Chapter Text
Bakugou let out a soft moan as he licked his fingers clean, one of his hands rubbing the taut dome of his stuffed belly.
It was the middle of the night. He couldn’t sleep due to having skipped dinner from the exhaustion of his internship. The second he came back, he headed straight to his dorm room and fell asleep the second his head hit the pillow.
And now he was in the middle of the kitchen with nobody around, having just finished two whole tupperwares worth of leftovers.
He patted his belly in satisfaction, mouth turned up into a pleased smirk. He was beyond stuffed. He had never eaten such a large amount of food in his life. Always prioritized a healthy and balanced diet.
But this– this was a total carnage. He placed the empty containers in the kitchen sink along with the utensils he was using. Both containers were licked clean. Not a single crumb was left. Every single drop of food was packed tight into his gut.
Bakugou then made his way to the couch. His movements were slow, both hands cradling his large belly that was weighing him down. He rubbed his sides lazily, letting out an unashamed belch and licking his lips as he slapped a hand down onto his gut.
He sunk into the couch, leaning back and lifting his shirt up under his chest, leaving his bloated stomach exposed. He ran both hands up and down his belly, sighing in pleasure at the relief it gave him.
His belly gurgled, pockets of air tightening some areas of his belly. Bakugou pressed a hand down on those spots and burped loudly. He groaned, pulling the band of his sweatpants lower and watching his belly pool out even further.
He felt huge, and weirdly the sight and feeling of being overfilled turned him on. He sunk even lower into the couch, rubbing his gut lazily and basking in the sounds of his stomach digesting the feast he just had. He let out a few more belches, then closed his eyes.
All that food was starting to make him feel tired. The hardness tenting his sweatpants left forgotten, the hand lethargically rubbing circles on the smooth surface of his stuffed belly slowed.
That was until the sound of the elevator door opening and a familiar voice calling out startled him out of his reverie.
“Hello? Is someone there?” Bakugou heard his classmate call.
He hastily tugged his shirt down and quickly realized that it won’t go any lower than his belly button. In a state of panic, he snatched the blanket that was folded over the arm rest and threw it over himself haphazardly. It was messy but it concealed his obviously bloated midsection perfectly, just as a familiar redhead showed his presence in the common room.
”Oh, Katsuki! What are you doing down here this late at night?” Kirishima asked, concern lacing his words as he plopped down beside Bakugou, lifting an arm on the backrest of the couch just behind Bakugou’s head.
Bakugou swallowed nervously and tried not to seem like a guilty man who just ate three whole meals worth of leftovers. “Nothing,” he said dumbly.
Kirishima stared at him in contemplation and Bakugou stared back, wide-eyed and anticipating an answer. His palms sweated even more than the usual amount.
Kirishima took a few more seconds before he said, “Are you sure? Actually, we didn’t even see you during dinner, man. You must be hungry, right?”
Bakugou let out a short, humorless laugh. Hungry. A huge understatement for what he had been just half an hour prior to this. He could still feel the food digesting inside of him and had to restrain rubbing his poor belly, as to not draw any suspicions.
“No. Just ate, actually,” Bakugou replied, to which Kirishima nodded in understanding.
It was quiet for a bit before Kirishima spoke up again, “You had the leftovers? I helped Mina cook, since you know, you weren’t here and all. I know we’re not the best, but I was pretty proud of the results!” Kirishima smiled. “Did you like it?”
Did he like it? “Yeah. It was good.” More than good. He was impressed at the new gained knowledge that his friends—who normally suck in the kitchen—cooked something so damn delicious. Bakugou’s eyes trailed down to his belly that was concealed under the blanket. He licked his teeth, the faint taste of tonight’s dinner coated his tongue and he held back a groan. Mm, fuck.
“Are you tired? Because of the internship, and all. You should tell us how it went tomorrow at lunch time, man!” Kirishima said excitedly.
The mention of lunch nearly made him moan out loud. The thought of stuffing his belly full of delicious food again made his eyes flutter for a split second.
Bakugou nodded and made a small noise of agreement before leaning his head back and closing his eyes. He felt his hair make contact with Kirishima’s arm, and he could distinctly smell the slight hint of Kirishima’s body soap.
Kirishima let out a small chuckle at the sight. “Dont fall asleep on me, man.”
Bakugou opened his eyes just so he could be sure that his friend saw him roll his eyes. Unfortunately, the action made Kirishima’s smile widen even more. “Why’re you even up anyway?” Bakugou asked.
“Dunno. Went to bed a little earlier than usual and just randomly woke up. You?”
Bakugou nodded. “Mm, woke up ‘cause I was…” he bit his bottom lip in remembrance. “hungry.”
”Got your fill though, didn’t you?” Kirishima asked, his voice low and slightly gravely from sleep, sounding almost intimate. When Bakugou turned his head to look at him, Kirishima was already staring right at him with a soft smile on his face. His piercing red eyes made Bakugou falter, paired with the fact that Kirishima had somehow shifted closer during their conversation. He then tilted his head, awaiting the blond’s response.
Bakugou cleared his throat and hoped his voice didn’t sound too broken. “Yeah, I…” he let out a shaky breath. “I’m fuckin’ stuffed.” he finished off, almost a whisper.
He heard the way Kirishima’s breathing stuttered in his throat, saw the way his hand twitched like he wanted to reach out. “Yeah?” he rasped out, “You left the light on in the kitchen. I saw the containers in the sink.” He paused. “Fuck, Katsuki. That’s way more than enough for just one person.”
All of a sudden, a well-timed hiccup forced itself through Bakugou’s chest, loud and uncontrollable, breaking their intimate bubble. Bakugou whimpered and his hand shot up to instinctively cradle his belly. The movement caught Kirishima’s eye. The attention on his stomach, even covered, made his cheeks flush even warmer.
Kirishima didn’t say anything. Bakugou watched as his hand moved to the blanket, and before he knew it, his overstuffed belly was exposed.
“Holy shit,” he heard Kirishima whisper. Bakugou couldn’t help but whimper pathetically, partly in humiliation and partly in arousal. “Katsuki, this is…” he trailed off.
Kirishima audibly swallowed the saliva that had pooled in his mouth. He was visibly squirming in his seat because, fuck. The sight was like nothing he’s ever seen.
Bakugou was beyond stuffed. His stomach was packed full of food, so much so that his abs were no longer even visible. It was visibly tight, and Kirishima couldn’t help but wonder what it would feel like underneath his hands.
So he killed that curiosity. He reached out and lifted the bottom of Bakugou’s shirt up, his movements almost desperate, and was met with his smooth, round gut.
Bakugou didn’t do anything to stop him, just melted further into the couch with his hands lying lazily by his sides. He watched as Kirishima’s hand finally made contact with his skin, and let out a relieved moan.
His hand was not only warm, but big as well. The feeling sent shockwaves down his spine, which lead to him slightly arching his back and pushing his belly further into Kirishima’s hand.
The increased pressure made him let out a large–
“uuuUUUURRRRPP— Fuck, s’cuse me.” Bakugou said, before patting the side of his engorged midsection and moaning. Kirishima sat there, dumfounded yet painfully turned on.
“I’ve never… seen you eat this much.”
Bakugou opened his mouth to reply, but his belly grumbled and another large burp escaped. His eyes fluttered in pleasure. “Mmh, yeah. It was bigger earlier. Tighter, too. Been digesting for the past hour or so,” he grabbed Kirishima’s hand and brought it to his lower belly. “S’bit softer there, compared to earlier.”
Kirishima nodded, his breathing hastening as he lightly squeezed the softness under his hand. The rest of his belly was still taut, so he wondered how big it was before.
“Go ahead. Rub it properly.” Bakugou gestured. Kirishima couldn’t deny such an offer. His hand stroked large circles over his belly, feeling every gurgle vibrate under his palm. Bakugou was clearly enjoying it, biting his lips to contain any sound of pleasure that wanted to escape. Kirishima scooted closer as Bakugou sunk impossibly deeper into the couch.
His side was touching Bakugou’s now, from their shoulders to their thighs. He rubbed a little more firmly, hoping to coax out more burps.
“Fuck, feels so good– BUUAAARRRRRPPPP!” He moaned in relief at the pressure being released. Kirishima patted his belly, albeit a little shy but firm.
“Such a big belly,” Kirishima whispered in awe, his hand rubbing larger strokes over his dome.
”Yeah? You like it?” Bakugou gloated, pushing his stomach out even more.
Kirishima nodded, flustered, pink blooming high on his cheeks. “Would it be weird if I said that I wanted to see you like this more often?”
Bakugou huffed out a small laugh. “Tomorrow.”
”Huh?”
”We’re eating lunch together tomorrow, aren’t we?” Bakugou said.
Kirishima’s confused expression turned into one of realization and understanding. Right. They had class tomorrow, and like every other day of the week, they had lunch together with the squad.
“Actually,” Bakugou started, his hand coming up to knead the side of his big belly. “I’m kinda hungry again.”
“Katsuki, what—” Kirishima spluttered. “You’re joking, right?”
Bakugou simply smirked. He got up off the couch, then paused to catch his breath. His belly was still full, not as much as before but it was heavy. Once he got used to the weight, he marched over to the kitchen.
“I’m gonna raid the fridge,” Bakugou called out, “You coming, or what?”
Kirishima sat still for a few seconds before his brain processed what just happened, then got up to his feet and quickly made his way over and entered the kitchen just as Bakugou was pulling out something.
A cake. Well, half of it. It was made two days ago by Satou, for some celebration or something. It looked rich in chocolate, coated with an icing which also seemed to be some sort of chocolate butter cream. Something impossibly sweet.
“You’re… not gonna eat the whole thing, are you?” Kirishima asked hesitantly.
Bakugou shook his head. “Don’t wanna make myself feel sick.” He ran a hand over his stomach. “Might eat half, though.”
”Half–?! Katsuki!”
“What? Don’t think I can handle it?” Bakugou goaded.
”Not that. S’just not very healthy, is all. And I know you care about that. Besides, I thought you didn't have a sweet tooth.” Kirishima explained.
“Whatever,” Bakugou huffed, “I’ll have one slice.” He grabbed a knife from the drawer and started cutting himself a piece. A large piece. He plated it, then grabbed a half-full jug of chocolate milk from the fridge as a last minute decision. Kirishima stared at him, exasperated yet simultaneously turned on.
“Let’s go to my room.” Bakugou commanded. They both entered the elevator, plate and jug in hand. Only the sounds of the elevator lifting them up and Bakugou’s groaning stomach filled the space. His belly was still out in the open, he hadn’t bothered pulling his shirt back down. Kirishima tried his hardest not to stare
After a short ride, they finally made it to Bakugou’s dorm room. Bakugou settled down in his bed, leaving a space for Kirishima to sit next to him. Bakugou placed the plate in his lap and left the milk on his bedside table. Kirishima sat there with his hands over his thighs.
“Well, what are you waiting for? Fill me up, Eijirou.”
Kirishima felt all the air in his lungs leave him at those words. Wordlessly, he lifted the slice of cake in front of Bakugou’s waiting mouth. He didn’t bring any utensils, so the thick chocolate stuck to his fingertips.
Bakugou took his first, greedy bite and groaned at the sugary taste. Kirishima was right, he didn’t have a sweet tooth but he could appreciate the effort that went into this cake. It was no doubt chocolatey, but delicious nonetheless. He felt the moist layers coat his mouth, and he swallowed thickly.
He opened his mouth again, urging Kirishima, who stuffed it eagerly between his lips. The slice was big and the cake had layers. Every crevice of his mouth was filled. He swallowed again, feeling the thick chocolate slide down his throat and into his belly.
He took a second to breathe. His hands crept up the sides of his already stuffed belly, hoping to soothe the tightness. He was only two bites in and he already felt the consequences.
“You aren’t getting full already, are you?” Kirishima asked, his voice almost a whisper and brushing Bakugou’s ear. He let out an involuntary shiver.
“No.” He shook his head lightly.
“Good. You gonna continue eating, then?”
Bakugou whimpered and nodded, his mouth opening wide. More cake was forced through, and each swallow left his belly feeling heavier and heavier.
“That’s it. Such a greedy belly.” Kirishima’s free hand came up to rub the taut crest of his stomach. He could feel how heavy it was, his fingers refused to sink in despite his best efforts. He was truly, thoroughly stuffed.
“Eiji… fuck. M’so full,” he whimpered pitifully. “uuurrp.”
“You’re doing such a good job. Just a few more bites left.” Kirishima praised.
Bakugou’s mouth chewed on autopilot for the next few final bites. His eyes were glazed over, and he couldn’t break Kirishima’s eye contact even if he tried.
“Last bite.” Kirishima muttered, not wanting to break the intimacy between them. Bakugou’s mouth opened for the last time and he shoved the final piece in. It was smaller than the rest of the bites, and he swallowed it with a moan. He even went as far as to lap up the residue from the tips of Kirishima’s fingers, who breathed out a shaky exhale at the sight.
Once Bakugou was done, he leaned back, slapped both hands on his rounded belly and let out a long, deep belch. He moaned out in relief, exploring the expanse of his huge gut.
“Fuck, look at you. You’re huge, Katsuki.” Kirishima replaced Bakugou’s hands with his own, sensually rubbing his large hand all over his overstuffed belly. “Even bigger than before,” he expressed in amazement.
”Mmh, yeah. Feels so big. I’m– hic– so fuckin’ full.” His eyes fluttered shut, delighted at the warm hand soothing his stomach.
“Does it hurt?” Kirishima asked softly.
“A bit. Just– really tight. Need a second.”
They’re both quiet for a bit. Basking in the comfort of each other’s presence. The hand on his belly feels so good, and he can’t help the small satisfied noises that escape him.
Kirishima moved closer, his hand still rubbing soothing circles on his belly, but now their bodies were touching again. When Bakugou turned to face him again, Kirishima was already looking at him.
They were so close, and then the gap closed, and it just felt so right. Their lips met in a soft kiss and Kirishima could taste the faint sweetness left from the cake. Bakugou sighed contently, moving his lips against Kirishima’s own. When they pulled away, a shy grin broke onto Kirishima’s face. Bakugou couldn’t help but lean in again, capturing Kirishima’s mouth into a soft, but slightly more heated kiss.
Bakugou realized that Kirishima’s hand had stopped during this, so he slid his palm over the back of Kirishima’s knuckles and motioned for him to continue. Bakugou’s moan was muffled by Kirishima’s mouth when his hand started moving again, rubbing more energetically and grabbing whatever part of Bakugou’s belly that he could.
When they pulled away again, they were both panting heavily. Then, Kirishima leaned in again to kiss at his jaw. Bakugou shuddered at the sensation. Kirishima pulled him closer by the hip, his lips moving to whatever expanse of skin was exposed from his loose shirt to press open-mouthed kisses on his sensitive skin.
Bakugou whimpered and Kirishima pulled away, the hand on his belly slowed. “You still have your chocolate milk,” he reminded. Bakugou’s belly growled gluttonously.
Kirishima leaned back to grab the jug, uncapping it before bringing it to Bakugou’s lips. “You don’t have to finish it all. Just a bit to wash down the cake, yeah?”
He nodded, and Kirishima lifted the jug and watched the liquid spill down to his belly. He gulped loudly, his throat moving as he swallowed. He had both his hands on his stomach again, feeling the way the milk filled up every last crevice of his fattened up belly.
After a short while, he motioned for Kirishima to lift the jug away, to which he followed. He panted as Kirishima capped up the jug and took the plate off his lap to place them both on the bedside table. When he nestled back up again, he whispered words of praise and patted his tight belly.
Bakugou belched heartily, loud and unashamed. He then thumped a fist to his chest and let out another large burp. Kirishima cooed proudly.
“Such a good, stuffed belly. You did so amazing, baby.” Kirishima said, and the petname made Bakugou’s heart flutter. He moved Bakugou to lie down and sidled up right next to him, stroking soothing circles onto his belly.
Huge was an understatement, and Bakugou was close to falling into a food coma. Kirishima kneaded his belly, releasing pressure that rose out of the confines of his stomach as a relieved belch.
”Bet that felt good, huh?”
Bakugou nodded, teasingly patting his own belly. “Eijirou…”
”What is it?” he asked kindly.
”Stay?”
Kirishima grinned widely. “Of course.”
Bakugou, satisfied, closed his eyes and slowly fell into a deep sleep. Kirishima watched the rise and fall of his engorged belly, then fell asleep not long after.
