I like games with stories similar to this. The sph and sissification are some fun RP, but the forced cuck route is disappointing to say the least.
This is like saying Once in a life time isn't about incest...Hello there. The game is not BNWO focused even a significant portion of the discord voted to include BNWO elements more in the past.
Only one of the characters is into BNWO only (Clara). There are interracial elements yes but the black men are not degredated into BBCs. Mr. Brown, Mr. Douglas and Darius have very distinct and opposing personalities. Especially Mr. Brown as "the black man" of the story has different personality than what is default in the said genre.
Even when MC reads a BNWO blog in-game he dismisses it as some people's kink.
