The week went so slowly! It was terrible and made bearable only by the constant thrusting and buzzing of my vibe. I wanted to feel the old man's hands on me again, to taste him in my mouth, to feel him cum and taste that delicious salty liquid. I lost count of the orgasms I had that week all the while imagining what he would do to me at my next appointment.
I was nervous when I entered the doctor's office on that Friday afternoon, I planned to pretend to drink the drink again, pretend to be unconscious of his molesting me and then surprise him when he was most vulnerable 'waking up' just when he had put his penis in my mouth.
But now I was wondering how he would react, would he be angry? I was sure he wouldn't because I would keep on sucking him and he would know that I wanted it, wanted his dirty old penis in my mouth.
I disposed of the drink as last time, remembering to wipe my mouth and play along. I lay back as I did every week, but this week I knew what was coming and I yearned for that salty taste in my mouth. The coldness of the bottle once more teased the lips of my vagina before being firmly pushed up inside me, my knickers around my ankles and my legs splayed for the dirty old doctor.
He unzipped and I could smell him again, so dirty and so sexy. My mouth watered in anticipation as he rubbed the fleshy tip around my mouth and then pushed in. It was now or never, I sucked his penis into my mouth and opening my eyes found him staring directly at me with a look of animal lust on his fat old face.
"You are awake?"
I smiled as well as I could around his penis and continued to suckle him feeling him grow hard in my mouth.
"How wonderful," he gasped.
I frowned as he withdrew from my mouth.
"Please I want to suck your penis," I murmured reaching for him.
"Yes my dear, but another time. Now we must move to the next stage of your treatment," he breathed as he lowered his trousers and kicked them off. "And please do not say penis, say cock if you want my spunk. You will need to learn to speak like a whore if I am to treat you like one." "Please doctor I want your... cock...please," I begged.
The old man chuckled, "Very good my dear, but first we will learn something else."
For a fat man he was quite agile and was soon kneeling between my legs. My breathing quickened as I felt his fingers probe my vagina, "Now I will put my cock in your cunt and fuck you Sarah, but first you must beg me for it, beg me like a slut."
I was on the verge of cumming there and then as I stuttered the words he wanted to hear, "P...please doctor, please fuck me, please put your c...cock in my cunt."
I gasped as he thrust his old cock into me in one smooth motion. It felt different to my vibe, not as big but more pleasurable. It was warm, soft and hard all at the same time. His enormous belly came to rest on my chest, pressing me into the examining table and I automatically wrapped my legs around his back as he began to thrust his old cock in and out of my vagi...cunt.
I pulled him face towards mine and we kissed passionately, he tasted of cigars and his chin was rough and prickly against the soft skin of my face.
