Forty-year-old married woman Reiko is sold to an SM dominator to pay off her debts. Her mature body is bound tightly with ropes, her beautiful, innocent face distorted by nose suspension and a gag. Her well-matured pussy is forcibly violated with vibrators and electric stimulators, while the heat of candles and sharp slaps echo throughout the room. Reiko's moans drip with lewd fluids as she is repeatedly impaled by an enormous cock, drowning in a depraved pleasure that continues long after her first climax. Without exchanging words, she succumbs helplessly to the raw, authentic ecstasy of this brutal bondage SM domination, becoming irresistibly entranced by the humiliation.
