The model is Ren.

She will be transformed into gold today. She will wear a purple swimsuit and, little by little, we will paint her gold. After some paint, she will be topless. After painting her body, we will paint her face. She will put it in her mouth and turn all of her face gold. Now she is transformed into the most remote figure from a person. She takes everything off (oops, Japanese law prohibits full genitalia, so it does not show), puts it on her head, enjoys the feeling, and the golden coloring is over.

After this, the girls are covered with the leftovers used in the yukata scene. Isn't this a new art form? I was suggested to do this. She seems to be enjoying herself even though she has gone from gold to black. From the results, it was a great success. I will put the photos in a place where you can see them for free.
