Very nice description of how your wife and yourself experience social nudity.
In fact, it has many similarities to the experience my wife and I have.
Differences to be noted:
1) my wife would love to experience us making love while others watch us from up close. Maybe even let them cum on her body. We've done this on cam and it was really thrilling and exciting. I never knew my wife could get so wet and horny as those times during cam sessions.
2) personally I would love to watch my wife with 1 or 2 other guys going all the way. When exploring this fantasy while making love, she usually is not open to it ... but it has happened a few times that she was so horny that she indicated willing to do so. So I'm still keeping my hopes up
