In this adult classmate role-play, three childhood friends attend a fireworks festival, but a sudden downpour separates one of them and leaves me alone with Natsu. I had always seen her as a slightly childish, sister-like friend, until her soaked yukata turned sheer enough to reveal her underwear and made me notice how womanly she had become. As the rain worsens, we take shelter in a love hotel, where one stormy night pushes us across the line and ends in a creampie.
