Sukuna wasn’t a jealous being.
No.
Not him.
Ryoumen Sukuna the King of Curses.
Sukuna was just very protective of his host.
He never liked to admit that he cared for the dimwitted teen but unfortunately, he did.
The king of curses never had anything better to do normally than sitting on his throne and watching the boy go around and live his life.
Which is what he was currently doing…
Except for the fact that some people liked to touch the sweet and clueless teen a little too much.
Like the Jujutsu Sorcerer that Sukuna had a personal vendetta against.
Gojo Satoru.
The man had to audacity to just walk up and hug his host from behind or put his arm around his shoulder, and it pissed Sukuna off greatly.
Of course, his precious little Yuuji never said anything because he practically worshipped the man, though it’s not like he knew about Sukuna’s jealousy.
Protectiveness.
He didn’t get jealous.
“Yuuji!” Gojo whined to his host, tugging on the boys hand.
“Gojo-Sensei!” Yuuji laughed.
Sukuna’s hands tightened on the arm rests of his throne dangerously, hearing the stone crack under his fingers before it crumbled under the force.
“Shitty Jujutsu Sorcerer.” Sukuna grumbled, face turning down into a scowl.
“Let’s all go get some cake!” The toddler of a man suggested to Yuuji and his friends, draping himself across the boys shoulders.
That’s it.
Sukuna had enough.
“Shitty Jujutsu Sorcerer, quit touching what doesn’t belong to you.” He growled, mouth opening up on Yuuji’s cheek.
“Eh?” Gojo smirked, looking at the mouth on his students cheek.
“Sukuna! Sorry Gojo-Sensei he just pops out sometimes!” The teen apologized, covering Sukuna’s mouth with his own hand.
Sukuna smirked and licked across the boys palm, relishing in the disgusted shriek that escaped those perfect lips that he longed to kiss.
“S-Sukuna..!” Yuuji whined, a pretty pink blush coating his cheeks.
“Why don’t I get rid of him Yuuji?” Gojo smirked, looking at the mouth on his students cheek.
“No!” His host suddenly yelled, causing the curse to smirk triumphantly. The boy didn’t want anyone else to touch him, and that warmed a deep dark distant part of the his sick twisted heart.
“Why not?” Gojo questioned, looking at the teen worriedly.
“I-I…” Yuuji swallowed nervously, backing up a couple steps.
“I-I got it! B-Bye Sensei!”
With that, Yuuji quickly fled from his teacher, Sukuna’s mouth on his cheek disappearing. He smirked, pleased that he was wanted by the boy, and more than little proud of him for preventing that man from doing something to him.
“S-Sukuna you can’t do that…” Yuuji scolded pathetically.
Oh but why not? He was touching what was mine. I simply defended it.
“You were jealous.” Yuuji giggled.

“Listen up brat, though that may be hard with your two braincells in that thick skull of yours. I wasn’t jealous. I don’t get jealous. I’m the king of curses, why would I be bothered with some pesky human emotion as mediocre as jealousy?” Sukuna scowled at the boy, who stood in his domain.
“How did I get here so fast?” Yuuji blinked, staring dumbfounded at the pile of bones under Sukuna’s throne and the water under his feet.
“Did you even hear what I said you idiot?” Sukuna growled.
“Yes, you big baby. So, you were jealous?” Yuuji smirked, walking up the pile of bones, cringing slightly at the crunching under his feet and promptly seated himself on Sukuna’s lap.
Sukuna’s hands naturally went to rest on Yuuji’s hips as he straddled him on his throne, cuddled up against his chest. He was immensely content in this moment, but decided not to give the teen the satisfaction of seeing him smug.
“Protective.” Sukuna grumbled.
“Jealous.” Yuuji cooed, pushing the neck of the curses kimono aside to reveal the skin of his chest, placing a kiss to it. Sukuna growled quietly, but otherwise stopped speaking, squeezing the boy on his lap.
Yuuji of course found this adorable, because it meant Sukuna cared about him, and even despite all the cruel words and dissing, he had a soft spot for him. It was odd, because he was a horrible being and killed so many people, for fun, yet he had taken a liking to him for some odd reason.
Though Yuuji would be lying if he said he didn’t feel the same for the curse, he had no idea why he was so infatuated with him, but he just chalked it up to being comfy and giving great hugs.
“He should know his place…” Sukuna grumbled out, eyes looking out over his domain with a false bored expression. Yuuji smiled, shaking his head fondly, lifting his head to gently rub his nose against the column of Sukuna’s throat.
Sukuna hummed in appreciation, eyes closing and letting his head fall back to rest against the cool concrete of his throne. Yuuji sat up, placing his hands on the curses broad shoulders to allow himself to be able to get into a comfortable position. Once he was settled, he lifted one hand and with the gentlest of touches, like the kiss of butterfly wings, traced along the marks on the kings face.
“You having fun?” Sukuna snorted, keeping his eyes closed as he preened under the gentle ministrations of his sweet Yuuji.
“Yes, besides, I don’t think you’re complaining.” Yuuji giggled. Sukuna hummed, but otherwise said nothing, feeling himself grow drowsy..
Once he was done tracing the marks on the curses face, he scooted back a bit on Sukuna’s lap, and pushed the kimono off those broad shoulders.
“If you wanted to get me naked you could have just asked.” Sukuna smirked, peeking an eye open to look at the boy who sat so prettily on his lap.
“I’m not trying to do you!” Yuuji scoffed, blushing bright and hot under that half lidded gaze. Shyly he resumed his tracing to the markings on the curses fit torso, smiling soft at the subtle twitches as he reached more sensitive areas.
“You’re going to put me to sleep..” Sukuna mumbled sleepily.
“Would that be such a bad thing?” The teen whispered softly, leaning in to press a chaste kiss to Sukuna’s willing and pliant mouth. The action pulled a moan from him, kissing back lazily, fingers massaging the muscles of the teens hips.
These were some of Yuuji’s favorite moments, seeing Sukuna so at ease and soft, it was rare he got to see him like this. The curse had a hard time relaxing, but Yuuji had always managed to make it happen, allowing gentle touches to lull him into a wonderfully docile state.
“If I fall asleep you’ll leave…” Sukuna protested, voice dipping an octave lower as sleep held him in its clutches.
“Sukuna…” Yuuji said softly, moving his hand from his torso, and into Sukuna’s matching peachy locks. The curse moaned in appreciation, sighing out pleasantly, shivering just slightly at the wonderful feeling of Yuuji’s blunt nails scratching over his scalp.
“You don’t have to worry about me leaving…I’m not leaving YOU, I’m just leaving the domain baby…you can bring me back when you wake up.” The teen said quietly, continuing to run his fingers through astonishingly soft hair.
“I-I’ll wake up the second you leave…” Sukuna fought the sleep that threatened to claim him, and kick his dearest love Yuuji out of his domain. Sukuna was often awake, and usually pulled Yuuji into his domain, but if he fell asleep his control slipped and Yuuji would be returned back to the normal world.
They’d figured this out the few times Yuuji managed to coax him to sleep, but the second his presence disappeared Sukuna woke up, missing the comforting weight that had been draped over him moments before.
“So don’t fall asleep.” Yuuji teased, giggling softly as he stole another sleepy kiss from the pliant curse. Sukuna kissed back easily, melting into the humans touch and welcoming the affection.
“Quit touching me like that..” Sukuna sighed when he pulled away, jerking his head slightly in a poor attempt to get Yuuji’s fingers out of his hair.
“Fine.” Yuuji smiled, shaking his head fondly as he stopped playing with Sukuna’s hair, settling back against his chest, which was still exposed from his previous touching. He had no complaints though, because Sukuna was warm, and Yuuji was happy to leach the heat from his body.
“This may be even worse..” Sukuna’s husky voice vibrated through his chest, sighing as the comforting weight of his lovely host lulled him to sleep like a weighted blanket.
Damn Yuuji was his weakness in every possible way…
“Shall I leave?” Yuuji made to sit up, smirk firmly planted on his lips.
“NO!” Sukuna shouted, suddenly wide awake as he firmly pressed the teen back against his body. Yuuji’s laugh rang through the domain, light and cheery, full of bright wonderful gross human happiness.
“I’ll stay, I never leave you willingly anyway.” Yuuji said softly, tracing random shapes over the taut pec that his cheek rested against.
“I know baby…I know..” Sukuna cooed, rubbing his hand over Yuuji’s back, savoring this moment. He’d keep him here forever with him if he could, but he knew the boy had a life and friends that he liked.
“I love you Kuna..” Yuuji mumbled, a blush crawling up his neck.
“I love you too, brat.” Sukuna spoke softly, voice tender and kind, eyes trained on the boy in his lap.
“If this wasn’t such a nice moment I’d punch you.”
Sukuna laughed at that, the boy knew he’d never win a fight against him, but it was still quite funny. Yuuji of course had been able to land a few punches here and there when they’d fought, but ultimately Sukuna always came out on top.
“You’re cute when you’re grumpy.” Sukuna chuckled, ruffling Yuuji’s soft peachy hair. He got no verbal response only a grumble in response and the boy trying to move impossibly closer.
They sat there in silence for a few minutes, and Sukuna would have thought Yuuji had fallen asleep, if it weren’t for him sitting up to look at him. The boy said nothing, only stared at him, causing Sukuna to raise a perfect eyebrow in silent question.
“And you’re cute when you’re jealous.” Yuuji smirked.
“I don’t get jealous.” Sukuna growled, baring his teeth at his smug host.
“Clearly.” The teen rolled his eyes fondly. “So what would you call it?”
“Protective.” Sukuna said stoically.
“No I think the term is jealous.”
“If you don’t shut up I’m going to send you away.” Sukuna glowered, causing Yuuji to laugh at him.
“You could never. You like me too much.” Yuuji smiled, cuddling up against the curse again.
“Wrong.”
“Wrong?” Yuuji sat back up to look at Sukuna concerned.
“I love you too much.” Sukuna spoke softly, gently cupping the baby soft cheek of his sweet host and leaned in to rub their noses together. Yuuji blushed, smiling fondly at the curse and tilted his head to kiss the king.
It was everything they needed, calm and relaxing, not a lick of tension in the air or in their muscles. Sukuna could definitely get used to this, but he didn’t have to, he already was. Yuuji was the only human he’d ever need or tolerate, and he was damn well going to keep it that way.
"Jealous."
"I'm going to kill you."
"I love you too." Yuuji giggled, causing Sukuna to roll his eyes fondly.
Yeah this was everything he wanted, and more.
