request to find a vintage porn

I know this is a long shot, I have scoured the internet but cant find it. here is a little of the vague details I remembered from watching the vhs of it from the 90's (i am not sure when it was filmed)... It was a "professional" porn not amature. There is a room full of men that are watching a sex show on a stage, it had some type of host on stage. One of the men is chosen from the crowd to have sex with a woman. All of a sudden the mans wife shows up on the stage yelling at him for being a cheater, so she says its her turn and he has to watch from his seat in the crowd while she calls over a man to fuck her on stage in front of him and everyone else.
I know its vague but that is what I remember from it. good luck to all who trys to find this impossible to find video.
