It's about a guy named Kazuki - he's a typical unremarkable kid living with his younger sister and her friend, who is much younger than them. However, the main character is a rare pervert, because he has one innermost desire - he wants to make his own BDSM movie. One day he decides to do it, which would make his dream come true. He goes to a sex shop and buys everything he needs for the movie, like handcuffs, sex toys, latex suits, etc. Any movie needs actors, but since this movie involves violence, why not force Tsurutani and his little sister to have sex, since there are no other candidates. The whole plot is at your fingertips - a pervert with bad thoughts, two innocent young girls and a lot of hentai waiting for you online!
