A woman ties an M man to the bed and mercilessly tickles him nonstop for 22 minutes in this extreme, boundary-pushing work. Amid overwhelming ticklish sensations that feel both agonizing and intensely pleasurable, a deep, complex emotion emerges. Laughing while excitedly chanting "kochokochi," the woman's sadistic nature shines through. Sustained tickling over such a long period demands immense physical stamina and focus from the tickler, but the woman, a former athlete, remains strong and relentless throughout. As she tickles him, she gradually undresses, performing a live strip show—an eerie yet highly stimulating experience for the bound man. Her backstory—joining the Amateur AV Director Training School due to insufficient stamina as a tickling fetish worker—ironically highlights the high satisfaction level of her performance. The video also features nipple tickling, adding further depth to the domination. Please note that the same scene is repeated with different camera angles.
