A Step Mother's Sin - Ch. 7 - Horseback ridin

... an experiment. The balls shifted and vibrated causing a weird sensation against my g-spot. "Well does it feel good?" "It is not unpleasant. I guess it feels kind of nice. I doubt I could climax like this, but it is stimulating my g-spot.' I arched my hips slightly, making the balls collide and vibrate. "Yeah baby, they feel good," I finally admitted. I arched my hips again, "Robert, every time I move they click together and that causes them to vibrate a bit. I also have to clench my vagina to keep them from falling out of me. So they keep me very aware of my vagina." I contracted my vagina again. I was beginning to enjoy the constant sensations inside me. "Well Cindy, finish your bl**dy Mary. We have an appointment at noon." Robert had a sly grin. I knew he was up to something. Or should I say, something else. "What kind of appointment? What are you up to?" I had learned my young lover was usually up to something. And he was certainly creative. "We are going horse back riding. There is a stable that rents horses about ten miles from here." "Oh my god, Robert, I can't go horseback riding with these things inside me!" "Sure you can. I promise, you will enjoy it." "Robert, I haven't ridden a horse in years."

You are by far, the best lover I have ever had." Every bump, shimmy and shake of the Mustang convertibleon our drive to the stables caused thespheresto click together and vibrate against my g-spot. "Robert, these damn things are starting to get to me. Why don't we skip the horseback riding and go back the room. Oh god, I need for you to fuck me now." I reached over and caressed his penis through his jeans. I felt it throb under my touch. "Please, baby, take me to the room and fuck me good. Please." Robert took my hand and removed it from his penis and said, "Mom, I mean Cindy, let me decide when and where I fuck you this weekend." I simply moaned as I rocked my hips in frustration. I was just on theedge, but I could not get there. Robert obviously enjoyed watching me squirm in the car seat next to him, humping my hips upwardagainst the air trying to make the balls vibrate against me. I placed both handsbetween my legs, and started to rub my clitoristhrough my jeans. Robert reached over,grabbed my hands and pulled them away frommycrotch. "No ma'am. You ...
