Getting into such a lifestyle, you have to imagine there are going to be some kinky aspects. When I met my Mexican wife I did suspect she had a wild side. Months after our marriage we discovered we were a Stag/Vixen couple. I liked watching and she liked "performing".
If we did the MFM 3some, she didn't want to do it at our house or at a hotel. She wanted to roleplay the part of a prostitute who got fucked by an influential celebrity in his limo. And I would be the driver.
Well, she loved being the whore, the celebrity was a guy we would find on Adult Friend Finder, the limo was our minivan and I was still the driver.
I'd have to explain this whole scenario to the other male and that he'd be banging my wife in our car as I drove them to a more isolated area.
What can I say, she made it work. She'd start taking off her clothes as I drove. So did the guy. I'd park. And they'd go at it. It was wild seeing my wife put a stranger cock into her pussy while she looked at me. I could read the expression on her face,
"Yes, this is what you want to see, we don't even know this guy and I'm putting his dick in my pussy". She was right.
After the deed was done, I'd drive the guy back, wife and I drove home and she'd get a second load from me as I told her how naughty she was.
