My introduction to hotwifing and swapping [MFM]

I am not sure really where I should start this story. This starts all the way at the beginning. Ever since my wife Amy and I first got together, I seemed to be intrigued by her sex life before me. I know every detail that she can remember about all her former sexual encounters. Nearly twenty years ago my wife worked Mark who flirted with her a lot and she liked the attention. At that time, I did not know I wanted her to do anything about that flirting, but I did not mind. Getting that extra attention always got her in the mood to have extra fun with me.

Over time, we have become great friends with that co-worker and his wife Lisa. There has been a lot of teasing and a lot of fun, but my wife had always resisted going too far. My wife does not like to give oral sex where Lisa loves doing it, so my wife has given me a BJ hall pass with specific ground rules. I have used it a few times and it has been awesome but that is a story for another time.

My first time watching my wife with another man [MFM]

I typed this up in response to a comment in Ask Reddit After Dark. I realized I might as well share it here since I already had it typed.

I was not sure how I would feel about it until it actually happened. The night it happened was sort of a swinging experience. My friend, Mark, and his wife, Lisa, were over visiting to BBQ, swim and enjoy the hot tub. I had already gotten permission from my wife, Amy , to play with Lisa and we had done it several times before including MFM threesomes with Mark, Lisa and me.

I was in the swimming pool with Lisa and I was inside of her. I looked over in the hot tub and Mark and Amy were apparently going at it. She was riding on top of him facing him while he was seated. I told Lisa that it looked like they were fucking. The hotness of seeing that made me finish right there inside of Lisa. Lisa said she did not think there were actually doing anything. Earlier in the evening, Mark had taken Amy for a ride in his new sports car an they had cooked up a ruse for me. They decided they would act like they were fucking and let me think they were really doing it. That is indeed what was going on.
