Just a heads up, GET AON'S MOD!!!! Without it this game is a slog to play, which is unfortunate because it has one of the best content you'll find here.
That said, very few games reach the insane levels of depravity this one does, it's definitely one to go if you're feeling the naughtiest.
Story-wise, it's as bland as you can go. Characters won't have any personality beyond their looks, age and the fetishes related to them. No plot whatsoever, neither any kind of interesting dialogue past the minimum required to be playable.
In spite of that, that's not what the game is supposed to be. It excels in how many girls it can throw at you, how many fetishes you can juggle around in a scene and all the disregard for common sense you would want in bombastic pornography. We're talking about obscene sexism, incest, exhibitionism and all the stuff you'd expect (and also what you don't!).
Regarding the visual quality, it's not the best you could get, you'll notice the super glossy skins everywhere, as well as some weird nipples and overall the same breast sizes minus some very few exceptions. These tend to get better the further you go in the game, but keep that in mind when you play.
Overall, a massive game with stuff you won't find so easily in other titles, and despite many of its flaws, it does the most important job the best: being just a porn game with crazy shit for sick bastards.
