Chapter Text
The next morning, Sukuna is nowhere to be found. Yuuji hesitantly spent some time looking for the curse before deciding it must be gone, which made Him feel much safer as he explored the estate further. While he was still able to hone his physical abilities, his cursed energy was completely useless due to whatever binds Sukuna had placed on him. So, he was pretty bored, and maybe searching for anything that could give him an idea of how to deal with the binds.
It was then that Yuuji came across another daunting-looking room, hopefully not something that would get him into a similar situation as last time. He cracked the door and peeked in, a huge number of books welcoming him. Sensing that it was probably safe to venture further, Yuuji entered the room, shocked by how huge the library was here. Although maybe it did make sense, thinking back on the books that Sukuna had in his bedchambers.
Many of the books were quite discernible to Yuuji, but some of them began to catch his eye. There were massive amounts of books about sorcery in here, covering so many different topics. He was never the scholarly type, preferring to jump into a fight and let his fists guide him, but Yuuji supposed that, since he had the time, he could at least try to gather some info, maybe even some that could help him out.
He began skimming through the books, aiming to find something that seemed like it might have information on seals and curse bindings. After all, his cursed energy was stuck due to whatever the tattoo-like talismans on his body that Sukuna had placed on him.
Eventually, he had grabbed three books, all with kanji that he couldn’t really understand at length due to the amount of time that had probably passed since they were written. Opening the first one, Yuuji was already straining himself and his brain to get through the dense texts. Most of the information was about the history of talismans and seals, nothing that was really going to help him; kind of like how all his math textbooks in school spent half of every chapter going over the history of equations and the ancient men who made them. After a while, he finally came upon something that seemed relevant, courtesy of the illustration on the page.
“The base of all cursed bindings is the fact that they are imbued with cursed energy. This cursed energy must be embedded into the bindings with a clear intention for them to perform their desired function.” Huh, so kind of similar to binding vows?
Yuuji then looked up from the book and closed his eyes in concentration, trying to feel the cursed energy that, while unable to be fully brought out, was still present within him. When trying to bring it up and outwards, it almost felt like there was a block, something preventing his cursed energy from moving any further. He could feel it right up against whatever this block was, but no matter how hard he tried, he couldn’t put it to use. It was also extremely draining; after only a few minutes, Yuuji felt as if he had been out fighting curses all day.
So, with what Yuuji understood, which wasn’t a great start to be honest, the cursed bindings were made through some Sukuna, with the intention to keep his cursed energy at bay. If he could only figure out what exact condition Sukuna had placed, he might be able to finesse it a bit. Now, Yuuji was never the brightest academically, so it wasn’t his fault that he didn’t notice the loud footsteps coming up behind him; he had to use all his brain power for this after all!
“Well, Itadori Yuuji, with his head in a book, who thought we’d see the day?” Sukuna’s baritone voice broke Yuuji from his spell, making him jump up a couple of inches in his seat.
“What? I.. Hey!” Yuuji was on his feet now, poorly attempting to block the books from Sukuna. Obviously, that was useless. The curse simply walked right up to Yuuji, close enough to be touching, and looked over the boy's shoulder.
“Hmm, cursed bindings? Curious about what has your energy in such disarray?” Sukuna bent over with that sly smirk, getting his face close enough to Yuuji’s so that they could feel each other’s breath. “I wouldn’t waste too much energy on it, brat. You need all you can get just to survive.”
Yuuji tried to look away as his face flushed, definitely from embarrassment, of course. “Well, what else am I supposed to do? All I can do when you’re being weird like this is either sit back and take it, or just go in swinging, but I’m not dumb enough to think that’s a good idea.”
Sukuna simply smiled wider, bringing his hand to force Yuuji to look back and return his stare. “Enough of that, you’ll be coming with me now for dinner.”
With that, Sukuna turned and began walking away, and Yuuji hesitated for a moment before cursing himself, following after the curse. He really doesn’t have any other option; it's not like he needs to be choked out again. Eventually, the two were step-in-step. Yuuji kept altering his glance around, looking back and forth between the curse and the halls around them.
“What, has the cat finally caught your tongue? Or are you just enjoying ogling?" Yuuji just glared at the curse in response to that remark, while Sukuna simply continued staring ahead.
“Ugh, no, you’re just-you’re such a weirdo.”
“A weirdo? Surely you can do better than that.”
He didn’t get a chance to respond before Sukuna took a turn, the opposite way from where they usually dine. Rather, they were now on course to Sukuna’s chambers. Yuuji stumbled a bit and started trailing behind, hesitant about what was about to happen.
“What? Afraid you’ll get in trouble again? I’m not going to choke you again, brat,” Sukuna came to a sudden stop, causing Yuuji to run into his back, and Sukuna looked down over his shoulder at him, “Unless you want me to, of course.” And the curse simply turned forward and began walking again.
This time, a cat really must have caught Yuuji’s tongue, because he was too stunned to respond to whatever the hell that meant, so he just kept following along.
They made it to Sukuna’s chambers, where there was a shoji door that opened out to reveal a veranda. The sun was setting, and, seeing as it was late December, there was a chill in the room. True to his word, there was food sitting on the elegant chabudai, but Sukuna went to sit out on the veranda, beckoning Yuuji over with his hand, who simply followed orders.
Already, by the time Yuuji made it over, Sukuna had a pipe lit, taking a deep hit before turning to look up at Yuuji, and exhaling the smoke as he made eye contact with the boy.
“Come on, boy, sit.” And sit Yuuji did, with an over-dramatic sigh.
Sukuna took another inhale from his pipe, this time blowing it directly into Yuuji’s face, causing the boy to try and fan it away while coughing.
“Dude, what are you doing? What even is that? I didn’t take you as the type to enjoy tobacco.”
“Tobacco?” Sukuna had a mocking tilt in his voice, looking over with fake shock in his face. “It amuses me that you would think I’d indulge in your modern vices when there are much more pleasant options.” He took another hit, again blowing it into Yuuji’s face.
At this point, Yuuji’s head was starting to feel fuzzy; in fact, everything started to feel fuzzy, and not in a bad way. He may have even started to lean further into Sukuna, looking for warmth against the winter chill. Sukuna took yet another puff, blowing it into the boy’s face. Yuuji didn’t shy away from it this time.
“Hey, what is that?” At this point, Yuuji was leaning up against Sukuna, almost nuzzling into him, talking as if this was a new conversation. “I feel kinda weird.”
“Opium. You should be feeling real good, kid.” Instead of simply blowing his next puff onto Yuuji’s face, Sukuna grabbed him instead, bringing his lips to Yuuji’s, blowing the smoke into his mouth as they kissed. Yuuji only processed what happened seconds after Sukuna pulled away, and took even longer to realize that he definitely kissed back. He didn’t dwell on it for long, though; why should he worry about it when he feels so good right now? He didn’t even mind the fact that Sukuna kissed him; right now, even he could admit that Sukuna was right. He was feeling real damn good.
Sukuna put the pipe down, instead using two of his arms to lift Yuuji and place him in his lap, this time facing him. Yuuji just huffed out a little giggle before he put his hands on Sukuna’s shoulders, not even questioning the fact that he was currently straddling him. He moved his hands up and wrapped his hands around Sukuna’s neck before he put his weight forward and stuffed his face in the man’s neck; the feeling of his warmth was like Heaven. In return, Sukuna placed two of his hands on Yuuji’s waist, both of them serving to wrap completely around his middle. Yuuji duly noted that one of Sukuna’s hands was probably bigger than his entire head.
“Feeling good, Yuuji?”
“Mmh, yeah, really good S’kuna.”
Sukuna gripped his waist a little tighter, shifting his head downwards to kiss the boy’s neck. Yuuji would deny it later, but in that moment, he swore he could almost cum just from feeling the curse's breath on his neck.
“Ugh, S’kuna, what the hell are you doing?” He slurred out, as if he wasn’t tilting his head to give the curse more room to work with. The curse just kept kissing his throat, sucking marks all over him.
Instead of giving any sort of answer, Sukuna grabbed Yuuji’s head from behind, angling him so that their lips could meet. Yuuji would never admit how wanton he sounded when he felt Sukuna’s tongue slip into his mouth, licking against his. Sukuna growled when he felt Yuuji kissing back so fervently. He put two of his arms under Yuuji’s thighs, hands on his ass, as he picked him up and carried him back inside. If Yuuji wasn’t high out of his mind, he would’ve noted how gently Sukuna placed him down on the futon right next to the fire, which was lit, same as the last time he was in here. The silk kimono he was wearing drooped down his shoulders, showing off his marked neck, as well as the flush travelling all the way from his ears down to his midsection; Sukuna was eyeing him hungrily.
“You look good enough to eat, brat; it's almost like you were made to reside in the lighting of fire.” Yuuji had half the mind to be embarrassed about the choked sound he made at the compliment, getting even redder.
Sukuna leaned back down over him, and Yuuji met him halfway, the two sloppily making out. The boy couldn’t think of another time that he had been this hard, or this soaked. Everything felt so good to him right now; all he could do was chase after his pleasure. Two of Sukuna’s hands worked at Yuuji’s loosely tied obi, revealing all of him to the heat of the fire, which made him shiver. He sat up a bit, moving his hands to trace under Sukuna’s haori, which had nothing underneath. The curse didn’t stop him; instead, he hummed as he brought his face down to Yuuji’s chest, taking a nipple in his mouth.
That alone made his toes curl, and his hips bucked up on their own, trying to get some friction. Sukuna huffed a laugh around his nipple, and his hands moved to hold the boy's hips down, causing a whine to slip from Yuuji.
“Sukuna, please.” He was all too ready to beg in this moment; he needed more.
“Please, what, Yuuji? Use your words.” Sukuna’s wandering hands moved to grope his ass, spreading him open.
“I don’t- I dunno, touch me S’kuna.” He spread his legs further, far enough so that they were caging Sukuna in.
“I am touching you, brat.” Still, the curse moved a hand to swipe over Yuuji’s cunt. “Who knew you could get so wet, for me nonetheless.”
The single touch alone had Yuuji’s whole body twitching, and his eyes fluttered shut with a moan. He was completely lost, grinding down on Sukuna’s finger, trying to get friction on his cock too. Sukuna was entranced by the view, looking down at Yuuji while panting heavily: his flushed face and closed eyes, his breathy moans and small whines, and the eager grinding of his hips; it was affecting him more than he’d like to admit.
Then, Yuuji opened his eyes and looked up to Sukuna, his eyes glazed over, and Sukuna snapped. He pulled his hands and body away, pulling an annoyed huff from Yuuji, before he grabbed Yuuji’s legs and threw them over his shoulder, his face now level with where the boy wanted him the most. Yuuji threw his head back against the futon, a throaty moan leaving him as he felt Sukuna’s mouth swallow him down, alternating between sucking him off and sliding his tongue inside of him. It was so fucking good, all Yuuji could think and feel about was the heat around him.
“Oh God, fuck, Sukuna-” He was just mumbling nonsense, unable to do anything else. It had been maybe two minutes, three at most, but he was already close. “‘Kuna, I’m gonna cum, please don’t stop.” He was a virgin after all, and a war between sorcerers and curses wasn't exactly prime time to get himself off, so sue him for reaching the edge so quickly.
It was then that Sukuna pulled off of him, licking his lips and placing Yuuji’s legs back down around him. Yuuji groaned, but he was cut off as Sukuna was licking into his mouth again, forcing the boy to taste himself. Yuuji wrapped his arms around Sukuna’s neck, pulling him in closer, and grinding against the curse's cock, which was now open to the air. Sukuna hummed into his mouth in response, grinding back against the boy.
Sukuna went back to marking Yuuji’s neck, and the boy took the chance to look down to get a glimpse of the curse’s body, and his breath caught when he saw the size of Sukuna’s cock. This must’ve caught the curse's attention, because he huffed out a laugh. As if reading the boy's mind, he reached down to stretch him out further, using two fingers to work him open. Yuuji would question his gentle touch when he had half the mind to realize it. Since he had just gotten so close to coming, simply having the fingers inside of him had him on the edge again.
“S’kuna, need more.” He still had his arms wrapped around the curse's neck, flexing around his fingers.
“Impatient brat, you want me inside you that much?” Yuuji just nodded enthusiastically into his neck, whining in desperation. “So spoiled,” and Sukuna pulled his fingers out, instead gripping his cock and lining it up with the boy's opening.
Yuuji saw stars as the curse popped his tip inside slowly, allowing him to adjust for a second before sliding all the way inside, filling him completely. Yuuji’s breathy exhales, and Sukuna’s groans fill the room while neither of them moves. Then, Sukuna perched himself up, hands on either side of Yuuji’s head, looking him in the eyes while he began to pump in and out of the boy.
“Feel that, boy? You must have been made to take me.” Yuuji couldn’t answer with anything but a nod and his moans. If he wasn’t drugged and being fucked within an inch of his life right now, he would totally worry about Uraume hearing how loud he sounded, along with the slapping of their skin.
“Kuna its- so good.” he threw his head back and dug his nails into the man's back, surely leaving marks. “Oh fuck I’m close, so so close, please.” He was nothing but a mumbling mess at this point, drooling and curling his toes at the feeling of his cervix being hit just right. The curse fucked him harder, thrusts getting sloppier as he also got close.
Yuuji couldn’t tell if it had been a minute or an hour before he was coming on Sukuna’s cock, everything was gone except for the pleasure wracking through his entire body.
Once he came back down, he started to squirm from overstimulation as the curse fucked harder and deeper, his stomach fluttering at the sounds he was making, knowing that he was the one who had Sukuna this way.
“Fuck, Yuuji,” and he stilled, pushing as deep as he could into the boy before coming. Yuuji shivered at the feeling of him throbbing inside him.
Both lay there in the afterglow, and Yuuji was on cloud nine, barely even conscious between the sex and the opium. He wasn’t out of the woods yet, though, not a bit.
Sukuna leaned right into his ear, “You think we’re done here, brat?” and all Yuuji could do was giggle as he felt the curse getting hard inside him again. Waking up in horror next to the curse the coming morning was a problem for future him.
