Work Text:
Sukuna hums, looking at the small floating flower bed in the park he and Satoru are walking by. It's a gorgeous day, their daughter is at school, and they're taking a nice break from the rest of their obligations. To be fair, they're practically paid to be alive. But Sukuna still has to have meetings with his superiors.
How the child is doing. How his mate is doing. The alien and the little mutant child.
And Satoru has his lab. And studies.
Sukuna looks up at his mate and chirps thoughtfully. "Satoru, do you think we should take up any of those offers by the way?" He doesn't elaborate any further than that.
Satoru blushes. Honestly, he's surprised they've been given space walking through the park together. Sure, people stop and stare, but they haven't had to stop for any photos.
"Hmm." He pretends to think about it for what he deems to be the appropriate amount of time. Then he shrugs. "Why not? For research purposes, I'm quite curious."
"Research? Right. Definitely not that you're horny and want to feel big compared to another Asarian." Sukuna jokes as they turn around a corner with a pretty waterfall. There's someone a bit down the path, coming toward them, but Sukuna doesn't look closely. If they want a picture, they'll ask when they're closer.
"I am big," Satoru huffs, "and you love it." It's been too long since he's had Sukuna creaming on his cock, shoving his own inside because it’s so tight. Having Sayuri at home makes it hard to find time for just the two of them.
He sighs. "I miss being inside you." He misses Sukuna getting high and forcing him down, riding him until his dick feels like it's going to fall off.
There's a surprised clicking chirp that draws Sukuna's attention up to the person walking toward them. A purple Asarian with black antennae and tail walks up to them with a friendly smile. "Ryoumen, pleasure seeing you off station." His marks glow a faint yellow as he glances at Satoru quickly. He looks away and he clears his throat afterward.
Sukuna pauses in his teasing to look at the newcomer. "Geto?" Sukuna hums, "This is a co-worker of mine, Suguru." He explains as he tightens his tail around Satoru's thigh.
"It's nice to finally meet you." Suguru has a fox-like smile and he tilts his head just enough to move his hair gently.
Satoru stares back. He can't help but take in the readings he gets from his visor. The numbers flash, so quickly he'd not be able to read them if he didn't have cybernetic eyes.
"Oh." Slowly, he smirks. "Is it?"
Is he one of those co-workers? Satoru feels like a slab of fine meat, and he likes it.
Suguru tilts his head as he hears the human speak, and then a translator sounds out from... probably his visor, or the device he has on his wrist. He read about the specifics in what files he could find, but it's different seeing him in person. He's tall and so very foreign looking.
"Yeah, I'm honoured."
He wonders if Sukuna mentioned that time he propositioned him. Them technically. He's not sure if he'd be mortified knowing that they both knew, or if he'd just accept it and soldier through. They probably deal with offers like that all the time.
Suguru gets caught up thinking about it for a few seconds too long, staring at Satoru.
It goes right to Satoru's head, and he beams, wrapping one arm around Sukuna to hold him close (not that he'd be able to escape if he wanted to, with how tightly Sukuna's got his tail wrapped around his leg).
"Your markings. I'd love to know what the compound is in your epidermis that makes them gold."
"You had to be a science nerd about his skin?" Sukuna complains and looks between them. Suguru looks kind of charmed honestly. Sukuna leans in closer, "You know that thing I just mentioned, Satoru?"
"Yes?" Satoru looks between his mate and the newcomer. Interesting. So this is one of the Asarians that wants to, well, experience him. His suspicions have been confirmed. "I'm down if you are."
What a Satoru way to agree to it. Sukuna purrs and tilts his head at Suguru, "Remember when you asked me if you could watch or join? Are you free right now?"
Suguru almost chokes on his own spit. "I-" He pauses and looks between them, gaze lingering a little too long on the human. "Yeah... I'm free." When he purrs back, it's lilting, like a song. "Where?"
"We could go back to our place?" Satoru suggests. "Sayuri won't be home from school for a few hours." He can't believe he's actually doing this, fucking someone other than his mate.
"Good." Sukuna hums and gestures at Suguru to follow. Then he pauses, "As long as that's fine with you?"
"It's fine, as long as your kid's not there and there aren't cameras." Suguru laughs and follows, on Sukuna's side. He keeps glancing at Satoru as they walk, "You'll have to wear the device that translates for you right? Unless Ryoumen-"
"Sukuna."
"Unless Sukuna wants to translate everything."
"I don't." Sukuna chips in again.
Satoru watches the two of them interact with fascination. He wonders if they're like this at work. The more he thinks about things, the more he thinks maybe they should have Geto sign an NDA or something.
"Well, let's get going then. No need to fight, there's plenty of me to go around."
He catches onto the way Geto is looking at him.
Sukuna rolls his eyes at Satoru, but he walks a bit closer to him. No matter how much he's okay with this whole thing, it's new and he's not quite sure how to deal with it. But Suguru seems relaxed, and very interested in Satoru. A brief thought flashes through Sukuna's mind that he'll be on the sidelines, but he pushes it aside. He'll make sure he isn't. If he has to push Suguru down and ensure his own participation, he will.
They make it back to the house and Sukuna lets them in. "Satoru, can you bring him to the bedroom? I don't want to chit chat."
Suguru barely has any time to admire the place before Sukuna's trying to send him to the bed. He does notice some of the decorations are odd, like they shouldn't exist. Maybe they're the human aspects?
"I should have guessed you'd be like this... Exactly like work." Suguru sighs at Sukuna, then looks at Satoru. His breathing picks up and he tries to remain calm. It's hard with the curious excitement under his skin.
"Right this way." Satoru motions for Suguru to follow, after kicking off his shoes. His heart is already beating a little faster, cock warm in his pants as it fills with blood. It's exciting.
"So how long have you worked with Sukuna?" he asks after they make it inside. He pulls his shirt off over his head and tosses it near the bed, blushing, but he can't help it. He steps forward enough, into Suguru's personal space, to give him the unspoken permission to touch.
"Since I was stationed at-" Suguru trills and his hands twitch, looking at the expanse of pale skin, the muscle shapes that are just slightly different from Asarians. And his nipples. Mammal. Right. He swallows thickly. "For about six years." Suguru manages, but it's strained.
Slowly, his hands reach up and he touches Satoru's ribs first and he wraps them around his sides, and then back to the front. He trails down his abs, eyes tracking his own hands studiously. When he reaches his pant line, he moves back up and over his chest, then over his collarbones and around his shoulders.
"Do humans kiss?"
Sukuna walks in and leans in the doorway, watching, his slit is already puffy, and he can see that Suguru's is too. "They do, and his tongue is different. He's good at it." Sukuna walks up behind Suguru and he nuzzles the back of his neck. He mouths at him and purrs softly. "Show him."
Satoru holds the back of Sukuna's head while he kisses Suguru. He licks into his mouth and moans at the feeling of another's tongue against his own. They're chest to chest as well, and Satoru is insistent on pressing his erection into Suguru.
His body knows what to do, even with a non-human the reaction is strong. He's about to fuck and he knows it.
"Good," he whispers when he pulls away, kissing along Suguru's jaw, then his neck. "Did you tell him how I fuck, Sukuna? Does he know that it's rough?"
"Now he does~" Sukuna coos as he kisses down Suguru's spine.
"Rough? I can do rough." Suguru says a bit too fast, but then he tries to compose himself. The kiss was different, but nice. Satoru's tongue is shorter and thick. "How rough?" His cock is sliding out and he keeps looking down. He can feel a hardness in Satoru's pants that he's not used to. It's big. His pussy and cock are a deep black with a few small yellow dots on the underside of his length. They match his tail and antennae.
Satoru grabs Sukuna's ass with one hand and slips the other down Suguru's front and to his slit where his cock is undulating freely. He lets it slide against the veins in his wrist while he feels out his opening and sighs at how wet it is. He doesn't quite push inside, but Suguru could take him in if he angled his hips enough.
"You'll be sore tomorrow," he says.
"I can handle that." Suguru’s cunt vibrates and he shifts just enough to push Satoru's fingers into him. "I-" He moans softly and his cock wraps around Satoru's wrist, "I want that." He has a small grin.
Sukuna wraps his hands around Suguru's hips and he presses along his pelvic bones, down to where Satoru's fingers are inside. Sukuna spreads Suguru's pussy and bites his shoulder enough to bruise. "Good." He sucks on the skin after and gets a surprised moan in return.
Suguru turns his head and kisses Sukuna as he breaks away from his shoulder. Their tongues curl together and stroke leisurely.
Satoru groans quietly as he watches. He's the only one wearing pants, so after rubbing on his dick a little he decides to take them off and steps back from Suguru to start sliding them down his thighs. He leaves his boxer briefs on, for now, and steps back to sit on the bed, watching the two Asarians tangle up together. He wants to see their cocks touch.
Sukuna glances, and then mumbles when he notices Suguru's attention drifting to Satoru. "Doesn't he look good? You should see under those. He's hard and so thick. You might not even be able to take it." Sukuna kisses down Suguru's neck and tangles his fingers in the tendril like cock of their bed partner. "His cum tastes different too." He whispers into Suguru's ear. "He loves it when I use my mouth on him. Do you want to try?"
Suguru inhales deeply and his cock twines around Sukuna's fingers. He can't look away from Satoru, but he can't hear anything other than the blood rushing in his ears and Sukuna whispering to him. He groans and nods, "Yes, please ."
At Sukuna's pleased noise, Suguru walks forward and drops to his knees between Satoru's legs. He rubs up and down his legs, his thighs, marvelling at the hair. "Can I?" He looks up at Satoru with wide eyes and a little smile. His fingers slide up and rest on Satoru's waistband.
"Shit," the human curses under his breath. He looks at Sukuna first, then back down to Suguru. His visor comes off before his underwear do. "Watch your teeth," is all he says before he starts letting Suguru peel his underwear off.
His cock stands and twitches towards his belly. He doesn't touch it, simply sitting back with his palms flat on the bed, knees spread a little wider to show off the best that human genitals have to offer.
Suguru's eyes widen and he trills softly, fingers twitching, wanting to touch. Slowly, his hand reaches and he wraps his fingers around Satoru's base, wetting his lips and looking up at the bionic eyes studying him. His cock is velvety smooth and there's no slick to glide through.
He pumps his fist slowly up to the tip and he marvells at the flared head. Just as his fingers smear through the precum, Sukuna kneels behind him, pushing Satoru's knees further apart and grinding against Suguru's back. His hands reach into Suguru's hair and he pulls almost all of it back so the couple can get a clear view of Suguru's face. "Try not to choke." Sukuna says with a dark smile.
With a shaky exhale, Suguru's tongue slithers out and he curls it around Satoru's tip. His eyes close and he makes a surprised noise at the taste. Then his lips close over the head and he suckles.
Satoru throws his head back and lets his eyes close. He licks his lips slowly while Suguru's tongue works around his swollen tip. "God, yeah," he breathes. "Fuuuck, that's good. Take me deeper."
He wants to hit the back of his throat, but he doesn't start fucking up into his mouth, not yet. Sukuna would probably get mad if he came so quickly.
Suguru moans at Satoru's encouragement and starts bobbing up and down, his tongue sliding along his shaft. On each thrust, he gets deeper. It's a bit of a struggle for a moment, but then Suguru sinks to Satoru's base and purrs, nuzzling into the hairs there with a surprised hum.
"No gag reflex." Sukuna marvells. He's a bit jealous that Suguru takes Satoru's cock so easily. He remembers how hard it was for him at first, and he looks up to see his mate's face. To see the expression he's making.
"Oh- Sukuna," Satoru moans. His eyes are closed but he hopes that he's watching his cock disappear into Suguru's throat, that he can see the bulge. "Oh god- Careful." He grabs Suguru's hair when it starts getting really good. "Fuck, you could make me cum so fast like this."
Sukuna exhales shakily and he puts a hand on Suguru's throat, to feel Satoru thrusting in and out. "So good Suguru, do you want to make him cum?" Sukuna ducks in close, pushing Suguru's head down, forcing him. "Hold your breath and let him use you."
Suguru whines and drool drips from his lips as he ruts his hips into the air. He's dripping obscene amounts of slick on the floor and all he wants is for the human to fuck his throat. He nods just enough, pleading.
"Show him, baby."
That's all it takes for Satoru to start fucking into his mouth, chasing his orgasm until he's pulling silky strands of black hair and grunting out a string of curses. His cum comes out in thick streams, and he hunches over the head in his lap. "Ah, ah~ You take it so well." It's almost like he's feeding it to him.
The taste makes Suguru's brows furrow, but he swallows diligently. He won't get sick from eating it, hell the stuff impregnated an Asarian. But his throat constricts as he swallows and then he grunts. Sukuna hasn't let him off yet.
Sukuna smirks and pulls Suguru back by the hair and the throat, popping off Satoru's cock, and immediately kissing him. Tasting Satoru on his tongue. "Up." Sukuna stands, pulling Suguru with, not being gentle in the least. Then Sukuna's pushing Suguru until he's on his back on the bed. Sukuna grins and climbs up his body.
Suguru looks pretty with his hair fanned out under him, and Sukuna grinds their pussies together, wrapping his cock up with Suguru's and moaning softly. "Maybe we'll both fuck you. If you can stretch, you can take us at the same time." Sukuna looks over at Satoru and he pulls him over for a kiss as he grinds on Suguru's lap.
"You're so hot," Satoru mutters with a dopey, fucked out grin. The first orgasm left him gooey-brained and warm, now he just wants to be close to his mate.
He looks down at Suguru, watching his body twitch and move, and their cocks tangle together. It's so different from the way humans have intercourse, but beautiful in its own way. He can already feel himself start to throb again.
"You should get him warmed up for me, 'kuna."
"You want to watch?" Sukuna purrs, a little smirk on his face as he untwines their cocks and he shifts his hips. "See me fuck him? I'll make it a show just for you baby." And his cock slides up and down through the folds of Suguru's pussy, earning a small gasp.
Then Sukuna exhales on a moan and his cock pushes inside. His hips grind against him and Sukuna rocks a bit like Satoru does, but his cock is stroking and curling against Suguru's walls. "You're going to be so good for him, so tight and wet. Maybe I'll cum in you and let him fuck my cum out." Sukuna rests his hands on Suguru's chest as he rocks his hips.
Suguru moans and opens his mouth to speak but he doesn't make a sound. It takes him a few seconds to compose himself, slowly grinding up into Sukuna's rolling thrusts and he sighs. "Let me take both-" It's quiet, like a prayer. “I can take it.” Begging to be filled. He arches his back and his cock slides down and slips inside himself. It winds up around Sukuna's and starts to squeeze and pulse, vibrating and undulating.
"Fuck, yes , just like that." Sukuna gasps and bites his lip, eyes falling shut as he pants and writhes his cock inside Suguru's cunt.
Satoru fists his own length as it starts to harden up again. He's desperate to be inside of someone, whoever it is. He kisses Sukuna's shoulder and the back of his neck, encouraging more.
"I think he needs to get fucked the human way. But I don't know if he could take it. Do you want both of our cum, Suguru? I won't hold back."
"Fuck-" Suguru curses and arches just for Sukuna to push him down again with a tut. He's not sure where to put his hands, so he reaches down and holds Sukuna's hips. "Don't hold back. Break me."
Sukuna moans brokenly at that and he leans so he's flat on Suguru's chest, "Look, Satoru, taste us together." He kisses Suguru, and then bites a mark on his neck and sucks.
Settling between their legs, the human moves forward with his tongue out and ready to swipe through both their exposed cunts. Suguru's full and oozing a mixture of fluids. It's just as sweet as he'd expected it to be and Satoru groans, he licks inside of Sukuna, fucking his tongue into soft heat, deeply kissing his pussy.
When he sits back, he swipes the head of his cock between the folds, dips inside of Sukuna just enough to wet it. With the two Asarian cocks still tangled inside he pauses, asks, "Can you take all three?" and lines his dick up, just a sliver of an inch away before he starts forcing his way inside. One pussy on top of the other, he watches Sukuna's clench around nothing and moans. "Oh, hell-"
There's a tandem moan as Sukuna's markings light up in sync with Suguru's. "Oh fuck, baby!" Sukuna grunts and he writhes, trying to move his cock just a bit to give Satoru more room.
Suguru gasps loudly and he makes a low vibrating sound like a purr. "Shit! Fuck-" His cunt tightens, then relaxes, then tightens again, trying desperately to decide if it wants Satoru's cock or not. If it wants to listen to Suguru's brain and let him get ruined by these two.
"Wait, wait, slow, fuck please, shit you're so fucking big. So hot, I can't-" Suguru pants and writhes under Sukuna, trying to get closer and away all at once.
Sukuna pauses after a harsh breath, "Do it, Satoru. Make him take it." His cock vibrates to try to stimulate Suguru's cunt into loosening even more.
No breaks and no slowing down, Satoru stuffs his entire shaft inside and he's sure that it's bordering on painful. The squeeze is heavenly. Suguru's walls feel slightly different than Sukuna's and he fucks into the plush, soft flesh, barely managing to keep his eyes open with how far gone he is, fallen into a hazy, sex drunk stupor.
"You said I could break you," he pants, and tense as his hips rock mercilessly. He can't fuck too deep at first, just an inch or two of movement while the pussy he's locked inside gets wetter, looser, opens up for him like Sukuna always does. "Fuck, there. Just like that. Ugh, I can't wait to cum in you."
He's taking, he's not giving at all. His pace quickens to brutal and the sound of skin slapping against skin fills the room.
Suguru keens as he's stretched so full he feels like he's ripped apart, but the pleasure doubles, no, triples , as Satoru slams into him. He chants a string of curses, markings bright and heart rate spiking as he's dragged forcefully toward an orgasm that he's not sure if he's prepared for. His cock spasms around Sukuna's and he cums with a shout, thrashing and sobbing on the tail end. He goes lax and hazy as he wraps his arms around Sukuna and kisses him.
Sukuna shudders at the squeeze and the pace, and the cum, and everything . He sways his tail, enticing Satoru to pull as he sucks on Suguru's pliant tongue, watches him drool as he pulls back. Sukuna stutters a gasp and his cock makes a ring inside of Suguru's cunt, just for Satoru to fuck into. He tightens it like a vice and purrs.
"Fuck!" Satoru shouts, his thrusts don't stop, he works Suguru all the way through his orgasm, and reaches out to yank on Sukuna's pretty red tail. "You're perfect for us," he breathes. "A perfect hole for us to fuck in- hah-"
Sukuna's tendril is snug around him and it only makes him harder, hornier. He forces apart Suguru's legs even wider, his whole body gets pushed further up the bed with each thrust.
"I'm gonna cum so hard in you." He barely manages to get the words between hard breaths before he slams in as deep as he can and his cock starts shooting out semen.
Suguru groans low in his chest and his eyes roll back. He smiles and touches up and down Sukuna's back, kissing along his jaw and down to his collar. "Can you cum in me too?"
Sukuna tilts his head to give Suguru more access. His dick jerks and milks Satoru through his orgasm and he curves his spine just enough to stick his cunt up toward his mate. "Finger me until I cum, Satoru. Or you can eat me out. But I like your cock in here."
The fingers that were wrapped around the base of Sukuna's tail are already making their way between his cheeks. He's soaking wet and easy to slide inside, two and then three. Satoru crooks them exactly the way he knows that Sukuna likes it, he fucks into him like he used to finger fuck him on the exam table. His cock twitches inside of Suguru and he rocks his hips a little.
"Show me, baby," he says. "I wanna see you cum around me."
Sukuna whines and rocks back, cock vibrating and tightening minutely. "I will- oh god." He mumbles and his cunt drips down onto Satoru. Then Suguru kisses him again, his antennae gently touching Sukuna's. They hum audibly and then Sukuna's moaning long and low, cumming around Satoru's fingers, and his cock.
Sukuna's pussy squeezes him rhythmically, gripping his fingers and keeping them inside. He feels the warm, slick fluid flood tight space around his cock as his own starts to leak out and drip thickly.
Suguru really is a champ, for taking so much. Satoru watches the back of Sukuna's head while they kiss and then he suddenly realises, "I need to take notes."
Sukuna stops the kiss with a wet pop and he looks over his shoulder.
" Seriously …?"
