This is the only occurence in the game, I'm really not a fan of race play and I love this game, don't worry the rest is safe.
I do believe that "blacked" feels a bit out of place since the game is mostly about getting dommed by futas and race is litterally never mentionned except for this. I think the VR headest is just filled with random sissy hypno stuff, hence race-play stuff since it's not unusual?
