Your kind and serious older sister. The older sister, who has been living with her for a long time, suddenly became a gyaru in both body and mind after falling in love one day. And your older sister, who has lost her hoop, begins to attack you with her suppressed sexual desire, and a harsh life of repeating sex all the time begins. *This work is equipped with a "flashback system" in which the memory of the once kind sister is cut into the image while being violated by the gal sister.
