An Unexpected Evening by the Poolside

It finally happened.
We finally swapped partners. Having her has been a long time fantasy.
Let me give you a little history first.
I started working with a lady named Sue about 15 years ago. I was instantly attracted to her. We were both married, but we became friends fast. We started doing things as couples but her husband was a puttz and couldnt get close to him.
My wife and Sue hit it off great and became close friends.
I was always attracted to Sue and I felt it from her also. But we never crossed that line.
She got divorced a few years and Sue hung out with me and my wife a lot. One drunken night, me and her was drinking at a bar alone and I kissed her on the cheek and then on the lips. I asked her if she wanted to go back to her house. She said she wanted to but she wouldnt because i was still married and she was friends with my wife. So she put me in my place but said she would never tell my wife about that night.
So i never tried hitting on her again. But she is so touchy, feely with me it drove me nuts. But i marked it up as we will just stay friends.
She started dating a guy 10 years younger. We all get along great.
We became best of friends. They got married.
we could see the attraction between my wife and him. My wife especially has the hots for him.
But we took it in stride as good friends.
Last weekend we had a few couples over to swim and party. It got late and everybody else left except them.
Sue and my self was sitting next to each other at our pool side bar. Just talking. My wife and Rob were back in the pool in the deep end close to each other. Just talking . We couldnt hear them but see them.
Jokingly, Sue ask what they were doing over there in the dark.
My wife Hugs Rob and says I'm hitting on your boyfriend.. Rob looks at me and said, I'm trying to fuck your wife. I asked if hes having any luck.
Next thing I know. They start kissing. Sue and I looked at each other and she says , Oh hes wanted to do that for a long time.
I stood, reached down and kissed Sue. We started kissing and it got heated from there. We looked back at my wife as they were kissing she was throwing her bikini top on the side of the pool. There was no doubt where this was going.
Sue said shes cold and grabs my hand and said we are going inside to get warm.
We walked in and walked to my bedroom. We pulled off our wet clothes and got on the bed. We started kissing like teenagers. I devoured her body with kisses and started eating her pussy. Licking from her ass to her clit.
It was time to fuck her but she asked me to wear a condom. I had to walk into the bathroom to get one. It gave me a chance to look out the window and see my wife riding Robs cock in the lounge chair.
I started fucking Sue missionary. But soon put her on her knees and took her from behind. I was looking down at the beautiful ass i had wanted for years.
I was buzzed and wearing a condom, I fucked her for the longest time. Sue said take the condom off but dont cum in her.
And I did. Finally able to cum I pulled out and cum on her ass.
We flopped down on the bed to see Rob and my wife at the doorway watching.
They had already planned to stay the night. They walked away and Sue and I cuddled . Next thing I know. Shes getting back under the covers with me. She went pee. It was 4:30 am. She snuggled up close. Me holding her my cock started to rise.
I layed her flat and got in missionary again. I started fucking her with passion. Like she was my wife.
We fucked and she kissed me until she had and orgasm and I cum on her stomach.
The next morning. We got up and faced each other. Now sober I thought everyone would regret it.
But we all enjoyed it.
We went to dinner with them Wednesday night. Everything was good.
My wife said Rob had a lot of stamina and could really eat pussy but he wasnt very big.
My fantasy became reality fucking Sue.
My wife said Sue stopped taking birth control for medical reason .
