The brother threesome picture gave me thoughts.

Oldest sibling ryo got tired of middle sibling kuna being a huge brat and roped youngest sibling Yuji into punishing him.

Ryo gagging kuna with his fingers, basically throat fucking him so he can’t distract Yuji with his whining and complaining (swearing and cussing them both out).

Yuji is a horny teen, trusts his big brother without question, and craves kuna’s attention, so when ryo told him to fuck kuna, Yuji agreed to it.

Yuji feels absolute love for his brothers and didn’t want to hurt kuna (aka make him resent getting fucked / it’s not rape If he’s gentle), so he prepped kuna nice and slow. He even ate him out so it would be nice and special for him.

Yuji still has a big dick tho, they all do, and even tho ryo is telling him to shove it in, yuji doesn’t want kuna to hate it, so the first thrust so slow, gentle and absolutely dripping with lube.

In the mean time ryo has been taunting kuna, calling him a slutty bitch and whispering how well Yuji behaves for him and how kuna will never be strong like him (very im the top bitch and you’re just a fake loser kind of sibling insult). He even shows off how well Yuji listens to him by telling Yuji to open his mouth so he can spit in it.

This is Yuji’s first time (kuna’s first time bottoming) so it doesn’t take long for him to cum, so he’s just boneless on top of kuna, leaving him plugged with his softening dick.

Kuna didn’t come but he’s close, he hates that he loves being the center of attention, pressed in the middle of his two siblings. He hates how Yuji came in him, still has his dick in him but hasn’t done anything to make him cum.

Ryo then proceeds to tell Yuji to frot against kuna while ryo uses his spit and Yuji’s cum to prep Yuji to get fucked now.

Kuna is flushing, it’s from humiliation at how much he likes yuji’s dick rubbing against his, how he can feel how hard ryo is thrusting into Yuji, and just how hard he his from it all.

He forces Yuji to kiss him, and ryo feeling left out, forces his fingers between their mouths so they’re making out with each other and his fingers.

Kuna comes from Yuji rubbing his dick raw on his, ryo fills Yuji with cum, and after he pulls out, takes a picture of both his baby brothers leaking cum.

Kuna passes out from overstimulation and Yuji is boneless on top of him while ryo is just petting Yuji like a dog and telling him see, kuna needs a heavy hand to be good boy like you.

Ryo is the oldest, clan heir and has been groomed to be perfect. Kuna is the middle child who got spoiled and left off easy since ryo was always there to be the responsible one. Kuna started changing when yuji was born, because yuji was the favourite child of their parents, so they tolerated kuna’s attitude less. But yuji loved his brothers equally, trailed after ryo and kuna like a needy puppy, kuna made him cry when kuna didn’t want to play with him. Of which ryo benefited from because yuji would run to him crying, his crying face is the cutest.

Ryo has been grooming them both to be codependent on him and each other, he absolutely hates everyone else, views the rest of the world as beneath him, and if he has to be clan head who has to deal with garbage people for the rest of his life, he might as well have something to call his own.

Kuna has issues because his whole life has been, why can’t you be perfect like ryo (he does get perfect marks, masters any sport or hobby instant so no one but his older brother can compare), and when Yuji came around, it drove him mad when Yuji wouldn’t look up to just him, he wanted Yuji’s full attention and love.

Yuji just wants love and attention from both his brothers. His fav was when they would cuddle together and have sleepovers when they were young but now all kuna wants to do is fight and bully him and ryo is super busy with heir stuff.

Everything comes to a head when kuna beat up another clan heir for saying shit about in to his face and ryo had to cover it up, and Yuji came home from school to their shouting match where kuna was seconds from attacking ryo.

Afterwards, ryo puts kuna in a cock cage for a week as further punishment, and only lets him out when he begs sweetly, and as incentive, gets Yuji to wash and handle his dick while ryo watches. At the end of that, he fucks kuna while kuna fucks Yuji because he knows kuna likes being sandwiched between them and he likes when Yuji is whining because of him instead of ryo.

Yuji and ryo have been fucking around for while; no penetration other than his fingers so it’s mostly yuji being taught how to suck his dick, and ryo fingering him, as he didn’t want kuna to left out (he knew it would make kuna absolutely worse to handle if he found out ryo and yuji were fucking behind his back), but he wanted Yuji to associate pleasure we his siblings and no one else. High school was full of whores who could lead his baby brother astray as what happened with kuna.

It’s not uncommon later on, for ryo to come home after late clan meetings to find his brothers passed out and naked in his bed, both of their holes dripping cum and ready for him to slide into either of them, while they’re clinging onto each other.

Future musing: yuji is the first to get a marriage proposal since ryo keeps stalling the offers for his own hand by ignoring the hints people keep giving him about their available family members, and no one wants to marry kuna because he’s a terrible person, which has both of his brothers angry and upset, that’s their baby brother.
