Wife's Fantasy

Things may be getting a little out of hand. My wife has a new fantasy she wants to fulfill. She wants to be blindfolded in a hotel room and have anywhere from 6 to 12 guys (the number keeps changing) come in one at a time and use her anyway they want. She said she doesn't want me in the room but to play door man controlling the guys in and out of the room. She also said she doesn't want to know who any of the guys are and she doesn't want them to speak. She said the guys can do anything they want to her and she will not resist. However, she doesn't want any "rough" stuff or "weird" stuff just regular sex. They can use her mouth, her pussy or her ass. She said she doesn't want any condoms and any or all of them can fill her pussy with cum if they wanted to. Actually she said all of them could cum in her pussy. Although it sounds really hot and we have done some crazy things (and experimented) over the last few months but I'm not quite sure I am up for that level of "sharing" her. Am I nuts?
