Chapter Text
Sukuna had finally been trapped in the brat’s body for a long few days after his humiliating fight against Satoru Gojo. For the most part, he didn’t care what the brat was up to. The only thing that was even a slight change was the addition of yet another brat to Gojo’s group of insanity. This new brat was a girl and a feisty one from what Sukuna had gathered. Despite how she seemed to act towards his vessel, she appeared to match his stupidity and weakness in Jujutsu. This of course would earn her the name “Retarded Brat”, which Sukuna gladly declared was much more memorable and creative than “Nobara” as the brat had called her. But now as night crept on Jujutsu Tech, Sukuna decided that it was high time for pestering the brat before he retired to sleep, leaving Sukuna with no entertainment. With any luck for Sukuna of course, the Emo Brat would be in the room as well and he would be able to fervently insult his mother. Even as far back as the Heian Era, it was amusing to insult one’s mother, something Sukuna had taken care of by running away when he was only 8.
“Brat! What idiocy will you subject the world to tonight?!” Sukuna yelled loudly as he finally manifested a mouth and eye on the brat’s cheek. Using his eye to quickly look around the room, he noticed that not only was the brat not in the sleeping chambers assigned to him by Gojo, but that the Retarded Brat was sitting on the bed in front of them, her mouth seeming open in awe.
“What’s this brat?! Defying the rules to murder your enemy in their sleep! A plan of dishonor that Ii have clearly interrupted!”
“W-Wait! Sukuna? Why are you choosing NOW to show up!” Yuji took a nervous step backward as he watched Nobara analyze the situation and her face relax a slight bit from the stunned look of before.
“My intentions won’t be revealed to an idiotic brat like you. However it appears you were clearly intending to murder this brat in her sleep instead of in a fight of Jujutsu!”
“Sukuna, I’m not fighting or planning on fighting Nobara! I was just-” Yuji’s voice is cut off by a cruel laugh from Sukuna, as his face shifts to the back of Yuji’s hand.
“Then what other reason do you need to visit the private room of this brat? The only other reason would be sex.” Sukuna’s tone is plain and blunt to a point where Nobara begins to consider what he was saying. As Yuji tried to stutter out an explanation, Sukuna kept interrupting him with further accusations.
“So it is clear to all that you intend to have sex with this brat who clearly hates your very existence?!”
“Sukuna, I’m-That’s not… Nobara doesn’t hate my entire existence-”
“I wouldn’t normally agree with someone so weak, but the Nobara brat is clearly right to hate you.”
“Sukuna! I-I… I’m not in here for any sex, or to kill Nobara, and definitely not anything lik-” Yuji is cut off again, this time not by Sukuna’s flaming accusations, but rather by Nobara standing up and speaking in her usual confident tone that quickly silenced Yuji.
“Yuji Itadori, that curse has a great idea!” She held her head proud as she looked over at Yuji, who stood staring at Nobara suddenly dumbfounded.
“W-What do you mean a great idea?”
“She means the duel you must fight to prove your strength as a sorcerer. A test of power, strength, and intelligence, something I possess all three of-” Sukuna is cut off suddenly as Nobara raises her voice as if to drown him out.
“What I mean Yuji, is for us to have sex! Clearly you are physically strong and even I can notice a good body!” She grinned and walked over to Yuji, her mere presence intimidating him as Sukuna retreated to spew hatred straight to Yuji’s mind.
“Ha! Such a brat getting pushed around and scared like this. You’re such a pathetic excuse of a sorcerer.” Yuji ignored Sukuna’s vile remarks, quite used to the constant insults by now. But as he looked down at Nobara, he felt a strange push to try something else than just let her walk all over him.
“Hey! If you want it, then who am I to deny this to you!” In an imitation of Sukuna, Yuji quickly pulled his shirt off his chest, finally showing off his natural physique by himself, not with Sukuna doing it for him, in a way that was much more wasteful. As Yuji lowered his arms and grinned at the sight of Nobara blushing at him, he smiled a soft smile and spoke in a much more careful voice than before.
“O-of course… I stand by what I said, but we can be slow and careful and make sure you don’t hurt…” Yuji’s voice trailed off in a word salad, before he decided to just grin his signature goofy grin. This worked in his favor, as Nobara leaned closer and pressed her hands up against his chest, running her fingers along the lines of his body.
“T-thank you for considering me Yuji… that's nice…:” Nobara looked sheepishly at Yuji as he realized her face was a deep red. Not failing to see his chance, Yuji leaned down and kissed Nobara on the lips, the warmth of her own melting away as her hands moved up to hold his shoulders, while Yuji’s arms awkwardly wrapped around her back. The kiss only lasted a few seconds, but for all three parties, both involved and the one forced to witness it, It felt like forever.
“Disgusting. You’re pathetic and can’t even do this shit right.” Yuji barely registered Sukuna’s words, his mind hazy from kissing Nobara before he felt like he was falling. In a sudden moment, Nobara was pushed to her bed and her pajama top sliced clean open down the center. A look of triumph and glee was on Sukuna’s face if but for a second before Yuji took back control, just for his face to fall right between Nobara’s breasts.
“Now that is entertaining to watch..” Sukuna kept this thought private as the events played out before him. He had expected to be forced away from control of his body, especially when having to use Dismantle just enough to not harm Nobara. Yet as Yuji sat up and rubbed the back of his head, Sukuna was further entertained as Nobara grabbed his head and pulled him down on her body again.
“I haven’t the slightest idea of how you did that Itadori, but if you’re going to ruin my pajama’s like that, you had fucking BETTER make it up to me!” Sukuna laughed as Nobara’s voice echoed through inside his mind. This was getting to be almost as fun as killing people.
“W-Well how? I mean, it wasn’t even me, it was Sukuna!” Yuji’s protests fell on Nobara’s deaf ears as she stopped and glared up at him with fake contempt in her eyes.
“I don’t care if “Sukuna” did it, you’re gonna repay me by using that idiotic mouth of yours on my breasts! It will also shut you up before you say anything stuuuuuuuu-” Nobara’s voice trailed into a high pitched moan as Yuji placed his mouth on her left breast, his tongue flicking across her nipple. His other hand found its way up to Nobara’s right breast and began to work on that one. Sukuna never bothered to do any of this in the Heian Era, but even he could tell from the frantic moans of Nobara and how her body writhed beneath Yuji’s that she clearly enjoyed it. Even Yuji himself was rock hard, leaving Sukuna to be ever so slightly amazed that such a worthless pathetic brat could be so well equipped.
“O-Oh… Oh fuck Itadori…” Nobara’s body writhed, her hips bucking up and her hands trying to reach for her pussy, to relieve the quickly growing tension between her legs. Every time she dared to open her eyes however, or move her hand under Yuji, he would somehow sense it and do something to stop her. Each pinch, suckle, and bite was met with more loud moans from Nobara and only drove her closer to orgasm.
“Y-Yuji… I-I am…” Nobara’s breathing was heavy, riddled with moans as Yuji never failed to stop. Knowing from his own erection and her words that Nobara was close, he finally let go of her left breast and placed his mouth on the right. With his left arm now free to move, he thrust it downwards, feeling the outline of Nobara’s pussy through her wet pants. With one final moan however, Nobara bucked her hips upwards right into Yuji’s hand, allowing him to feel as she soaked her pajama’s pants through. The sudden combination of Nobara’s orgasm and simply suckling fervently on her nipple forced Yuji over the edge as well as he busted a fat load inside his boxers. Sukuna watched as Yuji sat up and looked down at Nobara, grinning pleasantly as she stared up at him.
“Damn it Itadori…” Her tone was light and teasing, yet still held the sharp edge of before. “Guess you just had to ruin the rest of these pajamas huh?”
“I-I… I…” Yuji struggled for words before the clarity hit his mind and he realized that it was just 9:34 PM. Yujo knew he wouldn’t last long being so young, but only a minute really was embarrassing. So much so that Sukuna felt the perfect place to taunt and further ridicule Yuji.
“I could go for hours on end, so much so that even the women were tired out long before I was.”
“Shut up Sukuna!” Yuji shouted in the air before looking back at Nobara, who just lay in her bed panting. “I-I uh… need to go. Megumi is going to be in our dorm at 10:00 and I need to get back…” Yuji’s voice trailed off as he quickly ran out the door, leaving Nobara alone, but satisfied enough to not care.
