I was quite reluctant to post a fetish-based story up here, but after some reassurance from other users to not be ashamed of my fetishes or applying them to ponies, I decided to write this story for here. It'll follow my more particular style, and hopefully not stand out too much, except to those seeking them out. (I am still a little shy about it)
In short: The ponies wet themselves in my style of the fetish, and one of them develops an interest in it. There will be at least one scene for all of the Main 6, in pony form, wearing some sort of outfit, plus one for the human Rainbow Dash, because she hasn't been done in this story.
Please don't make a big fuss if any of the ponies seem out of character, or if any of the scenarios seem unlikely.
Contains: Omorashi/watersports. Not recommended for anyone who doesn't have this fetish. If you don't like it, please ignore it and read another story. If you do, enjoy. This story is meant for everyone who ever wanted to see this particular kind of story but was never able to find one. Also, despite the fetish-based material there is no explicit content, so if you prefer for this fetish to be mixed with that, maybe this story isn't for you.
Update: Because this is my first time, the earlier chapters are lower quality, but I tried to put more in the last few chapters. So, don't be too disappointed by the low quality of the early chapters, it gets better.
