An unprecedented new monitoring project is launched with the full cooperation of a certain super public bath! A pair of best friends, amateur female college students, monitor the hidden camera footage installed in the men's sauna and find out the virgin boy! If you can successfully locate the brush, you will receive a large prize! If you lose, it's a punishment game where you are immediately left out! A male customer can't hide his surprise and erection at the sudden appearance of big-breasted college girls wearing only a towel! A must-see is the harem threesome where they fight for the dick while being embarrassed by the virgin dick, but their pussies and bodies are all hot and sweaty!
