Director Shimazu Shikou oversees the training session of two married women who volunteer for SM, delivering an extreme experience where harsh corporal punishment merges with sexual domination. From the start, the director issues forceful commands, ordering the masochistic wives to remove their panties and crawl naked on all fours. They are then forced to obey bizarre instructions, such as drinking water from puddles, enduring the humiliation while swallowing. This is followed by intense physical punishment including spanking and kicking, with their painful endurance depicted in detail. They are given enemas using river water, shown struggling to hold back before involuntarily releasing. Forced to walk on all fours and urinate with one leg raised, they are treated like dogs, emphasizing their degradation. Bound to a pillar, cigarettes are lit and shoved into their nostrils, forcing them to inhale smoke, while whip lashes torment their bodies. Needles are inserted into their buttocks—already stimulated by flogging—layering pain with shame. With legs spread and restrained, catheters are inserted into their urethras, inducing forced urination. Once their bladders are empty, the men's urine is pumped back in, creating a disturbing reverse infusion. Needles are also inserted into their vaginas, anal beads and dildos forced into their anuses, and various restraints attached all over their bodies. They are commanded to shake themselves to ring attached bells, illustrating complete subjugation. Multiple injection needles pierce their breasts, emphasizing total bodily control. The two masochistic wives bring their own submission gear, shown later walking naked on all fours through a stream. They endure extreme procedures such as having a speculum inserted into their anus, followed by their master's urine and live loaches being injected for an enema. Back indoors, they are tightly bound and blindfolded, flogged and teased, then strapped to chairs with legs spread open and subjected to electric torture via low-frequency massagers. Electrode rods are shoved into their anuses, driving them to the point of unconsciousness—scenes of ultimate fusion between physical punishment and sexual domination unfold relentlessly.
