, didn't you? The last thing I'd want to do is disappoint you, my love. I'm going to eat every scrap of food I can get my hands on until I'm so big that I won't be able to  fit through the front door anymore. And then I'll just sit around, all day, eating, sleeping, watching anime, and having you fuck me. That sounds pretty great, doesn't it? Tell me you want that future for us.” She shifted her bulk slightly, giving him air. He gasped for breath.

“Better tell her what she wants to hear, or else she'll use her weight to really hurt me,” the boy thought.“Of... of course that's what I want. I want you to be the biggest girl in the world! I want to be able to lie on you, sink into your flesh, and use you as a bed! I want you to lie on top of me and completely smother me with your fat body! I want to spend every yen of my money buying food for you so you can keep growing forever!”

“Oh, Kyousuke!” Ruri felt herself growing wet between her legs. She heaved herself up, and began ripping off her apparel. “Get your clothes off! I want to see every last inch of your body!” Kyousuke obeyed, her, stripping naked as fast as he could, though he was distracted by watching his sexy, blubbery girlfriend. Watching her attempt to pull her enormous panties off got his blood heated, and as she released her bra, her breasts bulging forwards, his dick stiffened even more. She noticed this development and grinned. Falling on him once more, she immediately began licking his member. As he moaned in pleasure, she laughed.

“Don't get too excited, senpai. Remember when we did this for the first time and you came in ten seconds?” Kyousuke opened his eyes and stuttered with embarrassment as Ruri chuckled. “Well... at least you last longer now. I'm not sure what I'd do if you came before I did.” Her eyes narrowed, and Kyousuke gulped nervously. “In fact, if I wanted to, I bet I could have my way with you even if you didn't want it. God knows it's not tough for me to get you hard. I just have to jiggle my belly or shake my huge ass and you pop up like a soldier. And at my size, I doubt you could resist me. I'd just have to squish you up against a wall with my gut or squash you under all of my luscious fat. You'd give up thoughts of resistance really fast.” Kyousuke wasn't quite sure that was true- he was still stronger than she was- but he knew it still wasn't a good idea to piss off a girl that outweighed you more than three times over and whose ass was big enough to crush a car. She squirmed her massive form forwards and lied on top of her boyfriend. His body was enveloped by her soft and fleshy form as she maneuvered his dick into her pussy.

“Now fuck me, Kyousuke! I want to feel you inside of me!” Her aroused and intimidated lover was only too happy to oblige. He thrust as hard as he could, raising his massive girlfriend slightly upwards. She began to shout as his manhood stimulated her. “Ah! Oh! You're... so big, senpai... You're so strong to be able to... handle all of me.” She was already panting, her bulging body causing her to tire just from the exertions of intercourse. But she was horny as fuck, and she wasn't going to let a few hundred pounds of soft flesh prevent her from fucking her lover. In fact, her tiredness was getting her more aroused. It reminded her of just how big she had become, just how much gorging she had accomplished to be able to grow this large. She became aware of how much space her figure took up as she felt ripples of motion travel throughout her whole body. “Tell me... how fat.... I am, senpai... Tell me you... want me even... FATTER!”

“You're... so fat, love!” Kyousuke himself was panting from both the energy he was putting out to furiously fuck his girlfriend as due to the lack of air he was getting from being squished by her. “Your belly is... the biggest I've ever seen on a girl! I love how it... bulges over your shorts and how I can... sink my hand so deep into it that I can't see my fingers... Your tits are so big that they... they can't even be contained by your bra any more!... And your ass is the biggest... fattest... booty in all of Japan!”

“OH KYOUSUKE!” Ruri was furiously panting as she neared climax. Drool dripped from her mouth as she salivated at the delicious feeling she was about to experience. “MAKE ME BIGGER! MAKE ME FATTER! I WANT TO BE HUGE! I WANT TO BE THE FATTEST GIRL IN THE WORLD! I WANT... I WANT... AH!”

The two lovers, one large, one small, orgasmed at the same time. Ruri screamed as she felt Kyousuke's hot cum course through her inner regions, and Kyousuke moaned as Ruri collapsed on top of him. They gripped each other tightly as they gasped for breath, recovering from their intense pleasure.

“I still can barely breathe... but at least this more than makes up for it,” Kyousuke thought as he hugged Ruri's colossal body, embracing her excessive softness. After a few minutes, they had both recovered enough to slow down their breathing. Ruri smiled as she rested her soft cheek against Kyousuke's.

“Senpai... that was wonderful. You're so good at this.”

“Only because you turn me on so much, Ruri.”

“Heh. I do, that's very true” The smile slipped from her face and was replaced with a look of sincerity. “But I really am so lucky to have you. I did get fat for you, but still, I know how bossy and demanding I've become recently.” As he opened his mouth to respond, she covered it. “Shh. Don't deny it, love. I know that getting so huge has really affected my personality. I've gotten so greedy and short-tempered. But that doesn't mean I love you any less than I did at the start of our relationship. It's just that being this fat makes it tough to summon up the effort to do even simple tasks. And I'm so hungry all the time, which makes me easily irritable.” Kyousuke grunted beneath her hand, trying to speak. “No love, I'm not finished yet. I just want you to know that no matter how big I get, or how rude I act you sometimes... I'm still your little Kuroneko. Well, go ahead, senpai. Tell me if I've upset you in any way recently.” The boy gasped for breath as she removed her arm.

“That's great Ruri, and I love you, but... do you think you could get off of me? I haven't been able to breathe right for fifteen minutes, and I can barely feel my legs.” Ruri blinked in shock.

“What!? That's all you have to say to me after I pour my heart out to you?” Her full cheeks turned red, betraying her intense embarrassment. “You... you idiot! I ought to sit on you for the next hour!”

“N-no, please, love! Anything but that! I might die!” Kyousuke was at the verge of panicking, making Ruri inwardly laugh. He was so cute when he was afraid.

“Fine, then.” She squirmed as she pulled herself off of him, heaving herself upwards, her full and naked ass exposed to his view. “If you want to make up for that, you need to go to the kitchen and bring back enough food to completely fill me up. I haven't eaten in over half an hour, and I'm practically wasting away here!” She slapped her double-rolled belly for emphasis. “You wouldn't want your fat, sexy girlfriend to lose any weight, would you?” He shook his head. “Well then, what are you waiting for? Go get me food, NOW!” She stomped her foot, causing the whole room to quake, as if the house itself was afraid of her mighty girth. Kyousuke jumped out of bed and dashed from the room. Ruri laughed as she saw his manhood bounce as he ran, naked, to the kitchen. Living the fat life sure was fun.
