>You're good friends with Pink Horse
>It's no secret that she has a massive sweet tooth
>She's pretty good in moderating herself, but there are some days where she slips
>This is one of those days
>"Mmf! Those really hit the spot, Nonny!"
>You're on the couch with Panko
>She's sprawled on your lap, her hooves patting her stuffed tummy
>You're sure she's set a new record as you pet her belly
>"Pffhee-hee! Keep that up, Nonny-HIC!"
>She's got hiccups now
>She starts laughing harder, her giggles punctuated by hiccups
>You can't help but smile as your hands explore the big pink swell of your stuffed giggly pony
>And another part of your mind wonders if she were a bit bigger
>You ask Pinkie if she's still got room
>"I -HIC!- dunno, Nonny. Lemme check!"
>She places one hoof on the side of her belly and slaps it with the other
>She giggles hard as her tummy wobbles
>You take it as a yes
>Standing up, you retrieve a cake and a pitcher of milk from somewhere nearby
>Pinkie's excited, her kicky rear hooves making her tummy bounce
>You hand feed her slices one by one
>Pinkie moans through each mouthful, her hooves rubbing her tummy all the while
>Once she's done with the cake, you bring the milk pitcher to her lips and start pouring
>Pinkie gulps loudly as she drinks
>Her tummy swells with each swallow
>After a minute and a half of chugging, the pitcher is empty
>Pinkie pants hard, her belly rising and falling with each breath
>She's a real sight
>Her belly went from a bloated paunch to looking like a big pink balloon
>The comparison is not lost on Pinkie
>She giggles up a storm, playing with her belly, feeling it slosh under her hooves
>"Hey, you -HIC!- can touch it too! Go on, Non-HIC!- Nonny!"
>Eagerly, you grasp her belly with both hands
>Pink balloon is right. It feels even softer and more wobbly than before
>Grinning like a fool, you squish and slosh her belly, making Pinkie moan and giggle
>Absentmindedly, one of your hands drifts lower while your other continues to massage Pinkie's belly
>Your wandering hand is inches away from her soaked cooch
>You hadn't noticed that she was getting off to this
>The sensual moans should have tipped you off though
>Apprehensively, you look back at Pinkie
>She's definitely noticed, her smile going from perky to seductive
>"How 'bout I -HIC!- sweeten the deal?"
>She produces a hitherto unnoticed platter of cupcakes
>You'd question it, but it's Pinkie Pie here. She can bend reality even when she's all bloated up
>It doesn't matter to you though. You like where she's going with this anyway
>You ease your fingers into her moist cooch, while your other hand makes its way to her bellybutton
>Pinkie shudders and moans, while practically inhaling the first cupcake
>Your breath goes heavy as you feel her growing under your hand with each cupcake
>Your hand is like a pneumatic drill, plumbing Pinkie's depths while Pinkie plumped herself
>As the last cupcake goes down, with nothing in her mouth, Pinkie shrieks as she cums over your hand
>You both cool off, with you absentmindedly rubbing the burbling pink dome in front of you
>"Mmm-HIC!-, that was soooo~ gooo-URP!-ood, Nonny..."
>Pinkie goes slack on your lap, quickly falling asleep in the afterglow
>Pinned by a heavy lump of pink pudge, you just sit there and massage Pinkie's tummy while she dreams of sweets
>Sleep soon comes to you as well, as you rest your head on her belly, lulled by her gurgling swell
>You hope to break the record next time, and see if you can get her from balloon to pillow
