A video of the beautiful female teacher Karen urinating is spreading around the school. This is where it all began... Every time she gives her body to fellow teachers and students under the pretense of keeping it a secret, her ego and pride fall to pieces. However, before she knows it, the shameful urination turns into pleasure, and even the joy and pleasure of being scorned envelopes her. Crouching down, from the front and back, standing with her legs wide open... the entire film is a continuous series of videos of her urinating in a furious manner. The final chapter of the three-part series on the Karen Kisaragi teacher peeing series.
