That's something that has been brought a lot on their Itchio site.
You get all kinds of XXX-lover perks, or even the critter-lover perks, but every description reads as if your character hates it.
I think the idea is to appeal to humiliation fetish, but is not handled well, or Maj isn't bothering in branching text for options.
Pity, because instead of having more content (which lately feels somewhat rushed and lacking), having several types of endings would count not only as more content itself, but also would appeal to more players. And adding some bits of alternative text is pretty simple, since it doesn't requires hours of hard coding (neither new art).
Unfortunately, talking to Maj is like talking to a rock.
No matter how well you explain, how much you're right, how many others also ask for the same, he just says "no" and that's it. They're only in this game purely for the cash, which it's perfectly fine but at least they (or he) could listen a bit more.
(to be honest, and this is my personal impression, he sounds kinda smug. Dunno, maybe he's jaded of all the internet trolling. I'd totally understand that, more in this... environment, wouldn't judge that.)
