I was watching my wife Lynn working on Al, and the distraction somewhat hampered my reactions to Barbara's ministrations on my dick. Surprisingly, Al's member suddenly went very stiff, his eyes opened wide and he began spurting sperm into my wife's mouth. As I watched, I couldn't believe her reaction. Lynn had never given me oral sex, and as far as I knew this was the first time that she took a cock into her mouth. Al's cock erupted into a sperm fountain. Lynn, aside from a few dribbles from the corners of her mouth, swallowed it all. It went "down the hatch" into my wife's gullet. I was amazed that she didn't gag or spit it out. She seemed to really enjoy the fact she had made this man, who she didn't even like, come in her mouth right in front of me. She turned and looked at me with a sly grin on her face.
Meanwhile, Barbara continued working on me. After watching Lynn's performance, my own slacked a bit from the shock. I then asked Barbara if she would like me to go down on her. She eagerly agreed, so I laid her on the bed. I draped her legs over my shoulders, bent down and began to lick her from her stomach down to her crotch, then up again, then down again. At each down-stroke I paused and caressed her clit and labia with my tongue, then up to her neck and belly, then down again. She began to squirm and moan.
Lynn watched this performance, then decided to join in. I now began licking and sucking both women alternately and watched them become excited. I think Barbara experienced an orgasm as her face contorted, her hands tightened around me, and she let out what sounded like a repressed long groan.
I then began concentrating on my own wife. Her reactions were not as severe or fast as Barbara's, but she began, slowly at first, wriggling her hips and letting out little noises. I decided at that point to focus on Barbara. I again draped Barbara's legs over my shoulder, grasped her hips in my hands, and entered her vagina. I pumped her harder and harder, faster and faster. She responded majestically, grasping my shoulders and moving her hips up and down to my own rhythm. Lynn watched all this going on, and I think it was getting her hot but she said nothing; just watched Barbara and I in our sexual machinations. Finally, Lynn spoke: "Honey, I would like to suck you as you eat Barbara ." Barbara came down from the sexual high she had been on due to my pause in action, and said she would like that. So I knelt on the floor, turned myself a half turn to give my wife access, and lifted Barbara's hips up so I could eat her pussy. Lynn knelt to left, tucked her head under my crotch, and began giving me a phenomenal blowjob.
The three of us continued pleasuring each other for about 20 minutes in this manner as I became more excited. I didn't want to cum until I could fill Barbara's womb with my sperm so paused my wife and began fucking Barbara. To make a long story short, after stroking Barbara's cunt for a reasonable period of time I came, strong, into her.
Al was still laying on his bed, drunk and unknowing of what had been transpiring around him. I decided it was time for us to return home. Lynn and I each dressed and left Al and Barbara. Barbara gave us each a goodbye kiss; mine deeper and lasting quite a bit longer than Lynn's.
After we returned home, we spoke about what had just happened. Lynn said "At first I did what I did to get even with your dalliance of years ago, but as I sucked Al's dick, I got a really strong sexual high. I enjoyed giving him a blowjob and I loved swallowing his cum." I told her that I, too, got very excited watching her do it, and was very impressed with her technique. I wanted her to do that for me. By now, about 45 minutes had passed between our activities at Al and Barbara's. I had recovered enough to sustain another hard-on, so Lynn began sucking me. Her skill was incredible! She was much better than the supposedly more-experienced Barbara and it didn't take long for her to stimulate me to an ejaculation.
As I came, she again swallowed every drop of my sperm. She now had two men's essences in her belly. She smiled at me and asked "Are you surprised at my skill of giving blowjobs?" I said I was, very much so, since she had never wanted to give me oral sex before. She then told me "Do you remember 10 years ago when you had sex with your co-worker Susan? Well I called her husband and asked if he knew what the 2 of you had been doing. Al said he had flat-out asked Susan if she had been having sex with me, and she confessed about her giving me oral sex. Lynn said "To get even, we decided to have our own affair. Al taught me Susan's techniques. It began as revenge sex, but I found I enjoyed it as well, so we continued to meet occasionally over the next few years, giving each other oral sex as well as trying multiple positions of copulation." From that moment on, I realized that for over 20 years I had misjudged my own wife's desires and abilities. I took maximum advantage of my new knowledge, and we didn't neglect Al and Barbara, either.
