This game is incredibly strange. For the most part it's all a bunch of stuff that everybody's seen before: a young girl getting gradually more perverted and corrupted, incest scenes with a creepy brother, and all the uncomfortable sexual advances from strangers. But then it tries to do other stuff and it feels poorly-implemented, like the girl/girl content that still forces you to suffer through scenes with (gross) dudes to get to it, a horrific impregnation via alien, and a... tribe of people that kidnap others? A muscular lady that everyone in-game implies is some desperate ugly chick who won't ever get a man, but looks... perfectly fine and attractive? A girl who supposedly has a dick but the game just doesn't have any content for? (Also, why the fuck does that one gross dude in the school fly a goddamn airship???)
The scat scene, even with the warning, is also extremely out-of-left-field, especially because there's just... no other scat scenes anywhere else in the game? It'd be like playing a game primarily focused on some other, relatively-vanilla fetish, but you're one choice of dialogue away from stumbling upon a guro scene that doesn't fit the rest of the game.
The "NTR Club" also feels misleading; sure, it's all about girls cheating on their male boyfriends/husbands, but the name and "warning" don't say anything about it being girl/girl content, so if you're actively looking for the girl/girl stuff most players wouldn't think that's one way you could find it.
