Absolutely, along with many other encouragements.
I very nicely recall a few years back when first sharing my slutty wife a few times we were driving somewhere for an evening out. Naomi was dressed to the nines and looking very sexy. I could also tell she was getting turned on and feeling very sexy too, when all of the sudden she reached over to stroke my crotch and asked "when do you think we can share my pussy again soon?".
As well as when Naomi knocks and waits at the door of cheap motel room, to see whose big black cock I have arranged to be fucking her tonight.
Yes, we both love people seeing and knowing what a sexy whore Naomi is. This includes sometimes being out at a club, after dancing with a guy for a while, watching her leave with him for a little while, to then come back in, making certain we connect eyes as she licks her lips very slow and sensual, telling me she just gave him a great blow job in the parking lot. Many times to be followed by giving me a deep kiss to taste the cum in her mouth.
Everyone knew your wife had just fucked him, when they walked back into the party.
