Keisuke, who reunited after visiting the grave for the first time in a few years, got off the train with his cousin's sister at the station on his way home, and decided to go sightseeing with his aunt <Yuka> in his hometown. Yuka, who reunited after a long time, has become an adult woman with huge breasts and sex appeal, unlike in the past, and Keisuke who is still a virgin and has no immunity to women is excited and unimaginable. It was done. Then, when the sightseeing in the city was over and I was about to go home, it started to rain suddenly, which caused the train to be suspended, and the two of us had to stay overnight at the hotel.
