[Shousuuha Jikkenshitsu] Kusuguri Egao Kenkyuu [Full Color]

A bound young woman with a disheveled bob squirms and writhes against a metal restraint board as automated brush attachments mercilessly sweep across her bare skin, her desperate cries of "GIVE AAA HAHA HA!!" and "I'M GONNA DIE!!" echoing through the clinical chamber. The clinical atmosphere of cold steel and buzzing machinery is shattered by her helpless laughter, culminating in an involuntary release as the device's relentless stimulation becomes too much to bear. As a scientist's detached voice observes from the monitors, noting her emotions are "A FUNCTION OF THE INTENSITY OF THE STIMULI," the poor subject is left flushed, dripping, and completely at the mercy of the relentless tickling apparatus.
