One day my wife Sharon announced that her friend Darlene, and Darlene's husband Bob, were coming to visit us the next weekend. Sharon and Darlene had been roommates in college, and I had met Darlene at our wedding a couple of years ago. She was from the Midwest and had a cute cowgirl accent and a very outgoing approach to life. I had thought at the time that she would be pretty hot in the sack.
Bob and Darlene arrived that Friday afternoon. Bob seemed like a regular guy and we hit it off pretty well. Darlene looked just as hot as I had remembered her.
Sharon had made dinner reservations for us at a local restaurant, and so we all went upstairs to change. When I saw the dress that Darlene was almost wearing my eyes nearly popped out. She was showing a lot of cleavage, and a large slit in one side ran up almost to her hips. I tried not to stare at her during the evening, but it was impossible to keep my eyes off her.
Later that evening as we were getting ready to go to bed, Sharon suddenly turned to me and yelled 'You bastard! You spent the whole evening looking at Darlene and ignoring me!'
"No I didn't," I protested weakly.
"I suppose that you want to fuck her now too!" she shouted. Then she ran over and tried to hit me, but I grabbed her arms and pinned them behind her back.
The door opened and Bob and Darlene came in. Darlene came over to Sharon and took her hand. "It's all right, sweetie," she said. Sharon put her arms around Darlene. "He's such a bastard!" she sobbed.
Darlene stroked Sharon's hair. "You're too hard on him," she said. "You know what men are like. And Bob couldn't take his eyes of you all night."
"Really?" sniffled Sharon, but she seemed to brighten up a little..
Then something totally unexpected happened. Darlene kissed Sharon on the lips. Sharon kissed back. The kiss lasted for a couple of minutes. Then I remembered that they had been roommates in college. Very close roommates apparently!
Darlene broke off the kiss, and then said, "So the way I see it, we can all keep fighting and maybe have some very ordinary sex. Or we can swap partners and see what happens."
Darlene walked over to me, put her arms around my neck, and kissed me. The shocked look on Sharon's face soon turned into a sexy smile. She walked over to Bob, kissed him, and then pulled him down onto the bed.
