My Best friend fucks me

So my mate John and I were best friends for over 15 years. We have know each other forever. I was his best man when he married Mandy, and she became a great friend too, there was never any thought of sex between us, as they were both straight and no one knew I was bi. I had work hard to keep that part of me discreet, by only ever meeting married men or men from out of town. I had played with a hand full of couples.

It was uncommon for us to stay over at each other’s house if we were out drinking.
This Friday night we had meet in town and we’re having a great night drinking and talking. Around 11 Mandy told me we were all going back to their place to keep drinking. There was about 10 of us and the night just kept on going. Around 3 am I came back from the bathroom and all the people were gone. It was John and Mandy, they were both sitting at the table looking at Mandy’s phone. She had a huge smile on her face and he looked excited.
I asked what was up.

Fucking my mates wife in the arse!

So about 15 years ago. I’m at a bar in town having some drinks with friends and my mates wife turns up. Tells us all that he is out of two for two weeks.

After a couple more hours of drinking and dancing. She starts to dirty dance with me a is rubbing herself against my crutch, I can feel myself getting hard and I know she can feel it. But I’m thinking there’s nothing going to happen. After all it’s my mates wife and my other friends are here.

As the night goes on my friends start to leave. Then there is just us two.

She tells me that we are going back to her place and we are going to fuck!

So I just go with it. We are all over each other as soon as we get in the front door. We make it to the bedroom but not the bed. She’s taken my cock out and is giving me the best BJ I have ever had! Now I have a average length cock but it’s fat and the head can swell to about 2” in diameter with the right person. And she was that person that night.
