"Hey, Rikka. Did you get a boyfriend?"

Namiko stood over Rikka, who was reclining in her seat. The blunt question was said casually, but it was obvious that she was eager for a response. Rikka paused for a moment, as if deciding whether or not to keep that information secret, then sat upright.

"I did." Rikka said simply, getting an immediate reaction from the two that was stronger than the matter-of-fact way she had said it.

"She said it." Hase added, sounding impressed, the masked girl sitting next to them as the three formed their usual lunch break group.

"I knew it." Declared Namiko, the short-haired girl sounding jealous already. "I could feel it, the aura of a girl with a boyfriend. You were holding out on us dateless girls."

"It's not like I was hiding it." Rikka said lazily, hiding the fact that she was slightly proud.

"Well it's not like you were telling us either." Namiko objected. "Ah, to think our Rikka overtook us already..."

"So, who is it?" Hase asked, more laid back than Namiko but clearly no less eager to hear it.

"Haruto from next year." Rikka said, leaning forward to rest her chest on her desk, hiding her self-satisfied look at her friends' datelessness.

"Seriously?" Namiko was surprised. "Our Rikka is into chubby older guys? My image of you is like, changing."

"Is there something wrong with that?" Rikka sighed. It's not like she had expected to be dating him of all people either, but it had just worked out that way.

"No, it's just that I was sure it'd be... no, I guess he's taken right now." Namiko rose her hand to her chin, her eyes flickering to a certain red-haired boy at the back of their class, who was currently chatting with the ever-popular purple-haired Akane, which was a serious step up for a nobody like him. Namiko had been sure that he had the hots for Rikka and that the two had been building up to something, but it seemed that Akane had swooped in and proven too much to resist. You snooze you lose, she decided, for the both of them.

 "So, why'd you two start going out?" Hase asked, ready for all of the juicy details.

 "He asked me out, so I said yes." Rikka said.

 "That's it?" Namiko asked incredulously.

 "That's it."

 "So our Rikka is that kind of girl..." Namiko sighed melodramatically. "As your parent, I don't know if I can approve..."

 "Don't act like my mom."

 "How could you date your senpai without asking permission from your own mother first, Rikka?" Namiko grinned. "Looks like you're working on becoming a matching couple already by the look of these."

 Namiko placed a hand on one of Rikka's extremely plump thighs, Rikka blushing slightly as Namiko's slender hand took up much less of her naturally healthy thighs than usual. Rikka's thighs had been rapidly plumpening over the last few weeks until finally they began to spill over the sides of her seat alongside her clearly engorged hips, causing her to have to lengthen her skirt to cover her bigger ass, while her usual long jacket now only managed to cover the top half off her butt. Her jacket managed to conceal her slightly softer midsection, but it was impossible to not notice that Rikka was starting to get on the chubby side.

 "I guess I have to share these now." Namiko sighed, sitting down and placing her head in Rikka's pillowy thighs. "Maybe I should thank him for making them even comfier."

 "He's here." Hase said suddenly.

 "Huh? Who's-" Namiko didn't get to finish her sentence before she was unceremoniously lifted off of Rikka's thighs, jolting upright as she watched as Rikka stood up and went to meet somebody at the entrance of the classroom. The two watched silently from a distance as she talked briefly with an overweight boy who was slightly shorter than her, able to tell from her body language that she was pleased from their short interaction. He handed her a box and the two parted, Rikka returning to her desk with what turned out to be a large bento box.

 "He's kinda cuter than I expected." Hase said appreciatively as Rikka popped open the bento, stuffed with rice and tasty ingredients.

 "He makes you lunch!?" Namiko said incredulously as Rikka dug in, looking slightly smug at Namiko's envious gaze. "I'm never gonna find a guy who'll make me bento..."

 --

 "You didn't have to come to my classroom, senpai." Rikka said to her boyfriend, walking alongside the rounded youth after school after she had parted with her friends. "I told you I was going to come by, didn't I?"

 "Sorry, I couldn't help myself." Haruto said sheepishly, but obviously showed little regret. "But it's not like they don't know we're dating, right? Besides, I thought you'd be hungry."

 "Well NOW they know." Rikka sighed, leaving out the details of their conversation prior to his appearance. "So, where do you want to go today?"

 "Hmm, how about that family restaurant from last week?" Haruto suggested.

 "Again? Well, if that's what you want. After all, you're paying." Rikka seemed unsurprised, guessing his ulterior motives besides simply wanting somewhere to spend time with his girlfriend. As he predicted, she showed almost no resistance to the idea, and the two held hands as they travelled to their inexpensive but comfortable get-together spot. It would have been a surprising sight to see the two, as chubby was being generous to the plainly overweight young man. Haruto had a large gut pushing out his shirt and a wide face with a rounded second chin, although his features weren't unattractive, giving him a certain plush cuteness as Rikka's friends had noted. He was slightly shorter than Rikka and wider despite her feminine pear shape, although if the two dated for much longer it was clear that Rikka would overtake him. Otherwise plain with short, neatly cut hair, it would have come as a surprise to most to see that he had landed such an attractive girlfriend, but he was determined to make the two of them a natural fit before long.

 The two arrived at their destination and sat down, ordering drinks before picking out what they wanted from the American-style menu. Rikka made a fairly modest order, but Haruto's order to the waitress seemed to never end.

 "We'll get this, and that, and that too." Haruto completed, pointing at the menu as he seemingly ordered most of what was on it. The waitress simply smiled and nodded as she jotted down the immense order.

 "That had better not be all for me." Rikka said warily as she watched his self-satisfied smile upon completion, sipping from her soda as she gulped down empty calories as a prelude for what was to come.

 "You looked hungry." He smiled innocently, and Rikka crossed my arms.

 "You're seriously doing this again, senpai? My friends are noticing that I'm starting to get fat." She said, and although she looked displeased, Haruto knew for a fact that her resistance was merely for show. He had made sure of it.

 "Is there anything wrong with that?" He smiled, and Rikka simply sat back quietly without the usual rejection one might have expected of her.

 "I would have dated a skinnier guy if I'd known I was expected to eat like my boyfriend." She said finally, and the two chatted idly while they waited for their food to arrive. When it did, the table was flooded with burgers, bowls of fries, steaks, and other juicy fat-filled dishes that were conspicuously placed on Rikka's end of the table.

 "You'd better help me with this." Rikka said as she stared down the mountain of food before her, gulping as she thought of the immediate effects on her fat thighs.

 "Of course, just eat as much as you feel like." He said sweetly with his own greasy burger in hand, Rikka licking her lips in anticipation as she raised her own.

 "I'm having just a little bit, not as much as last time." Rikka promised, taking an experimental bite. Her eyes lit up the moment she did, and he knew she was hooked. She began to wolf down the burger quickly but cleanly, and within moments was starting on the fries, emptying the bowl with a steady pace as she took occasional sips from her drink to wash it down. Then she started on her second burger, then her third, and it was clear by the gluttonous look in her eye that there was no stopping her. Haruto sat back happily eating his burger at a measured pace as Rikka devoured enough food for ten or more, eating like a woman possessed as she only stopped briefly to complain that he had ordered too much food before digging back into it.

 Rikka's belly began to grow visibly distended as she reached her natural limit then kept going unabated, having half left by the time she normally would have complained she was full, only for her to keep going and test the capacity of her stomach as she paused to clean her hands on her napkin before lifting her knife and fork and stuffing her hamburg steak into her greedy mouth. Finally, after quite some time, the table was bare, and Rikka groaned and leaned back in her seat, resting her hands on her bloated belly, noticeably rounded and sticking out as if she was a few months pregnant.

”Ohhhh… senpai… A little help please? I don’t think I can stand up." Rikka puffed as she rubbed her taut belly, Haruto deciding that he was happy with the shape of her belly for today. Full wasn't even close to describing how she felt, and she let out an appreciative sigh as Haruto reached under the table and began to run a hand down her thickened thigh, clearly enjoying it before frowning slightly.

 "H-hey Senpai… not here." She blushed as his hand reached her butt, gently pushing it away. He was starting to seriously lean into it, and it was no longer a subtle motion."Maybe back at your place?”

 He took her hand and helped her up, paying the bill as Rikka shuffled awkwardly out of the building, adjusting to the weight of the food settled within her.

 "Did you enjoy yourself?" He asked as the sun began to finish setting, and Rikka paused for a second before leaning over and giving him what she intended to be a quick kiss on the lips, only for it to linger much longer as he hugged her, her stuffed belly pressing against his fat midsection. Her stomach churned and groaned slightly, preferring to not be stressed at the moment.

 "Maybe." She said, hiding her smile and turning away. She looked back to see Haruto checking his phone, pouting slightly.

 "Hey, senpai, pay attention to me, not that." She said cutely as he hurried to hide what he was looking at, the thing that had made his beautiful yet rapidly bloating girlfriend possible...

--

“Ugh, I’m exhausted. I don’t think I can move.” Rikka groaned as she fell back onto Haruto’s bed, the two arriving at his thankfully not too far away home. Rikka fumbled to undo her jacket’s bottom buttons, then her blouse’s, letting her distended belly pop out slightly. “God, I’m huge.”

“You’re not that big yet.” Haruto said, leaning over and giving her another quick kiss, which she seemed to quite enjoy.

“I’m gonna be a total fatass at this rate.” Rikka complained, letting him run his hand down her thigh as he sat down next to her. “My ass IS fat after all these dates, after all.”

“You have the best big butt in town. The best legs, too.” Haruto complimented her, Rikka unsure how much of a compliment she should take that as given how rapidly she was gaining. “I still can’t believe I’m dating such a beautiful girl.”

“Your beautiful girlfriend’s gonna get fat, senpai.” Rikka smirked. “You sure you’re okay with that?”



“What do you think?” He asked her, returning the smile as his hands went higher on her body.

“I think you’re totally into it, senpai.” She accused playfully as he began to rub her sensitive belly, gasping slightly as his chubby hands sunk into it. “The other guys are gonna stop being jealous if I get any heavier, though.”



“Who cares what they think?” He laughed, and she pulled herself upright with a grunt, placing her own hand on his plush belly, pushing through the fabric and in.

“It’s gonna be a while before I catch up to you, anyway.” She said, although not as slowly as she might have hoped, he personally knew. “I can’t imagine what it must be like carrying this around.”

“Maybe you’ll find out?” He said as she continued to knead his belly, finding his softness strangely appealing. To be honest, she had surprised herself by saying yes when he suddenly asked her out, deciding to go with it on a whim because the boy she had thought she liked seemed to be more interested in another girl. Haruto had proven to be a good boyfriend, eager to spend lots of time with her and she had found herself strangely drawn to him, like the more time they spent the more he grew on her. As a result, she didn’t find it unusual at all that she was back at his house, on his bed, trading gropes with him after a massive meal.

“Forget it! I’m gonna burn this off soon. Enjoy it while it lasts.” She shut him down with a resolution that he knew for a fact she was going to fail spectacularly. His hands stopped short of her chest, and she looked down at her petite breasts with a frown.

“If I’m gonna get fat, these had better get bigger.” She declared, looking at her distinctly pear-shaped figure, where little of the fat she had accumulated had gone higher than her waist. “I can’t stand my boyfriend having bigger boobs than me.”

“Come on, I’m not that big.” He said slightly defensively, and Rikka responded by unbuttoning his shirt, letting his flabby gut hang out as two plump moobs hung from his chest. She grabbed them abruptly, squeezing them a bit as if to say that two could play at the feeling up game, enjoying his blush at the sensation.

“Well, are they bigger?” He asked eventually, and Rikka turned up her nose.

“Who knows?” She said with just a hint of jealousy.

“It’s not fair that you’re the only one who gets to take something off.” He declared, unbuttoning his skirt, Rikka blushing but standing up letting him tug it off.

“This is definitely bigger than mine.” He decided as he grabbed her butt, squeezing one of the fat cheeks. Rikka promptly sat back down again with a blush, leaning against his shoulder as the two pulled into a gentle cuddle, Rikka enjoying his softness and wondering how long it’d be until she herself was soft enough to return it, if she kept gaining weight at the rate she was. As it was, her stuffed, distended belly squished against his gut, giving the embrace mutual softness enough. The two were enjoying the back and forth, but there was only so far they could go at this stage in their relationship. Rikka seemed to be as tired as she said it was, as it wasn’t long before she began to drift off into a food-induced coma.

Haruto quietly left her on the bed to take her nap, her gut hanging out and her skirt on the floor, pulling out his phone once he was out of potential eyeshot should she wake up. He looked down at his phone, which had a most unusual sight on it: There was a portrait of Rikka on it reflecting her current appearance, accompanied by a number of text boxes that could only be described as the interface of a traditional dating sim, supplying various statistics on her such as her height, age, three sizes, and weight. There was also a box adorned with hearts that read Affection towards Haruto: 34%. If this was thirty-four percent after a little over a month and a half of dating, then Haruto couldn’t wait to see eighty or even a hundred percent. This curious dating sim of Rikka’s life had a few more boxes listing her interests, likes, dislikes, and compulsions, and was obviously designed for user input. He had of course taken full advantage of this, starting with the most important box: the men she had a crush on. Originally Hibiki Yuuta had been the one name in the box, but he had added himself above him, and quickly taken priority. Her voracious appetite was also his doing, as he had added a compulsion that once she started eating food in front of him, she couldn’t stop, and he was pleased to see that she had a burgeoning natural glutton trait off in another box as a result. Soon, he wouldn’t need that compulsion to have her reach his ideal weight.

It wasn’t all perfect, of course. That affection level had dipped slightly on occasion when he had done something to upset her early on, and he had been warned that he still had to conquer her route if he wanted to truly win her over. He was just able to easily stack the deck in his favour by editing her as he pleased. But how had he gained such a strange, reality-altering power? He thought back to the one who had given it to him: Shinjo Akane…

--

“Come on, where is it?.” Haruto panted as he reached his window-side desk, the sound of the sports clubs in the distance muffled through the classroom window. He had completely forgotten his phone and only realised when he was halfway home, and had to run all the way back worrying it had fallen out of his bag at some point and since gotten trampled. With his overweight body running was obviously not his strong suit, but he had surprising stamina that wasn’t totally cancelled out by weighing roughly two hundred and fifty pounds.

“Not here. Not here. Not here!”

He groaned in despair as his phone didn’t seem to be on his desk, on the floor, or anywhere in the classroom in general. He ended up slumped against the window, wondering if there was any chance of finding his poor phone or if he’d just have to accept working a part time job flipping burgers until he could afford another one. He could ask his friends if they had seen it… but that would require he had a phone in the first place!  He looked out of the window in depression, watching the girls track team make loops around the yard. He had been good at running in elementary school, hadn’t he? Before his love of eating outpaced his love of exercise. Despite his appearance it wasn’t like he was unpopular or friendless, merely lacking notability and presence. Average, like most high schoolers of his age who didn’t have some quirk that made them stand out. On the plus side it meant he didn’t have any bullies who might have decided to mess with him, on the other hand it meant that his chances of getting a girlfriend were next to nil, and this wounded his soul.

“I wish I had a girlfriend…” He mumbled, slumping into his seat.

“Want one?”

Haruto jerked in surprise at the sudden feminine voice next to his ear, the girl giggling as he nearly toppled over, just barely managing to grab his desk and stop his chair from falling at the last moment. His head snapped over to see a certain purple-haired girl laughing at his misfortune, and he blushed as he stabilised himself and stood up.

“W-what is it?” He asked, completely embarrassed that she had heard him. How had she gotten so close without him noticing?

“Didn’t you hear me the first time? I said, do you want a girlfriend? Don’t make me repeat myself.” The busty purple-haired girl said playfully, although making it clear that she meant it. Hang on, wasn’t this Shinjo Akane? The Shinjo Akane? The most popular, most universally liked girl in the school? Everybody knew her, and he was no exception. But what was she doing in this empty classroom talking to him about girlfriends?

Haruto paused for a moment, and made the obvious if foolish conclusion.

“You mean me and you-”

“Not me, stupid.” Akane seemed to be expecting this, and gracefully turned away as she backed off from her chubby senpai. “I’ve already got a date. Jealous, aren’t you?”

“A little.” He admitted. This whole situation had started awkwardly and was getting worse. Of course a girl like her would already have a boyfriend! “But, uh, why come to me to brag about it?”



“I told you not to make me repeat myself. Don’t you know it’s rude to not listen to people?” Akane smirked, then reached into her loose jacket and pulled out a familiar device. “Looking for this?”

“Oh, thanks for picking it up!” His relief broke through the awkward atmosphere, but she held it out of reach.

“So, do you want a girlfriend or not?” Akane stressed this and made it clear that it would be the last time she asked.

“Well… I do. I think most guys would.” Haruto said, trying to assert himself a little. “But what does that have to do with anything? I appreciate you coming and finding me, but-”

“You like Takarada Rikka, don’t you?” She said suddenly, and Haruto felt knocked off-balance.

“Takarada? W-we’re not even in the same year.” He began to perspire, and not from having to run back to school.

“Like anybody cares about that. Especially boys.” Akane began to play with the phone, dangling it from her fingertips and getting dangerously close to dropping it. “But you have a crush on her, right? I get it, Rikka’s super cute.”

She sounded almost proud of herself for some reason.

“Maybe.” Haruto reluctantly admitted. He’d seen her a few times, and had found himself immediately attracted to the beautiful girl and her aloof attitude. Had she been a little older and he a little lighter and more charismatic, perhaps he might have had the bravery to make a move on her, but as it was, it was merely a simple, casual crush based on attraction. Plenty of guys had something like that, didn’t they?

“You wanna try dating her then?” Akane seemed very fixated on this, but he couldn’t for the life of him see where she was going.

“It’s not that easy.”

“You’d be surprised.” Akane grinned. “Even a fatty like you could get her, with my help.”

“You’re playing matchmaker now?” Haruto exclaimed. “Does that mean, uh, that she, you know, likes me, and you came here to tell me that?”



“Of course not, stupid!” Akane let out a harsh laugh. “She probably doesn’t even know you exist! But that doesn’t matter. Why don’t you just go ask her out?”



“Are you crazy?” Haruto was getting a little tired of this teasing act. He got it, she was here to try to embarrass himself. Well it was working, but he wouldn’t call that difficult. “I’m not doing that in front of everybody!”

“Good thing you don’t need to! She’s just downstairs right now, you know.” Akane smirked. “And she’s alone! Isn’t that the perfect romantic opportunity, senpai?”



“What, really? But no way. I don’t want girls spreading rumours about me.” Haruto shuddered at the idea.

“Well you’re not getting this back until you ask her out.” Akane stashed the phone back in her jacket’s interior chest pocket. “Guess you’ll just have to go for it, senpai!”



“Seriously?” Haruto said, his jaw falling. Were all popular girls this mean? Attempts to bargain with Akane failed, and so he quickly found himself peeking around a corner where Rikka was searching her own classroom for something.

“She’s looking for this.” Akane giggled, pulling out a second phone that left Haruto dumbfounded. Does she just go around stealing phones like that all the time? How did she even manage it twice? “Anyway, good luck, senpai!”

Haruto was kicked through the doorway despite his hushed protests, and was soon standing awkwardly before Rikka, who looked surprised to see him.

“Uh… Haruto-senpai, isn’t it?” Rikka broke the awkward silence.

“You remember?” He was surprised.

“Yeah, you helped me with that thing, right?” Rikka alluded to a particular task the two had been roped into that had been their only substantial interaction. “What is it? I’m kind of looking for something…”

Haruto glanced back at the concealed Akane. Guess it was do or die time.

“Takarada!” He barked her last name awkwardly. “Will you go out with me!?”

Rikka’s eyes widened at his blurted confession, and time seemed to stand still as images of his school life dying flashed through Haruto’s mind. Finally, Rikka spoke.

“Sure.”

“Seriously?” Haruto couldn’t believe what he was hearing.

“Seriously.”



Haruto had a lot of questions. How and why were the most important ones with how impromptu it was. Had Akane prepped her for this or something?

“Um… I’m glad, but why?” His curiosity got the better of him.

“Well, this is the first time a guy has asked me like this.” Rikka admitted with a blush. “It’s worth a try, right?”

“Uh, yeah, yeah! Of course! Should we do something now, or…?”

“I’m still kind of busy…” Rikka said, the scene becoming awkward again when Akane burst into the room with a look of glee on her face.

“Ah, Rikka, there you are! I was searching all over the place for you!” Akane lied. “Looking for this?”

“Did you hear all that?” Rikka asked, Akane playing innocent.

“Hear what?” Akane smiled. “You should be grateful by the way, I came all the way back from my date with Yuuta for you.”



“Never mind.” Rikka hurried over to take the phone. “Senpai, about that… thing… Meet me tomorrow after school, okay?”

Rikka rushed out, leaving the two alone.

“See?” Akane said smugly.

“I can’t believe it.” Haruto said. “Thanks, Shinjo! I seriously thought you were just messing with me.”



“You should be. You’re doing me a favour, after all.”



“A favour?” Haruto asked.

“I said I was dating, right? I had just one little problem:” Akane began to explain. “Even though we’re dating, Yuuta keeps looking at Rikka. Isn’t that just awful of him? I mean, we’re dating, right? Isn’t that being, like, unfaithful?”



Akane’s tone was getting downright menacing.

“Maybe you’re just overthinking it.” Haruto suggested, and Akane glared at him.

“So I thought, wouldn’t it be better if Rikka had a boyfriend of her own?” Akane ignored him. “That’d fix everything, right?”

“Okay, but… why me?”

“You were the guy with the biggest crush on her.” Akane explained mysteriously. “And I know you’ll do the best job with my help.”

“How did you know that?”

“I know a lot of things.” Akane smiled. “Hey, senpai, you like dating sims, right? There’s no way a guy like you doesn’t.”



She was right, but Haruto didn’t want to admit it, particularly when it was such a bizarre and abrupt question. She held up his phone, the screen lit up as she finally handed it to him.

“Why don’t you try out the Rikka route?” She suggested, and he looked down at his phone to see what was, absurdly enough, what appeared to be an actual dating sim with a portrait of Rikka on it. It was animated and everything, and he gave an odd look at Akane.

“Did you install something weird on my phone? How’d you even do that?” This was getting seriously weird.

“I’m sure you’ll have lots of fun with it. Make sure you use it before your big date!” Akane instructed him, and swiftly left, ignoring his protests. Haruto wasn’t quite sure how to mentally catch up with this whole thing. First he got his phone stolen by the most popular girl in the school, then he landed a dream date, and now she appeared to have installed something weird on his phone. How’d she guess his password in the first place? It was a lot to take in, so he merely waited until he was sure nobody was around, pumped his first in the air in celebration, and then promptly went home.

In the comfort of his own home, Haruto took a closer look at the so-called dating sim Akane had given him. But if it were a dating sim it were an incredibly limited one, being more of a summary of Rikka than a real game that he could actually play. Still, assuming that all of it was accurate, it was a comprehensive way to know what Rikka liked and didn’t like ahead of time. He cruised around the UI, taking mental notes. She liked romance movies, which made potential dates easy. Once he got to her weight it also mentioned that she had a slightly lower than average appetite, which made him look down at his own plumpness self-consciously. Sure he had landed the date, but would she really stick with a guy like her?

His finger drifted onto the box by accident, revealing a drop-down with various options. That was strange, given the dating sim theme, to be able to directly change things. Had Akane taken some sort of dating sim maker and set these values and descriptions manually? He jokingly set her appetite to large, figuring that she wouldn’t judge him if she were also a big eater. It wasn’t like anything he messed with here mattered, right? The whole thing was skeevy to begin with, so he may as well not take it too seriously. He reached her list of things she liked, being unsurprised that they had little intersection when it came to hobbies. He decided to add “mecha” to her list of likes, getting a laugh out of the idea of a fashionable girl like her being secretly fixated on something like that.

There was one interestingly empty box: compulsions. It seemed purely there for him to edit, and so after some wishful thinking, he did: namely that in front of him, she wouldn’t hold back on eating. The idea of a girl stuffing herself in front of him was certainly a guilty pleasure, and he decided that if he felt bad about modifying her profile he’d just fix it later. The options he had added were written in red text, making it easy to tell which ones were his and which were supposedly natural.

Next came the box that listed her potential lovers, or rather, those she had a romantic interest in. This was probably the most dating sim-like part of the program, really. The box only had two names, himself obviously included. Haruto checked the other name in the box: Hibiki Yuuta. Wasn’t that that redheaded kid he had seen a few times? Actually, hadn’t he seen him and Akane together recently? He tapped on the name out of curiosity, which brought up a portrait of the young man with its own stat screen, although less comprehensive and interactive than Rikka’s. He tapped on Yuuta’s relationship box, which listed Rikka and Akane on it, each with their own affection stat. Interestingly but perhaps unsurprisingly based on what Akane had said, while it did have a low percentage for Rikka, presumably enough to indicate a crush, Akane’s was currently notably higher. They were supposedly dating, after all. For Akane to be insecure over this paltry amount… well, his more popular friends had warned him that girls could be clingy like that.

Satisfied for now, Haruto went to bed, not thinking much of the whole thing. He had a date to worry about, after all. Whether it went badly or not, he could at least say that at some point in his high school life he did, in fact, have a girlfriend, and that was enough of a victory for him.

--

The first date was, to Haruto’s relief, a success. The two met up slightly awkwardly without much of a plan, and had ended up wandering through a mall before getting something to eat, simply enjoying each other’s company as they tried to figure out exactly what couples were supposed to do. However, there were several coincidences that Haruto simply couldn’t overlook. The first was when they were wandering through the mall, and Rikka had stopped to stare entranced at a lineup of mecha figures in a hobby store’s window, eventually pulling herself away with embarrassment and reluctantly admitting that although she didn’t watch anime, they were pretty cool. The second was their meal, where Haruto had, in his nervousness, accidentally over-ordered as he tried to change his choice several times and the waitress had chosen to interpret them as that he wanted all of them.

 To his amazement, when the table arrived stacked with food and he had offered to split it with Rikka, the girl whose only plump part was her thighs ate the lion’s share of it like it was nothing, Haruto ending up with only the scraps as he offered his portions with how enthusiastically she was eating. In the end she only seemed to gain a sense of self-awareness once she was done, apologising and saying that she usually ate a lot less, and must have been unusually hungry that day. He was lightning quick to dismiss her apology and say that it was more than okay, but what had intended to be an excuse to get to know each other had ended up being a gorging session on her part. The craziest part was that although her stomach was slightly pushing out of her top by the end of it, when the two parted he overheard her wondering to herself what her mother was making for dinner. There was no way such a slender girl ate like that all of the time and stayed thin! Something had to be up! But it couldn’t be… right?

He couldn’t help but add a couple more specific things to her profile. That she enjoyed keeping her hair in pigtails, that she would wear blue on a date. To his shock, she had shown up the next day with her hair done up in pigtails just as he had put on her profile, and wore a blue hoodie that she had bought right before their date. To top it off she displayed the same enormous appetite she had before when they went to a movie together, going through two boxes of jumbo popcorn before they were even halfway through the movie, starting with her own and taking his when she ran out. By that point Haruto was convinced that there was no coincidence, and the first time he got the chance, confronted Akane about it. Akane, mysterious as ever, simply laughed at him and seemed delighted that he had figured it out this quickly, and told him to make good use of it. As long as he kept Rikka romantically occupied, she said, she’d share her special gift with him. He had a million and one questions for Akane’s power, but Akane refused to answer and merely instructed him to shut up and not think about it too hard, and to merely thank her whenever things went his way.

And so, despite his natural curiosity, he did. What reason did he have to complain that he didn’t know the truth, when Akane’s slightly threatening manner made it clear that delving too deep might not end well for him? He quickly reverted the colour and hair choices, preferring her usual style and having merely used them as a test, and debated long and hard about what to add. Doesn’t mind fat, he eventually decided was important, still feeling insecure about his body despite the fact that he didn’t seem to be turning her off in the first place. The vagueness of his phrasing would come in handy down the road, but for now it was merely putting one of his fears about himself to rest. For the moment, he decided to let things play out as they were. Things seemed to be going well enough, with her affection slowly but steadily rising, and no sign of their relationship doing anything but growing closer. His friends were incredulous and jealous when they found out that he had a girlfriend, and his pride emboldened him to not make an attempt to hide it.

Eventually, after a month of dating, the inevitable happened. Rather, it had been happening, but became impossible to ignore: Rikka was putting on weight. Her clothes grew tighter, more inadequate, only serving to show off how much she gained with each passing day. Her plump thighs grew plumper, her ass rapidly growing in girth as her fat seemed to be concentrated in her waist, namely her thighs, her hips, and her increasingly huge ass. Haruto’s fascination with watching her stuff herself meant every date involved huge portions, and she seemed to have an equally huge appetite at home, going for seconds and thirds of anything she could get her hands on, although she apparently lacked her impulsive eating when he wasn’t around, just as the program had specified. With the way she was eating rapid weight gain was natural, and as Rikka plumped up, far from lamenting the loss of his petite girlfriend, Haruto began to think that she looked good with some extra meat on her bones.

Haruto might not have enjoyed being overweight in public, but in private, where he wouldn’t be judged, he didn’t mind being heavier, and had never felt that a fat woman was a negative. As a result, when his own girlfriend showed off her flabby thighs and pooching belly to him after he gave her a compulsion to show herself off to him while she was changing at a clothes store on one of their dates, he found that he couldn’t be happier. In fact, it’d be nice if they ended up as a matching couple once she inevitably hit his weight. While Rikka occasionally grumbled and complained about her weight gain, he could tell that it wasn’t seriously bothering him, and she had hidden a smile when he said that he didn’t mind it at all. Eventually he made it so that Rikka enjoyed being groped, and she quickly stopped complaining when he felt up her thighs, and even her ass when he felt he could get away with it.

Weeks turned into months, and Rikka’s weight gain began to snowball as the habits he had given her only intensified. Rikka was eating more than ever both under his guidance and without, and soon it began to show on more than just her waist as time passed . In addition to her becoming noticeably wider than him, her ass dominating her frame as her thighs individually became as thick and wide as her entire body had been, two enormous ass cheeks larger than any seat smaller than an armchair. Her pear-shaped fat distribution kept her gut flabby but relatively flat as opposed to his large, round bulge, but the sheer weight on her body caused her breasts to grow until she outpaced her boyfriend by a considerable amount, and her arms grew thicker and thicker until meat hung from them like a juicy bone, drooping biceps and chubby fingers that matched her boyfriend’s when they held hands. Her face began to grow noticeably rounded, but her body’s weight distribution spared her from an outright second chin, at least for now. Haruto was delighted with each passing pound she added to her frame, deciding that she only grew hotter the heavier she got.

Complaints about her physical education classes began to grow common when they spent time together, Rikka naturally performing abysmally and starting to outright avoid it when she could, which only caused her to get even fatter even faster. Despite catching up to Haruto’s weight and starting to overtake it in a few short months, the reaction to Rikka’s transformation was unusually lukewarm. Nobody had chided her about it, nor had she received any mocking from her classmates. Her friends teased her about it and squeezed her fatty folds, but nobody seemed to judge her about it, merely laughing that the two truly were a perfect fit for each other now. Not even her teachers or mother got on her case about it, her mother simply laughing that she was hitting her growth spurt. When he had questioned Akane about it she had implied that it was her doing, and he decided to simply accept his good fortune.

Akane herself seemed to be doing quite well. She had made similar progress with Yuuta, and cackled at how even if she hadn’t recruited Haruto’s help, there was no way he’d get distracted by another woman now. Haruto was less of a conversational partner and more somebody for Akane to brag at, which he was more than happy to be for what she had done for him. She had had a fit of laughter at what he had done to Rikka to shape her to his preferences, and decided that Rikka was cute no matter what weight she was at, and that it was a plus that Yuuta didn’t seem to be into fat girls on top of that. She had mentioned something vague at how she hadn’t had to work off any stress or anger lately and that things were very quiet as a result, which he didn’t understand at all, but sounded like a good thing to him.

--

“So, what now? Want me to head home?” Rikka asked, the sun having set on a date just over four months since they started dating. The two were holding hands as they walked, her sausage-like fingers interlocked with his as she wobbled and shook with each step. Rikka was now around three hundred and fifty pounds by his estimates, having overtaken years of weight gain in a mere few months. Even with her incredible eating habits, Haruto attributed the speed of her growth to the trait “puts on weight quickly” that he had added to her profile.

“Let’s go back to my place. I want to give you something special tonight.” He said, sounding determined as he prepared to take a large step in their relationship.

“More special than that all you can eat challenge? Which you lost, by the way. I should be the one asking you to give me something special.” Rikka smirked as she rubbed her full stomach. “It had better make up for my pervert boyfriend grabbing my ass again.”

Haruto rubbed it again, Rikka making a show of faux-indignation, but he knew she was hornier than ever, having made it so that being truly stuffed made her aroused. It wasn’t long before he had walked her home. He took a deep breath as he opened the door, and led her inside. He began to nervously unbutton his shirt, pulling it off as Rikka had by now predicted what was going to happen, and began to also slowly unbutton her overstrained top, her skirt hitting the ground, followed by her bra and panties. When Rikka turned to face him, her eyes were dragged downward as if magnetically, where it remained firmly fixed on his penis, which could be described as nothing less than enormous, putting porn stars to shame with its girth. He had always had nothing to compensate for, but it had mysteriously grown even larger lately, seemingly a gift from Akane, perhaps telling him to get on with it already and seal the deal. Rikka’s greedy expression was obvious, and he could practically feel her getting wet at the sight of it.

It wasn’t the first time he had seen her slightly sagging breasts bare, nor was it the first time she had seen his erect cock, as the two quickly became bare. She had joined him in his shower once, and he had gotten his first taste of his shaft rubbing against her ass in the cramped confines, but it had gone no further, and the two had avoided taking the final step in their intimacy several times. Today was the day, and both of them knew it. Haruto pushed her down onto the bed, the two making out as he fondled every part of her body he could get his hands on.

“It’s not fair that you get to be on top, senpai.” Rikka said, even though he knew she was a bottom. He was surprised that she was asserting herself in this situation, but he wasn’t complaining as the two exchanged positions.

“You’ve made me so fat, senpai.” Rikka said breathily, climbing over him. “I thought you were a real fatass, and now look at me. You need to understand just how heavy I am now.”

Rikka dropped her ass over his face, smothering him instantly.

“You like this, don’t you?” She teased, shifting slightly as she salivated at the sight of his erect cock. Just as he began to run out of breath she finally lifted it, turning herself around and carefully placing his stiff cock between her two ass cheeks, slowly lifting herself up and down as he began to pant with pleasure. It was a testament to just how big her ass was that even his huge cock couldn’t peak over it, and she enjoyed watching his expression as she rode his chest, pleasuring him between her two enormous pillows of fat as with each wobbling thump he grew closer and closer to the edge. There was a meaty slap of mutual fat, compounded by the fact that she was atop his fat gut, which got squashed and compressed by her weight as she lifted herself up and down until finally he grunted and came, splattering her ass with his cum. Rikka finally stopped, rolling off of him to lay by his side, her face flushed red with arousal and he was given relief from her wonderful weight.

“Have you had enough?” She asked with concern, but he simply picked himself back up, his cock quickly hardening again.

“I can keep going, for real this time.” He declared.

“Be gentle, okay?” Rikka asked softly, eager, but also nervous. It was her first time, and her treatment of Haruto had been from somebody who knew that she would be a passive enjoyer once he really got started, trusting all control to him. Although she had made a show of taking control, the idea of how how helpless she was about to be was exciting, and a show of her trust in him.

He turned Rikka onto her back as he spread her thighs, lined himself up, took a deep breath, and slowly pushed himself in as Rikka began to mewl, Haruto grabbing her fat belly and squeezing it, moving down to seize her muffin tops as he played with the fatness he had created. He squeezed her hips as he began to pound her, Rikka gasping with each mighty thrust as he slid in and out, his inexperience being made up for with passion.

“You’re so big, senpai!” Rikka moaned, and He felt his belly collide with hers once again, the two large enough that they couldn’t help but press their fat against each other. Rikka let out a high pitched feminine moan as he came with force, splattering the inside of her womb with enough to make her belly visibly round from sheer volume. That was Akane’s gift, he thought to himself as he pulled out, semen dripping from the totally overwhelmed Rikka splayed out on the bed. There was no way a condom could have contained that, and Rikka realised it.

“That was our first time and I think you’ve already gotten me pregnant, senpai.” Rikka panted, the two recovering side by side. She leaned over enough to turn her head and kiss him, smiling in the darkness of their room. She felt no fear at the idea, only a warm glow over what the future held for them. “You know, I always wanted to be a mom. I hope you’re ready to take responsibility, Haruto…”

--

“Ugh, exams suck.” Rikka complained, squashing herself into the tight restaurant booth, clearly not designed for a girl who weighed over five hundred pounds. Rikka’s hips and ass took up the space of the seat designed for three people and still threatened to spill over, her custom-tailored school uniform stretched to its breaking point. “But Mom says I still have to get good grades…”

“I can help you study if you want.” Haruto offered, much more easily fitting his own corpulence in than his girlfriend of ten months.

“No way, absolutely no way.” Rikka shut him down immediately, leaning forward and resting her elbow on the table and her chin on her hand, her gentle second chin squishing against her flabby palm. Even as she ballooned to twice her boyfriend’s weight, she had often bragged about how she still had less of a second chin than him.  “I’ll fail all of my exams with you around. Be more considerate of your girlfriend’s needs.”

“I promise I won’t get distracted.” He said.

“I’ll get distracted.” Rikka smiled knowingly. She placed her hands behind her head and leaned back, her arms now thick enough that her fat pressed against the fabric, even through her pale jacket, and her belly fat pushed gently against the edge of the table. “Aah, maybe I should just drop out. Then I can focus on taking care of the babies, and I won’t have to wait until we both graduate to get married.”

“Your mom said she’d take care of them while you’re at school, didn’t she?” Haruto asked, the reaction to Akane’s pregnancy being as breezy as her weight gain. “There’s no need to go that far.”

“I think she’s happier about them than I am.” Rikka’s face told the story of how excited her mother had gotten about them over the months, to the point that she’d had to be the calm and level-headed one about the fact that she was having two, possibly three babies and was about to be a teen mother. “You wouldn’t believe how eager she is to be a grandmother.”

“I wish my parents were so easy-going about it.” Haruto sighed, having received hours of lectures about how he had to shape up and be a responsible father and husband.

“Your mom’s nice though. Plus she’s a good cook.” Rikka said, having been with him when they broke the news. She could see where Haruto had gotten his weight from, as his mother was as fat as he was and didn’t seem to be surprised at all that he had inherited his father’s chubby-chasing attitude. The waitress finally arrived and the two ordered, Rikka noticing that his own order was even lighter than usual.

“You’ve been really hungry lately, right? It just means more for you…” He weakly defended himself, only for Rikka to shake her head vigorously.

“No way. It’s not fair if you don’t stay fat, senpai.” Rikka insisted. “Just look at what you’ve done to me, you’ve turned your girlfriend into a while, and you think can try to lose weight behind my back?”



“I’ve put on weight since we started dating though.” He pointed out, although it was a modest amount compared to her.

“Keep it up, senpai.” She said, and was soon preoccupied by the arrival of their food. Haruto quickly checked his phone, doing a rare check of the program. Despite Akane occasionally egging him on he rarely used it these days. After all, what more could he want from her? He could hardly think of anything to add to her, with how beautifully obese and by now naturally gluttonous she was. He checked her affection, now glowing and pulsing as it read 98%. Just what would happen once it hit 100%? Watching this number was the only reason he still used the program, spoiling his girlfriend whenever he could to try to push the number over the edge.

Hibiki Yuuta’s name had long vanished from the list, Rikka not caring for any man but him. He was still a casual friend of hers, but just as Akane had wanted, their relationship had long overwhelmed any lingering crush she might have had on him. Perhaps in another universe he hadn’t been there and their budding romance had blossomed, but here and now it was not to be. A month ago he had finally given into temptation and clicked on Akane’s profile after inspecting just how high Yuuta’s affection was for her, and although he had just as quickly closed it in case her all-seeing eye noticed him, he couldn’t help but notice the fact that she had been discreetly increasing her bust and thigh size over time to fit Yuuta’s tastes.

 When they were finally done Rikka required considerable help standing back up, hobbled by her weight, her ever-decreasing athleticism as she had started to outright sit out gym class, and her pregnancy. She lumbered slowly down the street, sometimes needing breaks just to make it home depending on how long it took. Haruto didn’t mind, always personally walking her home, or back to his place.

“By the way, have your friends noticed yet?” He asked, Rikka having started to get big enough that her pregnancy was starting to show even through her bulky body. Her breasts were getting fuller and her belly was starting to grow rounded, and by the third trimester no amount of weight would be able to hide it.

“Not yet, can you believe it?” Rikka complained, even though she was the one who had decided to keep it a secret for as long as possible. “I should just not tell them until I’m giving birth. I’ll feel better in the hospital knowing they’re freaking out. You can see it, can’t you, senpai?”

“Of course I can. I know every little thing about you.” He bragged proudly, placing his hand onto her belly where his hand sunk in past its plush outer layer to the taut sphere below. Rikka smiled, and the two chatted happily until they reached his home.

“Ladies first.” He gestured, only for Rikka to abruptly stop halfway through the door frame. She wriggled slightly forward, as if trying to push forward fruitlessly.”



“What is it, Rikka?” He asked, and she took a long time to answer.

“I’m stuck.”



“What?”



“I said I’m stuck! Aaaaahhh, I knew I should have turned sideways!”



“C-can you back out?”



“I would by now if I could! Senpai, you’re going to have to push!”



Haruto grabbed Rikka by her huge love handles, her big muffin top making an easy handhold as he grunted, her enormous hips firmly wedged in the doorframe.

“Not there, lower!” Rikka grunted, and let out a girly gasp as his hands sank into her gargantuan ass.

“Harder senpai, harder!” She complained as she failed to make ground, the doorframe starting to buckle around her.

“I don’t want to hurt you! What if you fall over?”



“Just do it! On three! One...  two…”

“Three!”



Haruto called it out as he shoved her through, a cracking sound coming from the door frame as she stumbled ahead, managing to keep her balance and tottering to a halt. Rikka refused to turn around, standing there in silence.

“Did I break it?” She eventually asked, her rosy red cheeks flushed with embarrassment and almost visible from behind. Haruto looked at the door frame, then back to her.

“Let’s not worry about that.” He advised, the door thankfully still managing to close behind him.

“Aaah, I’m so fat, I’m so big, I can’t even fit through doors anymore…” Rikka began to mutter. “It’s not my fault, right? It’s all your fault, senpai. Even though I like it so much, you had a normal girlfriend and you turned her into this.”



She grabbed her muffin top, squishing it as she thrust her belly against his.



“I’m so fat I can barely move, and you went and got me pregnant with your babies. You’re so selfish, senpai, I can’t believe it!”

Without giving him time to speak she kissed him, pulling him into a long embrace that she refused to break as he sunk deeper into her body.

“I love you.”



The two spoke simultaneously the moment the kiss was broken, Rikka’s eyes widening even though she had heard it many times before, then lowered back into a more self-satisifed look, as if unwilling to let him have the pleasure for long.

“I know.” She kissed him again, waiting for him to take her to the bed. She laid back and let him do all of the work, unbuttoning her jacket, her blouse, and then finally pulling down her skirt. He played with her belly gently due to her pregnancy, then her breasts, but she seemed impatient today.

“I want you, senpai.” She mewled, unsatisfied with foreplay, and so he managed to undo her bra and slide her panties off, taking his own clothes off as quickly as he could. She was practically salivating even though she couldn’t see his cock past the slope of her own belly, and he penetrated her with force, Rikka letting out a low moan as he groped her waist, her ass, any piece of fat he could get his hands on, pausing slightly between pumps to lean forward and kiss her.

“Harder, senpai, harder!”

The mattress began to buckle as he increased at her insistence, the two panting and sweating as he put his all into it.

“Ah, ah! Senpai, senpai!” Rikka began to say almost delirious with pleasure as she was totally taken by him, the bed straining under the two’s combined weight, Rikka taking up most of the bed by herself. She repeated it again, until slowly, her words changed.

“Senpai, senpai… Haruto, Haruto, Haruto!”



She cried his name again and again, until finally, with the bed groaning and one last burst of strength left in him, he finished the job, but just as he came inside of her, the bed let out a final wheeze and completely collapsed, Rikka squeaking  as the bed frame broke and the two fell with a crash. The two were dumbfounded, Haruto still inside of her as the moment was completely thrown off. The two stared at each other, totally speechless as they were unsure of quite what to do, Haruto eventually slowly pulling out of her. The two sat there, silent and panting from exertion, before Rikka slowly began to giggle, and he began to chuckle. Her giggling became uncontrollably, as was his, and it wasn’t long before the two were laughing, then practically howling at the absurdity of their situation.

“Well, we were going to need a bigger bed anyway.” Haruto wheezed, rolling over to lay by her side.

“I didn’t know I was dating a gorilla. Geez, Haruto, show some restraint.” Rikka continued to giggle, and for once he couldn’t take it lying down.

“No way, this was your fault. I’m practically skinny compared to you.” He said, revelling in her fatness, as he had long known that she enjoyed it.

“This is why you’re no good, Haruto. Blaming your cute girlfriend for breaking your bed.” Rikka said as if he were a child, letting out a cute pout. “I’m just going to have to be there for you if you’re going to keep being like this.”



“I’m not senpai anymore, huh?” He commented, Rikka having rarely used his name even after he impregnated her. She seemed to take great enjoyment in insisting on calling him that, but by the look on her face, she had finally lost interest.

“You’re going to graduate before me, aren’t you? I had better start getting used to it as your wife.” She smiled, kissing him again.

“I suppose I can get used to it.” He laid back, and the two no longer needed words.

Eventually, once Rikka had finally fallen asleep, Haruto retreated to the bathroom, feeling compelled to check his phone one last time. When he opened up the dating sim, he was greeted by flashing lights and digital confetti, a chibi animation of Akane setting off party poppers as it proudly declared that he had conquered the Rikka route. It seemed that she would get the last laugh after all, and he looked forward to hearing her brag about the finishing touch she had put on the whole project, before she inevitably bragged about how well her own relationship was going.

The clear screen eventually faded, but the chibi Akane avatar remained on the screen as well as a clear notification over the extremely obese Rikka portrait. It seemed that all of the UI options were now non-interactive, able to check her stats but not alter them. The red text he had added had mostly vanished, him no longer needing the ability to tweak her to his whims now that she would never think about loving another man in her life, her affection at max no matter what. Although his compulsions were gone, many of them were now in white text in her other categories, having become a natural glutton who loved being felt up by him. She no longer felt compelled to eat endlessly in front of him, but the program did state that she very much enjoyed him watching her eat.

He was about to finally close the program when his finger lingered over his own name, and he finally gave into curiosity and clicked on his own profile. It was kind of embarrassing to see his own portrait, as well as various factoids about his own life. Rikka would probably kill him if she ever saw her own profile on his phone, he was aware, and this really put it in perspective. He decided to not look at it too closely, save for his own affection, where Rikka was, naturally, also at one hundred percent. Not that he needed some number to tell, for both himself and Rikka.

He climbed back into their broken bed, snuggling up against Rikka. She probably wouldn’t gain weight as quickly now, he guessed, as attractive as the idea was. It would be up to her to decide just how much fatter she wanted to get for him, which was an even more exciting prospect.

Life was good, Haruto thought to himself as he pictured everything the two had ahead for themselves, from graduation to wedding day to married life. He couldn’t wait to see it himself.
