@mommunism An adult male that brings an underage prostitute home to "help" her instead of immediately calling the police isn't a normal half-decent person, he's a human failure. Don't kid yourself for a second that there is any excuse to bring a girl like that home other than sexual gratification.
What makes this manga and "I shaved..." different is that here the protag straight up fucks a girl, showing that at least he sees her as a human woman, whereas in "I shaved..." the protag gets off on what a moral hero he is for not raping the girl - while keeping her as a pet/houseworker. It's literally a BDSM fantasy. The "smut" tag on these titles should be reversed, as hypocritical BDSM fantasy is ten times more degenerate than vanilla sex.
Also, why don't you ask yourself why the girl in "I shaved..." is a super hot and super moe high school girl, instead of a 40 y.o. crackwhore with rotten teeth, or a gay twink. Look in the mirror and try saying that you would praise that manga just as much if it was about those characters.
