"Heinlein was at its warmest during this season, so they both wore shorts, a tee-shirt, and flip-flops. With their pistols worn cross-draw fashion and...their shotguns in carriers on their backs, they looked like any other young couple out for a leisurely stroll. They visited a couple of small neighborhood markets and walked home, each carrying a bag of groceries.As they were crossing a street, a truck came running through a red light headed straight for them. Jim dropped the bag he was carrying. With the exception of our friends, Jack and Peggy, the other four couples are strangers, unknown to us before this night. Jack and I were buddies since grammar school and a short time ago he and his wife had introduced Evie and me to the art of swinging. This was the first time we had experienced it with more than just the four of us. I wasn't sure that Ev would go along with the idea. She had always been rather prudish regarding sex and the first time, it took a bit of trickery to get her to. Then I straddled him and slid my pussy down his cock. I shuddered as I felt his thickness just fill me. Omigod, I just wanted to ride this thing forever. I was getting bimboey already, but I couldn’t help it. Every nerve was on fire and dipped in pleasure at the same time, and I couldn’t control my moans. His hands held my hips in place as he grinded into me, and my boobs jiggled as I shuddered from helpless pleasure. Then he bounced me on his cock and I screamed like a slut in heat. He was. A few years ago, this mistake happened to me the first and last time. My friend Debora had her place for two weeks for herself, because her parents went on vacation. Her little brother was sleeping at his oncle's place. So in those two weeks we pretty much had non-stop party at her place. She, and my other friend Vera, were always the only girls, and all the other partymembers were male. They even got alcohol for us and some even got us some we-ed, so we can get high. I never smoked we-ed back.
