His greed sickens me

I mean it works for them?
Alternative would be he either choose one of the twins thus breaking others heart and probably destroying sibling relationship. Or choose neither and all be miserable...

It was a joke! °~`

its just bad writing man. no need to think about it any deeper than that

I dont think its bad writing at all unless you have problem with polyamorous relationships (which I dont)

I don't think polyamory is the problem, it's that two BROTHERS are having sex with one person, potentially at the same time which is incest no matter how you shake it

Its only incest if they do it with each other.. which I doubt since they are both omegas and are mated to another person (not to each other). But regardless lets say its incest. What exactly is the problem other than "moral" one?
