The following story is fiction, and all names used are fictitious and bear no resemblance to any person living or dead. It was published many years ago by me under a different nom de plume, and has been re-edited and updated.

This story describes the use of an electro-stimulation unit. Do not try any techniques described unless you have a thorough understanding of electrical principles and have been instructed in the safe operation of such a unit! All characters are over age 18.

"OK, Miss Heath, we're going to wire you up for a few experiments now. We want to get to the heart of our testing without further delay."

"What experiments? I don't think I want to continue as a volunteer here," retorted Shelly as she began to get up off the table.

"Miss Heath, in case you don't remember reading the forms you signed earlier, let me refresh your memory," said John with a casual air. "Right here above where you signed, you agreed to complete all testing required. Also, you gave us sole discretion as to what the procedures would be and when you were to be released. In other words, you're our captive subject as long as we need you."

Shelly looked at him, then at Cindy, who just smiled and nodded in agreement. Of course she had not read the forms, but she couldn't believe that she was being forced to stay here and endure this humiliation. She began to protest, but John wasn't even listening.

"Cindy, get the straps. She's going to have to be restrained," John ordered. Cindy trotted to a cabinet and produced several leather straps with brass buckles on them, as well as some leather wrist and ankle cuffs. She got back just in time to help John, who was tussling with Shelly to keep her pinned on the table.

With Shelly protesting loudly, Cindy held her arms and legs as John wrapped the cuffs around her wrists and ankles. After fastening each extremity, Cindy ran the straps to metal rings on the sides of the examination table. Shelly's arms were immobilized at her sides, while her legs were secured to the stirrups. John placed a firm cushion under her hips, raising her pelvis off the table a few inches.

They finally secured their subject with two straps across her torso; one just under her breasts and one across her lower abdomen just above her pubic mound. Satisfied that Shelly was now totally immobilized, they set about their task in earnest.

"Is this necessary? Puleeeze let me go. I'll cooperate if you just take these straps off," Shelly pleaded.

"Now, now, Miss Heath, no more fussing. If you persist in making a scene and disturbing others here, I'll be forced to gag you as well," said John flatly. Shelly closed her eyes and gritted her teeth. Anything but being gagged!

"Thank you. Now, we're going to do a study on comparative responses between males and females. You will have sensors applied to parts of your body so we can see on various monitors how you respond to various stimuli. It won't hurt, although some of your responses may be slightly embarrassing," John explained.

"Cindy, did you notice if she needed an enema?"

"No, she looked pretty clean when I took her temperature," Cindy replied. Thank God for my high fiber diet, thought Shelly. An enema would have been unbearable. Poor Shelly didn't realize what was ahead of her.

At that point the curtain covering the entrance was opened from the outside, and Shelly reflexively moved to cover herself, forgetting she was secured in place on the table. As a pair of hands held the curtain open, a gurney was pushed through the doorway and into the cubicle. The man pushing the gurney was followed by a girl, dressed the same way Cindy was, in a student nurse uniform.

Shelly gasped involuntarily as she saw that strapped to the gurney was a 20-something man completely naked and in the same position as she was, on his back, legs in stirrups, spread wide. They placed the gurney parallel to and beside the exam table where Shelly lay, with the man and Shelly facing each other. Their feet were alongside each other's head, so when each looked to their left sides, they could see right into each other's pelvic areas.

The man looked over at Shelly with an embarrassed grin, and Shelly did the same. Shelly couldn't help but look at the man's lewdly exposed crotch area, noticing his thick, prominent erection and the gleam of lubricant around his hairy anus beneath his hanging testicles. The man in turn surveyed the scene, looking Shelly up and down from her face, past her breasts, and down to her wet and matted pubic hair surrounding her pussy and anus. His cock throbbed involuntarily.

No introductions were made of the new test subject nor the two new technicians who were now squeezed into the cubicle. All appeared to be busy sorting out electrical leads, clips and plugs, and attaching them to various monitors situated on rolling instrument carts beside the two subjects.

The technicians began working on Shelly and the new man simultaneously. Shelly's senses were going wild, with her attention alternating between seeing and feeling what was happening to her, and watching with great interest what they were doing to the young man beside her.

She watched between her own legs as Cindy snapped on a latex glove and began smearing KY on her fingers. John had a bullet-shaped metal device in his hand, and she could see several colored wires leading from it. Without fanfare, Cindy's slippery finger slid all the way into her anal opening and began twisting around. Shelly could feel the cool KY up inside her slowly begin to warm from the effect of Cindy's finger and her own rectum.

As Cindy withdrew her finger and spread her asscheeks wide apart, John inserted the object into her anus, pushing the cold object in with the end of his finger until it completely disappeared into her rectum. Shelly moaned at the invasion of the cold object, and sucked in air as John withdrew his finger, leaving her with a full feeling in her bowels.

"There, Miss Heath. That's a rectal sensor that's going to be connected to our monitors. I am now going to insert one into your vagina as well," John explained.

"B...bu...but what is it going to do to me?" pleaded Shelly.

"Relax, Miss Heath," John replied. "The sensors being attached to various parts of your body are part of an experiment to test your responses to various stimuli. Also, these monitors are experimental as well, and we want to see if they can capture various physiological data such as sensory neurological responses, galvanic skin response, blood oxygen levels, heartbeat and things like that."

As John was explaining this to her, she looked over to the young man and saw the same procedure being performed on him. After lubricating his rectum, the student nurse bent down so her eyes were at the level of his anus and pushed the cheeks of his bottom apart with her palms. The technician inserted the metal bullet into his rectum as the student nurse reached over and lifted his testicles up and out of the way. When the probe was inserted, the technician told the student nurse to insert her finger to get the feeling of how far inside the device should normally be placed, explaining that it should be well past the prostate gland in a male.

As she was observing this, Shelly felt a tug on the device in her rectum as the technician untangled the wires and plugged them into one monitor with a screen and a printer. Despite her apprehension, Shelly could feel herself getting quite aroused and moist deep within her vagina.

Her attention returned to her own plight as she saw John hand Cindy a similar device and was instructing her how to insert it. Cindy lubricated the sensor with a generous dollop of KY as John placed his fingers on either side of Shelly's puffy pussy lips, and spread her outer and inner lips wide. Shelly could feel the cold air suck into her female opening as Cindy positioned the tip just inside her vulva.

"Is this right, John?" she asked innocently.

"Yes, Cindy, that's exactly where you want to be. Now just push it in slowly and guide it in with your fingers all the way. It should rest just about at the cervical opening when seated correctly," John instructed. Shelly felt the cold probe slide past her pussy lips and up inside her vaginal cavity. As Cindy put her face close to her pussy, she could feel her fingers and the device wiggling around inside.

"Miss Heath, here, is going to be a great subject," John observed. "She's already aroused and lubricated on her own. Look at the way her clitoris is standing up already!" Cindy blushed as she looked first at Shelly's genitalia, then at Shelly herself. Shelly was dying of embarrassment, made worse by the fact that they were talking as if she weren't even there!

At the same time, the other team was affixing a thin leather collar around the base of the young man's turgid cock. They had smeared electrolyte along the inside diameter of the collar before applying it to his organ. The student nurse held the head of his penis steady with one hand and pulled his scrotum down with the other, as the male technician buckled the strap onto his cock.

When the first strap was fastened, another strap with electrolyte was wrapped around the man's scrotum up near the base of his penis, leaving his testicles bunched tightly beneath it and held up off his perineum in the process.

Shelly could see his cock and balls waving back and forth as the two team members stretched the colored leads and plugged them into a similar monitoring instrument. The blushing young man stared at the ceiling the whole time, clearly mortified at having his excited cock exposed to a group of clinicians his own age, in addition to a female test subject he didn't even know.

The student nurses were both tasked with applying the remaining surface sensors to the test subjects. Flat electrodes, similar to those used for EKGs and covered with electrolyte were applied to their perineums and nipples. Shelly felt Cindy wipe off her perineum with an alcohol pad and blow on her skin to dry it before carefully placing the circular white disc mid-way between her vagina and anus.

As for the young man, the young girl first had to shave the hair off the skin of his perineum before applying the electrode. After feeling it to be sure it was smooth, she pressed the disc onto the skin over his prostate, causing a low moan to escape from her captive volunteer. Shelly could clearly see several drops of pre-cum oozing from the tip of his swollen purple cock head.

Shelly presumed that similar discs would be attached to her nipples. Not quite. The technician approached her with two wires with alligator clips at the ends. Each side of the clip was a different color: one gold and one silver.

The technician twirled each nipple between his thumb and forefinger, causing them to rise hard and erect, much to Shelly's embarrassment. When they stood up, he clipped the leads onto each one right at the nipple. The slight squeezing action on the nipple ensured they would stay hard. The clips tugged at her nipples as he ran the leads to the monitor and connected them.

The other team was done attaching the nipple electrodes to the young man's chest at about the same time. What in the world are they going to with us now, Shelly wondered as she surveyed the scene in front of her.

"We've calibrated the monitors to each of you to establish personal at-rest baselines," explained the other technician. "We will now introduce the same stimuli to you both simultaneously and record your reactions in various parts of your bodies. We will compare them later in the laboratory."

At that, the student nurses produced slim vibrators and turned them on, causing them to buzz madly. Apparently familiar with established protocol, one vibrator was touched to Shelly's right breast as the other was touched to the young man's right breast. All the technicians and their young assistants gazed at the monitors, which showed if there was concurrent stimulation in other unrelated areas such as vagina, penis, testicles or anus.

The vibrators were then systematically applied to their right nipples, both earlobes, and finally placed into their mouths. Since the vibrators had been swabbed with an anti-bacterial beforehand, there was little danger of infection when their mouths were penetrated.

The girls told the test subjects to open their mouths, whereupon they dutifully inserted the vibrators. After a few seconds of registering responses on their tongues and palates, the vibrators were slowly pushed to the backs of their throats, ultimately causing stimulation of the gag reflex.

The girls nonchalantly held their jaws open and steady as they watched the monitors for a few seconds to be sure the responses were registering properly while their subjects convulsed and struggled against their restraints. Finally, the vibrators were withdrawn, leaving both subjects panting heavily and jerking their heads back and forth.

Before Shelly and her male counterpart could recover to protest or ask a question, the girls had moved down to each one's pubic area. Taking up a position on a low stool between each subject's splayed legs, they began to touch the vibrators to various points.

The girl working on the young man began with the tip of his highly erect penis, slowly running it down the underside of his smooth circumcised shaft. Shelly could see him flexing his cock wildly, though involuntarily, and a long drop of pre-cum dew squeezed itself out of his narrow slit. The technician told the girl that was good, and to continue with "Phase 2."

She slid the vibrator down to the man's scrotum, at the same time taking the skin of his hairy sac at the bottom and stretching it downward so the shape of his testicles could be seen on either side. She ran the tip of the vibrator first down the center between his balls, then circled the left, then the right one with her vibrator. The technician was watching the monitor intently and was making notations on the paper strip emanating from the machine.

At the same time, Shelly was having the vibrator applied to her clitoris. The girl had spread her lips wide, and with a slight upward movement pulled back the clitoral hood enough to get the tip right on the swollen pink button. Shelly wiggled and squirmed her hips...she was so sensitive by now, she was afraid she would cum in front of everyone and embarrass herself even more.

Mercifully, the vibrator was lifted from her clitoris, but then suddenly she found it penetrating her vagina. Her pussy lips quivered and quaked and the juices flowed out of her so much that the male technician on her team had to wipe her off with a Kleenex during the procedure. It was apparent that the young girl assistant had done this many times before, maybe even to herself, as Shelly observed she was very skilled in applying the vibrator to just the right areas.

Finally, the vibrators were removed and both test subjects collapsed into heaps on their respective tables, staring up at the ceiling. They were both thinking that there couldn't be much more and they were going to be allowed to leave, when the young man noticed one of the girls applying great globs of KY to the vibrator.

"Wh...what are you going to do now?" he whimpered.

"The final test requires that this stimulator be applied inside your rectum," the girl said with a combination of shyness and mischief showing on her face. She seemed to be breathing a little harder than before; could she be getting off on what she was putting these two subjects through?

Both student nurses resumed their positions on their stools. Looking closely at the shiny, pulsating anuses only inches in front of their eyes, they spread the buttocks and inserted the vibrators. Both subjects gasped out loud as their rear orifices were violated once again.

At first, they only pushed them in about an inch, stopping to let the sensations of the anal sphincters register. Then they pushed them in to a depth of about three inches, just short of touching the already-inserted probes, and held them there while they looked back at the monitors. Finally, they slowly withdrew the vibrators, allowing the anal rings to close slowly around the tapered tips.

"We have to redo the prostate reading on your subject," the other team's technician told his assistant. "Insert it again, only about an inch, and tilt it so the tip goes upward and contacts his prostate."

The girl, almost gleefully, pivoted back to face her subject's crotch, lifted his testicles and deftly inserted the tip of the slim vibrator, carefully watching how far in it went. Then she slowly angled her end downward, forcing the tip inside up toward his testicles. The young man bucked his hips on the table and groaned loudly as she found his prostate, which produced a sly smile from both girls as they exchanged knowing glances.

They both were trained in how a boy's "good spot" reacted to stimulation, and each loved to produce the predictable reaction in their test subjects whenever possible. Shelly watched in amazement as the young man had his anus penetrated and his ensuing reaction. She would definitely remember this lesson for her future sexual encounters!

The readings being finally recorded to the technician's satisfaction, the vibrator was withdrawn, almost reluctantly, just before the man was about to shoot his load all over himself. Shelly knew how mortified he would be if that happened, yet she was praying it would so she could watch his sweet agony. At least SHE would not be humiliated by ejaculating if she happened to cum.

"John, are we going to reward these two today, since they were so cooperative?" asked Cindy with noticeable anticipation in her voice. "Yeah, can we?" chimed in the second girl with a smile.

"Yes, Doctor Peters has allowed that in the past. We certainly don't want these two leaving in the condition they're presently in. The streets wouldn't be safe," he chuckled.

The technicians removed several of the colored wires from the monitors and plugged them into a different machine with a meter and several rotary controls.

"For being good subjects today, we are going to stimulate you to orgasm electrically. Have you ever experienced that?" he asked, looking at both of them.

Both weakly shook their heads and whispered "No." They couldn't stand their sexual tension anymore, and were grateful that they would be allowed to cum. They didn't even care at that point that each would be watching the other, or that everyone else would be watching as well. They just had to cum!

"I'm going to send a harmless electrical current through your rectum and genitals using an electro-stimulation device. You will at first experience a tingling sensation, then a pulsating feeling as your muscles contract in time with the electrical impulses. I will start out slowly at low intensity, then increase both the intensity and frequency of the pulses until you orgasm. Here we go."

The girls watched the subjects intently, waiting for their reactions. As the technician slowly adjusted several dials, Shelly could feel a light tingling going up from her anus to the clitoris, then the promised anal contractions began, along with some minor contractions along the upper part of her slit around the clitoris. The young man got the same tingle, except his went from his anal ring up through his prostate to the base of his cock. He bucked his hips at the first pulse, then began gyrating his buttocks on the table the best he could within the confines of the restraining straps. The two girls looked at each other and suppressed a giggle, knowing what was coming next.

As the technician increased the frequency and intensity of the pulses, Shelly began pressing her buttocks down into the table as much as she could manage, adding more pressure to her throbbing clit. She looked over at the young man and wished she could grab his cock right now and do everything in the world to it. She was so aroused!
