I have a female co-worker that I have known for many years, we will call her Sue. Sue is married to Mark and they live a mile from the office and Sue goes home often to have lunch with Mark a few days a week. One day Sue asked me if I was busy for lunch' and if I would like to have lunch with Mark and her. They were getting a Pizza and had plenty of food.
We had lunch and were talking around the table and Sue said she had to go take care of the dogs and would be back in a few minutes. Mark and I started talking and in a few minutes, he said he had something he wanted to ask me, and I said what is it.
He said that Sue had this fantasy for a long time and she would like to see Mark masturbate together with another man. Sue was embarrassed to ask so Mark said he would ask. Since they both knew me well, as uncomfortaable as it was to ask they felt I was the best person to ask.
Just then Sue came back in the room and looked at Mark and said did you ask him and Mark said yes. Sue looked at me sheepishly and said she was embarrassed but excited and what did I think of the idea. I said I think it could work but I had some fantasies that needed to be addressed also if we were to move forward. Mark said ok what are they? I said they are really more directed at Sue and not you so let me tell you what I would like to see happen. Sue said I am all ears.
First I want all three of us to be totally naked when we do this and I need Sue to have her legs wide open as I need to see Sue's cunt for inspiration. Second when I am erect I want to have Sue squeeze my balls as I masturbate. Sue looked surprised but eager, Mark looked apprehensive. I said think about it, it is getting late and Sue and I need to get back to the office.
The next day Sue said would I like to have lunch again today and I said sure. We left about noon and went to her home and went into the family room. She said she and Mark discussed my ideas last night and decided to try it. Just then Mark walked into the room completely naked and asked me if I was ready for some fun. Sue and I got naked and Sue sat on the sofa with her legs spread wide apart and asked is this what I had in mind and I said works for me. Mark and I stood in front of her and started stroking. As we stroked Sue put her hands on either side of her cunt and spread it wide. It was huge and very deep a really beautiful sight.
Sue then said whenever I am ready she will squeeze my balls, and I said ready when you are. She then came over knelt in front of me and took my scrotum in her hand. She was squeezing and pulling at my balls madly and I said gasping, I am going to cum soon, she said ready when you are and kept squeezing. Mark moved over next to me and we were both stroking madly and looking down at Sue wildly pulling my balls. It didn't take long before Mark and I both came all over Sue's face. Sue stopped squeezing and smiled and said that was even better than she thought it would be as she licked as much cum off her face as possible.
We then got dressed and went back to the office satisfied with our mutual session.
