Mmm, seems like Minty was trying to escape the squeaky hooves of a huge puffy pooltoy pegasus, being the silly to-be balloon that he is~ Ducking into an inflatable building, he thought he was safe, and could relax and just enjoy the bouncy interior for a moment - buuut, that toy managed to spot him, and figured he could have some fun with the building’s bouncy exterior while keeping his balloon nicely pinned, and maybe starting to swell up, too~ With a few big sips from a tank of P-235, and a moment to locate a naturally comfily-lined valve on the back of the building, the pooltoy pegasus pushed it over with a big bouncy squeak, burying his muzzle into the doorway and straddling the puffy structure fully, putting in that first big huff of the fwhoompy orange gas. The dazed unicorn inside barely had time to get his bearings back before he felt himself starting to swell as he breathed in that first huff, and hardly had time to register that before finding the walls and floor all starting to push in against him, tossing him all around that bouncy room! That puffy pooltoy couldn’t help but let loose a small moan with their next huff, squeaks and creaks just filling the air as he bounced and humped into the building’s valve, knowing full well it wouldn’t be too long before he did get his puffy unicorn balloon~
 
A silly idea we both had, because lewd pooltoys and puffy situations are just fun~
