A documentary depicting girls who declared, "Please train me as your anal sex slave," as they are completely controlled in their excretory functions and fall into the status of fecal receptacles. This release contains records of actual anal abuse training experienced by 10 genuine female masochists under strict ○ prohibition. Part 1 includes two segments: "Reina, the perverted young wife performing a public excretion show," and "Kaoru, the woman who wishes to live as a masochistic toilet servant," both vividly portraying intense psychological and physical domination.
