“I’ve learned the hard way that you should never assume anything is a free sample without asking first, if there’s no sign saying one way or the other. Just one gulp of root beer and YOINK! I get dragged off by the tail and told that I’m going to be both an example and an advertisement. They say that it’s going to be a long shift to pay back what I drank from that mug, and despite my protests and struggles my rear gets padded up thick before they pull a poofy costume down over my body. Finally I’m shoved by my crinkly butt back to the front where everypony at the festival was passing by.
 
At first I go along with it, carefully turning myself as ponies passed to avoid letting them see what was under the skirt. But one minty white unicorn just had to get curious and look at me from behind before bursting into a fit of giggles. At that point I panic and try to gallop out of there, but I’m swiftly restrained by the same group as before within seconds. They slide my forelegs through the handle of the mug-like costume, which tightens down to bind my legs over my chest.
 
I flop into a bent over position, my diaper even more visible than before. I’m helpless now to all the staring, photographs, jokes, teasing, and the occasional rump pats that make my cheeks burn. Despite everything, I actually start enjoying it after a while…maybe because I’m getting revenge. Everypony was stopping to look at me, and not one of them was even paying attention to the drinks vendor!”

I dunno, I’m kinda into the body diaper idea.

@Dreamsicle

@Wing8492  
It doesn’t, it’s just colored the same. XD

Hah, looks puffy and nice
