 The alien was a member of a highly evolved race but dwindling race who
unbeknownst to the world's public had just conquered the earth.  They
privately demonstrated to the world's major powers just how futile an armed
conflict against them would be.  They were actually a peace loving race and
believed it was their mission to stop warlike tendencies among the planets
in the galaxy.

   However they would allow us to continue governing ourselves provided we
provided them with willing human females with which to develop methods to
breed alien/human hybrids.  Over the last few hundred years, their females
had been slowly growing sterile.  All their scientific knowledge couldn't
stop this and finally all their females became sterile and no longer
capable of producing offspring.  Trying to reproduce strictly through
genetic engineering wasn't a solution and their very DNA started showing
signs of inevitable decay.  So these hybrids would eventually produce a new
race and provide a way for their civilization to go on, although in a
different form.

   When doing tests on abducted humans, they found that even genetically
mutated male human sperm could not fertilize their females.  However male
alien sperm when genetically altered was capable of impregnating a human
female.  However no physical sexual contact was necessary to produce
offspring.  It could all be done in a science lab.

   However when one of the alien males decided to try physically mating
with a human female, he quickly discovered that mating with women was much
more pleasurable than with their own kind.  Other alien males found out,
and they insisted in actually mating with human females.

   So the female staff at the various facilities now had to deal with horny
alien males literally jumping the female staff.  Secretive hushed whispers
soon started circulating among earth women in these facilities around the
world that this was not necessarily a bad thing.  As these reports got out
in the public they were quickly discredited and soon forgotten, but then
often re-emerged again like a Phoenix.

   It was not known until later why the women only initially complained,
but not strenuously, and each dropped their complaints after the first
voicing and wished it dropped.  After the reason was discovered, then
respiratory and skin contact precautions were initiated but these
precautions slowly became forgotten as time passed....

   The male Saurians were a physically large, powerful being with a male
average height of seven feet, two inches while their females were average
human female height.

   Karen, the head researcher of this facility was in late with only a
female doctoral assistant working with her in the lab.  The woman, fresh
out of graduate school had already been shown taped video footage of many
women having sex with the very alien currently in their lab.  Of the
peculiar things that were discovered with the aliens was that they were
multi-orgasmic, other things of a sexual nature were discovered that helped
keep the whispered rumors alive and very well.  The Alien being had been
following this research technician all day around the enclosure.

   So as Karen sat quietly reading a report in the control room, she was
surprised to see that the woman was quietly entering the alien's enclosure.
Through a concealed color high resolution video camera, equipped with
highly sensitive directional microphones, Karen saw the woman checking to
see if she was alone.  The woman then walked straight into his enclosure.
Though obviously pleased, the alien kept his cool about her being there and
approached her calmly.

   To Karen's surprise, the woman then started to strip.  Once naked, she
was quickly on her hands and knees waiting for him.  The much larger
Saurian then mounted her with great gentleness.  His midsection was now
nested against her back.  His genital area was slightly behind and above
her firm round buttocks.  His member was completely enclosed within a slit
on his lower abdomen, concealing the actual true size of his member until
aroused, and had now just started to peep out.

   As it emerged the member crept out over her buttocks emerging toward and
then over her tailbone, starting to show the evidence of it's true enormous
size.  She then bent her back downward slightly, which raised her butt
cheeks upward inviting the emerging male's organ into her.

   She gently starting lowering and then raising her buttocks, caressing
his member, then she started to bend her back a little bit lower with each
up and down motion until her vagina was rubbing the partial length of his
shaft.  Her labia had already engorged and swollen, her swollen, distended
labia lips visibly pulsating, had spread apart like the petals of a flower
allowing his thickly ribbed member to slide over her opened cleft, over her
clitoris and then back down bumping her clitoris and inflaming her desires.

   His very large sex organ continue to emerge out from the slit on his
lower abdomen, and then the tip of his member probed at the open gap just
at the base of where her buttocks separated and her vaginal opening lay.

   The insertion was very gentle and slow as the 14 inch long; 21/2 inch
thick ribbed organ that was visibly swelling to an even greater girth began
to slide deeper into the woman with each gentle repeated thrust that eased
a little more in with each thrust.  A low guttural moan escaped her lips as
it was slowly buried deep inside of her.  The smoothness with which the two
only distantly related species had coupled was amazing.  As the girl
started rocking back and forth onto the cock, it swelled till its girth was
4 inches across!

   Slowly at first and then with increasing intensity, a behavior their
species shared then set in.  That being the rhythmic thrusting of
copulation.  Her outer and inner labia clung to the massive organ as it was
pumped in and out of her.  The fucking was very human in duration and
surprisingly tender.

   The slit on the Suarian also acted as a large suction cup, repeatedly
sucking and then releasing her vaginal lips, labia and clitoris, swelling
and engorging them, pulling them outwards as he withdrew his member, the
suction breaking audibly as his length emerged and then reattaching again
as he thrust his member back in.

   It was obvious to Karen that the woman was more than enjoying the sex.
Karen was no prude, she and her boyfriend watched porn flicks regularly and
no porn acting compared with the feelings this woman was exhibiting.  She
was rhythmically raising her butt in response to his shaft being plunged
into her from behind.  Her breath occasionally got caught in her throat as
the male organ was driven deep into her eager and willing body.  He was
breathing hard too, his lust being expended on his very willing and
enthusiastic partner.

   The alien as always was fully enjoying fucking with a human female and
all the human females enjoyed and desired it tremendously as the Saurian's
secreted a sexual pheromone from their skin pores as well as from their
member that incited desire in females.

   This was the secret that became known with a whisper that reached around
the world.

   Also the Saurian body temperature was 26 degrees warmer than humans,
which further increased the passion as the hot member slowly pistoned into
her contracting pussy, almost withdrawing then plunging deep into her
rhythmical contracting depths.

   Finally, the girl climaxed thunderously.  Her head dropped, and she let
out a long, slow extended breath.  As if blowing on a hot bowl of soup. 
However the Alien wasn't finished with her.  He lifted her up onto a table.
She then laid back and spread her legs apart.  Her pubic hair was neatly
trimmed with just a small triangular patch showing above her vagina
exposing her moist vaginal opening.  Her lean muscular body heaved with
breathes of excitement as she waited for him to enter her again.

   She literally jumped as the tip of the hot moist organ made contact with
her wet openly pulsating pussy.  The alien then gently grasped her calves
and spread her legs apart and pressing her knees up towards her well
endowed chest.  Then he slowly entered her willing body.

   The Alien could feel her vagina open and stretch as he slowly introduced
his member into her.  The member was very hot, but he was having trouble
getting the entire 14 inches of his swollen thick member into her. 
However, shortly after it squirmed around a bit, this stimulation along
with the thickly secreted sex pheromones from his member, increased her
production of vaginal fluids, and it quickly slipped completely inside her.


   The alien then finally began to aggressively fuck her.  Occasionally his
member would slip out and bang against her tightly puckered anus and then
he or she would reinsert it into her pussy.  Her vagina was comfortably
tight so that her vaginal walls pressed tightly on the shaft and caressed
it with strong rippling muscle contractions into her depths.

   The sex pheromones that were being secreted in thick copious amounts
were running down over her anus, stimulating it and causing involuntary
muscular rhythmic contractions of the anal muscles and sphincter.

   Her swollen pulsating labia lips clung to the pistoning organ as the
ring of muscles around the vaginal orifice gave extra firm squeezes.  Karen
was mesmerized by the sight of these two beings locked in mutual pleasure,
her own desire strongly building.  Suddenly the intern's hips began to
thrust more aggressively as she slowly rose to another massive orgasm.

   As she peaked repeatedly under the tenacious, but slow and tender,
thrusting, she began making small grunts as each breath was expelled. 
Finally, as his own pleasure became too much, the alien slowly decreased it
thrusts and ejaculated deep inside her as he leaned over and held her
close.

   The secretions from his member had actually caused her cervix to dilate
allowing his massively thick member to penetrate deeply into her womb. 
From the high gain directional microphones mounted to the cameras, Karen
could hear her lab assistant moan

   "His cum is so HOT!  I can feel it squirting, it feels so powerful! 
Yes. Ohhhhh. . .  he's cumming, I can feel him squirting like a firehose,
he is shooting into my womb, So hot, so very hot . . .  so good." GAWD he
is so deep!

   She elicited a moan as she felt each ejaculation which continued for
several minutes....  pumping copious amounts of cum deep within her.  The
tip of his member repeatedly flexed upwards two inches from the force of
each of his powerful explosive ejaculations erupting from the tip.  She
deeply moaned each time she felt the tip moving deep within her and then
again from the hot cum blasting onto, then rebounding off the walls of her
womb.

   Two unique evolution adaptations had evolved in the Saurian species to
ensure impregnation: 1.a very long, massively thick cock that could
actually enter the womb and, 2.a very large momentary bulge would form near
the base of his cock with each powerful pulse of his ejaculation that
ensured that no semen would backflow out of the vaginal canal until the
womb was full of fluid and his member withdrawn.

   The repetitive inflation of this very large bulge repeatedly putting
pressure against her G spot caused her to experience several tremendous
orgasms coupled with the copious amounts of hot fluid blasting against the
walls of her womb.

   These power ejaculations last for five full minutes, filling her womb
completely and visibly distending her abdomen from the volume, then he
slowly pulled the organ from deep inside of her, leaving her vagina gaping
open from the size of his member but also from the pressure of the volume
of cum now gushing explosively out of her pussy in a torrential waterfall.

   Saurian's ejaculated cum in a quantity more than any known earth or
alien species; it had been measured at a gallon, with larger Saurians
producing slightly more!  They also had the unbelievable capability to
rapidly reproduce the same enormous quantity of cum as benefited a
multi-orgasmic species.

   Her belly was visibly distended from the volume and was slowly returning
to its original flat muscular shape.  As the cum continued to pour out in a
torrent, she was moaning gently from the feeling of the hot liquid
emerging. Her swollen distended labia lips were opened like petals of a
flower and pulsating slowly.  Each contraction squirted cum out in an
arching stream.

   She lay back exhausted with her legs still spread breathing heavily on
the table.  The Alien, now gently turned her over and she got back on her
hands and knees, evidently finding inner strength for another bout of
inflamed passion helped along by the secreted pheromones that acted as a
physical stimulant as well as a powerful aphrodisiac...

   She gently starting lowering and then raising her buttocks, caressing
his member between her ass cheeks, then against her tightly clenched anus.

   Saurians had another unique ability to shrink and then expand the last
several inches of the tip of their members to facilitate entry to any
passage.  By now, he had reduced the tip to about an inch to ease passage
into her tight muscular ass.  When contracted to this state, the member had
a life of its own, squirming around, self-guided by the tip that was
imbedded with heat sensitive receptors guiding the squirming member to the
hottest heat sources.

   He raised and lowered his hips against the entrance she had caressed
against him earlier, her thighs flexed her butt back as she felt the
squirming tip probe her entrance, she gently pushed back and the narrowed
tip began to enter...

   It gave her a swirling zeal of pleasure, surging up from her clenched
opening into her abdomen.  She moved tightly against him as she wedged onto
his swelling thickness and felt her anus start to open to accept his
member, his member again growing thicker as the deeper it got.  Her anus
was rhythmically contracting powerfully from the pheromone secretions, the
repeated contractions slowly drawing him in, inch by inch, just by
involuntary muscular contraction alone as it stretched against his now
thickly swelling shaft, then her muscles and inflamed passion just went
wild, and she started slowly thrusting back, driving herself further and
further down onto his very long and very thick member.

   Soon, she realized she had taken in all 14 inches of his length
comfortably.  His girth had again swollen to its former 4 inches across.  A
shaky breath escaped her lips, and soon she felt him start to withdraw,
slowly and deliberately.

   Slowly his tempo built and a tingly feeling began in her clitoris and
deep in her bottom, then spreading warmth throughout her body signaling yet
another orgasm.  Her breathing became quicker, each breath raspier more
labored and louder, much louder as her arousal grew.

   The incredible feeling in her clitoris, inside her vagina and deep
within her ass was excruciating.  She wanted to orgasm.  Her pussy
contracted involuntarily, clutching, grasping in time with her anal
contractions.

   She gasped again and then rhythmically breathed as his body took up a
tempo of lovemaking.  He filled her in a delicious deep way; size creating
a friction to the walls of her ass, while her outer gripped his pistoning
cock in a rippling tight intimate embrace.

   Incredibly, she felt his cock growing even larger inside her, increasing
the friction.  Her delirium mounted as another countless orgasm exploded in
her brain and aftershocks reverberated through her nervous system.

   She was close to feinting from the onslaught her body was enduring and
craving at the same time.  Despite the width and length, she started to
feel her addictive senses reawaken within her, causing her body to heat up
further, her walls to become tighter and cause more secretions.  In doing
so, he began to move like a jackhammer, grunting slightly with each
quickening thrust.  She bit her bottom lip to stifle a loud shout, and
relaxed beneath the creature, allowing him to exploit every inch of her, as
she rubbed her clit bringing herself to the brink of orgasm.

   He suddenly thrust hard into her, pushing himself as close as he could
to her.  His hips shook, his head tilted up to the ceiling as he let out a
low moan.  She knew with anticipation what was to come, and soon she felt
the thick long shaft in her clinging tightness start to powerfully pulse as
he started firing his load, in hot shuddering blasts from his powerfully
lurching member.

   She felt the hot bubbling gushes deep inside her.  She shuddered and
started to scream, louder and louder with each mind numbing contraction and
each powerful eruption of his cock deep within her, filling her as before
with an enormous amount of hot cum, throwing her over the edge into her own
shattering orgasm.  As wave after wave of pure exhilaration washed over and
through her she slipped into a world not experienced before.  All senses
slowed down to a state of slow motion.

   For a full 5 minutes he continued to pump her full, she felt each
powerful hot ejaculation deep within her, the hot volume building into an
incredible pleasurable pressure and deep spreading warmth.  Finally, he was
able to pull himself out of her tightly clenched ass, which was still
involuntarily contracting, rhythmically from the pheromone secretions.

   She gently moaned with pleasure, as he slowly withdrew.  A very loud
prolonged slurping sound was picked up by the highly sensitive directional
microphones, as inch by inch slowly withdrew from deep within her and a
final loud suctioned slurping POP!  was clearly picked up by the
microphones when the tip emerged.

   As before, her abdomen was visibly distended from the volume.  Her tight
anus was still repeatedly contracting slowly.  Each contraction/relaxation
cycle explosively jetted a powerful stream of hot cum out into the room;
each stream elicited a gentle moan from her feeling the hot voluminous
liquid repeatedly erupting like a hot geyser...  her contracting belly
visibly going down with each powerful squirt.  It took a few minutes for
the geysers to finally die down....

   Karen immediately wondered how to broach the subject of what just
happened with the intern in the morning.  Karen herself was incredibly
turned on and had been thrusting 4 fingers into her sopping wet pussy as
she watched the intern, wishing for one of her dildos she had at home. 
Although it was an unexpected turn of events, Karen wondered if the intern
would entertain the idea of both of them doing the Saurian at the same
time, or a pair of Saurians!  She already knew the intern would eagerly
accept.

   Somehow and from whispered rumors abounding about Saurian sex and the
shared looks among the women researchers in the many facilities around the
world, the ones she had the previously ignored as fanciful & fantasy, she
now knew were proven true beyond belief
