I made a mental note to ask Paula later, as she was clearly occupied. "She is ready for a DP, aren't you Paula?" Paula only nodded her reply. Because ... had been behind her last time we had doubled penetrated her, I quickly rolled onto my back and pulled my wife on top of me. She quickly guided my cock inside her pussy, and a brief moment later, I could feel John enter her ass through the thin membrane between us. The sensation was electric! With every thrust, our cocks bumped and jostled. I promise that this willbe one of the most rewarding experiences of your life." She led him toa different door than her office, a door to a small medical clinic.Tom felt nervous as he looked around. There were several examining roomsand a lab. The nurses looked up as he came in, and smiled warmly. Theyalso all looked pregnant, like the girls in the outer office. "So nowwhat? Alien ray machines and probes? Tissue samples?" Tom askedcautiously."Not quite," Rachel laughed as she led him into. Then I felt it another cock this time with a condom on was trying to enter me, I forgot about the other men in my Ecstasy, It slipped inside me and started to fuck me, I looked round he was a little older in his 50's smartly dressed. His cock moved inside me and I felt myself tighten round him, he mumbled "this OK?" I nodded. His hips were slapping against my ass, I started to moan with each thrust, then I felt the spit hit my asshole and then his middle finger enter my ass, "Still OK" he asked. She was a very sexually active girl in high school losing her virginity at the age of 14. She had sex with numerous guys before meeting me. She was somewhat thinner back then to and very attractive. I asked her why she wouldn't consider swinging she said she was to fat for that and I was all she needed. This was always the same answer and she tired of me asking, and sex never was getting better. During sex I would sometimes fantasize out loud how I was another guy while we had sex and it.
