A high school girl, unloved and isolated, submits to a man's training. "If someone needs me..." she thinks, accepting the discipline to fulfill her own desires. The training escalates gradually—drinking urine, public urination, urinating on balconies, defecating in her panties on cold, windswept rooftops. She's forced to walk in broad daylight with a nose hook and mouth gag, or endure walking through a hotel wearing only her gym shorts. She's made to perform outdoor blowjobs, and her sanity slowly unravels. Ultimately, she takes the extreme act of taking a bare penis deep inside her shaved pussy. The contrast between her fearful expressions and her praised, smiling face highlights her unique allure.
