There is no futa nor explicit genitals. Also, the characters have no romantic/sexual relationship since they're all siblings.
Can there be an option to show genitals and for there to maybe be incest?
Sorry but no
So wait, the game is tagged erotic but there are no genitals and no sexual relations?
that is exactly what i thought. Eroge are sex stories, I don't think you can have eroge without some kind of explicit sex. was all excited too, siblings, zodiacs, eroge! still looks fun but not at all an eroge
