My take on the whole "forced content thing" is:
TL;DR: The forced situations are part of the story being told, not just a rape fetish or whatever.
Tabi is a semi slave from a race that's 1 -
naturally lusty and 2 - viewed as "whores, the lot of them". The rapes and gropes and etc are justified in the context of the game. You may not like it, but if Nverjos makes that optional or removes it from the game, the premises the universe is built on are weakened.
Tabi is constantly threatened with rape and violence, and I think it is a good thing
for the game. It shows exactly where she is on the social ladder: at the bottom. And there are stuff that happens to people at the bottom that they can't control, they can only choose how they're gonna cope with them. Even her uniform is altered to be more slutty, per request of the princess, who loves her. The other tainted female at the castle fucked every single male there, including Sage, Tabi's brother.
The first rape, at the lake, was something that Tabi suffered to save Lili, who's her princess and her lover. She can hate it or enjoy it. She was a hero, saving Lili, but she's powerless to do anything else. Thankfully the guys were arrested, but we don't even know if that's going to last. It's awful, but it could happen to someone that's not even considered a person, just a fuckdoll for other Fae. Tabi suffers other violences, though not that severe, by not being able to drink at the tavern, not being able to enter the library, except with explicit authorization from the Royal Family, people being rude to her for no reason at all, etc.
"Not being able to complete Brothel Peeping besides for showing yourself off for a perv" is something that is avoidable. You just have not to invade people's privacy, then you don't show off to a perv.
The human world thing is in a city devoted to the Goddess of Lust, negotiating with another tainted, who's lusty too, and you don't even need to do sexual stuff for getting it, so meh.
Tabi is very smart, resilient, strong and tough and, in opposition to corruption games, the fact that people constantly abuse her actually
outlines her toughness. Smart people can be abused, too. She was born in a very cruel situation, she suffered her whole life
and she is still a pretty positive person, that's able to love and help other people. This is different than being an air-head that gets in dangerous situations because she's too dumb to act in a different way.
