Summary
     Izuku and Katsuki undergo some kind of punishment.
Notes
     it is january 1st, 3:49am. i am sitting upon my couch as the soulful
     voice of the weather girls blares in my living room.
     all this shit was dished out in the comfy leather sofa of my friend's
     humble abode, as i watched my beloved friends and my newfound friends
     chat amongst each other in the gentle ambience of the upcoming year.
     i, a slow writer, am a damn fool for thinking i could finish this at
     the asscrack of 2017- i ended 2017 writing this and i spent my first
     few hours of 2018 editing it.
     the details in which these boys get their asses whooped by the big
     buff banana man came too fluidly and fast to be healthy or decent
     enough to read, please take this from my sad hands. happy new years,
     everyone.
See the end of the work for more notes
"5%."

Even at such a small percentage, Izuku feels his knees buckle in with the firm
slap on his ass. He's kept his sounds to himself, hunched over a desk. Katsuki
is in a similar position on the desk next to him, only differences are that
Katsuki’s still got his pants on and he gets the privilege (or perhaps not,
considering just how disgustingly hard Izuku's getting from finally getting
attention) of being able to wait. Izuku doesn't bother looking over, he already
knows Katsuki's burning red eyes is glaring into the back of his mind. Even
now, Izuku was being put above him yet again-

"You think you can get away with this?" All Might booms, his gigantic hand
spreading the already reddening flesh. "You aren't even half the hero I trained
you to be."

"A-A-All Might, I-"

"10%."

Izuku cries out this time, the sound coming out too lewd and too hurt, but god
does he want more of the thrill coming from this. He can't even remember what
he was about to say, his brain could only focus on the sharp pain dispersing on
his bottom, on All Might's tremendous form leaning all his pressure on his
smaller body. He chastises himself for already being incredibly weak at the
knees with the second spank, but could he be blamed? This is All Might, of all
people. Just two spanks and Izuku's trembling like a madman, tears already
stinging the corners of his eyes.

"Fuckin' shit, Deku." Katsuki mutters, but Izuku's too wrapped up to notice
whether it's out of hatred or utter shock.

"Don't. Even speak, Bakugou." Now that tone, Izuku can pinpoint clear as day,
he knows what being scolded is like- this wasn't it, it's too sharp, it's the
only thing that could make Kacchan of all people shut up in an instant, it's
beyond that. It's pure, unbridled anger and just for a moment Izuku forgets
he's under his childhood idol, only feeling a burst of fear when the bigger man
leans close, his breath looming over the back of his ear. "Ha, you're shaking
now? You don't even know how your dear friend Katsuki will end up."

At that, Izuku lets out a soft moan, cut off by a sound of disgust by the boy
next to him and the stern voice calling out a "15%."

Izuku hears it, but All Might's stopped, only rubbing the mound of flesh that
he's sure he's left a mark on. He almost wants to ask, "What's taking so long?"
but his line of thought comes to a halt with the now-excruciating strike of All
Might's palm.

Now, Izuku's borderline whining, his legs shifting as they try to stay in
place, he knows damn well he won't be able to sit for at least a couple days.
The tears are coming in steady drops, and the familiarity of the wet feeling
rolls down his cheeks. It hurts like hell, but in the best way possible, and
the teen only feels guilt wash over him when it clicks that he's feeling this
way over his ultimate role model. With the stinging feeling dispersing
throughout his entire lower half, he lets out a whimper, " P-please, stop- "

"Why would you want me to stop? Isn't this what you wanted? To get me like
this? "

Izuku assumes that this means the raw anger, the blistering way that All
Might's voice booms in his and Katsuki's ears, but he couldn't be anymore
wrong- All Might leans over Izuku again, but this time, Izuku can only feel the
enormous bulge against his bare ass. For a moment, all he can think is I want
this, I want him, I want it all as another helpless whine escapes his throat.
He hears a shaky huff against the desk next to him, wondering what the
proclaimed #1 student's feeling, is he watching? Izuku can only wonder what
this looks like- his childhood hero grinding hard against his ass, bent over a
damn desk wanting to be punished; he'd laugh if his mind wasn't diluting itself
with every thought of anticipation. If Kacchan's really watching, maybe he
could see Izuku's every guilty thought of All Might- big and proud and
everything I want to be-

"20%."

There's no pause this time, just a step back and another quick, nerve wracking
strike that doesn't compare to the rest. It's sharp and layering itself on top
of the pain left behind by the other spanks, the harsh feeling makes Izuku's
nerves heighten, makes his soft rolling tears turn to pathetic sounding sobs.
He feels just how messy he probably looks- if his tears are as big as they feel
when they roll down his face, then the hardwood below him should be flooded,
his curly green hair should be sticking to his face, his eyes should be too
damn red and his cheeks should be too damn wet, and he should feel ashamed but
only feels a sick sense of desire in his gut. He should feel guilty, disgusted,
utterly repulsed for even thinking of going through with such a plan, but all
he can hear is All Might's voice repeating "Isn't this what you wanted?" He
feels All Might's palm on his ass again, not abrasive and not hostile, just
spreading until he's wide and exposed, and a dark part of his brain thinks, I
hope Kacchan's watching all of this.

Kacchan must be, he hasn’t said anything or even made a single noise on the
desk next to him, just soft breaths that could only be heard if Izuku really
tried; frankly, he isn’t in the mind to. He’s too busy quivering, melting under
the firm touch of his precious hero with the feeling that he’s only getting
spread thinner and thinner, there’s only so much room in his head to spare for
his childhood friend, and even then every lingering thought is much too dirty,
too selfish to bring up. It isn’t until All Might speaks up again that Izuku’s
pulled out of his own head and brought back to the reality of it all.
“You think you could take advantage of me like this?” All Might chides, “Oh, my
boy , you are more selfish than you think. I train you, I take you under my
wing so you can rise above me someday- but now I have to treat you like a
goddamn child because of how selfish you are. Heroes aren’t selfish , they
don’t ask for any more in return- they don’t ask for this.”
It takes too much of Izuku to hold himself back. Through all the stinging in
his rear and all the tears pooled up under his face, he’s still painfully aware
of how overcome with lust he is and how hard he is pressed up against the desk
like some low budget pornstar. He knows it’s vile that all he can think to say
is yes, yes I’m so selfish but I want to be yours,and that all he wants to hear
is just that same kind of conviction from his role model- just the same kind of
language to drag him down until he’s faced with his flaws and emotionally beat
up until he’s left tender.
“25%.”
“F-fuck,” Izuku cries out the swear, too foreign coming out of his own mouth
but he’d be damned if the word doesn’t sum up everything he wants, and he
squirms as All Might’s flat hand stays along the stinging mound of flesh. His
legs are just about ready to give in, but Izuku focuses on every last bit of
strength he has left once he feels the heftiness of All Might’s fingers creep
closer and closer and closerto where Izuku wants them to be, until it’s gone.
The ghosted feeling leaves him hiccuping out a “More,” without a second
thought, but the air becomes still again-
“30%.”
The cry that rips through Izuku’s throat and the classroom is still ringing in
his ears, everything’s coming too quick and he swears he starts seeing stars.
He feels his entire body ripple under the powerful strike of All Might’s hand,
not even being given a break or a soothing pat on the ass- how much more until
I break?- and his cries get muffled by something intruding his mouth. It’s
thick, rounded but rough, i-is it...his hand?
“It seems you need a lesson on volume control too, don’t you? Don’t forget,
we’re in class.”
It doesn’t even take another spank for Izuku to crumble, the only thing keeping
him up now is All Might’s looming strength- he’s hooked by the mouth, with All
Might’s body behind him acting as an oversized human pillar. Without it all,
he’d drop to the floor in an instant, it’s all so much. One move of his leg and
he feels that giant bulge against his rear, and he slips a moan out around the
fingers in his mouth. If he thought he looked tragic before, he must’ve looked
like a hot mess now, drool dribbling out of his lips and down his chin. The
fingers in his mouth are so big, stuffing him full with just a few digits, and
his tongue swirls sloppily as he tries to get as much of it as possible. He
shifts his hips in attempts to get a stronger feel of the package too close to
his ass, and for once he almost wants to hear the nasty things that Kacchan’s
most likely itching to scream at him, even if they both know they’ve got the
same interests in mind. “You’re a fucking slut, Deku, a dirty fucking slut,”
rings too loud in his head- he knows too well it’s all so dirty , he shouldn’t
be trying to fuck his favorite hero and a teacher, at that, but there’s no room
for guilt when the monster cock he’s dreamed about since he was twelve is
grinding right against his hole.
“Young Midoriya, you better watch yourself.” All Might growls in his ear, he
growls,and his voice is laced with every rough emotion from pure frustration to
pure desire. He pulls away, leaving Izuku cold, empty, and limp on the desk,
and he rasps out, “Perhaps you haven’t learned anything after all. Maybe seeing
young Bakugou will change your mind.”
“N-no, All Might, please,” Izuku croaks, throat dry and voice shaky, as he
wobbles to keep himself up by latching onto the desk for dear life.
“Shut up and turn around. I don’t want to hear another word from you until I
say so.”
To the best of his ability, Izuku complies, only letting a few hiccups slip
through his quivering lips as he tries to lift himself up. His hands grip onto
the edge of the desk, his legs have gone weak in the knees and with every
stinging feeling in his rear he feels himself lose more and more strength, but
he lifts himself and turns around despite all the pain wracking his body.
Fingers digging into the hardwood of the desk, he watches as All Might takes a
step towards the blond bent over the other desk. He huffs, trying to regain
composure after all that had happened, but if All Might’s really living up to
his word, then Izuku knows that there’s only so much sanity left for the both
of them to cling to.
“On your knees, Bakugou.”
Izuku’s shaking as he leans on the desk for support, but he has enough sense to
be stunned at how fast Katsuki scrambles to the floor. Or at the very least,
complies almost immediately without biting back. He watches Katsuki crawl down
from the desk with knees spread slightly. He’s still in his full uniform, while
Izuku’s just barely got his uniform shirt on, and only the heavens know where
All Might’s thrown the rest of his uniform.
“Oi. I don’t want that counting bullshit, you know what we’re here for, I’m not
gonna-”
Slap.
Izuku recoils at the sound, eyes blown wide as he watches Katsuki take a harsh
slap to the face. If the power behind it was anything like the ones on his ass,
he could only imagine how bruised Katsuki’s face would be in the morning.
“You were saying?” All Might says, all seven feet of him looming over the much
smaller teen. His hand lingers in the air, palm flat as Katsuki’s head is
whipped to the side.
Katsuki slowly brings his head back around, staring straight up at the man
before him as he scoffs, “What, are you expecting me to cry like that fuckin’
nerd over there?” He nudges his head towards Izuku, face already reddening at
the sheer power of All Might’s hand. Despite his words, Izuku can spot how
Katsuki’s eyes are already glossed over, I wonder if it stings just as much-
Slap.
Katsuki bites his lip this time as he takes the second hit, once again slowly
turning his head back. There’s the slightest hint of tears in the corners of
his eyes now, but he rolls his eyes regardless. He huffs angrily, staring hard
at the ground and eyes trailing up to All Might’s shoes.
Izuku’s mouth is agape once All Might leans down low, harshly grabbing Katsuki
by the shirt collar with his foot slowly creeping between Katsuki’s legs, but
his mouth nearly hits the floor when he watches how the man’s shoe creeps
higher and higher until it’s lightly stepping on Katsuki’s crotch.
“Bakugou...my boy, you know I care about you. But frankly, your attitude is
proving to be too much.” All Might’s leaned in real close, eyebrows furrowed
and face centimeters away from Katsuki’s, “No decent hero is so conceited and
thinks so highly of themselves. You should know better.”
Katsuki lets out only a small groan then grits his teeth, the sounds feeling
like music to Izuku’s ears, as the loafer between his legs presses down harder.
Izuku can’t tell how much pressure All Might’s using, only feeling the hardon
between his legs grow when he sees Katsuki visibly gulp down hard with the heel
on his cock shifting back and forth. Oh no, why.
“Well, don’t waste any more of my time. Pants off, young Bakugou.” All Might
lets go with a subtle push and steps back, as Katsuki gasps once the pressure
on his cock is relieved.
For a moment, Izuku thinks the tension in the atmosphere shifts once All Might
pulls away and smooths out his dress shirt, but there’s still an angry wrinkle
between his brows and his muscles still look unbelievably tense. Katsuki’s
silent now, with his own eyebrows furrowed as they usually are, but it’s
different. He’s biting down hard on his bottom lip, so hard that it might
actually draw blood, as his hands trail down to the waistband of his pants that
already hang low around his legs. I’ve never seen Kacchan so reserved, why is
it so...
“Get on with it. You’re always so quick to do things but suddenly you want to
test my patience?”
Then, within seconds, Katsuki’s wrangled the pants off of him in a few shaky
motions, still visibly fuming, and he throws them off to the side, muttering,
“There. Now what?”
“On the desk.” All Might crosses his arms, Izuku watching All Might’s gaze
follow the half naked blond slowly bending over the flat surface.
“What, and Deku gets to fuckin’ stand and watch?” Katsuki snarks, adjusting
himself as his own arms are crossed over on the desk.
“He’s selfish, but he isn’t an arrogant little brat.” The man bites back,
rubbing his hands together for a moment, “At this rate, you might as well
consider following Endeavor’s path. Too conceited to ever be first.”
Even Izuku knows how low that blow was, watching (and admittedly getting
somewhat of a kick) at how Katsuki visibly winces, like he’s so close to
blowing up but refusing too. He stands, bent over, head now facing down into
his arms as the tension becomes so thick Izuku could touch it.
Slap.
Despite all the power Izuku knows All Might has, it’s something to consider
that the man follows through with Katsuki’s no-counting request. Maybe All
Might’s getting something outta it, too. It sounds...louder than he did it on
me.
“F-Fuck,” Katsuki hisses, the sound muffled from being head down on the desk,
until All Might strikes again, the sound being the loudest thing in the
classroom. “Holy fuck.”
The sight is too much for Izuku to handle, he can feel himself getting harder
with every sharp movement on Katsuki’s ass, he almost feels guilty but he
thinks that maybe, just maybe he could relieve some of the tension building up
in his gut if he just-
“Watch your mouth. And Midoriya, put your hands away.”  
Izuku flinches immediately, straightening up his posture to the best of his
ability and putting his hand back on the desk where it was. He follows the
man’s orders, but it doesn’t stop him from shifting his shaking legs for at
least some kind of friction.
With another unpredictably striking slap, Izuku inhales deep as Katsuki finally
brings his head up- his face is bright red as he lets out a guttural moan,
tears slowly streaming down his face. Izuku can tell he’s trying to keep them
in, and he wishes he was in the place to speak so he could mutter out a “C’mon,
Kacchan, just let it out,”but he settles for biting his lip instead, taking in
as much of the sight as possible. Katsuki chokes back any other sound, as All
Might rubs at the mounds of flesh until he gives them a harsh squeeze.
“What’s wrong, the proclaimed number one finally getting off his high horse?”
All Might says, before giving another sharp, seemingly harder slap,eliciting a
stifled cry from the boy under him.
“S-Shit...All Might-”
All Might grabs the smaller blond by his spiked hair and pulls back, and Izuku
watches as Katsuki arches back with the man’s movements, “No. You call me sir.”
“...Sir,” Katsuki chokes out, eyebrow twitching, and the array of emotions in
the room sends Izuku’s brain in a heated daze, “Fuck- sir, please, more,”
All Might scoffs, until the sound sounds somewhat of a cruel chuckle, “More? I
don’t think you deserve more of anything but discipline, my boy. At least not
until you get an attitude check.”
Then, almost ruthlessly, All Might continuously strikes Katsuki’s rear,
switching between cheeks until Katsuki has no choice but to finally crack and
let go, his stifled noises becoming clearer and clearer. Izuku stares with
bright eyes as he watches his childhood friend and rival crack below his idol,
breathing heavy at just the mere sight of Katsuki with tears streaming smoothly
down his face. He wishes that this wasn’t everything he’s dreamed about and
more, but it is, and the unattended cock between his legs only throbs with
every sound of each stinging slap filling the room. All Might pauses after, so
only Katsuki’s heavy, ragged breathing is what fills the room, and he steps
back again. There’s bright scarlet handprints on the creaminess of Katsuki’s
clear skin, and Izuku’s mouth waters (with shame, that he sets aside for
another day of contemplation,) as Katsuki’s tears hit the hardwood of the desk.
All Might claps his hands together then rubs them as if to clean off dirt that
was on them.
“That’s better. Both of you, get down here.”
Immediately, both boys shift to make their way to the man in the middle of the
room, but they both struggle with how weak in the legs they’ve become. Izuku
drops to his knees immediately and has to crawl, while Katsuki slowly climbs
off the desk and uses the desk to ease himself off. When Izuku’s settled and
glances over, Katsuki has the familiar look of reddened eyes and tearstruck
cheeks, masked with downturned eyebrows, warm crimson eyes burning holes into
the floor with how hard he’s staring off into the space. All Might stands in
front and in the middle, casting a shadow over the smaller boys. They look up
immediately, still wobbly from the last few moments, at the sound of All Might
fumbling with his pants, the clink of his belt buckle only building up the
anticipation in both of the boys’ parched throats. The man huffs as he pulls
the zipper down on the golden yellow of his pants, the bulge looking so much
bigger than it felt against me, oh god-
The moment’s still, until All Might puts his hands on his hips, letting out an
almost mockingly sounding laugh, “Well? Isn’t this what you two wanted? I think
I’ve beaten the lesson into you by now.”
Almost telepathically, the two boys turn to look at each other, and then back
at the raging bulge before them. Izuku’s lip quivers as he moves his head
forward, before Katsuki subtly shoves him to the side to begin mouthing at it.
Following Katsuki’s moves, the green haired boy moves in to mouth at the
opposite side- there’s enough room for both of us?- and he feels the thin
fabric absorb every self indulgent move from the both of them, occasionally
feeling their lips collide as they both lick at the thinly veiled cock. All
Izuku can think with every accidental liplock is I want both of them, but he
sets the thought aside once another minute passes and All Might nudges the boys
off. He slides a hand under, pulling the cock out from its confines.
“Holy shit.” Izuku hears from next to him, and he’d be damned if he didn’t
agree. ”Holy shit.” is right, it’s enormous , at least as big as Izuku’s
forearm- maybe even bigger,  and he licks his lips in desire as All Might’s
blue eyed gaze burns on the two of them.
Without a moment to spare, the both of them open their mouths and lap at as
much of the thick length as they can, and Izuku feels his face turn into a wet
mess all over again. Saliva spreads along his role model’s cock and all over
the lower half of his face, and he glances over to see Katsuki in the same
feverish state. It’s no surprise that Katsuki’s treating this like a
competition, with how he tries taking in as much of All Might as possible,
tongue messily swirling around. He starts low, tongue against the base and
hungrily moving up and up as Izuku stays at the very tip, lightly bobbing up
trying to take in the head.
“Good...you’re doing so good.” All Might shakily breathes out, placing firm
hands behind the heads of the two boys. It’s nothing like he was before, the
hands on their heads widespread in their hair instead of aggressive and tense.
As Katsuki makes his way up to the head, he faces Izuku, and their lips mash
together with the head of All Might’s cock inbetween it all. Izuku feels the
smaller blond rush his hand towards his cock, and he moans against the wet
heat. His hands tremble as he reaches for Katsuki’s length, fumbling with the
zipper then shakily moving his hand up and down as their mouths messily
collide. The feeling in his gut builds, until he realizes his eyes screw shut
and he’s panting with his tongue out.
“O-Oh god.” The green haired teen pulls away and gasps, as Katsuki follows suit
with short, heated grunts, then responding with a breathy, rough, “Shut up, I’m
close.”
They both look up, to see All Might’s features have softened, his eyebrows are
still furrowed but he’s breathing raggedly. The grip in their hair tightens,
and Izuku knows that it won’t be long until All Might releases too. Does he not
want to admit it?
“F-Faster.” Katsuki interrupts Izuku’s thoughts, and Izuku complies as he feels
Katsuki’s calloused grip become harsher against his own cock.
It isn’t long until Katsuki whips his head back and groans, hot white painting
Izuku’s scarred hands, and Izuku takes only a few moments until he’s the same,
seeing white as he rolls his hips into his longtime frenemy’s grip.
“Keep going, I’m not done with you boys.” All Might beckons, keeping their
heads in place as they slowly come off of their climax, and they lap away at
the sensitive tip as the man strokes.
The atmosphere shifts again as All Might begins to tremble, his legs shaking as
he strokes himself faster and staring down the two boys. With shaky breaths and
one sharp inhale, he stays as composed as he can before snapping his wrist
down, large, wet streams of white covering the boys’ mouths until it’s milked
out in smaller spurts. They’re nearly drenched, too much white spilling out
both their mouths, Izuku’s eager to swallow it all and is pleasantly surprised
to see Katsuki do the same. It drips on Izuku’s shirt, some of it shamefully
drops to the floor, but any single drop on their faces is immediately licked
up. Izuku watches intently as Katsuki licks all around his mouth, all until
there isn’t any white left on his face, and he already knows it’s a sight he
won’t ever forget. His head turns when he sees All Might take in a deep breath,
and like a switch, his role model beams that same old smile, as if the last
events weren’t spent reaming the two teens for every downfall in their
personalities.
“Ah, okay, you kids better get moving. Did you...learn anything at all from
this?”
Katsuki nearly laughs before he stops himself, wipes his mouth with his collar,
and only snorts out a, “Well fuck, I mean, I guess.”
Izuku’s entirely spent, but still manages to happily and tiredly chirp out a
“Yeah! I learned...a lot about myself. Thanks for everything as always!” as he
hazily searches for his bottoms that were tossed in the room. Katsuki’s already
snatched up his pants and, while wobbly the entire time, manages to get his
legs through. Izuku crawls to where his are, tossed under a few desks over, and
he uses the nearest desk as support as he shakily gets his own legs through his
pants.
“Go on then, my boys. Get cleaned up and never speak of this ever. Or else.”
All Might booms in his usual, chipper teacher like tone, shooing the two boys
out of the room as soon as they’re fully dressed and somewhat looking like
they’re put together.
Katsuki spits out a tame “Whatever.” as Izuku smiles, bows towards his idol,
and wheezes out another “Thank you!”
Slowly but surely, they head out the door, and All Might keeps the iconic smile
on his face the entire time as they do so. It isn’t until the door audibly
clicks that the man slumps down, hands on his knees and cock uncomfortably
going limp under his boxers and suit pants. He mutters out to himself, “...I
should not have done any of that.”
He doesn’t sleep that night. And judging by the clearer, rougher markings he
sees along Izuku and Katsuki’s skin that next day- ones that he knows didn't
come from his own hands, he assumes they didn’t either.
Guess they didn’t learn much after all. But that's a lesson for another day.
