The game usually references real stuff, so I can only assume that this one is real.
What is the name of the referenced porn game where you are a trans woman detective that impregnates its clients?
From chapter 5 in power vacuum:
That pic is 100% from Haramase sim. Just booted up my game and found the chick in the pic. Can't remember how to get that exact scene (from player's home) so I just took a pic at the bank where she works. Also took a pic of Ootori (chick from your original post).
Game is definitely Haramase Simulator. Have spent too much time in that game to mistake it for something else.
