How I found out...

It was in the 80s, when many younger people were "punk".
My fat wife was "in love" with an asshole half her age.
I was not allowed to watch or even hear stories about their activities.
One night I attended a party at an old building downtown where some of the guys were staying while they did some work on it. I worked 3rd shift, but was hoping to at least see my wife. As a hardcore cuck, I liked watching them together in public.
Well, they did not show up til after I had to go.
Someone I did not know said "I wish Gino would get here with that crazy old fatbitch that follows him around, I need another blowjob"
That is how I first learned that he had my wife doing his friends.
