PART I
Shelly Heath walked into the Physio-Lab, Inc. offices a little after four p.m.
on a sunny Thursday afternoon in early October. Shelly was a 21 year old junior
at the nearby university, who was enrolled in the business program. Shelly was
single, with no steady boyfriend at the time. A flyer on the bulletin board in
the student dorm where she was a resident assistant had asked for volunteers for
a grant-funded research program attached to the university's physiology and
physical therapy programs. The flyer had announced that students were sought for
two to four hours of their time so that various physical characteristics could
be studied. Shelly had a bit of spare time on her hands, being the first part of
the semester. Since she was athletic, she figured that the research could
someday help her and others with sports injuries and subsequent rehabilitation.
Upon entering the clinic, Shelly was greeted by a receptionist, a pleasant woman
maybe a few years older than her, who smiled and handed her a health
questionnaire and a waiver form. After filing out the usual health history
questions and scanning the waiver quickly (it all looked the same no matter what
form it was) she signed them and handed them back to the receptionist. After a
brief wait as she read a health/fitness magazine, a young man called her in.
"Miss Heath? Would you come in please?" asked the pleasant looking young man in
a white lab coat, who Shelly mentally gauged to be about twenty years old and
fit. Shelly followed him through the door to the right of the receptionist and
down a short hallway. At the end of the hallway, they went through another door
with a sign saying "Authorized Personnel Only." Inside was a larger hall that
was partitioned off with high cubicle-type room separators. As they began to
walk to the left, Shelly noticed a low murmur of activity consisting of various
noises, grunts and low-level conversation being spoken in short
sentences...almost like commands. Some of the cubicles she passed had curtains
stretched across the openings, and a few did not. As she passed one open
curtain, she noticed a woman on an exercise bicycle pedaling furiously and
showing obvious signs of exertion. Suddenly Shelly noticed something odd...the
woman was wearing only a pair of skimpy panties and was completely naked from
the waist up! There were some sort of clips with wires attached to her nipples,
but it was unclear what their purpose was. Calmly watching the woman was a young
man wearing a white lab coat and making notes on a clipboard. Shelly was about
to ask her escort what they were doing in that cube, but he suddenly pulled a
curtain aside and asked her to step in. "This is where we'll be testing you
today, Miss Heath," said the young man. Shelly noticed that the cube was about
ten by fifteen feet in dimension, with an exam table, a counter with various
instruments on it, and some other devices that looked like monitors and wires,
etc., on a rolling equipment cart. "Before we start, we have to give you a quick
exam to ensure you're in good enough shape to be one of our study subjects," the
young man stated. "Please take off your clothes and have a seat on the
examination table, and someone will be with you in just a few minutes," he said
pleasantly. Shelly wasn't expecting to have to be undressed and examined, but
then rationalized that since this was a physiology study, it would stand to
reason that access to certain parts of her body would be necessary. Without much
of a thought, Shelly undressed down to her bra and panties, figuring that would
be sufficient. She pulled back her auburn hair into a ponytail, letting it fall
over her taut, youthful body. She prided herself on her fitness, and was proud
of her muscle tone. She sat on the exam table, looking around at the sundry
devices, wall charts, etc., when she became aware of some muffled noises coming
from the adjacent cubicle. She quietly slipped off the exam table and padded
over to the corner in her bare feet, trying to listen more closely to what was
taking place next door. She saw a sliver of light piercing a separation in the
modular wall joint, and pressed her eye up to it. What she saw amazed her. Off
to her left was a girl who looked like she was Shelly's own age, wearing a white
blouse under shoulder straps of a dress with vertical pink stripes. She was
holding a clipboard on which she was writing, as well as a small black box which
she cradled between her abdomen and the lower end of the clipboard. On the floor
in front of the girl, and in profile to Shelly, was a young man who was doing
pushups and showing obvious signs of exertion. The boy was naked except for an
athletic supporter, which gave both Shelly and the young monitor a Birdseye view
of his clenched buttocks. Shelly blinked as she noticed a pair of thin black and
red wires leading from between his asscheeks to the black box held by the
monitor. A similar pair of wires ran to the box from underneath the jockstrap's
pouch holding his genitals. As she pressed her eye to the crack, she could see
the young man straining to squeeze out more pushups. The young girl finished
writing and looked down at the boy intently. "Keep trying, David...don't give
up. You know what will happen if you give up, don't you?" asked the girl, with
what seemed like an amused smile. "Y...yes, ma'am," David huffed. 'Ma'am?'
thought Shelly. He's calling this young girl 'ma'am'? And what was her comment
all about, anyway? Shelly was captivated by the scene in front of her, even
though she didn't completely understand it. After squeezing out one last pushup,
the boy collapsed to the floor, huffing and puffing. "I'm sorry, I just can't do
any more!" The girl looked down at him and shook her head slightly, as if to
say, 'Oh well, there's nothing I can do for him now.' She repositioned the black
box on the clipboard and pressed a red button. Immediately, the young man on the
floor before her jumped and yelped. "OK OK OK.....here I go...I'll do more..."
he blurted out in a rapid-fire staccato, as he pushed himself back up into the
leaning rest position. "David, you know that I'm required to discipline you if
you show a lack of motivation. Doctor Peters' orders, you know," said the girl
with a smirk. As David remained in position, the girl moved forward and bent
down over his backside. With her free hand she parted his buttocks and made some
adjustments to whatever device was inserted in his rectum. With her fascination
at what she was seeing, Shelly failed to hear someone enter her cubicle behind
her. "Interesting, isn't it?" said a female voice behind her. Shelly jumped and
spun around to see a young female dressed the same as the monitor in the other
cube, accompanied by a young man of about twenty-four wearing a white lab coat.
Shelly couldn't find anything to say, but now was acutely aware that she was
standing there in just her bra and panties. "My name is John," he said, "and
this is Cindy. We're going to be the research technicians who will be testing
you today." Shelly smiled and said hello. "Let me explain the volunteer program
to you briefly," John said. "Doctor Peters is the senior supervising physician
on this project. I'm a physiology grad student at South Central University and
Cindy, like others here, is a nursing student who also volunteers at the local
hospital." 'Student nurses?' thought Shelly. 'Aren't they a bit young and
inexperienced for this sort of thing, especially taking charge of nearly nude
volunteers their own ages?' "Don't be concerned with what you've seen so far.
That has to do with the exercise physiology project. You will be part of the
sensory/stimulus study project. No endurance testing for you," he continued with
a chuckle. "But first, you have to have a quick physical so we can get some
baseline readings." Cindy took Shelly's arm and guided her over to the scale in
the corner of the cubicle. "OK, Miss Heath, I have to weigh and measure you for
the record. I need you to remove your bra and panties now," said the girl. "Why?
They don't affect my weight at all..." said Shelly before being cut off. "Miss,
all our test subjects ask the same question. Dr. Peters requires totally
accurate statistics, and our instructions are that height and weight will be
taken with our subjects completely nude. Now please remove your bra and panties
for me," explained Cindy. Shelly hesitated for a fraction of a second while she
glanced over at John, then with a sigh of resignation unhooked her bra in the
rear and let it slip over her arms and off. She slid her thumbs under the
elastic waistband of her skimpy white panties on either side of her hips and
pulled them down to her knees, bending forward slightly. She wiggled her legs
until the panties fell lifelessly to her ankles, where she stepped out of them
and kicked them off to the side where her other clothes lay. Now she was
completely naked in front of these two young strangers. "OK, Miss Heath, up on
the scale, please," Cindy said. Shelly stepped up on the traditional doctor's
scale where Cindy adjusted the weights on the balance beam until they showed a
reading of 125 pounds. Cindy called out the weight to John, who duly noted it on
his clipboard. Cindy moved behind Shelly and placed one hand on her abdomen just
below her breasts and the other on her lower back just above the cleft of her
buttocks where she had a dimple on either side at the base of her spine. Her
hands felt a bit cool and they were smooth. It was a strange, but vaguely
pleasant sensation; she couldn't ever remember being touched like this by a
young girl. "Now, I want you to stand up nice and straight so I get an accurate
measurement," explained Cindy as she pressed her hands inward to straighten
Shelly's posture. Shelly had moved her hands forward to cover her pubic area,
but Cindy had pulled them back to her sides, telling her to stand at attention.
When the top bar of the scale was touched to the top of Shelly's head, Cindy
called out the height of 5'6" to John. Shelly was then allowed to step off the
scale, and went immediately to her clothes and quickly pulled on her panties and
began slipping her arms through the bra straps before being stopped short by
John. "Woah, not so fast. We're not done with the baseline vitals yet. Leave
your bra off for now," he told her. Shelly, who was starting to feel a bit more
comfortable thinking she could cover up, thought of protesting, but remembered
she had volunteered for this and mentally agreed to cooperate. She dropped her
bra back down onto the clothes pile. "Come on over here so we can get some
vitals," John told her. She walked over to the exam table and began to climb up,
when Cindy put a hand on her shoulder, stopping her. "We can do this all at once
while you're standing right here," she said. I want you to face the table and
bend over it. I suggest you grab the opposite edge to keep yourself steady."
Shelly had never heard of this happening during an exam before, but she already
had the uncomfortable feeling that this examination was going to be different.
Shelly faced the table and leaned over until her hands were at the opposite
side. She felt Cindy's dress brush against the bare backs of her thighs as she
pushed Shelly's groin into the side of the examination table and extended her
arms fully toward the other side. With a hand in between her shoulder blades,
Cindy pushed Shelly firmly down until her nipples pressed against the paper
covered cushion. The cool feeling and the friction of her nipples brushing the
paper caused a tingling sensation which began to embarrass Shelly. She
voluntarily pressed her breasts into the cushion, hoping to hide their erectile
state from the two technicians. Without further warning, Cindy's fingers slipped
under the edge of her panties and began to tug them down her legs and thighs,
past her knees, and finally down to her ankles. Cindy raised the right foot and
slipped the panties off of it, leaving them circled around the left ankle.
"Spread your legs wider for me," Cindy ordered as she placed her hands between
Shelly's thighs and forced them outward until they were about two feet apart.
"What's this all about?" asked Shelly nervously. "We're going to take your
temperature, pulse and blood pressure," explained John. Since we do all three at
once, it won't take long at all." "You don't mean a rectal temperature? I
haven't had that done since I was a kid, for God's sake," cried Shelly with
alarm. She began to raise up off the table and turn around to speak to John
about this, but he pushed her shoulders back down and told her to stay still for
the procedures or they would have to begin all over again. "Dr. Peters insists
on accuracy in all our readings, as we've explained. The rectal and vaginal
temperatures are the most accurate and least susceptible to external effects or
manipulation," explained John. "Now, we expect you to cooperate without further
fuss, OK?" Cindy had already brought over the blood pressure cuff and
stethoscope as well as several thermometers and a tube of KY jelly, setting them
on the exam table beside Shelly. Shelly couldn't take her eyes off the
instruments, knowing they would soon be used to violate her private body parts.
While Cindy began smearing KY over the thermometers, John picked up a latex
glove and pulled it on with a snapping noise. He used the fingers of his other
hand to push down the glove between his fingers so the glove was on tight. He
flexed the gloved fingers several times before holding out his hand for Cindy to
squeeze some KY onto his first two fingers. With his fingers all slick from the
clear lubricant, he stepped behind Shelly and waited for Cindy to spread her
taut cheeks with her fingers. Shelly could feel his warm breath on her fine anal
hairs, he was so close, and she could feel her face turning red with
embarrassment at having complete strangers see her most private hole up so
close. She suddenly felt the cool KY on the tip of his gloved finger lightly
touch the outside ring of her anus, moving in small circles all around the
outside edge....then slowly finding the center of her target. His fingertip
began pushing in past her sphincter. "OHHHHHH......do you really have to do
this? I don't think I can take this," whined Shelly as she began to squirm.
"Yes, Miss Heath, I have to lubricate you for the thermometers. Otherwise they
won't insert comfortably and you'll complain about that, too. Just relax and let
it happen," instructed John. Seeing that Shelly was getting restless, he turned
to Cindy. "Cindy, go around the table and hold this lady's shoulders down for
me, would you? I don't want her squirming around so much while I'm working."
Cindy went around to the opposite side of the table where Shelly's head was and
took hold of her shoulders. Shelly looked up at the young girl's eyes, and
caught the sense of glee at being able to force this on her. The girl had a
surprising strength, and Shelly felt her breasts being pushed into the table
cushion. As she was being held down, Shelly felt her cheeks being parted again,
and this time the tip of the thermometer remained poised at the entrance to her
rectum. She felt the cold silver bulb of the tip touch dead center on her
wrinkled hole and scrunched her anus in response. After the initial "wink"
reflex, she felt the thin glass tube enter her behind...going in all the way.
She thought that would be it, until she felt another thermometer being inserted
in her rectum. "What...?" "Relax, Miss Heath, this is standard procedure here.
We have to use two thermometers to verify readings," said John as he cupped his
hand across both her buttocks and over the ends of both thermometers. Shelly was
apprehensive that this was beginning to go too far, but in spite of that, she
felt some stirring in her groin. Oh, God, how could she be getting aroused at a
time like this? After four minutes was up, John slowly slid one thermometer at a
time out of her puckered hole and recorded the readings. Almost as an
afterthought, the told Cindy to check her nipples. "Cindy, would you check her
nipples for me, please? You know what the sensors are like...see if they'll fit
on her." Cindy motioned for Shelly to lift her chest a bit, and slid her hand,
palm up, under her hanging breasts. Slowly, she worked her way around each
breast until she felt the nipple. She took each nipple between her thumb and
forefinger and rolled them back and forth. Shelly's nipples were tingling
before, but now they were rock hard and perfectly erect. "I think they'll fit
just fine, John," she reported. "They're very responsive and seem long enough to
fit into the terminals." John finished making his notes, then returned to
Shelly. "OK, now I want you to hop up on the table and lie down on your back for
me." Shelly was only too happy to get out of that humiliating position and
assume a supine position on the table. She felt relaxed now, feeling the
flexible cushion and clean white paper underneath her bare posterior. She placed
one arm over her breasts and the other hand over her pubic mound, somehow
thinking that her modesty was being restored. As soon as she assumed the
position, John ordered her to move her bottom down to the edge of the table and
place her feet in the stirrups. She hated that position, remembering how exposed
she was during her regular gynecological exams. She took a deep breath and
slithered her butt down to the end, and one by one raised her legs to rest them
on the full-length stirrups. John adjusted them so they brought her knees back
toward her breasts and raised her feet. Then he opened them wide, so she was
completely exposed. Shelly had never felt the rush of cool air on her asshole
and pussy at the same time like she did now. She saw Cindy shaking down another
thermometer, and wondered what that was for. "Wait...you just took my
temperature..." Shelly blurted out. "Yes, that was the rectal temp. We are also
required to take a vaginal temperature as well to confirm the readings and add
to our database," Cindy explained. "Don't worry, it's painless." Cindy went to
the edge of the table and got right down between Shelly's legs. She spread her
puffy lips nice and wide, then inserted the thermometer until only about an inch
protruded. While the thermometer was inside, Cindy and John both did an external
examination of her genitals. They spread her lips apart and examined the pink,
wet inner lips, poked and probed and spread open her peehole, and finally found
her clit. They pulled back the skin covering the little button and exposed the
slick pink swollen organ. John grabbed it between his fingers and squeezed it
slightly, causing Shelly to twitch her hips. Cindy giggled and told John to quit
it, as they would see enough of that later. Shelly was certainly
excited...obviously related to the fact that she was naked and exposed to these
two young people. But she was becoming more embarrassed and wasn't sure she
wanted to continue with this project. When time was up, Cindy removed the
thermometer and read the temperature to John, which was again normal. John
looked satisfied as he reviewed her chart.
PART II
"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. 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 young man pushing the gurney was followed by a young 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 young 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 along side each other, 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 up 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 fanny 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 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 some electrolyte along the inside
diameter of the collar before applying it to his organ. Again, 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 another 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 perineum's and nipples. Shelly felt Cindy
wipe off her perineum with an alcohol swab 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
adults 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 four inches
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 captive subjects whenever possible. Shelly watched in amazement as the
young man had his anus penetrated and his ensuing reaction. She would definitely
have to 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 said with a smirk. 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 a device called a TENS unit. 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 horny! Finally, both subjects began moaning louder and
thrashing around. The four techs looked on as first the young man, then Shelly
came to explosive orgasms right in front of their eyes, without anything even
touching their genitals. The pair came amidst a chorus of grunts, moans and
choked sobs, leaving no doubt that they were experiencing very powerful orgasms.
Amazing! It seemed the student nurses never tired of watching this phenomenon,
which had been explained by, then later demonstrated by, Dr. Peters. It was
decided that they should use this technique as a reward for cooperative subjects
so they would be unlikely to spread the word about how truly humiliating their
experience had been at the hands of these young student researchers. Shelly and
the young man laid back, covered with a light sheen of perspiration, eyes
closed, both out of relief and acute humiliation at having experienced something
so personal before a rapt audience. Once it was clear that both subjects were
post-orgasmic, the student nurses busied themselves with detaching all the
surface electrodes, then finally gently tugging out the sensors in Shelly's
pussy and rectum, and the young man's rectum. They swabbed both genital areas
clean from all lubricant and body fluids. The girl on the other team had the
extra task of cleaning off the young man's abdomen with a warm washcloth,
sopping up his great load of spent semen. As Shelly was being untapped, they
began to wheel the young man out of the cubicle, still fastened to his gurney.
Shelly and the man looked at each other, and she wasn't sure, but she could have
sworn that he gave her a little wink just before he disappeared out the doorway.
"I hope this experience has not been too unpleasant for you, Miss Heath," said
John. "We do appreciate your participation this afternoon. The data we collected
from you will certainly be valuable to our database for future research."
"N...no, everything was fine. It was the strangest thing I've ever
done...but...oh, never mind. Can I get dressed and go now?" Shelly asked weakly,
not wanting to meet his gaze. "Yes, get redressed and Cindy will lead you out.
Again, thanks for volunteering," John said as he stuck out his hand to the naked
woman. Shelly took his hand and shook it, and to her surprise, she held it for a
split second longer than she wanted to. John looked her up and down quickly
before telling her, "All right now, you'd better get dressed." Shelly turned
away quickly and donned her clothing as quickly as she could. Her clothes felt
almost weird since she had been naked for so long. When she was done, Cindy led
her to a different vestibule, where she was asked to sign out. Shelly and Cindy
exchanged quick good-byes, then Shelly was out the door. She didn't even look
back at the building as she walked down the street in a daze toward her dorm
room. Shelly thought about her experience over the next two weeks, her confusion
and embarrassment gradually fueling her masturbatory fantasies, until she
finally picked up a leftover flyer at the dorm's front desk and headed back to
the lab. When she got to the address, she found the doors locked, and the Physio-Lab
sign had been removed. She looked around to see if they had moved to another
location, and even double-checked the address on the flyer. It sure looked like
the same place she had been only a couple of weeks ago. She crossed the street
and sat down on the front steps of an apartment building, just staring at the
former location of her Physio-Lab experience. She let her mind wander,
recreating her sensual experiences there. She finally crumpled the flyer and
threw it into the hedges near the steps and slowly walked back to the dorm. Only
one question was on her mind at that point. Would she ever run into the other
young test subject again? And what if she did? End
