Mile High Orgy

One of my biggest passions is aviation. One of my biggest sexual fantasies is an orgy. I'd love if I could mix both things and create a big glamorous lust party in a commercial airplane. Preferably in a Boeing 747 jumbo jet. It's a classical big plane with two floors and full of space where you can spread wherever you want and create a lot of different rooms and spaces, including a bar and private rooms.
Everyone must come with masks and comply with a dress code, to increase the glamour feeling.
When the airplane reaches the cruise altitude, the whole thing starts and everyone will be free to accomplish their sexual fantasies.
I'll be there with my girlfriend watching other couples, being observed by others and interacting with multiple partners...
Then, hours later, we'll start to descend to land and we'll get dressed again and return to our seats!
