Looking for a vast air inflation that puffs you or me up bigger than any building, or mountain. They feel their abdomen swell, and as the discomfort sets in, they notice it’s their belly. They try their hardest to hold it, and once they can’t possibly hold it any further, they would be forced to end it with one massive, continuous gigantic fart deflation that blows away anything in it’s path and lets them deflate them down to a wrinkly stretched out flattened form RP.
I.E.
I just thought of a situation where a female Pony gets inflated by a stallion from her rear. Gets caught up in a storm that washed them off shores and into the open seas. The stallion forced to stay afloat on her inflated body.
Then, trouble came when she started to spring a leak in the form of farts. In a desperate attempt, the stallion uses the only thing he had to a cork to plug up the leak. His Cock! Thrusts his cock up her stopping the leak. As long as he remains erect and in her, they should be fine right? However, when the seas are rough and stormy, that is easier said than done. The waves keep tossing and turning them, his cock keeps shifting inside, arousing the stallion and mare. Eventually the stallion came to a climax, cumming hard inside of the mare and inflating her a bit more. After a short moment of euphoria, OH SHI-! realizing his rod is now limp and isn’t plugging his partner’s rear hole anymore.
PFFFFFFBBBBTTTTTTTT~! into the distance farting and spraying cum like a hose.
