Cursed with tentacle armor! (GM LF Female adventurer)

[Sethala]

First, a reference pic for the idea I'm thinking of (though not necessarily this appearance for the armor): https://gelbooru.com/index.php?page=post&s=view&id=6054745

I've always loved the idea of a character wearing armor with tentacles that tease and torment her as she tries to find some way to get rid of the thing, getting into all sorts of lewd trouble as she goes.  Of course, the armor has its own ideas; somehow, it can give her orders (perhaps it can talk, perhaps it can give the wearer brief visions in her sleep, or some other way...), and if she doesn't obey, it knows just how to torment her and make her regret her disobedience.

There's plenty of ways this could go, but ideally I'm looking for someone that's a bit of a switch; tormented constantly by the armor, but willing to get into her own lewd situations and perhaps grab another girl to "share' the armor with for a night.  I can run this as a freeform game, or I could work with a system such as PF2 or D&D, depending on what my partner wants.  I could also do a small group game, if there's enough players interested.
