3 Time to try someone big

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.
