I had won the national lottery a few months earlier and had just bought my dream house – indoor heated pool, large sauna, majestic view of the ocean... – perfect. I was trying out the sauna for the first time and was lost in the moment when I heard voices which snapped my attention back to the real world. Two of my step daughters friends turned up uninvited to check out the new house and had let themselves in through the pool door. I had nothing but a towel around me to cover me so checked that it. Sharon looked like a true slut now all to be used later. I took her into the garden where the machine was set up and strapped her onto the machine, she was face down as she slide back onto the insertion pole and eased it into her cunt. I adjusted the head restraint to hold her both in place and available for use at both ends.The men started arriving, and each one was walked through to the room and shown Sharon displayed impaled on her pole, when all the men arrived, which took about twenty. You know as well as I that there are numerous other things that could happen even if you didn't leave me," I responded."Like what," she queried?"Colleen, why are you playing games? You know as well as I do what can happen. You could have an affair, for one thing. Some of our divorced friends who had affairs convinced themselves that it would actually help their marriage. What a crock of crap that kind of thinking proved to be. I don't buy it and I could never accept it if you chose to go that. Not sure what to do but wanting to fuck her I got on the floor and stuck one finger inside her pussy. She looked up at me and smiled real big. Then she leaned over and undid my pants. She had take off my shoes, then my pants and shirt. Now I was just as naked as she was. She pulled me on top of her and guided my super hard cock into her soft wet pussy. I slid easily into her. "Now just push in and pull back. That's it, a little more force." Tina said. Her pussy felt amazing, even better than I.
