(This story assumes that you have watched the tv show, the twins are 2 years older and their bodies are much more developed.)

It was a warm night in Gravity Falls Oregon the cicadas were humming the crickets were chirping it was a peaceful time, 14 year-old Dipper pines and his fraternal twin Mabel pines were walking in that forest. Dipper was looking in his journal, and Mabel was walking right next to him, she would never admit it but she was scared sure she had been in the forest plenty of times, but never this late at night. Something Slithered out of a bush and Mabel, screamed and grabbed her brother's hand, and pulled him through the woods at a breakneck pace she had been running for about 10 Minuets when she finally stopped. Mabel was shaking and could not control her breathing.

Mabel yelled. "This is so stupid Dipper why are we here." "Well there is this thing I found in the journal that only comes out at night." Explained Dipper. "That does not answer my question Dipper." Said Mabel with tears starting to form in her eyes.

That's when Dipper realized just how scared she really was. Oh man he thought I am such a prick.

"Hey Mabel come here it's okay I'll protect you." Said Dipper in the most caring voice he could muster. Mabel came over to him and hugged him. This made Dipper blush, because her nipples were pressing up against his body, but he chose to ignore this so he could comfort his sister. Her heavy breathing subsided after a minute. "Thank you Dipper I needed that hug." As she said this she looked up and noticed him looking away and blushing she could not figure out why he was blushing,but then she noticed her nipples digging into his chest and laughed in her head sometimes her brother was so awkward. "Let's go home Mabel, I should have asked if you wanted to come instead of dragging you out here." Said Dipper still blushing about the hug. "Thanks Dipper I'm so sorry about this." Said Mabel still smiling at her blushing brother. "Alright Mabel lets go... And will you please get your nipples off me now it's making me uncomfortable." Said Dipper yelling the last part. Mabel couldn't hold it back any longer she burst out, laughing and said. "Dang brother why you so awkward?" "Yeah yeah yeah let's just get going Mabel." Said Dipper Still blushing, but now with a smile on his face. And so they trekked back home.

(The next day)

Mabel was sitting on her bed rocking back and forth, she had not let Dipper know about the strange dream she had, and right now she had the room all to herself. The dream happened after they got home out of the woods.

(Dream sequence)

Mabel was back in the woods hugging her brother, and she noticed this was obviously a dream and a dream she couldn't control. It of course started with them hugging but then it started spiraling out of control Dipper reached down and Kissed her cheek and then She (dream her) kissed him full on the lips they held it for a long time then She started to take off her brothers shirt and he did the same for her then they started to feel each other up, as dream Dipper began to take off Mabel's bra, as the connector snapped the dream ended.

(End of dream sequence)

This is why Mabel was rocking on her bed, she had nobody to talk to about this. Just then Dipper walked in the room and saw her crying, he thought about it for a minute and then walked in. Mabel didn't notice him until he sat down on her bed. "Go away Dipper please go away I want to be alone." Then she noticed something Dipper was hugging her, a good old fashion make you feel better hug. He wasn't even blushing he was just there for his sister in need. It was Mabel's turn to blush, she had never felt so good just from a hug. Dipper released her from the hug and said. "Mabel whatever is troubling you I can help. "I'm sorry Dipper but this is a thing that can't be shared with a family member, especially not you, I mean no offense or anything Dipper but it's just too personal." "I understand Mabes but if you do ever want to talk about whatever's going on I will always understand." "Thanks Dip maybe one day we can talk about this, but not now." "That's okay Mabes remember what I said." As Dipper left Mabel thought to herself and decided one day they would need to discuss this but not now, not quite yet.
