The first thing that Dipper did was putting his backpack next to his desk. After spending another day at school, it was finally the weekend. He looked at his calendar on his bulletin board. He was marking the days until his arrival of fun-filled adventures at Gravity Falls. That joyous, adventurous, captivating, yet treacherous summer left him with a strange combination of nostalgia and voidance. It was the summer when he had learn about the paranormality of the hidden town. He had constant wits and battles with the locals. He even had time for a brief summer romance, at least from afar. Most of all, his relationship with his sister became stronger.

Mabel has and always will be a foundation to him. She is the rock that keeps him anchored. She is the wind beneath his wings. She is the cheese and chili to his macaroni. She is the snow day to his Algebra class. Be as it may on the multitudes of cliches and smilies, Mabel is an important factor in Dipper's life. He couldn't imagine how life would be life without his older Mystery twin.

He scratched his cheek. His fourteenth birthday was approaching in a few months and puberty was already knocking on his door. At first, it was the subtle things: facial hair, heights, and his voice. He had already had a deep voice. He was nicknamed an old man at heart. He wasn't insulted by it. He considered it to be a compliment.

He opened his laptop and began to work on his homework. He wanted to get a head start on his assignment so that he doesn't have to be the one to worry at the last minute. Unlike his sister who would scream at the top of her lungs on his bed, begging and pleading for his help. And of course, he would be sitting there through the night finishing her assignment. Nevertheless, they were together. Side by side with cups of coffee and their favorite trance music.

Once again, he couldn't imagine a world without his sister.

He was an hour into his assignment when he heard the door opened from downstairs. Normally, he would keep his door closed when he studied, but today was an exception. His parents were out of town for the weekend. However, on different trips. His mother went to San Diego to go see their grandmother at the nursing home. His father went on a business trip in Salt Lake City. his father worked as an assistant to the pastor at their church. His parents were very conservative and very religious. The Bible was rooted in the twins' veins since they were young. Dipper and Mabel believed in God. However, Dipper looked at God as the old man staring at the world. Mabel looked at God in the same way, but believed that he intervene when it was necessary.

However, one thing that stuck out to them whenever they began their third year of junior high was when their parents were discussing about dating. His father believed in courting, believing that the pursuer must ask the parents for their blessing to date them. Knowing that the twin were labeled as millennials, the parents wouldn't allow either of them to date unless they went to them first. The only downside was that they couldn't date nor court until the duo was fifteen.

A year and some change to go, Dipper sighed with the horrid conclusion of his young adolescence.

The footsteps were growing closer and closer up the stairs until he heard a knock on his door.

Dipper tilted his head when seeing that it was his sister, Mabel. At the beginning of eighth grade, Mabel mustered the courage to come out of her shell and tried out for cheerleader. Initially, she did not make the cut. The coach admired her charisma and her optimism, but felt that she did not have sex appeal to join the team. Nevertheless, the young, lovable Mabel continued to support the team through fundraisers, competitions, and the like. The coach enjoyed her so much that she had decided to allow Mabel on the roster. At first, she did not receive support from the other members. Many made fun of her. There were many days she came home crying. She often sought the advice of her brother as she contemplated leaving the team.

Dipper remembered the advice clear as day when he told her. The duo were sitting outside of a coffeehouse one weekend. After taking a sip of his Americano coffee, Dipper took a few breaths, but explaining his opinion to his sister. "Satan gives us troubles so that God can give us victories."

He rested his hand on his sisters, giving her assurance of his support.

"If you quit this team, then they win. Mabel, you have the excitement that Piedmont Junior High needs. Damned the fact that you don't have sex appeal, which I must say is dead wrong. In my opinion, you are one of the most adorably dorky, yet sexy girl in the world. At least, that is in my opinion. I know that you are my sister. If you were not my sister, I would date you. We have a connection that many won't understand. So much so, that I want to find a girl under your image, because it is only one that can understand my humor. Let's face it, we are a foreign language of ourselves. But back to my point. A cheerleader is doing what they were called to do: cheer the team on, motivate them to win, and to comfort them when they lose. That is your job. Pardon my language, but fuck the other cheerleaders. Once again, if you were not my sister, I'd date you. Don't quit the team. Continue to fight. Storms are storms. Just weather and having gallstones, those painful moments will past."

Dipper was amazed with himself on how much he exhausted his thoughts to his sister. It was a mouthful, but he was openly honest. As he took another sip of his coffee, he watched how his sister was red in the face. She was flustered and surprised to hear what her brother had thought of her.

'You really mean it? If I weren't your sister, then you would date me?'

'Yeah. Why not? You are cool.'

"Hey, Dip-Dip," said Mabel.

"Hey, sis," replied Dipper.

Mabel was wearing her cheerleader outfit. It was the color of blue, yellow, and white. Honestly, he was happy and surprised that Mabel took his advice. She has remained on the team. In fact, she was the school's favorite cheerleader. She may not have sex appeal, but she brought the excitement back to it. Many of the football and basketball players started cheering her on for good luck. Lucky Mabe was the name and they looked forward to her in every single game. Because of that, the football won their district championship. Also, the basketball team were on their way to state. Now, the baseball team are convincing the coach to allow the cheerleader squad to perform at their games.

"How was practice, Lucky Mabe," asked Dipper teasingly.

She sighed as she walked into his room and lied on his bed. "Oh, my God. It was exhausting, Dip. All we did was just drills. We just exercised and exercised. We did not have any time to cheer at all." She stuck her tongue out in disapproval.

"Relax, Mabes," said Dipper. He continued typing on his keyboard. He wanted to get enough words for his paper so that if he had to pause, at least he had some progress done. "Cheerleader is not all about cheering. You must go through the fundamentals. There are basics. And that means keeping your body in shape."

She lifted her shirt off, exposing her stomach. From the small mirror in front of Dipper, he could slightly see Mabel's training bra. It was white. That sort of made him blush.

"I have a toned body," sighed Mabel. "It has been like that since training in November."

"True," said Dipper as he continued typing. "But it is important that you stay in shape."

"Blah, blah, blah," said Mabel before lying back down on his bed. She adjusted herself to lie on his pillows.

"Surprised to see you home earlier than usual," said Dipper. "Didn't have any dates?"

"No," said Mabel bluntly. "Wanted an early day. And since our parents are out of town, I wanted an early day to spend as much time I can with you."

"But we always spent time together, Mabes," said Dipper.

"No, not like that. Alone," said Mabel.

Dipper felt his stomach churned when hearing the final word in her sentence. Not further exploring it, he continued writing his paper.

Mabel grabbed one of Dipper's pillow and began smelling it. She took a couple of whiffs before placing it back beside her. "Whatcha working on?"

"I have a research assignment in Math," said Dipper. "You know the one that our teacher told us to do. You know, the one that she gave us three weeks to work on. You know, the one that if we don't finish and turn it in to her on Monday, then we can kiss our summer goodbye."

"Isn't our summer going to be at Gravity Falls again," asked Mabel.

"It won't be if you don't turn this assignment," replied Dipper. "Plus, your grade is treading near a D anyway. This assignment can give you a bump. At least a C."

She laughed. "'C' that you can help me on this assignment again, Dip-Dip," she said with a pout.

"'C' that you can grab your laptop and we can work on it together," replied Dipper. "We have the weekend. No excuse, sis. Time to woman up, Mabes."

Mabel stepped out of bed and into the direction of her brother. As he was typing, she tightly wrapped her arms around his shoulder and his sister. Upon impact, Dipper's breathing changed. He wasn't typing as fast as he should. The contact of his sister plus her perspiration was making him feel dizzy.

That day at the coffeehouse was an important day to Dipper. Although he tried to downplay it as brotherly advice, truth of the matter was that he was confessing his feelings for his sister.

He can't quite questioned when he started developing feelings for his sister, but he knew it was there. He compared it to an analysis of when people were aware of their sexuality at an early age. He had often thought of Mabel as a woman. There were moments when he started developed feelings beyond the sibling kind.

He kept them inside. He considered them as inappropriate. Coming from a religious family, incest was strongly discouraged. It was a sin under the eyes of God. He had once heard the pastor preached that incest was no different than homosexuality. He prayed many times a day for his inappropriate feelings of his sister to go away. However, the more he resisted, the stronger the urges became.

His feelings for his sister were confirmed when he went to a basketball game. His sister invited him and gave him the best seat in the house. It was in the center and court side. It was mid game when the Piedmont Junior High cheerleaders came to perform. He watched the girl came and did their routine. Of course, he saw his sister. Mabel's eyes were lit like Christmas trees when seeing her brother cheering and rooting for the team.

It was not the team he was rooting for. It was for Mabel. It was always Mabel. He watched his sister performed moves and stunts. Through shaking her pom poms and moving her body, Dipper studied and observed his nimble sister. Then, suddenly everything faded away from sight. The audience, the cheering, and even the cheerleaders. Dipper knew he was having an American Beauty moment as the lights were focused on his sister.

Mabel danced and moved seductively. Her eyes lingered on her body, inviting her brother to come and taste what she had to offer. From watching her supple breasts move to exposing her panties, it was a show reserved for Dipper.

Dipper's private show ended when a player from the opposing team crashed into him. His night ended at the hospital for a dislocated shoulder and a split lip. Despite that, in his eyes, it was worth it.

He was a Christian and a believer of God and his word. However, he couldn't fight the feelings he had for his sister. Despite the many prayers and the constant readings of the Bible, he could no longer handle the urge. Many nights were spent behind closed doors looking at pornography. Citing Japanese pornography as a primary source, it was a home dedicated to the taboo of incest. One of which gave him horniess, fear, redemption, and perspective was the well-known hentai Aki Sora.

Aki Sora gave him perspective on how a brother-sister relationship could lead. He was grateful that he was not as meek as Sora and Mabel didn't fit any descriptions of Aki or Nami, especially the latter of the sisters. He did fear about the consequences. There were many things to consider on if he pursued that route. That alone made him revert back into his closet.

"C'mon, bro-bro," cried Mabel, never leaving the sight of his brother. "Could you do this one more time for me."

Dipper noticed that she was clinging tighter to him. His heart began panting and his breath was becoming shallower.

"No, Mabes," said Dipper, trying his hardest to keep his composure. "If you have time to cheer, then you have time to do your assignment."

"But it is not the same when you help me," said Mabel. "I like it when you do it."

"So that you can get a decent grade," asked Dipper.

"No," said Mabel.

"Because writing is not your thing," asked Dipper. "Then yet again, you have stashes and stashes of journals of your love for Waddles."

"Nothing else can compare to the love I have for my widdle Waddles," said Mabel. "It is sad that he is not here. He is enjoying his stay at the pet hotel because our parents don't trust us with him."

Dipper shrugged before resuming his paper.

"There is one thing that can't be compared to Waddles," said Mabel.

"And that is?"

She blew into his ear. "You."

His finger shifted from the keyboard when feeling her breath in his ear. She began laughing before releasing herself from him.

"You are always fun to mess with, Dip-Dip," said Mabel laughing.

"Yeah, yeah," said Dipper. "I am just one cool customer of torment, am I?"

She leaned over next to him by his desk. "Yep! But I love nonetheless." She looked at the clock. "I am going to change out of these clothes." She was leaving the room. "I am going to take a shower. Let me know if I get any phone calls."

"'Kay," responded Dipper.

He could no longer concentrate on his paper anymore. He had closed the laptop and got out of his seat. He went down the hallway as he was hearing his sister turning on the water for the shower. After a few moments, she was inside of the bathroom.

It was in those moments that he had enough suppressing his desire. While she was taking a shower, he had sneak into her bedroom. He went through her closet where he saw the fresh pair of panties that she wore earlier that day. He retreated them into his pocket before hastingly returning to his bedroom.

He prayed to the Lord for forgiveness as he knew that this was going to be material when he closed those doors tonight. An engagement with him, her panties, his laptop, and with Aki Sora playing in his DVD.
