Today is a day to play with mud, wearing a black swimsuit. Nao is curious and enjoys trying all kinds of materials.

Today we start with enjoying the feel of mud.

First up is a mud dunk from the face. Once his face is covered with mud, he applies it to his body. Once the body, back, and buttocks are coated, we apply it again to the face. Once all are painted, we will take off our swimsuits and get covered in more mud. Then, after striking a mysterious pose for some reason, they do a mud dunk, take it in their mouths, and that's it. There is a short scene at the end where the mud is poured over her head.
