Have you run into any of her past lovers unexpectedly?

Who has been out with their wife when you run into someone from her past? Do you talk about it after? In an encounter like that, how long is it before they both think about how they've fucked before?

This happens often for my wife and I, I know several guys she has been with. If we see them someone I know I think to myself "They fucked" immediately, every time it happens. There is a certain tension that I feel when this happens and it is a huge turn on.
I would love to run into a couple of the guys she slept with one especially i wanna thank him for showing her how to use those tits I'd thank him and tell him y but I'd also like to see him fuck her again she said he had the thickest cock she's ever seen and had a hard time taking it she would come home gapped and this was soon after she lost her virginity
