I mean, the devs aren't even paid for their games (because the games are usually free) but to push them to make more games and continue the ones they started. It isn't the same situation than fanfics writers who are commissionned to make a lewd story on Tifa, Samus or another character. Devs can do what they want, we pledge in the hope they will continue their games, but they are totally free not to do it. The fact this game is continued, fun (I like the long texts, it immerses more in the game than just "he's so big I love it"), with great art without dropping quality (looking at you Kingdom of Deception), good writing, and the character's moral degradation is, even without much sex, already incredibly arousing in my mind (the brainwashing or pet scenes, ooof).
