Married to a slut

I married my wife nearly 29 years ago, shortly after tis I actually caught her fucking 2 young lads in a car not 200 yds from our house at 2.30 am . I was completely taken by surprise even though I knew she had a history of being a slut, and all the time I had known her she had had a string of lovers, I was an extremely jealous boyfriend and husband, that night had it not been for the fact I was to embarrassed to tackle her there and then I wanted to confront them there and then, I found my self creeping around the car trying to see what they were doing in the back seat with her.
The car was shaking and rocking, the windows were all steamed up, I could hear them talking, the slapping of flesh or the squelching of sex ,, everything from her grunts and moans to the deep "UHH UHH and the sound of the squelching ceasing briefly before the car rocked and shook as the rhythm built back up, I listed to them talking as they swopped over as they took turns, guessing that the one had cum as he climbed off her and made way for the other, nearly getting caught as he opened the door getting out to urinate by the side of the car laughing telling his mate how "I can hear you sloshing in my mess"
I moved back when he got back in the front seat leaning over talking to him and egging him on until he to had finished in her and they all stopped for a smoke, before carrying on again
it was coming close to daylight when I saw them starting to get dressed when I sneaked away back home
little did I realise how this night was going to change my life for ever @geoffry on the community
