The "off-premises" aspect isn't really that big a deal. There is a nominally "off-premises" club we go to that we have had sex at (oral) with another couple, albeit in a "back room" that is set aside for this sort of thing. The owners allow it to go on, as long as it's done without too much ostentation.

However, in this case the issue is not your hubby boffing this gal in the club, but his boffing her at all, as relates to what ground rules you had previously laid down for each other.

If you had not already established a "we both play or neither of us do" rule, or some variation on that theme, then you don't have a bitch coming.

But then this is one of those things that should have been settled long before you ever tried hooking up with your first couple.

On the other hand, if you already had such a rule, and he did it anyway, then he was out of line and should be called to account for his actions. And if this was the case, you need to back off from the lifestyle until both of you get a better handle on what is and is not permissible.
