okay

you can commit INCEST, and not be worried about getting caught,
UNLESS, your that REALLY CARELESS.

with BESTIALITY & PEDO, the stakes are much HIGHER.

you will have to worry about someone seeing you with a CHILD or
a ANIMAL, doing INAPPROPRIATE THINGS.

plus, you will face SEVERE JAIL TIME. with incest, it's really hard to
prove the act itself is being committed.

regardless, whether it's between siblings, offsprings, or child/parent.

a child can come out years later, and report the situation(s) to the
parents or authorities. which result in CRIMINAL PUNISHMENT. ( pedo )

some states don't have a STATUTE LIMITATIONS. while others may
have them in place.

when it comes to animals, animals can't speak. but, if your caught or
their is HIGH SUSPICIONS from a VETENARIAN, of abuse to an animal,
you can be brought up on numerous charges.

with incest, the relationship may continue on for years to come or stop.

this may result in a child moving away, which their may have been a
parent/child relationship

siblings being involved, and one of them got married and moved away,
took a job or went to school in another state.

( offspring ) can come under parent/child.

then again, it could be a NEPHEW/AUNT, GRANDSON/GRAND-MOTHER,

NIECE/ UNCLE, or a NIECE/AUNT. or whatever the combination may be.

there's WAY TOO MUCH AT STAKE , in trying to have relationship(s)
with a animal and/or child.

the only exception i can see is, if the child had feelings ( urges ) to
fuck their parent(s). MORE SO, between son/mother.

it's behind closed doors, you know who lives under your/their roof,
and no worries in getting caught.

OUT OF SIGHT, OUT OF MIND.

 

How about incest where no children are produced?

 

How about just not fucking your sister?
