Slender and beautiful Mai Shirosaki finds herself surrounded by unpleasant men—so-called "kimo men"—who are repulsive enough to make normal interaction unbearable. Helplessly forced into sex with them, she is kidnapped and trained by these men who have long fantasized about imprisoning and dominating girls. Despite her suffering, Mai cries out, "No, stop! But it feels so good!!" as one kimo man after another takes his turn with her.
