F-cup big-tits female masochist "YAMAMO" visits Tanbi-kai, openly confessing her deepest desires. She pleads, "Please defile me with filth," uttering a self-degrading yet sincere request. In response, she is subjected to nasal torture, rope bondage humiliation, and painful blood-congesting breast bondage. She undergoes training to become a "human fountain," forcibly spraying excrement onto her own face, which awakens even deeper submission and masochistic cravings within her. Her body overflows with pain and shame, her appearance overwhelming all who witness it.
