Let us know when you know your wife is out getting fucked!!!

Yes. I fully agree.
My wife enjoys to be touched and even fingered in a public place like a bar. So she will definitely go for that and allow him to bring her to orgasm there.

The big question is how it will continue. Can he seduce her enough to have her go with him to his place?
I would guess that the maximum she is willing to do is to go with him to his car and then take it from there. It is one of her big fantasies to be fucked in a car. But AMG convertible might be a bit narrow for that 😉
I asked her whether she came to him…
Her answer: I dont remember.
