Julia
Part 4 (Lessons in Filth)

by Mythos

   Mondays and Thursdays. Those were Evelyn's rugby days. Lily
normally arrived home two hours before Evelyn and got dinner
ready. Now, that was Julia's time. The first day was Thursday.
As directed, Lily waited on the steps outside her school.

   Julia arrived from cheerleading practice around four. Lily
gathered her belongings and hurried to her.

   "Hiya," Julia said.

   "Hi."

   "We gotta move fast. My house is in the opposite direction.
Wanna run?"

   "Sure."

   They jogged half a mile to Julia's home. Neither of her
parents' cars were in the building lot. Good. Her parents were
due back until after Lily would leave, but every now and then
one stayed home.

   "Here we are." Julia fetched her keys. "Are you looking
forward to this?"

   "No."

   Julia stared at her, then remembered. "Ohh, right. You're not
allowed to lie to me. That's okay. I'm here to make you enjoy
this stuff. We're gonna have fun." She opened the door and
ushered Lily in. "I'm not going to do any of that master-slave
punishing stuff. I'm not into that."

   "But," Julia said as they headed upstairs, "You still need to
obey my orders. Evelyn wants me to report back for every
session. She wants to know if you're disobeying me. Cool?"

   "Cool."

   In her bedroom, Julia rolled her carpet aside and fetched a
plastic tarp, which Lily helped her lay out over the floor. Once
done, Julia closed the door and sat in the middle of the tarp.
"Join me," she said.

   Lily set her book bag aside and sat before Julia.

   "So. Today I thought we'd just talk. Maybe we'll do something
dirty later if we're up to it. That sound cool?"

   "Yeah," Lily replied.

   "Good. So, what's the grossest stuff you can handle?"

   "I sometimes clean people's cocks after they do me in the
ass. That's usually the most I ever do."

   "That's all? What's the grossest thing you've ever done?"

   "A couple months ago, I was fisting a woman's ass. My hand
got covered in her poop, and she made me lick it clean with her.
I threw up. Evelyn caned me pretty hard when we got home."

   "Does she cane you a lot?"

   "Yeah, but that time was really hard. I've tried a couple
more times since then, but I always throw up. We haven't tried
for a while. Evelyn sort of dropped it. "

   "Then I come along and convince her you should do this more.
You probably hate me, don't you?"

   "I don't hate you. I want to be able to do to this."

   "Really? Why?"

   "Evelyn wants me to be able to do that kind of stuff. She
hasn't booked any more shows with that other woman because she
doesn't want that woman upstaging us again."

   "This woman eats poop too?"

   "Yeah. She's better at it."

   "And she took a fist up her ass? Who is she? She sounds like
my kind of girl."

   "I'm not allowed to tell you. Sorry."

   "That's fine. Do you think I'll get to meet her sometime?"

   "Maybe."

   "Does this woman know that Evelyn gave you to me to train?"

   "I think so. This woman kept offering to train me herself,
but Evelyn doesn't want that. It's a pride thing. Evelyn said
she was instead going to sell me to the sickest pervert she
could find to break me of my squeamishness. She'd buy me back
after he'd force fed me unspeakable amounts of poop and I could
eat it on my own.."

   "That sounds fucking hot."

   Lily smiled. "I guess you're going to be the pervert."

   "I wonder why she doesn't train you herself. I'm not going to
be nearly as strict with you as she would be."

   "She doesn't likes doing this kind of stuff herself. She
mostly wants me to do it so she can give me to more depraved
clients. And so this other woman doesn't upstage me again. I was
really surprised when she pooped for you."

   "I'm glad she did. I think the sight of her pooping is hot. I
would honestly love nothing else than for her to use me as her
toilet every day."

   "Really?" asked Lily. "You'd want that?"

   "Have you _seen_ your sister? You're lucky you get to be her
slave."

   "Yeah, but isn't it still gross?"

   "Gross? Yeah. But that's kind of what makes it hot. It's
taboo, and dirty. Everybody likes that to some level. People
like anal sex, or panty sniffing, or having sex when they're all
sweaty. I'm just like that, but a thousand times more about the
dirtiness. I'll do things that are gross just because they're
gross, and it'll turn me on. Once I ate poop out of a toilet
without knowing who's it was.

   "Really?"

   "Yeah. Couple years ago my parents took me to the skating
rink. I went to the bathroom and found out that the toilet was
broken, but several people had peed in it, and at the bottom was
a half-dissolved lump of poop. I stood there for, like, an hour
until I worked up the nerve to reach into the toilet and take
the poop out. I licked and sucked it. It was so mushy that it
dribbled down my arm."

   "And you didn't throw up?"

   "Oh, I threw up all over the place. I made the bathroom waaay
messier."

   "But you still enjoyed it?"

   "God, yes! Even as I threw up I was rubbing myself. And I've
masturbated so many times thinking back on it."

   "Why?"

   "Because I'm a sick puppy, that's why."

   "And that's what you want me to become?"

   "Well, my goal is to help you embrace the dirtiness of sex,
and maybe help you appreciate your sister more. You think you
can do that?"

   "Yeah. Think so. I was kind of hoping you'd help me with
other clients too.'

   "Really? You want that?"

   "It'll make Evelyn happier."

   "Wow. Aren't you the dedicated sister. All the more fun for
me." Julia hopped onto all fours. "Let's do something sexy.
Shall we?"

   Lily nodded.

   "Still feeling nervous?"

   Again Lily nodded. Julia leaned forward and kissed her. Their
tongues played in each other's mouths as Julia pushed Lily onto
her back and climbed on top of her. She peeled off the top of
her cheerleading uniform, unclasped her bra, then lowered onto
Lily. Entwined with each other, Julia pulled Lily's clothes off
one by one until the girl was naked beneath her. She made a
trail of kisses down Lily's body to her pussy, and slipped her
tongue inside Lily's slit.

   Lily writhed in pleasure. Julia didn't let up until Lily was
whimpering. Stopping, she climbed up and hugged Lily close.
Their breasts pressed together.

   "Feeling better?"

   Lily nodded against her shoulder.

   "Then how about we step things up. Let's play the game:
_who's going to eat who's poop_."

   "I'm going to eat yours?"

   "Wrong!"

   Confused, Lily frowned.

   "What?" asked Julia. "You thought I was going to throw you
into the deep end? I'm here to show you how to _enjoy_ it. So
we're starting off slow." She smiled. "And maaaybe I'm doing
this whole thing just because I want to have fun with you."

   Lily smiled. Julia rolled onto her back and motioned to Lily
to get over her. Lily knelt over Julia's face, positioned so she
could look Julia in the eyes. Julia licked Lily's asshole like a
dog.

   Lily looked unsure of herself.

   "Yes?" asked Julia.

   "I um... I have to pee first."

   "Oh right." Julia fastened her mouth over Lily's urethra. It
took Lily nearly a minute before she could relax enough to let
loose. When it came, the stream was a gentle dribble which Julia
easily drank down. When she finished, Julia refastened her mouth
to Lily's anus. For nearly two minute, all Lily did was flex her
sphincter in and out.

   "I can't," said Lily.

   "But you do have to, right? I told you save up."

   "I do. I'm just embarrassed."

   "Don't be. You're just like your sister: beautiful and sexy
with looks most girls would kill for. I can't believe how lucky
I am that I found you two girls. Millions of men and women who
would pay money to be where I am. They'd watch you pooping for
their porn. Take your time. The whole reason we're here is to
help get you comfortable with all this."

   Lily was blushing.

   "Does it help when I do this?" Julia ran her tongue along
Lily's rim, then stabbed into her hole.

   "No."

   "Okay. I'll stop. Just take your time."

   And Lily did. It took her nearly five minutes of her anus
pushing in and out before finally it widened. A single nugget of
poop fell into Julia's waiting mouth, and then the anus closed
back up. Julia mashed the piece with her tongue, allowing the
flavor to fill her mouth. She lifted her own butt off the floor
to pull off her cheerleading skirt, then rubbed herself as she
enjoyed the morsel.

   With her mouth still coated, she looked up at Lily. "Any
more."

   Lily nodded and scrunched up her face. Her expression was
adorable. Watching Lily, Julia nearly missed Lily's hole opening
back up. She opened her mouth just in time for a torrent to pour
out. An enormous length of creamy shit poured out of Lily,
overflowing Julia's mouth instantly. Lily's bladder released
again and piss shot into Julia's eyes and soaked her hair.

   Julia squealed.

   Lily immediately clamped her bladder and colon. "Oh my God!
I'm sorry." She clambered off Julia.

   Julia propped up on her elbows and blinked the urine out of
her eyes. The shit that had piled on top of her mouth fell onto
her breasts. With her mouth stuffed, she spent a minute slowly
chewing the mass and swallowing it down bit by bit.

   She finally swallowed the last in her mouth. "That was
unexpected." She swiped her finger along her cheeks to collect
any remaining shit.

   "I am so sorry."

   "No biggie. I'll just jump in the shower after we're done,
but you're going to have to work on your pelvic floor. You know
what I mean?"

   Lily shook her head.

   "Your muscles. You have no control over them. And not just
getting over nervousness. You need to learn how to poop while
holding your bladder."

   "Is that even possible?"

   "Yeah. It's two different sets of muscles. I can do it. And
your clients will like it if you can to. I'll teach you some
exercises you can do on your own time. Otherwise, we're done for
today." Julia picked a piece of shit from her breasts and popped
it in her mouth.

   "That's it?"

   "Yeah. I'm not going to make you do anything else... unless
you want to."

   Hesitating, Lily nodded.

   "Then why don't you come give me a kiss."

   Lily crawled forward, bringing her mouth inches from Julia's.
She paused at the smell of Julia's breath, but slowly, she
closed the distance. Their lips met. Any reservations Lily had
melted away. They kissed passionately. Julia entwined her hands
in Lily's hair.

   They pulled away breathless and stared into each other's
eyes.

   "I would keep you for myself," said Julia, "if you weren't
already your sister's"

   Lily smiled. Her gaze went from Julia to the mound of shit on
her breasts. Julia followed her gaze. She picked up a piece and
popped it in her mouth, then stared at Lily with daring eyes.

   Lily kissed her again. After entwining their tongues, Julia
pushed the lump into Lily's mouth.  Lily recoiled, but only
briefly. She pressed her lips back and returned the lump to
Julia, who chewed and swallowed it. Lily kissed a line down
Julia's chin and neck to the pile remaining on her breast. She
lapped up another clump and pressed her mouth again to Julia's.
They passed this one back and forth, letting it dissolve.

   Julia smeared the remainder of the pile over her chest. When
Lily lowered down again, she licked Julia's breasts clean of the
shit. Whenever she succeeded in cleaning one boob, she'd move to
the other, and Julia would resmear the clean one with her dirty
hand. Back and forth Lily went, until finally she gagged. She
tried to continue, but Julia stopped her.

   She pulled Lily to the ground and interlocked legs with her.
They ground their cunts together until both girls shuddered in
orgasm.

   Afterward, they lay breathless on the plastic tarp. "How do
you feel?" asked Julia.

   "Sick to my stomach," said Lily. "But still a little turned
on."

   "A perfect way to end it. Let's clean up and get you home.
