Trading voyeurism with your brother.
We only did it once, but it took 4 months or so to get things equal so both got to see the performance. He hid in the dark in the next room watching me f*** my wife and I did the same at his place watching him with his wife. The only rule was we had to perform reverse cowgirl, so we could full on see each other's wives in the most complete way from head to toe while riding us.
The secret we learned was how each other's wife got off. What did their bodies do and what were their noises they made when they each came. How much they put their bodies into it and what their tits looked like bouncing during the sex act itself. We now know one another's wife's secrets. We each hinted to them about how much fun a foursome would be but both of our wives shot that down instantly. Their feelings about an MMFF is not exactly a secret.
