nah thats crazy. I'm not sure her eating him out was necessary bro
According to ye olde folklore it allegedly was.
What she did is called Osculum Inflame or "Kiss of Shame" and it was believed to be a ritual practice that witches would use to pay homage when meeting Satan and his demons.
The practice originated from confessions during the witch trials while "witches" were undergoing torture.
It's also said that women undergoing analingus with the devil allows the devil to seduce them. But to be frank if a girl is already eating your ass I'm pretty sure she's seduced already lmfao
