It never failed to amaze you.
Midoriya...
...Sweet, mild-mannered, timid, jittery Midoriya, could, somehow, pack it away more than the vast majority of both of your fellow classmates in 1A. Maybe his training or his Quirk had given him an accelerated appetite. But whatever it was, the green-haired boy could pack away enough to put a man twice his size to shame.
In contrast to the other big eaters of the class, Bakugou, Kirishima, Kaminari, and even Todoroki, Midoriya wasn’t boastful or overtly gluttonous. In fact, he was often very embarrassed about eating so much around other people. But when he was hungry, embarrassed though he tended to get, if he had to eat, then by God, Izuku Midoriya was going to EAT.
The two of you had just eaten dinner. You’d ordered takeout and, because you knew Midoriya was going to be working extra hard throughout the week, you decided to surprise him with a proverbial and literal feast. The look of awe and sheer gratitude on his young, freckled face made it all so worth it. But nothing more so than the sight of the green-haired boy stuffing his face so ravenously and hungrily.
You couldn’t explain it, but the sight of Midoriya gorging himself, and the sight of that normally rock-hard six pack of his rounding out never failed to rile you up. By the time the food was finished, the poor boy was stuffed beyond belief. He was dressed in his favorite All Might T-Shirt and workout shorts, and he was currently lying down on your bed, curled up and groaning miserably to himself.
“...Ohhhhhh, m-man, I really overdid it this time,” Midoriya whimpered, cradling his belly with both hands as he desperately ran his hands up and down his overly bloated stomach in a failed attempt to soothe the pain away. Normally, Midoriya’s trim, athletic stomach was perfectly concave. But after dinner, Midoriya’s belly had rounded out by two feet, pressing out considerably, hiking up his shirt enough to expose a fair bit of his bare belly, and pushing the waistband of his pants down, exposing some of his underbelly in the process.
“Poor baby,” you said in a sympathetic tone as you crawled into bed and nestled up behind Midoriya. From behind, you wrapped your arms around the boys’ torso, grabbing Midoriya’s big, round belly from behind and tenderly just held it in your grasp. It never failed to amaze you just how big and round Midoriya‘s stomach could truly get after such a hearty meal. Those normally firm abs were completely thinned out, as if they never existed. In his current, engorged state, Midoriya’s belly was unbelievably soft, sloshing heavily from all the contents within his gut digesting and burbling away, while your fingers caressed that burbling dome of his all over. His abdomen was perfectly smooth and round, flesh so soft that you could grab his belly and jostle it to your hearts content. It was strange how jiggle-y Midoriya’s belly got whenever he was this stuffed. You figured that if school and the occasional real-life catastrophes didn’t keep him and the others so active on a near-daily basis, Midoriya would be considerably softer at this rate.
...Though, you honestly wouldn’t have complained if he did get a little chubbier. After all, he was immensely cute no matter what he looked like. The fact that Midoriya looked so great with a belly was just a perk to you.
Slowly, you ran your hands all over Midoriya’s belly, grasping at his sides, slowly caressing upwards and kneading the upper crest of his stomach. And oh so slowly trailing down and kneading away at his underbelly. You knew Midoriya’s cheeks were probably burning bright red right now from all this physical contact. But in spite of his embarrassment and flustered state, a low, pleasant humming sound from the boy told you that your treatment was working. So you continued...
During your sensual, soothing ministrations, you felt Midoriya’s belly gurgle intensely beneath your palm, making the surface of his belly jostle just ever so slightly. Then, Midoriya brought a fist to his mouth and muffled a deep burp, just barely holding it back as it reverberated in his closed mouth. When it ended, Midoriya covered his mouth and muttered a sheepish, “...E-Excuse me, s-sorry about that...”
Grinning somewhat eagerly, from behind, you grabbed the front of Midoriya’s bulging belly, feeling it gurgle deeply beneath your palm. Then, you pressed into Midoriya’s big, soft tummy, causing your palm to sink slightly into his soft, bloated flesh. But it was also enough pressure to cause another pressure pocket to rush up Midoriya’s throat, and before the boy could try to stifle it, Midoriya let out a BIG, rumbling belch, one that erupted from the very depths of his stomach and carried on for a few seconds straight.
That was another thing you loved about the boy. Polite and sweet as he was, Midoriya could burp loud enough to wake the dead if he was full. Maybe that was why he always tried to hold them in if he could help it. But you didn’t want him to hold them in, not around you, at least.
When it ended, Midoriya’s eyes were wide as saucers as he clamped his hands over his mouth in horror. You just laughed and gave the side of his belly a few playful pats, making Midoriya’s belly jiggle some more with each pat, and causing the boy to hiccup and, in turn, blush even more. “Mmmm, I’ll bet that felt nice, huh,” you mused as your fingers continued exploring every inch of Midoriya’s supple, smooth stomach.
Midoriya didn’t respond. But the small huff of relief he let out shortly after told you all you needed to hear.
You eventually rolled Midoriya onto his back, causing his rounded belly to jut upwards, sloshing heartily in response. You scooted closer and closer, hugging one arm all around that ample, gurgling stomach of his, planting your palm against the dead center of his gut, causing it to jiggle beneath your palm and working up a cute little hiccup from the boy, making his belly jostle in response to the sudden jerk, and making Midoriya blush deeply.
God, he was so cute...
“...Man, you were REALLY hungry today, weren’t you,” you teased, poking Midoriya’s bulbous belly with your index finger, causing it to wobble a bit.
“W-Well, Kirishima suggested I try, um, b-bulking up, eating a lot and working out extra hard. I have to be in top shape when the next Internships begin. I can’t give any agency anything less than that,” Midoriya remarked, determined, to be certain, but clearly flustered by all the soothing treatment you were providing his belly. He was still not very used to all this contact. It was adorable, to be honest.
And his insistence on always pushing himself to work harder was nothing short of admirable. Sometimes, you genuinely envied his work ethic, and especially how modest the boy continued to be, no matter how much his skills improved. “You’ll do fine,” you assured the boy, caressing the dead center of his smooth, round stomach.
Your finger traced all around that adorable bellybutton of his, occasionally dipping your finger into Midoriya’s navel and making him croon. You could feel Midoriya’s entire body tense up whenever you played with his bellybutton. He was clearly into it, but so not used to, well, being into ANYTHING really, hence why his cheeks seemed to be burning up more and more as your treatment continued.
With your free hand, you reached around the waistband of Midoriya’s pants and carefully tugged his sports shorts down. Midoriya tensed up even more, making you chuckle with amusement. Fortunately, you weren’t looking to turn this into something smutty. You just wanted to expose more and more of Midoriya’s underbelly, to the point where the band of his All Might-themed boxers was now slightly visible.
You sat up a bit and grabbed Midoriya’s belly with both hands, gripping his tender underbelly and kneading into it with your thumbs. “Mmmm, what a big, beautiful belly you have, Midoriya,” you practically purred as you oh-so-slowly ran your hands all the way up Midoriya’s belly, to the point where your fingers were digging into his firm, athletic chest. Red as his cheeks were, Midoriya couldn’t help but moan pleasurably in response to the treatment you were giving him.
You continued caressing his smooth, soft underbelly, the area between his bellybutton and his pelvis, letting your thumb knead away into it. Then, you leaned your head down and planted a warm kiss around his underbelly, and then slowly yet steadily planted more and more kisses on Midoriya’s bulbous belly. When you reached his bellybutton, you were a little more bold, running your tongue around the outer rim of his navel, and then inserting your tongue into his deeper navel and licking it. Midoriya’s cheeks were flushed red, but he still bit his lower lip and moaned pleasurably in response to the treatment.
“Did you like that?” You asked in a low voice, resting your head against Midoriya’s round, pillow-y stomach. The boy just nodded shakily, unused to this sensation, but not at all opposed to it. Grinning, you slapped your hands against the side of Midoriya’s belly, making it jostle a great deal beneath your palm as you continued planting more and more kisses across Midoriya’s belly, until you eventually reached his chest.
Midoriya whimpered to himself. He was NOT used to any of this, and you could tell he was feeling really anxious, being the worry wart cinnamon bun that he was. But you were easier on him, keeping one hand firmly grasped around the dead center of that pooching belly of his, and planting a kiss across his adorable, freckled cheek, which burned red as a tomato after that. Midoriya truly was too cute for his own good sometimes.
But it seemed all that grasping and pressing you were doing to his belly was disrupting a lot of the pressure inside. Midoriya grimaced with discomfort, turning his head away from you and promptly burping into his fist. Grinning, you leaned in close and said, “Go on, cinnamon bun, let ‘em out...”
Midoriya was trying his best to stifle the pressure brewing in his gut, but he knew it wasn’t going to work. So, instead, he thumped his chest and freely let out a low, modest belch.
“BrrruuUUUUUuuuurrroooh-UuUUUuuUUrrrraaarrp!”
It was airy and shaky, yet there was some degree of mild heft behind it.
You grinned and shook your head. “Come on, you can do better than that,” you insisted, giving Midoriya’s belly a couple of firm pats, making it jostle and jiggle even more. All that patting dislodged another pressure pocket, making Midoriya grimace yet again with a look of deep discomfort on his face.
“BAAAAAAAAARRRRROOOOOOOHHHOOOOUUUUUUURRRP!!!”
The next belch was considerably louder, deeper and more forceful, carrying a good deal of power behind it. When it ended, Midoriya huffed and gasped to himself. “I think you got one more in there,” you insisted, then, you PUSHED Midoriya’s domed out belly firmly, causing your palm to sink slightly into his soft, almost squishy flesh. And like clockwork, Midoriya’s eyes bulged along with his cheeks as a massive pressure pocket rose up his throat and exploded from his mouth in the form of a HUGE, roaring belch...
“BEEEEEEEEEEEELLLUUUUUUUURRRRRRRR-OOOOOOOOOOOOORRRRRAAAAAAAAAAAP!!!!!!!”
It was a massive, wall-rattling burp, one that blasted out of Midoriya’s mouth with such force that his belly actually quivered beneath your palm in its wake. And it was so loud that your ears actually started ringing. But by God, you didn’t mind, because that magnificent eructation lasted for close to ten seconds straight!
When it finally ended, Midoriya was left gasping breathlessly. His big, round belly rose and fell as he desperately caught his breath. Midoriya eventually grabbed his belly with one hand and brought his other hand around his mouth, looking groggy but deeply relieved. “Ohhh, oh man...” Midoriya huffed and puffed, cheeks reddened, but facial expression conveying not embarrassment but sheer, blissful relief. “Ohhh, oh wow, that felt good,” Midoriya cooed, patting his stomach contently as it jostled beneath his palm.
The pat seemed to disrupt something, making Midoriya crack his mouth open and let out one last burp out from the corner of his mouth.
“EEEEEEEUUUUUUUURRRRrrrrrhp!!”
You just laid there besides him, all smiles, and feeling your own cheeks darken.
...This was going to be a very, VERY good week...
