This one was ultimately better than I was expecting. It has multiple endings, though more like two main endings with variations to each which can include NTR. I did not pursue these endings so I can't speak to their quality.
The story was more lengthy-feeling than I see with games like this, and I enjoyed the dialogue with all the characters who I thought were quite well designed.
The two main paths are "friendly" and "horny" (or I think more accurately "love" and "lust" though they are referred to as the former in game files) paths, based on a point system for those two stats respectively. Choices you make raise/lower those points at certain times and ultimately drive the path you're on. These paths have very different endings and personally I thought the Friend one was the best option.
The lewd scenes were well done as well, though some had some questionable lighting IMO.
The only things that are a mark against this game is that while the choice/path system seems relatively in-depth, it's very hard to determine what path you're taking when, and what the choices mean sometimes. There isn't any indication of important choices except one instance - which as far as I could tell had no actual effect. Even with skipping there's a lot of story to blast through again if you felt you made a wrong choice somewhere, and the walkthrough provided is IMO not very comprehensive.
The other is that for as decent as the story was, the ending was quite rushed. It definitely felt like there was considerably more game to play, story to learn, and maybe endings to unlock after the Spin the Bottle segment, but it just goes into a series of summary slides instead, which is disappointing. I don't know anything about the circumstances of the developer on this game but at least it HAS an ending, instead of being dropped. FWIW I did enjoy the ending I happened to get, despite it not being quite what I was hoping for.
Overall, worth a play, but I very much recommend a walkthrough - though you may have to find or make an easier-to-decipher version than the "official" one.
