Help understanding wife fantasy

After a few Gins, my shy wife that had a conservative upbringing finally told me her fantasy.
Please help me not mess up the nuances.

I really want to understand what she meant.

She only shared this after I told her that it turns me on when other people want her. That my secret fantasy is to watch her with others and never about me with anyone else. I find deep peasure in your pleasure.

She said I could not be serious? Is this a trap?
Reassured her I was being honest.

I asked her what her fantasy is?

“You will judge me. It is naughty….
Bill Clinton and Monica L.
I want to be in charge.
I want to be someone’s naughty pleasure.
I want to be in control. “

Seduction of the reluctant but secretly desperate?

She would not go into more detail.

What would this look like in real life if made into a reality?

How would I make this fantasy a reality for her?
Can anyone suggest a movie example? A novel?
It would not involve me.
I would watch unseen.

We will most likely not act on this but who knows.

Would really appreciate a woman perspective and interpretation.

We are happily married and very honest and open.
She has however always been a bit sexually reserved.

Bit more history bellow.
She was not happy with her body and decided to change.
She has been exercising religiously for over two years now and went from non athletic and a bit overweight to super fit and sexy.
She is finally feeling more confident and comfortable with her own body. Her dedication and transformation has been amazing.

It is great to see her climb out of her shell and feel confident and happy with herself.

Not complaining about how this is benefiting me either.
