Sibling Rivalry 

By Adiemus Bacchante 


Twelve hundred kilometres in minivan isn't fun at the best of times. 
Especially not for children, so when Tom and Margaret set off across 
the country, they shouldn't have been surprised when Steve and Amy 
started acting up in the back. The two siblings weren't especially 
close in age, Steve being a tall, muscular sixteen year old and little 
Amy having just turned twelve a week after school let out for the 
summer.  

As the family drove past farmer's fields and seemingly endless 
countryside, the two siblings became bored. It started out as simply 
poking one another in the arm, and moved on to Steve making faces at 
Amy and calling her ugly under his breath. The girl heard of course and 
started yelling for her parents. Doing their best to placate their 
bored children, Tom and Margaret tried to settle them with promises of 
being there soon and stopping for ice cream at the little town of 
Ravensmoor along the way. Somehow, this wasn't enough to alleviate the 
boredom, however. 

For another hour the two exchanged angry words, dirty looks, and the 
occasion light swat against each other's arms. Once or twice, Steve 
even gave one of little Amy's blond pigtails a sharp yank, causing 
their mother to yell angrily at them both. The trip seemed to get 
longer and longer as time went on. But then, they past the first sign 
advertising the Black Thorn Restaurant in the town of Ravensmoor. That 
was when it happened. 

With a heavy silence hanging over the van, Steve glanced askance at his 
little sister, the girl having folded her arms across her chest, 
angrily staring forward. Without a word, he unbuckled his seatbelt and 
turned towards her, his lips forming a malicious grin.

Turning her head away, Amy harrumphed and refused to look at Steve, 
even when she felt and heard him undo her seatbelt. In the front, their 
parent's did their best to ignore the two, both of them fed up by that 
point.

Steve, however, didn't care at that point. Inhaling deeply, his large 
hands suddenly grabbed his little sister by the shoulders, causing the 
girl to turn to him with a shocked look, her scathing comment catching 
in her throat as she saw the look in his eyes.

Wasting little time, the young man pulled Amy forward, one hand 
shifting to grab a dangling pigtail as the other slipped down to undo 
his fly. The van hit a bump at that moment, disguising the sound of a 
descending zipper, Amy's gasp as her brother pulled out his thick, 
throbbing cock the only sound their parent's heard. 

"S-Steve-!" Amy cried out, suddenly realizing what was happening as her 
brother pulled the girl's hair downwards, his other hand causing his 
cock to smear pre-cum across the child's lips, "S- Stop it!"

"Both of you fucking stop it!" their father yelled from the front seat, 
not bothering to look back, "Or I'm turning this van around!"

Steve didn't seem to notice or care about the threat. Yanking his 
sister's hair, the girl wincing, he inhaled sharply as his thick cock 
shaft slid into the little blonde's mouth. 

Amy's eyes went wide, the girl gasping in shock, her tongue yanking 
back, curling to escape the strange flavour of her own brother's shaft 
in her mouth. Unable to protest except for a muffled exclamation of 
sudden panic, the girl tried to pull away but her brother was 
relentless, pushing the child down on his cock until the head of it 
pressed against the back of Amy's throat.

"That's better," their father grumbled from the front, ignoring the 
muffled gurgling as Steve inhaled sharply, the sensation so intense 
that it caused his cock to throb.

Just then, though, Amy's fist smacked into the back of her father's 
seat. "HEY!" the man roared, the van veering dangerously as he turned 
around in his seat, the man's anger quickly turning to astonishment as 
he saw that Steve was now forcefully yanking little Amy's head up and 
down by the pigtails.

Staring in disbelief, the sight of his daughter's mouth stretched wide 
around his own son's shaft as tears fell from her wide blue eyes etched 
forever in his mind, the man could only stammer and stutter as the 
scene seemed to go by in slow motion.

"Tom!" Margaret screamed, grabbing the wheel and pulling the van back 
into their lane, a passing transport truck blaring its horn at them, 
the woman screaming at her husband angrily, not hearing the renewed 
muffled screams from the back as Amy's fist hit the back of the seat 
several times before Steve grabbed both the girl's wrists in his large 
hand.

"You could have fucking killed us!" the woman shouted, exasperatedly 
throwing her arms in the air and shaking her head, refusing to look 
into the back seat as her husband sat staring numbly forward, unable to 
accept what he'd seen, "Honestly! I hope you're all happy now!"

Steve was certainly happy. He grinned as he caught his father's gaze in 
the rear view mirror, the young man happily forcing his little sisters 
head up and down, her saliva drooling out around his shaft, coating his 
balls. 

As his father glanced back at the road, his face pale, ashen, Steve 
leaned forward, using his weight to keep his sister's head down, 
causing the child to gag as his cockhead pierced her throat, and 
reached under the front seat. Pulling out the extension cord the family 
kept there for camping, the young man quickly tied his now struggling 
sister's arms behind her back. 

Pulling her head up at last, Steve grinned as his sister gagged and 
coughed and cried as she tried to catch her breath, their parents both 
ignoring them for the moment. Chuckling softly, Steve ignored the look 
of horrified betrayal on his sibling's face, the girl whimpering and 
scared, her body shaking all over.

Instead, the young man pushed her over a bit and stood awkwardly, 
shuffling to get to the other side of her. "Sit the fuck down, both of 
you!" their mother demanded without looking back, their father letting 
out a soft whimper, the man biting his bottom lip as he watched in the 
mirror.

"Yes, mother," Steve said coolly, holding Amy's wrists again as the 
girl looked back at him, her lips working, unable to speak as her small 
throat contracted.

Wasting no time, Steve threw up his sister's knee-length skirt and 
ripped down her panties. "N-Nooo!" Amy finally cried, the girl letting 
out a piercing, screaming shriek as her brother then grabbed his cock 
and lined it up against her young, virgin pussy, "Mommy! Daddy! 
Heeeelp!"

"What the fuck is it now-?!" Margaret began, the angry woman turning 
around just in time to see her daughter on her stomach, wrists tied 
behind her back, lying across the back seat as her brother pulled up 
her hips and pushed his cock against her tight, hairless, twelve-year-
old pussy.

The woman stared in disbelieving horror as her daughter screamed in 
pain, her son's cock shaft pushing hard, spreading the little girl's 
young folds, piercing her pussy, violating Amy's body with several 
quick, hard thrusts that made the young man grunt as he gritted his 
teeth and grinned at his handiwork.

"N-No." Margaret stammered, unable to move, paralysed by what she saw. 
As Amy's head turned towards her mother, the girl's expression 
pleading, Steve pulled his sister's hips higher, her firm little round 
ass wiggling and bare as the girl-child let out another sobbing scream, 
marking the moment when her own big brother robbed her of her 
childhood.

Gasping as he broke his little sister's hymen, Steve grabbed hold of 
Amy's ass cheek and one of her pigtails. Squeezing and pulling, the 
young man thrust harder, bucking, jerking his hips forward, shoving 
every last inch painfully into his sister's tiny, dry, virgin pussy.

"Fuck yeah-!" Steve grunted, the little blond sobbing and crying, 
grabbing hold of the seat for support as she tossed her head back and 
screamed, feeling the head of her brother's cock press roughly against 
her cervix.

"Steve-! Nooo!" the child pleaded, but the young man didn't care. 
Thrusting back and forth now, Steve glanced at his mother and grinned.

"Dad ain't got the balls to do this!" he laughed, slapping his sister's 
small ass, causing the girl to cry out in humiliated pain, "So I'm 
doin' it for him!"

Shaking her head in disbelief, Margaret turned to her husband. "P-
Please, Tom," the woman pleaded, the sounds of flesh slapping, her 
little girl sobbing and her son grunting filling the otherwise quiet 
van, "Please tell me this is all just a bad dream!"

But it wasn't. Throwing his head back, Steve's thrusts quickened, the 
young man's cock ramming and shoving against his sister's cervix, 
hammering the entrance to her young womb like a jack hammer as his 
shaft stretched and pulled the tight inner muscles, stretching them 
brutally, his full, heavy balls slapping against the child's pale, 
slender thighs.

"M-Mommy! Please-!" Amy pleaded, tears forming in her mother's eyes as 
the woman gripped her husband's arm, the man accelerating, ignoring 
them all as best he could, his son's words stingingly true, "M-Make 
them stop! He- He's going to. to. You know! Amy-! She- fuck Tom, she's 
just started having her period! He could get his own sister pregnant!"

Steve laughed at this, the young man fucking his twelve-year-old sister 
harder now, his breathing quickening as his cock seemed to throb and 
expand, stretching his sister's pussy wider. "You- You hear, that?" he 
grunted with a grin, yanking Amy's hair roughly, "Mom say's you can get 
pregnant! Good fucking timing, sis!" 

Laughing, Steve winced as Amy screamed again, the girl's face pressed 
up against the window as she sought escape from the merciless pounding 
cock, her big brother's shaft pushing harder, forcing her cervix to 
buckle painfully, spreading open the girl's last defence before her 
young, fertile womb.

"I- I'm gonna fill you with fucking cum!" Steve promised, his shaft 
squeezed hard now by the tight ring, his brow wet from exertion, his 
sister now banging her little fist on the window as passing motorists 
stared in disbelief.

"No, Steve! No! No! No!" the little girl cried, her tears wetting the 
window as she rattled the door handle, the child safety lock keeping it 
closed, "S-Stop it! It- It hurts! You're hurting meeee!"

Steve didn't care, though. As his cockhead finally pierced his little 
sister's womb, he gave a loud grunting cry of victorious ecstasy. His 
hot, potent seed gushing into his sister, creating new life within the 
little girl. The young man's whole body shook hard, loving the 
sensation of directly inseminating his own sister, and on her first 
time to on top of it.

"Nooo!" Amy screamed, knowing instinctively what was happening, 
imagining the cheesy animated sequences in sex ed of the thousands of 
tiny sperm cells surrounding her little ovums, each of them piercing 
the membrane before dropping their cargo of genetic material. And with 
his cock firmly wedged in her very womb, there was nowhere for the eggs 
to hide. She was being knocked up by her own brother, and there was 
nothing Amy could do about it.

Bowing her head, Amy closed her eyes tightly and sobbed, gritting her 
teeth as Steve gave her several hard thrusts, emptying his balls 
completely before slowly pulling out. Chuckling to himself, the young 
man paused as his cockhead remained lodged inside his little sister for 
a moment. Glancing in the rear view mirror, he grinned at his parents, 
knowing there was nothing they could do about it. Or would for that 
matter.

Pulling out with a loud pop, Amy's still tight pussy squeezing closed 
with only the smallest trickle of semen escaping, Steve slapped his 
sister's ass with a laugh. "Wow, what a great fuck!" the teenager 
chided, pulling up his pants before sitting back down and doing up his 
seat belt, the young man grinning at the horrified expression he could 
see in his father's eyes in the rear view mirror. 

"A-Amy," their father managed, their mother beside him shaking 
uncontrollably, sobbing almost as much as the little girl, "P-Put your 
seat belt on, we don't want to get p-pulled over."

Margaret stared over at Tom, horror and betrayal crossing her face as 
the man gripped the steering wheal tighter, no longer able to meet his 
son's smug expression in the mirror.

"Yeah, Amy!" Steve laughed, slapping the child's ass again, causing her 
to let out another cry as she fell in a heap and sobbed, "Put your 
fucking seatbelt on! We don't wanna get pulled over!"

And so the family drove on in silence for several minutes, going 
straight past the Ravensmoor off-ramp until suddenly Steve's eyes 
widened. 

"What the fuck?!" he suddenly exclaimed, staring at his crying, shaking 
sister, a trickle of cum leaking from her exposed pussy and feeling the 
raw, used feeling of his manhood. Glancing at his parents in horror, 
the young man leaned between the seats.

"Wha- What'd I miss?!" he croaked, terrified, shaking all over. But his 
parents ignored him. The family continuing on its way, doing the best 
it could to pretend the whole incident never happened. At least for the 
first few months, at any rate.
