It's hard to evaluate this game. It really depends on what you want out of a game like this.
If all you care about is mindlessly clicking in the hopes of getting a lot of porn, you'll be mildly satisfied. I say mildly because the game logic, which is rooted in sluttiness and lust, makes it really hard to see new content. Sluttiness is not really based on actually having sex repeatedly, but on some arbitrary logic behind the scenes. You're forced to masturbate if your lust gets too high forcing you to choose which scenario you want the enhanced content for b/c masturbating resets the lust meter.
So, on that note, though you can eventually get to some hot content, it's remarkably grindy.
If you care about the story with your porn, you're playing the wrong game. Unless you act slutty with both your boss AND the principal of the school you get an immediate game over. There's not even the pretense of the policewoman actually going to the school to do her job. And your boss doesn't really care if you're doing your job either. It's not like you ever provide meaningful updates to your "undercover" work. You're just at the school for sex, not to solve an actual crime as the premise suggests.
To be honest, the entire game would have been more plausible, if Amy, the playable character with the most content, was a simple schoolgirl at the school and not a cop.
Even though there's a lot of hot content undergirding the game, I was actually surprised that I found myself quickly bored by the game, mainly because it was just a lot of mindless clicking, with no real story.
