Is there any specific name for this kind of thing?
While I love objectification, for some reason the idea of a noble or royalty being the one to own me just makes it 50 times better ~

kinda like a master/slave dynamic but more romanticised huh

Not necessarily. Can be, but can even be less romantic.
Say a king enslaving a slut who tried to cause a rebellion, or a noble kidnapping a pretty looking commoner to become their possession.

I get this, totally. Maybe I just have a thing for power dynamics in general, and them being enforced / subverted. Couldn't tell you what a proper name for it would be, other than a power dynamics kink of some kind.

You probably don't need a new name for what is essentially "objectification + classism".

I'll pass on the factory owner in a suit.

But monarchy is sexy.

Different class, same concept.

There is an enslaved royal tag in search

That is hot, but I was talking about the other way around

That's the opposite of what OP asked for and also not the same kind of thing (attraction to a thing vs. presence of a thing).

(edit: I need to type faster...)

I don't know of a way to do it so just imagine that I'm showing the Megamind "presentation!" Meme
Like sure at the core it's effectively the same but a hot fantasy prince will always make me hornier than Trump, don't get me wrong, Trump is THICC but fancy prince clothes make me drool.

Like this?

It's still just "objectification" with a specific flavour. No real need to call it something else, just like how strawberry flavoured ice cream is still called ice cream. The flavour doesn't change what it is, and you can always search for the flavour along with the kink.

I have masturbated before thinking of Elsa ordering me to give her a heir

That dialogue at the end it's so hot for me

Nah, I like the other way around with the enslaved royal scenario too. It's so much more fun to reverse the power dynamics than to play them straight, it makes the scenario more taboo and novel when the normally powerless are powerful and the normally powerful are powerless.
