Summary
     Katsuki fulfills Izuku's wish to become closer, become connected.
     The first time sets the precedence.
Notes
     aaaannnd we're back on schedule!
     edit: now a new and improved chapter with an illustration from
     LeiLei! (thank you so much omg)
The moment they stepped away from the bus stop, Katsuki looked to Izuku, brow
lifted. “Mom’s working late tonight,” was all he said, was all he had to say.
Izuku squeezed his hand and then let go. Hitching his bag higher on his
shoulder, he said, “Race you.” It was a challenge, commonly thrown from one of
them to the other, only this time it was edged with just a little more urgency
than usual.
Izuku got a head start, but Katsuki caught up with a controlled burst of his
quirk that assisted his vaulting over a fence. Side by side, they ran the whole
way to Katsuki’s home. Their feet slapped the pavement. They panted almost in
unison. They duck and wove around other pedestrians and, when racing across an
intersection, Izuku slid over the hood of a car that screeched to a halt to
avoid hitting them.
He’d landed on his feet, stumbling forward. Katsuki reached back, grabbed him
by the front of his jacket, and hauled him back into the race.
It isn’t about who gets their first because they almost always arrive at the
same time. It’s about the heat that gets caught under their skin, the sweat
that beads on their foreheads and the way they move through the world in
simultaneous, complementary ways.
Katsuki uses his quirk to vault over things while Izuku scrapes and slides by,
wearing thin the fabric on his knees and legs. At one point they hit a brick
wall that wouldn’t be in their way if they stuck to the sidewalks. Katsuki
takes a running jump at it, grasping at familiar handholds as he clambers his
way up the wall. Izuku, on the other hand, runs towards the corner where there
are cans and boxes precariously stacked. They both reach the top of the wall in
a matter of seconds, dropping down onto the grass on the other side with a
tumble to avoid injury.
This time, Katsuki’s hand hits the doorknob first, but it’s Izuku’s shoulder
that lands squarely against the wood. They collapse against Katsuki’s front
door, panting, so close to each other that Katsuki swears he can hear Izuku’s
heartbeat, and grinning. It’s not the same excitement as that which they faced
earlier that day with villains all around and the chance to actually do some
heroic work, but it still burned through their veins like fire licking over dry
kindling.
“I won,” he said, pulling out the key to the door.
Izuku, leaning back against the door, rolled his head onto his shoulder and
grinned at Katsuki, “And what did you win this time, Kacchan?”
Katsuki closed the distance between them as he pushed the key into the lock and
turned it. He turned the knob at the same time that he hooked his arm around
Izuku’s waist, to prevent him from escaping backwards into the house. “Your
ass,” Katsuki smirked, hauling Izuku flush against his chest, “And the rest of
you too, I guess.”
Laughing, Izuku put his arms around Katsuki’s shoulders and hopped up to hook
his legs around Katsuki’s waist too. He was still giggling when he kissed
Katsuki, grinning against his mouth as Katsuki tightened his grip around his
waist and carried him inside.
There, Katsuki shed shoes and jacket with minor difficulty. His bag was dropped
just as unceremoniously as his jacket. Holding Izuku with both hands now,
Katsuki kept kissing him, dragging out eager little sounds as he carried him to
his bedroom.
“Kacchan,” Izuku said breathlessly, “Kacchan.”
Once they made it through that second door, Katuski brought Izuku over to the
bed and dropped him down onto it. Izuku bounced, giddy and giggling, and began
to sit up.
“Down,” Katsuki commanded.
“Kacchan,” Izuku wrinkled his nose as he sat up anyway. “I’m not a dog.”
Katsuki thumped Izuku’s leg with his fist. “You said you trusted me to take
fucking care of you for this. Do you still trust me or are you reneging on that
shit? Huh?”
“I trust you,” Izuku said smiling a little. “But don’t you want me to help?”
“Soon,” Katsuki said. “Right now I just want you to fucking relax for a
second.”
“Alright, alright,” Izuku flopped back down on the bed, letting his arms fall
out to the side. He sighed, even closed his eyes, and lay there still and
quiet. Katsuki watched him silently for a little while before he rubbed his
hands together and crawled onto the bed.
He didn’t have to do much to psyche himself up for what he was about to do. At
least this part he’d done before, sort of. With careful, methodical hands,
Katsuki began to undo Izuku’s uniform. He started with the tie, slipping it
free of its knot. Izuku opened up an eye, peeking up at him as he folded the
red cloth up and set it aside. Katsuki pulled him free of his jacket next,
lifting Izuku by the arm and shoulders as necessary.
The small smile that had played around Izuku’s lips softened into a quiet,
thoughtful expression as he watched Katsuki fold this up and set it aside too.
He took in a breath, opening his mouth, but didn’t speak. Katsuki pressed his
finger over Izuku’s lips. “Don’t,” he said, quiet and firm. “Not yet.”
Izuku huffed out his breath in a sigh and said nothing. Instead, he kissed
Katsuki’s finger and settled back again. Katsuki shifted on the bed, straddling
Izuku’s hips with his knees as he began to unbutton his shirt. He kept his eyes
on his hands, on what he was doing, focusing completely on the act of
undressing Izuku completely.
Katsuki’s knuckles brushed against Izuku’s skin as he pulled back the cloth of
his shirt. Izuku’s body was pliant as he removed this, too, and folded it up.
His breathing was deep, but, occasionally stuttered. Katsuki put his hand flat
over Izuku’s heart. He could feel it beating, feel it racing, under his palm.
Slowly, he slid his hand downwards. Izuku sucked in a breath as Katsuki’s
fingers slid over ribs and his palm dipped against the soft skin of his
abdomen.
Sliding back on the bed, Katsuki gave himself more room to work. Izuku’s belt
and pants were next. Again, Izuku’s breath hitched as Katsuki drew the belt
from the loops and then, slowly, began to slide down Izuku’s pants with his
fingers hooked on the hem.
“Raise your hips for me?” Katsuki murmured. Izuku obeyed. His fingers curled in
the comforter as his pants were slid down his legs. Katsuki climbed off the bed
in the process, leaving Izuku lying there for a minute in nothing but his
underwear. Katsuki folded up his pants and then, gathering the rest of Izuku’s
clothes, dropped them in a folded pile on the floor.
“That defeats the purpose of folding them up, doesn’t it?” Izuku said. His gaze
was riveted to Katsuki, who was fully dressed still. Katsuki leaned over,
bracing one hand on the bed and using the other to pinch the inside of Izuku’s
thigh.
“If you can’t keep your mouth shut when I tell you to, Deku, I’m going to have
to fucking shove something in there. Just wait a goddamn second, will you?
You’re going to ruin the mood.” He pinched again, making Izuku squirm on the
bed.
Izuku pouted up at him. His expression said everything for him, You’re ruining
the mood, Kacchan.
Katsuki pinched him again.
His pout turned into a bitten bottom lip when Katsuki ran a teasing hand up
from Izuku’s thigh to his groin. He rubbed his palm over Izuku’s cloth covered
cock, smirking up at him. Izuku’s hips lifted slightly as Katsuki’s hand moved
away. Behind his bitten lip, Izuku made a soft whimpering sound.
Katsuki teased him a little more, fingertips skating over Izuku’s abdomen
lightly before he peeled back the elastic waistband. Without prompting, Izuku
lifted his hips and made it easier to pull the underwear free. Katsuki tossed
the garment unceremoniously over his shoulder, leaving Izuku with nothing to
cover up his growing erection or the flush that colored him from his cheeks to
his chest.
Under Katsuki’s gaze, Izuku twisted his fingers into the blanket but made no
move to cover up. He looked up at Katsuki, who looked down at him with a hunger
in the back of his mouth that made his stomach clench. Katsuki slid forward
again, crawling across the bed until his knees were at Izuku’s hips.
He bent forward, looming over Izuku, and pressed a soft kiss to his lips.
Izuku’s lashes fluttered as he kissed back. Freeing one hand, Izuku reached up
to Katsuki. His fingers trembled as he touched Katsuki’s cheek. Katsuki held
Izuku’s hand in place with his own and turned his head, kissing Izuku’s palm.
“Do you love me, Izuku?” Katsuki asked with his words muffled by Izuku’s skin.
“Do you really love me?”
 
[Katsuki held Izuku's hand in place with his own]
 
His red eyes burned as they looked down at Izuku, demanding honesty in answer
to his question. It took more effort than he wanted to admit to ask that
question. He had never forgotten the way he’d seen Izuku die for the first
time, driven to it by Katsuki’s very own words. The fear that Izuku held a
grudge for those years of bullying sat deep in the back of Katsuki’s mind and
made him feel undeserving of Izuku’s love- no matter how much he wanted it.
Izuku nodded. Breathless, he whispered, “I do. I promise.” He brought up his
other hand, cupping Katsuki’s other cheek. “I want to be with you forever.” His
fingertips ran back along Katsuki’s jaw and into the hair at the back of his
neck. “Do you love me too?”
Katsuki closed his eyes and let Izuku cradle his head, supporting it in his
hands. With a soft breath let out, warm against Izuku’s palm, Katsuki
whispered, “More than anything.”
“Katsuki,” Izuku whispered. He pulled Katsuki in, littering his jaw with kisses
until Katsuki turned his head and he could kiss him on the lips. “Please,” he
said against Katsuki’s mouth, “I want more.”
“Insatiable,” Katsuki teased, nipping at his lips.
Izuku laughed, dragging his hands through Katsuki’s hair. A shiver ran down
Katsuki’s spine at the nails that scraped his scalp.  Katsuki bit harder before
pulling up and away. He reached down to his own shirt, tugging it up and over
his head in one fluid motion. Unlike Izuku, his skin was marked with small
scars, mostly from shrapnel from his more dangerous explosions, and despite the
fact that the spent an equal amount of time out in the sun, shirtless, Katsuki
was paler than Izuku.
Biting his bottom lip, Izuku reached up, running his hands up from Katsuki’s
waist to his chest. His green eyes followed the path of his hands, pupils wide
but eyes focused on Katsuki, only Katsuki.
Smirking, Katsuki knelt up. He opened his own pants, sliding them and his
underwear down in the same movement. He rocked forward, bracing himself with
one hand as he stripped down to nothing. Izuku laughed quietly as Katsuki had
to lift one leg and kick off his pants. Izuku pulled at Katsuki’s arm, tugging
him in. “C’mon,” he said urgently, “Kacchan…”
“One more thing,” Katsuki said, pulling back, “And don’t pout like that. We are
notfucking doing this without any lube.” He went to the end table and fished
around in the drawer beside his bed. It was plenty full of miscellaneous items,
but Katsuki quickly found what he looking for. He pulled out the container of
lube and returned to Izuku’s arms.
Izuku eagerly welcomed Katsuki’s kisses, putting his arms around Katsuki’s neck
to draw him in and keep him there. Katsuki pressed Izuku down into the
mattress, drawing out soft murmurs of pleasure as he kissed Izuku’s lips and
face. As they kissed, their hands skimmed over warm, moving skin, gripping and
pulling until they were a tangle of arms and legs and breathlessness.
Izuku rolled Katsuki over onto his back, pinning him for several minutes while
he lavished Katsuki’s chest with his mouth. Before he could get farther than
the last rib, though, Katsuki gripped him by the hair to pull him back up to
eye-level and rolled them back over.
At the same time, Katsuki opened the lube, flipping back the cap with his
teeth. He coated his fingers in the slick substance before closing it and
setting it beside them on the bed to free up both hands. Izuku’s watched,
cheeks flushed, mouth open to his panting as Katsuki’s hand moved down between
his legs. He was familiar with the touch of those fingers on his legs and the
way they felt as they probed towards his entrance. This was something they’d
practiced a lot since that first time up on the mountain.
Only somehow, this time, it was more intense than before. Izuku’s fingers dug
into the skin of Katsuki’s shoulders tight enough to bruise, but it wasn’t pain
that he was fighting against. Katsuki grunted at the tight grip but didn’t
otherwise complain.
“Lift your leg a bit more,” Katsuki said against Izuku’s ear, “Yeah. That’s
it.” He kissed the lobe as Izuku hiked up a leg, giving Katsuki better access
to his ass with his hand. “C’mon, Deku, don’t fall apart on me now. This is
only the beginning.”
“‘M not falling apart,” Izuku huffed back. “I’m melting.” His eyes were closed
again when Katsuki lifted his head enough to see his face. “Your hands feel so
good.”
Katsuki rolled his eyes and bit Izuku’s jaw. “Stupid Deku,” he muttered, even
as he twisted his hand and pushed in another finger. He watched with half
closed eyes as Izuku squirmed beneath him, squirmed becauseof him, whimpering
and gasping softly.
Every breath Izuku pulled into his lungs was stuttered with gasps and moans as
Katsuki worked his fingers in deeper, spreading them to stretch Izuku. Katsuki
could feel Izuku’s chest  rising and falling against his own, could feel his
breath over his ear as he sucked hickeys down Izuku’s neck.
Izuku’s hips rolled up in time with the push of Katsuki’s fingers. It hadn’t
taken him long to learn how to fuck himself on Katsuki’s fingers once they
started doing this more regularly. Only this time, Katsuki kept adding more
fingers, kept pushing and stretching longer than he usually did.
It quickly got to the point where Katsuki had to kneel up to prevent Izuku from
grinding up against him with his cock. Any more friction for either one of them
and they’d end up frotting instead of fucking. Before, that would have been
enough, but Izuku had asked Katsuki for more and more is what he would give.
He applied more lubricant to his fingers, pushing in, searching for Izuku’s
prostate and finding it. Izuku’s moan rose to a sharp cry as Katsuki pressed
against the sensitive spot. Without Katsuki close enough to grab, Izuku’s
fingers twisted in cloth, in his own dark hair, moved restlessly towards
Katsuki, and seemed out of Izuku’s control.
Most of his body seemed that way, in fact. As Katsuki looked down at Izuku,
slowly pulling his fingers out for the last time, he took in the sight of
Izuku. His mouth was slack, open to his panting, his mindless noises. His eyes
were closed more often than not and bleary when open. Sweat dampened the hair
at his temples and made his skin shine. The red hickeys marred his skin around
his jaw and throat, showing where Katsuki had littered him with marks.
Further down, Izuku’s chest moved with his shallow breathing. His nipples were
perky and begging to be touched as Katsuki just hadn’t had the time to give
them attention yet. Izuku’s hips squirmed as he opened his legs wider in
invitation. It was clear that he missed the feeling of Katsuki’s fingers. It
was even more clear how close to the edge Katsuki’s fingers had driven him,
considering the state of his dripping cock.
There was only one thing missing.
“Look at me,” Katsuki said. He spoke as he applied lube to his own cock.
Izuku shuddered all over at the sound of Katsuki’s voice. His head rolled and
his eyes opened and he looked down at Katsuki.
Katsuki licked his lips. A tingle ran down his spine as he met Izuku’s gaze. He
couldn’t help but square his shoulders a little, to lift his chin, to show off
how fucking in control he was, even if it was just a show. His hands shook
slightly even as he reached out to Izuku’s legs and lifted them up, sliding him
across the blankets and closer to himself.
He was the one who positioned Izuku, who put one of Izuku’s knees over his
shoulder, who, at last, pushed inside.
“Fuck. Fuck.”Katsuki panted. His hips thrust shallowly, moving impulsively. His
fingers dug into the side of Izuku’s knee and he fought to deepen his
breathing, to get control of himself. Beneath him, Izuku lifted his hips off
the bed and tried to pull him in more. Katsuki grunted and thrust again,
purposefully this time.
The deeper he sank, the higher Izuku’s spine arched off the bed until Katsuki
was buried in Izuku. It was hotter than he’d imagined, and tighter too. Katsuki
rocked against Izuku, not quite pulling out. His eyes flicked up to meet
Izuku’s and he grinned when he saw Izuku’s face.
Flushed cheeks, teeth digging into his bottom lip so hard Katsuki was afraid
he’d bite through it, Izuku didn’t look away from Katsuki for longer than it
took to blink. Katsuki rewarded that obedience, that devotion, with a kiss to
the side of Izuku’s leg and another shallow thrust.
“K-kacchan,” Izuku panted out. He pushed back with his hips, grinding against
Katsuki eagerly. “Please?”
With his other hand holding Izuku’s leg out, giving Katsuki all the room he
needed. Katsuki licked his lips, got his knees under himself and began to
thrust seriously.
All of the reading and videos that Katsuki had seen didn’t do the feeling of
actually fucking Izuku any justice at all. He had thought himself prepared for
the feeling of heat, for the way Izuku clenched around him, just because he’d
used his hands in the same place before. He hadn’t had a clue how it really
felt.
Sweat ran down Katsuki’s spine as he kept thrusting. He kept having to fix his
grip on Izuku’s legs as his hands slipped. There was more going on than Katsuki
had expected and every part of it added to his arousal until it was
overwhelming.
Swear words and grunts alike spilled from Katsuki’s lips as he bent forward,
putting more force into his hips. Izuku met him for most thrusts, the heel of
one foot urging Katsuki on like a spur drove a horse to run faster. Whenever
Izuku’s eyes closed, Katsuki would growl out “Look at me”and slow down until he
was obeyed.
Under that green gaze, Katsuki felt as though he could do anything. Even when
Izuku tightened around him, even when each thrust made Izuku shudder, even when
Katsuki had to dig his fingers into Izuku’s skin, breathe deep and grit his
teeth to keep from coming first, coming too soon; Katsuki was confident. As
long as he had Izuku’s attention, Katsuki was invulnerable- even to his own
human weakness.
Izuku sobbed out in his pleasure. Blood trickled down his chin from where he’d
bitten his bottom lip. Katsuki could tell it was his end by the way he arched
his back and lifted his chin, fully exposing his seemingly vulnerable body and
throat.
Impulsively, Katsuki let go of one of Izuku’s legs and reached up for his neck.
He could get a decent grip on it if he lifted Izuku’s hips, shifting the angle
he thrust in at. All he could do with one hand was cut off Izuku’s airway, but
that was enough to make Izuku clench harder around Katsuki’s cock. Katsuki
hissed between his teeth, nails and fingertips digging into Izuku’s skin to
leave bruises and crescent shaped indents behind.
Izuku choked out something unintelligible as he came, his breath unable to
escape because of Katsuki’s hand. His whole body was tense as his cum
splattered up against Katsuki’s chest and stomach and down onto himself.
“Shit,” Katsuki gasped out as Izuku’s body didn’t quite relax. Even as his
climax faded, it still was instinctively tense from the lack of air. Izuku
didn’t struggle against Katsuki, only looked up at him with wide green eyes,
his hand over Katsuki’s wrist. Izuku held Katsuki’s hand there, fingers
pressing down, not pulling away. Katsuki thrust in and out, movements barely
controlled now.
“Gonna,” Katsuki said, “I’m gonna- Fuck- Deku-” Katsuki’s eyes closed as he
buried himself in deep. “Izuku,”he breathed out as he came.


 
 
Katsuki took in a shuddering breath, slowly releasing Izuku’s throat. Beneath
him, he heard Izuku start to gasp and gulp for air, shaking from the lack of
it. Still, instead of pushing Katsuki away, Izuku pulled him in to hold him in
his arms.
His cock slid out with a slick sound that was nearly as vulgar as the words as
he whispered into Izuku’s ear, his breath hot on Izuku’s skin. “I’m going to
fuck you every goddamn day for the rest of our fucking lives, Deku. You hear
me? Your ass is mine.”
Izuku turned his head and met Katsuki’s lips in a kiss. He mumbled his assent
into the kiss, his words slurring together in his exhaustion. Their kiss was
sloppy and ended when Katsuki sucked the blood from Izuku’s lower lip, his
tongue rolling over Izuku’s chin and making him giggle.
Finding one of Katsuki’s hands, Izuku tangled their fingers together and smiled
at him. “I love you too, Kacchan.”
Katsuki huffed out his breath and tucked his face against Izuku’s neck to doze.
He’d rest for a while and then get up to clean them both off, but, for now, he
wanted nothing more than to bask in the warmth of Izuku’s love.
