Probably not a great idea.
Unless your Mrs knows your on here? Then maybe then you could (not through here) suggest a 3sum.
Generally though, these situations end badly.
The opening statement on your profile is “Discretion is Paramount”
I would say the overwhelming majority of people on here it is their Guilty Pleasure and to be kept discreet….
Leave well alone
"Looking for advice my Mrs mate is on here and I'd love to fuck her but they are very close so would you make a move or not "
I mean what could possibly go wrong!?
