I’m Andy and I’m pretty fit as I go to the gym regularly and also play football twice a week. I’m twenty-five and despite my exercise, I was found to have high blood pressure a couple of years ago. It doesn’t affect me too much but I have to have regular check-ups at the local health centre.

I sat in the waiting area for ten minutes and then I was called in to see Nurse Claire, in room six. I didn’t recognise the name and when I saw her I was stunned. Claire was a beautiful blond. She was slim and she had great breasts, which were pushing through her part open uniform, and her bare arms and long legs were nicely tanned. 

She was so sexy, I was struggling to pay attention to her questions and I had to ask her to repeat a few. She giggled sexily and told me to relax. She explained that she was going to take my blood pressure and asked me to remove my shirt, as the sleeves were tight. She seemed to like what she saw. My blood pressure reading was a bit high, not surprising, so she said she’d do it again. She checked my pulse and listened to my heart, which was apparently ok. 

My second blood pressure check was good. Then she became very serious and rather nervous, as she started to talk about erectile dysfunction. She explained it was a common issue with high blood pressure. I went scarlet and mumbled it wasn’t an issue. I think she took my embarrassment to mean I had a problem. 

She moved closer and I struggled to breathe normally, as I was now looking directly at her breasts and her nipples were pushing hard against her bra. She told me that all the standard blood pressure tests were done for this visit, but there was a new test that they were performing. She wanted to know if I was willing to take part in the trial. I’d have said yes to anything, and I nodded. She asked if I would like her to explain about the trial, and she carried on when I mumbled yes.

She was even more nervous talking this through but pulled herself together professionally. She explained that the new test was to evaluate any signs of erectile dysfunction. She cleared her throat before explaining it required her to stroke my penis and scrotum to time how long I took to become erect, if at all, and how long the erection lasted.

I told her, "I'm happy, I mean, willing to take part in the trial." I couldn’t believe I was being offered this. 

Again, she checked if I was still prepared to take part now that I knew what was involved. I confirmed I was OK with this. In fact, I couldn’t believe my luck; I was going to be stroked by this beauty. She asked me to go behind the screen, get totally undressed and then put on the short T-shirt provided.

By the time I said I was ready my cock was already growing at the thought of what was to come. She pulled back the screen and smiled as she sat facing me. She asked me to step forward and to stand closer, between her parted legs, which meant my cock was just inches from her face. She had a plastic ruler and measured my cock. My flaccid cock was not much to talk about but under these circumstances measured a reasonable four inches. She picked up a stop watch and then made a quick note on her pad. She apologised in advance that her hands might be a bit cold and then she stroked my cock, slowly and gently all the way along the shaft and up to the head, and my cock responded quickly. 

Her fingers rested on the glans as she explained that all seemed well but the trial required her to continue, whether the penis responded or not, until the end of the trial. It was obvious from her breathing and her manner that she was struggling to remain professional. She gave a little moan before apologising that this was her first experience of this test. She told me she was a little warm and undid the two top buttons on her uniform, leaving little to my imagination. 

She pulled back my foreskin gently before her fingers travelled along and then around my balls. My cock was now throbbing and becoming very hard. Her fingers never stopped and now she was rubbing precum around the head, sending electric pulses through my erection. She checked her stop watch and then put her fingers around the shaft and squeezed. She explained this was to allow her to evaluate the state of my erection. 

It was rock hard and she smiled at me and gave a little grunt before continuing. She was panting and she undid another two buttons of her uniform. Then she took my hand and slid it inside her bra on to her right breast. I stroked her breast and felt her nipples harden. She picked up the plastic ruler and measured again. Just under seven inches and, checking the time, she made a note on her pad.

By now she was breathing harder and I could tell she was aroused. Without a word, she got up and locked her door, then returned. Standing in front of me, she removed her uniform, her bra and her panties. My cock couldn’t get any harder. She took me over to the examination bed and laid me down on my back before climbing onto it, and on top of me, before lowering herself onto my throbbing erection. She bent over towards me so that her boobs were just by my face. I reached out and stroked them, feeling her hard nipples, and she groaned. 

Now she began to lift herself along my cock until I nearly came out but she expertly lowered herself until I was deep inside and then back up, gripping my glans with her vag before pushing down again. Moments later we both came and had to stifle our cries and she collapsed on top of me. We lay like this for a few minutes, then she climbed off me to fetch some tissue. I watched in awe as she bent over to pick up a tissue and I admired her most beautiful arse and shaven slit. She seemed to stay like that for a long time and my cock was responding again. After cleaning me up she collected her stop watch, held my cock round the shaft and squeezed before making a note on her pad. 

I enjoyed watching her get dressed until those beautiful breasts were fully encased in her bra again. She took one more check on my cock before suggesting that she wanted to know if this was a one-off, or did I usually have a problem. She booked me in for another appointment in three weeks' time, kissed the head of my cock and told me to get dressed.

This was one NHS appointment that I would not be missing!
