As luck would have it I received a call from my Doctors office, telling me to be at the hospital for a C-scan Thursday evening. I had been having a problem with my ribs for over a year and finally someone was going to look at it. The hospital is a busy place and they keep the Imaging Diagnostics clinic open 7 days a week trying to keep up. My appointment was for 8 PM which worked out well for me since I had to work that day and it was an hour travel each way.
Thursday came along and Cynthia my submissive girlfriend wanted to come along for the ride. We got there and went down to the clinic to register. The nurse took all the info, told me that we would be about half an hour late getting in because of an emergency due to a road accident. I shrugged and said no problem, understanding the situation.
The nurse took me over to the waiting change area and told us to have a seat and wait, and when ready she would inform us so I could change into the customary robe.
Looking around the seating area, we were isolated, although we could see the hallway if anyone walked by. The change rooms lined up beside us were nothing but small cubicles with a curtain. Inside there was a small locker and a chair.
I was watching the news when Cynthia gave me that look, the look that says she is bored and about to take us to a new adventure in our sex life.
"Master, I am bored." She stated. I simply smiled at her, saying nothing. Cynthia gave me a devilish grin, grabbed my hands saying " I always wanted to do something in these places but my ex was too prudish."
Well that is something Cynthia has never accused me of, and I let her lead me into the change room.
I allowed myself to be guided into sitting in the chair and Cyn just grabbed a couple of the gowns and kneeled before me. Before I could protest, she pushed me back further, unzipping me, and proceeded to feast on my semi hard cock.
Now if there is one thing this girl loves more than sucking cock, she loves to suck it from a soft state, letting her be totally responsible for making it hard. She said the feeling of power as it grows in her mouth is absolutely wild for a woman, so who was I to deny my slut some pleasure.
I settled in for some dangerous fun, letting her glide her wet tongue up and down the shaft, sticking it up under the foreskin and around the glans. Damn she was proficient and was not long before I was rigid.
Her one hand explored the large vein on the bottom side of the shaft, pulsing it, her other hand caressing by swollen balls. Before long her mouth slowly covered the head, caving in her beautiful cheeks to apply just the right amount of pressure, allowing some spit to run out the corners of her mouth for lubrication. Damn she is a great messy cocksucker, the best kind, getting lost in our pleasures.
