Chapter 5: The Bond Between You
Dipper walked through the door into the front hallway of his house. Mom and Dad were standing there, seemingly waiting for him, and they both looked furious. On the stairs behind them sat Mabel, her face streaked with tears. Dipper knew immediately what had happened: His parents had found out.
“How could you do this?” his father shouted. “We have never been more disappointed in you!”
“Or ashamed of you,” his mother lamented.
“But, but I-” Dipper stammered, “it- it wasn’t me! It was the other Dipper!”
Aphrodite appeared and blew a ring of smoke into Dipper’s face, making him cough as she said, “Dipper is Dipper, kid.”
His father seized him by the shoulders. “We’re going to have to decide what to do with you. But you can’t be part of this family anymore. Not after what you’ve done, Dipper!”
“Dipper! Dipper!”
“Aaaaah!” Dipper screamed as his eyes flew open.
Mabel stood over him, shaking him by the shoulders. As soon as she saw that he was awake, she grabbed him and held him tight, burying his face in her hair.
Her lips by his ear, Mabel murmured, “That must have been a really bad dream.”
“It- it was,” Dipper gasped.
“It’s okay,” Mabel said, rocking him gently. “It’s okay now.”
For a split second, Dipper wanted to break away from Mabel and run, reflexively fearful of his nightmare-parents’ judgement. But the warmth of Mabel’s embrace, the sweet, familiar smell of her hair and the feel of it against his face…these things seemed to push back the dread with which he had awakened.
They always have, he thought. Even when we were little, she could always chase the nightmares away.
He wrapped his arms around Mabel and held her as tight as she was holding him.
“Thanks, sis,” he whispered.

“This,” Grunkle Stan said sternly as he slapped a copy of the Gossiper down on the breakfast table, “is not good for business.”
Dipper’s eyes went immediately to the title of an above-the-fold article: “Trouble in Paradise? Dejected Dipper Wanders Alone in Woods.” Below that was a photo of Dipper from the previous evening, shuffling into the woods behind the Shack.
“What the heck?” Dipper exclaimed. “Who even took this picture?”
“Toby Determined strikes again,” Stan grumbled. “Little pappa-ratso spends more time hiding behind our trash cans than the raccoons.”
“We should set traps,” Mabel suggested. “We could bait them with pictures of me and Dipper kissing!”
Ignoring Mabel, Stan said to Dipper, “Look, kid, unhappy couples may sell newspapers, but they don’t attract tourists—not the spending kind, anyway. So I need you to get out there this morning and show your adoring public how much you love this girl.” He squeezed Mabel’s shoulder.
“How am I supposed to do that?” Dipper demanded.
“I dunno—hug her, kiss her, play with her hair, make goo-goo eyes at her, whatever it takes!” Stan barked. “I don’t care if you have to do her right there on the front por-”
Stan stopped, then took a breath.
“Look, just…go out there and make nice, all right?”
“Okay, Grunkle Stan,” Dipper sighed.

The day was much less busy than the one before, chiefly because it was raining heavily at opening time. Stan handed Dipper a flimsy Mystery Shack umbrella and sent him down to the market for some light bulbs (“The generic ones! Brand-name bulbs are a scam.”), and the walk gave him time to think—something he seemed to need a lot of on this tour of universes.
By and large, Dipper managed not to dwell on his nightmare of that morning. But one piece of it seemed to be stuck in his head: Aphrodite saying, “Dipper is Dipper,” the words she had used when she explained to him that any given person is fundamentally the same in every universe. This brought Dipper to an uncomfortable realization, even as he strolled through the automatic glass doors of the local supermarket.
I’m attracted to my sister.
The logic was inescapable. If all Dippers were basically alike, and if the Dipper in this universe was hot for Mabel in the way that he obviously was, then Dipper Prime, as he had begun to think of himself, must have those feelings on some level, too.
It was an uncomfortable thought, even though the discomfort was mitigated somewhat by alter-Dipper’s easy acceptance of it. But as Dipper found and paid for the bulbs and walked back to the Shack, he could think about nothing else. Especially when he realized that by the same logic, Mabel Prime must be harboring the same sort of below-the-surface attraction to him that he had for her.
When Dipper got back to the Shack, there were no customers inside. Soos took the pack of bulbs from Dipper and went off to install them. (“Thanks, dude. I must now go and bring light where there is darkness.”) Wendy was napping in her chair behind the gift shop counter, her cap pulled down over her eyes. Dipper didn’t see Mabel or Stan, but over the sounds of Wendy’s soft snoring and Soos humming to himself as he changed light bulbs in the next room, he could hear their voices coming from Stan’s office. Dipper’s curiosity getting the better of him, the boy crept to the office door and listened.
“C’mon, it can’t be that bad,” Stan was saying. “Famous people deal with this kind of stuff all the time.”
“I’m just worried about Dipper,” Mabel replied. “I mean, he looks exhausted, he’s having nightmares…he’s just not himself lately. You’ve got to take it easier on him.”
She was defending him. Watching out for him. Impulsively, Dipper threw open the door and strode in.
“It’s not just me,” he said, looking Stan in the eye. “Mabel’s been totally stressed out. You’ve gotta back off on this whole celebrity thing.”
Stan looked at him in surprise, then with an accusatory glare, no doubt because it was clear that Dipper had been listening in.
Dipper expected Stan to argue, or try to sweet-talk him and Mabel, or maybe just to tell them to suck it up. Instead, the man sighed and lowered his eyes to the floor.
“I’m a lotta things,” he said slowly. He counted on his fingers as he went on, “A swindler, a fraud, an embezzler, a tax cheat, a forger, an arsonist…although that last one was just an insurance thing that got outta hand…”
He looked up at Dipper and Mabel. “My point is, one thing I’m not is a pimp. But I’ve been acting like one, and that’s not fair to you kids. So…I’m sorry.”
Mabel hugged him. “Thanks, Grunkle Stan “
“Thanks,” Dipper agreed.
After a moment, Stan said, “Tell you what. There’s nothing going on here anyway; how about you two go relax until dinner time? Then I’ll make you my famous one-bean salad.”
“That…that sounds great,” Dipper replied.
“Yeah,” Mabel chimed in. Then she took Dipper’s hand, and they went upstairs.
Once the bedroom door had closed behind them, Dipper said, “Mabel…thanks for standing up for me with Grunkle Stan.”
“Of course,” Mabel replied. “You’d do the same for me. Actually, you did.”
She moved closer. “You’re my brother,” she said softly, “and I love you.”
Dipper put his hands on her shoulders. “I love you, too.”
He kissed her. It was less than a full-on smooch, but more than a peck. Definitely a boy-girl kiss. And it wasn’t for Tiffany Litz, or any other girl Dipper might have thought of. It was for Mabel. His sister. His girlfriend. His lover.
She kissed him back, putting her arms around him. He held her close as the kiss grew more passionate. Then Mabel pulled Dipper’s hat off and threw it onto his dresser so she could run the fingers of both hands through his hair.
The smell of her hair, the soft warmth of her body against his, and the ardor of her kisses made him feel aglow inside. Love and lust swirled within him, and he found himself seizing the hems of Mabel’s pink shooting-star sweater and the tank top beneath, pulling them upward to expose her stomach. Mabel took the cue and raised her arms, and then she was stripping off Dipper’s T-shirt and they were kissing again, with nothing between their chests but Mabel’s white training bra. He reached behind her and fumbled with the clasp for several seconds before Mabel took pity on him and unhooked it herself.
Still making out with abandon, they fell sideways onto the bed. Dipper rolled on top of Mabel and began kissing his way down her neck. She again twined her fingers in his hair.
“Oh, Dipper…” she moaned softly.
It turned Dipper on to hear Mabel speak his name with such passion, just as it had the night before. But this time, his reaction didn’t bother him. It still felt strange, but it no longer felt wrong.
He kissed his way down to the base of her neck, over her collarbone, and down to one of her puffy brown nipples, which he kissed, then licked, then sucked. Mabel’s hold on his hair grew tighter.
“Mmm, Dipper…” she murmured. “You’re always so nice to me…”
He stopped sucking her nipple and moved his face up next to hers, putting his lips to her ear.
“Because you deserve it.”
Teasingly, she replied, “That’s it—no more pants for you.”
He let her reach down and undo his shorts, then slide them off his hips along with his briefs. He felt her grasp his now-exposed cock in her hand.
“Hello, Mr. McBonington,” she said with a braces-studded grin. “Looks like you’re having a ‘hard’ time.”
“Mabel,” Dipper warned, “bad puns are not the way to get Boney to stick around.” His acquired memories indicated that this was not the first time he had cautioned Mabel about using her particular brand of humor during intimate moments.
“I don’t need him to stick around,” she retorted, letting go of his penis to slide off her skirt and purple undies. Then, spreading her legs, she continued, “I need him to come inside.”
Dipper didn’t know whether this rather subtler double entendre was intentional on Mabel’s part, but, either way, it restored his erection in full.
He got fully on top of her, his hips between her slightly chubby, widely spread thighs. Her arms went around his shoulders.
“Get in here,” she said, teasing and warm. He smiled at her, then began to sink in.
“Mmmm…” they hummed softly in unison.
When he was all the way inside her, he opened his eyes and looked at her. It was still pretty weird, looking into the smiling face of his own sister, inches from his own, while his penis was in the snug embrace of her love channel. But now, it was a good weird—something to be explored and experienced, like so many of the other strange things he had encountered since his arrival in Gravity Falls.
He lowered his head next to hers, and her arms tightened their hold on him. Dipper’s mind flashed back to that morning, when Mabel had held him after his nightmare, and he realized that in a way, this was no different. She was embracing him out of love.
Slowly, he pulled out and pushed in again, wanting to savor it, wanting Mabel to savor it. She sighed happily in his ear.
He did it again, and again, and now Mabel was moving with him, pushing her hips up as he pushed down. He relished the feeling of being this close to her, and the thought that she wanted to be this close to him.
“Dipper,” she whispered. “I love doing this with you…”
“Ohhh, Mabel…” he breathed in reply. “I love you so much…”
Aroused further by Mabel’s words in his ear, Dipper began thrusting a little faster. Mabel kept up with him, and he felt her reach down and take hold of his hips, pulling in time to help him thrust into her while she thrust up against him.
Dipper didn’t know how long they did this; he was in a haze of pleasure that dulled his sense of time. And even though part of him wanted to hurry up and get to the big finish, for the sake of Mabel’s satisfaction he was able to ignore it and continue taking it slow.
Until, that is, she began to make an “Uh” sound in his ear with every thrust. To Dipper, the sound was compellingly erotic, and the next thing he knew, he was biting his sister’s neck in a fit of passion.
“Oh, God!” Mabel cried, clutching him.
And just like that, they were going at it hard, fucking, panting, grunting, holding on tight, loving each other with every ounce of effort they could force from their bodies. They thrust and gasped and whined and shouted mindless words of pleasure, and then they were screaming, screaming together, each of them driven to greater ecstasy by the sound of the other’s climax.
When it was over, Dipper rolled off of Mabel and lay next to her, feeling the odd aftershock of orgasm as he gasped for breath.
“That was…really nice…Dipper,” Mabel said, still breathing hard.
“Yeah,” Dipper panted. “It really was.”
After they had both caught their breath, Mabel said with a chuckle, “I think you gave me a hickey.”
“Oops. Sorry,” Dipper replied. “I kinda got carried away, there.”
“Don’t be sorry; it’s neat that I can make you that excited. And Grunkle Stan’ll be happy—you know, ‘cause it’ll show how well we ‘get along.’” She grinned.
He took her hand in his and squeezed it.
“I’ll always get along with you, Mabel,” he said sincerely. “In any universe.”
She blinked. “Huh?”
Before Dipper could reply, he felt himself being pulled out of his body and up into the air. The world spun for a moment, and then he was back in the clearing in the forest.
Aphrodite, leaning against a tree, took a long drag on her cigarette and blew a stream of smoke into the air. She seemed to be waiting for Dipper to speak.
“At first,” the boy said slowly, “I didn’t get why you sent me to a universe where I was dating someone who wouldn’t even be an option for me in my own universe. But…”
“Go on,” Aphrodite said.
“But Wendy was never an option for me, either. Not really—in any universe. So I think showing me the options isn’t what you’re doing, here.”
Aphrodite nodded. “I never said I was going to help you find the perfect girl. I said I would help you figure out who the perfect girl for you is.”
“Right,” Dipper replied. “So I think…I think you’re trying to teach me something.”
“And what did you learn from this trip?”
Dipper looked upward, thoughtful.
“People always ask,” he began, “why Mabel and I get along so well, when we’re hardly anything alike. And I think part of it is that, deep down…we’re attracted to each other.”
Aphrodite nodded again. “Yeah. You can’t ever act on it, not like the other Dipper and Mabel can, but it’s there. It’s part of the bond between you.”
“But there’s something more important than that,” Dipper went on. “It’s that…we watch out for each other. When it comes to things that matter, Mabel always has my back, and I always have hers.”
With a hint of a smile, Aphrodite said, “I got hope for you yet, kid.” Then, after one more puff of her cigarette, she asked, “So, you ready for the next universe?”
Dipper straightened up. “I feel ready for anything.”
Aphrodite’s smile turned crooked in a way that Dipper found unnerving.
“That’s good,” the chain-smoking goddess said cryptically. “‘cause here we go.”
“Wait, I actually have one questio- AAAAAH!”
He was tumbling through space again, disembodied. And then he landed in a new body.
He was outside, bracing himself against a tree as he regained his senses. After a few moments, he realized that he was at the edge of the woods behind the Shack. The sun was descending in the western sky, and Dipper’s newly acquired memory told him that he was on his way home after another round of putting up ads for the Shack.
He saw the blue glow of the TV through the window of the Shack’s dilapidated living room. Mabel sat by herself on the threadbare sofa, watching the television.
From behind the couch, something rose up silently. Dipper couldn’t be a hundred percent sure what it was, but it was humanoid, hairy, and big. Its large hands began to reach for the back of the oblivious Mabel’s neck.
“Oh, boy,” Dipper gasped, and he ran for the Shack’s back door.
