It's a Scene Viewer and should be rated as such. With that in mind, it's alright. So what makes a Scene Viewer good? The animation needs to be great but also have variety. The girl needs to be attractive but also expressive. There doesn't need to be a complex story but there has to be a reason for the scenes. No gameplay is required, just the ability to change scenes. So lets break it down.
The animation is pretty good and there is a decent amount of variety. The scenes themselves could use a little more significant movement (and maybe a little more nudity), but otherwise I have no complaints. The girl is fairly attractive and is expressive enough to keep her tsundere attitude while giving enough expression to make her not seem like a cardboard cutout. There's a minute amount of story that sets up the situation but doesn't lead anywhere. It gives reason for the sex and that's all that is really demanded for a "middle of the road" rating for a Scene Viewer's story.
Overall, it's as 3 out of 5 stars as you can get per the genre. It's definitely worth the time as it's incredibly short and you don't need much effort for the reward, especially if you're into maids.
