Carol started humping her hips, thrusting so that my fingers were buried deep inside of her and she started pinching her nipples.I pulled her close to...me, my cock between her ass cheeks, my fingers driving ever deeper into her cunt.I whispered hotly in her ear, "You're a dirty girl. You're my dirty girl."She groaned, "Ahhh fuck. Make me cum."My fingers plunged into her cunt, pistoning and groping. Carol started breathing heavily. She pushed back at me, trapping my cock between her ass. Anyway, his white teeth flashed as he gave me a knowing smile, a broad wink and the universal hand gesture for jacking-off. He was very handsome and I surprised myself by returning his smile and wink. About an hour passed, and then when I was dancing with John he managed to get his hand between our bodies, up my dress and onto my pussy. The shock of his fingers on my damp, throbbing clit made my legs buckle for a second. That seemed to settle it for him. He led me back to the table nodded to. They teased me together.Bucking and squirming on the examination table, I could not help but cry out in agony and pleasure.Just when he knew I was about to explode, the doctor finally removed his fingers from my gushing slippery cunt.He then asked me to roll over onto my hands and knees, so he could examine my rectum. Nurse Sharon pushed a pillow under my head and she rubbed my neck as I got into this new position. I could feel my wetness running all over my inner thighs; but the doctor. John pretended not to notice and still be asleep. She could see that he was trying not to smile. Julia licked at his nipple that was nearest her. John turned his head as he continued to pretend that he was sleeping. Julia grabbed his dick harder and stroked it quicker. She could see that John was still trying not to smile, but his legs began to move, and his dick began to harden. Julia leaned down and flicked her tongue at the head of John's hard cock. John flinched slightly and then Julia.
