The time finally came for a full health check, which included a prostate exam this time round... After all the other basic checks, it was time to perform the physical which would include the dreaded finger... As it happens, the doctor was a relatively good looking middle aged man, who made the whole process seem so easy and routine, which helped relax me a lot... He asked me to lie down on the bed in his rooms whilst he was performing his checks. As the time came, he asked me to roll onto my side, raise my knees and also lower my underpants. He was jovial and making jokes about how this is always the dreaded part, but not such a bad experience for most. I kind of laughed as I got into position. He kept making small talk, as he put on a glove and lubed his finger. He then spread my cheeks and slowly his finger entered my hole. His finger probed around checking for my prostate and as he found it he started stroking it explaining to me how it was a good size, and that he’s sure that I’ve had my prostate milked before and experienced that type of orgasm. I said that I actually hadn’t, and that I would try and get the wife to do it, as it felt quite good. I was wondering how long this would carry on for, as his finger was still probing and playing around for a bit longer than I expected. I was actually starting to get hard, which was a bit of an involuntary reaction (at first). He then asked me to roll over onto my back so he could conclude the examination. As I rolled over, my now fully erect cock popped up, and I caught a smile on his face. He raised my knees up again, as his finger went back into my hole, and he moved my ball sack around feeling for “lumps” and giving me the all clear. Whilst his finger was still probing, he mentioned that I had a lovely looking cock, which took me by surprise, and I feebly said thanks. By this stage I realized that this wasn’t a usual check, and it was up to me to call it to and end, or to let it run it’s course. I decided that the latter would be the more interesting of the two... I leant my head to the right, to notice that his pants, now right next to my face, had a bulge in the front. Clearly this had him all excited too. I decided that I would finally see what it would be like to have a cock in my mouth, and without staying anything, I unzipped his pants and pulled them down and his cock popped out through from under his shirt. He clearly didn’t have a problem with this, as he kept playing with my prostate and my cock... and with that, I leant a bit close, and with my right hand pulled him closer to my face, and slowly took his cock into my mouth... This was a complete first for me, and felt absolutely amazing at the same time (other than being nervous as hell)! His hips started gyrating front and back as he slowly started to fuck my face... with his large cut cock sliding into and out of my warm wet mouth. I was so excited, that he made me cum, spraying my cum all up the from of my shirt and stomach, and he milked me dry... the most amazingly and different feeling experience I’ve had! At the same time, once I stopped my spasms... I kept sucking and licking his cock, until he started tensing and I let him empty his load into my mouth... which was luckily for me I guess, not a massive load, as it was the first time that I had ever done this, let alone get cum in my mouth! He gave me some tissue paper as I wiped my mouth and chin, and he cleaned up his hands. After cleaning up, I rather spastically put my clothes back on, and awkwardly said thank you a but as I almost rushed out to pay and leave... He smiled and waved as I left his suite, and I am sure his secretary must have known what had happened, unless it’s just my guilty conscience... but man, that was actually quite the intense but fun exam in the end! I’m now wondering when and how the next session would go...
