A film featuring 24-year-old Nayu, who works at a confectionery factory, indulging in aggressive M-man torment. Standing 163cm tall with a foot size of 28cm—remarkably large—she explains that her feet gradually grew larger since she began swimming. The encounter began when we noticed her astonishing foot size by chance at a commercial facility and approached her. Though she initially appeared gentle and shy, she secretly harbored a long-standing desire to dominate and tease weak men. Discovering this side of her made the experience far more intense—not just simple M-man bullying, but an exhilarating revelation of her deeply hidden sadistic nature. During filming, her face was not shown, carefully kept out of frame, contrasting her cute, small-animal-like appearance with her dominant, S-treatment during the sessions. At first, she hesitantly stepped on the man with her feet due to their initial meeting, but as her large feet pressed down, he was reduced to feeling like an inferior creature, mercilessly crushed without restraint. Her discovery of his sensitive nipples led to her tormenting him with her toes and hands, delighting in making him cry out—her mischievous grin utterly irresistible. She frequently forced him to lick her large feet, which, despite being soft and feminine, were sizable with long toes, offering substantial texture and taste. If his licking was too weak, she harshly shoved her foot into his face. Finally, she applied a vibrator directly to his erect cock, repeatedly bringing him to the verge of orgasm only to pull it away at the last second—orgasm denial highlighting her cruel, dominant nature. Begging for release, he eventually climaxed from the vibrator, ejaculating an astonishingly large amount, overwhelmed by the built-up excitement. Nayu stated she thoroughly enjoyed the M-man torment, revealing a cold, sadistic side completely opposite to her appearance—an experience that truly showcases her captivating allure.
