Chapter Text
As Rumi Usagiyama strode towards her collapsed client, she could tell that the poor girl was at her limit. Still, if she was going to whip her into shape, she couldn’t go easy on her.
“Now, Uraraka, what did you learn today?” Rumi asked, standing over the other girl.
“Not to cheat on my diet,” Uraraka whimpered, her voice muffled by the padded mat her face was buried in.
“And what happens to people who cheat on their diets?”
“This,” Uraraka answered, gesturing at her own prone form.
“Good. Now, take tomorrow off. You’ll need the recovery time until you’re as fit as me. If I catch you cheating on that diet, though, it’s gonna be round 2 for you, got it?” Rumi warned. Uraraka nodded and rolled onto her back. Her t-shirt had ridden up slightly to reveal the little pudgy tummy that Rumi was trying to help her work off. Uraraka made a quick hand gesture and began to float, turning off gravity for herself until she was up enough that she could land on her feet.
Meanwhile, Rumi was checking her schedule on her phone. It was almost 5 pm, so she figured that time was almost up for her working day. Sure enough, Uraraka was the last one for the day, and so Rumi could leave. She certainly wouldn’t mind sticking around longer, loving the gym was the main reason she became a personal trainer after all, but she had plans for tonight. As fun as those plans were gonna be, she tried to keep a straight face as she made for the showers and changing rooms. She had a reputation she wanted to maintain as a harsh trainer that ran her clients into the ground, even someone as young as Uraraka, but Rumi didn’t care about that. If anything, it only meant that the clients she kept were the ones who were taking this seriously enough for her to bother with.
She certainly looked the part, with her expertly sculpted muscles being shown off by her skin-tight sleeveless white top and snug short purple shorts. She was the perfect image of fitness, and even if there weren’t many who could catch up to her, she was going to try to drag them along with her whether they thought they could keep up or not. The rabbit ears she naturally sported somewhat confused the image, until she took her clients on a run and they found that, in addition to having boundless stamina and strength, she was also as quick as a rabbit, making it hard for the average client to keep up.
Once Rumi was done in the showers, she changed into something a bit more relaxed, going with a purple corded sweater, a strong contrast to her long white hair, and tan pants, about a shade lighter than her skin. She would’ve preferred something sleeveless, but this cool autumn weather wasn’t quite the weather to have her guns out. She made for her car and made a few orders for food to pick up with her phone. It was far more than she would ever eat, and food that was far less healthy than she would ever eat, but it wasn’t for her, it was for a woman who was very special to her.
As Rumi made her way to her girlfriend’s apartment, she was stopping off at just about every dumpling place on the way there, with a small stack of dumplings waiting for her to pick up at each place she stopped. This wasn’t the first time she had gone on such a dumpling buying spree, and she basically had the dumpling places locations and menus memorised, along with, most importantly, which dumplings from each place were the best. At some places, it was pork dumplings, possibly with something added, at some other places, it was shrimp or vegetables, and there was even a place that did pierogies.
By the time that Rumi had made her last stop, it was almost half-past five in the evening, and her passenger seat had so many dumplings that the seat was pretty much completely filled. Fortunately, the traffic in this part of Mustafu was pretty reasonable at the moment, so she didn’t have to worry about getting stuck in traffic and watching the dumplings go cold. When she pulled into the parking near the apartment, Rumi patted her biceps.
“C’mon Rumi, this is what you’ve been training those muscles for,” Rumi asserted to herself. She scooped up all of the dumpling packages and hauled them up to the apartment building. As she got to the elevator for the building Inko’s apartment was in, she saw that the elevator was out of order. She let out a long sigh that sounded at least a little bit like a growl. “Ah, crap. Alright, gotta hustle or these are gonna get cold” she told herself as she made for the stairs. Sure, she might not have been dressed for a workout, but her quirk made the stairs into barely an obstacle, even managing to skip a few of them at a time. With the stairs being as easy as they were, Rumi focused on keeping her stack of dumplings balanced. It was hard to not focus on that, as the stack piled so high that it almost blocked her view of everything else. Luckily for Rumi, the very small handful of people she encountered on her five flight journey could see her speed and likely lack of awareness, and so they gave her a wide berth as she booked it up the stairs.
When she got to the top, which only took about a minute, she took a moment to catch her breath, a moment that the fit Rumi barely needed, before making her way down the hallway to Inko’s apartment. She transferred her stack of dumplings to one hand and quickly knocked with the other, before going back to using both hands to keep the stack of dumplings steady.
“Coming!” a woman’s voice called from the other side of the door, coming out muffled for Rumi, despite her rabbit ears’ enhanced hearing.
After a moment, the door opened, showing a plump older woman in a pink cardigan. Her dark green hair was tied back in a loose ponytail, with long, thick strands falling down from around her fringe, framing her soft, round face. This was Inko Midoriya, the only woman in the universe, and every universe beyond that, that could make Rumi’s heart flutter with love and excitement.
“Inko! Dumpling! Where’s the table? I wanna put this stuff down so I can hug ya!” Rumi cheered. As soft as Inko made Rumi, that didn’t stop Rumi from being stuck at 100% all the time.
“Oh, Rumi, right here,” Inko said, guiding Rumi to the table over by the window. Inko was about to close the door for Rumi, but before she could even move to do it, Rumi had dashed around to give Inko a big hug, lifting her off the ground, which was not an easy feat, as Inko was just barely taller than Rumi.
“Oof, you’re gettin’ heavy, babe. You’ve been eating well,” Rumi said with a grin, patting Inko’s pudgy belly, which was just pushing out past Inko’s modest chest. There was a small bulge where Inko’s belly spilt over the waist of her snug skirt.
“I’m just taking your advice,” Inko purred as Rumi put her back on the ground. She wrapped her chunky arms around Rumi’s thinner and more athletic frame, letting her pillowy belly press against Rumi’s rock hard abs.
“Hey, babe, don’t go tellin’ others I’m going easy on you,” Rumi said in a low voice.
A little while later, after they closed the door and caught up on chatting, Rumi had the vast array of dumplings set out for Inko.
“Oh, goodness, it looks like so much more when it’s spread out like this,” Inko said, her eyes wide with surprise and a hint of concern.
“Hey, c’mon, I’m sure you can do it. I’ve seen you eat plenty before, this should be a piece of cake for the incredible Inko!” Rumi cheered her girlfriend on while giving her a calming and supporting shoulder rub. A look of determination reached Inko’s chubby face.
“Okay, I can do it,” she asserted, more trying to convince herself than anyone else. “But, um, would you mind if we leave some of these aside for my son? I don’t think I’ll be able to cook for him after this,” Inko added nervously.
“Oh, yeah, totally!” Rumi agreed instantly. “What’s the little guy up to anyway? I don’t wanna make things awkward for you or him if he comes in while I’m feeding you.”
“He said that he would be staying very late after school. I think he was hanging out with some friends of his,” Inko mentioned.
“Alright, good to know,” Rumi said as she set aside a package of dumplings. “Ready to go?” Rumi asked, punctuating her question with the sound of the plastic packaging of a set of dumplings popping open.
“I hope so. I can stop if I want, right?”
“Of course you can. I don’t wanna be like that Fifty Shades creep,” Rumi reassured. She knelt next to Inko and the table, ready to feed Inko. Inko reached out with her hand, activating her quirk and making a dumpling begin to float towards her. Before it could reach her hand, Rumi snatched it out of the air. “Nuh-uh, you’re just gonna relax and I’m gonna do all the hard work,” Rumi made clear. Inko closed her eyes and opened her mouth, letting Rumi get to the so-called hard work.
As the evening went on, dumpling after dumpling disappeared into Inko’s mouth. With one hand, Rumi kept the dumplings coming at a steady pace, giving Inko just enough time to chew, swallow, and get ready for the next dumpling. With the other hand, Rumi was giving Inko’s belly the attention it deserved, fondling it, rubbing it, gently squeezing and playing with it. She didn’t want to go too far out here in the living room when Inko’s kid could be home at any time.
While she was doing all of that, Rumi made sure to encourage Inko, reminding her of how well she was doing, how proud of her Rumi was, and how Inko could defeat this mountain of dumplings.
About halfway through the stack of dumplings, during a very rare quiet moment, Rumi heard a creaking sound, thanks to her enhanced hearing from her rabbit ears. She picked up on the cause immediately, it was Inko’s skirt straining and struggling to contain her expanding belly. She reached around to undo Inko’s skirt but paused right before she got to the zipper.
“Oh, uh, hey, Inko, you mind if I undo your skirt? I don’t want you bursting out of it,” Rumi asked, showing an incredibly rare sign of nervousness. Inko swallowed the dumpling she was working on and took a moment to breathe before answering.
“Yes, please. I hadn’t noticed that until now,” Inko said, shuffling forwards a little bit to give Rumi easier access. Gingerly, Rumi reached around and dragged the zipper down. All of the fat and the stuffed belly that Inko’s skirt was containing poured out as Inko let out a sigh of relief.
“Feeling better, babe?” Rumi asked, giving Inko some more belly rubs.
“Ooh, much better. I think I need a larger skirt,” Inko replied.
“Maybe go two or three sizes up, so you’ve got room to grow into,” Rumi suggested, making Inko giggle slightly. “Wait, what did I say?”
“Oh, nothing. It’s just funny advice to get from a personal trainer,” Inko said with a smile as she shuffled back into position.
“Heh, yeah, good point. I guess I’m the only personal trainer in Japan with good taste,” Rumi joked, before gently hugging Inko’s belly, nuzzling her face against Inko’s belly. “Ready for more dumplings?”
“Ready when you are.”
Even with less pressure on Inko’s belly, having freed it from her confining skirt, it was still a struggle towards the end there. Rumi did her best to encourage Inko, even slowing down and giving Inko more time to eat, rest, and prepare for more dumplings.
Much later, as the last of the dumplings, aside from the one pack set aside, were fed into Inko’s achingly full stomach, the overfed woman let out a groan and flopped back in her chair, making the chair creak as it strained and tried to hold fast against her weight. Her skirt was making similar noises, even after Rumi undid it for her.
“How was that, my little dumpling?” Rumi asked, nuzzling up against Inko’s side.
“You treat me too well,” Inko said sweetly, giving Rumi a tired but genuine smile that made Rumi’s heart flutter.
“Impossible! You deserve the best! You’re a wonderful woman and I love all of you!” Rumi emphatically announced, her fiery red eyes full of sincerity and enthusiasm.
“Well, there is a lot more of me to love now,” Inko mentioned, cradling her full belly.
“Good thing I love you so much, ‘cause I’ve got enough love to cover you no matter how big and beautiful you get,” Rumi reassured. As Inko let out another slightly pained groan, Rumi got up from her seat and prepared to scoop Inko up. “I think we should go to bed, get you more comfortable,” she cooed to her older girlfriend.
“Ooh, be gentle. I’m very full,” Inko groaned. Carefully, Rumi lifted Inko in a bridal carry with ease, her biceps flexing even though this was barely a strain on her arms, she just liked to show off her finely toned muscles for her girlfriend.
“Oh please, like I’m gonna play rough while you’ve got a full stomach,” Rumi said as she nuzzled Inko’s cheek. “I know when to go easy on a girl.” Slowly and carefully, she carried Inko to the bedroom and set her down on the bed, letting Inko slowly sink into the soft mattress. As Inko splayed out on the mattress, Rumi clambered atop Inko, straddling the older woman’s chunky thighs. She watched for a moment as Inko’s belly rose and fell, like watching waves come in and go out. As Rumi reached in, sliding her hands under Inko’s top and feeling Inko’s warmth, she saw Inko’s breath hitch for a moment as she froze briefly. Rumi froze too, waiting for some sort of approval from Inko.
“Oh, s-sorry, I’m okay. My belly gets sensitive when you fill it. I’m okay, you don’t have to stop,” Inko reassured, her voice soft and gentle as she brought her hands to rest on Rumi’s.
“Right, right, I knew that,” Rumi tried to convince Inko and herself, her cheeks going a touch red with embarrassment. A quiet chuckle slipped from Inko’s mouth.
“Oh, honeybun, you’re so adorable when you’re flustered,” Inko teased. Rumi put on an annoyed pout, before leaning in to give Inko a big, deep kiss, cupping Inko’s chubby cheeks, kissing for as long as she knew Inko could hold on for.
Eventually, Rumi released her girlfriend from her kiss, leaving Inko red-faced and panting.
"Hmm, looks like we should work on your stamina soon," Rumi teased right back.
"Sorry, my girlfriend is a bad influence," Inko retorted, sticking her tongue out at Rumi. For a forty-something-year-old, Inko could be quite the little brat, Rumi noted to herself with a small smile.
"Well, how could your girlfriend resist feeding such luscious curves," Rumi asked, turning the horniness way up as she slipped her hands back under Inko's top, before pushing it up to reveal Inko's round belly. "There's this big, round curve," Rumi said in a husky voice as she ran her hands across Inko's belly. Inko let out quiet little groans as Rumi massaged her belly. If she wasn't in the middle of a wonderful massage, Inko would probably be asking for more food if they had any that they weren't saving. Rumi then slid her hands over Inko's belly and down to her sides, running her hands along the curves made by Inko's wide, motherly hips. "And then there are these incredible curves," Rumi said, without a doubt enjoying how much she was making Inko squirm and moan with pleasure.
Once Rumi was done with that, she moved her hands and gently rolled Inko onto her side. Inko's belly poured across the bed as much as it could, a lot of it being held in place by how firm and taut her full stomach was making her belly. However, what Rumi was truly trying to reach was also now exposed, Inko's plump, pillowy posterior. Rumi ran her hand all the way across Inko's rear, a lecherous grin on her face.
"And, of course, this unmissable beautiful curve," Rumi purred, giving Inko's bottom a gentle squeeze, making Inko yelp out a moan. "Mmm, that's a sensitive spot, isn't it?" Rumi teased. Inko whimpered as she nodded. "Well, when you make those sexy noises, I think I know my favourite spot," Rumi punctuated with a gentle spank. Inko barely felt it, due to her generous amount of padding, but she was still sensitive enough to let out another moan, longer and more enthusiastic, as her jelly-like rear jiggled energetically. The jiggle only heightened the pleasure for Inko, as her face went red and her grip on the sheets of the bed tightened. Inko was panting and her heart was racing as Rumi rolled her back over onto her back. Seeing Inko like this was just too much for Rumi, and it sent her over the edge. She crawled on top of her fat girlfriend, putting herself face to face with her. “I love you so much,” Mirko whispered to Inko as she leant in. She placed long, slow kisses on the side of Inko’s neck, running all the way down to her collarbone, which was covered in enough fat that it was impossible to actually see clearly. Then, she ran her kisses all the way back up Inko’s neck to her soft jawline and blubbery second chin. Inko held her tight against her expansive body, feeling Rumi’s warmth and firm muscles, which contrasted completely with the fat that made up a large amount of Inko’s body.
“I love you too, Rumi,” Inko whispered back, her eyes not really focusing on anything in particular as Rumi kept peppering her with kisses. One of Rumi’s hands moved down to start rubbing Inko’s expansive belly again, pulling quiet, gentle moans of pleasure from Inko’s lips.
The couple stayed like this for quite some time. How long it was was unclear to either of them, as they had hardly been keeping track of time. They might as well have been in another universe, where what was happening down on Earth barely mattered to them. All that mattered to either of them was each other.
At least, that had been the case until now.
“Mom! I’m home!” a teenage boy’s voice called out from outside Inko’s bedroom, followed by the apartment’s front door closing. Both women immediately shot up, and Inko quickly fought with her clothes to cover up and make herself decent for her son. “Oh, wow, this was a lot of food! Did your girlfriend visit?” Inko’s son asked.
“Um, sorry Izuku, I forgot to mention that she was visiting,” Inko called back, before poking her head out of the bedroom. Her belly pressed against the wall by the door, but it was fully hidden from Izuku. From her mostly hidden vantage point, she noticed that she and Rumi had left the table almost completely covered in food packaging, and Inko winced at the mess she had left for her son to see and that she would have to clean up later.
“That’s okay mom,” Izuku dismissed with an easy smile. “Oh, uh, can I have these dumplings? I had to stay late at school to get some work done and I haven’t eaten yet.”
“Please, have it. We saved it for you,” Inko explained, her smile becoming slightly strained, as the pressure on her belly was starting to become uncomfortable.
“Is your girlfriend still here? I can eat in my room if she is, and you two don’t have to worry about me,” Izuku said as he walked towards his and Inko’s separate bedrooms. Rumi contemplated whether she should hide or make herself known, but Inko answered that question for her.
“Well, uh, she is here at the moment, but we were hoping for some privacy tonight,” Inko answered sheepishly.
“That’s okay, I’ll leave you two alone,” Izuku reassured as he moved quicker, disappearing into his room and shutting the door quickly behind him. As soon as that was over, Rumi and Inko both breathed a sigh of relief. Inko ducked back into the bedroom and shut the door behind her, returning to bed next to Rumi.
“Man, that was awkward,” Rumi said, somewhat bluntly, as she sat up in bed, resting her back against the wall.
“S-sorry honeybun, I lost track of time and…”
“Inko, sweetie, it’s okay,” Rumi interrupted to reassure her girlfriend. “I got a little distracted too,” she also admitted as she put an arm around Inko’s broad, sloped shoulders.
“Well, maybe… next week you could join us for dinner. Maybe not a dinner like the one we just had, though, but a proper family dinner” Inko suggested. It was hard to leave Rumi properly speechless, but Inko had just managed it, leaving a stunned look on Rumi’s face. Rumi wasn’t sure how to respond to that. It took a good few seconds for Rumi to even manage any sort of answer.
“F-family?” Rumi asked in a state of uncharacteristic nervousness.
“I mean, only if you’re comfortable with it. I just thought it would be nice for my son to meet my partner, and I had hoped that… well… we could make this a more serious thing.” Rumi was stunned for a moment, but then she broke into a big smile.
“I’d love that!” Rumi cheered.
“Really?” Inko asked, a hopeful smile on her face.
“Yes, really! I already wanna pamper and treat you, and I’m ready to start taking this seriously,” Rumi said with sincerity and confidence. “I’m gonna be the best girlfriend you’ve ever had!” she declared, punching the air with excitement.
“W-well, you’re also the only girlfriend I’ve ever had,” Inko sheepishly added.
“Best partner, whatever, I’m gonna be the best,” Rumi corrected. “And I think I’m gonna start by rubbing that belly until you’re feeling all better.”
With that, Rumi and Inko spent the evening together, snuggling together, looking forward to their future together, whatever that may hold. One thing was for certain, though. Rumi was going to pamper and treat Inko as much as possible for as long as possible.
