Yet Another Zecora Thing [2nd person One-Shot Inflation]

>Zecora invites you over to help her test a branch of magic she had been practicing
>you walk in the door and greet her at the table
>you notice she's holding a miniature simulacrum of a pony in her hooves
>instead of cloth or wood, it's composed of a rubbery substance
>it's the same color as you, with a strand of your tail around its hoof
>with a sly grin she holds the mouth of the toy up to her lips
>in an exhale the doll already develops a small swell in its belly
>you look down as you hear a gurgle from your gut
>it already looks bloated as though you had a terrible case of gas, round and firm between your legs
>before you have enough time to think, you hear another huff
>and another
>and another
>before you even have a chance to escape, your legs can barely even touch the ground
>you're left teetering and bobbing on your swollen stomach, churning and creaking ominously
>despite the audible danger, Zecora is too fascinated in her discovery to stop now
>she even inserts a cylindrical cap on the space between the doll's legs to keep air from leaking out the other end
>you would have shouted as you suddenly felt a massive plug in your rump
>but she had the doll's lips clasped tightly in her hooves
>she continues filling her lungs, exhaling deeply as she expands the doll more
>its belly grows rounder in shape, filling out into a near-perfect sphere
>the once-thin balloon toy is now wider than its initial height, looking shinier than ever
>the doll even becomes transparent as its head and limbs sink into its hide
>much to your chagrin, and perhaps your pleasure, so do you
>puffy, air-filled cheeks reduce your speech to throaty moans
>your limbs flail helplessly, rubbing and bouncing against your overstretched sides
"Relax, my friend, take some pleasure!"
>she binds the doll's lips with an ornate ring
>sure enough, you feel the same tightness around your own mouth
>now you have no hope of passing air through any orifice
"For now, you are my little treasure."
