I was at my desk on a Monday when Ann came in to remind me that she was to meet
her younger sister at the airport that afternoon.  I had not met Justine before
as she had spent the previous six years enrolled in medical school in Belgium. 
After earning her degree from the school at Louvain, she had enrolled for an
additional two years of training at U.C.L.A. in order to receive a degree from
that school as well and ease her way into practice in this country.  Ann had
described for me that Justine was about to start a three month rotation at NYU in
its obstetrics and gynecology service as part of her clinical training the
following week and Ann had asked if it was alright if she would be living with us
for that time.  I agreed and we anticipated that we would moderate our behavior
at home in deference to Justine's presence.

That evening we all had dinner together. Justine was enthusiastic about her
upcoming stint at NYU and she told us how medical education differs between the
U.S. and Europe, with the greater emphasis on clinical education here.  Over the
course of the meal, Justine mentioned that she was invited out to a friend's
house in the Hampton's the following weekend, and that she needed to do a little
shopping as she had only brought one bathing suit with her, and could use some
additional sport clothes.  Ann brightened and offered to take Justine out to our
shop, Vanities, and assured her that she would have a good supply of items to
choose from.

"That's good Ann.  It is tough to find something to fit me properly.  You
probably have the same problem even worse than I do."

"That's why I make sure that Vanities always has an adequate selection for people
like us."

Now Justine was not quite as busty as Ann, but she clearly was well- endowed,
although I could not tell quite the extent because of the blousy nature of the
dress she was wearing.

"If you are going out to Vanities tomorow" I said, "I'll drive you both out
there." Ann shot me a dark look, as she must have realized what I had in mind.

I pulled up in front of the apartment about noon the next day in order to drive
Ann and Justine out to Vanities.  Ann had not said anything to me about what I
would be doing during her and Justine's trip to Vanities.  The two of them hopped
in to my car and both seemed to be in an upbeat mood.  They had spent the morning
catching up and visiting with each other.  Ann asked me what was new in the
office and I told her there was a lot of work piling up on our desks, but at
least for the moment, no emergencies.

I dropped the two in front of the store and told them I would be back in about an
hour or so and that I would take everyone out to a late lunch.  Ann gave me a big
smile, which I took as a blessing from her for what I was about to do.  I pulled
in behind the store and using my key, entered the "viewing" room.

Business wasn't bad, I judged, by the amount of activity that was going on. 
Several people were trying on different items and one asian girl caught my eye. 
She had a terrific, lithe figure.  After about twenty minutes, Justine entered
one of the try-on rooms with an armful of bathing suits.  She hung them up one by
one on a rack opposite the mirror and seemed to take some time to decide what she
would put on first.  Almost absentmindedly, she unbuttoned her blouse and stepped
out of her slacks.  Reaching behind her, she unhooked her bra and turned to face
the mirror.  Justine had an impressive figure.  Her breasts were large and seemed
more assertive, less pendulous than Ann's and certainly not as big.  Like Ann,
she had a thin waist, but it was evident from the dark area at the front of her
panties that she did not share Ann's shaving habit.  I watched with interest as
Justine tried on all the different outfits that she had selected.  One that
particularly appealed to me was a shocking pink T-back number which did little to
cover her rear and which only had two wide vertical bands that were strategically
placed to cover her nipples, but which left the sides of each breast free to
catch the sun.

Shortly after I realized that Ann and Justine had finished their selections, I
ducked out the back and drove the car to the front of the store to pick them up. 
We had a nice lunch and then headed back to the city.  Ann did not ask me where I
had gone while the two were shopping and I did not raise the subject either.

The next day Ann and Justine were left to their own devices to spend their time. 
Over dinner, they filled me in on their day touring some of Manhattan's
interesting locales including the shops on Madison Avenue and lunch in Chinatown.
 Ann told Justine that she would be on her own the next day as she had to get
back to our office.

"I'd love to see where you work.  Why don't I come up, you can show me around and
I'll take you to lunch."

Justine's request unnerved Ann.  We both realized the next day was Thursday--a
day when we have our special dress code and when we don't ordinarily schedule
visitors.

"I have just so much to do, there's no way I could go to lunch.  Maybe Friday?" 
Ann ventured.

"I can't.  I have an orientation session at NYU on Friday."  Turning to me
Justine asked "It'll be o.k. if I see my big sister for a while tomorrow won't
it.?"

"Sure" I answered, not knowing myself how things would play out.

Later that evening, when we were alone Ann raised the subject of how we would be
the next day.  By then I had decided how I wanted things to go.  "No exceptions,
Ann.  I guess Justine will just see how we work on Thursday's."

I had expected more of a protest from Ann than she offered.  She did not seem as
upset as I thought she might and had she really seemed distressed, I was prepared
to alter our normal Thursday routine.  Something else, however, was going on.

On Thursday, business started off as usual with everyone doffing their tops and
some their bottoms as well, with Marie keeping her sweater at the ready for
unexpected visitors. From my open office door I could see that  Gerry was wearing
only thigh high stockings and black panties, and Ann had chosen today to wear
grey stockings and a matching garter belt.  I was surprised that she was not
wearing a skirt or any other sort of body covering.

Exactly at noon, Marie came into the back, a little flustered.  She had her
sweater on and in an urgent tone told Ann:  "Your sister Justine is out front."

"Bring her back here, please" was Ann's instruction to Marie.

Moments later I watched as Marie opened the door to our inner office space and
brought Justine in.  Justine saw Ann and Gerry immediately and looked at both
with a totally shocked expression.

"Ann!  What's going on?"  she finally mustered.  The sound of a strange and
excited voice prompted some of the others to come around to see what the
commotion was all about.  Maria and Sharon came within view and Justine quickly
realized that she was witnessing something she had never anticipated.

"Come on in to my office" I invited Justine.  "I guess Ann better explain to you
what this is all about."

Justine went in to my office quietly and took a seat on the couch.  Ann came
inside as well and closed the door behind her.  She sat opposite to Justine in an
armchair with her legs slightly spread--it seemed to me deliberately so--with her
nakedness completely apparent.  She made no move to cover up.

Ann explained that everyone who worked in my office was doing so voluntarily and
that all were very well paid, even exorbitantly well paid.  She said that I was
well-liked by the staff and that she thought that at least two others in addition
to herself were in love with me.

That was the first time that the word "love" was ever used in connection with our
relationship and I realized part of the reason why Ann did not prevent this
encounter with Justine.

Ann went on to explain how I was turned on by the visual and how everyone tried
to figure out ways to appeal to me in this manner. To illustrate this point, and
to make another, Ann described how she had designed and configured Vanities to
permit me to monitor the dressing rooms.  It took about ten seconds for Justine
to make the connection and realize that she had been there but two days previous.
She seemed to blush, but there was also what I thought was a faint grin curling
the ends of her mouth as she looked in my direction.

Ann continued with her account of how we all came to the work arrangements that
we had.  She then startled me a bit further by describing our Tuesday and
Thursday post- lunch activities, including what happens when the girls draw
different color marbles.

Justine interrupted to ask Ann if the reason she was shaved was another part of
my requirements.  "No, but I know Bob likes that" she answered.

There was silence for a moment and then Justine spoke. "Well I saw the buffet
lunch set up outside and Ann you told me what the routine is here on Thursdays,
and seeing how Bob already was watching me the other day, I guess there's no good
reason why I should inhibit you all from what you would normally do."  As she
spoke those words, Justine pulled the cotton top she was wearing over her head
and without hesitating for a second, removed her bra too.

I did not know what to expect so I announced that I was going to get some lunch.
Justine bounced up and said she was hungry too and followed me to where the
buffet was set up.  The rest of the office was already helping themselves and we
all took our plates and gathered around the conference table where we ate our
lunch.

When the time came to go draw the red or blue marbles, Gerry retrieved the jar
and started to pass around the table so that everyone could pick.  Lisa announced
that since she was not feeling that well, she was having her period, she'd staff
the reception area for the next hour or so.  Gerry gave Ann the chance to draw a
marble, she picked a red one, and then asked  Justine if she wanted to select a
marble.  I started to say that would not be necessary but Justine reached in and
held up a red one as well.  With the selection of the two red marbles, the draw
was ended and we all went in to the room where the cushions were arrayed on the
floor.

Gerry and Marie were particularly anxious to get things underway and no sooner
did they walk into the room than they arranged themselves side by side starting
to kiss each other and shortly each was fingering the other as well.  Sharon and
Maria took positions near each other and seemed to be principally engaged in
solitary activities although from time to time they leaned over to each other and
kissed.  Ann and Justine were a little awkward.  Ann started to kiss me and told
Justine to undress me as well as herself. Justine quickly took off her skirt and
panties and then unbuckled my slacks and drew them off me along with my shorts. 
Justine, probably for lack of what else to do, started to take me in her mouth,
but then turned her attention to nipping and biting my thighs.  I motioned for
Ann to pay some attention to my cock and she bent over and took me in her mouth. 
At one point she held me and offered Justine the opportunity to suck me as well. 
I interrupted that move and drew Justine to me. I wanted to feel her breasts and
kiss her.  Her mouth opened to receive my tongue and I lifted one of her breasts
to get a sense of its weight.  It seemed firmer, denser than her sisters', but
not as large.  After a bit, I encouraged Ann and Justine to trade assignments and
as Ann thrust her tongue in my mouth I reached down and felt how considerably wet
she was.

I then leaned back, in effect signalling Ann that I wanted her to tend to my cock
in whatever manner she selected.  I watched wide-eyed as she joined her sister
licking and sucking my cock.  As Ann swept her tongue up, down and around me, I
saw Justine mimic those movements and I noticed, more than once, that their
tongues would meet as they enveloped me.  At first I thought that was inadvertent
until I noticed that Justine's free hand had parted Ann's lips and that she was
working her fingers in and out of Ann.  Ann also seemed to be reciprocating that
attention by rolling one of Justine's nipples between her thumb and forefinger. 
The realization that Ann and Justine were relating to each other even as they
were tending to me was an overwhelming stimulation.  Almost immediately I reached
my climax and painted each of their faces and chests with my ejaculation.

As I leaned back against the pillows in relaxation, Ann and Justine both tended
to me and joined in cleaning me with the fresh washcloths that were set out for
that purpose. At one point Ann reached up to kiss me and while I was kissing Ann
on the mouth,  I reached for Justine and pulled her up towards me as well.  At
that point, I took Justine by the nape of her neck, and Ann by hers, and drew
their mouths towards mine.  After being in a position to taste both their tongues
at the same time, I withdrew from the fray, leaving both Justine and Ann twirling
their tongues around each others.  I then took Justine's hand and placed it on
Ann's breast.  Neither sister needed any more encouragement.

Using me no more than a prop to support Justine, Ann began to bathe Justine with
her tongue while Justine writhed with excitement. Initially Ann knelt between
Justine's legs and licked her slowly and gently, but Justine twisted so that she
had like access to Ann. Justine placed two fingers inside Ann and twisted them
about as she was nibbling and licking her.  Everyone else in the room was
completely captivated by the evident passion which these sisters were
demonstrating and as I looked around I saw every pair of eyes glued to Justine
and Ann while everyone, except for me, was almost absent-mindedly touching and
stroking themselves.

Ultimately and finally Ann and Justine became more and more energetic in their
activities and their grunts and whimpers which lead to very intense and
simulataneous orgasms for each of them.  As they finished they each lay against
me, nestled one in each arm.  I turned to kiss each and as I did I tasted on
each, the other.
