On the night of the fireworks festival, a sudden heavy rain throws me off. I rush into a love hotel with my childhood friend and classmate and take shelter from the rain. Creampie

A fireworks display attended by three childhood friends. On the way back, it suddenly rained heavily, and I got separated from the other one, leaving me alone with Natsu. Natsu was a little childish and we were close childhood friends, like a little sister, but lately she's suddenly started to look like a girl and I've started to notice something strange about her. Her underwear was slightly visible through her yukata, which was drenched in the rain. For some reason, Natsu suddenly looks sexy, and I can't stop my heart pounding when I see his different expression than usual. As the rain continues to get heavier, the two rush to a love hotel. What happened overnight, when this heavy rain made us go crazy, even though we weren't supposed to cross the line.
