   The girls' continue their sex games.

   ------------

   Emily and Sara could no longer help it and they went after each other
voraciously.  Their lips locked as their tongues collided, their bodies
pressing against each other hard, grinding into each other while their
hands worked frantically to free each other from their clothing.  Finally
free of their garments, Sara pushed Emily down at the foot of Anna's bed
and climbed on top of her, her knees on either side of Emily's head.  She
teased Emily briefly by lowering her hips until her pussy was in reach of
Emily's tongue, and then pulling it back up just as her tongue almost made
contact.  Eventually she thrust her hips down and started grinding on
Emily's face before sinking down herself to taste her lover's now wet
pussy. The girls ate each other in this sixty-nine position until both had
cum and they had been licked clean.  Anna watched with interest and arousal
this show that was being put on at the foot of her bed.  Her pussy was
burning with desire but she couldn't reach down to touch it.  Instead she
was grinding her hips up and down, enjoying the feeling of the poo in her
full diaper sliding this way and that, caressing her skin and working
itself inside her labia, massaging every inch of her young pussy, caressing
her clit like a lover's tongue.

   Soon enough and Anna was having an orgasm after grinding her hips and
watching her sister eat out her lover.  She tried her best to keep it
quiet, but couldn't help as a small moan escaped her lips as her body
shook. This caught Emily and Sara's attention.  "Did baby like that?" asked
Sara, her hand moving over to Anna's perfectly shaped calf.  "I don't
suppose we should punish her for that, as we were putting on quite the
show."

   Emily nodded in agreement and smiled.  She crawled up the bed towards
her filthy little sister and undid the straps on her hips which were
holding her diapers on.  They fell forward as Anna spread her legs,
exposing the beautiful young naked pussy, completely covered in poo.  There
was a large mass of it between her legs, and every part of her skin was
brown, streaked with the gooey mess.  "Does baby want another?" Emily asked
as she lowered her head towards her baby sister's burning cunt.

   Emily's tongue worked its way into her sister's gorgeous mound until she
found her aroused clitoris.  She winced at the taste of her sisters shit,
but as long as she only used the tip of her tongue she thought she would be
okay.  Sara in the mean time spread her legs and began masturbating at the
sight of the two, loving sisters.  It only took a few minutes before Anna
was moaning loudly with pleasure.  As her climax came she bucked her hips
directly into Emily's face, smearing shit that had been on her cunt and
thighs all over her big sister's pretty face.  As cum poured out of her it
forced some poo that had been trapped inside her vagina out and it slid
with ease into Emily's mouth.  The bucking had surprised Emily and just as
the poo entered her mouth she swallowed and she froze with horror as she
felt the poo sliding down her throat.  She wretched but nothing happened.
She wretched again and vomit started spewing from her mouth, which Emily
aimed so that it would cover her little sister.

   Anna's taught stomach and muscular thighs were soon soaked in Emily's
puke, as was her perfect pussy and hips.  Sara didn't want to be left out
of what looked like fun, so she stood up on the bed and made her way over
to Anna, putting her feet on either side of the little girl's stomach. 
Emily smiled as she saw Sara bring a hand up to her mouth and shove her
middle fingers as far into it as she could, tickling the back of her throat
and forcing her gag reflex.  Soon she was throwing up all over Anna's head,
face, and chest.  Bits of undigested pizza mixed with the other things in
her stomach and came out all at once.  Anna's hair was now soaked and she
sputtered, gasping for air as the warm mess slid down her face, covering
her nose and mouth.

   Sara and Emily stood back and admired their handiwork, the sight of the
young girl tied to her bed, laying in a mess of shit and vomit, with a
little clear cum dripping from her preteen cunt was very erotic.  Just then
Sara remembered something and ran to Emily's room to grab it out of her
bag. She came running back holding a medical enema bag.  "It's my mom's"
Sara explained, "I thought it could be fun." Emily agreed that it might be
fun, and caught herself for a moment imagining Sara's gorgeous mother on
her hands and knees, her huge tits swinging down, almost touching the
floor, working the tube into her asshole - that was a sight Emily would
like to see.

   Sara had unscrewed the tubbing and was scooping handfuls of Anna's mess
into the bag.  Shit and vomit mostly, the bed surrounding Anna had become a
soupy mess.  She filled the bag and then screwed the cap with the tube back
on and grinned at Emily.  "You first sweetie." Sara watched as Emily got
onto her hands and knees, her head facing the foot of the bed.  She spread
her knees out so that Sara would have easier access, and so that Anna would
have a wonderful view of her big sister getting filled with her mess.

   Sara worked the end of the nozzle into Emily's puckered ass hole,
lubricating it first with her tongue.  When it had gone in a fair ways she
began to push on the bag, and she watched the expression on Emily's face as
she began to feel her insides being filled to the breaking point.  It got
to the point where Emily couldn't take any more, her bowels hurting with
the pressure.  Quickly Sara pulled the hose out and handed it to Emily as
they switched positions.  Once Sara was full with the remaining mess Emily
bot back up on the bed so that they were both on their hands and knees,
heads facing the foot of the bed, and their young plump asses aimed at
Anna. Emily and Sara moved close together and began to make out as each put
one hand down between their legs.  After a few minutes of kissing and
masturbating (all this time making Anna quite horny, for she had an
excellent view), the two girls could take the pressure no more and they
released their clenched anuses.  Anna was quickly covered in muck from both
of the girls' bowels.  Along with the liquid sludge that they had put in
there, large chunks of poo slid out and landed on Anna.  Emily and Sara had
been holding their poo in for days and now it all came out.  They rubbed
their clits harder and as the last few trickles of vomit and shit rand down
from their assholes and into their pussies, they climaxed together before
collapsing on the bed, writhing around and making out in the afterglow of
their magnificent orgasms.
