   "Wow, he's a big one."
   Krysta watched as her sister prepared to take the lion, the sigil in the
floor of the cage keeping her safe from harm.  She hugged her own swollen
belly, feeling one... two... ah, there was the third life inside her. 
Triplets this time, she thought absently as she saw the animal's penis
emerge from its furry sheath.
   Their mother Minerva watched as well through gold-green eyes, her breath
becoming slightly more coarse as she thought of how good it would feel to
mate again.  Charlotte was the youngest of the three women, and this was
only her second time, but she was doing it with such confidence that anyone
would think she had mated with the beasts for years.
   Charlotte felt the hot tip of the lion's rough rod at the edges of her
slit, then she closed her eyes and pushed backward.  The huge male grunted
in a half roar as he thrust forward, his hips shuddering forward as the
receptive female beneath him gasped with pleasure.  He grabbed her neck in
his teeth, the sigil doing it's work so that he could not injure her.
   "Oh god... ohhh... UH...!" Charlotte's head snapped back and she
screamed with passion, the huge beast above her shooting his load into the
grasping pussy that milked him dry.  With her generous, rounded ass still
high in the air, she shuddered as he pulled away, the sigil beneath her
preventing the barbs in his penis from shredding her soft vaginal flesh. 
She started to lower her hips but remembered her training and raised them
again to give a better chance of impregnation, which she had yet to
accomplish.  Minerva grasped the lion's collar and swiftly led him back to
his cage.
   Krysta realized she had been holding her breath and sighed deeply.  Her
slit was pulsating with desire, but she didn't dare mate again with her
litter so close to being born.  Closing her eyes she thought back several
months to the moment she had taken the tiger and sighed again as she
cradled her pregnant belly lovingly, the three cubs moving and kicking
within.
   Minerva came back then.  "That was amazing, Charlotte.  A great show,
and you remembered your training." Her eyes twinkled with pride.
   "Thank you, mother... is it safe now?  To lay down I mean?  Was that
enough time?"
   "Yes, sweeting.  Lay on your back now, and grab one of those pillows to
keep your hips up for a little while more."
   "Okay." Charlotte did as she was told and ran her hands through her
short black hair, then she closed her eyes and started dozing, the lion's
sperm doing its work deep within her belly.
   Looking at her naked daughter laying there becoming impregnated, she
sighed and decided to do it again herself in the morning.  It would feel so
good, both the mating and a huge, full belly.
   Strolling into the family's parlor, she looked at the pictures framed
there on the walls and atop the piano.  There she was with her own mother,
beaming with what must have been her first pregnancy.  It was so long ago,
but she still remembered the experience - you never forget your first time.
The rare bull was one of the last of its breed, and he seemed to know it as
he desperately pounded into her tight little pussy.  A perfect female calf
was the result nearly a year later, and her breasts ached with the phantom
memory of it suckling.  Her first child.
   Minerva spotted another photo of herself with her mother, and this time
she was barely showing, but had already formed an extra set of breasts
under her regular human ones in preparation for the litter.  Her mother was
old and grey in this picture, too old to mate any longer, but her hand on
Minerva's belly and broad smile showed how happy she was.  The mountain
lion lounging behind them seemed to smile as well at how well his daughter
had performed.
   In another picture she was holding little Krysta's hand and was pregnant
with Charlotte.  Krysta had her other hand on the back of a polar bear
while Minerva's free hand held that of a mountain gorilla.  A true family
portrait, with the fathers of both girls included, she thought with a
smile. She missed her own father, but at least she had a few photos, a mane
of amber hair, and his gold-green eye color to remind her.
   She was the matriarch of the family now, she reflected.  And she was
doing a damn fine job... the zoos, farms, and wild breeding programs were
always thrilled with the strong, healthy animals she provided to them.  It
was almost a shame that she could never explain how her breeding program
worked.  And in all these years nobody had figured out that they only used
male animals.  Minerva chuckled to herself.  Yes, definitely in the
morning. The big one in meadow five.  She rubbed her own belly in
anticipation, a moist spot forming in her panties.
   Krysta came in then, smiling and cradling her belly out of habit.  She
loved what her family was able to do and woke up each day full of
anticipation and energy.  Between getting to know each male on a personal
level, feeling the creatures within her grow, being able to watch her
sister fuck animals and swimming in the big glass pool... life was good. 
Her long, strong fingernails made good scratchers for her itchy belly, and
her snow white hair was fun to tint all sorts of colors.  She was truly the
eternal optimist and lived life to the fullest, already having produced
eight sets of babies.  But no human ones yet... you never knew when they
were going to come out human.  Or passably human-looking anyway.
   The next morning Krysta went into the breeding room and discovered that
the cage had been set up freshly, the sigil washed and oiled, clean linens
off to one side, a stack of pillows within reach.  But she was already
pregnant... and Charlotte had just mated... they wouldn't know if it had
taken for a few weeks, so who...
   Then it dawned on her what must be about to happen.  She grinned and sat
down in one of the comfortable rockers to watch the show.  This would be
interesting.  Charlotte called out from the kitchen and Krysta called back
to let her know where everyone was.  Or would be soon.  A smile broke
across her face as Charlotte walked in with a cup of coffee, still in her
pajamas and slippers.  A look of confusion briefly came and went, and
Charlotte began to smile as well as she realized the situation.  Then
Minerva entered with her chosen mate and their jaws dropped.
   "I didn't realize I'd have an audience," their mother chuckled.  Then
she prodded the elephant into the breeding cage gently.  The girls looked
at each other and Minerva, seeing their disbelief, simply pointed at the
sigil.  Neither of them could fathom how this was going to work, but
obviously the beast had been on their property for a reason.
   She let her robe slip down and exposed her body, slightly heavier than
in youth but still voluptuous, her slightly enlarged belly the result of
many, many long gestation periods with large and heavy loads, three pairs
of extra breasts running down her stomach along the milk lines like
soldiers at attention.  She had been doing this her entire life, since she
had come into season the first time over 30 years ago.  Not once did she
regret who and what she was... never for a moment.  Gooseflesh made the
light golden hairs on her arms stand erect.  Then, in the center of the
sigil, she laid down a thick mat and bent over it, her waiting ass high in
the air.
   The huge bull sniffed at her with its trunk, then it gently fondled her
slit.  Minerva gasped with the feeling of it, her daughters transfixed by
the scene before them.  The elephant opened and closed his mouth as he
worked on the woman's cunt, rocking his huge body back and forth slightly
as her pussy moistened, becoming ready for him.  It always smelled and
looked perfect to whatever animal was with her, another benefit of the
ancient sign below her.  A sign handed down through the line of women since
before records were kept.  They could mate with any mammal even without the
sigil, but its magic made the act safer and easier to perform... and of
course, much more pleasurable as a result.
   Minerva licked her lips and closed her eyes, uttering a low moan that
the bull understood to be "please." He carefully moved forward and over the
waiting woman, his massive cock unsheathing itself.  Krysta and Charlotte
involuntarily leaned forward in their seats.  The beast pushed against the
reddened slit and, to their amazement, began to slip inside.  Minerva
gasped with pleasure as she felt the huge shaft enter her, forcing her wide
open.  Over the years many creatures had penetrated and stretched her cunt
so that she could take almost anything inside, and the sigil's magic
ensured that she could not be injured, so it created a perfect union.
   The bull didn't seem to care or notice that his rod had become somewhat
smaller, but Minerva could feel that her cunt was being stretched wider
than she had ever known and moaned loudly.  Her already oversized pussy was
responding to the sigil's magic and growing bigger still to accommodate the
huge rod pushing its way inside her, but there was still enough resistance
that the stretching sensations drove her wild.  She grunted and began to
rhythmically hump his cock, feeling it open her up to new dimensions,
feeling her flesh pushed to the limit.
   He closed his eyes and let her do as she pleased for a while, then he
began to grunt and match her rhythm very gently so as not to send her
sprawling.  Panting and screaming, Minerva slammed back into his rod harder
and harder, faster and faster, until they both orgasmed at the same moment.
   A flood of elephant jism filled her pussy and stretched it even further,
driving her wild.  Her cunt spasmed and worked hard against the cock inside
her, the strong muscles of her cervix contracting quickly to suck his sperm
deep inside her fertile womb.
   The girls, still watching with mouths agape, could see the huge bulge in
her gut where his cock rested, and had watched in amazement at the moment
he shot his load - her belly had rippled and bulged wildly as it fought to
contain everything inside it.  Every time the bull moved, they could
clearly see the bulge in their mother's belly shift position, her eight big
breasts rocking back and forth, her eight marble-sized nipples erect and
hard.  Their pussy lips pulsated against their chairs as they finally
watched him pull his tremendous shaft from her, the bulge receding as he
did, her cunt returning to its regular size... mostly.
   Minerva grabbed a stack of pillows and propped her thoroughly reamed
pussy up nice and high before too much of the precious sperm spilled out.
The girls sighed with wonder, until finally Krysta realized that someone
had to put the bull elephant back, so she got up and guided the great beast
back through the gate to an adjacent holding pen.
   When she returned, she saw that Charlotte was still staring in wonder at
her mother, absently fingering her own slit.  Krysta's cubs kicked hard,
and she smiled again.  She was in an especially good mood because that
morning she had noticed a new pair of nipples forming below the original
two and wondered how many she would eventually have.  Once they formed
along the milk veins, her mother had explained, they never went away. 
Krysta played with the sensitive pink spots through her shirt, then the
girls retired to their rooms for a little fun as Minerva dozed atop the
pillows.
   Minerva knew she had taken a risk with the elephant, but she could
always fall back on the sigil if need be, drawing one under her bed for the
final few months of pregnancy and the birth.  But it turned out not to be
necessary.
   A few months later, Krysta's daughters were born without incident, the
three squirming cubs suckling at their mother's four milky breasts. 
Charlotte was beginning to show the day they were born, the lion gifting
her with five cubs for her first pregnancy.  Krysta had to admit that she
was a bit jealous - her sister would get one more pair of tits than she had
so far.  But there was still lots of time to attain more.
   At Charlotte's birth Minerva was growing larger.  She rubbed her belly
as she watched the five beautiful little cats suckling at her daughter's
many breasts, anxious for her own baby to make her grow larger and fill her
with milk too.  Later in the day she claimed she was taking a nap, but
Minerva fondled herself instead, running her fingers over her lines of hard
nipples like those on a bitch dog's belly but deliciously bigger, cupping
her eight fat breasts in turn, and looking down at her growing womb as she
massaged her clitoris into a satisfying orgasm.
   After seven months she could tell by its shape and size that the life
inside her was another human-like daughter, and although she was a little
relieved, she still wanted to try again just to see what carrying an
elephant inside her body would be like.  Minerva often played with her
multitude of breasts, and as her state advanced she would suckle on
herself, drinking her own milk as she masturbated into delicious orgasms.
She had almost forgotten how incredibly erotic it was to be hugely
pregnant.
   When the pains began, she moved into the birthing bed as they all did,
the hereditary sigil carved into the floor below.  Birth was swift and
uneventful, mostly because of the enlarged size of her vagina.  The
beautiful and intelligent deep brown eyes of her new baby daughter reminded
her so much of the bull elephant, her thick black lashes predicting that
she would be a real beauty.  Minerva's daughters crowded around their new
sister Phaedra and tickled her stubby, wrinkled little toes.
   "Okay, smile everyone... well, except him of course." Charlotte ran back
into frame, the timer on the camera set at five seconds.  She patted the
elephant behind the four of them, and it seemed to her that he had a
twinkle in his big brown eye as the shutter clicked.
