Seeing how scared her younger siblings were of her older sister's giant mouth, Maddie put on a brave face and stepped forward. While she couldn't save herself from Gabby's gut, she had an idea that could at least let her stall a little bit.
"Ooh, Maddie!" Gabby giggled. "You're gonna be so delicious." With that, she opened her salivating mouth wide and brought it closer and closer to her sister, eager to gobble her up.
"Wait," Maddie commanded with a surprising amount of confidence. "Before you eat me, just let me do something. I-I think you'll like it." This got Gabby to close her mouth just in front of the smaller sister. A chuckle came from behind the giantess' lips and she pulled her head back to get a better look at Maddie before giving her a two-word instruction:
"Go on."
What Maddie did next surprised everyone in the room. While doing a little dance, she slowly pulled her crop top off, revealing her bra and quite a bit of her chest. Katie and Cory's jaws dropped and their eyes widened while Gabby looked on avidly. Then Maddie gradually pulled her pants down, shimmying and shaking while doing so. Cory bit into his fist when he saw his sister's firm buttocks now only partially covered by her panties. Did Maddie know that he was seeing all this? Was she fine with that?
"Mmm, you look even yummier now, Maddie," Gabby moaned. "I wanna eat you so bad." The giantess stuck her tongue out and slowly ran it up the front of Maddie's body from her feet to her face, using her free hand to keep her miniature sister upright, before withdrawing her tongue. "Mmm, yummy yum." She then stuck her tongue out a second time, but this time, she just licked Maddie's chest over and over again before retracting her tongue. Although it had been Maddie's plan to make herself more appetising to her big sister, she couldn't help but blush at how the giantess was treating her. "You have really tasty tits, Maddie," Gabby remarked with a grin.
Then, at last, Gabby opened her mouth wide and the mouth engulfed Maddie. The giantess closed her eyes, made chewing motions, and rolled her younger sister around inside her mouth. Katie and Cory could only watch as Gabby's lips scrunched up and her jaw moved rhythmically and her cheeks bulged whenever Maddie was pushed into them. Through the whole thing, they could hear a lot of "Mmm"s from their big sister as she continued to enjoy Maddie's taste.
Eventually, Gabby tilted her head and her tongue back, causing Maddie to slide into her throat, where she was dragged down with a loud gulp. It didn't take long for her to reach Gabby's stomach, where she landed on a mushy pile of chewed-up pancakes. The chamber she was in rumbled and churned all around her as it tried to digest everything inside it. A loud, rhythmic thumping noise came from one of the walls.
On the outside, Gabby had lowered her two remaining siblings down to her gurgling belly and was using her free hand to pat it. Each pat made her belly groan audibly and her belly fat jiggle noticeably, causing Katie to cringe and Cory to watch on with considerable interest.
"Mmm, what a delicious sister I have," Gabby said with a satisfied sigh. "Yummy, yummy, yum." She then brought the two younger siblings back up to her face. "Let's see if I have two delicious sisters," she added with a cheeky grin as, with one finger, she tried to pull Katie's tank top off.
"Aah! Hey! Quit it!" Katie yelped as she batted the finger away. She was about to insist that she wasn't taking her clothes off like her elder sister did, but Cory put a hand on her shoulder, prompting her to look over at him.
"It's no use trying to fight Gabby," Cory admitted with a slow shake of the head. "Just go along with what she wants." Katie looked back at her giant sister, sighed in defeat, and slipped off her tank top and her skirt, leaving her in just her underwear - a sight that made Gabby salivate.
"I didn't think someone with such tiny assets could look so tasty," Gabby teased, leaving Katie a flustered mess. Then the giantess gave her youngest sister the same taste test as she gave Maddie: one long lick from her feet to her face, and then licking her chest again and again for good measure. "I don't know who's tastier, you or Maddie! Ooh, maybe once you're both in my belly, you can taste each other!" Gabby laughed heartily at her own idea, causing the two younger siblings to laugh nervously.
Then Gabby brought Katie into her mouth the same way she did with Maddie, and Cory witnessed his eldest sister's mouth go through all the same motions again. The lips scrunching, the rhythm of the jaw's movement, the cheeks bulging as Katie was pushed around inside the giantess' mouth. And of course, the intermittent "Mmm"s as Gabby enjoyed Katie's flavour. All of it eventually culminated in the big sister tilting her head back and swallowing the little sister with a loud gulp. Katie slid effortlessly down the throat and landed next to Maddie in the stomach.
"Maddie," Katie pleaded, "tell me you know a way out of here! I don't wanna be digested!" Before Maddie could answer, both girls heard a loud thumping sound over the background groans and gurgles.
Once more, Gabby lowered Cory down to her belly and patted it over and over again, causing a brief groaning and sloshing noise each time and making her belly fat jiggle again. While Cory was concerned about how Katie and Maddie were holding up on the inside, he couldn't help but blush as he stared at the giantess' plump belly.
"Mmm, two tasty sisters in my big belly," Gabby said happily. "I wonder when they'll get digested and turn into sentient fat on my body."
Inside Gabby's belly, the stomach acids were gradually working on the mushy pancake pile that Katie and Maddie were stood on. Once that was gone, the two ladies were next on the menu.
"Gabby said the shrink ray has an 'un-digest' setting, right?" Maddie voiced, her composure starting to leave her now that she was actually in Gabby's belly. "So the way we get out of here is by getting digested and then getting Gabby to use that setting on the shrink ray!"
"But I don't wanna get digested!" Katie cried, clinging on to Maddie like her life depended on it. At first, Maddie tried calming her down by hugging her, but then something that Gabby said earlier gave her an idea.
"Katie, lick my boobs."
"What!?"
"If they're as tasty as Gabby said, it'll take your mind off of her digesting us." Katie wasn't entirely convinced by Maddie's argument, but all the stomach noises and sloshing acids surrounding the two tiny women were scaring her, so she put her trust in her elder sister and gave her boobs a lick. Immediately her taste buds were hit with such a delicious flavour, and she wanted more.
Before Katie could get any more, however, Maddie gave her boobs a lick in return and found them so tasty, she wanted to lick them some more. And so the two ladies went into a breast-licking frenzy, tuning out the noises and acids in Gabby's stomach as it continued to digest its contents and she continued to pat her belly.
On the outside, all Cory and Gabby could hear coming from the big sister's big belly was the groaning and gurgling and sloshing and churning of a stomach trying to digest stuff. They had no idea what Katie and Maddie were doing inside the belly, but both of them figured it wouldn't be long before the two of them were digested. Cory suddenly realised that, while Gabby had eaten Katie pretty much straight after eating Maddie, she was keeping him out of her belly for quite a bit longer. Did she perhaps no longer plan to eat him, or was she just saving him for later, or was he about to be eaten now?
