I've taken the wife when he was there and when he wasn't and both are exciting.
On a business trip to San Jose was the first time the husband was there. She was his sub and he directed all the action. I was simply the cock. It was a lot of fun.
A different time in Pittsburgh, again on business, the husband watched and held her hand, but I was in charge of the action. That was fun in a completely different way.
Other times all three of us have been involved and all acting of our own will. Different again.
I've had him drop her off at my hotel room and wait in the car. A lot of fun.
And of course there's been plenty of times he didn't know at all.
