I want to peek into the open-air baths and rooms of young women at hot spring inns! However, after investigating the most popular hot spring inns, I found that it was impossible to take secret photos using the methods used up until now...So! I developed a new weapon, the "voyeur helicopter"! I took secret photos of the girls' rooms and open-air baths from above! I'll show you their indecent appearances! In the private open-air bath on the roof, I was able to successfully take secret photos of sex!
