"This weekend, I'm going to take my beloved stepfather on a trip with my first paycheck." For the father who raised her for 20 years, Nao gave him a hot spring trip as a present. It was supposed to be a fun time for the two of them, but when they entered the mixed bath together, the father saw his grown daughter's naked body. Knowing it was wrong but unable to control himself, he raped her. In the room, in the bath, in the hallway, Nao was repeatedly raped by her stepfather during their one-night, two-day trip.
