Backdoor Bestiality – Part 1: The Puppy

The year was 2069. In late 2020, the world was almost destroyed when World War III broke out. Atomic bombs were dropped all across the globe and billions of people died. The survivors were forced to take refuge underground. Life was hard, but they managed to use technology to survive. Due to space restrictions, births were controlled and everyone served their purpose. Kids started working at a very young age, but were nothing more than assistants. It was not until their eighteenth birthday that they were allowed to take The Challenge.

The Challenge was a series of five trails that each individual was required to complete. Designed to test a person’s strength and weaknesses, the trails also helped them find a purpose in life. Almost everyone who survived The Challenge knew what they wanted to do with the rest of their lives.

The Challenge itself took place in a very unique building. Some people claimed it was haunted, but the simple truth was, the structure itself was controlled by the most advanced artificial intelligence in the world. Its creator had initially called it Candy and the name had stuck. She was tough, but fair in her testing. But that did not mean passing The Challenge was easy.

Youngsters began training at a very young age and only a few failed The Challenge. Those people were never heard from again.


—Prologue—

Barbie Lez took a deep breath for courage and walked through the hole in the wall. She had just turned eighteen and the time had now come for her to take The Challenge. As per tradition, she was naked from head to toe as she entered the pre-challenge chamber. The wall sealed itself up behind her, leaving no trace of the hole that had only moments before stood there. The young woman had no idea how such a thing was possible, but she had heard wild stories about The Challenge and figured at least a few of them had to be true. Apparently, intelligent material that could be molded at will was one of them. Actually, the entire building was made out of the same material and it was how Candy was able to crate the environments required for a more personalized challenge.

Barbie’s heart raced in her chest as she glanced around the small room. The immaculate white walls formed a circle around her and the ceiling and floor were painted to match. As hard as she looked, she could not discern a single thing. But that all changed in a matter of seconds.

“Fuck!” she muttered in shock as a form suddenly took shape before her. It started off small, but quickly grew into something with four limbs. A human. The first thing Barbie saw were boobs. Firm, d-cup breasts just like the one she sported. The next thing to appear was a pussy. A tight, clean-shaven pussy that looked surprisingly similar to hers. Though she could not see it, Barbie somehow knew a tight, bouncy sss stood behind it. The rest of the body quickly took shape, forming long, platinum-blonde hair, sparkling blue eyes and fleshy lips. But it was not until a large birthmark appeared on the newcomer’s stomach that Barbie finally recognized her.

“Oh my god!” she gasped as she studied the bright-pink, lesbian symbol-shaped birthmark that seemed to hover between the young woman’s pussy and navel. But her shock had nothing to do with the fact the woman standing before her was nothing more than a hologram. Or that she was naked. Her stunned expression was caused by one fact and one fact alone. The breathtaking teen standing before her was none other than her. For a split second, she wondered if she was standing before a mirror. But that theory faded when her replica smiled.

“Welcome,” it said in a voice that was identical to hers.

Barbie remained frozen for a second before speaking.

“Who are you?” she finally asked.

The replica smiled again.

“I’m Candy,” it said. Barbie had to admit it made sense. Candy controlled the entire building and creating a three-dimensional representation of herself was a piece of cake. But one question still remained unanswered.

“Why does she look like me?” wondered Barbie.

“Most people are nervous about taking The Challenge and I have found that taking a familiar form helps calm them down,” explained Candy before Barbie could even voice her question.

Once again, it made sense. But that did not mean Barbie was not totally freaked out.

“Do you mind changing appearance?” she asked. “It’s kind of freaky.”

“Of course,” immediately agreed Candy. And with that, she started to change. “Better?” she asked once the transformation was complete. Unfortunately, her new form resembled Barbie’s mother in every way.

“No!” she almost yelled as she struggled to keep her eyes from making contact with the hologram’s new body. Having to complete The Challenge was stressful enough without having to see her mother naked.

Candy chuckled as she started transforming yet again. When she was done, she had reverted back to a young woman’s body. She resembled Barbie in many a way, yet the teen had never before seen her. At least not for real. Candy now looked like the big sister Barbie had often wished she had. It was still a little creepy, but it was far better than looking at herself or her mother.

“Satisfied?” asked Candy.

Barbie nodded, bringing a smile to the hologram’s lips.

“Great!” chirped Candy joyfully. “Shall we begin?”

Barbie nodded, but the truth was, she was far from ready. She had spent the last few weeks training. Physically, she was ready to take on any challenge, but her mental state was in shambles. She had spent so much time preparing for The Challenge that she had omitted to complete her daily masturbation sessions. For a normal person, that would not have been a big deal, but Barbie was a nymphomaniac and pleasuring herself on a daily basis was the only way she could keep her urges contained. Even worse, she was still a virgin, which meant she could not simply go to a bar and pick up some random guy.

Candy began by reciting a detailed explanation of the challenges she would have to face. But Barbie was too busy freaking out to listen. She had only just realized that the massive amounts of arousal that now coursed through her veins was a constant distraction. And the only way to survive The Challenge was to remain focused on the task at hand.

“Are you all right?” inquired Candy. Obviously, she had sensed the teen’s lack of confidence. But that was to be expected. Candy was part of the building and she could use the intelligent material that made it up to scan the young woman’s body.

“No,” answered Barbie honestly. She then went about explaining the situation.

Candy listened intently and nodded in understanding, though she knew every word Barbie would say before she did. Once the teen had fallen quiet, Candy took a few moments to ponder the situation. But due to her yottabytes of computer power, coming up with a solution took less than a second.

“Not many people know this, but there is more than one challenge,” she explained.

Barbie frowned. She had indeed never heard of multiple challenges.

“There is the main challenge,” continued Candy. “That is the one most people are required to take.” After a short pause, she added, “But there is also the backdoor challenge. As the name indicates, it is an alternate route out of this building and it was designed for those who are not quite ready for the main challenge.”

“I pick the backdoor challenge,” immediately said Barbie, relieved that her aroused state would not lead to her demise.

“Not so fast,” warned Candy. “There are hundreds of backdoor challenges and if you chose to take this route, then one will randomly be assigned to you. But be warned, some backdoor challenges are easier than the main one while others are harder. Before making a choice, you must first decide if the reward is worth the risks.”

Barbie took a few seconds to think things over. Although she had trained for years, her aroused state made it impossible for her to have confidence in her abilities. The backdoor challenge had its risks, but it was better to roll the dice than to insure her failure by choosing the main challenge. Plus, the sight of Candy’s naked body was driving her wild with desire, even though she had never before had a lesbian thought.

“I pick the backdoor challenge,” she finally said.

“Very well,” said Candy. She then used her limitless intelligence to randomly pick a challenge.
