Chapter Text
Despite what most people dubbed him as, Bakugou Katsuki, Pro-Hero Dynamight, isn't just proud, loud, and as his fans call him, a gremlin.
He's a hero, first and foremost. Well, hero student, still. But it's only two months before their graduation, and Katsuki will be graduating as one of the Big Three of their batch. He's eighty percent of the time on the streets already, rather than in classrooms, doing patrols and missions as one of Endevour’s best sidekicks.
He's a friend to his classmates, no matter how many times he denies it. Years of hero school and doing death-defying school events and assignments (i.e Summer when he got kidnapped, Second Term when they almost turned the hero society upside down, you know, normal things) made him mature and soft, and sooner he found himself worrying about his classmates, one of most frequent is his best friend, stupid Izuku.
And most importantly, he's a son to his parents. Despite gagging at the thought of showing appreciation through words, and being sweet and affectionate to his parents, Katsuki cannot deny that he is still a son to his parents. And the moment Burnin told him that he was one of the Hero Rookies of the Year that will receive an award, his first thought was to call his mom and share the good news.
Mitsuki, his mom, as loud and as proud as he is, almost exploded his eardrums with her squeal the moment she heard the news. And it even turned an octave higher when Katsuki told her that he'll bring her and Masaru, his dad, to P-Island for the ceremony.
(P-Island is one of the small private islands located at I-Island. Katsuki doesn't fucking know how an island is inside an island, don't fucking ask him.)
Katsuki was one of the youngest achievers of the award for this year, even stupid Izuku didn’t get the award. Despite Izuku and Shoto’s teasing, Katsuki’s grin never vanished from his face, he knew he deserved that award and he’ll show everyone how happy he is with it.
Katsuki didn’t know when everything turned to shit.
Is it the moment they arrived at the island, with his mom dragging him everywhere, his dad following closely behind them, and someone bumping into him, and despite the offender not saying sorry, Katsuki didn’t glare, unlike what that bystander did to him?
Is it the moment he let his guard down, let his fans take his pictures, ask for his signature, letting his fame get to his head that he somehow missed how someone in the crowd is looking at him with malice, with want, and with a grudge?
Or is it the moment his suite room‘s doorbell rang, and he let the crew wheel his ordered food, not missing a single moment to drink the juice and thank the crew, missing the hungry grin of someone in the corridor?
Or maybe it was that moment he got out of the shower, a grin still plastered on his face, checking his suit one last time before noticing the envelope above the room service tray with a simple “Congratulations, Dynamight” scrawled messily in it.
It’s probably the moment he opened the envelope, explosions going off in his hands but not from his quirk. And then, the building was shaking, more explosions were going off, and Katsuki was feeling lightheaded, having been thrown off from where he stood to the door after the envelope exploded in his face.
His ears were ringing, and there were shouts and sirens around him, cries of people looking for other people. Someone was shrieking far away, and it was probably the hero in him, but he tried to stand up, his mind full of find them, save them, move.
But before he could take another step, there was more shaking, Katsuki felt more than see, the moment the ceiling collapsed above him.
When he wakes up again, he’s welcomed by the white ceiling, the sound of a heartbeat monitor, and the smell of the antiseptic. His whole body is aching, and he’s pretty sure there’s a cast on his neck, so it’s pretty fucking hard to move on his own.
He still tried to, of course. And he fucking sat up on his own, of course.
His shoulders sag, feeling weary. He curses under his breath. The events of the night of the awarding flashed before his eyes. He moved again before he could think twice, his mind going to his parents, worried about what happened to them that night.
But before he could step away from his cot, the door opens, and he’s come face to face with Detective Tsukauchi.
“Detective?” Katsuki murmurs, his voice sounds very familiar but unfamiliar under his own command.
“Bakugou-san,” the detective started, before Katsuki could even say another word. Katsuki frowns, better used to Tsukauchi’s ‘Gremlin-sama’, rather than this formality. “I’m so glad to see you're okay.” The detective gestures to the other officer beside him, probably to get a nurse, before addressing Katsuki once more, “I know you’re still recuperating, but I needed to ask a few questions regarding Katsuki.”
Katsuki’s frown deepens, “K-Katsuki?”
“Yes, ma’am. Do you remember anyone, other than the villains he apprehended before, to hold a grudge against your son?” the detective explains, “We’re still looking for the terrorist attack angle, but after seeing the footage, we–”
“Wait, Detective.” Katsuki says, urgent. What is he saying? Isn’t he in front of him? And did the detective call him ‘ma’am’?? “Explain it to me in simple terms, whatever do you mean?”
The detective’s eyes widened, eyes searching Katsuki’s person, before saying, “Bakugou-san, do you remember anything from the attack last night?”
Before Katsuki could answer, the door opens once more, this time, his angry father coming inside. “Detective, please.” he says, going in front of Katsuki as if shielding him from the officers. “I told you to give us some time to mourn for our loss. Why must you do this instant?”
Mourn?
“I know, and tens and thousands of heroes and civilians are too. Losing Dynamight is a big scar to society, and we must know what happened to him, as soon as possible.” the detective argues back.
Losing… who?
“Stop,” Katsuki announces before the detective can argue some more. “Explain to me what is happening. Lost Dynamight? How?! I… I am…”
“Oh, honey…” Masaru, his dad, sadly turns to Katsuki. The older envelopes him in a hug, and with tears in his eyes, he says, “I’m so sorry, Katsuki is gone… Our boy is dead, Mitsuki… gone.”
To say Katsuki went into hysterics is an understatement. Or he’s probably gone crazy.
The detective, together with his father, explained what happened. They are currently looking into two angles:
One, what happened at P-Island the night of the awarding ceremony is a terrorist attack. Knowing well that the island would be full of rookie heroes, and attacking it would mean disabling a part of the hero society.
Two, it was an attack from someone with a personal grudge against Katsuki and is targeting him directly. Recovered footage from the island confirmed that the first explosion happened at the building Katsuki and his parents are staying in. Further investigations showed that the origin of the explosion came from where Katsuki was staying.
Eyewitnesses were saying they saw two men loitering on Katsuki's floor, one of which had contact with the room service crew that Katsuki last saw. The service crew survived and already confessed that he was paid a hefty amount to put something in Katsuki’s drink that night. The vial and the glass were all destroyed in the explosions, so they weren’t able to confirm the origin of whatever Katsuki consumed that night. The crew said he didn't know what it was, he was just tasked to put it in Katsuki’s drink for some money.
They say there's no way Katsuki is alive after the building collapsed. Many people are now buried under the rubble and there’s less hope to have them rescued alive.
That information only added salt to his wounds, knowing they were mourning for the wrong person. Looking for the wrong person.
Katsuki cannot even mourn for his mom if that is the case.
Katsuki cannot even begin to explain that he is who they think his mom is. Everyone, including his dad, believes he is Mitsuki. His confusion made them think he was having a trauma response, forgetting some information and events.
And, looking in the mirror only made everything futile.
His mom’s familiar face stares back at him. Her soft face, plump cheeks, and expressive eyes that Katsuki genetically inherited from her. His short hair, having been cut off due to the operation, made him look exactly like her.
They always say he looks exactly like her, that if Katsuki were a girl, he'd be his mom's little twin. With her ferocity and quirky attitude.
But Katsuki knows, it’s him, it’s his body.
His quirk beats under his skin with such familiarity, the quirk manifesting the way he intended it to be: loud, bright, wonderful, and warm.
But who would believe him? Is this a quirk? Or is this what happens with whatever the crew put in his drink? He can’t even start investigating, because the vial would be ashes by now, and with his mom’s face in his face, he won’t be permitted to question the crew.
Before Katsuki knew it, the week passed by in a blur. They held a closed reception for his own death, and an open-to-public one, as well. Many people came: family, friends, his classmates from Class 3-A, heroes he worked with, heroes who know him in passing, civilians he saved before, mentors and teachers from UA, and people who admired him came and mourned for him.
Even stupid Izuku came to him, hugging him and saying "Auntie, I'm so sorry. Kacchan is…. Kacchan is…." before turning into sobs.
Katsuki remained silent in one space, looking at his own face at the altar, hearing people cry for him and whisper well wishes at him, as if he were his mom, Mitsuki.
With the dread of losing his mom, and suddenly feeling so helpless, Katsuki could only lock himself in his room once everything is done, crying and mourning for his mother he can’t even give a proper burial for.
Hours of crying made him fall asleep in his bed, too tired emotionally and physically to hear the door open as Masaru comes in, whispering “I miss him, too, honey.” at him, placing a chaste kiss on the side of his head, before leaving him once more.
He wakes up hours later, the clock letting him know it’s two in the morning. He groans, the reality hitting him once more.
Before he could cry and let himself be weak again, he stands up, determined. At least his Dad, Masaru, deserves to know what happened to his partner, to his wife, to the girl he promised life and death to.
Katsuki exits his room, looking around their dark home. Never did their home feel so bare and cold and dark, is this what happens when you lose someone? Everything feels empty, void, just because you know you wouldn’t feel their presence again.
He sighs and wonders for a second if his dad is still awake, and if he should just talk to him tomorrow morning. But, he figured, he might lose this determination come the morning.
He has to do this now.
Then, he heard a sob.
The almost silent cries brought him to the seating area. There, he found his father, broken, mourning, and crying. The moonlight that shines through their window gives his father a very gloomy silhouette. You can feel sadness radiating from him, his cries were too quiet, and if Katsuki wasn’t trained to be a hero, he wouldn’t have picked on it.
In front of Masaru was a table full of empty beer bottles, cluttered all around him and the table itself. He was on the sofa, leaning his head on the headrest, looking up at the ceiling as he let his tears run down the side of his face.
Katsuki never saw his father so broken.
His murmur of “Katsuki… my boy…” was what made Katsuki run to him. He envelopes his father in a hug from behind, tucking his head on his father’s neck. His tears and sobs came in, and he brakes some more because he sounds exactly like his mom does.
“I’m sorry,” Katsuki sobs, and he wonders if he’s saying sorry because Masaru lost Mitsuki, or if it’s because he’s mourning for the wrong person. Or maybe he's saying sorry because he’s the reason his father looks so broken.
They remained there, with Katsuki hugging Masaru from behind, crying and sharing their grief and sadness with no words at all. It took some time, more minutes than Katsuki could count with his fingers before he leaned away.
He gulps, gathering more courage, then with a stuttering voice, he started, “I… Dad, I am…”
Before Katsuki could finish his confession, Masaru’s right hand reached out to his nape, dragging him closer. And before he could blink, he felt his father’s lips on his.
Katsuki’s first reaction was to shove his father away, shrieking quietly into the kiss. He didn’t know if it was another side effect of whatever he drank one week ago because the strength he was so proud of proved no worth to his drunk father.
Katsuki, in his eighteen years of life, has never been kissed. It is probably because he’s too focused on his goal to be a hero, that the normalcy of what teenagers should experience, passed by him like a leaf on the wind.
Katsuki’s searched about it before, curiosity getting the best of him. But that was the extent of it, searching for it, reading or watching about it. He never experienced it. The most physical touch he experienced that is bordering on this department was during the graduation ball, two months ago, when he danced with all the girls in their class and he had to hold their hand. And that was only because the girls required all the boys to do that.
Katsuki pushes through, leaning away enough to say, “Fuck! What are you–” but then, his father was to his face again, swallowing his retorts.
And then, Katsuki was lost.
He felt himself melt into the kiss, leaning to the sofa, hands gripping beside his father’s face, scratching the leather, letting his father take the lead. His father groans into the kiss, Katsuki’s mouth swallowing the sound. The hand on his nape is firm, pressing him to his father’s face, as the older’s kisses get more daring and heated.
Katsuki cannot help but moan, head tilting to the right, giving his father more access. Masaru groans appreciatively, his tongue searching his son’s mouth, their saliva mixing, tasting each other.
Katsuki can feel himself tip-toe, body bending to the shape of the sofa as his father discovers a part of him no one has ever ventured. He moans some more, left hand finding purchase to his father’s shirt, gripping the cloth tightly.
His father lets go of him, their eyes meeting, “Let’s find Katsuki again, honey.” his father says, almost delusional.
Or maybe, it was Katsuki who is delusional. He’s staring at his father’s lips like a hungry beast, waiting to pounce on it. The words didn’t register in his brain, only the fact that his father called him honey, or maybe it was because his father called his name.
Why is he letting this happen? Is it because it's his first time? Is it because he's discovering something new, and letting his naive curious self feed on his curiosity? Or is it because they both lost someone dear to them and they found solace in the heat of each other? Is that how his father feels? Is that how he feels?
He should be shouting at his dad, should be punching the living daylights out of him, and explaining who he really is and who they should be mourning for.
But Katsuki only watched, and let everything happen.
Katsuki, with lidded eyes, watches in anticipation as his father stands up, rounds up their sofa, and walks up to him. He let his father take his right hand and dragged him to his parent’s room. He didn’t even question it, and only let his father lead him inside.
He wondered for a second if kisses make you drunk because he was one hundred percent sure he was not sober for how he let his father guide him to the center edge of the bed, and sat him there, before letting Masaru kiss him again.
His father is a fucking good kisser. Best, even.
Masaru's touch isn’t kind, his hold is tight on Katsuki’s shoulder, probably bruising, as his left hand started venturing into Katsuki's body, slipping into Katsuki’s shirt, feeling him up. From his hips to his lean stomach, to his unfamiliar breasts.
Katsuki yelps, leaning away slightly. His father didn't take offense. He even saw his father smirk, before pushing his shoulder to let him lie on the bed, then gropes a handful of Katsuki’s left breast, massaging the mound slightly, testing it, spreading his fingers, then groping once more. Katsuki moans, body arching slightly, and then his father's fingers find Katsuki’s nipple and start pinching it, smirk still present.
Katsuki, in his defense, never knew what was a necessity for women. He never saw any woman naked. He’s not like his good-for-nothing grape head classmate, so Katsuki didn’t know that Masaru’s smirk was for his lack of bra, giving his father all access.
(Yes, Katsuki attended his burial with no bra whatsoever, he never thought of it. And having been situated in one space, no one knows. Masaru, probably, noticing, once or twice, but his mind is too empty to be horny at that time.)
Katsuki lets his father take off his shirt, followed by his pants, and then his boxers. Masaru’s too drunk to question why Katsuki is wearing a boxer rather than a panty, at this point. All Masaru was interested in was the cunt in front of him, shiny and already leaking pre-cum.
Katsuki sinks into the bed, suddenly feeling shy. He presses his knees together, safekeeping the organ he’s not very familiar with.
“Don’t do that, baby,” his father murmurs, crawling to him to the bed. Katsuki’s leg parted like the red sea the moment Masaru started caressing his legs, up to his inner thigh, until he reached the edge of his cunt, thumb circling the sex, teasing.
Katsuki moans, “No- hnggh, please…”
Masaru smirks, and then suddenly, Katsuki’s legs were being pulled downward, until Katsuki felt his father’s clothed hard-on pressing on his soaking, wet cunt.
There was a moment of clarity.
Katsuki shouldn’t let this happen. This is his father, who thinks he is his mother. His father who raised him, fed him, and clothed him.
His father, who kissed him, touched him, discovered him, and undressed him.
Fuck, Katsuki should shove him away, they haven’t even breached that line yet, they could still start anew, learn what really happened and mourn for Mitsuki and get back to their usual life. He shouldn’t let his father do this.
Fuck.
Fuck. Fuck it.
Fuck, he should stop this.
This is wrong.
This is so wrong.
Wrong. Wrong. Wrong.
But, how can something so wrong, feel this right?
How can Masaru’s touch feel so warm in his skin, almost precious and caring? How can his father’s kisses make him feel so light-headed, breathless, and whining for more?
And how can Masaru fit him so well, when it’s so wrong?
Before Katsuki could let that tiny rationality win, he heard a zip of a zipper, then something hard and long smacked his sensitive and gushing cunt. He moans, his hips moving on their own, meeting his father’s cock rubbing into him, seeking friction.
“Fuck, Mitsuki, you’re so wet.” Masaru moans, grinding together with Katsuki. The head of his cock catching on the edge of Katsuki’s cunt.
“No!” Katsuki begs, head thrashing as he sits up, arms snaking to his father’s nape, their eyes meeting, nose touching, lips mere inches away. “Please. Don’t say my name,”
Masaru hums, hands easily finding purchase to Katsuki’s hips, moving up and down, as he caresses the latter’s hips, thumbing Katsuki’s stomach, mind going haywire, imagining it rounded, full, and probably full of life. Masaru wonders if he should name their child Katsuki once more, just so they could have their precious son back.
“What should I call you then, hm?” he asks, pressing a chase kiss to Katsuki’s lips. His body is still moving, rubbing his cock on Katsuki’s cunt, up, down, up, down , his pace fastens, body pressing roughly to Katsuki, letting the younger feel him and crave for him.
“Baby?” A moan.
“Honey?” A whine.
“Love.”
Katsuki’s eyes widen, and he cums, soaking the sheets.
He sags in relief, head falling to Masaru’s shoulder, panting. The older chuckles, hands snaking behind him, caressing his naked back sensually, he can feel the hair on his body stiffens, giving him goosebumps.
He’s fucking sensitive, and this old man is enjoying it.
“You like me calling you Love, huh?” he says, voice husky and almost whisper-like, lips pressed on Katsuki’s ears. There was a pause, and then Masaru licks, tongue swiping Katsuki’s ears, letting the younger let out another tired moan.
“Fuck– hnggh, stop– I’m… hah– I’m…” he stutters, suddenly at a loss for words. His body gave access to his father, neck tilting to the right, letting his father mark him, leaving bite marks everyone could see, sucking kisses on his skin that would probably bruise for days.
Katsuki scratches Masaru’s back, the shirt preventing him from putting marks on his father’s body. Masaru, feeling Katsuki’s frustration, hums, before leaning away, and hastily taking off his shirt.
His father might be twice his age, but his body is built. There are no abs, but he’s lean and fit and fuck, he’s sweating and Katsuki can feel his cunt quicker with the thought that he’s the one that made his father so sweaty.
Katsuki threw himself to his father some more, fingers scratching at once, leaving marks. His head tucked in his father’s neck, leaving chase kisses in his wake, tasting his father’s skin.
They fell on the bed together, with Masaru on top of Katsuki.
Masaru chuckles, “You’re so eager, my Love.” he says, continuing his marking on Katsuki’s body.
Soon, his father’s hands and kisses reached his breast, something so unfamiliar for Katsuki, but felt so good. Masaru massages the right, fingers pinching the bud as his lips start ravaging the left, biting the bud, stretching as if something would come out of it.
Masaru cannot wait for when Katsuki starts lactating for their kid, breast heavy and round and milk so sweet. He let Katsuki feel his eagerness, biting harder making Katsuki let out a cry, “Fuck! Hnnngh– more!”
Katsuki’s body is arching beautifully, seeking more. Masaru smirks once more, hand already traveling south, finger feeling up Katsuki’s soaking wet cunt, inserting one, then two, rejoicing in the sounds permeating their bedroom.
Once three fingers are in, Masaru leans away again, pressing Katsuki to the bed, his Love's sprawled beautifully on their bed. His shoulders and breasts are full of marks, branding him as Masaru's. His breasts are full of bite marks, nipples stretched and red.
And his cunt, soaking juices to Masaru's hand, the slide of his fingers easy.
He meets Katsuki’s eyes, and Katsuki watches as he slowly descends, eyes still on each other, as he swipes his tongue to Katsuki’s sinful cunt, tasting his sweet precum.
It was a different kind of good.
Katsuki’s eyes roll to the back of his head, lips parted in an o, saliva dripping, and body arching, toe-curling, hands gripping their sheets.
He looks so fucking beautiful like this.
His father’s tongue found his entrance, and together with his fingers, he stretched him out, tongue fucking Katsuki’s cunt with practice, pressing on the right places, tongue skillfully tasting inside.
He never knew he could feel something so good, fuck. Is this how all women feel? Is this why there are women who like being women, feeling so good all the time like this?
Fuck, for a moment, Katsuki doesn’t mind.
He doesn’t mind if he’s in a woman’s body. He doesn’t mind if he couldn’t get back to being Katsuki, pro-hero Dynamight. He doesn’t mind the world thinking Bakugou Katsuki no longer exists.
He doesn’t mind if his father thinks he is his mother.
He doesn’t mind.
As long as he could feel this good. His father’s fingers and tongue were inside him, reaching places he never knew existed.
Fuck, he doesn’t mind at all.
But then, his father pulls out with a pop, and Katsuki cries, “No– hnngh!”
His father’s hands caressed his thighs and legs as if teasing him. And then, he snaps Katsuki, folding the younger in half. Katsuki panics, he never knew a person’s body can bend in half. And fuck, everything is visible, his father can see everything, and what the fuck, why does being in this position feels so embarrassing but so good at the same time??
And his father has the audacity to smirk. And soon, Katsuki found out why, because before a moment passed, something hard pressed on the entrance of his cunt, and this time it wasn’t a finger or his father’s tongue. “Don’t worry, love,”
It was his father’s cock, at the entrance of Katsuki’s cunt.
Katsuki was filled with delicious dismay.
Fuck, he’s letting it happen.
He can feel his cunt opening for his father, welcoming him in. He can feel it breaching inch by inch, making sure Katsuki can feel every vein and crevice of his father’s cock, molding his cunt to its shape.
His father's cock is hung, girthy and long. It's a fucking monster. And Katsuki would embarrassingly admit that his father's cock is bigger and longer than his own when he was in his original body.
Shit, Katsuki likes it so much.
He thought the first time would hurt, but it only felt good.
So good.
He'll give up everything to his father.
And fuck, how worth it will it be.
He can be his father's cocksleeve for all he cares, if he could feel this good, he doesn’t mind it at all.
He'll sheath himself to his father's cock, keep him warm and hard and ejaculating. Fuck it, he'll let his father use him.
Make him his toy.
He can feel himself cumming around his own father’s cock, the joy of being filled for the first time is too much for him to bear. Katsuki moans, as his father bottoms out, the head of his cock seating snuggly inside him, the tip knocking on something firm and hard inside.
He was filled with more delicious dismay. His father reached the entrance of his womb.
Masaru then started moving, shallow at first, as if he was learning all of Katsuki’s special places. Katsuki's moans were melodious, a song to Masaru's ears as he fucks Katsuki's cunt, the squelching sound was sinful and it makes Katsuki embarrassed.
Then, Masaru hit a special spot.
Katsuki shouts, body arching involuntary, hips moving, pressing his cunt to his father's cock, his breast bouncing slightly.
Masaru kept on hitting that spot as if teasing, Katsuki is sure he's seeing stars.
"Ah! Hnngh– ah! Fuck! Fuck! Fu– ah! –ck!!"
Shit, if his father continues this, Katsuki would cum, and he would be too mind fucked to stop his own father from cumming inside him, filling Katsuki to the brim. Fuck, knowing how close his father is to his womb excites him.
His father can– would make him pregnant.
Fuck, Masaru can make him a mother, and fill him with his own sibling.
And fuck, how much he wants his father to knock him up.
Shit, Katsuki's mind is fucked. He doesn’t care anymore. His father can fuck him all day, every day, fill him, breed, and knock him, for all he cares, as long his cock is inside Katsuki's cunt, Katsuki doesn’t care.
Masaru switched a flip inside Katsuki.
He woke up a side in Katsuki, Katsuki didn’t even know existed. The way his cock moves inside the younger wakes up a primal version of him, hungry for cock and craving for sex, begging to be filled and knocked up.
He moans, moving his hips sensually, meeting Masaru’s shallow thrusts. “Oh? Is my Love moving by herself, fucking herself on my cock, hm?”
The use of improper pronouns only made Katsuki shiver. Fuck, he’s a she now, is he? He’s a woman, he can be pregnant, and he’s cumming with his cunt.
He is his father’s woman.
“Yes! Ah! Yes, Love! Hnngh–” Katsuki announces, fucking himself to his father’s cock, his movements hasten, and Masaru fell with his pace, moving faster. “Fuck– ah! –me! Ah! Faster! Pl– ah! Ah! Please! AH! Harder!”
Katsuki hears Masaru chuckles darkly, then he slows his pace, pulling out with just the tip inside, and when Katsuki starts thrashing, he rams in, pushing inside at once, making Katsuki see stars.
Masaru did that three more times until Katsuki is a mess of begging and tears and saliva. “Dad– ahhh!-- please.” he moans, not minding his words.
Masaru’s eyes widened, thrusting further, knocking on Katsuki’s womb, eager to let himself in. Katsuki shouts inaudibly, too sensitive and mind fuck to understand what is happening. He's unconsciously meeting Masaru’s thrusts, moaning with each shove and pull, enticing his father more.
“Yes, Love. I will be a Daddy, and you’ll be a Mommy soon,” he says, voice singing. “I’ll fuck you so much we’re sure you’ll have a baby inside you tomorrow,” he added, pacing harder and faster.
Katsuki can only moan, not understanding what is happening in his own unfamiliar body.
His father smirks, feeling Katsuki’s womb meet his cock, eager to be filled. It opens up, letting Masaru shove the tip of his cock inside Katsuki’s womb. It almost feels primal: the need to breed his sweet little Love, the feeling of his Love’s womb opening up for him.
He growls, rough, leaning down, capturing Katsuki in a kiss. Katsuki sobs into the kiss, chasing his father's lips. The tip of Masaru's cock inside Katsuki’s womb prevents the older from making deep thrusts, but that is okay. With this, it is a sure deposit of his seed inside his Love. With this, he'll be sure his Love will be knocked up.
"AHH! Fuuuuuuuck," Katsuki was first to cum, shouting moans as they echo inside the room, joined by the sound of their fucking, and Masaru’s occasional growls.
Three more thrusts in and Masaru cums, pressing his cock directly to Katsuki’s womb, warmth filling Katsuki from his cunt to his insides until it fills his womb, as his father deposits his fertile spend inside him. The tip of his cock plugs the entrance of Katsuki’s womb and prevents any of his seeds from spilling.
Katsuki can almost feel it, how something magical happens inside his body.
A start of life.
Katsuki sinks to the bed once more, panting heavily. His father is still on top of him and his cock inside him. He can feel it twitching like he’s still got more cum to spend.
They remained like that, fitting snugly into each other. Then, Katsuki moved slightly, the cock pulling out of his cunt a mere inch making them both groan.
He moans, as he stutters, “D-Dad…”
Masaru growls once more, leaning away, caging Katsuki's head to the bed with his arms on both sides. “Keep calling me that,” he whispers, then begins fucking Katsuki once more.
Katsuki wakes up sore.
His whole body is aching, but more importantly, he can feel the weight of his father’s arms on his midsection as the older sleeps peacefully behind him.
He curses under his breath, remembering the events that occurred after his father first came inside him: Masaru is a beast in bed, and Katsuki never thought that his father had this kind of side in him.
He fucked Katsuki for hours , dirtying their sheet all over. The sun was already up in the clouds, shining when Masaru stops fucking him and snuggles to his back.
He fucked Katsuki mercilessly, pounding hard and fast. Never slowing down, even if Katsuki begs with a tear-stained face. The squelching sound his cunt made, made Katsuki embarrassed, but he was too fucked to ask his father to stop.
Katsuki thought that alcohol would make someone hard of cumming, but his father came a total of seven times inside him, only pulling out when they changed positions.
And shit, he's sure his father's cum is potent. It's heavy and thick and he's pretty sure his father is backed up, never had sex in months– years– with his late mom.
His father's cum is perfect for knocking him.
Katsuki never felt so full. And the dent he can feel from under his father's hand was enough proof. His father fucked him so much, he looked like he was months into pregnancy already.
Katsuki, being kissed, touched, and fucked for the first time, never thought there are so many ways to get fuck.
His father fucked him when Katsuki was on his hands and knees. He fucked him by the edge of the bed, one of Katsuki’s legs raised in the air. He even fucked Katsuki while Masaru was on the bed, letting Katsuki move on his own.
And Katsuki’s favorite was when his father manhandled him. He never knew his father was strong, but when Masaru carried him from the back, his father’s hands on his knees, bending him and spreading him at once, with his cock, going in and out of his cunt–
Fuck, Katsuki could cum with just the image of it.
No matter how wrong, dirty, and disgusting, Katsuki loved every second of their lovemaking.
And of course, his body agrees, clenching hard on the cock sitting inside his cunt since last night, still half hard and plugging his father’s seed locked inside him.
