   Maria Returns to Sato's Studio

   by anon1940

   It had been several weeks since Maria and I spent the weekend together.
In fact, for a period, we had no communication of any sort.  Assuming that
she was still coming to terms with her memories of the time that we spent
together, especially our visits to Sato's studio, I decided to wait for her
to renew our relationship.  On the one hand, in our conversations prior to
our meeting, she had unequivocally expressed her desire to spend a weekend
devoted to hedonistic activities.  On the other hand, I was not sure that
she had anticipated the extent to which she would have to abandon all
semblance of modesty and relinquish control of her body into not only my
hands but also those of strangers.  Surely, she must have wondered at her
own compliance in Sato's obscene display and Yoko's skilled manipulation of
her most intimate erogenous zones.  My hope was that she would find that
her feelings of the shame associated with these memories were amply
compensated by her memory of the pleasure that her self-immolation had
afforded her.  Indeed, I harbored the hope that, after sufficient time, she
would recognize that the shame had been an integral part of the pleasure,
at which point she might choose to immerse herself again into a world in
which gratification of her carnal instincts takes precedence over all other
considerations.

   Determined that the decision should be hers alone, I refrained from
contacting Maria and was resigned to accept her choice, whatever that might
be.  Nonetheless, on the chance that she would eventually want to again
indulge her sexual fantasies, I engaged in a little research.  It is clear
to me that Maria is fascinated by her own body and enjoys having that body
made to perform to its full potential.  Although she is no masochist, she
knows that to achieve its full potential, her body must endure a certain
amount of suffering, and, as she demonstrated during our weekend together,
she is willing to accept suffering if it enables her to reach her goal. 
While browsing the web, I came across a video which shows a young woman
being relentlessly stimulated by an array of strategically placed
electrodes attached to her body.  The woman is lying naked on her back on a
table to which a steel frame is mounted at the corners.  Both her arms and
legs are connected to this frame so that she cannot reach the electrodes
with her hands and her legs must remain raised and separated in a way that
leaves her crotch blatantly exposed and available.  From the anguished
expression on her face and the contortions wracking her body, it is obvious
that her attention is entirely consumed by the stimulation that she is
receiving.  What is less obvious is whether what one is watching is a woman
in torment or a woman in the throes of ``la petite mort.'' In either case,
the resulting image was compelling and one which I would very much like to
see Maria reproduce.

   About two months after our weekend together, Maria at last sent me a
message in which she indicated that she would like to renew our
relationship and was ready to engage in further exploration of her
fantasies.  Having done my homework, I was well prepared and sent her the
link to the video that I had seen, asking her to view it and tell me what
sort of experience she thought that the woman in it was having.  The next
day, Maria wrote back that she had watched the video and come to the
conclusion that the woman's contortions were expressions more of sexual
ecstasy than of agony.  As she put it: there were no tears, only a sequence
of multiple orgasms.  In addition, she said that she found the woman's
contortions displayed her body in manner which was both beautiful and
profoundly moving.  Emboldened by her response, I asked her if she thought
that she might like to find out herself what that woman had experienced. 
Two days later, Maria wrote back that, if I thought that I could arrange
it, she would be willing to play the role that the woman had played in the
video.

   Not knowing where else to turn, I somewhat hesitantly called Sato's
studio to ask whether he knew of a place that had the requisite equipment
and expertise for this sort of thing.  To my relief, he was neither shocked
nor surprised by my inquiry and said that his own studio catered to people
seeking this source of sexual gratification.  Further, he recalled Maria
and our previous visits to his studio and said that he would be happy to
have an opportunity to renew his acquaintance with Maria's body.  However,
he expressed concern that Maria have no illusions about what she would be
subjecting herself to.  I tried to allay his fears by explaining that,
having watched the video I had sent her, Maria could have not help but
understand what she was getting into.  Apparently satisfied by my answer,
he agreed to provide the services that we were seeking.  Our conversation
ended with his telling me that he would send me a list of instructions
detailing the preparations that Maria would have make prior to our visit.

   I relayed all this information to Maria, including Sato's list of
instructions.  Maria wrote back that the more she learned the more she was
determined to carry the plan to completion.  Nonetheless, because she was
expecting her period soon and did not want to take a chance on its spoiling
her experience, she would postpone her trip until the weekend after next.

   Just as on her previous visit, I met Maria at the airport.  As soon as I
saw her, it was clear to me that her state of mind was quite different from
what it had been when she arrived the last time.  The look of excited
anticipation that she had had was replaced by one of considerable
apprehension, and the provocative outfit that she had worn had been
replaced by a sedate skirt and sweater.  No explanation was needed to
account for these changes.  I could well understand that Maria had spent a
lot of time contemplating what lay ahead and that to proceed required all
the courage that she could muster.  Nonetheless, as I learned when we got
to our room at the hotel, even if she had anxieties, she was stalwart in
her resolve.  As soon as I had closed the door, she began preparing herself
for our return to Sato's studio.  Meticulously following the instructions
which Sato had sent, she divested herself of the skirt and sweater in which
she had traveled, thereby revealing the fact that there was nothing under
these banal garments other than her own pink flesh.  After giving me the
opportunity to visually appreciate but not tactically examine what lay
beneath, she reminded me of the restrictions that Sato had placed on her
sexual activity during the day preceding her appointment.  Namely, although
mild stimulation was permitted, and, in fact, encouraged, consummation was
to be avoided.  For this reason, she announced that, after taking a warm
bath, she would limit our sexual activity to foreplay.

   Maria spent more than half an hour in the tub, and, by the time that she
reappeared, I was pleased to note a marked diminution in her earlier
tension.  Wearing nothing but a turban improvised out of a towel wrapped in
her damp hair, she exuded a sense of confidence and contentment that had
been missing before.  Positioning herself in front of the mirror over the
dressing table, she rubbed hair with the towel while rotating her lower
body in a subtly provocative manner.  Watching her, I could not help
wondering what thoughts she was having.  Was she trying to imagine what
that body would look like when it was forced to perform wild gyrations
rather than the languorous undulations reflected in the mirror?  If so, how
should I account for her apparent confidence?  Was it an expression of pure
bravado or of insatiable curiosity?  Well aware of the effect that she was
having on me, Maria invited me to join her at the mirror.  Happy to accept,
I approached her from the rear and, reaching under her raised arms, placed
my hands on the deliciously available breasts whose reflected image seemed
to be beckoning for my attention.

   Conscious of the restrictions that Sato had placed on us, I began
slowly. Cupping their undersides, I gently massaged those firm mounds of
succulent flesh.  I had always enjoyed molding Maria's breasts like a baker
kneading dough.  Her breasts are wonderfully malleable, and she derives
great pleasure from their manipulation.  Circling them around their base, I
pressed my fingers together to force them forward so that their nipples
were presented in the way that mother presents hers to a suckling child. 
In response to the pressure behind them, her already erect nipples became
even harder and her aereolae expanded.  At the same time, Maria allowed her
back to slump against me until, with her buttock was pressed against my
crotch and her hands resting on the back of my neck, she was espaliered to
my front.  I knew that she was tacitly begging for attention to her
distended nipples, but I ignored her plea and continued palpating her
breasts, manipulating them so that their intricate web of mamMaria ducts
would exert a steady pressure behind the nipples to which they lead.  As
her nipples swelled, she ground her hips into my groin but resisted the
temptation to either voice her growing frustration or to withdraw her
breasts from the source of that frustration.

   In the past, Maria and I had experimented to find out if she could be
induced to reach orgasm by the stimulation of her breasts alone, and on one
occasion we had succeeded.  What we had learned from that experiment was
that the resulting orgasm was of a distinctly different nature from those
which she had during intercourse.  On the one hand, it was both mellower
and more protracted.  On the other hand, it did little to take the edge off
her desire for further sexual gratification.  For this reason, I decided
that using her breasts to give her an orgasm would not violate the spirit
of Sato's instructions.  With this in mind, I finally released her right
breast and placed the palm of that hand directly over the nipple of her
left breast, which I continued to squeeze with my other hand.  By moving my
hand a circles, I forced her distended left teat to rotate on its moorings,
causing Maria, as she told me later, exquisite sensations that emanated
from her nipple and coursed down a path that terminated in her vulva. 
Warning her that I intended to continue this insidious form of torture
until she achieved orgasm, I watched with fascination Maria's body respond
and finally prepare itself for orgasm.  At the onset of her climax, she
emitted an anguished cry of frustration as she pressed her crotch down on
my fully erect but unavailable penis.  By way of compensation, I captured
her nipples between my fingers so that she would be stretching them each
time that she pressed herself against my groin.

   Not wanting to diminish my own excitement about the events scheduled for
the morrow, I refused Maria's offer to provide me the release that I had
provided her.  Instead, we went out for a light dinner at a local
restaurant.  Had it not been for the attire that Maria chosen, our meal
would have been rather bland.  However, to my surprise, she chose to wear a
wrap around skirt, a semi-translucent blouse, sandals, and nothing else. 
As a result, I was confronted throughout our dinner by the scarcely veiled
outlines of her erect nipples and, when she shifted her legs, an occasional
glimpse of her naked thigh.

   We returned to our room late enough to get ready for sleep.  Both of us
were excited about the events scheduled for the next day, my excitement
unalloyed and Maria's mixed with apprehension.  Thus, sleep was slow in
coming, and, when it did, Maria's was frequently interrupted.  Nonetheless,
when I woke the next morning, Maria's final preparations were already
underway.  I found her in the bathroom, where she, in the tub, she was
assiduously removing her body hair.  Normally, Maria kept her vulva and
armpits shaved, but, in accordance with Sato's instructions, she was now
removing the sparse hair that covered her torso.  When I appeared, she
asked me to shave the valley between her buttock, shifting to her knees so
that that region was made available to me.  Presented with Maria's
luxuriously padded buttock spread before me, I was happy to oblige.  After
lathering the delicate flesh out of which the unwanted strands of hair
grew, I carefully applied Maria's razor to a portion of her anatomy to
which she would have difficulty applying it herself.  Needless to say, I
had never performed this service before, but, drawing on the experience of
having shaved my own face for many years, I believe that I performed it
with reasonable skill and minimal damage.

   The next step in Maria's preparations was one that I knew she would have
preferred not to take.  Namely, Sato insisted that her bowels be thoroughly
purged when she arrived, and he had even specified how she was to
accomplish this.  Namely, she was to first give herself an ordinary enema
to clear her bowels.  Once they were clear, she was to repeat the process,
this time with sudsy warm water which was to remain inside her for five
minutes.  In order not to add embarrassment to her discomfort, I retreated
to the bedroom so that she could carry out these intestinal ablutions in
private, but, to my surprise, Maria soon joined me there.  I had heard the
toilet flush, marking what I interpreted to be the conclusion of the first
enema, but far less than the prescribed five minutes had elapsed since
then. The explanation was that, after absorbing the second enema, Maria had
looked down at and placed her hands on her abdomen.  To her astonishment,
what she had found there struck her as quite beautiful.  Filled with soapy
water, her bowels had pushed her lower belly forward so that she resembled
the statue of a medieval Madonna.  Pleased by the effect and not knowing
how else she to spend the time before she could relieve her bowels, she had
decided to share the image with me.  After approaching the couch on which I
was lying, she took my hands in her own and placed them on the inverted
bowl into which the region between her waist and crotch had been
transformed.  I too was entranced by its shape and texture and was happy to
spend the next several minutes tracing its contours with my fingers.

   Once Maria had completed her second enema, she had completed the
instructions that Sato had given.  Thus, the next time that she emerged
from the bathroom, it was to dress for the trip to our appointment.  On the
way, we stopped for a perfunctory breakfast, hers, in accordance with
Sato's demands, consisting of nothing but liquids.  Upon our arrival, we
were greeted by Yoko, who, as always, was exquisitely dressed in a kimono
that, though modest, subtly displayed the appeal of her petite figure. 
After we entered, Yoko escorted us to a reception room, where she indicated
that I was to sit until I was asked to join them.  She then took Maria by
the hand and led her away.

   Quite some time passed before I was summoned, and it was not Yoko who
summoned me.  Instead, my guide was another one of Sato's female staff. 
Without a word, she brought me to the room in which Maria had had her
introduction to shibari.  This time the center of room was occupied by a
large table surrounded by several pieces of sophisticated looking
electronic equipment, and lying naked on her back in the middle of the
table was Maria.  Her hands were held on either side of her head by padded
cuffs, and a harness attached to her thighs supported her legs, which were
bent and spread.  Her bonds were carefully adjusted so that, although she
could neither use her hands to protect her body nor move her legs to reduce
her blatant exposure, she had considerable mobility.  Having watched the
video that had inspired our return to Sato, we both knew that she would
soon be exercising that mobility.

   Considering her situation, she looked remarkably calm.  There was a
contented smile on her face, and, in spite of the constraints imposed by
the cuffs and harness, her body appeared to be completely relaxed.  Perhaps
the reason for Maria's composure was the presence of Yoko standing bare
breasted at her head.  With her kimono bunched around her waist, Yoko was
lifting Maria's head with her hands and swaying back and forth, caressing
Maria's upturned face with her breasts.  Whenever one of Yoko's nipples
grazed Maria's lips, Yoko would stop her rocking to give Maria time to suck
that nipple deep into her mouth, and she would not resume until Maria had
released her nipple.  I suspect that, as long as she had access to Yoko's
breasts and nipples, some primordial instinct would make Maria feel secure
and prevent her mind from dwelling on the fears that might otherwise have
occupied it.

   The scene I beheld reminded me of our first visit to Sato's studio, the
one on which Yoko had solicitously leaned her unfettered, bare breasts over
Maria's thoroughly bound but equally bare orbs, and I was reluctant to
disturb their blissful state.  Thus, I simply observed the sensuality of
their activity and appreciated its aesthetics.  After several minutes, my
reverie was interrupted by the appearance of Sato.  All business, he hardly
acknowledged my presence and, like a surgeon entering an operating theater,
headed for the table on which he would exercise his skills.  Yoko
immediately withdrew, leaving the stage to her boss.  Given free access to
Maria's front, Sato set to work.  He began by systematically placing pads
to strategically chosen locations all over Maria's front.  On the side of
the pad touching Maria was a thin metal plate which made direct contact
with her skin and would be held in place by an adhesive substance.  On the
outer side was a short electrical connector.  I was struck by the care with
which Sato chose where each pad would end up.  Before attaching a pad, he
would palpate in the vicinity of its eventual destination.  Thus, when he
was placing pads in Maria's armpits and groin, he would search for the spot
where her lymphatic nodes are closest to the surface; when the target was
her abdomen, he would seek out specific muscle groups; and when he turned
his attention to her breasts, his used her fingers to locate her mamMaria
glands.  When he was done, Maria's torso was adorned in a rather pleasing
manner with an array of small white pads that traversed her entire torso in
a symmetric pattern.

   Sato stepped back to contemplate his creation and explain his intent. 
Speaking for Maria's benefit more than my own, he said that he would start
by teaching Maria's muscles to respond to electrical stimulation.  During
this phase, he would use only those electrodes which were attached to her
abdomen.  He anticipated that it would take at least ten minutes for her
muscles to learn how to derive pleasure from their stimulation.  At first
their response would be to clench in an spastic and somewhat painful
attempt of resist what was happening to them.  However, they would soon
learn how to accommodate their stimulation and to contract in unison with
the waves of current passing through them.  At that point, the pain would
recede and be replaced by the pleasure not unlike that of a ballerina who,
after submitting her body to her partner, knows that it is performing in
concert with his.

   Understandably, his explanation had produced a look of considerable
apprehension on Maria's features, a look which Sato chose to ignore. 
Instead, he deftly attached wires to the ten or more electrodes in Maria's
abdominal region.  That done, he turned his attention to the machine from
which the wires ran and started turning knobs.  Shortly thereafter, Maria's
abdominal muscles began to twitch, and as he continued I saw that his
prediction had been correct.  Maria's initial response was to clench every
muscle in her abdomen, and once she had done so, it seemed that she had
lost the ability to unclench them.  Her face was a mask of pure anguish,
and beads of sweat began to emerge from every pore of her body.  Without
asking Sato's permission, I moved to the position at Maria's head that Yoko
had occupied.  Leaning over to bring my face within inches of hers, I asked
if she wanted to abandon this harrowing experiment.  A wan smile of
gratitude appeared on her features as she shook her head and, through
gritted teeth, whispered that she was determined to have her body learn the
lessons that Sato intended to teach it.

   Even as she was whispering these courageous words, I could see that her
body was starting to come to terms with the stimulation that it was
receiving.  The knots of bunched muscle were disappearing and being
replaced by sheets of sinews that ran along sculpted contours from her
pubis to her waist.  At the same time, their initial immobility was being
replaced by rhythmic contractions that produced a subtle but distinct
pattern that displayed both the strength and the distinctly feminine
curvaceousness of her lower body.  I soon realized that Sato's was
orchestrating a symphony for which Maria's abdomen was the orchestra.  By
modulating the current applied to the individual pads, he was creating
waves of stimulation for Maria's muscles to surf.  When he saw that her
tummy had learned how to ride these waves, he began playing her body like a
musical instrument, making changes in the wave pattern to produce
corresponding changing in her undulations.  I was pleased to note that as
her body learned how to adapt, the expression on Maria's face evolved from
one of pain to one of intense concentration.  In fact, she too was staring
at the sensual dance that her abdominal muscles were performing and, in
spite of the toll it was exacting on them, seemed to be appreciating their
performance.

   Not wanting to exhaust her at this early phase, after a few minutes Sato
lowered the current to a level at which Maria's muscles would remain taut
without too much exertion.  Her body, which she had raised so that it ran
like a plank between her shoulders on the table and her legs suspended in
their harness, slumped to a supine position.  However, her rest period was
not one of total relaxation.  Besides the fact that her stomach continued
to respond to the pulsing current applied to it, Sato was taking advantage
of her relatively quiescence by connecting the pads on her breasts and
those in her groin and armpits.  Once those connections were made, he moved
to the bottom of the table, carrying with him a pair of rods.  The first of
these rods was rather short and had a bulb at its end.  Prizing open the
crack between Maria's suspended buttock, he daubed her anus with a generous
dab of ointment before slowly inserting the bulb into her rectum.  The bulb
must have been at least an inch in diameter, but the ointment eased its
passage so that the whole procedure was over quickly and caused Maria
minimal discomfort.  The second rod was of a more intricate design.  The
rod itself was about ten inches long and slightly flexible, but its
daunting feature was a solid looking egg shaped structure at its tip. 
Spreading Maria's labia with the fingers of one hand, he inserted the rod
to the hilt with his other hand.  Because her own secretions were already
in full flow, again this intrusion caused Maria little or no distress until
the egg reached the end of her vaginal channel and came into contact with
her cervix.  She had assumed that, once the rod was embedded, Sato would be
satisfied.  Thus, she was taken aback when he continued manipulating the
rod, shifting the egg until it was firmly lodged at the entrance to her
uterus.  Although I imagine that her uterus had had similar experiences
during gynecological exams and intercourse, I could understand that there
must be a world of difference in her mind between a standard medical
procedure or coitus and what she knew to be the diabolical purpose of
Sato's probing.

   At last satisfied with the position of the egg, Sato leaned back and,
from between her splayed legs, told Maria what was in store for her.  His
plan was to start by activating the rods invading the front and back
entrances to her body.  Based on past experience, he predicted that at
first she would have a hard time coping with the intensity of sensation
that they produced.  Because he wanted to make her concentrate on those
sensations without distraction, he would wait to activate the pads on her
breasts, armpits, and groin until he was confident that she could
accommodate the additional stimulation without diminishing the benefit of
the continuing stimulation of the probes buried deep inside her vagina and
rectum.  After returning to his panel, he picked up a couple of
transmitters, one in each hand.  Pointing the one in his left hand at
Maria's crotch, he used his thumb to slowly turn the dial on that
transmitter.  As he turned further, Maria's eyes and mouth opened wider and
wider.  At the same time, her pelvis rose from the table and her gluteal
muscles contracted in a way that produced deep hallows in her usually lush
buttocks and brought her bald pubis into stark prominence.

   Apparently responding to Maria's distress, Yoko attempted to give her
solace.  Bending over to bring her bare breasts close to Maria's face and
cradling Maria's head in her hands, Yoko tried to console her by assuring
her that she would not only survive but even learn to find pleasure in what
her bowels were being forced to endure.  After planting a loving kiss on
Maria's gaping mouth, Yoko went to the end of the table where Maria's lower
body was suspended in a tense, frozen state of immobility.  Placing a hand
in the hallow on each side of Maria's buttocks, Yoko stroked the rigid
muscles there while urging Maria to try relaxing them.  Whether it was
Yoko's guidance or simply that the spasms in her bowels began to recede, I
had no way of knowing.  Whatever the reason, within a few seconds, as
evidenced by the return of her buttocks to its normal, generously rounded
proportions, I could see that Maria's gluteals had released their grip. 
When this occurred, Yoko transferred her hands to the apex Maria's pubis,
which she gently rubbed with the heel of her palm.

   None of these proceedings escaped Sato's watchful eye.  As soon as he
saw that Maria was no longer in distress, he began turning the dial in his
right hand.  I had anticipated that the activation of her vaginal probe
would be an even more traumatic experience for Maria than that of the one
in her rectum.  Thus, I was surprised when quite the opposite turned out to
be the case.  As Sato increased the strength of the current, Maria's body
rose in an arch supported at one end by her shoulders on the table and the
other by the harness on her legs.  However this time, instead of the
uncontrolled spasm that the bulb in her bowels had caused, her rise was
wonderfully graceful.  Unable to articulate her emotions, Maria closed her
eyes and emitted a sequence of guttural moans which could only be
interpreted as expressions of incomparable ecstasy, albeit an ecstasy
resulting from an nearly intolerable mixture of pleasure and pain.

   For several minutes, Maria hardly moved.  During this period, Yoko
continued her stroking of Maria's mons and extended it to include the
crease between Maria's labia through which Sato's electrode protruded. 
With great delicacy, Yoko spread Maria's labia to expose her clitoris. 
After teasing that nub of erectile tissue from its hiding place, Yoko ran a
finger back and forth over its surface.  It was clear from the expression
on Maria's face that she was acutely aware of Yoko's activity, but her body
did not seem to be responding.  Thus, I was unprepared when, without
warning, she thrust her pelvis in Yoko's direction and rotated her hips in
a manner that left no doubt about its meaning.  In spite of the gadgets
mounted on and inside her body, not to mention the presence of Sato and
Yoko, she was in the throes of an orgasm that consumed her entire being and
made her oblivious to all else.

   When her orgasm subsided, Maria's lowered her body back to the table. 
Looking down at her panting frame, Sato smiled and congratulated her on
what he predicted to be only the first of several orgasms that she would
have before her visit was over.  While she was still recovering, he went
back to his panel and activated the pads which he had not as yet brought
into play.  Beginning with the ones in her armpits and groin, he slowly
increased the current, producing a distinct twitching in those regions. 
His next target was her breasts.  Initially, the stimulation coming from
those pads seemed to intended to provide unalloyed pleasure to which Maria
breasts and nipples responded by swelling a little and acquiring a darker
hue.  However, she soon learned that there was a price to pay for her
pleasure.  Namely, each of the pads mounted on the soft undersides of her
breasts was a miniature spark plug that, at unpredictable times,
discharged, imparting a shock to the network mamMaria ducts just below the
surface of the breast to which it was attached.  Although these shocks were
not severe, they were sufficient to keep Maria in a constant state of
tension, wondering when and to which breast the next shock would delivered.

   While Sato was making his preparations for Maria's next experience,
Yoko, after covering her nakedness by retrieving the upper portion of her
kimono, left the room.  When she returned, she was accompanied by three
other members of Sato's staff, two young women and a young man.  These new
arrivals arranged themselves in a circle around the table on which Maria
was struggling to cope with the recent changes that Sato had made to her
circuitry.  When she became cognizant of their presence, she turned her
head toward Sato to ask why they were there.  Sato answered by telling her
that there were two reasons for their presence.  First, he wanted to
deprive her of her last vestiges of modesty.  Secondly, like a master
craftsman who is responsible for the training of apprentices, he wanted
them to learn how to manipulate the female anatomy in ways that give
pleasure to both her audience and, though at a high price, to the subject
herself.  He then turned to his young disciples and described what they
would be seeing.  By carefully modulating the charge being sent to the
devises in Maria's rectum and vagina, he would induce her uterus to
contract in much the same way as it would during partuition.  Although no
fetus was involved, these contractions would grow in intensity and exact an
enormous toll on both her uterus itself and the ligaments supporting it. 
When this occurred, he would have them examine and palpate Maria's writhing
abdomen so that they would know what muscles were involved and marvel at
the strength of the structure out of which they had entered the world.

   Having finished his lecture, Sato turned his attention to the tools at
his disposal.  He began by increasing the current flowing to the pads on
Maria's belly, bringing it to approximately the same level as it had been
before he introduced the rods into her nether orifices.  When her stomach
muscles were once again dancing to his tune, he armed himself with his
transmitters, moved to a position at the end of the table from which he
would have an unobstructed view of Maria's vulva, and started rotating the
dials with his thumbs.  Like a robot under its operator's control, Maria's
body re-assumed the arched position in which she had had her orgasm. 
However, this time, the situation was entirely different.  For one thing,
Yoko had been replaced by strangers, none of whom was likely to provide her
the comforting service Yoko had.  Further, Sato had no intention of letting
her off as lightly as he did last time.  After getting the dials set with
his thumbs, he moved his right hand so that his forefinger rested on a
button that he had not as yet employed.  The instant that his finger
depressed this button, Maria emitted a heartrending cry followed by wild
gyration of her hips, gyrations which continued well after Sato released
the button.

   By way of explanation for what they had just witnessed, Sato told his
young assistants about the egg shaped object lodged at the entrance to
Maria's uterus and the shock that Maria's uterus would receive from that
object each time that he depressed the button on his transmitter.  He
predicted that it would require at least five or six shocks to induce
Maria's uterus to contract in the way he wanted it to and asked that they
be patient.  Without concern for Maria's suffering, he depressed the button
repeatedly, each time eliciting a plea for clemency from Maria.  However,
her pleas fell on deaf ears.  Sato had a goal, and, if achieving that goal
required Maria to suffer, then suffer she would.  Watching his determined
face, I was reminded of a man trying to start a recalcitrant automobile:
the button being the ignition key and Maria's uterus being the balky
engine. Finally, the engine caught, and, once it did, it required only
occasional encouragement to keep running.

   Although I commiserated with Maria's plight, I could not help admiring
the performance to which she was treating her audience.  A steady flow of
undulating waves passed over her taut lower belly.  At the same time, her
harnessed legs spread to reveal the changes that were taking between them.
Particularly dramatic was the swelling of the entire region around her
vulva, which, bathed in copious secretions, resembled an overripe fruit. 
So overwhelmed was she by her ordeal that I could not tell if she was aware
of the examination that Sato's students were making of her.  Once the
rhythm of her contractions was well established, they took turns running
their hands over her undulating belly, and one of the young women extended
her exploration to include the intricacies of the obscenely exposed layers
of pulsating flesh at the entrance to her vagina.

   I am not sure exactly how long Sato's anatomy class lasted, but he
eventually dismissed his students and reduced the current being applied to
Maria's body.  After the students had left, he made a few more adjustments
and announced that he had accomplished his mission and would leave Maria in
Yoko and my hands.  Being uncertain what was expected of us once he was
gone, I was relieved to learn that Yoko did not share my uncertainty.  As
soon as the door closed behind Sato, she disrobed and climbed onto the
table.  Straddling the arch formed by Maria's body, she lowered her buttock
until it made contact with Maria's belly.  Once it had, she slowly
transferred her weight to Maria, thereby gently guiding Maria's torso back
to the table top.  When Maria was back on the table, Yoko leaned forward so
that her pear shaped breasts hovered over Maria's.  By rocking her body,
Yoko set her own breasts in motion, maintaining them at a height so that
only her nipples touched the body below them.

   Maria had recovered sufficiently to be conscious of and grateful for the
comfort Yoko was affording her.  However, I doubt if she was able to
appreciate how sensual and beautiful was the image that she and Yoko were
creating.  Crouched as she was over Maria, Yoko presented me with a example
of femininity which, considering her slim frame, was remarkably sumptuous.
Her hips flared out from her wasp-like waist, and the firm cones of her
breasts swung back and forth in what looked to me like an seductive
invitation to have someone arrest their motion.  Beneath her, Maria's body
was equally enticing, but for entirely different reasons.  Ironically,
whereas the position of Yoko's diminutive frame maximized her feminine
attributes, Maria's much more generous contours were minimized by a
combination of her supine position and the visible strain that her
incessant stimulation was putting on them.  As a result, the curvaceous
Maria might have been mistaken for a female bodybuilder, whereas no such
mistake was possible when looking at the rounded contours of the otherwise
tightly strung Yoko.

   After a while, Yoko sat back, carefully positioning her buttock on
Maria's belly to avoid the pads there.  She then removed the pad that had
been delivering the shocks to the underside of Maria's left breast and
re-attached it, this time directly to the areola on that breast.  Once she
had repeated the same process on the other side, she leaned forward again,
pressing her own pert breasts against flattened Maria's ones and sealing
the fronts of their bodies together.  Yoko then told me how to increase the
frequency and intensity of the shocks, shocks which would now be sent
directly to the most sensitive spot on each of Maria's breasts.  As soon as
I had followed her instructions, a renewed tension was evident in Maria's
body.  Not only were her nipples were being zapped several times a minute,
but between discharges her anticipating of the next shock meant that she
was in a constant state anxiety.

   Yoko's plans were unclear to me until I overheard what she was
whispering to Maria.  Her goal was to force Maria to have an orgasm without
lessoning the tension that gripped her body.  According to Yoko, Maria's
body would struggle to reconcile the pleasurable sensations she would be
giving it with the painful ones that the electrodes were delivering, a
reconciliation which, when it occurred, would result in Maria being unable
to distinguish between the two.  At that point, Yoko promised Maria that
she would experience an orgasm that would make her grateful for the
suffering she was being forced to endure, suffering that, in the end, had
contributed to the intensity of her experience.

   Yoko next reversed the direction in which her body covered Maria's. 
Thus, her buttock now assumed the post that her breasts had occupied and
her head was supported in the V between Maria's thighs.  Tipping her head
forward, Yoko brought her tongue into action.  I had never imagined that
witnessing the act of cullingus could be a source of erotic, much less
aesthetic, pleasure.  Indeed, I had always found the thought repugnant. 
Nonetheless, the sight of Yoko perched with her haunches hovering over
Maria's breasts and using her educated tongue to give Maria's painfully
taut body pleasure was an image of enormous erotic and aesthetic appeal.  I
was particularly captivated by the way that Maria's belly was responding.
Instead of holding it rigidly static, she was moving it in the same
sensuous manner that she does when we have intercourse.  The fact that her
abdominal muscles remained clenched and clearly visible only increased the
eroticism of the image by emphasizing the depth of her submission to the
demands of her libido.

   When Yoko sensed that Maria was approaching a climax, she lifted her
head long enough to tell me to increase the strength of the current going
to Maria's vagina and rectum, thereby prolonging the time that Maria would
have to spend precariously suspended between heaven and hell.  Throughout
that time, her body was continuously wracked by convulsions that traveled
in waves, starting at her head and progressing down her torso until they
culminated in powerful bucking thrusts of her pelvis.

   Maria had to wait at least ten minutes before she was granted the sexual
relief for which she had been valiantly striving, but, when it at last
came, the pleasure she derived more than compensated for the delay in its
arrival.  Nonetheless, by the time that the final convulsion had run its
course, she was gasping for air, dripping with sweat, and utterly depleted.
Knowing that they had done their work, Yoko had me switch off the current
to all the electrodes attached to Maria.  Once I had complied, Yoko again
reversed directions and hugged her body to Maria's, using Maria's sweat to
seal them together, a seal that she did not break until Maria's breathing
returned to normal.

   When Yoko dismounted from the table, she fetched a couple of bath towels
and bade me help her wipe away the pools of sweat in which Maria was
bathed. In the process, we removed most of all the pads on Maria's front,
but Yoko told me not to disturb to rods in her vagina and rectum.  Once
Maria's skin was dry, Yoko first sprinkled it with a fragrant powder. 
After spreading the powder into a smooth, even film, she poured body oil on
top and massaged the mixture deep into Maria's receptive pores.  Since she
performed all these services while completely nude, I had another
opportunity to appreciate her trim yet invitingly feminine figure, a figure
that, under other circumstances, I would have been sorely tempted to
explore.

   However, it was really Maria to whom I was beholden.  She had allowed me
to witness the harrowing ordeal to which she had submitted herself for our
mutual pleasure.  Thus I was glad to see Yoko collect her kimono and
prepare to depart.  On her way out, she stopped to give Maria a warm kiss,
and at the door she turned to tell me that I had in Maria a remarkable
woman who deserved to be rewarded for the sacrifices that she had been
making for our benefit..

   I was more than ready to follow Yoko's instructions, but I was somewhat
at a loss as how to proceed.  My role thus far had been that of spectator,
and, although I had not played active part, I had been in a continuous
state of extreme excitement for nearly an hour.  My instinct was to drop my
pants and, as soon as possible, embed my painfully erect penis inside Maria
proffered body.  However, my desire to obey my instincts was tempered by my
recognition of Maria's understandable exhaustion.  Thus, I first went to
the end of the table that supported Maria's head and bent over to ask what
form she would like her reward to take.  Groggy, like someone emerging from
anesthesia, she smiled and said what she would like best is to have the
surrogate penis in her vagina replaced by a real one.  Happy to oblige, I
went to the other end of the table and removed the electrode that my penis
would be replacing.  I also intended to remove the one invading her rectum
and unharness on her legs, but, seeing my intentions, Maria told me to
stop. I next took off all my clothes, climbed onto the panel over which
Maria's pelvis continued to dangle.  I was prepared to enter her, but just
as I was about to, Maria again interrupted me and asked that I hand her the
transmitter that controlled the bulb which was still in her rectum.  When I
expressed surprise, she gave me a sly smile and explained that she wanted
to have me experience what it was like to have an electric shock applied to
an erogenous zone.  Although I would not get the full effect, she was
confident that some of the electricity would penetrate to my penis through
the thin wall separating her rectum from her vagina.

   At last free to satisfy the craving that had been steadily building ever
since the evening before, I drove my rampant penis deep into Maria's
welcoming vagina.  Within seconds I was ready to ejaculate, but when she
felt my penis pulse in preparation for ejaculation, Maria turned the button
on the transmitter so that it released a jolting shock in her rectum.  As
she had predicted, her perinial membrane afforded my penis only minimal
protection, with the result that I was temporarily denied my much
anticipated relief.  Clearly enjoying my dismay, Maria told me that she
intended to delay my gratification for as long as she could so that I would
learn about the bitter sweet frustration of having someone else in control
of the most vulnerable part of my body.  True to her words, Maria kept me
on the verge of orgasm for a full five minutes, and, when I was finally
able to ejaculate, she made me do so while the bulb in her rectum was on
full power.

   Once I had recovered a little, I returned to my feet and released Maria
from her bonds.  As had been the case at the end of our previous visit to
Sato's studio, neither of us was inclined to indulge in light banter.  We
took advantage of the shower in the adjoining bathroom, dressed quickly,
and hailed a taxi to take us to the airport.  At the departure gate, we
stood for quite a while simply staring into each others eyes.  Finally,
Maria nodded her head, whispered that she had no regrets, and headed for
her plane.
