It was our wives´ idea, not us. My opponent was reluctant, too, but they talked us into it.

Be a man. This includes not listening to your wife's dumb ideas. Now you know better

I´m afraid you are right. That was a humlliation fest. Right after the fight, the other guy went to take a shower (we were in their place), to which the wife said to me "You go after him", to which I replied I would shower at home. Then she, half-jokingly, said "I´m not asking. You better comply, or I´ll get my man to beat you up in front of your wife again." She said that while looking at my raging stiff.
Once the guy came back and I was heading to the bathroom, I could hear she saying to him "Hubby, even your sweat is stronger, I can barely smell his!", to which the three of them laughed out loud.
And to top it all off, when I came back from the shower, my wife told me she was spending the night there, and the other wife added "Don´t worry, we´ll take care of her". She made it sound polite, but I take it as "We´ll have a threesome with your wife so leave us alone". I suspect that was what happened when I left.
