"You can call me Onii-chan, right?" One day, my father remarried. What appeared in front of me as a "sister" was... how!She was an anikos AV actress who was always onaneta!Her name is "Aoi".At first she thought it was just her imagination, but as she peered into her, she became convinced that she was the same person!If she tells "Aoi" about this, she will surely be at my mercy!She might be able to do naughty things with her who was always chewy!And when she enthusiastically approached her core, she unexpectedly developed for some reason... An erotic life that is tossed by the AV actress "sister"!
