One summer day, my two younger sisters wanted to watch a fireworks display, so we went on a one-night, two-day trip. Without our parents knowing, we had been engaging in incest repeatedly. As soon as we arrived at the inn, my aroused sisters sought sex. In the outdoor bath, it was "Shizuku," and in the room, it was "Mio"... And after the fireworks festival, I repeatedly had unprotected sex with my two cute sisters in yukata until dawn.
