The ultra-pure beautiful girl "Ren Koino" takes on the legendary BDSM drama "Misery of M"! Her body is bound to the extreme, tied so tightly that not even her fingers can move. Rough hemp ropes dig deeply into her soft, pale skin as pain transforms into pleasure. Ren, the 17th-generation head of a traditional school of etiquette, is forced to join a rival faction due to financial troubles—but this group worships lust and bondage, a corrupt and depraved sect. The agony of the rope restraints gradually turns to ecstasy, and Ren becomes increasingly soaked and unraveled. Ultimately, she is trained to the point of drinking down semen, completely dominated throughout the process.
