Succubus

From the introduction:

Players take on the role of succubi, sexually alluring demons operating within the modern world covertly.

To sustain themselves they must consume the life force of mortals or other succubi, usually by giving pleasure to a victim, or forcing that pleasure upon them.

They lead a secretive existence lest religious organisations learn of them and come to destroy them.

They wrestle with the morality of what they do to survive, and try to remain as human as possible, struggling to avoid transformation into a flesh eating monster known as a lamia.

They compete against other succubi for power, privilege and territory, plotting and scheming to ensure their dominance, and therefore continued survival, within wider succubus society.
