A number of iron restraints placed in an inorganic room ... Eight women fixed there. No matter how pretty and beautiful a woman is, it's the last time she enters here. A terrifying place that can be regarded as just an anal toy. Whether crying or crying, the iron restraint bites into the soft skin and cannot escape, and the unprotected anal is overrun by mysterious men. The wrinkles of the anal are carefully appreciated, and when the frightened anal is tingling, a big dick, various foreign substances, and a torture tool called "pear of anguish" are screwed in, the woman's M sex is awakened, and someday Pain turns into pleasure.
