Soulmates were a curse for this world. 

Sieun has thought this ever since he was a child. Maybe because he grew up watching his parents and realizing that just because fate decided two people should be together, doesn’t mean that was true. 

Fights. Arguments. Glass breaking. Long away trips with sports teams. More shifts picked up at the office. “Accidental” burns that just so happened to cover their soulmate marks. A divorce that took three years longer than it should’ve because they were soulmates and soulmates can’t possibly be incompatible with each other. 

Soulmates were a romantic ideal of what love could and should be. Soulmates were an ideal. A pipe dream. A stubborn echo of the ancient world that refuses to fade. Soulmates, the very thing that are supposed to be the physical embodiment of love, are the very reason why Sieun grew up without love. 

Ironic, isn’t it?

So, when Sieun’s mark manifested at the same time as everyone else’s, he decided then and there soulmates were not for him. This was not an uncommon decision for most of the younger generations. Too many people had seen the disasters of forcing two people together because fate decided they matched. Too many people like him learned the harsh truth that soulmates were a fantasy tale. 

For many young teens, the mark is a sign of hope. Love. Many of them not yet jaded on the concept. It’s an easy trap to fall into. After all, who doesn’t want to believe that someone out there is literally made to love them? It’s a romantic concept. 

But that’s all it is, a concept. 

For Sieun. the small sunflower outline hidden away on his stomach, was merely another spot on his body. Another mole. Freckle. Nothing significant. It meant literally nothing. No one would see it unless he wanted them to. 

He never looked for his match. Never caught his eyes lingering on any visible mark in a fleeting hope that a passing classmate is his soulmate like his other peers. Not even when they first manifested. He just, didn’t care. 

Even now, in his adult life, he doesn’t care. Love has never been something in the forefront of his mind. He has plenty of platonic love and he is a loving person with his friends. But romantic love? He’d rather avoid that. 

Or, well. Not really avoid it. But he’s not actively looking for it. If he meets someone, he meets someone. And it’s not even about his trauma, for the most part. Dating just seems… exhausting. He had to watch Baku and Gotak dance around each other for literal year until Gotak couldn’t take it anymore. 

He has to be the shoulder Juntae cried on for many a failed dates or worse, being stood up. Dating apps? Arranging dates? Putting yourself on display like a shiny new toy? Exhausting. 

And then there was his actual, real predicament. The one that, if he’s being honest with himself, is holding him back from actually dating. 

Ahn Suho. 

His best friend of 5 years. The person absolutely closest to his room. The man he genuinely almost ruined his life over. Almost killed for. Would die for. 

And Sieun would do it again. And again. And again. He’d do anything for Suho as long as Suho is alive and healthy. Breathing. Not hidden away in a fancy hospital as a well kept secret. Sieun would do anything for his friend. 

His soulmate. 

Suho doesn’t know. No one besides Sieun knows. And Sieun will keep it that way until the day he dies. 

Because that opens a door to a world Sieun refuses to acknowledge. A door that means that his feelings for Suho run deeper than platonic. That his actions in high school and then on, have been made out of some cosmic, love thing. And not because Suho is Suho. And Sieun would turn the world on his axis if it kept Suho alive. 

Sieun does not believe in soulmates. 

But he believes in Suho. 

And he believes in them. In what they have. Sieun is not dumb. He is very much aware that what he and Suho have runs deeper than platonic. He wouldn’t call it romantic by any means. But it’s not the same as what he has with his friends. 

And he would also be stupid if he didn’t admit that whatever he has with Suho, is a big reason on why he has no interest in anyone else. 

Because the thought of anyone coming into his life that could come between what they have? It makes him sick in the stomach. 

Suho wears his sunflower mark on his shoulder. Sieun has always though it was an appropriate spot for a soulmate mark, since Suho wears his heart on his sleeve. And Sieun knew, the second Suho first crashed into his desk and knocked his pen case over, that Suho was his soulmate. 

Which means for 5 years, Sieun has hid this from him. 

People may ask why. Sieun has often wondered this himself. Why would he keep this from his soulmate? Is he that fucked up from his childhood that he can’t even bear the thought of revealing the fact that they’re soulmates?

Well. Yea. Probably. 

But also, (as Sieun likes to argue with himself) Suho has always romanticized soulmates. Unlike Sieun, Suho grew up with lots of love. Surrounded by it from his halemoni and her husband. Who were soulmates. And they worked. So well. 

Suho grew up listening to stories about soulmates. And unlike Sieun, he had real life proof that soulmates work. That it’s just as romantic as it sounds. He’s been dead set on finding his soulmate for as long as Sieun has known him. Always a romantic at heart. 

Sieun knows Suho won’t date anyone who isn’t his soulmate. But that doesn’t mean Suho hasn’t… done things in search of said soulmate. 

He has more experience than Sieun ever will, that’s for sure. 

And does knowing Suho has touched people who aren’t Sieun make his skin crawl? Sure. Does he refuse to listen to Suho recount any encounters from failed dates or hookups? Yes. Does that mean Sieun is in love with his best friend? No. 

It’s just a side effect of being soulmates.

He assumes. 

Because of those ideals. The romanticism that runs through Suho’s veins, the polar opposite of Sieun, Sieun hasn’t told him. 

Because how can he break to his soulmate, who believes in soulmates more than anything. Who wants to find his and fall in love with them, that his own soulmate doesn’t believe in it. That he’s seen it fail and will never curse himself to the same fate.

Sure, it’s selfish to let Suho search high and low for his soulmate while Sieun knows just how close he is, and not tell Suho. But this is better. This is what’s good for both of them.  

Suho finding out they’re soulmates means Suho will want to try and date. That means that everything Sieun has based his life on for the last 6 years is done. Changed. Morphed. And when it inevitably falls apart, Suho will be gone. 

And Sieun can’t have that. 

A life of watching Suho from afar. Being his closest friend. Hopefully watching him fall in love and give up on this silly ideal. Eventually covering up the mark with a tattoo so Suho will never know. That is better than rising it all and losing him.

And Sieun is very, very careful not to let Suho in on the knowledge he’s hiding. 

His mark is in a very convenient spot to hide regardless. But Sieun has mark concealer that he puts on just in case. Every day. Even if he knows he’s not seeing Suho that day. Sure, Suho has never seen Sieun with his shirt off. Or Sieun in a crop top. But if Sieun’s shirt happened to ride up, he would lose it all. 

And Suho has pried Sieun on his mark. Begging to know where it is. What it is. Why doesn’t Sieun look for his soulmate.  If Sieun knows his soulmate already  

Sieun has become very good at dodging questions and telling half truths. 

“It’s a type of flower.”

“It’s somewhere you can’t see it.”

“It’s not on the top of my mind right now.”

And despite all of that. All of that careful planning and scheming. And Sieun still dropped the ball. 

“Sieun-ah. What is that?”

Of all things, of all fucking things, that get him caught, it’s him getting out of the shower. 

He never should’ve given Suho the code to his apartment. 

Sieun is currently only in boxers. He was in the process of drying off his hair and then he would put the concealer on. Like he does every time he showers. 

He was not prepared for Ahn Suho to burst into his bathroom at 10 am with zero warning. 

He was not prepared for Suho’s eyes fly immediately to his navel. 

He was not prepared. 

“What’s what?” He decides to lie. 

“Don’t do that shit.” Suho slams the door shut and Sieun jumps. Covering the mark with his hands is too obvious. Willful ignorance will probably be his best move until he can figure something smarter out. 

“Your mark.” Suho steps closer. Sieun shuffles back. Suho’s not even looking at his eyes. His eyes are firmly on Sieun’s navel. Suho’s hand comes up to brush along the twin mark he has on his shoulder. “It’s mine.”

“It’s not the same-“

“It is,” Suho snaps. He steps closer. Sieun’s feet are against his bathtub. He has no where else to retreat to. Suho reaches his hands out, like he’s going to grab Sieun’s waist. 

Panic flares in Sieun’s chest. 

“Sieun. We’re so-“

“No. We’re not.” 

Sieun cuts his friend off and twists away. Twists around the taller man and towards the door of the bathroom. 

“Sieun-“

“We’re not.” Sieun slams the bathroom door shut and books it for his room. 

He does the only thing he can. 

Calls Juntae. 

“Pick me up from my place now. Do not say a word to Suho.”

—

“YOU’RE SOULMATES?”

“Yes.”

“And you knew this whole damn time?”

“Yes.”

“And you hid it from Ahn Suho. You’re best friend. You’re soulmate.”

“Yes.”

Juntae stares at him. And stares hard. Mouth slack and half open in mild shock. “I can’t fucking believe this. Sieun, this was stupid.”

“I didn’t ask you for advice. I asked you to come save me,” Sieun can’t help but spit out over his cup of coffee. 

Juntae snorts. “And it sounds like you need to be saved from yourself. How on earth did you think hiding this from Suho was a good idea?”

“Juntae you know how I feel about soulmates.”

“Yea and?”

“And you know how Suho feels about soulmates.”

Juntae tilts his head, pushing his glasses back up on his nose. “I’m not sure I’m following.”

“We can never work. Soulmates don’t work.”

Something in Juntae’s face softens marginally. “Sieun-ah.”

“No, Juntae. Don’t even try.”

“Sieun-ah. Listen to me.”

“No.”

“Just because it didn’t work for our parents, doesn’t mean everyone is cursed to live like that.”

“And what if that’s what happens to us?” Sieun fires back. Venom in his voice. Not really at Juntae. But at the damn makes that cursed him to be in this spot in the first place. Whatever greater being decided this was how humans found love. Whoever forced him to be in this position.

“What if we end up exactly like them? Dating. Getting married. Slowly hating each other. Resenting each other. Going through years of divorce and then I never see him again? I can’t- I won’t do that Juntae.”

Juntae smiles sadly. Those soft eyes lowering Sieun’s walls just a bit. “I understand that Sieun. I know how much he means to you. And I know how much it would hurt you to lose him again.” A warm hand caresses Sieun’s knee. 

“But this isn’t a decision only you can make anymore.”

Sieun blinks. “But-“

“It’s not,” Juntae cuts in. “Don’t be selfish and take this choice away from Suho. You know better than anyone how he feels about soulmates. Do not hurt him like that. You owe him at least a conversation.”

Suho seems hellbent on more than a singular conversation if the way Sieun’s phone has been blowing up, is any indication.

“Juntae.” Sieun swallows. Swallows back the sting behind his eyes and the burning of his throat. “I can’t lose him.”

“No one said you are,” Juntae answers. 

—

Suho is gone by the time Sieun is dropped off at his apartment. Sieun has also been ignoring every message Suho has been sending him. Every phone call. Ignored. Every one of them. 

By the time he and Juntae part ways and settle on a course of action, Sieun truthfully just doesn’t have it in him to have this conversation at the moment. So, he just ignores. Suho will come to him one way or another. 

And come he does. 

At 7 am that next morning. 

Sieun is already awake. He hasn’t sleep at all since he got back to his own place. 

He’s sipping coffee when the door is thrown open and an angry Suho comes storming in. Sieun doesn’t even flinch. Or even really look at Suho. Not yet. 

“Yeon Sieun,” Suho says. 

Sieun swallows around the bitter taste in his mouth, not just from the coffee, and stands up. He turns and faces his friend. “We need to talk.”

Suho blinks. Obviously taken aback by Sieun’s direct choice of words. Clearly expecting at least some sort of argument. He lets the door shut behind him and clears his throat. 

“Yea, we do.”

Sieun jerks his head to his room. “Come on.”

He leaves his coffee behind and pads towards his room, not checking to see if Suho is following. He knows he is. 

Sieun has had this very conversation in his head many times. Imagined every possible way it could play out. Tried to think of every scenario, just in case. 

And as he sits on his bed and pats the spot next to him, he finds he’s not sure where to start. Or even what to say. Should he apologize? Rip the bandaid off?

“How long have you known?”

Or, Suho will start. 

Sieun blinks, fixing his gaze on the floor instead of on his friend. “Since we first met.”

“Like, since we became friends?”

“No, since you first crashed into my desk in high school.”

Suho sucks in a breath. Sieun still isn’t looking at him. “Sieun-ah, that was 5 years ago.”

“I know.”

“And-“ Suho’s voice wavers a bit. “And you hid it from me all this time? Let me wander around. Date around. Sleep around, hoping I’d find you? Instead of telling me?”

“You weren’t looking for me. You were looking for a soulmate,” Sieun mumbles. 

“It’s the same fucking thing! You are my soulmate!”

“It’s just a mark Suho.”

The room goes dead fucking silent. It sounds like the even the air inside the room vanishes. 

“What?”

Sieun lifts his head to look at Suho now. He takes a breath and yanks his shirt up to reveal the bane of his existence. Suho’s eyes fly towards it instantly. “It’s just a mark! It means nothing! It’s pigment on skin. It doesn’t magically mean you’ve met the love of your life.”

“Sieun-ah.” Suho’s gaze whips up instantly. “Don’t. You know how I feel about soulmates.”

Sieun can’t stop the bitter chuckle from leaking out of his mouth. “Why do you think I kept this from you? Because I don’t feel the same Suho. To me, soulmates are a scam. The universe doesn’t know shit. It doesn’t know you. It doesn’t know magically what makes a relationship work or not. It’s a blind fucking guess that doesn’t mean anything!

Suho’s gaze begins to turn watery. But Sieun doesn’t stop. He can’t. Not until Suho knows how bad of a fucking idea this is. Until he sees for himself why they can’t be soulmates. 

“It didn’t work for my parents. It didn’t work for Juntae’s parents. It didn’t work for 47% of the population! It’s a blind fucking guess. You’re better off meeting people and finding love for yourself. Marks mean nothing Suho.”

Suho’s sniffing but he’s not crying. Not yet. 

Sieun jerks his head towards the door. “Don’t you see? Don’t you get it?” He motions between their bodies. “How can we be soulmates when we fundamentally disagree on the foundation of our relationship. And I-“

Sieun forces himself to suck in a breath. “And I can’t lose you Suho. You’re my best friend. My life is nothing without you. I can’t risk you on something mystical and elusive like a mark. So go, go out there and find someone who can love you. And cherish you. And love you the way a soulmate can. Because I can’t.”

A few tears have slid out of Suho’s eyes, but he isn’t really crying. He reaches for Sieun but Sieun jerks back, forcing Suho’s hand falling to the mattress. Their eyes meet. 

“Sieun-ah.” He scoots closer. Sieun retreats back. “Stop that.” His hand shoots out and grabs Sieun’s knee, squeezing firmly. It works, because Sieun stiffens instantly. 

“I’m not going to try and change your mind, because you won’t change mine.” A soft squeeze to his knee. “But don’t you see that what you’re doing is out of love?”

Sieun swears he feels the breath leave his lungs at the word love. 

“Even if you yourself don’t recognize it. Or even really understand what you’re doing.” Suho shuffles closer and Sieun can’t pull away this time. “Hiding this from me because you knew you didn’t feel the same way as I did. Hiding this because you didn’t want to lose our friendship…” Suho smiles softly. 

“Sieun-ah. That’s love.”

Sieun’s shaking his head slowly. Even if he knows Suho is making a bit of a sense. 

Suho merely nods in response. “Protecting me in the only way you knew how? Trying to let me find someone out there on my own? Yea, at first I was mad that you hid it for so long because it’s my life too, but I understand Sieun-ah.”

Another squeeze. 

“But you don’t get to decide this for us. You don’t get to decide if we give this shot or not. At least, not on your own.” 

Suho’s hand slides under Sieun’s shirt. His fingers dancing along warm skin. Only for his palm to press gently against Sieun’s navel. On the mark they now both know is there. 

Sieun ignores the shiver that surges through him. Or the sudden warmth bubbling in his belly. He forces that all down and stares into Suho’s gaze instead. Using that to ground him and ignore everything. 

“Do you have any idea how often I laid awake at night begging for the universe to make a mark appear on you? Wondering why it couldn’t be you? Thinking about how easy it would be with you?” Suho presses a little harder on Sieun’s belly. Makes Sieun’s breath catch. 

“Sieun-ah.” Suho is leaning in. 

“You won’t lose me. You know that right? You could never lose me.”

And maybe Sieun is leaning in now too. He can’t tell. All he knows is that the space between their faces is slowly vanishing. And that Suho’s hand is very warm. And that his belly is starting to burn. 

“Suho, you’re my world. I can’t lose you,” Sieun murmurs. 

“Sieun-ah, you’re my universe.” A gentle finger scratches along the mark. “You won’t lose me.”

Sieun’s under Suho’s hand. Both of their gazes are flipping between each others lips and the others eyes. Sieun swallows softly. The back of his eyes stinging a bit. Deep down, maybe he knew Suho wouldn’t just walk away. That he would fight for this. But, maybe Sieun just needed to hear it. 

The tears overflow. 

And like a dam broke deep inside him, they don’t stop. 

Sieun starts to cry harder. Tears steaming down his face. Heaving breaths. Hiccuping. It’s scary. The thought of losing Suho is physically painful. And his worst nightmare. He can’t lose him. 

“Sieun-ah,” Suho’s voice breaks and his hands fly up to cup Sieun’s face. Warm thumbs swipe across his cheeks. “Sieunnie. Baby. Don’t cry.”

The words do nothing but make Sieun cry harder. Lean into the touch. Hiccuping out Suho’s name and cling to his wrists. Like he’ll vanish is Sieun stops touching him. 

“Baby. Baby please. Please it’s ok. I’m here.”

And then soft lips are covering Sieun’s own lips. Swallowing down his soft cries. Soothing everything deep inside Sieun that he didn’t even know was aching. 

And as Sieun kisses him back. As Sieun tries to convey everything he doesn’t know how to say into the kiss. As his cries fade, his belly burns. 

Hot and bright. 

Something warm and sharp bursting in the same spot as his mark. 

Sieun breaks the kiss with a hiss and rips his shirt up again to investigate the sudden sensation. 

“Sieun-ah? Did it-“

“It changed,” Sieun gasped. 

His soulmate mark. It grew. Spread out along his soft belly. Where once it had been a simple sunflower near his belly button, it now was much larger. Large leaves sprawling out along either side of his belly button. Swirling stems under the soft skin of his belly. The flower itself seemed bigger. The entire piece now maybe the size of Suho’s palm. 

“What the hell happened?” Sieun whispered. 

“I don’t know. I didn’t know they could change.” Suho reaches out and presses his palm along the new mark. 

Lightning shoots through Sieun’s body and a sharp whimper is spilling out of his mouth before he can stop it. 

Both of them freeze. Eyes wide. Meeting. 

Even as a heat begins to simmer away in Sieun’s belly. Right where his mark sits. Where Suho’s hand is resting. 

“Sieun-ah, what was that?”

“I don’t- oh-“

Suho presses down on his belly again and another incriminating sound spills out of Sieun’s mouth. This time though, Sieun can’t find it in himself to be ashamed. Not as the heat in his skin blooms like his mark. Not as that heat makes him press his legs together and his cunt throb. 

“Fuck. Sieun-ah. Am I hurting you? Should I stop?” Concern laces Suho’s voice but his eyes are dark with lust. 

“No!” Sieun gasps. His hand flies out to grab Suho’s wrist. Pressing it harder against his soft belly, the tension just right and making another wave of pleasure pulse through his body. 

“Oh fuck,” Suho whispers. 

A heat takes over Sieun’s brain from there. All he can think about is how good Suho’s hand feels on his belly. How right the tension feels. How he wishes his belly was even tighter. More full and round. Swollen with-

Sieun gasps. 

“W-what? What is it baby?” Suho stammers. 

And like a fever has taken over Sieun’s mind, he grabs Suho’s shoulders and shoves him onto the bed. His friend, his soulmate gasps. 

Sieun straddles him. Settling himself right on top of Suho’s hardening cock. He can feel it slowly hardening as it settles on it. He can’t help but bite his lip and roll his hips down just a bit  Just to tease. 

Suho lets out a sharp sound, his hands flying up to grab at Sieun’s thighs. “S-Sieunnie. What’re you doing?”

His belly, his womb burns. Burns with the need to be stuffed. With the need for his belly to be swollen and filled with a baby. With Suho’s baby. 

“I need you to knock me up,” Sieun answers. Like it’s the most normal and sane thing he’s said all night. 

Suho’s eyes stretch wide. His mouth drops open, even as his hand squeeze the thighs bracketing him. “Sieun-ah. You’re not thinking clearly. Hm? Let’s slow down just a bit- shit.”

Sieun does not like that answer. 

He grinds down hard on Suho, savoring the way he can feel it twitch under the joggers he’s wearing. Savors the sharp hiss that punches out of his friend. 

“I’m thinking clearly,” Sieun argues. 

Suho swallows, a bead of sweat shining at his hairline. His fingers digging deep into Sieun’s thighs. “Sieunnie, I don’t know-“

Sieun hisses and grabs the bottom of his shirt. He yanks it off and over his head in a single motion. Baring himself and the new mark settling over his womb. He grabs Suho’s hand off his thigh and brings it up to his navel. 

Their eyes meet and Sieun presses down on his mark. 

Both of them let out a shaky sound and Sieun presses down harder. His brow furrows, heat trembling between his legs. A shaky sigh slips from his mouth. 

“Don’t you want to knock me up Suho-yah? Don’t you want my belly swollen and round and carrying your baby?”

He can see Suho’s pupils dilate in real time. Feels the way he presses just a little harder on Sieun’s soft belly. Can practically see Suho imagining it. 

“Imagine this little mark all stretched out over my belly Suho-yah. A sign for everyone to know what you’ve done to me,” Sieun whispers as he guides Suho’s hand to rub. 

Suho’s mouth is parted still, even as he begins to rub small circles on Sieun’s belly. Where his womb would be. Where his mark now sits. Sieun licks his lips. 

“Come on Suho-yah.” A soft grind down on his very hard cock. “Put a baby in me.”

Suho groans and Sieun can see the second it unravels. The second his self control gives way to Sieun. 

Suho likes breeding. Noted. 

Apparently so does Sieun. 

Sieun moves his hands to Suho’s waistband and begins to tug them down, when Suho’s hands encircle his wrists and stop him there. Sieun’s gaze whips back up. 

“Sieun-ah.” Suho swallows. “You’re sure this is you? That you want this? With me?”

Sieun feels his mouth pitch into a pout. “Who else would I want?”

Suho’s eyes flare and a shaky groan falls out of his mouth. “Fuck Sieun-ah. You can’t just say shit like that.”

Sieun grins but before he can continue on his mission, Suho has their positions flipped. Sieun pressing his back into his sheets, his friend looming over him. 

“Sieun-ah. Would you call me a perv if I said I’ve thought about doing this to you more times than I can count?”

Sieun licks his lips, wiggling his hips as the throbbing in his cunt begins to worsen. The mark on his belly begins to sting again. Sieun whimpers.  

“You are a pervert Suho-yah,” Sieun mumbles. 

Suho chuckles and then warm lips are covering his again. 

Sieun sighs sweetly into the kiss, opening his mouth as Suho begins to lick inside and deepen it. The kiss quickly turns filthy. With Sieun bucking his hips up and Suho grinding his hips down. 

Both of them moan into the others mouth at the contact. The throbbing in Sieun’s cunt starting to kick up. He whines again, hands scrambling to grab at Suho’s waistband. 

“Off. Off. Off. Get inside me.”

Suho moans and swallows Sieun’s words with another kiss that makes Sieun’s toes curl. It’s very hot and all but the burning on Sieun’s belly is starting to turn unbearable. 

“Suho-yah,” Sieun breaks the kiss with a whine. His cunt throbbing. His belly burning harshly. “Stop teasing and breed me.”

Suho blinks. “Don’t you want-“

“No. Breed me. I want you to stuff me full of your cum and knock me up,” Sieun demands. 

“Oh. Ok.”

Clothes are shed faster than Sieun can keep track after that. All he’s really aware of is the throbbing in between his legs and the burning on his belly. The insistent need to be bent over and fucked silly on Suho’s cock until it has no choice but to take. 

Some tiny, still rational part of his brain whispers that it’s physically impossible for Sieun to get pregnant but that thought is quickly shut down the second Suho’s cock is revealed to him. 

He’s decently big. Rock hard. Precum beading at the tip. 

“Suho-yah,” Sieun inhales. His cunt clenching at the mere sight. “You’re perfect for me.”

Suho’s cock twitches and Sieun can’t help but giggle. “Do you like when I praise you Suho-yah?”

Suho flushes and bends down, covering Sieun’s body with his own. Their lips graze and their eyes meet. “I like anything you do to me baby. I like you.”

This makes Sieun flush and his belly sting. 

“Prove it,” he breathes. “Get me pregnant.”

Suho groans and grabs the base of his cock finally. “Sieun-ah.”

“Hyung if you don’t fuck me silly right fucking- oh.”

Suho’s cock drags along Sieun’s soft folds for a few seconds before he presses just the tip inside Sieun. The reaction from Sieun is instant.The burning on his belly flares brightly before simmering down and he lets out a pleased noise as Suho stretches him open on his cock. 

“Oh fu-“ Suho chokes out above him. 

One of Sieun’s hands fly up to grab at Suho’s shoulder. The other presses down on his belly. “More,” he pleads. 

Suho groans and nods, burying his face in Sieun’s neck as he presses inch after inch inside Sieun. Sieun gasps and arches, spreading his legs as wide as he can. Groaning as his cunt stretches to fit all of Suho. It burns just a bit but it’s nothing compared to the bone deep satisfaction he feels at finally getting what his body has been craving this whole time  

His cunt pulses and sucks Suho in further and further. Both of them panting and moaning as Suho nestles himself inside Sieun. And when their hips meet flush, Suho fully buried inside Sieun, their lips meet again. 

It’s sloppy and messy  Drool leaking out of their mouths. Soft groans spilling out of Suho as Sieun pulses around him. The burning on Sieun’s belly has subsided a bit but it’s still there. 

“Suho-yah. Move,” he breathes. 

Suho breaks the kiss, a dazed look in his eyes as he processes Sieun’s words. “Yea. Yea ok.”

He pulls out a bit before gently rocking his hips back into Sieun. Sieun arches, moaning sweetly as he presses down on his belly. Suho groans above him as he sets a gentle pace. It’s very sweet and romantic and Sieun knows he should appreciate the care Suho is giving him. 

But now, he just wants to be fucked silly. 

“Hyung harder,” Sieun pleads. 

He feels Suho’s hips falter for a second and hears him swear under his breath. “Fuck Sieun-ah. Are you sure?”

Sieun claws at Suho with his one hand, and he feels tears of frustration prick at his eyes. He needs it. He needs to be bred and fucked silly. He sniffles and nods. 

“Fuck me until I can’t speak Suho-yah. Until all I can say is your name and whine and moan. Until I’m drooling and boneless. Until it takes and I’m waddling around with your baby.” 

Suho stills. Their eyes meet. Sieun sniffles. His cunt throbs and the burning of his belly won’t leave. 

“Fuck ok baby. Ok.”

Suho quickly pulls out and Sieun immediately whines at the loss. He doesn’t get much time to mourn the loss though, before he’s being manhandled onto all fours. 

He gasps as Suho presses down on his lower back and forces his body into a deep arch. One hand grabs his hip, the other pressing down hard on Sieun’s womb. 

“To make sure it takes baby.”

And then Suho is slamming inside. No gentleness. None of the softness or care of before. He snaps his hips forward and buries himself completely deep inside Sieun in a single thrust. 

Sieun cries out instantly, clawing deep into the sheets. Even as his cunt takes it all eagerly. Even as the burning on his belly eases a bit. 

“Fuck! Fuck just like that hyungie.”

“God you have such a filthy mouth Sieunnie. Who knew hm?”

Suho pulls out and drives his hips forward again. The sharp sound of their skin meeting drowning out the whimpers of Sieun’s pleasure. And Suho does it again. And again. Setting a brutal pace that has the bed squeaking and Sieun blabbering out nonsense. 

His cunt squelches as slick trickles out of him. As Suho fucks him dumb. Their bodies slapping loudly in the empty room. Both of them moaning and whimpering loudly. 

Suho pressing deep into Sieun’s mark, his hand never wavering from that spot. As if he can feel Sieun’s cunt taking it all. 

“Feel sooo fucking good baby. So much ah better than I thought you would be,” Suho groans. The words make Sieun’s cunt flutter and his toes curl. 

“Suh-Suho-yah,” Sieun slurs as he arches deeper. 

“Fucking love the way you say my name baby.” Another deep thrust and a sharp whimper punches out of Sieun. 

“Fuck!” he gasps. 

“Your cunt just sucks me in baby.” The hand pressing down on Sieun’s womb drifts to between his legs. A single running through Sieun’s folds. Collecting the slick from where they’re connected and dragging up to his clit. 

“Made for me weren’t you?” 

A warm tongue drags up Sieun’s spine. The dual sensations making him buck and gasp, clenching tighter around Suho and throwing his head back. “Oh fuck.”

“Yea? You like that baby? You like the way hyung fucks you?” Another harsh thrush that sends Sieun up the bed. Paired with two fingers rubbing harsh circles on his clit. The pleasure is suddenly overwhelming. Suho is everywhere. Inescapable. 

“Like the way hyung knocks you up hm? Fucks this perfect pussy and stuffs you so full? Shit. Until your pretty, soft belly is stretched and round with my baby? You want everyone to see what I can do you hm?” 

Thrust after thrust that has Sien sputtering and drooling onto the sheets. The way Suho talks and strokes his clit, like he’s memorized every aspect of Sieun’s body already and knows what he needs. 

Sieun drags a hand to his stomach and presses down on his mark again. 

The pressure on his belly makes him moan again, eyes rolling back as Suho strokes his clit harder and faster. He can picture it so easy. Suho’s cum staying deep inside him. Painting his insides white. Sieun clenching to keep it all inside. 

Then several months down the line, the way Sieun’s belly stretches to accommodate a new life. The skin pulling taunt and his belly growing bigger and bigger. Suho rubbing his belly and kissing it and-

“Fuck!” Sieun cries out. He presses  on his belly harder as Suho aims a particularly deep thrust inside him. Sieun’s entire body is trembling. His cunt clenching and throbbing with every drag on his sensitive walls. 

“S-Suho-yah I-“ He’s slurring. 

“Wanna cum baby? Hm? Wanna cum all over hyung’s cock?” Another drag of his tongue along Sieun’s spine that has Sieun keening. “Want hyung to cum inside you now? Knock you up the way you need?”

Another swirl of his fingers on Sieun’s clit. Another deep thrust. More broken moans spilling out of Sieun’s throat as he nods over and over. Starts to fuck himself back onto Suho. All while keeping a firm pressure on his belly.

“C’mon Sieunnie. Let’s cum together hm? Cum on hyung’s cock,” Suho pants into Sieun’s ear. 

His legs are trembling and he’s not even sure he can form full sentences anymore. But the knot in his stomach is tight. His cunt js throbbing. The mark burning. And Suho is filling him so well. Playing with his clit in ways that make him see stars. And his mouth is fucking filthy. 

“Hy- ah fuck- hyungie-“

“Cum. Cum Sieun.”

Sieun’s body suddenly pulls tight as that knot in his belly reaches its tipping point. His legs shake and he lets out a sharp cry of Suho’s name. 

He cums in harsh waves, spasming and pulsing around Suho’s cock. Burying his face in the pillows as he whines and Suho fucks him through it. 

Suho thrusts once. Twice. And then buries his face in between Sieun’s shoulder blades as he cums. Pumping Sieun full of his cum in thick spurts that has Sieun sighing in satisfaction. 

Both of their hands entwine and press down on Sieun’s womb as Suho rides out their hides. Both of them moaning softly as bone deep satisfaction sweeps through Sieun. 

Both of them collapse after that, Suho maneuvering them so Sieun nestles into his neck. The burning on his belly has faded. 

“Yah- Sieun. Look.”

Sieun grumbles and shakes his head, comfy from where he’s hidden in Suho’s shoulder. 

Suho huffs a laugh and then gently grabs Sieun’s chin, guiding him out of his shoulder. “Look at your mark.”

Sieun frowns but obeys. 

“What the fuck is that?”

It’s glowing. His mark, which was certainly not glowing before. Is now glowing a soft blue. It’s not burning anymore but Sieun assumed it would fade back to normal after this. Not fucking glow. 

“Does it hurt?” Suho asks in wonder as he traces Sieun’s mark again. Sieun shakes his head. 

“No. It feels normal.” 

Suho hums as he traces the mark, before he flicks his gaze back to Sieun. “Think that means I really knocked you up?”

Sieun hits him with a pillow. 

—

The next morning, Sieun’s mark is gone. 

Well, not gone but it’s back to normal. Back to a normal sunflower. 

And he’s waking up in the arms of Suho. 

His soulmate. His best friend. His boyfriend. 

And as Sieun stares at his newest appointed boyfriend while he sleeps, he finds himself smiling softly. Maybe he can have this. Maybe soulmates aren’t a scam of the universe. 

Maybe soulmates aren’t all that bad.
