A beautiful slender female spy is captured, stripped completely naked, blindfolded, and bound in an X-shaped crucifixion position. She is then mercilessly tickled by Matsushita Kazuo (Doctor Matsushita), the world's greatest tickling master. Unable to withstand his unique and relentless tickling techniques, the female spy writhes and twists her body in uncontrollable laughter. Her desperate, intense reactions are the highlight of this video. Confident in Matsushita's tickling skills, strong challengers gather for the "Tickling Technique Training Seminar" to try making this female spy laugh herself to death and earn money. Please note in advance that the same scenes are repeated from different camera angles.
