A foursome doesn't necessarily mean that all four parties will physically interact with each other. It could be Dowon and Beom on one side of the couch. And Lil Bro and Taeju can be on the other side. They'll be in the same room, but both couples will be with each other respectively. It's just like in a threesome, sometimes...for instance, when its MFM, the two males could be interacting with the female at the same time, but never physically touch/interact with each other.
Anyway, group sex can be done any type of way. Not everyone has to interact and touch everyone. This is so stupid that I'm explaining this, but I felt like you were thinking that the brothers were going to have sex with each other too. That's what I meant by wanting to see a foursome. I'm hoping others were meaning the same thing, though I can't speak for them.

Hey there Potato!
I see what youre saying and I respect your opinion! I guess I don't see it as weird persay (is it spelled perse??) because I'm a little open when it comes to certain things. I feel as long as the siblings aren't interacting physically with each other.
Also, a lotta times when you're dealing with Couple Orgies, you're not really paying attention to anybody else. Yes, some couple switch partners and yada yada (which would make it a Swingers/Swinging session), but in a regular Couple Orgy, if it's good enough, your mind is on your partner and what yall are doing. You're not even paying attention to the other people. It's the act (which would be having other people in the room) that gets you off. The taboo of it, I guess. I, personally, would neeeever do it with my sibling(s) in the room. But I would watch it in a manhwa.
yall are fuvking weird theyre brothers...
