My sister, Asami, who is late and has no knowledge of sex, was worried that her boyfriend didn’t seem comfortable. His younger brother, Kun, who consulted with her to comfort her, decided to let her observe for her older sister who had never seen her cock. However, both of them got excited and handjob, fellatio, and shooting. From that day on, my younger brother Kun will be a practice stand.
