A married woman taken deep into the mountains is bound and restrained, subjected to extreme punishments including enemas and drinking urine. Trembling in fear, she is hung upside down and flogged. Suspended upside down from a tree, she endures flame torture until, at the peak of terror, she's forced to urinate while still hanging. Hoisted upside down in a crucified position from the ceiling, her buttocks are tormented with blow darts and needles, culminating in fireworks exploding around her. Fireworks are inserted, lit, and launched directly into the married woman's pussy in an intense, shocking display. Outdoors, she's hung upside down from a metal tower, completely under the control of her master who whips her relentlessly. Bound to tables and pillars, she's tormented with electric massagers delivering painful currents and burned with light bulbs. Restrained on a table, both her holes are violated with glow sticks, continuing a relentless series of extreme tortures. Titled "Oni★Do," this work fully captures extreme expression and the master's overwhelming desire to dominate the married woman.
