Ik ik sukuna is not in haikyuu but I really had this thought so I decided to write it down for u guys, btw no spoiling I haven't finish jjk cuz of my tests now enjoy!

So yuuji asked u out, u said yes cuz after all he's such a cute and nice guy, when the date day came he took u to a cafe and after that u guys went for a small walk, it went completely good he talked to u about everything and told u how annoying sukuna is ,then since it was too hot outside he asked u if u want to go to his place and u said okay and u knew it's gonna go fine cuz its yuuji after all, after u arrived u told him that ur a pretty skilled cook and u wanna make a fast cake for him so u started working like normal, u were humming a song when u heard : "what a beautiful singing I'm hearing rn~" u got surprised not cuz of the sudden compliment no it was because it wasn't yuuji's voice, u were just about to turn around when u found him behind u already , ur eyes widened, u told urself :' so this is ryomen sukuna?' he looked at u while he smirked, he said : " oh then that damn brat has a good taste huh? "u pushed him saying :" w-where is yuuji? Give him back! " and u took ur cursed sword, he said :" ohoho? U have guts don't ya? Trying to pick a fight with the king of curses" u replied :" just answer my question asshole! Where is yuuji!!!!! " he said :" don't tell me... U like him? " u replied with a tiny blush in ur cheeks :"that's none of ur business and for the third time give him back! " he replied :" no~" u said :" but I thought he had control over u??? "he replied :" well now he doesn't , I found a way, he's knocked out now "u replied :" h-huh?" he said :" well don't make such face little lamb ~ am I not enough for u? " he said that while getting close to ur face u replied :"get the fuck away from me! " he replied :" or else what? ~ u have no chance against me u know that, because ur weak " then he took ur sword and threw it away, u got really mad of him saying that u r weak :" I'm not weak! And who TF r u so u can say that I'm weak huh?! U don't even know me and u have never seen me fight or train don't know how much i train plus it's none of ur business u fucki-" he shut u up with a kiss, ur eyes widened, for a curse, he damn was a really good kisser but u had to push him away so u kept pushing him and hitting but he didn't move for a single second instead of that he held u closer by your waist, after he broke the kiss u said :" WHAT WAS THAT FOR HUH?! " he said :" u know its been a really long while I haven't been attracted to a women ~ " u replied :" do u think I fucking care?! U just took my first kiss without my approval! " he said :"oh so this actually is ur first kiss!, how fun ~" u said :" now get off me and get yuuji back !" he looked at u with a serious look on his face and said :" don't order me around lamb know ur place " u looked at him terrified thinking that he might kill u right now ,then he kissed u again holding u closer than before, u moaned in his mouth cuz he was crushing ur body, some tears fell and when he finally broke the kiss he looked at u, breathing heavily, crying he said :" what's wrong u didn't like it this much? " u replied :" u-u probably b-broke my bones, i-it hurts "he said :" is that so? Well it's kinda ur fault after all, ur the one who kept being a brat " u said looking up at him with anger and tears in ur eyes :" I hate you "he was surprised by that and said :" hate? What a strong word to use "he then touched ur face and wiped ur tears and then said :" well but I don't so u have no choice but be my prey ~" he then held u closer and whispered :" ur so cute when u cry u know that? " he then picked u up while u were hitting his back he said :" u know that that's useless u cant get free from my grip little lamb " he then took u to the bed then threw u on it the next thing u saw is him taking off his shirt and his abs showed up and what made him hotter are the things that looks like tattoos the he said :" take off ur clothes " u didn't answer " I said take off ur clothes " u replied :" yeah like I'll do that " he then said :" u left me no choice then I have to take them off by myself "u backed down a bit then he started getting closer to u and when he reached u he whispered in ur ear :" ur the first women in decades that turns me on~" u looked down and u saw that he was actually hard then he said :" come on baby u know u have no other way, if u accept gently I'll go gently or its the other way around, it's ur choice, oh and of u choose the first option you'll get that brat back safe " , u had no choice with yuuji being on the line, u didn't want him to get hurt, so u turned ur head right and blushed deeply he understood what u chose he said :" good then~" he started kissing u deeply and this time u melted down with it then he started kissing ur neck and then he bit it and u moaned from the slight pain after that he licked where he bit u then he took of ur shirt exposing ur bra, he said :" what a nice color ur wearing ~" u blushed even harder then he saw how fast u r breathing he laughed a bit and said :" relax a bit ur heart is goona come off like that " he then reached ur back and started unpluging ur bra u closed ur eyes cuz u didn't want to see his face and when he took it off he kept looking at your boobs and then held them and u flinched a bit, his hands were warm then he started kissing and biting u were dying from the embarrassment while he kept kissing and he kept going down on ur waist doing the same thing then he said:" hey I just realized smth ~ since that was ur first kiss then this is ur first time too?~" you didn't reply he said :"u better answer " u replied :" y-yes" he said :" I knew it! ~ well then u should be glad that ur first time is gonna be taken by me " then he stood up and took off his pants and his underwear and u were shocked cuz that shit was like 10or 11 inches u said without thinking :" I didn't know yuuji was packing?! "then u realized what u just said then he replied :" well ur kinda wrong about that, it's actually me who's packing when I get in a container some organs changes from his to mine like my dick "and then he got close and kissed u and said :"and my mouth~"u blushed so hard and he said :" now suck it " u said :"what? "he repeated :" I said suck it " u replied :" b-but Idk how to? " he said :"just put it in ur mouth you'll figure it out " u hesitated for a bit and then got down and tried to put it in ur mouth but then he thrusted his dick in ur mouth and u couldn't even breath he said :" watch ur teeth lamb" then he pulled u up and thrusted again and he kept doing that till he came in ur mouth u coughed with the cum in ur mouth then u looked at him and he said :" swallow it all "u looked at him surprised then he said :" I said swallow it " and then u did after that u sat tryna catch ur breath then u said :" now give yuuji back " he laughed and said :" who said I was finished?" he pushed u down the bed and got on top of u after taking ur panties off he looked at it and said :" u r wanting that brat back while u r this wet for me? ~ , well well since this is ur first time I'll have some mercy and go gentle, maby " then he thrusted all of his dick in, u moaned so loud I think the people in Mozambique heard u he said :" shhhh u don't want other people to hear us don't u? ~" he thrusted again and said :" fuck ur-ur so tight~" u said while moaning :" s-stop-p it h-hurts!"he replied :"ohoho?~look who's talking, the person who was soaking wet earlier " ,even tho he told u to shut it but u couldn't so he kissed u and said :" this should shut u up " u kept moaning in his mouth while he kept thrusting in u when he broke the kiss u said :" s-stop p-please s-stop , i-i beg-g u s-sukuna! " he replied :" just for your information, that begging of yours just turned me on more ~" then he thrusted faster until he came in the same time u fainted when he saw that he said :" u-uh? She fainted " he smiled and said :" what a sensitive girl ~" then he slept next to u hugging u to his chest
