... out from the bottom of the loin cloth. But, instinctively, without saying it, each of the girls did do the 'observe and assess' and within about one second, each of them were eyeing the huge loin cloth covered bulge. "Luckily for us, Mark is a very willing patient. As you can see, he is more developed in some areas." Rachel reached down and started untying the knot, holding the loin cloth on him. As she did, all eyes were trained on her hands. Undoing the knot, she pulled the flimsy cloth away from his body, fully exposing the thick soft cock, and massive sack beneath it. "Besides Mark 'begging' to be our patient, we have a benefit in the examination of his body. Mark is among about two percent of the male population that has very little sensitivity in his genitals." One of the young nurses asked "you mean that he can't feel anything"? "No, no, believe me, he feels everything very well," Rachel responded. "Matter of fact, with this much flesh, he is highly sensitive, but not in the same regard as the other ninety-eight percent of males. That is what makes him very beneficial for examining." With that, Rachel gently stroked the top of Ross' shaft, instantly producing a swell in his cock and a obvious elongation. "Mark can feel the stimulation that I am creating in his penis but with his large size, especially in his testicles, he can tolerate more pain stimulus that the average male. Looking seriously at the young nurses, Rachel continued, "Erection begins in the penis as ...
... bl**d flow is increased to the corpus cavernosa, the chambers running along the sides of the shaft. As the penis becomes engorged, it hardens and becomes longer, becoming more stimulated. A signal is sent to the testicles, indicating that the arousal stage has started, at which point an interior gland starts to send seminal fluid into the urethral shaft, lubricating the passage for the eventual expulsion of sperm." Rachel had continued her gentle stroking on the top of the shaft as she spoke. All of the nurses were watching the huge cock get harder and start to rise up off of his sac. Within a few moments, the head fully appeared as the foreskin slid back away. As Rachel finished explaining erection, she glanced down and rubbed her thumb and forefinger across the head, smearing the clear pre-cum around the head. "See, right on cue"! She continued rubbing the pre-cum into the head till everyone noticed that Ross was breathing harder. Giggling, the nurses continued with their gasps and comments on Ross' size. He was rock hard and sticking out obscenely. As Rachel stopped her finger manipulations, the girls all started saying to continue, keep rubbing, and make him cum. Obviously, the young nurses were very involved in the examination. And they were only getting started. Rachel thought to herself that she had chosen the right group for her voyeuristic fun. Rachel continued, "Mark also gives us a great chance to know the inside of the male anatomy. You've all studied anatomy, but ...
