Your parents leave overseas for work, and you're home alone with your stepsister, Kurumi. Kurumi is a bright and energetic girl who loves to tease you. She knows exactly how to flirt and be naughty around her virgin older brother. Even if it's just by marriage, you know you shouldn't get involved like that with your younger sister, but... You might just give in to the cute Kurumi and cross a line that's forbidden to an older brother...​

It's a two hour game and it's censored by default, there aren't that many animations and the ones we have aren't that good. Overall it's not a bad game, the uncensor mod works great, but it's average overall.

Cute The way the story is told and how the bond deepens between the main characters is so cute! I really like the fact that the game is quite linear and there aren't any side objectives or things to unlock…

Pretty good game for the most part, falling short in a couple areas though. First off, I don't get why the inseki thing still existed in 2024 when this was made. It was old twenty years ago, archaic ten years…
