The Xenomorph Breeding of Earth Ch. 01

Darrell's new objective in his new body was very different to his old one, although the method was certainly familiar. He was to create a Hive here on Earth and to do that, he needed to Fuck. He didn't care about the gender -- his DNA altering cum combined with his new ability to implant eggs in any compatible creature would see to that. He wasn't technically even a "he" anymore but a hermaphrodite. But Darrell's brain didn't dwell on that as he still had something that acted and looked like a male organ between his powerful legs. He could feel an animalistic sexual rage building inside of his loins. To two humans lying trapped in his resin only feet away would do perfectly.

Ron felt sick to his stomach with fear as the xenomorph stomped closer to them, hissing quietly as it did. He couldn't tell accurately as he was half lying on top of a naked Kelsey on the forest floor, but he estimated Darrell was now over seven feet tall. His black skin and oversized jaws and claws gave off the impression that this creature truly was an alpha predator and would easily best any human. He tried to pull out of the resin tying his ankles down but that achieved nothing.

Kelsey was dazed. She could feel part of Rob lying on top of her but she was too stunned to feel much pain. Her head swam with incoherent thoughts, none of which really mad any sense. A giant monster, here? You must be tripping! Her befuddled brain told itself. Only then did she feel a moist, clawed hand pull her to her feet. Looking into the monster's totally inhuman face, Kelsey tried to scream. But she was too scared even to do that properly.

Darrell had his first prey. He also still had his human memories -- he remembered how he'd been excited about fucking this human female, Kelsey. These thoughts further filled him with the lust to breed her. Between a slit in his new pelvis, his new sexual organs began to appear.

"Oh my God. NOOOOO!" Kelsey found her voice. She had assumed that she was about to be killed and eaten... But new Darrell obviously had a different plan for her. Although she was very concerned that the size of his monster cock would kill her.

It looked more like it belonged on a horse rather than a man. At least a foot long, the midnight black phallus followed by a huge black ballsack grew out of the Xenomorph. The ribbed head of the giant dick merged with a smooth shaft about 5 inches down at a small but noticeable ridge. As with the rest of Darrell's new alien body, there were no hairs to be seen.

Kelsey felt the Xenomorph free her from the resin only to move her away from Rob towards the centre of the clearing. She thought about resisting but the creature scared her far too much for that. Her eyes met Rob's as he watched on in fear and some disgust at what he took had realised was about to happen to her.

Rob had his own thoughts - the beast was obviously going to be distracted for the moment, but he did wonder what it would do with him -- was he to be its post sex meal?

Darrell's new body was ready. He could feel his instinctive need to seed Kelsey for the new Hive building uncontrollably. Careful not to hurt her relatively fragile human form, Darrell turned her around and bent her over at the waist. He then lowered his huge frame down to the point where he could look directly at her smooth pussy. The amount of pheromones it was emitting was driving his alien sensors wild. He had to taste it. His forked tongue left his jaws, making contact with the flaps around Kelsey's vagina. He felt her immediately tense up, both with fear yet also with unexpected anticipation.

Kelsey tried to ignore the alien tongue currently licking around the outside of her pussy, but her body reacted instinctively. While her sexual arousal had disappeared since Darrell had become a monster, she could feel it rising within her, fighting against her disgust and fear.

"Mmmph!" She let slip through her lips, as Darrell's tongue located her sensitive clit.

Yes, Darrell thought, this human bitch is definitely ready to be bred. His tongue entered her, giving him a taste of her depths as he prepared her for the fucking of a life time. He used his tongue to explore her, before pulling it out and raising his pelvis to ensure his new organ was aiming straight into her snatch.

Kelsey had reluctantly enjoyed the feeling of the tongue teasing her clit and then way it had explored the inside of her pussy. It had spent several moments playing with her G-Spot which had really began to work her up. Now though, her fear returned. She could feel the heat of the giant Xenomorph cock between her legs. She felt Darrell's clawed hands on her shoulders holding her in position. She could see Rob watching on in horror at what was about to happen.

Then, she felt it. The head of Darrell's cock made contact with her hole, making her gasp. Initially it didn't fit, but after he rubbed it against her slit for several seconds Kelsey felt the invader start its long journey into her tight vagina.

Via Darrell's Hive mind connection, her knew that his pre-cum would help alter a humans orifices to help his giant appendage fit. It worked exactly as advertised and he felt his cock head slide through into Kelsey's inner sanctuary. He heard her gasp and felt her tense up as he violated her. His ribbed xenomorph cock slowly began to push deeper into the hole it craved.

Kelsey felt the ribbed head stimulate her vaginal walls far more than anything had managed before. The head alone was stretching her pussy far more than any man or toy she'd experienced. Despite her best efforts, moans began to escape her lips. She knew a cock this size should be tearing her apart, but it wasn't. Her snatch felt stretched but it wasn't uncomfortable -- in fact it was the opposite. Kelsey knew that this alien phallus could well make her cum, even before it was lodged fully within here.

"Oh fuck!" Kelsey exclaimed when the ridge tried to push its way into her. She felt so stuffed but it also felt so amazing. Her pussy lips were literally dripping with her juices, mixed with pale green alien pre-cum. An orgasm was starting to build, no doubt about it. The ribbed head felt heavenly as it rubbed against her G-Spot and every nerve around her sex felt like it'd been dialled up to eleven.

Then the ridge made it through, causing Kelsey's first orgasm to explode from her stretched snatch, forcing her eyes to shut and her toes to curl. Her rational brain became overwhelmed, instead letting her corrupted thoughts run riot.

"Yes, yes, yes! Fuck me!" Between the mind and body altering pre-cum and the intense euphoria she was feeling, Kelsey's brain started to be rewired. She was to become a breeder for the xenomorphs. It would be her job to produce fertilised eggs which would in turn infect more alpha human males, transforming them as Darrell had been.

That idea alone was enough to propel Kelsey into the throes of a second climax immediately after the first ended. It was mentally and physically beyond anything she'd ever experienced before. As Darrell's increasingly girthy shaft stretched her, Kelsey's G-Spot exploded, causing her to squirt hot juices out on the forest floor.

"God yes, make me a breeder for your race!" She thought to herself although only screams of pleasure came from her mouth.

Meanwhile, Darrell's pre-cum was having other effects on her body in order to ensure Kelsey could handle becoming a breeder. Her relatively slim frame began to fill out being thicker with her hips expanding to be able to hold and give birth to multiple eggs. Her internal organs were all slowly being altered in ways that were incomprehensible to Kelsey -- the bottom line is that she her health and lifespan, barring foul play, would be far superior to any non-hybridised human.

While Kelsey had always took pride in her impressive rack -- her 34DDs had always got her ample male and female attention -- she secretly wished that her ass was bigger. Now she was about to get her wish: Kelsey's pale butt cheeks began expanding even as Darrell's alien cock continued to slide ever deeper into her pussy. She could feel her new asset jiggling as she was pounded adding to her lust. However, the changes didn't stop there as her boobs also increased, swelling from DDs to 36H. Yet despite their hefty size, there was barely any sag. If Kelsey could have seen herself, she'd have been in heaven, especially as her face also became marginally prettier.

Instead it was Rob who saw these changes. Initially he thought it was his brain playing tricks on him, but it quickly became clear that Kelsey had become ever hotter, complete with a cracking hourglass figure. Shamefully, he felt his own penis start to get erect at the sight of his former conquest being fucked and altered by the xenomorph. Indeed, watching her new, bigger arse wobbling as she was pounded was an enticing sight.

Many of Kelsey's changes had already happened internally -- her vagina and body as a whole could now comfortably accommodate giant cocks and sustain any eggs implanted in her. Her human reproductive system had been totally hijacked. In order to encourage regular breeding, the xenomorph pre-cum had increased the size and sensitivity of Kelsey's clit and G-spot, as well as enhancing her vagina's nerves in general.

These changes were what helped Kelsey to her third orgasm, which was the most powerful she'd ever felt by a considerable margin. She felt like her entire body was convulsing with pure pleasure.

Darrell's xenomorph brain told him that his transformation of the human female was complete -- she was now ready for his seed. He picked up his thrusts as every inch of his black cock penetrated Kelsey's soaked snatch. He could feel her hot juices squirting onto him. What was left of his human consciousness was completely turned on by this; sex had never felt so good for him. His alien phallus gave him far more pleasure and was far more powerful than he could ever have hoped far.

Despite all his changes, the tingling feeling that precedes an orgasm felt very familiar. His smooth, black, xenomorph balls were the size of grapefruit and Darrell knew that the cum contained within would mix with Kelsey's new womb to create new alien life.

While Kelsey continued experiencing wave after wave of climaxes, her hole clamped down on the his alien cock. With an almighty roar, Darrell came. Copious amounts of green, xenomorph spunk ejaculated into the female's altered pussy. Her belly started to expand as it filled her up.

"Ohhhh God yes! Fill me up with all your hot cum! Kelsey shouted between her moans. Her brain was truly lost in pleasure and, through the Hive mind, she understood what an honour being bred was. She blacked out due to the overwhelming pleasure when Darrell's foot long cock fully buried itself into her.

Darrell could feel every shot of cum ejaculating from his cock. It felt amazing, both physically and mentally to know that he was going to be responsible for the alien colonisation of Earth. Kelsey's pussy was just the start. He still had another one of her holes to transform into to a new breeding chamber.

Rob was painfully turned on. And he was feeling guilty as fuck because of it. Part of him knew it was pheromones in the air being released by the pair in front of him. But he also knew that watching Kelsey feel wave after wave of explosive, squirting orgasms would have turned him on regardless. He felt very envious -- although he had to admit that he was feeling more jealous of Kelsey's pleasure than of Darrell's cock.

What is wrong with me? Rob mused.

He was still trapped and had a side view of the action, which had now subsided. Kelsey was barely conscious -- her body sagged forward. The fact that Darrell was supporting her huge arse with his clawed hands was the only thing keeping her semi-upright. Rob had a great view of her hanging tits. They were by far the biggest he'd ever seen in reality and he really wanted to get his hands on them. He was so distracted by them that he missed seeing her hanging belly at first.

Crikey, it looks like she's several months pregnant!

But Darrell wasn't done.

Rob saw him pull his monster cock out, covered in a mixture of his own cum and Kelsey's juices. There was no doubt that her pussy now produced thicker and creamier lube than it had previously. Darrell then aimed his huge, alien pole at Kelsey's tight butt hole. Surely it'd split her in two?

Kelsey was still in a daze. Subconsciously she knew that she was pregnant with an alien egg and that her body had been radically changed to help her produce many more. Consciously, all she could think about was cock despite, or perhaps because, she'd just been fucked better than anyone in history. A feeling of disappointment had filled her when Darrell withdrew.

Darrell lined the tip of his cock up against her asshole. Both his human and alien brain signals commanded him to do one thing -- fuck the female's tight ass and impregnate it. He knew that he'd enjoy this. Very few girls had let his big cock near their asses when he'd been human. It was almost humorous that his even bigger cock would have Kelsey begging him to fuck her very shortly.

The feeling of a cock prodding her backdoor wasn't particularly unfamiliar to Kelsey. Several guys, including Rob had fucked her butt. None had been anywhere close to the size of the xenomorph dick that was currently teasing her rosebud. She knew that she ought to be concerned that the monster pole would tear her apart, but she knew that her modified body would handle it. Kelsey also had to admit to herself that getting torn apart was worth it to experience another climax like those she'd just had.

"Please, fuck my ass with your monster cock!" Rob couldn't believe his ears when he heard that yell come from Kelsey's mouth. What the devil had Darrell done to her?

Kelsey began to whimper as Darrell's long, alien fingers scooped some of her thick juices from her pussy and rubbed it onto her smooth, pink asshole. She really wanted to have her backdoor bred and she was acting like a bitch in heat. She pushed her plump butt back onto the thick black phallus. A gasp escaped her red lips as she felt the oversized tip force itself past her outer ring. An instant mixture of pain and pleasure rushed to her brain, overwhelming all other signals, causing her to go lightheaded.

Darrell's enhanced senses could practically hear and feel Kelsey's heart pounding as his invader slipped into her ass. He'd never felt tightness like it and he already knew that his alien cock wouldn't last long. He pushed forward, sliding several more inches into the her hole. The sight of her pale skin accepting his midnight black dick was an immensely powerful turn on for the human remnants of his brain. The walls of Kelsey's rectum felt like his own personal cock sleeve. Further in he went -- his cock's ridge needed extra effort to get it through her abused sphincter which caused a further assault on Kelsey's nervous system, setting off her first anal orgasm.

Kelsey's mind was now totally warped and overwhelmed by pure joy. She'd always enjoyed anal but wouldn't have called it as pleasurable as vaginal sex on the whole. However, this anal sex was totally amazing and if hadn't even fully began. The giant dick in her was stretching her beyond any limits she'd assumed she'd had. The pre-cum was once again having an effect on her anatomy, elasticising her butt hole and rectum to the point where it could take such a large intruder, not to mention carry an egg. Her asshole fully convulsed on Darrell's dick, pulling him further in. Kelsey also felt her abused pussy ejaculate more juices out of her hole as she struggled to stop herself from blacking out again due to the sheer pleasure.

Darrell's cock was now over half way in. He began to thrust, knowing that her tightness was going to make him cum before he managed to totally impale Kelsey's ass. The human part of his brain was disappointed by that, but he knew that he'd have many more chances in the future to be balls deep in her backdoor. And he still had another ass to fuck tonight!

The ribbed head of Darrell's cock was once again driving Kelsey crazy with pleasure. Her butt had never felt so full -- even though only 8 inches were in her, the girth was also far bigger than anything she'd ever experienced. For the first time tonight, her fingers felt her newly enlarged clit. Even just brushing against it caused her to go weak at the knees, although Darrell's claws were keeping her from going anywhere.

This body is amazing! Kelsey thought to herself, as she began to rub her clit. She mentally licked her lips with anticipation -- this orgasm was going to feel amazing, and she was on the verge of it due to alien cock.

Darrell knew that he was only seconds away from filling up Kelsey's rectum with his seed. Her butt hole was twitching around his dick as she reached another climax -- this one wasn't so much one orgasm but a wave of multiple ones, all mixing together. It pushed Darrell over the edge and for the second time tonight, he unleashed a huge amount of hot, green cum into Kelsey. There was so much of it that her ass couldn't keep it all in -- green cum began leaking out of her stretched hole where it joined Kelsey's pussy juices as she experienced wave after wave of squirting orgasms. The forest floor beneath her holes was utterly soaked.

Darrell pulled his xenomorph dick out of her gaping ass. Green cum continued to ooze out. Her rectum now contained an egg, identical to the one in her vagina. Kelsey's digestive system had been totally rewritten -- her hybrid body now required xenomorph cum alone to survive and she would produce no waste. The eggs would absorb the nutrition they needed from her. Darrell helped Kelsey to the floor; she was so spent that she couldn't stand without his aid. Her belly now looked close to 9 months pregnant, although her skin was flawless due to the effects of the hybridisation.

Rob would never have admitted that he'd enjoyed the show -- he repeated tried to tell himself he hadn't, even as his uncomfortably hard cock leaked pre-cum into his underwear. But the sight of Darrell's praying mantis like alien form turning towards him was enough to shrink his erection almost instantly. The clawed hand reached out towards him and Rob braced for the worst...

End of Part One.
