Spoilers ahead. So the story goes the two are stepsisters who've fallen in love with each other. Okay, they're lesbians which is interesting. They get blackmailed by the main antagonist who ends sleeping with them. Then he forces them to sleep with other guys. It's a hentai so the plot shouldnt be that well developed in my opinion. If you're into extreme kinky stuff like gangr*** and group stuff, then this is for you. I like it. It's based on a h manga. I found the story to be unique. I only wish the last 2 panels of the manga were animated or shown inthe anime.
