Sukuna and Toji start interacting with each other because their daughters Yuuji and Megumi are besties and they spend all their time together. after a while they become friend too and all they talk about is their daughters and advice on how to deal with them and when Sukuna feels Yuuji has become more rebellious lately he rushes to Toji to get his advice on the subject (but i think they're terrible parents i don't think either of them would be a good role model to learn from 😭 maybe advice on dealing in bed with them would be helpful....maybe there will be...group sex sessions) Yuuji is surprised when Sukuna spends time with someone other than Uraume but she's not complain

AU where college freshman!Yuuji was invited to a house party that starts at midnight, and he wants to go REALLY badly with his friends, but his Strict Stepdad!Sukuna has him on a hard 10:00 pm curfew 😔 So, later that day, frustrated with his stepdad’s TOTALLY unreasonable rules and feeling a bit naughty, Yuuji strips naked and goes into Sukuna’s office, where he’s doing some work 😏 When Sukuna looks at him, Yuuji smiles at him sweetly, saunters over, and unzips Sukuna’s pants to take out his massive cock. Then, after climbing onto Sukuna’s lap, Yuuji begins gliding Sukuna’s cock along his pink pussy lips. “Dad, can you pleeeeaaaaaase get rid of my curfew?” Yuuji croons, batting his eyelashes. “It’d make me so happy if you did~” But in Yuuji’s little attempt to be oh-so clever, he forgot one important thing: Sukuna is NOT some Pushover Papa 😤 He’s a strict stepdad who takes his duty to keep Yuuji safe and to discipline him VERY seriously

And true to form, Sukuna, annoyed by the sheer audacity of Yuuji trying to seduce him into changing his rules, does NOT fall for Yuuji’s obvious little scheme. Instead, Sukuna pinches Yuuji’s clit hard, making him squeal, before he spins Yuuji around so that he’s facing the floor and his midsection is over Sukuna’s lap, and gives him a firm, hard spanking, lecturing him all the while about what a Bad Boy he’s being. Then, when Yuuji’s butt is cherry red and throbbing and his eyes are getting misty, Sukuna sends Yuuji to his room to think about his poor behavior

And almost immediately after Yuuji goes to his room and gingerly sits on the bed, he thinks about the little stunt he just tried to pull, and he gets overwhelmed with guilt and remorse about what a Bad Boy he was being, trying to manipulate his papa like that 🥺 On top of all of that, the soreness of his butt and the memory of how Sukuna’s cock felt slipping across his pussy folds makes him desperately wet and horny 🥺🥺

So when Sukuna checks on him an hour later, he’s greeted to the sight of a sniffling, teary-eyed Yuuji. “I’m sorry, Papa,” Yuuji whimpers, his lower lip wobbling. “I’m sorry for being such a bad boy…” Then, when Sukuna sees Yuuji’s genuine contrition and gives him a stern nod of forgiveness (one that also warns him to be on his best behavior in the future), Yuuji begs Sukuna for cuddles and cock, which Sukuna lovingly provides 🥰

So, in the end, as it always should be, it is a complete and utter victory for Strict Stepdad!Sukuna: 1) Yuuji got punished; 2) Yuuji ended up begging for Sukuna’s cock after trying to manipulate him with sex beforehand; 3) Sukuna got to fuck Yuuji’s delicious little pussy; 4) Yuuji relearned the importance of being a sweet, obedient boy for his Papa; and 5) Yuuji’s curfew ended up remaining the exact same despite Yuuji’s naughty behavior 🎉

Pseudo dadson AU where sugar daddy!Sukuna pays for all of college freshman!Yuuji’s living expenses and tuition in exchange for Yuuji living with him and having sex with him whenever he wants 🥰

Yuuji at first feels bad, because he feels like he’s taking advantage of Sukuna since the odds are SO skewed in his own favor. After all, Sukuna’s an old man (in his fifties), so his sex drive must be almost entirely dead, and Yuuji’s now getting so much in exchange for giving so little, right?

But in reality, Yuuji swiftly discovers that Sukuna has an insatiable sexual appetite, and Sukuna ends up screwing Yuuji multiple times a day until Yuuji passes out, pussy creamed, legs trembling, and drooling in a total cumbrained daze. In fact, Sukuna’s stamina is so much better than Yuuji’s that he has to continue railing him even when Yuuji’s unconscious (consensual somno, I guess)

And Yuuji…… Yuuji’s totally lost. At first, he just saw the sex requirement as a means to an end, but now, after discovering just how impossibly GOOD this dirty old man is making him feel, Yuuji begins to seriously consider dropping out of school and becoming Sukuna’s full-time boywife (something that Sukuna 1000000% supports 😈)

Tbh, it’s almost PAINFUL just how blatant Yuuji’s daddy issues are in canon. I mean, when Wasuke tried telling Yuuji about his mom and dad, Yuuji basically lashed out and said he didn’t want to hear about them in the exact upset, hurting kind of way that only someone with INTENSE daddy issues would have

So Sukuna is a complete FOOL because if he just gave into the all-consuming paternal instincts he had for Yuuji and treated him like his son like he always wanted to, he would’ve never lost in the end, and he would’ve never had any problems. The literal MOMENT Sukuna would’ve began giving Yuuji the firm hand of a stern and stable father figure, Yuuji would’ve gotten totally overwhelmed and would’ve instantly submitted to him in a daze of complete and utter adoring worship ❤️❤️❤️ Like, if Sukuna took Yuuji’s chin in hand to tilt it back and make Yuuji look him in the eye, stating a gruff “Behave, little one,” Yuuji would’ve IMMEDIATELY folded and gotten all weak in the knees. And if Sukuna sat back and pointed at his lap with a stern look, which would make Yuuji shiver as he obeyed and laid himself over Sukuna’s lap, and Sukuna ended up spanking him while lecturing him about how reckless he was being, Yuuji would’ve become even more overwhelmed with how much he adores Sukuna 🥺 (Especially if Sukuna looked older……. Like with some gray streaks in his hair and maybe even a few wrinkles…….. oh, Yuuji would’ve been LOST)

And in this AU where Sukuna isn’t a self-denying idiot, I think that they would’ve had their first time together (where Yuuji gives his virginity to Sukuna) after Sukuna saved Yuuji from Mahito 🥰 Like, when Mahito would’ve tried to kill Yuuji like he does in canon, Sukuna would’ve lost it and slaughtered him in the most mindless, brutal way possible, snarling, “Don’t you dare lay your worthless hands on my son.” And it would’ve driven Yuuji absolutely WILD….. it would’ve been his dream come true………… A father that loves, disciplines, and protects him……….. Yuuji’s heart would’ve soared and his pussy would’ve gotten so wet………. And when they would’ve made love later that night, Sukuna would’ve praised Yuuji as he fucked him so slowly, saying things like “You’re so tight for me, my sweet, precious boy.” And Yuuji would’ve whimpered, looking up at Sukuna all vulnerable and honest, moaning things like “I love you, dad” ❤️❤️❤️

UGH, honestly, the only valid reason to execute Sukuna in canon was the fact that he absolutely fumbled his little boywife

Sukuna is the most famous and dangerous mafia boss in Japan. He meet fem Yuuji by chance in a nightclub, When he ask her if she is new here cuz she looks nervous and shy in the bunny costume She felt comfortable with him and tell him her entire life story almost and she has to work here to collect money for her grandfather's treatment, so this is her first day, Sukuna kindly gives her money and tells her to take care of herself, Yuuji thanks him profusely with cry from happy. by chance throughout the following weeks they meet by chance almost everywhere, a cafe near Yuuji's college, near Yuuji's apartment. She invites him to enter her apartment cuz he is a good man It's impossible for him to be anything other than that, cuz he helped her always. Sukuna enters her apartment for the first time(maybe the first time) it's is a little old and small but it's not a problem this is what Sukuna is thinking, they will get married after a while and she will move to his house.
