(Originally published on Fanfiction.net and Deviant Art. Based on a comic sketch by MatiasDiplinLps on Discord, in turn inspired by Potty Training the Princess by JAC59COl on Deviant Art. Contains mild flush and toilet vore, as well as mild potty humor. Rated Teen as a precaution.)
When Shining Armor happens to need to go to the bathroom, he decides to use it as a teaching opportunity to show Flurry Heart how to go potty like a proper pony. After all, children learn best by example.
However, Flurry Heart soon grows bored of sitting on her potty chair and decides to have a little fun. When the little one sees what looks like a treat, she tries to grab it, not realizing what it really is.
Before Shining knows it, he's being flushed down the toilet by his daughter! And Flurry doesn't seem to realize what she's doing to him. How will it all end for father and daughter?
