um...molestation is not incest.
Incest is when the penis enters the vagina and ejaculates.
There is a possibility of offspring.
I read that this boy was molesting three females in the family. That would be touching, looking...etc.
I did not read that he had sexual intercourse with any of them.
It was sexual relations. He was touching them, and coming on to them, in a sexual manor. Don’t get all Monica Lewinsky on me.
He removed the underclothing of the four year old sister and forcibly fondled her naked vagina. He was almost 16 then. It was written down as a felony which implies digital rape.
