While watching the Buckball game with Celestia, Twilight wore a sporty outfit for the occasion even though she wasn’t playing. She had to pee really badly but didn’t want to miss anything, and ended up peeing herself. She was a little shocked and slightly embarrassed, but not overly so, and sat in her puddle until the end. Celestia didn’t mind, of course, besides, even she’s wet herself on occasion and laughed about it.
 
I couldn’t resist doing another one, I just got this image in my head of Twi sitting in her puddle after wetting herself and I wanted to do something with it.
 
I am a bit rusty at pee edits though, not to mention drawing outfits on them, it’s been a long time…
