One day, 'mai' visited her uncle's house. Mai, in the midst of puberty, was intensely curious about male bodies and penises, spending every day masturbating and unable to focus on her studies. 'I'm a bad girl. I need to be punished...' Memories from her childhood resurfaced. Her uncle, who used to scold her. Only my uncle can punish me... And so began the masochistic training. Her immature buttocks were spanked until they turned bright red, and her budding breasts were bound. Mai began to experience the pleasures of masochism.
