A/N: This is a kinda side story that takes place between Gravity Falls: Reboot and Invictus. I'll explain more after the story… try and suffer through it :-)

Dipper's wrists burned as he worked the rough ropes that bound his wrists. He needed to get out and fast. He could feel the heat of the large fire under the massive wrought iron cauldron that he assumed was meant for him.

The tiny creatures, about three feet tall, danced around the pot, chanting prayers to their gods. They looked like living Tiki masks with grass skirts. They were in a jungle clearing in front of various grass huts. On the one hand, Dipper and his sister did find a new species of polynesian creature. But, he's going to die by their hands.

"Mabel!" Dipper screamed. "Tell them to let me go!"

Mabel sat on a high throne and adorned with feathers and decorations. The Tiki-men had chosen her as their Moon-goddess, and he was going to be a feast in her honor.

"I tried, they won't listen to me!" Mabel said. "I'm sorry I got us into this mess!"

"Okay, it's going to be okay." Dipper said and strained against the ropes.

"We never should have come here!" Mabel cried. Dipper looked up at her tear stained face. The dancing flames bathed it in a warm glow. If he wasn't going to die a horrible death, he'd say she looked stunning.

A large flower bound her hair to the side. She still had on her floral bikini from the beach. The Tiki-men adorned her with flower necklaces and had been providing her with various food offerings. She did look like a goddess.

Dipper shook the thoughts out of his head. He needed to escape, not have weird thoughts about his sister before he gets boiled alive. He was regretting leaving the girls in Hawaii to go Mystery Twining on Tiki Island.

The chanting and dancing sped up as the drum beats increased. Mabel looked frantic as she tried to talk to some of the Tiki-men. Dipper worked the ropes the best he could. His wrists burned when he felt something wet fall on his face. He looked up with a smile, blood. Working the bleeding wrist, he was able to coax out more and was able to get enough to use as lubrication. With a jolt, his hand was free. He put it back up and worked the other hand loose. There was still the matter of his legs.

Dipper looked over to Mabel and nodded to her. She understood his look and stood up.

"Let's dance!" She shouted and began to flail about in her own Mabel style dance. The Tiki-men looked up in astonishment, and began to copy her. One of the guarding Tiki-men dropped his spear and ran over to join in. Dipper reached down and grabbed it, and cut the ropes on his feet.

With a sigh of relief, he stood up and popped his back and neck. The Tiki-men were still distracted by Mabel's hula dance. Dipper snuck up behind the chief struck him the butt end of the spear, rendering him unconscious. The Tiki-men looked to Dipper in stunned silence. Dipper removed the Tiki crown and kicked the unconscious creature into the crowd. He placed the crown on his head in defiance.

"I am your king now!" Dipper shouted. "Does anyone want to challenge me?"

Mabel clapped in glee as the Tiki-men bowed down to him. Mabel ran into Dipper's arms, he grabbed and spun her around as she embraced him.

"How did you know that will work?" Mabel said. The drumming resumed, and the Tiki-men danced in front of them. Tiki-men placed a multitude of food offerings in front of Dipper.

"It's simple really, most island cultures are ruled by the king. Whoever has the ornament of authority is the ruler. I take the crown, it means the king is incompetent and the wearer is the best person to rule." Dipper said.

"What's going to happen to the old king?" Mabel asked.

They both turned to the boiling pot of water and gasped in horror as the old king was unceremoniously dumped into the pot. The boiling water woke him up and he flailed about screaming as the Tiki-men lowered the massive lid over him.

"I guess… they eat him." Dipper said. Mabel's face squished up in a grimace.

Dipper sat down in front of the throne. He was too big to sit in it, but he still had to show authority. Mabel sat down on his lap.

"So… I'm the Tiki-goddess, and you're the king. I say we turned the tables on them." Mabel giggled. "So what now? We got back to the boat?"

"I'd like to explore the island some." Dipper said. "We did come here for that. I think now that we've got some friends… or loyal subjects. Maybe they can show us around."

"The girls are going to be worried." Mabel said. "It is pretty late."

"It's too dark to go back to the mainland anyway." Dipper said. "I'll radio in first thing in the morning to get a message to them."

A group of Tiki-men moved up to Dipper and Mabel and tugged on their hands. They lead them out of the main village and through the woods.

"Where are they taking us?" Mabel asked. Dipper shrugged.

"Best we just play along." Dipper said. Mabel nodded and took his hand. Dipper strained to see past the foliage in front of him. The Tiki-men spoke to each other in their unknown language. The jungle brush cleared and Mabel gasped at the view.

They stood in front of a clear blue grotto. Twin waterfalls cascaded down into a pool of the clearest blue. Dipper could make out various fish swimming inside. Bio-luminescent algae carpeted the bottom, casting an blue glow on the surrounding cliffside. Tiki-torches lined the edge of the water, allowing enough light to see where to walk. At the base of the cliff was a large grass hut, big enough for their size.

"Oh… my god." Mabel whispered. "This is the most beautiful thing I have ever seen."

"I think that's your house." Dipper said, pointing to the hut. "They work quick."

Mabel pointed to the opposite side of the grotto.

"Looks like they are starting to build yours." She chuckled. Dipper saw a flurry of activity. Tiki-men were building a second hut that was Dipper sized. Mabel walked to the shore and dipped her bare foot in. "Dipper, it's warm!"

"Mabel, this place looks sacred, I don't think they want you swimming inside it." Dipper said. Mabel ignored his protest and put her other foot in. She waited up to her thighs and was about to dive in when the Tiki-men ran forward in protest.

"See?" he said. Mabel walked over to them as they hopped up and down. She knelt down in front of them and the removed her flower and other ornaments.

"Oh they just don't want me to get their things wet." She said. One of them grabbed her bikini top and pulled. Mabel was able to dodge the tiny hand. "Hey!"

"Told you, it's sacred… I guess if you want to swim, you have to be all natural… goddess." Dipper said with a chuckle. "Oh well….what are you doing?"

She gave Dipper a coy grin turned her back to him. Her lithe body glowed in the fires, outlining her supple frame.

"Mabel…." Dipper said. To his horror, she pulled the bikini string, and let go. It seemed to take forever to tumble to the ground. Dipper's eyes locked on to the falling fabrics, his mind screamed a hundred thousand protests, but nothing registered. Mabel slid off the bikini bottoms and revealed her stark naked body to the clear blue waters before her and dove in. The Tiki-men gathered her clothes and trinkets and rushed them over to her hut to put them away.

Dipper could hear his heartbeat in his ears. Mabel broke the surface of the water and flung her long hair back in an arc. She was grinning ear to ear as she swam up to the edge of the lake.

"You going to come in?" Mabel asked.

Dipper kept trying to focus on something other than his naked sister. She seemed to enjoy his discomfort and splashed him.

"Oh come on, we used to take baths all the time," Mabel said. "Stop making it weird."

"We were like… kids then." Dipper stammered.

"Suit yourself…" Mabel said, swimming back to middle of the grotto. "I'm sure if Wendy were here you'd be the first one to strip down."

Dipper sighed. He knew Mabel was never going to let him live this down. Dipper stripped off his clothes and was down to his underwear. He looked over at Mabel. Only her eyes were above the water. She looked like a hungry crocodile… waiting for her prey to enter the water.

"Can… can you turn around at least?" Dipper pleaded. Mabel shook her head no. Dipper sighed and gave up. He freed himself of his shorts and dove into the grotto. Mabel was right, it was warm. He splashed her and swam to the center, trying hide his self conscious attitude. His Tiki subjects gathered his clothes and moved them to his half constructed home.

Mabel swam up behind Dipper and draped her arms around him.

"It's like this place was meant for us." She whispered. "The twin waterfalls. It just feels like us."

Dipper nodded, the more he was here, the more he didn't want to leave. He looked at his wrist and saw the rope burns were completely healed!

"Mabel!" He said, and held up his wrist. He itched all over.

"Dipper!" Mabel gasped. The water was glowing even brighter. She spun him around and held his cheeks to look at her. She took off his eye-patch and eased him underwater.

His whole body itched, his eye burned, and he felt like he was going to suffocate. Mabel brought him back up and wiped away the water over his eye.

"Oh… my god…" she said. Mabel held out her hand. It was full of the scar tissue. "Open your eye Dipper"

Dipper had been so used to the eye-patch, whenever his damaged eye became exposed, he held it shut without thought.

Dipper eye opened. The soft glowing colors of blue and orange bombarded the healed retina. The first thing his healed eye saw was the beautiful Tiki Moon-goddess. Dipper couldn't believe it, the water fixed his eye!

Mabel lunged forward and embraced him. He could feel how warm he was against him, and it set his heart racing. This was wrong.

She grabbed his arm and rubbed as hard as she could, the scarred flesh gave way to reveal soft pink skin. She pulled Dipper to the waterfall and sat him on a rock. She rubbed off the scar tissues from his back, legs, arms and chest. He could feel her kiss the new skin, and each time her lips touched him, it sent electricity through his body.

"I can't believe this is happening!" Mabel said. She seemed to be breathing rather heavy. The sounds of the falls crashed around them. Mabel sat on the rock next to Dipper and smiled. "Almost done…"

She caressed his face with both hands, using her thumbs, she rubbed off the tissue around his ears and his eye. She was careful not to press to hard or rub too fast. She pulled him to her and kissed his reformed eye. He held her, wrapping his arms around her frail naked form. Dipper held her as close as he could, feeling their hearts beating in time to their own music.

"Mabel…" Dipper whispered. She shushed him and didn't let him go. For once his brain didn't scream a thousand protests. He was in the moment, he was here, and that's all he wanted to be. Mabel pulled away to look at him once more, caressing his cheek. She leaned in to kiss his eye again, but Dipper moved her chin to meet his lips.

"What the hell?!" Dipper screamed in horror, slamming the laptop shut.

"KEEP READING!" Mabel squealed and punched his shoulder. "Why did you stop!"

"It's… gross!" Dipper cringed and took a breath.

"Hurry before she gets back!" Mabel said and bounced up and down. She was hugging a pillow in front of her with a death grip.

Billeah had just gone with Pacifica shopping and left her laptop unlocked. She is always typing on it, and the twin's curiosity got the better of them and snuck into her room to find out what's on it. To their horror, they found a folder called "Stories"

The latest one was titled "Terror on Tiki Island"

"Okay… oh god…" Dipper sighed.

As the two embraced, they realized their two hearts are one. Dipper carried Mabel under the waterfall and they entwined themselves under it's rejuvenating water.

A cold wind bit through their bodies, snapping them out of the carnal desires they fell into. Never letting go of each other, they retired to Mabel's Tiki hut to continued their new found explorations.

"Do you think this is the right decision?" Mabel asked Dipper. It has been a week since they found the Tiki people. Dipper nodded and tossed the torch into the boat. He pulled her next to him and watched as they severed their last thread to the outside world. No one will know what happened to them, they would be considered lost at sea, and that's what they wanted. They only ever needed each other.

"That's so romantic!" Mabel grinned.

"It's… she's writing about us Mabel!" Dipper said. "I really don't want to read anymore."

"Shush… keep reading!" Mabel giggled.

King Dipper and goddess Mabel decided to forgo their old life and rule the Tiki People. No one from the old world found them, and they were happy for years.

One day, king Dipper was surveying his land when he noticed smoke coming from the mountain. He saw a procession of Tiki People leading Mabel up to the volcanic mouth. His heart gripped in panic and he ran to his other half.

"What's going on?" king Dipper asked one of the Tiki. He responded to his king. They must pray to the the spirit of the mountain, he was angry. There was a sense of dread watching Mabel lead a procession up the side of the mountain. He followed along to make sure everything was safe.

"Be careful!" Dipper shouted ahead. Mabel grinned and stuck her tongue out at him.

"I'll be fine, just need to say a few prayers and… hey!" She said. two of the Tiki's bound her hands together. "What's going on?"

One of the Tiki's explained to Dipper. The goddess needed to meet with the mountain god to stop the destruction. Dipper explained it would kill her. The Tiki said if she was not a goddess, she will have to forfeit her life for her betrayal.

Dipper's mind raced for solutions. There were too many Tiki to fight. Mabel was already teetering over a rope bridge pleading to Dipper. The boat was gone, and they had no way off the island. There was no where to hide from the Tiki if they escaped and ran.

A wave of calm washed over Dipper as he knew what he had to do.

Dipper marched through the procession and stood by his sister.

"Dipper… what are you doing?" She said.

"Mabel, There's nothing we can do, if we run, they'll kill us. There's no where to hide and I can't lose you. I love you." Dipper said.

"I love you too" Mabel replied.

"Together?" Dipper asked.

"Forever."

Dipper held Mabel and kissed her for the last time. To the horror of the Tiki, their king fell with the goddess into the mouth of the bubbling lava.

As they fell, never letting go of their embrace, the Tiki watched. No one uttered a word as their goddess and king fell into the molten embrace of the mountain spirit.

The story of the king and the goddess passed into legend. For generations, the Tiki elders told the story of their pure love around the fires to wide eyed Tiki children.

The king and the goddess communed with the mountain spirit and saved them from destruction. They now live together as spirits of the twin waterfalls, healing those who ask and always watching over them for eternity.

Dipper finished the last line and rubbed his eyes. He was not crying, he told himself, just had some dust in his eye.

"I always knew you'd throw yourself in a volcano for me!" Mabel said. "Come here and give me a hug!"

"No!" Dipper recoiled.

"My Tiki king!" Mabel giggled and chased him around the room. Dipper ran away from his sister who made smooching sounds. Mabel chased him all around Billeah's room, giggling like a mad woman.

"Ah..hem" said a tiny voice behind them. Dipper and Mabel froze and saw Billeah in the doorway.

Billeah must have come back from the salon, the uneven bangs drew a line above her eyebrows, and the wavy hair was straight and long. The style mirrored the same Pacifica wore.

She sported a red and black lace dress he had not seen her wear before. Pacifica must have had a field day with her.

Without acknowledging Dipper and Mabel, Billeah walked between the twins. She closed her laptop lid without making a sound, unplugged it and left her room. She closed the door with a gentle touch, allowing the stunned siblings to hear the audible click as the door secured.

"You think she's mad?" Mabel asked. Dipper shrugged. He walked to the door to open it and found it stuck.

"Did she just lock us in?" Dipper asked. Mabel ran to the door and tried to open it but to no avail. Dipper pounded on the door.

"Let us out!" he bellowed, but no one came. "Yea… she's mad."

Dipper turned around and Mabel was giving him a devious grin.

"Looks like it's just us now… Tiki king!" She said and lunged at him.

"GO AWAY!" he bellowed and ran away from his sister.

"FALL INTO A VOLCANO WITH ME!" Mabel shouted and erupted in giggles as she chased her protesting brother around the room.

A/N: So.. we all knew Billeah's a twisted Fic writer. Comment your requests and see what her devious little mind will come up with… NOTHING IS SACRED inside her laptop!
