This can’t be happening, this can’t be happening! Mabel thought. She sat with her back up against a tree, somewhere out in the twilight of Gravity Falls’ forests, her head and legs pulled inside her colorful sweater as she did her best to hide away from the world. That day, everything in her life it seemed had turned for the worst. She had spent the whole day planning out her 13th birthday- the day she and her brother would finally become teenagers- only to find out that her two closest friends wouldn’t be able to come and that growing up apparently wasn’t the happy adventure she had been led to believe. Not only that, but that same day would also be the twins’ last day in Gravity Falls before they had to go back home, and leave all their new friends and recently-discovered family members behind.
But the part that upset her the most, was that now she would be going home alone.
Their great uncle Ford had offered to make Dipper his apprentice. And Dipper had said yes! How could he leave her like that? How could he make her go home and face high school all alone? It was bad enough that she would be leaving all her new friends behind, but her own brother? He was the one person she could count on! And why did he get to stay in Gravity Falls anyway? It wasn’t fair! She had helped on their adventures just as much as he had! But Dipper was going to get everything he wanted and she was just going to be left behind?!
If only there was a way I could make him stay with me… Mabel thought begrudgingly. Wait- maybe I can! she realized, her mind falling back to a particular adventure involving a certain mysterious crystal. The idea gave her a spark of hope and she latched onto it immediately. Yeah, this could work! I just need to get that flashlight…
She stood up, sticking her head and legs back out of her sweater and turning back toward the Shack. She moved quickly through the darkened woods, slowing down when she started to make out the lights through the trees. I need to get in without Dipper noticing, she thought. Luckily, Dipper was outside, rushing around the tree line and calling her name, obviously worried by the way she had run off.
It wasn’t long before Dipper went to check the woods behind the Shack and Mabel was clear to move. She ran as quietly as she could, through the door and up the stairs to their room. Once there she quickly went to searching through her brother’s things. “Come on, it’s gotta be here somewhere,” she muttered as she brushed past chewed-up pens, handwritten notes and the occasional picture of Wendy. Finally, she found what she was looking for, buried underneath a pile of notepads showing her brother’s unbroken board game winning streak. She pulled out her prize and then turned and ran back out the door, a serious expression on her face.
Just as Mabel reached the Shack’s front entrance, she came face to face with Dipper. “Mabel! There you are! Are you okay?” he asked. Then he noticed what she was holding. “Wait, what are you doing with that?” Mabel took her opportunity and quickly aimed the flashlight, flipping the switch before her brother could do anything to stop her. A few seconds later he was just a couple inches tall, groaning with a hand to his head as he recovered from the disorientation.
“Mabel, what- AHHHH!” came her brother’s tiny scream as she hurriedly reached down and grabbed him. She lifted him up into the air and then pulled her arm back inside her sweater depositing him in a little pocket she had sewn into the inside. “Welcome to Sweater Town,” she said quietly, looking around to make sure no one had seen.
The coast was clear, so she turned back around and quietly made her way back into their room. As far as anyone else knew she was still outside and Dipper was still out looking for her, so she quietly closed the attic door, knowing they wouldn’t be getting any visitors. She felt Dipper wriggling around in his yarn prison, so she carefully reached back inside her sweater and plucked him out of the pocket, holding him by the back of his shirt.
“What the heck Mabel?!” he yelled, though his voice wasn’t very loud due to his size, “What was that for!?” “You were going to let me go home all alone just so you could stay here and do nerd things with Grunkle Ford!” she whined. “So you shrunk me?! How does that help?” Dipper argued. “Well now I can make sure you stay with me all the way to California,” she replied in a superior tone. “What!? You can’t just keep me like this that whole time!” “Can too!”
“No way! I’ll just get that flashlight and regrow myself while you’re asleep!” Dipper asserted. “Not if I hide it!” Mabel countered, “Well then I’ll just tell Great Uncle Ford!” Dipper warned. That made Mabel a little nervous, but she tried not to show it. “Yeah? Well how are you gonna do that if I- um- put you in that cardboard box?” she asked, doing her best to quickly come up with a place to keep him. “I’ll just tunnel out,” he replied.
“Well what if I tie you to the ceiling?”
“I’ll untie the knot and use the string to climb down.”
“What if I lock you in the closet?”
“Please, I’ve already broken out of there at normal size. When I’m this small I can just run out under the door.”
“What if I throw you in a drawer!?”
“I’ll unscrew the knob from the inside and climb out of the hole!”
“What if I lock you in the chest!!?”
“I’ll squeeze through the crack in the side!”
“Oh yeah!? Well- well what if I eat you!!?”
To be honest, Mabel hadn’t really thought that last one through. She had brought Dipper right up to her face as they argued, and it was the first thing that had popped into her mind when she had run out of good ideas. But she had said it just the same and she wasn’t about to backpedal now.
“Come on Mabel. Just turn me back to normal and we can talk about this like normal people,” Dipper replied. He clearly hadn’t taken that last statement seriously and Mabel could tell her brother knew she had just blurted out the first thing she could think of; he thought he had won the argument. “No! I- I mean it! Either you agree to come home with me or you can spend the rest of your summer in my belly!” she managed, but her wavering voice gave away the fact that she was grasping at straws.
“Just give it up Mabel! You can’t make me go home with you!” Dipper maintained. “Awwwww” went Mabel as she opened her mouth wide, dangling her brother in front of her braces. She had been trying to convince him to come home at first, but now she just wanted to scare him. “Come on Mabel, I know when you’re bluffing,” he said, unimpressed. Seeing this, Mabel squealed in frustration and glared at her brother who stared back with a determined frown on his tiny face. Anger getting the better of her, she stomped her foot and shouted, “That’s it Dipper! You’re coming home with me one way or another!”
And without another thought or another word, Mabel opened her mouth wide and threw her brother in.
At first Mabel just stood there awkwardly. Having acted on impulse, she hadn’t really made a plan as to what to do next. But then Dipper started to move, wriggling around to try and get into a comfortable position while no doubt trying to push himself away from his new slimy surroundings. She felt his tiny hands and knees tickle against the top of her tongue, causing it to squirm out of reflex.
“Ugh! Mabel! Spit me out! This is gross!” Dipper yelled in a clearly annoyed voice. “No way, not until you say you’ll come home with me!” she insisted, having a hard time talking around the form in her mouth. To drive her point home, she started rolling her tongue around, licking at her brother and covering him in her saliva. As he tumbled around, wrestling with the slimy muscle, Mabel started to notice something: Dipper… he actually tasted pretty good! She pressed him lightly to the roof of her mouth, soaking in some of the flavor that poured off him.
She relented for a moment as she savored the strange sensation that coated her tongue. “Ptew! Bleh! Aw, Mabel! Come on! I have your spit in places there should never be spit!” Dipper complained. Mabel had heard him, but it hadn’t really registered. She was far too focused on the new world of experience that she was discovering as he pushed himself around on her supple tongue and her saliva continued to soak into his clothes, drawing out more and more of his flavor.
“Mmmm, Dipper you taste goooood…” she said, half moaning. “Mabel! I’m your brother, not a snack! Spit me out already, you’ve made your point!” he replied. His tone seemed to suggest that he was thoroughly irritated and a bit desperate, but not really worried. Under other circumstances he might have been seriously concerned about actually getting eaten; but this was his sister he was dealing with, she was just stubborn and upset and wanted to get some payback. If only he could see the look on her face after what happened next.
See, Mabel hadn’t quite lost track of what she was trying to accomplish, but it was safe to say she had let herself get more than a little distracted as she indulged. Her brother’s taste had been an unexpected bonus and she decided it only lent to her act to show that she was enjoying it. Unfortunately, to her body this was much more than an act. She hadn’t really noticed, but the moment that flavor had hit her tongue, she had started drooling. As Dipper moved around more and more, angrily punching at the squishy flesh to try and get the message home to his sister, his slippery surroundings were quickly becoming flooded with her saliva.
And that’s when it happened. A particularly jerky move of her tongue sent a puddle of spit against the back of her throat, almost causing her to gag, and out of reflex she gave a small swallow. But her eyes shot open wide as she felt something distinctly solid squish against the back of her tongue before disappearing down into her throat.
Mabel clasped her hands over her sealed lips, terrified for a moment that she had just accidentally swallowed her brother. But her senses quickly told her that he was still there, pressed securely up against the roof of her mouth. She slowly lowered her hands and let herself breathe again as she made out the muffled words of her sibling from atop her tongue. “Mabel did you really just swallow my hat!? How am I supposed to get that back!? Ugh, you know what, I don’t think I’m gonna want it back after where it’s been…”
Mabel might have given up the whole thing right there, except… As much as that had just scared her- and it had scared her- somehow the thought of swallowing Dipper had also been… amazingly… satisfying. She thought back to the experience again and she couldn’t deny that she lingered on the imagined sensation of her brother’s form sliding past her tickled tongue, slipping down into her throat as it guided him down to her waiting belly where he would lie, filling her tummy with his cute little wriggles.
She almost couldn’t believe it. She wanted him down there, tucked away inside her, completely… hers… That would make him hers wouldn’t it? He wouldn’t ever be able to leave her, nothing could ever separate them if he were in there. But just as much, she also just wanted to feel that feeling of him sliding down to her stomach, oh her body was almost pleading for it.
She shifted her tongue around a bit more, slowly, gently, as she struggled with the decision. Her saliva, filled to the brim with Dipper’s flavor was dangling at the edge of her throat, begging her to swallow everything down to its rightful resting place. After a long moment of consideration, she took a deep breath, and then spoke.
“Dipper, are you ready to come home?” she asked. “Okay, fine! Yes!” Dipper conceded, obviously tired of being squished around in his sister’s mouth. Mabel paused for a moment and smiled. “Glad to hear it, bro,” she said quietly. She left her mouth hanging open after the last word, but not quite enough yet that Dipper could crawl out. So instead he just stuck his head out, getting a breath of fresh air.
Mabel looked down at him, his hair drenched with her spit. He seemed relieved. “Phew… you know Mabel, for a second there, I almost thought you might really-”
*GULP*
Mabel snapped her eyes shut and slurped her brother as far back as she could, swallowing deeply- the way she had been wanting to all along. She felt him slide halfway into her throat, his midsection pinned within her neck by the back of her tongue. Mabel’s mouth drifted back open as she savored the amazing sensation and the renewed flavor. Dipper stared out at their room through the space between his sister’s teeth, “Mabel! NO!”
Slowly, Mabel raised her tongue, pushing her brother ever so gently further and further back until finally her tongue reached the roof of her mouth and she swallowed. She shuttered audibly as she finally felt Dipper begin to slide down her throat. She could feel every inch of him, slowly descending through her neck, disappearing from sight inside her chest and then finally slipping into her waiting belly with a satisfied gurgle.
Mabel sighed in satisfaction as she walked over to her bed and flopped down onto her back. She rubbed her hands across her belly as the incredible feeling of her brother’s wriggling began radiating from her stomach. “Welcome to Sweater Town, Dip; your new home.”
It was everything she had imagined it to be. The fullness of her belly gave her a warmth that spread throughout her body, her brother’s movements like a delicious massage across her insides. But it was more than just that, because this was Dipper inside her; her twin brother now the contents of her stomach. With him so close, it was impossible for her to feel scared or alone.
“Mabel! No! Why!? Let me out!” came a faint cry from beyond her skin. “Bro, it’s okay, it’s okay!” Mabel replied. “You were just so tasty, I couldn’t resist,” she explained. “Mabel I’m in your stomach!!” Dipper yelled. A loud gurgle rumbled from her insides as she felt him press extra-hard against the soft flesh inside. “It says hello,” she giggled. She felt a small shift in pressure as her stomach pushed back at its contents, and then a sudden burp flew past her lips.
“You do know what digestion means right!!?” Dipper pleaded. “Yeah, yeah, don’t worry Dipper. You did say you would come back home with me, and I guess that is better than keeping you in there… Did you find your hat yet?” There was a moment of silence as Mabel felt her brother searching around. She had to fight off the urge to moan at the sensation.
“Got it!” Dipper announced. “Good… now, just give me a couple minutes…” Mabel said, giving in to the pleasure flowing from her belly once again.
“MABEL!!”
*Gurgle*
*Giggle*
