Premise:
It's been 1000 years since Luna usurped and sealed away her older sister Molestia. In that time she has had severe censorship laws passed, making it illegal to so much as talk about anything obscene. Meaning foul language, pornography, sexually explicit images, or even mention of the correct medical terms for certain "obscene" body parts have been outlawed.

Dusk Shine, one of the top students at the School for Gifted Unicorns, is recruited by Luna to track down an Obscenity Terrorist group known as COM(Children of Molly), as Luna suspects that the group may have a base somewhere within Ponyville and needs Dusk's help to find them.

He immediately agrees and heads to the town with his assistant Spike, upon arriving he meets and befriends another unicorn named Sunset who invites her to a private party taking place at midnight. Seeing this as a chance to gain some more information on the town he happily agrees.

The party turns out to be a special ceremony for the COM organization, to reveal that they have uncovered a special journal left behind by Molestia herself. Which reveals that in order to restore Equestria to its original state of a land of lust, they must awaken six powerful gems known as "The Elements of Debauchery".

Things take a turn for the worse during the ceremony when Dusk and Spike are soon dragged into aiding the organisation in their quest to abolish the censorship laws and bring Equestria back to it's age of debauchery. Will Dusk and Spike be able to take down the organization from the inside? Or will they surrender to their sinful desires?
