Fluttershy is a shy girl on the outside but on the inside she is a kinky girl who loves wetting herself. She can pee in her wetsuit without shame, but sometimes she goes to the beach in the outfit she wears underneath and, if no one is watching, she will pee in her shorts and take absolute pleasure in the warm wetness spreading through her skintight shorts and flowing down her legs. Afterwards she'll go for a little swim in the water so anyone she runs into on the way home will think she just got wet with water and not suspect she peed herself.

I was meaning to do this edit because I've written stories about her wetting this outfit that is not seen in the show at all. (I drew it over her wetsuit) But, I won't be taking any outfit-changing requests, this took a while to do and I attempted another one before this but couldn't make it work.
