Shared wife- great memory

This happened 20years ago we were in our 30’s two kids very young

Wife ex is a family friend , him and I don’t really connect but wife still finds him attractive.
He is an electrician and she asked him to stay with us to do some work around the renovations we were doing.

Bedtime chat with wife was around does she want to fuck him again - she reluctantly said she did.
The next day I took the kids out of the house for a couple of hours to leave them alone.

When I got back I couldn’t tell if something had happened or not everything was normal.
That night I asked the wife did anything happen she said yes. I got instantly hard and she wet.
While I was sliding my cock in and out of her she told me all the details , sucking / being eaten / fucking different positions.
I was very turned on and didn’t last long.
The next morning when I woke up I encouraged her to give her ex a wake up headjob.
She was concerned about the kids waking up but our kids slept in a lot so I pushed the point.
She agreed and went to his room
I was listening while wanking
Could hear rustling and movement but nothing definite. Then I heard one moan not sure if it was my wife or the EX.
A few minutes later she came back to our bed I was super hard.
I touched her cunt to fund it super slippery and full
She wanted me to fuck her
I filled her
This was a first for me with sloppy seconds and a first for her having two loads.
It’s a great memory
