My wife and my coworker

I convinced my wife to seduce on of my coworkers when I had him come over to watch football with me.
He was much younger than my wife. Good looking, athletic and a big flirt. He always gave my wife compliments that were rather suggestive and sometimes bold.
She always dressed different when I had him visit. She'd wear low cut shirts or go braless with loose fitting shirts. Her pants were always very tight showing every curve and usually a nice camel toe crotch. She even had one shirt that was almost a see-through. Heels were her favorite shoes, along with ankle bracelets, and sexy perfume.
The first time was fun. They both flirted so obviously that I almost laughed out loud. Neither would just come right out and say what they both obviously wanted. So, I broke the ice! I simply said, "you two want each other. Why don't you two go upstairs and fuck?"
They both looked at each other and then me and started laughing. After a few silly remarks my wife got up and went over to him and sat in his lap. They kissed and fondled each other with me sitting 2 or 3 feet away.
After getting worked up and horny as hell I stepped out of the room. I went upstairs to get my camera and quietly came back downstairs. When I returned they were both naked on the floor with her sucking his cock.
From a distance I took a few pictures of them just before my wife straddled him and started riding his cock like she was in a rodeo.
My cock was starting to swell in my pants and I was unconsciously holding my breath. I loved watching my sexy sex crazy wife grinding away on my buddy's cock.
Once they were really into the peak of sexual pleasure I walked into the room with them and took a few more pictures.

I quickly went back upstairs and loaded them onto my computer and returned downstairs. Upon returning my friend let me know he was concerned about my taking the pictures and ask me to delete them. I lightly protested but showed him as I deleted the pictures from the camera.
To this day...about 12 years later, he doesn't know I still have those pictures and have enjoyed them all these years.
That night started a six year relationship between he and my wife. On average, they met for sex about twice per week. Some times I'd drive her to his house and drop her off for a couple hours, and sometimes he'd just drive to our home, take her to his house for a few hours and then bring her home.
There were times he'd go to my house while I was at work but they would usually tell me they were going to do it. We all were so comfortable about it that it was almost funny for us to think about what everyone would think if they knew.
What my friend didn't know was I had a security video camera in our bedroom and filmed numerous hour of him screwing my wife. She also knew I was doing it and kept it our secret.
Additionally, most times when she had sex with him she'd come home dripping his juices and I'd lick them out of her and have sloppy seconds sex.
Those were fun years for all of us. My wife loved getting to have free additional sex with a young stud and then me enjoying it too.
I've saved those pictures and videos for years. I sometimes get them out to relive those fun days when my wife was able to live out her fantasy to be a slut without any danger of exposure or a jealous husband.
All these years later still bring up an almost instant erection.
I highly recommend young couples to do this for fun. Taboo but exciting.
