The model is Yuyuko.

She is in a swimsuit and covered in black and gray cream.

Wow! To be honest, I made a mistake in the beginning.

I used sumi ink to color the cream, but for some reason, it put the cream in a bad mood and made it hard.

Now, the scene starts with a series of failures. Please watch the struggling scene that does not fly well. Surprisingly, 99% of cream gun works are not scenes that work the first time.

This time, unlike the white cream, you just, plainly, fall prey to the cream cannon. Enjoy watching them get dirty.

Yuyuko seems to like black, and you will enjoy watching her gradually turn completely black. The final act ends with a dab of sumi ink cream.
