Miu finds SM goods in the room of a senior she admires. Her desire to be trained grows in an instant. She feels lewd, naked and restrained. She becomes addicted to sex in the midst of masochistic pleasure. Miu visits her room without panties or bra. She crawls on the floor like a bitch, savoring her slave status. She climaxes many times as her sexual senses are stimulated with oil. Miu becomes more and more of a slave to the man as she is immersed in sex. "In front of you, my love, I become a masochist."
