A friendly get together at Twilight Sparkle's crystal abode winds up with only Half of the Elements of Harmony being able to attend. And wouldn't you know it? The two proudest elements, Applejack and Rainbow Dash, are left all the more uninhibited from bragging and betting who the better mare is. Twilight oddly enough, does not help the situation.

Three mares, one challenge, and a dirty price to pay for losing. Which pony has quite literally the most intestinal fortitude?

Kinks Ahoy: Scat/Scat Smearing/Very Light Coprophagia, Emphasis On Wiping In Conventional and Not-So-Conventional Ways, Rimming, Cunnilingus, Face Sitting, Desperation, A Bit Of Humiliation, and Some Farting.

Also what is probably a poor understanding of physics on my part.

A request fulfillment. Hope you enjoy!
