The continued sexual adventures of a brother and his cousin from the Studio “gomasen(3D)”. The second part of the story came out exactly six years after the first part of “Sex Lesson for Brother” in 2011.
Sister continues to love brother and to read a number of books. Once the brother finds in her room an unusually depraved fiction. After reading the lion’s share of it is written he was very excited and began looking for my slutty SIS.
