Succubus

A Succubus is a female that feeds off of sexual energy of men. It is possible for a Succubus to kill a man by having intercourse with him once or sometimes more than once. Folklore and myth have made Succubus out to be fallen Angels looking for revenge against mankind for being above them in Gods' eyes.

History
Lillith, Adam's first wife, refused to submiss to Adam. She felt a sexual urge and Adam was in her eyes inadequate. Her craving for sexual pleasure was so strong that Lucifer bestowed to her the power to take the life force from those she had sexual intercourse with, that being men.

However, if she were to kill a man during intercourse then that man would come back as an Incubus himself, having the same urge as Lillith had. This process would continue, creating more and more Succubus/Incubus.

God became so outraged at this and created the Great Flood to wipe them away and purify the land once again.

However, Lillith survived as did a few Succubus/Incubus. They became more careful, learning to control their hunger and learning when to stop before killing another, turning them into one of them.

Children
If a Succubus/Incubus has a child, they will age normally and will not receive their powers until around the age of 20-22. At this time they would stop aging and have the ability to suck the life force from those they had intercourse with.
