Westermarck effect makes whether it's "okay or not" a moot point

No. But if it was blood related, then yes.

It's not okay. You can only marry your sister if she's blood-related

>Westermarck effect
humans really are worthless creatures, raising a wife for your son sounds based.

Unfathomably based. NBRfags need to get the fuck out.

>NBR
fuck that shit
BR or nothing

NBR is just a childhood friend i disguise

westermark effect is a reduced attractiveness post puberty to a related member of the opposite sex raised within a family setting before the age of 6.

Also the Incest avoidance is seen more in girls.
So it seems in this case that it would have a much diminished effect as Sachi is the younger party and the most interested possibly because they are NBR.

it's more like a 1vs1

>childhood friend curse
It's over sachibros

Weirdly you can find some very unusual census reports from roman era egypt that imply full blood sibling marriage but with a sizable age gap.

>NBR is just a childhood friend i disguise
But they don't betray?

>prefering to marry a complete stranger instead your NBR imouto
Fuck off

This user raises a good point.

>nbr
Absolute trash, might as well be strangers.

Why are western mutts so obsessed with incest

>western mutts so obsessed with incest
>implying

How do I learn to disguise people as well as you do?

>blood related
>complete stranger
choose one

There's nothing wrong with NBR.

No. All marriage is just a way of coping with an nbr girl and trying to make her your family.
A brother should only be allowed to actually marry his real blood related sister.

what are you implying step-bro~

It is also pseudoscience with no actual test data, just post hoc Texas sharpshooting.

Without love it cannot be seen.
