My wife cheated on me a few times before we married, she did at one of our friends house. So that couple knew, all her girlfriends when younger. They used to go out on girls nights every week I learned it was common. I was unaware at the time.
Some other friends knew and I knew they knew after I caught her the first time.
We moved country and got married. My parents knew what she was like after a party.
we went to a costume party she wore a very short skirt, that was at local pub and loads of guys felt her up as she stood beside them talking. She let 2 staff double team her in gents toilet so lots knew that night.
Our neighbours had a good idea as she would pass comments. ...... one night in neighbours house, she told the table how she like me and a dildo in her as she loved being stretched. 3 of the women commented I mustn’t be very thick.
I outed myself to the next door neighbor she was saying something about me flirting with a friend of hers and I told her how my wife fucks guys all over the place and i didn’t mind, good enough for her I should get some. She smirked and asked would her friend feel it.
We had a mmf with a friend while his wife was away. Never mind the guys at swinger club.
So so I have no idea who doesn’t know lol
