Mutual Desire
By Samantha B.

You should not read this story if you are under 18 years of age or 21 in
some states. This story contains graphic descriptions of lesbian sex acts
between siblings. The contents of the story are entirely fictitious, and I
do not condone these actions in any way, shape, or form. Now on to the
story.

Chapter 4: Moving Fast

Samantha stretched luxuriously in bed, arching her back and thrusting her
large, firm breasts upwards. She let herself lie flat again and opened her
eyes, looking at the rays of sunlight falling across her tight, tanned body
lying naked on the bed. Her sister, as usual, had awoken earlier. Samantha
smiled as she sat up on the edge of the bed and yawned, again stretching.
She stood up and walked to the door, taking just a moment to check the time.
It was a little before ten. When she got downstairs, breakfast was waiting
for her, as was Kari.

"You've finished your breakfast already," Samantha said, noting that Kari's
plate was already empty.

Kari nodded and smiled seductively. "But now I've got something else to
eat," she said. Samantha giggled and sat down at the table. Kari crawled on
her hands and knees to get under the table. "Spread your legs and scoot in,"
she said. Samantha did as Kari ordered and began to eat. She gasped
involuntarily as she felt her sister's tongue run the length of her cunt and
flick her clit. As she ate, she began to leak more and more, and shudder
more and more, gasping and moaning between, and sometimes during every bite.

Finally, she felt the heat in her lower stomach building up, and she knew
she was past the point of no return. She stretched her legs out and clamped
Kari's head between her strong thighs, and exploded, letting out a loud
scream of ecstasy. Her beautiful ass, slicked slightly with the perspiration
that had built up slipped off the chair, and she slid to the ground, next to
her sister. The cum soaked face and shoulders and the blonde hair plastered
to it had become a common-place enough picture in Samantha's mind that she
hardly noticed it.

She leaned in and began to lick Kari's giant breasts, first one and then the
other, alternating rapidly before settling on the right breast and suckling
the beautiful nipple into her mouth. Kari fell back, moaning, and Samantha
went right with her, keeping the nipple in her mouth, gently nibbling it
between her teeth. She reached down with her free hand, and felt Kari's
pussy. It was sopping wet and dripping. She slipped three fingers in with
ease, and added a fourth without too much difficulty, pumping them in and
out of Kari's dripping cunt.

She switched her focus to Kari's left breast, and formed the duckbill with
her formerly unoccupied hand. But she was at a bad angle, and finally she
had to let Kari's breasts go. She slithered down Kari's body, tonguing her
abs, and leaving a trail of pussy juice on the older sister's toned leg
before she sat up, the very top of her head brushing against the table.
Again she formed a duck-bill shape with her hand, and then pushed hard on
Kari's opening.

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

Kari's eyes opened wide and she groaned as she felt her cunt lips stretch to
accommodate Sam's hand. She was easily able to feel it as the last bit of
the hand popped in, and Sam was buried up to the wrist in her pussy. She
moaned aloud, reaching down and grasping one of her large, firm breasts,
lifting it to her mouth to suckle on it while Sam explored the depths of her
pussy. She could feel the fingers moving around, poking her in places she
could never have reached herself.

All too soon, she felt herself building towards a shattering orgasm.
"Sammm," she groaned, releasing her breast from her mouth, "I'm gonna cum,"
she gasped out. Sam gave her one last thrust for good measure, then pulled
her hand out as Kari screamed, her cum jetting out of her to cover Sam's
face and breasts. Kari continued to writhe and spasm long after her lungs
had exhausted themselves and her scream had come to an end. Sam planted her
mouth directly over Kari's pussy, and took as much juice in as she could,
swallowing  the salty-sweet liquid as quickly as she could manage. Still it
was too much. She slid up Kari's body, releasing a mouthful on her sister's
glorious breasts, then lay one her side, one leg draped over Kari's
well-defined stomach, and smiled at her sister, who gave a smile in return.

Kari leaned in and kissed Sam on the lips, tasting her own cum there, which
she licked off with her tongue, too worn out to do much else. "Sam?" she
asked when they had been lying like that under the table for at least five
minutes. "Why didn't we start this years ago?"

Sam sighed contentedly and nuzzled her face into Kari's slightly sticky
hair. "I think I would have freaked," she said quietly. "It wasn't until a
few months ago that I started thinking about you while I was bringing myself
off."

Kari nodded, breathing in and out, watching her breasts rise and fall in
front of her. "And I didn't really start lusting after you until after your
breasts really started to grow, again, a few months ago. When they went from
those cute little A cups to these D cups in almost no time." She laughed
nervously. "When you started having to buy new bras and swimsuits every two
weeks, I noticed."

Sam smiled and licked the side of her sister's face. "Yeah. That's slowed
down, but I don't think it's stopped. I'm probably gonna end up with the
same dimensions as you." She licked her sister's face again, tonguing the
ear lightly.

Kari turned her head to face her sister, catching the extended tongue in her
mouth and gently nibbling on it before letting it go. "You could end up
larger," she said. "My breasts weren't as big as yours when I was your age."
She forced herself into a sitting position, scooting herself out from under
the table. "Come on, let's get showers."

Sam scooted herself on her back out from under the table, not bothering to
sit up until she was free.  "Why bother?" she asked. "We'll just get dirty
again. We might as well shower when we're just about ready for bed." Kari
didn't respond, recognizing the truth of Sam's statement. "But what do we do
now?" Sam mused, almost to herself as she stood. Kari managed to get herself
upright on still shaky legs with some help from Sam. Who smacked her ass
playfully once she was standing. "Follow me," she said after a moment,
leading the way upstairs.

Kari followed her, her eyes glued on Sam's shapely legs and ass. "No
complaints here," she said, eliciting a giggle from Sam.


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

When she got to their parents room a few steps ahead of Kari, she found the
discarded strap-on, still wet with her own juices. It was a simple matter to
pull it on. Kari watched her do so with mild interest and intense lust
apparent in her eyes. Samantha turned around showing the ten inches of
rubber now attached to her thin frame. "What do you think?" she asked with a
thin smile. "Are you ready to get the shit fucked out of you?"

Kari's weariness from before seemed to instantly vanish. She didn't say
anything, just nodding and stepping towards her sister. Samantha didn't wait
for her sister to get in close to her, covering the remaining distance in
two steps and shoving the long rubber cock deep inside her sister while she
was still standing. Kari gasped in surprise, but the cock had slipped in
easily enough. Samantha stood on her tiptoes, getting it all up inside her
sister, deeper than even her hand had gone. She kissed Kari passionately on
the lips, an open mouth kiss that Kari returned with equal passion. The two
swayed around the room in a sort of imitation of a dance, Samantha's strapon
still buried deep inside Kari's pussy.

They finally stopped when Kari backed into a wall. Samantha gripped her
sister's upper arms, and began to do an imitation of the squats. Every time
she bent her legs about nine inches of the rubber dildo would slide out of
her sister's sopping pussy, and then she would straighten up and slam it
right back in. The four inches in her own end were doing a pretty good job
of stimulating her cunt, though she could tell that Kari would reach orgasm
well before she did.

That was fine, she decided as Kari gripped her shoulders and in consequence,
some of her dark brown hair. Samantha was relishing the rhythmic feel of her
breasts sliding up and down her sister's sweaty body, he nipples hardening,
and the brief pressure she felt as they mad contact with Kari's breasts.
>From what Samantha could tell, Kari's nipples were just as hard as her own.
She felt Kari's body begin to jerk, and heard the moans of her approaching
orgasm. She pulled out, and Kari tried to impale herself on the dildo, now
moaning in unfulfilled desire. She was hovering on the very edge of a very
strong orgasm, and Samantha was denying it to her.

She turned Kari around and pressed her against the wall, licking the nape of
her neck. "You're an anal virgin?" she asked quietly, continuing to lick her
sister's back. Kari nodded and Sam gave a silvery laugh. "Not for much
longer," she said, moving the very wet cockhead up and down between Kari's
thighs, particularly around her puckered hole. Kari was too far gone to
protest, and she couldn't reach her own pussy from the way her hands were
trapped against her body.

Finding the angle inconvenient, Samantha dragged her sister over to the bed,
and forced Kari to her knees, with her upper body on the bed, and her ass
protruding out over the side, her legs on the floor. Samantha grasped the
firm, tanned globes of Kari's ass and pulled them apart, revealing the
small, puckered hole. She placed the cockhead against it and pushed,
watching in amazement as the hole expanded to swallow the head of the dildo,
and she began to push the shaft in as well.

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

Kari's ass seemed to explode with pain, and she screamed loudly. Underneath
the pain though, she could feel the pleasure, and she knew that it was only
transitory. Once her ass had adjusted to the huge dildo, all that would be
left was the pleasure. At the moment though, she was in agony. She finally
felt Sam's hips touch her own, and Sam's hands began to lightly trace their
way down her side. Sam leaned in, her large breasts flattening against
Kari's back, and whispered in her ear. "I'll wait. Just tell me when you're
ready for it."

Sam's hands continued to play with Kari's sides, particularly focusing on
her hips and the outer edges of her ass. Meanwhile Sam's tongue traced it's
way along Kari's upper back, neck, and face. Finally, Kari felt the pain in
her ass begin to subside. After a few minutes, it had disappeared entirely.
Finally, she reached back and grasped what she could reach of Sam which
turned out to be her right arm. "I'm ready," she said.

Sam didn't need any more encouragement. She slid the strapon almost all the
way out, and rammed it in deep. Stars exploded in front of Kari's eyes. She
couldn't believe the sensations. It was like nothing she'd ever experienced
before. She gasped, moaned, her head rolled from side to side. "Fuck me!"
she yelled. "Fuck my ass Sam! Fuck it! Harder!" Sam's rhythm increased, and
Kari began to hunch her ass back, trying to increase the penetration as much
as possible.

Sam was sweating. Kari could feel it dripping off of her sister's breasts
and onto her back. Kari herself was sweating bullets as well, the smell of
sex and sweat mingling in the air. Kari could feel clearly every bump and
ridge on the toy as it slammed into her ass. She could feel her orgasm
building within her, and within a few moments her cries for Sam to fuck her
had descended into simple screams.

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

When Kari's orgasm began, Samantha cupped both her hands under the tap that
was her pussy. As the juices flowed, Sam splashed them over her face and
chest, then cupping her hands once more, drank the sweet nectar that was
flowing from her sister's spasming body. She pulled out, watching as her
sister's ass went from a gaping hole back to the tiny pucker it had been.
Then she flopped down onto the bed, exhausted, unsatisfied, her breasts
having.

Kari rolled over to come to rest next to her, her eyes shining. "That was
amazing, Sam," she said lustfully. After a moment, she frowned a little.
"But you haven't cummed yet, have you?" Samantha shook her head. Kari
smiled. "Well, I should change that," she said. She walked away from the
bed, towards the pile of toys on the ground. Samantha watched her tight ass
sway as she walked, then watched her as she bent over searching through the
toys. Finally she found what she was looking for. A string of anal beads
with a furry tail attached to it, and a large vibrator, probably about a
foot long, and thicker than the strapon.

"Get on your hands and knees," Kari said without preamble, and Samantha
obeyed before she really even thought about it. Kari walked over to her and
handed her the beads. "Suck on them," she said. "Get them nice and wet."
Samantha took the beads and began to suck on them with gusto. Kari spread
the cheeks of her ass and began to lick her small hole, lubricating it for
penetration. "Okay, give me the beads." Again Samantha just handed her the
beads without thinking about it.

Kari put them up to her hole and popped them in one at a time, each one
causing a mix of pain and pleasure for Samantha, until they were entirely
inside her. "Ooh," Kari said. "Stand up and look at yourself in the mirror."
Samantha stood up and walked over to the mirror. Her large breasts stood
proudly out, topped with her beautiful pink nipples, now hard as diamonds.
She followed her eyes down her athletic stomach to her pussy in between two
muscular thighs. She turned around, and saw the tail sticking out of her
ass, and she could suddenly feel the beads inside her.

Kari was looking at her with a large grin on her face, seated on the bed.
"Come here," she said. Samantha took a few steps across the room, feeling
the beads in her ass stimulating the walls, the tail brushing against the
back of her thighs as she went. By the time she reached the bed Kari had
stood up, and she pulled Samantha into a tight hug, and the two kissed
passionately, their tongues dancing around for a few minutes, groping and
feeling each other's bodies.

Kari grabbed Samantha's shoulders, spinning her around and pushing her down
onto the bed. Kari lay down atop her sister, and held up the huge vibrator,
and brushed it across Samantha's face, trailing it from her forehead to her
nose, down to run around her lips. Open up, Sam," she said. Samantha opened
her mouth as wide as she could and the vibrator slid inside.

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

Kari watched with amazement as the vibrator slid into Sam's mouth. The thing
was over a foot long, and only a few inches fit inside it, her lips were
stretched around it and the whole thing seemed like it could barely fit
inside. Sam was breathing intently thorough her nose, then without warning
she reached up and grabbed her sister's hand and pulled it down, pushing the
vibrator further into her mouth and down her throat. She was deep-throating
the vibrator!

Kari couldn't believe it. Though really, when she thought about it, this was
all unbelievable. Her incredibly sexy fifteen-year-old sister was lying
naked on their parent's bed, Kari lying on top of her, equally naked, the
two of them having had an incredible amount of sex in the past few days. Sam
had established a rhythm on the vibrator, and finally, Kari pulled it out.
Sam's breasts heaved greatly with her heavy breathing, and Kari wasn't about
to give her any respite.

With barely any preamble, Kari placed the head of the vibrator against Sam's
pussy, and pushed. Sam's cunt lips stretched wide to accommodate the
vibrator's immense girth, and then it began to slide inside her, inch by
inch, until finally, the entire foot-long length was deep within her. Sam's
eyes were rolling, sweat had pooled in every valley on her body, beaded on
every bit of her tanned skin, and she was gripping the covers tightly with
her fingers and panting. Then Kari switched the vibrator on. Sam froze,
absolutely motionless for a few seconds, she didn't even breathe, the only
sound the vibrator's muffled buzzing within her.

And then she let loose, a scream of pure, primal pleasure. She shook with
the power of her orgasm, droplets of sweat flying off of her. Juices flowed
out of her pussy around the immense vibrator, and one orgasm flowed into
another and another. Finally Kari pulled the vibrator out of her sister's
sopping pussy, and the orgasms died away. She sucked and licked the vibrator
clean, than looked at her younger sister. She had fallen completely asleep.

Kari smiled, setting the vibrator aside, then she moved up to rest against
her sister, wrapping her arms around the young girl who had become her
passionate lesbian lover. Nothing could come between them.

End Chapter 4....

I have run out of ideas for what the sisters can do together with only the
two of them. I am planning on introducing a new character in Chapter 5. At
the moment, my thoughts are centered on a girl named Kimberly, the younger
(how much younger, I am unsure) cousin of Sam and Kari, who will spend a
night or two at the house, and discover the sisters' secret. Any ideas or
suggestions along this line would be appreciated.
