Femkuna being gifted shotadori for her harem, she goes through concubines like they’re candy bc she eats them when they bore her or on a whim. No one expects yuji to last long, he’s tiny barely has anything to offer his mistress, until kuna realizes she really enjoys bullying shotadori until he’s crying and begging her to stop.

Shotadori came with an innate rct ability and his crazy level of strength, but kuna likes how she can bring him close to tears with barely a swat to his ass.

So it becomes a game to her to get Yuji to be unable to live-exist without her, to make him addicted to her praise and acknowledgment, to get him to eagerly listen to her even if it’s something that’ll hurt him.

Anyway, I enjoy femkuna fondling shotadori during a big banquet, making him cry as she makes him cum in front of a crowd; Yuji doesn’t like having naked body seen by others who aren’t kuna, he’s shy.

Yuji having a mother complex, and everyone side eyes him bc of all the milfs he his pick of, it’s his bitch of a mom that has Yuji acting like a love sick puppy. Literally, Yuji is catnip for milfs, he always seems to attract them out of all the people he saves, something about knowing exactly how to handle and please an older woman. Sorcerers aren’t bothered by the incest, what everyone had beef with is how much of a bitch sukuna is, she only had Yuji to get clan heads off of her back about having a heir and the moment she popped him
Out, she got even worse. What everyone doesn’t know is that kuna is actually super possessive about her son and got sick of people trying to take him away from her emotionally; she groomed him to always need her and seek her out. The first time someone brought up a marriage contract for Yuji she caused a bloodbath.

Alpha Yuji who is upset with his twin alpha sukuna who keeps sleep around and having close calls with omegas. It’s one thing to be dating them, but if he’s being reckless and almost getting accidentally mated every time, Yuji has to do something as the responsible son.

Cue Yuji tying him up, drugging him and forcing him to fuck and knot a sex toy over and over as punishment for being horny bastard of an alpha.

It drives sukuna wild to see yuji covered in his cum, marking his territory, and awakens the sleeping brocon in him.

Afterwards he starts acting possessive and territorial over Yuji, becoming even worse when he hangs out with non-betas. So he manipulates Yuji into giving him handjobs regularly, he gets off on his knotting in Yuji’s hands, and wants Yuji to sit on his face but can’t man up to beg for it.

Mer sukuna who is egg bound bc he refuses to let the eggs drop bc they are proof that he has feelings for Yuji, and if feelings are getting involved he wants Yuji to drop eggs first. Being egg bound makes sukuna extra moody and aggressive, on top of him not seeing any sign of Yuji making eggs like he is (their bodies only make eggs when the love hormones are present). The thing is Yuji has also been dropping eggs like crazy but has been hiding them trying to baby trap sukuna, or at least getting a few kids that’ll soften the blow of sukuna not being clear about become life partners (Yuji is dumb but sukuna is also emotionally stupid).
