Eyes wide shut

another of my fantasies would be to attend a party like the one in the movie eyes wide shut. Id love to walk in to a mansion where people are all anonymously having sex with anyone there. It would be like a swinging party but it would have to have the same atmosphere as the scene in the movie, classy and very sensual. I love the theme of the scenes party and ive masturbated to the thought of me being in such a place or something similar. What are you peoples fantasies?
