Trembling and quaking about, Fionna struggles to make her way through the Candy Kingdom with Cake much farther ahead. Her pants and wheezes come out rapidly, entire body quivering and trembling as she repeatedly has to brace a palm against the wall to make her way forward. An audible *SLOSH* sounds out from her belly as she looks down below..biting her bottom lip at the sight of her lower body.

With a perfect, pear-shaped frame, Fionna was used to making others do a double take as she saunters by ,what with her sizable asscheeks and that thick, succulent belly and waist, plus a set of hips wide enough to be considered  "doorway" brushing. With all that chub , she's unfortunately left with a sizable appetite....which has now come to certainly bite her in the ass. After the recent feast with PG, she had taken more than her own fill of the expensive juice displayed for all the guests to consume.  Now, with gut jiggling and filled to bursting with the countless liters she gulped down..Fionna can only whimper as it became plain to see she couldn't hold back for long.

"A-aah...C-Cake wait up" she mutters forth, not even wanting to move as she holds a palm to her stomach, wincing a bit as her fingers sink into her softened tummy paunch with translucent beads of sweat drizzling down every inch of her filled-out physique. Her voice comes out especially faint, what with her body utterly strained to hold back what she *KNOWS* is to come. As such, Cake barely even hears her, still talking as if Fionna was right behind her as she makes her way towards the entrance of the kingdom. Fionna's cheeks blush white hot as she sees them leave her, rendering her feeling especially nervous as she looks about and sees the overwhelmingly large amount of others bustling about around her. Her bottomlip quivers noticeably so as she desperately looks about for any cover at all, bumping into others constantly as she stumbles about with hand still clutched at her gut while her vision slowly starts to go blurry with every passing minute.

At last, with no other options...Fionna darts to the nearest alleyway, hurriedly panting as she squats behind a trashcan...
And with her cheeks a crimson read and those marshmallowy soft legs spread..a steady trickle of of her amber colored urine begins to dribble off of her soaked shorts. Her mind goes utterly blank at this incredibly degrading act, eyes rolling back as the sudden relief of relieving herself so completely, all while her ass quakes and tenses up repeatedly at every ounce that cascades off of her moistened slit.

Fionna is left like this for a full five minutes, feeling like hours to her as she has to clasp one palm over her own maw (to hide her heavy breathing and moans ) and the other over the helm of her shirt, not wanting to get it sodden wet like the entirety of her undergarments at this point. A large puddle forms below her quivering, glistening ass, formed entirely of her steamy hot discharge, and still audibly trickling down her rear no less. When she's finally let out every single last drop...she stands, woozily, and stumbles onto the side of the wall. Standing there for a full minute to catch her breath and recollect her thoughts after such an OBSCENE act.......completely unaware that her antics have left quuiiite a few candyfolk enraptured by such a display.

Prince Gumball would certainly have quite the spit-take the following day, as there, directly in the first page of the newspaper , displays a black&white image of Fionna with her head craned back, mouth open slightly, and an immense waterfall of liquid down her fully-soaked loins.
