JUFD-704 Eleven months of incestuous life continuously seduced by my little sister Soru Shinome

My sister Sora and I were good brothers even from the outside. But now that Sora has grown up and I had a girlfriend in college, the time we spend together as siblings has been getting less and less. One day, when she thought she was having a good college life, she saw the situation in the sky. Perhaps she felt pity for me, and said, "Would you like to be my girlfriend?" From that day on, the days of being seduced by the aggressive sky began every day.
