i am just wired to think that everyone should just rape aira even kohaku. idk i mean with how rough he gets treated i think he would want to take his frustrations out somewhere. the foursome was kohaku’s idea and both rinne and madara are on board bc… well who doesn’t wanna fuck two cute little boys in place of one. they can watch kohaai kiss and touch other and encourage them to give them a show… they’d both be wearing cute socks and whatnot. they swap partners too maybe (rinne-kohaku and madara-aira). madarinne also have a go with each other jerking each other off while the two kids play with their balls or something idk. and they make direct eye contact when fucking aira and kohaku ^__^ probably silent acknowledgment or just nods to each other in respect. they can make out properly once kohaai are asleep because they don’t wanna make their kids jealous… sorry i would write more but i just woke up and i’ve already left you hanging for a month feel free to add your own thoughts ><
