Very poor characterization, the characters are one dimensional stereotypes full of clichés.
I can't tell the difference between the two supporting female characters, they're both dumb bimbos who laugh with a "heehee" at everything, cheat on their partner, like being sluts and love big cocks. Oh and they like dressing slutty of course, who could forget that.
Likewise the male characters are just abusive raping assholes with big cocks, even the father, Katie's boyfriend being the exception. Alas for Katie she doesn't get any scenes with the boyfriend so there is little point to doing a pure route. You just get scenes of Katie being understandably mad at her abusive boss.
Katie herself only differs from the two other bimbos if kept pure, otherwise being raped by big dicks turns her into a cock addicted idiot.
Didn’t really care about the story since none of the characters were interesting, nothing happens in the game if it’s not related to Katie getting abused or not. She doesn’t seem to have a life outside of her new job, no friends besides her boyfriend, no hobbies, nothing that isn’t a plot device for Katie to be abused. And there's barely any inner dialogue to go with her bimboification.
A good corruption story relies heavily on the character being corrupted as well as the source of the corruption, and the game misses the mark on both since they're all underdeveloped characters.
Of course this affects the sex scenes too, they’re rather short, with little build up or inner monologues, and have to be carried mostly by the CGIs.
Sadly, while the render of the characters themselves varies between decent and good, the backgrounds are usually on the poor end, often too dark to see anything or simply a poor representation of the spaces they are supposed to be. And the scenes being short does mean they don’t use a lot of pictures.
Overall this is just poorly written smut, but at least it’s not utterly tedious to play.
