All the patients had gone to bed and chee had said her good nights so I settled down in my shorts and shirt put the TV on to watch a video, porn of co...rse , I was watching quietly and I was getting quite turned on by it I put my hand down my shorts and felt my cock it was rock hard and I be gang stroking it it wasn't long before it popped out of my shorts and there I was engrossed playing with my dick watching the TV . Then suddenly I heard a noise at the door it is kept open so I can hear. I was instantly even more uncomfortable as my cock sprang back into life inside my tight jeans. Over the next 10 minutes or so she crossed and uncrossed her legs 5 or 6 times each time giving me a special view of the loose knickers. I was soon dangerously close to spontaneously cum-busting in my pants. Eventually she got up to leave and as Mum walked her to the door and Dad went off to the loo I made my escape and whipped my cock out the second I made it to my room. It only took a few tugs and. I let her stay as she was for a while, taking a few moments to rearrange some of my tools on their rack alongside one wall of the cellar. Eventually I turned to Nicola."I should explain," I said, "that I consider you to be an intelligent woman. It is just that you have not yet focussed that intelligence as your husband needs and as a result it has been more of a problem than a benefit to you – at least as far as your married life is concerned. Generally speaking I will not tell you what you. .come taste me...lick my wet pussy...mmm, I want to feel you lick me". My cock pulsed in my hand at the sound of her erotic pleading, then I grinned and teased, "Do you have an appointment?" She giggled then playfully pouted, "Ohh pleeease Mr. Cockenballs, I neeed an appointment with you...don't let me play all by myself". The power of her erotic persuasion was irresistible. I could visualize the wicked grin and seductive gleam in her eyes, knowing that she had me. I excitedly told her I was on.
