I have an idea I call "The Spirit of Lust." In it, the "spirit" is sometimes a dispersed presence, and infects/affects a number of people, like "school spirit" can get a crowd going. When "generalized," the Spirit induces an orgy. Some of the participants are willing, others are not, so you get bawdy consensual sex and rape simultaneously.

Then the "Spirit" becomes localized, and resides in an individual where it takes control. The Spirit of Lust may cohabit the person with Pride, Power, and other spirits, making it especially evil and sadistic.

One of these days...I'll get around to writing that. My idea is to have the Spirit of Lust present at a girl's sweet sixteen party, and she is devastated as her wonderful party deteriorates into a violent, hedonistic orgy. Then, when everybody is sated, the Spirit "gathers itself together" and enters one particular person, who overpowers and rapes the girl.

As with most of my stories and ideas, she'll be wearing a beautiful, full-length silk gown, which will be shredded to pieces (above the waist) while her skirts are pulled up, exposing her virginityh to the predator's vicious assault.
