Actually the fact that my wife was my slave was never mentioned that first night when we brought Seri home with us.
We kept it very low key despite the outfit, which didn't distract in that club considering all the fetish wear the patrons sported.
If I rember correctly my wife and I didn't even field any slavery questions until after the first thee dates. Seri mentioned at dinner with us the next weekend something to the effect: "Are you two into bondage or something?" LOL.
Yes Ozme, alltough having a woman on my arm most of the time, I found the wedding ring alone was a girl magnet.
I can't count the times I was approached in bars by different girls, some brazingly infront of my wife and Seri (though most would wait until the girls were away from the table) and well over half of those were married. It is a most interesting phycological condition to observe, especially on those nights when we were allmost out right advertising our kink.
To be honest though, I think it is more a combination of projecting self confidence in conjunction with approaching the woman that is ripe to embrace her true nature, as opposed to finding the pre-existing submissive girl.
I have found throughout the years that most wemon; when in the presence of a dominant, sence his strength and crave to submit even if only subconsiously.
