23-year-old Mei from the Kansai region. She had always lived an ordinary life until one day, she suddenly underwent a perverted awakening. The transformation began with a seemingly innocent pose, then her anus started expelling massive amounts of retained waste. The volume was far beyond normal—scenes of defecation are shown in full force, ranging from thick, giant logs to soft, slimy, dripping diarrhea that makes squelching sounds. The foul stench released throughout the process is vividly depicted, creating an impressively realistic and authentic experience.
