My main issue with this and similar games is that they aren't actually games. They're essentially just kinetic novels made in RPGMaker.
I'm probably going to express an unpopular opinion, but in my view, a good NTR game ( a game) doesn't need a good story. Just like a good game about corruption, an NTR game needs an element of struggle for the player, as well as non-obvious choices.
Is the story in Rinatest good? Well, I'd say it's average. Is it interesting to play? Very much so (it's especially nice that it doesn't have those famous clouds with hearts screaming "step here / talk to him to get a scene," and the variability isn't just in the endings but also in how the game day unfolds).
Do people really love NTRpg2 and Henteria for their plots? Or is it perhaps for how that story is delivered and implemented through the game engine, and it's precisely the combination of these things that matters? That's the reason why I stopped following SAO2. Fujino was never a master storyteller, but he created good scenes and used the mystery element effectively. However, when the game grew to such a scale, it stopped being interesting. He doesn't change the formula or introduce new mechanics or mini-games; essentially, you just go from point A to point B to watch a scene, and then wait for a new update (it seems he even forgot about the phone and the blog, which previously served as sources for scenes).
Considering that NTR and corruption go hand in hand, we can also recall Karryn's Prison, where you really have to put in effort to keep the heroine pure. It doesn't give you a direct "have sex / don't have sex" choice. That choice is made through gameplay mechanics.
