They were your typical, married middle-aged midwestern couple, except for one twist - they were swingers. I was a 20-something guy at the time and fou...d this out after getting to knowing them awhile because they told me they swing for fun, and of course looking back at the time after they told me, it all made sense to me because Lisa was always flitering back and forth with me and Mike never really minded. It actually turned him on that guys wanted his wife - and even more amazing was that he. I now had my hands on her slim waist pounding like crazy at her asshole and squeezing her soft round cheeks to increase the pleasure around my wet shaft as it slipped between them, and all the while my balls were slapping against her wet hot cum dripping pussy, and after just a few more thrusts I knew I couldn't last much longer."I'm going to cum! I'm going to cum!" I groaned again more urgently."Yes! Yes! Yes! Do it! do it!" cried Mrs Jones.I thrust into her again and then again and then again. Cassie’s brother had a part in my downfall, and he slammed an iron fist into my ribs more than once. I don’t know who jumped on my leg after I collapsed to the ground. The pain was too much, and everything faded to black. I’m lucky to be alive.Eight weeks have passed since I received the pounding of a lifetime. Two cracked ribs, a ruptured spleen, and a serious concussion. I spent three days in an induced coma, and I had surgery to repair a fractured patella. The brace is off, and I’m slowly. I shut the computer and went about my business for the day. The strange thing was, I couldn't get the thoughts of those awful stories out of my mind. I work in the office of a small engineering company, and have lots of men coming in for one thing and another, most of them business like, but there's always the few that you feel are ogling your breasts, or legs, or backside. I usually take this sort of thing as a compliment, but this day I kept wondering if they were really thinking of torturing.
