YA005-01 Mizusawa Tsugumi’s White Residue Tongue Coating Collection

Using a wide, rounded tongue brush, I had the coating on my tongue gently scraped off and collected in a dish.
Each time the brush was moved, the fluid on my tongue turned white and foamy, which was oddly suggestive.
As for the smell…
Tsugumi-chan seemed annoyed when I coughed a little.
So I said, then smell it yourself!
When I asked her to smell it, the word she gave back was
human
Yeah, that sounds about right
