The Xenomorph Breeding of Earth

The Xenomorph Breeding of Earth -- Part 1. Word count -- 6700.

Introduction:

This story contains xenomorph aliens from the Alien film series, although with some twists as gore and sex don't mix particularly well in my humble opinion. The aforementioned xenomorphs are owned by 20th Century Fox. All other aspects of this chapter are my own.

This story contains alien on human female sex. While this chapter contains straight sex only, it is building towards alien on human male intercourse which will be present in chapter two. This chapter (and most likely all the following in this series) will contain body modification, feminisation, breeding, oral, vagina and, anal sex between xenomorphs and humans. In some cases, the sex won't be entirely consensual.

In the near future:

The automated alien spacecraft passed Sol 3 as it continued to achieve its mission -- the seeding of worlds. The craft was too advanced to be detected by humanity's sensors on Earth. It released dozens of metallic eggs, each programmed to land on the planet's inhabited continents. Many were targeted at North America, with several clusters being launched into more rural areas in order to decrease the chances of discovery by the human authorities - at least until it was too late.

Robert Swift enjoyed driving in the US far more than he did in his native London. There were practically no traffic once you got out of California's largest cities. He'd been studying at Stanford for a year and was now looking forward to a summer break. Being 19, Robert had left the UK just as he hit the drinking age, only to find that America's drinking age was 21. How disappointing. Still, this trip to go camping in Oregon with several dozen other party-hungry students was sure to be great.

"How long until we're there?" Rob's only passenger asked. Kelsey wasn't too far away from your typical American rich girl next door. Blonde, busty and spoilt, Rob had dated her briefly before he realised that they weren't particularly compatible. They'd split up but remained friends with benefits. Sexually, they got on like a house on fire.

Her busty chest heaved with a sigh. Kelsey's top was almost skin right, giving him a great view of her boobs. His cock twitched.

Rob tapped the Satnav. "Less than a an hour,"

"Arugh, I feel like I'm about to pee myself!" Kelsey pouted.

"Fine! We'll pull over at the next service station we see."

"Thanks! I'll make it worth your while," Kelsey winked.

Indeed she did. After stopping for the loo break, Kelsey pulled Rob's semi hard dick out of his trousers to give him some road head.

Hey, slow down Kelsey! I'm trying to drive here," But Rob wasn't complaining too loudly as her tongue teased under the glands of his uncut cock. In no time, his 7" manhood was fully erect. Kelsey wasted no time deep throating him, making Rob clench his hands on the steering wheel.

"Mmmmm, fuck!" Kelsey pulled her mouth away. "Do you love it when I suck your cock?" She asked, with a grin on her face.

"Absolutely darling!" Kelsey continued to tease Rob's cock with a hand job as she put forward her proposal.

"So... You know how much I want a threesome right?" Rob simply nodded.

"Well... I can tell Darrell wants to fuck me, "

"Him and every other bloke in California," Rob interjected. Darrell was a about the same height - 6ft 3, as Rob but there the similarities mostly stopped. Whereas Rob was certainly more of a geek, albeit one who swam a lot to work out, Darrell was pure African American muscle. He was an American football player, although he also had brains, not purely brawn. Darrell had certainly bedded a lot of girls at Stanford University. Rob hadn't hit anywhere near those numbers but he had to admit that is RP British accent did open legs in the States. Due to his swimming, he also did his best to keep his body hair shaved, especially his chest and pubes.

"Does Darrell know that it's going to be a threesome and not just him and you?"

"Yep, we've been texting and he's happy with that,"

"Are you sure that you can handle him?" Rob had heard that Darrell was fairly well endowed.

"I can handle him in my cooch! You'll get my butt," Kelsey said before returning her mouth to Rob's dick.

"Oh fuck yeah Kelsey, you know how much I love your sexy arse," Rob strained himself to keep his attention on the road while she brought him closer to climax.

"So you're down?" Kelsey asked as she brought him to the brink of orgasm.

"Yes, yes, just make me cum already!"

She did just that. Her tongue continued to lick the sensitive understand of Rob's dick while she rubbed his balls.

"Ah, yes I'm cumming!" Rob exclaimed. Kelsey deep throated him and made sure to swallow every drop of his hot cum.

"I love it when I get my way," Kelsey said as she pulled her mouth away. Rob was in his post-orgasm haze and tried to return his attention to the final stage of the drive to Oregon.

The smell of weed and the sound of voices carried through the forest as Rob and Kelsey hiked up to the campsite.

"It sounds like they've started the party without us!" Kelsey said.

"Don't worry, I've got plenty of booze for the both of us," Rob replied. The light from several camp fires illuminated the way to the clearing. Burning embers rose into the sky and the noise of wood crackling filled their ears.

They reached the clearing to see several dozen of their fellow students drinking, smoking and generally socialising.

"Yo! The limey is here! I thought you Brits were meant to be always on time," Steve, one of Rob's classmates shouted over.

"Blame Kelsey! She spent too much time trying to do her bloody make up before we left," Rob retorted.

"Hey! You said you wouldn't tell anyone that!" Kelsey exclaimed. She then left Rob's side to over to a nearby fire where some of her girlfriends were.

"I'm surprised you even made it at all with that piece of shite you drive," Rob ribbed Steve

.

"We almost didn't. I had to get a jump-start when I filled up with gas," Steve passed Rob an open Bud. "So did Kelsey keep you entertained?"

Rob simply nodded, although with a smile on his face. "Ha! I knew it!"

At that moment, another half a dozen guys entered the clearing. Darrell and some of his American football team had arrived with more beer. Rob glanced over to Kelsey -- her attention, as with several other girls was focused on Darrell and his entourage.

It quickly began to drop dark. Some men and women paired off and went into the forest that surrounded the clearing but most of the group remained around the camp fires drinking. Rob was starting to feel buzzed of the beers he'd drank.

"It's been too long since I drank this much. I swear I didn't used to get so tipsy off this amount. I must be out of practice," Rob muttered to himself as he went to take a piss away from the clearing.

As he began to walk back towards the camp fires, he almost bumped into Darrell and Kelsey.

"Hey Rob! Good timing!" Kelsey said slightly drunkenly.

"We gonna do this?" Darrell asked. "This bitch is in heat!" Even through his vest top and baggy pants, it was easy to tell he had an enviable body and the shape of his semi hard dick was visible. Rob instantly was hit by a wave of self consciousness even though he knew that he wasn't in a bad shape and his cock was also above average. Kelsey giggled. She was definitely tipsy.

"Yep, I'm game," Rob replied, trying to play it cool.

The trio walked about 100 yards away from the clearing -- far enough that they'd have privacy but close enough that there was some light. It was a mild night even away from the fires.

Meanwhile, the metallic egg opened. The being inside could sense a compatible host was nearby. It crawled towards its target, following the pheromones. Yes, it thought, this human will be the perfect host. The alien was a face-hugger; it was dark grey with several skeletal legs and a tail but not much else. It moved almost silently towards its prey.

Kelsey's DD tits were certainly great eye candy. Neither Darrell or Rob could keep their eyes off her as she began to strip off.

"C'mon boys, don't make me wait!" She laughed. Darrell took off his vest top revealing his six pack. Kelsey visibly licked her lips. Rob, again was hit with thoughts of self consciousness.

Maybe I ought to add some weights to all the cardio I do, he thought to himself. He took a final swig of Bud and pulled off his T-shirt. Kelsey smiled at him briefly before her attention returned to Darrell's bugle. The size of his cock was visible through the white briefs he was wearing.

Darrell saw her checking him out. "Like what you see girl?" Kelsey could only nod in reply but how erect her nipples were gave away how turned on she was.

"Come over here and suck this big cock!" Darrell then changed his focus to Rob. "You! Get that pussy wet for me." Neither Rob nor Kelsey needed telling twice.

Kelsey practically crawled over to Darrell, gazing up at his 9 inch black cock bulging through his underwear. Rob knew from his sexual discussions with her that she'd never had a cock that big in her. Even he had to admit to himself that he was looking forward to seeing Kelsey's tight pussy being split by it. Slowly she pulled down Darrell's underwear, freeing the python and his trimmed yet wiry pubes.

"Oh yeah, beg for my cock!" Darrell told her. Kelsey did just that.

"Mmmm, please let me suck your big black cock Sir? I need to taste it!"

"That's a good slut." Kelsey then got to work, opening her red lipstick coloured lips around the black dick. She immediately let out a quiet moan as she realised that she was about to experience two fantasises for the price of one.

Rob got down under Kelsey's belly. He then pulled down her thong to reveal a very wet, pink, and perfectly hairless pussy. Her juices were already practically flowing out of her cooch. He wasted no time sinking his tongue into the hole, immediately tasting her, before slowly moving his tongue back towards her clit. Kelsey responded with loud but muffled moans of pleasure.

Kelsey had received oral from several guys and girls since she'd lost her virginity at 16 but she had to admit that Rob was actually the best pussy licker out of all of them. The only times he failed to get her off was when she made him stop because she wanted a dick in her immediately. The fact that she had a huge cock in her mouth really was the figurative cherry on top and she'd honestly never been so horny. She could taste Darrell's salty pre-cum as her tongue danced around the glans of his cut cock.

"Fuck yes girl, keep doing it just like that!" Darrell encouraged with his deep voice. He'd received plenty of BJs from a variety of girls especially since he'd really got serious playing football. Kelsey wasn't the best he'd had in terms of technique but her enthusiasm was a big turn-on. She was still concentrating on the head of his oversized manhood which he was certainly enjoying. But Darrell liked to have his girls deep throat his cock until they gagged. With that in mind, he gently but insistently began to push his cock deeper into her open mouth.

Kelsey's blue eyes opened wider as she felt just how thick Darrell was. Had she bitten off more than she could chew? Maybe, she admitted to herself, but it was worth it! She concentrated on breathing through her nose to keep herself from gagging on the obstruction.

"Yeah, that's a good bitch. Take this big black dick," Darrell told her. Despite the slight fear of choking that was somewhere in the back of her mind, Kelsey was on Cloud Nine. She could feel her throat taking his meat deeper, slowly but surely. Muffled moans escaped from her abused mouth.

Meanwhile, Rob was really going to town on her vagina. His tongue was bringing Kelsey ever closer to the brink of orgasm. The taste of her honey was something he really savoured but now it was time to get his fingers involved too. Two of his digits easily slipped into her soaked hole. Instantly, Kelsey's pussy clamped down on the invaders. Her muffled moans intensified.

But Rob was only getting started. He manoeuvred his fingers towards her G-spot and once he felt the slightly spongy target, he began to rub it while keeping his tongue locked on Kelsey's sensitive clit. His spare hand was gently massaging Kelsey's butt cheeks as she squirmed under the onslaught of pleasure her brain was processing. Rob could feel his own cock at full mast inside his trousers. He really did love eating ladies out and he knew from experience that she was getting closer to climax.

Time to really work her up, he thought to himself. He slipped a third finger into Kelsey's vagina, keeping her G-spot firmly as the centre of attention. His other hand now slowly moved towards her asshole. The thought of fucking that really was a huge turn on for Rob. But first it was time to get that hole warmed up.

Taking some of the copious juice coming out of her pussy, Rob lubed up another finger and rubbed it around Kelsey's tight butt hole. Instantly he felt her tense up as she felt the digit probe her rosebud.

Kelsey knew that she was close to orgasm even before Rob started to push his finger into her ass. She wasn't a one orgasm and done kind of gal -- although multiple orgasms were not as common as she'd like. Still, she knew that tonight, being the centre of attention of this threesome would definitely lead to many.

"Mmmmmppphhh!" Was the only noise that came out of her mouth due to many inches of Darrell's dick lodged in throat. The waves of pleasure radiating from her vagina and ass spread throughout Kelsey's body as she climaxed explosively. She felt her pussy squirt onto Rob's fingers as she saw stars.

Darrell felt her orgasm and used the opportunity to push the last two inches of his thick cock fully into Kelsey's stretched mouth. He felt some resistance but it slowly went in as her first orgasm began to subside. The bugle in Kelsey's throat was visible which was another turn on for him. Kelsey reopened her eyes, looking lustfully back at him.

The source of the pheromones was growing much stronger to the face-hugger. It was getting very close to its target. While there was a large group of humans not too far away, the alien was fully focused on the three humans in very close proximity. The alien had no eyes but could navigate and hunt using distortions in the electromagnetic field once it got close enough. And it was now close enough. It slowed its movement in order to maintain the element of surprise.

Rob thought he heard some bushes rustling but he was far too engrossed in getting a second finger into Kelsey's sexy arse to look up. Her hole accepted it without too much hesitation. He could feel her pulse beating heavily through her orifices as he pumped both pussy and ass with his fingers while he continued his oral assault on her clit. Rob knew that he was pushing Kelsey to a second orgasm and he was determined to make it happen soon.

Darrell had now began to fuck Kelsey's mouth with every inch of his giant cock. Her tight throat was bringing him very close to the release of his nut. His two hands gripped the back of her head, holding it in position.

Kelsey felt like a true slut and she was loving the way Darrell was using her mouth. She was using all her spare energy to maintain her breathing through her nose to stop herself from gagging. She could tell that Darrell's pre-cum was thicker and that he was getting closer to shooting down her throat. Kelsey swore that she could feel his cock expand as Darrell's orgasm started. She felt him grab and pull her head so his cock really was balls deep in her throat.

"Oh yeah girl, swallow that nut!" Darrell exclaimed.

Kelsey did just that, although she didn't have much of a choice considering Darrell's cum was being ejaculated straight down into her stomach. The feeling of the hot cum shooting into her throat combined with Rob's fingers working on her backdoor and vagina were enough to propel her to another climax.

Rob absolutely loved making a woman squirt, especially during anal play. Kelsey's second orgasm lead to her squirting directing onto Rob's open mouth which he mostly swallowed, as she swallowed every drop of Darrell's seed.

It was then the face-hugger struck. Emerging from the bushes faster than any of the three could comprehend, the alien attached itself onto Darrell's face. Kelsey felt Darrell pull away aggressively. Looking up in surprise, she let out a high pitched scream and scrambled back away from the football player, her knees making contact with Rob's head in the process. Rob shouted out more in surprise than pain.

"What the f...?" Rob then saw Darrell with both hands to his face trying to pull a dark grey skeletal animal off his face. But what kind of animal was it? A weird spider? He'd never seen anything like it. Was this some kind of elaborate prank? Rob, still wearing his and trousers, and Kelsey, totally naked apart from a narrow thong, both stood back. Rob deliberately moved himself in front of her although he didn't think he'd be particularly successful in protecting her if this thing took down Darrell.

The face-hugger's limbs had folded themselves fully around Darrell's head. It's eight spindly looking legs were deceptive strong and Darrell had no joy trying to pull it off. Once attached, it immediately injected him with an paralysis agent. This sent Darrell to the ground within seconds. It was then that the face-hugger really got to work. It's penis like appendage entered Darrell's non-resistant mouth, although neither Rob or Kelsey could see this as the body of the alien blocked their view.

"Rob, is it killing him?" Kelsey asked. Her voice trembled with fear. Rob didn't answer straight away. He could see from the way Darrell's chest was heaving that he was still breathing.

"I'm not sure. Your phone is back at the camp, right?" Kelsey nodded. "Bugger. Mine too. Can you make a run for it?" She didn't reply but instead pointed back to the Darrell's prone form.

The face-hugger injected it's DNA altering liquid via it's appendage directly into Darrell's stomach. Once it had finished its duty, the creature unattached itself and simply died. However, the transformation it caused with its liquid started to happen in front of Rob and Kelsey's eyes.

Darrell's entire body's colour started to turn from his natural dark brown skin colour to midnight black. He looked less human and more insect like, but kept a lot of his muscular definition. Several large spines began to grow out of his back and a couple of smaller ones out of his arms. From Darrell's lower back, a large tail grew, reaching over six feet long. His head no longer looked at all human -- it was now a giant, bulbous, banana shape with no eyes or ears, only a large jaw. The top of his head was a shiny, smooth black.

Rob's first thought was that Darrell had transformed into a giant preying mantis, although he knew that wasn't that much of a correct observation. Rob heard Kelsey emit a loud scream from right behind him. Glancing back towards "new" Darrell, Rob had to admit his heart about stopped beating.

"Darrell" had brought himself to his large, clawed feet.

"What are those Four Fs my science teacher used to say animals follow? Fleeing, fighting, feeding and fucking. Somehow I don't think this bugger is going to flee. So we're either fucked figuratively or literally." Rob thought to himself. He turned to Kelsey.

"Get ready to run in 3...2...1," he whispered. They turned but neither of them made it two feet before they were hit by a spit-ball of resin aimed at their legs. Both Rob and Kelsey tumbled to the forest floor.

"Ow fuck!" Before either of the pair could attempt to free themselves from the sticky substance "Darrell" was on them.
