The Big Bang Theory: The Parasite

Chapter One: The Joining

“What a crappy crappy crappy day”

Penny thought to herself as she drove her car back to Pasadena in California.

“I mean I even put on a very sexy outfit and all for nothing”

Penny's voice echoed through the empty car as her face turned an angry shade of red as she vented her frustrations about the audition.

A once in a lifetime sci-fi flick opportunity that would have skyrocketed her career.

But instead of a new film role Penny was slamming her hands onto car steering wheel in frustration.

She had put on a tight, red dress that hugged her curves, hoping to land the role of the lead in the latest sci-fi horror flick.

But, as usual, she hadn't gotten the part.

“Sighing in frustration Penny continued her journey along a dark and lonely forest road as she felt a twinge of regret for not taking the role more seriously.

But her thoughts were abruptly interrupted by a blinding flash of light that filled the sky, followed by a thick plume of thick smoke.

Penny’s heart raced as she swerved to avoid the mysterious phenomenon as fire and smoke flew across her front window and before she could react and hit the brakes her car slammed into a nearby tree .

Penny’s face and arms were covered in cuts and bruises as the air bag had deployed helping her to support her lifeless body as she fell ****.

A few minutes later Penny had come to and was partially dazed as she turned her head round to see the appearance of a giant meteor.

As she stumbled out of the wreckage, her thoughts were a blur.

The meteor was like nothing she had ever seen before, pulsing with an eerie energy despite the pain she was in she couldn’t help herself as she stumbled closer and closer towards it.

As she stopped staring right up to the top of the meteor a tiny alien worm slithered out from the shadows behind it, its slimy body glistening in the moonlight.

Unaware of the strange creature heading her way Penny felt the aches and pains of her body but she couldn’t help but be amazed by the sight of the meteor.

“Man I’m amazed I’m still alive, I’m gonna have to show this to the guys”

Penny thought to herself as she tried to reach into her pocket for her phone to call for help.

However the parasitic creature had decided to wasted no time, as it leapt onto her shoe working it’s way up to her body.

Panic began to set in as Penny felt very cold and slime on her leg and as she looked down.

The alien felt the presence of the blondes eyes upon it as it moved even further burrow it’s way through her clothes.

It’s cold, squishy form pressed against her warm flesh as o Penny looked down in horror, but before she could scream.

It had already reached her thigh, and penetrated her pussy as it took a massive leap inserting itself with surprising ease.

The pain was unlike anything Penny had ever felt, but it was quickly overshadowed by an intense, overwhelming pleasure that seemed to flood her entire being.

Her body spasmed as the alien began to take control, sending waves of ecstasy through her core its presence beginning to take root.

She could feel it slithering deeper inside her, coiling around her organs and wrapping itself around her spine.

Her eyes rolled back in her head, and she moaned in a mix of pain and pleasure as it entered her very essence.

Her legs gave out from under her, and she collapsed onto the cold, damp earth,

Her hands no longer under Penny’s control began to tear away at her already torn clothes as her body began shuddering uncontrollably with immense pleasure.

The alien worm was now fully inside of her now, she could feel it wriggling, adjusting, becoming a part of her, becoming one with each other.

The parasite's influence grew stronger, and soon Penny's thoughts were no longer her own but the Aliens thoughts were beginning to merge with her own thoughts.

But she was still trying to fight back as her body continued to move caressing her naked breasts and toned stomach as she lay on the dirt.

The Alien soon took control of Penny’s vocal cords as it began to speak to her using her voice, she could feel its hunger, its need to reproduce and spread.

“That’s it host don’t resist don’t fight me”

The alien parasite said as it spoke through Pennys mouth using her voice as if it were its own.

“Let me take over, let me control your body, together we can have so much fun and pleasure”

“soon we will bring forth more of my kind to this world and you will be their queen, the mother of a new life here on Earth!”

“No noooo” Penny tried to scream out aloud but the alien soon spoke again using her voice

“Don’t resist it feels good doesn’t it embrace the joining”

Penny felt an intense pleasure shooting through her body as if her every nerve was being stimulated to the point of climax by the Alien.

Her body began to convulse and she felt something building up inside her, something powerful.

"You're feeling it now, aren't you?"

The alien's voice echoed through her mind,

"Your body is mine to use, mine now and forever."

As the alien spoke his words of declaration.

Penny's eyes snapped open, now a glazed shade of white, revealing the alien's complete domination.

She looked down to see her hands, no longer under her own control, moving to rip away final shreds of her clothing, exposing herself to the cool night air.

Her nipples were erect and sensitive to the touch, each brush of her fingers against them sending a bolt of electricity through her body.

The alien had taken full command, and she could feel its excitement as it used her to pleasure herself.

Yes, yes, keep going," the parasite hissed through her lips, urging her to explore further.

Penny's hand found its way to her clit, rubbing it in a way that was both foreign and exhilarating.

Her breath hitched as the alien pushed her to new heights of arousal.

She could feel the creature's need, its hunger for more, for complete dominance.

Her hand moved faster, her body writhing on the ground as if possessed by some otherworldly ****.

The pleasure grew so intense that she thought she might shatter from it, her moans echoing through the deserted forest.

Suddenly, she felt something stirring deep within her, something alive and eager to escape.

The pressure grew unbearable until finally, with a powerful contraction, the alien's head emerged from her pussy, coated in her juices.

It was grotesque and beautiful all at once.

Its eyes gleaming with an eerie intelligence.

The creature looked up at her, a twisted smile playing across Penny's features, as if enjoying the sight of her new host.

"Welcome to your new existence, Penny," the parasite's voice whispered as it spoke through her.

"Now, we must prepare for the others."

The creature retreated back inside her, leaving her pussy gaping and wet.

The thought of sharing her body with more of these beings filled her with purpose and excitement in equal measure.

Her mind was a whirlwind of emotions, but the alien's control was absolute.

It began to manipulate her thoughts, guiding her to accept the fate that awaited her.

Penny's hand didn't stop moving as she lay there, lost in the symphony of sensations.

Her other hand found its way to her mouth, her own saliva mixing with the alien's juices as she unconsciously licked her fingers clean as her other hand worked furiously against her clit.

The taste was unlike anything she had ever experienced, a strange cocktail of fear and lust that only heightened her arousal.

The alien worm was now fully in charge, its movements inside her becoming more deliberate and purposeful. It had chosen her to be the vessel for its kind, and she was powerless to resist.

Her thoughts grew hazy as the creature's consciousness merged with hers even more, showing her visions of a world where humans were nothing more than hosts for their offspring.

The creature inside her grew more agitated, and Penny could feel its hunger for more hosts. It was time to act.

With one final thrust of her hands, Penny’s mind collapsed as her body climaxed and came so hard as her body shook violently.

Her juices coming out of her mouth and pussy and ass in great puddles as she fainted on the ground.

Her body covered in dirt as her breasts and pussy and mouth were covered completely in her juices as she fainted.

A few minutes later the Alien having experienced the climax through Penny’s body and mind commanded her to awaken.

With a newfound strength, Penny stood up, her eyes still glazed over now, her mind now completely taken within the alien's power.

“So what should I call you Sir?” Penny asked as her eyes opened fully as she formed a seductive smile.

“Let’s worry about that later for now Human you know what you must do don’t you”

The Alien asked waiting for only answer it wanted to hear.

“Yesss I know what we must do”

In fact Penny knew what she must, what she had to do, bring her friends into the joining.

Her thoughts raced as she stumbled back to her car, her legs still shaking from the overwhelming sensations.

Her body naked still covered in dirt and her juices as the alien whispered its instructions.

It was clear that the parasite had a plan, and it was up to her to carry it out.

Penny knew that she had to get back to civilization, to her friends, to her husband.

But not to warn them, but to infect them.

The parasite had filled her mind with images of her loved ones, their bodies contorted with pleasure as more of its kind burrowed into them.

It had shown her the joy of sharing her body with the creatures, the feeling of them growing inside her, the ultimate unity of species.
