***** Sweet Temptation *****
Although the cactus juice tasted funny, Toph had to admit that the sweet
smelling fluid was very thirst quenching. Drinking greedily from one of the
cactus plants that Sokka had bisected, she sighed in pleasure as her parched
throat got some relief.
Stranded here in the Si Wong Desert after Appa had been stolen by Sandbenders
and Aang had left in a huff to find him, the only available fluids were either
the cactus juice or Katara’s bad tasting waterbending water. And although the
older girl had cautioned her against drinking the juice, Toph was far too
thirsty to care. Besides, Sokka, who was gorging himself on the juice, had so
far suffered no ill effects. Toph reasoned that if they were to make it all the
way to Ba Sing Se, to warn of the coming solar eclipse, they would need this
bit of hydration.
As she finished draining the fruit of its juice, she heard Sokka behind her
complaining: “It’s just too hot under these clothes.” She thought there was
something strange about his voice and as she heard the rustle of clothes she
became concerned. Hearing Katara gasping and then starting to splutter, Toph
turned around, alarmed.
Unbeknownst to the Earthbender, the cactus juice had finally managed to reach
her young mind. Exerting its effect, the juice caused a wave of hazy pleasure
to flood her mind, drowning out her concerns. Working along two different
paths, the juice both removed her inhibitions and fuelled her arousal. It was
the plant’s defence mechanism, a way to ensure that it could survive in a
desert where every living thing thirsted after its fluid contents. Any
sufficiently big predator would soon find itself too occupied by its mating
needs to do anymore damage to the cactus.
As her judgement unravelled due to the juice’s effect, she became aware of heat
building up in her body, especially deep in her sex. Soon the heat was so
intense that her only desire was to get out of her clothes.
“Too hot... Need fresh air...” she found herself agreeing with Sokka’s earlier
statement.
Desperate for relief from the intense heat, she wasted no time in removing her
black belt, yellow tunic, green shirt and pants, as well as her light green
undergarments. Her small breast buds with their tiny pink nipples, her muscular
limbs, flat stomach, tight ass and vulva with its sparse almost invisible small
curls were soon bathed in the intense desert sunlight. Spreading her arms and
thighs open, she enjoyed the desert wind blowing across her body.
Dimly she heard Katara protesting: “Toph, you can’t just undress! What is wrong
with you two?!” The juice’s effect on her mind ensured that she paid the
Waterbender no attention.
Despite being free of her encumbering clothes, the heat inside of the dark
haired girl’s body was still growing due to the juice’s effect. Her clit
engorged with blood, her young sex lubricated itself and her nipples hardened
to peaks as the unnatural lust took control of her. A puppet to the juice, her
left hand’s fingers started to pinch and twist her aching nipples while her
right hand trailed down her tight abdomen, her middle finger starting to rub
her throbbing clit.
While she couldn’t see with her juice induced-dilated sea foam green eyes, her
‘seismic sense’ allowed her to realise that Sokka was busy stroking his aroused
manhood. This knowledge caused her arousal to spike even further, her finger
becoming wet with sticky fluid as her sex hungered for relief.
Katara was still protesting, but the haze of pleasure in Toph’s mind made her
unable to make out any of the older girl’s words. She felt Sokka approaching
and offered no resistance as he picked her up with his hands wedged into her
armpits, her own hands moving away from her erogenous zones. Wrapping her
strong short legs around his waist, she felt his hardened manhood brushing
against her arousal-slickened nether lips. Sokka’s lips crashed down onto hers,
the flood of desire in her mind making her open her mouth and start to duel
against his tongue with her own.
Wrapping her arms around his neck in order to keep her lips against his, she
enabled Sokka to start kneading and squeezing her tight ass with his hands. As
another wave of desire burned inside of her, she started to rub her inflamed
clit and soaked petals against his fully aroused penis. Dimly through the haze
of pleasure she sensed that Katara was stomping around in agitation, but as
Sokka’s cock bumped against her clit and her stiff nipples rubbed against his
chest, she was lost to her lust.
The hot sand against her pale smooth back was no match for the heat inside of
her as Sokka moved them to a vertical position. Loosening her hold on his body,
she opened herself as wide as she could, allowing Sokka the room to start
rubbing his dripping wet purple cock head against her inflamed nether lips.
Driven by the juice, the teenage boy slammed his length into her vagina with
enough force to tear completely through her thin hymen. She gasped in a mixture
of pain and pleasure as her tight cunt’s wet walls were forced open by his
invading penis.
Wasting no effort on trying to be gentle, Sokka drove his hips against hers,
filling her tight sex completely with each stroke. Due to the juice’s effect,
they were literally fucking like animals in heat. Sokka moaned loudly as her
vice-like cunt wall constricted around his aching cock, enfolding his length in
moist heat. Toph was reduced to gasps of pleasure as the boy’s stiff penis
rubbed along her throbbing clit and started to hammer against her cervix.
Heat and pleasure radiated out of their groins, their nerves burning with
passion as they copulated on the hot sand. Streams of sweat trailed down their
bodies as they smashed their pelvises against each other’s. Finally it was too
much as their nervous systems were overloaded with pleasure. Sokka buried
himself to the hilt inside of her tight channel, stream after stream of his
seed flowing into her young womb through her battered cervix. As he attempted
to fertilize her eggs with a grunt, the new warmth flooding into her caused her
to tip over into her own orgasm. With a wordless cry, she locked her legs
around him, trapping him inside of her as she rode the wave of ecstasy that
tore through her body.
*
Katara had tried her best to not be a voyeur to her brother and her friend’s
raw fucking, but even if she closed her eyes and plugged her ears, she could
still smell their passion. She knew that she should have stopped them much
earlier, but the unrelenting heat had left her too tried to fight. And as her
own nipples grew stiff and her clit started to throb with need in response to
the spectacle, she couldn’t resist anymore.
With wide blue eyes she watched her brother’s darker manhood filling her
friend’s pale sex relentlessly, her own hand busy beneath her undergarment
stroking her nub as she couldn’t stop from moaning in pleasure.
Soon the copulating duo had reached their orgasmic finish, but Katara was left
unsatisfied. Dehydrated by the sun, assaulted by the raw eroticism that she had
witnessed and left with a throbbing clit, Katara’s good reason wavered as she
looked at one of the cactus fruits that still lay untouched.
The temptation was powerful as she licked her lips...

***** Taboo *****
With arousal still burning in her blood and her throbbing clit still in need of
relief, Katara walked towards her friend and her brother. They were lying next
to each other, their sweat slicked naked bodies glinting in the harsh sunlight.
Blushing, the black haired Waterbender tried to keep her blue eyes from looking
at Sokka’s slimy flaccid dusky cock or the pearly semen that seeped out of
Toph’s pale bare sex. Instead she tried to focus on their faces and their
chests. Their eyes were closed, but they were panting from exertion, their
chests drawing rapid breaths. Of course, looking at either her brother’s
muscled chest or Toph’s barely formed breasts made her clit pulse with desire.
She knew that they needed a drink urgently and that the small amount of water
that remained in her water skin wouldn’t be adequate. The only other fluid that
remained was the cactus juice, but she feared that the juice would do even more
harm to them. There was another option, but she would save that for truly
desperate times.
With little other choice, she used the fluid movements of her arms to bend the
cactus juice that remained in the opened fruits into the panting couple’s
mouths. She watched in relief as they drank, causing their breathing to calm
down and their panting to stop, but she was terrified at seeing just how
powerful the juice was. Not only did it seem to rehydrate almost instantly, but
it had also caused Sokka and Toph to completely lose their reason.
She had hoped that they would be too tired or that the effect of the juice
would have dissipated, but to her dismay the couple awoke and continued with
their shameless performance. With massively dilated pupils, Toph climbed on top
of Sokka and wrapped her lips around his slimy penis while his tongue got to
work on her cunt. Caught between wanting to stop the debauchery and wanting to
finger herself to oblivion, Katara moved around the intoxicated couple on
unsteady feet.
While she may have had many disagreements with Toph, seeing how raw the girl’s
sex looked from the savage fucking earlier and knowing that she was going to be
responsible for the girl getting fucked like that again, Katara was filled with
guilt. Even if she had given them the juice in order to save their lives, she
was the cause of everything that was about to happen.
This feeling of guilt, combined with the unrelenting heat of the sun and the
incessant aching of her clit had a toxic effect on her reason. In a daze,
wanting to protect Toph, she started to undress, hoping to keep Sokka’s focus
on her body. The removal of her light blue tunic and her sarashi left her firm
orange sized breasts with their dark brown hard nipples and her flat abdomen
exposed. Lifting her legs one at a time, she removed her boots. Pain radiated
out from her bare feet as the warm sand burned them, but she accepted the pain,
quickly divesting herself of her fur trimmed dark blue leggings and her
undergarment. Naked except for her necklace, with her full hips, tight shapely
ass and her lightly furred sex bared to the desert air, she walked over towards
where her friend was sucking Sokka’s cock.
Kneeling next to her friend’s head, basking in the heat that punished her knees
and legs, she gently pushed Toph into a sitting position on top of Sokka’s
tongue. Taking the girl’s place, she wrapped her lips around her brother’s cock
and started to stimulate it with her tongue while her right hand stroked his
hardening length and her left hand fondled his hairy full scrotum.
The taboo of sucking her own brother’s cock made her clit pulse with even more
urgency, while her friend’s now audible moans sent her pulse racing. Katara
blushed as she felt her thighs get wet from her arousal. Licking over his
fraenulum and into his piss slit, she soon had her brother as hard as he was
going to get.
Toph’s moans turned into gasps and finally she was locked in a wordless cry
with Katara watching out of the corner of her eyes as the Earthbender orgasmed.
Intensifying her efforts, Katara sucked hard on Sokka’s penis while she fondled
his testicles. Focused on her task, she hadn’t noticed Toph dismounting from
Sokka’s face and moving into position behind Katara’s tight ass, parting the
smooth cheeks with her hands. As much as she could with her mouth stuffed with
her brother’s prick, Katara moaned in both shock and desire as her friend’s
tongue started lapping at her drenched pussy and her aching clit.
The combination of the taboo touch of another girl’s tongue to her sex and the
burning arousal in her blood made Katara climax with little effort. In turn,
she sucked ever harder on Sokka’s manhood and was rewarded with a flood of
incestuous sperm down her throat as he grunted in pleasure. Caught in the storm
that was her orgasm, with lightning dancing up and down her nerves, she could
do little else but consume her brother’s spunk.
As Toph’s tongue continued licking over her coral pink sex, flicking against
her inflamed clit and even rimming the darker brown of her anus, Katara was
reduced to resting on her hands and knees, moaning raggedly as some of her
brother’s seed spilled from her lips. Despite her mind being flooded with
immense pleasure, she was able to turn her head and watch as her brother made
his way towards Toph’s unguarded twat.
Even with her orgasm dazed mind she recognised that this would render her
efforts so far all for naught. Moving with agility born from desperation, and
no small amount of lust, she leapt to her feet and managed to wedge herself
into position between her brother and Toph. The Earthbender’s protests at her
breeding instinct being denied were silenced as Katara’s tongue started to
dance over the girl’s flooded cunt. Sokka, obeying the juice’s directive to
breed, didn’t react to the abrupt change in partners.
Rubbing his wilted cock against his sister’s wet hot nether lips; he used his
hands to knead her firm buttocks. The taboo nature of what she was doing -
licking another girl’s snatch whilst practically begging her own brother to
fill her womb with his seed - almost made Katara orgasm again. Lost in the
pleasure, she went for broke and started to lick Toph’s dark pink anus whilst
filling the girl’s tight cunt with a pumping finger.
Driven by the desire that the juice instilled in him, Sokka was soon ready for
action again. With no subtlety whatsoever, he grasped his sister’s hips and
started to force his fully erect cock in between her wet lips. Katara buried
her face in her friend’s pussy, trying to drown out the cry of pain as her
brother took her virginity with a savage thrust of his hips. As tears gathered
in her eyes, she continued to stimulate Toph’s asshole with a finger whilst her
mouth was busy stimulating the girl’s sex.
Sokka was fucking her as hard as he could, her hips shaking with each impact as
he repeatedly filled her tight cunt, forcing her wet soaked walls apart as he
strove to fill her unprotected womb. The pain had managed to clear her mind
enough that she recognised that Sokka filling her with his seed would be a very
bad idea due to her current state of fertility. She knew that she would have to
get him to dismount sooner than later, but as his hips continued to smash
against her own his cock scraped along her clit, bringing pleasure to their
savage copulation.
Entranced by the sight of her winking darkest orifice, Sokka’s lust consumed
mind was driven to fill her ass with a finger. Katara’s moans became ever
louder as she was thoroughly fucked and her ass was filled with a thrusting
finger; the vibrations transmitted from her mouth to Toph’s cunt soon causing
the younger girl to be swamped by another orgasm. The orgasm caused Katara’s
face to be drenched in her friend’s fluids, which only made her moan ever
louder, prolonging the stimulation to Toph’s pussy and thereby her climax.
Meanwhile Sokka was rapidly approaching his own orgasm, his moans turning into
grunts as he sought release. His copulation with his sister was causing both of
their dark skinned bodies to become slippery with sweat, their bodies smacking
together wetly as copious arousal fluids ran down their thighs. With his penis
encased in his sister’s tight drenched deflowered cunt, Sokka’s nerves burned
with pleasure. Katara was little better, the incessant filling of her defiled
quim and the smashing of his cock against her clit had her nerves alight with
fire.
Her reason was so drowned in pleasure that she did nothing when with a furious
grunt, Sokka buried himself to the hilt inside of her, his cock jerking again
and again as his incestuous sperm flooded her womb. As she felt the warmth
flowing into her, as she felt herself get pregnant with her brother’s child –
the ultimate taboo – she screamed in orgasm as the forbidden pleasure
completely consumed her. Drowning in pleasure and warmth, she slid into
unconsciousness, all of her worries gone...
