Exploring New Boundaries in Our Relationship

This is a story about the first time I watched another man fuck my wife.

We had been dating for 6 months. We had a great sex life. We were honest with each other about our past and she had told me that she had spent the last few years living out her sexual fantasies and had had several threesomes, had met a lot of men for one night stands and had been to sex parties where her and another girl had been gang banged by several men. It seems weird but it turned me on to think about it and I loved for her to tell me stories of her being a slut while we fucked.
One Saturday morning her and I woke up and started to fuck. While I fucked her I asked her if she wanted to have a threesome with me. She said yes so we went onto a sex sight and started browsing the available men close to our area. I was surprised to learn that she had already fucked a few of the men who popped up.
We picked a guy who lived around 20 miles away. Pretty average by all standards. He was married and looking to cheat because his wife didn’t fuck him often. Shannon, my wife was turned on by fucking married men and doing better than their wives ever could.
We prepared for his arrival. I was nervous and she was calm. She laid naked in the bed waiting while I kept her pussy wet by giving it a good licking. An hour after the invitation went out he knocked on our door. I let him in, introduced myself while shaking his hand. We made a little small talk before I lead him to the bedroom.
There laid Shannon naked, rubbing her pussy, and ready to fuck.
He went over to her and started rubbing his hands all over her big tits and then slid a finger in her tight pussy.
I didn’t know how I would react but it didn’t take long before my cock was hard as a rock and I was rubbing it from the outside of my shirts with a big grin on my face.
He pulled out his average cock and Shannon wasted no time taking it into her mouth ball deep and sucked his cock ferociously. He laid on the bed while she crawled between his legs and deep throated him. I pulled off my shorts and stocked my cock while I finger fucked her pussy. I knew that if I slid my cock into her that I would cum instantly so I just watched as she sucked his cock.
After a few minutes she spit out his cock and turned around on all fours to offer him her pussy. As he moved behind her and lined his cock up to her wet snatch, she started sucking my cock as I stood on the edge of the bed.
Seconds later this man was fucking her pussy as hard as he could and her whole body was moving in rhythm back and forth between my cock and his.
It was so hard not to cum in her mouth and I had to stop her a few times.
It wasn’t very long after this stranger started pounding her as hard as he could before he looked at me and asked where I want him to cum. Your choice I said so he shot a huge load of cum deep into her pussy. Once he was finished, she turned around so that I could fuck her. As I slid in I could feel how slick her pussy was from her juices mixed with his cum. 1 minute later and I gave her my load as well.
When I pulled out, a big gulp of cum came out of her and dropped on the bed.
The stranger got dressed and left. Her and I made out and I told her how hot it was watching her and how I wanted to do it again soon.
Later that day, she called up one of the men on that site that she had fucked before. A guy with a fat cock that she loved and I watched as he fucked her in front of me.
Since then we have been together for ten years. Married for 8 of them and I have watched her fuck at least 100 men. From her bringing home a stranger to her being gang banged I’ve watched and participated in it all.
