It's funny how some people though / wanted an orgy( some orgies involve exchanging partners) or the having sex in front of each other... But let's think about it, that would be so out of character especially for the sacred beasts like they would naver alow others see their chosen one getting pleasure especially NAGIII LIKE IFBRO WAS DRUGGED TOO AND COULDN'T RESIST HE FIGHT IT AND DO HIS BEST TO HIDE KOTONE WITH HIS TAIL
Not saying other SB aren't like that too( they might stay but they won't change partners) but i know nagi won't allow a look
Right they are naked in front of each other but let's remember it's a only man's world and it's normal there lol
So yeah no orgy between the SB and Chosen ones, cuz that would be so out of character and context, even the scene with tora and wu there was a wall a WHOLE room between them lol
