Incubus/Succubus
It is widely believed that sex with demons is possible, albeit unpleasant
or horrific. The offspring of a human-demon union are monstrous in
folklore. Some of the night terror demons also are sexual molesters. A succubus,
or demon masquerading as a voluptuous woman, molested men, while an incubus
, a demon masquerading as a man, molested women. Though sterile, the incubi
were said to be able to impregnate women with semen collected from the
nocturnal emissions of men (eew..yucky).
