Mutually Administered Self-Improvement
 
                      by anon1040

This is another installment of the tale which began with "A Brief
Affair" and continued in "A Lesson in Yoga."
                                                                                                                                                   
After my second visit to her apartment, it was clear to both Liu and
me that our relationship had entered a new phase.  Of course, the fact
that we had had sexual intercourse represented a dramatic turning
point.  However, the act of intercourse itself was maybe less
important than the physical intimacy which preceded it.  By allowing
me to watch her perform her yoga exercises. Liu had revealed an aspect
of her existence in which the physical was inextricably related to the
spiritual.  Having followed her performance by manipulating my body so
that I would learn first hand the demands which she had been putting
on her body, she had made me appreciate the intensity of her
experience and the sense of vulnerability she must have felt while
doing them.

During our conversations about how, or even if, we should proceed, it
became increasingly clear to me that Liu had been as affected as I by
what had transpired in her apartment.  She had obviously enjoyed
having me witness the discipline required by her yoga exercises.  In
addition, she had found it exciting to impose that discipline on
me. What she had not determined is how or whether it would be possible
to reproduce that pleasure and excitement.  She was reluctant to have
us become conventional lovers who simply relieved their carnal desires
with an occasional coupling, but she had been unable to come up with a
satisfactory alternative.  Thinking that I understood what she was
seeking, I made a suggestion.

"You have made it obvious that you want to find a way for us to
continue the exploration of each others bodies without our becoming
lovers in the usual sense. Instead, you seem to have in mind a kind of
intimacy which derives from an intimate, but not explicitly sexual,
familiarity with each others body.  One approach to achieving such a
familiarity might be for each of us to take responsibility for the
transformation of some portion of the other's anatomy. For example, I
would like to develop your abdominal muscles so that your lower belly
would acquire a more pronounced contour.  I do not know exactly how I
would go about producing that contour, but I would expect your
unquestioning complicity in whatever program I tried.  Similarly, when
you had decided how you would like to transform some part of my body,
I would concede to you the right to apply methods of your own
choosing."

After hearing my proposal, Liu took her time before responding. The
look on her face indicated that I had struck a chord with her own
ruminations, but her body language indicated that she was having
trouble coming to terms with the possibility that her fantasies might
become realities.  When she finally spoke, her words reflected the
ambivalence that she was feeling.

"I will not deny that your idea appeals to me and that it is not far
from ideas which I have had myself.  At the same time, I will not deny
that there are elements of your proposal that disturb me.  I very much
enjoyed pushing you beyond the limits which you thought your body
could tolerate, and I have wondered whether I would like someone to so
something similar to me.  On the other hand, heretofore, I have always
thought about such matters in the abstract and have never confronted
the question of actually submitting myself in that way to another
person's control.  One of the reasons why I choose yoga over other
forms of athletics is that I like the sense of control which yoga
requires me to have over my own body, but I am not at all sure that I
want to share that control with somebody else.  I realize that it is
inconsistent for me to enjoy exercising such control over you and
hesitate to grant you similar control over me, but consistency is not
to be expected in connection with one's emotional life.  Thus, I am
not rejecting your proposal, but I am asking for some time to consider
it."

I could not but admire Liu's response.  I did not want her to accept
my proposal frivolously, and so I was glad to know that her answer
would be given only after she had thought about its consequences
seriously.  Thus, I decided that it would be best not to rush her and
to wait for her to bring up the subject when she had reached a her
decision.

A few days later, Liu came to my office.  After locking the door, she
approached me and, standing with her legs firmly pressed against my
desk, defiantly raised her blouse.  With one hand clutching the blouse
just below her breasts, she used the other to lower her panties until
her bare belly was exposed all the way from the bottom of her bra to
the upper edge of her pubic hair.

"I gather that this is the portion of my anatomy which you think needs
to be improved.  Although I am not sure how you plan to improve it, I
am ready to have you try.  In return, I will endeavor to improve the
part of your body on which I worked the last time you visited
me. Namely, your legs, and particularly your groin, are extremely
inflexible.  My goal is to loosen the ligaments and tendons in that
region so that you will be able to assume the sort position which I
will now demonstrate."

Moving back from my desk, Liu raised her skirt lowered herself to the
floor.  Lying on her back with her skirt bunched at her waist, she
first raised her legs until they were perpendicular to the floor and
then began to spread them.  As they spread, the tendons along her
inner thighs became more prominent and, by the time that her feet were
within inches of the floor, it looked as if her hips had spread and
the ball joints in her pelvis had partially opened to accommodate the
stress to which she was subjecting them.  When her ankles were grazing
the floor, she grabbed them with her hands so that, apart from her
neck and head, her body formed a slightly skewed trapezoid.  Looking
at me through her splayed legs, she said,

"I doubt if will be able to reproduce this pose, few men ever can.
Nonetheless, your body can be taught to make a close approximation of
it, and I look forward to being its teacher."

Having delivered her acceptance of my proposal in such a dramatic
fashion, there was no point in Liu's delaying her departure.  Thus,
after telling me to come to her apartment at 9AM the following
Saturday, she rose, put her clothes back in order, and left my office.

It was with considerable anxiety that I made my way to my appointment
on Saturday morning.  I had only a vague idea how I would proceed with
the training of Liu's tummy, and I had no idea what she had planned
for my groin.  When she let me in, she was wearing a two piece leotard
which left her midriff completely bare between a scant halter and an
even more scant strip of cloth which covered but hardly hid her pubis.
Otherwise, except the bow which held her hair in a pigtail over one
shoulder, she wore nothing else.  As on my previous visit, all the
furniture in her living room had been shoved aside, leaving ample
space in the middle for the foam mat on which she had first
demonstrated and then introduced me to the meaning of disciplined
exercise.

Once we were in the living room, Liu stood directly in front of me
and, without a word, began undressing me.  After removing each piece
of clothing, she meticulously folded it before placing it on a neat
little pile which she made in one corner of the room.  Having divested
me of everything else, she stopped when I was down to my underpants
and led me to the mat.  There, in an unbroken, flowing motion, she
lowered herself into a sitting position, which she then transformed
into a classic yoga pose with her feet resting in the crevice between
her calves and thighs. Bidding me to follow suit, she clasped my hands
and solicitously guided me into an awkward mirror image of herself.

"If you have no objections, I would like to begin by discussing how
you think that you can give my stomach the shape which you want it to
have.  You should know that, although my yoga routine helps me keep my
abdominal muscles toned, it does not aim to strengthen them.  On the
other hand, as a youngster in China, I did do exercises designed to
make them strong.  In fact, in order to be eligible to compete for a
place in one of the better schools, a girl must be able to do
forty-two situps in a minute.  Thus, at age eighteen, my abdominal
muscles were much more developed than they are today.  On the other
hand, even at their strongest, they never produced more than a gentle
curve in my otherwise concave belly.  Of course, I have matured in the
meantime, and so renewed training might now result in a more
aesthetically pleasing result."

Grateful for the background information which she had provided, I
admitted my uncertainty.

"I do not know how, or even if, it is possible to significantly alter
the shape of your stomach.  Thus, I must proceed by a method of
experimentation.  My intuition tells me that adding bulk to your
abdominal muscles will enhance the shape of your belly, and so my
efforts will be directed in that direction.  Based on what you just
told me, I will begin by bringing your abdominal muscles back to the
strength that they had when you competed to enter an elite school in
China.  By the time they have, I assume that I will have thought of
new goals for them to achieve.  In any event, I anticipate that, for
some time to come, you will be continuously aware of the demands which
I will be making on your tummy, a fact which will be a source of
pleasure to me and, I hope, pride to you."

I watched with interest my words, especially the somewhat ominous
concluding ones, register on Liu's features.  The idea of re-engaging
in the rigorous exercise routine of her youth brought back memories
which were obviously not altogether happy, and she grimaced when I
mentioned the residual soreness which I wanted her to experience.
However, once she had heard me out, she did not hesitate long before
telling her plans for me.

"Your training program will be somewhat different from mine.  My guess
is that mine will consist of relatively brief periods during which my
muscles undergo an arduous workout.  To accomplish what I have in mind
for you will require more subtle methods.  Stretching tendons and
ligaments is a very different goal from building muscles.  At no time
will I have to make your muscles work as hard as you will make mine.
On the other hand, I will force you to continue for much longer
periods.  I will employ various techniques to relieve your stress and
tedium, but I have no intention of coddling you, and, just as you
assured me that I would have residual effects to remind me of my
travail, so I can assure you that you will not quickly forget yours."

Having learned what to expect, the next step was to decide how to
proceed.  Taking into account the difference in duration of our
routines, we agreed that it made more sense for me to exercise Liu's
stomach before she worked on my legs.  Because her apartment was very
warm and perspiration was already glistening on her body, I decided
that there was no need for preliminaries and asked her to show me the
abdominal exercises with which she had prepared for her entrance exam
in China.  After scouting back a few feet, she lay back on the mat,
bent her legs, and told me to hold her feet flat.  She then clasped
her hands behind her neck and performed a sequence of rapid sit-ups,
each time bringing her chest to her knees before immediately dropping
back to the mat.  Because each repetition took only a couple of
seconds, it was easy for me to believe Liu's claim that at one time
she had been able to perform forty-two in a minute.  Indeed, speed
seemed to have been the primary goal of this exercise, but it was not
mine. Thus, after she had completed about twenty, I told her to stop.

"I can understand why such sit-ups were good preparation for your
exam, but they are not well suited for my purposes.  You are no longer
in a race against the clock.  The clock will still play a role, but
its role will be different.  Namely, it will measure the duration
instead to the speed of each sit-up.  Thus, I now want you to raise
yourself off the mat and keep yourself raised for as long as you
can. I think that you should be able to stay up for at least half a
minute."

Liu winced when she heard my final sentence, but bravely followed my
instructions to the letter.  As I had predicted, half a minute had
passed before she collapsed back onto the map.  In the response to the
demands being made on it, her lower belly bulged throughout her
sit-up, and during the final few seconds began to tremble.  While I
waited for her to regain her breath, I warned her that she would have
to perform nine more such sit-ups, each one lasting half a minute.  To
assuage the fear resulting from my warning, I leaned forward and
gently rubbed her tummy, savoring the way it swelled and contracted as
she gasped for air.  By the time that she had completed her
assignment, Liu's abdominal muscles were utterly exhausted. In search
of comfort, she had rolled over on her side and hugged her bent legs
to her heaving chest.  Even though her face was pressed against her
knees, when I knelt by her side I could see that there were tears in
her eyes.  Moved by the pitiful sight of her depleted body and hoping
that she would interpret it as a compensation for her distress, I ran
my hand over the damp strip of cloth covering her vulva.  Running my
fingers around its periphery and along the crevice bisecting this
mound, I commiserated with Liu.

"In spite of my warnings, you had no idea how hard I would make your
stomach work. Although I will increase both the difficulty and
duration of your exercises, I believe that, even if they are not
easier for you to bear, in time you will have an easier time bearing
them.  Of course, for the next few days your abdominal muscles will be
very much on your mind, but, by the time that I renew their training,
they will be ready to do so.  In any event, you can take satisfaction
from the opportunity which you will have now to take revenge."

Liu's spirits improved when I reminded her of this opportunity, and
she soon recovered sufficiently to act on it.  Resuming her seated
position in front of me, she outlined her program.

"As a first step, I will stretch your legs in the same way I did
before.  Once they have again become accustomed to that, I will
introduce them to a new exercise, one which will last quite a while
and require considerable courage for you to tolerate. During that
second phase of your training, I will offer you the same sort of
distraction which you have just been providing me, but I predict that
you will be bowed legged for a while."

After I spread my legs, just as she had the last time, Liu braced her
feet against my ankles, took a firm grip on my wrists, and leaned back
until I my chin nearly touched the apex of her pelvis and my tendons
in my groin were standing out along my inner thigh and in my groin.
This time she rocked back and forth, each time drawing me closer to
her mons and forcing my legs further apart.  With a less than kind
smile on her face, Liu watched the torment recorded on my face and
warned me that there was worse to come.  When she at last released my
hands, I could tell that she had indeed stretched all the connective
tissue in my upper legs and groin and that, as a consequence, my legs
were more limber than when she began.  Leaving me, bathed in my own
sweat, to catch my breath, Liu rose and told me to wait while she
fetched a piece of equipment.  She returned shortly thereafter
carrying what looked like one of those sturdy canvas staps which one
sees securing large pieces of luggage.  Kneeling, she folded back the
mat at its middle and ran the belt beneath before dropping the mat on
top of it.  After making sure that the belt was symmetrically placed,
she had me lie on my back with my pelvis resting on the mat along the
line under which the strap passed.

I had noticed that, about a foot from each end of the belt, were loops
held in place by rather sophisticated looking turn buckles.  I assumed
that my legs were destined to end up attached to these loops, but,
until Liu installed them, I did not appreciate just how much control
they would afford her.  Thus, when she fastened the loops to my legs
just above my ankle, I was more curious than concerned about their
purpose.  However, when she raised my legs perpendicular to my body
and began adjusting the turn buckles, I quickly realized that the
strap gave her enormous mechanical advantage and that, if she wished,
she could probably rend my legs from my hips. Fortunately, even if she
was not averse to paying me back for the pain which I had inflicted on
her, she is not basically vindictive.  Thus she stopped turning the
buckles once she saw that further spreading could cause
damage. Nonetheless, she did not stop until the pain in my groin was
so significant that I had begun to doubt my ability to stand it.
Looking down at me, she seemed pleased with her handiwork and
complimented me on my fortitude.

"As I told you last time, I know the pain which you are feeling.  When
I was young, my parents thought that I should study ballet, and so I
attended ballet school twice a week until I left China.  In China,
ballet masters assert absolute control over their students and show
little mercy.  Thus, when it comes to training a young girl's legs,
old fashioned methods are applied.  For half an hour each class we
were lined up at the barre.  So long as the master deemed that we were
showing sufficient diligence, we were left to stretch our own legs.
But if he saw one of us flagging, he would take a position on the
opposite side of the barre, grab the malingerer's raised leg around
the calf and pull with all his might.  In total, I must have spent
several hours with my crotch mashed on the upper edge of the barre and
one leg or the other feeling as if it were being ripped from my body.
By comparison, your suffering is mild, and you should be grateful to
not be a young girl at the mercy of a Chinese ballet master."

After she had delivered this cold comfort, she dropped to her knees,
placed a hand on each of my inner thighs and began delivering comfort
more to my liking.  Much to my surprise, her ministrations not only
gave comfort to my splayed limbs but also lit a flame in my libido.
As she stroked her hands over the distended ligaments in the vicinity
of my crotch, I began to develop an erection which soon resulted in
the appearance of my penis through the fly of my underpants.
Delighted, Liu abandoned by my thighs and cupped her hands around my
penis.  Alternating her attention between its rampant shaft and its
swollen glans, she caressed it with expertise while commenting my
plight.

"Although you must be frustrated and confused by being simultaneously
helpless and sexually aroused, you have to admit that being teased in
this manner is preferable to situation in which my erogenous zones
found themselves while the ballet master was stretching my legs at the
barre.  Being rather short, I usually ended up literally suspended
over the barre with both feet off the ground and my whole weight
bearing down on my pubis.  Your legs and groin are suffering, but your
genitals are not.  Because this is the first time that I have
stretched you in this manner, I will release you after fifteen
minutes.  Between now and then, you too will experience a kind of
suspension, but yours will be of an entirely different nature from
that which I had to endure.  You will be suspended between your desire
for relief from the pain in your groin and your desire to consumate
the sexual pleasure which your groin is earning for you.  When, in the
future, I will stretch you for longer and longer periods of time, I
will have to devise more ingenious methods to keep you aroused."

Delivering on her promise, Liu succeeded in keeping me sufficiently
sexually excited that I was occasionally able to ignore the signals
coming from my legs and groin.  In addition, these signals caused me
less distress as my ligaments and tendons became more accustomed to
being lengthened.  Thus it was easier for me to tolerate my fifteen
minutes under Liu's tutelage than it might have been.  In fact, when
she finally relented and freed my legs, it was unclear to me whether
it was my legs or rock hard penis which was the greater source of
discomfort.  Before I had time to decide, Liu crouched over my pelvis
and lowered herself onto my penis.  All memories of my recent ordeal
vanished until I tried to get up after she had satisfied our mutual
need and thoroughly drained me.

For several days following my visit to Liu, all the musculature in my
groin complained about the treatment which it had received.  When my
wife commented on my awkward gait, I made up a lame story about
accidentally slipping while getting out of my shower.  My resentment
was appeased by the evidence that Liu too was suffering from the
aftereffects of my visit.  She performed all her movements, and
especially those requiring her stomach muscles, gingerly.  We observed
each but hardly communicated until, on the following Friday, she came
to my office to find out whether I had had enough or wanted to resume
my training.  After asking her the same question and receiving an
affirmative, albeit hesitant, answer, I told her to expect me at her
apartment the following morning.

It is one thing to submit oneself to an ordeal for the first time and
quite another thing to do so again.  The first time one's courage is
bolstered by the excitement of the unknown, but thereafter the novelty
has warn off and one already knows what fate awaits you.  Thus it is
not surprising that Liu and I had reservations about putting ourselves
again at the others' mercy.  After I had undressed and joined Liu on
the mat, I attempted to raise her enthusiasm by first examining her
belly to check for signs of progress toward the goal which I had set
for her.  For the purposes of her examination, I had her display her
tummy for me by sitting on her haunches and leaning back so that her
tummy was arched into a bridge anchored to the mat by her shoulders
and buttock.  In this position, Liu's belly was ideally presented for
inspection, and I spent several minutes tracing my fingers along the
contours of its surface and palpating the tightly drawn muscles
beneath.  I did not expect dramatic changes to its shape, and I did
not find any.  On the other hand, I did sense that there was a subtle
increase in the curvature of her belly and was pleased to note that,
even in this position, it no longer receded as deeply into her pelvic
girdle.  After completing my inspection, I congratulated Liu on her
progress.

As distinguished from her, I had not introduced any equipment into
Liu's first training routine.  Thinking that this omission had been a
mistake, this time I had brought along a medicine ball of the sort
often recommended for abdominal exercises.  Telling her to remain as
she was, I rose to fetch the ball.  When I returned, standing with my
feet in the V between her bent legs, I explained the initial role that
the medicine ball would play.

"The purpose of this exercise is to make you keep your abdominal
muscles hard even though you are not calling on them to perform any
particular task.  The role of the ball is to provide motivation.
Namely, the ball weighs about fifteen pounds, and I will hold it
suspended over your tummy.  Every once in a while, I will drop the
ball so that falls in the depression created by your navel. You are to
cup your hands on either side of your stomach so that you can catch
the ball when it strikes your tummy.  Catching it will be made more
difficult by the fact that, in order to prevent you from knowing when
or from what height the ball is headed toward its target, you are
required to shut your eyes.  I think that you will find this exercise
less arduous than doing sit-ups, but I am confident that it will help
you learn to keep your stomach presented to its best advantage."

Dutifully, Liu closed her eyes, placed her hands on either side of her
bellybutton so that they formed a little barrier, and clenched her
stomach muscles.  In part because it was clear that Liu was making a
concerted effort and in part because I was loath to disrupt the
aesthetic consequences of her effort, I held my fire for a couple of
minutes.  However, when at last I perceived a slight diminution in the
rigidity of her muscles, I did drop the ball. It landed on its target
with a loud splat and elicited an equally loud gasp from Liu's lips.
I let it rest there for a couple of seconds before retrieving it.
When I resumed my watch, I was pleased to note that its impact had
encouraged Liu to renew her efforts and was amused by the pinkish
flush circling her navel.

I continued this relatively benign persecution of Liu's tummy for
about ten minutes. Having absorbed the impact of the ball a total of
five times, the region around her bellybutton was no longer pink: it
had become a livid red.  My original intention had been to have her
immediately do a set of sit-ups, but, for the sake of variety, I chose
to continue with the medicine ball for a while.  Thus, once she had
recovered her breath and was sitting on the mat, I told Liu to balance
herself on her buttock with her feet and chest lifted off the floor.
I then handed her the ball and told her to pass it from side to side
without allowing any part of her body, other than her buttock, touch
the floor.  After she had successfully figured out how to follow these
instructions, I moved behind her, undid the strap of her halter, and
cupped my hands around her now exposed breasts.  Working in unison
with the shifting ball, I gently squeezed and teased the nipple of
whichever breast the twisting of her body was making more available.
Although Liu's tummy was suffering, she persevered until, after she
had been at it for three minutes, I allowed her stop.  Exhausted, she
dropped the ball, lowered her legs, and slumped back, but I refused
her the relief which her abdominal muscles craved.  Instead, I had her
immediately bend her legs and perform sit-ups of the arduous sort
which I had taught her about last time, this time I making her do
fifteen.

It took Liu some time to recover from the workout through which I had
put her. However, as soon as she had, she was intent on taking her
revenge.  She began, as she had the last time, by stretching my legs
by placing her feet against my ankles and pulling forward as she
leaned back.  She then attached the strap to my legs and levered my
legs apart, this time making sure that my feet were half a foot closer
to the floor than they had been when she stretched them before.
Ignoring my moans of protest, she rose and stood so that she was
framed by the V of my splayed legs, She then divested herself of what
remained of her scant clothing to reveal her body whose skin glistened
with sweat from her recent workout.  Fixing her eyes on mine, Liu
brought her arms forward and placed her palms together as if she were
praying.  With her wrists just below her breasts and her fingers
partially hidden in the cleavage between her breasts, she made a
alluring image of femininity, one which was simultaneously beguilingly
sensual and yet dauntingly composed.  From that position, she flowed
through a sequence of yoga poses.

In spite of the pain in my groin and the fact that she was responsible
for causing it, I was mesmerized by Liu's performance.  There was
something deeply erotic about the contrast between the serenity of the
expression on her face and the blatant sexuality of her movements, and
her role in my pain only enhanced my susceptibility to her charms.  At
one point she lowered herself to the mat, lay on her back, and spread
her legs in the way she had in my office.  Lifting her head high
enough for me to see her face through my and her own spread legs, she
informed me that there were twenty minutes left in the half hour that
I would remain stretched.  By then my ligaments and tendons had
loosened, and my pain had receded to a tolerable level.  Nonetheless,
I was taken aback by the news that I would have to tolerate it for
twice as long as I already had.  Perhaps in response to my look of
distress, Liu rose from her supine position and knelt just behind my
raised legs.  Placing a hand on either side, she began palpating the
sinews along my inner thighs and pelvis.  At first I thought that she
intended to provide me some comfort, but I soon realized that her real
purpose was to assess the progress which I had made. Of particular
interest to her was the extent to which the sockets in my hips had
opened, and for this purpose she probed the tendons and ligaments
which attach my legs to my pelvis.  With clinical detachment, she
conducted her examination with skill and caused me less discomfort
than I would have guessed such an intrusive procedure would entail.
After completing her investigation, she leaned back and reported her
findings.

"I am pleased by your progress.  The ligaments which hold the ball
joints at the top of your femurs in the sockets of your pelvis have
stretched enough to afford your legs greater mobility.  Women's hips
are made so that their sockets are further on the sides and quite
easily opened.  Men's hips are narrower and their sockets are less
accessible, but, as your body is now demonstrating, they can
nonetheless be prised open.  Having gone to the trouble of getting
yours open, I would be remiss to not take advantage of their newly
found flexibility. and so I, before I release you I will try to think
of an appropriate way to use it."

Having given me her diagnosis, she stood up again and resumed her yoga
exercises. This time she balanced on one leg and raised the other to
the back until she could clasp it by the ankle.  She then drew the
raised leg up while bending her torso back so that her entire upper
body was arched into a circle mounted on a single pedestal.  As I had
been when she first performed for me, I was struck by her resemblance
to a Henry Moore statue and could not but admire the discipline
required to assume and maintain this resemblance.  She held this pose
for nearly a full minute, giving me ample time to appreciate the
resemblance of her sensuous body to a piece of sculpture, before
repeating it with the other leg.  Being totally naked, her body
stimulated more than my aesthetic interests.  Indeed, by the time that
she had returned her second leg to the floor, my penis had made an
appearance and was adamantly asserting its presence my slayed legs.

Always alert to manifestations of sexual excitement and never shy
about her part in causing them, Liu smiled at my erection and came
forward to straddle my recumbent body.

"I see that your libido has triumphed once again and that I can take
some of the credit for its victory.  I now want to see whether we can
use your excitement to make the remaining ten minutes of your training
routine a memorable experience for both of us.  I have occasionally
wondered whether it is possible to make love in a swing, and I am glad
for the opportunity to find out with you playing a dual role: both as
the swing and as my partner.  If nothing else, this experiment will
test both the flexibility of your groin and the ability of your sexual
apparatus to perform in the face of adversity."

Without further delay, Liu took aim and squatted down toward her
target.  Because my legs formed a V rather than a U, her hips
encountered my inner thighs so that she was suspended with her vulva
at least half a foot above the tip of my penis. Undeterred, she slowly
transferred more and more of her weight off her feet and onto her
perch.  As she did so, my thighs were forced further apart so that
what had been a V was becoming a U that could accommodate the further
descent of her buttock.  After a minute or so, the tip of my penis was
able to separate the lips of her vulva, but could go no further.
Sensing that my tendons would need time to stretch before deeper
penetration would be possible, Liu bided her time by flexing her
pelvis back and forth so that the tip of my penis would rub against
her clitoris. Needless to say, this form of mutual masterbation was
excruciatingly frustrating for both of us.  On the other hand, it was
having the desired effect.  Namely, my instinctive response was to
thrust my pelvis toward hers, and with each trust I got closer to my
goal.

When I was at last able to enter Liu fully, there were only a few
minutes left of the time Liu had prescribed for my stretching.
However, by then neither of us was watching the clock.
