****** Unexpected (a Pinecest Story) ******
by Edward_or_Ford
Summary
     Young love blossoms where it shouldn’t. What will happen when it
     appears that a new life has been formed from this love?
Notes
     We aren’t just dealing with sibling incest here. Taking place over a
     period of several years, this story involves underage Pinecest, with
     pregnancy thrown in for good measure. If you will find it disturbing
     to read about fifteen-year-old siblings, dealing with the possibility
     of getting ready for a baby, please do not read this!
     Despite the circumstances, this is above all a story of love, and how
     a young couple in an incredibly difficult situation deals with their
     love. I hope the characterisations are reflective of Dipper and
     Mabel, and that the emotions ring true.
***** Part 1 - Infatuation *****
***** Spring 2012 *****
Dipper wiped his brow. Spring cleaning was hard work!
The Pines family was engaged in that age-old practice of getting rid of things
they no longer needed. Seemingly every year, new “stuff” would accumulate,
meaning there were older belongings that probably didn’t need to be kept. On
this Saturday in April, it was the basement that needed to be tackled.
They had sorted through enough old things that had been deemed expendable,
including a couple of small pieces of furniture, that it would take more than
one trip in the family car to haul it away to the donation depot. Dipper’s twin
sister Mabel beat him to the punch when their father asked for a volunteer to
go with him to deliver the first load, so this left him at home with his mom.
While she started preparations for dinner, she asked Dipper to go back to the
basement to sort through one last box before the others got back.
He sulked at the added work. This wasn’t fair! He was twelve years old, and it
seemed lately that he had more responsibility than Mabel. He grumbled to
himself as he descended the stairs. Dipper's task was to go through the
family's box of old VHS tapes of cartoon movies that the twins never watched
any longer. He was to make sure there weren’t any irreplaceable home videos
mixed in.
After wrestling the box loose from where it was stuck in the corner and
dragging it to where he had more space, he pried open the lid and sighed at the
stacks of tape boxes. One by one, he took them out to examine the titles, and
to make sure the tape inside matched the box. Sure enough, they all seemed to
be old Disney movies, Nick Jr. television series, and other kid’s programming.
None ot these had been watched by either of the twins in years, either from
lack of interest or because they’d been replaced with DVDs.
There were only about a dozen or so tapes left when Dipper noticed the bottom
row of tapes were not in plastic hinged boxes like the rest, but instead were
in standard cardboard sleeves. He examined the titles: “Risky Business”, “48
Hrs”, “Ferris Bueller's Day Off”, “Raging Bull”, “The Shining” … Dipper didn't
recognize any of these. Someone had obviously shoved some old collection of
less kid-friendly movies into the box. He thought his parents might think them
worth saving, and he started gathering them into a separate pile to bring up
and show his mother.
Then he picked up the last tape in the row of old films, and looked at the
title: “The Blue Lagoon”. He’d never heard of this one any more than the
others, but he was certainly intrigued by the cover art on the box: a photo of
a young teenage boy and girl holding each other close, and both appeared to be
wearing nothing more than tiny loincloths. The girl’s breasts were covered only
by her hair. Dipper was feeling the familiar funny tingling in his groin he
would experience anytime he saw sexual stuff on the Internet he knew he wasn’t
supposed to see.
After finishing the last of the tapes and verifying there were no home movies
among them, he began stacking the children's tapes back into the box for
giveaway. Then he stopped, and glanced nervously at the staircase. Very
quickly, Dipper emptied the box again and put the old grown-up movies back in
the bottom of the box, where they would stay hidden. All except one tape. The
cartoons and kids programming went into the box next, and he closed the lid.
With “The Blue Lagoon” tucked under his armpit, Dipper ascended the stairs to
the main level, calling out to his mother that the box was too heavy to lift.
When she replied from the kitchen to leave it for now, he swiftly dashed up to
the 2nd story and to his bedroom. Carefully, he hid the tape in a dresser
drawer with his clothes. Closing the drawer again, he determined to wait for an
opportunity to see what was up with the curious-looking movie.
===============================================================================
 
By the time the school year ended two months later, Dipper had been left alone
in the house for any appreciable length of time on just three occasions. The
movie was watched, not coincidentally, three times in that span.
The boy's immature hormones stirred with each viewing of the movie. The story
was of two children, young cousins, tragically stranded alone on an idyllic
tropical island. It started showing the cousins as prepubescent kids, but the
majority of the film portrayed the kids as teenagers after several years had
passed. There was little left to the viewer’s imagination as the kids were
shown falling in love, discovering sex, and even having a baby together! The
young actors rarely wore more than tiny garments around their waists, and often
they were completely naked. Dipper was amazed that such a movie could be
allowed to be made, but he certainly wasn't complaining.
The movie did more than cause arousal, making Dipper have an erection. In his
imagination, he also couldn't help substituting himself and his sister into the
roles of Richard and Emmaline. The dynamic of the characters was familiar: they
were playmates and friends, they helped and cared for each other, and they got
into disagreements and fights: all of this was just like Mabel and himself.
They had a very close sibling relationship already, but Dipper felt strange
about the idea, if he and Mabel were the ones stranded alone, that he could
kiss his sister. Or that he could make love to her. Or that they could have a
baby together! He knew it was a weird daydream, and he was ashamed of thinking
about Mabel like that. But every day, and most nights, Dipper continued to
dream of living like that with his twin.
Just a couple of days into summer vacation, his fourth opportunity came. His
parents left for the outdoors equipment store, but didn't tell him what they
were shopping for. Mabel had already gone out to play with neighborhood
friends. As soon as the car had left the driveway, Dipper dashed upstairs to
retrieve the tape from its hiding spot.
After putting the tape into the living room VCR, he ran back to the couch. He
had left the tape queued up to the beginning of the scene where the cousins go
skinny dipping together, which would lead to the part where they made love for
the first time. He was enraptured, his penis already hard in his shorts, as he
watched.
Then without warning, Mabel bounced through the front door. “Diiiiiiiip! I’m
borrrrrrrrrrred! Everyone’s gone to do other stuff!” She turned to close the
door quickly before Mittens, the family’s notoriously moody cat, could escape
outdoors.
Dipper mashed the “stop” button on the remote, then launched himself to the VCR
to hit eject. The machine made strained mechanical noises at it prepared to
return the tape, a process seemingly requiring several hours, from the panicked
boy’s perspective. By the time Mabel stepped around the corner carrying the
cat, Dipper had the tape in front of his crotch, trying to appear
inconspicuous, and the television was glowing bright blue.
“Whatcha watching? Some nerd thing?” Mabel asked with a bright smile.
“Uh! Uh … it’s nothing!” stammered Dipper as he turned off the TV and stepped
around his sister, heading for the stairs.
“Oh! Oh! It’s … it’s nothing!!!” Mabel mocked happily in her brazen yet somehow
charming style. “Come on, Bro! Show me!” she called out to him while she
struggled to hold the squirming feline.
Dipper was already starting up the stairs. “It’s really nothing important,
Mabel! It’s a … a documentary! It’s like a science documentary on … biology!”
he shouted as he disappeared into the upstairs hallway.
“Borrrrrrring!” Mabel groused again loudly, gently dropping the cat down on the
floor. “I never thought I’d wish we were still in school! Is it going to be
like this all summer?” Dipper came back down the stairs, his old PlayStation
Portable in hand. “Let’s dosomething, Dipper! Your dear sister’s dying here!
It’s like we’re stuck on a desert island!” The handheld slipped from Dipper’s
hands and clattered to the floor. “Hah! Butterfingers!” commented Mabel with a
grin full of braces.
“Yeah …” replied Dipper, flustered. He picked up the game and looked around,
wanting to redirect Mabel’s attention somewhere else. “Okay, how about … a
race? You try to … get Mittens to purr before I finish a lap of Sonoma on Gran
Turismo?”
Mabel scratched her chin in an exaggerated manner. “Hmm! My irresistible charms
on the grumpy Mittens McMittenFace, versus your girly-gaming skills. Okay,
you’re on!” She ran to pick up the cat, carrying it back to where Dipper stood,
his thumbs ready. Mabel calmly started rubbing and stroking the big fuzzy cat,
making little cooing sounds. Dipper shifted, looking for the signal to begin. A
small evil smile broke on her face. “You waiting for something, brother?” she
asked slyly as she continued petting the squirming Mittens.
“Agh! No fair!” Dipper cried out laughing, launching his Corvette from the
starting line. As he drove around the twisty circuit on his game console, he
also thought about how happy he was with how well he and Mabel got along. She
really was a perfect sister: fun, adventurous, always had his back, and was
never malicious in her teasing. He really liked being with her, and couldn’t
imagine growing up without her. Weird fantasies or no weird fantasies. Not that
he still wouldn’t thoroughly enjoy beating her at this little contest, he
thought, as he braked hard for Turn 7 and aimed to navigate around the tricky
corner.
Their parents came through the front door, loaded down with bags and bulky
packages. “All right, kids, listen up! Big news!” called their father. Dipper
and Mabel muttered replies distractedly.
Seconds later, their mother was taking Mittens from Mabel’s arms, while their
father snatched the PSP from Dipper. Then brand new bags and packs were dropped
in their arms, a new cap was plopped on Dipper’s head, and just for fun, a
small dollop of sunscreen was smeared on their noses. Both of them looked up to
their parents in confusion.
“You’re going to have a big adventure,” their mother told them. “You’re going
up north to Oregon to spend the summer with your Great Uncle Stanford!”
The twins looked at each other uncertainly.
===============================================================================
 
***** Autumn 2012 *****
Mabel tried to immerse herself in knitting her new sweater. But she just wasn’t
into it. She set her knitting needles aside and flopped back onto her back,
allowing Waddles to nuzzle up to her from his position on much of the rest of
the bed.
It had been one heckity-heck of a summer! She and Dipper had, over less than
three months, been through an incredible series of amazing and terrifying
adventures. A far cry from her initial desire for an epic summer romance, which
seemed like such a small thing now. Instead, she’d gotten to know and love not
just one, but two fantastic great uncles, made life-long friendships, seen
incredible supernatural phenomena, and helped win a battle with an actual evil
demon!
But every day that passed, since they arrived home in Piedmont a week prior,
made the memories of what happened seem more and more unbelievable. No more
quirky townsfolk, no more crazy creatures, no more magic. Just the same old
school, dull friends, bland suburbia. Everything special was gone!
Well, not everything. Most special of all, she at least still had Dipper! The
summer had cemented her bond with her closest compatriot and best bro ever. She
could never forget how much of a part of summer Dipper had been with her. She’d
always treasured how great he was, for as long as she could remember, but this
summer had seen him become so much more! He was stronger, braver, cleverer, and
more adorkable than ever.
It really scared her when she thought he’d be staying with Grunkle Ford after
the summer, that she’d have to go back to her old life alone, trying to grow up
without him. She had found the bubble Bill had made for her to be a perfect way
to just deny her heartache over feeling so abandoned. But when Dipper had told
her he had changed his mind, that he wanted them to grow up together after all,
the relief and happiness she felt was immense.
And she felt more than that, she recalled. When Dipper had testified at his
“trial” that he wanted to stay by her side, he had punctuated the point with
the same “Yes. Definitely. Absolutely!” that she had used at the beginning of
the summer when she wanted to find a summer boyfriend. The connection made her
heart do that flittery-fluttery thing that happened when she had thought of
potential romance. She realized Dipper would be perfect boyfriend material,
were it not for the fact he was her brother. Mabel found, to her surprise, that
she felt more saddened than disgusted by the thought.
All this made it really hard to get back into the old routine, though! Come on,
schoolwork? After all that she’d seen and learned? And even worse, now it was
the weekend, and there was even less to occupy herself with. Even Dipper had
gone for the day with their Dad to San Francisco on an errand.
What would Dipper do if he was bored like this, she wondered to herself?
Probably read yet another dumb nerd book, she answered. There’s never a lack of
books! Dipper should never get bored!
But what the heck, she finally considered. There’s gotta be books in this house
that aren’t terrible. Mom had used to read novels all the time, she thought. I
should read one of hers. Mabel wandered out to the backyard where she found her
mother watering flowers, and asked if it was okay to try reading one of her
paperbacks.
Her mother turned off the hose. “Hmm, I got rid of most of my books, but I’ve
still got one shelf of old novels. They’re on the bottom of the bookcase in the
study. Have a look there.”
“OK thanks Mom,” Mabel replied. Returning to the house, she found the shelf in
question. There were two rows of books. She randomly picked a couple, but none
of them grabbed her interest. Most of the novels were random single edition
books by different authors. Then she noticed a row of similar-styled books, all
written by the same author: V. C. Andrews. Curious, she pulled out the first in
the line and read the title. “Flowers in the Attic,” she mumbled aloud,
thinking about the attic that had been her home all summer.
She flipped the book over and read the back cover synopsis. Her eyes widened as
she saw that it was a story about four siblings locked in the attic of a
mansion, with no one they could depend on but each other. The last two
sentences took her breath away: “Chris and Cathy become all things to the twins
and to each other. They cling to their love as their only hope, their only
strength -- a love that is almost stronger than death.”
Mabel immediately thought of how if she were in this story, she could never
have a better companion and protector than Dipper. The book was building these
siblings up to be needing each other to handle a really hard challenge. Well,
she and Dip had faced pretty darned challenging stuff, too! How would these
siblings compare to the Mystery Twins, she wondered?
Sauntering back up to her room with the book in hand, Mabel hoped she had beat
boredom, at least for a little while.
===============================================================================
 
Emotional upheaval during adolescence is nothing new for thirteen-year-olds.
But due to the unique events they'd experienced together, the Pines twins were
feeling the effects of new hormones in a way most young teenagers would never
have to.
Mabel had read a great many romance novels before, but none that had ever
affected her anything like the V. C. Andrews books had. Mabel consumed all the
novels on the shelf as quickly as she could, but it was the first series,
“Flowers in the Attic” and its sequels, that impacted her the most. The story
focused on a brother and sister who came to fall in love as they coped with
terrible abuse towards them and their younger siblings at the hands of their
family. Although there were all kinds of issues with their relationship, there
was something so pure about the love that Chris and Cathy shared, something so
right.Something perfect! Something that was just like the way she felt about
Dipper, and how she knew Dipper felt about her. By the end of the second novel
in the series, it had shown how that kind of love could become more, could
become romantic, passionate, and unbridled. That their love could be physical.
That they could be complete, together! One of these books was in her hand late
at night, barely a week after she’d found the novels, when she envisioned
herself and Dipper holding themselves tightly together, keeping each other
strong and safe from the dark forces of the world. Their clothes would fall
away and their embrace, their bond, would be even closer. She caressed and
rubbed herself as she imagined her brother sliding inside her, moving lovingly
within her, knowing that was where he belonged. She gasped in desperate need,
thrusting a finger in and out to tickle that special spot and augment the
stimulation she gave her clitoris, finally experiencing the release of the
first orgasm of her life. She’d had countless more since, and every one was
with Dipper first and foremost in her mind.
At the same time, Dipper had to deal with his own longing for his sister. Their
adventures of the summer in Gravity Falls had been amazing, and after it was
all over, he shuddered to think of all the things that had happened. Putting
aside the supernatural weirdness and his hero-worship of his Great Uncles, that
fact that he’d shared those thrilling months with Mabel stood out most of all.
Sure, he’d been stupid every now and then: he still didn’t believe he actually
considered staying behind to be some kind of apprentice, and thank god he
realized what a mistake that would have been. What he remembered most were the
times Mabel was hurt or in danger, when he hadto protect her. After losing her
for days to Bill's bubble at the end of the summer, he finally knew he would do
anything, anythingat all, to get her back. He would sacrifice everything for
her safety and happiness! He knew this was far beyond what he had ever felt for
Wendy. Where he had merely wanted Wendy, he needed Mabel! In his bedroom, about
a month after starting school, he was overwhelmed with these intense thoughts,
compelling him to give vigorous attention to his penis. He flexed his pelvis
and stroked himself faster and harder than he ever had before, imagining in his
mind that he and Mabel were in the Blue Lagoon, naked together, passionately
making love on the beach. He would never forget the incredible sensation as he
climaxed for the first time in his life and ejaculated all over himself and his
sheets.
As much as they both knew their feelings were forbidden and should have made
them feel gross, they couldn’t help it. Neither could gather the courage to
admit it to their twin, and barely wanted to admit it even to themselves, but
Dipper and Mabel had completely fallen in love with each other.
===============================================================================
 
***** Part 2 - Obsession *****
***** Spring 2013 *****
Dipper and Mabel continued their final year of middle school, closing in on
completing the eighth grade, preparing for the transition to Piedmont High
School. Dipper was at or near the top of most of his subjects, and Mabel was a
solid student who was president of the Spirit Club. As spring set in and
graduation was approaching, the school year had been completely successful for
the Pines twins so far.
Outwardly, at least. Inside, that was a different story.
Their secret feelings for one another had continued to grow. But they still had
to keep up the appearance of normalcy. Even though they both ached inside
because of their longings, they were resigned to never being able to act on
them. Somehow, they both had to suppress their thoughts, which they believed to
be depraved, and deal with the fact that life would have to go on. School
assignments and extracurricular activities helped, so as much as possible they
buried themselves in their work.
===============================================================================
 
“We’re going back to Oregon this summer?” Mabel asked. “Why?”
Dipper agreed. “Yeah, we thought Grunkle Stan and Great Uncle Ford wouldn’t
even be there!”
Their father confirmed Dipper’s statement with a nod. “That’s true, kids. Your
grunkles left last week for the far North, and summer is the only time the sea
ice breaks up enough for them to go. They won’t be back until mid September.”
“But today while you were at school, we talked on the phone with your friend
Soos,” their mother continued. “He asked if the two of you could go up again
this summer. You could work for him and his fiance at the Mystery Shack, earn
yourself some spending money, and have fun. Same as last summer!”
Dipper and Mabel exchanged looks. They had never relayed most of the stranger
events of the last summer to their parents, particularly those that Mayor
Cutebiker had decreed to be part of “Never Mind All That.” The twins sure hoped
that another summer wouldn’t bring more of the same weirdness, for they had
barely gotten out alive.
Also running through their heads was the sleeping arrangements. They knew that
Soos and Melody had converted Ford’s old room into their bedroom, and Soos’
Abuelita had moved into the bedroom that had been Stan’s. That meant that
Dipper and Mabel would be sharing the attic again. The idea thrilled and scared
them, but they couldn’t let the other know anything about those emotions.
Regardless, the decision was made for them. Dipper and Mabel’s middle school
graduation would take place at the end of the week, and then they would board a
bus the day after that. They had to be prepared for another summer in Gravity
Falls, whether they thought they were ready for it or not.
===============================================================================
 
***** Summer 2013 *****
Gravity Falls would always be a bit of a strange place. After all, there were
gnomes, manotaurs, unicorns, and any other number of weird creatures that lived
in the woods near the Mystery Shack. But with the defeat of Bill at the end of
his Weirdmaggedon, much of the town’s danger had disappeared.
And of course their great uncles were not around. Grunkle Stan had been such a
huge part of their summer the last year, and Grunkle Ford, quirky as he was,
also had been beloved. But they were off on their own adventure.
Plus their other friends in town weren’t around. Pacifica had responsibilities
at home, learning the ropes of honest capitalism along with her father. Candy
and her family had moved away, and Grenda had been taken on a summer-long trip
to Austria with her parents by her boyfriend. And their older friends,
including Wendy, were largely busy with summer jobs.
With the help of Melody and the support of his grandmother always nearby, Soos
became a quite capable businessman. Tours through the exhibits were orderly and
entertaining, and the Mystery Shack became a well-oiled enterprise. Dipper and
Mabel had regular hours of work, predictable days off, and were paid fairly for
their labour.
Coupled with having seen so many unfathomable things the year before, the
returning Pines twins found their second summer vacation in Gravity Falls to be
… boring! All the spontaneity and adventure was missing.
As a result of this, the twins didn’t have any distraction from each other, and
their uncomfortable secrets they kept from one another.
===============================================================================
 
“We’re the place where the ducks roar, and the bears quack!” proclaimed Soos
loudly. “Congrats, Dudes! You survived the Mystery Shack!” He smiled proudly as
the large group of tourists laughed at the charming Mr. Mystery’s rhyme. Soos
had just completed his usual great job of being a guide to the Shack’s
attractions. The visitors started filing out the door, with a few finishing up
their purchases of souvenir trinkets. He followed them out, chatting up the
customers, knowing that they would tell others of how wonderful their host had
been while visiting the quirky tourist trap. Melody winked at him, and Soos
returned a happy thumbs-up.
Melody finished straightening up a rack of postcards, then patted Dipper on the
shoulder as he swept the floor. “You alright, Dipper?” she asked kindly. “You
look a little tired.”
Dipper nodded as he continued his work. “Yeah, yesterday was a long day,” he
replied. “I'll be okay.”
“Sorry to have to put you to work so soon, but we’re in for a busy day today.”
Melody sidled up to Mabel as Soos was outside waving goodbye to the group as
they were queueing to get on their tour coach. “Nicely done on the cash
register, Mabel,” she said admiringly. “You just got off the bus yesterday.
First day back and you’re in the swing of things quickly!”
“Pfft! You didn't see me last summer!” she joked. “I'm still scraping nine
months of rust off these fingers! Wait’ll you see me in another couple of
days!” Mabel made a silly grin as she flexed her fingers dramatically.
Melody laughed with delight. “Does your sister ever turn off the goofy
attitude?” she asked Dipper, who was sweeping the floor.
“Nope,” Dipper smiled fondly. “I haven't found the off switch yet.” Mabel blew
a good-natured raspberry towards him.
“Soooo …” Melody said, glancing at Mabel knowingly, “I remember you being Soos’
dating coach last year. You did a great job! Are you … taking your own advice
these days? How's that search for romance coming?”
Mabel couldn't exactly say she had already found the boy of her dreams, and
that he was a few feet away holding a broom. But she also knew that she was a
horrible liar, and if she tried to say there was no one, it would be an obvious
fib.
“Well, there … is someone I like,” she replied, feeling her face flush. From
the corner of her eye she saw Dipper turn towards her. She quickly turned back
to Melody, forcing a grin on her face.
“Oh, ho!” Melody exclaimed. “A boy at your school?”
Mabel shrugged, hoping Melody would drop it. “Yeah, he goes to my school.”
“Really?” inserted Dipper nonchalantly as he resumed sweeping. “I never heard
about this …” He left off the next question, the one he didn't really want to
know the answer to: the identity of the boy Mabel liked.
Mabel was not going to volunteer that information in any case. She quickly
recycled one of her lines from the previous summer. “I don't tell you
everything!” she teased with a large smile.
Dipper feigned disinterest and went back to his cleaning duties while Mabel
changed the subject and continued chatting amicably with Melody, this time
about the relief of no longer enduring metal on her teeth.
===============================================================================
 
In the dark of the attic that night, Dipper lay wide awake. He was exhausted,
but how was he supposed to sleep?
The previous night had been his first night sleeping in the same room with
Mabel since last summer. He was telling the truth to Melody: it had been a long
day, what with traveling by bus for 14 hours, including a transfer. Soos and
Melody had their beds already made up, and they quickly went upstairs. He was
able to disregard how weird this was going to feel, at least for the time
being.
Dipper had fallen into a light sleep instantly, but the lack of background
noise left him hyper-aware of small sounds. As a result, he woke up slightly
when he heard Mabel shift her position. Facing away from her, he was about to
drift back off again when he heard Mabel's breath quicken, and could barely
make out a tiny rhythmic squelching noise that was in time with faint rustling
of sheets.
He had instantly become aware of what Mabel was doing. He didn't think it was
right to listen in, but letting Mabel know he was awake would have been even
worse! Trying to keep his own breathing as quiet as possible, he had to lay
still, his erection straining, as he could hear Mabel gradually work her way up
to completion. It was almost painful to listen to the stifled squeak from her
throat, accompanied by rapid wet rubbing noises, as she climaxed. Dipper was
awake in frustrated arousal for at least an hour after that, and then had
erotic dreams when he had finally fallen asleep. Horrified, he'd awakened in a
sticky mess, as he'd had a powerful wet dream about Mabel. He managed to get to
the shower without being noticed, but it didn't prevent him from being
tremendously anxious and embarrassed.
Now it was the following night, and on top of everything else, he was jealous!
Mabel's statement that there was someone at school she liked … it tore at him.
This mystery boy was obviously who Mabel had been fantasizing about the
previous night in the dark. The guy was so lucky! What he wouldn't do for Mabel
to feel that way about him, instead! Dipper wanted to be the one making her
feel loved and special, making her feel pleasure. For his fingers to be running
over her skin, then probing her mysterious nether regions for her. He wanted
her to feel his urgent kisses on her lips, and his tongue and gentle lips on
her breasts. He wanted her to feel him pushing himself into her, make her know
that he loved her more than anything …
Dipper couldn't take it anymore. He was as hard as he could remember, and he
needed release. He listened to Mabel's deep, regular breaths, glancing over to
her peaceful, relaxed face. “Mabel?” he whispered, trying to make sure she was
asleep. Her light snoring continued uninterrupted.
Beneath the covers, Dipper carefully pulled his shorts down below his knees and
pulled one leg out to free his movements. Then he grasped himself and very
slowly began stroking, the naturally-lubricated foreskin gliding down over the
uncircumcised head with each downward pull.
His breaths came a bit quicker, more labored, as he allowed his pelvis to
thrust up slightly with each agonizingly slow pull. He knew he had to keep
quiet. Mabel’s breathing sounded the same as before.
Dipper had never had to be this careful, had never taken this long with his
masturbation sessions. The pressure built in his groin as it never had before.
Unwittingly, the pace of his movements gradually increased. He struggled
mightily to keep silent, breathing in tiny shuddering gasps. He barely
processed the light fapping noise he was producing as he imagined Mabel moving
on top of him, his penis deep inside her, his sweaty skin pressed against hers.
Eventually Dipper began feeling the delicious tightening, and he knew his
release was imminent. He squeezed and pulled even faster. Then he realized with
a start that he had nothing to “catch” his semen with. In a panic he sat up,
yanked off his t-shirt, and threw it around his jerking hand and penis barely
in time. He winced hard as the biggest orgasm of his life hit him, and he
erupted repeatedly into the shirt. A whimper escaped his mouth before a huge
intake of breath. Then he was panting quickly, his body deprived of oxygen as
his penis produced the last drops of his seed.
As he calmed down, he glanced over to the other bed, thankful that Mabel had
not moved a muscle. It would have been the most embarrassing moment of his life
if she'd known what had just happened. He wiped up the remnants of his mess
with the shirt, quickly tossing it down into the gap between his bed and the
sloped wall. Pulling his shorts back on, he collapsed carefully back onto his
pillow.
Finally relaxed, his chest rising and falling quickly but gently, Dipper again
turned his head to gaze at the beautiful, sleeping face of his sister. His
heart squeezed in pain for an instant, knowing everything that he felt for
Mabel was wrong, and that she could never feel the same way about him in
return. A tear formed in his eye, and he quickly wiped it away. Finally, the
fatigue from lack of rest and the hormones released from his orgasm combined to
allow him to fall into a blissful sleep.
As soon as Dipper's snores became deep and regular, Mabel's eyes opened. Hours
passed before sleep claimed her again that night.
===============================================================================
 
Soos and Melody disappeared from sight, still waving goodbye from the side of
the road as the bus rounded a corner and headed for the highway.
Mabel exhaled dramatically and flopped her head on Dipper's shoulder. “Heck of
a way to celebrate our fourteenth birthday, huh Bro?” she muttered.
“Yeah, we've definitely had better,” Dipper grunted in reply. “Especially since
our birthday was a Saturday this year. You’d think Mom and Dad could’ve driven
up to pick us up, so we could have a nicer day instead of an all-day bus trip.
Kinda spoils the fun!”
“They said they couldn’t leave Waddles alone in the house, and it’s too far to
take him up and back at once,” Mabel said, defending her pet from any hint that
the pig was at fault for their situation.
“Okay,” Dipper grumbled, “But it still sucks.”
“Yeah,” Mabel agreed. “I don’t even feel like playing ‘bus seat treasure
hunt’.” Dipper leaned his head onto hers in sympathy, causing Mabel to tuck her
chin in comfortably. It always made her feel instantly better when she could
have cuddle time with her Dippy Ruxpin. “I guess all told, though, it wasn’t
that bad of a summer! I mean, you’re glad we came back, right?”
Dipper couldn’t stop a small smile from growing. “Yeah, I am. Maybe it wasn’t
as incredible or unbelievable as last year, but it was fun! We got to kick back
a lot more this summer, didn’t we?”
Mabel smirked. “Yeah, not quite as much screaming and running for our lives,
huh? I think after a while, that started to wear a bit!”
They started reminiscing about the crazy events of the previous summer,
laughing at the silly and happy memories, neglecting to bring up the scary and
horrific ones. They also replayed some of their recent fun times of the summer
just concluded.
Unmentioned were the subjects less comfortable to talk about. Things like how
Mabel started noticing just how often Dipper demonstrated his cute protective
tendency, while Dipper began more and more appreciating Mabel's efforts to draw
him out of his shell. And like how they each noticed the way their siblings
looked better in their swimsuits at the pool than the previous year. And, of
course, their silent observations of each other's occasional masturbatory
practices were also ignored.
They had both successfully learned to push down their secret longings for one
another, and to only show the genuine sibling affection that they still felt
for one another. They laughed together as they recounted the best of their
memories, then started thinking about their immediate future.
“So … what about high school?” Dipper asked. “We start in a few days. You ready
for it?” Dipper's voice became more tentative.
“Nope!” Mabel replied immediately, then a little quieter, “but I guess we
gotta, huh?”
“Yeah,” Dipper said grudgingly. “Back to the bottom of the totem pole. I’m not
scared of the work or anything, but I know what it’s going to be like. You know
… nerds don’t exactly get an easy ride.”
“Dipper, you’re the best kind of nerd,” Mabel shot back. “You’ll be so busy
leading the math geeks team, and your dumb DD&MD club, and whatever else you
wanna do, you’re gonna run the school. You’ll do fine!” She punched Dipper
lightly on the shoulder, drawing a half smile from her brother. Then she
slouched and put her head down. “It’s mewho’s not gonna fit in!” she said with
a frown.
Dipper scrunched up his face in confusion. “Wait what? Why do you think that?”
“Come on, Dip! You know I’m still just a goofy little kid! I’m not close to
cool enough to fit in at high school, not the way my weird brain works, man!”
Mabel turned her head to peer up at Dipper. “I mean … I like being silly, you
know that!” she said with a brave smile. “And that’s fine for middle school, I
guess, but … there’s going to be seventeen-and eighteen-year-olds there! It’s
no place for a little freak show like me!”
Dipper nudged her shoulder with a grin. “Mabel, they'll belining up to be part
of your freak show, I guarantee it! I know I'll be buying a ticket!” Mabel
nudged back half-heartedly, but Dipper could tell that she was still
unconvinced. “Seriously Mabes. Square pegs in round holes: that's us! We'll
help each other through. We always have!” Then it was Dipper's turn to twist
his head away slightly. “Unless … you don't wantme to hang around with you
anymore …”
Mabel looked astonished. “Dipper … who said I don't want you with me? I never
said that!”
“Well … well not exactly, but …” he stammered, suddenly feeling the urge to
scratch the back of his head. “You … you said … back when we first came up here
a couple of months ago, you told Melody there was a guy at school you really
... liked… and I just figured you’d … I don't know, you'd want to try to be
with this guy or something ...”
Mabel remembered the conversation, and hadn't realized it bothered Dipper so
much. She'd been trying to cover up that Dipper had been the guy she liked, but
instead made him feel abandoned. And he had nursed that feeling all summer! The
poor goober! “Oh, poop, Dipper!” Mabel said warmly. “How could I want to be
with some other guy when I’ve got you!”
Dipper turned back and looked at Mabel strangely, and she realized how that
sentence had sounded. It sounded altogether too much like the truth!
“I mean, hah hah, I was just jokingwith Melody about there being someone! You
know … didn’t want her to think I’m a flop at the old game of love, am I
right?” Mabel proclaimed, grinning. “And of courseI want to hang out with you!”
she added.
“Yeah, okay,” Dipper replied after a moment. He paused again, clearly trying to
make up his mind about something. Then he blinked twice and took a breath
before continuing.
“I always want to hang out with you, Mabel,” he said quickly, a tiny catch in
his voice.
Mabel blinked in return, her nervous grin frozen on her face for an instant,
then it melted into a genuine, affectionate smile. “Dawwwww …” she cried
quietly. “I need a big one of those awkward hug thingies!” She pushed her arm
around his back and leaned over to squeeze her brother, her cheek pressed
against the front of his shirt.
Dipper returned the hug tentatively for a few seconds, then more tightly and
comfortably as his jaw rested on Mabel’s head. They held the embrace for a long
moment.
“Happy Birthday, Bro Bro,” Mabel murmured into Dipper’s chest.
“Happy Birthday, Sis” Dipper replied softly, his lips lightly brushing the top
of her head.
With a quick “Pat! Pat!” and a fond chuckle, they released one another
reluctantly, then rested their weight against one another again to get
comfortable for the hours of bus travel to come.

***** Part 3 - Revelation *****
***** Autumn 2013 *****
“Help me set this up, Dipper!” Mabel demanded cheerfully, flopping forward onto
Dipper’s bed while holding her new laptop, an early Christmas gift from their
parents a few days before.
Dipper was bouncing lightly from the impact of Mabel’s weight on his mattress,
and glanced up with a small smirk from beside her on his bed. He was sitting up
with his back against the headboard, reading a novel. “Once again, you need the
assistance of the resident computer geek, huh? Maybe you need to pay for a
support contract?”
“Aw, you have to help me, Dip!” Mabel shot back in a fake whine. She rolled
over towards him onto her back, her head coming to rest in his lap. Her upside-
down face gazed pleadingly up into Dipper’s, eyes huge and bottom lip thrust
out pathetically.
The smirk on Dipper’s face widened and he rolled his eyes. “Hopeless!” he
taunted.
“As hopeless as you when you had a rip in the crotch of your pants last week,
and you needed me to sew it up?” she replied sweetly.
Dipper closed his eyes in mock resignation and set his book aside. “All right!”
he huffed.
Mabel squealed and flipped over, wrapping her arms around Dipper’s waist and
squeezing, while Dipper rested his arm across her shoulders and affectionately
stroked her hair with his other hand. She happily tilted her head up to look at
his face, and he smiled back at her.
For the last few months, the twins’ close bond had grown even closer. To an
outside observer, the playful banter and close physical contact between them
could have looked almost flirtatious, and in a way it was. The love and
attraction both twins felt for the other was stronger than ever, but they
tempered their actions just enough that their un-sibling-like feelings weren’t
blatantly obvious to see. They just came across as oddly close. Individually,
they enjoyed thinking about being more than brother and sister to each other,
unintentionally managing to make each other feel very desirable and aroused.
On the same wavelength, they both broke the embrace at the exact moment they
thought it might be getting too weird for the other. “So, what’s wrong?” Dipper
asked, now fairly well practiced in the flow of their evolving relationship
dynamic.
Mabel also pulled herself back together smoothly. “Dad says I can use this ‘HBO
GO’ thing on my laptop. So I can, you know, call up whatever I want, instead of
just … whatever’s on!” Dipper snorted at Mabel’s terminology, resulting in
Mabel lightly punching Dipper in the stomach. Quickly Dipper had the settings
configured, then sat back with his book as Mabel started scrolling through the
back catalog of TV shows and movies that were available.
“Man, there’s some stuff on here that lil ‘ol innocent me shouldn’t be
watching!” Mabel giggled.
Dipper perked up at that. “Like what?”
Mabel gestured at the screen. “Like ‘Game of Thrones’, for starters! From what
I’ve heard, it should be called ‘Blood and Boobs!’ Have you ever heard what
it’s about?”
“No,” Dipper lied. He actually knew exactly what it was about, and in fact had
secretly read all of the “Song of Ice and Fire” novels the show was based on.
“How did youhear about what the show is like?”
“Wendy told me a bit about it our first summer up north, but I really don’t
know very much about the story. She and her crew would sometimes watch it at
Thompson’s place,” Mabel replied. Her expression turned sneaky. “Wanna watch an
episode now?”
Dipper was torn. He was curious to see if the television adaptation was as good
as everyone said it was. But he had to be careful. They couldn’t get caught by
their parents watching this, and he’d also have to keep up the lie to Mabel
that he didn’t know anything about it. In addition, he was very aware of two
characters in the books named Jamie and Cersei Lannister, a pair of twins.
Seeing how they would be depicted, while watching with Mabel beside him, could
be exciting, or really mortifying.
He decided to take a chance. “OK, do it. I’m making sure Mom or Dad don’t see,”
he said as he got up to close his bedroom door.
Mabel started the first episode of the first season, the twins watching on the
laptop while lying on their stomachs side by side on the bed. Sure enough,
there was plenty of graphic gore and gratuitous nudity. Dipper squirmed with
embarrassment at watching this with Mabel, but he didn’t want to stop either.
As the episode drew to a close, the character Bran was overhearing sounds of
passion through an open window, and Dipper knew what was coming. Sure enough,
the Lannister twins were revealed as the source of the noises, with Jaime
taking his sister from behind
“And THERE’S the incest!” Mabel cried with mischief.
Dipper jumped, gaping at Mabel in disbelief as she paused the playback. “Oh
come on, Dipper! Everyone knows the twins on this show are gettin it on!” she
teased. “And so did you! I’ve seen those paperbacks under your bed! You knew
exactlywhat was going to happen!”
“Sorry,” Dipper said sheepishly, blushing. “But it’s a little … weird, I
guess.”
Mabel’s cheeks also darkened. “I think we can handle a little weird,” Mabel
replied, and Dipper swore her eyes twinkled. He returned the expression without
thinking.
With that, Mabel grinned and unpaused the video. The show quickly concluded,
and without hesitation they decided to call up the next episode.
===============================================================================
 
***** Winter 2014 *****
The twins and their parents got off the elevator in the lobby of the beach-
front hotel. The kids were in bathing suits, their parents were dressed in
comfortable shirts and shorts.
“You have your keycard?” their mother said to Mabel. She grinned and waggled
her shoulder bag that also contained her towel and suntan lotion. She bumped it
playfully into Dipper’s matching bag. “Good. Your father and I are going to
check out the casino further down the strip. You two go enjoy yourselves in the
pool and on the beach, but make sure you both leave time to go back up to your
room and change before dinner.”
The Pines family didn’t often splurge, but it had been a busy and successful
year for both of the twins’ parents. They decided the family could enjoy a trip
south to a Caribbean island resort for March break. It was a great surprise for
their children, who had never in their fourteen years been on a tropical
vacation.
Dipper and Mabel immediately headed outside to the hotel’s pool. The heat of
the sun and the cool of the water combined for a comfortable and pleasant early
afternoon as they played on the waterslides and splashed each other in the deep
end.
It was a great opportunity for Dipper to admire Mabel’s body. The one-piece
suit she wore wasn’t tremendously revealing, but it did nothing to hide her
developing curves. Dipper dove underwater often to get a clear, unobstructed
view, and really wanted to be able to slide his hands along her small but
feminine breasts, hips, and behind. Thankfully, the temperature of the water
was low enough that his penis didn’t advertise his admiration too noticeably.
But soon enough, they agreed that they had experienced as much fun as could be
had in the pool. “To the beach!” Mabel screeched, sending one last splash of
water at her brother before swimming quickly for the ladder. Dipper followed,
happily taking in the view of her backside as she pulled herself out.
As they walked to the ocean across the beautiful sand beach, Mabel continued
her own subtle appraisal of Dipper’s maturing physique. He was still skinny,
but muscle definition was also becoming noticeable in his arms, shoulders, and
mostly-hairless chest. She wished his swim shorts weren’t so baggy, so that she
could see if his ass was as cute as the rest of him.
They decided they wanted to see how the water was, but they had to set down
their bags. Looking around, Dipper didn't see anywhere they could safely leave
them unattended.
He saw a large group of at least three families with children, heading further
up the beach and carrying similar bags as the twins were. In that direction,
the shoreline curved out into the ocean and the sand piled up into a dune, so
that the section of beach beyond was hidden from the busy area directly in
front of the hotel. Ahead of the group, other beach goers were cresting the
dune and disappearing from view as they descended to the other side.
“Let's see where they're going,” Dipper suggested. “There might be places to
stash our bags there.”
Over the next few minutes as they strolled down the beach, the twins continued
their unconscious flirting with each other, the surrounding waterfront much
less important than spending time focused on each other. As they began climbing
the shallow slope of the dune, they failed to pay any attention to a sign that
was posted beside the path.
Mabel had just finished putting forward a funny theory on how Mermando’s family
might be from around the island, when they reached the top of the small hill.
“Uh ... Mabel?” Dipper said slowly. Mabel saw that he was staring at the beach
before them, and she also looked.
This section of the beach was less crowded, but there were still more than
enough people for the twins to see that this was a “clothing optional” beach.
At first, both of them were hit by the urge to immediately turn around and go
back: they were uncomfortable because they had never seen casual nudity before.
But then they noticed that none of the people were acting strange about it.
There were sunbathers and swimmers of all ages, from toddlers to seniors, all
enjoying not being encumbered by swimsuits. They noticed that there were
several teenagers that looked about their age, as well. No one was showing any
shame, regardless of how fit, or how out of shape, they were.
Mabel looked back at Dipper carefully. “You … wanna stay here?” she asked, not
sure of what she wanted to hear as a response.
Swallowing, Dipper was about to take the safe way out and turn around. Then he
locked eyes with his sister, seeing that she was trusting him to decide for
them.
He hoped he knew what he was doing. With a shy grin, he replied, “Sure … why
not?” Mabel’s face broke into a smile that surprised both of them.
They found themselves a spot on the beach that was not too near any other
people and spread their towels beside each other. For several moments, they
just sat there, glancing around at each other and at the sunbathers, but not
really looking. There were naked people in every direction, casually displaying
body parts that the kids had never seen in real life before.
“Dip, we’re … uh … kinda the only non-nudified people here,” Mabel said
quietly.
Dipper took a deep breath. “Then … let’s just do this?” he said, pulling the
drawstring to his swim shorts and pushing his thumbs under the waistband.
Mabel pulled the straps of her suit down off her shoulders, holding the garment
to her chest with her hands. Then she nodded. “Let’s do this!” she replied
bravely.
The twins lifted their butts, pulled down their suits to their ankles and
removed them, dropping the pieces of fabric beside them. Hugging their knees in
front of them, they were naked in front of each other for the first time since
they were probably two or three years old. After a quick awkward moment of half
glances at each other’s bodies, they managed to lay down side by side on their
stomachs, resting their heads on their arms and staring wide-eyed directly at
each other.
“This … is … cray cray!” Mabel whispered loudly.
“Yeah!” Dipper said in a hushed voice. “... Are you all right?”
Dipper’s protective concern immediately relaxed Mabel. “Yeah, I’m good, I
think.” She took a deep breath, a large smile of relief spreading on her face.
“It feels … really amazingto be naked out in the open!” she said as she
gleefully squirmed on her towel.
“Yeah … it does!” Dipper said, starting to grin as well. He surprised himself
with the truth of the statement. Dipper had always been the more self-conscious
of the pair, and he could only assume it was Mabel’s presence that was driving
him to so adventurous. To be naked! In public!He liked the feel of the light
wind and the sun, both now caressing his entire body. It was a very freeing
experience.
For the first few minutes the twins just talked, slowly getting accustomed to
being naked. People strolled to and fro past them, some heading to the ocean,
others just enjoying a walk.
Mabel had seen enough. Actually, she hadn'tseen enough, at least not enough of
Dipper. And taking the opportunity to let him see all of her? She wanted to do
it now. It was time to get off the towels.
“C’mon, Captain Cheese Dip,” she invited, lifting herself off her elbows and up
to her knees. Dipper had a perfect up-close view of the front of her body, and
he gulped involuntarily. She reached to grasp his hand. “Let's go try swimming
now!” She got to her feet, relieved that her brother didn't resist as she
pulled him upright, as well.
Before taking a step to the water, they took a moment to appraise each other's
bodies, but trying not to look too interested. Mabel thought Dipper’s
“dipstick” was fascinating: he had a sparse patch of hair surrounding the base
of a penis that wasn’t fully hard, but definitely wasn’t tiny, either. She
couldn’t help but admire it, and how cute it was when it and the sack behind it
swayed slightly with Dipper’s movements. Meanwhile, Dipper was trying and
largely failing to not to stare at his sister. The tiny bounces of her breasts
were wonderful, as were her perfect-looking nipples. What he could see of her
crotch was mostly just a light fluff of hair with a puffy slit beneath it. She
was as beautiful as he had imagined.
They didn’t even notice they hadn’t released each other’s hands. Dipper was
blushing as he rubbed the back of his neck. “You … look nice, Mabel,” he
mumbled bashfully.
Mabel’s blush radiated across her skin, as well. “Aw, thanks Bro. I … think
you’re lookin’ pretty fine, yourself.” Their gazes met again, and each saw the
same embarrassed grin that graced their own face. Mabel snorted, causing Dipper
to bark a small laugh, and the ice was broken.
For the rest of the afternoon, the twins hung out, with the same odd vibe of
seemingly oblivious attraction. Only now, they were nude, which ratcheted up
their emotions that much higher. Every touch, every glance was more electric.
As they swam and played in the ocean, hands and feet would “accidentally”
glance across each other's skin. Back on the beach, they helped each other
apply sunscreen where bathing suits had previously covered. Mabel confirmed
that Dipper’s butt was, in fact, very cute, and she shivered as she applied the
lotion for him. Everything was wonderfully exciting, quietly frustrating, and
very arousing.
Dipper in particular had difficulty with the obvious physical evidence of his
excitement, particularly as his earliest fantasies of him and Mabel together
took place on the beach of the “Blue Lagoon.” His penis was in a “mostly erect”
state all afternoon, his brain and body at war constantly over what condition
he wanted to present himself to Mabel. He made several clumsy, stuttering
attempts to blame his “condition” on the wind or just anatomical fickleness.
Although she was mightily tempted, Mabel sensed she shouldn’t make fun of him,
and gradually Dipper became more comfortable with himself being completely
exposed.
As dinner hour neared, the teens reluctantly put their bathing suits back on
for the walk back to the hotel. They both now agreed that the whole concept of
having to wear them sucked, but such was life.
“Well I'm glad we did that!” Mabel said, wrapping her arm behind Dipper's
slightly sunburned back and shoulder as they neared the hotel. “Another
exciting chapter in the New Adventures of the Mystery Twins!”
“Mabel!” Dipper groaned, cringing at the thought of anyone, particularly their
parents, learning that they enjoyed a nude beach together.
She laughed and poked him playfully. “And you know what? This is all practical,
too!” Mabel continued. “Now for the rest of our vacation, we don’t have to run
into the bathroom to change our clothes. I mean, what’s the point, after
today?”
Dipper didn’t want to disagree with that logic, but he had an immediate need to
have the bathroom all to himself: he desperately needed to relieve the
uncomfortable pressure that had built in his testicles all afternoon. There was
no way to explain his urgency, not without revealing that he had been so turned
on by her all day, he’d literally been in pain. How would that sound? No, he
couldn’t explain it to her at all.
Once in their room, he hastily grabbed his clothes and headed straight for the
bathroom. He brought himself to orgasm after only a few seconds of rapid
stimulation, washing away his first case of “blue balls” in a wonderful wave of
satisfied bliss.
However, that relief came at a price. Mabel thought he had changed his mind
about how cool it was to be so open with each other. Not wanting to push
things, and feeling like she should avoid embarrassing him further, she waited
until Dipper emerged from the bathroom, then she also used the privacy of the
locked room to change her own clothes.
He noticed her awkward change of attitude, and knew he was the cause, but felt
helpless to do anything about it. The end result was that the twins buried
whatever progress they had made that day in developing their relationship. For
the remainder of the vacation, they kept their distance in their hotel room,
and never suggested to the other to sneak off to the nude beach again, even
though privately they both wanted to.
===============================================================================
 
***** Spring 2014 *****
Going to the prom was a stressful enough event for any student at Piedmont
High. For some, it was not pleasant at all.
In general, Grade 9 freshmen were largely unattached, often still forbidden by
parents from going on dates until they were older. But that didn’t stop a lot
of young students from going anyways. Groups of boys and girls would gather
together, occasionally asking or being asked to dance by someone from another
group.
Mabel was similarly restricted from dating. She had no date to the prom, but
she decided to go anyways and be with “her people”, as she referred to her
small posse of oddball friends.
It seemed like she was having a good time. Because she was outgoing and was
always hamming things up in classes, she enjoyed a kind of popularity at
school. She certainly wasn’t one of the cool girls: instead, her upbeat
attitude and always-friendly demeanor made her approachable to “normal” boys.
She didn’t lack for dance partners as the night went on.
But Mabel was growing more and more upset with every moment of the prom. All
around her were couples, happily enjoying the evening together. There were kids
developing new feelings. And from some of the boys she danced with, she saw
signs of genuine affection. Some of them kind of likedher.
And Mabel was having none of these emotions herself. Not for anyone at the
prom, anyways.
Dipper had stayed home, saying he wasn’t interested. Mabel had half-heartedly
tried to get him to go, but secretly she was glad he didn’t. She didn’t know
what she would do if she saw some other girl approach her brother and ask him
to dance, or even worse, if he'd asked some other girl himself. And she’d have
had to resist asking him to dance herself, because at prom, that would be very
strange. But now Mabel missed Dipper. And it hurt her to realize that the boy
she wanted to do all these “prom”-y things with was the boy that she couldn’t
ever have that happen with. She got more and more down in the dumps as the
evening went on.
Their mother had volunteered to pick up Mabel and her friends from the school,
dropping them all off and finally arriving home after one in the morning.
“But you had fun, didn’t you?” the twins’ mother said as she unlocked the door
and entered their home.
Mabel shrugged. “There was lots of romancin’ goin’ on, but none for me!” she
griped.
Her mother tsked and squeezed her shoulder. “Oh, Pumpkin! We think you’re too
young to have a boyfriend yet,” she said as they climbed the stairs to the
second floor. “You’ll be ready to start dating boys in the next little while, I
think. In the meantime, you shouldn’t stress about it.” She nodded to the light
peeking out from beneath her brother’s bedroom door. “Dipper stayed home. He
had the right idea. Looks like he’s still up. Say goodnight to him before you
turn in, okay?” Her mother kissed her cheek and went into the master bedroom,
closing the door behind her.
Mabel paused before she could tap on Dipper’s door. Did she want to see him at
that moment? Wouldn’t that just be the final stake through her chest? To see
everyone else able to act on matters of the heart wasn’t enough? Dipper being
her brother reinforced why she couldn’t act. She’d fallen in love with someone
who she could never have. To face him now was too much! She turned around,
ready to just collapse onto her bed.
Dipper’s door opened as she crossed the threshold to her room. “Hey,” he said
quietly. “I thought I heard you co- ….” His voice trailed off as Mabel went
into her room without turning around, and starting closing her door. Dipper
leapt forward and held it with his hand. “Mabel, what’s wrong?” he asked,
concern evident in his tone.
“Nothing, Dip,” she grumbled. Still, she allowed Dipper to follow her in.
He carefully closed the door behind him. “Mabel, it’s not nothing,” he said.
“You didn’t have a good time at the prom?”
Mabel sat on her bed and flopped unceremoniously onto her back. The frilly
spaghetti-strap prom dress splayed out, much as her arms did, as she stared at
the ceiling. “Using those mad investigation skills to figure that out ...
Inspector … Dip-adget?”
A tiny smile crossed Dipper’s mouth. “That was the worst play on words I’ve
ever heard from you.” Then his face turned sympathetic as he sat down beside
Mabel on her bed. “Now I know you didn’t have much of an evening. C’mon Mabes!”
He reached over half-heartedly to tickle her kneecaps. “Out with it.”
Mabel was in too fragile a state to play her usual “affection game” with
Dipper: she was afraid her true feelings would spill out, She batted away his
fingers, then covered her face with her hands. “I can’t, Dipperrrrrrrr,” she
groaned.
She heard Dipper’s voice harden. “Did something happen at the dance?” he asked.
“Did someone do something to you? I’ll-”
“No, Dip,” she interrupted, “nothing happened.” His protectiveness, the way he
cared about her, made her love him more than ever. Why did he have to be her
brother? Why couldn’t he be someone who could feel the same way for her that
she felt for him? “I’m just … it’s me! I’m too … weirdfor all this romance-y …
prom-y ...  poop!” she mumbled through her palms on her face.
“Yeah,” Dipper replied solemnly. “I know how that feels.”
The tone of his voice poked a hole in Mabel’s shield of self pity. She dropped
her arms and looked up to Dipper, who was just staring at his ankles as he sat
beside her. He looked just as down as she felt. She kicked herself for not
seeing it, for giving in to her old selfish tendencies. Regardless of her own
down-in-the-dumpiness, and that he was the reason for her mood, it wasn’t his
fault. Her broski looked like he needed some old-fashioned TLC, and darnit, she
would buck up and give it to him!
Mabel sat back up and turned towards Dipper. “C’mere,” she said as she wrapped
her arms around him. “Dippin Dots needs hugs!” She pulled him close and nuzzled
her head into his neck, inwardly knowing she wanted this just as much as she
thought Dipper needed it.
She sighed happily when Dipper didn’t hesitate at all. He immediately returned
the hug and rested his cheek against Mabel’s ear.
There was a long moment that neither twin moved. Mabel wasn’t even sure how
much time had passed. She only knew that she was more at peace than she had
been for a long while. Without thinking, she twisted her position to get more
comfortable, pressing her breasts into Dipper’s chest as she reapplied her
squeeze.
For a split second, Mabel feared Dipper would freak out at this. But instead,
he also shifted to accommodate, burrowing his face into her hair. They were
sharing the most snug, intimate embrace she had ever experienced.
Everything Mabel had been feeling for two years, all the pressure she felt on
her heart from the prom, overflowed in that moment. She couldn’t stop it, and
she didn’t want to stop it. She had to let out what she desperately wanted to
say.
“I love you Dip,” she whispered.
She felt his muscles tense, and instantly Mabel feared the worst. He was
creeped out! He was disgusted! For what seemed like forever, they were frozen
in the hug. She opened her mouth to explain away the words, to say that she
didn’t mean it that way, when she heard Dipper’s tentative whisper in reply, “I
… love you too!”
Mabel felt Dipper take an uneven intake of breath. Slowly she pulled her head
back so she could see his face. The instant she saw the look of fearful
longing, the quivering lower lip, the wide, moist eyes … the moment he released
a shuddering sigh ... all doubt was gone. Though their mouths were only an inch
apart, Mabel wanted to dive forward, lest the moment slip away.
And she was delighted when Dipper beat her to the punch. He leaned in and
kissed his sister for the first time, a kiss that she returned passionately.

***** Summer 2014 *****
“So … here we are!” Dipper said nervously after closing the attic door.
Mabel stood close to Dipper. She twisted her hair in her fingers, a habit that
gave away that she was a bit anxious. “Yup! … Right here!”
Dipper took a step forward, his right hand vigorously scratching the back of
his neck. “Are y- … are wesure we wanna do this?”
Touched by her brother's concern, Mabel felt her worry melt away. She took a
deep, confident breath. “Yeah, Dip. I am!” She reached behind his head and held
his hip in her other hand. One look into her brother’s adoring eyes, and all
doubt was gone. She wanted this!
Mabel smiled, attempting a seductive tone. “I … hope you are, too.”
His sister’s self-assurance was exactly what Dipper needed to hear. “Yeah!” he
whispered dreamily in reply, leaning his head down carefully from his slight
height advantage to kiss her.
A week had passed since their first kiss. In that time, the twins had kissed
many more times, and had explored and confessed their feelings to each other.
The night of the prom, they were still uncertain. They had kissed
enthusiastically, but then as they clumsily laid down on Mabel's bed, the
spaghetti straps on her dress snapped, exposing her breasts as the top of the
dress fell down. They both awkwardly agreed that it would be best if Dipper
were to return to his room, even though they had seen each other naked just a
few months before. Later they would talk about how they both felt, that
everything could have spiralled out of control. And with their parents just
down the hall, they were likely correct shutting things down on that first,
incredible night of discovery.
In the days that followed, both of them were still insecure, wondering if their
twin would start feeling sick about what they were doing. Neither could be sure
that their dream wouldn’t still revert into a nightmare.
They could scarcely believe it, but they came to realize the dream was true!
Slowly they revealed to each other how they had felt for so long. Tears flowed
as they quietly stole away brief moments together, making a connection they had
denied themselves even the hope of ever happening.
However, such moments were brief, and very scarce. Final exams needed to be
written the whole week following the prom, so they needed to study. Their
parents were around, of course. And they had to get packed, as they were
scheduled for a third summer in Gravity Falls, and they would leave the weekend
immediately after exams. They barely got to second base together, and the whole
time they were afraid of getting caught, and terrified to ask the other just
how far they wanted to go with this new relationship.
It was on the long bus ride north that the twins finally had time to talk. They
were both elated, and somewhat scared, to admit to one another that they both
very much wanted to do more together. Much more. As in “all the way” more!
But if that was actually going to happen, they agreed they needed protection.
They could not act foolish. At a rest stop on the bus ride, a red-faced Dipper
tried to sneak nonchalantly into the washroom, where he purchased two condoms
from the vending machine. He was certain that every person present in the
restaurant was staring at him and judging him for what he planned to do with
his sister.
Now the two of them were alone in the attic of the Mystery Shack late that same
night. They knew that they wouldn’t be disturbed, since Soos said he was busy
fixing a display case and Melody was occupied feeding their infant son.
Dipper had to break their kiss to pull the condoms from his pocket and drop
them on the night table between their single beds. Then they quickly fumbled
with buttons and zippers, all the while kissing all over their sibling’s face
and neck. The pent-up desires of the past week drove them to dispose of their
clothes as rapidly as possible. As they stood naked and close to one another,
they looked each other up and down unabashedly.
“You're so beautiful,” Dipper whispered, tentatively running his hand through
Mabel’s long hair and across her shoulder, while his eyes bounced up and down
between her face and her breasts.
Mabel’s breath caught as she lightly dragged the fingers of both hands down
Dipper’s chest, then across his flat stomach to his waist. She gripped his skin
and drew herself a half-step closer, leaving only a few inches between them.
“You’re pretty handsome yourself!” she breathed in reply.
Their lips touched again, and their bare bodies came together. Mabel’s naked
breasts pressed tantalizingly against the skin of her brother’s chest.
Fingertips and palms first caressed shoulders, waists, and backs, then moved to
hips, breasts, and butts. Dipper’s very erect penis poked between Mabel’s legs,
the top of his shaft nestling its way into her folds as the twins panted
unsteadily into and around each other’s mouths. Their pelvises began grinding
together, seemingly of their own accord.
One of Dipper’s hands moved around from Mabel’s behind to slide between their
bodies. Palm facing his sister, he reached down to explore between her legs.
His middle finger found the top of her slit and he moved it down an inch, right
into the wondrous hot and wet channel, and over a small bump. Mabel gasped and
her eyes squeezed shut, her body clenching at Dipper. He wasn’t sure if this
was a pleasant or painful reaction. “Are you okay?” he verified, supporting his
sister’s body with his free hand while holding his finger immobile.
“Yeah!” Mabel breathed in reply with a nod. Dipper decided to try that bump
again, and he slowly drew his finger up and back down, completely overwhelming
her. “Oooooo yeeeeeaaaaaaah!!” she moaned, one hand clutching tighter behind
his neck while the other reached to grasp Dipper’s penis for the first time.
She had just enough brain power to command her hand to pull on it up and down
next to her vagina as she rode through the wonderful stimulation on her
clitoris.
Dipper tensed and groaned as well. “Oh god!” he gasped in pleasure, setting his
finger to work on that magical button he’d found.
The twins fingered and stroked each other to ever-increasing levels of arousal,
pressing their mouths together to stifle the passionate noises they were
making. It didn’t take long before Dipper’s whimpers grew louder and higher
pitched as Mabel’s pants and gasps became deeper and throatier. Finally, Dipper
winced hard, an almost pained expression on his face, and Mabel felt his penis
throbbing as warm semen splashed on her thighs. An enormous orgasm of her own
took hold, Dipper doing his best to hold her as they both rode out their
intense first sexual moment together.
Basking in the afterglow, they moaned quietly and gently continued kissing as
they came down from their fervent high. When their lips finally parted, Mabel’s
eyes fluttered open to find Dipper staring dreamily at her in loving amazement.
“Wow!” he said in a low voice, a small smile spreading on his blissful face.
Mabel thought he looked adorable. She pushed herself up onto her toes and
kissed Dipper’s nose. “Boop! Ya mushy nerd!” She giggled, releasing her grip
from his rapidly-softening penis, then pulled back a bit to survey her legs and
fingers. “Eww! You’re a messy nerd!” she exclaimed with a grin.
Dipper blushed despite their intimate position together. They didn’t have a
towel nearby, so he grabbed his t-shirt off the floor and shyly helped Mabel
wipe up.
“Well! Now that that’s out of the way …” Mabel declared, she pounced on her
brother, knocking them both back onto his bed. “I declare Cuddlin’ Time!” she
murmured into Dipper’s ear as she rolled off him and onto her side. Dipper
turned to face her, and their arms and legs naturally wrapped around each
other. They squeezed each other tight, then relaxed with satisfied sighs, still
in each other’s embrace.
For several minutes, the twins lay together side by side, comfortably on top of
the covers in the warm night air, noses almost touching, slowly caressing one
another’s skin as they whispered how much they loved each other, and how long
they’d been waiting to be with one another. Dipper chuckled as he recounted how
he had overheard Mabel getting herself off in that very room the previous
summer on their first night returning to the Shack.
“Oh yeah? Well F-Y-I, Bro Bro, I seem to recall some serious personal time
activity goin’ on in this bed the very next night!” Dipper reddened again,
immediately aware of the event in question. “You remember what you were
thinking about that time?” she teased in an exaggerated sultry tone.
“Every moment,” he replied, immediately serious. His palm brushed hair from her
face, and his hips made a small, unconscious thrust. “The two of us were
stranded on a desert island. We were alone, just us … we were on the beach-”
“Was the sun shining?” Mabel asked, grinning and clamping her eyes closed.
Dipper closed his eyes as well as he remembered his fantasy of the Blue Lagoon.
“Yeah. Warm, but not too hot. A nice cool breeze, too.”
“Hmmmm!” Mabel hummed happily, squirming closer, rubbing herself onto Dipper’s
body. “The sounds of waves crashing, lots of birds crying, too!”
“That smell of sea salt coming from the ocean,” chimed in Dipper with a smile,
getting into the imagery in his head, his hand sliding down Mabel’s ribs
towards her hip.
Mabel giggled as she rolled her pelvis into him. “That crazy feeling of your
brother’s thingpoking against you!” Dipper bashfully opened his eyes to find
Mabel already giving him a saucy stare. “We were lying on our sides? Like we
are now?”
Dipper shook his head slightly. “I was lying back ... you were … on top of me.”
“Oh. Like this?” Mabel murmured as she pushed herself off the mattress and
carefully slid herself over Dipper, pushing him over onto his back. She
straddled him at his thighs, his fully recovered erection pointing up at her
chest, then she leaned forward and wriggled up his body. Dipper’s penis was now
trapped against his stomach, and he gasped as his testicles and the underside
of the shaft rubbed along Mabel’s vagina as she moved up his body. She ground
against his length repeatedly as she leaned down to Dipper’s aroused face. “Is
this more like it?” she asked teasingly.
“Uh huh!” Dipper managed to reply, his hands gripping lightly on Mabel’s
smoothly gyrating hips. “You’ve … almost got everything right!”
Starting to breathe harder again, Mabel smiled, eyeing the condoms on the night
table. “Almost, huh?” she panted and she continued moving. “What am I not doing
right … I want it to be as … perfect a recreation as possible!”
Dipper swallowed, a hand moving quickly up to Mabel’s cheek. His face turned
pleading. “Mabel … “ he whispered. “Please … just let me know this is … this is
what you really want!”
Mabel felt spontaneous tears spring into her eyes. She slid her own hand up to
her cheek and gripped his hand. “Yes, Dipper,” she replied sincerely, no hint
of joking in her voice. “I love you! I’ve wanted this for a long, long time!”
“I love you so much!” Dipper breathed. Then he reached over and snatched one of
the condoms. Mabel watched in amusement, continuing to grind on Dipper’s groin,
as his shaking hands struggled to tear open the foil wrapper. After he managed
to extract it, he looked at it obtusely, trying to concentrate through the
distraction Mabel was giving him lower down. “I’ve … never used one before …I’m
not sure …”
“I’ll help!” Mabel chirped excitedly, taking the disc and sliding back down
Dipper’s body. He watched, nervous and excited, as Mabel held his penis steady
and placed the condom on the tip. Dipper felt her warm breath on his member as
she moved her face close. They both watched, fascinated, as she rolled the
condom down his length.
There was a small problem: the condom was obviously too large. They looked
doubtfully at the latex sheath draped loosely over Dipper’s fourteen-year-old
penis. “Oh well!” Mabel declared, her smile covering up any concern that might
show on her face. She scrambled back up, holding Dipper’s covered erection to
her virginity with one hand and his shoulder with the other.
She lowered herself down until she felt Dipper’s tip notch into the entrance of
her vagina. Then she let go of the shaft and leaned forward so she and Dipper
could watch each other’s faces. “Here we go …” she whispered, hiding her
nervousness as she began to bear down.
As she pushed down, nothing happened at first. She felt Dipper pushing up at
the same time, increasing the pressure. Mabel bit her lower lip. Then some of
the friction was suddenly overcome, and over an inch of Dipper’s length
penetrated at once. Mabel couldn’t mask her discomfort as she was stretched
painfully.
Immediately relaxing his pelvis, Dipper’s hand went to her face. “I’m hurting
you!” he said, alarmed.
Quickly wiping her eyes, Mabel said, “No, I’m okay! I’m fine! Let’s keep
going!”
Being a virgin, Mabel didn’t know she really wasn’t prepared to have sex. She
was tight and a bit nervous, neither of which make any girl’s first time easy.
Between herself and the rubber, there was too much friction for their coupling
to go smoothly. And Dipper wasn’t free of discomfort himself. Being unfamiliar
with condoms, the twins had no idea that he was supposed to pull back his
foreskin prior to rolling on the rubber. The loose sheath was now folding up at
the tip and pulling the foreskin down over the head as he entered Mabel. The
delicate, normally protected skin of the head began rubbing tightly against
folds of latex without any lubrication.
Mabel was determined that she would show Dipper the full amount she loved him,
even if this hurt her a bit. Impulsively deciding that the “ripping off the
band-aid” method was the best way to go, she took a deep breath and dropped
down with all her weight.
Both twins cried out in pain. Tears ran, uninhibited this time, down Mabel’s
cheeks. Dipper clenched his teeth to keep from shouting as the bunched up
condom dragged across the exposed tip. She gingerly lifted herself back off,
the condom coming loose and yanking off of Dipper’s penis, stretching and
rubbing at the sensitive head again as it came away. This caused another
exclamation of agony that Dipper muffled with his own hand. Mabel was sitting
beside him now, doubled over trying to deal with the awful experience of a
deep, unlubricated first-time penetration.
Soos’ voice called up from the bottom of the stairs. “Hey dudes! You all
right?”
Dipper took a deep breath. “Yeah Soos!” he yelled. “I just … stubbed my toe!
I’ll be fine!”
“What about Hambone?” Soos continued. “I swore I heard Mabel scream, too?”
“It’s okay!” she shouted shakily. “I … I stubbed my toe, too!” Dipper gave
Mabel and incredulous look. Mabel shrugged back helplessly.
“Woah, random number theory! What’re the odds?” Soos called back. “Ya want ice
packs, or anythin?”
“We’re good!” they yelled back together.
The twins spent the next few minutes recovering, getting over the panic, pain,
and embarrassment. At first they had trouble looking at one another, now
uncomfortably naked, not feeling at all sexy. Dipper turned his head away while
Mabel held her shins in an invisible Sweater Town position.
Mabel shifted, inhaling uncomfortably as the nerve endings in her crotch
protested. Finally, she broke the silence. “Guess that coulda gone better,
huh?”
Dipper snorted derisively. “Yeah, you think?” He rolled over away from Mabel to
hide his face and his sore and completely flaccid penis. “I’m sorry,” he said
softly after a short silence.
“I'm sorry too,” Mabel mumbled. Then a moment later, she smirked and put her
palm on Dipper's hip. “And sorry to Mr Dipstick, there!” she chuckled softly as
she slid her hand down to try to tickle his genitals.
Still upset, Dipper squirmed and pushed Mabel's hand away. “Mabel, I hurtyou!
How can … how can you even want to touch me again?” he said bitterly. “I wish
that … I’m just sorry we did all this at all!”
“Hey!” Mabel replied, caressing his arms and back. “I'm not sorry about that! I
mean ... yeah, that really didn't live up to the harlequin romance level first-
time experience there, but we experienced it. Together! I would never have been
able to handle having anything like that happen with anyone else!” Dipper still
faced away, but he was no longer trying to avoid her touches. “The Mystery
Twins will figure this out! And then next time, it'll be way better!”
Dipper rolled back towards Mabel, tearful astonishment clearly evident on his
face. “Next time?” he asked weakly. “You … still want there to be a next time?”
“Well, not tonight, for sure!” she said, laying her head on her brother’s chest
and hugging his torso. “But you're not goin’ anywhere, and neither am I! You
can bet your super-adorables little butt there's gonna be a next time!”
A relieved and thankful Dipper finally returned the embrace, placing a long
kiss to the top of Mabel's head. She made happy, satisfied noises in return.
“I love you so much,” they said in unison, causing them both to smile even
wider.
===============================================================================
 
There was indeed a next time. Many more next times, in fact.
The following day, their first full day since arriving in Gravity Falls, Soos
gave the twins the whole day off to rest from their long travel day. Mabel got
to help Melody take care of little Stan Jr, while Dipper and Soos drove to town
to pick up supplies. Afterward, they were given the full tour of the extensive
renovation Soos had given to the Shack. Business had been so good, all the
available space in the building was needed for new displays and attractions.
Soos had built a large addition onto the back of the building, providing new
living space for his growing family and himself, plus an apartment Grunkles
used when they were home between adventures.
The only space in the older part of the structure that Soos could not adapt for
tourists’ use was the attic, so it was left to be the domain of the twins for
whenever they felt like coming up from the city. And for the remainder of the
summer, the isolated attic provided a perfect, very private place at night for
Dipper and Mabel to physically explore their new romantic relationship.
That night, Dipper showed Mabel the lubricant and “snugger fit” condoms he’d
managed to buy in town when Soos wasn’t looking. They fooled around, giggling
as they practised putting the rubber on the correct way, getting more
comfortable and relaxed. The following nights they experimented with more
touching and fingering, then with oral sex.
By the weekend, they felt they were ready to try intercourse again. This time
all their preparation and practice paid off, and they both had a very
pleasurable, loving experience.
For the remainder of the summer, Dipper and Mabel couldn't imagine their lives
could be better. They had fun and interesting jobs, money in their pockets, no
commute time to or from work, the best landlord and boss in the world,
occasional visits by their favorite great uncles, and most importantly, the
freedom to love each other almost without restriction. Dipper had to return to
town often as the weeks went by: his visits to the pharmacy for “supplies”
actually increased in frequency as time went on.
As August came to a close, their return trip to Piedmont loomed. Their last
night in Gravity Falls was bittersweet, as they made love tenderly, but
despairing that their hedonistic summer was done. They would be home for their
fifteenth birthday on Sunday, then school the next week, but none of that
seemed important at all. They snuggled and fell asleep together on Mabel’s
small bed, as they had done most nights this summer, for the last time.
===============================================================================
 
The bus ride home provided the twins hours of uninterrupted time. There were
few other travellers on the coach with them.
Mabel was chattering happily about seeing Waddles and Mittens again,
reacquainting with friends, and even about starting school once more. She
talked rapidly, nearly nonstop. Meanwhile, Dipper brooded and said little,
holding Mabel’s hand and lightly running circles over and over into her palm
with his thumb.
Then their eyes met, and in an instant they both knew they couldn’t avoid it
any longer.
“Mabel …” Dipper asked softly, “... what’s going to happen to us?”
She squeezed his hand back, still smiling. “Hey, Chip Dip, don’t worry! We’ll
make this work, we … just have to be a lot more careful, making sure Mom and
Dad aren’t around, I guess …”
Dipper shook his head. “No Mabel, not that … I mean, yeah we need to talk about
that too … but …”
Mabel saw the worry on her brother’s face. “But what?”
He averted his eyes. “Let's say we're careful. And lucky. Mom and Dad don't
notice. We manage to hide this from everyone at school.” He paused, then
continued. “How long will it be before we make a mistake? How long until our
luck runs out?”
“I …”Mabel started, but found she didn't have an answer.
Continuing to stare at the back of the seat in front of him, Dipper went on.
“Maybe we somehow get through high school. What then? Do we go to college
together? Can we keep hiding this from everyone if we do that?”
Mabel knew now that this had been bothering Dipper for some time. She waited
with trepidation for him to finish.
“So we go to college. We get our degrees. Then what? … How do we hide then? …
We can’t ever get married, we can’t ever be normal, we can’t ever have-”
Dipper’s voice cut off.
She looped her arm around his back and pulled him to her. “Dipper, whatever
games of hidin’ and seekin’ we need to do, we can do it! We’re still the
Mystery Twins, figuring weird junk out!”
“Or …” Dipper’s voice hitched. “... or what if … one of us doesn’t want to keep
hiding? That keeping this secret just gets to be so much … y- one of us starts
thinking it’s not worth it ...”
Mabel heard the slip in Dipper’s explanation. He was afraid she would break up
with him when it became too difficult to continue masking the truth of being in
a secret and forbidden relationship. That he thought she would dump him when
the going got tough.
“Dipper Pines, look at me!” she interrupted.
Reluctantly, Dipper turned his head towards his sister. He knew he was in
trouble, that she had heard that he thought she would be the one to break
things off someday.
But instead of anger or hurt, he saw nothing but affection and sincerity on her
face.
“I love you, Dipper. I’ve known that for two years, but now I can say that, in
a way, I’ll have loved you fifteen years tomorrow! You are more to me than
anyone else ever could be!” She placed her hands on his cheeks. “We were born a
pair, and we’ve always had each other. I know that I never, ever want to you
lose you!” She felt tears running between her fingers. “I want to be with you,
no matter what! Maybe we have to be sneaky, maybe we tell Mom and Dad someday,
maybe we let the whole world know they can kiss our cute matching asses … I
can’t imagine what my life would be like without you, Dipper, and I never want
to find out! Get that into your big ol’ brain! Okay?” she cried quietly, her
cheeks now as moist as her brother’s.
Dipper sobbed loudly while reaching out to grab Mabel, desperately pulling her
to him. They cried openly as they hugged and kissed with fervent need, uncaring
if anyone around them was watching. They might not have all the answers of what
lay before them, but both of them now knew that they were committed to face the
challenges ahead together. They were in love, and that was all that really
mattered.

***** Part 5 - Perfection *****
*****   *****
===============================================================================
***** Autumn 2014 *****
The twins were laughing and jostling on the couch while playing Super Smash
Bros. It was a Saturday evening in November, and they had been playing most of
the day after picking up the game on its release day the night before.
“Dipper? Would you please come up to your room?” called down their mother from
the top of the stairs.
Mabel controlled Sonic, and was on the verge of defeating Dipper’s Mario, but
he had just landed a combo to increase her damage past 90%. “Just a sec!”
Dipper called back without taking his eyes from the big screen television.
“Right now, please!” came the stern reply from their mother.
Dipper froze at the tone of voice, and Mabel immediately commanded Sonic to
finish off Mario with Sonic’s Smash Attack, ending the round. Already thrown
out of sorts by his mother, Dipper threw a death stare at his sister as he rose
from the couch. “Really?” he grumbled.
Mabel looked back with a guilty smile and performed a weak pump of her fist.
“Boo ya?” she replied quietly.
Rolling his eyes and dropping his controller on the sofa, Dipper headed up the
stairs, taking them two at a time. When he arrived at his room, his mother was
standing in the hall, directing him inside. As he turned, he noticed his father
seated in his desk chair, waiting. Nervously, he sat on his bed as his mother
closed the door.
His father leaned forward. “We’ll get right to the point, son,” he said,
raising his hand from where it had been resting palm down on his lap. Dipper’s
eyes widened in shock as his father presented him with the nearly empty box of
condoms that had been hidden in his desk drawer. Then his chest constricted in
near panic as his mother reached to the floor to pick up Dipper’s trash bucket.
He noted most of its contents had been emptied, and he knew exactly what he’d
be seeing: latex sheaths that had been quite clearly used for their intended
purpose.
Dipper immediately assumed that it was all over: his parents knew about his
relationship with Mabel! They would split the twins up, they’d send him to
juvenile prison, they’d disown him, they’d castrate him, they’d- … Dipper’s
brain short-circuited from all the terrible things he imagined was about to
happen in the next few seconds. He began hyperventilating in panic.
“Whoa, settle down, Dip!” said his father. He rolled the chair forward and put
a calming hand on his son’s shoulder.
His mother knelt down to eye level. “It’s okay, Dipper! Your father and I just
want to talk with you. Don’t pass out on us here, okay?”
Enough logical thought remained in Dipper’s brain to realize that his parents
would not say “it’s okay” if they knew that their children were having sex with
each other. He forced himself to try to calm down as his father continued to
hold his shoulder.
“Look Dip,” his father said gently, “we’re just a little concerned over why
you’re … practising … with these condoms so much.” He released his grip on his
son and scratched the back of his head.
“You’re only fifteen, Dipper,” his mother continued, her voice authoritative,
but concerned. She steadied herself before she could go on. “Are you …” She
closed her eyes. “Are you already sexually active? Have you been out having sex
with someone?”
Dipper realized that he had a chance to get out of this. He just needed to be
convincing: he had to lie straight to his parents’ faces, and he wanted to make
it believable. They could not be allowed to guess the truth. But he was
mortified and frightened.
“No.” he answered simply, mumbling and avoiding eye contact with either of the
adults in the room. “I’ve never had sex.”
Dipper’s mother knew him very well. Her eyes narrowed. “You’re sure?” she
asked, suspicion obvious in her voice.
“Yes, Mom!” he responded with earnest embarrassment, face red. “I’ve never …
you know .... ‘been’ with anyone … I mean, jeez Mom, I’ve never had a
girlfriend or even close to one … you know, it’s like Dad said …” he moaned,
waving at the bucket of evidence, “... practise … by myself … that’s all!” he
finished, cringing pitifully.
After watching his face for a moment, his mother’s face relaxed. “All right,”
she relented. “I’m sorry, Dipper. It’s just that … I know that we haven’t
talked a lot about this, but … you know that your father and I both waited for
one another, right?”
The only thing worse for Dipper than talking with his parents about him having
sex was talking with them about his parents having sex. Dipper’s skin darkened
even more. “... Yeah?”
“I know here in the city, in this day and age, things are different than they
were for us when we were young,” she said, gripping her husband’s hand. “It was
easier for us to not get all drawn in … for us to be a little more innocent, I
guess?”
His father cleared his throat. “This isn’t news, but your mother and I both
came from pretty strict homes, Dipper. Your Grandpa Shermie made sure I was in
church every Sunday. We had no unchaperoned dates, the whole old-fashioned
deal. I actually asked your grandfather for his daughter’s hand in marriage
before I asked her!” Dipper rolled his eyes, as he already knew this and really
didn’t want to talk about it. “Yes, it was out of date for me to do that, even
then. That was only seventeen years ago.” He squeezed his wife’s hand. “We were
both virgins until we married. And again, yes, we know how unusual that was
then, and certainly how rare it is now!”
“But there’s something to be said for saving yourself!” Dipper’s mother
interjected. “We just … want you to know that you don’t have to … have sex with
a girl just because you like her. You don’t have to be in such a hurry!” Then
her face relaxed and she chuckled softly. “I know, I know … hormones make
things so hard! I have to admit … if we weren’t chaperoned ... “ she began to
show a blush of her own, “... I daresay we might not have made it to our
wedding night as virgins, either!”
“Oh god!” moaned Dipper quietly, his chin on his chest.
Dipper’s father looked amused at his son’s discomfort, then he sobered. “Son,
we can’t stop you from doing what you want. If … if you’re planning on being
sexually active, well … using a condom is exactly the right thing to do.” He
stopped to nudge Dipper, and the teen reluctantly lifted his head to face him.
“We just ask you to consider what we’re saying here. There’s a difference
between just having sex, and making love! I’m sure you may find that sex would
feel great. But when it’s not just sex … when you don’t squander your one
chance you have, to be able to experience making love with someone you just
know you want to be with for the rest of your life … it’s … it's simply the
most incredible feeling you will ever know!”
How could Dipper tell his parents that he already understood exactly what his
father was saying? He swallowed hard, willing himself not to show any of the
emotion that struggled to escape.
“We love you, Dipper,” said his mother, “and we’re sure this was not the
conversation you wanted to have. Just please think about what we’ve told you,
okay?” Dipper nodded in reply, and his parents both gave him a kiss on top of
his head as they left his room and retired to the master bedroom.
Heart still beating like crazy, Dipper slowly made his way back down the stairs
to the family room. When she saw he was alone, Mabel leaped to her feet and
grabbed his hands.
“I couldn’t make any of that out, but that sounded kinda intense!” she
whispered urgently. “What happened?”
Dipper wrapped his arms around his sister, and he immediately started feeling
the pressure release as she squeezed him back. Quietly he replied, “They found
my condoms.” He felt Mabel tense, and added, “It’s okay, they don’t suspect us.
But …they were kind of disappointed that I had them. I made them think I was
using them to practise, and now they think I want to sleep around!”
Mabel snorted, relaxing and pulling back to smirk at her brother. “Dipper, you
big ol’ slut!” she teased, cuffing him on his shoulder.
“Not funny!” Dipper groaned, keeping his arms around her waist. “This is kind
of serious, Mabel! They’ve pretty much made it known that they still don’t like
the idea of either of us thinking about sex before marriage. So now, what’s
gonna happen if they find I’m still using condoms? The ‘practise’ excuse is not
going to cut it again! They’ll start wondering exactly why I’m still using them
here in the house, and then they might go looking in your room, too!”
“That … would not be so great!” Mabel deadpanned.
Dipper held her tighter. “I love you, Mabel. Nothing will ever change that! But
without the condoms, we might not … we might not be able to … make love
anymore!” Dipper was on the edge of tears with the thought.
Mabel brought her hands to Dipper’s face and turned his head towards her, her
lips quickly seeking his out. After a long, comforting kiss, she used her
thumbs to wipe his tears, and murmured, “Maybe …” and then with a crafty look,
she continued, “... maybe not!”
===============================================================================
 
The following Monday, Mabel began her monthly period. It had never been an
altogether pleasant experience, but she had never raised much of a fuss in the
past, either.
However, this particular month Mabel complained much more about the severity of
her cramps. The pain was excruciating, she wailed. Wasn’t there something to be
done about this? She couldn’t deal with this discomfort!
An urgent appointment with the family doctor was quickly made. After listening
to Mabel’s description of her pain, the doctor diagnosed Mabel as having
dysmenorrhea. The easiest treatment for the symptoms, she explained, was to be
on a daily regimen of COCP, a combination of estrogen and progestogen which
reduces the intensity of the monthly cramps.
The medication’s more well-known prescribed usage, of course, was that of being
an extremely effective method of birth control, and was commonly called “the
Pill.”
They left the doctor’s office, Mabel with the prescription script in her hand.
They got into the car and headed to their pharmacy.
“Mabel ... “ her mother said as she steered her way through the suburban
traffic, “you know what most people use these pills for, don’t you?”
“Mom!” Mabel groaned, blowing her breath through her lips dramatically.
“I’m just saying, please be … discreet! All right? I understand you need them
now, and that the Pill is the best way handle your pain. But don’t let everyone
in your school know you’re on them, please. Kids will talk, and word will get
around. Some young people will get the wrong idea about you.” She glanced
worriedly at her daughter. “Your father and I know that you’ve wanted to start
dating for awhile now. Maybe after Christmas, we’ll see how it goes. But if you
have a reputation, if everyone knows you’re on contraceptives … you might get a
lot of unwanted attention … and get pressured to do things you might want to
think about … saving.”
Mabel blushed brightly, embarrassed and extremely worried that her mother would
ask her directly if she had ever been active sexually. She had never been able
to lie to her mother effectively, and she doubted today would be the day she
would acquire the skill.
Her mother sensed her discomfort as they waited at a traffic light. “We don’t
have to do this now, but we need to talk about these things. How about we agree
to hash this out the next time you ask me when you can start dating?” She
smiled sneakily. “Maybe I can keep you my little girl just a wee bit longer!”
She turned her attention back to the road as the light turned green.
Mabel saw that her mother cared for her daughter’s well-being as well as her
daughter’s reputation. “Okie Dokie!” she replied with an over-the-top pout,
making her mother smile wider.
Inside, she felt guilty for misleading her mother, but still relieved that her
plan had worked out. Having to keep condoms hidden wouldn’t be an issue for
Dipper or her much longer.
===============================================================================
 
It was the morning after Thanksgiving, and the twins’ parents had left to see
what “Black Friday” specials could be had. Their father had asked if the kids
wanted to come, but they had declined. Their mother told them to fix turkey
sandwiches for lunch, and not to expect their folks to return until late
afternoon. Dipper and Mabel managed to wait ten minutes after being left alone
before they were certain the car wouldn’t come back into the driveway. Mabel
commanded Waddles to stay, then grabbed Dipper’s hand and they tore up to her
room. Urgently, they clutched one another and smothered each other’s mouths
with kisses.
“Oh Mabes-” Dipper gasped desperately. “-I’ve missed you-” kissing her again,
“-so much!”, recalling their private conversation where she told him they had
to wait until after she started the pills, and for her period to finish, before
they could try intercourse again. The medication had arrived in plain brown
packaging on Wednesday. Two days later, this had been their first chance to be
alone.
Mabel moaned loudly, loving the feeling of Dipper’s mouth on hers, his arms
around her, one hand in her hair and the other squeezing her butt. “What's
s'matter?” she teased. “Can’t handle-” “-Mabel deprivation-” “-for even-” “-
a week?” she giggled between kisses. Her own hands moved over Dipper’s body
sensually.
Panting, Dipper pulled his lips away, moving his palms to the sides of her head
and gently weaving his fingers into her hair. He kept their noses and foreheads
pressed together. “I don’t think I can handle Mabel deprivation ever again!” he
breathed, eyes less than an inch away from hers, wide with love and devotion.
His chest almost hurt from the effort of trying to communicate the intensity of
his emotions to his sister.
Mabel’s insides did that melty-squishy thing that they always did when Dipper
would say something earnest and passionate about how he felt for her. Her hands
slid up to his cheeks, caressing the edges of his ears, eyes, and mouth with
her fingertips and thumbs. Her every sense was filled by her brother, no other
distractions invaded.
“I love you, Dipper,” she squeaked.
“I love you too, Mabel,” he whispered back. The twins melted together again,
gradually lowering themselves onto her bed.
Neither of the teens had changed from their sleepwear that morning: ridding
themselves of their sleeping shirts and underwear took very little time at all.
They moved as one, rubbing their nude bodies together as they clutched onto one
another tightly. Their fingers and mouths tickled and probed each other, their
foreplay quickly escalating the level of their arousal.
Mabel rolled onto her back and pulled Dipper on top of her between her legs.
“No need to unroll onto the pole,” she growled as she reached between them to
grasp his penis.
Dipper shuddered as he allowed Mabel to lead him to her vagina. She guided his
tip to her clitoris, allowing him to rub her button deliciously along his
length with several pushes of his hips. Then as he pulled back for another
lunge, she aimed him lower. He sank all the way into her in a single stroke.
“Oh god!” Dipper groaned. “This feels … so much better!” He instinctively began
slowly thrusting, completely lost in the delight of the warm and wet friction
on his member.
Mabel quivered, feeling ecstatic shocks of pleasure. She loved the spontaneity,
the lack of needing to stop everything for a condom. And without the rubbery
texture, Dipper felt smoother inside her, almost like velvet. The sensation of
his slow, careful movements was phenomenal.
The twins were experiencing complete and total intimacy for the first time. The
final barrier between them was at last removed. They gazed at one another in
wonder, almost shocked with the indescribable feeling of completion.
Then the dam broke. Dipper’s mouth crashed down onto Mabel’s as she used her
arms and legs to squeeze his body to herself as securely as she could.
Unashamed moans and cries of passion accompanied the sounds of creaking
bedsprings and of skin slapping together rapidly. Nothing mattered now except
helping each other reach their peak together. After only a minute or so of
frantic lovemaking, they desperately held each other tight and cried out loudly
as they both climaxed. They had never felt closer or more love for each other
than at that moment, as Dipper’s penis delivered his semen unimpeded to his
sister's cervix.
Teenage exuberance helped them make love four more times that day before their
parents came home. They made each time last longer than the time before, and
they were happier than ever with their sex life. It wasn’t just the feeling of
complete closeness: the lack of latex made Mabel feel less dry than she had
experienced before, and Dipper had far more sensitivity. They both came to the
conclusion that although not using a condom was a bit messier, there was no
doubt that they would never use one again if they could help it.
===============================================================================
 
***** Part 6 - Conception *****
===============================================================================
***** Winter 2015 *****
Dipper was in his room, packing his bags. Lightweight shirts and shorts joined
several books and his new tablet in the suitcase. He also packed his swimsuit,
smiling knowingly to himself at how little he hoped it might be worn in the
coming week.
It was after dinner on Friday night, and the family was preparing to leave the
next morning to go south for March Break vacation again. In fact, at Dipper and
Mabel's suggestion, their parents had booked a week at the same hotel as the
year before. The twins had made sure to let their mother and father know how
much they had enjoyed themselves the previous year, and had no objection to
returning to the same resort.
The teenagers had been quietly thrilled when they learned they were going to
the resort a second time. Surely they would have the opportunity to sneak away
to the nude beach again? And a hotel room to themselves! It was stressful to
spend any pleasurable time together in the house: even on the occasions their
parents left them alone, they always worried that they might be caught by
anything that could bring their parents home early. At the resort, they would
have six nights of total privacy! Dipper hadn't had any opportunity to fall
asleep in Mabel's arms since the previous summer in Oregon. And that was in the
uncomfortable single beds in the stuffy attic of the Mystery Shack, a far cry
from high-end queen-sized beds in an air conditioned hotel room. Dipper was
pumped for this to be the best vacation possible!
“Dipper?”
Hearing Mabel's voice, Dipper turned around to his open bedroom door, a beaming
smile already spreading on his face.
His smile faded instantly when he saw his sister's grim expression. He rose
from where he was seated on his chair and crossed quickly to the door where
Mabel stood. “What's wrong?” he asked under his breath, aware of their parents
downstairs. When Mabel didn't immediately answer, he guided her into his room
to sit her on his bed, and closed his bedroom door.
Kneeling in front of Mabel, Dipper put a hand on her knee and the other on her
cheek. She looked ill, and terrified. “Mabel! Talk to me! Tell me what
happened!” he pleaded.
Mabel bit her lower lip, clearly trying to not burst into tears. She raised a
shaky hand, holding a narrow plastic stick. She turned it to hand it to Dipper
by its handle. In confusion he took it, examining the markings.
His heart skipped a beat as he realized that he was holding a pregnancy test
device. Then it felt like his heart stopped altogether.
The test result window clearly indicated a positive test result!
Dipper felt the shock rip through him, as he let the device fall to the
carpeted floor. “Oh my god, Mabes!” he rasped. “Are you sure? I mean … the test
could be wrong, couldn’t it?”
She shook her head. “Dip … I haven’t had a period since December!” She paused
for a shuddering gasp. “I thought at first maybe it was the birth control pills
messing up my cycle ... but I’ve been having weird cramps, I’m tired, I need to
pee all the time, my boobs are kinda tender … it all says the same thing, Dip!
The test just proves it!“ She swallowed hard. “... I’m preggers!”
“But how?!” Dipper almost demanded. “You’ve been on the Pill! Haven’t you been
taking them every day, like you’re supposed to?”
“Yes, Dipper!” Mabel shot back defensively, her voice breaking. “Every day! And
I wondered the same thing!” She sniffled, hurt that Dipper didn’t trust her.
Wiping her face with her sleeve, she continued, “So I looked something up a few
minutes ago. You remember that infection I got just before Christmas? You know,
the one ...” she tilted her head, gesturing lower on her body, “... down  there
?”
Dipper was confused. “I guess? ... But obviously we didn’t ‘ do’  anything
while you had that! What’s that got to-”
“Yeah, well I took antibiotics to get rid of that infection,” his sister
interrupted. “And I was feelin’ fine after a few days, but I was told to finish
the whole bottle. I took those meds every day for two weeks! All the way
through the holidays!” The volume of her voice dropped. “... And according to
the papers with those drugs, it turns out … that stuff turns my ‘baby nope’
pills into ‘baby maybe’ pills,” Mabel grumbled miserably.
Dipper felt his heart sink, recalling that he and Mabel had found the
opportunity to make love practically every day after she’d started feeling
better over the two week break from school.
“Mom picked up the meds,” Mabel continued quietly. “And even if she knew,  of
course  she didn’t tell me this could happen. Why would she?” Her face
crumbled, and she took an unsteady breath. “But  I  should’ve read those
papers! This is … this is all my fault!” she sobbed.
“No, Mabel!” Dipper whispered urgently. “ I  should’ve known! I’m the one who
likes to read stuff like that … maybe we might have held off, or I could’ve
worn a condom …” he babbled as his panic rose. “I mean … this is more  my
fault than yours! If I hadn’t been so scared of getting caught with the condoms
in the first place, then …  it’s just … Mabel,  what are we gonna do?!? ”
“ I don’t know!! ” she squeaked in reply, nearly hysterical. “I  can’t  … and
we can’t … and if …”
Dipper immediately forced himself into analytical mode. It was hard, since he
wanted to try to comfort Mabel, but he could feel himself starting to
hyperventilate. Only arriving at a solution mattered now, so he pushed aside
his panic and personal feelings. “Okay, okay! We’ll figure this out! Just …
just let’s settle down and go over our options.”
Mabel sniffed, wiping her eyes. She trusted Dipper to help them stay strong
together. “... Okay.”
“All right,” Dipper said, thinking quickly. “Option one. We tell Mom and Dad,
and-” he screwed up his face doubtfully, “they help us figure out what to do?”
“Dipper, they’ll be furious! What will they say? What will they  do  to us?”
“I know, Mabel. But we’ve got to think of everything we  can  do, and pick the
one that’s the best choice. Okay?” Mabel nodded reluctantly. “Option two. You
…” he avoided looking at Mabel, “... get an abortion.” He felt sick as he
suggested it.
Mabel cried softly into her hands. “I … I don’t know if I can do that!” she
weeped. “Before I came in here … I’ve already thought about that … but after
spending the summer with little Stan Jr … it’s just  not the baby’s fault! ”
Dipper nodded grimly, but had to move on. “Option three … we run away. Both of
us.”
“How would  that  work?” Mabel almost barked. “We’re  fifteen , Dipper! Where
are we gonna go?”
“... Gravity Falls, maybe? Move in with Soos and Melody?” he suggested weakly.
Mabel again buried her face in her hands as she considered the possibility that
everyone they knew in Oregon, including their great uncles, would find out
about them. “I don’t know, I’m just thinking here!” Dipper cried.
“Yeah I know!” Mabel said pitifully. Then she peered up at Dipper again. “Any
other options?”
Dipper shuffled, looking very uncomfortable. He knew there was one option left.
A really bad option. One that was  permanent , an option that there was no
coming back from.
He considered it quickly, and immediately despised himself for it.  No , he
thought,  I will NOT suggest to my sister that we could kill ourselves! Surely
it could never get bad enough for that! I won’t LET it get that bad!
“No,” he answered quietly after a lengthy pause. “Those are the only three
possibilities.”
“What about raising the baby? What about giving it up for adoption?” Mabel
asked desperately.
Dipper shrugged apologetically. “Both of those decisions come after we choose
between telling Mom and Dad, or running away. It’s still one or the other. Or …
or abortion ...”
Mabel balled her hands into fists and brought them down hard on her thighs. “Oh
Dipper, I hate myself for this … but … what do  you  think we should do?”
He sighed heavily. “Well, there’s only one option that doesn’t completely
change our lives … but …”
“... but we’d have to …  kill  our baby …” finished Mabel, her voice barely
audible.
“I don’t like it either, Mabel,” admitted Dipper. “It’s the  easiest  option.
We sacrifice the least. And … it  is  your body, so … you don’t  have  to go
through with this ...”
Mabel stared unfocused and silent for over a minute. Finally, she slowly shook
her head. “I can’t,” she whispered. “I can’t kill our baby … I just can’t do it
…”
Dipper carefully leaned forward and hugged Mabel tight. He would never have
tried to convince her one way or the other. Dipper believed that the decision
to abort her pregnancy or not was her, and only her, right to make. He wanted
to her to know he supported her choice fully.
“Then, we have only two choices left,” he said as he continued to hold her in
his arms. “We tell Mom and Dad, or … or we run.”
The twins talked and cried for over an hour after that. Running away only made
sense as an option if they intended to keep and raise their child. Did they
want to do that? Would they be able to hide the truth of the baby’s father?
Even if they could, were they prepared for the accusing looks and nasty
comments that Mabel would face for having and raising a child while so young?
Would Mabel ever be able to get a normal education?
But if they chose to give the baby up for adoption, what then? Could they bear
to have their baby taken from them, knowing the life they’d created together
was out there in the world, without them?
And putting aside all these other questions, would the baby be healthy, given
its incestuous conception? Could Mabel and the baby receive good medical care
during her pregnancy?
Facing all these questions helped focus the two choices they faced. Finally,
they decided which path they needed to follow. They kissed each other deeply
and whispered words of love and devotion to one another, confirming that they’d
always been there and would always be there for each other. No matter what.
Twins forever.
===============================================================================
 
“Dad?” said Dipper carefully from the threshold of the door to the study, where
his father sat typing at his computer.
“Hey Dip!” replied his father. “Just finishing up some office work. Stuff’s got
to get done before I can leave for a week.” He swivelled in his chair to face
his son, glancing at his watch. “It’s getting late. You almost finished
packing? You know we have to get up early.”
The teenager shuffled awkwardly. “Yeah. Can you just come out to the couch,
please? Mabel and I … we need to tell you something.”
The elder Pines raised an eyebrow. “That sounds ominous!” he said.
Dipper didn’t respond, he simply headed to the living room to join his sister,
who was just arriving with their mother in tow. He knew his father was
following behind him.
“Mabel, I’m very busy,” their mother was saying. “I was late getting back from
dropping Mittens and Waddles off at their pet sitters. I don’t want to be up
all night packing.” Mabel convinced her to sit on the sofa, where their father
joined her. “So what is this all about?”
Mabel sat down on the love seat that faced the sofa, and Dipper sat next to
her. They looked at each other nervously, nodded, then Dipper spoke. “Dad? Mom?
You’ve always said we should just get to the point, right? That we’re just
wasting time otherwise?” Both parents verbalized their agreement. Dipper looked
back to Mabel.
She paused, took a deep breath. “I’m pregnant,” she said, her voice betraying
the terror she felt.
Both parents drew a sharp intake of breath. Mabel cowered instinctively and her
hand sought out Dipper’s. He took her hand without hesitation and squeezed it
hard, drawing strength from Mabel as much as he lent strength to her.
He took a deep breath of his own. “And I’m the father,” Dipper said, his voice
cracking.
Never let it be said that Dipper and Mabel’s parents weren’t fine people. They
loved the twins, and worked hard to provide for them. They were old fashioned,
but willing to grant that their kids might not want to follow their traditions.
So given the double nuclear bombs that their two children had just dropped on
the family in a five second span, they took the news about as well as could
have been expected.
But that doesn’t mean it still didn’t get ugly.
===============================================================================
 
***** Part 7 - Parturition *****
***** Autumn 2015 *****
Dipper leaned across to the older student's textbook. “So you can determine the
linear function which takes value f of a at a, and f of b at b, by this
formula,” pointing at an equation, “because the first term is 0 when x is b and
is f of a when x is a, while the second term is 0 when x is a and is f of b
when x is b.” He paused, searching for comprehension in the face of the
teenager beside him. “Understand?”
The young man beside him wore the jacket of the Westfield High football team.
He looked back dumbly. “No, man! This calculus shit is hard! You gotta slow it
down, okay?”
Inside, Dipper screamed in frustration at this idiot's lack of even basic
intelligence. Outwardly, he smiled politely. “Okay, no problem. Let's see if I
can explain it another way…”
Since he’d showed up as a newcomer to the mid-sized New Jersey town at the
beginning of summer, Dipper had gained a favorable reputation as an excellent
tutor. He worked long hours over July and August with teens requiring
assistance with their remedial summer classes, and now with regular schooling
resumed, he worked afternoons and evenings as well as all day on Saturdays.
The jock was Dipper's last client of the day. The town’s library, which didn't
seem to mind if he used it as the base of operations for his tutoring business,
just announced closing time in ten minutes, meaning it was almost nine o'clock.
Dipper yawned, dreading his own homework which he had yet to touch.
His cell phone buzzed, and he glanced at the screen. And suddenly he was not
tired at all!
“Sorry gotta go no charge for today's session bye!” Dipper spewed as he hurled
his books into his bag. Seconds later, he was out the library doors into the
late September evening, on his bicycle, and pedaling home as fast as his legs
could get him there.
===============================================================================
Mabel reflected on all that had happened over the last several months. The
memories flew by in a rush.
The emotional trauma of that night in March when she and Dipper had confessed
to their parents. How it had taken hours between the yelling and crying to
explain what had happened between her and her brother over the last year, and
the feelings over the years before that led up to their relationship. How they
made their parents at least begin to understand that their love, wrong or not,
was genuine. And how Mabel was determined to keep the baby.
The week that followed. Their vacation cancelled. Endless accusations and
demands, outbursts and pleading. Negotiation. Questions. Research. And finally,
reluctant agreement on a plan, a plan of action for the whole family.
The remainder of the school year. Bulkier sweaters than usual. Suppressing the
nausea. Uncomfortable deflection of questions from friends about the upcoming
summer. Stealthy packing of belongings on weekends and after school.
Moving out of the only home she and Dipper had ever known at the end of June.
Moving to a smaller house in a new town across the country.
Continuing to grow ever bigger throughout the summer. Learning the skills
necessary to be a parent. Laughing ironically at the way she waddled like her
pet pig. Complaining about the pains in her back. Crying about how inadequate
and unprepared she felt.
She and her brother’s sixteenth birthday. Celebrating quietly and
uncomfortably, no one but the four of them in the house. Sharing a brief kiss
under their parents’ watchful, disapproving eyes.
Registering for school. Enduring the silent scorn of the other students. Lying
about the parentage of the baby, telling anyone who cared to speak to her that
the father was in California.
Watching Dipper labouring harder than ever before in his life. Working to be
financially supportive. Working to continue to get top grades in school.
Working to learn how to be a great father. Always working, tirelessly.
The strange experience of feeling her water breaking the previous night.
Texting Dipper to come home immediately. The entire family rushing to the
hospital as she began to feel contractions.
The pain. The unbelievable pain! The patient, soothing words of encouragement
and support from her brother, whom she wanted as her coach. The unintentional
hilarity of seeing him almost pass out as the delivery reached its climax.
All these memories flashed by in an instant, all the hardships now undoubtedly
worth it. As she lay exhausted on the delivery room bed, with her brother
hovering by her side, she was holding an incredible, tiny, brand-spanking new
person in her arms! Their daughter. She and Dipper had made a beautiful,
perfect little girl!
===============================================================================
The following evening was a Thursday. Dipper knew Mabel and the baby were
discharged from the hospital after lunch some hours before, but he had been at
school and then the library all day. Excited, he bicycled home as quickly as he
could, arriving home shortly after nine.
Dipper’s father, as per usual since their move to the east coast, was busy in
his basement office with late-night work. His mother was also home, emerging
from the laundry room after doing the first of what would be hundreds of loads
of clothes and towels in the coming year. Dipper gave Waddles a scratch behind
the ear, before finding his sister in the house’s modest living room, sitting
in a rocking chair and breastfeeding their infant as she hummed a lullaby.
She lifted her head as Dipper came in. She looked haggard and dead tired, her
hair a tangled mess, and not a trace of makeup. And she smiled at him.
He swore to himself that she had never looked more beautiful!
Dipper heard a soft snort of suppressed amusement beside him. He turned to see
his mother was smirking at his awestruck face, recognizing that look of
hopelessly complete love. Then her expression softened, and she tilted her head
towards Mabel. He smiled gratefully to his mother, then quickly padded over to
his lover and daughter.
His mother watched the young couple and their child, a war of emotions within
her.
After finding out about Mabel’s pregnancy, she and her husband had eventually
respected Mabel’s desire to keep the baby. But they knew they couldn’t just
leave their children to be exposed to the terrible treatment that would surely
come, once the neighborhood and school found out Mabel was pregnant. In
particular, they anticipated that there would be rumors that perhaps Mabel’s
strangely-close twin brother was the father, rumors that would be impossible to
disprove. The innuendo and shaming would have been horrific, and legal
authorities might even have gotten involved.
Their father had been granted permission from his tech company to quickly
transfer from the San Francisco head office to a branch office in Newark, but
he regularly was required to be available on west coast time for additional
assignments. Their mother closed down her real estate business in Oakland, and
was taking a hiatus from trying to begin again in New Jersey until Mabel and
the baby no longer needed her. For the sake of protecting their children, both
parents had given up or damaged their career paths, leaving the family with
much less money and a far more uncertain retirement plan.
The twins’ father quietly climbed the stairs from the basement and hugged his
wife from behind, resting his chin on her shoulder and also taking in the scene
before them. The twins were oblivious to their presence. To their parents,
Dipper and Mabel looked like any young couple in love.
But few couples had to deal with their circumstances. The decision to keep the
baby had also forced Mabel and Dipper to sacrifice greatly. Their parents had
forbidden Mabel from even considering dropping out of school, as so many teen
mothers do. The local school board was piloting a program that gave teenage
mothers four weeks of maternity leave from high school attendance, provided she
continue to complete school work at home. After this, Mabel would return to
school every day while her mother cared for the baby, an arrangement her mother
agreed to for a year. After that, the child would need to have daycare, and
that needed to be paid for. Two years of school and homework while raising a
baby was a formidably difficult plan.
Earning extra money was Dipper’s sacrifice. To ensure that he lived up to his
responsibility as the child’s father, he would have to work long hours in
addition to school. All his earnings were to go into paying for the baby’s
needs and health care costs, costs that were not covered by their father’s
benefit package. Anything left would go to savings to pay for future daycare
expenses. He had no reluctance for this, but he did have some regret that he
would not legally be the baby’s father. The documents would be registered with
the father listed as “unknown”, and he admitted that it would be less
complicated for the child if she were to officially be just his niece. They had
plenty of time to decide how they would tell their daughter about her parentage
when she got older.
The final sacrifice was the hardest to accept: the twins were forbidden by
their parents any physical intimacy. This was non-negotiable for their parents,
regardless of how strongly Dipper and Mabel felt for each other. For their only
children to be sexually active together was simply unacceptable, a mistake that
would not be permitted to be repeated. Beyond “normal” brother and sister
behavior, they would only be allowed short kisses on the lips, and only when
the teens were at home. The parents promised very unpleasant punishment if they
ever found out this rule had been broken, not the least of which would be the
loss of any chance of restoring trust in their kids. They did, however,
acknowledge that if the twins still felt their unnatural romantic attachment to
one another after a year of parenting, they would grudgingly revisit this issue
at that time.
Ultimately, both twins had accepted the terms laid out. They agreed they had to
show their parents that they were serious about their child, and about each
other. If their parents could give so much up for them and their well-being,
and allow them to remain under the same roof even after such a colossal error
of judgement on their part, they could withstand the challenge. They promised
to take this “mistake”, and make it into something wonderful.
The twins’ mother held tight to her husband’s arms as they watched the scene
across the room. Then she turned her head to peer at his face. He looked back.
She wordlessly communicated a simple question with a sideways glance of her
eyes and a sympathetic expression: Maybe, just this once, we could give them
some time to themselves? After a brief pause, he gave her a small smile and a
nod.
They gave one last long look at their children and grandchild, then turned and
went to their bedroom.

“She’s amazing!” Dipper whispered in awe as the infant suckled on Mabel’s
breast.
“Yeah!” Mabel replied quietly. “I can’t believe just how amazeballs she really
is!”
They watched in silence for another minute as the baby appeared to have taken
enough. She coughed, then began to cry. Mabel pulled her shirt back into place,
threw a towel over her shoulder, and gingerly lifted the squawking little human
up to her shoulder, giving gentle pats to her back. Mabel laughed in delight as
the cries were interrupted for a second by a large burp, and a substantial
stream of milky spit flowed out of the baby’s mouth onto the towel. She then
resumed crying, somewhat less urgently now.
Obliquely, Dipper couldn’t believe how happy he could be while wiping up baby
puke! He smiled stupidly while studying the little girl’s features and running
a finger delicately through her wisps of thin, wavy brown hair, and then
lovingly caressed her forehead with his thumb.
Soon enough, the infant’s cries grew weaker as the milk settled into her
stomach. Mabel supported her head and pulled her down onto her back, cuddling
her securely in her arms. The baby made a big yawn, accompanied by an adorable
squeaking sound, and fell asleep within a minute.
“We’re gonna be just fine!” Mabel murmured to the baby as she carefully stood
up with her precious bundle. “You’re absolutely perfect! I’ll try to keep
remembering that as you get bigger!” she giggled softly.
Dipper chuckled. “And you’ve got no idea how awesome your Mommy is,” he said as
he embraced his sister from behind and nuzzled her neck while gazing down on
their child, unconsciously duplicating the same position as their parents from
minutes before.
“I am pretty awesome!” she agreed, addressing her baby. “But your Uncle Dipper?
He’s just heckin’ ridonkulous! He’ll be all the Daddy you willever need, I
guarantee it!” She turned to look playfully into her brother’s face, their
cheeks pressing lightly against one another.
He held her body closer and longingly stared into her eyes. He tried to speak,
his mouth opening and closing twice, and his eyes becoming wet.
“I love you, Mabel! … So, so much! More than ever!” He looked apologetic at the
inadequacy of his words.
Tears began flowing down Mabel’s face as she reached for his lips with her
mouth, and as they kissed, Dipper slid around to face her. He held them both,
the two most important things to him that had ever existed. He felt giddiness
and warmth unlike ever before, as he and the love of his life kissed, with
their sleeping child nestled between them.
As their lips parted, Mabel whispered, “I love you, too, Dipper.” They rested
their foreheads together happily and admired their innocent daughter.
“And as for you, little one,” Mabel said softly, leaning down to kiss the
baby’s forehead, “you need to go to bed so we can do our homework!” Dipper
reluctantly released his hold, then felt his heart jump as Mabel motioned for
him to take the baby. Ever so carefully, they moved the infant from her
mother’s arms to her father’s. After a brief moment, Dipper was followed by
Mabel into her bedroom where the baby’s crib was waiting. After duplicating the
forehead kiss, he carefully laid the sleeping baby down on the soft mattress.
She didn’t wake up, and the teenagers were both satisfied with his efforts.
Finally, Dipper reached down and again lightly touched the baby’s forehead. He
smiled once more at the subtle birthmark, faint but unmistakable. Five dots
that perfectly replicated the constellation Cassiopeia.
“Goodnight, Cassie,” he murmured dreamily.
“We love ya, Baby Cass,” added Mabel in an adoring whisper.
The twins straightened up, verified the night light was on, and then took each
other's hands and made their way out to the dining room to begin their
homework.
