This installment of Tickle Experiment Lab from Fetish World features Rumi-chan and Kaori-chan as test subjects, focusing on the intense reactions of highly sensitive girls. Their bodies are subjected to relentless tickling stimulation across various erogenous zones, producing nonstop screams and cries of agony as they writhe and struggle in vivid, realistic detail. During interviews, their speech becomes so hysterical that words are rendered unintelligible. Notorious for its extreme nature, this controversial release has gained attention as a work said to push subjects to the brink of trauma. (Smile Lab.)
