Subject: Mutual Desire Chapter 3

Mutual Desire
By Sam B.

You should not read this story if you are under 18 or 21 in some states. You
should not read this story if graphic acts of lesbian sex between siblings
offends you. The contents of the story are entirely fictitious and I do not
condone or in any way support these actions in real life. Yeah, you've heard
it all before. On to the story.

Oh, okay, one thing to note. There are some major pissing and shitting
elements towards the end of this chapter. I caved to those who wanted some.
I do not promise any continuation of this. This is likely a one-time treat
you guys. If you don't like that stuff, just skip over it. The final section
of the chapter will take place after, and those bits are not really critical
to the story.

Chapter 3: Let's Get Physical

Kari returned Sam's wicked grin with one of her own. "I dunno," she said.
"What do *you* want to play with first?" Sam leaned forward in response and
licked Kari's chest from just between her two large breasts where her blouse
was unbuttoned up to her chin. Kari shuddered.

Sam unbuttoned her own blouse, and removed it, revealing her big breasts,
one of which she brought up to her mouth to lick herself. Kari joined her
seconds later, and the two worked the breast over, and then the other one
their tongues clashing every now and then. Kari soon had removed her blouse,
and the two sisters gave her breasts the same treatment. Sam seductively
unlaced one of the boots and removed it. Kari leaned down and nibbled
lightly at her toes. Sam's feet curled up as she moaned lightly. Kari
repeated the process with the other boot. Sam was lying on her stomach, her
large breasts mashed against the carpet. Kari reached up and unbuttoned
Sam's shorts, quickly pulling them off, leaving her sister's tight, round
ass exposed.

Kari traced a finger down Sam's back, and she arched it in response. After a
few seconds, the feeling stopped, and then she felt her arms being grasped
and pulled behind her. A few seconds later, she felt the soft feeling of
silk tying them together. "Kari, what—" she began, but Kari shushed her, now
working on tying her feet together at her ankles. "What are you going to do
to me, Kari?" Sam asked, enjoying how kinky she felt being tied up.

Kari smiled down at her, then leaned down to lick the back of her sister's
neck. "Whatever I want to, Sam." She laughed between licking. "For the next
hour, you're going to be my little slut." Sam giggled with excitement. "And
then we'll trade," Kari said. "For the hour after, I'll be your slut." Sam
nodded eagerly. The first thing Kari did was strip off her jeans, leaving
her just as naked as her sister. She sat down a few inches above her
sister's head, and grabbed Sam's shoulders, pulling her up. Kari slid
forward, and let Sam's head fall in her lap. "Bring me to orgasm, slut," she
said in her best commanding voice.

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



Samantha laughed, and reached out with her tongue, gently caressing the
folds of her older sister's pussy, making sure to flick the clit at the end
of it. She wriggled herself forward slightly to give her a better angle at
it, and began to alternate between shoving her tongue in as far as she could
reach and wiggling it around, and flicking Kari's clit, occasionally giving
it a light nibble. Kari writhed in ecstasy, holding the back of Samantha's
head in place, as perspiration began to bead on Kari's tanned and toned
body, collecting on her breasts, a few droplets sliding down between the
two, across her lightly visible abs, to pool in her navel, until it finally
collected enough to run down to where Samantha was tongue fucking her.
Samantha felt the liquid touch her nose, and she arched her back as much as
possible to lick up her sister's toned stomach, grabbing as much sweat as
she possibly could, loving the salty taste so similar to and yet so
different from her sister's pussy juice.

Kari quickly grasped Samantha's shoulders and forced her back down, and the
younger sister went back to eagerly tonguing Kari's sopping pussy. Kari's
hands were gripping her sister's brown hair tightly, though she was careful
not to pull hard on it; she didn't want to hurt her sister after all. She
was thrusting her hips towards her sister's face, her stomach rapidly
flexing and unflexing as she moved back and forth in time with her sister's
tongue. Her breaths came more and more shallowly, more and more rapidly as
she approached the moment of climax. Finally, with a long, protracted
scream, she came, her pussy exploding all over her sister's face, and as
Samamtha arched her back again, the cum gushed out over her shoulders and
breasts. She released her grip on Samantha's head and fell backwards.

With extreme effort, Samantha rolled over onto her back, her hands still
tied behind herself, and her feet still tied together at her ankles. She
licked eagerly around her lips gathering as much of her sister's sweet honey
as she could. She could hear Kari still twitching with post-orgasmic spasms
every now and then, while Sam stared down her chest at her breasts and past
them at her own pussy, looking inviting, but also unreachable due to her
restraints.

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

Kari finally regained control of her muscles, and forced herself into a
sitting position, still breathing heavily and sweating. Sam was on her back,
still nicely tied, thrusting her pussy into the air, as though trying to
fuck something that wasn't there. Kari smiled gleefully. "Was that good for
you, slut?" she asked, getting a thrill of excitement out of addressing her
sister in such terms.

"Yes, Kari," Samantha said.

Kari leaned over to her sister and grabbed her face. "For the next," she
glanced at the digital clock near her parents' bed, "forty-five minutes,"
she continued, "address me as 'mistress', or 'mistress Kari', understood?"

Sam nodded. "Yes, Mistress Kari," she said, bringing another wicked smile to
Kari's face.

"You want some relief, don't you slut?" Kari said, her wicked smile
broadening across her face. "You want me to fuck you, no?"

Sam nodded again. "Yes, Mistress Kari," she panted. Kari kept her smile on
her face as she looked evaluatively at her sister, watching the rise and
fall of her firm, cum-covered breasts, her firm, tanned stomach with more
than just a hint of muscular development, and her long, strong legs. Finally
she nodded, and Sam's face broke into a smile. "Thank you, Mistress Kari,"
she said, meaning every word.

Kari looked at the sex toys, and finally selected a large strapon dildo,
about ten inches long that had a short four inch dildo on the inside that
would go into Kari while she was fucking Sam.

--------

Samantha looked a little apprehensively at the strapon, but she would be
damned if she was going to stop her sister now. She desperately wanted,
needed, to be fucked. She had lost her virginity a year before when she had
been exploring herself with the handle of a hairbrush, so she knew that she
could take it, though it would stretch her. She knew that a ten-inch dildo
would hardly be a challenge to her sister, after all, Kari had taken
Samantha's entire fist earlier that day. The younger brunette smiled at the
memory.

Kari chose that moment to begin. Her breasts rubbed lightly against
Samantha's, causing both of them to give a slight moan as their nipples
stiffened form the stimulation. Kari rubbed the head of the dildo up and
down Samantha's wet slit, preparing to slide it in. She paused, reached down
to slide a few fingers into her sister's pussy briefly to make sure she was
ready, then she pushed forward.

Samantha's mouth formed an "O" shape, as she gasped. It was so large, and it
was stretching her pussy lips like they'd never been stretched before.
"That's right, slut," Kari moaned. "It's big, isn't it? Well, you asked for
it, and I'm gonna fuck you dry." Finally, Kari was lying with her hips
against Samantha's, all ten inches buried in Samantha's fifteen year-old
cunt.


Then she pulled out nine inches, Samantha moaning with every inch that was
withdrawn. After hovering for a moment she slammed it back in. Then she was
fucking her little sister like a wild animal. Samantha was moaning
constantly, and thrashing about, unable to do anything to slow Kari down.
She heard Kari growl and looked up. Her sister's teeth were bared and she
was drooling. As Samantha watched droplets fell from Kari's mouth onto
Samantha's neck, just above her breasts. Kari had completely lost control,
and she was still fucking with wild abandon, Samantha could feel the huge
ten-inch rubber cock moving in and out of her tight pussy.

She felt heat building in her loins, Kari still was not slowing, both bodies
were glistening with sweat, and Samantha's with a copious amount of Kari's
drool. Samantha threw back her head and screamed, long and loud as she
orgasmed powerfully. Kari kept fucking her, and even before she had come
down from her first climax, she felt another orgasm building, still more
powerful then the first. She drew in breath hastily and screamed again as
her body bucked up and down. Her cum sprayed out of her pussy powerfully,
spread aided by the cock her sister was still ramming into her.
Unbelievably, Samantha felt herself building to a third climax. This one
would be huge. She couldn't draw breath, she couldn't scream, she just shook
uncontrollably, bucking her whole body off the ground several times as cum
shot like a geyser from her pussy. Kari had finally pulled out of her, and
she saw and hear several spurts hit her sister. She was still shaking
uncontrollably, and moments later she passed out, spent.

-----------

Kari saw her sister pass out, and she grinned down at the motionless body
below her, cum and sweat soaked the entire front of her body. Kari reached
down and rubbed her sister's cum where it had struck her. She still couldn't
believe that her sister had shot so far and so powerfully. Kari had never
seen an orgasm like it. Of course she hadn't ever had sex with anyone else
before, so it wasn't surprising. She wondered if she was capable of it. She
might found out when she was Sam's slut. She giggled lightly, stifling it
with her hand. She spread the cum from Sam across her breasts, moaning as
they swelled slightly and the nipples stiffened. She fingered herself to a
quick orgasm, letting the cum spatter down onto Sam. With a sigh she untied
her sister's bonds. She would need a shower.

Getting Sam to the bathroom proved a little bit difficult, but finally by
placing her onto a towel, Kari found a way to drag her without giving her
rug burn, and once they reached the bathroom, it was no longer needed.
managed to get Sam lying down in the shower stall, but she didn't want to
turn on the water until Sam woke up, so she contented herself with watching
the rise and fall of her sister's cum-soaked breasts.

Finally Sam stirred, feebly opening her eyes. "Oooh, K-" she stopped.
"Mis... mistress Kari," she corrected herself. Kari looked over at the
clock. For about ten more minutes. "I can't really... move..." Sam said.
Kari smiled and stepped into the shower moving to turn on the water, then a
wicked thought occurred to her. Something so depraved that she couldn't
believe she was thinking of it.

"Sam," she said. "I'm going to turn the water on in a minute or so. But
first I'm going to wash you off." Sam feebly stirred, and looked up at Kari,
a questioning look in her eye. Kari smiled. "I'm going to give you a golden
shower."

Sam looked confused for a moment, then comprehension dawned. "You're going
to piss on me?" she asked. Kari had expected her to look disgusted. On the
contrary she looked excited. "Oh man, I love being your little slut, sis!"

Kari laughed. "All right then slut, get ready for it!"

---------

Samantha looked up at her sister expectantly, waiting for the promised
actions to begin. Finally, after what seemed like an eternity, a stream of
piss erupted from Kari's puss, to soak Samantha's abdomen, washing some of
the dried cum off. Immediately the smell of piss permeated the air, but
Samantha didn't care. She watched the stream of piss as it moved up her
body, splashing her breasts now. She closed her eyes and opened her mouth.
She gagged as the first of it hit her mouth. It was salty, she hadn't
expected it to be so salty, but she swallowed, and after the first mouthful,
it wasn't so bad. She had swallowed just three mouthfuls when the stream
moved back away from her mouth, and splashed over her tits and abdomen
again, washing off more dried cum.

Finally the stream slowed and stopped. Samantha looked up at her sister with
adoring eyes. "Oh my God, Kari," she said. Kari was looking down at her too,
looking extremely aroused.

"That was incredibly sexy, Sam," Kari said. Samantha nodded.

Kari moved to turn on the water. "Kari, wait," Samantha said. Kari paused.

Samantha lowered her voice and mumbled something that Kari couldn't make
out. "Pardon?" Kari asked.

Samantha flushed red. "You can..." she trailed off, then looked up at Kari
and spoke more forcefully. "You can shit on me, if you want," she said.
Kari's mouth dropped open in surprise and shock at the dirtiness of this
idea from her sister. "I mean, I'm going to take a shower anyway.... It'll
all come off." Kari opened her mouth to ask a question. Sam gave a firm nod.
"Yes, I'm sure. Shit on me, Kari," she said.

Kari nodded and crouched down, facing Samantha, over her abs. Samantha
watched Kari's face go slightly pink as she squeezed, and moved her eyes
down to watch the turd as it slid out onto her stomach. Kari was not done
there. She moved up a little, and Samantha watched in mounting excitement as
Kari squeezed out a second long turd between the mounds of Samantha's large
breasts. She looked Samantha in the eyes an unspoken question obvious, and
the young brunette nodded firmly without hesitation.

Kari turned around and position her asshole over Samantha's mouth. She
squeezed out a final, much smaller turd that dropped into Samantha's mouth.
The younger sister rolled it around on her tongue. It didn't taste at all
like it smelled. It was salty, and very different. The texture of her
sister's shit was actually not that unpleasant. She chewed it a little bit
and swallowed it.

She looked up. Her sister's ass was still positioned over her mouth. She
propped herself up just slightly on her elbows and acted as her sister's
toilet paper, licking Kari's ass clean with gusto, swallowing the little
bits of turd. that still clung to the crack of her sister's shapely ass.

Finally Kari stood up straight. She looked down at Samantha, her hair soaked
with her sister's piss, her chest covered in her sister's shit. "My God,
sis," she said. "You are one dirty slut." Samantha looked up at Kari and
grinned wickedly. "Thanks, Kari," she said.

----------

As they lay together on the bed, late that night, no sheets covering their
naked forms this time, Kari looked over at her sister. She rolled onto her
side, reached out and caressed her sister's cheek. "So why didn't you take
your turn as my mistress?" Kari asked.

Sam rolled herself onto her side to return the caress. "I dunno," she said.
"Maybe I will later. I guess I just didn't feel... dominant... after letting
you do those degrading things to me." She reached out and caressed one of
Kari's large breasts. "I enjoyed them," she said with a smile. "But that
doesn't mean they weren't degrading." Kari smiled and nodded.

She hesitated a bit with what she was going to say next. "I thought," she
said. "That I was going to end up as your willing slave," she said. "You've
always had such a forceful personality, and there's no doubt you know what
you would have to do to get me to obey you without question."

Samantha scooted in closer to her sister. "That's true," she said. "But I
don't want you as my slave. At least, not right now. I just want you as my
lover."

Kari kissed Sam deeply, Sam returning it. When they pulled apart, she
smiled. "I love you Sam. For more than just your body."

Sam smiled at her. "You can love me for just my body if you want," she said.
"I don't really care as long as you keep fucking me." She winked at Kari. "I
love you too," Sam said. "For more than just your body." She smiled. "But
come on. Enough mushy talk. Let's fuck."

Kari smiled and laughed. "I can agree to that!" she said, and she rolled
over on top of Sam.

End Chapter 3....

Okay, I gave some of you what you'd been wanting. I went a lot farther than
I like to see in stuff I read, but don't expect something like that again.
As always, comments and suggestions will be appreciated. If you didn't like
the pissing and shitting, please, don't bother to mention it, and
concentrate on the other aspects of the chapter. (If you did like the
pissing and shitting, you're welcome to mention it.) I just know there are
people who don't like it, and I'm actually one of them. But I decided to
broaden my writing horizons. Guess this southern girl can get pretty dirty
when she wants to. As always, write these comments to
