Satomi-chan is a graduate student with long black hair and is an intelligent woman. She is an intelligent girl who seems to have nothing to do with AV for the rest of her life, but in fact, her grey brain cells are full of naughty thoughts! She has a strong Kokoro to explore sex, and finally comes to the filming site, dreaming of being penetrated by a big black cock. In her desire for a big cock, she submits to the obscene demands of the perverted middle-aged men on set, and continues to cum until her thighs are dripping wet with love juice. When she takes the big black cock given to her as a reward into her mouth, she goes crazy, shaking her black hair and rolling her eyes back!
