Ostensibly, Rarity is one of the cleanest and most ladylike girls you'll ever meet, who hates getting dirty in any form. But she secretly loves many forms of it, and does so when no one is around. No one who knows her would ever guess what she does on her spare time.
Contains: Fart, omorashi/watersports, scat, and mud (though the last one isn't a fetish for me I do love it nonetheless). Also, some light spanking, and bit of fanservice to those with a foot fetish.
Another fetish-based story, using all of my fetishes in a very different way from the Extreme Fetish series. Please don't take too seriously, and if this stuff offends or disgusts you, move on to another story, for it is not my intent to offend you, only to appeal to those who like this stuff.
