Recently I made an appointment with my GP to check myself out. I had started going out with a girl who I really liked and thought it would be a good idea to get everything down there checked before we did the horizontal dance. I sat in the waiting room incredibly nervous. Dr Harper came out and called my name, I said yes, he smiled and ushered me into his office. I would describe Dr Harper as a tall, in his mid 50’s, had white hair, with a slight stuble. I am 20 years old, slim, average height. We began discussing why I was here and he did well to reassure me that I had done the right thing and that it was better safe than sorry. He told me to drop my trousers and pants and lie down on the examining table. I was sweating a bit, had gone an incredible shade of red and was breathing quite heavily. Dr Harper stood over me and flicked a light on and moved it over my crotch area. He put on a pair of latex gloves and started feeling my testicles. At first I just lay there, completely still, worrying about what if he found a lump or something. He continued to feel them for what seemed like ages. I thought he was being really thorough! I don’t know what happened next, but all of a sudden the thought of this middle age man touching my testicles started to get me a little excited! He was feeling them in such a way that it actually felt kind of good. I had never even thought of being with another man before but at that moment it really started to turn me on. I began to panic as I felt my cock beginning to get hard! I was so embarrassed and began to apologise to him. He smiled and said “Don’t worry, it happens to a lot of my patience.” My cock was now fully erect as it rested on my belly. Dr Harper continued to feel my genitals and was asking whether certain things hurt. I remember innocently replying “err no, it feels good.” I then realised at what I said and tried to back pedal. Dr Harper smiled and said he knew what I meant. He then grabbed my erect penis and pulled back the skin. He explained that he needed to look under the head of the penis. I just lay there with my eyes close. Partly due to embarrassment and partly because it felt so good. His hands were now wrapped around my 20 year old cock, and I was just desperate for him to wank me off. I was urging him in my mind to slowly start rubbing my shaft. My cock was still rock hard as he carefully looked closely at my purple helmet. I felt a little bit of pre-cum dribble out of my hole. I was that excited! Dr Harper then said that he was going to need a sperm sample to check I don’t have any STI’s. I thought that was odd because I’m sure all you needed to do was pee in a cup. I agreed and thought he was going to leave me to jerk off so I could provide with a sample. He smiled and asked whether I needed some help with the sample. At this point his hand was still wrapped tightly around my cock. I smiled and said yes please. He began to jerk me off! I couldn’t believe what was happening. I just lay there and enjoyed the site of my GP wanking my cock off. It felt amazing and the fact that a middle age man was doing it was such a turn on. I felt the point of no return coming. I lay back on the table, closed my eyes and enjoyed the last few tugs before my hot stick load shot up in the air and onto my belly. Dr Harper continued to tug as I ejaculated. He then groped my balls and gave them a little massage as my cock began to slowly return to its floppy state. I felt so exhausted! I sat up and surveyed the scene of the crime. Cum was everywhere, all over my genitals and Dr Harpers hands. He was massaging it into my legs and crotch area. It felt amazing and was so sexy. “Everything feels fine Mr Jones.” He said. “However I will book you in for a prostate check next week just to make sure.” I left the office with a big smile on my face. For the next week I furiously masturbated to the thought of what happened. I don’t even give a shit about my new girlfriend. Can’t wait for that prostate check!
