Over the past few months, I have been with three single males. Two of them have been friends of my husband.
The other one was one of my co-workers. In each case, it was up to me to approach each to get a feel for their outlook on spontaneous sex.
Then I would bluntly ask, "What about having sex with me?"

Friday afternoon I was online with a married male. His profile claimed he had permission to be with others. He attached two photos for me to decide.
I invited him to our home for the early evening. At first, my husband was a bit put-off because I didn't discuss it with him.
Now he is really upset. Seems I enjoyed the stranger's big cock a little more than I should of. He was the first I allowed to cum inside of me.
