On the night of the fireworks festival, a sudden downpour drove me crazy. My childhood friend and I rushed into a love hotel to share a room and escape the rain. (Tojo Natsu HMN-743)

I went to a fireworks festival with three childhood friends. On the way home, it suddenly started pouring rain, and I got separated from one of them, leaving me alone with Xia. Xia is a bit childish, a close old friend like a younger sister, but recently she's suddenly become very womanly, which has started to pique my interest. She was soaked through, and I could vaguely see her underwear through her wet yukata. For some reason, she suddenly looked very sexy, and seeing Xia's unusual expression made my heart race. The rain intensified, and the two of us rushed into a love hotel. What shouldn't have been a one-night stand, driven mad by this downpour, became something more.
