_“Hehee, how’re you liking this new pump I got, Twinnie?“

“Mmweh, ah, well, are you sure it’s working? I mean, you’ve been pumping for a while, and as far as I can tell only my cheeks have been puffing up – and not even the fun ones. You think it might be a bit broken?“

“Oh, I’m sure it’s working just fine, really… try leaning back a bit, maybe you just need to see your belly more~”

squeak~

“W-what the…”_

Minty came home one day with a brand new air pump, so of course he was more than eager to get to testing it out on me! Though considering he’d already been working it for a good while and my belly was still the same size after so many puffs, can’t blame me for thinking he might’ve bought a bit of a busted one. Of course, that was before I noticed that odd sensation of squeaky puffy rubber on my back…

What kind of pump did that silly unicorn find!?
