Visual Guide - Succubus
The denizens of Lilith, succubi sit astride a man's prone body and have their way with him.
Often taking the form of beautiful women, succubi will instantly turn into miserable hags if confronted with their real identities.
Monks in monasteries are often visited by these troublesome spirits who inspire dirty dreams and tempt the brethren with their lusty ideas.
In the Middle Ages, fearful monks tied crucifixes to their genitals before retiring at night as protection against nocturnal visits by succubi.
