 A naked Serena, now recovered from her adventure with the monster of the
lake, looked at the two paths through the cave and wondered which one to
take.  She did an "eeney-meeney-miney-moe" and ended up with the left
opening.  She very carefully entered.

   The passageway was narrow and the floor was covered with the same black
sand as the beach.  The air was a bit chill.  There was a breeze blowing
into Serena's face, so she figured she was heading toward an opening.  She
shivered a bit and pushed on.  She walked for roughly an hour, and came
into a wide and high cavern.  She stopped for a minute, took some water
from her water skin, and took a few steps into the cavern.

   This cavern was well lit by what appeared to be large crystals scattered
around its sides and on its roof.  A small stream ran briskly through the
center.  Scattered about were big and comfortable cushions, as well as
blankets and coverings.  There were two stone huts over by the exit on the
other side.  Serena took a few more steps and headed to the cushions.

   She sat down on one of coverings.  It was really a large and warm
comforter.  Beside the comforter was a bowl with fresh fruit.  Serena
figured that it must be lunchtime, so she grabbed a piece of fruit and
proceeded to munch on it.  She was startled when she heard a deep basso
voice address her.

   "Ho!  Who eats our food?"

   Serena stood up and took a look at what was addressing her.  She gulped,
and wished she hadn't taken the piece of fruit.  The creature was huge.

   The creature stood about eight feet tall, and was proportionately broad.
Its entire body appeared to be very muscular.  The arms, however, were
overly long, extending to the knees.  They ended in a pair of oversized
hands.  Its skin was a pale green color, and appeared to have a rough
texture.  It was stretched tight over its muscles.  It was wearing some
sort of kilt made of animal fur that came to just above the knees.

   The face was another matter.  The forehead was high and sloping, like
that of an ape.  The brow ridges were thick and pronounced.  The nose was
almost non-existent.  The mouth was wide and lacked lips.  It appeared to
be stuck in a perpetual wicked grin.  And the teeth were really fangs. 
Serena gulped a second time.

   "Ho!  Girl, why do you take our food?"

   Serena blinked and said nothing.

   "Who takes our food?" asked another creature, entering the cavern from
the tunnel Serena was going to use to leave.  He was almost a twin to the
first monster, but his kilt was a different color.  "Who steals from us?"

   "I do," said Serena, meekly, and moving off of the comforter towards the
stream.  "But I was hungry, and needed some rest.  I am sorry.  If you help
me leave the cave and cavern, I will make restitution."

   "Ho!" said the first creature.  "You will make restitution.  My brother
and I will eat you!  Ho!"

   Serena slowly backed away as both creatures moved toward her.  They were
too large, and she was frightened.  So this was how it was to end.  She
expected better from her Master, but he had betrayed her.  She slowly
stepped back towards the comforter, hopefully looking for an escape.

   The creatures move quickly.  The first creature got to Serena first.  He
quickly grabbed the girl, threw her on the comforter, roughly spread her
legs, and began to lick and nibble her mound.  His tongue was a bit rough,
and this caught Serena completely off-guard.  She had expected to be
devoured, as in a meal.  Instead the creature was doing her orally!

   "Hmmmm," said the creature.  "She taste good!"

   Serena wiggled under the workings of its tongue.  The tongue was long
enough and wide enough to cover her from her anus to the middle of her
mound.  The licking was exquisite.  She forgot her fear and laid back to
enjoy the pleasure.  He was getting her close.

   The brothers switched.  The second brother's tongue was a bit coarser,
but still very, very pleasurable.  The second brother got her right to the
edge.  Serena was ready to explode.  She was panting and gasping.  When he
slowed up, not allowing her to climax, she opened her eyes and looked up.

   "Oh.....my......God!" she screamed.

   The first brother had removed his kilt, and what Serena saw terrified
her.  His erect member was easily half the length of his thighs.  It was
thick, about half as thick as a can of soda.  The tip was like a normal
male penis, but the thick and heavy shaft frightened her.  It was ridged
along its full length.  And the testicles were huge and heavy.  Serena
could only gasp out a "No!"

   The second brother, who had aggressively tasting her womanhood, moved to
his knees and parted her legs.  The first brother pinned her shoulders. 
The second brother gently rubbed his huge penis over her mound and slowly
inserted it.  Serena climaxed instantly.  He slowly pushed until he felt
the tip of his penis touch Serena's cervix, and then he stopped.  He held
it there for a bit, and then slowly began to rock back and forth.

   Serena had thought she had died and gone to heaven.  Her Master was
large, but not this large.  She had never had anything this huge inside of
her.  And it felt heavenly.  She took a deep breath and relaxed.  Then she
began to wiggle about his penis.

   The first brother relaxed his grip on her shoulders and sat back on his
haunches, watching.  He stroked his member to keep it hard.  He would go
next.  The other brother fucking Serena was driving her to a second climax.
He would however, climax before she did.  It had been a long time since the
two brothers shared a woman.  After all, they shared everything else in
their lives.  Why not a human female?

   Serena was panting and squealing with sheer pleasure.  This huge cock
inside of her was heavenly.  She wanted it to go on forever.  When the
second brother climaxed, it felt like a gallon of hot liquid was filling
her up.  It ran out of her vagina and down her thighs.  When he finally
spent himself, he withdrew.  Then the first brother took his place.

   Serena looked up at the first brother and smiled as her took a position
between her legs.  She reached down, gently stroked him, and guided him
inside of her.  She took as much of him as she could, and then she embraced
him with her arms and legs.  As he began to slowly pump inside of her,
Serena climaxed.

   The first brother would take just a bit longer than the second and would
also empty his seed into the girl.  When he finished, he withdrew and
stepped aside.  Serena asked them their names, and they said they were
called Max and Jax and shared everything.  They were twins.  Serena
informed Max and Jax that they could share her anytime they wanted.

   Serena would spend the next two days (she had no sense of time in the
cavern) with Max and Jax.  She would take them in her vagina, her mouth,
and her anus, including a double penetration.  She had had her anus
penetrated by toys and penises before, but never anything this huge.  And
she adored the double penetration.

   The day she left, Max and Jax fashioned a small, green g-string for her
to wear and soft pair of sandals for her feet.  Serena headed down the
tunnel with her water skin refilled and a small supply of food.  Max had
told her that the path through the mountain would bring her out at the top
of the cliff.  Serena headed into the tunnel to see what further adventure
she could find.  She didn't know what she liked best.  Was it the weird
tentacle monster or the two brothers?  She would have to make a return trip
and find out.
