ExotikTwilight's Preferences

Modern: Legalized slavery? Criminals bought off a prison auction and turned into BDSM pornstars?
Resident Evil based: Bio hazards, unethical shady corporations, sex crazed mutant outbreaks, espionage and infiltration?
Cyperpunk based: Dystopian high tech world, also with unethical shady corporations, governments that use mercenaries and black ops, cyberized and synthetic bodies, espionage and infiltration?
Paranormal based: Sex fueled rituals, magic, demons and ghosts and things that go bump in the night, cults?
Modern like fantasy: magic tech replacing modern tech. Dungeon portals, nobility, adventuring and quests.
Set in space: mercenaries, adventurers, alien worlds and creatures, daring missions and drama?  

BDSM/Bondage
A huge one for me, this will be used heavily. Everything from simple tape to elaborate gear, contraptions, and full body enclosures. Fun describing how the dommme binds the subs, how the subs moan, squirm, and struggle themselves well into being sweaty and aroused. How the subs bind each other and writhe in helpless delight. Includes all related toys and goodies.
Gags
Another huge one. From simple over the mouth to filling their mouths and layering it on until they can barely make a sound, let alone something sounding intelligent. Typing out how their muffled speech sounds, and them trying to figure it out, is fun!
Clothing
Tight Clothing and Latex. Just like in anime/manga/webtoons, clothing that clings to the body's shape. Can even be latex clothing, colors and layered to 'look' like the regular attire.

I know these following kinks are more out there, so I'm ok if they're no go's.

Incest
Offspring of the doms and subs/switches being introduced later on as subs and switches, once they reach adulthood (18 years old).
Tough and Rough
Characters will have great resiliency/resistance to damage. Things that would be lethal otherwise instead only hurt alot (and can also cause pleasure for our pain sluts!) with nothing more than incapacitation or bruised/reddened skin. Things like beatings, heat/cold, acid, poison/electricity, drowning/asphyxiation, etc. Can also be scaled back to less extreme pain/impact play.
Inflation
Pussies/stomachs/wombs can get filled with fluid/goo/etc and expand, up to a certain point.
Cum/Milking
Milking breasts and pussies (and cocksif included) until they're dry, either by the dominant, villains, or other creatures. Large volumes of milk and cum, which would be scented and flavored.
Slightly Different Biology
Tongues that are longer, larger, more muscular, to allow subs to pleasure eachother and their dominants better. The ass functions as a rear/secondary pussy. Exactly what this entails can be determined.
Alpha/Omega, Dom/Sub Verse
This can be however we'd like it to be, it's more to explain a natural dom/switch/sub dynamic in the setting.
