Cool thread. Sorry I didn't notice it earlier.
Here is our definition of hall pass:
Either one of us can have sex with anyone at any time. We do not have to let the other know beforehand. We do have to let the other know after the fact. We have had this in our quiver for the last 10+ years.
Now, what does that mean practically? Here are some scenarios that my wife has had: She took a trip back east to see her family. She was there for 4 nights. Prior to going, she and I went through SLS to find guys who looked like they would be a fit. She narrowed it down to 10. I started the conversation with them. I explained exactly what was going on. If they weren't total idiot/douchebags during the responses, I gave them her number and they talked. She sent me post sex pictures every night :) There are a few single males that we have played with in the past. One lives in walking distance of where she used to work. She would go over for a nooner during her lunch break. She has little to no desire to go for a weekend with someone.
For me, there is a 24 year old that I had hooked up with at a party my wife and I attended. Her and I were texting each other. She got really flirty. She came to my office and we had fun. I told my wife after the fact. She said, "Glad there is no one in your building and you got that sofa bed for a reason!" There isa SF we have been with on occassion. We were flirting and I suggested I'd get a room for us. She agreed. She lives 40 miles from us. So I got it close to her, she met me at the hotel and we went to town. I sent my wife pictures after the fact. There is a couple we know who live in LA. I, used to, have to go to LA a lot for events. If I had to be at the event early in the morning, they would let me sleep over in their guest room. We would have sex. I have little to no desire to go for a weekend with someone.
So for us, this works. My wife has sent to me to parties solo because she got sick. We have yet to meet all these horrible people that others describe. We do not go out looking for this. If it happens, it happens.
Back in the 90s, we ran into a couple that was not married to each other but married to others. It was very interesting. One of their spouses had a debilitating disease and the other was in a car accident and paralyzed. This is so long ago, it was in an AOL chat room that they approached us. We talked for a bit and once they felt we were a fit, explained their situation. One of the spouses was completely OK with it and encouraged it. The other spouse knew it was going on but didn't want to know about it. Their respective spouses knew of each other's situation and what their spouses were doing. I know that is convoluted :) The 'couple' said that we could verify if we wanted with the spouse who knew. That the other spouse, not possible to verify. I figured that they were either incredible bullshit artists or were telling the truth. I called the spouse. I talked to the spouse. It was the female who had the disease. She verified everything. She said that she encouraged him to still be sexual and that he is a great husband and father. She told me about the other spouse who was paralyzed. She said that he had not come to terms with his situation. She said he knows his wife goes out and has sex, is not pissed about it, but doesn't want to bring it up. She felt it was a pride issue. So some of these 'far fetched' sounding scenarios are true.
