It's a semi-cute story, not very original, but that's ok.
If you like incest oriented games this one is right that.
Trying to say something useful without spoilers:
- Story is not just unoriginal but also quite basic, too simple.
- Characters are not bad, but quite simple - given the story there's no context or daily life so it's somewhat understandable, still it's hard to get attached to any of them as they don't really have a lot of personality
- Dialogues are not great for sure but not particularly bad either
- Sex scenes, there's quite a few, they are fairly sexy, but also... simple.
- Interactivity - don't look for it. It's just porn.
- Renders - I like the women, they feel somewhat generic, for instance the daughters feel and look kinda alike. The most different looking girl is the sister I think and I like her for that reason even though she's less 'perfect' (avn/ish). The mom / aunt look pretty and sexy but also old, age is never well represented in AVNs but I feel this is less bad than typical, to a level that made it enjoyable and somewhat believable that they are a generation older. That's hot - the entire idea of milfs / matures / especially moms is that they are a generation older.
I like incest stories but there's not a lot of 'forbidden fruit' feeling to this, characters give in very easily. It's explained so it's consistent which I appreciate, really do it just feels a bit less engaging because of it.
I struggled with the rating, let's call it a weak 4, but I like the true incest nature, I like how mom / aunt are actually older, and some of the incesty sexy talk is pretty hot. Also - a completed game! That's worth an extra star in itself.
Don't expect a complex interactive thing, but if you're into fucking entire family from innocent daughter to loving mom, you'll still like this one.
