A treasured original production by Kazuo Matsushita, renowned as a pioneer in the tickling genre. This fourth installment in the female spy series delivers unprecedented intensity and eroticism. The protagonist is restrained, immobilized, stripped down to her underwear, and ultimately tickled while completely naked—an extreme experience like no other. Her reactions and expressions reveal a depth beyond mere tickling, exposing raw vulnerability and sensation. Please note that the main feature may contain audio-video sync issues or noise, due to the characteristics of the original master material.
