“Senpai! Let’s go out for ramen!”

Shinichi Sakurai turned around, swivelling his neck down to see the distinctive silver hair of his annoying pint-sized kouhai, craning her head up at him with her trademark opportunistic grin. If only she were more average, he had long lamented, so that he might be able to pretend that he hadn’t seen her and go about his day, but it was impossible to not recognise Uzaki when you saw. With her below-average height making her tantalisingly tiny even by the standards of the average Japanese woman, all of the height that she had been denied had gone straight to her chest, a head of height turning into two head-sized breasts flaunted with the two words on her favourite t-shirt. It was, of course, irrelevant, as even if Uzaki had been the plainest, most unremarkable girl in Japan, her personality made her stick out even more than her body did.

Once, he might aggressively fought off her attempts to, in her words, fix his reclusive attitude, but he was long past the point of avoiding any of her attempts to hang out with him. He could fight it, but no matter what he said or thought he would either inevitably be dragged along with her, or she would drag herself along with him. In fact, he had already been dragged along on this quite a few times… maybe a few too many times recently, in fact.

“Again? We just went out for it yesterday! And the day before that!” Sakurai pointed out, glaring at her.

“Yeah, but I’ve been on a real ramen kick lately! You can never have too much!” Uzaki brushed him off. “You can be boring and order something else when we get there if you really can’t handle it.”

“I thought you were the type to call me boring if I had the same thing over and over.” Sakurai said in an accusing voice, Uzaki playing dumb with a cute, innocent look on her face that only irritated him more. “Anyway, that’s not the problem, the problem is that all you ever seem to

“I’m a growing girl.”



“You’re in college! The only thing that’ll grow is your waistline!”

Uzaki shook her head smugly. “Maybe you have to worry about watching your weight, Senpai, but I’ve got a good metabolism

Sakurai narrowed his eyes and sized her up. Uzaki always had a big appetite, but it seemed that she was exceeding her standards  That t-shirt of hers was looking awfully tight today… but then again, when didn’t it?

“Fine, but

“Don’t worry, I won’t have to!”



“And you’re paying for your own meal!”



“What!? And you call yourself a gentleman!?”

The two continued to bicker all the way to the restaurant, but the truth in Sakurai’s words would hit harder than Uzaki ever could have imagined…

–

“Seenpaaaaiiii! Let’s go out for ramen!”

Whatever reaction Uzaki had been expecting when she pounced him on the way home, Sakurai’s look was scathing enough to give even her pause

“How many times in the last month do you think you’ve said that?” he said, running a hand through his spiky hair. It seemed like all Uzaki wanted to do lately was eat, and it was wearing thin on his patience and his wallet. Uzaki paused, looking like she was seriously trying to count each time.

“Umm…”

“You don’t need to answer that!  It’s too much!”



“Fine, fine!” Uzaki pouted, crossing her arms. What was his deal, anyway? Guys were supposed to want to go out for dinner with girls, and all he ever did was complain! This was why he didn’t have a girlfriend. “We’ll get fast food today, I was in the mood for a burger anyway!”



“That’s not the problem, the problem is your appetite!” Sakurai nearly shouted.

“What about it?”



“Remember how I said if you kept eating like this you’d get fat?” Sakurai reminded her, crossing his arms right back at her.

“And?” Uzaki said impatiently, starting to get hungry. “What about it?”

“You tell me!”

Uzaki looked down into the overstretched letters on her shirt. Okay, so maybe her clothes felt a little tight, but it couldn’t be that bad, right? Right?

“I don’t see anything out of the ordinary.” Uzaki said, taking the coward’s way out. It was technically correct, as there was no way she could see her body below her enormous chest. Sakurai sighed, pulled out his phone, and took a photo of the slightly flustered Uzaki, who couldn’t help but pose slightly, managing to put a smug smirk on her face just in time for it to flash.

“What, picking up photography as a hobby now? Is this gonna be your new wallpaper?”  Uzaki began to get into her usual routine, then went pale when he turned the screen’s phone around. While she had been able to deny it in the mirror and even in the shower, the photograph cut through all of her delusions and put the real her on display, and the real her was getting kind of fat. Her t-shirt was straining at the chest to contain her extra breast-flesh, and unbeknownst to her, had been pulled up so far that her pudgy pink belly had been hanging out, and although one might have accused all of her fat of going to her chest before she started overeating, in reality once she started seriously packing on the pounds this was no longer the case. Uzaki had a distinct pot belly that pushed out past the waistline of her skirt, a slight muffin top spilling over the waist of the denim material. Her thighs were clearly chunkier, filling out the available space under her skirt and rubbing against each other in the photo, and it was clear if they got much bigger her skirt was going to start looking like more of a miniskirt. Even her stockings had sprung a few tears in places, cementing the fact that she had sailed past chubby into straight up overweight. Even her cute face was starting to turn flabby at the cheeks, not enough to give her a second chin, but certainly threatening to.

“Okay, so maybe I overdid it a little.” Uzaki mumbled bashfully.

“You think!?” Sakurai was exasperated, to say the least. “What did you expect? You’ve been eating enough for three of us!”



“But it seemed like such a good idea at the time!” Uzaki whined, jumping up to try to gaze pleadingly into Sakurai’s eyes for mercy, him having now gained and undisputable advantage in a relationship where she was supposed to hold all of the cards. She came up to his neck, giving Sakurai pause. There was something else that was a little off about her, and it wasn’t just her weight.

“Hey, Uzaki…” Sakurai said cautiously. “Is it just me or are you bigger than usual?”



“You were just yelling at me about that!” She complained, Sakurai shaking his head.

“No, not that, I mean taller!” He corrected himself.

“...huh.” Uzaki looked down, then up at him, then back down again. Uzaki had always been so tiny she barely came up to his chest, and now she found herself closer to staring at his collar than the middle of his pecs.

“Hey, you’re right! I totally forgot that this happens.” Uzaki said, sounding more curious than surprised.

“What do you mean ‘this’?” He asked.

“Oh, did I never tell you? When I put on weight I kinda get taller too. It’s a family thing.”

“What!?” Sakurai exclaimed. “That’s crazy!”

“It’s not that weird.” Uzaki shrugged.



“It totally is though!” Sakurai had always thought that his kouhai was pretty weird, but this one really took the cake. He brought up his phone, tapping away at it.

“I got a little fat back in middle school after I broke my leg this one time, and I was taller than Mom by the time it finally healed. Of course, I lost it after that, but still.” Uzaki explained while Sakurai furiously looked it up, his eyes widening at all of the results he got.

“Rare condition… Affects one in every… What the hell, this is totally a real thing!”

“See? Told you.” Uzaki took pride in every small victory. “Senpaaaaiii, don’t tell me you didn’t even know that!”



“How was I supposed to know!?” He decided to let that one go rather than take her bait and fight her on it. “This is even more reason to start thinking about a diet, or you’re going to outgrow all of your clothes in two ways!”

“What, senpai, are you scared I’m gonna get taller than you?” Smugness filled Uzaki’s face, her personality easily seizing upon anything

“You haven’t gotten that much taller, squirt.” Sakurai planted his hand on her head as if to push down and force her back towards the ground where she belonged. “You’d have to get seriously huge if you wanted to catch up with me, and I’m not that tall.”

Uzaki paused for a moment, looking deep in thought. She seemed to be seriously contemplating something, and slowly but surely, her face morphed into a grin that only got wider until it was a broad, domineering sneer.

“Okay senpai, you win, I’m gonna start a new diet right now.” Uzaki said, skipping ahead of him and giving him a good look at her ass, chubby enough to start making an indent through her skirt.

“You mean it, right?” Sakurai said cautiously. He really didn’t like the look on her face right now. It was one that told him that she was up to no good, even moreso than usual. Still, weight was something that girls took seriously, right? Surely he didn’t have anything to worry about, and she was just being weird about it as usual.

“Of course I do! I’m gonna completely change my eating habits.” She said suspiciously enthusiastically. This just made him more worried, knowing that Uzaki was the type to go down kicking and screaming if asked to not indulge herself. But maybe he was thinking too harshly of her. Maybe in a month or so she’d be back to the Uzaki he knew…

—

“Senpaaaaiiiii, we’re out of snacks!”



Uzaki kicked her legs petulantly without looking away from the game she was playing on Sakurai’s TV, surrounded by empty wrappers and packets from her laid-down position on the floor of Sakurai’s apartment, although she took up quite a bit more of said floorspace than usual. Clad in shorts and her favourite t-shirt, the very act of kicking sent her burgeoning thigh-flesh wobbling with each motion, and it didn’t help that those legs were quite a bit longer than they used to be. Uzaki’s position on the hardwood floor was cushioned by a sagging gut as big as any pillow he owned, not to mention her now literally watermelon-sized breasts assuring she’d have to work to get her chin to hit the floor. As for said chin, Sakurai suspected it’d be quite comfortable on the floor by itself, with the prominent second chin she had sprouted in the weeks since her supposed declaration of diet.

Uzaki had gone on a diet alright, Sakurai thought as he stared down at his overweight houseguest, a high-calorie diet that would have made a bodybuilder trying to double his body mass blush. There was no muscle being built here, only more tender, squishy flesh, disqualifying her from even a sumo wrestler’s diet. Sakurai had expected her to return to her usual slender self after their little chat, but the next time he had seen her a few days later her broad grin had been widened by extremely chubby cheeks and the beginnings of a second chin, and her appetite and weight had only increased more rapidly since. Every time he saw her she seemed to be snacking on something, and every time they ate out she seemed to have demolished enough meals for a large family in the type it took for him to get through one serving. Bowls stacked high, fast food serving trays smothered in burger wrappers, chicken buckets, and extra-large cups of fries. Uzaki had turned into an eating machine, and it wasn’t long before it became obvious that it was no accident.



Sakurai had initially turned a blind eye to her eating antics, initially believing that she was gorging herself before she was forced to diet no matter what, then that she was slipping on her diet when she was around him, and letting her spiral out of control would teach her a lesson. As the weeks passed, he was finally forced to admit that there had been no diet at all, and there was no karmic retribution, no I-told-you-so, no consequences of her own poor decisions he could smugly rub in her face as she got bigger, as it was quite clear that she wanted to get bigger. For what reason… well, he could hazard a guess.

“And? What do you want me to do about it?” He asked, staring disdainfully down at the gluttonous pig who had cleaned out what was meant to last at least a couple of weeks in half a night.

“Go get some more, obviously.” She said.

“Do it yourself.” He said, hoping to at least see her face of despair at his barren larders, but she hardly twitched.

“Can’t you see I’m busy?” She said, her eyes glued to the screen in the midst of combat. “You were the one who said you didn’t want to play together right now…”



She was unable to hide the disappointment in her voice in the second half, although Sakurai in his poor mood interpreted it as her missing out on an opportunity to crush him in some game.

“Well even if I wanted to, I can’t! We’re all out!” He crossed his arms, Uzaki pausing in horror.

“What!? Who’s fault is that?”



“Your fault!”



“No, it’s yours for not buying more!”



“Are you trying to bankrupt me or something!?”

“What a terrible host! You’re lucky you never have any guests over besides me!”



“Then stop coming over uninvited!”



“No way! I don’t have this game at home.”



“Then I’ll lend it to you if you’ll get out!”



“And have to start over? No way!”



The two reached a standstill, Uzaki eventually pausing and turning over, sprawled out without dignity upon his apartment floor. She had stubbornly stuck to her favourite blue shirt even though it had long since been outgrown, leaving her entire midriff uncovered and her jiggly belly hanging out, her love handles happily spilling over the sides of her shorts, her gut usually sagging out enough to hide the fact that she’d had to undo the button of her shorts just to make them fit her now almost twice as wide hips, but in her current position Sakurai tried to ignore the fact that he could almost just barely get a hint of her panties. The sleeves were pushed to their limits, pressed tight against her flabby biceps, and the sugoi dekai letters were finding that perhaps she was now too dekai even for it, stretched out and almost warped.

“Well, I’m hungry, so let’s make dinner. I’ll even cook it for you!” Uzaki proposed, but Sakurai shook his head even at that.

“I don’t have enough ingredients for that either.” He said, Uzaki looking dismayed.

“Oh come on, Senpai, now you aren’t taking care of yourself either? I swear, what would you do without me around?”



“It’s not that, idiot! I was going to go to the convenience store right before you showed up!”

“Ah.” Uzaki looked slightly guilty. “Well, since you’re going anyway, can you pick me up a few things? There’s this brand of potato chips I really like that they make in party size, and-”



“No way. If you want to eat, you go.” Sakurai decided to put his foot down, Uzaki looking wounded.

“You are just the worst host, Senpai!” She complained. “I cook, you do the shopping, that’s a fair deal isn’t it?”



“The reason I don’t have any ingredients to cook with is because you came over last night and ate them all!” Sakurai pointed out, Uzaki faltering.

“T-then, fine! I know a fair way to settle this!” Uzaki said desperately, her stomach already growling in protest. “We’ll play a game! Whoever loses has to do the shopping!”

“No way, you’re not weaselling out of this one.” Sakurai stood firm.

“Do you wanna starve or something?” Uzaki cried.

“I can go the rest of the night without eating no problem. But you probably won’t last another hour.” He said smugly, grinning down at the pouting Uzaki. She tried to give him puppy dog eyes, but he turned away from her, figuring he’d won until suddenly, something incredibly soft pressed into him from behind. A comforting pillow against his lower back, and two squishy mounds on his back, Sakurai turning red as two smooth, soft arms wrapped around him.

“Hey, Senpaaai…” Uzaki said from behind, pushing several hundred pounds of weight into him. “Come on, you’re not just gonna let a delicate little girl go out there on her own, are you?”



“What’s delicate about you now!?” He gasped, breaking away before he started enjoying that softness a little too much. Uzaki giggled at his reaction, and he whipped around, ready to shout at his tiny kouhai, only for his words to die in his throat as he found himself staring almost face to face with Uzaki, who had put on over a foot of height since her rapid gain. She smirked at him, almost five feet and nine inches tall in comparison with his five feet and eleven inches. It was clear that this had been the goal of her obsessive overeating: to even the height gap between them.

“Oh, I see why you don’t want me to eat tonight.” Uzaki said, grinning devilishly at his flustered expression. “You’re worried that you’re going to be the shorty soon!”

“Like hell I am, you whale! You’re gonna have to lose that weight eventually!” He almost jumped away as she put a hand on her head and nearly moved her hand forward into his nose, demonstrating her new measurements.

“Says who?” Uzaki said, grabbing her belly and jiggling it herself. “It’s not that bad once you get used to it. I didn’t see you complaining until now…”



“Don’t expect me to solve your problems for you!” He almost stuttered out.

“Don’t you mean your problem?” She said smugly, standing up on her toes and leaning forward.. “Right now I don’t see a single downside to-”

Uzaki was interrupted by a loud tearing sound, freezing and going pale in the face. Sakurai circled around her, frozen in place, and let out an exasperated sigh Uzaki’s strained shorts had been pushed a little too far, and had split down the middle, unable to contain her massive ass any longer. Her white panties were on full display, but this time she was the only one embarrassed by letting him see them.

“Maybe I should go after all.” Sakurai said pityingly, scratching his chin. “You might get stopped by a policeman for public indecency at this rate…”



“I-it’s not that bad!” Uzaki said, but when she tried to reach around to cover it, her poor sleeves finally gave up the ghost and her right arm split at the seams, the left busting open a hole and threatening to follow its partner if she flexed any harder. Uzaki began to sweat, Sakurai gaining the upper hand once again.

“You should spend less on food and more on new clothes.” He commented, Uzaki blushing furiously.

“S-shut up! I was gonna go shopping this weekend!” She protested, and how true this was was unclear. She looked at Sakurai pleadingly. “Senpai, lend me something to wear! Forget shopping, I don’t know how I’m gonna get home like this!”

“Will my clothes even fit you now?” Sakurai asked, eyeing her waistline cautiously.

“We’re practically the same height now, right? I’m sure it’ll fit.” Uzaki said.

“I wasn’t talking about your height…”



“Come on, Senpai! Just because you don’t have a girlfriend doesn’t mean you can let an innocent young girl run around your apartment in her underwear!” For shame!”

“Fine, I’ll find something!” He gave in, going to his wardrobe and digging out his loosest sweatpants and a baggy top. Averting his gaze as Uzaki stripped out of the remains of her clothes, the fat girl slipped into his pants, the elastic waistline thankfully expanding enough to safely contain her, even if it dug into her fat a little.

“Hey Senpai, remember when this thing looked huge on me? If you ask politely I might let you borrow my clothes too.” She giggled, pulling on his shirt that would, had she gotten taller without getting fatter as well, would have fit her quite naturally. As she was in reality though, it could just barely contain the girth of both her chest and her belly, and it was clear that it was straining to just contain the former alone. With enough effort she managed to pull it down and tuck it into the waistline of her pants thanks to the soft material.

“Hey, Senpai, this is kinda comfy. Can I keep ‘em?” She smiled, Sakurai not dignifying her with an answer. It wouldn’t be until tomorrow that he would find out that she had stretched them beyond repair, the pants not having a hope of fitting his slim waist afterwards and he would steadfastly refuse to let him ruin any of his clothes afterwards.

“Well, anyway, you’d better get going, Senpai. I’m clearly in no state to be going out and…” Uzaki said, only to find Sakurai blocking her path to the TV, a controller in hand.

“You said we’d have to decide who goes this way, right?” He said, having even swapped the game while she was changing.

“Hey, no fair, you’re good at that one!” Uzaki whined, pointing at him accusingly. “I was gonna pick one that you suck at!”



“Don’t be so honest about it, moron!”

Ten minutes later, Uzaki was gnashing her teeth in frustrating, her battle in their racing game doomed from the start.

“You cheated! I didn’t know that shortcut existed!” Uzaki argued, nearly throwing the controller down in anger before the results screen.

“I won fair and square.” He said smugly, kicking back and stretching his legs.”You’ve better get moving, it’s getting late.”

Uzaki slowly climbed to her feet, but instead of slinking off in defeat, Sakurai soon found himself staring up at the underside of her belly, his shirt having come untucked and leaving him peering up at the creamy, sagging gut-flesh that she wore so proudly. Before he could say anything, Uzaki suddenly planted her fat ass down on his lap, Sakurai gasping as the air was driven out of him. Heavy! Uzaki was heavy! Too heavy!

“What the hell do you think you’re doing!?” He groaned, pinned to the ground. His hands sunk into her flabby thighs, trying to wrestle her off him, but she clung to the ground and stabilised herself, rubbing her pillowy ass into him.

“Punishing you for fighting dirty against a girl.” Uzaki said. “You’ll never get a girlfriend if you don’t know when to let them win!”

“I don’t want to hear anything about fighting fair from you!” Sakurai almost shouted, seizing her love handles and trying to drag her off to no avail. Uzaki blushed a little at his handling of her, but her amusement at pinning him down overpowered it. “Now get off of me!”



“What, Senpai, you can’t even lift a girl off of you? And you call yourself a man?” She taunted, moving herself up a little onto his chest as he was pushed flat by her weight. “What are you even doing in that gym all day? Do you just say you’re going so you can show off?”



“Shut up! Just because I work out doesn’t mean I’m a powerlifter!” Sakurai struggled, trying to find purchase on her body to get her off of him.

“H-hey! Watch where you’re touching!” Uzaki yelped.

“Touching what? I can’t see a thing back here!”



“Ah, no! Senpai! Not there!” She wailed as she began to lose balance trying to get his hands off of her, letting out a girly squeal as Sakurai finally managed to shove her to one side, Uzaki capsizing with a mighty thump as Sakurai squirmed out from under her, scrambling to wobbly feet and retreating to the other side of the room.

“Aha, take that! Now hurry up and…” Sakurai’s triumphant cry trailed off as he looked down at Uzaki with her hands crossed defensively over her chest. Sakurai turned red and turned away, both feeling that they might have gone a little too far.

“You know what, I was thinking I wanted to go for a walk anyway. I could use some fresh air.” He said loudly, heading towards the door. “You want anything in particular while I’m there!”

Uzaki perked up a little, tugging at the hem of her overstretched shirt.



“Can you pick me up a cake while you’re-”



“Don’t push your luck.”
