First off, you need to know that this is an extreme BDSM visual novel that includes scenes such as branding, sticking numerous needles in someone, and nearly drowning someone. What's amazing about this game is that the render quality is better than a lot of games made in the past year. The story is somewhat rudimentary as it follows several people, specifically a sister duo who both very extreme masochists and sadists. The sex scenes are well done and they showcase the total craziness of the sisters.
