The Dark Pony
Anyone who downvotes on the content alone: I get it, you want to think of the ponies as “innocent” and “pure”, that’s perfectly understandable, and there was a time I did too, but between the high amount of buttplay (and close-up butt shots of Twilight and Fluttershy) and Pinkie’s Potty Emergency I couldn’t keep them out of my fantasies any longer. (Of course they added fuel to the fire with the whoopee cushion as it implies the ponies canonically fart off camera)
But if you dislike it that much, just filter out the fart tag. No one’s forcing you to be exposed to this stuff.
