Don't you hate it whenever you see your crush or favorite porn star and you think about your sister? Well the main protagonist doesn't. This hentai revolves around 2 siblings who are very close. How close? Close enough to talk about their love lives....... while banging each other. Yeah, the story was something. It's weird how the older sister talks about potentially getting married to her boyfriend while her younger brother is pounding away. If you're into wholesome incest... you'll kind of find it here? The you know what scenes are very vanilla. The fact the sister is technically cheating on her boyfriend isn't a major factor inthe story so if you hate that stuff, you'll be fine.
As for animation, it's decent. Like most hentai, it does the job it needs to do.
This is pretty much a basic incest hentai. If you're into that, have at it.
