Chapter 1/ The whole thing
“Time to try out this spell!” shouts the excited purple alicorn. Twilight Sparkle takes a deep breath to calm herself. Recently, she discovered a new spell in her book that supposedly could turn ponies into living blimps. It did sound pretty weird, but oddly fascinating at the same time. A magical aura begins to surround Twilight’s horn as she begins to cast the spell. She doesn’t feel much happening for a moment, but she soon feels something building up in her belly along with a low hissing sound. She takes a look below and sees her purple slim belly bulge out. “Ooo. That’s interesting.” Twilight comments, becoming quite intrigued at the sight of her own belly expanding.
The spell continues to do its work. Her belly keeps expanding outwards and soon touches the ground below her. The magic begins to spread out to the other parts of her. Her rear suddenly billows out just a bit, while her chest puffs out just a little. Twilight feels her cheeks swell out, much like a chipmunk's. Her already bloated belly starts to lift her up from the ground. All the while, Twilight grins and becomes more fascinated from just simply feeling and watching her whole body inflate like a balloon.
Twilight keeps pushing her balloon body outwards even more. She feels her legs shake a little before they start to thicken and bloat as well. She wiggles her inflated limbs to get a good feel for them, and it doesn’t take long for Twilight to begin to float slowly up the sky. The quiet hissing that emitted from her body earlier becomes louder, along with sounds of a balloon stretching. She lets out some giggles while shaking her big rump cheeks. She smiles for a moment before she starts feeling pressure idly building around the center of her huge belly. She tries to figure out why this is happening until she hears a loud popping sound from below her belly. She doesn’t know what it is until she feels a cool breeze swing by and brush against her belly. It makes her shiver and let out a quiet moan, but she is able to figure out what that sound was. It was the sound of her belly button coming out as a cute, little dome for her belly.
Twilight smiles brightly at the sight of her large body still growing. Her bloating forelegs start to move to her sides and grow stiff. Her large, swollen belly wobbles, while emitting the sounds of a balloon stretching. She slowly rises higher and higher above the houses of Ponyville. She wags her tail happily above her lovely, round rump cheeks. Her body is starting to cast a small shadow on the ground. She looks up to see clouds floating closeby. She grins widely with her swollen cheeks, looking like two purple soccers balls smooshing her muzzle. She is full of excitement just by seeing and feeling herself become so big.
The magical aura surrounding her purple horn soon fades away. The loud hissing soon becomes silent. Her body’s inflation finally comes to a halt. Twilight’s grin grows wide, moving her large, plump cheeks a little apart. She slowly wiggles her thick, puffy forelegs and hears them make light squeaks. Her star cutie marks have been stretched quite a bit to cover the bloated surface of her flanks. She happily wags her massive butt cheeks to feel them wobble. Another cool breeze brushes past her swollen belly and puffy navel, causing Twilight to shiver and release a blissful moan. “Woooo! This spell is amazing!” the purple zeppelin shouts while wiggling her puffy hooves. The result exceeds way past any expectations she had for it. She is now a big blimp, floating cheerfully through the sky. She begins to think of an idea for the spell. If one cast of the spell made her this big...what if she casts it twice, three, or even four times? There is only one way to find out, and Twilight is more than happy to repeat it.
