Chapter Text
When you open your eyes again, you squint at the dim light from the ceiling lamp.
You're lying under a thin duvet stuffed with synthetic foam. Standard issue in the cabins of a mid-range spaceship. You turn your head and see Sukuna's broad naked back no more than a few centimeters away from you.
He breathes deeply and evenly, snoring softly. The sleep of a man who must be fully satisfied with himself and the world.
You close your eyes and yawn heartily. Actually, you only wanted to rest for a moment, not take a full-blown nap. How long have you been sleeping? You groan and lean on your forearms, letting your gaze drift through the sparsely furnished cabin. No clock. Of course not.
Your legs feel like rubber; your labia, vagina, and especially your butt feel slightly sore. Saliva, semen, sweat, and your own moisture have dried into a sticky mixture. The skin on your arms, your lower belly, inner thighs, and scalp itches unpleasantly.
As hot as the past few minutes – or were they hours? – may have been, you have to wash yourself.
Quietly, so as not to wake Sukuna, you roll out of bed. Your muscles protest indignantly; the backs of your thighs sting as if you had a nasty muscle ache.
And then you freeze.
Something is leaking out of you.
In the first second, you try to remember when you last had your last period – just two weeks ago. Way to early to bleed again.
Eyes wide with disbelief, you look down at your still reddened labia, a milky white liquid dripping from between them.
Sukuna's semen.
On your tiptoes, you walk to the small door behind which the toilet and shower are located. And then you hurry back and grab the bar of soap Satoru gave you.
When Suguru had his first rut here on the ship, Satoru's enthusiastic moaning and grunting could be heard all the way to the main corridor on deck 3. Satoru's moans were accompanied by a constant wet slapping and Suguru's pressed baritone. Their noisy lovemaking was interrupted by occasional announcements from the ship's AI, which used its muffled, electronic voice to point out that taking showers too often put too much strain on the ship's water resources. ‘Ruts and heats’, Satoru said later, ‘are equally messy. Everyone with an ounce of sense in their head would shower in between or at least do a quick wash.’
That's probably why he gave you the soap; from personal experience.
Sukuna is lying on his side, his facial features relaxed. Behind the closed eyelids, his eyeballs move back and forth. The two additional eyes on his cheekbones have closed again.
You can't help but stroke his hair. Some strands, dark from sweat, stand out from his head in a mess. With your fingertips, you trace the dark marks on his forehead, cheek, and chin.
Although he is lying on his side, his cocks bulge the thin blanket. He wasn't exaggerating when he said that a permanent erection is the normal state during the rut. You bend down to him and kiss him on the forehead; on the pattern of black lines above his brows.
It resembles the pattern between the ears of a tabby cat. Sukuna grunts in his sleep. You grin and a warm feeling bubbles up in your stomach and chest as you scurry back to the bathroom, leaving a trace of tiny white drips behind you.
On an open shelf, there are two large paper-thin towels. They will probably just about be enough to dry you halfway. Four cryptic symbols flash on a small display next to the shower cubicle. The last two are identical to the symbol in the elevator that Yuji selected. A circle with a dent on top. The sign for 3.
33 minutes and some hours. Time plays only a minor role in space anyway. It is always dark, sunrises and sunsets do not exist up here.
Only speed and distances in light-years are important. Nevertheless, you would be very interested to know how long you have been down here with Sukuna. You feel like a whole day could have passed already. Maybe after your shower you could snuggle up back to Sukuna and, after he wakes up, you could have sex again. Maybe in spooning position. He could try to fuck you with both dicks at the same time. The perfect ending for a perfect day of screwing and rutting.
“Computer, how much time has passed since I first entered this cabin?”
The ship's AI reports via a small loudspeaker embedded in the wall above the shower head.
“Three hours and forty-six minutes have passed since you entered cabin 2-A-19."
The soap falls out of your hand.
Not even four hours?
Your pussy contracts in shock. Not even a sixth of twenty-four hours? For the first time, you actually consider taking the sensor blockers that Satoru, in wise foresight, also gave you. Being taken by Sukuna for another twenty hours seems increasingly like an almost insurmountable mammoth task.
Stunned by this new information you step into the shower and turn on the hot water.
The smell of chlorine hits your nostrils, but you don't care. The warm water is a relief for your tense muscles and itchy skin. The shower cubicle is spacious and floor-level, with walls lined with tiles made of hard plastic. Even Sukuna, with his broad back and four arms, could soap himself comfortably here without his elbows touching the walls. You lather up the soap and wash yourself with your own hands, for lack of a washcloth.
And then you try to get out what Sukuna has left in you.
You gently push two fingers inside you. It stings a little and at the same time feels strangely familiar. When you pull your fingers out again, milky white fluid is stuck to them. You have no idea what Ryomen semen is made of, but it is definitely thicker than human ejaculate.
You breathe out with effort, lean your back against the tiles, spread your legs and carefully finger yourself. Diluted by the pouring water, more and more comes out of you. The area between your butt cheeks has also become suspiciously sticky.
“Need some help?”
You flinch and pull your fingers out of you. Sukuna is standing in the doorway, grinning smugly down at you. “You're dripping”, he says, and you're absolutely sure he doesn't mean the shower water.
“And whose fault is that?”, you shoot back, blushing bright red. The Ryomen is slowly approaching. There are traces of sleep on his cheek from the pillow. He must have just woken up. Then he stops and nods in you direction, looking questioningly at you and the shower head.
You give him credit for at least having the decency to ask you first if he can join you. You move aside and Sukuna slides into the shower cubicle with you. He leans down and kisses you on the forehead while the warm water splashes down on his neck and back.
These forehead kisses must be the equivalent of kisses on the mouth for Ryomen, as often as he does them. You stretch up on your toes and kiss him on the lips in return.
“Did you sleep well?”, he asks.
You nod and hand him the bar of soap. Sukuna sniffs it and makes a disgusted face. With a foreboding look, he presses his nose against your neck. "Tch, you smell like Satoru...”
“He gave me his- ah! his soap", you mumble.
Sukuna snorts discontentedly and runs two of his wrists over your soapy upper arms. The other two hands land on your hips and draw small circles there. “I don't want you to smell like him”, the Ryomen growls. “I want you to smell like me.”
His fingers on your arms slowly move to your cheek and grasp your chin. He kisses you, becoming more and more passionate and demanding.
His cocks are at half-mast. The upper one pushes against your lower abdomen, while the other rubs over your mons pubis.
“Can you take both at once?”, he suddenly mumbles against your temple and pushes his wet loins against you.
The question is unmistakable and you secretly wondered when Sukuna would ask you. The idea of being fucked by two cocks at the same time has been haunting your mind since the moment Yuji revealed to you that Alpha-Ryomen have two penises.
But the only logical and reasonable answer would be a 'No'.
Your reddened labia, clitoris and vagina are still burning at the edge of their limits. Not to mention your butt. But your libido-driven brain has other plans; as if a switch has flipped inside you, lowering all your thinking to the level of a horny Stone Age woman: consequences later. Sex now!
Without further ado, you reach between Sukuna's legs and stroke his hard flesh. A tense smile twitches at the corner of his mouth; his nostrils flare up. You pump his upper cock until it is fully erect again and the wet tip nudges against your clitoris again and again.
“I've fantasized about it since I knew you had two of them”, you answer truthfully. ”When I was doing it to myself, at the very beginning, when you surprised me, I imagined that I was riding one of your mouths. That I was riding the tongue on your belly and you were licking me with it until I came.”
The Alpha snorts voluptuously and pushes you against the tiled wall. He lifts one of your legs and wraps it around his hip. Balancing on one leg, you try not to fall on the slippery, wet shower floor.
As he kisses your neck, he shoves his penises between your thighs and against your pussy. His upper cock slides between your labia and rubs against your folds. His second dick pushes between your wet thighs.
You throw your head back, accidentally bumping the back of your head against the wet tiles.
A loud gurgling sound comes from above.
Both of you look up – just in time to see the last drops of water dripping from the shower head.
>>Water supply of cabin 2-A-19 depleted. If you require additional water, please report to the captain or to a member of the crew. We kindly ask you to use our resources sparingly and to consider alternative cleaning methods if necessary. We thank you for your understanding and wish you a pleasant flight.<<
The muffled, mechanical voice of the AI falls silent.
Motionless and soaking wet, you stand on one leg at the shower wall, Sukuna's cocks bulging and damp between your labia and thighs. Stunned, you look up at the Alpha. He returns your gaze.
The water tank is empty. And you are still standing in the shower with a few remnants of soapy foam on your bodies.
“What the hell are alternative cleaning methods supposed to be?”, you ask into the steamy silence of the shower cubicle.
Sukuna looks at you – and grins.
You wrap your arms around Sukuna's neck and kiss him vigorously. The Ryomen has his hands around your bottom and pushed you up the wet shower wall so far that your vulva is just above his loins. His upper penis presses between your butt cheeks like a constant reminder that it and its twin are just waiting for their move.
You moan hoarsely against his mouth. He has interlocked the fingers of his other two hands with your own fingers and presses your hands against the shower wall above your head.
It's a grotesque sight: where Sukuna's belly button should have been, there's just a long, wide horizontal crack. A mouth has opened there, similar to those in the palms of his hands. But this one is bigger. And the tongue of this giant maw is also bigger – and longer.
Your head is spinning.
The mouth is wide open, its tongue sticking out. Breathlessly, you try to rub your clitoris against it, but the angle is wrong. Frustrated you squirm in Sukuna's grip, bury your face in his and nibble on his shoulder. Then you jump in surprise as the tongue meets your pussy, pressing flat against your vulva and licking up what is still leaking out of you.
Alternative cleaning methods, my ass!
You moan against Sukuna's shoulder and rub your clitoris against the velvety surface of the tongue, whose broad tip teases your entrance.
“Just so you know”, Sukuna whispers breathlessly, licking your neck. ”What you just fingered out of yourself, I'll fuck back into you later. And I'll fuck you— hah!—until you don't smell like that fucking soap from fucking Satoru anymore!”
You sigh against the crook of his neck and kiss with an open mouth the approximate spot where his pheromone glands are. When you try to pull your fingers out of his grip, he firmly pushes your hands back against the wet tiles.
Sukuna watches with fascination as his human slithers towards her orgasm. His blood throbs in his loins, his cocks are so hard that it's starting to get uncomfortable.
The smell of Gojo's soap doesn’t cling to her anymore. Good. He would make sure she would only smell of him; of his pheromones and of his cum and of her own scent, which isn't that of an Omega, but similarly intoxicating.
She jerks her hips awkwardly, trying to ride the tongue on his abdomen, wet from saliva. It's sexy and wicked at the same time, the way she struggles and pants as she rushes towards her orgasm. Her cheeks are flushed from the hot and humid air.
This time he wants to watch her come.
The tip of the tongue slides heavily and moistly through your folds and presses itself against your clitoris.
You gasp for air. This time, when you move your hips and Sukuna holds your bottom, tingling pleasure shoots up your abdomen. You grind against his tongue faster and faster and more and more greedily. You close your eyes and bite your lower lip. Heat and greed build up inside you.
Your clitoris is throbbing.
You open your mouth for a silent moan.
And then you come.
It's a hot but short orgasm. A wake-up call to the last sleepy cells in your body, telling them to get ready for what's coming next.
The Ryomen carries you out of the shower. You're hanging in his arms with trembling legs and because you don't know what else to do with yourself except to breathe out your orgasm, you kiss and suck at the black marks on his chest.
Sukuna puts you on your shaky legs and quickly rubs you down with one of the towels. As he turns you around and dries your back, he also cups your left breast with one hand from behind and pinches your nipple with two fingers. The nipple, soft and puffed up from the warm water, hardens immediately.
You sigh and let your head sink on his shoulder. You’re not ready for another orgasm – not yet.
Sukuna presses his naked chest against your back and throws the towel on the floor as he wraps two strong arms around your middle and heaves you back onto the bed.
Seconds later, you are kneeling upright at the foot of the mattress. He is standing behind you, kissing the back of your neck. He has a firm grip on you with his two lower arms, while the other two hands are still on your tits, stroking, kneading and squeezing the soft flesh.
You hold on to his lower arms. His biceps are tense; a vein runs across the twitching muscle. And then something hard and moist presses against your thighs from behind.
The Ryomen shoves his hips forward and the reddened glanses of his two cocks pushes between your thighs from behind. He thrusts again and shakily breathes out. Fascinated, you look down at yourself, at your thighs, the soft insides of which are being slowly fucked by Sukuna.
Following an idea, you push your knees together. The alpha behind you grunts in surprise as his cocks suddenly slide up a bit between your legs and nestle against your wet labia. You squeeze your thighs together and shove your pelvis back whenever he thrusts forward.
The tip of his longer cock peaks through the triangle your pussy forms with the small gap between your thighs.
Sukuna hisses softly and kisses your neck. Clear pre-cum coats his tips and makes it easier for him to fuck your thighs. Your own wetness, as well as the residual moisture from the shower, do the rest. You rub your folds against his hard cock and the swelling of his knot, panting softly.
It feels good.
Incredibly good.
So good that it carries you away on a wave of endorphins, but it’s not intoxicating enough to make you cum again after such a short time.
Still, his unadulterated moans are like a drug to you; he's blown your brain out of your skull and fucked you four times. At least this one time, you want to return the favor; you want to listen to him losing his mind over how good you make him feel.
Sukuna's movements become jerkier and faster. Two of his hands lie flat on your breasts as his mouths in his palms open again, licking over your nipples and sucking on them.
You gasp blissfully and suddenly an idea comes to your mind and you don't know whether it's a brilliant or a ridiculously stupid one.
“You were right“, you say quietly, turning your head to the side. Sukuna's mouth is close to your ear. He nibbles on your earlobe, but stops immediately when you begin to speak.
“What?”, he asks, his lips touching your outer ear as he speaks.
“No one has ever fucked me as well as you have. You feel so incredibly good.”
You can even hear his grin through his laboured breathing. “Of course, after all, I am-”
“I've been trying to imagine what your knot would feel like inside me. When you'd push it into me until it won't go any further. And how it would feel when you'd shove both of them into me at once. You're big and your knots just touch all the right places in me. It felt so hot both times before. And later I want to sit on your cock and ride your knot until I cum. And I want to kiss you. I love kissing you. And I want you to fuck my mouth the same way you fucked my pussy. I'd like that. I would really like that.”
Sukuna doesn't reply anything. For a moment you're unsure whether you've just taken the wind out of his sails or whether dirty talk just isn't his thing.
On the opposite, he fucks your thighs as if possessed, teasing your inner, wet labia. So you continue:
“After this I want us to do it again in the shower. Standing against the wall. And then I want to suck your dick and give you a blowjob until you come. And I want to see you losing your mind.” You keep talking, revealing every fantasy you've had about Sukuna in the last few days. Scene after scene unfolds before your mind's eye, making you hot and thirsty.
Sukuna's breathing quickens. One of the mouths in his palm sucks hard on your nipple and your areola.
You gasp uninhibitedly and caress his tense upper arms.
“And later, I want you to take me from the side. With both cocks at once. And then I want to ride you while you finger my clit at the same time. I want to ride the mouth on your belly and-”
“Shut up!”, Sukuna groans and presses one of his hands over your mouth. The cocks between your thighs are as hard as a rifle barrels. They’re throbbing and since he is thrusting faster and faster and without any rhythm, he must be about to come. ”You have no idea what you're saying! Earlier you've already had to tap out after only two... ah, rounds! Fuck!”
You open your mouth and press your tongue against the mouth in Sukuna's palm. As if it had developed a life of its own, it returns the kiss. You breath against his fingers. It's a unique kiss; the tongue is wetter and smoother than normal tongues. But that's what makes it so hot.
“I don't know if I should- should find it hot or weird!”, Sukuna groans and flinches slightly as you suck on the tip of his tongue.
You press your knees further together, trying to create more pressure and friction between your thighs. Not just for him, but also for you and your throbbing clitoris. Again you’re drowning in tingling heat and Sukunas own heady scent of black pepper, lavender and sandalwood mixed with the smell of sweat and sex.
Sukuna thrusts two, three, four more times frantically between your thighs and comes. Milky-white, warm cum smears between your thighs and splatters onto the bed sheet in front of you.
Behind you, Sukuna moans through gritted teeth and savors his orgasm to the full. He thrusts a few more times before he leans against your back, removes his hand from your mouth and gives you a slap on the right butt cheek.
“Do you need a moment?”, you ask him provocatively. The ryomen snorts and gives you a push between the shoulder blades. You fall forward, landing on your stomach on the mattress.
The Alpha climbs onto the bed to you and sits on his heels.
Hastily you roll around on your back.
He kneels between your spread thighs; although he has just come, his cocks are semi-hard. The knots on both shafts are slightly swollen. He begins pumping them both back to life with powerful movements, while he looks at your hard nipples and your wet, shiny cunt with greed in his eyes.
Actually, Sukuna's stamina should worry you. He came between your thighs not even a minute ago and is still – or again? – hard.
You watch as he rubs himself, as the two reddened and cum-smeared glanses repeatedly push out of his fist. If you didn't know how he would react, you would have put a hand between your legs and fingered yourself. Maybe it wasn't such a good idea to provoke him like that.
With a driven glow in his red eyes, Sukuna looks around, spotting the tube of lubricant lying dented on the sheet. He hastily snaps the cap open, squeezes a generous portion into the palm of his hand, and continues to masturbate.
With his other two hands, he grasps the back of your knees and impatiently pulls you closer to him.
You try to swallow down the lump that has formed in your throat. You feel giddy, heat and lust bubble up in your abdomen and your belly.
“So you've tried to imagine what my knots would feel like inside you, hn?” His voice sounds hoarse and excited at the same time. He guides the reddened tip of his upper cock to your cunt, slides it between your labia and over your throbbing clitoris. ”You'll find out in a moment.”
He presses the tip against the entrance.
Okay, it’s happening, no worries, just relax, you try to calm yourself down and fail miserably. Lust and anticipation are killing you. You want more but at the same time you are not so sure if you’re ready for more.
As he penetrates you one or two centimeters deep, you close your eyes and sigh softly.
With his other two hands, which are wet from lubricant, Sukuna grabs your butt cheeks and jerkily pulls you closer to his lap. His upper cock penetrates you deeper and then you feel the slippery, moist tip of his second cock at your twitching anus. His fingertips dig into your bottom possessively and spread your cheeks apart.
You feel heat rising to your face. The Alpha looms over you like a statue. You let your gaze slide down his body: his red eyes and his handsome features, his hairless chest with the black tattoo-like markings and down to the trail of faded pink hairs leading down to his loins.
His second cock squeezes trough your twitching muscle ring. You gasp for breath.
Pressure. A lot of pressure. Hot pressure.
“Look at me,” the Alpha whispers above you. You blink up at him and let out a surprised moan as the Ryomen shoves his hips further without warning.
He stakes you with his two dicks – and you like it.
“Look. At. Me,” he repeats; the grin in his words brings you back to reality for the moment. He lets go of the back of your knees and runs one hand up your belly. The other approaches your clitoris; his thumb nudges sideways against the sensitive spot and starts circling it.
You flinch and open your mouth to a long, breathless moan as Sukuna fondles your clit. At the same time he thrusts his hips forward.
Hot and heavy and wet, his cocks pierce you further. You feel full. Although ‘full’ is quite the understatement. You can feel his dicks in your abdomen, in your belly, in your core. And then there's a resistance. His enlarged knots press against your entrances, stopping him from pushing deeper.
“Go on. Move,” you stumble over your words, wrap your legs around his hip and cross your ankles behind his lower back.
Sukuna snorts with amusement. But he doesn't move. Instead, he leans over you, propping himself up on the mattress.
The angle changes. His upper cock slides a bit deeper into you. You can feel the swelling of his knot at your entrance all too clearly. The lower one pulls on your rim.
Sukuna's face hovers just centimeters above your own. His warm breath brushes across your forehead. He kisses you between your eyebrows, then presses his lips to your mouth.
You meet him halfway, nibbling on his lower lip, brushing against his tongue.
Sukuna shoves his hips forward with a single sharp thrust. You choke on your own breath but the sound is lost in your shared kiss. Slowly, he withdraws his dicks. As Sukuna thrusts into you again his movements starts to quicken and you wrap your arms around his broad back.
His lower cock pushes and pulls at your muscle ring with every movement.
His upper cock plows through you, thrusting and drilling into you again and again and stretching you with its size.
You feel both of them inside you. Big and heavy and hot. Like two pistons. When Sukuna pulls out of you, it feels strangely empty, but when he thrusts back in, you feel like you're stuffed to the brim.
“More,” you mumble breathlessly against his chin, secretly knowing that you will regret it later. “Give me more.”
The alpha turns his head to the side, presses his lips against your ear and whispers dirty sweet nothings to you.
That your pussy is wonderfully tight and warm. That you're a good little human, taking his two fat cocks at the same time. That he will ruin you for every other man and every other Alpha. That you feel incredibly good, that you taste incredibly good. That he wants to see you squirm on his knots when he shoves them right inside you. That he will fill you up with his cum until it drips out of you again.
You moan; your cheeks turn red with shame and arousal.
Sukuna adjusts his knees further apart; the swelling of his upper cock half enters your vagina and stretches your entrance almost too far. At the same time, the knot of his lower dick pierces fully into your ass.
“Oh God!”, you gasp in shock and surprise. Everything inside you contracts, becomes hot and dizzy. Your muscle ring twitches around the knot, trying to adjust to the size. Your thighs start to tremble.
Sukuna swallows dryly and mumbles a few syllables under his breath, but so quietly that your translator chip can't make them out.
“You also feel good!”, you reply, not having a single clue what he actually said. The Alpha nestles his sweaty upper body against your breasts and sloppily kisses your throat. You dig your fingertips in his broad back. His skin is slightly sweaty; you can't get a grip on it.
Sukuna withdraws his dicks and thrusts them back into you. He shifts his weight on top of you and starts fucking you for real – he pounds hard and fast into you. His wiry pink pubic hair rubs over your clitoris, every time he thrusts into you. Tingling heat clenches in your cunt, fanned by the Ryomen. And with one quick, sharp thrust both knots drill into you at the same time, taking your breath away. The jolt shoves you up a few centimeters on the mattress.
Big, way too big!
Your vision get blurry as tears gather in the corners of your eyes. You hold on to him for dear life and can't do anything but lie under him and let him fuck you. The swellings irritate your entrance and your muscle ring, each time they slide out of you and then back into you, they pull at your inner walls.
Heat and pressure contract inside you, the tip of the upper cock digs deep into you, his pubic hair and lower belly flatten your swollen clitoris.
You moan.
Unable to grasp any thoughts, you nibble on the crook of his neck.
And as he forces his knots into you again, you bite him on the shoulder.
Simply because your fingertips on his sweaty back aren't enough to ground you.
Sukuna swears unhinged and groans and pounds into you again and again with short, jerky movements. His upper knot grinds over your G-spot. The lower knot stretches your ass. Both are still growing and make it more and more difficult for him to move inside of you. Which also means his thrust become harder and even more powerful. It's too much of everything and not enough at the same time. Your head is spinning with lust and horniness.
He rears up in your grip, grabs the back of your knees and pulls your legs off his back. He shoves your thighs up and presses them against your chest. He folds you in half like wet laundry. The new position has you completely exposed. With a sharp thrust he plunges back in impossibly deeper. Your body jolts; you choke on your own lust and horniness, moaning and groaning. He resumes his unhinged pace.
“Tha- aaah! It’s too- too deep”, you babble, the friction and depth making you mind blur. Your lower abdomen is tight; your overstimulated nerves are ready to snap as he thrusts into you relentlessly.
“That’s the point”, he pants out. You feel like your’re melting underneath his body. Your overstreched legs start shaking.
The sound of skin slapping against skin makes you dizzy as he steadily brings you closer to the edge of another mind shattering orgasm. Maybe this is it; this is the fan fiction worthy smut you so often read about. You risk a glance, watching as the upper half of his cock, the red swelling of his knot, plunge into your cunt with a lewd squelching sound.
It’s almost too big for him to move.
Almost.
But it's definitely too much for you to look at.
You mushy mind spirals further down into overstimulation. It felt like the world had been narrowed down entirely to Sukuna fucking you with his two fat swollen cocks.
“If- ah! If you’d be an Omega, I would keep you! I would take you back to Ryoma. And fuck you every- every evening. I would fuck you so good, that all of our neighbors would hear your desperate mewls and screams for my cocks. I would keep you in my house and fuuuh! Fuck a whole litter of brats into you. To show everyone that you are even better than an Omega and that I am the best A- Alpha!”, he groans, continuing with his fast pace as he chases after his own high.
His groans become more frequent and louder, his grip on your butt and hips tightening painfully and his thrusts slightly losing their rhythm. He’s breathless, his movements become more desperate and rough.
His words send shivers down your spine. You pull his face down to yours; you kiss him with a desperation that you should have been embarrassed about. Sukuna moves on top of you and slides one of his hands – you don't know which one – between your bodies. You moan even before his fingers have reached your clitoris. He pinches the swollen nub between two fingers, strokes it again and again with even movements; teasing the small fold of you clitoris hood.
You squirm und tremble and mewl underneath him. “Su-sukuna-aah! Ah! Don’t stoo- aah! Don’t stop!”
He doesn't stop; he continues to tease your throbbing clitoris, jerking his hips back and forth. You close your eyes, let yourself go, alternately kissing and panting against his shoulder.
Your orgasm crashes over you like a tidal wave, burns your insides and sizzles through your core. You moan and groan and try to say something, twitching around his cock – his cocks – and the two knots.
He pounds a few more times inside you and then he pushes his cocks one last time with full force between your legs and comes, too, pumping his cum into you twice.
His knots swell further, preventing him from withdrawing from you. He fucks you through his own orgasm with short, sharp movements, plowing through your clenching and pulsating walls.
You moan, claw at him, and let yourself be carried away by your orgasm.
His knots pull at your wet inner walls, rubbing mercilessly over your G-spot.
Sukuna continues to finger you, only stopping when you are lying beneath him, weak and twitching and exhausted.
That wasn't sex. That was madness, a smutty real-life porn, defilement.
The Ryomen was right when he said that you would never forget this moment – would never forget sex with him. His cocks pulsate, nestled snugly and hot inside you. Still pumping sperm into you.
Your heart is beating like its fighting for its life. You can feel your own blood pumping in your ears.
Sukuna lays on top of you, groans slightly, and lets go of your legs. Your limps slip from his shoulders like dead weights.
He leans closer, kissing you deeply as though he wanted to devour you. You both pant heavily into the kiss, lips pressing sloppily together with sighs dragged out of your chest and ragged breaths from his throat.
“Are you still alive?”, he asks you after a while.
You shake your head.
Sukuna huffs in amusement.
“I don’t know… Asks me again in half an hour. But- can we cuddle?”
Sukuna smile is warm and honest as he carefully lays on top and snuggles up to you. His knots are still stuck in you like two hot and pulsating plugs. Every reckless move from his side drags at your entrances and sends hot sizzles through your overstimulated system.
Once or twice you flinch but as soon as the Ryomen hugs you with his four arms and nuzzles up to your side, you sigh contentedly.
You spend the next couple minutes kissing and caressing each other. And then comes the unpleasant part: The Alpha pulls his soft and deflated cocks out of you and you instinctively clench around his soft flesh. The sudden emptiness feels wrong.
He embraces you and turns over onto his back with you in his arms.
“That was the hottest and toughest shit I have ever done!”, you say after a while as you listen to the soft drum of his heartbeat. “In a very good way.”
The Alpha hums and kisses your forehead. You return the action, interlacing your fingers with his.
“I’m still fascinated by your human body”, he says lost in thoughts and looks at your interlaced fingers. “Even though you are no Omega, you have some similarities. You said human women have no clamps but there was something in you that made you lose your mind whenever I touched it.”
“Erm… this is called the G-Spot”, you say and try your best to remember the correct terms. “It’s the spot where the inner part of the clitoris touches the vagina.”
Sukuna raises his brows. “It’s not only the nub down there?”
You shake your head and feel the heat returning to your cheeks. You didn’t expect to give some sex education to an alien right after he fucked your brain out of your body. “A clitoris looks like the letter Y.” You try to recreate the character with your fingers. “The visible part is the single end of the Y. And where it touches the vagina it so to say splits up into the two ends of the Y. I hope you know, what I mean.”
The Ryomen nods, falls silent again and slowly caress your back with the tips of his fingers.
The next eighteen hours pass endlessly slowly and at the same time incredibly quickly. After you have more or less recovered from his two knots, Sukuna becomes restless again. Even though you thought the last fucking would have worn him out as well, his cocks are ready to go again.
This time he fucks you against the wall. You're in his grip and can't do much more than moan and mumble incoherent syllables. He presses his mouth to your throat and sucks on the crook of your neck.
When you both come and you slide down the wall in his arms, Sukuna sits on his heels and takes you there a second time. You dig your fingers into his back while he bounces you on his lap.
As a grand finale, he licks you until you come twice more.
After another nap, which feels more like a dreamless deep sleep, Sukuna snuggles up to you from the side and takes you in a spoon position. It's not as wild as before, but more gentle and loving. You try to kiss him over your shoulder. When that doesn't work, he covers your mouth with his hand again and you kiss his palm and suck on his tongue there.
Then you ride the tongue on his belly, rubbing yourself to orgasm, only to lie on your stomach minutes later, impaled again by Sukuna's two cocks at the same time.
Your brain is nothing more but a hot spinning mess of incoherent thoughts and moans.
He fucks your ass again, sucks on your nipples until they are hard and red and wrinkled.
And later, after another short nap, Sukuna no longer has a full erection. One last time he takes you in the shower, the tank of which has been filled up with the new daily water ration.
And then the remaining hours of Sukuna's rut are over. Snuggled close to him, you fall asleep. Your body feels hot and tingling all over, and – you can't deny it – you are quite sore down there.
But at the same time you feel very, very satisfied.
“What does a spaceport actually look like?”
“Hm... most spaceports are either decommissioned space stations or minor planets that are towed by several big space harbor tugs. There are terminals, landing bays, hangars, departments for cargo flights. All sorts.”
“Sounds like a huge airport. Just different.”
Sukuna lets out a sigh, but he doesn't say much more. He's lying on his back, arms and legs stretched out in front of him, looking just as exhausted as you. You're spread out next to Sukuna under the synthetic duvet, head resting on his naked chest. After another shower, and another reminder from the AI that you're wasting precious water supplies, you lay in bed, bathing in the afterglow.
This cuddle session feels different. There's no obvious desire for more intense physical intimacy. There's no pressure or intent behind touches and soft kisses. It's intimate, but in a different way. It's like one of those lazy sunday mornings where breakfast is served in bed and nothing needs to be taken care of.
One of his hands lies on your naked hip under the heavy blanket, a second plays with your hair.
"Do you think we could find someone to take me back to Earth?"
At first Sukuna doesn't answer. You lift your chin questioningly and look up at him. The Ryomen looks at you with furrowed brows, as if trying to figure out how to deliver bad news in the gentlest way possible. Your courage sinks. Without a word, you rest your cheek against his bare chest.
The Alpha lets out a sigh.
"Officially, it's strictly forbidden to go to your planet," Sukuna says. "Humans are classified as an underdeveloped species. In fact, underdeveloped species are not allowed to be contacted."
"And yet that doesn't stop the flesh traders from taking humans as slaves," you reply bitterly.
"That is exactly why humans are so sought after on the flesh market and command some of the highest prices. You humans are one of the few other species that are considered underdeveloped and therefore cannot be contacted or enslaved... At the same time, you are humanoic enough to be considered suitable slaves. They're considered "rare goods" because it's illegal to own a human. And that's the problem. We're sure we can find someone willing to break the rules of interplanetary travel and fly you to Earth. But there's no way to guarantee that whoever's flying the ship won't change their mind halfway there and sell you out again."
"What if I came with you and Yuji? To Ryoma? Could I live there?"
Sukuna is silent again. And this time you take his taciturnity personally. For a thought begins to eat away at your brain like steaming nitric acid. "Is there someone waiting for you in Ryoma? Do you have a wife? Children?"
You never asked him about his marital status. And Yuji didn't mention that he had cousins. But the mere thought of it is enough to cause all kinds of bad thoughts in your mind - especially since you just had what must have been breathtaking sex with him.
But Sukuna (thankfully) shakes his head and pulls you closer to his chest.
"I'm not with anyone, I'm not married and I don't have any children. It's just that you wouldn't be happy there. On Ryoma."
"But I would be with you and Yuji."
"That is not the point. Ryoma has had close trade relations with the flesh traders since ancient times. One of the biggest auction houses for slave trade is located in Heian, the planetary capital. It's not that I don't want you with me. It's just that you won't be safe on Ryoma. You'd be considered a slave, a replaceable piece of meat. And I won't have that."
You press your face into his neck. His scent of black pepper, lavender, and sandalwood is comforting, but it also makes you wistful. So saying goodbye would be inevitable. Except for... "What if I go with Satoru and Suguru to their planet? How far is it from Ryoma? Can I visit you?"
The Alpha rolls his eyes and snorts with amusement. "Satoru would be thrilled. He's been cackling like a hen in heat around Megumi for days. They'd be really happy if you came with them. Then they'd have a nanny for Megumi... Shibuya Tau is one of the, I think, eight or nine moons of the planet Shibuya. The planet belongs to a solar system in the same sector as Ryoma's system. In theory, that would work. You could visit Yuji and me."
"Why are you so against Satoru?"
"Satoru is a miserable snob who thinks he's better than everyone else. I just don't like him. He doesn't like me... Anyway, Shibuya Tau doesn't have its own slave system anymore, but from what you said, it's hardly comparable to Earth. People there are even more stubborn than on Ryoma when it comes to maintaining relationships. Alphas are only allowed to bond with Omegas, Betas only with Betas, and anyone who deviates is severely punished."
"I used to think that aliens were super advanced and that things like slavery or discrimination only existed on Earth."
Sukuna laughs briefly and humorlessly, lifts your chin and kisses you on the forehead. "We will find a solution. We still have some time and no matter how this story ends, I just want to enjoy it now."
You murmur in agreement, curl up next to Sukuna and stroke his bare chest. "Tell me, how often do Ryomen actually have a rut?"
The Alpha opens his eyes. "About every three or four months. Why?"
"Oh..." you say, not quite able to keep the disappointment out of your voice.
"Would you like to be fucked by me more often?"
"Maybe. I just want to know where I stand right now. With you. Will everything be the same when we join the others later? Or can we... well... get to know each other?" you answer, feeling the heat rising in your cheeks. You're acting just as awkward as Yuji with his clumsy approaches towards Megumi.
Sukuna frowns questioningly. "Get to know each other?"
You squirm on top of him, struggling for words and becoming more and more awkward because you don't know how to break down what's going on inside of you into words and sentences. "When people have sex and want more from each other, they usually get to know each other. They go on dates. Maybe... maybe we can do that. Get to know each other. And... have sex again... only if you want to, of course."
If the ground had opened up at that moment, you would have jumped in with joy. Your cheeks are terribly hot, your whole head glows like a lantern.
And Sukuna has nothing better to do than laugh. "You humans act like frigid pussies when it comes to normal things like nudity or sex. But at the same time, you have no problem kissing someone you barely know on the mouth."
"What does that have to do with anything?"
"Kisses on the lips are something very intimate. At least for Ryomen and other species with secondary genders. Only couples who are bonded usually do that. Even Satoru and Suguru only kiss when they think no one is looking."
"That's why you were so irritated when I kissed you for the first time."
"It just took me by surprise. But I'm not complaining. I like kissing you. I like it, it feels good. And to get back to your question: yes, I want to fuck you again. Out of my rut, too. And yes, I want to get to know you. Even though I'm not exactly sure how you humans "get to know each other."
You smile and kiss him, straddling his waist. "Don't worry. I will show you." You sit up and look down at him.
He grins and crosses two of his hands behind his head. "I really like you, you know," he says leisurely. "Even though you have no pheromone glands and are not an Omega."
"And I like you," you say. "Even though you are an alien with four arms, extra mouths in weird places, and two giant cocks."
