Summary
     - He'd just wanted a do-over of his end-of-term exam.

     A chance to prove he wasn't dead weight; that he didn't need to be
     rescued by anyone, let alone Deku of all people—being carried,
     unconscious, through the gates after he'd decided to sacrifice
     himself to win… no. Katsuki could not stand to see that. Being
     humiliated like that.

     Not in front of All Might.-
Notes
     You can judge me.
     I'M judging myself.
      
      
     but also kinda patting myself on the back for this. lol

He'd just wanted a do-over of his end-of-term exam.
A chance to prove he wasn't dead weight; that he didn't need to be rescued by
anyone, let alone Deku of all people—being carried, unconscious, through the
gates after he'd decided to sacrifice himself to win… no. Katsuki could not
stand to see that. Being humiliated like that.
Not in front of All Might.
The same All Might who was looking at him from across the coffee table in the
teachers' lounge, a clearly disillusioned downward curve to his mouth and his
normally blue eyes cast in shadows as the setting sun streamed into the room.
Katsuki could hear the words before they even made it out of the man.
«I am quite disappointed in you, young Bakugou,» All Might said, sighing.
«After such a commendable effort in collaborating with young Midoriya
yesterday, I had believed you might have glimpsed the right path...»
Katsuki bristled, his frown deepening: there was nothing good about having his
heroic moment kicked to the side by fucking Deku, not after how much it cost
him to swallow his pride and work with the pathetic asshole who was too into
his hero worship to even be willing to fight back against the Number One hero!
What right path, he scoffed mentally, fuck that!
Katsuki let a sneer twist his lips, ready to voice his thoughts, when All Might
interrupted him. «It seems an extra lesson is needed, young Bakugou,» he sighed
a second time, eyes closed in resignation. «Maybe this time it will get through
your thick skull.»
As soon as the man finished speaking, he acted. Katsuki barely registered a
foot being planted on the low table, before he found himself flying over it and
pinned to the backrest of the couch. Eyes blinking at the sunset-orange-tinted
wall, he fought back the sense of nausea twisting his stomach at the lighting-
fast movement. His bearings back under control, Katsuki made to turn around and
yell profanities in All Might's direction, disrespect be damned—
A hand came up to his nape, freezing him in place.
He could smell the green tea in All Might's breath when the man leaned down,
ear-level with him. «You are so obsessed about being at the top, young Bakugou-
» his voice as dangerous as it'd been the day before- «you do not seem to
realize you are still at the very bottom of a very tall ladder.»
The power exuded in the mere loose grip of the hero's hand around his neck; the
memory of the menacing look All Might had pierced him with during the practical
exam—the same he was no doubt wearing now—; the not-so-gentle way in which the
hero let his massive chest press down on Katsuki's back, trapping him between
that muscled body and the piece of furniture, his ribs digging into the
cushions.
Katsuki shivered, eyes wide, his heart picking up its pace. «Get the fuck off
me, All Might!»
The Number One hero hummed. «That is no good, young Bakugou.»
The man's free hand came down on Katsuki's ass, swift and harsh and heavy. A
gasp escaped him, the sting of the hit felt through his clothes, aftershocks
spreading along his nerve-endings like fire.
«What the fuck All Mi—ggh!» A second slap cut him off, a third one following
immediately after.
«You need to learn respect for others,» All Might said. «You will never be a
good hero, otherwise.»
Katsuki growled, pushing back against the hold on his nape; he planted his
hands on the backrest, palms smoking, and tried to heave himself up. It was no
use, of course. Katsuki was one of the strongest in class, but he was aware he
had no chance of lifting 255 kg of an oaf who had no intention of moving off of
him.
«Fucki—ngh! » A fourth hit, stronger than the others, left a more lasting
sting. The force of it squashing his hips to the couch, the tingle coupled with
the abrupt friction against his crotch making Katsuki realize he was hard.
Shiiit! he thought dismayed. «I don't need some goddamn lecture on—»
His school uniform's slacks were ripped off, belt and underwear going with
them, pooling in shreds around his knees.
«What the shit're ya doin' All Might?!» Katsuki shrieked, trying again to slip
away from the man's clutches, to no avail.
To add insult to injury, he was ignored and another merciless spank struck his
now-bare ass, the blow much more painful than the ones before.
Katsuki's toes curled in his shoes, balled-up fists crackling as sparks
ignited. He moaned despite himself, the sound echoing loud in the otherwise
silent room, and his face flushed dark. Behind him, Katsuki heard a noise
coming from All Might—a choked sound, as if his spit had gone down the wrong
pipe.
A shudder ran up his spine at the possibility of his childhood hero finding his
moaning exciting.
Katsuki's cock twitched between his legs; he rutted on the leather couch to
relieve some tension, groaning and smearing pre-cum over it. His hands itched
to touch himself as All Might spanked him. As All Might kept him still with his
large hand on his nape. As the Top Hero spread him open and relentlessly
pounded his ass with his cock—a huge thing probably, impossible to wrap in only
one hand, impossible to swallow whole—the same way he'd done with his fists in
his fight against that Nomu.
Shit what's WRONG with me…?! he questioned himself, catching a garbled, needy
call for the Number One hero to do just that which almost made it past
Katsuki's throat.
Rustling of fabric reached his ears over his pants, then he was sandwiched
between the cushions and the vast expanse of All Might's torso again.
«Did you learn your lesson, young Bakugou?» he asked, all gravel and dominance
in his voice and Katsuki thanked God he was already on his knees, because he
would've fallen upon them before his idol anyway. «Or do I need to punish you
further…?»
All Might rolled his hips upward and all air left Katsuki's lungs in a drawn
out whine he'd definitely be ashamed of in any other situation. Something rock
hard, hot, massive poked him. It rubbed along his balls and the underside of
his own straining erection. Katsuki felt lightheaded, on the verge of blowing
his load just from such a small contact.
He couldn't believe he was getting off on this… yet, the prospect of it ending…
Katsuki was doubled over the couch, half naked and more worked up than he'd
ever been in his life; he was humiliatingly vulnerable under All Might's hands,
and his brain was shutting down, processing nothing—nothing but the craving to
have his hole fucked raw by his idol.
Heart thundering in his rib-cage and ears, Katsuki ground his hips down to rut
on his teacher's cock. «I-I don't—fuck teamwork, All Might-» Katsuki swallowed
through a dry throat- «Don't need fucking D-Deku to win…!»
All Might said nothing in response.
The hand he'd had skimming Katsuki's stomach left and returned promptly to
smack over his right ass-cheek, the man's hips snapped up and forward at the
same time, lifting Katsuki off the cushions.Goddamn— His eyes rolled to the
back of his head, body sizing up, cumming untouched with a wild moan, the sound
covered by the loud pops of explosions as Katsuki lost control on his quirk.
A second later, he was flipped around with monstrous ease, mind still fuzzy
from his orgasm, limbs loose like jello. His chin was snatched in a commanding
grasp, his jaw pried open as far as it could go and the fat, blood-red head of
All Might's cock was shoved passed his teeth. Katsuki's air supply was suddenly
cut short, his eyes snapping wide in fear mixed with a delirious hunger.
«All… ght-M-Might…!» It was a distorted call, a jumbled mess of sounds and spit
dripping down his chin, his tongue trapped under the hefty girth of his idol's
cock.
The man's left hand gripped Katsuki's turfs of hair, guiding himself in and out
of his wet, sloppy mouth, and Katsuki sucked on it in earnest, coating every
thick inch in saliva. The strong musky scent of sweat and the bitter taste of
pre-cum milking shameless groans, over and over, the vibrations surely reaching
All Might. It was a heady sensation, being used like this by the Number One
hero, someone he'd always look up to.
Intoxicating, addicting.
«You want me to continue this, do you not, young Bakugou?» said All Might, too
calmly for Katsuki's tastes, and staring down at him with a predatory look in
his bright blue eyes. Almost a challenge.
Katsuki didn't know if the teacher had forgotten he was supposed to be
punishing him, but at that point he couldn't care less. As soon as the man
freed his cock from his abused mouth, he didn't even waste time for his
breathing to normalize to answer.
«Fuck me,» Katsuki challenged right back.
He snatched the huge length before him in both his hands, moaning as he
realized he'd been right: one hand wasn't enough for that thickness. «Fuck me
hard, fast—wanna feel it for the next two weeks-» he flattened his tongue over
the straining head, lapped up a pearl of pre-cum, whined; repeated the process
twice more- «whe'ever I sit, I move, I fight—whe'ever I see Deku—wanna feel the
phantom sensation of your cock pulsin' in my ass.»
He sounded like a bitch in heat. He mewled at the thought.
«Such a filthy mouth,» All Might growled. His expression morphed into something
aberrant, sinful. «Turn around, young Bakugou.»
A shiver of carnal thrill rushing in Katsuki's veins at the man's reaction, he
climbed back up and did as told. He was in the same position as before, bare,
inviting ass now more than willingly pushed outward. Katsuki spread his own
cheeks wide, his hole clenching with a yearning desire to be filled.
He wondered if the hero was going to stretch him out; he'd need it for sure,
especially with that massive length, yet part of him wished he could take it
without.
Katsuki's own cock, which had come back to full hardness while he gave All
Might head, was already oozing pre-cum for a second time. He groaned, unable to
stop his hand from fisting his leaking erection and pumping it quickly a couple
of times, desperate and impatient. He didn't even care about the danger of
accidentally setting off an explosion, rather, the risk made his blood flow
even faster and Katsuki was spilling all over the leather couch again before he
knew it.
«Hurry up and... ram into me... All Might,» he prompted, voice croaky and
trembling, his whole body quivering alongside it in the wake of the climax's
high.
«What a bad boy, so selfish, taking care of yourself first,» the man said,
voice husky and vaguely amused. «If you want to become number one-» Katsuki
inhaled sharply at the feeling of slick, wet, thick fingers circling his hole-
«You have to work on your manners, young Bakugou...»
Katsuki rocked his ass backward on the digits poised, un-moving, at his
entrance, silently hoping it'd be enough for them to breach through. He grit
his teeth in frustration when All Might retreated his hand, tutting.
Fucking fine.
«Pl-please All Might!» he begged, face so red he was beginning to lose any
feeling in it. «Please fuck me! Please please!! I wanna feel my stomach bulge
on your fat, fat cock All Might—please!»
It was liberating, begging like that, and it came to him so easilyin front of
that man.
Katsuki chanted «please» while the Number One hero demanded he keep his hands
planted on the couch, forbidding him from touching himself. He gasped it as
large hands groped his ass, spreading his cheeks open and slicking his rim with
cold lube. Wheezed it, interrupted by a lewd moan, when All Might's fingers
finally sunk inside him. Katsuki's voice turning wobbly with the sting of two,
three, meaty digits scissoring him; raising into a strangled slur the moment
his third, dry, orgasm hit just from the feeling of his asshole pulled taut.
«Relax, young Bakugou,» All Might warned, voice gruff, pulling his fingers out.
«I am... quite... big.»
Katsuki keened at that, still shivering and pliant and trying to regain his
bearings.
His nose was assaulted by the acrid smell of burning leather and nitroglycerin,
a chain of continuous small-to-medium sized explosions destroying the couch
splinter by splinter. If he'd been with anyone else, Katsuki might have been
terrified, but he wasn't. He was with All Might and for that reason, when the
man's cock head pushed past his rim and another loud discharge blew away the
left side of the piece of furniture, Katsuki merely sobbed and wailed a «FUCK
ME ALL MIGHT!!» at the top of his lungs.
«So... tight...» was all the hero choked out, gripping Katsuki's hips in a vise
and diving deeper into his heat. «I'll move, young Bakugou.»
«YES! Yes yes!» Katsuki braced himself and shoved his ass backward, effectively
impaling himself on that hard, hulking cock, stretching him beyond the point of
tolerance.
The slow drag of All Might pulling back kicked Katsuki's heart into overdrive
because of the burn and anticipation. The first earnest thrust forward—most of
the man's weight and bulk into it—lifted Katsuki's knees off the cushions and
ripped a indecent cry from deep in his throat, All Might's name falling from
slack lips even as Katsuki felt the skin of his hole tear. Katsuki dug his
nails into what was left of the couch and by the third harsh jab at his
insides, he had no further support; at that point only his teacher's hands
sustained his weight, and Katsuki was left half crouched, doubled over himself
with his head around his knees.
The new position allowing the cock stuffing him to assault Katsuki's prostate
with inhuman precision at each thrust. He'd long since lost count of how many
times he'd cummed; dry or not, he had no idea.
He just couldn't stop moaning, trembling.
His body writhed and arched, jolting under the onslaught of electrifying
sensations. Katsuki's vision going blurry as tears of pleasure and pain and
satisfaction drenched his heated, gross face, slick with snot and drool as
well. Every «pleasepleasemore!» and «Ican'tanymore!» and «harder!» rasping in
his throat like sandpaper; his voice was utterly ruined, brittle and barely
above a whisper; hoarse keens robbing him of what little oxygen he found
between the savage thrusts bending him in half. His brain was mush, he didn't
know anything anymore, could not feel anything that wasn't the fat cock plowing
his ass so hard he'd probably need Recovery Girl—and how would Katsuki explain
that huh? And why did that thought make him beg to be ripped in two that much
more desperately?
«I-I'm— close, young Bakugou…!» All Might grunted, breath short. The bruising
grip on Katsuki's body weakening a little, his hips inching backward.
Katsuki's eyes flew wide in realization the man planned to pull out to cum.
«NO!!» he shouted, clenching around the twitching cock inside him as hard as he
could, even aiding himself with his smoking hands to push his ass cheeks
together. «INSIDE!! Pleasepleaseplease—want it…!!» He sobbed and begged,
thinking of the shit-load of Top Hero spunk about to be dumped inside him,
about to mark him into complete submission.
«Fuck, young Bakugou-» All Might tightened his hands at Katsuki's sides once
more and shoved the whole length of his cock into that loose, gaping, bloodied
passage- «Fine then, just… take it all!» All Might roared as he spilled a
torrent of scorching cum, painting Katsuki's guts with it.
Katsuki's eyes rolled back into his skull with one last mute cry, his world
going black, fainting in All Might's hold completely blissed out and spent.
End Notes
     Douse me in gasoline and set me on fire - is what I've been repeating
     for the last 36 hours, during and after writing this hot mess of
     filth...
     I should've stayed far FAR away from that kink meme, but I didn't and
     now I'm here. A hardcore bkdk shipper writing more about those two
     banging someone other than each other. WTF. （￣□￣；）
