Unobtrusively reaching under the edge of the table, Robbie turned a small dial a quarter turn, listening for the whisper quiet sound that confirmed th... mechanism had been activated. This was a series of very thin metal rollers embedded into the padding in the area just underneath Trey's chest. These rollers were linked in a belted assembly that when activated caused them to turn while being pulled slightly from side to side. Charged with a very low voltage electric current, the overall effect. Stifling a nervous giggle, I reminded myself that I was barely recognizable myself. I wasn’t Shannon Spencer, all-American high school girl and secret lesbian whose heart was pounding like a jack hammer as the door closed behind me. Today, I was Shannon Spencer, Mrs. Vandermeer’s teenage whore. I kind of liked the sound of it, enough that I wanted to share.“Your whore,” I let out in a rush, swallowing hard as she removed her glasses and turned her steely blue gaze on me, one eyebrow raised. "Here, let me get a little more comfortable." I wiggled my ass back and forward causing his dick to move around inside me more. As I was riding my son's dick, I looked over at my husband. Mike was still pushing his dick in me as hard as he could. "If only he knew. Here I am naked, fucking my son with my husband right next to me. "How soon do you think we can visit Mike after he settles in his dorm?" Well with my work load it's going to be hard to get away, but it's not that long of a drive, you. And remembered that he loved to have his balls and taint licked while he finishes and blows his nut all over my face. I wanted to make this happen again, and by the hungry look in his eyes I could tell that he fetl the same. I make my way to the counter with my loot and make my purchases, a cute purple set and a big bottle of astroglide. I prefer astroglide over the usual anal lubes as they usually have a desensitizing creme and I would prefer to feel every inch of whatever is fucking my ass.
