Thinking about my wife with other men

Long ago, I incorrectly thought that my wife was having an affair with a friend of mine. Initially, I was a bit worried but increasingly I found that the thought of it turned me on. I was even a little disappointed when I realised my mistake. But when it was obvious she was getting attention from other guys, I used that to create a kinky narrative for our sex talk during foreplay. She bought into it and then began to shape the narrative herself, making clear choices about the ‘type’ of men we imagined her having sex with. It took a long time, but she took the initiative and turned the fantasy into reality earlier this year.
