An exclusive document recording the daily lives of a couple kept as livestock slaves has arrived. True masochist male servant Yoshio (31) and female servant Nozomi (29), who has fallen to the level of a mere flesh vessel, pledge absolute loyalty to their sadistic masters, embodying a perverted yet pure love in this M-themed documentary. Part 4. Note: some audio distortion occurs in certain scenes due to the original master source, not a defect in the production.
