An impromptu large family of 7 men and women - all family communication is sex! ? Even if we are not related by blood, our mind and body are one.
A father and mother whose stepchildren repeatedly remarry. Children raised in such an environment may be brothers or sisters, but they are not related by blood. Every day we live together as a family in a literally improvised state. Because the moral values of their parents have collapsed, their children are similarly detached from the world. Therefore, this situation can be said to be abnormal as the target of sexual desire is directed towards the family at hand. But for this family, it's normal. Mother and son, father and daughter, brother and sister... and an orgy. It's hard to understand, but this is common sense in this family.
