A mother who is the most familiar and unprotected female body (pussy) for a young man who wants to have sex. On the other hand, even though her mother, who has a ripe body, knows that it is wrong for her, she is overwhelmed by an uncontrollable pleasure. The theory crosses my mind that if it is not socially tabooed, mothers and children will inevitably devour each other's pleasure, so it is intentionally tabooed.
