You came to the right place with brocon and hate fucking 😌

I truly love it when siblings are so deep into the codependency and that regularly fucking eachother is just part of their normal. Maybe since Chan is older he knows that it’s not really like that, but he lets Jisung believe it is. “Jisungie this is just what you do when you love someone. And I love you the most. You love me too right?”

So when Jisung starts dating Minho he carries that same logic to that relationship. “Channie hyung told me this is what you do when you love someone” as he’s going down on Minho for the first time. And Minho definitely thinks it’s weird to mention his brother when they’re doing something like that. He says as much too. “Jisung don’t mention another guy when we’re doing something like this.” And Jisung is like “huh? But it’s just channie. We do this all the time too.”

And that’s what starts it all. Because Minho is immediately angry. In fact let’s say this is happening in Jisung’s bedroom at home and Minho happens to know chan is home at the time, so he storms into his room and starts going off. That he’s sick. How dare he do that to his brother of all people.

Of course, Chan has know about their budding relationship and has kept his own complaints to himself. He doesn’t want to share Jisung, but he supposes as long as they can maintain their own special moments that he can endure it. It would only backfire on him if he tries to keep Jisung for himself forever.

But this guy…he’s clearly more of a threat than Chan thought. So he starts getting all possessive back.

“Who the fuck are you? I’ve known Jisung his whole life. Loved him his whole life. You just met him. You hardly know him or what he likes.”

Jisung is obviously standing in the doorway panicking and has no idea what to do. But when Chan beckons him over, he goes immediately. He doesn’t resist at all when Chan pulls him into his lap, starts kissing his neck, blowing on his ear, and he’s doing so allll while staring Minho down smugly.

But minho is already in love with Jisung. Even if he hasn’t said as much to him yet, it’s still true. He isn’t going to give up so easily. What’s going on here is weird as fuck, there’s no doubt about that, but he’ll do whatever he has to for Jisung. He’ll fight for him, and he refuses to lose to his brother of all people.

That said, he knows he has to be careful. Because Chan is incredibly important to Jisung. In many ways, minho is afraid he’s more important than anyone else, himself included. If he doesn’t approach this tactfully, he could end up being the one discarded in the end.

Even so, he can’t just temper his possessiveness and the anger it conjures. So he lets himself mouth off a bit more. Goes on about how he and Jisung have a connection Chan could never replicate or understand. That he is important to Jisung too. And that their bond grew in such a short time. Well, that’s special. Incredible. Chan shouldn’t write him off so quickly.

And when Jisung scrambles to agree with him, wide eyes filling with tears at the overwhelming situation at hand, Chan’s expression flashes with something akin to worry. Even as he keeps groping Jisung, palms moving over his thighs, squeezing them, dipping between his legs, he starts to realize Minho means more to his brother than he thought.

Jisung squirms. He had already been worked up because of what he was doing with Minho just moments before this, and something about that makes Minho gleam with pride. It may be his brother touching him right now, but Minho got him worked up to begin with.

"Fine. If you're here to stay then you better pay attention." Chan is already moving Jisung's clothes out of the way, shoving his pants and boxers to his knees and his shirt up to bunch beneath his neck. His lips still graze over Jisung's neck, one hand playing with his nipples and the other fondling his little cock as it fills out and starts to leak. "There's no way he'll keep you around if you can't make him feel good, ya know. You should learn from an expert."

That pisses Minho off. Sure they haven't done all that much yet, but they've done some things. If it wasn't for Chan and his stupid, unnatural obsession with his boyfriend then they would've gone even further just a few minutes ago. But Minho has made Jisung cum. More than once. He's used his hand to stroke his cock, whispered sweet praise in his ear as he does so, degraded him just a little for how small it is. How easy it is to get him off. Jisung cums so hard every time. He writhes and cries and begs for Minho to touch him more. To kiss his lips. To mark his skin.

Yeah, Minho knows just how to make Jisung feel good. He doesn't need instructions from Jisung's brother of all people.

So minho says as much, and of course Chan doesn't like that. But Jisung chimes in. He starts making his case to Chan. That he cares for Minho. That they do what people do when they love eachother (which makes Minho's heart swell), and that he doesn't want Minho to go anywhere. He asks Chan to be nice to him.

And it's always difficult for Chan to say no to Jisung.

So as much as it pains him, he softens a bit. His touches become less frantic, his tone simmers just a bit. But before he can say anything to Minho directly, Jisung continues. He explains to Minho that Chan is important to him too. That he's not going anywhere, and if Minho cares for him that he's going to have to find a way to accept that.

It's difficult. Minho feels such a strong possessiveness towards Jisung. He wishes he could lunge forward and break Chan's wrists for touching what's his. But as much as it pains him, he realizes that Chan was there first. That if Minho attempted to edge him out, it would only be Jisung who gets hurt in the end. And he'll never do anything to hurt Jisung.

So he decides the only thing he can do right now is prove himself. He kneels at Jisung's feet, shuffles between his legs, and looks up with adoration in his eyes. "Okay Jisung-ah, I understand."

So, so soft. Always so soft with his Jisung.

It's difficult to hold that tame expression when Chan gazes down at him, fury in his eyes. They've both clearly established a mutual agreement: they don't fucking like this, but they'll do anything for Jisung.

So when Minho leans in to kiss Jisung's leaking tip, he sees Chan's fingers twitch. They're both touching Jisung together, in their own ways, but it feels like some sort of competition.

Chan has tricks, apparently. Because next thing Minho knows Chan's fingers are slipping past his lips and pressing down on his tongue. "You gonna let him in? Your mouth is small, but his cute cock will fit just fine."

Minho rolls his eyes. Yeah, he knows. He's sucked Jisung off before. He comes in what seems like an instant, too. Now probably won't be much different.

Which is perfect for proving himself, really. So Minho tempers his pride. Waits for Chan to guide Jisung's cock between his lips, replacing his fingers, and Minho sinks down.

It's easy to take Jisung all the way in. He's so small he doesn't even reach the back of his throat, even when his hips buck at how good it feels.

"M-Minho, ahhh." Jisung winds his fingers in Minho's hair and cants his hips again. He's cautious, since they haven't experimented quite that much with this, but Chan encourages him.

"Go on Jisungie. Fuck his mouth." Chan grabs his hips and guides him to thrust, smirking when Minho rolls his eyes. If he could speak he'd say that Jisung can fuck his boyfriend without his brother's help. But since he can't, he just hums invitingly, gaze focused entirely on Jisung's flushed cheeks and lidded eyes, letting him know it's okay to take anything he wants.

Minho relaxes and let's Jisung fuck his mouth. It's clumsy and Jisung's body trembles like he's about to burst any second, but Minho enjoys every second of it. Even with Chan's eyes on him. Even with the way his intrusive hands wander over his boyfriend's body. How he touches his chest and makes Jisung whine filthily. It sounds so pretty, even with the rage Minho feels about the situation, he still can't help how good it feels to hear his Jisung like this. To see the way his eyes roll back as his hips jerk and he comes down Minho's throat.

Minho. His boyfriend.The one he really belongs to.

But it's Chan who leans down and wraps his hand around Jisung's small shaft, tugging his cock out from between Minho's lips and stroking slowly. It's Chan who whispers words of praise into Jisung's hair as his body jerks and whimpers continue to spill from his lips. It makes Minho's stomach turn with rage, and he ends up tugging Jisung off of Chan's lap and catching him as he tumbles towards the floor. This of course enrages Chan also, and he starts yelling about him "being too rough" with his little brother. To which Minho smirks and responds "ah, but that's how he likes it. You must not be familiar."

Chan is genuinely seeing red at this point and clearly not thinking straight when he gets up, lifts Jisung off Minho's lap and throws him on the bed before tackling Minho to the ground and growling "I'll show you rough, you fucking bitch."

That's when all hell breaks lose. The two of them are wrestling, trying to assert their own dominance, and Jisung is crying at them from the bed to please stop. But they don't, especially not when their cocks start to rub against each other. Everything they had done with Jisung only get them worked up, and they're only human after all. The adrenaline of the whole situation definitely adds to it. They're spewing insults at each other, just any nonsense they can think of about how the other can't satisfy Jisung the way he deserves.

The whole thing escalates to Chan flipping Minho onto his stomach and rubbing his (huge!!!) cock against his ass, chuckling about how Jisung seems pretty happy with this part of him, and maybe Minho just needs a demonstration so he can understand firsthand. Minho is yelling and going on about how Chan's cock is no bigger than his own, which is true, but at this rate it doesn't really matter. After a bit more of a struggle Chan does manage to get Minho's pants pulled down to his thighs and fucks him, holding tightly to his hips so he can't get away. They're both strong, almost equally matched, but Chan outranks him just a bit in terms of muscle.

Despite the hatred Minho feels, it feels good. It feels even better when Chan flips him on his back and he gets a good look at Jisung sprawled out on the bed, eyes wide and glued to the scene in front of him as he furiously jerks himself off. He's feeling as competitive as ever. If this is what they're doing, fine. He's going to excel at it. Especially since Jisung is watching.

He manages to get Chan on his back and crawls on top of him, straddling his hips and riding him. Minho's big cock bounces uselessly and he smirks when he sees just how much Chan is actually enjoying himself. He makes some smartass comments about how he's not so tough. How he's just as useless when it comes to sticking his dick in anyone's hole, even some random guy he knows nothing about.

Anyways, they fuck and Jisung gets off again while watching them and in the end Chan and Minho still don't love having to share Jisung but the sexual tension between them after that day remains a bit explosive, and that's fun for all three of them LOL

I got so carried away omg this could be such a LONG fic in it's completed form actually LMFAO. Sorry I started writing this and then took forever to actually answer the ask but here it is at long last.
