Sieun is a freak. And Suho knows this.
He’s known for the past several years of them being intimate with each other.
Each year they become even more comfortable with each other... and a little more nasty, too.
And it's good, it's really fucking good, actually.
But… Sieun is a freak.
So, eventually, he doesn't just want to be fucked against the walls of a storage closet in a busy building, he doesn't just want Suho to eat him out until he’s crying and there's a real life slip and slide between his asscheeks.
He doesn't just want to have car sex under that abandoned bridge in the city, he doesn't just want spankings and sometimes without even being fucked, so he can just cum from that.
Suho already struggles a bit with smacking Sieun's ass while he goes nose diving into their mattress, mathematical curve to his back, showing himself off for Suho. He only can do it because he figures he's not treating what's sitting in between his cheeks much nicer.
And it's Sieun's plump little ass, there's a lot of meat there. There's a nice cushion.
But, Sieun doesn't just want those open palm smacks on his ass while Suho is fucking up into him and bending him over various things.
He doesn't just want hickies on his neck so he can show them off and let everyone know he belongs to someone. Someone so dizzyingly perfect for him.
Sieun is so beyond comfortable with him now, so he wonders about more than being roughly manhandled and tossed like a fucking garden salad - extra dressing - by Suho.
“What?”
Suho is deep inside of this man and almost stilling completely, in shock, but Sieun’s heel digs into the dip in his lower back, so he keeps up the pace.
Sieun moans out again, “Choke me, Suho-yah, please.”
“Choke- choke you?”
Suho starts slowing down again.
“Suho, fuck me!”
Speeds up.
“I am!”
Sieun wrangles one of Suho’s hands off of the mattress which causes him to crash down chest to chest with Sieun again, which is very nice. He's so warm.
“Hyung, choke me.”
Sieun literally grips Suho’s hand and wraps it around the front of his throat, like, actually feels out his fingers and spreads them across his throat how he wants them, puts his thumb on the opposite side. Then he holds Suho’s wrist loosely with one hand, the other coming back into his hair.
Suho looks at his own hand there and it just. Doesn't look right.
“Sieun-ah…”
“Choke me, hyung, please,” Sieun begs of him, with that pleasured frown etching his pink face. “Please.”
Suho hums in slight distaste, but when he just ever slightly squeezes his hand around Sieun’s throat, he moans a little louder. And when Suho does it again, hating the way the bones in Sieun’s pretty throat feel under his palm, Sieun arches off the bed.
“More more more more, please.”
More. Just a little, and sure to be at the sides, where his real airways are, not his trachea. Suho’s never done this to him before, Sieun’s never asked, but he's heard and read enough to know where to tighten his hold.
“Fuck, Suho,” Sieun manages to pant out, “More more more.”
More.
Again, just a little more.
Because Suho really doesn't like the sight of his own hand wrapped around Sieun’s throat like this, squeezing the air out of his lungs.
It’s enough for Sieun’s eyes to still roll to the back of his head, letting himself get bounced around on Suho’s dick, which is actually not even as hard as it was fifteen seconds ago because he was asked to choke him.
Suho does his tricks and gets Sieun to cum fast, and he immediately releases his hand from his throat and cums right after him.
Sieun’s loving it, still, blissed out and in a world Suho wishes he could be in with him, but his stomach is twisting up with something other than pleasure and they're not mixing well.
After he pulls out and flops next to Sieun, Sieun, like clockwork, attaches himself on top, straddling his hips, both of them panting like crazy.
“You okay?” Sieun asks softly, noting Suho instantly once he’s come down a bit. He brushes a hand through his sweaty hair.
“Yeah, baby,” Suho says, and it’s not a lie. He is okay, he just doesn't really understand what he’s feeling right now.
“You feel good, hm? You liked that?”
“Yeah,” Sieun smiles, leaning forward and nosing at Suho’s throat a little. Nibbles on his Adam’s apple just because he can.
Suho gasps and laughs gently with the feeling, wrangling Sieun’s shoulders around until he’s just resting on his chest.
“Suho, I love you so much,” Sieun whispers to him, right at the lobe of his ear, then he catches it in between soft teeth.
“I love you back,” Suho murmurs to him, his fingers trailing down Sieun’s back, in the divet of his spine, feeling each vertebrae.
“You’re my baby, you know that right, Sieun?”
Sieun nods and hums his affirmation into his neck, leaving open mouthed kisses there, his heart thumping away against Suho’s upper ribs.
“Okay,” Suho replies, quietly.
But he knows Sieun couldn't possibly understand what he’s even trying to say. And he doesn't really either, but that felt important to relay. To resend into the atmosphere.
You are my baby. Which means I don't want to hurt you.
~
It happens again, naturally, because this is Sieun, and once an obstacle has been cleared, he has no problem putting the pedal to the metal.
So, a week later and he’s asking Suho to choke him harder.
More more more more, hyung. And then, I don't wanna breathe, more please, Suho-yah.
Suho tells Sieun No very often, because he’s a brat- only around him. He just never has during sex. Never felt the want or the need to tell him No when they're exploring each other and making each other feel good.
His hand tightens and Sieun’s skin folds and fills in between his fingers a bit, and Sieun’s eyes go rolling like bowling balls into the back of his head again.
And then he’s making a real choked off sound, and Suho snatches his hand back.
Sieun jerks his head back down, from his place on top this time, big frown on his sweaty, fucked out face.
“Why? Stop, put it back,” He says, out of breath, and grabbing Suho’s hand again to return it to its place.
Suho can feel himself frowning too, other hand on Sieun’s waist while he rides him so much better than any cowboy in the world.
“I like it, Suho-yah,” Sieun tells him, eyes all wet and lust-filled, covering Suho’s hand with his own, making his fingers squeeze.
“I promise, do it more, please please, I like it.”
Suho just mumbles, “Okay, baby,” so quietly, and he tightens his grip on Sieun’s throat just that much more.
Sieun arches and throws his head back again, keeping Suho’s hand where it is. He makes Suho choke him more by squeezing his own hand around his, more broken sounds coming from him that sound more like actual choking, like he really can't breathe.
And those are just not sounds Suho’s ears enjoy in the slightest. He almost lets go, but Sieun cums untouched, just like that.
Ropes of white paint Suho’s stomach and his chest, and he helps Sieun through that while he cums right after him, like always.
Suho bites at his lip while he watches himself fuck the both of them through their orgasms from the bottom, slowly releasing the hold on Sieun’s flushed neck, trailing his hand down his chest.
Praying that Sieun doesn't wake up with any bruising there, he truly will not forgive himself. He doesn't care if Sieun would like the finger marks.
Suho’s still frowning, lost in his thoughts, but Sieun can't see because he's collapsing onto his chest and heaving out the pleasure, humming and purring on Suho, licking and sucking at the sweat that’s sheening on his skin.
Suho just runs his hands up and down Sieun’s backside, sometimes circling his fingers against the pockets of his pelvis, on the side of his thighs.
They're both still coming down, especially Sieun, and Suho just can't help the feeling in his stomach.
The image of Sieun with his hand around his throat like that. The choked off and worrying sounds he was making, truly struggling to breathe.
But he likes it.
Suho doesn't like it.
~
Third time's always the charm, right?
“Baby,” Suho sighs, and he literally watches his dick twitch when he feels it, but it's only because Sieun looks so pretty on his knees.
“Just do it, soft,” Sieun says, blinking up at him, and kissing Suho’s tip with his soft lips.
“I don't really want to do that to you, baby,” Suho says, and his right hand is still moving through Sieun’s hair, all around his head. “Just wanna cum in your mouth, Sieun.”
“I think it’d be hot,” Sieun says, then he flicks his tongue and sends it into Suho’s slit, which makes him jerk like crazy, his knees billowing.
“Just do it soft, Suho-yah, you’re not gonna hurt me. I trust you. Trust yourself.”
It's not really about trust, though.
Suho reluctantly moves his free hand from his side, and it's his left, so that's good. Non dominant.
He simply presses the pads of his fingers against Sieun’s cheek.
Because Sieun is asking to be slapped while he gags on his dick.
Two weeks to graduate from choke me to slap me.
“Hyung.”
“Baby, I-,”
“Stop being so scared, I’m not scared.”
Then he swallows him down all the way, no problem.
Suho moans his name and pulls his hand back a bit, and just taps. Enough to make a little pop sound.
Sieun’s eyes flutter closed, and while Suho likes the sight of him so pleasure-filled, he doesn't like what has to happen to gain it.
Sieun comes off of him with a wildly wet noise, his hand moving up and down so slick.
Brown eyes like the high beams of a monster truck when he looks up at Suho.
“Harder.”
“Sieun.”
Sieun frowns, bottom lip flopping out more than his top one.
“Fuck,” Suho groans, and his hips push forward, sending the head of his dick to the center of the pout in Sieun’s puffy lips, and he pulls his left hand back again and taps Sieun’s cheek harder than he did before.
Sieun’s jaw falls slack, letting in Suho’s tip while his eyes flutter closed.
Suho… softly slaps.
The noise Sieun makes keeps him hard, but Suho isn't exactly enjoying himself anymore.
Sieun’s humming on his dick, his hands gripping Suho’s hips. He taps those bones and Suho isn't stupid, so he knows what it means.
And he softly slaps Sieun’s face again.
Sieun gets impossibly more noisy, and the vibrations just ripple through Suho’s cock, so he cums down his throat, hand in his hair, other hand cupping his jaw softly.
Once Sieun swallows it all, some of it spilling from the corners of his mouth, he pulls off of him.
“One more time.”
Suho huffs and just does it.
Sieun's head turns with this one, and it wasn't even harder than the last.
Suho's chest tightens and his breath hitches with the whole motion, as if he really just slapped Sieun's sweet face so hard that his head had to turn with the momentum.
Makes him feel fucking sick.
Sieun bites his lip when he looks back up at Suho, cheek blooming, still with cum and spit oozing like syrup down his chin.
He likes it a lot.
Suho does not like it. He hates it.
~
Third time is not the charm, it’s the fourth.
And Suho will be damned before he lets it get to a fifth.
They don't bottle stuff up from each other, much less for three weeks.
“Suho? What's wrong?"
Suho's been in the bathroom for the past five minutes, after pulling out of Sieun and making sure he was okay from the sex. Rolled off their bed, pulled on his boxers, went to the bathroom to breathe and think.
Thinking about how he slapped Sieun hard enough that Sieun’s cheek isn't flushing from shyness, but from the weight and force of his hand. Choked him hard enough to make him cough.
Suho's hands feel like they aren't his.
“Sieun,” Suho breathes his name, and his head is hanging forwards, the muscles of his cervical spine stretching and rounding over.
His fingers wrap around the edges of the sink a little more. He genuinely feels sick.
“Suho-yah,” Sieun says again, and he steps into their bathroom with him, and comes up on his side, wrapping his arm around his waist from behind.
He puts his chin just behind Suho's shoulder, watching him in the mirror.
“Sieun, I don't like this,” Suho admits to him softly, still staring down into the sink.
Sieun stays quiet. Fingers prodding at Suho's waist lightly.
“I don't like choking you or slapping you on your face like that, it’s messing with me.”
Sieun nudges his head at Suho’s armpit and Suho lifts his arm so he can come underneath, now with his temple resting on his collarbone.
“Why?”
Suho looks up in the mirror, and Sieun catches his eyes there.
“I don't like hurting you, Sieun-ah. Honestly,” he pauses, and then he looks down at him instead. “It kinda turns me off actually, I just…” he trails.
I just don't want to do that to you. I can't.
“You're not hurting me, though,” Sieun assures him, softly.
Suho’s eyes move to his right cheek, where it’s still a little red. It's going away slowly.
“I like it, Suho.”
He's saying this like it'll ease the unfamiliarity in Suho's hands.
“I know you like it, and I’m telling you that I don't enjoy it, Sieun,” Suho tells him, gently, because he doesn't want to hurt his feelings.
And he hates denying Sieun literally anything.
But, he really just cannot do this.
“You’re my baby, Sieun,” Suho whispers, and his hand comes up to cup Sieun’s cheek that he just treated so meanly.
"I can't treat you like this."
His eyebrows are furrowed again.
“I know you like it, I know you like it rough, but I don't think I can keep up with you on this one, baby, I’m sorry.”
Sieun just stares at him for some time, his mouth in a slight pout. Pretty eyes looking contemplative.
“Okay,” Sieun murmurs. “Don't apologize to me. I feel like I should be apologizing to you.”
Suho shakes his head, “No, Sieun-ah, you don't have to apologize for being so…” Freaked out. “Kinky.”
Sieun’s mouth opens a little. “Kinky?”
Suho smiles a bit, his thumb gently rubbing against all that rushed blood to Sieun’s sweet cheek.
“Where do you store all this, Sieun.”
Sieun fixes his face from his dumbfounded expression and his features melt into their natural state again, shoulders shrugging up and down.
“I dunno. But, you bring it out of me, I think.”
Suho could write a ten page paper arguing that he does no such thing. No way.
“I’m so gentle with you, even when you want it rough, what are you saying?”
“I think that’s why,” Sieun softly answers.
Suho hums in confusion.
“Yeah,” Sieun says thoughtfully, moving his head to a tilt, into Suho’s palm. “Turns me on when you're even rougher with me after being so gentle.”
“I have to choke you and slap you in your face, Sieun?”
“No,” Sieun whispers, and he turns his face to kiss Suho’s hand. Same hand he used. “You don’t.”
“Are you upset?” Suho asks, “What if I can't satisfy you anymore?”
Silliest question of the century, has to be.
Sieun bites the plump section of his thumb muscle and bones in his palm before he lets off.
“Suho-yah, I said I like it a little bit, I didn't say you don't turn me on, hm?”
“Okay, so what do we do then, huh?” Suho moves around so he’s leaning back against the sink counter, and he brings Sieun in front of him by his waist.
“We just have the sex we’ve always been having, Suho," Sieun says, very plainly, almost flatly. "Why would this be a big deal?"
Suho mumbles, "Because I want to please you, Sieun."
"You please me constantly, Suho-yah. No matter what."
Suho feels elated with those words.
Sieun leans onto Suho, kind of pressing Suho’s back a bit uncomfortably into the edge of the sink, but Suho doesn't mind. His forearms are on Suho’s chest, fingers drawing lines and loops on his collarbones.
“You’ve been waiting to tell me this, and I don't like that.”
Suho keeps his hands rubbing on Sieun’s waist, gently pinching his skin there, massaging his fingers into his relaxed muscles. Going a little past the waistband of his boxer briefs and tracing his hip bones.
“I didn't really know what I was feeling when you asked me to for the first time," Suho responds, softly. “Just knew it didn't feel good. I don't like hearing you make those noises when you're getting choked, Sieun. At all."
Sieun's eyes are big and searching while he blinks and listens.
“And I especially don't like this mark on your face, from my own hand. I don't care that it'll fade. It shouldn't be there. And I really hope nothing shows up on your throat, Sieun-ah."
Suho lifts his left hand again, caressing Sieun’s cheek, which is almost back to its normal blush, because, really, he refused to do it too hard.
“You're my baby,” he emphasizes again. “I barely like giving you hickies because they just look like they hurt you, baby,” Suho continues, and now his other hand is on Sieun’s throat, his thumb pushing into his skin a little bit, feeling those bones he loves.
He wants to treat these perfectly crafted bones in Sieun's throat, the muscles, nicely. They help his baby breathe.
He wants to make the round cheeks of Sieun's beautiful face blush sweet pinks and reds from his words and his kisses, not his hands.
Next time Suho tries to find Sieun’s eyes, they're closed. And his mouth is agape, tongue hanging in between, lolling around a bit.
Suho presses his thumb a little more against the lymph nodes in his throat, where the sides of his jaw and his neck meet, and Sieun lets out a shaky breath.
And suddenly, Suho feels him filling up on his thigh.
“Baby.”
“I’m sorry,” Sieun murmurs, still with his eyes closed, because Suho certainly hasn't moved his soft hand on his throat.
“Don’t apologize,” Suho whispers, and he’s feeling himself start to stir too, because it's just inevitable, truly. “I can’t keep up with you, baby.”
Sieun’s lips curl up, and he opens his eyes again.
“I’ll slow down then,” Sieun says.
Suho tilts his head.
“Mhm,” Sieun hums, solidified. He brings one of his hands up to Suho’s face. “I’ll slow down, Suho-yah, I want us to be together. Through everything. Even if that means you won't choke me and slap me around while you're fucking me."
Suho snorts a little bit at the change in tone from the beginning to end of his confession. He hums at him though.
“We already have really good sex, Suho. You’re so gentle with me, even when you're being rough, and I think I got a little curious lately. I still like it, but you don't have to do all of that.”
Suho leans down and kisses his nose. Sieun scrunches it after, which just makes Suho want to kiss it again. So, he does.
“I just love your hands so much,” Sieun mumbles, while Suho’s still pressing little kisses to his nose, his cheeks. Especially his cheeks. “But having them on me is enough. Like this. How you always do. It really is.”
Suho hums again, and he moves so that their mouths are together instead.
A sweet kiss, for the moment. They massage each other's lips with their own, trading off soft sucks and bites of bottom lips, and whose tongue gets to do the leading. It turns their hips into a slow roll and grind.
“I get carried away with plenty of things,” Sieun murmurs into his mouth, once they’ve pulled away just to breathe.
“You always bring me back, Suho, always.”
He does. Suho always brings Sieun back down to where he needs to be, grounding in a completely different way than Sieun grounds him.
“That turns me on even more," Sieun says, and he leaves a tiny kiss on the corner of Suho's mouth. “Can’t you tell?”
Sieun knows he's Suho's baby. And he loves that more than anything, how safe Suho makes him feel, and cherished.
Suho blushes from the gentle praise, and he feels Sieun against him just as hard as he is, the two of them riled up just by being sweet and understanding of each other.
By listening and loving so deeply.
Ready to take each other apart again, after helping each other stay put together.
Same book, same pace. Always.
Maybe there's a kink for that.
