Pulling the Strings: Chapter 4
Chapter 4: Sister's Turn
Little Katy was laying on her belly, gasping and panting while she played with her little immature twat, eagerly driving two fingers into her damp young passage. What's more her fingers didn't linger there very long, just enough to gather up what moisture they could, before trailing higher to rub at her already slick little pucker. Parting the ring to dig into her tight rear passage, making the girl gasp and squirm with delight.
Jack was surprised, he hadn't programmed his little sister specifically with anal in mind, but it seemed the show she got earlier affected her more than he thought. This certainly had promise though. It only took a thought to activate his sister's nanites and make them alter the nerves in her anal passage, increasing their sensitivity while also enhancing the elasticity of her virgin pucker in preparation.
Stepping into the room, Jack's once flagging cock rises once more. "Well now sister obviously someone enjoyed the show earlier." The sound of his voice causes Katy to practically shriek and whip around toward him, trying in vane to cover her girly bits.
Jack laughed warmly while for several moments little Katy simply gawked at her brothers huge cock, which throbbed hard before her eyes. Jack slowly moved closer, his huge cock bobbing with every step, while his little sister failed to tear her eyes away from his thick veiny shaft. He knew she wouldn't be able to help herself, and sure enough his little sister slowly reached out to grasp her big brother's cock.
She gasped at the feel of it, and blushed hotly in embarrassment, but still held onto that huge cock, stroking it slowly with one hand, then two, soft little fingers dancing along his fat pulsing veins in ways that made Jack groan with delight. Soon big glistening globs of precum were oozing from the tip of that towering spire.
Lowering his cock, Jack pointed the wet tip at his sister's mouth. Now she hesitated, but the smell of her brothers cock triggered something in her, a hunger she'd never felt before. Without thinking she leaned forward and gave the tip of that huge thing a quick lick. Her eyes practically rolled back into her skull as she sampled the taste of her brothers precum for the first time. Then she lunged forward, attacking the end of her brothers cock with a nearly ravenous hunger. Her lips latch onto to that big mushroom cap, and start sucking feverishly to draw forth more of her brothers delicious precum.
There was no hope of Katy actually fitting that fat helmet into her mouth, so she settled for suckling like a hungry kitten. Which still earned her all the precum she could drink, and swallow it she did, her throat visibly gulping down her brother's liquid lust. Katy's fingers quickly returned to her nethers, furiously frigging herself to one mewling orgasm after another. Her little immature pussy twitching with pleasure. Her snug pucker clenching repeatedly as well.
Slowly Jack drew his cock from his sister's eager lips, causing her to whimper and look adorably dejected. She pouts up at her brother who simply smiles down at her and playfully pushes her onto her back. The teenage boy licks his lips and slides his shaft down his sister's body, making the girl gasp as he grazes his hot cock over her puffy little nipples, and sloowly grinds his fat shaft between her thighs.
Katy squirms but doesn't resist. Quite the contrary, she actively arches her back and presses up against her brothers girthy shaft, desperately trying to grind her slick young cunt against her brother's huge poll. Just the process of sliding that cock down between Katy's thighs caused her to shiver and shudder once more.
"Mmm, I didn't expect you to be -this- eager sis. You really do take after mom." Jack teases, while his sister pouts again, but it was short lived as another gasp escapes her lips as that big mushroom cap presses against her little immature muffin. She whines in want, and spreads her legs wider, lifting her hips to try and press against her brothers girth. Even if she knew it would never fit. There was a desperate need burning in her loins, and only her brothers cock could sate it.
Jack knew otherwise, he could and would fit, he'd prepared his sister's body for this moment a long time ago. Leaning down he pinned his sister's shoulders to the bed, not unlike his mother did to him not too long ago, and started to push. Slowly but surely those snug little lips started to part, yawning wider by the moment to embrace his cock. Katy gasped and writhed, scared but wanty. Looking down her body the young girl could only watch in amazement as her preteen pussy slowly spread around her brothers cock, gradually letting him in deeper, until his glans POPPED inside.
Katy shrieked, and clawed at the bed as her whole body tensed up at once, wincing in discomfort from the intense stretching but that was completely overshadowed by the girls first -real- orgasm. She whined and bucked, thrashing under her brother, while her far too young pussy pulsed and sucked at the huge glans stuffing her passage. She was only given a few more moments to recover before Jack started inching that huge cock deeper. She was still panting when the first few inches of fat teenager cock sank into her still twitching cunny. IT made her both wince and groan as she was stuffed deeper, and deeper still. Katy arched and whined, it was too much, all that cock she shouldn't be able to hold that much, but more and more of her brothers meat pressed endlessly into her.
The teenage boy growled in lust as he watched his huge cock delve deeper into his little sister's cunt. He was determined to hilt that entire beast home before his balls inevitably blew, it was not easy though, his sister's preteen pussy was so fucking tight that he had to fight for every inch he forced into her. The sheer amount of wet friction was almost overwhelming, for both of them. It was Katy who gave out first however, as her brother's cock forced its way into her womb she gave another loud shriek and sized up, every muscle in her body locking while her immature cunt clamped down like a vice, locking Jack's dick in place. The young girl simply wasn't ready for an orgasm that powerful and moments later slumped onto the bed, out like a light.
Jack sighed down at his unconscious sister. He was still hard as a rock, and so damn close to cumming that he couldn't just stop there. At least his mother drained his balls several times over before she passed out. Well he wasn't about to stop now. Slowly he pulled his massive meat free, slowly and carefully mostly so he didn't pop before he was ready. Katy simply twitched and groaned as her pussy was left woefully empty, causing her to whimper in her sleep.
She was easy to roll over at least, allowing Jack to rub his fat dick against his little sister's smooth silky ass. Licking his lips, he parted those cheeks to slide his tip up and down her cleft, smearing his precum over the girls inviting little asshole. This made Katy shiver, while the nanites forced her awake with a jolt, just as Jack was starting to spread her little star open around his tip.
"B.. brother!" she gasped, arching, and unconsciously pushing back against his cock as her pucker was spread, slowly, gently, but inevitably. Biting her lower lips she rested her chest and cheek onto the bed and lifted her little rear higher, pressing back against her brothers huge helmet, which was already spreading her preteen pucker wider than should be possible. "Mmm.. brother... please?.. fuck me?" she asked in a nervous, tentative voice, copying some of the things she heard her mother say, in a much more timid tone.
Jack was all too happy to oblige. Pressing forward more firmly he crammed his cockhead into his sister's ass, relishing another wet pop as her snug ring clenched just past his crown. This time though he didn't give her a chance to relax, and started forcing more of his fat meat into his baby sister's pliable asshole.
Katy clutched her tummy with one hand, marveling at the bulge she could feel sliding up her tummy. Her pussy fluttered, her juices coming in wet spurts as she shuddered through orgasm after orgasm. They weren't as intense as the one that put her out, but they just kept cumming one after another, her tummy muscles constantly clenching and rolling while soft blissful whines and moans left her lips.
"Mmmm, yesss." Jack hissed as he hilted his huge cock deep in his sister snug asshole. This was just fucking perfect. Her pussy was tight, a bit too much so, and too sensitive for her to handle. Katy's asshole was just right though, his last minute modifications let her handle his cock up her ass nicely, keeping a firm grip but not keeping him from moving. He was just about to start fucking his sister in earnest when he heard a noise from the doorway. Looking over he gasped. Shit he forgot to reactivate communication between his and his mother's nanites.
There Elizabeth stood, posed in the doorway, one elbow raised and resting on the frame. "Well fuck boy, you just couldn't wait could yah? You just got done fucking me into a stupor and you're already plowing your sister." the large luscious woman stepped into the room and ran a hand across her son's rear. "Mmm, if it weren't so fucking hot I'd be furious."
Just minutes before Lizzy had woken from her sex induced coma to the sound of her daughter's orgasmic shrieks from down the hall.. Worried about her daughter she quickly made her way to the young girls room and looked inside. Just in time to see her son hilt his huge cock inside her daughter's far too young pussy.. all of it.. and somehow her daughter not only took it but clearly came her little brains out. That turned on Lizzy so much she let out a lusty growl that was just quiet enough to not be heard over the young girls orgasmic screams. After that Lizzy quickly made her way back to her room to gather up a few things.
Now there Jack was, buried balls deep in his little sister's tight ass, with something big and phallic shaped resting across his rump. His mother had put on a huge strap on, a big blue plastic cock that looked to be nearly as big as his own... this was a very unexpected turn of events. Jack knew what was about to happen, and while he wasn't sure he wanted it, at the same time he was mildly curious. So he made a few quick modifications to his, ah, back passage. Similar to the one's he made to his sister's.
Just in time too since Elizabeth was already smearing lube over that giant blue plastic cock. "Well you've had your fun boy, but now momma's gonna show you how its done." The large matronly amazon practically rumbles while she wedges that big blue plastic cock between her son's cheeks to press it against his virgin asshole. She barely spread the lube around that tight pucker before shoving forward hard, to cram that big plastic cockhead into her son's rump.
Jack grunted, thankful for the quick modifications he made to himself, otherwise the sudden penetration would likely have been agonizing, and harmful to his health. As it was it was merely somewhat uncomfortable. However, Jack had made another miscalculation. His enlarged reproductive system had an unforeseen result, an equally enlarged prostate, which made a big target for his mother's strapon, and an unexpected result. He groaned, not in pain or discomfort, but from intense unexpected pleasure. His cock jerks inside his sister, who was still moaning through her repeated anal orgasms, and pumps an ungodly amount of precum into the girl.
"Mm, there you go boy, like momma's big dick don't you?" she teases, swatting her son's hips playfully before she grips firmly and pulls back, keeping her son's rump pressed against her groin but pulling Jack's cock out of his sister's ass. Then thrusts forward, forcing her son to fuck her daughter's ass good and hard, while that big blue cock hammers her boy's bloated prostate. Both of her children could only hold on for the ride as mothers powerful hips drove both cocks, real and fake, into their respective holsters,
The teenage boy could barely hold on, he'd never experienced anything like this, and knew this event would alter his plans, at least somewhat. Having a hugely over sized prostate it seemed, had certain advantages, and he intended to enjoying them. As it was, a few more blows to his gland from his mother's giant blue strap-on had the boy arching, and groaning as he started pumping a huge load of cum into his sister's delectably snug little asshole.
Poor Katelyn was mewling and squirming again under the hard pounding, pressing her preteen ass up against her brother's slamming hips, barely aware of her mother's presence at all, her whole world was the huge throbbing cock slamming past her preteen pucker, and pumping all that thick cum into her belly, making it swell, and Jack doubted he'd be going soft anytime soon with all that pressure against his prostate.
So it went for the rest of the day, with all inhibitions smashed, the family spent hours upon hours exploring all manner of carnal pleasures together. Only stopping long enough to take care of physical necessities like food, before throwing themselves back into another round of raucous incestuous fucking. Its a good thing it was Saturday.
By nightfall they were all completely spent and exhausted, beyond even their nanite's ability to keep them going. They were all passed out, sprawled in a pile atop Elizabeth's king sized bed. Jack's mind kept going though, pondering ideas and plans. It was time to move to the next step of his plan, but he was still considering just how to go about it. He needed his mother to be willing to accept the transformation he had in mind for her, otherwise the rest of his plan wouldn't work. He could easily force her to eagerly accept it but that felt wrong. The modifications he made to his mother's mind were largely for her own good, this was different though. He was just about to drift off to sleep when an idea hit him. One he implemented even while his body drifted off into slumber.
