Test Subject
By Droid447

Aylin analyzed every electric circuit but she couldn't find the glitch that was keeping her spacecraft from reaching hyper speed. Her fuel pods were running on empty and there were no space ports close enough to provide shelter.

Lucky for her, a small dot showed up on her long range scanner and she adjusted the curse accordingly. When she got closer to the coordinates, Aylin was astounded. It was a derelict cruiser, and there was nothing small about it.

Wow! That thing is huge. Looks like there is no activity inside. I wonder who built it. she thought, In any case, I have no choice but to land. Maybe I can recharge fuel and find something to fix the electrical problem of this crappy ship.

Even though the ship seemed abandoned, it was still functional. The doors of the landing port opened when she approached and closed behind her when the spacecraft descended. When her instruments detected breathable air inside of the ship. Aylin couldn't believe it. It must have been built by humans hundreds of years ago, which meant there could be spare parts for her to use. Her luck was changing for the better.

Aylin stepped out and looked around. The cruiser was in perfect shape. She wondered why the crew had abandoned it.

Suddenly, with the corner of her eye, Aylin saw movement. She turned her head to see a robot walking towards her in a hurried pace. It had a menacing appearance and Aylin reached for her gun. She cursed when she realized that she had left it in the cockpit.

“Fuck! That thing is coming this way! Crap! My gun! I left it in my seat!

Aylin could hear the robot saying something but not to her...”Log 371X – Possible test subject arriving.”

The humanoid robot slowed down and stopped one meter away from the nervous woman. He spoke in perfect English and didn't seem to be aggressive. All good news.

“Are you the test subject? You are 1,492 days late,” the robot said.

“What are you taking about? Who owns this place?” Aylin responded with another question.

“Master built this place to make invaluable research. He has not return in 1,489 days. I am in charge of the latest experiment. Are you the test subject?” the robot ask again.

“The hell I am. My ship has electrical problems and I need assistance. Can you fix it?” Aylin said, hoping that the robot could help.

“If you are the test subject, I can fix your ship. If you are not, you have to leave right now,” the robot responded.

“I can't leave with a broken ship, you idiot. Fuck off! I'll fix it myself,” Aylin responded angrily, guessing that this robot was not an artificial intelligence. It was just programmed to do a specific job and was useless to her.

Aylin decided to explore the cruiser. She needed to find something edible first, then find some tools to work on the ship's electrical problem.

***

She searched for many hours without success. Most of the doors were closed and there was no way to override the locks. The voice control of the cruiser was not responding to her commands and the technology used in this place was too sophisticated for her to hack. Aylin remembered that the robot had said that it could fix the ship. She decided to talk to him again.

Aylin found the robot in some kind of laboratory, “You said that you can fix my ship, right?”

“If you are the test subject, I can fix your ship,” the robot responded. He was holding a weird device.

“Test subject for what?” Aylin asked.

“For the next experiment,” the robot said briefly.

“If I agree to do it. Will I be hurt in any way?” Aylin asked, evaluating the situation.

“The test subject will not be damaged,” the robot answered.

“Fine, I'll do it. But you will fix my ship when the experiment is done.”

“Affirmative. Take off your suit and I'll put this device on.”

Aylin didn't mind getting naked; that taboo had been eradicated decades ago. The only purpose of her suit was to protect her from cold temperatures. But she protested when the robot moved the device closer to her bare back. The contraption seemed complex and a little suspicious.

As the robot placed it along her spine, Aylin felt it attaching to her skin. The procedure hurt, but not enough to worry about it.

“What is this gadget for? I feel tiny punctures on my back.”

“It purpose is to increase your endurance,” the robot responded.

“That sounds good. Will I be stronger?” Aylin asked.

“Unknown.”

The robot led Aylin to an adjacent room, which had an isolation chamber. Aylin got a bad feeling about it, but her curiosity had always been stronger that her common sense. That was the reason she became an explorer.

Inside the chamber, Aylin could see three large eggs. There were alien eggs! No way she was going inside. Unfortunately, it was not her choice anymore. When she tried to move away, her legs didn't respond. At that moment, she understood the true purpose of the device attached to her spine. It was controlling her body! Aylin felt panic. The robot had tricked her. By controlling the device, he could control her!

“What the fuck is happening?! I can't move.”

“You will move in a moment. We are taking control.”

“You lying son of a bitch!!”

Aylin could still speak and she could also turn her head. Apparently, the gadget was controlling her body from the neck down. Her legs moved and she walked into the chamber while the door closed behind her. Then she stood still, facing the eggs. The metallic floor felt cold under her feet, which meant that she still had all her senses intact.

The stiff woman gasped when she saw the egg in the middle opening like a flower. An instant later, a creature crawled out from within, standing at the edge of the fleshy shell. The organism scanned the surroundings and quickly detected Aylin's presence.

Shit! The egg is opening! ...what the fuck is that?!

The woman's heart was beating fast inside of her chest and her breathing accelerated. The creature was rather small, and apparently didn't have any teeth or spikes, but it was scary nonetheless.

An instant later, Aylin saw the creature jumping towards her. It had eight bony legs and a long tail.

In her mind, the scare woman was flinching and moving out of the way, but in reality, she was standing like a statue, unable to do anything. She watched with disbelief as the creature flew through the air towards her crotch.

The creature aimed perfectly and landed on her pelvis, quickly wrapping its long legs around her hips and its tail around her right thigh, securing its position.

Aylin was desperately trying to regain control of her arms, so she could push the monster away, but her muscles were not responding. To make things worse, the scared woman felt something pressing at her vaginal entry.

It wants to push something inside of me!!

Then it penetrated her! Some kind of fleshy appendage, long and cold. At first, it went in a few centimeters and wiggled around, exploring her cavity. Then it penetrated deeper. Aylin couldn't believe this was happening to her. She thought she was going to die and was tensely waiting for the creature to rip her guts apart. There was nothing she could do to stop it. Then she realized with astonishment that the monster was being gentle. It penetrated slowly into her body, squirming and twitching, finding the path with less resistance. The coldness of the appendage quickly changed into a pleasant warmth.

Aylin startled herself when she elicited a soft moan as the phallus reached the bottom of her pussy. The surprised woman had never felt anything so deep inside of her. She could swear that the appendage was wiggling inside of her womb, but that was impossible; it felt too pleasant.

The tentacle was expanding and contracting, increasing the joyful sensations. Aylin couldn't know that the purpose of these motions were to push a small egg, which was slowly gliding within the hollow ovipositor.

Then she felt it! The creature's phallus bulged larger inside of her and something came out it. The organism was definitely dropping something in her womb. An egg! Aylin began to understand what was really happening...

“Gods!! This thing is shoving eggs inside of me!”

The creature was fucking her with an ovipositor and now it was pushing eggs into her womb! She wanted to feel disgusted, but she felt only pleasure. Her pussy twitched around the tentacle, showing an unwanted excitement that Aylin couldn't suppress. It was an instinctive action, beyond the control of her conscious mind.

More eggs followed the first one and after a while, Aylin was displaying a slight bulge on her belly. The troubled woman was fighting against those unwanted feelings that spread deliciously from her crotch in every direction, but she was losing the battle. Now her pussy was twitching without pause and each egg expelled into her womb was bringing her closer to orgasm. Somewhere deep within her mind, Aylin wanted it to happen. She needed some release from this burning fire that kept growing in her loins.

At last, Aylin reached climax. She didn't care that it was a monster fucking her pussy. Nor she cared that her womb was being stuffed with alien eggs. At this moment, the entire universe was reduced to the blissful waves of orgasmic pleasure that overshadowed everything else. Aylin hadn't cum so hard in a long time.

It was a weird orgasm nonetheless. Despite feeling incredible pleasure, she was just standing there like a robot. Her arms and legs were trembling timidly and her pussy was twitching over and over, but these reactions would be barely noticeable to an outside observer.

For a fraction of a second, Aylin noticed that the gadget attached to her spine couldn't keep up with the myriad of sensation cluttering her brain, and she could feel as if her motions were her own again. This happened a few times during her climax. Unfortunately, all she could do on those brief instants was to moan loudly and contort spasmodically.

In one of those moments that the device lost control of her body, Aylin's legs caved beneath her and she crumbled to the ground. The creature clutched the woman's hips tighter. It wasn't letting go until it was done with her.

The device let me fall. It lost control of my body for a second!

Aylin felt dizzy after such a mind-blowing orgasm, but she knew that something important had just happened. She had discovered a flaw in the controlling gadget. It didn't work properly during her climax! Aylin had to figure out a way to use this defect to her advantage.

A squishy sound filled the chamber, interrupting Aylin's thoughts. Another egg was opening and a creature, identical to the first one, climbed to the upper rim.

The device, having regained full control of Aylin's body, forced her to kneel on the floor. The agitated woman could feel one more egg being pushed into her womb and her pussy jolted in response. She turned her head and looked at the other creature, ready to jump towards her, and her pussy twitched again.

“Gods! How many eggs will I have inside of me when this is over?!”

She wondered what was going to happen. Will the two creatures fight for access to her pussy? Will the new creature wait until the other one was done? Then Aylin thought of another possibility and her heart skipped a beat.

And she was right about her suspicion. The other creature jumped and attached itself to her buttocks. There would be no competition for her pussy, since there were other cavities available.

“It is going to fuck my ass!!”

Conflicting feelings roamed in Aylin's mind. She was scared, but also very aroused. It was all so confusing.

As anticipated, the immobile woman felt the second ovipositor poking at her anal entrance, and then piercing through. Aylin was expecting a searing pain, but when she opened her mouth to scream, only a moan of pleasure came out.

The squirming appendage was well lubricated and it penetrated slowly, the same way the first one did, pushing one centimeter at a time and reaching deep inside of her.

Aylin's initial fear quickly vanished and soon there was only arousal. She was being fucked in both holes simultaneously for the first time in her life. Aylin was fully aware that the appendages churning within her body were alien, but it didn't make them less pleasurable.

The creature's cocks expanded and contracted over and over, driving the woman insane, until she couldn't resist any longer and exploded in climax on more time. Aylin was really surprised of having another orgasm so fast, but she wasn't complaining. This climax was even stronger than the first one. Her eyes rolled back and her entire body shuddered violently from head to toe, however the latter was only happening in her mind. Aylin remained in place, kneeling rigidly with her arms limp by her sides.

The same way as before, the device couldn't keep up with Aylin's mind-blowing orgasmic signals and lost control of her body for brief instants, during which the woman's hands jerked and contorted, showing the proper response to such a powerful climax.

As her bliss faded away, Aylin felt the new ovipositor also pushing something into her insides and her pussy gushed in response. There were already several eggs in her womb and soon there would be just as many in her ass.

The other one is pushing eggs inside of me too!

Aylin realized something else; despite her orgasm, she still felt very horny and her arousal was on the rise again. She wondered if the contraption attached to her back was not only controlling her body but also influencing her mind, making her crave alien cocks.

Outside the chamber, the robot was watching every detail of the ravaging. “Two organisms in position and placing eggs. One pending,” he said to nobody in particular.

According to his observations, the test subject was responding well to the controlling device, with the exception of brief instants. Having no data on human orgasms, the robot couldn't understand why this was happening, but these moments were too short to be a problem and it dismissed them as irrelevant.

It didn't take long before Aylin reached her third climax. Her mind went blank from utter bliss, causing the device to lose control and letting her fall backwards. The device got smashed against the metallic floor, but unfortunately for Aylin, the blow didn't cause any damage.

However, the woman's hips never touched the ground. She kept them up in the air, allowing the probing organisms to do their job without interruptions.

The last creature had already jumped off the large egg and now was crawling rapidly towards Aylin. It detected that two other creatures were already penetrating the host and there was only one opening available.

Aylin recovered from her climax and she regained focus just in time to see a shadowy figure covering her entire face. Her scream was muted by the bulky body of the organism as it wrapped her bony legs around her skull and its tail around her neck. The woman's heart jolted when she felt the creature's appendage poking at her lips.

However, this time she wasn't at the mercy of the robot because she had control of her head, and more importantly, her mouth. She tightened her lips as hard as she could.

But after a few seconds, Aylin realized that she wasn't able to breathe. Even if she opened her mouth, it was blocked by the organism. She wondered if she was going to choke to dead? Will she die while being stuffed with eggs and double penetrated by alien creatures? Maybe this was her purpose in this strange experiment; to serve as decaying food for the hatching monsters.

Aylin began to panic and she opened her mouth in desperation. Fresh air filled her lungs and the same time, a new appendage filled her mouth. It squirmed hastily beyond her throat. The woman's body was hypersensitive from the lack of air and the ovipositors in her pussy and ass became more evident as they churned and pulsated.

Aylin exhaled and breathed in again. The creature was feeding her oxigen! She was surprised, confused and excited. The appendage in her throat began to pulsate as well and the aroused woman felt one egg passing between her lips and slide downwards through her gullet and into her belly. She exploded in climax once again.

***

A while later, Aylin opened her eyes and found herself alone on the floor, She had passed out some time during the ravaging. Aylin had partial control of her arms and legs but lost it quickly. As soon as she was fully conscious, the contraption took over.

I came so hard that I passed out.

She noticed that the three organisms that had fucked her were now lying inert around the floor. The long ovipositors had partially retracted into the creatures' bodies but were mostly exposed, also motionless. Aylin assumed that they were dead. They had served their purpose.

Aylin could feel a bloatedness in her belly caused by the eggs. She stared at the ceiling, wondering what was going to happen next.

The answer came quickly. Like a passenger in her own body, Aylin stood up, walked out of the chamber and stepped into an adjacent room that contained an identical enclosure. As she got closer, she saw an ugly humanoid standing inside. Aylin had seen this species before and her heart jolted with fear. She knew they were extremely dangerous and wondered if the robot was aware of that. If he made her walk into the chamber, she was dead for sure. Then she heard his synthetic voice…

“Enter the chamber.”

“Holy crap! That's a yautja! Don't make me go in there.”

The robot was right behind her, moving her like a puppet. He stopped near the window and forced her to approach the door.

The yautjas were smart, crafty and vicious. Aylin was thinking that even fully armed, it was unlikely that she would defeat him in battle. Today she was completely naked, walking helplessly to the slaughter.

The creature saw her stepping in. He waited in a fighting stance while extracting his wrist blades, ready to kill.

But Aylin quickly noticed something completely out of place. The yautja's phallus was unprotected and dangling freely between his legs. There could be only one reason for him to be nude like this. He was also under the robot's control.

As she walked closer to him, the yautja went rigid and stood immobile. His wrist blades retracted. Aylin leaned forward, grabbed his phallus and began stimulating him. The woman moved gracefully but she was not in control of her arms and legs. At least she knew that she wasn't going to die right away. The robot most certainly was planning something else.

The astounded woman watched the creature's cock grow between her fingers. It felt a bit firmer than a human cock, but the size was pretty much the same of a well-endowed man.

I can't believe that I am giving a hand-job to a yautja.

She heard him making weird noises with his mouth and she figured that he could also move his head at will, but not the rest of his body. Although, the yautja's cock was responding as expected to the involuntary massaging and it grew even bigger until it was fully erect.

Aylin got anxious, guessing that very soon that phallus was going to be penetrating her pussy. Why else would the robot put her in the same room with this monster?

And her fears were completely justified. The robot made her bend over, supporting her weight on a metallic box, while the yautja moved behind her. He was going to fuck her with that big, green cock and there was nothing she could do to prevent it.

For the Gods! He is going to fuck me! His cock is huge!

Then she thought about the eggs inside of her. Most likely, this monster was going to ejaculate in her pussy and flood her womb. Was this the experiment? The robot wanted to use her body as a petri dish to fertilize alien eggs? This was insane!

Aylin gasped when she felt the tip of his phallus touching her pussy lips. Then it moved forward, brutally stretching her vaginal entrance until the cock head was inside. Aylin shrieked. The girth was three times fatter than the ovipositor's.

More of the phallus pierced in and she screamed again. This was definitely the biggest cock she had fucked in her entire life. When it was half way in, the creature pulled back, and then in again, a couple of centimeters deeper. He did this a few times until the tip was banging against her uterus.

He is so freaking big!

The yautja was trying with all his might to fight against the controlling device on his back. He was angry and frustrated. He could see that the intruder had a similar contraption on her back, which meant that she was here against her will.

But then he realized something else. The human's pussy was clenching his cock in the most pleasant way. He had only mated with females of his own species and this experience was new to him. This female was warmer and softer.

After a moment, the odd couple was getting a rhythm. They fucked with stiff, perfect motions that made them look like machines. Aylin was almost standing, with her knees and torso slightly bent forward. She moved her hips backward in perfect synchrony with the cock that moved in the opposite direction.

The yautja had his feet steady on the ground while he swayed his hips back and forth, penetrating the tight pussy in front of him all the way to the bottom. He wasn't so angry anymore. If he wasn't under control of the device, this female would be dead right now and he wouldn't be enjoying the strange mating session.

Every time his cock reached the bottom of the Aylin's pussy, the yautja groaned with pleasure.

He had been so stupid for letting himself get captured, but at least something good was coming out of this nightmare. He had learned that human females were great for fucking.

Both Aylin and the yautja felt their excitement rising to a boiling point. As he got randier, he wanted to fuck her faster and deeper, but the device wouldn't allow it. He kept moving with the same pace. Only his grunts got louder.

If we keep this up for a little longer, I am going to cum again! Aylin thought.

Aylin was on the verge of climax and she wanted that cock to pump her as fast as possible. The same way it happened with the ovipositors, she didn't care anymore that it was an alien cock lodged in her pussy. All she wanted was release...

The both reached climax at the same time. Aylin felt the first gush of hot sperm ejaculating within her loins and she exploded in mind-blowing bliss. Apparently, the device controlling the yautja had the same flaw, because she felt his hands grabbing her waist, pulling her closer to his body and lifting her off the ground.

Aylin didn't think it was possible, but when he pulled her back, his cock went even deeper. Her eyes rolled until they were mostly white, her legs shivered violently and her pussy twitched over and over, milking the creature's balls to the last drop.

This orgasm was stronger than any of the ones she enjoyed in the other chamber. Aylin could feel the device losing control of her body for longer periods of time, but all she could do was shiver in utter pleasure.

It was obvious that the yautja was experiencing the same thing, because he kept his tight grip around her waist. The device wasn't controlling him at this moment. But it didn't seem to matter. The creature was acting by instinct and his only desire was to push his cock as deep as possible into Aylin's body and ejaculate inside of her.

Aylin could imagine the multiple eggs in her womb getting bathed with sperm, being fertilize one by one. Her orgasm was fading away but she could feel her partner's cock still pulsating, spewing cum within her body. It felt so good. No human male could ejaculate this much.

When his orgasm was over, the yautja let go of Aylin and she fell to ground. The device took over again.

Aylin thought about the experiment in which she was an unwilling participant. Now some of the eggs in her body were inundated with cum, but evidently these eggs came from a different species than the yautja's. It was unlikely that the his sperm would be able to fertilize them. Maybe the stupid robot had it wrong and nothing was going to happen after all.

I hope these eggs die inside of me and then I'll just push them out.

In any case, she could feel her body moving on its own again and she knew that the ordeal was not over. The robot made her lay on her stomach and she saw the creature looming on top of her. After a few seconds, his cock was poking at her anal entrance. Aylin didn't know how to feel about this.

He is going to fuck my ass!! I wonder if this will make me cum too.

The aroused woman felt the fat cock penetrating her ass and moaned loudly. The previous sex session had felt so good. There was no reason to believe that this would be different.

After a moment, they got into rhythm. Mechanical movements with perfect synchronization. Now Aylin was certain that she was going to climax again soon enough and she couldn't wait for it.

For the gods! This feels awesome! I wonder why I had never tried it before.

This session lasted longer, but the end result was the same. Both Aylin and the yautja exploded in orgasm simultaneously. The eggs lodged in Aylin's ass were flooded with sperm too, but the woman wasn't worried anymore. She didn't know for sure that her incompatibility theory was accurate, however, the pleasure she felt at this moment was too great to care about little details.

One thing Aylin couldn't understand was how the yautja could store so much sperm in his balls. She could feel his phallus pulsating over and over, ejaculating buckets of cum into her loins. This sensation pushed her orgasm beyond the limits of comprehension. Aylin thought she was going insane.

The robot knew that he only had control of Aylin from the neck down, so he needed to figure out a way to make her suck the male's phallus and swallow his cum, in order to fertilize the eggs in her belly. He had an idea to accomplish this.

He made the couple fuck again. The yautja was kneeling with his torso tilted backwards and Aylin was sitting on his lap, with his cock buried deeply in her pussy. He moved his crotch forward and backward while she waved her hips the same way. The sensation was delightful for both of them.

The odd couple was now fucking while facing each other. Aylin still thought that he was ugly as hell, but his cock was a gift from heaven. She swayed her hips sensually while looking at his yellowish eyes. It was so pleasurable that, maybe if she wasn't under the control of the device, she would be doing the same thing by her own accord.

The yautja stared at the woman's face with curiosity. She looked back at him, but from time to time, her eyes rolled up her head. He suspected that this was a primal reaction to the sensations of the mating session. She was enjoying this as much as he was.

While she looked at his monstrous face, Aylin realized that there wasn't hate in his eyes anymore. He despised being controlled by the robot the same way she did, but he didn't hate her. They both were part of this experiment against their will, and despite the circumstances, their sexual compatibility was more than evident.

Aylin kept looking at his eyes, avoiding the rest of his face, getting some comfort in the knowledge that she was not alone in this odyssey.

The couple went through the motions for a while until they climaxed yet again. Aylin threw her head back and screamed in bliss while he squirted his cum inside of her pussy. She couldn't understand why the robot was flooding the eggs in her womb one more time, but she didn't care.

Despite her orgasm, the controlling contraption kept her moving her hips as fast as possible, only interrupted for brief moments. The yautja kept swaying his crotch as well, stabbing her pussy while filling it with sperm.

This quickly became Aylin's strongest orgasm so far. The stimulation was so overwhelming that she started to lose consciousness. Aylin tried very hard to enjoy this bliss for as long as possible, but at the end, she lost the battle. When the orgasm was over, Aylin was unconscious. She had her back resting on the floor and her hips on her partner's thighs. Her eyes were partially open, showing only white.

The yautja's phallus slipped out of her pussy and amazingly it was still erect. He looked down at the female, wondering if she was dead. He noticed that she was breathing and he felt some kind of relief. He was hoping that he could fuck her again later on.

The yautja soon found himself moving, following the robot's commands. He lifted Aylin's unconscious body and placed her on top of a crate. Her legs hung from one end and her head and arms from the other. Then the yautja pressed his erect cock against the woman's lips and this brought her back to consciousness. Aylin was confused. She could see the creature's long phallus upside down, right in front of her face.

“What… is going on?” She asked groggily, but quickly understood what was happening. Her partner wanted a blowjob.

Aylin willingly opened her mouth and let him in. The phallus immediately reached the back of her throat and penetrated further down her esophagus. The woman's pussy twitched hard as she felt the thick cock stretching her lips, then her neck. She was staring at her partner's balls, hanging a few centimeters from her face and getting closer. This meant that most of his phallus was already buried down her throat and more was coming! Aylin's pussy twitched again.

The yautja was amazed that he could fuck this woman's face so deeply. He could never do that with a female of his own species since their mouths were not able to stretch that much. This slim human was full of pleasant surprises.

He started fucking the woman's throat with a rhythmic pattern, moving his crotch back and forth, allowing her to breathe a couple of times every minute. Aylin was so aroused, that a small puddle of her own lubricating fluids was growing between her thighs.

Squelching sounds bounced against the glass walls of the chamber and made the whole ambiance even more erotic. The yautja wanted to fuck Aylin's mouth faster, but the robot didn't know or cared about what he wanted. They maintained a steady rhythm, getting slowly but certainly closer to orgasm.

Aylin couldn't believe it was possible to reach climax just by having a big cock in her mouth, but her pussy was burning with excitement and it twitched in synchrony with her partner's motions. Her muffled moans and his groans got louder. They were going to cum again very soon…

He shoved his cock one last time and then he discharged a huge load of sperm directly into her belly!

Aylin felt his phallus throbbing between her lips, then she felt the warmth of his sperm flowing within her loins. She exploded in climax too. The first few seconds of orgasmic turmoil only happened in Aylin's mind, preventing her to think about anything but utter bliss while the rest of her body remained motionless.

Then the device lost control of Aylin's neuronal signals and she responded accordingly to the waves of mind-blowing pleasure that radiated from her core. The woman's left leg stretched out and trembled rapidly while her pussy jolted so hard, that a stream of her lubrication fluid gushed forcefully across the air.

When the yautja was done ejaculating, he stepped back, removing his phallus from the woman's oral cavity. The creature would have preferred to remain a little longer with his cock between her lips, enjoying her tightness and her warmth, but he was not the one in control.

Aylin was still climaxing while he pulled away and the powerful orgasmic contractions forced some of the accumulated sperm to erupt from her mouth like a fountain.

She still couldn't believe that it was possible to cum this hard just by giving a blowjob and without touching her body, but here she was, shuddering in bliss and relishing every second of it. At least, the weird experience was showing her something new about herself.

A moment later, all was quiet again. Aylin was catching her breath with remnants of cum gliding down her face, staring into nothing with half opened eyes. She was thinking about the huge amount of sperm churning in her belly at this moment. The eggs that she swallowed earlier should be swimming in it. She better be right about the incompatibility of these two species.

I hope I am right about the eggs… I am stuffed with cum.

As her orgasmic brainwaves faded away, the contraption took over. The robot made Aylin stand up and guided her towards the door. The experiment in this chamber had been completed.

The yautja watched her go with a hint of sadness. He had been in this cell for a long time and he didn't know how much longer he will remain trapped in this place. This human female could help him pass the time while he think on a way to escape.

Aylin turned her head as she walked, looking back at the ugly humanoid. She knew that he was in the exact same situation as hers, and this made her feel less alone in this ordeal. She felt sorry that the robot was taking her away from him.

“I wish I could stay here,” she said, not certain that he could understand her.

In the back of her mind, Aylin also felt sorry to leave behind his gorgeous cock, but she pretended she didn't care about it.

****

There was another adjacent room with another chamber inside. Aylin was more curious than scared about what was waiting for her this time, but than changed the instant she passed through the door…

There was a xenomorph inside! These were savage monsters with the single purpose of killing whatever crossed their path to feed their queen. Aylin tried with all her might to run out of there but her body didn't respond and the robot made her walk straight to the creature.

“Gods! Take me out of here!!”

The xenomorph had been curled up in a corner of the chamber. The moment Aylin entered, it started moving and showing its teeth.

When Aylin reached the center of the room, the xenomorph jumped with amazing speed and tackled her to the ground. His face, filled with sharp teeth, was a few centimeters from hers and the terrified woman believed she was going to die for sure. She had never been more scared in her entire life.

But then she noticed some hesitation from the creature. She couldn't see any device attached to his back but maybe the robot was also controlling him somehow. Aylin considered the possibility that she might survive this too, the same way she did with the yautja.

Trembling with fear, she saw the monster's head moving down her body. He stopped a second at her breasts, smelling them, then moved further down, stopping again at her belly. He placed his eyeless face right above her abdomen and examined her carefully.

The eggs!!! It is smelling eggs!

It was then when Aylin remembered that her body was stuffed with alien eggs. The xenomorph had detected them and this was the only reason why she wasn't dead yet. She was carrying his queen's offspring.

The creature moved back and stood on two legs. The robot made Aylin sat up and the woman's eyes were immediately drawn towards his crotch. A large, shinny cock had emerged from his body and now was dangling between his legs, getting even bigger.

“His cock is out!” Aylin said, realizing what was going to happen next. This monster was going to fuck her!

After all that had happened to her so far, she wasn't sure if this was a bad thing. Getting ravaged meant staying alive. A moment later, Aylin was standing and bending over, offering her ass to the xenomorph.

Oddly enough, the creature knew exactly what to do, as if he had done this before. He grabbed Aylin's hips and aimed his phallus at the woman's vaginal entrance.

I can't believe a xenomorph is going to fuck me. Not in a million years I thought this could ever happen.

Aylin felt his cock touching her pussy lips and gasped. She looked back noticing that his phallus was thicker and longer than the yautja's. She wondered if it was going to hurt this time, but she doubted it.

The astounded woman screamed when she felt the enormous phallus penetrating her as deep as humanly possible. The xenomorph's motions were not slow and robotic like the yautja's. This monster was brutal and started fucking her in a frenetic way. Aylin could feel the malleable eggs within her womb being pushed apart to make room for the large cock that relentlessly invaded her body.

While taking in such a huge appendage, Aylin felt a brief moment of discomfort and then a burst of incredible pleasure. Now she wondered if she was going insane. How could she enjoy so much this brutal ravaging from different ugly monsters?

She had never felt any attraction towards alien's in the past. Nor she had any sexual experience with one. But now she was beginning to understand why there were groups of women that didn't bother to have sex with human males any more. She didn't know if she would be able to have normal sex after this.

The xenomorph had smelled a large amount of eggs inside this warm host and he was desperate to fertilize all of them. It would be a huge triumph to be the father of the queen's offspring. He had been taken away from his queen and kept in this closed space for too long. This compensated all of it.

Despite the fast pace of his motions, the xenomorph took several minutes to reach his peak. During this time, Aylin climaxed two times and she was in the midst of her third orgasm. The sheer size of the monster's cock was enough to send her over the edge with ease, but adding the frantic speed of his thrusts was more than she could take.

This monster was not only a ruthless killer; he was also a sex machine. His objective was clear and he wanted to complete it as quickly as possible to avoid possible interruptions. The creature couldn't know that the robot was making sure if having no interference with the fertilization process. He was allowed to fuck Aylin for as long as he wanted.

Then, after twenty minutes of brutal hammering, the xenomorph ejaculated inside Aylin's womb. As expected, the sensation of warm sperm filling her loins reignited Aylin's climax, transporting her to new heights of pleasure.

****

Aylin's head was spinning. She was lying limply on the floor, her eyes still rolled back into her skull, and shuddering sporadically from her receding orgasm. At this moment, within the haziness of utter bliss, she was in full control of her body but was too overwhelmed to the anything.

Meanwhile, the xenomorph was kneeling beside her with his head very close to her buttocks. He was smelling the eggs inside of her body and realized that not all of them had been bathed with his sperm. Some of the eggs were kept in different cavities. This host was more complex than he thought.

Analyzing her body more closely, the monster discovered that there was another opening on the woman's lower section.

Before the creature figured out what to do, Aylin slowly stood up, walked over to a nearby crate and laid on top, facing upwards. Then she pulled her legs up to her chest, offering a full view of her anus to the watching monster.

The xenomorph couldn't understand why this female was cooperating but the didn't care. He wasn't wasting this opportunity to fuck her in the ass, and consequently, fertilizing the rest of the eggs.

At this moment, Aylin had a frightening thought. She considered the possibility that, unlike the yautja's, this creature's semen would be compatible with the eggs churning in her body.

If this monster's sperm is compatible with the eggs, I am screwed!

It was a dreadful idea, but despite it all, Aylin wanted that cock inside of her again. And her wish was coming true soon enough. The xenomorph moved forward and aimed his cock at the woman's hole. The opening seemed too small compared to the one he just fucked, but there were unfertilized eggs inside of the host and he had to get it in, one way or the other. Aylin was holding her breath; she was ready.

Once again, the penetration was brutal. The large cock pierced into her ass and didn't stop until half a meter of alien meat was buried inside of Aylin's body. The astonished woman felt a combination of pain and pleasure that she had never experienced before. She opened her eyes wide and moaned loudly while her pussy gushed, welcoming the assault.

Aylin felt the enormous cock reaching impossibly deep into her ass. Her pussy twitched once, then twice. On the third time, she exploded in a sudden orgasm. She didn't know that it was possible to cum so fast, but she wasn't complaining. Her eyes rolled back while she rode this new blissful climax. As expected, the controlling device couldn't keep up with her wild brainwaves and the woman's body started shivering spasmodically.

The xenomorph wondered what was happening to the female and tightened his grip to keep her in place. She wasn't going anywhere before he was done.

Aylin's orgasm slowly receded but not entirely. The monster's frantic hammering was keeping her mind in a state of blissful haziness, half awake, half unconscious.

The bewildered woman was rocking back and forth on top of the crate, with her arms limp by her sides and her legs swinging with the motions. It was difficult to form coherent thoughts but Aylin was dimly aware that she had partial control of her body. The abused woman realized that she could use this to her advantage, but it felt so freaking good to be fucked so deeply in the ass that she lost her train of thought.

Having climaxed once already, it was taking longer for the xenomorph to finish the task. He pumped Aylin's body with frenetic eagerness while squishy sounds filled the room and mixed with the woman's moans.

The robot was observing everything from the other side of the glass walls. This part of the experiment had been risky, putting the test subject inside the chamber with a deadly xenomorph not wearing a controlling device. But the monster had reacted as planned. When he detected the eggs inside of the female, his instinct changed from killing to mating.

A moment later, the creature was fucking the bewildered woman even faster. Then he stopped abruptly and stayed immobile for an instant before discharging a vast amount of cum into Aylin's guts. He ejaculated over and over until the woman's belly was bloating with all the sperm accumulating inside.

Aylin woke up from her blissful reverie only to exploded in another full-blown orgasm. She had lost count of how many times she had climaxed in the last few hours. If this craziness were to continue for a while longer, she was definitely going to lose her mind. The problem was that, at this moment, she wanted more of the same… much more.

The monster's sperm spread within Aylin's entrails while the xenomorph continued ejaculating. He was determined to fill every cavity in her body.

Aylin didn't realize what was going on until she felt the warm fluid rushing up from her belly to her throat. In the following orgasmic convulsion, white sperm gushed from her mouth and flew off her face onto the crate's surface.

Then it happened again! Aylin was confused, astonished and incredibly aroused. How could this be happening? She had a massive cock buried in her ass, pumping sperm nonstop and now she was vomiting cum! The only explanation was that her body must be full to the brim with the monster's seed. Knowing this, Aylin responded the only way she could. Her orgasm reignited with twice the strength as before.

When the ravaging was finally over, Aylin was unconscious. Her body rested feebly on the crate while remnants of sperm leaked from her ass and from her mouth.

The xenomorph had pulled back and smelled the eggs inside of her belly; they all had been fertilized. His job was done. Very soon, she was going to give birth to many new males that would serve the queen and increase the power of the colony.

There was only one problem. They were all locked up in this chamber that the host's body would not be enough to feed the newborns into adulthood.

****

As soon as Aylin recovered from her mind-blowing ordeal, the contraption regained control and forced her to sit up on the crate. Aylin looked around and saw the xenomorph behind her, one meter away. She knew that he was not going to attack her again, but it was a scary view nonetheless.

The eggs must be fertilized now! What the hell is going to happen when they hatch?! Damn robot!

The exhausted woman wondered what was going to happen next. Her brain couldn't take another session like the one she just experienced. She would go insane. Aylin was also worried about the eggs. Were they going to hatch inside of her? Will the newborn monsters eat her from the inside out? There were so many questions and uncertainties. She needed a miracle to get out of this experiment alive.

****

The xenomorph watched with satisfaction as Aylin left the chamber. This meant that his babies were free. He didn't know that Aylin was being guided by the robot into another chamber in an adjacent room. The nervous woman quickly looked around trying to find which horrible creature was waiting for her, but she saw nothing. The chamber was empty except for a bed and an incubator. She was very happy that the robot was going to let her rest for a while.

Finally, I will rest. This will give me some time to think about my escape.

The robot deactivated to device and allowed her to move at will inside the chamber. The device had a safeguard that triggered an automatic shutdown of her body if she tried to remove the contraption or if she got close to the door. Aylin learned about this conditions the hard way.

****

Two days later, Aylin was displaying a large pregnant belly. The eggs had hatched a few hours after impregnation and now she could feel the embryos moving inside of her womb, her stomach and her rectum. These motions had driven her into a couple of unwanted orgasms and was embarrassed by it. But this also gave her an idea...

There were two possibilities by which these small creatures would exit her body. One of them was by eating their way through her guts and killing her in the process. She could only hope that this was not the case.

The second possibility was that these monsters were going to vacate her body following the path of less resistance. In other words, through her pussy and through her ass. Then she could take action and end this stupid experiment once and for all.

They are moving so much inside of me. My pussy is dripping wet.

Aylin didn't have to wait long. Her heart jolted when the creatures within her belly became restless, churning and twisting anxiously. Then her pussy twitched when she felt something slithering from her womb into her vaginal cavity.

“God! It is time! The babies are coming out!”

Aylin was excited and happy. The monsters were not going to eat her alive! At least not during the birthing process. But she had to make sure that that didn't happen afterward either, and she had a plan to accomplish this.

The little creature that came out of Aylin's pussy was as ugly as the parent. It looked like a worm, thicker that her forearm, with tiny developing legs. But there was something very particular about its head. The astonished woman noticed immediately that it had some characteristics of the yautja! Was it possible that both male monsters of different species could fertilize a single egg?

What the fuck?! It looks like the yautja!

Aylin couldn't know that the whole purpose of this experiment was to create a brand new species combining the best features of the xenomorphs and the yautjas.

The master scientist of this massive laboratory had discovered that the estrogen secretions of human females had a unique effect on alien eggs, keeping them receptive for multiple sperm donors. The grotesque newborn squirming out of Aylin's pussy was living proof that he was right.

Based on previous experiments, the robot had been programmed to wait one week for the newborns to arrive, but something about the mixture of DNA from both alien species had accelerated the birthing process exponentially. He was not present at this moment and it was perfect for Aylin's plans.

Before the first critter was completely out of her body, the second one was already emerging and expanding the woman's pussy lips to the limit. It felt as good as Aylin was hoping. Her plan was going to work.

“My belly is not getting smaller and two of them have already come out! How many do I have inside of me?!”

Aylin waited until the third monster was half way out of her body and her growing arousal was getting her closer to orgasm. Then she moved into position. She was very conscious about what she was doing and this triggered the controlling device. She quickly lost control of her arms and legs, but she was already in place and didn't have to do anything else. The lowest section of the contraption was interlocked with the upper rail of the metallic bed support.

The creature was squirming faster, trying to free itself from Aylin's constricting pussy. It was driving her to the verge of climax…

When her orgasm arrived, Aylin's body started shuddering spasmodically and there was nothing that she or the device could do to prevent it. As her legs trembled out of control, the woman's whole weight rested on the tip of the device, which started to bend.

Aylin felt sharp prickles on her lower back as a small segment of the contraption detached from her skin. This pain was almost overshadowed by the marvelous pleasure that spread across her entire body, but it was there nonetheless. Aylin knew that her plan was working.

Oblivious of Aylin's actions to free herself from the device, the little monster squirmed and churned between its mother's thighs. He also was trying to get free from the constricting pussy that clutched around its lower body with great force and made the task more difficult.

A couple of minutes later, after her orgasm was over, Aylin was sitting on the floor in an awkward position, with one leg twisted to her side and the other extended in front of her. She knew that something had happened to the device but she didn't know the extent of the damage. She tried moving her arms and legs and succeeded but this didn't tell her much. She had been in control before inside of this room, as long as she didn't try to escape. The definitive test was trying to remove the contraption. When she did, Aylin lost control of her body again, except for her feet. She could move her feet and her head, but nothing else. She had hoped for more but at least it was progress.

Three little monsters had already come out of Aylin's body. One was out of sight, the other two were slithering around, discovering the world. Aylin noticed that the shape of their heads was similar to the xenomorph's and their jaws were similar to the yautja's. They were as ugly as their fathers.

Then Aylin gasped when something wiggled within her pussy. Another creature was trying to get out of her body, but in her current position the floor was blocking the way. She still looked heavily pregnant and needed to facilitate the birthing process. She wanted all of them out as soon as possible.

One more is coming out. I need to move… as soon as I am able to.

Aylin got on her hands and knees and a moment later, new creatures were being born, not only from her pussy but also from her ass. The little monster stretched her anus wider than ever before as the long head and its snake-like body struggled to get out. A couple of centimeters below, an identical creature was doing the same with Aylin's pussy. The sensation was incredible and the overwhelmed woman could feel a new climax already growing within her loins. She had to take advantage of this.

The lower section of the controlling device was clearly bent back and separated from Aylin's skin. The aroused woman looked ahead and noticed that the incubator encase, which was half a meter tall, could aid to further damage the contraption. She just needed to get there without making her intentions too obvious.

If I can hook the device to the edge of the incubator, I would be able to detach a larger section of this damned machine.

Aylin gave birth to a couple more monsters until she was again on the brink of climax, then she stood up and walked closer to the incubator. A new creature was already poking from her pussy and another one was coming down within her rectum. Aylin turned around, focusing on the pleasure she was feeling, trying not to think on her true goal.

She rested her buttocks on the tilted glass of the incubator and glided down until the bent section of the controlling contraption was touching the metallic top of the encase. Then she relaxed her body and waited for her climax to arrive.

Now I just have to make sure that my body falls straight down and not forward.

The little monster was almost all the way out of Aylin's pussy, with only its tail wiggling around the tight cavity and Aylin could feel another one almost poking thought her anus. She was certain that this was going to send her over the edge… but then she felt something else and got startled. She moved her hand to her chest.

Something was rushing up from her belly within her esophagus. Aylin didn't want to believe that this was another monster but it was the only explanation. She remembered that one of the first bony monsters had deposited eggs directly in her stomach.

“Oh Gods! Are they coming out of my mouth too?! This is not possible!”

Aylin felt the emerging monster stretching her neck, then filling her mouth from within. She couldn't scream, she couldn't even breathe, and she began to panic. But her body was not responding the same way as her brain. Her pussy twitched hard as she felt asphyxiated and stretched beyond the limit.

Aylin quickly realized that she need to embrace this. Her mouth was just another hole from which she could get rid of the birthing monsters. She had been on the verge of climax a moment ago and she needed it desperately. Her freedom depended on this. Aylin opened her mouth as wide as she could and tried to relax again.

She was losing consciousness from the lack of oxygen, but at the last second, she was awake enough to feel a powerful climax igniting within her loins. Her eyes completely rolled back and her pussy gushed. The thickest part of the monster had already passed between her lips and now the rest of his body wiggled within her throat, increasing the incredible bliss.

This overwhelming sensation was unreal and Aylin was never going to forget it. She had wondered if she would be able to enjoy normal sex ever again and now she had an answer. Whether she wanted it or not, aliens were part of her sexual future forever.

****

A while later, Aylin was lying unconscious on the floor. A large section of the controlling contraption had broken off and detached from her back. Now it laid between the woman's feet, near the incubator. Her plan had succeeded!

Many small monsters slithered around Aylin, not knowing what to do. She was still giving birth so they couldn't eat her, but there was no way out of this enclosure
