At the beach, Fluttershy really has to pee. When she tells her friends this, Twilight says she could always go in her wetsuit. Fluttershy blushes and says “I couldn’t.” Twilight tells her that people pee in their wetsuits all the time and no one here would think badly of Fluttershy if she did, though in the end it’s her choice. After a moment’s hesitation, Fluttershy begins peeing her wetsuit. She can’t believe she’s deliberately peeing herself in front of all her friends, and is understandably a bit apprehensive at first, with the sound and smell of her pee clearly noticeable, but her friends’ lack of disgusted reaction or making fun of her helps her relax and enjoy the warm release. Perhaps more than Twilight expected her to.
 
This was her first wetsuit wetting - but she knows it won’t be the last!
 
I tried a different effect with the text this time. Hope you like it, and there might be one or two more on the way.
