Alien's Horny Invasion

Author's Notes: This story is inspired by the long-gone Literotica story "Aliens Use Sex to Invade". It is primarily Science Fiction and Fantasy but has elements of Gay Male, Group Sex, Lesbian, voyeurism, and Incest/Taboo. All Characters are over 18 years old and are not intended to be based on real individuals.

Additional Notes: I acknowledge there may be some confusion with the names of certain characters. For clarification, I messed up in the editing process. Betty is named after Betty White and Bethany was the one named after Bea Arthur, not the other way around. I apologize if there was some confusion.

Julienne Gray, Age 40, Genetics Researcher, Center for Disease Control.

It was the wee hours of the morning when Julienne received the transmission from Mars. She was working on a project in her lab when her console beeped with an urgent notification. She almost ignored it until she saw that the origin was Mars.

The moment she opened the link, she was pleasantly surprised to find a personal message from Jorden, her cousin. The message contained detailed information about an alien spacecraft crashing onto the surface of Mars, a parasite that was spreading through the colony, and the genetic specifications of the virus itself. The message also requested that Julienne find a cure soon before it spread to Earth.

Suffice it to say, Julienne was terrified of what she had learned and the first thing she did was contact her superiors at the Department of Health and Human Services in Washington, D.C., inform them of the parasite, and request permission to research a cure. For some fucked up reason, however, her superiors dismissed her claims without any evidence. They refused to do anything about a so-called plague on Mars.

Undeterred, Julienne began to research a cure nonetheless. She began by going through her cousin's information, looking at the genetic structure of the parasites, and looking for any kind of weakness they might have. After an hour of searching, however, she came to one conclusion: Without knowing their origins, she wouldn't be able to find a means to combat the parasites, at least not one without experimenting on a sample.

Thus, she began again, this time going over all of Jorden's research notes and discoveries, looking for some hint she could exploit.

Private Brad Anders, Age 19, Military Division, Earth.

Peter and the Anders Kids had gotten dressed, left the tram, and were now exploring Atlanta. Their goals were clear, Peter would find and seduce Doctor Julienne Gray, while the Anders kids would split off into pairs and begin their seduction of the populous, to spread the gift of the Zzij to the people of Earth. Peter, for his part, had managed to book an appointment with the CDC, namedropping Jorden Gray to do it. He couldn't get into a meeting with Doctor Julienne Gray, but that wasn't important, as long as he got to plant the seeds of doubt among her coworkers.

Brad, meanwhile, was with his sister Betty, as they ate a late breakfast in a local diner. Bart and Bethany had split off from them as soon as they departed the tram. None of them had ever visited Atlanta before, but the four siblings were eager to see the sights, meet the locals, and fuck their brains out.

All four of them had fucked at least half of the Mars colony since the orgy in the barracks, as well as each other. Brad, for his part, was a pretty slim guy, lean with a pronounced muscle structure. Since the orgy, however, he had bulked out and had now acquired very prominent pecs, abs, and strong round arms and legs, providing the image of a fit wrestler, like Cody Rhodes from the 2010s. His siblings all had very similar features. Being quadruplets had the bonus effect of having similar bodies.

Betty, for her part, had large D-cup breasts and wide hips, with pronounced abs and tight glutes. All four siblings had dirty blonde hair and hazel eyes. While Brad and Bart had the military trim, Betty and Bethany decided to have ponytails, but now that they were liberated, Betty had decided to grow her hair out. She let her ponytail grow in the last month and now had shoulder-length hair.

As they ate, they couldn't help but notice that everyone in the diner was stealing glances at them. Betty slowed down her chewing and glanced off to the side, over Brad's shoulder, at a pair of women, who looked to be in their early thirties. Both women were speaking in hushed tones and stealing glances at Brad, and Betty noticed their eyes were gleaming with delight and lust.

Brad, on the other hand, was casually looking at a table in the corner, where four guys in their late teens to early twenties, were all ogling Betty, admiring her fit figure and large breasts. Based on the looks they were giving her, Brad thought they wanted to fuck her at the same time, and got a twitch from his cock at the thought of watching them gangbang her, and possibly joining in.

Their parasites also began to sense the change in their bodies as they reacted to the sexually charged glances they were getting, and sprang into action. Betty, getting an idea, suddenly stood up and walked over to the pair of thirty-somethings and sat down next to the one sitting with her back to Brad.

At the same time, Brad got up and walked over to the guys, sitting next to a lanky kid with black hair and lip piercings.

Betty quickly introduced herself and told the two women that she couldn't help but notice they were staring at Brad, not mentioning that he was her brother. She then said the words, "Interested in a threesome?"

Both women looked shocked at the mention of the word 'threesome' but one of them, a tall woman with long brown hair and matching eyes, blushed and asked, "With him or with you?"

Betty smiled, "Yes." she said.

The woman sitting next to Betty, a husky-looking woman with bleach-blonde hair and light green eyes, cleared her throat and said, "Don't be ridiculous, Lena! She doesn't want a threesome with us! Look at her, she's barely 20! What could she want with two old women like us?"

"I'm 19." Said Betty, "And I could want a lot of things from the two of you, like knowing how to eat pussy, for one!"

"Language!" Said the brunette, "We're in a public diner, for Christ's sake!"

"Sorry." Said Betty, feigning an apology. In truth, she didn't care if she was being loud or rude. Her goal was to get them aroused for her and Brad. Their silent agreement was to seduce both groups and get the guys to fuck her, while Brad fucked the women, then get the groups to fuck each other.

"It's not a problem, young lady." Said the blonde, "I'm Helen, and this is my friend Lena. We work at a law firm down the street."

"Nice to meet you both, I'm Betty Anders." Said Betty in response, "The guy you were devouring with your hungry eyes is Brad, and he's a god in the bedroom!"

Lena's eyes flashed with anger while Helen's burned with passion.

"I don't know what you're talking about!" Said Lena, angrily, "I think it's time to leave! Come on, Helen, let's pay and go!" She got up to pay, but Helen stayed in her seat and glanced over her shoulder at Brad.

"How...how big is he?" she asked, hesitantly, when Lena went to the host to pay.

Betty, staring into Helen's eyes, smiled wickedly, "Ten inches!" She said, "And he's as thick as a soup can!"

"Ohhhh...." Helen moaned out.

"He eats pussy like a king, fucks like a god, and is strong enough to carry you and not get tired. He can go all night and never go soft, and he's very loving and gentle, that you'll feel like you've died and gone to heaven, where every angel has been instructed to bring you to orgasm." Betty explained as she grew wet from the description. The parasite within her was fueling her libido, and giving off a pheromone overload, making her radiate arousal.

Helen, for her part, was given a very vivid image of herself riding a beautiful cock and wanting to fuck hard. She wasn't old enough to be a cougar by any means, but she desperately wanted some of Brad at this very moment! She immediately tapped on Betty's shoulder to let her out and quickly went to the restroom to masturbate. Betty, in turn, smiled and waited for Lena.

Meanwhile, Brad's conversation with the guys went similarly beneficial.

"Hi there, what's shaking?" Brad asked, sitting down.

The four guys scoffed, "Boy, someone's vintage, isn't he?" asked the Goth kid with the piercings, "Did you drive a time machine from the 1990s or some shit?"

"No, just making small talk." Said Brad, deflecting, "I noticed you guys undressing my girl with your eyes!"

"We didn't mean anything by it, man!" Said the guy sitting opposite the Goth boy, "I'm Steven, this is Seth." he added, gesturing to the Goth guy, "That's Bill and Danny."

"Nice to meet you all, my name's Brad. My girl is named Betty." Said Brad, "So, from glancing over at the four of you, my best guess is that you want to gang-fuck her. Am I right?"

Bill, the guy sitting next to Steven, a lean boy with a buzz cut and the tattoo of a black bear on his neck, blinked, "What makes you think that?" he asked.

Brad smirked, "You had the look of someone who wanted to stick his dick in her ass!" He said, "Don't be ashamed, I got that same look the first time I did it. It's fun! She's tight all over, and she's a wild one. She'll scream when she cums and she'll beg for more cock for hours. She never gets tired, and the more you fuck her, the less you'll get tired."

"That's impossible!" Said Danny, a lanky mirror image of Steven, only his hair was red instead of black and he had piercings on his ears and tongue, "No girl is ever that thrilled to fuck four guys at once! And it's not possible to go for hours. Everyone gets tired eventually!"

"I never said you'd never get tired or want to stop!" Said Brad, "What I'm saying is when you fuck Betty, and I know you will fuck her eventually, you'll be so turned on by her, you'll be envigorated to continue long after you'd normally get tired."

"How?" asked Danny, incredulously.

"We have a way of making you last longer," Brad added, grinning.

"Drugs?" asked Bill.

Brad shook his head, "Natural remedy! Completely organic."

"What is it?" asked Seth for the first time. He was the smallest of the bunch, thin with a wolf's tail grey-dyed haircut.

"Something that I can't share unless you agree to fuck Betty!" Said Brad, "You want to last for hours, you fuck her first! The second you cum inside her, I'll share what we have! Deal?"

The four boys exchanged glances before they all nodded in unison. Brad smiled, and gave him a small piece of paper with an address on it, "Come to this motel room tonight at Seven PM! You won't be disappointed!"

With that, Brad stood up and left the booth, walked to the entrance, and paid for his and Betty's food before he stepped outside, where he waited for Betty to finish.

Betty, after getting up from her booth to let Helen head to the restroom, sat back down as Lena came back to grab her coat. Lena glared at her as she sat there, sitting on Helen's things.

"I think you've overstayed your welcome, Betty." Said Lena, sourly, "Why don't you take your boyfriend and get out of our sight!"

"I will, once I have your assurances you'll be meeting Brad later and getting the orgasms of your lifetime!"

"There's no fucking way I'd ever meet a pervert on a rendevous!" Lena practically snapped, "If you don't leave us alone, I will call the police on you!"

"Then you'll be missing out on the fucking of the century!" Said Betty, sadly, "Don't you want to cum hard? Don't you want your pussy to scream with ecstasy? Or do you want to go back to your law firm where you're more than likely to sit at a desk for long hours and daydream about the hunks in suits as they fuck their secretaries and leave you alone, lying in the dust?"

Lena glared at her, "I'm an associate to a name partner!" She said through gritted teeth, "If I want to fuck an escort, I'd go to Vegas!"

"We're not escorts!" Said Betty, standing up, "We're liberally-minded people with a very modern view of sex! I can share a moment of pleasure with you if you agree to meet with Brad tonight around 7 pm."

"I would never meet some random man!" Said Lena, angrily, "You're insane!"

"Yet Helen's aroused beyond belief!" Said Betty, just as Helen emerged from the bathroom, looking a bit dishevelled. She walked over to their booth and grabbed her bag and coat.

Lena glared at Helen, "What were you doing in there for so long?" She asked, then realized what Helen had been doing, "Never mind, let's go!"

"Wait!" Said Betty, "Just one more thing!"

"What?!" Asked Lena, angrily.

Betty smiled sweetly as she turned to Helen, "For your trouble, here!" She said, before cupping Helen's cheeks in her hands and leaning in for a kiss. Their lips met as Betty sank her tongue deep inside the other woman's waiting mouth. A collective gasp from the diner patrons sounded as Betty kissed Helen long and deep. The guys at the table Brad had left behind were smirking and high-fiving each other at the blatant display of lesbianism.

Helen was in a state of shock when Betty removed her mouth from hers. Betty, meanwhile, smirked and slipped a note into Helen's bag, "If the two of you change your minds, meet us at this address tonight at 6:45 pm."

With that, she left the diner, leaving Lena and Helen staring at each other in bewilderment. After a long pause, Lena growled and grabbed Helen's arm, dragging her out to their car. The two women drove back to the law firm and returned to work. They went to their offices and Lena did her best to ignore Helen for a long time.

Helen, for her part, was in a state of shock with her mind full of haze. While she had experienced kissing a woman before, nothing compared to when Betty kissed her today, and to make things stranger, it left a tingling feeling in her loins, as if something was actively hyping up her libido. She felt herself sopping wet as soon as they got off the elevator on the fifth floor.

Unbeknownst to her, a parasite had travelled from Betty's mouth into Helen's body, travelled down to her limbic system, and was now releasing chemicals within her body. Her breasts started to heave and grow, and she felt a warmth in her loins as the arousal from the kiss made her pussy explode in micro-orgasms the more she thought about it. Then her mind switched over to the mental image that Betty had implanted in her brain about Brad, and suddenly her pussy felt like it would explode in a massive orgasm right there while she sat in her office.

Without warning, Helen burst from her chair and ran to the restroom, plopped herself onto a toilet seat and hiked up her skirt, plunging her fingers deep inside her pussy, and began to frig herself! She stuck three fingers deep within her and began pumping herself until she came, squirting juices across the stall, where they splattered the base of the door and started dripping onto the ground.

Meanwhile, Lena was seething at the sexual display in front of her. Lena was a Traditionalist, damn it! Never in a million years would she ever consider meeting a strange man, a younger man, in a motel room late at night, especially for sex! She was no stranger to sex. She lost her virginity at 18 to her boyfriend at the time. She thought he'd be safe and that he'd protect her. That they'd do it together and get married later that year after graduating.

But it was not meant to be. The sex sucked, he came inside her within two minutes, and afterward, he dumped her for a bimbo slut cheerleader, left town after graduation, and joined a hedonistic nudist colony in Florida.

Scorned by her experience, Lena had denounced all men and focused on her career! No man would ever make her feel like shit again! She would never allow it! Sure, she would ogle men in the intervening years, but when it came to socializing and dating, and any attempts men made to get her in bed, she flat-out refused to even consider it! She would look, but never touch, and certainly not strip naked for a man ever again or lie on her back and take it with her legs spread open!

No man would ever touch her or break her heart again! So why did Betty's words sound so appealing?! Why did the thought of an explosive orgasm bring her mind back around to sex after so many years? What did the boy have that her former lover did not have? What made Brad different from the cuck that came in two minutes?

She shook her head, angrily, just as the door to her office opened, revealing Helen, looking twice as dishevelled as before. Lena stood up and went over to her, closing the door in the process.

"What the hell is going on here?" She asked in a low tone, "Why are you asking like a slut?"

Helen stared at her without saying a word, before she thrust her mouth forward and took Lena in a big wet kiss. She locked her lips and flung her arms around, hugging Lena and preventing her from escaping. The two women kissed for a long moment before Lena finally got up the strength to break free.

Lena spat out saliva as Helen took a deep breath.

"What the actual fuck, Helen!?" Said Lena, now thoroughly pissed off.

Helen ignored the woman and moved to kiss her again, but Lena held out a hand and stopped the woman in her tracks, "I don't know what's going on but..."

But before she could do anything, a sharp heat shot through her mouth and travelled down towards her breasts, passing over the small B-cups before travelling into her loins. Within seconds, her breasts began to swell as her vagina became overwhelmingly moist. The next thing either woman knew, they had stripped off their clothes and were scissoring under the desk, furiously moaning and grunting, in between giving each other very passionate kisses. Soon after, they were in a 69, bringing each other to orgasm.

After their third hour, they had finally ended their sexcapade and were cuddling up against the wall, Helen planting Lena with gentle kisses along her neck and shoulder.

"This was fun!" Said Lena, thoughtfully, "I've never done anything like that before."

"Never?" asked Helen, "Not even once?"

Lena shook her head and told Helen of her terrible experience with sex. It took her less than ten minutes to go into full detail about how offensively bad her first time was and how she vowed never to do anything like that again.

Helen listened and when Lena was finished, held her tighter, pinching her nipples and offering soothing words of comfort.

"I've got something to tell you." She added, after a long silence, "I'm going to meet that couple at the motel tonight. I want you to join me!"

Lena looked over her shoulder and stared at Helen for a long time before she silently nodded.

*************************************************************************************************************

Helen and Lena sat alone in Lena's car for a long time. It was 6:38 in the evening, and the sun was setting. They were told to wait until 6:45 pm to meet with Brad, but they had grown impatient in their silence.

Just as they were about to give up and drive away, Lena spotted a small hatchback approach and park. They paused and watched as four guys in their 20s hopped out and approached one of the rooms. One of them knocked and the door opened, revealing Brad standing in the doorway. He gestured for them to enter and then closed the door behind them.

"What's all that about?" asked Helen, curiously.

Lena shook her head, "If they're going to rape us, I'm fucking done!" She said, her anger returning. Just as she was about to start her car, a gentle tap on the passenger side made them jump. Betty was standing there, a smile on her face.
