This is a survey report on women who enjoy drinking alone in open-air baths during weekdays. The first is Nagisa (23 years old), a busty childcare worker with a high sex drive and a masochistic personality. The second is Azusa (22 years old), a cheerful, tomboyish, busty female college student who came with her boyfriend. The third is Mizuki (24 years old), a party girl who hasn't had enough, spending her last night as a single woman! The air is thick with the smell of alcohol and the sexy scent of yukatas, creating an erotic atmosphere! A trinity!!! Massive, vigorous ejaculation!
