Genestealers

(Hi, author here! Some quick notes before we kick off the fourth chapter of this series.

First, all characters are 18 and above wherever applicable. This series contains elements of futa and gay sex, incest, and several others. If that's not your thing, I totally understand - there are many, many stories here, some which may cater to your tastes better.

Second, on a personal note, I would like to dedicate this chapter to Mise. Again.

Lastly, thank you for the feedback - it's most welcome! Been a while, eh?)

In 1999, the fastest plane in the world was finally mothballed after years of faithful service. Built at an enormous cost for equally enormous aims, the SR-71 was the undefeated man-made ruler of heavenly speed.

But its time had come and gone at last. The government, forced by financial circumstance, decided to put their creations away to slumber in boneyards till they were needed again.

And so it came to pass that twenty of these magnificent aircraft were brought to the dry, hard-packed lands of Tucson, Arizona. A small crew made sure that every bolt, screw and panel was accounted for, and as day turned to night, they finished their tasks with mechanical precision. One day, they thought to each other, these planes might be wanted once more to serve the United States in a new role. Of course, none present actually looked forward to a day like that, but no one spoke of such seemingly unpatriotic thoughts.

What they didn't know then was that a week later, a group of soldiers - bearing papers with TOP SECRET emblazoned prominently on them - would take some of these planes with little protest from the boneyard's caretakers. None of the people present could accurately remember those who had carted the things away. The memory was vague in their minds, at best. The thought that they had been stolen never crossed their minds, and a strange apathy seemed to occur whenever the topic was brought up.

As for the jets, they had simply seemed to have vanished off the face of the earth. Until now.

It was a nail-bitingly bumpy ride from the offices of Project Scarlet Aurora to their operational airbase, and Doctor Lanschtein certainly did not enjoy every bit. But the speed was necessary for what he had in mind. As the car entered the bustling hangar, he took note of the organied chaos occurring around him. To the unobservant, it would seem to be a nightmare in motion. On one side, several crew members slid wafer-thin panels of clear material into a box while others danced around them with coils as thick as elephant trunks. On the other, an odd-looking machine caused the air to crackle in short bursts, only for the technician manning it to shake his head in disapproval.

He sourly looked at the spectacle before finally landing his eyes on the person responsible for this chaos. As he marched up to his target with determined annoyance, everyone in his way stopped and stepped back. They saw the all-too-familiar look in his eyes, and right now they wanted to have no part in the explosion about to commence.

"Doctor Aadil." Lanschtein stepped in front of the YELLOWSTONE subproject director. "Where are we with this?"

"Director Lanschtein! My apologies." Doctor Aadil wiped his thick hands and stood, his head bobbing out of habit as his heavy Pakistani accent peeked around the corners of his tongue. "We have been quite busy with-"

"Spare me the details, Doctor. Time is of the essence."

"Of course!" They began to pace the length of the aircraft as Doctor Aadil pointed at several areas in its frame. "We have already finished installing the external frame to the plane - we will have YELLOWSTONE up and running in no time. Captain Fairling is already being briefed on the specifics of the reconnaissance mission. Assuming the initial tests go well, this plane will be taking off in an hour."

Lanschtein nodded to himself. "I assume that YELLOWSTONE is acting normally?"

"Yes!" They walked over to the innards of the specialized camera system, its cords attached to the panels of clear material as technicians glanced at their readouts. "I have updated YELLOWSTONE's cognitive reinforcement pathways. The neural material is absolutely incapable of thinking of anything else besides the mission parameters. I can assure you that it will execute the plan flawlessly."

Their eyes met, and for a moment Lanschtein almost pitied his colleague. Thank god for dead Gray brains. "Good, because there's been a change in the mission parameters. We'll need to do a full scan of the globe, not just the United States. Can YELLOWSTONE handle and process that much data with the Kirilian lenses?"

"Th-The globe?" Aadil nervously licked his lips as he did the mental calculations. "I believe it is possible, but we will only have enough capacity to accomodate one pass. Then the plane will have to land, and I will have to replace all of the neural boards. If that is acceptable..."

"It will have to be." The sound of screeching tires got their attention. They both turned to look as General Armstrong stepped out of his car. "Is there anything else?"

"With respect, Doctor Lanschtein, I have looked over the file that you have sent, and I have some concerns. I believe that a conventional military response to contain the situation is no longer possible." Aadil looked at him with dread. "Please tell General Armstrong that I am recommending that we have BLUE THUNDER on standby."

Lanschtein could only stare at his colleague. "Are you mad, man?"

"The rate at which this pandemic is growing is neither additive nor multiplicative, but highly exponential, and I have no reason to believe that the human-analogous biochemicals these aliens are creating in such massive quantities have any countermeasures that we can prepare in time! If we do not contain it with certainty in the brief window that we have, we may not have a chance at a second shot."

Lanschtein's stomach knotted itself. BLUE THUNDER? God help them all!

"Snapshot 117, this is Lighthouse. You are cleared for takeoff. Be advised that there is a strong easterly air current at 15 angels, over."

"Copy that, Lighthouse. Gauges clear, green across the board. Yellowstone feed nominal."

"Copy that, Snapshot 117. Lighthouse confirms Yellowstone feed is nominal."

"Understood, Lighthouse. Snapshot 117, taking off. See you later."

That morning, Richard Fenstein had woken up to the strangest, most erotic morning he had ever had in his marraige. His normally reserved, somewhat temperamental wife had turned into a sex-hungry goddess overnight. No act seemed to limit her rapacious appetite for satisfaction - he had throughly fucked her cunt, her tits, her mouth, her breasts, and even her ass. She had practically bathed and swallowed copious amounts of his seed, with no limit in sight.

And that was what was niggling him at the back of his mind. Despite the intense pleasure blasting both their minds, he realized one thing: there was no logical, sane reason for his wife's behaviour to flip so suddenly. But that worrisome thought was starting to fade as the sun began to set. Other questions began to push their unpalatable way into his mind. How come he was still horny and functional despite not eating or drinking throughout the day? Why was he so aroused? Why wasn't his cock painfully insensate after more ejaculations than he could count? How could he have another rock-hard erection, another wave of fullness in his balls as they prepared to plaster Fiona with more seed?

"Mmmmmh, lovely." His wife smiled hungrily as she took stock of the cum-splattered room. No surface was left untouched by their debauchery, with a strangely opalescent sheen coating everything in sight. The oddly pleasant smell of tangy, spicy sex had permeated everything, but neither of them didn't seem to notice. "I still want more, honey." She licked her lips, gently pressing her bosom against Richard's face as her butt rubbed against his hard, wet cock. "But I think we can change it up with a little intermission."

"Mmmmh?" was all that he could say as the door creaked open. To his surprise, several blonde girls walked in, each of them appearing no older than his own son. In fact, the resemblance to their child was rather uncanny - if James was born female and was more Caucasian, he would have looked just like them. As they approached the foot of the bed with eager smiles, Richard noticed small, subtle differences between each one. Here was one who had a dimple on the left side of her face, while another had it on the right side. One had a mole on her bare shoulder, winking as she noticed his attentions wandering onto her. They weren't completely identical, save for their apparent hungry gazes.

But his observations were cut short as Fiona got off the soaked bed. Before he could say anything, the blondes began to make out with one another, their soft moans of pleasure tickling his ears as they slowly climbed onto his drenched body. Richard could only swallow in anticipation, their fingers daintily teasing his erection before slipping between their lips. Soon, they began to take turns licking his manhood, up and down its engorged length.

Richard could only grunt and struggle against his bonds. His muscles were already going through the familiar motions of orgasm again. Before he could stop himself, he came against their mouths, but the blondes didn't seem to mind it at all. In fact, they only paused to let him finish before greedily resuming their work, cleaning up every drop of his seed.

Fiona could only watch in amusement as her husband tried to resist another wave of ecstasy and failed in his struggle. "You know, love," she began, smiling as their gazes met, "if you wanted to be free and make out with these sluts, all you have to do is ask."

Confusion crossed his face, but Richard got the gist of what Fiona meant and looked at the handcuffs binding him to the bed. Somehow, they had transmogrified into pale, fleshy tendrils. With an unspoken command, they began to part, freeing him from his bonds for the first time that day. Without wasting another moment, Richard pulled the two closest blondes close and kissed them deeply. Their mouths tasted like ethereal sweetness, coaxing him for another. And another. And another.

With a smile, Fiona closed the door on the bedroom scene. The soft sighs of pleasure faded quickly as she descended to the kitchen. Around her, the walls were already coated with a thin layer of alien flesh, growing further and thicker with every passing moment. The afternoon air felt gloriously warm against her bare skin, the fading sunlight dancing off her naked body.

It would be time for a special family dinner soon enough.

"I'm home!"

Diane looked around the living room, setting her bag down on the sofa. Weird, she thought to herself. Neither one of her parents were around. Normally her dad would be writing his sermons in the living room while her mom cooked or knitted, but now it was quiet. Too quiet.

With a shiver, she closed the door and looked down. With a gasp of surprise, she realized that she had been nearly naked since her ... tryst at the Exxxotica, and quite wet. The sensation of sweat and cum, of wet thighs and sensitive clits didn't bother her at all. She barely remembered walking out of the sex store with James, stark naked and horny, as they rejoined Kara and Dana. They had said quick goodbyes before seeing her off to the mall's entrance, where she had climbed on the bus home with no one asking for her fare. The seat had pressed against her ass, her cunt soaking the fabric with her juices on the ride home. Then she had gotten down from a well-drenched seat, walked past several people on the sidewalk, and entered her house.

Hungry. Horny. Wet. She slowly blinked, barely aware of a strange lassitude enveloping her mind.

It was okay to be naked. No one noticed. It was okay to obey. It was okay to be this close to cumming.

Diane began to slowly walk up the stairs, conscious of an ever-growing urge to satisfy the hunger between her legs. Every step sent tingles of sensation up and down her body, causing her to halt till they subsided. After what felt like an eternity, she finally got into her room, closing the door behind her. Something vibrated gently against her breast, making her shiver at the sensation. She retrieved her phone from her jacket's inner pocket before sitting on her bed, shrugging the last item of clothing off onto the floor.

It was a video call from Trini's number. Curious, Diane accepted the call as her free hand slowly traced the outline of her clit on its own. "Mmmmh ... hey Trini."

"Hey, sweetness." The young girl was reclining against a brown sofa, naked as the day she was born. The soft sound of a guy moaning could be heard, and Diane could see the bare outline of a head bobbing up and down at the bottom of the phone's display. Trini smiled, her tongue licking her lips as her eyes met Diane's. "Mmmmm, good boy. Diane, why don't you ... mmmh ... be a good girl and drench your room, hmmm?"

She had barely finished the sentence when Diane felt her whole body clench, the sudden urge to cum explosively ripping the last of her self-control to shreds. "Ahhhhh!" Diane shuddered and spread her legs, her juices dripping down her thighs out with every orgasm that rocked her body. "Ahhhh! Ahhhh! Triniiiiiii!"

"Mmmm, you are so hot, babe." Trini's grin only seemed to grow brighter with every passing moment. "I want to, mmmmmh, introduce you to someone." She slowly pulled her arm back into view, and Diane saw that she had her fingers firmly ensconced in a young brunette's pussy. "Say hi to Cassie. Cassie, cum with, mmh, Diane here."

She could only bite her lip as another orgasm rippled through her. "Mmmmh, hi Cassie." Diane's eyes hungrily roved over the girl's lean body, her pert breasts and rainbow-colored hair. She probably worked out a lot, she thought to herself as she pumped her finger into her gloriously wet sex.

"Uhhhhhh." Cassie could only shudder and moan, her eyes almost dreamily blank. "I'm ... just delivering a pizzahhhh ..."

"Mmmmh, Trini." Diane shivered as their gazes met. "I'm just so ... mmm ... horny, and I can't stop coming ..." She moaned and leaned back, the slow sensation of pressure building up in her breasts and sex. She could feel her muscles clenching, and she could only hold on to the bed with closed eyes as wave after wave of pleasure crashed into her. With a gasp, Diane felt her clit swell and transform into a thick cock, great gouts of fluid shooting out of its tip as she tried to muffle her joy at her first ejaculation. "Mmmmmm!"

Finally, the urge to cum began to drop down from its fever pitch, and she opened her eyes to see Trini's ravenous smile at her state. "Oh, god, that was ... amazing!" With a shiver, she realized that her new sex wasn't the only thing that was wet - rivulets of liquid dripped down her nipples, mingling with her sweat and cum. "Oh wow ..."

"You're fucking amazing, babe. I wish James could see you right now." Trini beamed with approval as her companions moaned softly, her hands keeping them busy. "Now, just ... mmm, that's the spot ... just relax and let it all out."

As the words sank into Diane's mind, she dropped the phone and began masturbate both her sexes at a furious pace. The hot, glorious feeling of ecstasy began to rise once again, causing her whole body to vibrate with ever-climbing pleasure. With each motion, her room kept getting drenched with blasts of her seed, tendrils growing out of the cum-soaked surfaces as the alien flesh began to assert itself. In mere moments, the otherworldly material swelled and multiplied until it covered the entire room and its contents.

Tentacles emerged and grew, some supporting Diane's body as she lay on them while others drew nourishment from her nipples - or bathed in her ejaculations, teasing her extraterrestial manhood for more. Some merged and melded with others before sliding into her ass and cunt, pulsing as they wracked her brain with more ecstasy than it was ever meant to handle. As her moans reached a fevered pitch, Trini could only watch in hazy pleasure as the phone was raised by an alien tendril. If Diane was still conscious, she would have seen Cassie shudder as her own cock emerged, drenching Trini with a triumphant blast of cum before sliding into her corruptor's mouth.

But she was too far gone to notice that, or the orgy that was happening in her parent's room. Her father was held tightly against the wall by more alien flesh, several drones eagerly taking turns giving him a blowjob. On the other hand, her mother thrust her newly-fashioned cock into a drone's waiting sex, her eyes glassy with pleasure as she surrendered to her primal desires.

By 5.34 PM, three hundred and fifty eight people in Lafayette came, hot and wet, at the same time.

The sun was already on its way down when James realized that he had cycled home naked. Not that it had bothered him in the least - his mind seemed to be blanketed with a pleasant lassitude after his tryst in Exxxotica. He could barely recall what happened between that and arriving home, but it didn't matter to him.

He walked into his house, shutting the door behind him. Before he could turn around, a warm and tangy smell filled his nostrils as a familiar softness pressed against his head. He only had a moment before he realized that his mother had wrapped her arms around him. "Mmmm, welcome home honey." she whispered into his ear. "Someone smells very, very nice."

"H-Hi mom." James shuddered as he felt his mother's wet body glide against his own. He turned around, only to be kissed in a very tongue-heavy, unmotherly fashion. "Mmmmmh!"

Several long, hungry minutes passed before their lips parted. James realized that his mother's eyes were glazed with delirious pleasure, and that his body was already priming itself for another sexual session. He watched her kneel, tracing his erection with her fingers as her hungry gaze met his. "Mom, what ... unhh ... are you doing?"

"Mmmm, my sweet boy. All nice and thick like your father, and just as horny." Fiona leaned in and sniffed his cock, brushing her nose gently against his manhood. "Who did you fuck today, mmmm?"

He could only groan as he leaned against the door. Pre-cum was already dripping from his cock at the memory of the day's affairs, a liquid that was soon consumed by Fiona with gentle licks and kisses. "Ooooh ... gahhh ... Diahhhhhne ... and a girl, ahhhh ... at a sex shop ... Triniahhhh god!"

"Mmmmm, just them? I thought you'd have fucked your way into a harem by now." He could hear the smile in his mother's voice, approving and proud. "What about Kara and Dana? I can smell them too."

James could only moan as the memory returned to his consciousness. He and Diane had rejoined the sisters, naked and wet after their sex session in Exxxotica. After bidding Diane goodbye, he had wrapped his arms around them, their bodies relaxing as their voices became soft and unresisting. They wanted together to the lavatories, the sisters slowly kneeling as they were pushed down. Their mouths dreamily kissed his cock, drinking up his seed as they ministered to his balls with tender affection. They had emerged from the mall later that day with his hands gently caressing their bloated, cum-filled bellies as they made out one more time. "Mmmmuhhh ... I led them to the lavatories and ... ooohhh ... they sucked me off ... mmmmmh ... what's happening Mom?"

"That's my honey." Fiona grinned as she firmly turned her son around, letting his erection rest against the door. "Now, I'm about to finger my horny son's butt." She gently parted his buttcheeks, coating her finger with her own cum before slipping it slowly into his ass. "There we go."

"Gahh!" An unusually feminine lilt escaped from James's lips as he hung on, his self-control vanishing with each ecstasic second. His body was already responding to Fiona's temptations, changing here and there to accommodate his growing arousal. Some parts felt softer, almost fleshier in sensation. "Mohhhhhhhm!"
