A short-haired, 145cm tall petite and cute Mari-chan reveals footage of herself checking her tongue coating. She is aware that "her tongue coating has been bad lately" and is seen scraping it off with her fingernail and sniffing it. Even from the cameraman's position, her white, fluffy tongue is clearly visible. Despite her small face, it's wide, and Mari-chan has the best tongue. First, she uses a metal tongue brush (small) to collect the dirt from her tongue. Scraping thoroughly from the base to the sides, she collects a large amount of white, paste-like coating. Next, she uses an extra-large tongue brush, and the saliva's viscosity is remarkable. This also yields a good amount of white coating. "It's a bit cloudy... Don't look~ (embarrassed)," says a shy Mari-chan. Finally, she has a pervert man who's into that sort of thing smell the collected tongue coating and saliva. We can't wait to find out what kind of smell it is.
