I was trying hard not to look at his big dick but he put his leg out and flexed his quad and as he did he reached down to pull his balls forward and I...instinctively looked down and as I raised my eyes he was looking right at me with sort of a smile. I had my towel on but my dick was getting hard despite myself and I nervously tried to adjust to the side by pulling my towel over it but he suddenly reached out and pulled it off me.He laughed and said it was cool, and my dick surged to it’s full. I knelt in front of this man and reached out and grabbed his cock; I could tell that even soft he was easily twice as thick as me hard. I started stroking it and leaned forward and gave it a lick. I couldn’t believe that I was doing all this without any push back. I licked around the shaft and head as I stroked him; within a minute I had him fully hard and his cock was the biggest I had ever sucked by at least an inch and a half. I’m guessing he was about 8-8.5 inches total and thick enough. Then she planted a trigger word that pain was pleasure and pleasure was pain; the more pain he felt the hornier he would become and the hornier he got the harder his cock would get. All the time she knew the cylinder did not allow for his cock to swell with blood as it stiffened; so this too would add to the agony of his balls feeling like they were on fire.Ten minutes after applying the tiger balm Bob was sweating profusely and panting like a raging nymphomaniac; his balls threatened to burst. Hilbert stepped up and examined the burns. The healing rate on this guy was phenomenal. Nurse Betty was about to replace the dressing, but Dr. Hilbert stopped her. “Dr. Capstone will be here in a minute.”While they were waiting, John explained that he would like Mary to assist him in working with the patients. Dr. Hilbert was a little skeptical, but decided that if John requested it then there might be a good reason. It was then agreed that Mary would go on the rounds with him. Mary was.
