 The Sacrifice Part 4 by Baphomet <mail.baphomet@gmail.com>

   "I was thinking of naming him after you -- 'Phillip, Jr.'"

   "Two Phillips in the same house?  That might get confusing.  How about
'Joachim', after your father?"

   "He would have liked that.  And if it's a girl?"

   "Perdita..."

   "Perdita?  I've never heard that name before."

   "It was my sister's."

   "I never knew you had a sister.  Phillip, where is she?"

   "She died when I was born.  She was supposed to have been my twin,
but... the doctors could only save one of us, so they chose me."

   "Oh, Phillip..."

   Her hands ran across the hairs of Phillips chest.  She caressed him
gently.  She let her fingers slide down to his stomach, then to his thighs.
Finally, she found his cock growing hard between his legs.  She stroked it
eagerly, bringing his manhood to life.  She was several months pregnant,
but still she wanted him.  She buried her face in his chest hair and
inhaled the sweet aroma of his ...  sweet aroma...

   The sickening combination of sweat and body odor woke Sister Anne out of
her dream.  It wasn't Phil's musky aroma that welcomed her, rather it was
the filthy, sickening stench of her captor, Earl, that shocked her to
reality.

   She pulled herself away from his sleeping form.  His snores echoed in
the darkness.  She plodded to the broken sewer pipe that jutted from the
corner that served as her toilet and relieved herself.  She felt the
queasiness again and knelt down to vomit.  Her hand palmed her stomach. 
How long had she been here?  Time was meaningless in this dungeon.  She
couldn't remember the last time she saw the sun.  Days?  Weeks?  Months?

   It was long enough for familiar changes to take effect and make her
absolutely certain.  She looked over at Earl.  She could make out the
outline of his obese form in the dark.  His cock hung limp from the mound
of wiry public hair between his legs.  He would be the father of her child.


   When Sister Anne woke again, Earl was gone.  It didn't matter.  He would
always come back to her to fuck her or feed her.  Sometimes, she would hear
the screams of other girls in the night as Earl took them for his pleasure.
In addition to Mia, there were a couple of blondes he brought in.  They
were so young, Sister Anne was afraid to guess their age.  When he broke
them, he took them both together.  Sister Anne guessed that they were
sisters.

   Despite his forays, Earl always came back to her.  Sometimes, he was
fresh from a fuck and she could taste the salty residue of another woman's
vagina on his cock.  She never said a word.  She only took him inside her
mouth, her pussy, her ass.  He never failed her.  He was always hard and
ready.  He always had cum to give her.  Sometimes, he surprised himself
with the number of times he orgasmed and by the sheer volume and thickness
of the cum he produced.  She was the only one, he told her.  She was the
only one who could draw it out of him without fail, time and time again. 
She was his favorite.

   The blondes came and went.  Where they came from and where they
disappeared to was beyond her concern.  There were probably other girls as
well.  She could never be sure who was who in the chorus of screams and
shouts during the night.  Yet, Mia remained through it all, and this
bothered her.  Why did he need that slut, or any of them, when he had her?
Didn't he know she was carrying his child?  Yet, he didn't seem to care. 
More than anything, she wanted Mia to go.  She wanted her to disappear like
the other girls.

   Earl soon began to give Sister Anne more freedom.  For the first time,
she was allowed into the upstairs of the building.  It was a filthy hovel
with food, filthy rags, and unwashed dishes everywhere.  Rats and flies fed
openly on his scraps.  She cleaned as much as she could, but her main duty
was to tend to the vats of stew for Earls'....  "collection" downstairs.

   Soon, she was the one who slid open the little doors to demand an empty
bowl.  She scooped out mouth-watering stew or plain oatmeal or sometimes
just water, depending on Earl's directions.  She changed the sheets, washed
the linens, and, on rare occasions, Earl had her burn some young girl's
clothes.  Sister Anne asked no questions.

   She turned a blind eye to everything because nearly every night, Earl
would come to her.  He would spread her legs and lower his body atop of her
and give her the one thing that made her feel alive.  She would feel him
penetrate her and force her to give up her secret pleasures to him.  Then
he would share himself with her.  Again and again, he would leave his seed
inside her.  A part of him, in her.

   As she pushed the cart, she would feel him between her legs.  Sometimes,
he would dribble out and stream down her leg.  It was his gift.  His cum.
She lived for it.

   Day after day, Sister Anne pushed the cart down the dank, lonely
corridor.  The fluorescent light bulbs buzzed and flickered as she went
from door to door, dispensing food to gaunt eager hands.  Her belly had not
yet begun to swell, but she could feel the fruit of Earl's seed inside her.

   She smiled at the thought, when suddenly, muffled voices caught her
attention.  She couldn't hear what they were saying, but she could hear two
voices a man and a woman....  or maybe a young girl....

   She wheeled the creaky cart down the hall and to the door that was the
unmistakeable source of the voices.  The man was talking.  Then a giggle.
Then a woman...  no!  It was a girl...  then a man again.  She opened the
little window.

   The room was beautiful compared to the stark cells in the rest of the
basement.  There were no cracked and peeling walls with water dripping down
the sides.  Instead, the room was neatly wallpapered with a brilliant
pattern of brightly colored balloons.  The floor was carpeted with a shaggy
pink remnant.  The bed was beautifully canopied with pink sheets and there
were toys strewn about everywhere.  Earl lay laughing and smiling in his
soiled and stained tank-top.  The whiteness was all but gone and it looked
grey with disgusting yellow stains around the armpits and chest.  Next to
him, was a girl in a white top, a pleated pink skirt and a pink beret. 
Luxurious blonde hair cascaded down her shoulders.  She and Earl were
playing with dolls, their tiny clothes long stripped off.

   Sister Anne eyed the girl carefully.  A jealous rage built inside her,
but it was quickly doused by a flash of recognition.  Could it be?  That
girl...  that hair...  her laugh, her smile...

   Sister Anne flung open the door.  "Julie!?!" she called out.

   "Sister Anne!" The girl smiled and jumped for joy.  She ran to the nun
and hugged her.

   Julie buried her face in Sister Anne's chest.  They hugged for what
seemed like hours.

   Sister Anne looked over at Earl.  He gave her a crooked smile.  His hair
was disheveled.  He lay on the floor still holding a doll in his hand.  He
didn't seem at all displeased.  Finally, Earl broke the silence.

   "Well, isn't this a happy reunion?" Earl said.

   "Oh, Earl," Sister Anne said.  "She looks so beautiful.  Thank you!"

   "Safe and sound, just like I promised," he said.

   Sister Anne held Julie and they talked a bit.  Julie did not seem the
least bit sad or homesick.  She showed Sister Anne her dolls and her
clothes.  After a while, the aroma of roast beef wafted into the room. 
Julie looked out in the corridor and spotted the cart.  Her stares did not
escape Sister Anne's notice.

   "Are you hungry, Sweetheart?" Sister Anne asked.  "Let me get you
something."

   She wheeled in the cart and began pouring a bowl for Julie.

   "Wait, Sister," Julie said.  "First, I haf'ta pay for it."

   Sister Anne watched in shock as Julie walked up to Earl and begin
unzipping his pants.  Earl stood in front of her and let the little girl
fish out his penis.  He looked on eagerly as she took his semi-flacid dick
into her mouth and began to suck.

   Sister Anne's body went numb as she watched with disbelief.  Julie and
Earl locked eyes.  The little girl never took her sky blue eyes off of her
captor as she took his filthy cock into her mouth.  Earl's odor was
pungent. It didn't take long for acrid scent of urine and dried cum to
reach Sister Anne's nose.  She felt the queasiness rise in her gut as Julie
licked Earl's bulbous cockhead.  She saw the little girl's tongue flick off
bits of cheesy smegma from under his glans.  Julie swallowed it eagerly,
all the while keeping her eyes on her master.

   Earl smiled his crooked grin as his cock grew in Julie's mouth.  It rose
slowly until reaching its full girth and hardness.  He gently stroked
Julie's cheek and ran his fingers through her silky blonde hair.  As his
cock hardened, his need for her grew.  He began pushing his cock into her
mouth, forcing her to take him deeper.  His his fat, darkly soiled hand
stopped caressing her flowing locks and wrapped around the back of her
head, forcing the child to take his swollen manhood into her throat.

   Julie never missed a beat.  Her beautiful baby blue eyes remained locked
on the face of her master.  Her tiny hand reached for his shaft, now
pulsating with the flow of blood.  She jerked him off eagerly as the bulk
of his cock disappeared into her mouth.  A sliver of drool began to leak
from Julie's tiny lips.  Her breathing became more labored as she struggled
to cope with his size.  She made slight gagging and gurgling noises as
Earl's thrusts became more aggressive, more violent.  He had found the back
of her throat.  A second hand gripped her head more tightly and he began a
ruthless face fucking.

   Thick strands of saliva were oozing from Julie's mouth now.  Her hair
was in disarray as Earl clutched her head like a ripe piece of fruit.  He
buried his massive phallus into the child's mouth, forcing his wiry mass of
black public hairs into her face.

   Julie lost her composure and tears streamed from her eyes, but she never
cried out or tried to pull away.  In fact, she gripped his waist tightly
and almost seemed to be pulling him into her.  It was almost as though she
were eager for him, eager for his cum.

   Sister Anne studied Earl's face intently.  His eyelids drooped lazily as
he kept his gaze fixed on Julie's face.  Beads of sweat rolled down his fat
cheek.  She could hear his heavy, labored breaths as he struggled to
maintain his rhythm.  His hips began bucking faster and faster.  He was
close, she surmised.

   Julie's face was so sweet -- golden blond hair, sky blue eyes.  Her tiny
lips parted for Earl's impossibly hard cock.  He watched as he buried
himself in her face.  He could feel the tightness of her mouth, the
roughness of the roof of her mouth.  He felt his muscles clench tightly as
his cockhead found the back of Julie's throat.  He pounded her face, hard
and fast.  He gave no care for her comfort, her pleasure.  His only thought
was to feed the growing desire to bury himself as far and as deep inside
her as he could.

   Suddenly, Earl belted out a sickening groan.  He grabbed Julie
forcefully by the head and heaved himself into her.  Her nose was buried in
a foul-smelling nest of public hair when she felt him cum.  Burst after
burst of thick, sticky cum shot down her throat, forcing her to gag.  She
tried to swallow it, but it was too much.  Cum dribbled from her mouth and
onto her blouse.  Earl's body spasmed again and again as he unloaded his
cargo into her.

   Finally, he released her and collapsed on the bed.  Julie coughed for a
moment, but quickly recovered.  She crawled up to him and licked his balls
clean.  She licked his shaft and sucked on the now-tender head.  She
cleaned him of all the sweat and cum, just as he had commanded Sister Anne
to do at the end of every session.

   "Now, we can eat," Julie said, smiling.  She helped herself to a bowl of
stew as Sister Anne stood frozen.  She was numb to the bone.  How long? 
she wondered.  How long had Earl been fucking Julie?

   The little girl ran playfully to the cart where her prize of cheap,
store-bought beef stew awaited her.  Her blouse was ruined, stained with a
combination of saliva and semen.  She clumsily filled a bowl and began
slurping from it, not even bothering with a spoon.

   Sister Anne collapsed in the corner.  She sat motionless.  She didn't
know what to feel or even how to feel.  Numbness enveloped her.  She felt
cold and distant.  Should she be happy to be reunited with Julie?  Grateful
that, with the exception of her innocence, she is unharmed?  Or should she
feel betrayed at Earl's lies?  Disgusted by his lust?  Or...  or...  or
jealous?  No!  No, of course she shouldn't be jealous.  What was there to
be jealous of?  So what if he shared his attention, his desire with Julie?
She was a little girl, a sweet, precious jewel.  She was something to be
cherished and loved, not to be jealous of.  No, Sister Anne quickly dashed
that evil thought from her mind and instead she chose to feel nothing.

   "Wanna go again?"

   Julie's sweet sing-song voice had woken Sister Anne from her thoughts.
Julie had peeled off her cum-stained blouse.  She stood before Earl
topless. Before he could answer, she was on him, sucking his cock.  Sister
Anne watched as Julie brought his manhood back to life.  She eyed the
girl's lithe figure.  She was just a wisp of a girl, so thin she was like a
stick figure.  Yet, the puffy little breasts of womanhood were just
beginning to protrude.  Her chest flared out abruptly to form barely
noticeable bumps.

   Julie yanked down her skirt as she sucked Earl's cock.  It was as though
she felt Sister Anne's eyes on her, studying her form.  Her ass was
absolute perfection.  Soft round cheeks swelled like rolling hills.  There
was no trace of blemish or deformity.  No unsightly hair or wrinkly fat. 
They were simply beautiful.  Even Sister Anne felt a stirring of lust
within her.  She looked at Julie the way Earl must have looked at her.  It
was awkward and uncomfortable, but she could not deny that the girl was
beautiful...  even sexy....

   Earl's massive hands wrapped around Julie's tiny waist and plumped her
on the bed.  Julie spread her legs and Earl's face found a home between
them.  His tongue parted the smooth, sweet lips of her womanhood.  His nose
inhaled the sweet perfume of her desire.  Tiny, barely visible, downy hairs
decorated her mound.  Earl's tongue found her tiny clitoris and played with
it.  He inserted it deep inside her and tasted her juices.

   He reached under the bed blindly until he found his quarry -- an unused
bottle of KY.  Sister Anne suddenly became aware of the scattered mess of
spent bottles of lube under the bed.  She eyed them, coldly realizing that
each one of them represented a fuck.  How long?

   Earl emptied the tiny bottle into Julie's pubescent cunny.  He hunkered
over her like a hungry giant, his massive phallus pointing toward her
forbidden pleasure hole.  Sister Anne noted the stark contrast between
them. He was a massive, lumbering beast -- hairy, sweaty, and fat.  His
cock was like a monster, thick and pulsating with bulging veins protruding
from beneath the skin.  Julie was so tiny, just a little girl.  Her skin
was pure white with no hint of a tan line or pimple or any imperfection. 
From her perspective, Earl's cock was almost the size of Julie's arm!  How
could he possibly enter that tiny wisp of a girl?  If he managed it, he was
so huge, his cock would fill her completely.  Sister Anne fought to push
back that feeling of jealousy again.

   Earl pushed the head of his cock against Julie's lips, forcing them to
give way.  He felt a tiny slit of heat and moisture press against his
purple head.  He knew he was on target.  The warmth of Julie's cunt
beckoned him forward.  He pressed into her, forcing her to open.  His
cockhead parted her tight, vaginal walls and he felt her body stretch to
accommodate him.  Julie let out a little grunt as Earl began to fuck her.

   Sister Anne hated herself, but she found that she was incapable of
controlling her body.  A warm rush flooded her loins.  Her hand moved of
its own will and began fingering her clit.  She moved to get a better view
so she could watch every detail as Earl's cock penetrated this impossibly
tight doorway.

   This tiny little girl looked so incredibly small compared to the massive
blob of a man that hunkered over her.  Earl's gut alone was bigger than her
entire body.  His cock looked absolutely massive as he buried it inside
her. How could she take something so big?  Sister Anne had trouble taking
it herself.  She felt a twinge of envy inside her.  How she wished she
could be as tight for Earl as Julie must be!

   Earl slammed his cock deeper in Julie.  His balls gave an audible slap
as they hit her ass.  He was well on his way to burying himself inside her.
The entrance to her vagina gripped him like a vice.  It was like fucking
into a clenched fist.

   Sister Anne peeled off her robe revealing her breasts.  A hand
unconsciously drifted to her nipple and began to caress it.  The other hand
was vigorously rubbing her clit, sending shockwaves of electricity through
her body as she imagined that she was the one Earl was furiously pounding.

   She felt drawn to him.  An unseen force compelled her to crawl to him on
her hands and knees as he continued to fuck Julie.  She found herself
licking his ass as he slammed himself into Julie's pussy again and again.

   "Don't think I've forgotten about you, Sister," he said.  "Oh no!  I
haven't forgotten you at all."

   He spun around, his cock wet and slick.  He aimed at her face.

   "Taste that, Sister," he commanded.

   Sister Anne obeyed taking his salty-sweet cock into her mouth.  She
caressed him with her tongue, lapping up all the sweat and juice.

   "Can you taste that?" he asked.  "That's what Julie's cunt tastes like!"

   Earl slid his cock back into Julie's tiny pussy...  with some
difficulty. Sister Anne tried to position herself so she could lick his
shaft as he drove in and out of little Julie.  Sister Anne licked him
desperately.  Her tongue flicked over crown of his cockhead as it made
brief appearances out of Julie's cunny.  The nun found her tongue lapping
Julie's clit and giving perverse pleasure to the child who was supposed to
be her ward.  Every once in a while, Earl would pull out and reward Sister
Anne with a mouthful of his cock.  Soon, the sheer tightness of Julie's
nubile body was too much for him.  He could feel her squeezing on him like
a vice each time he pumped into her.  The rhythm of his fucking grew
faster, more impatient as he desperately tried fuel his pending orgasm.

   Finally, Earl let out a bellow.  He pushed himself deep into Julie's
body.  His cock was impossibly buried up to the hilt.  He let out a grunt
every time a tidal wave of semen ran the length of his shaft and emptied
into the little girl's body.  Load after load of rich, potent semen pumped
its way into the child's budding vagina.

   "Put your mouth over her cunt, Sister," Earl commanded.

   He let his semi-erect cock pop out.  Like a cork being pulled from a
champagne bottle, the release of Earl's cock was followed by a gush of cum.
Julie's little body was too small to contain his voluminous load.

   Sister Anne quickly sucked up every drop as it poured from Julie's cunt
like a faucet.  She found her self mouthing Julie's cunt and lapping up
Earl's sweet love juice.

   "That's it, Sister," Earl encouraged her.  "Clean that shit up." He
stroked his semi-erect cock as he watched eagerly.  "Now, feed it to her.
Let Julie taste some of that."

   Sister Anne looked at him pleadingly, then to Julie.

   "It's okay, Sister," Julie said.  "Me and Mia do it all the time."

   Mia?  Earl had been having threesomes with Julie and MIa?

   Julie opened her mouth wide.  Sister Anne didn't know what to do except
obey.  She hovered her head over Julie's sweet face.  She was like a little
angel, her golden hair framed her face like a glowing halo.  Sister Anne
let a little cum dribble from her mouth into Julie's.  She drew her face
closer, drawn by the girl's sweetness.  Even now, after this sordid and
disgusting fucking, she still looked innocent.  Sister Anne let a little
more cum flow.  Julie took it eagerly into her mouth.  By now their faces
were almost touching, Sister Anne's mouth covered Julie's.  They shared a
loving kiss as Sister Anne allowed the cum to flow freely.  Julie eagerly
sucked the mixture of semen and saliva from the nun's mouth like a babe
sucking a teat for nourishment.

   Soon, their tongues were touching.  Sister Anne couldn't control
herself. She let her tongue explore Julie's mouth, tasting her sweetness
mixed with Earl's semen.  Julie's tongue likewise darted into Sister Anne's
mouth.  The two shared a sweet, intimate French kiss.  Teacher and student,
woman and girl, a mother and a daughter.

   Earl's cock grew harder in his hand as he watched the two kiss
passionately.  Sister Anne's naked chest pressed against Julie's budding
breasts.  The nun's face pressed against the little girl's lips.  Earl
stroked his cock to full erection.

   "Yeah, that's shit's hot," Earl said as he watched.  "Swallow that and
gimmee some o'that lovin'!"

   They broke their kiss and Julie swallowed the last of Earl's cum.  She
showed him her empty mouth as proof of her obedience.

   Earl shoved his cock toward their faces.  Both of his slaves descended
on it.  Sister Anne took the head in her mouth and Julie licked the shaft.
Sister Anne sucked him as hard she could, building up the pressure.  Her
tongue flicked the underside of his cock's head rapidly.  Julie ran her
mouth up and down the side of his shaft.  She licked his balls and his
inner thigh.

   Sister Anne abandoned the head and sucked on the shaft, running her lips
up and down the side of his cock.  The two sex slaves pressed their lips
tightly against his cock, running up and down its length.  Each trying
eagerly to please their master.  Each trying to outdo the other in an
unspoken competition.

   Sister Anne finally took Earl's cock in her mouth again.  She forced it
in as deep as it would go.  The head pressed against the back of her
throat. Her body convulsed involuntarily as she started to gag.  No!  She
was going to take this!  She was going to show him what she could endure
for him.  She was going to please him in a way this little girl never
could!

   She took him in deeper.  Her tongue hung out of her mouth and she made
her way down the shaft forcing him down her throat.

   "Oh!  Oh!  Oh!  It's SO TIGHT!!!" Earl cried out in pleasure, much to
Sister Anne's satisfaction.

   She took him deeper, gagging all the way.  Tears began streaming down
her cheeks as the pressure forced her eyes to water.  Finally her nose was
against his stomach.  Wiry pubic hairs tickled her face and stuck in her
nostrils.  She couldn't breathe.  She began to turn red.

   "Oh yeah!  Take that shit!  TAKE IT!" Earl bellowed.

   He grabbed her head in his hands and forced himself in impossibly
deeper. He jerked head back and force on his cock and began to fuck her
face in vicious little spurts.  In and out, he jammed his cock against the
back of throat, oblivious to the gagging and tears.

   The face fuck lasted only seconds as he felt his need building.  He
fucked her faster in regular, rapid thrusts until finally, he unleashed his
load.  He screamed as he came, letting Sister Anne choke and gag on his
cum.

   She pulled her face off violently and got to all fours, coughing and
puking up cum.  She coughed and coughed as cum spilled from her mouth onto
the floor.

   "Shit, woman!  You are one amazing fuck!  You always have to have the
last fuck, don't you?" he said approvingly.  "That's what I love about
fucking you."

   Sister Anne was still hunkered over, her face staring at the pool of
semen and saliva forming eerie patterns on the carpet.  Her lungs heaved
uncontrollably, throwing her in a coughing fit in an attempt to empty
themselves of the fluids that had just shot down her trachea.  Despite all
this, Earl's words rang through her head.  "That's what I love about
fucking you," he had said.  She did it.  She pleased him.  She pleased her
Master.

   "Now, clean that shit up," she heard Earl's voice bark.  "You know what
to do."

   Without a word the two girls began licking Earl's cum up off the floor.
Sister Anne looked at Julie with shame and sadness.  "What have I done?"
she thought to herself.  "How did it come to this?"

   Yet, despite herself, she couldn't stop.  She couldn't help herself or
help poor Julie.  She could only obey.

   ***

   "It's only coffee," he said.  His voice was warm and inviting.  "Come
on, Lara, just one cup."

   "Just one," she relented, smiling.

   She let the charming man take her by the arm and walk her to the diner.
Lara couldn't really afford a private investigator to help find Perdita now
that the police had stopped looking, but she found someone who was willing
to do a few little things cheaply.  She knew deep inside that he was only
doing it because he was attracted to her.  Somewhere inside, she let
herself feel attraction for him, too.

   They sipped their coffee, and laughed and talked.  They talked about
anything and everything...  except Perdita.  The sun set and the stars
began to dot the sky when they left.

   "Let me walk you home," he offered.  She couldn't deny him.  She wanted
his company.  It had been so long...  so long since a man wanted her. 
Phillip never forgave her for losing Perdita.  Now he was a shadow of
himself.  She couldn't bear to see him wasting away in the hospital....

   "I guess this is good night," her companion whispered huskily.  His
voice breaking her train of thought.  He drew closer to her.  She felt the
warmth of his body.  She knew he wanted to kiss her.  She wanted it too...

   "No!" she shouted abruptly.  "No, I can't!  I...  I'm still married... I
can't!  I can't betray my husband!  I'm loyal!  I'm loyal to him!"

   ***

   An orgasmic scream woke Sister Anne.  The fragment of her dream was
still fresh in her mind.  Earl, with one of his conquests, no doubt.  She
listened.  It wasn't just any one of his conquests.  It was Mia.  Why did
he keep her?  The thought of Earl sharing Julie with her stuck in Sister
Anne's gut like a dagger.

   And what of poor Julie?  Sister Anne's sacrifice had been for nothing.
How long?  She remembered asking him.  "Hell, she broke the day after she
got here!" he laughed.  Her deal with him -- to be his sex slave to
guarantee Julie's safety -- it had all been a lie.

   It didn't matter.  It didn't matter how she got here.  She was here. 
She couldn't stop obeying him, pleasing him, fucking him.  She belonged to
him.  She was his property.  She felt more purpose, more fulfillment than
she ever did as a wife, a mother, or a nun.  This was her place.

   But Mia....  how she hated Mia!  The other girls came and went, but Mia
remained.  Earl would take her night after night.  Her gut twisted knowing
that he was taking her right now.  She imagined his cock inside Mia's body,
filling her with cum.  Was Mia pregnant?  Sister Anne's hand went to her
belly.  It was visibly swollen now.  She could feel the baby inside her.
   Mia has to go.
