Looking for a dom female to play two characters in a love triangle RP

I had this idea quite some time back, but I deleted the original thread because I wasn't sure if I could make this work quite as well with the new rule that we can't have teens in sexual situations anymore.  But I think I found a way to make this work and would love to try it again:

A young man has had a pretty rough life, but there is one thing that's a major highlight, his childhood friend who has always secretly had feelings for him.  But while he's at home, which also happens to be on the very day his friend has finally decided to confess her feelings to him, a demon woman appears before him while he's taking a shower and forces herself onto him, essentially making him plant his seed inside of her in order to make her his official soulmate.  Needless to say, this complicates things, resulting in the human woman and the demon constantly competing for the man's affection while other demons target the demon woman along with the human since, again, due to her forcing him to cum inside of her, he is officially her 'property'.

So obviously, the idea is that you, my partner, would play both women competing for the man's affection, essentially having them both form a bitter rivalry but will be forced to work together every time another demon tries to take him.  We could discuss more details in an Ecchitext, though since the presence of other demons would require action scenes, there is one thing I would appreciate, and it's that you don't make the main demon woman too OP.  I'd like there to be at least a little tension during those scenes, like, the possibility that the demon woman could potentially lose. (You can tell I'm a shonen fan) Only other thing to take into consideration, as I've pointed out before, I don't always write long posts.  At best, I could consistently find enough material for one full paragraph if you really need me to. (There was one RP I did a while back where I did manage to pull it off, but it's not entirely my forte.  I kinda have the belief that RPs and published stories are two different things) But I am often more comfortable when my partners don't expect more than a small number of sentences per post, though I will avoid one-liners if you'd prefer.  I know a lot of people aren't big fans of those, and it's not too often I find myself unable to come up with enough material for more than a single sentence.

Anyway, yeah, if you're female and feel up to playing a dominant role, hit me up and we can discuss further.
