Sex-Oracle

Recently, I've been having this reoccurring dream, and I've got to get it out of my head. The woman in my dreams is an oracle, like those at Delphi during the Greek heyday. I read once that the oracles, living in caves over sea floor vents or deep sea volcanoes or something like that, saw their visions because of gas build up in these places that made them hallucinate. The oracle in my dream wears a full faced leather mask, and a sheer gown. Men and women come to the cave to visit her and get her to tell their futures, but in order to do that, they must pay her in sex. The heavy breathing has sees her inhaling more of the fumes and the hallucinations begin as she closes in on orgasm, making everything colorful, sharp, waving. The sound grows more beautiful, the lights brighter, her vision shimmery. But this does not scare her. She likes the feeling. She orgasms intensely as the room undulates and once all is finished she retrieves a small velvet bag from which she pulls a set of divination tools, sometimes casting shells, sometimes tarot cards, sometimes a pendulum, and she tells her partner that she sees a recent lover that they won't be leaving anytime soon. Finally I see the partner's face and I know that it's true. They are under the oracle's spell.
