Inklings would often participate in a variety of contests, usually revolving around the theme of splattering ink everywhere. Today's contest would be something of a first, as it was the first time that Callie and Marie, the famous squid sisters, would face off with each other directly.

    The rules of the contest itself were a bit unusual too. Each of the sisters would wear their very own diaper, and a pair of inklings, each colored white and black respectively, would have to fill their diapers with as much ink as possible within the time limit. So perhaps it wasn't a direct face-off after all, but it was closer than anything that had happened previously.

    "Ready to loose?" Callie said, the black-haired (tentacled?) inkling thickly padding and winking teasingly at her sister. 

    "Only if you are" Marie retorted, her white diapers the same color as her hair.

    The inklings were split into two teams of three, Marie's team standing behind her, various splattery shooters at the ready, as Callie's team was doing much the same. The battle took place in a large area, consisting of a field in the center with walls and staircases on either end of it. Callie and Marie stood in the center on platforms, and the Inklings would have to rush to the far sides of the field to refill their ink, in case they ran out while expanding their team leader's diapers. The losers would face some unspecified consequence, that apparently only the two sisters knew about.

    A scoreboard hovered above the arena, a clock counting down to when the match would begin. Finally, the counter reached zero, signaling the start of another counter, this one measuring how long the match would take. 

    And the inklings were off, shooting paths of ink in front of themselves and gliding through it in their squid forms, while the Squid Sisters were left to leer at each other in the center, and occasionally shouting pep-talk at their team members from across the arena.

    Each team reached their refill zone at around the same time, filling up their weapons with ink before darting back on the paths they had already made. 

    The white team reached their leader first, an inkling leaping from her ink trail, landing right behind Marie. She took her weapon, jamming the barrel into the waistband of Marie's diaper, and holding down the trigger, a stream of ink quickly rushing into her diapers. 

    Marie's diapers began to swell rapidly, diaper filling up like a balloon, a big sloshy lump of ink sagging down in the back. 

    Before Marie had time to taunt her sister, the black team had arrived, an inkling doing the same as Marie's teammate had, jamming her gun into Marie's diaper, as a lumpy bulge of the thick ink settled in Callie's diaper as well.

    Callie's next two inklings were lined up, ready to fill up their leaders diaper, to a proportion hopefully surpassing Marie's, but the next Inkling in line found herself knocked back by a strong jet of ink to the face. 

    One of Callie's inklings striked back, hurling a pyramid-shaped grenade at Marie's team, which exploded in a burst of black ink that managed to temporarily knock away the opposing inklings, and disturb the path of white ink they had created for themselves.

    "The point of the game isn't to fight each other!" Callie said. Her inklings nodded, swimming across the length of black ink to replenish the ink they had just used up. 

    However, they found an obstacle on their path, namely a trio of inky grenades hurled by Callie's team, completely destroying the path they had created, with no way to replenish it, since their ink supplies were dry. Left with no choice, Callie's team had to trudge their way through the white ink, which to them was like tar, reducing all motion to a crawl.

    Meanwhile, Marie's team had recreated their path of ink, and were swimming along with ease, managing to refill their ink and reaching Marie with full tanks of ink and without a single hitch. The three inklings all crammed their guns into Marie's diaper at once, pulling the triggers simultaneously.

    Marie's diaper expanded at a stunning rate, gushing ink expanding it until she sat upon a massive mound of padding and ink, like an extremely tall bean bag chair.

    Callie gritted her teeth. "Come on, what's the holdup?" she said, glaring at her team. 

    Finally, Callie's team arrived, and having already used their ink to get rid of the white ink that Marie's team had left in their way, Callie's diaper was expanded to a size that was still large, but not so massive that she could sit atop it like Marie's. Instead, it sagged heavily between her legs.

    Meanwhile, Marie's team had arrived again, and Marie's diaper got another round of ink-filling, until Callie's diaper paled in comparison, as the diaper Marie sat on was about as tall as she was. 

    "Don't worry" one of Callie's inklings said. "I need you two to stand back"

    She crouched down and plugged her ears as her teammates stood clear. A rocket appeared on her back, summoned through the power of Inkling technology, sputtering from the back, eager to be launched. She fiddled with a remote, making sure that it would land in just the right position...

    The rocket did as rockets tend to do, that is, rocket into the sky, before come back down towards the ground, right above Callie.

    The Inkling must have been quite good at the art of rocket aiming, because the rocket managed to land perfectly, slipping right into Callie's diaper through her waistband.

    "What?" she said, not exactly sure what this large, monolithic object that she felt behind her was. 

    The rocket burst, releasing what could only be called a flood of ink, a massive explosion of the stuff, filling Callie's diaper immediately. 

    If Marie's diaper resembled a bean bag chair, then Callie's was more like a small hill, a massive mushy throne underneath her, padding stretched to five times Callie's own height.

    And this happened to occur just as the clock ticked down its final seconds, making Callie the winner.

    "And now I get my prize" Callie said, beaming proudly. "The privilege of eating the loosing team!"

    The loosing team looked shocked, not sure whether or not to believe Callie. Before any of them could try to flee, members of Callie's team had snatched up the other Inklings, restraining them, while Marie was left unable to move by her own massive diapers.

    Callie's team brought the losers to her, climbing up her mountainous diaper to plop the white inklings directly into her mouth. She swallowed the first easily, Inklings being slick and easy to swallow, as it appeared briefly as a bulge in her throat, and then one in her stomach. The next was presented to her, and she ate it with similar ease, moaning as it slid pleasantly into her ever-bloating stomach, which now squirmed furiously as the Inklings struggled within her gut. The final Inkling stood a similar chance as the rest, rounding out Callie's gut to an enormous, comical sized shifting mass of flesh.

    Callie seemed as though she would say something, before letting out an absolutely enormous burp, eyes shifting to her sister. "Looks like it's your turn, sis" she said, as Marie sighed, accepting her fate.

    The trio of Inklings grabbed Callie, working together to lift the enormous weight of her diapers up to Callie's mouth.    

    Callie swallowed her head-first. Marie, being an Inkling and similarly slick and slimy herself would make an easy meal. At least, her body would, the diaper would be another story. Callie swiftly made her way to to Marie's waist, her mouth opening wider to accommodate the massive, stuffed padding that came with her. Luckily, her biology allowed for her mouth to stretch open enough for the diaper to enter, and with the help of her Inkling team pushing her in, the diaper slid into her mouth. 

    Marie fell into Callie's stomach, now reaching its maximum size, sagging down to the ground, unable to support its own weight anymore with its four victims and massive, heavy diaper. The Inklings only continued to squirm, the prospect of being underneath Marie's diaper being almost as unpleasant as being inside Callie.

    "Well, I think it's time to finish this meal off" Callie said, feeling her digestive fluids do their job, her stomach shrinking quickly as her belly made short work of her prey. Before long, her stomach was much flatter, still gaining an extra layer of fat from her meal.

    "Only one last thing to do" Callie said, a strained look on her face as she squeezed, pushing out the digested remains of her victims into her diapers as an avalanche of white ink, causing her already massive diaper to increase in size even more.

    "Ah, that's fresh" she said.
