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.
