     relationship was something they shared in secret.
     Includes: Pining Katsuki, Hot Dad Deku, Good Guy Kirishima, and a lot
     of sex
Notes
     This started as a joke on a Discord server, and I thought it would be
     funny to write it. "Lmao what if Katsuki was thirsty for his best
     friend's dad?" Then people kept talking, and it expanded into this
     giant thing.
     You really shouldn't think too hard about it. Unless you want to. I
     won't judge.
See the end of the work for more notes
The first time Katsuki met Izuku was when he was eight. Even before seeing him
face to face, Izuku had confused him.
“So…you want me to call your dad ‘Mr. Midoriya?’ ” Katsuki had asked. “But
you’re ‘Kirishima,’ right?”
“Yeah,” his friend replied. “ ’Cause ‘Kirishima’ was my mom’s last name.”
“So why isn’t your dad called that, too?”
He only received a shrug in response. Katsuki chose not to press any further,
despite the fact that he was curious as to where Kirishima’s mother even was.
When Katsuki first met Izuku, he went to Kirishima’s house. He hadn’t expected
it to be sobig. It was two stories tall—with a basement. It had a pool with a
slide and a diving board. Kirishima’s room had a high ceiling, bunk beds, and a
television with three different game systems.
Katsuki wondered what the heck his dad did to afford all of this.
It was around dinnertime that Katsuki finally met Izuku. He had peeked in
Kirishima’s room to see if he was getting hungry, and noticed Katsuki sitting
on the floor.
“Eijirou, did you bring a friend over? Why didn’t you introduce me?” he asked
with a smile.
Katsuki narrowed his eyes at how cheerful he was acting, especially when Izuku
bent his knees to extend a hand to him. He towered over Katsuki’s tiny body,
arms thick with muscle as his sleeves rolled up to his elbows. It annoyed
Katsuki how bright his eyes were, how messy his hair was.
“I’m Eijirou’s dad, Izuku Midoriya,” he said. “It’s nice to meet you.”
Katsuki huffed, taking his hand defiantly. He mumbled, “Katsuki.”
“Alright, Kacchan,” Izuku beamed. “I’m making curry tonight. Do you want some?”
Katsuki grumbled, “I like it spicy.”
Izuku laughed heartily, and nodded. “I can do that.”
After he left the room, Kirishima and Katsuki continued playing video games
until it was time to eat. In the middle of the game, Katsuki turned to
Kirishima, and said, “Your dad is weird.”
 
 
===============================================================================
 
 
A few weeks later, Katsuki saw Izuku’s name written on Kirishima’s report card.
“I thought your dad’s name was ‘Izuku,’ ” he pointed out. “Why is it written
like ‘Deku?’ ”
Kirishima looked at the paper in his hand. He laughed, “It can be read both
ways! Duh!”
Katsuki punched him in the arm.
 
 
===============================================================================
 
 
“Deku.”
Izuku’s fingers clicked rapidly against his laptop keyboard. His eyes never
strayed from his screen.
“Deku.”
Izuku paused, and swiveled his seat towards Katsuki. He was standing beside his
desk, staring at Izuku impatiently.
“Um…” Izuku glanced around the room before pointing to himself. Katsuki nodded.
“Kirishima wants to know if we can have popsicles.”
“Sure you can,” Izuku agreed. He waved Katsuki off before returning to his
work.
After a few minutes, he paused. He ran a hand through his hair.
“Deku…?”
 
 
===============================================================================
 
 
The first time Katsuki slept over at Kirishima’s house, he was ten. They had
been working on a project for school, and hadn’t finished by nighttime. Izuku
noticed how tired the boys looked, and suggested Katsuki spend the night. He
called Katsuki’s mother, who seemed thrilled to have a night alone with her
husband.
Because Kirishima was such a good friend, he let Katsuki have the top bunk, and
gave him his favorite stuffed orca to sleep with. Before they went to sleep,
Izuku came in to read a chapter of the book he had been using as a bedtime
story for Kirishima. Kirishima made sure to fill Katsuki in on the important
details so he wasn’t lost.
Katsuki had never listened to Izuku’s voice for so long. As he spoke, Katsuki
found himself paying less attention to the words, and more to the sound of
Izuku’s cadence. It was methodical, yet melodic. His tone changed depending on
who spoke. He was able to pitch his voice both higher and lower than Katsuki
had ever heard it.
It was hypnotizing.
Katsuki didn’t realize he fell asleep until Kirishima rustled him awake the
next morning with the enticement of chocolate chip pancakes.
 
 
===============================================================================
 
 
When Katsuki was eleven, Izuku went on a blind date. He brought Kirishima over
to his house to let Katsuki’s mother watch over him while Izuku was away.
“I’ll be back to pick you up in a couple of hours,” he told Kirishima.
“A couple of hours?” Katsuki’s mother laughed. “Don’t sell yourself short. What
if she wants to spend more time with you afterthe date?”
Izuku chuckled, and replied with a brief, “We’ll see.”
As Kirishima sat on the floor of Katsuki’s bedroom to play with their trading
cards, Katsuki couldn’t help but ask, “Why did your dad agree to that stupid
date if he didn’t want to go?”
Kirishima looked up from the card in his hand.
“How did you know he didn’t wanna go?”
Katsuki shrugged, and replied, “Just seemed like he didn’t care.”
“Yeah…” Kirishima sighed, pulling his legs up. “Dad says his coworkers told him
to do it, and he didn’t say no because ‘sometimes grown-ups have to do things
they don’t wanna do.’ I dunno. I just don’t like it.”
“Why not?”
Kirishima squeezed his arms around his knees. He murmured into his shirt
sleeve, “Whenever he goes on dates, Dad comes home really tired and sad. He’s
always quiet. He forgets to say ‘good night.’ I hate it.”
“Have you told him that?”
Kirishima shook his head, and mumbled, “No.”
“Kirishima.”
He lifted his head to see Katsuki standing in front of him.
“I recorded some anime earlier. Do you wanna watch it?”
Kirishima nodded, and they sat in front of the television until the doorbell
rang two hours later.
When Izuku knelt down in front of the doorway, Kirishima ran to his dad and
threw his arms around him. Izuku ruffled his hair as he stood back up, thanking
Mitsuki for taking care of his son.
As Mitsuki returned his gratitude by praising how well-behaved Kirishima had
been, Katsuki walked up to Izuku, and kicked him in the shin.
“Katsuki!?” his mother screeched. “What the f—heck is wrong with you!?”
Katsuki wrinkled his nose, and said, “Don’t go on any more dates, stupid Deku.”
Izuku stared at Katsuki with wide eyes as his mother grabbed him by the back of
his shirt to toss him inside. He listened through the door at Mitsuki’s
desperate attempt at an apology, and Izuku’s awkward reassurance that he was
used to it.
The next morning, Kirishima looked happier than usual.
Izuku never went on another blind date after that night.
 
 
===============================================================================
 
 
When Katsuki was twelve, he understood for the first time what it meant to
think of someone as “hot.” He had heard the other guys at school calling girls
“hot” when they walked down the hallway or sat together in the cafeteria.
One day, Katsuki asked what they meant whenever they pointed to a girl and
called her “hot.” The response he got was a shrug and a simple reply of, “It
means you wanna fuck her.”
Katsuki knew what that meant. He had watched porn before, but never understood
what the big deal was about it. Girls looked too soft to him, and they made
annoying sounds. When he looked at girls, he started to think he might
accidentally break them.
Kirishima never talked about girls like the other guys did, so Katsuki often
found himself hanging out with him after school. They did homework, or played
games, or swam in his pool. Sometimes Izuku would bring them snacks, smile at
Katsuki, and say, “Always good to see you, Kacchan.”
Katsuki never told Kirishima that was one of the reasons he came over.
One afternoon, Katsuki walked home with Kirishima, and saw Izuku outside the
front of the house. He was kneeling down beside a large bicycle, adjusting the
chain along the back wheel. His eyes focused intensely as sweat dripped down
his brow.
“Hey, Dad! Finally fixing up that old bike?” Kirishima called out to him.
Izuku instantly perked up, waving a gloved hand at Kirishima. He grinned and
laughed, “Yeah, finally! I had a feeling Kacchan would come over, so I have
dinner in the oven right now! It’ll be ready in about ten minutes!”
“Awesome! Thanks, Dad!” Kirishima cheered, throwing him a thumbs up. He
continued walking to the door, but Katsuki lagged behind him.
Izuku turned back around, hunched over the bicycle as he examined the wheels.
Katsuki watched his shoulders flex into the white fabric of his tank top. His
loose shorts rose up his thighs as his ass bent over the seat.
Katsuki’s throat felt dry. His fist clenched around the strap of his backpack.
For a brief moment, he had a thought. A thought that maybe he should ignore
Kirishima’s invitations to follow him inside, and instead throw himself over
Izuku’s body and lick the sweat off his biceps.
It was then that Katsuki understood.
Izuku Midoriya was “hot.”
That night, when he returned home, he changed his porn search terms to “men
only.”
 
 
===============================================================================
 
 
When Katsuki was thirteen, he was deep in the throes of puberty. His face
started breaking out, he was growing hair in unmentionable places, his voice
was lowering, and he found himself feeling horny more often than he liked to
admit. In a word, it sucked.
Kirishima bragged about how much his junk was growing, but Katsuki kept that
sort of information to himself. Even if it was a joke, he was
uncharacteristically self-conscious about divulging exactly how big his dick
was getting. Especially with Izuku nearby.
Izuku had become a prominent figure in his hormonal fantasies, often laying
himself out for Katsuki to dig into like a steak dinner. Izuku never struggled,
never complained. He worshipped Katsuki in his dreams, begged for more of his
cock, for Katsuki to fuck him slow and hard.And Katsuki wanted nothing more
than to give him everything.
Katsuki visited Kirishima’s house almost every day, and started spending the
night more and more. His best excuse was getting Kirishima so invested in
studying or games that they “just lost track of time,” and Katsuki knew it was
too late to walk home by himself. Izuku was always more than happy to promise a
large helping of pancakes or waffles the next morning.
Sometimes Katsuki was lucky, and Kirishima would fall asleep while they
studied. He would use this opportunity to find Izuku in the kitchen or the
living room, and spend the rest of the evening talking to him as he baked or
watched television. Whenever Izuku smiled or laughed, Katsuki resisted the urge
to slam him into the couch and have his way with him. It was always torture
when Izuku stood up, brushed off his pant legs, and said he and Kirishima
needed to get ready for bed.
The one thing Katsuki hated about visiting Kirishima’s house was Izuku’s strict
ten-o’clock bedtime rule. He always had the two in bed with teeth brushed by
ten, so they would be well-rested by the next morning. Katsuki loathed giving
up even one minute he could have spent with Izuku. However, it soon became
clear to him whyIzuku made the boys sleep so early.
It was a cold night, and Katsuki quickly realized that he forgot to use the
toilet before getting in bed. He tossed and turned under the three layers of
blankets Kirishima had given him, spending a good hour debating whether or not
he should bite the bullet and make his way to the bathroom. It was almost
midnight when he finally descended the ladder of Kirishima’s bunk bed.
After successfully emptying his tank, Katsuki headed back to Kirishima’s room
down the upstairs hallway. He paused at the fork in hall leading to Izuku’s
room and study. The door to his bedroom was wide open, and the door to his
study was slightly ajar. A faint light cast a white sliver along the wall.
Slow and purposeful, Katsuki stepped forward.
Muffled noises grew louder as he inched closer to the door. It sounded almost
like crying, like someone was struggling to keep their voice down. Katsuki
could hear the subtle creak of Izuku’s office chair leaning back. Finally, he
peeked through the crack.
His heart dropped to his stomach.
Izuku sat in front of his laptop, headphones covering his ears, watching a
video on the screen. Katsuki could see he had both hands between his legs, and
his pants and underwear were bunched around his ankles. Izuku’s left hand
jerked up and down, echoing hard, slick slaps throughout the spacious room. His
head tilted back, and Katsuki heard him suck in a breath through his teeth.
When Izuku exhaled, it left his lips as a quiet, “God, yes…”
Katsuki threw a hand over his mouth. His pulse raced. The force of a pistol
shot heat straight to his dick. He needed to leave. He knew he needed to leave.
But then, Izuku shifted his position, and his other hand slid lower.
Izuku bit down on his bottom lip, and closed his eyes. Katsuki listened to him
hiss and moan as two fingers pressed into his ass. They moved for what felt
like an eternity. Izuku’s thumb twisted around the tip of his cock. A deep sigh
passed from his lips.
“Fuck me,” he breathed. “Fuck me…”
A shiver ran down Katsuki’s spine. He didn’t move—and it was then that he
realized he had been rubbing himself through his boxers. Trying his best to be
quiet, Katsuki ran back to the bathroom.
Once he had shut the door and locked it, he yanked off his underwear, and
stared down at his red, swollen cock. He wrapped his fingers around it,
mimicking Izuku’s motions. His voice sang in Katsuki’s mind.
Fuck me.
Fuck me, fuck me…
Kacchan .
Fuck me, Kacchan…
Katsuki had never before seen so much spunk in his hand after he came.
 
 
===============================================================================
 
 
“Is your dad gay?”
Kirishima turned to Katsuki after he asked the question, and balked.
“I don’t…think so?” he said, scratching the back of his neck. “But I mean…I
guess the only person I know he loved was my mom.”
“Love?” Katsuki quirked his brow. “What about sex?”
“Gross, dude!” Kirishima chuckled awkwardly. “Why’re you making me think about
my dad having sex?”
Katsuki didn’t flinch as Kirishima playfully socked him on the shoulder. He
mindlessly clicked the controller in his hand, letting Kirishima win the next
round of the cart racer they were playing.
 
 
===============================================================================
 
 
Katsuki was fourteen when he made up his mind.
More accurately, Katsuki was fourteen when an opportunity arose in which he had
to make up his mind.
In the dark, almost unsettling air of midnight, Katsuki headed down the stairs
of Kirishima’s house towards the kitchen. He grabbed a glass from one of the
cabinets, and poured himself some cold water. As he did, he heard sudden,
hurried shuffling from the living room.
Katsuki peered over the open counter into the dimly lit area of the next room.
Accented by a thin layer of moonlight, he could make out Izuku’s wild curls
behind the couch cushions. Clutching the glass tightly in his hand, Katsuki
started walking to him.
When he arrived at the couch, Katsuki could see Izuku had carelessly tossed a
tablet and earbuds onto the coffee table in front of him. He was wearing a
loose shirt and pajama bottoms, but they seemed quite ruffled. His arms were
placed firmly over his lap, and his eyes shimmered as he looked up at Katsuki
with a wide gaze.
“H-hey, Kacchan,” he greeted softly. “Thirsty…?”
“Yeah,” Katsuki answered, more honest than Izuku realized. “You?”
“Oh, I’m fine.”
Liar, Katsuki wanted to say. Instead, he bit his tongue, and sat down beside
Izuku.
“What are you doing up?” he asked.
“Couldn’t sleep.”
Fucking liar, Katsuki again wanted to say. He set his glass down on the coffee
table with a quiet tap, and scooted closer to Izuku.
“You know, I’m not a little kid anymore,” Katsuki said, voice pulled taut. “You
don’t have to keep calling me ‘Kacchan.’ ”
Izuku’s toes curled. He chuckled, “You’ll always be ‘Kacchan’ to me, though. I
can still see that grumpy little boy I used to feed mac-and-cheese to on
Saturday afternoons during summer vacation.”
Katsuki shoved his palm against Izuku’s chest, pushing him back further into
the couch. He glared down at the larger figure seated next to him.
“Is that all?” he hissed. “Is that allyou see, Deku?”
“…Kacchan.” Izuku gulped. “I don’t like your tone right now.”
Katsuki’s hand slid to Izuku’s neck, trailing higher to cup the thick outline
of his jaw. He could feel Izuku’s faint stubble scratch at his fingertips.
“Tell me what you see,” Katsuki whispered, leaning closer towards Izuku’s face.
His tongue flickered out to wet his lips. “Look at me now, Deku.”
“Kacchan,” Izuku said, breath wavering. “You don’t want to do this.”
“You have no fucking idea how long I’ve wanted to do this.”
Katsuki closed the distance between them.
Izuku immediately grasped Katsuki’s shoulder, but seemed hesitant to push him
away. This only urged him to keep going, to grab Izuku’s face in his hands and
pull their mouths even closer, deeper. He melted into Izuku, like a candle
swallowing him with hot wax, a reign of fire that danced on their tongues.
Katsuki swung his knee over Izuku’s body, placing himself in the middle of
Izuku’s lap. Something hard and thick rubbed against his sweatpants. Katsuki
broke the kiss, and panted quietly.
“Deku… Come on, Deku,” he sighed, tugging at the waistband of his pajamas. “I
know you need this. Let me do it. Let me take care of you…”
Katsuki nipped at Izuku’s ear, listening to him keen in response. He committed
the gorgeous sound to memory, but knew he was hungry for more. Izuku trembled
beneath Katsuki’s hands as they pulled down his pants, freeing his cock for
Katsuki to gaze upon. His fat, musty, mouth-watering slab of a cock.Katsuki
shivered, so eager, so ready to pump every last drop of cum from Izuku’s finely
waxed balls.
“Wanna fuck you so bad,” Katsuki hissed, taking Izuku in his hand. “Shit, Deku,
wanna make you mine…”
“K-Kacchan…” Izuku mumbled into his sleeve.
“Told you not to call me that,” he snapped.
His fingers curled around Izuku’s length, and Katsuki heard him sniffle.
He paused, asking, “Are you…crying?”
Izuku shifted, wiping the back of his hand across his eyes.
“Sorry,” he sobbed. “Sorry, I… It’s just…”
“It’s been too long, right?”
Izuku said nothing. He nodded.
Katsuki kissed him again. This time, it was slow. Passionate.
“Deku,” Katsuki murmured, threading his fingers into Izuku’s hair. “Tell me
what you want.”
Izuku took a deep breath, and settled into his hold.
“Fuck me,” he whispered.
Izuku’s legs spread as he gripped Katsuki’s waist, dragging him down to sit
between his thighs. Katsuki stared ahead at Izuku’s broad chest, rising and
falling with every silent gasp. His burning eyes ran up Izuku’s neck to his
face, eventually settling on his own expanded, moonlit pupils.
Izuku slowly, firmly rocked his hips. He moaned.
“Fuck me, Katsuki…”
In an instant, Katsuki hovered over Izuku as he laid back against the couch.
“Deku…” he huffed, heart pounding in his chest. “God, fuck,you’re so fucking
hot…”
 
 
===============================================================================
 
 
Izuku didn’t talk to Katsuki for a while after that night. Katsuki still went
to Kirishima’s house after school, but Izuku often kept to himself by working
in his study. They never saw or spoke a word to each other for almost a month.
It was something even Kirishima noticed as strange.
“Dude. Bakugou. What the hell did you do to piss of my dad?” he eventually
asked.
Katsuki scrunched his nose in annoyance. “Fucking nothing.”
“Well, I know that’s a load of bull,” Kirishima sighed, crossing his arms.
“I’ve never seen him like this before. Dad’s usually so upbeat. But now,
whenever you come over, he gets real quiet and locks himself up. It’s kinda
creeping me out.”
“You and me both,” Katsuki grumbled under his breath.
“It’s almost like…he’s really upset for the first time in his life, and he
doesn’t know how to deal with it,” Kirishima said.
Katsuki thought on those words. There was no way Izuku was angry.Katsuki had
seen his face the moment he sprayed his cum all over the couch cushions. Izuku
had been the happiest bastard on planet Earth that night. But…maybe Kirishima
was onto something.
Maybe Izuku was feeling some sort of crazy emotion he’d never experienced
before, and didn’t know how to deal with it, but had identified Katsuki as the
cause. It seemed like the only way he knew how to solve this problem was to
distance himself from the source.
Well, Katsuki thought, two can play at that game.
 
 
===============================================================================
 
 
For the next few weeks, Katsuki distanced himself from Kirishima’s place. He
visited less often, and began cutting his time spent there shorter and shorter.
Soon, he stopped coming over to Kirishima’s house altogether. He even started
inviting Kirishima to his home instead.
For a while, Katsuki was unsure if his plan was working. He received his answer
when Kirishima complained to him one evening as they finished their homework.
“I thought that maybe Dad would get better, but it feels like he’s getting
worse,” Kirishima told him. “He spaces out so much at home now… I’m worried
that he’s not getting enough sleep.”
“Really? Let me come over tomorrow. I wanna see for myself,” Katsuki replied
nonchalantly.
Kirishima reluctantly agreed, and the next day, Katsuki stood beside him as
Izuku opened the door for them to come inside. When he saw Katsuki, his face
lit up for a brief moment.
Success.
While Kirishima set up the game station Katsuki asked to play, he wandered into
the kitchen, finding Izuku at the counter, staring deeply into a cookbook.
“Hey, ’sup, Deku?” he greeted.
“Kacch—” Izuku shot up like a flame, but quickly put himself out. He cleared
his throat. “Good…evening.”
Hell no.
Katsuki clicked his tongue, and moved closer.
“Kirishima tells me you’ve been feeling kinda down lately,” he said with a
grin. “So what’s bothering you?”
Izuku fidgeted with his hands. “It’s nothing. Eijirou’s just a worrier, like
his dad.”
Katsuki raised his brow. He chuckled, “I see. So…you aren’ta little bit sad?
Maybe upset? Afraid? Lonely…”
Izuku kept his body perfectly still. He swallowed thickly. “Why would you think
that?”
“Because,” Katsuki murmured, now inches from Izuku’s side. “We haven’t fucked
in almost two months.”
Izuku clenched his fists against the granite countertop.
“Katsuki,” he hissed. “Don’t speak to me that way.”
“Holy shit, you are angry,” Katsuki laughed, cocking his head. “But say my name
again. That was fucking hot.”
“I mean it.”
Izuku slammed his palm down, glaring a hole through Katsuki’s face. The grin on
his lips only got wider.
“Prove it,” he challenged. “What are you gonna do, huh? Punish me?”
Katsuki’s fingers slowly wrapped around the tie that hung from Izuku’s neck. He
gently tugged at it, pulling Izuku down to his level.
“Can you think of a good way to shut me up, Deku?”
Izuku ripped Katsuki’s arm off his tie by grabbing at his wrist. His face was
red with a mixture of all kinds of inappropriate emotions an adult should not
be directing at a teenager. He threw a large hand over the top of Katsuki’s
head, and pushed him onto his knees. Katsuki bit his lip when his nose pressed
against Izuku’s belt buckle.
The clicking sounds of the small piece of metal roared like waves of thunder to
Katsuki’s ears. When Izuku’s belt dropped to the floor, his fingers dragged
agonizingly slow as they pulled down his zipper. Katsuki sucked in his cheeks
at the sight of Izuku’s underwear bulging through his open fly. He reached out
to touch it, but Izuku swatted his hand away.
“Don’t touch,” Izuku chided. “You’ll do as I say. You’ve been a badboy,
Kacchan. You need to learn your lesson.”
Katsuki squirmed, dick rock hard in his pants. He nodded, and replied, “Yes.”
His face was immediately shoved into the musky fabric of Izuku’s boxer briefs.
“Yes, what?” Izuku spat down at him, burying his fingers in Katsuki’s ashen
locks. “What am I, Kacchan?”
Katsuki shivered, arching his back. He panted, so soft, so eager, “Yes, Daddy.”
Izuku kneaded his fingers through Katsuki’s hair, and let out a long, satisfied
groan. He pet behind Katsuki’s ear, and smiled at the gentle purr he was given
in response.
“That’s right,” Izuku sighed. He let go of Katsuki to hook both of his thumbs
around his underwear. “Now, Kacchan…”
He paused, letting his cock bounce up against his stomach. It was larger than
Katsuki remembered it being. So red and thick and already dripping with cum,
practically weeping with it. Crying for Katsuki to wrap his warm, wet tongue
around the head and suck.
Izuku swept his fingers under Katsuki’s chin, and tilted his head to look up.
“…Be a good boy, and show Daddy you know the rightway to use your mouth.”
 
 
===============================================================================
 
 
Two days later, Katsuki spent the night at Kirishima’s house for the first time
in almost a month. He sat across from Izuku at the dinner table, and they both
exchanged a look that clearly said, “Meet me later.”
Katsuki waited until Kirishima was fast asleep, which wasn’t difficult to tell,
because he snored like a jackhammer. His head thudded with excitement for every
step he took towards Izuku’s bedroom. The first thing he saw after turning the
door handle was Izuku’s face framed by the yellow glow of his bedside lamp.
Izuku turned to look his way, a pair of reading glasses resting on the bridge
of his lightly freckled nose. The book in his hands instantly fell shut, and
Izuku placed it next to the lamp. Katsuki walked towards him, watching his
fingers carefully push the buttons of his pajama shirt. Izuku’s eyes danced
across his body with a fluttering, come-hither stare.
Katsuki practically leaped onto the bed.
That night was the first time Katsuki fucked Izuku properly. It was more
intense than he ever imagined. His insides threatened to spill from his body.
His head nearly burst from the heat in his face. Izuku’s fingernails clawed
deep welts into his backside, burning, stinging his skin with proof of his
lust.
They reluctantly held back their voices, wishing with every breathless cry that
they could scream the other’s name. Izuku bit into his shoulder, muffling his
whimpers of Kacchan, Katsuki, good boy, good boy, through his teeth. And
Katsuki fucked him so quietly,moaning his name, moaning Deku, Izuku, Daddy,
Daddy, so gently one would think he was fucking God himself.
It was close enough.
It felt strange to cum into a condom, but Izuku helped him take it off, and
praised Katsuki for doing such a good job without any experience. It ruffled
his feathers a bit, but he decided to take the compliment. Katsuki promised he
would get better, and Izuku giggled. It was like listening to an angel sing.
Katsuki lay on top of Izuku for a long time, letting him pet his hair in
relaxing motions until sleep overtook him. The next morning, he wondered if he
dreamt the whole thing when he woke up back in Kirishima’s bed. It wasn’t until
he saw Izuku making breakfast in the kitchen, humming to himself as he placed
batter in a large muffin tin, that he knew.
As Izuku walked to the oven, Katsuki noticed he was limping.
 
 
===============================================================================
 
 
“Dude.”
Katsuki whirled around at the sound of Kirishima’s voice. He and a couple of
his classmates were staring at his backside as they changed clothes in the
locker room.
“What the heck happened?” he asked, pointing to the prominent red streaks that
lined Katsuki’s bare back.
He glanced over his shoulder, and shrugged. “You know. Whatever.”
Katsuki heard Kirishima click his tongue as he pulled his gym shirt over his
head.
“Man,” Kirishima sighed. “Never thought you’d be the first one to hook up with
a girl. She must be wild, though. Was she older or something?”
Katsuki tugged at the hem of his shirt, and grunted, “Yeah. Or something.”
He waited until Kirishima turned around to change before a smug grin crossed
his face.
 
 
===============================================================================
 
 
When Katsuki was fifteen, he heard Izuku scream his name for the first time.
Both he and Kirishima were getting ready to take their high school entrance
exams, and Izuku decided to hire a tutor for his son. Every Thursday, Kirishima
stayed late after school to meet with the tutor, and Katsuki met with Izuku as
he worked from home. Kirishima didn’t even think to question why Katsuki was
always waiting for him when he returned.
The first afternoon it happened, Katsuki felt a nervous excitement bubbling in
his stomach, reminding him of when he was six years old, standing on a diving
board for the first time. The door to Izuku’s room swirled before his eyes like
a deep, endless pool of ice cold water. When he entered, Izuku was already
naked on the bed.
Chest muscles flexed as his back arched sharply, fingers sliding in and out
with quiet, squelching noises. Izuku panted, harsh and hot, and turned his
heavy-lidded gaze to Katsuki’s face.
“I couldn’t…wait…” he whimpered, fingers thrusting faster into his hole.
Katsuki felt the air get punched out of his lungs. He swallowed, and grinned.
“Deku… Aren’t you the one who’s always telling me to be a ‘good boy?’ What am I
supposed to do aboutthis?” he laughed, sitting down beside Izuku on the bed. He
rested a hand on Izuku’s cheek, savoring the way he trembled under his touch.
Katsuki sighed, “Look at you…”
Izuku wet his lips, breath hitching as Katsuki tugged on one of his nipples. He
moaned, deep and needy and slutty, “Fuck, I don’t care…”
Katsuki slammed their mouths together, shoving his tongue down Izuku’s throat.
Izuku groaned, and grasped the back of Katsuki’s head to pull him closer, as if
he wanted Katsuki to eat him whole.
“Kacchan…” he purred against Katsuki’s lips. “Daddy wants you to be a bad boy
today.”
Katsuki couldn’t remember exactly how fast his dick went inside Izuku, but that
fact that he didn’t know meant it was the fastest he’d ever managed to stuff
him full of cock. The moment Katsuki was buried balls-deep in Izuku’s ass, a
sound passed from his lips that Katsuki had never heard before. A long,
loud,unrepressed, unmistakable wailof pleasure that Izuku didn’t bother to hold
back at all.
The corners of Katsuki’s mouth twitched into an eager grin, so ready to hear
more, more,and to fuck Izuku better than any cock he’d ever had. He leaned
forward, brushing his lips along Izuku’s neck, murmuring lewd promises into his
skin.
“Gonna fuck you so hard, so good, fuck, fuck,” he growled, massaging firm
circles into Izuku’s hips. “Tell me how badI am, Daddy.”
“So bad, so bad,Kacchan…” Izuku groaned, voice rugged and sandy as it caught in
his throat. His legs wrapped around Katsuki’s waist, and Izuku whined, rutting
himself into his smaller body, “Oh, God, fuck,Katsuki…!”
Katsuki thought in that moment that he didn’t need to go to heaven after this.
He had already grasped the full experience here, on Izuku’s bed, listening to
this wonderful, gorgeous man more than twice his age crying his name as he
beggedfor his cock.
“Harder, harder,” Izuku ordered, tossing his head back and clawing at the bed
sheets.  “Fuck me… Fuck me, Katsuki!”
At the sound of his name, at the sound of Izuku calling his name,Katsuki braced
himself on the bedpost behind Izuku’s head, and pounded his ass until Kirishima
texted his dad to tell him he was on his way home.
 
 
===============================================================================
 
 
Kirishima wasn’tthatstupid. Katsuki knew that better than anyone. As his best
friend, he could tell over the years what it was Kirishima excelled at, and
what he needed to work on. He wasn’t “book smart,” but he was“people smart.”
Kirishima knew how to make people smile, how to bring a a group together, and
how to mediate fights between rowdy classmates. He had the valuable skill of
being able to read people’s emotions, and could usually tell exactly what was
going on with everyone he knew. Everyone he knew except Katsuki Bakugou.
“I just don’t get it,” Kirishima said to him one day. “You’ve been happier than
I’ve ever seen you lately, and I can’t figure out why.”
Katsuki didn’t reply, only rolled his shoulders in disinterest. He did notwant
to have this conversation.
“Listen, Bakugou,” he continued. “You’re my best bud, so I want you to know
that you can come to me about anything. And that includes when something
goodhappens, you know!”
“Yeah, yeah,” Katsuki grumbled.
Kirishima pouted. “I’m serious! C’mon! I gotta know! Did your parents win the
lottery? Have you gotten back your exam results? Are you seeing someone? Is it
a girl?”
“Oh my fucking God, shut the hell up!”
They were both quiet. Katsuki panicked. He hadn’t meant to snap like that, but
the thought of Kirishima telling Izuku he had a girlfriend made him boil with
rage.
Kirishima placed a hand on his shoulder, and nodded. “It’s okay, man. I get
it.”
“…You what?”
“I understand,” he sniffed, wiping away a tear that wasn’t even there. “You
have to keep it a secret…because her parents don’t approve of you.”
Katsuki’s eye twitched. Kirishima grabbed him dramatically.
“Don’t worry, Bakugou!” he cried. “I’ll support you all the way! I know what a
great guy you are! You’d never do anything to put your significant other in
danger!”
Katsuki bit his tongue, willing himself not to ask if potential statutory rape
charges counted as “danger.”
 
 
===============================================================================
 
 
When Katsuki was sixteen years old, he and Izuku had sex in public for the
first time. Sort of. It was close enough for Katsuki, anyway.
It happened on the day of Kirishima’s sixteenth birthday. He had decided to
throw a party at his house, and invite all of their friends at their high
school. The house was definitely big enough, and most people ended up outside
to swim in the pool or make out on one of the lawn chairs. Katsuki stayed
inside, preferring to help Izuku restock the food as hungry teenagers gobbled
it up. Eventually, they both gave up and ordered a dozen pizzas.
“They said it’ll take an hour,” Izuku told Katsuki, hanging up his phone. “So
we’ll just have to wait.”
Katsuki folded his arms, now rougher and thicker since he’d grown more muscle,
and grinned. “So what do you wanna do?”
“I guess I’ll go check on the kids to make sure no one—”
“I’m asking,” Katsuki interrupted, placing himself between Izuku’s legs. “…What
is it you want to do,Deku?”
Izuku paled, tapping his fingers against the kitchen counter. He glanced around
to make sure no one could see them. Katsuki watched his Adam’s apple bob as he
gulped.
“I think…” Izuku whispered, leaning down to speak into Katsuki’s ear. “I want
to my baby boy to take care of me.”
Katsuki chuckled, and stroked the back of Izuku’s neck. “I can do that, Daddy.”
“Fuck, Katsuki, c’mere,” Izuku groaned, grabbing his wrist to pull Katsuki up
the stairs.
They didn’t even make it down the hall to Izuku’s bedroom before he pulled
Katsuki into the study and locked the door behind them. He threw Katsuki
against the wall, kissing him fiercely, rubbing his hands up and down the thin
tank top that covered his torso. Katsuki moaned into his mouth, and Izuku
shivered. His knee slipped between Katsuki’s thighs.
“Kacchan,” he panted, brushing their lips. “Fuck me on the desk.”
Katsuki choked on saliva he didn’t know was his or Izuku’s.
“You sure?” he asked.
“Yeah, yeah, I’m sure,” Izuku replied, trembling with excitement.
“Please,Kacchan, be a good boy for Daddy…”
No one at the party heard Izuku’s pleasured cries over the loud music that
played from the giant sound system in his living room. The pizza arrived
earlier than predicted, and Kirishima answered the door to sign for it.
 
 
===============================================================================
 
 
Katsuki had practiced fingering himself for a good three months before finally
springing the idea to Izuku. It happened on a night when Katsuki stayed over to
help Kirishima with a science project, and he fell asleep halfway through
Katsuki’s explanation as to whyphysics worked the way it did. It started out
the same as it did any night, where they exchanged quiet kisses on Izuku’s bed,
but Katsuki was the first to pull away and speak.
“Hey…Deku,” he began, softly. “How about…we switch things up tonight?”
Izuku looked at him, confused. “You mean try a new position?”
“No, I mean…” Katsuki glanced away and sucked in his lip. “I mean…I want you
inside me.”
Once again, Izuku stared. “I don’t understand.”
“For fuck’s sake—look,” Katsuki growled, placing his hands on Izuku’s
shoulders. “I may be young, but I’m still a man. I know what a man wants.”
He could see Izuku start to sweat. His face flushed with embarrassment, and he
seemed hesitant to say anything in reply. Katsuki sighed, and continued.
“Don’t you miss that feeling of actually beingon top?” he asked. “I can give it
to you, Deku.”
Izuku fumbled and stammered, “I-it’s just…I don’t w-want to feel like I-
I’mforcing you into this, Kacchan. We’ve…a-already gone so far.”
Katsuki scoffed, “Exactly. That’s why nothing should matter anymore. Let’s just
go all fucking the way, Deku.”
Katsuki’s hands cupped the sides of Izuku’s face, dragging him in for another
slow, firm kiss. Izuku relaxed, resting his hands on Katsuki’s waist. With a
grin, Katsuki pulled himself higher onto Izuku’s lap, and grinded his ass
against the bulge under his boxers. Izuku quivered like a hummingbird, fingers
twitching to hold Katsuki tighter.
“Come on…” Katsuki coaxed, a smile curling into his words. “Fuck me, Daddy.”
Their positions instantly flipped, and Katsuki found himself staring up at
Izuku’s face, desperate and shadowed in the dark light if the room. Izuku held
down his wrists, so much bigger than they were a few years ago, yet still
nothing compared to the monstrous bulk of Izuku’s frame. Katsuki eyed his body
with an insatiable hunger.He wantedthis. He was ready.
“How long have you been waiting to hear that?” he laughed.
Izuku squeezed his arms, and said, “You have no idea.”
 
 
===============================================================================
 
 
Katsuki yawned, stretched, and climbed over the side of Kirishima’s bunk bed.
The minute his feet hit the ladder, he winced. A sharp pain rocketed down his
spine and dive-bombed straight to his ass. He coughed, trying to hide the
uncomfortable whimper that threatened to break free from his throat.
Kirishima looked up at him with a worried expression. He asked, “You okay,
Bakugou?”
“Yeah, ’m fine,” he lied through his teeth.
Katsuki shuffled his way to the stairs, and bit down on his cheeks as he
slowly, carefully walked down each of the steps one by one. Every inch he
descended was torture. Kirishima continued to glance at Katsuki every so often.
Izuku was waiting for the boys in the kitchen, having already baked them fresh
chocolate chip and banana pancakes. He loaded their plates with more than
usual, and Katsuki noticed he’d been given an extra two. When his eyes met
Izuku’s, he bit his lip and gave Katsuki the most apologetic look he could
muster.
 
 
===============================================================================
 
 
Katsuki was not quite seventeen when he and Izuku were almost caught. It
happened on a night when Kirishima wasn’t home, and Katsuki was getting bored
with the episode of the detective drama he and Izuku were watching. He began
teasing his foot against Izuku’s, urging him to lean in closer, to wrap his arm
around his shoulder tighter. He rubbed a hand along Izuku’s thigh, and they
instantly migrated to the bedroom.
It had been going so well, too. Izuku moaned like a harlot every time Katsuki
flicked his tongue across one of his nipples. His mouth traveled lower, kissing
wet marks down Izuku’s rough, defined abs. Katsuki licked a moist, sloppy trial
along the underside of Izuku’s cock before taking it deep to the back of his
throat. The scream that tore from Izuku’s lips was ethereal.
Katsuki grasped Izuku’s legs to swallow his cock a few more times when—out of
nowhere—they heard the lock to the front door click.
Katsuki shot up, and he and Izuku both turned to look at the digital clock
beside his bed.
“Nine twenty-eight!?” Katsuki screeched. “I thought you said the game ended at
ten!”
“It was supposed to!” Izuku hissed. “The other team must have been terrible.”
Katsuki growled in frustration, but stopped all his movements when he heard
footsteps heading up the stairs.
“Kacchan, get off,” Izuku ordered in a voice that would have been unbelievably
fucking sexy if he wasn’t glaring daggers at him, too.
Katsuki rolled off the bed onto the floor, and quickly grabbed every article of
his discarded clothing. He then crawled back to the bed, and hid behind the
side that faced away from Izuku’s bedroom door. It creaked open just as Katsuki
had curled up as flat as he could.
“Hey, Eijirou,” he heard Izuku greet cheerfully. Katsuki noted he was getting
better at controlling his nervous stammer. “Back so soon?”
“Yeah, we totally kicked ass out there,” Kirishima laughed. “Are you going to
bed this early?”
“Yeah, I’m feeling pretty tired.”
“Oh.” Kirishima paused. “Is Bakugou here?”
Katsuki’s stomach lurched into his esophagus.
“No, he’s not,” Izuku chuckled. “What makes you say th-that?”
Shit.
“It’s just, well…I saw his hoodie on the couch.”
“Oh! That?” Izuku suddenly sounded more confident. “I found it while I was
cleaning up in your room! I left it on the couch so you could take it to him
before school tomorrow.”
“You were in my room!?” Kirishima yelled.
“Uh-huh. You need to get a better hiding spot for your porn.”
“Oh my God, Dad!” Katsuki grinned at the pure disgust in Kirishima’s voice.
“Warn me next time, jeez.I’m gonna go take a longshower now.”
“Night, son,” Izuku said, smiling at the door until it slammed shut. He then
leaned over the side of the bed, and peeked down at Katsuki. He sighed, “I
guess you’re sleeping over tonight…”
“Because that’s something I neverdo,” Katsuki joked facetiously.
Izuku helped him up, and then sheepishly rubbed the back of his neck. “Sorry
about that.”
“I guess it’s fine,” Katsuki replied with a shrug. “I think I like it better
this way.”
“What do you mean?” Izuku quirked his head.
Katsuki smirked, capturing Izuku’s chin between his thumb and forefinger.
“Think about it, Deku,” he crooned. “Now I get to sleep in your bed all night
long.”
Izuku’s face exploded red, and he squeaked a quiet, “Oh.”
Katsuki bit his lip to hold back a chuckle. “God, you’re fucking cute.”
 
 
===============================================================================
 
 
When Katsuki was seventeen, Kirishimafinallygot a girlfriend. A girlfriend he
could talk to. A girlfriend he could kiss. A girlfriend he could hang out with
away from his house.
Kirishima was the kind of best friend that told Katsuki everything.Whenever he
was planning to go on a date with his girlfriend, he would tell Katsuki his
entireschedule for the evening. Every time he said, “Hey, man, Mina invited me
to ‘spend the night,’ if you know what I mean,” Katsuki knew exactly what that
meant. It meant he was going to “spend the night” with Izuku, too.
Mina Ashido was a nice girl. She was kind, bubbly, athletic—pretty much a
perfect match for Kirishima. She was active on the school’s volleyball team,
and was well-known as the neighborhood babysitter. She was called one of the
cutest girls in school, and she had “really nice tits,” as Kirishima liked to
point out. Katsuki didn’t really care if she did or not, but he liked Ashido.
She was cool.
Unfortunately, Mina Ashido was also the kind of person who said whatever was on
her mind.
“How come Bakugou is at your place so much?” she asked one night as she sat at
Kirishima’s dinner table.
Katsuki looked up from where he was in the kitchen, helping Izuku wash dishes
in the sink. Izuku had stilled, listening closely to their conversation.
Kirishima stared at his girlfriend, and then laughed, “ ’Cause he’s my best
friend, of course!”
Ashido pursed her lips. “So then why is he always with your dad?”
Kirishima was silent for a moment, his face gone slack, as if he was processing
this information for the first time in his life. He finally answered,
“Bakugou’s been hanging out with me for so long, he’s like one of the family.
I’m sure Dad feels the same way.”
Izuku squeezed the sponge in his hand, and Katsuki watched a mass of soapy foam
fall into the sink. As it swirled around the drain, Katsuki could see Izuku’s
other hand trembling.
 
 
===============================================================================
 
 
Katsuki sighed into Izuku’s mouth, his calloused fingers carding gently through
dark curls. Izuku’s hands slid up his back, resting on the sharp curves of his
shoulder blades. Their legs shifted against the bed, and Katsuki rocked his
hips forward into Izuku’s. He heard a whimper, soft and hesitant.
“Deku,” Katsuki whispered. “Let’s stop for tonight.”
Izuku pulled back, letting his hands fall to Katsuki’s waist. He stared into
his face, panicked, worried.
“Did I do something wrong?” he asked.
“No, you didn’t.”
“Kacchan…” Izuku said quietly. “Are you…getting tired of me?”
“Fuck, no,” Katsuki snapped, harsher than he intended. He sighed, running a
hand through his hair. “I just…wanna hold you sometimes, you know…?”
He clenched his fist, knowing he sounded stupid. This wasn’t why he started
this. He never meant for it to get to this point. And yet, Katsuki felt so
pathetically touch-starved every time he looked at Izuku. It wasn’t about the
sex anymore. It had stopped being about sex a long time ago.
To his surprise, Izuku nodded.
“I do know,” he replied. “Kacchan… Katsuki, I… I know.”
Neither one of them said a word after that. Katsuki rested his head against
Izuku’s chest for the remainder of the night, and listened to his heart beating
under his ribs. Izuku held his hand, and Katsuki realized for the first time
that they were the same size.
 
 
===============================================================================
 
 
When Katsuki turned eighteen, he didn’t have a party. Instead, Kirishima
invited him over to watch crappy movies and eat pizza. He couldn’t say no to an
offer like that.
Around midnight, Kirishima let out a dramatic yawn, and told Katsuki he was
going to bed. It was rare that Kirishima would go to sleep without him, but
Katsuki considered it a birthday present from the universe. It was more time
for him to spend alone with Izuku.
While he and Kirishima sat on the couch, Izuku had been milling around the
kitchen with a glass of wine. Katsuki had seen him refill it at least twice,
and he had been around Izuku enough times to know when he was feeling tipsy.
This seemed to be one of those times.
Izuku smiled at him, freckled cheeks glowing pink as he set his wine glass
down. He patted the countertop beside him to urge Katsuki forward. He obliged,
and walked to Izuku’s side.
Katsuki tilted his head when he saw Izuku leaning over. His large arms wrapped
around Katsuki’s broad shoulders as they shared a wet, sloppy kiss.
“How’s my birthday boy…?” Izuku hummed, flashing Katsuki the deepest bedroom
eyes he’d ever seen.
Katsuki returned his smile, and said, “Ready for his present.”
“So bad,” Izuku giggled, dragging his index finger along Katsuki’s lip. “I
thought Daddy taught you to be patient.”
“Guess I didn’t learn,” he replied, taking Izuku’s finger into his mouth.
His tongue swirled around the knuckle, and Izuku’s breath hitched. Katsuki
glanced up to see his desperate expression. Izuku’s eyes hazed over as Katsuki
moaned around his finger.
“Kacchan…” Izuku pulled his hand away to kiss him again. Katsuki held him
steady, grasping onto Izuku’s waist to keep him from swaying. He panted softy
between their mouths, “I want you…”
“So do I,” Katsuki breathed. “Want you so bad, Daddy.”
“Don’t call me that tonight,” Izuku said. For a moment, his voice was firm.
“Just call me ‘Izuku.’ Please…”
Katsuki kneaded his fingers into Izuku’s shirt, and nodded. “Alright. Izuku.”
When Katsuki hovered over Izuku on his bed, when he rolled the condom over
Izuku’s dick and slicked it with lube, when he lowered himself, so slow, so
perfect, onto Izuku’s cock, Katsuki called his name, and onlyhis name. Izuku
did the same. That night, there wasn’t anyone else.
There was no “Deku” or “Kacchan,” no teasing or pet names, nothing that could
separate them from the reality of who they were, what they were doing. Katsuki
looked down and saw Izuku, Izuku, so gorgeous and wonderful and his. And Izuku
gazed back and saw Katsuki, Katsuki, someone he’d known for so long, but was
only now seeing for the first time. Someone who was there to fill the hole that
no one else could.
Katsuki came between their stomachs, hunched over Izuku as he finished a few
thrusts later. As they paused to catch their breath, Katsuki started chuckling
in Izuku’s ear.
“What is it?” Izuku asked.
“Just wondering,” Katsuki said, grinning. “How did it feel to fuck an adult for
once?”
Izuku didn’t reply, and instead raised a hand to his chin to stroke it in a
contemplative manner. He hummed, as if deep in thought. Then, he smiled.
“Felt weird,” he laughed.
Katsuki covered his mouth, and snorted. “I thought so, too.”
 
 
===============================================================================
 
 
“Yo, Kirishima. Isn’t that your dad?”
Both Kirishima and Katsuki looked up from the signboard they were painting.
They turned to the classroom door to see Izuku standing just outside, holding
two neatly wrapped bento boxes in his arms. Kirishima sprang up, and Katsuki
followed.
“Dad? What’re you doing here?” he asked, eying the boxes hungrily.
Izuku smiled, and placed each of the wrapped containers in the boys’ hands.
“I knew you’d be staying late to work on your class’s exhibit,” he explained.
“So I brought a little something for you two to eat. I made sure to pack your
favorites, just to keep your energy up.”
“Woah, awesome! Thanks, Dad!” Kirishima said, peeking inside his bento.
“Yeah, thanks,” Katsuki returned. “I was planning on eating out later tonight,
though.”
Katsuki glanced at Izuku, and smirked. Izuku bit his lip. His face flushed.
Before he could reply, a new voice joined in their conversation.
“Good afternoon, Mr. Midoriya,” their homeroom teacher, a young woman with
short hair and large glasses, greeted Izuku at the door. “It’s so nice to see
you! Are you here to help with the culture festival?”
Izuku laughed, “Ah ha, sorry, not this year. Just checking in on my son.”
“Oh, how thoughtful of you!”
“It’s the least I could do, really!”
“You’re such a kind father,” she giggled. “All of the staff here appreciates
your positive attitude!”
“Hey,” Kirishima whispered to Katsuki. “Let’s get back to work.”
Katsuki frowned, brow furrowing as he walked to the back of the classroom. With
each step he took, his classmates’ snickering, gossiping twitters chirped
incessantly in his ears.
“There she goes… Flirting with another hot dad.”
“That’sKirishima’s dad? Damn, he’s tall.”
“Does he work out? His arms are so…wow.”
“Hey, Kirishima!” a female classmate hissed from behind a desk. “Is your dad
single?”
Katsuki ignored the surrounding gasps and giggles from the other girls, and
looked to Kirishima. He watched him slowly run a hand through his bright red
hair.
“Uh…well,” he started, seeming hesitant to continue. His eyes met Katsuki’s for
a split second before snapping away. “I guess…yeah. He is.”
Most of the girls covered their mouths to hold back their surprised, elated
noises. They began whispering excitedly among themselves, ignoring Kirishima’s
uncomfortable expression.
“Hey,” Katsuki said to him. “Let’s sit down and eat.”
Kirishima nodded, and leaned against the far wall of the classroom.
“Um…Bakugou,” he mumbled. “Thanks…”
“For what?”
Kirishima cracked a smile. “For being here.”
As they ate together on the floor, Katsuki was reminded of just how much
Kirishima took after his father. Being near him felt warm. Comforting.
Katsuki turned his gaze to the doorway, and waited until Izuku finally looked
his way again. With a grin and a wave, he was gone.
Katsuki stared into the rice and curry that filled his bento.
He wondered how long this would last.
 
 
===============================================================================
 
 
Katsuki knocked three times, and then rang the doorbell to Kirishima’s house.
Izuku was there in less than ten seconds, panting slightly from what Katsuki
assumed was a mad dash to the door. His usual, dumb smile was plastered on his
face, his shirt sleeves were rolled up to his elbows, and his clothes were
covered in flour. In all the years Katsuki had known him, Izuku never wore a
damn apron. It was infuriating, yet adorable.
“Kacchan,” he sighed, sounding like the moon had been placed at his feet. “Come
in, come in.”
Katsuki nodded, and took off his hoodie to put it up on the empty hanger where
Kirishima’s jacket usually was. He followed Izuku to the kitchen, and asked,
“Is he still out with Ashido?”
“Yes, but they should be here in an hour,” Izuku explained, wiping his hands on
a small towel. “I think the cake should be cool enough to ice.”
“I can take care of it,” Katsuki said, standing next to the large chocolate
cake Izuku had placed on a metal tray.
“That’d be great, thank you. I still need to clean up this disaster of a
kitchen,” he giggled.
While Izuku wiped down the counters and washed out the mixing bowls, Katsuki
spread the thick, white icing back and forth along the top of the cake. His
hand was steady, and his eyes were focused. His body relaxed at the methodical
sound of Izuku turning on the sink, scrubbing with his sponge, and then turning
on the sink again.
When Katsuki began icing the sides of the cake, he heard Izuku humming softly.
He set down the offset spatula, and sucked in a breath.
“I love you.”
Izuku turned to look at him, but Katsuki faced away from the sink. His fists
clenched and unclenched as he held them against the granite countertop.
“I know,” Izuku said. “I’m in love with you, too.”
“I know.” Katsuki nodded. “I just wanted to say it out loud.”
Izuku walked towards Katsuki, his footsteps echoing softly on the smooth, tiled
floor. His fingers ran through the hair on the back of Katsuki’s neck.
“Are you okay?”
“Yeah,” Katsuki grunted, wiping his hand across his face. “Yeah, I’m fine.
Just… I don’t know, I’m—”
“Scared.”
He turned his head, and looked Izuku in the eye. He was staring back at Katsuki
with such compassion, such empathy, it felt like he could crawl inside
Katsuki’s skin and kiss his heart.
“It’s alright, Kacchan,” he whispered. “I’m scared, too.”
“Fuck, don’t be,” Katsuki pleaded, grabbing the front of Izuku’s shirt. “I’ve
always loved you. Even when I was little. Even when I didn’t know it. I know
now… That’s what it always was. I love you so fucking much,Izuku.”
Izuku placed his large, warm hands on Katsuki’s cheeks. Katsuki stared ahead,
and for the first time, he didn’t need to look up to meet Izuku’s gaze.
“You don’t know how happy that makes me, Kacchan,” he murmured, voice breaking
at every other word.
Katsuki held his hands over Izuku’s, and said, “Show me.”
 
 
===============================================================================
 
 
Katsuki’s life ended on the night of his graduation.
Kirishima decided to throw one last, huge party at his house for everyone he
knew, which was almost half of their entire graduating class. As the party went
on throughout the night, Izuku slowly watched as his home became a garbage heap
for the newly minted adults that were no doubt having sex in his pool. Katsuki
stood beside him at the top of the stairs, peering over the balcony at the
chaos beneath them.
“Kids, am I right?” he laughed.
Izuku glanced at him and raised his brow. He grumbled, “Don’t start.”
Katsuki clicked his tongue and whistled, turning around to walk towards
Kirishima’s room.
“What are you doing?” Izuku asked.
“I was thinking about killing some time. Maybe playing a couple games,” he
replied. His hand carefully pushed the handle on Kirishima’s door. “If you can
think of something else to do, I’d loveto hear it.”
Without looking back, Katsuki entered the bedroom, and began flipping through
the pile of video games Kirishima had stacked on a bookshelf. He heard the door
close behind him, quiet footsteps shuffling against the carpet. He smirked. A
pair of arms wrapped around his torso.
Izuku kissed the back of his neck, and mumbled into his skin, “You are
terrible, you know that? Doing something like this in my own son’s room…”
“Hm… We haven’t done anything yet,” Katsuki said. “But if you wantto do
something, then maybe we should move to the bed.”
Izuku hummed, nipping at Katsuki’s ear before letting him go. He hurried to
Kirishima’s bed, which was no longer a bunk bed, but now a single, king-sized
bed placed along the wall that ran adjacent to the door. Izuku threw himself
onto the mattress, and laughed as Katsuki dived on top of him. They wrestled
around for a bit, eventually ending up with their lips locked and their limbs
tangled.
Katsuki slid his hand into Izuku’s pants, palming his cock underneath his boxer
briefs. He watched, enraptured by the way Izuku’s eyes fluttered shut, the way
his chest arched up while his hips rocked forward. Izuku buried a hand in his
wild, dark hair, and curled his bottom lip under his teeth.
“Fuck, Kacchan…” he moaned, knowing he wouldn’t be heard over the noise
downstairs. “Should we…go to my room? To get…you know…”
“Come on, Deku,” Katsuki laughed, reaching down to pull out a box from beneath
Kirishima’s bed. He held a condom packet between his fingers, and waved it in
front of Izuku’s face. “You should know your son isn’t a fucking saint.”
In a haze of stolen kisses and slick fingers, Katsuki soon turned Izuku into a
flustered, muttering mess spread out across his son’s bed. He lifted Izuku’s
ass off the mattress as he slowly thrust his cock deep inside. Katsuki tossed
his head back, letting out a long, satisfied groan. He never got tired of the
feeling of Izuku pullinghim in with his tight, softwarmth.
Katsuki watched in fascination how Izuku’s dick dripped onto his stomach, how
it pulsed and throbbed when he grinded against it. How Izuku’s loose-fitting
polo shirt rode up to his chest, how his biceps flexed each time he gripped the
pillow behind his head. How he squirmed excitedly, moved withKatsuki. How he
moaned his name, moaned Kacchan, Katsuki, more, more, you fuck me so good, so
amazing, you’re amazing, Katsuki, Katsuki, Katsuki—
“Yeah, don’t worry! No one’s even gonna notice we’re—Holy shit!!”
“Oh my fucking God!?”
Katsuki stopped, and turned to the door.
Standing in the threshold, staring straight ahead at the sight of Katsuki
Bakugou plowingIzuku Midoriya’s ass, was Eijirou Kirishima and his girlfriend,
Mina Ashido.
Katsuki glanced at Izuku, whose skin had drained paler than a corpse. Everyone
in the room looked like they wanted nothing more than to curl into themselves
and die.
In that moment, Katsuki Bakugou knew his life had ended.
 
 
===============================================================================
 
 
“…How’s Ashido doing?” Katsuki asked.
Kirishima looked up from where he sat at the dining table, and twirled his
thumbs. “Oh, she’s fine. Probably the most fine out of all of us. When I sent
her home, you know what she said? ‘I knew it! I totally knew it!’ Man, can you
believe her?”
He chuckled loudly, but Katsuki could tell he was playing it up. Kirishima’s
smile quickly vanished, and he cleared his throat.
“How about…Dad?”
“Finally cried himself to sleep,” Katsuki sighed. He leaned back further
against the living room wall. “He says he’s sorry, by the way.”
Kirishima grinned. “How many times?”
“I lost count after thirty.”
“Yeah, that sounds like Dad!” Kirishima laughed. This time it sounded genuine.
He ran a hand through his hair, and scratched at his scalp. “Listen, Bakugou.
The truth is…I’ve known for a while.”
Katsuki folded his arms, glaring at Kirishima wearily. He said nothing, stayed
silent.
“I didn’t tell anyone,I swear,” Kirishima continued. “I never even had any
proof, but I was suspicious. Ever since Mina pointed it out…I did start to
notice how much you would hang around Dad. But I never thought it was a
badthing. In fact, Dad was always happier whenever you were around, and so were
you!”
Katsuki’s feet shuffled, and he nodded.
“I’m not mad at you. Or Dad. I’m happy for you guys—really!” Kirishima quirked
his lips into an awkward smile. “I just…never thought I would find out the
truth by seeing your ass…and my Dad’s ass…on my bed.”
“Sorry,” Katsuki offered, biting his cheek.
“It’s…” Taking a moment, Kirishima paused, and then let out a long sigh.
“…Fine. It’s fine. You guys have sex. And that’s fine. Just fine. Perfectly
fine.”
“Are…you okay?”
“Yes,” Kirishima squeaked. Katsuki watched him gulp down a lump. “Around the
time I started getting suspicious, I had a feeling you two were hooking up.”
Katsuki grimaced. “That obvious, huh?”
Kirishima nodded. “I mean, why do you think I went to bed before you did on
your birthday? I knew you probably had plans to fuck my dad that night.”
Katsuki cocked his head to the side, and shrugged. “…Sort of.”
“Sort of…?”
“Hewas the one who fucked me.”
Kirishima placed his palms together like he was praying, and brought his hands
up in front of his mouth. He sucked in a deep breath through his nose.
“Bakugou. I love you, man. You know this,” he said in a serious tone. “But
please, never tell me the details of your sex life ever again.”
Katsuki snorted, covering his mouth in futility before a hearty laugh burst
from his chest. He doubled over and clutched his stomach, which suddenly hurt
from the strain of laughter after being wound so tight with stress. Kirishima
stood up from where he sat, and ran to his side to rub at his shoulders.
“Man… You’re a fucking messright now, dude.”
Katsuki coughed, “You think I don’t know that?”
“I’m sure you do.”
“Are you being smart with me?”
“Are you being a dad with me?”
They both stopped, and stared at each other. Neither one was sure who would
break first. Kirishima eventually cracked into a grin. Katsuki soon followed.
“Bakugou,” he said. “I’m still your best friend…right?”
Katsuki shook his head, and punched Kirishima in the arm. He smirked.
“Don’t be fucking stupid.”
 
 
===============================================================================
 
 
When Katsuki turned nineteen, he went on his first date with Izuku. It was a
wonderful, new experience for him to be alone with Izuku in public. No
Kirishima by his side, or other chaperones at his back.
It was Katsuki and Izuku. No one else.
“Kacchan!” Izuku gasped, tugging at his shirt. “Look! Penguins! Penguins!”
Katsuki lifted up his sunglasses, and stared at the sign labeled ‘Penguin Hut’
that Izuku was vehemently pointing to. It lead to a hallway that stretched deep
into the aquarium.
“I’m guessing you wanna go there,” Katsuki said.
Izuku nodded his head, and his wide, green eyes twinkled with excitement.
Katsuki was still ever amazed how someone twice his age could look so fucking
cute.
An aquarium employee standing at a booth greeted them before they stepped into
the enclosure.
“Welcome,” she chimed. “You’re in luck! Feeding time will begin in five
minutes. Would you like to purchase a bucket of fish to feed our penguin
friends?”
Izuku slammed a banknote onto the counter, and the employee produced two small
buckets filled with tiny fish. She pushed them forward with a big smile.
“Thank you very much! We hope you and your son enjoy the exhibit!”
As Izuku folded his wallet back into his pocket, he paused.
“Oh…um, h-he’s not…”
“Come on, Deku,” Katsuki grumbled, grabbing the buckets off the counter. “Hurry
up. We’re gonna miss it.”
Izuku sucked in his cheek, and followed Katsuki down the long, dark hallway.
They were both silent for a while. Izuku rubbed a hand up and down his arm
before finally speaking up.
“I’m sorry…” he mumbled. “I should have said something. I should have spoken
up. I shouldn’t have hesitated. Why did I do that? I should have just told her.
I’m not ashamed of you, I promise. I know we don’t have to hide this anymore. I
know that, and I would never—”
“Deku.”
Izuku stopped, looking ahead at Katsuki’s face, glowing a soft, pale blue in
the lights of the hall. He shook his head.
“It doesn’t matter,” he said, unexpectedly calm. “It’s just one person. It
doesn’t matter.”
Katsuki took Izuku’s hand, and placed the handle of one of the buckets into his
palm. He closed Izuku’s fingers around it, squeezing them gently.
Flustered and a bit confused, Izuku searched his expression. Katsuki met his
gaze with strong, tender conviction.
“I’m here with you. That’swhat matters.”
Katsuki could see Izuku’s heart swelling in his chest as he leaned forward to
plant a soft kiss on his lips. When he pulled back, Izuku glowed, too.
As they stood along the railing to the penguin enclosure, tossing down fish for
the birds to gobble up, Izuku began snickering quietly.
“I guess it waskind of funny,” he chuckled.
“Huh?”
Katsuki froze in place, suddenly feeling Izuku’s familiar lips brushing against
his ear.
He whispered, sultry and warm, “She thought I was your daddy.”
“Yeah,” Katsuki laughed, breathless. He turned his head to nuzzle into Izuku’s
cheek. “Wouldn’t that be weird?”
 
 
===============================================================================
 
 
“Uhn…fuck.”
“Hmm…” Izuku purred in his ear. “You’re doing so well, Kacchan.”
Large hands trailed like ropes of fire along his thighs, lifting Katsuki’s hips
higher into the air. He spread his knees and groaned, burying his face deeper
into the pillow on Izuku’s bed. It had been so long, he had forgotten how much
girth Izuku had.
A wordless cry echoed from his lips as Izuku hovered over his back, and
whispered a hoarse, “tight,” into his shoulder blades.
“Deku…” Katsuki gasped. “Deku, Deku, please…”
“Shh, it’s okay,” Izuku soothed, teasing his fingers up Katsuki’s torso. “Such
a good boy, Kacchan… You took Daddy’s cock all the way.”
Katsuki bit his lip, and began grinding his ass back against Izuku. His neck
arched sharply, carrying a deep, wanton moan up through his throat.
Izuku hissed in a breath, digging his nails into Katsuki’s chest.
“Kacchan, don’t rush,” he chided. Katsuki whimpered, and Izuku kissed the back
of his neck. “Be good for Daddy, and let me hear how much you love it.”
Izuku slowly, painfully,pulled most of himself out.
Katsuki clawed at the pillow in his hands. Whining in desperation. Wordlessly
begging for him to come back. Come back, Deku.
Just as slowly, just as carefully, he slid back in. He started to thrust, and
Katsuki screamed.
“Fffuck…! Fuck, fuck, fuck!” his voice thrashed about recklessly. “Fuck, Deku…!
Shit, fuck!”
A loud, clear smackrang within the walls of the bedroom. Katsuki’s ass throbbed
with white-hot intensity.
“Kacchan,” Izuku said, forceful, commanding. “Whatare you supposed to call me?”
Izuku’s palm was sandpaper on his skin as he ran it across the stinging curve
of his rear.
Katsuki shuddered and tensed, but managed to spit out, “D-Daddy…! Daddy!”
Cold fingertips tugged at his nipples, cutting his voice before he could call
out any more. Izuku rolled his hips, and let out a shuddering moan. Katsuki
braced his hands on the bedpost, arching his back into Izuku’s motions.
“Oh, Kacchan…!” Izuku’s cock pulsed and twisted deeper, deeper inside as
Katsuki met each of his thrusts. Izuku wailed, holding him tighter, “Kacchan!
Ah—yes…! Tell Daddy what you want!”
Wild and shameless, Katsuki roared, “God, fuck me! Fuck me!”
He heard Izuku’s breath hitch, and his teeth grazed Katsuki’s shoulder,
threatening to bite. His tongue left a sloppy trail in between the crook of
Katsuki’s neck.
Izuku moaned into his skin, eager, hungry, “Such a good boy… Making those
pretty noises all for me. You’re so good to me, Kaccha—”
Bam. Bam. Bam.
The door to Izuku’s bedroom clattered with the sound of a fist pummeling into
its hardwood surface.
“Oh my God, can you guys please keep it down!?”
They both fell silent. Izuku’s movements halted entirely.
“Mina and I can hear you over the movie we’re watching!” Kirishima’s voice
screeched from the other side of the wall.
“E-Eijirou…!?” Izuku panicked, raising his head. He began shivering. “Oh no. Oh
God. I-I’m sor—”
“Suck it up, Hair-For-Brains!” Katsuki interrupted. “It’s nothing you and
Raccoon Eyes haven’t done yourselves!”
“Huh!? Excuse me, but I’m not fucking her dad!”
Katsuki stretched his neck to shout over his shoulder. “Maybe you should! A
dick in your ass might help you mellow out!”
“Kacchan…!”
“Ugh,you…” Kirishima groaned loudly. “Don’t tell me what you’re doing in
there!”
“Ah, I see! You’re the kinda guy who likes to use your imagination!” Katsuki
returned, making sure Kirishima could hear the smirk on his face.
He reached an arm out behind his back, and twisted his torso around as he
yanked Izuku down by his neck. Katsuki watched his fishbowl eyes grow even
larger the moment their lips smashed together.
It was probably the most disgusting, sloppy kiss they had ever taken part in,
but Katsuki moaned and whined like he was frenching in a porno. Izuku only made
the occasional grunt, obviously too shell-shocked to play along. The moist
noises of their drooling tongues amplified indefinitely once Katsuki sucked
Izuku’s into his mouth.
As Izuku was too distracted and discombobulated to move, Katsuki took it upon
himself to slap his ass against Izuku’s hips.
“Oh, Deku…! Deku!” he yelled in an exaggerated tone. “Your cock is so big! Fuck
me harder, harder! Ah, yes…! Make me your bitch and cum in my ass!”
“Mmn…!” Izuku trembled, kneading his fingers into the bed to stop himself from
returning Katsuki’s thrusts. He glared down at him, and growled, “You are not
being a good boy right now…”
“You know what, forget this. I’m taking Mina out to get ice cream,” Kirishima’s
exhausted voice sighed behind the door. “Maybe the brain freeze can erase this
conversation.”
“Yeah, and you can—” Katsuki tensed as Deku’s tip accidentally brushed against
his sweet spot. He bit his lip, but quickly recovered. “Y-you can think about
your dad’s thick cock creamingmy ass all over the bed sheets!”
“Go to hell, Bakugou!”
Irritated footsteps stomped away from Izuku’s room until they faded down the
stairs.
Izuku smacked Katsuki’s ass, and not in a sexy way this time.
“What the heck was that?” he shrieked.
“What? That?” Katsuki grumbled. “I was teasing him. I do it all the time. He’ll
get over it by tomorrow.”
Izuku’s eyes narrowed, and his lips crooked upwards in disbelief.
“I have never heard you talk to my son like that before.”
“Well, not until recently, no,” Katsuki said, turning himself back around. “But
considering all the times I’ve walked in on him and Ashido, he deserves it.”
Izuku choked on a breath, and Katsuki didn’t need to see the look on his face
to know how disturbed he was by the thought.
“You’ve…walked in in them?”
“ ’Course I have. They usually fuck under the covers, but Ashido has a mouth on
her from what I hear. She talks more than I do.”
“Oh…gosh,” Izuku uttered, sounding somewhat in awe. He cleared his throat and
replied, “I guess Eijirou does take after me in a lot of ways.”
Katsuki snorted, and shook his head into the pillow before him. He chuckled
softly.
“Like you wouldn’t believe.”
 
 
===============================================================================
 
 
Katsuki’s index finger tapped against the handle of the oven. He peeked inside,
eyes narrowing as he observed the thin cake within its aluminum tin.
Deku paced behind him anxiously.
“How long does it have left?”
“One more minute, Deku. Relax.”
“Sorry, sorry,” Izuku sighed, bouncing his heel against the kitchen floor.
“It’s just… This is only my second time trying out this recipe, and I need it
to be ready by tomorrow. I don’t know if the filling will set properly, and
what if the flavors fade during the baking? Does the crust look burnt? I know I
asked that three minutes ago, but a lot can happen in three minutes, so—”
“Relax,” Katsuki said as he turned off the oven. “It’s done.”
Izuku peered over his shoulder, watching with nervous intensity as Katsuki
slowly pulled out the cake tin. He placed it on the cool, granite countertop,
and the two of them stared at the freshly baked confection, lovingly crafted
from Izuku’s modified recipe for crème brûlée cheesecake.
The edges were a golden brown, the middle was light and creamy, and the crust
was firm and crisp. The subtle scent of caramel tickled the air around their
noses, and a pleasant warmth emanated from the surface. Katsuki nodded in
approval.
“Looks good.”
“Looks mean nothing,” Izuku said, holding up a toothpick.
Carefully, he slid it into the center of the cheesecake. After only a few
seconds, he pulled it back out. It was clean.
Izuku beamed.
“It worked,” he sighed in relief.
Katsuki laughed, and smacked Izuku’s shoulder with one of his oven mitts. “Told
you.”
“You know I needed it to be perfect. Even though it’s for charity, the mothers
in this neighborhood are ruthless when it comes to selling their cakes.”
“Psh, whatever. You’ve got cupcakes, muffins, cookies, a chocolate liquor cake,
and now this.” Katsuki gestured to the cheesecake. “I think you’ve already
won.”
“We,” Izuku uttered softly. “We…did this together, Kacchan. I couldn’t have
finished it all without your help.”
Izuku’s smile was the sun and the rain that nurtured Katsuki’s heart. When
their eyes met, Izuku glowed brighter. He reached out to hold Katsuki’s hand.
Their fingers entwined in a dance they had both mastered the steps to long ago.
Katsuki wanted it to last forever.
“Deku, I’m…” he started, squeezing Izuku’s hand. “I’ve been thinking…maybe I
could—I mean… Do you think that I…”
“Yes…?”
Katsuki bit his lip, and let Izuku’s fingers slip out from his own.
“It’s not important,” he assured. “We can talk about it later. We should make
sure all this shit is ready for tomorrow.”
“Oh… Well, you’re right,” Izuku chuckled.
As he turned around to to search the cabinets for an empty cake carrier,
Katsuki watched the tips of Izuku’s ears turn pink. He clenched the oven mitt
in his hand, and tried to reassure himself that he still had time. Next time.
Next time, he would take the first step.
 
 
===============================================================================
 
 
It was Izuku who took the first step. He asked Katsuki one night, curled up
into his chest in the afterglow of sex, “Kacchan, you still haven’t found an
apartment yet, have you?”
“No. Still looking,” Katsuki said, stroking a hand up and down Izuku’s back.
“Well…in that case,” Izuku murmured, almost inaudible. “Why don’t you…move in
with me?”
Katsuki’s hand stopped, and he gripped Izuku’s shoulder. “What…?”
“It’s just…Eijirou will be leaving soon to move in with Mina. It’ll be lonely
here…all by myself. I could use the company.” Izuku’s knees shifted between
Katsuki’s. “And I… I wantyou to live with me, Katsuki.”
He swallowed, gazing down at Izuku’s face, studying it, observing it. Izuku
looked back at him with the most beautiful sincerity he had ever seen.
“Deku,” Katsuki said, taking Izuku’s hand in his. “I’d like that.”
Izuku shot up, and grabbed his face to pull him in for a kiss. Katsuki smiled
into it, and he could feel Izuku giggling around his mouth.
He ran his fingers through Izuku’s sex-tustled hair, and sighed, “I promise. As
soon as I save up enough, I’m gonna make you the happiest piece of shit on
Earth.”
“Kacchan, you already make me so happy,” Izuku said, rolling his cheek into
Katsuki’s shoulder.
“That’s not what I mean,” he whispered.
Izuku slipped out of Katsuki’s hold, and propped himself up on the bed. He
looked down at Katsuki quizzically, as if trying to figure out what he was
going to say next.
Katsuki lifted a hand to Izuku’s face, and caressed his cheek with the back of
his fingers.
“I want to marry you, Izuku.”
Izuku stopped breathing. His eyes went wide.
“I don’t just want to live with you. I want to spend every day with you for the
rest of my goddamn life,” Katsuki said, piercing his claim through Izuku’s
heart.
Izuku mumbled, “Do you mean that…?”
“Of course I fucking do.”
Izuku’s head dropped to his neck, nuzzling into his skin and leaving behind a
small puddle of tears. Katsuki listened to him sniffle and sob for a good
minute.
“What did I do… What did I do to get you?” Izuku cried, wrapping his arms
around Katsuki’s large, solid frame.
Katsuki kissed behind his ear. He smiled. “You made me curry.”
“What?”
“Nothing,” he laughed.
 
 
===============================================================================
 
 
Katsuki poured his morning coffee into one of Izuku’s mugs, and mindlessly
stirred in the tiniest bit of cream. He took a sip, and then stirred in a
little bit more. Izuku walked past him with a plate of toast and breakfast
rolls, and placed a quick kiss to his forehead. Katsuki grunted lethargically.
Kirishima came down the stairs, scratching his stomach as he yawned. He glanced
at the table, and made his way to the refrigerator. After staring inside it for
a couple of minutes, he turned to Katsuki.
“Hey, where’s the butter?” he asked.
Katsuki pointed towards Izuku with his mug. “I already put it on the table.”
“Oh, cool,” Kirishima said, shutting the fridge. “Thanks, Dad.”
Katsuki was about to take another sip of coffee when he froze. Izuku stopped
spreading jam on the piece of toast in his hand, and stared.
Kirishima glanced back and forth at them in confusion. Suddenly, his face
paled.
“Oh my God,” he gasped, slapping a hand over his mouth. “Oh my God, no. No, no,
no, no, no.I did notmean to say that, and you both know it!”
Katsuki chuckled, grasping the counter with both hands to keep from exploding
with laughter. He snorted, “Whatever you say, son.”
“I’m glad you’ve finally accepted it, Eijirou,” Izuku beamed, threading his
fingers and resting his head on top of his hands.
Kirishima’s face burned. He groaned, “I hate this family…”
 
 
===============================================================================
 
 
A heated moan broke free from the back of Izuku’s throat. Katsuki followed a
bead of sweat that trailed along his neck. His hands slid down Katsuki’s waist,
grabbing a fistful of both his ass cheeks. Izuku squeezed and tugged, pulling
Katsuki deeper, thrusting into him harder.
“Fuck,Izuku…” Katsuki panted, clenching his fingers around the bedpost. “If you
want me to go faster, just say so…”
“But you’re so firm, Kacchan,” he giggled. Izuku pinched at his skin. “You’ve
gotten so big now…”
Katsuki chuckled, smirking down at him. “Are you talking back to me, young
man?”
Izuku sucked in his lip, and grinned. “I don’t know. Are you gonna punish me
for it, Daddy?”
“Fuck, yes,I am.”
Izuku squealed and laughed as Katsuki hoisted him up into the air by his
thighs. His legs spread wider, offering his body like he was a meal for Katsuki
to ravageand devour. Katsuki throbbed at the sight of Izuku’s bangs clinging to
his forehead, of his mouth hanging open. Izuku ran his gaze up Katsuki’s chest,
molesting him with his eyes.
Katsuki wet his lips, and pushed his long, hard dick all the wayinto him. “Been
such a bad boy, Deku… Open that ass nice and pretty for me. There we go… So
good and loose for Daddy’s cock.”
“Oh, fuck,Daddy…” Izuku whined, stretching his arms above his head. His neck
craned upward, and a needy, desperate groan passed through his teeth. “Daddy…
It’s so big, Daddy…”
“Fits you perfect, though, right?” Katsuki chuckled, twisting his hips to move
his cock deeper.“You’re Daddy’s perfect little slut, aren’t you, baby boy?
Spreading your legs for me like you can’t wait for my dick. Can’t wait to be
filled with my cum… You want Daddy to stuff you full of it ’til you choke,don’t
you?”
“Holy shit,” Izuku gasped, clawing at his pillow. His body started to go limp
as Katsuki pounded into him. “You’re so fucking good at this…”
“Don’t get lazy on me, Deku,” Katsuki growled in his ear.
He pulled Izuku onto his lap, and both of them winced at the way Izuku clenched
and tightened at the sudden change in position. Taking a few calming breaths,
Katsuki rubbed Izuku’s back, and began a steady movement of slow, shallow
thrusts.
He whispered sweetly, placing a kiss on Izuku’s cheek, “Be a big boy and ride
Daddy’s cock.”
Izuku wrapped his arms around Katsuki’s shoulders, and took a deep breath. He
lifted himself up, slicked back down, and moaned.
“Fuck…fuck,” he panted, fingers trembling as he grasped Katsuki’s skin.
“Come on…” Katsuki urged, stroking his hands down Izuku’s waist, grinding his
cock further into his heat. He breathed in Izuku scent, his musk. His lips
brushed across his neck, and Katsuki murmured, pleaded, “Say Daddy’s name when
you cum, Izuku…”
A muffled cry buried itself within Katsuki’s unkempt hair. Izuku dug his nails
into Katsuki’s back, curling into his hold. He brought Katsuki closer, wanted
to keepKatsuki closer. Never let him go. Keep him and hold him and have him
forever.
“Ah…! Kacchan…” Izuku tensed and shivered, ready to snap, ready to burst. He
tossed his head back, and wailed, “Katsuki…! Katsuki!”
With one final scream that ripped from his chest, Izuku shot his cum between
their stomachs, letting it drip down Katsuki’s abs and onto the sheets below.
Katsuki came a few seconds before him, but pretended to let Izuku think they
finished together.
“Fuck,” Izuku coughed, sprawled over Katsuki like a cat over an armchair. “God,
Katsuki, that was amazing…”
Katsuki scratched his fingers under Izuku’s chin, and chuckled, “Maybe you did
teach me something then, old man.”
“Mn…shut up,” Izuku said, smiling. “I’m not even forty yet, and you know it.”
“Yeah, but you’re still getting grey hairs behind your ears.”
Izuku turned away, and quickly placed a hand over the side of his face. “Damn.
You noticed…”
“Don’t be like that.” Katsuki grabbed Izuku’s wrist, tugging his hand down. He
looked into Izuku’s nervous, flickering eyes, and grinned. “You’d look so
fucking sexy with grey streaks. Can’t believe you dye ’em out.”
“They make me look…old,” Izuku admitted, twirling a finger through his bangs.
Katsuki shrugged. “You areold.”
Izuku moved to get off the bed, but Katsuki pulled him back down.
“I was going to say,” he continued. “That you areold, and you’re going to keep
getting old, but it happens to everyone. You shouldn’t be ashamed of it.”
“But…you…” Izuku sighed, and sucked on his lip. “You’re so young, Kacchan. And
you’re always going to look so muchyounger than me. I’m going to get wrinkles
and bald spots and grey hairs, and when you stand next to me, you’ll look so
handsome and fit… Doesn’t that bother you?”
“No.” Katsuki shook his head. “It never has.”
Izuku’s breath hitched as Katsuki took his hands, rubbing his thumbs gently
over Izuku’s knuckles.
“People can think what they want about us. I never cared one way or another,”
he said, long fingers threading into Izuku’s equally large hands. “What I care
about isyou,Izuku. I want you to be happy… Are you happy?”
Izuku didn’t even hesitate to think.
“I am,” he answered. “I’m so happy…”
“Then fuck everything else. It doesn’t matter.” Katsuki closed his eyes, and
pressed his forehead against Izuku’s. “Do you remember what I said to you? On
our first night?”
He heard Izuku swallow. He gripped Katsuki’s hands tighter.
“Let me take care of you,” Katsuki uttered, quiet and breathless. One of his
hands slid into Izuku’s hair. He sighed, “Let me take care of you, Deku.”
“Kacchan…” Izuku laughed, defeated. “You’d take care of me no matter whatI
said.”
He wiped a thumb across his eye, and gazed down at the boy he made curry for.
The boy he read stories to, whose cuts he patched up, whose homework he
checked. The person he washed dishes with, who made him coffee in the morning,
who listened to him ramble after work.
The person he lovedmore than anyone in the world.
And Katsuki smiled as he looked up at the man who made him curry. The man who
gave him popsicles during the summer, who taught him how to flip a pancake, who
never looked down on him when he made a mistake. The person he sat next to on
the couch, who he helped pick out ties for, who he held close at night.
The person he wanted to spend the rest of his life with.
There was something they shared that couldn’t be explained, but it didn’t need
to be. It was there, and it made them happy. At nineteen years old, Katsuki
Bakugou was happy.
Katsuki let out his own quiet laugh, and replied with a single word.
“Always.”
