Alternate Earth

**All characters depicted are over 18**

It's so hard to believe it's been 18 years, Dr. Roberts thought as he gazed down at the framed photograph in his hands. It seems like only yesterday that they were just children.

The photograph in the older man's hands depicted a younger version of himself, his brown hair without a hint of gray, holding two identical red haired little girls, about six years old, all grinning for the camera. The pair were dressed in nearly identical sun dresses and Albert, their adopted father, wore a pair of slacks and a short sleeve, button down shirt.

"Daddy," came an inquisitive voice from the hallway.

"Coming, sweetheart." Taking another moment to marvel at how quickly time goes by, the aging professor put the picture back onto the desk in his office and stood to take off his lab coat, exchanging it for a warmer coat of brown wool. He twined the scarf around his neck and went to follow his two not-so-little-anymore girls out into the chill, sunny breeze of a northern California January.

"Hurry, daddy," one of the identical young ladies called as he closed and locked the door to his office.

"We have soccer practice," the other exclaimed, timed and voiced to match her twin perfectly so that it sounded like one sentence from a single voice.

The older man smiled and followed them to his black Toyota Prius Four and got in to drive them the 20 minutes back to school in time for their practice. He had picked them up only two hours before, ostensibly to take them to a medical appointment. He just didn't tell their teachers and school administrators that their doctor worked for him, as did all of the other scientists, medical personnel, and administrators at the Helix Institute.

On the surface, Helix Enterprises is an independent pharmaceutical research and testing company employed by pharmaceutical companies and contracted by the government to do independent testing on various drugs and controlled substances. Dr. Albert Roberts, the institute director and chief scientist, answered only to the Helix Enterprises CEO and the Board of Directors. Beneath the surface, however; the institute and its pharmaceutical research hid much more unusual activities.

In the early days of genetic research, the United States government contacted a group of experts to assess the dangers of unregulated genetic experimentation. The group, meeting just after the 1975 conference on genetic engineering, determined that human and animal rights laws must be in place to prevent the darker horrors of genetic research possibilities. Additionally, the group recommended that a facility, funded by a combination of government money and privately earned income, could quietly research more advanced possibilities and report to various government agencies, such as the Departments of Defense, Agriculture, and Health and Human Services.

Within a week of the meeting, Donald Feurstein founded Helix Enterprises Incorporated and looked across the world for the top geneticists, doctors, and chemical engineers to begin building what would become the Helix Institute. By 1979, the institute began openly doing government evaluations of drugs for the Food and Drug Administration while quietly looking into genetic modifications. Within 10 years, the institute was well past the published accomplishments around the world and had cloned mice and rats more than five years before the 1996 birth of Dolly, a sheep that was accepted globally as the first animal ever cloned. By then, the institute was working on something even more incredible.

Fresh out of the Massachusetts Institute of Technology with a Ph.D. in Bio-Medical Engineering with a focus on genetics, Dr. Albert Roberts began working on actual modification of genomes in embryos. His work was so successful that he received the approval for human trials. In the spring of 1996, Albert genetically modified a male human embryo from unknown parentage, transforming it into a female human embryo with a very specific set of rare, recessive traits. As the embryo developed, however; it split into two distinct embryos and the simultaneous development of twins began. When the mother-to-be expressed reluctance at carrying and birthing twins, the team found another volunteer.

Virginia Driver, a single mother who lost her husband and young daughter in an automobile wreck the year before, volunteered to carry and birth the twins and then raise them as her daughters. After a few months, when the first ultrasounds came back showing that the twins were boys, Albert was devastated. He checked his notes, and requested blood samples, all of which came back showing that the children were female. Bewildered and a bit concerned, the doctor decided to inspect the children when they were born.

During the birth, Virginia had mortal complications and, though both children came through whole and healthy, their surrogate mother died when her heart stopped suddenly during the birth of the second twin. The doctors did everything they could to save her, but they believed that the stress from the birth, combined with the stress and depression from the deaths of her husband and previous child, caused her heart to fail on the operating table. In the wake of the completely unforeseen tragedy, Albert forgot about his research and offered to take the children to raise them as his own.

Over the next month, Dr. Roberts and his team thoroughly tested their genetic work on both twins with near perfect success. The only concern for Albert and his team was that genetically, the children were completely female but had developed both sets of genitals. As their birth was at the institute and, with the uncertainty surrounding their gender, the doctor decided it would be best to raise them as little girls and, if they develop as boys, to change at that time. He had faith in his genetic adjustments and was determined to trust the science, which ultimately turned out to be true... mostly. As a result, their birth certificates reflected their gender as female and their names as Valerie and Niccole Roberts.

Back in the present, the doctor pulled into the lot behind Brickerson Academy, the private school where the twins were in their senior year. Getting out quickly, the two teens ran towards the soccer field with a chorus of "bye daddy," as they sprinted off. Albert smiled as he walked to the bleachers, deciding to watch their practice.

The twins ran out onto the field, waving to their teammates and coach as they fell into the warm ups. Whispering hellos to a few friends, the pair jumped into the practice with enthusiasm. They were only a couple of minutes late and the team had just begun their warm up. Over the next two hours, the girls did a myriad of drills before a short, 30-minute scrimmage.

"Nikki, Val... wait up!"

The twins turned to see Jennifer, one of their best friends, jogging to catch up with them. Smiling, the pair waited and admired the gorgeous creature running towards them. The image of the perfect girl next door, Jenny was difficult to not notice and the two sisters discreetly moved their bags in front of themselves to prevent the inevitable display of appreciation from outing them to their friend and anyone else who might notice.

Jennifer Driscoll was exactly what people think when they hear "head cheerleader," or "most popular girl in school." She was both of those and more. Her long blonde hair fell in silken waves, framing a perfectly sculpted, fine boned face with high cheekbones, a sensual mouth, and large, bright blue eyes. Her tall, slender body curved perfectly in all the right places. Large, gravity defying breasts and an incredible pert, round ass drove the twins, and every boy at the school, into fits. Her 5'9" height also gave her amazingly long, shapely legs. Her incredible looks, combined with a warm, confident personality gave her the run of the school. She became student body president because she never had anything bad to say about anyone and was voted Homecoming Queen almost unanimously. Even though they've known each other since kindergarten, Valerie and Niccole lusted after their friend Jennifer more than anyone else they knew.

"Hey, Jenny," Valerie said, smiling.

"What's up," Niccole asked, finishing her twin's sentence to make it sound like a single voice.

"Isn't your birthday today?"

"Yep," the pair chorused, grinning.

"So what are you doing to celebrate?"

"Well," Niccole started.

"daddy is throwing us a small party tonight," Valerie said.

"but that's just for family," Niccole continued, carrying on the thought in the unusually odd way the twins had of sharing sentences.

"So your big party is Saturday, right? I just got your text before practice. I'll definitely be there."

"Great," they said together.

The three friends continued to chat as they walked to the gate and off the field. When they got to the parking lot, they said their goodbyes and went to their respective cars. The twins watched Jennifer stride over to her Honda Accord Hybrid and admired her thoroughly as she got into the car, waving to her when she looked back. She was completely oblivious to the hard, excited flesh that was painfully hidden in the pants of the two girls waving to her, their gym bags in front of them. Sighing in unison, the pair was about to toss their bags into the back of the blue 2012 Toyota Prius, which used to be their father's, when they heard the door to the drama wing open and the unmistakable voice of Garret as he walked through.

"... but don't let it bother you, girl! You're new so you don't know the politics yet."

"Garret," they both exclaimed, their excitement over Jennifer nearly forgotten, as they ran over and hugged their much larger, boisterously gay friend.

"Well hello, stereo sisters! And Happy birthday!"

"Thanks!"

"I haven't heard anything about a party and that means you're either not having one, which is just sad and depressing, or you didn't invite me, which means I'm going to have to whip your skinny ginger asses." Garret's flamboyant attitude and idle threats made the twins laugh as they spoke.

"Did you check your messages," Valerie began.

"Because we sent the text out before practice," Niccole finished, both giggling.

"Oh, hang on! We've been in auditions all afternoon," Garret explained as he pulled out his phone and looked at the screen. "Oh hey! I got a text from Nikki! Now I don't have to cut a bitch."

Laughing, at the conversation, the twins admired Garret's attractive company and again had to slide their gym bags in front of their waists to hide throbbing bulges. The girl standing quietly but not shyly next to Garret was a little shorter than the twins, probably about 5'3" and had a naturally curvaceous, hourglass figure with large breasts, a slender waist with a flat stomach, and wide hips. Long, shimmering brown hair fell down her back almost to her ass in a cascade of perfectly straight, silken strands. Huge brown eyes dominated a round, attractive face and her plump lips held a hint of a smile. The black T-shirt stretched tight across her large breasts seemed to be for a band but the twins didn't want to stare. All they could see is a yellow snake and an apple with a bite taken out of it. A pair of tight jeans rode low on her hips and exposed just a hint of belly as they hugged her curves.

"Val and Nikki," Garret began after greeting two of his best friends. "This is Amanda. She's a new student and just tried out for "Into the Woods," but got relegated to chorus because Mrs. Jensen didn't recognize her from drama class even though she said it was because she was just not right for the part. I mean really, how is she not right for the lead when Anna Kendrick played it and Amanda is prettier and just as good a singer? I swear, it's all politics and if you haven't taken Jensen's class, you'll never get a lead role. Anyway, Amanda, this is Val and Nikki."

"Hi. Nice to meet you."

"Hi," the twins chimed together.

"What band is that," Valerie asked, both because she was curious and it gave her an excuse to stare at the large chest of their newest acquaintance.

"Oh. It's Corrupting Eve, they've been my favorite band since they came out about five years ago. Do you like metal?"

"Sometimes," Niccole replied.

"We like Halestorm and Sick Puppies," Valerie continued.

"And Disturbed and Shinedown," said Niccole.

"And a few others," Valerie said thoughtfully.

"But not Nickleback," they both chorused, laughing.

Amanda stared at them for a moment, looking back and forth before Garret spoke up.

"Oh honey, they're always like this. You'll get used to it. And I've heard of Corrupting Eve. They're pretty amazing. You two would probably love them."

"Here," Amanda said and pulled on her shirt to make sure the name was straight and easy to read. It also accentuated the significant curve of her breasts. "This is how to spell it."

The twins stared for a moment, swallowing and giving Amanda an odd look for just an instant before they smiled and thanked her. Amanda smiled back and reiterated just how amazing she thinks they are.

"So are you new here," Niccole asked.

"Yeah, dad just started working at that Helix place."

"Oh wow! Our daddy is a director there," Valerie chimed in.

"Really? What does he do."

"He runs the institute," Niccole replied.

"Oh, you're the Roberts twins! I'm Amanda Norton. My dad and Dr. Roberts went to MIT together."

"Wow, what a small world" Valerie said, smiling.

"We'll let daddy know we've met," Niccole continued, matching her sister's smile.

"So what year are you," asked Valerie.

"I'm a senior. I've applied to Berkeley and since dad says I'd get in easier if I'm from California, we moved."

"Oh that's great," the twins exclaimed together.

"We've applied too," Niccole said enthusiastically.

"Awesome," Amanda said, smiling at what she hoped were her two newest friends. "I hope we all get in!"

"So, we're having a birthday party this Saturday," Valerie began.

"since we turned 18 today," Niccole continued.

"Do you wanna come," the twins asked in unison.

"I'd love to!"

The newest friends exchanged numbers and then walked off to their cars. The twins climbed into their Prius carefully, trying not to aggravate the already aching organs dangling between their legs. Simultaneously throwing their gym bags in the back and adjusting themselves with sighs of relief, Valerie turned the ignition and sat for a moment, letting the ache in her loins subside before putting the car into gear and heading home.

"So Amanda was super-hot," Niccole said when they were about half way home.

"Ohmygod I know! And meeting her after seeing Jenny..." Valerie replied, watching the road but noticing the way her sister was massaging the bulge in her track pants.

"I know. I can't remember the last time I wasn't hiding a bulge around her or her boyfriend Rob."

"I feel your pain," Valerie said, reaching down to adjust her own throbbing bulge as she drove. "And the winter formal was torture!"

"I know, right? I felt like Elsa in the first half of that movie," Niccole laughed.

"Seriously," Valerie exclaimed, laughing harder as she drove, "I'm just glad we had dresses that let us conceal, even though I could feel it all night."

The pair both laughed at that and then sighed, their tension easing as the pressure between their legs eased a bit.

"And after the first dance with Handsy Don..." The pair went into another fit of laughter after that.

"Slapping him in the middle of the dance to keep him from feeling your boner... just brilliant!"

"Hey," Niccole exclaimed, her bright green eyes sparkling. "we couldn't both go with our one guy friend who knows, and Don asked."

"I know, Nik. It's just funny. And at least Steve danced with both of us after that."

"Yeah, he's a great friend. And he didn't even get weird when I poked him in the thigh a couple of times."

"He was totally cool with it! When I apologized about it, he just shrugged it off and smiled."

"Val... do you think..."

"No. I asked. He's a good friend but just... he said we weren't his type."

"That's too bad. He's seriously hot."

"I know, right? Hey, pull up Corrupting Eve on Spotify."

"Okay." Niccole pulled out her phone and quickly linked to the car Bluetooth before finding and playing "Wild Magic," the first song in the cue.

The song immediately sucked them in and by the time they got home, they had listened to "Wilting Garden," and "Enter the Witch." The pair were reluctant to stop listening as they pulled into the house, parking next to their father's newer model Prius. Grabbing their bags, they went inside and headed upstairs with a quick chorus of, "hi daddy," before heading into their room to get cleaned up for their birthday dinner.

It might seem odd to their friends, but the twins really preferred to share everything and have been like that since they were infants. While their tastes differ slightly in some respects, and even more in others, they seem to feel uncomfortable when they're not together. They share a room and have shared a bed since they were children. Albert tried to get them to sleep in separate beds but they would just end up sharing on one or the other in the morning.

The pair ran upstairs into their room and closed the door, falling onto each other as soon as the door clicked closed. Valerie, the first in the room, whirled as soon as she heard the door latch and smashed her mouth into her sister's, dropping her gym bag to wrap her arms around the other woman and press herself along the identical set of curves. Niccole, dropping her own bag at the same time, held her twin to her tightly as their tongues danced fiercely, the aching bulge in her pants rubbing against an identical lump throbbing on her twin.

Pulling away from the kiss reluctantly, Niccole grinned and smacked her sister's ass telling her to get undressed and turn on the shower. While their father might know about their relationship, they didn't want to rub his nose in it. Especially since, when he suspected, he warned them that people would not approve of that kind of relationship and would generally be disgusted by it, explaining that there was nothing wrong with it but discretion would prevent those around them from feeling uncomfortable.

Dr. Roberts knew, with their particular physical attributes, that they needed to learn about their differences to normal children early. He didn't want them to be uncomfortable or ashamed of their bodies so he was careful to teach them about the norms of sexuality and morality without pressing them in a particular direction. When they began experimenting with each other, he couldn't find any moral, rational, or scientific reason to prohibit them and he certainly wasn't going to try to use guilt to repress their feelings and cause a myriad of psychological issues. Ultimately, he understood that, as hermaphrodites, they would have a difficult time finding other partners so he couldn't bring himself to discourage them. He also made sure that they were taking a specially formulated birth control for their particular hormonal needs, believing that, if he can't prevent them from having sex, he can at least help them be smart about it.

They quickly undressed and shared another kiss before Valerie scampered off to turn on the shower while her sister picked up their discarded soccer uniforms and warm ups and put them into the hamper. She also put her phone onto their speaker mount and played the rest of the Corrupting Eve playlist. After cleaning up, Niccole moved up behind her sister, her hard cock leading the way, and pressed herself against the identical woman. Feeling the hard meat fit into the cleft of her ass, Valerie leaned back and sighed at the feeling of her best friend and, to date, only lover pressing against her. Looking into the full length mirror on the closed door of the bathroom, the pair smiled at each other.
