This is my first post, all comments are welcome. I apologize for my non-native English.
These events took place several decades ago, before digital photography and the Internet. Live sex was mostly illegal, unless it happened on private clubs, this funny institution which was considered as private as a home. I don't know if that is still the case.
My wife was introduced to nude live modeling by a friend of hers, initially by posing partially and then totally nude for a certain Mrs. Dawkins, an amateurish painter in posh Hampstead, London.
After some interesting incidents which embarrassed her as Mrs. Dawkins exposed her nudity to Mr. Dawkins and other members of the family, she was invited to model for a Camera Club where the artist's husband was a member. Of course, she was expected to expose partial nudity, or more. She found the challenge exciting and accepted it, not knowing exactly how much exposure it would entail.
It seems that she attended the members expectations, because after three or four sessions, Mr. Dawkins suggested that she could perform at one of the special Erotic Nights at the Club. She was vaguely told that they expected her to interact with male model partners. If she knew what those interactions entailed, she didn't let me know.
She accepted not only for the money, which was much better than the usual pay for posing nude for the Camera Club, but as she told me about the new proposition I noticed that she was clearly excited and aroused.
To add context let me say that we had always been quite open to explore sex within our marriage or out of it but she is quite shy and would only talk about her exposures or partners when we are having sex, which very much spices our encounters.
That is why on her first Erotic Night I offered to pick her up after the session, on the vague expectation knowing more on her performance.
This is the story of this attempt, how much my expectations were satisfied and some unexpected development after the session.

After her first Erotic Night session
I tried to convince myself that I was going to pick her up after the show because it finished at 1 am, and she will be pleased to have a lift at those late night hours. But the real reason was that I was really anxious to know more about the show, and perhaps to have the opportunity of having a glance at her performance.
At those early hours of a Sunday it was not difficult to park legally near the club even being in Chelsea.
Reaching the club I was led into the small entrance hall and was asked to wait for the show manager. It was she that could put me in contact with my wife. In the back of my mind I expected to meet Mr. Dawkins, so I was a bit surprised when a smiling teen approached me asking how she could help me.
I explained to her that I was there to pick up my wife after the show, which I supposed should be finishing by 1 am. She told me she knew the performer was married but was surprised by her husband being aware of the kind of session she was performing. I wasn't aware, but didn't correct her.
She offered me a drink which I accepted mostly to give my anxiety a break while she took one for herself.
"Yes, the main show finished at 1 am, that's the photo session with erotic and sexual posing. But if the performer accepts, we offer them an extra pay for what we call the erotic sketches of around 20 minutes each, with an intermission of about 10 minutes. And she accepted."
"Could I talk to her, to see at what time I could come back to pick her up, or if I should wait for her?" I was almost sure that she wouldn't let me in, but asking didn't hurt.
"I'm afraid she could not be interrupted now. The first sketch is underway and she is being fucked by her partner. Of course the audience will not be happy if they had to stop." I think she was being bold either to tease me or to test me.
"So perhaps I could wait here for half an hour to let them finish this act?" I don't know how I managed to hide my instant hard-on and pretend that what she just told me was absolutely normal.
"That's up to you, but she will not be free in half an hour. Today we have four male partners available, and she accepted to take part on the four sketches. So they will be fucking her for the next two hours, roughly half an hour for each of them."
Of course, I was terribly horny by being so close to her being fucked while exposed to an audience which was not only watching but taking pictures of her. And further, being told that this would continue for a couple of hours.
