Test Subject

Aylin felt the hot load of cum filling her womb and her body responded the only way possible; she climaxed too.

Her pussy twitched in perfect synchrony with the pulsating cock, as if both were part of a single entity that burst into existence from perfect bliss.

The shock of his first orgasm was too much for the shivering creature and he lost his balance, slipping backwards. But he was not letting go of the female that made him feel this good and he grabbed Aylin's body tightly, pulling her along with him.

A moment later, the other monster was standing alone with his phallus no longer sheltered by the female's warm ass. He didn't like this at all.

The climaxing woman also felt the fat cock sliding out of her body while she was dragged forward. This thrilling sensation intensified her orgasm.

The monster slowed down the fall with his arms and his tail, still enjoying the orgasmic waves that spread from his crotch to every nerve of his body. Aylin ended up on top of him, resting limply on his chest, while her entire body jolted sporadically from her receding climax.

This new breed of monsters was smart like the yautjas and ruthless like the xenomorphs, but their orgasms screwed up their brains twice as much, at least for a couple of minutes. This was a condition that the scientists did not anticipate.

Meanwhile, the other creature approached from behind and grabbed Aylin's hips, once again aiming his phallus at her ass. He wasn't giving her up that easily. He took advantage of the situation and forcefully pulled Aylin's body toward his crotch, shoving his entire phallus back into the woman's ass.

Aylin was mercilessly awakened from her orgasmic reverie and screamed from the wonderful sensation of this renewed assault.

After a few minutes, the creature could feel his orgasm approaching and he increased the pace. Like his brother, he didn't know what was about the happen but he just couldn't stop.

On the contrary, despite the fact that her brain was cluttered with mind-blowing waves of pleasure, Aylin was perfectly aware of what was coming next, and she couldn't wait for it to happen.

Then, as expected, they both climaxed at the same time.

The same way it happened with his brother, the monster lost control of his body and fell backwards in the midst of orgasmic bliss, ending up outspread on the floor with his mother on top of him. This new orgasm became too much for Aylin and she lost consciousness, even though her body still jolted every few seconds as it laid limply over the hard body of her latest lover.

The other creature had recovered from his climax and now he was walking closer to the shivering couple to inspect the situation.

He noticed that his brother's cock was still buried in Aylin's ass, but the woman's pussy was available. The monster looked at it with lust and curiosity, wondering what was that white fluid dripping from the gaping hole. He had no idea that it was his own semen.

Regardless of his lack of knowledge, he was certain of one thing. He wanted to feel another orgasm as soon as possible.

The creature jumped forward, shoving his entire cock into Aylin's pussy once again. The besieged woman moaned softly but didn't move a muscle. At this moment, she was nothing more than a warm, welcoming, sex slave that existed only for the monster's enjoyment. And she was fine with it.

****

Aylin had no idea what had happened during the last few minutes, but when she recovered her consciousness, she was lying on the hard floor with one of the monsters on top of her, pumping her pussy with anxiousness.

The creature didn't like fucking the female on top of his brother and he had pulled her away, placing her on the ground where he could pinned her down and plunge his phallus as deep as he wanted. Aylin was confused but content with her current situation. The monster's cock felt so freaking good.

Very soon, the monster began to get that feeling again of something building within his loins. He knew now that he was going to cum again and accelerated the pace. But then both he and Aylin noticed that the other creature was standing beside them with his cock fully erect. He wanted a piece of the action and he was not waiting any longer.

Here comes the other one... I guess he is going to fuck my ass again.

But Aylin was pinned against the floor and her ass was not available. Both monsters hissed at each other as a prelude of an imminent fight. The males fighting for a female was just nature taking over.

The arriving monster grabbed his brother's torso and pulled him away. Aylin felt the fat, long phallus harshly vacating her pussy and she screamed from the luscious sensation.

Aylin was still horny as hell and she regretted than her sons were fighting each other instead of fucking her two holes at the same time like they did before. The fevered woman sat up with her legs spread wide and watched the show. It was clear that the fight was not to the death, but only to determined who was stronger and faster. However, the main thing that called Aylin's attention were the monster's long cocks waving around as the creatures twisted and jarred.

"Wow! There are really fighting over me."

Then Aylin realized something else, the creatures were not paying any attention to her. This was her chance to escape!

Without thinking twice about it, Aylin stood up and started running away. She looked back the whole time, confirming that the monsters were too busy fighting to notice that she was escaping. The problem was that she didn't know where to go. Aylin was very aware of how many monsters had come out of her body the day before, and all of them were creeping around the vessel. Her chances of fixing her ship and fleeing this place were not good.

"Where the hell should I hide?!"

To make things worse, maybe her next encounter with one of her sons would be less sexual and more of the eating kind. She had to make a plan and she had to do it fast.

Aylin had an idea. It was risky, but it was her best chance. The intrepid woman went back to the yautja. She looked outside of his containment chamber and found one of his weapons. Then she opened the door and walked inside.

The yautja saw her holding his blades. At first he thought that this sexy female was coming to kill him. The controlling device didn't allow any kind of defense and he was as good as dead.

Aylin approached him slowly and she couldn't avoid looking at his dangling cock. Her pussy twitched just thinking about the orgasms she enjoyed riding that phallus.

"I am here to set you free. I am sure we can help each other."

The humanoid heard Aylin saying something but he couldn't understand a word. However, the yautja was smart and when Aylin placed the weapon on his hand, he understood immediately what was going on. This human was helping him escape!

"Let's take this infernal apparatus off you. Just don't kill me when you are free, okay?"

Aylin walked around her new partner and started dislodging the device. The gadget activated its defense mechanism and the yautja couldn't move a muscle, but he didn't have to. Aylin was doing all the work. As soon as he regained control of his body, the yautja started running and Aylin ran behind him. It didn't take long before they crossed paths with one of Aylin's heinous sons.

The monster attacked, but the yautja was ready and he threw his sharp blades, cutting deep into his chest and killing him on the spot.

"Holy crap! That weapon severed his chest!" Aylin knew at that very moment that she had made the right choice. One monster down, several to go.

The yautja was not sure about which way to go. When he hesitated, Aylin led the way. She remembered the path to the hangar, where her broken ship was waiting.

Every time they encountered a monster, Aylin stepped back and the yautja took care of him. He was amazingly good in combat and his blade was deadly as hell. Aylin was very happy that he was on her side, at least for now.

They reached the hangar and Aylin hurried to open the hatch of her ship. Once inside, they would be safe.

"Let's go!! The hatch is open. Come inside!" Aylin yelled.

When the yautja jumped on board, Aylin started the ship and took off into space.

****

It was no surprise that he was skilled enough to fix the electrical malfunction in a few hours. The vessel could achieve hyper speed now.

Without asking for permission, the humanoid reprogrammed the ship's destination to his home planet. Considering that he saved her life, Aylin didn't mind giving him a ride.

"I guess I am giving you a ride home. Just don't forget that this is my ship and we saved each other," Aylin said while they both stood in the cockpit looking out at the stars.

After everything that had happened in the last couple of days, it was difficult to believe that Aylin would be heading home completely unharmed. But she was standing completely healthy in the cockpit of her vessel, enjoying the company of a dangerous yautja, and she felt completely safe.

There was a long trip ahead and Aylin started to get naughty ideas about what to do during the journey to the yautja's home planet.

"I have a suggestion about what we can do with so much free time."

When he finished reprogramming the console and turned around, Aylin leaned over and grabbed his cock. The facial expression of his ugly face was impossible to read, but the reaction of his hardening cock said it all. He was game.

A moment later, the yautja was sitting on the floor of the cockpit while Aylin bounced on top of him, riding his cock. They didn't bother to find a bed before starting to fuck.

His big phallus was penetrating deep into her pussy, filling her completely. She looked intently at his face and something was different. After making her cum so many times, he didn't look so ugly anymore.

The yautja was well aware that this human female had helped him as much as he had helped her. It would be dishonorable to keep Aylin as a sex toy, even though he was very temped to do so. Her pussy was so tight and warm. Fucking her was like a dream come true. He was resting flat on his back while the woman rode him with unrestrained passion. None of the females of his own species had ever been so eager to make him feel this good.

They changed positions after a while and now the yautja was on top, hammering Aylin's pussy with all his might. The overwhelmed woman was pinned down with her legs over his shoulders, receiving his cock even deeper than before.

Aylin felt powerless under the weight of the mighty alien. This was so exhilarating to her that she went over the edge. Aylin exploded in climax, shivering from head to toe while going cross-eyed from the absolute bliss that blasted through her brain. She knew that this orgasm was the first of many. All she had to do was to let him use her body at will.

Aylin turned around with her face resting on the cold floor and her ass high up, readily available to receive a hard pounding from behind. She would be reaching a new orgasm in a matter of minutes.

The yautja could also feel his sperm boiling within his balls. He was trying to pace himself, prolonging this pleasant session for as long as possible. But Aylin's pussy was so tight, that he couldn't hold back any longer. A few seconds later, the yautja reached his climax and so did Aylin. She couldn't understand how she was able to cum so fast after her first orgasm, but it was happening. The creature gushed a large amount of sperm until it filled Aylin's womb, then he ejaculated a bit more. He thought about the possibility of getting her pregnant but it was unlikely. In any case, it would be fun to father a child with this delightful female.

Aylin wasn't thinking about any of that. She wasn't thinking about anything. The waves of utter bliss that traveled across her spine overshadowed everything else.

After a few hours a wild debauchery, the odd couple decided to take a break. At first, the yautja had considered the human female only as a sex toy, but she was so tender and cooperative, that he started to look at her in a different way. Regardless of what the future had in store for them, he had to make arrangements to meet this woman again.

****

It had been only half an hour since they stopped fucking and Aylin's body was already burning with need. Thinking about how many days she was going to spend in this small ship with such a powerful lover made her heart burst with joy and her pussy jolt from expectation.

"Are you ready for another round?" she whispered to his ear.

The End.
