****** When a Bully Loves His Nerd ******
by hopeless1665
Summary
     Katsuki can't help but bully Izuku endlessly. In his mind, if he
     doesn't, Izuku won't let go of his unrealistic superhero dream and
     could end up hurt or worse. Better to scare him and watch him from
     afar then have him close and end up dead. Izuku can't help but feel
     sad every time his childhood friend hurts him. He just wants them to
     be friends again, or better yet, more.
Notes
     So, this is my first My Hero Academia story. I hope you like it. And
     I don't have a beta so if you see mistakes, sorry.
Izuku cried as once again Kacchan bullied him about his dream. He slowly made
his way home, wanting to forget what his childhood friend had once again done
to him. He looked at the semi-destroyed notebook and felt tears spring to his
eyes again but wiped them away quickly. He thought of when he was little and
told by the doctor that he would never develop a quirk. He decided from then on
that no matter what others told him, he would be as great as All Might!
'That rights! You don't care what others have to say or what they think! Hold
your head up high and plunge forward!' Izuku walked through the tunnel he used
to get home and began to laugh to try and give himself the confidence boost he
needed at the moment. Before he made it half way through, however, a sludge
monster came out of the sewer and attacked him. Izuku felt terror like never
before, he could feel himself dying as the monster tried to force himself
inside.
'I'm gonna die!' Izuku glanced at his notebook and felt tears prickle his eyes.
Just as he began to lose consciousness, he heard a voice call out and a gust of
air hit him out of no where. He opened his eyes and could see a blurry person
in the distance. 'All...Migh...'
Then everything went dark.
-------------------------------------------------------------------------------
--------------------------------------
*Else where in the city while Izuku and All Might have their chat*
Katsuki drank his soda while listening to his "friends" chat behind him. He
didn't really care for them, they followed him because he was the most powerful
kid in school but he would ditch them when he got into U.A.
'Losers. Unlike them, Deku has a brain...and beautiful emerald eyes....and
soft, kissable lips....and G*D FUCKING DAMMIT!!!! STOP THINKING ABOUT DEKU AND
HIS FUCKABLE BODY!!!!' As Katsuki had his internal debate, his friends decided
to bring up Deku and why he always picked on him. One even had to gull to ask
why he tormented him if they were childhood friends.
'Because if I don't then fucking Deku might really try out for the Hero's
course at U.A. and end up fucking hurt!' Out loud Katsuki replied, "It's his
fault for getting in my way."
He kicked a bottle in anger as his thought of Izuku and how scared but
determined he seemed when talking about applying for U.A. He thought of how
hopeful his eyes seemed and Katsuki felt rage fill him. His friends told him to
calm down but Katsuki tuned them out.
"He's an idiot dreaming like a kid!" He blow up the empty can of soda in his
hand. "Just watching him pisses me off!"
His friends decided to change the subject and suggested the arcade for a change
of pace. Katsuki decided that he had nothing better to do and agreed to go. He
yelled at them when one suggested the arcade in front of the station because of
the easy prey. Just as Katsuki was berating them, a shadow appeared over head.
Katsuki saw the look of terror in their eyes and turned around to see what was
behind him.
Katsuki's eyes widened when he saw a wall of sludge with teeth come at him. He
felt himself being engulfed and taken over. His last coherent thought was of
Izuku. 'Shit, I never told him I was sorry.'
-------------------------------------------------------------------------------
------------------------------------------------------
*After Izuku and All Might's talk*
Izuku walked aimlessly, flipping there his hero notebook with no real thought
to his destination. All his thoughts were aimed at All Might and how his hero
had told him to give up on his dream. He thought back to how everyone who had
ever told him his dream was just a fantasy and for the hundredth time that day
felt tears spring to his eyes.
He sighed and closed his notebook after seeing All Might's signature. 'Even a
top pro said it.' he rubbed at his nose and tried to stop his tears. 'Don't
cry! You knew, didn't you? The reality. You knew. That's why you were trying so
desperately. You were averting your eyes, not looking at reality.'
Izuku came to a stop when he heard a crash to his right. Unconsciously, he had
walked to were to explosion from earlier had come from. Izuku guessed that out
of habit he had followed to where he thought a battle might be. He crossed the
street as he tried to convince himself to just walk away. He gasped as he saw
the monster from early and the destruction it had caused in such a short time.
He heard the people around him talking about the poor kid the monster had taken
hostage and how the hero's couldn't even get close. Tears made there way to his
eyes as he thought of the pain the person must be in and how All Might couldn't
save them because Izuku had wasted his time. He covered his mouth and prayed
that someone would help.
Izuku felt sadness run through him at his helplessness. Izuku watched as the
hostage struggled against the monster and gasped as he saw the eyes of Katsuki.
Before Izuku could think he was running toward the monster. He heard the hero's
at the scene yell at him to stop but all he could think about was saving
Katsuki. As he grew closer he thought of ways to save Katsuki. Izuku thought
about all the notes he had taken and thought about how to make the opponent
flinch. Once he was close enough, Izuku threw his backpack at the monster,
causing a book to hit it in the eye and for a few seconds it loosened its hold
on Katsuki.
"Kacchan!" Izuku immediately began to try and pull the sludge off Katsuki.
Katsuki gasped for air and felt horror fill him at seeing Izuku so close to the
monster that had control of him and his quirk. "Deku! Why the hell are you
here!?!"
Izuku continued to pull at the sludge while replying, "My legs moved on their
own! I don't know why, though!" Izuku pulled harder when he saw the monster
begin to engulf Katsuki once again. In his mind, he had no idea why he had
moved. No, that wasn't true. He knew, in that moment he knew why. "You looked
like you were asking for help..."
For the first time in a long time, Katsuki wanted to cry. He could do nothing
but plead to the monster to stop it. To not hurt Izuku. He watched as the
monster made to smash Izuku and he made one last plea, this time to the gods.
'Please, save Izuku!'
Just as the fist came down, a figure step in front of Izuku. Katsuki watched as
All Might saved Izuku and spoke to him about something Katsuki couldn't hear
over the blood pounding in his ears. He felt a fist grab his arm and felt
himself being pulled from the monster and thrown with Izuku out of All Might's
way. Katsuki pulled Izuku to the ground behind All Might and covered him as
best he could as All Might unleashed his ultimate attack, Detroit Smash!
Katsuki blacked out briefly at the air around him rushed past but just before
passing out he looked down at Izuku. He smiled as Izuku watched All Might in
amazement. 'Thank you All Might for saving Deku.'
When Katsuki regained consciousness he found himself surrounded by so-called
hero's. He sat up and immediately looked around for Izuku, wanting to make sure
he was truly alright. He ignored all the chatter around him and felt relief
flood him at seeing Izuku only a few feet from him. He frowned, however, at
seeing several hero's chastising and scolding him about running into danger
while they praised Katsuki for his endurance and quirk. He hated them, they had
stood their as he struggled against a monster and as Izuku rushed into danger.
Katsuki watched as Izuku was escorted away from the crime scene but was unable
to follow him right away. 'I'll catch him on his way home. And G*d fucking
dammit I'm gunna tell the little nerd how I feel.'
-------------------------------------------------------------------------------
-------------------------------------------
*Just after All Might tells Izuku that he can be a hero*
Izuku couldn't stop sobbing. His hero, All Might, who earlier that day told him
to give up on his dream, had just praised him and told him that it was possible
to be a hero. That he could inherit All Might's own power. He grinned at the
thought of training with All Might, which would begin in two days time.
"Deku!" Izuku turned around in surprise at hearing Katsuki call for him.
Through his tears he managed to reply, "Kacchan?"
Katsuki felt anxiety fill him at seeing Izuku in tears. 'He was fine when he
left the scene, right!?! If those fucking hero's let him go without a through
once over I'm gonna kill them.'
Katsuki didn't stop running until he was right in front of Izuku and could look
him over closely. He immediately grabbed Izuku by the shoulders and scanned his
front thoroughly before turning him around to scanned his back. He gulped at
the tight little ass of Izuku but saw nothing besides him being covered in
soot. Katsuki then turned him around once more and grabbed Izuku wrist and
began to pull him down the road.
"K-kacchan! Wh-what are you doing?!" Izuku didn't feel the terror he normally
did around Katsuki, whether that was because of the actions of earlier or
because Katsuki didn't seem to be radiating any violent intentions, Izuku
wasn't sure.
"Just follow me, fucking Deku."
They walked in silence, more like Katsuki pulled Izuku, but before it could get
too awkward they arrived in front of a modest looking home. Izuku remembered it
from when they were younger and he would visit Katsuki. Izuku felt Katsuki let
go of his wrist to pull out his keys to unlock the door. Katsuki glanced over
his shoulder and scowled at Izuku's dumbfounded look. "Well?! Come in, Deku!"
Izuku smiled timidly at Katsuki's command and followed him inside. Izuku
glanced around the dark hallway and could see that not much had changed. Izuku
snapped out of his thoughts when he heard the front door slam closed and
Katsuki throw his shoes by the front down. Izuku moved to take his shoes off
and placed them gently by the front door. He jumped as he turned around and saw
Katsuki staring at him. Katsuki made a noise and motioned for Izuku to follow
him.
Izuku stared at the floor as he followed Katsuki to what he remembered was the
way to the kitchen. He blinked as the kitchen light suddenly blinded him. After
a few moment he was fine and saw Katsuki pull out a chair. "Sit."
Izuku blinked once more but sat without complaint. Katsuki sat across from him
and silence once more hung over them. Izuku began to fidget. "Ummm, K-kacchan?"
Katsuki growled, "Shut up for three seconds, fucking nerd! I'm trying to gather
my G*d damn thoughts!"
Izuku sighed but nodded. "O-okay but can I m-make us something to eat?"
Katsuki grunted but Izuku knew that that was Katsuki speak for yes. He got up
and tried to remember where everything was. He opened the fridge to see a
package of beef strips with a note telling Katsuki to make it for his dinner.
Izuku glanced around and found several vegetables and decided to make some beef
stir-fry. He set to work getting out a pan and a cutting board. Within a few
minutes, the smell of food hung in the air. Katsuki watched every move Izuku
made and thought of how close he was to losing him.
Izuku could feeling Katsuki watching him and a blushed covered his face. He
began to get hot and took off his school jacket and without looking at Katsuki
placed it on the back on the chair he had previously occupied before returning
to the food. Katsuki silently gulped at being bale to see Izuku's ass more
clearly as he worked on dinner. After another eight minutes the food was done
and Izuku placed some in two bowls already filled with rice from the rice
cooker on the counter. Izuku placed one in front of Katsuki before sitting down
once more.
After saying the traditional pray both boys dug in. Katsuki was amazed at
Izuku's talent and remembered Izuku's mom being a wonderful cook as well.
Katsuki felt a small blush rise to his cheeks of the thought of Izuku always
cooking for him, always greeting him when he got home from work, always being
his.
"Deku."
Izuku paused in his eating to look at Katsuki. "Yes, Kacchan?"
"This is pretty decent." 'Can't you give a complement right you bastard!?!'
Izuku smiled and giggled. Katsuki knew he had never heard a sweeter sound.
"Thanks Kacchan."
They finished up quickly and Izuku washed the dished, humming a tone as he
relaxed in Katsuki's presences at last. Katsuki watched him once more and
thought of how he wanted to see this everyday for the rest of his life. Katsuki
got up silently and made his way over to Izuku. He made sure that Izuku had
nothing breakable in his delicate hands before wrapping his arms around Izuku's
small waist. He then nuzzled into Izuku's soft greenish black locked and could
smell soot but underneath was the unmistakable scent of Izuku.
Izuku gasped and tensed as he felt Katsuki wrapped his arms around him and
nuzzle his hair but relaxed when he felt Katsuki relax into him. He continued
washing the dishes, wondering about Katsuki's strange behavior but deciding not
to comment yet. Izuku finished quickly and they stood there in silence.
Katsuki broke the silence first. "You piss me off so much sometimes Izuku."
Izuku gasped softly at hearing Katsuki call him by his proper name but stayed
silent otherwise. "I go through the trouble of bullying you to try and keep you
away from any sort of heroing because I'm afraid that you could hurt yourself
and what do you do? You fucking run head first into danger to save my stupid
ass and almost end up dead. Please, tell me why you need to be a hero so
badly."
Izuku could hardly believe his ears. Two things today that he never thought
he'd hear. "You-you care? About me?"
Katsuki sighed, "That's all you get out of the fucking sentence. You really are
an idiot."
Izuku felt himself being turned around and a hand grab his chin gently to tilt
his head up. Emerald green met blood red as Katsuki smiled gently down at
Izuku. "Now listen here Deku because I'm only going to say this once. I love
you. I'm sorry I've bullied you all these years. I'm a jerk but I truly just
wanted to keep you safe. You, who is the kindest most gentle human being. You,
who wants to save everyone no matter how big a jerk they are. There's no real
excuse I can give you for any pain I've caused you except that I thought that
by showing you what a person holding back can do it might dissuade you from
putting yourself in danger."
Izuku felt tears make there way down his face. "I-I...I understand. I-it still
hurts to think of everything you've done and I don't think I'll ever really
forget but I forgive you. A-and I love you, too. I have since we were kids."
Katsuki felt a grin cover his face. "You're fucking perfect. I'll spend the
rest of my life making every second of pain up to you. For now, let me start
with this."
Katsuki leaned down and gentle kissed Izuku's soft pink lips. He nibbled the
fuller bottom lip and slide his tongue in when Izuku gasped softly. They
battled for dominance before Izuku allowed Katsuki control. Katsuki plundered
Izuku's mouth, mapping out every nook and cranny he could find. He pulled back
so they could catch their breathes and felt himself grow hard at Izuku mewl at
their separation.
"Fuck, Deku!"
Izuku yelped in surprise as Katsuki picked him up bridal style and carried him
upstairs to his room. Izuku wrapped his arms around Katsuki's neck and nuzzled
his cheek lightly, a smile making it's way to his face at the small blush on
Katsuki's cheeks. Katsuki was quick to open his door and just as quick to slam
it shut once they were inside. He wasn't worried about locking it since he knew
his parents wouldn't be home that night. All that mattered was getting himself
and Izuku naked as fast as possible. He gently laid Izuku down on his bed and
stood up. He was quick to remove his jacket, shirt, socks, and pants, leaving
him only in boxer briefs that his little to hide his large erection.
Izuku blushed at seeing Katsuki stripe but decided to be bold as well and
striped himself of hist shirt and pants as well. He blushed as Katsuki stared
hungrily at him. "K-kacchan, s-stop staring."
Katsuki smirked and climbed on top of Izuku, grabbing his wrists to pull them
over his head. He held both down with his right hand while his left traced
Izuku's left rosy nipple. Katsuki watched in fascination as the nipple hardened
without him having to touch it. "Fuck, you're sensitive. I'm going to have fun
ruining you for anyone else."
Izuku moaned at the helpless feeling and the hand tracing his chest but somehow
he had never felt safer. "K-kacchan?"
Katsuki moved his eyes away from the rosy nipple his fingers had begun to pinch
and looked Izuku in the eyes.
Izuku blushed brighter, if possible, under the heated look but gathered his
courage. "Kacchan, please, make me yours, now and forever."
Katsuki felt the air leave him. He never thought he'd heard Izuku telling him
to make him his. He died, he decided, he'd died and gone to heaven because Hell
was no place for an angel like Izuku.
"Fuck, Izuku. I'm gonna fuck you, I want to make love but I can't right now.
Later, but I have to make you mine."
Katsuki striped himself and Izuku of their underwear before letting go of
Izuku's wrist to reach for his bedside draw for his lube. Izuku glanced down
and felt his eyes widen at the site of Katsuki's cock. To Izuku, it looks more
frightening then the sludge monster. Okay, maybe not, but still...it had to be
at least 9 inches longer and 2 inches thick. It was a deep anger red with a fat
mushroom head. Over all, it was big and it made Izuku wiggle in both
anticipation and terror.
Katsuki crowed at finally finding his lube and moved to be between Izuku's
creamy thighs. Katsuki wanted to mark him up but decided that he didn't have to
patients for it at the moment. He opened the tube of lube and poured a good
amount on my fingers, wanting to make this as painless for Izuku as possible.
He looked down at Izuku once more and smirked as he saw Izuku staring down at
his cock.
"See something you like, Deku?"
Izuku stammered, "I-it's so b-big, Kacchan. A-are you s-sure it will f-fit?"
Katsuki groaned at Izuku's unintended dirty talk. "Fuck, fucking Deku. Yea, it
will fit in your tight, tiny ass. I'm gonna stretch you on my fingers until
your begging for my fat dick to be inside you. Only, I'm gonna make you wait
until you don't have any other thought in your head other than me fucking you
stupid. What do you think, Izuku, does that work for a deku like you?"
Izuku moaned loudly as one of Katsuki's fingers made its way inside him during
his little speech. "Y-yes! Kacchan! Please f-fuck me silly. I w-want you so
bad."
Katsuki leaned down to nibble on the rosy nipples that he had played with
earlier. Katsuki bit Izuku's left nipple before pulling gently. Izuku wailed as
pleasure and pain coursed through him. He barely noticed when Katsuki slipped a
second finger in and began to scissor them. Izuku moved his hands into
Katsuki's sandy blonde locks, hugging him closer to his chest. Katsuki growled
and released Izuku's swollen nipple to capture Izuku's lips once more.
Izuku felt his mind begin to become lost to the pleasure Katsuki was wringing
from him. He mewled at Katsuki plunged three fingers into his entrance while at
the same time fucking his tongue in and out of his mouth, mimicking what he was
going to be doing very soon. Katsuki pulled away and smirked at Izuku tried to
follow.
"Fuck Izuku, do you think your ready for my cock? Ready for me to fuck you
senseless and make you mine?"
Izuku nodded and wiggled.
"Not good enough. Beg you little fucking slut!"
Izuku opened his mouth but only little mewls made there way out. Katsuki
smirked and withdrew his fingers. Izuku cried out at the loss of fingers and in
seconds began to beg.
"Please, Kacchan! I w-want your f-fat cock inside me. Make me your l-little s-
slut."
Katsuki moaned and quickly lined himself up. He plunged quickly into Izuku,
knowing that the pain would be worse if he tried to go slow. Izuku opened his
mouth in a silent scream. Tears made their way down his face and he clamped his
eyes shut. "K-kacchan...it-it hurts."
Katsuki tensed and leaned down to cover Izuku's face in butterfly kisses.
"Sorry, so sorry. The pain will go away soon. Just tell me when I can move."
They stayed like that for several minutes, Katsuki could feel his patients
wearing thin as Izuku randomly tightened around him. Before he did something he
would later regret, Izuku moaned slightly and spoke softly, "Y-you can move
now, Kacchan. J-just please, be gentle."
Katsuki nodded and leaned down to kiss Izuku softly before beginning to move
slowly, pulling his cock out half way before rocking back in as gently as
possible. They kept this pace for a while before Katsuki felt the need to go
faster.
"Fuck, Izuku. I need to go faster. Can I go faster?"
Izuku could fell the pain ebbing away. "Yeah. Faster, Kacchan."
Katsuki immediately sped up, fucking Izuku harder and faster. Katsuki cried out
as Izuku suddenly tightened around him, his moans increasing in volume as
Katsuki struck something inside him. Katsuki aimed for the spot again and again
and each time Izuku cried out louder until he was screaming in pleasure.
"Fuck, Izuku! Fuck, your tight! I'm gunna cum soon. You hear that, I'm gonna
fucking dump my hot cum deep inside you and make you mine and only mine."
"Yes! Kacchan, please. Spill inside me, make me yours and only yours. Love you
and only you."
Katsuki felt something in him snap and he began to fuck Izuku as fast as he
could.
"Fuck, I'm cumming! I'm fucking cumming! Izuku!"
"Kacchan!"
Both came at nearly the same time. Katsuki slumped on top of Izuku as he made
sure their hip stayed snug together. Izuku moaned at feeling Katsuki's hot cum
inside him but smiled. He felt truly claimed by the perpetually angry boy. He
hugged Katsuki close, not caring that he was being squished. Katsuki noticed
that he was essentially smothering Izuku and rolled them so Izuku was laying on
top of him. Both moaned as their lower bodies were moved but both were too
exhausted to go another round. Today had proved a roller coaster for both of
them.
Izuku felt his eyes begin to droop. "Kacchan?"
"Yes, love?"
Izuku felt his insides warm at the new pet name. "When we wake up I have
something I need to tell you."
Katsuki yawned, "Fine, but sleep for now. Love you."
"I love you, too, Kacchan."
And with their confessions done, the boys fell into a deep and well-deserved
sleep, both unaware of how drastically their lives would change in only a
year's time.
And yes, Izuku forgot to call his mother, but that's a story for another time.
