SUKUNA AND YUUJI ARE BROTHERS

summary: Yuuji finds himself sick, and it gives him a perfect opportunity to spend time with his older brother.

wc: 1.8k

a/n: its back friends. all i think about is them.

Yuuji lets out a mucus-filled cough and Sukuna cringes. The toddler turns to him and sniffles with a frown on his face. The elder, in return, rolls his eyes but readjusts the cool rag on his brother's forehead. "Don't look at me like that. Whose fault is this? If you do stupid things, you have to pay the consequences, little pest."

The boy doesn't move; instead, he just stubbornly shakes his head. "W-Wanted to play!"

"In the rain? Without any warm clothes? You truly are an idiot," Sukuna scolds, grabbing Yuuji's water bottle from the nightstand and forcing it into the little boy's mouth.

Yuuji developed a fever this morning after sneaking out into the backyard last night to play in the rain puddles. Now he was stuck in bed, which was hard for the toddler who was always on the go and harder for Sukuna, who has to pretend that he isn't worried sick.

You walk into the boy's room, and Yuuji immediately looks towards you. He tears the sippy cup from his mouth and lets out a high-pitched whine, already beginning to reach his arms toward you. He knows youll coddle him, unlike his brother, and the exhausted boy was craving attention. When you make it over the bed, he reaches his hands upward to you and pleads, "Up! Up!"

You frown at the boy, already reaching down to scoop him up, but Sukuna quickly intervenes, gently slapping your hand away. "No. He might get you sick too. Brat, you stay in bed."

The toddler opens his mouth to protest, but another cough cuts him off. Then, with watery eyes, he turns to Sukuna and nods. "Yes, b-brother."

You coo at the boy, using your palm to cup his warm cheek and thumb at the soft skin. Yuuji rests his entire head on the touch, and you frown. "Poor baby," You sigh, and Yuuji, ever the one to love being doted on, nods pitifully, adding an extra sniffle for effect. Sukuna almost rolls his eyes at the action.

"Why don't you coddle me like that when I am sick?" Sukuna complains before reaching over and pulling the blanket higher up Yuuji's chest. The boy mumbles out a thank you, but the elder ignores him.

"You whine too much, act like you are dying. Yuuji isn't being dramatic, huh Yuuji?" The boy nods, gripping your arm and rubbing his face into your hand.

"No," he mumbles, "Not being dramatic!" He lets out a loud whine, and Sukuna already knows what's coming. "Feel so bad. Hurts!"

The boy seems to curl around your arm, and Sukuna sighs. "Yeah. Not dramatic at all." The kid sounds exactly like Sukuna when he is sick. Just minutes before, he proclaimed to Sukuna that he wanted to play again, even if he was still immensely ill. He just wanted attention, and it was obvious to everyone but you.

"I know, I know. I'm sorry, Yuuji. I brought you some medicine that will make you feel better." The boy's face drops at the word, and he hesitantly lets go of your arm. Sukuna barks a laugh at Yuuji's now twisted face.

The toddler shakes his head gently, too tired to show his real disapproval. "N-No! No medicine!" It always tasted horrible to the toddler, and he knows that if he whines enough, he may be able to get his way.

Sukuna sighs, holding out his hand to you, and you drop the bottle into it. Then, he pours a copious amount of the pink strawberry-flavored liquid, made specifically for children, into the small measuring cup.

Yuuji starts to scoot backward on the bed, trying to create some distance between the two. The elder does not let him go far – he grabs Yuuji's hand and places the small cup into it. "Now drink it, or I'm forcing it down your throat."

The boy gulps, glancing at you, who gives him an encouraging nod. Then he places it to his lips but pauses. "Go on," Sukuna demands.

"I want a treat after!"

Sukunas barks a malicious laugh, and you raise your eyebrows at the boy. You have never heard him try to negotiate before. "Bullshit. Your "treat" is not to be stuck in bed, weakling."

You narrow your eyes at him when you hear the curse word, but Sukuna shrugs it off. Yuuji, on the other hand, eyes widen, and he shakes his head. "Bad word!" He then turns to you in confirmation, pointing at his brother. "He said a bad word!"

You nod your head at him, trying to hide a smile. You were glad that your lessons of not saying curse words stuck with the boy, even with his brother's foul mouth. "Yes, he did. Sukuna, now you definitely owe him a treat afterward."

Sukuna glares at you, but you are used to it, so you instead just flash him a grin. You have told him a multitude of times how you feel about him saying curse words in front of the kid. You didn't want him to grow up so similarly to Sukuna; as much as you love the man, his dirty mouth is not something you hope Yuuji will inherit.

Sukuna turns his attention back to his brother. "You little–"

"Please, Kuna?" Yuuji pleads, letting out another cough that makes him nervous. He rubs at his temple.

"Fine. Whatever. Just drink it, you manipulative brat." Yuujis eyes lighten up, and he brings the artificially smelling liquid to his mouth, cringing but drinking the entire thing. When he pulls away, his face is contorted in disgust, and he looks toward you. You run your fingers through his hair and praise the small boy, grabbing the small cup from his hands.

Sukuna curtly nods his head. "Good. Well, sorry to burst your bubble, brat, but we are out of chocolate. No treat for you," He fake pouts at the boy, but Yuuji, in turn, just shakes his head with a small smile.

"Not what I want."

Sukuna raises his eyebrow, thinking for a second, before sighing. "We are out of popsicles too."

"Not that either!" Yuuji shakes his head with this one, and you cock your head to the side in confusion.

Sukuna borderline growls at the boy. "We are not watching Human Earthworm 2. Last time you nearly pissed yourself from how afraid you were." You laugh at the memory, remembering how much Yuuji pleaded to watch it for days, only to have it be turned off twenty minutes into the movie. The poor boy would make Sukuna walk him to the bathroom at night because he was so afraid of being alone in the dark.

Yuuji pouts at him, and another small cough it let out. You grab him some more water, and the boy mumbles a thank you before turning back to his brother. "I wasn't scared! And no, not that either!"

Sukuna pinches the bridge of his nose, trying not to lose his temper. "What do you want then?"

The smile on Yuuji's face returns, even with the pinkened cheeks and the little bits of sweat on his temples. "Want Kuna to cuddle me!"

Your eyes widen, and you can't stop the laugh that leaves your mouth. Sukuna, on the other hand, goes silent for a long moment. "Not happening. Pick something else."

Yuuji whines out, shaking his head stubbornly. "Nooooo. You said I get a treat!"

"You are going to get me sick."

The boy sniffles at him, shaking his head. "Th-Thought brother was the strongest…"

This makes you grin, knowing your lover's ego well. And just like you thought, Sukuna lets out a dramatically large sigh. "Fucking–Fine. Whatever. Scoot over." You and Yuuji both let the curse word slide, being shocked at him actually agreeing.

Yuuji slides over, and Sukuna forces his way under the blankets beside the boy. You sit and watch as Yuuji basically scampers up Sukuna's chest until his head is placed in the elder's neck and his entire body is on top of the man. "Okay, really?" Sukuna grumbles, and you chuckle at him. "Are you some sort of spider monkey now?"

The boy hums in agreement, pressing himself impossibly closer to his brother. You take this time to stand up from the bed, having no room to fit you both. Sukuna watches you begin to leave and frowns at you. "Where are you going?"

This was a perfect time to give them some bonding time. So you shrug, "I'll be right back."

"You better be," Sukuna grumbles and Yuuji coincidentally sneezes into his neck. The man's whole body jerks, and he cringes. "Hey! None of that, that's disgusting!"

Yuuji whimpers, wrapping his arms tighter around his brother as if he was afraid to leave. Then he whispers an apology, and Sukuna rolls his eyes again.

You grab the door to the handle and step outside. "Well, have fun you two. Yuuji, feel better!"

Yuujis cranes his neck to look at you and waves back to you with a small smile, content in his position. Sukuna, on the other hand, glares at you. "Dont you dare leave me here with this brat."

You huff a laugh, ignoring him and already planning what movie you will watch by yourself. "Love you!"

"Hey!" He yells when you shut the door on him.

And, of course, luck is not always on Sukuna's side. When you come to check on them two hours later, you find them both passed out – Yuuji practically smothers Sukuna with his tiny body, drooling on the elder's face. You leave them like that, not thinking much of it.

But three days go by, and somehow Sukuna finds himself stuck in bed with a fever. He never dared to mention that Yuuji probably got him sick, his pride getting the better of him.

You and the kid walk into your shared bedroom, Yuuji with a massive smile, finally feeling better, and you with a content grin. Sukuna slowly peers over to the door and groans out loud and dramatic.

"Dont worry, Kuna! Dr. Yuuji is here to take care of you!" He cheers, grabbing his toy stethoscope and shuffling over to the bed. He manages to climb onto the bed with his brother without much trouble, and you follow him, sitting on the bed next to your lover. Like you did with Yuuji, you ran your fingers through his hair, trying to comfort him.

Sukuna peers at you, eyes slightly lighting up and a familiar grin pulling at his face. You already know something inappropriate is about to leave his mouth.

"I would feel so much better if you were in a nurse costume right now." But before you could try to reply, Yuuji shuts him up by shoving a toy thermometer into his mouth.
