seeking advice on setting up a gangbang

#1
So my wife says she's ready to make the leap into group sex and wants to have a gangbang. She wants me to set it up for her and I of course want it to be a great memorable experience for her....but I have no idea how to go about setting one up. I've hooked her up with single guys before and such, but never had an organized "event" like what she desires.

Anyone out there with experience care to share tips on planning and organizing to make sure everything works out? Any advice would be helpful. Thanks!
