A fun premise, but I wonder how practical it is.
Because you would need dialogue for every character that reflects the existence/absence of every other character
I got a lot of attention from my mother's friends as a kid, so that should explain my shota/milf/mommy kink
I used to be a pretty lonely kid, so maybe me wanting a sibling turned into an incest fetish
Now the bestiality and femdom I really can't explain
