This happened just last week. I went to the doctors to get a physical exam done so I can finish my application procedures for NYSU next fall. After all the normal procedures, a brunette nurse came in to draw my blood. She told me to lie down and had my arm to my side, with my palm facing up. When she had tied the rubber band around my arm, she applied alcohol to my forearm near the joint.
For some strange reason, she took about a full minute tapping and examining the area to which she applied alcohol. I knew she was just checking for my blood vessel, but I thought it was taking a bit longer than usual. Then, all of a sudden, I felt something soft on my palm. Not realising what it was, I glanced down and was surprised to find that the nurses right breast was right on top of my hand as she leaned over.
As soon as I realised this, I felt my penis being engorged with blood. As I made a tent in my trousers, I tried to fidget around to cover it up. But the nurse had noticed this and smiled. She said not a word, but she continued to examine my forearm, pressing her breast harder into my hand. I thought I was about to explode a load right then and there.
Though at first I thought that the nurse would get mad, since she wasn't showing any signs, I thought I might explore some more. Carefully watching her face for expressions, I gently squeezed her breast. Surprisingly, she didn't say anything but remained calm. All the more she stayed that way, I increased the pace of my fondling. This went on for about two full minutes before the nurse was done drawing my blood. As if nothing had happened, the nurse headed out of the exam room.
As soon as I was done, I headed straight for the bathroom and shot a huge load of cum. This was an experience I'll never forget!
