Upon reflection, I think the unifying factor in my taste in erotica is premises that can reasonably be characterised as "overengineered". Forty thousand words of geopolitcal worldbuilding to contextualise one sex scene? Check. Nuanced exploration of what a magic system revolving around the author's odd fetish implies for civil engineering best practices? Yes, please. Deep dive into what evolutionary pressures could conceivably produce a cock that does that? Don't mind if I do.
(In some cases it can even elevate kinks that are kind of nothing for me otherwise. Like, I'm not super into hyper cum, but when I can tell from how it's written that the author has actually done the math on their OC's fluid output? That's hot.)
I'm not going to Google it because I don't want to see the results, but is that in fact the community's consensus term for it? Were "ultra" and "mega" in the running in the Usenet days, or did everyone land on hyper early on? Is there a het/queer split on name? What's the threshold for being "hyper?"
"Hyper" is pretty settled nomenclature, at least in English-speaking fandom spaces, and has been since at least the early 2000s, but in my experience there's no consensus whatsoever on what the threshold is. With respect to ejaculation, for example, some folks will call pretty much anything in excess of realistically plausible output "hyper cum" (so, e.g., a character producing enough to fill a coffee cup would qualify), while others will be very insistent that it's not proper hyper cum unless there's mass property damage involved.
If it helps, sometimes the people who see hyper as only enough to go past human limits, (coffee cup) view it that way because the kink only starts when their mind stops thinking it as real.
Think of how the point of porn for some people is 'gratification without setup or consequence' Whether it be not having to worry about finding a pizza person willing to take payment in sausage, or whether it be making the perfect chocolate lava cake (food porn) or booking a trip at the right Time of year (scenery porn) or the logistics and cleanup afterwards for any of these.
Things that were gross a second ago stop being gross and start being hot because it stopped being something you can reasonably come across and have to worry about the consequences for, and now imagination is taking over.
Once that OC starts pouring lattes, you can choose to start thinking about how that works both biologically and socioeconomically, but the move from 'realistic' to 'fantasy' is often important, especially for people who experience their fetishes irl in a mundane setting and like to separate the two.
Like working in a sperm bank and being completely unaffected by the irony because you only think it's hot if someone is capable of filling a beer mug.
