5 Holes deeper than Mariana Trench

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.
