Nagisa-chan, an underground idol who excels at singing and squirting, appears. We check her tongue. I'm really looking forward to seeing Nagisa-chan's reaction as she says, "My mouth is crazy! I've never had this filmed..." Her tongue is relatively long for her small face, with a bumpy surface and a nice shape. Immediately, we collect dirt with a small metal tongue brush. Scrubbing thoroughly all over, including the base and sides of the tongue, we collect a large amount of white, paste-like coating. Next, using an extra-large tongue brush, the amount of bubbly saliva is incredible. This also collects a solid amount of white coating. Nagisa-chan looks cute as she resists having her saliva smelled. Finally, a perverted man in that line of work checks the smell of the collected tongue coating and saliva. Nagisa-chan resists, saying, "No way, I've never had it smelled before..." The development piques viewers' curiosity about what kind of smell it is.
