This video has English subtitles. Cloudy is the most clumsy and disobedient ballet student under the stern hand of her teacher, Kai. Late again and without her ballet shoes, Cloudy is a mess of poor flexibility and balance, a mockery in the graceful world of ballet. Kai, at his wit's end, decides to teach Cloudy a lesson she'll never forget. He makes her into a pair of black, long, high-heeled ballet shoes, a stark contrast to the traditional pink. But even with these, Cloudy's clumsiness prevails, her hands flailing uselessly. Kai secures  them behind her back with a leather jacket, trying to improve her posture. Her whimpering and shaking only fuel Kai's frustration, leading him to silence her with a ball gag, its leather panel pressing against her lips. As Cloudy continues to fail, Kai snaps. He escalates her punishment. He ties her into a strappado, her arms wrenched above her head, her toes barely touching the ground. Her cries are muffled, her suffering palpable, yet Kai remains unmoved. As a last desperate attempt to instill strength and discipline, Kai binds Cloudy into a full hogtie. Her body forms a perfect arch, her breasts pushed forward, her vulnerability on full display. She struggles against the ropes, whining and writhing, but Kai is relentless. He leaves her to fight against her bonds, hoping the rough lesson will finally penetrate her thick skull.
