For many years I had the same fantasy of being abducted and forced into a life of sexual servitude. It was my own story created in my mind.
My fantasy would never side with me, it was always filled with a lot of pain, resistance and isolation.
But it was mine and I liked it.
I don't think I would enjoy going through the same ordeal in real life, but I throughly enjoyed thinking about it.
I enjoy reading those stories as well.
I think we all like to indulge our deeper fantasies, but in reality we cannot really live them, so we rely on our thoughts, and the thoughts of others who can provide them through stories.
