For some reason, all men become horny when they come to a hot spring! Hot springs and eroticism are closely linked. In the Muromachi period, "Yuna" were women who scrubbed and washed the hair of bathing guests, but for male guests, they were like hot spring prostitutes who offered more sexual services than that. This is the fifth installment of the popular series "What are you doing to an old lady like me?", which is set in a rundown hot spring inn in the hot spring area. This is a 200-minute hot spring docudrama that is full of eroticism, including beautiful female landladies and waitresses in their 40s to 60s who are beautiful and have big boobs but have no luck with men, single female guests and married couples in their 30s to 60s who are raped and cuckolded by young men at night, 9 people's exquisite sex, and voyeur footage of the women's bath. It is a lewd hot spring docudrama that consists of 10 episodes and lasts 200 minutes.
