Celestia was all hot and bothered about balloons again. That's why Silver Spear, a decorated veteran of the Royal Canterlot Expeditionary Corps, was too big to fit through the doors of the barracks. His comrades pushed against his gigantic buttocks, while two more held his stumpy hooves and pulled, but it was no use. The stallion was wedged quite firmly into the doorway, and though wind spewed forth from both ends, it did little to lessen the immense pressure within his overstretched body.

The entire process would've been somewhat easier if the air spell that had inflated him weren't still active, somewhere deep within the cavernous depths of his near-spherical belly. Every second, liters upon liters of fresh air were generated and though some of it was expelled, the rest settled onto his flanks, his stomach, even his face; The stallion's coarse, scar-crossed face looked absolutely comical with a pair of soccer ball-sized cheeks and lips like the bloated puckers of some Griffonstani whore.

He thought back to previous campaigns, trying to think of a situation nearly as perilous and humiliating, but came up with nothing. Sure, Celestia sometimes utilized her fetish against the enemy, and yes, her soldiers were known to take advantage of immobilized targets – He still had fond memories of emptying his nutsack into the five-foot-wide ass of a breezie berserker, who mere moments before had been charging at him with an ax fifty times bigger than its minuscule body. He was just lucky to be here, among his comrades, rather than somewhere public where anybody could have their way with him.

“Keep pushing, boys, I think I saw him budge!” Thus spoke Princess Celestia, who was laying back on a beanbag throne while she played with herself. The stoic, eternal monarch of Equestria was as lewd and brazen as ever, her hoof running back and forth across the bloated nub of her clit. Silver Spear tried not to look, but it was clear that his comrades were distracted by the show, which probably didn't help his chances of ever escaping this confounded doorway! At least the guys in the back were still pushing, though his bloated ears could discern some unusual sounds coming from the other side. He didn't realize those thick, stiff things pressing against his underbelly and buttocks weren't hooves, but horsecocks; He didn't notice the ever-increasing amount of hot, sticky cum splattered across his backside. And most certainly, he didn't notice as he slowly began to enjoy his new state, his cock growing as hard as such an overinflated rod could be, looking more like an elongated balloon. Foamy cum leaked out, imbued with the same air as the rest of his body, and those boys in back guzzled it up as quickly as they could, not noticing how round their own bellies were getting from the second-hand magic.

At long last, however, something in his hide snapped. Some little connection broke, and before he could even scream, his body ruptured in a hundred places at once. The stallions in front of him were nearly flattened, while those behind were thrown clear across the room, slamming into a pile of conveniently stacked-up mattresses. All that remained of the stallion was a the acrid odor of magic and a few rubbery scraps, which soon disintegrated, leaving only the disoriented guards to tell of what happened. And Celestia, who scooped up two of the unconscious guards and teleported to her chambers for some more fun.

Some retirement party this turned out to be.
