Alex looked at the somewhat menacing object in the doctors hand. It looked like a ruler with sliding metal claws, not something he was thrilled about touching his most sensitive parts; but much like his last exam, he found that his apprehension and embarrassment was beginning to give way to a subtle erotic excitement. As he stood there naked in front of the doctor, waiting for his penis to become the subject of even more scrutiny, he noticed that blood flow to his organ was increasing. Alex looked down and saw that his penis, although still flaccid, was beginning to swell slightly, some of the veins becoming more prominent and the head turning slightly puffy and more pink.

"Ok Alex, this might feel a little cold" Dr Glenn said as he held the boys penis on one hand and pressed one end of the caliper against his pubic bone. He slowly manipulated the device, sliding the other metal "finger" down along the length of his shaft until barely touching his urethral opening.

Alex looked down and looked at the digital display. 6.01 inches it read, slightly increased from the fully flaccid measurement. Dr. Glenn made a quick note before turning back to his patient. Alex could feel his penis continue to grow and it was now pointing directly at the Dr Glenn as he sat in front of him.

"I just need to get a measurement of the width of both your penis and the glans, ok?" Dr Glenn said as he firmly grasped the young mans growing erection, holding it in place as he slid the fingers of the calipers on either side of the glans. Alex felt the odd sensation rush thru his entire pelvic area. The pointy metal fingers teasing the sensitive skin of his head was both uncomfortable and extremely stimulating. He felt his erection pulse to full size but was unable to point to its natural orientation as it was being held in place by the firm grip of doctor Glenn. As blood rushed into his penis, the head began to swell further pushing into the metal fingers of the calipers. Alex pulled back slightly but Dr Glenn had a firm grasp on the boys erection, holding it in place.

"Just relax Alex, I need an accurate measurement" Dr Glenn said as he made slight adjustments to the calipers until he was satisfied with the measurement. "1.53 inches" he exclaimed as he again returned to Alex's file to note his findings. As Dr. Glenn released Alex's straining erection from his grip, The boys penis proudly sprung free from the Doctor's hand, springing up and slapping against his stomach; remaining in an almost vertical orientation as he stood there.

Dr Glenn returned to his his supply counter, leaving Alex standing proudly at the end of the exam table, His naked athletic body perched on the step, his ample erection point directly into the bright overhead lights. Alex had noticed that he was beginning to enjoy this experience. There was no getting over the embarrassment of having a strange man see him naked, but the exposure was exhilarating in its own right. As he stood there, enjoying the feeling of his pulsing erection proudly on display, he noticed Dr Glenn had pulled out his digital camera and was returning to his stool positioned directly in front of him.

"I'm going to take a few pictures for your file to track your development, Alex. This will help me evaluate your body over time". Dr Glenn slid his stool a few feet back from his athletic patient. "Ok, Alex, hands behind your head and stand straight up please." Dr Glenn ordered as he turned the camera and photographed the boys entire body from head to toe. "Very good, young man, now please turn around". Alex shuffled his feet on the small step, keeping his hands behind his head. His muscular back and prominent glutes now facing the doctor. Alex could practically feel the flash of the camera hitting his nude body, knowing that images his body will forever be in the hands Dr Glenn. "Ok, Alex turn to the side please" asked the dr, as Alex slowly turned to his left. Dr, Glenn adjusted his camera while observing the pleasing profile of the boy's body. His muscular legs flowed well into his tight bubble butt and firm abdominals. His penis strongly pointing up and away from his body at almost a perfectly vertical position, his tight scrotum framed nicely between his thick inner thighs. "Good job, just hold that position for me please" Said Dr. Glenn as he took one last picture.

"Ok alex lets get you back up on the table please" Dr Glenn said, placing his camera back on the counter and pulling on a pair of black latex gloves. Alex sat back on the table, His bottom crinkling the paper underneath him as he laid on his back, he legs dangling off the end of the table, his hands instinctively placed behind his head. Dr Glenn then pulled out the stirrups from the end of the table, setting them further apart than seemed necessary.

"Place your feet in the stirrups please, Alex. We going to continue your exam with a comprehensive genital examination and STD check" said Dr Glenn as he assisted the boy in getting his feet placed correctly, his knees falling open wide. Dr. Glenn pulled up his stool, sitting so close that his face was only about a foot away from his patients genitals.

Alex felt his excitement grow. His erection was at full strength, hovering just above his stomach and his legs spread wide awaiting his thorough inspection. He then felt the doctors fingers pressing firmly into his groin on either side of his scrotum, making small circles up either side and along the crease where his legs met his body. "Any pain here, Alex?" The doctor asked as he continued to move his fingers around. "No dr, its feels ok" Alex said as he pulled his head up slightly to observe the inspection. Dr Glenn continued pressing deeply into Alex's lower stomach, sliding his hands underneath the boys full erection. Alex felt the top of Dr Glenn's gloved hands graze past his swollen and sensitive glans causing hims to activate his pelvic muscles. this involuntary movement caused his penis to bounce slightly, springing up and falling back down. " That all feels good Alex, very nice" said Dr Glenn as he moved his fingers back to the boys tight and wrinkled scrotum. Alex watched as the doctor pulled slightly at his sensitive testicles trying to isolate each one for examination. Dr Glenn rolled each testicle between his fingers, pausing every so often to pull at the tight scrotal skin in order to maintain access to each testicle individually. With each tug on his tight sack, Alex's penis would bounce around, slapping against his stomach with sharp sound each time.

"Well, Alex, You certainly have well developed testicles, I typically check their size for proper development but I'm quite sure they have reached full adult volume. have you ever had any discomfort with your scrotum being so tight?" Dr Glenn asked as he rested his finger tips on the boys tight sack. "sometimes it gets a little uncomfortable during sex" Alex said, noting that his testicles practically retract into his body during intercourse. "Thats perfectly normal, Alex" Dr Glenn said reassuringly.

"We do need to do an SDT check now Alex. It's going to be a bit uncomfortable as i'll be placing a swab into your urethra and another one into your anus." Dr, Glenn said as he reached into a drawer and pulled out two different sterile swabs. He unpacked the first swab which was long and thin, looking more like a needle with a tiny cotton ball on the end. "Ok, Alex just relax and breathe normally" Dr Glenn said as he reached down and pulled up the young man's large erection. Pulling the robust organ directly up between his legs, Dr Glenn slowly pushed the thin swab into the pink slit of the boys swollen head. Alex recoiled slightly at the burning sensation as the swab was pushed further and further. Yet to his surprise, the sensation, although painful, seemed to cause his erection to pulse harder and harder. Dr Glenn observed Alex's testicles retract slightly as he could feel the thick erection strain against his grip. "Ok Alex, you're doing great", said Dr, Glenn as he gave the swab a quick twist as he slowly withdrew it. Alex exhaled sharply and reached down to massage the head of his penis. He was somewhat surprised that he had not lost his erection but at the same time strangely enjoyed the sensation of having his sensitive hole probed in such a way.
