i (M) have known a couple for close to 7 years. It started as MFM which was an amazing experience with these two. She would turn into such the naughty nymph and her hub enjoyed watching her enjoy the touch of another man. After a couple of years he began a new job which kept him out of town 7-8 weeks at a time. Her pent up desires were being unmet and he gave her the OK to reach out to me and meet solo. Usually it was lunch with drinks then escape to a hotel room for the afternoon. One time we went to dinner and when we left I did not tell her where I was taking her. We pulled up to a swingers club in Nashville and she did not hesitate. It was a Thursday night so a little slow but people there. She had never been so we took our time, danced, drank and wandered the club checking the scene and the theme rooms. Finally she was so overwhelmed she pulled me into a small room that was still open and no door. Now she loves cock and when she starts she is insatiable. We are doing our thing when another couple came in and sat across from us in a love seat. The wife on her husband's lap. They just watched. I could see they were whispering but they never took their eyes off of us. I finally sat on the couch and Leann lowered herself onto me. Leann fucks so hard and cums so hard when she is on top. She loves my cock and each time she lowers herself onto me she lets out a guttural moan. I could see over her shoulder the couple and when she lowered herself, enjoying the thickness of my cock, I could see the wife mouth "oh my god". They enjoyed the view just staring. After a couple of minutes, I motion them to come over and sit next to us. They were frozen not knowing what to do. Finally I said, "come sit on either side of us, you will have a better view" . They looked at each other and slowly came over. Each sitting on either side of us on the sofa. Leann was in full stride, grinding and moaning. I could see they were just staring at her plunging on my cock, her face in ecstasy. I then grabbed each of their hands and brought them on each of Leann's breasts. She has perfect full B cups. This surprised Leann as her eyes had been closed but that triggered her to a violent orgasm. The wife of the couple I could hear breathing is shortened breaths. Now Leann never stops when she cums and continued to roll from orgasm to orgasm. I finally said out loud, "do you want to see her suck my cock?" The husband quickly said yes. I told Leann "They want to see you finish me with your mouth". Leann slowly got off and onto her knees. She looked at the husband, then the wife and said "Like this?". The two of them could not take their eyes off of Leann. I would look out of the corner of my eye and see them fixated on watching her work my cock with her mouth and hands. At one point her hub said "He is big". I turned to the wife and asked her "Am I?". She just nodded, not taking her eyes off of Leann. As I began to build up I grabbed the wife's thigh and squeezed as the roll of an orgasm began to take me. I erupted in Leann's mouth and although not her favorite thing to do she swallowed every bit of me. We were all panting as she collapsed in my lap. The wife of the man said "wow, thank you" The two of them got up and I could hear her saw as they walked away "That was hot" Since then, I will whisper in Leann's ear, "remember that time the couple watched us fuck?" That is all I have to do to get her wet at lunch. She is squirming from then until we fuck. I have since taken her back to that club and we have enjoyed more fun!
