Well, I carefully observed the armpits of 70 girls, including interviews! Take close-ups of armpits that you can't usually see openly, and check how the armpit hair grows, the range, the thickness, the thinness, and the processing status! Armpit licking, sniffing, blowing on, tickling, etc. to arouse shame. It's close to the real and naked armpit circumstances of Doki now!
