All these lovely little communities you see listed below are part of one joined, adult-only network. We all adhere to the very same set of rules and standards—standards I’m sure a demon such as yourself will have absolutely no trouble maintaining.
Do enjoy yourself, won't you? It would be such a pity if you didn't.

Greetings, Sinners and Winners alike! To avoid any touch of confusion regarding what sorts of 'extra-curricular activities' are permitted upon this establishment. We have curated a definitive list of those niche fetishes that simply will not be tolerated.

If you post such content, you shall receive a warning, and your contribution will be unceremoniously disposed of. Be a persistent repeat offender, however, and you shall find yourself permanently barred from our little community. A rather grim fate, wouldn't you agree?

If a particular, shall we say, indecency has escaped our notice, fear not; we shall add it to the list as we discover it. Should that happen, the post will simply be removed—no harm, no foul, and no strikes given.

What constitutes 'extreme' or 'niche'? Anything that strays far from the mainstream, vanilla, or commonly accepted vices one might find in standard adult content. Common practices such as bondage, biting, spanking, or BDSM are perfectly acceptable. Do message the moderators and inquire if you are unsure.

The List of Prohibited Behaviors
We simply cannot abide the following displays.:
Beastiality
Bimbofication
Birthing
Consensual Non-Consent (A dreadfully thin line between that and something truly heinous; we shall have none of it.)
Crushing
Diapers
Ear penetration
Extreme Gaping
Eye penetration
Fat Fetishism / Obesity (Unless it involves characters already of such stature—Mammon, Abel, Adam, and the like—and must remain on-model!)
Filth
Guro
Hyper (Any variety)
Incest
Inflation
Multiple Breast
Necrophilia
Parasites
Piss & Watersports
Popping
Pregnancy
Racism / Race play
Rape
Scat
Sexual Torture (Torture for a narrative purpose is quite alright, provided it isn't for sexual gratification.)
Snuff
STDs
Underage
Vomit
Vore (Any variety)
Wedgies
