It's taboo because the child produced by incest has genetic flaws...reduced IQ to the point of mental retardation, teeth size and extra teeth growing in weird locations, webbed toes and fingers, and really bad mental issues to the point of be a psychopath, and etc.
Sometimes the flaws skip a generation but they show up .
I like playing games like these but please do not try to normalize incest.
do you think every girl with a rape fantasy want to be raped? do you think every guy with a rape fantasy will do it for real?
sane humans can separate fantasy from reality....
and yes, we seen what happens when you marry 1st cousin over and over and over in certain countries
it is a statistic some people dont want to see as it goes against their ideology or something
incest is illegal in civilized countries because of what you mention can happen to the off springs.
btw you might be a little late, porn industry is over flowing with mom and dad and daughter porn, it is a biggest seller, but ofc they have to add step in front to be able to sell it
but you can never stop this train...title might say something like "my stepdad blackmailed my ass" but the "dad" will say like "but you are my STEP daughter" once and then she will just call him dad for the rest of the time
unsure how many billions the porn industry would lose if they banned that category, too much I think as the government would not want to lose all that tax
