Sexual terminology "power bottom"?

[Andy French]

What would be the terminology for someone who is getting fucked, and fucked hard, but they still demand that you fuck them more and fuck them harder?

The closest I think I could come to this was the term "power bottom", but It's a term used for gay sex, and I'm not exactly sure if it's what I'm looking for.

Kinda like a dom, but they are the ones getting fucked and just can't get enough, always demanding more and harder no matter what you give them.

Is there a term for that?

Topping from the bottom?

The way I hear it nowadays, "power-bottom" isn't exclusively reserved for gay sex anymore. I indeed have heard that term used to lable exactly what you describe, someone taking the more 'submissive' or 'bottoming' role but absolutely wanting more of it. This, for example (NSFW, pokemon porn)

Of course, it is possible for one to take the role of being -fully- dominant, -and- wanting to be fucked hard. The difference is a little bit in attitude, or more specifically, if the one "being fucked" is explicitly in -control- of what is happening, or if they are just nudging and encouraging enthusiastically. There is some fuzzy grey area. At least...I think. I dunno for sure, I'm not an expert, this is just the understanding I've sort of "cobbled together". x3

From what you describe @Andy French it seems the person would just be insatiable and enjoys being pounded hard. So perhaps just go with "insatiable" as I don't see it as being necessarily BDSM related behaviour.
