Obedient Flesh Slave. A girl named Hana, who has been trained to suit a man's convenience since about three years ago, has been accommodating his unreasonable desires and accepting his manhood devotedly. She has awakened her own sexual desires and began to feel the joy of living, eventually becoming a body that cannot survive without a man. Hana is introduced to someone by that man. Taken to a hotel, Hana's body is bound and trained. This is a documentary training video that captures Hana's body swaying between pain and pleasure.
