Cat-eared phantom thief Cat's Eye sneaks into a room where treasure is kept, but the master has already anticipated her move and set up security traps. Unaware of their presence, Cat's Eye is seized from behind. The security system threatens her and forces her onto a bed. Her punishment, unlike pain or suffering, is the overwhelming pleasure of tickling! Helplessly writhing and bursting into laughter, Cat's Eye struggles desperately. Finally, tickling her bare feet drives her to the brink—she climaxes involuntarily.
