"Hey Y/N I just wanna know something."

You look up to see Yuji stroking his chin, looking deep in thought. Oh wait no, he's just mimicking what people do when they stroke their chins dramatically. 

"Ask away Yuji," you said, sitting beside him. 

The two of you are let's say stuck at the school because the higher ups doesn't trust either of you to try to save the world. They still blame you for all that's happening and some old geezer is convinced that killing you will stop the tears and other realities potentially coming here to kill you all. 

And because you're now known as Sukuna's bride they're worried you're working with Sukuna to basically end the world. 

So while everyone out there is risking their lives to seal these tears, you two are stuck here. 

"Should I try drugs before I die?" he asked.

You blink as you look at him and turn back to your phone.

"No."

"Oh come on, what about alcohol?"

"Honestly alcohol is at least safer than drugs, but no." 

"Ugh but this could be my last shot!" Yuji groans loudly and slides his body off the bed and onto you. His head rests in your lap and your free hand rests on his head. "Yuji you're going to live until you turn 121 years old, you'll have plenty of time to drink or do drugs. Though I wouldn't recommend it, next thing you know you're eating someone's face if you're hyped on drugs."

"Drugs make you do that?!"

You look down at him with a 'for-real?!' expression. "Yuji you're asking me if you can do drugs when you don't even know how dangerous they can be?!" you asked, taken aback. "I thought you just lose your shit, not eat someone's face!" he screams, shocked.

"Don't forget you could lose your teeth and your gums will be nonexistent," you added, looking back on your phone.

Yuji grunts and crosses his arms against his chest as you run your fingers through his hair. "Nooo I need my teeth, how will I eat if I have no teeth." You snort and continue to play with his soft hair. You rub, gently tug, twirled his hair between your fingers and his eyes would flutter close, feeling like he's in heaven.

You scroll aimlessly through your social media, Youtube, fanfictions, nothing catching your attention. You just put your phone down and look at the ceiling bored.  You feel Yuji grab your hand and pull it away from his hair. 

"Hey what happened to your hand?"

You look down to see that he's examining your palm. There was little skinned marks and cuts as he traces his finger against them, gently. "Oh that, I was reaching for something and I skinned myself on something," you explain. 

The thing was you were actually reaching for your razor blade under your bed last night.

You were throwing it out. 

But it got lodged in the mattress so you had to painfully free it to throw it out. And it was a perfect opportunity when Yuji took over that night and wanted to hang out with Nobara and Megumi. It was worse because you had to look up to the roof, thinking of multiple annoying songs, and keeping your eyes closed so Sukuna could not see what you were doing.

You don't know if he ever knew, or if he was in your mind last night, but you sure as hell didn't want to explain it to him in case. 

You threw it out because...you don't need it. 

You know there will be times when your mental state will be down, but as long as you have those you love around you....

You'll be okay.

Yeah...you'll be okay.

Plus blood was everywhere so you also had to clean it up with your eyes closed and dispose of the bloody evidence as well. It was too much work.

"Darling why didn't you tell me you hurt your hand?" Sukuna's eye and mouth appears. "I could have healed you earlier." 

"Whatever it was it got you pretty good," Yuji mumbles, concerned. 

He let's Sukuna take over and the King heals your hand. "Honestly I forgot about it," you tried to lie only for Sukuna to cut you off with a glare. "Okay fine it hurts, but I usually just deal with pain like this."

"You usually deal with pain like this?" he repeats, his tone with disbelief. Okay so maybe he didn't search through your memories hard enough and saw you harming yourself, thank fuck. You mean thank god. "Princess what do you mean you deal with pain like this?"

You open your mouth to think of any excuse.

"I uh....have a knife kink?"

Sukuna's brow raises at your obvious lie. 

"Y/N you hate pain."

"I....just wanted to test it out. Like it's like um wanting to taste a different kind of chocolate ya know? I just wanted to see the appeal of...using a knife sexually?"

"But on your hand?"

You cannot lie to this man. He knows you get really nervous when you start lying. Instead you keep your mouth closed as he finishes healing your hand. Right now he can hear your heart race in panic.

Sukuna knows he can just peer through your mind and memories, but you look really uncomfortable with this topic. 

Through whatever remaining goodness of his heart he will not betray your trust like that. He wants you comfortable enough to come to him for anything. He knows he had violated through your memories enough as it is. 

"Alright whenever your ready to talk about it," he sighs. 

You smile softly, relaxing. "Thank you." You rest your head on his shoulder and he holds you. Wow it amazes you just how gentle he can be sometimes. You know he is not a patient man, but he's being patient for you.

Sukuna is dying to know what the hell happened though. It's eating at his mind, he needs a distraction. 

"Rabbit turn on a movie, you can't leave so let's at least do something," he grunts.

"What? You can't leave either!"

"Wrong, these sorcerers think they have me trapped here, but I can leave whenever I want to. I'm only here because you want to be a good girl and follow the rules."

"Hey breaking rules unnerve me."

"Rules are meant to be broken."

"You say that but then it'll come back to bite me in the ass," you grunt. "Whenever I tried to be a rebel growing up it always bit me in the ass. So I determined that I wouldn't break the rules.....as much as I can. I mean I already broke an unspoken rule."

"Oh what rule is that?"

You smile looking up to him. "Falling in love with the King of Curses." 

Sukuna smirks and looks up smugly. "Mm, so you are a little rule breaker, my baby is not so innocent." 

'Was never innocent with my dirty mind,' you thought.

'I can still hear your thoughts.'

'I know.'

Just with that thought alone it was enough to slightly raise your arousal. Without warning, you and him end up in his domain. 

You're sitting on his lap and he immediately pulls you into a rough kiss. You kiss back, wrapping your arms around his neck as his hands squeezes your ass. You gasp and he takes the chance to push his tongue in your mouth. 

Your hips grin against his cock, feeling his cocks harden immediately. That actually got you thinking...if he switches with Yuji does that mean two of his cocks are there too?

This is a serious question.

Sukuna halts when he senses your mind is elsewhere. "Darling?" You blink and pat his chest lightly. "Sorry sorry I was just thinking," you said, smiling. 

"Having second thoughts?"

"No I was just thinking....if every time you switch with Yuji do both of your penises come out with you?" 

It was his turn to blink slowly before he busts into laughter. "It's a genuine question!" you defend yourself as he laughs. "Here I am with my tongue down your throat and that's what you think?" 

"Well I just wanted to know! When the moment comes when I finally give you my virginity I know what I'm expecting."

"You want your virginity taken outside of my domain?"

"No offense, but giving my virginity on top of a bunch of skulls doesn't sound all that romantic. I want to lose it in a comfortable bed with just the two of us, not skulls. Now that I think about it..." You push yourself closer to him to avoid the skulls. 

"Did you like decapitate a bunch of goats to make your throne? And were they giant goats too?"

"You had no problem when I was eating you out in here," he comments, ignoring your question.

"I was laying on you!" your words shriek. "And sitting on you!"

He chuckles and cups your face with his large hand. "So you want it to be romantic?"

"That would be preferred," you giggle as he kisses you lightly. "But right now I want to try something." You get off his lap and kneel in front of him. His eyes widen a bit as you grip the hem of his pants. 

You grin as his cocks pops out of his pants. Sukuna can see the excitement in your eyes and before he can utter a word you immediately place one cock in your mouth. Your tongue swirls the red tip, licking up the precum leaking out. 

His other cock is in your hand, pumping it slowly. His voice is caught in his throat as you suck him as if you have been waiting for this for a long time. 

"Fuck darling," he groans.

His moans sent pleasured throbs in your pussy as you boldly try to take more of him in your mouth. His chest rises up and down as you look up to him, watching him if he likes what you're doing. 

You pull off of this cock and put the other one in your mouth greedily. Hearing his moans is giving you the confidence to keep going. Hollowing your cheeks, you suck harshly on the neglected cock.

"Such a good girl," he praises. 

Sukuna runs his fingers through his hair, gripping it hard trying so hard to not force you to take more in. He's struggling to keep his hips still because he knows he will choke you if he does or even hurt you. 

He sits up a bit when he watches you struggle trying to take him whole in your mouth. "Stop, stop," he growls, gently lifting your mouth off of him. "Don't hurt yourself trying to please me." 

Oh hell no you're not a wimp. 

"But my King," you moan lightly, both of his cocks in your hands. You feel both of them twitch in your palms.  Before he could stop you you suck him off again and this time dared to put him deeper in your throat. He growls and grips your hair, half trying to lift you off of him and the other half wanting to fuck your throat. 

You love that he cares for you, but maybe you just want to see the other side of him. The side you know he's hiding, the rough side. The only question is...is his rough side normal or does his rough side deal in the extremes? 

You suck, kiss, and run your tongue on the veins of his cocks. Sukuna snapped and his hips thrusted up while also pushing your head down.

"Look at you," he growls. "Sucking my cocks like a needy slut." 

Your moans are muffled as you feel your pussy throb. His growls and pants grow heavy and fast. "Good little slut, my perfect baby. You're so-"

With a final thrust he let's out a low growl as his cum fills your mouth and throat. The cock in your hand shoot it's load behind you as you try to swallow the load in your mouth. You whimper weakly as you pull back, some cum spilling out of your lips.

Your throat and mouth are sore, but damn did you love it.

"Where did you learn that?" he pants, watching you. "From how well you did, it's hard to believe you're a virgin."

"So....you know bananas?" you start, blushing a bit.

"You practiced on a fruit," he concluded.  Nodding, you licked your lips and wipe your chin clean with your finger and also put the cum in your mouth. The taste wasn't as bad as you thought, not your favorite but you didn't mind it.

"You always surprise me darling," he chuckles. "Now I want to try something." 

"Oh?"

"I want you to sit on my face."

Your face turns red and you suddenly feel very shy.

"I-I don't know," you spoke, nervous. 

"You don't know? I ate you out before." He looks confused by your sudden hesitation. You rub your hands, feeling your face burn. You want it, god you do, but now that the moment is here, you just feel nervous.

"Yeah, but sitting on your face? What if I suffocate you and kill you with my vagina?! I almost killed Yuji when my thighs crushed his head when we were watching those movies!" 

"I think I also heard you say people like to be suffocated. I didn't quite get what you meant at the time, but now I understand." He leans back, resting on his forearms smirking. "Baby sit on my face, you won't kill me I swear. And if I do that's....one way to kill the King of Curses." 

This made you giggle and it made you relax.

As soon as you feel his breath hit your pussy his hands immediately grips your hips in an iron grip and lowers you firmly on his face. His tongue immediately licks through your folds, making you gasp. 

You tremble on top of him as he sucks on your clit, lapping up your juices with his tongue. Hearing your needy moans, made him proud. Proud that his baby is so needy, so eager. 

"Ah Sukuna...shit that feels so..." 

You moan weakly, feeling your orgasm build up so quickly. Your arms and thighs tremble as he pulls back so he can chuckle. "Relax baby, it's okay." He soothes as your body involuntarily tenses up. It's just something that happens. You try to relax as his tongue licks between your folds all the way up to your clit. 

Your eyes widen when his tongue wiggles inside your slit. Something in your snapped and you sit up fully to grip his hair. "Ah Sukuna, daddy that's it!" you mewl. "Please..."

Your hips rut against his face, feeling your orgasm nearing. So close, you just need more. You don't even know what you need! 

But he does, he somehow knows what you always need.

He reaches to rub your clit as his tongue licks fast. "That's it baby, suffocate me with this pretty pussy." This sent you over the edge and you orgasm, hips weakly grinding against his face to ride it out. Your pants fills his ears as you wordlessly get off of his face. 

He smirks as he uses his finger to wipe your wetness off of his face and lick his fingers clean. You feel your body burn in embarrassment as his face is coated in your juices. But he just has a proud look on his face as he cleans his face. 

"I-I'm sorry I kind of lost it at the end there," you apologize. 

"The most important thing is that you enjoyed yourself," he hummed. "Now come here sweet girl." You lean against his side as he holds you. "I want to try something else." 

"No way, I already came I'm sensitive. I wouldn't handle it."

"You liar I've seen you orgasm multiple times a day in your memories."

"Okay but there was a resting period between those times!" you squeaked out, well more like shouting. He groans as you hid your face in his chest. Such a shame, he really liked the thought of your pussy clenching and squeezing around his fingers. 

There's always a next time. 

Again after cleaning yourself up, you two are enjoying each other's company. You sit on his lap on his throne as his hand rests on your hip while leaning into his hand.

"If we had children would you want boys or girls?" you asked him. 

"Preferably a son, but we can't really control that," he hummed. "I know if we ever have a daughter she'll be spoiled rotten."

"Aw you're going to spoil our potential future daughter?"

Sukuna lifts your hand and kisses your knuckles. "Regardless of the gender of our baby, I'm happy to have an heir. A king and a queen needs a prince or princess." 

"Damn who would've thought I'd be married into royalty," you said, excited. 

Sukuna reaches into his kimono and pulls out the music player you gave him. He hands you a bud but you shake your head. "I think I'm going to explore in here, not exactly tired yet."

"Let me help you down."

In the blink of an eye you're back on the blood floor and down from his throne. You smile and explore the area, nothing much to explore to be honest but you do tend to wander. You peek behind a rib to just see darkness and pout in disappointment. 

You look up to see Sukuna's eyes closed, both ear buds inside of his ears. Damn you wish you had your phone to take a picture. You smile and lean against Yuji's rib then get an idea. 

You start poking it, rubbing it, trying to see if he can feel it. Maybe even try to tickle him from the inside? 

"What the hell this isn't his funny bone it won't work," you mutter, disappointed. "Plus I can't even see if he's laughing or not."

-

Yuji groans as he wakes up in control again with his back pressed on the floor. He feels a weight on him and sees you're sprawled out on top of him. He knows that means you're in Sukuna's domain. He rubs his eyes and sits up, his arm clutching your waist as he lifts you with him. 

He's feeling a little tired, but he could go for some food right now. 

He lays you on the bed and walks to the door but halts. Yuji makes his way back to you and kneels bedside the bed. He watches you sleep, you hugging one of the stuffed animals Sukuna won for you on your first date. 

"I'll keep you safe, I promise," he mumbles. 

He smiles as you move in your sleep, maybe you're coming back soon from the domain? He'll make you some food too.

"We're ride or die buddies remember that, alright? If you jump off a cliff, I'm jumping with ya. If you're going to Hell, I'll follow you, you're my homie. And if we for some reason have to eat bugs or spiders...sorry you're on your own." 

He chuckles and places a kiss on your head then walks to the door. His hand grips on the doorknob, twisting it open then he turns to you.

"And for God's sake stop having sex inside of me!" 

He finally leaves the room and makes his way to the dark kitchen. He whistles a song as he opens the fridge and peeks inside to find some food. It's bare inside and he grumbles, not having enough food to make dinner. 

'Ah what should I do? I guess I can order something and have Gojo pick it up? Nah I wanna make something really delicious, maybe I can send him a grocery list.'

He quickly pulls out his phone and sends a lists of food he needs to
