The Slave Ch. 16
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 blood 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 there is more to it than what's in the books." Because of Mark's lessened sensitivity, or high pain threshold, you will be able to fully examine the parts that you've only read about or possibly, but not likely, found inside your own boyfriends."
Most of the girls laughed, one even commenting "my boyfriend won't even let me touch his balls." They all laughed. Rachel moved in closer, between Ross' legs. She was sitting back on her legs, both hands extended out to Ross' genitals. Rachel then slid both of her hands on either side of his balls, cradling them and lifted them up higher. Doing this, Ross' cock rolled back, resting on his stomach.
Holding one ball in each hand, Rachel started "The testicle is composed of many parts, which you all know. In essence, the average testicle is a little bit larger than an almond, being very fleshy and muscled. Coming from the top of it is the epididymis, a large coil of fleshy tubes, which lead to the vas deferens. The rest of the genital anatomy is further into the body and we won't get into that. As you can see with Mark, each testicle is about avocado sized and both his epididymis and vas deferens are remarkably enlarged."
Pressing her thumbs down into the sac, she continued "You can actually feel each portion of his reproductive organs, tracing the outline of the epididymis coil, and the obviously huge vas deferens. In the average male, these are about as large as string, but in this case, you will feel that the vas deferens is just a little smaller than a drinking straw." At this point, Rachel was obvious with her fingers and thumbs digging into the soft sac, probing and feeling. "Mark, are you doing ok"? She asked. There was again, vigorous head bobbing from Ross, indicating that he felt just fine. Everyone laughed, continuing to watch Rachel's fingers, buried in his sac. "Here in a little while, I want each of you to do a complete exam on Mark's external genitalia, and a partial exam on the internal. All of the parts that I'm working right now will become familiar to you with practice. And don't forget ….. You're fulfilling Mark's fantasy."

As Rachel continued to probe and manipulate the upper portion of Ross' balls, she told the group of student nurses that she was going to explain and let them participate in the male erection, catheterizing the male, the use of sounds, and a brief demonstration in electro ejaculatory technique.
She reemphasized several times that Mark was not a sex show, even though he was willing to be their temporary patient, and request that they 'attempt' to treat him with some degree of dignity. They all couldn't help but notice that Rachel's ball manipulations were keeping Ross, rock hard. The head was engorged to the point that some of the student nurses worried about it splitting or tearing.
More evidence of his high level of arousal was the large pool of pre-cum spreading on his stomach. Rachel was very graphic when showing the young nurses where to feel, probe and where to squeeze the spermatic cord. Pushing deep into his sac and using her thumb and middle finger, she announced to the group that she was holding the vas deferens between her fingers.
Rachel started to roll the two fingers together, in a massaging, squeezing motion. Within a few seconds, Ross suddenly jerked, thrusting his hips into the air. The young nurses were amazed as they watched a large amount of sperm ooze out his head and slide down the shaft. His cock was rock hard and she had not even touched it. It was obviously sperm, and not pre-cum. Ross' breathing was hard, but returned to normal within a few minutes. Rachel then told the group, "What you just witnessed, was NOT an orgasm, but a manual release of his sperm. In theory, you could do this to him all day, without him experiencing orgasm, until he either ran out of ejaculate, or was exhausted. And yes, it did feel good ….didn't it Mark"? Ross vigorously nodded his head up and down, indicating a strong yes.
Rachel continued to probe deep into Ross' sac, massaging the other testicle. Expecting her to give a demonstration on the other ball, the nurses were watching intently as Ross' cock remained rock hard and started to twitch. Again, she was not grasping or even touching the slimy, sperm covered cock. "Let me show you another technique, with a completely different result," she said as she let go of his ball.
Her left hand reached out and took a firm grasp of his shaft, pulling the thick foreskin upward around the head. Immediately her right hand slammed into the cock head, with an open palm. Ross jerked hard, a noticeable groan coming from under the hood. Within about two seconds, Rachel relaxed her grip on his cock, as it fell soft and flaccid to his stomach. It was completely soft. All of the girls stared, gasping from the hard blow that Rachel had inflicted to Ross. "What you just saw was a technique that is ninety-nine percent guaranteed to soften an aroused male." "Believe me, I didn't hurt him.
What turned a rock hard penis into a very soft penis was not pain, but the shock of being stuck." As Rachel continued explaining, she reached out and pressed her thumbs and middle fingers into his sac, again manipulating the thick inner cords. She continued explaining to them as her fingers worked on the bloated sac. Again, she did not touch his cock. Within seconds, his cock was solid and protruding upward, a steady stream of pre-cum oozing from the mouth. By this time, both Raven and Beth were leaning in close, for a better look.
