The model is Nao. She is wearing a blue swimsuit and a heart ball gag today.

Today is Nao's first experience with the material. It is a carbon powder called bamboo charcoal. In Japan, a mysterious food product called the Black Food Series is sold. These include bread and soft-serve ice cream.

The powder is mixed with oil.

Now, we will apply it starting with the hands and feet. She enjoys the different texture from paint. Next, she applies it to her buttocks and back, and then to the upper part of her body.

She takes off her swimsuit, but by Japanese law, the local area is taped. If it is visible, mosaic will occur.

Finally, the face is soaked. What will they look like? After being soaked in black oil, she has a beautiful shiny appearance. The thing fitted in her mouth is removed, and she is free. Her whole body becomes black and shiny, and she looks happy. She dunks a few more times after that. Did you notice? This is oil, so unlike paint, there is no pain in the eyes. It even blackens the eyes.

Finally, he finishes with a generous dab.
