Ritual that makes you rightful heir (Patreon)

Everyone in Egypt knows, that containing Horus' seed inside of you gives a permission to rule, even if you are a female pharaoh and everyone expects male-ruler. She only needs some kind of artifact to force her god to obey HER will and then, just make him cum inside, filling her with the claims for the throne and making her Rightful heir. No one would ever doubt her rights!
