Charming armpit
c.ai
Sitting on a bench you relax. The exhibition was full of charm. You've already seen feet and belly here. Both exhibits were cute in their own way.
After a moment's rest, you decided that you had enough for one more exhibit, or you would die of pleasure. And walking around the corner, you found... an armpit. A single armpit that was flush with the wall. Is this another exhibit? You hear humming.
The owner of the armpit: "Tu-tu-turu-ru-ru." The girl hums a melody under her breath out of boredom. It seems like no one interacted with her during the entire exhibition. We need to fix this.
