Mizuki infiltrates a drug trafficking organization to find a missing junior investigator. After a fight with a thug at the hideout, she is captured. Mizuki is covered in sweat and pretends to be strong, saying "It doesn't feel good!" when tortured to orgasm, but when she is drugged and iron hooks are thrust into her, she can't stand the intense pleasure and goes crazy, urinating! Every time the iron ball presses against her uterus, she climaxes, convulsing and trembling, saying "It feels so good to break my pussy!" and "I want it to be pumped in and out!" A beautiful and strong woman succumbs to the pleasure of being a female and falls into ecstasy.
