Well, in one sense, I can see how a demonstration of a loving couple in the act could be better than the sordid things one learns on one's own. On the other hand I think watching one's parents having sex, let alone being forced to watch it could do serious damage. If the intent of the parents was purely educational it MIGHT be viewed as non criminal, but I think even if the thought was sincere, the bad here for the child likely outweighs the good.

In this instance, as you have read, it was a woman and her boyfriend. I can't help being suspicious that he would approach the girl at some point in the future, and the mother would not disapprove. Or in time, there would be a different boyfriend, and the mother would be having sex with the new boyfriend in front of the daughter.

This was just a prelude to involving the child in the act with them. There is not excuse for this kind of abuse and they should both be neutered and jailed.
