Since I've realised I have a cuckquean kink now I suppose I should write something about that
Nsfw/18+
Something something Emperor! König marrying you, the prince(ss) of another nation. Unbeknownst to him though, is the fact you are very much asexual.
It was a realisation you had as a teenager after sneaking into a brothel to see just what everyone was whispering and hiding from you. What you saw was... interesting.
On the one hand, you could appreciate the sight, the sounds, others pleasure. On the other though, the thought of being touched, of having a man inside you...
That you could not do.
Thankfully, your new husband has many concubines.
Originally, König was ready to be loyal to you– at least until an heir was born. After that, he'd allow you to take a few lovers too, if that is what you wished. But those plans go out the window when, on your wedding night, you explain your preferences awkwardly.
"... so, you don't mind if I still use my concubines?"
You shake your head. "No. I... I can't do what they can. It's only fair."
The emperor mulls it over, a thought coming to him.
"You cannot do it, no," he said, carefully cupping your face, "But you like to watch, yes?"
You gulp, face hot now as you stare up at your husband. "I... I suppose I do. Why?"
And that's how your wedding night is spent. You're sat delicately on a settee, drinks and snacks set for you as you watch with blushing cheeks as your new husband fucks some of his favourite concubines. You think some might become your favourites too, especially the black English boy, Kyle, and the silk-adorned Korean, Horangi.
Kyle had looked so pretty under König, wrecked and teary eyed; likewise, Horangi had been fierce yet beautiful, scarred yet soft as he rode his emperor wildly.
Even when he is surrounded by women kissing and sucking him, you just bask in the view, aching between the legs. Just because you cannot stand to be touched by someone else, doesn't mean you don't pleasure yourself on occasion.
König catches sight of you doing so while he's buried in a dark skinned beauty, a pair of redheads caressing his muscles and kissing his neck. His eyes widen, pupils dilating even more. He spreads the girl's legs wider, her head dangling off the edge of the bed. When he lifts her hips, you can see his cock disappearing into her slick depths, the wet smacks echoing in the room.
It covers up the soft sounds coming from between your legs as you rub yourself to completion, utterly entranced by the sight in front of you.
You hope this will become a common occurrence. You'd never dared to hope you'd find pleasure in your marriage, not when most men would sooner mount you than let you do your own thing.
Though based on the way he moans while holding your gaze, cumming in the girl, you think your new husband enjoys this arrangement as much as you.
Y'know who'd be perfect for a cuckquean fic? Sukuna.
NSFW/18+ (cw death)
Like think about it. You're his lover, his wife, yet he's still got all these concubines– young, beautiful women who serve him day and night, some by force, enslaved when he slaughtered their fathers and brothers and stole them away; others more willingly, having nowhere else to go. Better to serve this monster than starve on the streets or burden their family.
Obviously, when the title of "concubine" is slapped onto them, they know what to expect. Men have needs. Men as large and strong and as dangerous as Sukuna even more so. And, if rumours are to believed, the King of Curses has two cocks– further proof his needs are greater than the average man.
So it becomes commonplace for the girls to be called to his bedchambers to service him. Sometimes nightly, sometimes only weekly. They assume the nights none of them are called to service him are the nights he spends between your own thighs– his wife.
They don't see the lady of the temple often, Sukuna secreting you away. An odd sign of possession, for a man so disloyal. Then again, men aren't known for their loyalty to a single woman.
There's always an anticipation in the air when they wait to be called, girls whispering to each other about what they've heard or what he's done to them. Some girls whisper about those that went missing after visiting the king's rooms, but they pay little care for those tales. It's well known their lord is a temperamental one, after all.
Finally, Uraume arrives and looks upon them. The concubines arrange themselves, knelt, all looking as pretty as possible; sometimes, their lord allows his most loyal servant to choose for him.
Uraume looks to Akari, then, before nodding.
"You'll do for tonight." They say, and Akari preens, shooting the other girls a smirk as she follows. The others just glower jealously, and how could they not?
Akari was beautiful. Tall and lithe, with round, heavy breasts and an ass that had a slight jiggle to it– perfect for their master to bounce on his cocks.
She follows Uraume to the king's bedchambers, entering without preamble. There, as expected, she finds Sukuna sitting on the bed, naked, dicks already hard.
What is unexpected though is your presence off to the side, lounging on a sofa and plucking your own nipples, eyes heavy-lidded and focused on her.
Akari freezes, unsure of what to do. Yet Sukuna growls out a command for her to come, and so she does, shrugging off your presence for the time being.
Your eyes are like weights on her skin as you watch your husband touch her. Akari almost blocks you out when you say, "How does she feel?"
Sukuna hums, groping her breasts roughly. "Soft," he says, his other hands gripping her ass, squeezing and spreading her cheeks; is it just her, or is he adjusting her for you to see? "It feels like I'm playing with silken clay." He rumbles before taking her nipple into his mouth.
Akari moans, eyes slipping shut. On the sofa, you pinch your nipples, biting your lip.
"Is she wet?" You ask breathily.
He slips a hand between her thighs. "Dripping." He answers, lifting his fingers to show you the drooping strands of slick.
You watch as he sucks his fingers clean, moaning quietly. Akari feels distinctly uncomfortable, like she's not even there as Sukuna touches her and you ask him about her.
"How does she taste?" You ask, stroking your thighs. "Sweet? Tangy?"
Your husband shoots you a sharp grin.
"Better than you," he purrs, making a show of licking his lips. You make a sound at that, almost pained.
You slipped your fingers into your folds.
Akari just stared in confusion, shocked at this turn of events. What was happening? She'd never heard of wives watching their husbands betray them– nor husbands putting on such shows for their wives!
Even when Sukuna laid her out like a feast and went to town on her drippy pussy, it felt like all the attention was on you. Two of his eyes were pointed at you, even as the other two rolled back in pleasure as he moaned into her cunt, slurping on her clit and acting like she was the best thing he ever tasted.
All the while you watched, rubbing your clit, pussy loud as Sukuna cheated on you.
When he rose up, cocks gripped tight and pushing into her, you shoved your fingers inside your own cunt, a poor imitation of his fat shafts.
"How does she feel?" you ask breathlessly, frigging yourself to his pace. Sukuna growled, hips snapping against Akari's ass faster.
"Tighter than you," he grunted, choking the drooling concubine, making her moan weakly. At your whimper, he smirked. "So much tighter. I'm afraid your old cunt has gotten quite loose, wife. Perhaps if you didn't want me straying, you should try doing some exercises, make your cunny tight again."
You cry out, rubbing your clit fast and hard as you approached your climax. Seeing this, Sukuna sped up, fucking into Akari faster and faster before finally stilling and dumping his load in her.
When he pulls out, she's trembling, whining.
"But I didn't—"
She didn't get the last words out, Sukuna sending a Cleave her way. She went limp immediately, head rolling off.
As the both of you panted, struggling to find your breath, Sukuna wiped himself clean.
"Did you enjoy yourself, wife?" He asks almost sweetly, smiling when you nod, tired and satiated. "Good, now let me have a turn with the actual best cunt I've ever fucked. This one was barely satisfactory."
Thinking about older step sis Valeria cucking and bullying you.
Obvious NSFW/18+
The cucking doesn't happen until a while later. But the first few months of your parents' marriage is spent with the older girl making it known how pathetic she finds you, how much she hates you yet loves messing you with.
Borrowing your things without permission, wearing your clothes, eating your snacks–
Even using your toys.
Finding your dildo sat on your bedside table instead of where it should be, glistening, still wet with her arousal.
As you stare in mortified disgust, her voice rings out behind you.
"I made it better, zorra." Valeria says, smirking and leaning against your doorway. "Bet it tastes better now, too."
Despite the way you cuss her out and slam the door in her face, a shameful part of you considers it, of sucking on the toy she'd had inside her moments ago.
The cucking obviously only starts once you get a boyfriend: Alejandro. You'd never even suspect it with the way they argue in front of you, but of course, your stepsister can't let you have nice things... at least not without testing them herself.
Alejandro slipping out of bed in the middle of the night for a drink, only for Valeria to press up against him, tantalizing and tempting.
Alejandro coming to pick you up from work but when he does Valeria is in his car and it smells like sweat and something else...
Alejandro being full of guilt yet Valeria makes him swallow it along with the taste of her cunt, riding his face and soaking his beard and later watching him kiss you, knowing he hadn't had time to wash his face.
You only catch on when you finally catch them.
In your bed.
They don't even stop, Valeria turning to grin at you as she rides your boyfriend like a cowboy, telling you about all the things they'd done together until you're teary eyed.
And yet, you still stand there.
After he's cum in her, she pulls off, laying back and spreading her legs.
"Come, zorra," she coos, spreading her lips apart. "Clean me. I know you want to."
And shamefully, you do as told, kneeling between your stepsister's thighs and licking your boyfriend's cum from her pussy, Valeria holding you there and grinding against your tongue until she cums again.
