I come to you with a few different ideas with quite a bit of room for customization:

Pokemon RP

My character is a gym leader - a woman in her mid-20s who's been at this for a while and is getting a bit bored of it. Wanting to seek adventure again, she pulls a party together and plans to head out, but the road to adventure she's trying to take leads her to unexpected places. Perhaps a Psychic or Ghost type messes with her mind. Perhaps a Fighting type just takes her. But, before she knows it, she finds herself a plaything for all different species of Pokemon - whether she's mind manipulated to enjoy it from the start or starts out horrified and ends up loving it, I'd love to see where her adventure takes her. I was thinking she would be a Fire type gym leader - if we wanted to use the newest region as the setting, Paldea doesn't have a Fire type gym but I'm sure we could either find a good place to add one in or replace one of the gyms that already exists with a Fire type gym. Kanto, Hoenn, Unova, and Galar all have a dedicated Fire type gym and I could especially see my character being sick of living on Cinnabar Island out in the middle of nowhere, but those give us ideas of settings we can use without having to create an entire new world from scratch. There are probably Pokemon that wouldn't make sense to include, but with roughly like 1000 of them now, I'm sure we can find a good mixture of ones we can place in whatever region we choose to work with.

I can also play a male gym leader for it, which comes with an added option of some soft feminization if that's something a partner would be interested in. Not like bimbofication, but making him into a cute girl, basically.

Monstrous Partners RP

This one is an idea that's open to a lot of things: One thought is an elf who is trying to sneak in and stealthily take down a warband of orcs, but ends up getting caught and punished in the way they most see fit. Or a young woman sleeping soundly in her bed being visited by a tentacle monster in the middle of the night? Maybe an alien lifeform looking for a human woman or some type of fantasy race visited by a non-space tentacle monster. There's a lot of room here for discussion whether my character is male or female.

Same-Sex Affair with an Authority Figure

My original thought for this was playing a young woman working in the kitchen of a castle who becomes the object of affection of her queen - the king is often away or busy, so she seeks a relationship with this beautiful servant who spends every moment in her thoughts. As for a way for things to get started between them, perhaps the queen is holding a feast for various nobles to come and visit and talk about the news and gossip of the kingdom; the king is gone and the queen tires of entertaining these people in his stead. While the kitchen staff serves dinner, her eyes pass tiredly over the crowd until they fall on my character - a servant girl that immediately grabs her attention. The queen and the nobles eat and talk until dinner is done, but when a moment arrives when the queen can finally sneak away, she makes her way down to the kitchens to find her - wanting to speak to her, to be around her. And she visits often after that, until things start to develop between them - an affection and attraction that the servant girl feels she shouldn't have, but that the queen deeply wants to stoke in her.

But, it can also be done as M/M pairings or pairings in other time periods, such as professor/college student, boss/employee, things like that.

Kinks: Public, risky, impreg, oral, anal, feet, cum on clothes/body, seduction, cheating, creampie, mind control/manipulation, dubcon, noncon, soft feminization, probably others I'm forgetting

Limits: Vore, gore, bathroom stuff
