Oooh. Interesting hehe. So many possibilities... How about a group YCH with a popular cartoon/anime? Could have slots featuring the main characters (or main villains) doing vore, keeping someone underfoot/forcing to clean feet, bondage, blowjobs, sex etc.

Possible Cartoons and Poses

Gargoyles:
Goliath (Foot Worship/Sex), Demona (Bondage/Using Spell Book To Dominate or Hypnotize into a Slave), Brooklyn (anything), Lexington (Foot play/Sex as the bottom), Broadway (Vore, possibly Oral and Anal), Hudson (anything), Bronx (Vore)

Teenage Mutant Ninja Turtles:
Leonardo (anything), Donatello (Bondage/Gadget Experimentation), Raphael (Bondage/Foot Worship/Sex), Michelangelo (Foot Worship/Blowjob), Splinter (anything), Bebop (Vore/Blowjob/Foot Worship/Spit Roast with Rocksteady YCH in the middle), Rocksteady (Vore/Foot Worship/Blowjob/Spit Roast with Rocksteady)

Beastars:
Legoshi (Vore/Sex/Foot Worship), Louis (Slave Master (YCH is on a collar and leash held by Louis)/Foot Worship/Sex), Haru (Sex), Bill (Vore/Foot Worship), Gouhin (Sex/Foot Worship/Slave Master), Shishigumi Chief Lion (Vore)

(and as a more obscure cartoon but one I think has potential)
Hot Wheels Battle Force 5:
Captain Kalus (anything), Krocomodo (anything), Sever (Foot Worship/Vore), Hatch (Bondage), Grimian (anything), Zemerik (Slave Master/Bondage), Zug (Vore)

Other ideas could be from computer/video games. Here are some that may be fun if any inspire you.

Animal Crossing New Horizons
League of Legends
Super Mario franchise
Legend of Zelda
World of Warcraft
Overwatch
Undertale
Five Nights At Freddy's (FNAF)

surprised there are no other comments yet. I guess I will make some more with ideas not related to known characters, and instead just for people's fursonas/characters hehe.

Locker Room: A group of players and their coach on a sports team celebrating a win in the locker room after the game. Could include any kind of sex, bondage, smelly/musky equipment sniffing, vore, forced foot worship, gagging etc. Possible slots could be the coach, players on the team, water boy being tormented, a player or two from the losing team, and maybe a sneaky fan trying to sneak a peek.

Eating Contest: Players sitting at a hotdog (or some other food) eating contest. Can include food stuffing, vore. Possible slots could be the people in the eating contest, a judge, waiter bring more food, empty chair or chairs where previous competitors were (but have now become food, either a belly bulge, part of their body hanging out of another competitor's mouth, being grabbed to be eaten etc.)

Carnival/Fair: A carnival scene showing popular food and game stands. Can include vore, bondage, transformation, slave/master, paw worship etc (very flexible). Slots could include a carny running each stand, carnival guest visiting/using a stand, dunk tank (character that's bound and/or gagged on the dunking seat, with another character in the tank ready to devour them if they fall), candy apple stand (character shrunk down and dipped in a candy coating), ring toss stand (rings are thrown onto paws, but the paws actually belong to a character bound behind the stand and forced to sniff/clean the carny's feet, another character is bound in latex/a giant plushie who is advertised as the top prize), whack-a-mole (character who is being knocked out silly/dizzy by a hammer, another character sticking out their tongue/taunting the character playing the game), side show attractions (character as a hypnotist, character as volunteer from audience now under their control, character as a lion tamer who has failed the "stick your head in a lion's mouth routine" and has more than just their head inside now)

Dungeons and Dragons (version A): A group of 4 to 6 players and a DM get together and have a tabletop campaign session. Can include vore, hypnotism/mind control, paws/feet. Slots could include a smug/dominant looking Dungeon Master, a character inside the Dungeon Master's belly having failed their saving rolls, a character laying/kneeling under the table taking care of the DM's feet for failing against a Suggestion or Dominate Person spell, a character rolling some dice with a nervous look, a character holding/looking at their character sheet, a character with their feet up on the table eating/drinking something.

Dungeons and Dragons (version B): Characters are literally in D&D, dressed as their party roles. Can include vore, sex, hypnotism/mind control, magic, paws/feet, bondage. Slots/scenarios could include characters in combat with monsters, character being swallowed by a monster, character having sex with an enemy monster or party member (willingly or unwillingly), character being bound in rope and gagged by a monster, enemy monsters celebrating after a victorious party wipe using the defeated characters in kinky ways (and maybe someone betrayed the party and is celebrating with the enemy). Possible enemy monsters could be kobolds, dragon, gnolls, werewolves/wererats/wereboars, orcs, orgres, gelatinous cube, mimic, goblins, minotaurs, bugbears, trolls, bandits (could be more YCH slots), wizard (could be another slot for YCH)
