In this subtitled Japanese BDSM masterpiece, Aiaoi, the stern mistress, punishes her disobedient slave with an enema, inserting the nozzle into his resistant, puckered hole. She watches, amused, as he squirms and cries, his humiliation her gratification. Later, she feeds him his own waste, a symbol of his complete submission. Bound and at her mercy, he endures her cruel, yet thrilling, sexual torment.
