Rarity prides herself on her commitment to cleanliness. Everything from her appearance, to the way she acts, to the state of her various places of business, all of it paints the image of an immaculate mare committed to the very essence of cleanliness.

However, Rarity also has a rather dirty secret, one that would completely shatter the pristine image she had cultured for herself. For deep down she was far, far dirtier and nasty than anyone could have ever believed...

Be warned! This story contains diapers, heavy diaper usage (messing), enema use, and much worse. This could very well be the most disgusting thing I have every written, and I regret nothing.
