TLDR; This game is... not very good. It's definitely not 5/5 like some have given it, but it's also not so bad that it's a 1/5 either. Anything in the middle is more accurate, though I really don't think it's worth more than a 3/5, even if you can handle the horrible writing. My actual rating would be a 2.5/5, but since I had to round, I rounded up because I appreciate when devs actually complete their games.
Unlike a lot of others who gave this game poor reviews, I actually like the models. I think they are hot -- if not unconventional. The sex scenes were okay at the beginning, and got better later. But that's were most of the strengths lie. I think if you are lukewarm on the models, this game will be a 2/5 for you.
The writing in this game is where it completely falls apart. The dialogue is juvenile. The characters -- especially the MC -- speak and behave like they are 12 years-old.
I can handle characters acting in unbelievable ways in order for sex scenes to happen, because it's a porn game, that's par for the course. But this game took it to a new level, the MC spoke like an actual child, and the characters acted with no sense of believability or even consistency. Just bad character writing. The plot itself is also trite and uninteresting, existing only to make the characters have sex.
All-in-all, this game really does not have much going for it. If you're like me and you like the models, do yourself a favor and either download the Gallery mod and just watch all the scenes, or just use the walkthrough and skip all the dialogue. If you don't like the models that much, don't play this game. The story is not worth playing and I only completed the whole thing so I could give a fair review.
