A veteran female detective who failed an undercover investigation and was imprisoned is punished with an sm interrogation. She is stripped naked, revealing her big breasts. Even her brave attitude only fuels the sadist's sadistic heart. A scream of joy with a masochistic voice to the relentless whipping. No one comes to help even if she cries or screams. Her crotch rope is wedged into her crack, she is given pain with a large number of clothespins on her nipples, and she experiences the forbidden pleasure of an enema play. The joy of being abused, from which there is no turning back, drives the woman mad. The mature woman with big breasts, who is implanted with an anal abuse fetish, suffers a mental breakdown from shame and humiliation!
