Chapter Text
Katsuki walked into his shared apartment, paused at the door to remove his boots and hoodie. He tossed his keys on the little table by the door and took notice that only his set was there in the box shaped like a coffin that houses everyone's set of keys. Good, he can get some work done at home without any distractions.
He's had one hell of a day. Nothing happened. At all. Which is a good thing when you're a pro hero. But bad when you're an explosive man with no patience and already went to the gym before work to get your aggression out. Well most of it. Some of it. He went to the gym.
It wasn't his day to do patrol. Eijiro had meetings all day, so Katsuki couldn't join him on any of his patrols. And you? Well you're the damn problem. So what did he do with his time? Thought about you of course. Which was a good thing and a bad thing at the same time. Good because he finally got to sort out his feelings in his head, sort of. Instead of just telling said feelings to "die" and stuff them away like usual. Bad though because he sees now that he's head over heels for you.
He'd been in denial about it and trying to justify his reactions, and feelings for several hours and trying to convince himself that he wasn't smitten with you. By the time he was sitting in his office staring at the wall with a blank stare, reeling over the fact that he couldn't justify or deny his reactions, he realized it was time to go home. And thus his entire day revolved around you, without you even being a part of it. He just wanted to come home, with no distractions and think about something else.
Those distractions being you and Eijiro, but mostly you. You, Eijiro and Katsuki have been living together for a while now. The decision was easy after you all had become somewhat of a trio in high school. You and Eijiro were close growing up, before high school, and stayed close throughout U.A. Once in U.A. Eijiro and Katsuki began getting close as best buds, you not only understood the need to have a fellow guy around for Eijiro, but you welcomed Katsuki into the group and accepted him just as he was. Brash, impulsive and quite literally explosive.
The two boys have opposite personalities and you've always treated them as such. No bullshit attitude for Katsuki mixed in with charm, patience and understanding, and Eijiro got tough love, motivation and a softer side to you that Katsuki has yet to fully experience himself. He knows you two have always been close, so to find you two cuddling on the couch together under a shared blanket, or him giving you a piggyback ride, or arms looped through each other is not uncommon. He doesn't see motivation from either of you for a relationship there, just that you guys act just as you did as kids, only now you're adults.
He honestly wishes he had that with you too. He's human, he craves closeness and touch as well. From you at least. But his motivations are different from Eijiro's. Maybe he just needs to make the first move to let you know that it's ok to do it with him too. That he won't bite. He likes you a lot and doesn't want to push you away. Maybe he likes you a little too much. You two are his whole world, and he'd have to murder anyone that ever found out, but he'd do anything for you guys. If only he had something he could use to be closer to you. Like how Ejiro is. Not because he's secretly desiring your touch or anything like that. Or jealous. Definitely not jealous. Nope. Die feelings!
He padded on socked feet across the expanse of the large apartment making his way to his room. He placed his lunch box and water bottle on the kitchen counter as he walked by it. He'd deal with it later, he told himself. He walked down the long hallway that was littered with family photos from all three of you guys. You insisted it feel like a home, and to make it fair all of you had to have embarrassing family photos on the walls. You were right though, it did make it feel more like a home. He paused and looked at one of you three in your first year of high school, sitting together at a lunch table. He remembers this picture. Mina Ashido came running up babbling something about needing to keep memories and told everyone to smile. You and Eijiro lit up with big smiles, but there's Katsuki, scowl on his face. Has he always been this way? This is probably why people don't approach him. He should work on that. On second thought. Good, keep it that way. Less distractions, and obstacles, damn extras need to keep their distance. Man, no wonder why you don't make the effort to be closer to him. You probably are afraid of being bitten.
It's been more frequent that he notices little things that you do too. You've always done them, but now he's more aware. The way you smile at Eijiro is different from how you smile at him. You're not afraid to touch Eijiro, either it be running up and squeezing him in a bear hug, or simply resting your hand on his shoulder as he's showing you something. He reciprocates as well, tickling you, playfully throwing a mocking punch at your jaw, throwing you over his shoulders like a sack of potatoes. You guys have always been this playful so he doesnt think it's flirting. But would it be flirting if he started doing the same? What if he picked you up like you weigh nothing and tossed you on the couch just for fun? He should start with small things first, encourage you to do the same. Still not jealous. Right now though, he needed a distraction from you. He's been thinking about you too much lately. So getting some work done at home would be good for him. He can just throw himself into that and close everything else off. Especially since he managed to not get very much done today at work.
He went into his room and pulled out his desk chair, taking a seat he pulled out his laptop from the laptop bag that had been laying on top of his desk. He opened it up and tried turning it on only to soon realize it was in fact dead. He dug around the desk drawer, looked behind the desk, under the bed, the pile of laundry he has been ignoring for a week, his laptop bag, but to no avail. He couldn't find the charging cord. "Damn, shitty hair must have borrowed it again."
He left his room and headed over to yours which was directly across the hall. It wasn't like him to invade someone else's privacy, he respected everyone else's and expected it in return, but he knew you wouldn't mind if he borrowed your laptop while you were away. Better to ask for forgiveness than permission right?
He lightly tapped his scarred and tattooed knuckles against the door before slowly opening it just to make sure you were indeed not home. He looked around your room, it wasn't very often that he came in here. It suited you greatly, a cross between heavy metal chick, gamer chick, nerdy girl, some girly girl and a Tom boy. Bed of course not made, plushies of bats, fat cats and random food items like a hamburger lay scattered across your bed. Fandom artwork from some of your favorite tv series, movies and anime were strategically placed on the walls. You had a gothic style vanity opposite your bed with the mirror having pictures tucked away in the mirror frame. One of them being all three of you in a drunken state smiling at the camera and flexing your biceps for the picture. You being in the middle with a scrunched up face, yet still smiling, trying to look as big and bad as the boys. You also had a pile of laundry in your room, but yours was piled in an actual hamper at the foot of the bed. Mostly holding graphic and band tees in a massive sea of black. He could see lace thongs tossed in there as well. He smiled devilishly at that. And your room smelled like you. Vanilla, he knew it was your favorite scent and flavor. Most people think of vanilla as boring, not you though. You see it as very sweet, yet it could also be a great base to add anything to when it comes to food, without it destroying flavor profiles or overwhelming them. Or so you've said at least.
He walked over to your desk, pulling out the chair, and sitting down. "Jesus fucking christ! Is she a fucking midget?!" He very damn well knew that you weren't but damn this chair was up very high. He reached down on the right side of the chair to adjust the height of it. Once he wasn't what felt like ten feet in the air, he slid your laptop towards him. You all worked at the same agency, so he knows you have access to their site and any intell he may need. He pulled it open and the laptop was just in sleep mode. He wakes the computer up and the background is a damask design with skulls intertwined in it. All different shades of your favorite color.
He sees there's already a browser tab open, he figures he'll just open another tab. He clicks on the browser icon and sees tumblr. He's about to click on the plus icon to just open another tab when he notices the page is in editing mode. Oh, so this is her tumblr. He didn't know you had one. If anything has been posted on tumblr then it's technically open to the public eye so he's really not snooping, as he intends to scroll through your posts you've made. Why? He's just curious, that's all. Thus continuing you distracting him from his work.
He sees your header and is immediately taken aback. Reading the anagram "FFA". He knows what that means. He's dabbled in kinky stuff before with other people. Liking thick people was pretty common nowadays. "So she's a fucking chubby chaser." More of a statement than a question. He would have never guessed that about you. Yet, here lies evidence in front of him, of stories you've reposted and liked, drawings of celebrities, heroes or original characters with big bloated bellies. He frowns as his hand immediately goes to his rock hard abs. Never did he think abs would be not desirable by some people.
But this, this could be what he's been looking for. Get inside your head, get closer to you by knowing something about you that obviously is not shared between all three of you. Could it be an invasion of privacy? Yes and no. It's publicly written and posted, but at the same time you haven't shared any of this, least not to him. He brings his attention to the most recent post on your page.
Anonymous asked: You have so many different kinks on here, why can't you just choose one?
Your reply: It is a bit confusing to say the least! But it all kind of relates and or connects to one another in a way really. I think I technically have a size kink. Hear me out, it all ties together. Like let's start with the simple things. I love me a tall man. The taller the better.
Bakugo smirked, he had no issue there while standing at 6'3.
The way a guy looms over you, calls you "shorty", picking on you for being so small is my literal form of flirting. Now add that he's buff too. So he can toss you around, if you get my meaning, his hands engulf yours, he points out how your shoe could literally fit inside his, how he cages you in with his big arms either against a wall, or underneath him. Basically anything that makes me feel small compared to him. That's where the giant/tiny kink comes in.
The what…?
The idea of a giant man taking care of you. All that strength and mass and he adores you and cherishes you as his little treasure. It's like sickeningly cute. Especially since giants always get a rap for being hostile and yet there he is keeping you, like a pet. Here is where the vore comes to play.
What the absolute fuck?!
There are multiple kinds but we're just gonna focus on two for right now. G/T dynamic and same size. I'm more partial to same size. Only because it tends to give the predator a huge belly. And you all know I love a big belly. It can happen with G/T scenarios too, but I'm more about the size outcome for vore then anything else. I don't really care for the sound effects, digestion, etc it's just all about the huge gut.
This is insane. He's living with a girl that likes vore. He takes a deep breath. Don't kink shame Katsuki, be understanding and keep reading.
That being said, this is why I like predatory behavior in men. When he licks his lips, when he wants to "ravage you", "taste you", looks at you with "hungry eyes", etc.
Ok, he'll admit he's used some of those lines before in the past with others. He can't help it! He has natural predatory behavior!
Showing me your canines as you lick them? Instant puddy in your hands.
Huh… I'll keep that as a mental note.
Now, take all of this and add a gut to him. So he's got all this power, strength, dominance, literal appetite and a big round belly to feel up on. Heaven sent.
Well, when you put it that way it actually does sound appealing. He likes and has all those things. Except the belly of course.
My favorite body type is kind of like a body builder that's indulged too much. Or a former athlete that's starting to let himself go. So he's got a nice layer of fat while still being huge with muscle but he's got a gut that can crush a man. So like the pro hero Fat Gum, after he's used up all his fat storage and has started to put it back on. Like that stage. Super hot.
The idea of you looking at another male pro hero that way bothers him more than it should. But this explains why you're always so giddy when Eijiro brings Fat Gum around after staying in touch all these years.
So that is why I have all these different posts and kinks on here. To me they're all related in my twisted mind. So twisted that I made this blog as an outlet and my kinks will never see the actual light of day with any body.
That's kind of sad really. Maybe you just haven't found someone you feel like you can be one hundred percent honest with about what you like. Hell, even he has kinks. Everyone has something they're into. He wonders if Eijiro knows about any of this. You've been friends for more than half your life. He's always been a tad bit jealous of how close you two are. Wait, no he's not jealous. That's right. But only lately is he finally understanding that it's because he has feelings for you and not because of the friendship itself. And now after finding this, he isn't sure how to feel about all of this. So, researching it is, the more he can find out, the better advantage he'll have. He scrolls down to another post.
Anonymous asked: do you have any favorite fan fictions of pro heroes?
Your reply: I have a lot of favorites. But these two are by far my favorites. Going Soft by ChubbinLovin and Bigger is Best by MuscleChubBoi. I love both of these for different reasons. Going soft portrays the main character, Katsuki Bakugo,
It's about me?! She's reading kinky fanfiction about me…. Well, of course she is, it's me.
and how he accidentally let's himself go. Upon doing so he realizes that he likes it. The girl he fancies certainly does and a relationship ensues. It's the little things I love about this story. His ever expanding waistline, too tight clothing, breaking a chair, dreaming about being fed, his apparent desire to stuff himself constantly, and then his way of teasing the girl once he finds out that she's into too.
He would totally do that too. Oh, and he's going to now that he knows this about you.
The other one is a BakuDeku story.
Not this shit again…. Though that's both stories including him. Interesting.
Who he's with is not what I'm all about with this short story. Although I'll admit I'd love to be part of a throuple in this story. Both men bulking and getting to be a part of that would be heaven. But, sadly they're both Pro Heroes,
Ah… she's pretending to be a normal citizen.
both way out of my league, and although I may have had a chance if I were a pro hero, with one because he's too sweet for his own good, He's currently in love with someone else though, and I'm not about ruining lives and love with other people. And the other one, well he's intimidating. In a good way, but also in a way that makes me feel like I'd never stand a chance.
Well that's not how he wants you to feel. That you're not good enough for him. He's flattered as hell, but also mad, because you deserve to feel like you're the best and actually deserve the best. Because to him, you are and do.
Anywho, the story basically follows them bulking as pro heroes. Deku's is pretty straight forward but Bakugo's has different results. Let me tell you this would be a fantasy come true. His confidence, sex appeal, dominance, size, just everything about it! His appetite for food and becoming bigger is insatiable! And its fucking hot!
Katsuki blushes at reading you calling him, well sort of him, hot. This intrigues him to read the stories you've linked. He's curious to know what has you fantasizing about him.
He clicks on the links and thoroughly reads the stories. Something catches his attention though. In the one about bulking it mentions that his fire power is increased, but recoil and pain reduced due to his size increase and fat accumulation. He wonders if it has any truth to it. He reaches into his pocket and pulls out his phone. He pulls up tumblr, goes to his own secret account… because kinks, makes sure to follow your account and turn on notifications. He finds the link and sends it to the one person who he thinks would know if that would hold true or not. He'd been thinking about bulking up in muscle mass anyway lately.
Hey Nerd, read this and tell me if it holds any merit.
He attaches the link and sends the text to Izuku. Just then he hears keys in the lock at the front door. He quickly puts your computer back to sleep, pockets his phone and reaches to the side of the chair and puts it back to midget height and quietly exits your room shutting the door behind him. Best to not give away that he's found out about your tumblr.
He can hear you and Eijiro walking in together, and the sound of rustling bags. You two must have gone grocery shopping. Good, now that he's found your secret, this is a good opportunity to test if it's true or not. Your kink that is.
He walks out to the kitchen where you and Eijiro are putting the bags on the counter and digging through them to put stuff away. He comes up next to you and peaks in the bag in front of him. "You got good stuff right, none of that frozen shit?"
You chuckle a little, which causes him to look towards you. He loves your sweet chuckle. Wouldn't admit it, but it's especially best when it's caused by him. "Yes, everything is fresh and everything will be made from scratch as always."
He gives you a toothy smile, "good because I'm starving! Worked up a major appetite today!" He makes sure to pat his stomach while saying this. Obviously a lie as he sat on his ass all day in civilian clothing.
He catches your eyes darting to his stomach and sees a mild flush on your cheeks before turning away while squeaking out a barely audible "...oh?"
He turned his back to the counter and leaned against it while crossing his arms over his massive chest. "Yup, I was thinking of bulking up a bit too. So I'm gonna need lots of calories." Which wasn't entirely untrue. He was still on the fence about even the idea of getting fat, but he wasn't opposed to the idea of added muscle at least. He did see you pause as he said this. How you literally stopped moving and he could see you swallow nervously. Oh yeah, I've got her attention.
"That's awesome bro! Maybe I should do the same! We could compete to see who gets the bigger gains!" Eijiro added being unaware of Katsuki's intentions of riling you up. He then flexes his arms and pats the muscle on his bicep causing you to lightly chuckle again.
Never one to turn down a challenge, Katsuki flexes his bicep too and then winks at you. "You know I'll win." Stated as a fact.
And rile you up it did. You stumbled as you were walking to put something in the fridge and almost dropped what you were carrying. This time it was Katsuki's turn to chuckle as he reached forward to steady you by holding onto your arm. "Easy there Shrinky Dink." You smiled up at him while muttering a soft thanks to him. Gods she's too cute. You looked down, to see him still holding your arms as he helped lift you up from stumbling. The mild flush came back to your face, as you lightly smiled and turned to face the refrigerator again.
This couldn't be more perfect, he thought to himself. It would be like your favorite story. And you actually get to witness it. Living with two bulking males that already have a large appetite as it is. But of course he wanted your attention on him and not Eijiro. Still not jealous. So he'd always have to push himself harder to keep your eyes on him, and only him.
Just then his phone buzzed alerting him that he got a text.
Nerd: uh, Kaachan about the story… I mean I'm glad we're friends and all again but I don't uh…. feel that way about you, and I have a girlfriend now…. And I'm sorry if this hurts ya know but I gotta be honest
Katsuki rolls his eyes, he was so quick to send the text and leave your room he really didn't give much context to Deku about what he was asking.
No nerd. The part about me bulking and getting bigger, causing recoil absorption and more powerful blasts.
He put his phone down on the counter to wait for the reply and went about putting his lunchbox away and rinsing out his water bottle. Once done with that he started helping put away the groceries. Then he heard the notification and the phone vibrating on the counter top.
"Get a girl's number?" Eijiro teased, as Katsuki went to his phone.
"Do you even know what that is?" He teased back.
Nerd: oh! Well yeah, extra muscle would definitely help with the recoil of your larger and more powerful blasts. The fat would also act as absorption and would also help with build up of your sweat. Essentially you could forego the gauntlets if you were to get this large as in the story. You'd be able to move faster and farther with your blasts as well. Basically unstoppable once your momentum picks up. Any impact you would cause would be severe enough to cause a huge radius of destruction…..
Katsuki stopped reading after that. That's all the motivation he needed. He held his phone in his hand, seeing his reflection on the screen. He saw his sharp jawline, and immediately had thoughts of you kissing at it as it softened. Could he really do this? In both stories it was by chance that he got heavier. This is a conscious decision and not to mention real life. Although he's always been about control. So if it were gonna happen it would be by his terms. But this was you and this could be the one thing that brings you closer to him. Not to mention the absolute badass he'll become. Well, even more of one. It was decided. Katsuki Bakugo was gonna get fat. And he was going to make you fall in love with him as he did it. He looked over at you chatting with Eijiro and smiled. Yup, you're gonna love him whether you want to or not. He'll make damn sure of it.
Ok. I'm still on the fence about it so don't mention it to anyone. Also, what's this about a girlfriend?
He wasn't really on the fence about it, he already made up his mind, but he didn't want it getting back to you. Not yet at least.
Nerd: well uh, I finally asked Ochako out and she said yes! That was a while ago though. We've been dating for a bit and made it official the other day!
Finally grew a pair huh? How about we all go out to dinner tonight. You two, shrinky dink, hard hat and I to celebrate?
Nerd: Kaachan that sounds really nice. That new restaurant just opened down town. Be there at 7?
7's good.
He looked up from his phone, "oi, fuck faces! Get ready, we're going out tonight!"
