I dislike femdom as much as any other, but the scene was fine. Tia was in a power position because MC was recovering (and she is stronger than him anyway), her actions and dialogue are consistent with her feelings of falling for that young asshole and the banter is fine because MC gives as good as he gets and doesn't surrender.
There is no "daddy" talk. Both Tia and Darla were in love with Biten. This isn't your "male-rolemodel was a deadbeat who disappeared" kind of story. His good relationship with his wives is mentioned throughout the story and it's still relevant.
There is no "cuck" talk. Don't misrepresent the dynamic by projecting.
The banter is supposed to be offensive, from both sides:
- Your father was better.
- Nah, your pussy isn't that good anymore.
I wonder how some people managed to make it past the prologue..
Since when does the game attempt to protect MC's and Player's feelings? It's a huge give and take from the get go.
MC gets ridiculed for 3 chapters straight, ends up being an alchemy genius which requires 1-2 more chapters to understand what it means.
MC gets ridiculed and beat up because of his soul color and overexcitment, ends up beating the shit out of seniors.
When everyone gets his awesome forms, all MC manages to do is fart. Then he gains some new context and oneups everyone.
Nothing that happens in this VN is familiar. So don't even try to suggest that certain fetishes only fit "other" genres and not the typical harem story, because this isn't the typical harem story.
MC wants to fuck Darla, but peepee doesn't work.
Tia tries to drug MC who acts like an asshole in class.
Naomi is a tsundere who leeches power from MC.
Mimi is a sex-starved psycho.
This is the good old "community can't handle certain fetishes" thing despite the developer not breaking any "covenants" with the target audience and despite the relationship being consistent with how the characters are written. So just add a warning for fetihistic sex before the scene with a "yes or no" choice and move on.
